Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a high frequency heating device having a handling display.

[0002] It is related to.

[0003]

[Prior art]

 The high-frequency heating devices are roughly classified into two types: a single-function type microwave oven that heats food only with microwaves, and a multi-function type that has a heater heat source in addition to microwaves (hereinafter referred to as an oven range). There is. And in recent years, the percentage of users who purchase oven range has become even higher. This is because microwave ovens have become more automated, and grilled fish and cakes can now be cooked simply by pressing a switch button, and the convenience has been greatly recognized, and the products have been compacted. The reason for this is that it is no longer necessary to choose the storage location.

Depending on the cooking menu, the microwave oven may be heated only with microwaves, may be heated only with a heater, or may be heated with both a microwave and a heater. For automatic cooking, the user can simply look at the attached cooking book, make preparations, and then press the switch button. After that, the sensor inside the machine and the microcomputer on the operation board work to make microwaves or heaters available. Is operated optimally and the food is heated by automatically controlling the heating temperature and time.

As described above, the operation has been simplified, the functions have been increased, and the convenience has been improved. However, when the features and functions of the product increase, the product is sold without being explained to the user. become. For this reason, some products have a POP sticker (announcement at the time of purchase) attached to the front of the product that expresses the features and functions of the product.

Further, as the one using the door glass surface, a colored portion is formed by blank printing an appropriate pattern on the end portion of the surface of the door glass, and a thermochromic material that discolors at high temperature is applied to this blank portion. , Which displays a danger at a high temperature (for example, Japanese Utility Model Publication No. Sho 64-12109), or which displays a temperature at a high temperature by coating a transparent plate fitted in a peep window with a thermopaint (for example, Japanese Utility Model Publication 59). -12904).

[0007]

[Problems to be solved by the device]

 The POP sticker affixed to the front of the product will be peeled off from the product and discarded immediately after the user purchases it. This is because the center part of the front door of the high-frequency heating device is a finder, so if a POP sticker is attached to this part, you cannot see the food put in the heating chamber during cooking. This is because the temperature of the machine body rises during heating and the POP seal made of film is deformed by heat. This is also because the POP sticker has a sentence such as "Please remove it after purchase".

In addition, the use of the periphery of the surface of the door glass is to display the danger at the center of the surface of the door glass because it uses the property that the color changes when the temperature becomes high. It was not used because it would obstruct the viewfinder function when expressing features and functions.

[0009]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and a display composed of characters and illustrations explaining the features and functions of the product is displayed in the center of the surface of the door glass reversibly from colored to colorless at a constant temperature. It was printed using a thermochromic ink that changes color.

[0010]

[Action]

 With the above-mentioned configuration, the features and functions of the product are displayed on the front of the main unit when it is on display at a store or when it is not heated, while when the temperature rises to a certain level during cooking and heating, the center of the door glass surface is displayed. These indications disappear, and it becomes possible to observe the adjustment status of the heated object inside the main body from the viewfinder.

[0011]

【Example】

 FIG. 1 is a front view of a high-frequency heating apparatus according to an embodiment of the present invention. In the figure, a constant temperature (this embodiment is used) is set at a central portion (door finder portion) of a door glass surface 2 provided in front of a main body 1. In the example, a thermochromic ink that reversibly changes from colored to colorless at about 50 ° C) is used to print the display 3 composed of characters 3a and illustrations 3b expressing the features and functions of the product.

The door glass surface 2 is a POP (public notice at the time of purchase) when the product body 1 is displayed in a store, and also when the product 3 is not heated in a kitchen or the like, the display 3 is similarly colored to show the product on the front surface of the product 1. Display the features and functions of. On the other hand, when the door glass surface 2 is heated to 50 ° C. or more during heating and cooking, the display 3 becomes colorless, and the cooking status of the object to be heated in the heating chamber of the main body 1 can be observed from the finder section.

If the contents of the display 3 are valid for the user, the usage of the product and the notice may be printed. Depending on the application, two or more types of thermochromic and thermochromic inks may be used. For example, in addition to the printing described above, printing using an ink that is colorless below a certain temperature and develops color at high temperatures may be added to the main body 1 or door during cooking. When the temperature of the glass surface 2 exceeds a predetermined temperature (for example, 120 ° C.), another effect such as displaying a danger can be measured.

[0014]

[Effect of device]

 As described above, according to the present invention, the predetermined display is printed on the center of the surface of the door glass by using the thermo-reversible thermo-coloring ink, so that the POP display can be performed without using the POP sticker, and the POP display is disturbed during cooking. This has the effect of making it easier to observe the adjustment status of the heated object from the viewfinder section.
