TECHNICAL FIELD

[0001] The utility model relates to the field of vehicle microwave oven, especially to a heat dissipation structure of embedded vehicle microwave oven. BACKGROUND

[0002] The embedded vehicle microwave oven is different from the domestic microwave oven, and the installation is directly embedded into the installation hole position arranged in the vehicle. When the magnetron of the microwave oven generates microwaves to work, a large amount of heat is generated. In order to ensure the heat dissipation of the work, the inner cavity of the microwave oven needs to be cooled. The conventional domestic microwave oven is provided with an air inlet and an air outlet on the left and right sides of the microwave oven to realize the convection cooling.

[0003] In the embedded microwave oven, this kind of heat dissipation structure is difficult to complete the air convection work in the inner cavity. In order to ensure that the air inlet and air outlet on both sides have a heat dissipation effect, it is necessary to ensure that the vehicle microwave oven has a gap between the left and right side walls after being embedded. This will increase the installation position required and waste the space in the vehicle. In addition, the small gap is also difficult to dissipate hot air, and the heat dissipation effect is still not ideal. SUMMARY

[0004] In order to make up for the shortcomings of the prior art, the purpose of the utility model is to provide a heat dissipation structure of embedded vehicle microwave oven, which solves the problem that the heat dissipation structure of the microwave oven with air inlet and air outlet on both sides is not ideal when used in the embedded microwave oven.

DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments.

[0020] Please refer to Figures 1 to 5 The embodiment provides a heat dissipation structure of an embedded vehicle-mounted microwave oven, which comprises a microwave oven 1, a microwave source 2 fixed in an inner cavity of the microwave oven 1, an air inlet 3 and an air outlet 4 arranged on the left and right sides of a front side plate 101 of the microwave oven 1 respectively, and a filter screen 5 fixed on the inner wall of the air inlet 3. The air inlet 3 and the air outlet 4 are arranged on the front side plate 101 of the microwave oven 1, instead of the traditional heat dissipation structure arranged on the left and right sides of the microwave oven 1, so that no gap needs to be reserved between the left and right sides of the microwave oven 1 and the inner wall of the installation position during installation, and the installation position can be directly designed as the size of the microwave oven 1 directly inserted, without wasting the space in the vehicle and ensuring that the microwave source 2 can be well cooled, and the filter screen 5 can ensure that the gas entering the inner cavity of the microwave oven 1 is filtered to avoid impurities from entering.

[0021] The first section air guide pipe 6, the second section air guide pipe 7 and the third section air guide pipe 8 are sequentially fixed in the inner cavity of the microwave oven 1 from front to back, the air inlet fan 9 is fixed on the inner wall of the first section air guide pipe 6, the air inlet end of the first section air guide pipe 6 is fixedly connected with the inner cavity of the microwave oven 1, and the air inlet end of the first section air guide pipe 6 is opposite to and communicates with the air inlet 3, during heat dissipation, the air inlet fan 9 works to suck external air into the first section air guide pipe 6 through the filter screen 5, and then the external air enters the third section air guide pipe 8 through the second section air guide pipe 7.

[0022] The second section air guide pipe 7 is gradually reduced in size from front to back, so that the airflow is accelerated, and the bottom surface of the third section air guide pipe 8 is symmetrically fixed with two supporting blocks 10, the bottom of the supporting block 10 is fixed with the inner cavity of the microwave oven 1, and the third section air guide pipe 8 is effectively supported by the supporting block 10, so that the vehicle-mounted use is adapted and the stability of the third section air guide pipe 8 is ensured.

[0023] The inner cavity of the third section air guide pipe 8 is divided into two independent air passages 12 by the partition plate 11 fixed on the inner wall of the air inlet end of the third section air guide pipe 8, two air outlets 13 are symmetrically arranged at the two ends of the top surface of the third section air guide pipe 8, the ends of the two air passages 12 are respectively connected with the two air outlets 13, the two air outlets 13 respectively face the two sides of the microwave source 2, and the horizontal plate and the vertical plate of the partition plate 11 are arranged in an arc shape at the connection position, so that when external air enters the third section air guide pipe 8, the external air is divided into two airflows by the partition plate 11 and reaches the two air outlets 13 through the two air passages 12, and then blows to the two sides of the microwave source 2.

[0024] On the outer wall of the microwave source 2, which faces the two air outlets 13, there are heat dissipation aluminum fins 14 at equal intervals. The gap between two adjacent heat dissipation aluminum fins 14 is directly opposite the air outlet 13. Cold air blows towards the heat dissipation aluminum fins 14, accelerating the loss of heat from the heat dissipation aluminum fins 14. Then, hot air is discharged through the exhaust port 4, realizing the heat dissipation of the microwave oven 1. Compared with traditional technology, it ensures good heat dissipation without increasing the installation space required, making it more suitable for in-vehicle embedded use. In addition, the air outlets 13 on both sides are directly opposite the two sides of the microwave source 2, so that the microwave source 2 is cooled from both sides, greatly improving the heat dissipation effect.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
