Description

Technical Field

[0001] The utility model relates to the technical field related to cooking equipment, in particular to a cooling structure and a stove-steaming and baking all-in-one machine. Background Art

[0002] While ensuring product functionality, the stove-steam-and-bake machine has a relatively high space utilization rate in the height direction and is more space-saving. In order to improve the space utilization rate in the height direction, most existing stove-steam-and-bake machines adopt a top-mounted design with hot air blower and heating tube, and the hot air blower is located inside the stove chassis.

[0003] The problem with this configuration is that the temperature inside the stove chassis will be higher, so a cooling system needs to be designed to cool the inside of the stove to ensure that the parts inside the stove can be used normally;

[0004] At present, the cooling systems inside stove-steaming and baking machines are mostly used to dissipate heat from heat sources such as hot air blowers. However, since components such as knobs are far away from the hot air blowers, the cooling effect of the cooling system on them is relatively poor. As a result, components such as knobs may accumulate heat, which may affect the service life of the knobs or even directly cause damage to the knobs. Utility Model Content

[0005] Based on this, it is necessary to provide a cooling structure and a stove-steam-bake all-in-one machine that will not generate heat accumulation in the internal parts of the stove to address the problem that the knobs inside the stove in the current stove-steam-bake all-in-one machine are prone to heat accumulation, thus affecting normal use.

[0006] The present application first provides a cooling structure, including a panel, an air duct housing, a knob, and a heat conducting plate;

[0007] The air duct housing is fitted to the lower surface of the panel to form an air duct therebetween, the panel is provided with an air inlet connected to the air duct, a fan is provided in the air duct, and the air duct housing is provided with an air outlet corresponding to the outlet of the fan;

[0008] The knob passes through the air duct housing and the air inlet until a portion of the knob protrudes from the panel, so as to form an air inlet gap between the knob and the air inlet;

[0009] One end of the heat conducting plate is in contact with the air duct housing, and the other end is in contact with the knob.

[0010] In one of the embodiments, the heat conducting plate is in contact with the bottom surface of the knob.

[0011] In one of the embodiments, the air duct housing includes a first step surface, a second step surface, and a third step surface which are distributed in sequence and whose heights decrease successively, the knob passes through the first step surface, the fan is arranged on the third step surface, and the heat conduction plate is in contact with the outer bottom surface of the air duct housing corresponding to the second step surface.

[0012] In one embodiment, the edge of the second step surface close to the third step surface has a liquid retaining rib, and the second step surface is also provided with a liquid discharge port that passes through the air duct housing, and the liquid discharge port is located at the angle formed by the liquid retaining rib and the side wall of the air duct housing.

[0013] In one of the embodiments, a drainage protrusion is provided on the second step surface, the drainage port is opened on the drainage protrusion, and the height of the drainage protrusion is lower than the liquid retaining rib.

[0014] In one of the embodiments, the air duct housing is provided with a knob hole, the knob passes through the knob hole, a waterproof cover is fixed on the knob and is located inside the air duct housing, and the projection of the waterproof cover along the vertical direction completely covers the knob hole.

[0015] In one embodiment, the waterproof cover is in the shape of a truncated cone.

[0016] In one of the embodiments, the air duct housing has a waterproof protrusion facing the panel, the knob hole is opened on the waterproof protrusion, and the projection of the waterproof cover along the vertical direction completely covers the top surface of the waterproof protrusion.

[0017] In one of the embodiments, the waterproof protrusion is in a truncated cone shape, the side surface of the waterproof protrusion is parallel to the side surface of the waterproof cover, and the projections of the two along the horizontal direction at least partially overlap.

[0018] A second aspect of the present application provides a stove-steaming and baking machine, comprising the above-mentioned cooling structure.

[0019] This cooling structure uses the opening through which the knob on the panel passes as an air inlet. Since the knob is far away from the high-temperature area, the air entering the air duct through the air inlet is low-temperature air, and the flow of low-temperature air can cool the knob. In addition, the low-temperature air flows along the air duct under the action of the fan, which can cool the air duct casing. The air duct casing and the knob are connected by a heat conduction plate, which can further cool the knob. The dual cooling effects of the low-temperature air flow and the heat exchange of the heat conduction plate can ensure that the normal operation of the knob will not be affected by heat accumulation.

[0035] Please combine Figures 1 to 4 As shown, the present application first provides a cooling structure, including a panel 10, an air duct housing 20, a knob 30 and a heat conducting plate 40; the air duct housing 20 is fitted with the lower surface of the panel 10 to form an air duct therebetween, the panel 10 is provided with an air inlet 11 connected to the air duct, a fan 50 is arranged in the air duct, and the air duct housing 20 is provided with an air outlet 21 corresponding to the outlet of the fan 50; the knob 30 passes through the air duct housing 20 and the air inlet 11 to partially protrude from the panel 10 to form an air intake gap between the knob 30 and the air inlet 11; one end of the heat conducting plate 40 is fitted with the air duct housing 20, and the other end is fitted with the knob 30.

[0036] Specifically, the air duct housing 20 is sealed and fitted to the panel 10 to form an air duct. When the fan 50 is running, negative pressure is generated inside the air duct. External air enters the air duct through the air inlet 11 and is sucked into the fan 50. After passing through the outlet of the fan 50, it is discharged from the air outlet 21 of the air duct to dissipate heat in the high temperature area.

[0037] In the present application, the opening through which the knob 30 passes on the panel 10 is used as the air inlet 11. Since the knob 30 is far away from the high temperature zone, the air entering the air duct through the air inlet 11 is low-temperature air, and the flow of low-temperature air can cool the knob 30. In addition, the low-temperature air flows along the air duct under the action of the fan 50, which can cool the air duct housing 20. The air duct housing 20 and the knob 30 are connected by the heat conduction plate 40, so the knob 30 can be further cooled.

[0038] The dual cooling effect of low-temperature air flow and heat exchange of the heat conducting plate 40 ensures that the knob 30 will not be affected in normal operation due to heat accumulation.

[0039] Please refer to Figure 4 as well as Figure 5 As shown, in some embodiments, the heat conducting plate 40 is fitted with the bottom surface of the knob 30; it is not difficult to understand that low-temperature air enters the air duct through the air inlet 11, thereby cooling the upper part of the knob 30, and the heat conducting plate 40 is fitted with the bottom surface of the knob 30, which can cool the bottom of the knob 30, and the cooling effect of the knob 30 is improved by cooling and dissipating heat on both the upper and lower sides at the same time, further reducing the possibility of heat accumulation.

[0040] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, the cooling structure also includes a display screen 60, which is fixed to the bottom surface of the panel 10 and directly opposite the fan 50; on the one hand, the low-temperature air entering the air duct from the air inlet 11 can cool the display screen 60 when flowing through the display screen 60 area, and on the other hand, the low-temperature air layer can also insulate the display screen 60, further reducing the possibility of heat accumulation in the display screen 60.

[0041] Please refer to Figure 2 As shown, in some embodiments, the air outlet of the air duct housing 20 faces the hot air blower 200, so that the low-temperature air blown out through the air duct can directly blow the hot air blower 200, thereby improving the cooling protection effect of the cooling structure of the present application.

[0042] Please combine Figure 3 as well as Figure 5 As shown, in some embodiments, the air duct housing 20 includes a first step surface 20a, a second step surface 20b and a third step surface 20c which are distributed in sequence and whose heights decrease successively, the knob 30 passes through the first step surface 20a, the fan 50 is arranged on the third step surface 20c, and the heat conducting plate 40 is in contact with the outer bottom surface of the air duct housing 20 corresponding to the second step surface 20b.

[0043] Through the air duct design with three step surfaces, after the low-temperature air enters the air duct from the air inlet 11, it flows in an oblique downward direction to enter the fan 50, and the low-temperature airflow flowing in the oblique downward direction can collide with the flat second step surface 20b to fully transfer the cold energy to the air duct housing 20 at the corresponding position, thereby increasing the cooling and heat dissipation effect of the heat conduction plate 40 attached to this position.

[0044] Please combine Figure 3 as well as Figure 5 As shown, in some embodiments, the cooling structure includes two knobs 30, two air inlets 11 are provided on the panel 10, and the air duct housing 20 includes two first step surfaces 20a, two second step surfaces 20b and a third step surface 20c, and is arranged in the order of the first step surface 20a, the second step surface 20b, the third step surface 20c, the second step surface 20b and the first step surface 20a. The two knobs 30 respectively penetrate the two first step surfaces 20a.

[0045] Please combine Figure 5 as well as Figure 6 As shown, in some embodiments, the edge of the second step surface 20b close to the third step surface 20c has a liquid retaining rib 22, and the second step surface 20b is also provided with a drainage port 23 that passes through the air duct housing 20, and the drainage port 23 is located at the angle formed by the liquid retaining rib 22 and the side wall of the air duct housing 20.

[0046] The liquid blocking rib 22 can block the liquid entering the air duct when the knob 30 is cleaned or other liquid enters the air duct, preventing it from flowing into the fan 50 and damaging the fan 50; and the drain port 23 can discharge the liquid to the chassis when there is a lot of liquid.

[0047] Preferably, a drainage protrusion 24 is provided on the second step surface 20 b , and the drainage port 23 is opened on the drainage protrusion 24 . The height of the drainage protrusion 24 is lower than the liquid retaining rib 22 .

[0048] Please refer to Figure 4 As shown, in some embodiments, the air duct housing 20 is provided with a knob hole 25 , and the knob 30 passes through the knob hole 25 . A waterproof cover 31 located inside the air duct housing 20 is fixed on the knob 30 , and the projection of the waterproof cover 31 along the vertical direction completely covers the knob hole 25 .

[0049] Preferably, the fitting clearance between the knob hole 25 and the knob 30 is small, which can play a positioning and limiting role to ensure that the knob 30 is installed in place, and the waterproof cover 31 that completely covers the knob hole 25 along the projection can play a waterproof role. When the knob 30 is cleaned or other liquid enters the air duct, it can prevent the liquid from flowing into the valve body at the bottom of the knob 30 through the knob hole 25, thereby protecting the valve body.

[0050] Please refer to Figure 4 As shown, in some embodiments, the waterproof cover 31 is in a frustum shape, which can guide the liquid entering the air duct and guide the liquid outward in the radial direction, thereby further reducing the possibility of the liquid flowing into the knob hole 25 located in the center.

[0051] Please refer to Figure 4 As shown, in some embodiments, the air duct housing 20 has a waterproof protrusion 26 facing the panel 10 , the knob hole 25 is opened on the waterproof protrusion 26 , and the projection of the waterproof cover 31 along the vertical direction completely covers the top surface of the waterproof protrusion 26 .

[0052] Preferably, the waterproof protrusion 26 is in a truncated cone shape, and the side surface of the waterproof protrusion 26 is parallel to the side surface of the waterproof cover 31, and the projections of the two along the horizontal direction at least partially overlap.

[0053] The truncated cone-shaped waterproof protrusion 26 can also guide the liquid entering the air duct, guiding the liquid outward in the radial direction, thereby further reducing the possibility of the liquid flowing into the knob hole 25 located in the center; and the side surface of the waterproof protrusion 26 at least partially overlaps with the horizontal projection of the waterproof cover 31, which can prevent water from flowing into the knob hole 25 through the gap between the two, thereby increasing the waterproof performance.

[0054] In some embodiments, the waterproof protrusion 26 is located at the first step portion 20 a . After the liquid guided by the waterproof protrusion 26 flows through the first step portion 20 a to the second step portion 20 b , it can be blocked by the liquid blocking rib 22 and discharged through the drain port 23 .

[0055] A second aspect of the present application provides a stove-steaming and baking machine, comprising the above-mentioned cooling structure.

[0056] Please refer to Figure 7 As shown, in some embodiments, the side of the air duct housing 20 is connected to an air pipe 300, and the other end of the air pipe 300 is connected to the inside of the machine;

[0057] When the fan 50 is running, negative pressure is generated inside the air duct. On the one hand, cold air is drawn in from the air inlet 11 on the panel 10 , and on the other hand, air inside the machine is extracted through the air duct 300 and blown into the inside of the chassis through the fan 50 .

[0058] Specifically, a through hole is opened on the front side of the fixed part of the oven door. When the air pipe 300 inhales air, negative pressure will be generated inside the machine. At this time, cold air will enter the machine from the through hole of the front door to cool the igniter, power board and other components inside the machine.

[0059] Although the air sucked into the air duct through the air pipe 300 will have a certain temperature rise after heat exchange with the internal parts of the machine, since the side of the machine is far away from the heat source area, the temperature is lower than that of the hot air blower 200. Therefore, even if the air is heated, it still has a cooling effect on the hot air blower 200.

[0060] Please refer to Figure 8 As shown, in some embodiments, the air duct housing 20 is connected to an air pipe 300, one end of the air pipe 300 is connected to the outlet of the fan 50, and the other end is connected to the inside of the machine.

[0061] That is, there are two air duct outlets, wherein the air outlet 21 cools down the hot air blower, and the outlet of the air duct 300 cools down the inside of the machine.

[0062] When the steaming and baking function of the machine is running, the heat from the inner pot will be conducted through the side walls to the power board, oven light, igniter and other areas inside the machine, causing the temperature to rise. Without other intervention, the temperature rise will exceed its normal usage limit.

[0063] When the machine is working, the fan 50 works synchronously, and cold air is continuously blown into the interior of the machine through the air pipe 300, thereby cooling the interior of the machine, thereby ensuring that the internal power board, furnace lamp, etc. do not exceed the normal use temperature rise limit.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
