Design Explained –
Clean, Clean, Clean!

We don’t like mold. We don’t like burnt-on grease. We don’t like calcium buildup. What we do like are intelligently designed products that are easy to clean!

Our final post in the Design Explained series for the year explains how many of our products, ranging from home use to commercial use, are smartly designed to be easy to clean.

Removable Inner Lid of a Rice Cooker

Our product designers and engineers ask fundamental questions like:

  • Are the surfaces, grooves, threads and spaces between components large enough for thorough cleaning but small enough to prevent food from falling through?
  • Are there areas where food can get stuck and spoil and how can they be cleaned?
  • Will the area be easy to access for thorough cleaning?

In answering these questions, they realized that four key characteristics about our product design make them particularly easy to clean – their shape, the ability to disassemble their parts, the ability to remove components when necessary and the materials and finishes used to make the products.

Grooves of the Indoor Grill

Our Indoor Grills, Vacuum Insulated Mugs & Bottles and Vacuum Insulated Food Jars are prime examples of how the shape of the product influences its cleanability. Our Indoor Grills are designed with slightly rounded grooves that prevent food from falling through the grill, while also making it easy to wash away fats and food particles from inside the grooves. Our stainless mugs and food jars have wide mouths, making them not only easy to fill but also easy to clean with mild detergent, warm water and a sponge. And the lid of our Commercial Stainless Vacuum Creamer / Dairy Server is funnel-shaped with minimal threading to prevent dairy from getting stuck in the grooves and spoiling.

One Piece Lid with Minimal Threading

For some products, such as our Vacuum Insulated Mugs & Bottles, the ability to disassemble the components in the lids makes all the difference when it comes to thoroughly cleaning them. So often, liquids get stuck inside lid components, creating bad odors and causing mold. Disassembling all of the parts of the lid allows for thorough cleaning and continued hygienic use.

Disassembling Lid

Our Rice Cookers are just as easy to clean, even with all of the electronic components. The inner lids are removable, so that any stuck-on bits of food and dried on cooking liquids can be washed off without wetting the base of the appliance. The same applies to our Coffee Makers. They’re made with removable coffee filter baskets that can be thoroughly cleaned, so your coffee is fresh, without having to submerge the entire appliance.

Removable Water Tank

The materials and finishes we use in our product engineering directly influence how easy our products are to clean. This facet is integral to each product. Whether it’s the nonstick coating in the baking pans in our Breadmakers or nonstick interior in most of our Water Boiler & Warmers, these surfaces are engineered to repel odors, discoloration and buildup. For example, the inner pans in our breadmakers are removable and can simply be cleaned with mild detergent, warm water and a sponge, just like many of our other products. Our water boilers can get an even deeper yet gentle cleaning with our Citric Acid Cleaner (CD-K03EJU), which dissolves calcium buildup, instead of letting it flake off into the electronic components. These materials and finishes make cleaning and maintaining your appliances much simpler, prolonging their use and your investment.

We hope you’ll check out each of these products, and as always, love it when you share your stories with us. Have a wonderful end to 2019 and prosperous New Year!

Premium Thermal Carafe Ichimatsu Collection (AFFB-10)

Our vacuum insulated mugs, bottles and carafes come with three different types of innovative inner linings…our nonstick coating, our SlickSteel® electro-polished stainless steel, and our gorgeous glass liners.

Zojirushi Glass Liner

Our glass liner is part of our new Premium Thermal Carafe Ichimatsu Collection (AFFB-10). This carafe extends our line of glass lined carafes, including the Glass Vacuum Carafe (AH-EAE10) designed by British designer David Tong of The Division, the Euro Carafe (AG-KB10) and the Premium Thermal Carafe (AFFB-10S/19S).

Ichimatsu Collection

The Ichimatsu Collection carafe comes in white or black finishes and holds 34 oz. or 1.0 L of liquid. It features a one-touch pour, an easy-to-press side push open/close button and a comfortable handle for quick and easy serving. It also accommodates most brewing attachments for added convenience.

The truly unique and smart design of this carafe stems from the vacuum insulated glass liner that makes up the easy-to-clean interior, and the Ichimatsu pattern on the exterior.

The Ichimatsu pattern hold great historical and cultural significance in Japan. The pattern is a traditional Japanese two-toned checkerboard design that originated during the Edo Period (1603-1868) when a famous Kabuki actor, Sanogawa Ichimatsu, wore pants with the checkerboard pattern on stage. His style became so popular that the pattern was named after him. The pattern and finish of the Premium Thermal Carafe pays homage to this iconic design.

Glass Liner

Along with the stylish exterior, the glass lined interior offers an odor and stain resistant surface so beverages stay fresh. The glass liner is made of two layers of strong, durable and hygenic borosilicate glass, molded into the perfect shape at our factory in Osaka, Japan. The air between the two layers of glass is removed to create powerful vacuum insulation and the interior cavity between the two layers of glass is coated with silver plating to give it heat reflecting properties. We even have a cool video showing you how it’s done!

This new carafe is a great addition to your home or office table, and can be used for cold or hot beverages, including water, tea, coffee and so on. Learn more about it on our website or through our product video at https://youtu.be/VuG3K0Uyao8.

Design Explained –
Our Signature Tune!

Our rice cookers and water boilers are practical. They’re technologically advanced. They’re stylish. And they’re…whimsical!

Until 1999, our appliances used standard beep sounds to indicate when the rice cooker or water boiler had started and finished their settings. We realized that so many appliances existed together in our customers’ kitchens that it was difficult to know which appliance was beeping. So, as part of our tradition of smart design, we programmed our rice cookers and water boilers to play a tune instead of beeping.

Zojirushi Rice Cooker Circa 1999

And now we’re known for our whimsical, musical and oh-so-familiar “Twinkle, Twinkle, Little Star” tune which plays at the beginning of a setting. And when a course is finished, the lyrical tune of “Amaryllis” plays!

 

While this feature is definitely one of our more lighthearted and fun ones, there is a solid technological foundation to adding tunes to our appliances. Each appliance needed a microcomputer in the control panel, and that technology was introduced in the late 1990s. Further, microcomputers needed to be programmable, and the manufacturers were able to sequence a series of beeps to make a tune.

We loved it then and we love it now. And so do our fun friends. Just check out this incredibly cute video on our Instagram page: https://www.instagram.com/p/BwNkZ1eh7NR/.

Automatic Rice Cooker & Warmer (NS-RPC10/18)

You know about our microcomputer-controlled rice cookers, but did you also know that we have a great line of conventional rice cookers, too?

Our new Automatic Rice Cooker & Warmer (NS-RPC10/18) adds style, ease and function to any kitchen – with great features and amazing ease of use.

This rice cooker comes in two capacities, either 5.5 cups or 10 cups, which are ideal for making small to large batches of rice. It also comes in two lovely finishes – Tulip and Metallic Gray – that coordinate with almost any kitchen decor.

The rice cooker is simple to use. It features a one-touch operation that starts cooking rice immediately. Simply wash the rice and presoak it for the desired amount of time, and then push on the switch to activate the rice cooker.

The triple heater is built into the bottom, side and lid of the rice cooker, and generates uniform heat all around the nonstick inner cooking pan, cooking the rice at an ideal temperature so that it’s fluffy when done. Once the water in the inner cooking pan is absorbed by the rice, the rice cooker switches to Keep Warm mode, indicated with an illuminated light, keeping the hot rice tasting fresh.

The best white rice is easy to make in this rice cooker. And that white rice can be used to make delicious dishes like Crisp Grilled Yaki-Onigiri and Hawaiian Loco Moco.

Along with its simplicity, this Automatic Rice Cooker features a convenient body style. The lid comes with a streamlined handle and can be opened with the push of a button. The hinge on the lid allows for convenient serving, and when closed, the lid snaps tight. The rice cooker features a dew collector, which traps condensation that collects when the lid is opened.

As with all of our products, cleaning and maintenance are simple. The inner lid and dew collector, as well as the nonstick coated inner cooking pan, can be removed and washed with mild detergent and warm water.

The unit comes with a detachable power cord, and accessories including a rice measuring cup, spatula and spatula holder. And these accessories make preparing rice super easy!

Design Explained –
Our Half-Circle

Have you seen our half-circle?

It’s subtle. It’s small. It’s white. And it’s an ingenious feature that indicates whether the removable control plugs for our electric grills and griddles are inserted into the appliance properly.

While our rice cookers, water boilers and other electric products are controlled by onboard LCD panels and powered using power cords, our Gourmet Sizzler® electric griddles and indoor electric grills use a removable control plug that serves both functions: to provide power to the appliance and to manage the temperature setting. These high-powered control plugs conduct electricity efficiently to the appliances, allowing them to heat quickly at the temperature set using the control knob.

The control plugs are installed into the sides of the grills and griddles and “click” into place. On the release buttons located at the sides of the control plugs are white half-circles. And while they look cool, they actually serve as a safety feature. When the control plug is installed correctly into the appliance, the entire white area of the half-circle becomes visible. If it hasn’t clicked correctly into place, the half-circle is obscured.

Such a small smart design feature makes a big difference in safety. Zojirushi’s indoor grills and electric griddles are designed so they do not turn on unless all components are installed correctly. The drip tray not set properly? The control plug won’t go in. The control plug not inserted correctly or loose? Power won’t turn on. This way, no one gets burned or hurt by a heated, but improperly setup appliance.
