Description

[Detailed description of the invention] The purpose of this invention is to make the high-frequency heating device more convenient by providing a scale, and to make it easier to use, more reliable, and more economical by devising a mechanism for the scale. It is said that

Generally, the heating time of a high-frequency heating device is determined by the weight of the object to be heated. Therefore, when setting the heating time, it is necessary to know the weight. In addition, in the case of a composite product that incorporates a heater into a high-frequency heating device that has been put into practical use recently, when using the heater as an electric oven, it is important to accurately measure the weight of the food ingredients and mix them. This leads to better cooking results.

As described above, weight measurement is essential for high-frequency heating devices. However, the conventional method used a separate scale to measure weight. This was inconvenient because it was difficult to find a place to put the scale, and it took time and effort to find and take out the scale each time a measurement was to be made. In addition, some configurations in which a scale is incorporated into a high-frequency heating device have been devised, but the present invention aims to provide a more specific, easy-to-use, and practical configuration.

FIG. 1 is a perspective view showing the appearance of a high-frequency heating device according to the present invention.

In FIG. 1, a door 2 is provided on the front surface of a main body 1 so as to be openable and closable. There is also a panel 3 on the main body 1.
A heating time setting timer 4, a heating start button 5, and other operation parts are provided. The lower part of the main body 1 has a built-in weighing mechanism. 6 is a mounting plate for the object to be measured. On the panel 3 is a weight display section 7 of the scale mechanism.
has been established. 8 is the leg.

FIG. 2 is a partially cutaway perspective view showing the structure of the scale mechanism of the high-frequency heating device according to the present invention shown in FIG. 1.

In FIG. 2, a scale mechanism consisting of a metal fitting A10, a metal fitting B11, and four leaf springs 12 is fixed to a mounting plate 9 fixed inside the leg 8. Both ends of the leaf spring 12 are riveted to a metal fitting A10 and a metal fitting B11. The mounting plate 6 is fixed to the metal fitting B11 by an arm 13. The metal fitting B11 is further provided with a rack 14, which meshes with a pinion 16 fixed to a pointer 15 of a weight display section 7 provided on the panel.

According to such a configuration, since the metal fitting B11 is supported by four leaf springs 12, it moves vertically in parallel, and the object to be measured placed on the mounting plate 6 fixed to the metal fitting B11 moves in parallel. The leaf spring 12 bends in proportion to the weight, and the metal fitting B11 lowers. This state is shown by a two-dot chain line. When the metal fitting B11 is lowered,
The rack 14 also lowers, the pinion 16 meshing with it rotates, and the pointer 15 swings. Leaf spring 1
The weight can be measured by appropriately selecting the elasticity of item 2 and displaying a scale corresponding to the weight of the object on the weight display section 7.

According to the high-frequency heating device of the present invention, the weight can be easily measured before heating starts, and the heating time can be set easily and accurately, so heating can be performed without mistakes such as overheating. can. In addition, since the ingredients such as those to be heated can be properly and accurately mixed, the cooking results can be uniform and baked in good condition.

Compared to using another stand-alone scale, this scale is convenient because you don't have to worry about where to put it, and you don't have to waste time searching for it every time you want to take a measurement.

Further, according to the present invention, since the scale mechanism parts such as the metal fitting B11 supporting the mounting plate 6 are supported by the plate spring 12, the plate spring 12
However, it functions both as an elastic body for balance of the scale and as a support for parallel movement, resulting in a flat and compact structure, and a horizontally extending mechanism that takes up a relatively large space. On the other hand, since the space in the height direction can be shortened, the height of the legs 8 can be stored without being extremely high, and the space can be used effectively, so the whole can be made compact as a high-frequency heating device. Can be done. The other space on the legs can also be used as a storage for accessory parts, making the device even more convenient. By using the leaf spring 12, the shape is not only compact, but the structure is also extremely simple, can be constructed at low cost, and can be easily assembled, making it possible to construct it more efficiently.

According to the scale mechanism of the present invention, since the scale is installed at the bottom of the main body, even if the high-frequency heating device is placed at a relatively high position such as on top of a refrigerator, the object to be measured can be easily placed on it, and the center of gravity The stability is also high because it is low. Since the display section is provided in the main body, the movement of the placing tray can be easily transmitted to the display section, and the display section is also easy to see and easy to handle.

Furthermore, since the scale mechanism can be easily attached and detached by attaching and detaching the legs, it can be attached as an option, such as attaching it only to devices that require a scale. Furthermore, by changing the elasticity of the leaf springs, it becomes possible to select and equip scales with different measurement ranges as needed.

Providing the scale mechanism at the bottom of the main body prevents the area near the scale from becoming hot even in the case of a high-frequency heating device with a built-in heater, and is safe without the risk of burns during measurement. Since the elasticity of springs changes depending on temperature, errors occur when the temperature changes extremely, but this is not necessary and accurate measurements can be made at all times. Since the component parts do not require much heat resistance, they can be constructed from inexpensive materials and are economical. Since the display section is provided on the main body, you can check the timer and other functions at the same time, making it easy and convenient to operate.

Furthermore, if a control circuit connected to the display section is provided,
It is also possible to easily realize a configuration in which the heating time, timer, etc. are directly controlled by the display on the scale, and it is also possible to realize a more convenient high-frequency heating device.

As described above, according to the present invention, with a simple configuration,
The present invention provides a convenient, easy-to-use, and highly practical high-frequency heating device at a more economical cost.
