Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to a door structure, cooking equipment and a stove-integrated cooking machine. Background Art

[0002] Cooking appliances like steam ovens generate a significant amount of heat during operation, causing the door to heat up significantly. To ensure the proper functioning of electronic components like cameras inside the door, heat dissipation ducts are typically designed into the door to reduce this temperature.

[0003] However, in integrated appliances like stove-integrated cooking machines, when the cooker and steam oven operate simultaneously, a relatively enclosed, high-temperature space is created between them. This results in high temperatures in the air entering the air duct, which in turn affects heat dissipation and makes it difficult to effectively reduce the door temperature. In particular, when choosing wooden door panels that match the kitchen's decor to meet the aesthetic requirements of integrated kitchens, due to the poor heat resistance of wood, long-term exposure to high temperatures can easily cause deformation, which not only affects the aesthetics but also further exacerbates heat dissipation difficulties. Summary of the Invention

[0004] Based on this, it is necessary to provide a door structure, cooking equipment and stove-integrated cooking machine to address the above problems, so as to improve the heat dissipation effect of the door structure.

[0005] The present invention first provides a door body structure, including: a door main body, which is provided with a U-shaped air duct, and the openings at both ends of the U-shaped air duct are facing downward, and the U-shaped air duct includes an air inlet section, a heat dissipation section and an air outlet section connected in sequence, and the top of the air inlet section is provided with an air outlet; a functional component, which is provided in the heat dissipation section; a first heat dissipation component, which is provided in the air inlet section, and the first heat dissipation component includes a first fan with an outlet facing the heat dissipation section; and a second heat dissipation component, which is provided in the air inlet section and is located below the first heat dissipation component, and the second heat dissipation component includes a second fan with an outlet facing the first fan.

[0006] In the above-mentioned door structure, when working, the first fan and the second fan run simultaneously, the second fan draws the cold air below the door structure into the air inlet section through the lower end opening of the air inlet section and blows it to the first fan, the first fan blows part of the cold air to the functional components of the heat dissipation section to cool the functional components and ensure the normal operation of the functional components, and the hot air is finally discharged through the lower end opening of the air outlet section; the gas in the U-shaped air duct can also cool the entire door body; the excess cold air in the air inlet section can also be discharged from the air outlet at the top of the air inlet section to cool the space above; through the relay cooperation of the first fan and the second fan, it is ensured that the cold air below the door structure enters the U-shaped air duct, and the high-temperature gas above the door structure is reduced from entering the U-shaped air duct through the air outlet, thereby improving the heat dissipation effect of the door structure, meeting the heat dissipation requirements, preventing the door body from deforming at high temperature, and maintaining the aesthetics of the door structure.

[0007] In one embodiment, the door body is also provided with a heat dissipation space, and the U-shaped air duct is located on the periphery of the heat dissipation space; the door body structure also includes a third heat dissipation component, the third heat dissipation component is provided in the air inlet section and is located below the second heat dissipation component, and the third heat dissipation component includes a third fan with its outlet facing the heat dissipation space.

[0008] With this arrangement, when the third fan is running, the cold air below the door structure is sucked in through the opening at the lower end of the air inlet section and blown toward the heat dissipation space and the heat dissipation section, thereby enhancing the heat dissipation effect on the door body and functional components; the third fan can also relay the cold air to the second fan to form an air pressure gradient from bottom to top in the air inlet section, ensuring that the U-shaped air duct continuously draws in cold air from below the door structure.

[0009] In one embodiment, the door body structure also includes a first lighting component arranged between the air inlet section and the heat dissipation space, the first lighting component extends along the height direction of the door body, and the outlet of the second fan faces the first fan and the first lighting component; and / or, the door body structure also includes a second lighting component arranged between the air outlet section and the heat dissipation space, the second lighting component extends along the height direction of the door body.

[0010] With such an arrangement, the first lighting assembly and the second lighting assembly can provide uniform lighting to the inner pot of the cooking device, and the gas in the U-shaped air duct and the heat dissipation space can cool the first lighting assembly and the second lighting assembly.

[0011] In one embodiment, the third heat dissipation assembly further includes a third air guide, and the third air guide is provided with a third inlet and a third outlet respectively connected to the outlet of the third fan and the heat dissipation space, and the cross-sectional area of ​​the third outlet is smaller than the cross-sectional area of ​​the third inlet.

[0012] With such arrangement, the third air guide member can direct all the wind blown out by the third fan into the heat dissipation space, and can increase the gas flow rate from the third outlet to the heat dissipation space, thereby improving the heat dissipation effect and heat dissipation efficiency of the door body.

[0013] In one embodiment, the functional component includes a shell and a camera component arranged in the shell, and a second inlet and a second outlet are respectively provided at both ends of the shell. The first heat dissipation component also includes a first air guide member, and the first air guide member is provided with a first inlet and a first outlet respectively connected to the outlet of the first fan and the second inlet.

[0014] With this arrangement, the first air guide can guide all the wind blown out by the first fan into the housing to improve the heat dissipation effect and heat dissipation efficiency of the camera component in the housing, and the hot air in the housing is discharged to the heat dissipation section through the second outlet.

[0015] In one embodiment, the door body includes a bracket assembly and a glass assembly and an outer door panel respectively arranged on both sides of the bracket assembly, and the bracket assembly and the glass assembly are arranged to form the U-shaped air duct.

[0016] With this arrangement, the door body adopts a multi-layer structure, which can reduce the temperature inside the U-shaped air duct and the outer door panel.

[0017] In one embodiment, the bracket assembly includes a fixed bracket arranged on a side of the outer door panel facing the glass assembly, the fixed bracket includes a protrusion protruding toward the glass assembly, and an insulating space is formed between the protrusion and the outer door panel, and the thickness H of the insulating space satisfies: 8mm≤H≤12mm.

[0018] Such a setting prevents the thickness H of the insulation space from being too small, resulting in poor insulation effect, and ensures that the temperature of the outer door panel can be reduced; prevents the thickness H of the insulation space from being too large, resulting in the overall thickness of the door structure being too large, or causing the thickness of the heat dissipation space between the raised part and the middle glass to be too small, thereby affecting the heat dissipation effect of the third heat dissipation component.

[0019] In one embodiment, the outer door panel is detachably connected to the bracket assembly; and / or the outer door panel is a wooden door panel.

[0020] With this arrangement, it is possible to select outer door panels that match the kitchen decoration style according to the aesthetic requirements of the integrated kitchen, thereby improving the aesthetics of the door structure and facilitating the assembly and maintenance of the door body and the various components inside the door body.

[0021] In one embodiment, the first fan is disposed in a third of the air inlet section close to one end of the air outlet, and the second fan is disposed in a half of the air inlet section away from one end of the air outlet.

[0022] This arrangement ensures that the cold air below the door structure enters the U-shaped air duct, preventing the high-temperature gas above the door structure from entering the U-shaped air duct through the air outlet, thereby improving the heat dissipation effect of the door structure.

[0023] The present invention also provides a cooking device comprising the door structure described above.

[0024] The present invention also provides a stove-integrated cooking machine, comprising a stove and the cooking device as described above, wherein the stove is arranged above the cooking device.

[0025] With this arrangement, the cold air discharged from the air vents above the door structure can lower the temperature in the relatively closed high-temperature space formed between the stove and the cooking equipment, ensuring the normal operation of the stove-integrated cooking machine.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0041] Cooking equipment such as steam ovens generate a large amount of heat when in operation, causing the door temperature to rise significantly. To ensure the normal operation of electronic components such as cameras inside the door, a heat dissipation duct structure is usually designed inside the door to reduce the door temperature. However, in integrated appliances such as stove-integrated cooking machines, when the stove and steam oven are working at the same time, a high-temperature space that should be relatively closed is formed between the two, causing the temperature of the gas entering the air duct to be high, thereby affecting the heat dissipation effect and making it difficult to effectively reduce the door temperature. In particular, to meet the aesthetic requirements of integrated kitchens, when choosing wooden door panels that match the kitchen decoration style, due to the poor temperature resistance of wood materials, generally required to be below 65°C, they are prone to deformation when exposed to high temperature environments for a long time, which not only affects the aesthetics, but also further aggravates the heat dissipation difficulties.

[0042] In order to solve the above problems, Figures 1 to 8 As shown, the present invention provides a door structure, cooking equipment and stove-integrated cooking machine to improve the heat dissipation effect of the door structure.

[0043] like Figures 1 to 2 As shown, the height direction of the door structure is defined as the Z-axis direction shown in the figure, and the width direction of the door structure is defined as the X-axis direction shown in the figure.

[0044] like Figures 1 to 2 As shown, specifically, the door structure can be used for cooking equipment such as steam ovens, and the door structure includes a door body 1, a functional component 2, a first heat dissipation component 3 and a second heat dissipation component 4, wherein: the door body 1 is provided with a U-shaped air duct 11, both ends of the U-shaped air duct 11 are opening downward, the U-shaped air duct 11 includes an air inlet section 111, a heat dissipation section 112 and an air outlet section 113 connected in sequence, and an air outlet 114 is provided at the top of the air inlet section 111; the functional component 2 is provided in the heat dissipation section 112; the first heat dissipation component 3 is provided in the air inlet section 111, and the first heat dissipation component 3 includes a first fan 31 with an outlet facing the heat dissipation section 112; the second heat dissipation component 4 is provided in the air inlet section 111, and is located below the first heat dissipation component 3, and the second heat dissipation component 4 includes a second fan 41 with an outlet facing the first fan 31.

[0045] In the door structure provided by the embodiment of the present invention, during operation, the first fan 31 and the second fan 41 operate simultaneously. The second fan 41 draws cold air from below the door structure into the air inlet section 111 through the lower opening of the air inlet section 111 and blows it toward the first fan 31. The first fan 31 blows some of the cold air toward the functional components 2 in the heat dissipation section 112 to cool them and ensure their normal operation. The hot air is eventually discharged through the lower opening of the air outlet section 113. Simultaneously, the air within the U-shaped air duct 11 can also cool the entire door body 1. Furthermore, excess cold air within the air inlet section 111 can be discharged through the air vent 114 at the top of the air inlet section 111. When a stove 200 or other equipment is located above the cooking device, the cold air discharged from the air vent 114 can also cool the space above. In this way, the first fan 31 and the second fan 41 work in relay to ensure that the cold air entering the U-shaped air duct 11 is from below the door structure, and reduce the high-temperature gas above the door structure from entering the U-shaped air duct 11 through the air outlet 114, thereby improving the heat dissipation effect of the door structure, and when the door body 1 adopts a wooden door panel, it can also meet the heat dissipation requirements, prevent the door body 1 from being deformed by high temperature, and maintain the aesthetics of the door structure.

[0046] Among them, the functional component 2 may include functional elements such as a camera component 22, a lighting component, and a temperature measurement component.

[0047] like Figure 6As shown, in one embodiment, the functional component 2 includes a housing 21 and a camera assembly 22 disposed within the housing 21. The housing 21 is provided with a second inlet 211 and a second outlet 212 at both ends. The first heat dissipation assembly 3 further includes a first air guide 32. The first air guide 32 is provided with a first inlet 321 and a first outlet 322 that are connected to the outlet of the first fan 31 and the second inlet 211, respectively. The first air guide 32 can guide all the air blown by the first fan 31 into the housing 21 to improve the heat dissipation effect and heat dissipation efficiency of the camera assembly 22 within the housing 21. The hot air within the housing 21 is discharged to the heat dissipation section 112 through the second outlet 212. The camera assembly 22 may include components such as a camera and a circuit board.

[0048] Specifically, the first air guide 32 includes a first bottom shell 323 and a first top shell 324 that enclose an air guide channel, a first inlet 321, and a first outlet 322. The first bottom shell 323 and the first top shell 324 are detachably connected, and the first fan 31 is mounted on the first bottom shell 323 to facilitate the production and assembly of the first heat dissipation assembly 3. The housing 21 includes a second bottom shell 213 and a second top shell 214 that enclose an accommodating space for accommodating the camera assembly 22, a second inlet 211, and a second outlet 212. The second bottom shell 213 and the second top shell 214 are detachably connected to facilitate the production and assembly of the functional component 2. Alternatively, the first air guide 32 and the housing 21 can also be integrally formed.

[0049] Of course, in other embodiments, the first air guide 32 can be omitted, and the air outlet of the first fan 31 can be directly directed toward the housing 21. Some cold air enters the housing 21 through the second inlet 211 to dissipate heat from the camera assembly 22, while the remaining cold air flows outside the housing 21 to dissipate heat from the entire functional component 2. Alternatively, the housing 21 can be omitted, and the camera assembly 22 can be directly mounted on the heat dissipation section 112.

[0050] like Figure 3 As shown, in one embodiment, the second heat dissipation assembly 4 further includes a base 42, and the second fan 41 is disposed on the base 42. The base 42 is provided with an air guide groove 421 to guide the air blown by the second fan 41 to the first fan 31. The first air guide 32 is provided with a first inlet 321 and a first outlet 322, which are respectively connected to the outlet of the first fan 31 and the second inlet 211. Of course, in other embodiments, the base 42 may be omitted; alternatively, the second heat dissipation assembly 4 may include a top shell that is surrounded by the base 42 to form an air guide channel.

[0051] like Figures 1 to 2As shown, the door body 1 further comprises a heat dissipation space 12, with a U-shaped air duct 11 positioned around the periphery of the heat dissipation space 12. The door structure also includes a third heat dissipation assembly 5, which is located within an air inlet section 111 and below the second heat dissipation assembly 4. The third heat dissipation assembly 5 includes a third fan 51, whose outlet faces the heat dissipation space 12. When the third fan 51 is in operation, it draws cool air from below the door structure through the lower opening of the air inlet section 111 and blows it toward the heat dissipation space 12. Simultaneously, air within the heat dissipation space 12 also flows toward the heat dissipation section 112, dissipating heat from the entire functional assembly 2 outside the housing 21. This enhances the heat dissipation effect on the door body 1 and the functional assembly 2. Furthermore, because the third fan 51 is located below the second fan 41, according to the principle of least resistance, the third fan 51 can relay the cool air to the second fan 41, creating a bottom-to-top pressure gradient within the air inlet section 111, ensuring that the U-shaped air duct 11 continuously draws cool air from below the door structure.

[0052] like Figure 7 As shown, in one embodiment, the third heat dissipation assembly 5 further includes a third air guide 52 having a third inlet 521 and a third outlet 522, each connected to the outlet of the third fan 51 and the heat dissipation space 12, respectively. The cross-sectional area of ​​the third outlet 522 is smaller than that of the third inlet 521. The third air guide 52 is capable of directing all of the air blown out by the third fan 51 into the heat dissipation space 12. Furthermore, since the cross-sectional area of ​​the third outlet 522 is smaller than that of the third inlet 521, the air flow rate from the third outlet 522 to the heat dissipation space 12 is increased, thereby further improving the heat dissipation effect and efficiency of the door body 1. In the illustrated embodiment, the ratio of the cross-sectional area of ​​the third outlet 522 to the cross-sectional area of ​​the third inlet 521 is approximately 2 / 3. The third outlet 522 is a strip-shaped opening extending along the width of the door structure. The airflow blown out through the third outlet 522 can achieve uniform cooling over a large area of ​​the high-temperature area of ​​the door body 1 facing the inner pot of the cooking device.

[0053] Specifically, the third air guide 52 includes a third bottom shell 523 and a third top shell 524 that enclose and form an air guide channel, a third inlet 521, and a third outlet 522. The third bottom shell 523 and the third top shell 524 are detachably connected, and the third fan 51 is mounted on the third bottom shell 523 to facilitate the production and assembly of the third heat dissipation assembly 5. Alternatively, the third air guide 52 can also be integrally formed.

[0054] Of course, in other embodiments, the third outlet 522 of the third air guide 52 may also be partially oriented towards the heat dissipation space 12 and partially oriented towards the second fan 41; or, the third air guide 52 may be omitted and the air outlet of the third fan 51 may be directly oriented towards the heat dissipation space 12.

[0055] like Figures 1 to 2As shown, in one embodiment, the door structure further includes a first lighting assembly 6 disposed between the air inlet section 111 and the heat dissipation space 12, and a second lighting assembly 7 disposed between the air outlet section 113 and the heat dissipation space 12. Both the first lighting assembly 6 and the second lighting assembly 7 extend along the height of the door body 1, and the outlet of the second fan 41 faces the first fan 31 and the first lighting assembly 6. The first lighting assembly 6 and the second lighting assembly 7 can provide uniform illumination of the cooking device's inner pot, improving the image quality of the camera assembly 22. Furthermore, the first lighting assembly 6 can separate the air inlet section 111 from the heat dissipation space 12, and the second lighting assembly 7 can separate the air outlet section 113 from the heat dissipation space 12, thereby ensuring the proper flow of air within the air inlet section 111, the air outlet section 113, and the heat dissipation space 12. Some of the cold air blown out from the second fan 41 can cool the first lighting assembly 6, ensuring its proper operation. Specifically, the outlet of the second fan 41 is arranged at an angle relative to the height of the door structure, so that some of the cold air blown out by the second fan 41 flows toward the first fan 31, and the remaining cold air flows toward the first lighting assembly 6. The air within the air outlet section 113 cools the second lighting assembly 7, ensuring its normal operation. Simultaneously, the air within the heat dissipation space 12 also cools the first and second lighting assemblies 6 and 7.

[0056] Of course, in other embodiments, only the first lighting assembly 6 or only the second lighting assembly 7 may be provided; or, the lighting assembly may be provided at other positions in the door body 1 according to actual needs, and the embodiment of the present invention does not impose any specific restrictions here.

[0057] like Figures 3 to 5 As shown, the door body 1 includes a bracket assembly 13, a glass assembly 14 and an outer door panel 15 respectively disposed on either side of the bracket assembly 13. The bracket assembly 13 and the glass assembly 14 enclose a U-shaped air duct 11. Thus, the door body 1 adopts a multi-layer structure, which can reduce the temperature inside the U-shaped air duct 11 and the outer door panel 15. Furthermore, the door body 1 has a simple structure, which is easy to process and assemble.

[0058] Specifically, the bracket assembly 13 includes a fixed bracket 131, a top bracket 133, a shielding bracket 134 and two side brackets 132. The outer door panel 15 is arranged on one side of the fixed bracket 131. The top bracket 133 and the two side brackets 132 are arranged on the side of the fixed bracket 131 away from the outer door panel 15. The glass assembly 14 includes a stacked middle glass 141 and an inner glass 142. The middle glass 141 is arranged on the side of the top bracket 133 and the two side brackets 132 away from the fixed bracket 131. The inner glass 142 is arranged On the side of the middle glass 141 facing away from the top bracket 133 and the two side brackets 132, the middle glass 141, the fixed bracket 131, the top bracket 133 and the two side brackets 132 are arranged to form a U-shaped air duct 11. The shielding bracket 134 is arranged on the side of the top bracket 133 facing the U-shaped air duct 11, so that the gas in the heat dissipation section 112 can change its flow direction and flow toward the air outlet section 113 after hitting the shielding bracket 134, thereby preventing the high-temperature gas from being discharged toward the top of the door body 1 and causing the temperature of the space above the cooking equipment to rise.

[0059] like Figure 3 and Figure 5 As shown, the fixing bracket 131 includes a protruding portion 1311 protruding toward the glass assembly 14, and a heat-insulating space 16 is formed between the protruding portion 1311 and the outer door panel 15. The thickness H of the heat-insulating space 16 satisfies: 8mm≤H≤12mm. Among them, H can be any value within the range of 8mm to 12mm, such as 8mm, 9mm, 10mm, 11mm, 12mm, etc. In this way, H≥8mm, which prevents the thickness H of the heat-insulating space 16 from being too small, resulting in poor heat insulation effect, and ensures that the temperature of the outer door panel 15 can be reduced. H≤12mm, which prevents the thickness H of the heat-insulating space 16 from being too large, resulting in an excessively large overall thickness of the door structure, or causing the thickness of the heat dissipation space 12 between the protruding portion 1311 and the middle glass 141 to be too small, thereby affecting the heat dissipation effect of the third heat dissipation assembly 5.

[0060] Specifically, the fixed bracket 131 also includes a fixed portion 1312 arranged on the periphery of the raised portion 1311. The middle glass 141, the fixed portion 1312, the top bracket 133 and the two side brackets 132 are arranged to form a U-shaped air duct 11. A heat dissipation space 12 is formed between the raised portion 1311 and the middle glass 141. The first heat dissipation component 3, the second heat dissipation component 4, the third heat dissipation component 5 and the functional component 2 are all arranged on the fixed portion 1312. The first lighting component 6 and the second lighting component 7 are arranged at the connection between the fixed portion 1312 and the raised portion 1311.

[0061] In one embodiment, the outer door panel 15 is detachably connected to the bracket assembly 13. This allows the user to select an outer door panel 15 that matches the desired aesthetic of the integrated kitchen, enhancing the aesthetics of the door structure while also facilitating assembly and maintenance of the door body 1 and its internal components. The outer door panel 15 can be made of wood, but can also be made of glass, metal, or other materials. Of course, in other embodiments, the outer door panel 15 and bracket assembly 13 can also be non-detachable, depending on actual needs.

[0062] like Figures 1 to 2 As shown, when a cooker 200 is installed above the cooking equipment, the air temperature between the cooker 200 and the cooking equipment is relatively high. To further prevent hot air between the cooker 200 and the cooking equipment from entering the U-shaped air duct 11 through the air vent 114, the first fan 31 is located in the third of the air inlet section 111 near the air vent 114, and the second fan 41 is located in the half of the air inlet section 111 away from the air vent 114. The third of the air inlet section 111 near the air vent 114 refers to the top third of the air inlet section 111 along the height of the door body 1; the half of the air inlet section 111 away from the air vent 114 refers to the bottom half of the air inlet section 111 along the height of the door body 1. This further ensures that cool air enters the U-shaped air duct 11, preventing hot air above the door structure from entering the U-shaped air duct 11 through the air vent 114, thereby improving the heat dissipation efficiency of the door structure.

[0063] like Figure 8 As shown, the present invention also provides a cooking device including the above-mentioned door structure. External cold air enters the door structure through one side of the bottom of the door structure, and hot air exits the door structure through the other side of the bottom of the door structure, thereby ensuring reliable overall cooling of the interior of the door structure. At the same time, some cold air is discharged from the air vent 114 above the door structure, thereby preventing the temperature above the cooking device from becoming too high. The cooking device may be a steamer, oven, steam oven, microwave oven, etc., and the embodiments of the present invention are not specifically limited thereto.

[0064] like Figure 8As shown, the present invention also provides a stove-integrated cooking machine, comprising a stove 200 and the aforementioned cooking equipment, with the stove 200 positioned above the cooking equipment. Specifically, the stove-integrated cooking machine also includes a cabinet 300, with the stove 200 positioned atop the cabinet 300 and the cooking equipment embedded within the cabinet 300. The outer door panel 15 can be made of the same material as the door panel of the cabinet 300, thereby enhancing the overall aesthetics of the stove-integrated cooking machine. Cool air discharged from the air vents 114 above the door structure can reduce the temperature within the relatively enclosed, high-temperature space between the stove 200 and the cooking equipment, ensuring the proper operation of the stove-integrated cooking machine.

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0066] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
