Abstract

PURPOSE:To prevent the steaming-up of a scale part due to steam produced from a food, by a method wherein a temperature pointer, moving in linkage with a temperature regulator, is adapted to be moved between a pair of elastic materials which are positioned facing each other and brought into contact with each other. CONSTITUTION:A temperature pointer 11 is positioned between a transparent window 13 of a control panel and a temperature scale table 10, and the base of the temperature pointer 11 is adapted to be moved between an elastic material 14, stuck to the transparent window 13, and an elastic material 15, stuck to the temperature scale table 10, in a condition that the pointer is brought into contact with the two elastic materials 14 and 15. This prevents steam, produced from a food, from invading into a space in which the temperature pointer 11 moves, and enables steaming up of the transparent window.

Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to prevent a transparent window of a temperature adjustment scale from becoming cloudy due to steam generated when heating food. The goal is to improve product quality. In conventional heating cookers,
In order to adjust the temperature of the heating chamber to the optimum temperature for the food to be cooked or the menu, it is common to have a temperature control device to control the output of the heating element, and the temperature control device should be placed near the temperature control device. There is a temperature scale in which a temperature indicator needle moves in conjunction with a temperature control device. This temperature indicator needle is located between the transparent window of the operation panel and the temperature scale, and its base slides on the side wall surface of the temperature scale. The temperature control device is configured to be interlocked with a plurality of pulleys, strings, and springs.

By the way, when food is placed in a heating chamber and cooked, as the food is heated by the heating device, water contained in the food turns into steam and comes out through various openings in the heating chamber. Some of this also got into the temperature scale part of the operation panel, which was explained earlier, and the transparent window sometimes became cloudy. In such a state, not only the temperature scale becomes difficult to see, but also the marketability of the product is reduced. In particular, this clouding phenomenon becomes more pronounced as the temperature gets lower, and even with convection ovens that have heaters built in above and below the heating chamber, ovens that circulate hot air inside the heating chamber are better than ovens that circulate hot air outside the heating chamber. The amount of leakage will increase.

This is thought to be because air pressurized by the hot air circulation fan flows inside the heating chamber and exits easily from the opening.

The present invention solves the above-mentioned problem that the temperature scale of the conventional operation/tunnel is cloudy, and also increases the commercial value.

The present invention will be explained below using an example in which the present invention is implemented in a high-frequency heating device with a heater.

The cooking device main body 1 has a heating chamber for heating food, and is equipped with a high-frequency heating device and a power source for generating high-frequency waves in the heating chamber for heating food using high-frequency waves, and also for raising the temperature of the heating chamber to a high temperature. It is equipped with a heater for heating food. A door 2 is attached to the opening surface of the heating chamber so that it can be opened and closed freely.
An operation panel 3 is provided on the front of the main body 1. This operation panel 3 has a cooking selection button 4 for selecting and switching between high-frequency power ρ heat and heater heating. heating by.

Select heating using an oven heater. 5 and 6 are timers having two types of time limits, each of which is a circuit that operates individually or in conjunction with each other. 7 is the cooking start point, and upon operation of this button, the operation display button 8 lights up and heating of the food begins. A temperature control knob 9 is attached to the main shaft of the temperature control device and can adjust the temperature of the heating chamber.

The temperature sensing part of this temperature control device is installed near the heating chamber, and when the set temperature is reached, the temperature control device controls the power of the oven heater. The operation panel 3 has a temperature scale table 10 to display the temperature set in the heating chamber, and this temperature scale table includes a non-temperature scale 10a and a representative temperature scale 10a to indicate the temperature of the heating chamber. Food names 10b of typical oven dishes are listed. When the knob 9 of the temperature control device is operated, the indicator needle 11, which is linked to the main shaft of the temperature control device and slides on the wall surface of the temperature scale table 10, displays the temperature of the heating chamber. The interlocking mechanism between the indicator needle 11 and the temperature adjustment device is composed of a plurality of pulleys of different sizes, threads, and springs.

In the temperature scale table 1o of the present invention, the display position of the food name 10b for typical oven cooking is made to correspond to the heating temperature during oven cooking, and when setting the temperature, simply align the indicator needle with the food name. , you can set the temperature at which the food will be heated. The temperature indicator needle 11 is made of a metal wire, and its base is integrally formed with a sliding portion 12 made of resin by fitting and adhesive. This sliding portion moves along the side wall of the temperature scale 10 in conjunction with the temperature adjustment device. The temperature indicator needle 11 is located between the transparent window 13 of the operation panel 3 and the temperature scale table 10, and the base of the temperature indicator needle 11 is attached to the elastic body 14 attached to the transparent window 13 side and the temperature scale table 10 side. Moves between the elastic bodies 16 and the two elastic bodies 14.15
are always in contact with each other. The material of the elastic bodies 14 and 16 in the embodiment does not interfere with the operation of the temperature indicator needle 11, does not require heavy operating force for the temperature control knob 9, and is sufficient to prevent spiders from forming on the transparent window portion 13, which is the objective of the present invention. In the examples of the present invention, polyester-based polyurethane foam is used as a material with excellent wear resistance and heat resistance for the tray, but it is clear that other materials can be used as long as the above conditions are met. It is.

Further, an elastic material 16 is interposed between the outer circumferential line (right, left, lower side) of the temperature indicator needle 11 of the temperature scale table 10 other than the sliding side (in the case of the embodiment of the present invention, the upper side) and the operation panel 3. Particularly, the air on the inner surface of the transparent window portion 13 is completely isolated from the outside air. That is, even if steam leaks from the heating chamber, it does not reach the transparent window section 13''!, so the transparent window section 13 is not fogged.

As explained above, by sandwiching the temperature indicator needle between elastic materials and placing elastic materials on the other three sides of the temperature scale table, steam may enter the back side of the transparent window.
Since the product value is not reduced due to cloudy and difficult to see clouds or spiders, the quality and value of the product is increased and the effect brought about is very large.
