Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to a three-layer heat dissipation system structure of an oven. Background Art

[0002] As ovens become more commonplace, their design and functionality are constantly being optimized. Due to their high operating temperatures, ovens require heat dissipation to ensure proper functioning of their electrical components. Currently, ovens generally utilize an air-cooled heat dissipation system, consisting of an oven housing and a cooling fan. The housing consists of an inner liner, a door, and an outer shell. The outer shell is positioned outside the inner liner, forming a sandwich between the two. The outer shell is provided with air inlets, and one side of the inner liner is opened. The door covers the opening. The cooling fan drives airflow within the oven, dissipating heat.

[0003] Although this heat dissipation system can meet the heat dissipation needs of the oven to a certain extent, it is not specially optimized for the heat dissipation of the door panel. After the baking operation is completed, the temperature of the door panel is often very high. If it is not effectively cooled, it will not only affect the service life of the door panel, but also reduce the safety of operation.

[0004] Therefore, in order to further improve the applicability of existing ovens, we propose a three-layer heat dissipation system structure for ovens. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-6This is an embodiment of the present utility model, which discloses a three-layer heat dissipation system structure of an oven. Specifically, the heat dissipation system structure includes a box body 1 having an air inlet duct 11 and an air outlet 12, and a door body 2 rotatably connected to the opening side of the box body 1;

[0032] Among them, at least two spaced-apart plate members 21 are provided on the door body 2. An inner-door air duct 22 is formed between at least two of the plate members 21. The bottom of the inner-door air duct 22 should be导通 to the outside to intake air during the heat dissipation process. A wind guiding structure 3 is installed between at least two of the plate members 21. The wind guiding structure 3 is connected to the air inlet duct 11, and the joint surface between the two is at a predetermined angle with the bottom surface of the box body 1. Specifically, the predetermined angle in this embodiment is sixty degrees.

[0033] That is, in the present utility model, by adopting the method of connecting the inner-door air duct 22 with the air inlet duct 11, when dissipating heat, the inner-door air duct 22 intakes air to dissipate heat from the door body 2, thus effectively reducing the temperature of the door body 2.

[0034] In some embodiments, the box body 1 in the present utility model includes an inner container 13 and an outer shell 14 sleeved outside the inner container 13. A partition 15 is fixedly connected to the inner side of the outer shell 14. A middle plate 16 and a top plate 17 are sequentially and spacedly installed above the partition 15. A heat dissipation fan 18 is fixed between the middle plate 16 and the top plate 17;

[0035] The air outlet 12 is formed between the middle plate 16 and the top plate 17.

[0036] In addition, a control box area 19 is formed between the partition 15 and the upper part of the outer shell 14. The control box area 19 is used to install electrical components. During the heat dissipation process, when the heat dissipation fan 18 blows the heat out along the middle plate 16 and the top plate 17, the temperature in the control box area 19 can also be reduced to ensure the temperature in the control box area 19, so as to reduce the temperature of the electrical components in the control box area 19, such as control knobs, power boards, etc., to ensure the stability of the work.

[0037] Based on the above embodiments, in this embodiment, the air inlet duct 11 includes a main air duct 111 formed between the inner container 13 and the outer shell 14. Of course, in this embodiment, a plurality of through holes should be opened at the bottom of the outer shell 14, and the plurality of through holes intake air. The main air duct 111 is in a U-shaped structure. During heat dissipation, the heat dissipation fan 18 rotates at a high speed, and the external air flow intakes air through the bottom of the outer shell 14, and then the heat dissipation fan 18 discharges the air flow out along the air outlet 12 to achieve the cooling of the inside of the box body 1;

[0038] Furthermore, an auxiliary air duct 112 is formed between the partition 15 and the middle plate 16. The middle plate 16 is opened at the heat dissipation fan 18 and bent downward to form a first air guide groove 161. The top of the top plate 17 is provided with a second air guide groove 171. The connection between the partition 15, the middle plate 16 and the top plate 17 is provided with a third air guide groove 151. The designed auxiliary air duct 112 is used to connect the door air duct 22 inside the door body 2, that is, when the heat dissipation fan 18 rotates at high speed to dissipate heat, the external air flow can also be sucked in along the door air duct 22, and then discharged outward along the exhaust port 12 through the auxiliary air duct 112 to achieve cooling of the inside of the door body 2.

[0039] Preferably, in the present invention, the top of the inner container 13 is bent to form a stop surface 131, and the stop surface 131 covers the opening side of the exhaust port 12 and the auxiliary air duct 112;

[0040] The stop surface 131 is an inclined surface in the auxiliary air duct 112, and an air inlet is provided on the inclined surface. The stop surface 131 is located in front of the exhaust port 12 and an air outlet is provided. Preferably, the extension line of the inclined surface in this embodiment is set at an angle of sixty degrees to the bottom of the box body 1. The design purpose is to adapt the inclined angle to the air guide structure 3. Since the airflow direction in the right-angle flow channel changes suddenly by 90 degrees, this will cause greater friction loss and local loss. Therefore, the use of inclined surface matching can improve the flow stability of the airflow.

[0041] In addition, in this embodiment, there are four panels 21, and three door air ducts 22 are formed between the four panels 21. Specifically, in this embodiment, the four panels 21 are respectively set as door outer glass, door middle window glass 1, door middle window glass 2 and door inner window. The panels 21 are connected, supported and separated by the frame of the door body 2. Of course, the sides of the frame of the door body 2 should be sealed with the sides of each panel 21 to ensure the up and down flow of air.

[0042] In some embodiments, the air-guiding structure 3 in the present invention includes an upper horizontal surface 31, an inclined surface 32 and a lower longitudinal surface 33 connected in sequence, and end surfaces 34 are fixed at both ends of the upper horizontal surface 31, the inclined surface 32 and the lower longitudinal surface 33, wherein an air hole 35 is opened on the end surface of the inclined surface 32.

[0043] In addition, a support plate 36 is fixedly installed at the bottom of the inclined surface 32 in the present invention, and a plurality of protrusions 37 are formed at intervals on the bottom of the support plate 36. The protrusions 37 are inserted into the air duct 22 in the door. By adopting the design of the protrusions 37, the installation and positioning accuracy of the air guide structure 3 can be achieved, and the outside can also support the tops of each plate 21.

[0044] It should be noted that in this embodiment, claws 38 are also formed on both sides of the end face 34, and a slot adapted to the claws 38 is opened on the frame of the door body 2. That is to say, in the present invention, when the air guide structure 3 needs to be installed, the claws 38 on both sides of the air guide structure 3 are inserted above the frame of the door body 2. Since the two sides of the frame are provided with the slots, the air guide structure 3 can be installed and positioned when the claws 38 are connected to the slots, and the assembly method is simple.

[0045] It should be noted that, in the present invention, the angle between the extension line of the inclined surface 32 and the bottom of the box body 1 is sixty degrees.

[0046] In summary, the present invention adopts a structural design of three inner-door air ducts 22 inside the door body 2. Since the inner-door air ducts 22 are connected to the air inlet duct 11, when heat dissipation operation is performed inside the box body 1, the inner-door air ducts 22 will suck the external airflow into the air inlet duct 11 and discharge it along the exhaust port 12. In this way, heat dissipation of the door body 2 can be achieved, which can not only reduce the temperature of the door body 2, but also effectively reduce the temperature of the power board, avoid scalding users and damage to components on the power board, greatly improve the performance of the burning box product, and the product is safe and reliable to use.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
