Problems solved by technology

However, if the above method is used to increase the amount of steam, it is found that the problem of microwave leakage occasionally occurs
Various experiments conducted in order to find out this reason have shown that in the process of emitting microwaves, if there is no water in the evaporating dish and water is added to the evaporating dish, microwave leakage will easily occur.

Embodiment approach 1

[0024] Such as figure 1 As shown, the high-frequency electromagnetic wave cooking appliance 10 with a steam generating function according to Embodiment 1 is provided with a water supply device 20 for supplying water to the evaporating pan 109 . The water supply device 20 can be arranged in the side wall 103a of the heating chamber 103, but it is not limited to this position. It is best to be arranged not far from the evaporating dish 109 and away from the high-frequency electromagnetic wave generating device 104 such as a magnetron. superior.

[0025] As shown in Figure 2, the water supply device 20 is provided with: a water tank 21 for water storage, a water supply control device 22 (hereinafter referred to as "water pump" for short) composed of a water pump that absorbs water in the water tank 21 and supplies it to a water supply pipe 23, etc. 22 "), and the water supply pipe 23 that supplies water to the evaporating dish 109. The water supply pipe 23 passes through the s...

Embodiment approach 2

[0031] Figure 4 It is a schematic sectional view of Embodiment 2. In Embodiment 2, a structure in which electromagnetic wave leakage does not occur even if the water supply pipe 23 is filled with water is adopted. Specifically, the size of the water supply pipe 23 protruding from the heating chamber wall 103a into the heating chamber is set to be less than or equal to 25 mm. .

[0032] Specifically, a large number of experimental results show that although the high-frequency electromagnetic waves in the heating chamber are continuously reflected by the heating chamber wall 103a, the output power of the high-frequency electromagnetic waves reflected by the heating chamber wall 103a is the maximum at 1 / 4 wavelength; if the water supply pipe The front end of 23 or the water flow front end flowing out from the water supply pipe 23 is located at the position of this 1 / 4 wavelength, then the high-frequency electromagnetic wave is easy to leak through the water. For this reason, i...

Embodiment approach 3

[0035] Next, Embodiment 3 in which electromagnetic waves do not leak even when the water supply pipe 23 is filled with water will be described.

[0036] Fig. 5 is a schematic diagram of the composition of a water supply device for supplying water to a water supply pipe, Figure 6 (A) is a perspective view of a water supply pipe, Figure 6 (B) is an exploded perspective view of a water supply pipe, Figure 6 (C) is from Figure 6 (A) The end view seen from the C direction. Fig. 7 is a sectional view of the water supply pipe in an installed state. In addition, only the same code|symbol is attached|subjected to the same part as the said Embodiment 1 and the prior art here, and the repeated description is abbreviate|omitted.

[0037] Such as Figure 6 As shown in (B), the water supply pipe 25 is composed of an inner water supply pipe 25a located inside the heating chamber 103, and an outer water supply pipe 25b located outside the heating chamber. An installation part 26 is ...

Abstract

The invention provides a high frequency electromagnetic wave cooking apparatus with steam generating function without high frequency electromagnetic wave leakage when using the steam and high frequency electromagnetic wave to cook, including an evaporating utensil (109) arranged in a heating chamber (103), a water supply pipe (23) that supplies water to the evaporating utensil by penetrating a heating chamber wall, a water supply control device (22) that controls water supply to the evaporating utensil, a high frequency electromagnetic wave generating device (104) that provides high frequency electromagnetic wave to the heating chamber, a control unit (40) that controls the water supply control device and the high frequency electromagnetic wave generating device. The control unit stops operating the high frequency electromagnetic wave generating device when using the water supply control device to supply water to the evaporating utensil. Therefore, if the water supply penetrating the heating chamber wall is filled with water when supplying water to the evaporating utensil, the high frequency electromagnetic wave leakage does not occur because there is no high frequency electromagnetic wave , which generates a lot of steam and prevents the electromagnetic wave from leakage.

Description

technical field [0001] The invention relates to a high-frequency electromagnetic wave cooking appliance which uses steam to heat an object to be heated and has a steam generating function. Background technique [0002] In existing high-frequency electromagnetic wave cooking utensils, some also adopt steam to cook (an example wherein can refer to Japanese Patent 3,473,908. [0003] Figure 10 shows the high-frequency electromagnetic wave cooking appliance 100 with steam generating function in the above-mentioned reference. The high-frequency electromagnetic wave cooking appliance 100 uses at least one of high-frequency electromagnetic waves and steam to heat the object to be heated, and has a rectangular box-shaped body 101 with an opening on the front surface. Door 102. A heating chamber 103 is provided inside the machine body 101 , and a magnetron 104 for radiating high-frequency electromagnetic waves and a rotating antenna 105 are arranged below the heating chamber 103 ,...
