[0027] The following will use the terms commonly used by those skilled in the art to convey the essence of their work to other technical personnel in the art to describe the utility model concepts of the present disclosure. However, these utility model concepts can be embodied in many different forms and should not be considered as limited to the embodiments described herein.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] In order to solve the problem that the parts of the vehicle-mounted microwave oven in the prior art are poorly arranged in a compact manner, this embodiment provides a vehicle-mounted microwave oven, as shown in the attached Figure 1-6As shown, the vehicle-mounted microwave oven includes a cavity top plate 1, a U-shaped plate 10, and a filter bracket 11. The filter bracket 11 is arranged on the upper surface of the cavity top plate 1. A wave-transmitting plate 9 is arranged on the lower side of the cavity top plate 1. The filter bracket 11, the cavity top plate 1, and the side walls of the U-shaped plate 10 are connected. The wave-transmitting plate 9 is connected to the cavity top plate 1 by fasteners, and is connected to the filter bracket 11 by snap-fitting. It should be noted that the side walls of the filter bracket 11, the cavity top plate 1, and the U-shaped plate 10 can be connected by two adjacent ones, or the three can be connected at the same time. The present application preferably configures the filter bracket 11, the cavity top plate 1, and the side walls of the U-shaped plate 10 to be connected by the same fasteners, which can be regarded as the fasteners connecting the three together at the same time.

[0031] Therefore, the present application arranges the filter bracket 11 and the wave-transmitting plate 9 together on the cavity top plate 1 and performs specific connection and fixation. On the one hand, the relevant components in the vehicle-mounted microwave oven are arranged more compactly, thereby improving the space utilization rate of the vehicle-mounted microwave oven itself. On the other hand, it is beneficial to improve the connection strength of the relevant components to avoid the separation or falling off of the components due to vehicle bumps or vibrations.

[0032] The cavity top plate 1 and the two side walls of the U-shaped plate 10 are connected to form the inner pot structure of the microwave oven. Correspondingly, the cavity top plate 1, the U-shaped plate 10 and the shell rear plate (not shown) together form the inner cavity 6 of the microwave oven.

[0033] The cavity top plate 1 is provided with an assembly area 12, and the wave-transmitting plate 9 is connected to the assembly area 12 by fastener connection; for the connection between the wave-transmitting plate 9 and the cavity top plate 1, a screw column 18 is provided on the outer edge of the wave-transmitting plate 9, and the screw column 18 passes through the assembly area 12 and is connected to the assembly area 12 by fasteners. Above the assembly area 12, a washer 8 is sleeved on the outer edge of the screw column 18, and the wave-transmitting plate 9 is fixedly connected to the cavity top plate 1 by screws.

[0034] Filter brackets 11 are provided on both sides of the assembly area 12, and any filter bracket 11 can be provided with a filter device 4, so as to improve the compatibility of related parts in the production and assembly process, so that one part can meet the assembly requirements of different models, and the cavity top plate 1 can be correctly assembled with the U-shaped plate 10 without orientation in the left and right directions, which is conducive to reducing the difficulty of assembly. At the same time, the wave-transmitting plate 9 can be connected to the filter brackets 11 on both sides respectively, which is also conducive to improving the assembly stability of the wave-transmitting plate 9 and other parts, so as to avoid the separation or falling off of parts due to vehicle bumps or vibrations.

[0035] The filter bracket 11 has an assembly column 21, and the filter device 4 is connected to the assembly column 21 by a fastener connection. As a preferred embodiment of the present application, the filter device 4 is connected to the filter bracket 11 away from the side of the electrical cavity 7 of the vehicle-mounted microwave oven to minimize the high temperature interference and EMC interference of the electrical cavity 7 on the filter device 4. At the same time, it is also convenient to directly connect the filter device 4 to the power line on one side of the vehicle-mounted microwave oven to filter the current.

[0036] Among them, the two filter brackets 11 located on both sides of the assembly area 12 correspond to the two side walls of the U-shaped plate 10 one by one, so that the filter bracket 11 can be located above the side wall of the U-shaped plate 10 in spatial orientation; accordingly, the filter bracket 11, the cavity top plate 1, and the side wall of the U-shaped plate 10 are arranged in sequence from top to bottom and fixedly connected by fasteners. Specifically, the filter bracket 11 is provided with a fixing hole 25, and the cavity top plate 1 and the side wall of the U-shaped plate 10 are both provided with corresponding assembly holes, and the three hole structures are aligned and fixed by the same screw.

[0037] Regarding the connection between the wave-transmitting plate 9 and the filter bracket 11, a card interface 24 is provided on one side of the filter bracket 11 close to the assembly area 12, and a card connection column 19 is provided on the outer edge of the wave-transmitting plate 9 close to the filter bracket 11. The card connection column 19 penetrates the assembly area 12 and is carded with the card interface 24. Since the filter brackets 11 are provided on both sides of the assembly area 12, the wave-transmitting plate 9 can be carded with two filter brackets 11 at the same time, thereby improving the assembly reliability of the wave-transmitting plate 9. Among them, card slots 20 are provided on both sides of the card connection column 19, so that the card slots 20 are carded with the card interface 24.

[0038] In addition, the wave-transmitting plate 9 is also connected to the lower surface of the assembly area 12 in an adhesive manner, and the wave-transmitting plate 9 can be made of PP material.

[0039] The vehicle-mounted microwave oven includes a magnetron 5 and a waveguide box 2. The magnetron 5 is arranged in the electrical cavity 7 of the vehicle-mounted microwave oven. One side of the waveguide box 2 is connected to the magnetron 5, and the other side extends to above the assembly area 12, so that the microwave outlet of the waveguide box 2 is connected to the inner cavity 6 of the vehicle-mounted microwave oven.

[0040] The microwave outlet of the waveguide box 2 is provided with a driving device 3 and a stirring plate 14, the driving device 3 is connected to the waveguide box 2, the assembly area 12 has an upper convex portion 13, a chamber 17 is formed between the wave-transmitting plate 9 and the upper convex portion 13, the stirring plate 14 is arranged in the chamber 17, and the output shaft of the driving device 3 passes through the upper convex portion 13 and is connected to the stirring plate 14 to drive the stirring plate 14 to rotate. Therefore, the present application not only centrally arranges the filter bracket 11 and the wave-transmitting plate 9 at the cavity top plate 1, but also centrally arranges the waveguide box 2 and the stirring-related devices at the cavity top plate 1 on this basis, further improving the compactness of the arrangement of the relevant components in the vehicle-mounted microwave oven, which is conducive to improving the space utilization rate of the vehicle-mounted microwave oven itself.

[0041] Since the assembly area 12 is provided with an upper convex portion 13, a flange 22 is provided on the side of the filter bracket 11 close to the assembly area 12, and a constriction 23 is provided on the flange 22, and the constriction 23 is connected to the card interface 24. A plurality of constrictions 23 and card interfaces 24 may also be provided, and the two correspond to each other. On the one hand, the filter bracket 11 avoids the upper convex portion 13 through the flange 22 to avoid spatial interference, and also enables the filter bracket 11 to extend a greater distance toward the assembly area 12, which is conducive to fully meeting the space requirements for the assembly of the filter device 4. On the other hand, the constriction 23 provided on the flange 22 enables the clamping column 19 to be more smoothly clamped into the card interface 24 when the filter bracket 11 is clamped with the wave-transmitting plate 9, which facilitates the clamping assembly between the two and reduces the difficulty of the assembly operation. It should be noted that in the direction gradually approaching the card interface 24, the opening size of the constriction 23 gradually decreases, forming a gradually shrinking opening until it is smoothly connected with the card interface 24.

[0042] At the same time, the vehicle-mounted microwave oven includes a front panel 15, and the front panel 15 is provided with an air outlet 16 corresponding to the filter bracket 11, so that the heat dissipation airflow in the vehicle-mounted microwave oven can flow from the air outlet 16 to the outside of the vehicle-mounted microwave oven when passing near the filter bracket 11, and take away the heat of the filter device 4, thereby realizing the heat dissipation of the filter device 4.

[0043] Specifically, due to the upper convex portion provided in the assembly area, some areas of the cavity top plate 1 are high and some areas are low (such as high in the center and low around as shown in the figure), so that a certain cavity is formed between the cavity top plate 1 and the upper top plate of the shell (not shown), which is recorded as a gas flow channel. The gas flow channel is connected to the electrical cavity 7 and the air outlet 16 respectively, and the filter bracket 11 located on both sides of the assembly area 12 is also located in the gas flow channel. At the same time, the filter device 4 is connected to the filter bracket 11 on the side away from the electrical cavity 7 of the vehicle-mounted microwave oven. On the one hand, the heat dissipation airflow in the electrical cavity 7 can flow into the gas flow channel and flow to the filter device 4 to dissipate heat. On the other hand, since the filter device 4 is a certain distance away from the electrical cavity 7, it is beneficial to reduce the airflow velocity to a certain extent, and can effectively prevent the airflow in the electrical cavity 7 from directly impacting the filter device 4. Preferably, the assembly area 12 is located in the central area of ​​the cavity top plate 1, and an upper protrusion 13 is provided in the central area of ​​the assembly area 12, which is not only conducive to optimizing the spatial layout of related components in the vehicle-mounted microwave oven, but also allows most of the gas flow channels to surround the outer side of the upper protrusion, so that the airflow can be distributed and flow more evenly between the cavity top plate 1 and the upper top plate of the shell, which is conducive to more uniform heat dissipation of the components between the cavity top plate 1 and the upper top plate of the shell.

[0044] In the utility model, any vehicle-mounted microwave oven may include the relevant structures and assembly relationships provided in this embodiment; on this basis, the vehicle-mounted microwave oven also includes conventional components of a microwave oven including a shell, a control panel, a door body and other structures. Since they are all prior art, they will not be elaborated here.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
