突出させたマグネトロンである。 In the figure, 1 is a heating chamber, 2 is a power supply port bored in one wall of the heating chamber, that is, the upper wall 1a, and the periphery of the power supply port projects outward from the heating chamber 1 and forms a step. The power supply port 2 is located slightly above the heating chamber upper wall 1a. Further, an insertion hole 3 is bored in a stepped portion on one side of the periphery of the power supply port 2. Reference numeral 4 denotes a protective cover mounted within the stepped portion so as to cover the power supply port 2 from inside the heating chamber 1, and the protective cover is made of a radio wave transparent material such as plastic. Further, one side of the protective cover 4 is inserted into the insertion hole 3, and is attached to the upper wall 1 with a clip pin 5.
It is fixed at a. Reference numeral 6 denotes a waveguide communicating with the heating chamber 1 through the power supply port 2, and the waveguide has a part of the upper wall 1a of the heating chamber as a bottom surface, and a part of the upper wall 1a of the heating chamber.
For example, they are fixed by spot welding without any gaps. 7 is a magnetron having an antenna portion 7a protruding into the waveguide 6.

ることとなる。 In such a device, since the power supply port 2 is covered by the protective cover 4, it is possible to prevent dust, water vapor, etc. from entering the waveguide 6. Further, since the protective cover 4 is fitted into the stepped portion, the fragile outer edge of the protective cover 4 is protected by the stepped portion from being touched by hands or the like when taking out or taking out food.

生原因となり加工上好ましくない。 However, the upper wall 1a of the heating chamber around the power supply port 2
is a stepped part that protrudes outward, so the third
As shown in the figure, the waveguide 6 must also have a step corresponding to the step. However, it is difficult to completely match the stepped portion of the heating chamber upper wall 1a and the waveguide 6 in this way, and when spot welding, the heating chamber upper wall 1a and the waveguide 6 are There is a risk that a gap may occur between the two, and radio waves may leak through the gap.
Furthermore, if the waveguide 6 is provided with a stepped portion, it may cause warping or twisting, which is unfavorable in terms of processing.
本考案は上記の問題に鑑みてなされたもので、
以下実施例に基づいて本考案を説明する。 This idea was created in view of the above problems.
The present invention will be explained below based on examples.

より完全に覆われている。 The difference between the device of this embodiment and the conventional device is that instead of the stepped portion of the conventional device, a power supply port 2 on the upper wall 1a of the heating chamber is provided.
By pressing the peripheral edge inward of the heating chamber 1, a seating portion is provided on the upper wall 1a. Further, in this embodiment, such a seat push part includes a first seat push part 8a extending perpendicularly to the extending direction of the waveguide 6 and along one side of the power supply port 2 on the magnetron 7 side; It consists of a second seat push part 8b that is not continuous with the seat push part and is provided along the other three sides. The first seat pusher 8
Similar to the conventional device, an insertion hole 9 is provided on the power supply port 2 side of a. Therefore, the protective cover 4 is
By partially inserting it into the insertion hole 3 and fixing it with the clip pin 5, the seat pressing part 8
It is attached to the inner surface of the heating chamber upper wall 1a from inside the heating chamber inside the area partitioned by a and 8b. Further, the first seat pressing portion 8a is completely covered by the waveguide 6.

が生じることもない。 Furthermore, in this embodiment, unlike the conventional device, the heating chamber upper wall 1a does not protrude outward, so there is no need to provide a stepped portion in the waveguide 6, and therefore the heating chamber upper wall 1a and the waveguide 6 are It can be fixed without any gaps by spot welding. Further, the waveguide 6 is not warped or twisted.

を防止することが好ましい。 In this embodiment, a part of one side of the protective cover 4 is inserted into the insertion hole 3 and fixed to the inner surface of the upper wall 1a, but it may also be fixed simply with a clip pin. In addition, the first and second seat pushers 8 that are not continuous with the seat pushers 8
Although the seat push portions 8a and 8b are configured in this embodiment, the seat push portions 8a and 8b may be configured continuously. In this case, it is preferable to cover the entire seat push part with a waveguide to prevent radio waves from leaking through the seat push part.
