Description

Technical Field

[0001] This utility model relates to the field of air duct structure for vehicle microwave ovens, and more particularly to an air inlet and outlet structure for an embedded vehicle microwave oven. Background Technology

[0002] Traditional car microwave ovens are typically embedded in pre-designed recesses within the vehicle to secure the unit. However, their heat dissipation design has significant flaws: the cooling ducts on the sides or back of the microwave oven rely on a large ventilation gap between the recess and the appliance, resulting in a recess size far exceeding the microwave oven's dimensions. This design not only occupies excessive interior space, leading to low space utilization, but also significantly reduces heat dissipation efficiency due to the semi-enclosed structure of the recess restricting airflow. Furthermore, the microwave oven cannot be fully embedded in the recess during installation, making it susceptible to displacement and collisions due to vehicle vibrations, further impacting safety and stability. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an air intake and exhaust structure for an embedded vehicle microwave oven, which solves the problems of existing vehicle microwave ovens having poor heat dissipation duct design, resulting in excessive space occupation, poor heat dissipation efficiency, and unstable installation.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] An air inlet and outlet structure for an embedded vehicle microwave oven includes a housing. A heating cavity is provided on one side of the housing, and a microwave source mounting cavity is provided on the other side. An air inlet and an air outlet are provided on the panel of the housing from top to bottom. Both the air inlet and the air outlet are circular, and the diameter of the air inlet is smaller than the diameter of the air outlet. Both the air inlet and the air outlet are connected to the microwave source mounting cavity, and the air inlet is directly facing the microwave source inside the microwave source mounting cavity.

[0006] The outer wall of the panel is fixed with a cover. An air inlet cavity is formed at the upper end of the inner wall of the cover, which is connected to the air inlet. An air outlet cavity is formed at the lower end of the inner wall of the cover, which is connected to the air outlet. The air outlet cavity and the air inlet cavity are set independently. An air inlet groove and an air outlet groove are formed on the side wall of the cover, which are connected to the air inlet cavity and the air outlet cavity, respectively.

[0007] Preferably, a partition is formed in the middle of the inner wall of the cover, which divides the inner cavity of the cover into an air inlet cavity and an air outlet cavity distributed vertically. The inner side of the partition is flush with the inner side of the cover. Multiple air inlets are arranged at equal intervals from top to bottom, and multiple sets of air inlet slots are arranged. Each set of multiple air inlet slots is arranged at equal intervals. The multiple sets of air inlet slots are respectively arranged on the front, left, right and top of the upper end of the cover.

[0008] Preferably, the bottom of the cover is sloped, and multiple air outlet slots are provided. The multiple air outlet slots are arranged side by side on the sloped surface, and the height of the air outlet is higher than the height of the upper edge of the sloped surface. A touch screen mounting position is formed at the upper front side of the cover, and the height of the touch screen mounting position is higher than the height of the air inlet slot on the front side of the cover.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. This utility model arranges both the air inlet and the air outlet on the front panel of the housing. The recessed installation position in the vehicle that is compatible with this type of microwave oven does not need to be set with a large amount of redundant space. The microwave oven with this heat dissipation air inlet and outlet structure can be directly embedded in the recessed cavity in the vehicle, avoiding space waste and making the installation more stable. Moreover, compared with traditional technology, the design of the front air outlet is more conducive to the dissipation of heat after vehicle installation, and the heat dissipation effect is greatly improved.

[0011] 2. The design of the cover and its inclined surface ensures that the hot air is discharged downwards, which is opposite to the direction of the cold air intake, thus preventing the hot air that has just been discharged from being mixed into the microwave source installation cavity and ensuring the heat dissipation effect.

[0012] 3. The sloping design of the cover of this utility model takes into account the use of microwave ovens installed close to the ground, so as to avoid the air outlet being blocked. In addition, the height of the air inlet is higher than the height of the air outlet, which can also prevent the ground dust from being sucked into the casing when installed close to the ground.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 This embodiment provides an air intake and exhaust structure for an embedded vehicle microwave oven, including a housing 1. A heating cavity 101 is provided on one side of the housing 1, and a microwave source mounting cavity 102 is provided on the other side. The heating cavity 101 is the food placement position. When food is placed in the heating cavity 101, the microwave source 4 in the microwave source mounting cavity 102 works to heat the food.

[0020] The panel 103 of the housing 1 has three air inlets 2 and one air outlet 3 arranged from top to bottom. The three air inlets 2 are equally spaced. Both the air inlets 2 and the air outlet 3 are circular. Since there are multiple air inlets 2, the diameter of the air outlet 3 is larger than the diameter of the air inlets 2 in order to meet the air volume requirements. Both the air inlets 2 and the air outlet 3 are connected to the microwave source mounting cavity 102. The air inlets 2 are directly opposite the microwave source 4 inside the microwave source mounting cavity 102.

[0021] When assembling the microwave oven, an intake fan is fixed on the inner side of the panel 103, directly opposite the air inlet 2. The intake fan is not shown in the figure. A volute fan 5 is fixed on the outer side of the panel 103, directly opposite the air outlet 3. The intake fan and the volute fan 5 operate simultaneously, drawing in cool air from the outside and blowing it toward the microwave source 4 for heat dissipation. The volute fan 5 draws in hot air from the microwave source mounting cavity 102 and discharges it, achieving air circulation and convection to dissipate heat from the microwave source 4.

[0022] Both the air inlet 2 and the air outlet 3 are located on the front panel 103 of the housing 1, allowing the microwave oven to be directly embedded into the vehicle's recessed cavity without the need for extra space. This reduces the size of the cavity to improve the utilization of interior space, and optimizes the heat dissipation path through the design of the front air outlet 3. After installation, the microwave oven fits tightly into the cavity, eliminating the risk of displacement during driving, while also significantly improving heat dissipation efficiency compared to traditional structures.

[0023] A cover 6 is fixed to the outer wall of the panel 103. The inner cavity of the cover 6 is divided into an air inlet cavity and an air outlet cavity arranged vertically by a partition 602 formed in the middle of the inner wall of the cover 6. The inner side of the partition 602 is flush with the inner side of the cover 6, so that the air inlet cavity and the air outlet cavity can be completely isolated after the cover 6 is attached and fixed to the panel 103. The air inlet cavity is connected to the air inlet 2, and the air outlet cavity is connected to the air outlet 3, ensuring that the air inlet and outlet have their own paths and ensuring air exchange efficiency.

[0024] A set of air inlet slots 7 are provided on the front, left, right and top sides of the upper part of the cover 6. Multiple air inlet slots 7 are arranged at equal intervals in each set. The air inlet slots 7 are connected to the air inlet cavity. A touch screen mounting position 8 is formed at the upper front of the cover 6. The height of the touch screen mounting position 8 is higher than the height of the air inlet slots 7 on the front of the cover 6. Multiple air inlets ensure the air volume. The cold air outside enters the air inlet cavity through the air inlet slots 7 under the suction of the air intake fan, and then enters the microwave source mounting cavity 102 for heat dissipation through the air inlet 2.

[0025] The bottom of the cover 6 is set with a slope 601, on which multiple air outlet slots 9 are formed side by side. The air outlet slots 9 are connected to the air outlet cavity. The height of the air outlet 3 is higher than the height of the upper edge of the slope 601. The volute fan 5 is covered in the air outlet cavity, and the air outlet end of the volute fan 5 is directly facing the slope 601. In this way, the hot air in the microwave source mounting cavity 102 is drawn and discharged from the air outlet slots 9. This structural design makes the air outlet direction downward and staggered from the upper horizontal air inlet direction, avoiding the mixing of hot and cold air and ensuring the heat dissipation effect.

[0026] Furthermore, the design with the air intake at the top and the air outlet at the bottom is suitable for microwave ovens installed close to the ground inside a vehicle, preventing dust from being attracted into the microwave source installation cavity 102. The design of the sloping surface 601 is also suitable for microwave ovens installed close to the ground, ensuring that the air outlet duct 9 is not blocked by the ground and that the front of the air outlet duct 9 has a relatively spacious area for hot air to be discharged, ensuring that heat can be dissipated well.

[0027] 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.
