Description

Technical Field

[0001] The present disclosure relates to the technical field of kitchen appliances, and in particular to a cooking device. Background Art

[0002] As people's quality of life continues to improve, kitchen appliances are becoming more and more abundant. Cookers, microwave ovens, ovens, steamers, etc. have gradually become essential kitchen appliances for family life. These kitchen appliances not only have relatively simple functions, but each product requires a certain amount of kitchen space, and the cost of purchasing them separately is high. In order to effectively utilize kitchen space and reduce purchase costs, the emergence of integrated stoves has been further promoted. Integrated stoves are a type of combined kitchen appliance that combines cookers, range hoods, and cooking devices, and are deeply loved by consumers.

[0003] The cooking device of the integrated stove generally has both steaming and baking functions to form a steam-bake machine with an inner pot, and the stove is located above the steam-bake machine. Most of the existing heat dissipation structures are located between the steam-bake machine and the stove. The heat dissipation structure includes a steam condensation channel and a heat dissipation fan. The heat dissipation fan can blow air into the steam condensation channel, so that the air and steam can exchange heat in the steam condensation channel, reducing the temperature of the inner pot to a certain extent. However, the fan inlet of the heat dissipation fan is located inside the heat dissipation structure. Due to the high temperature in the cooking device, the temperature of the air blown into the steam condensation channel by the heat dissipation fan is high. In this way, the temperature difference between air and steam is small, which can cool the steam, but it is difficult to cool the high-temperature inner pot.

[0004] If the fan is directly installed in the inner pot for heat dissipation, the hot air circulates inside the steam oven, and it is difficult to dissipate heat in places where the wind cannot reach. In addition, the heat dissipation structure and the heat dissipation fan occupy a large amount of space in the steam oven, the cooling effect is poor, the structure is complex, and it is difficult to disassemble and repair. Summary of the invention

[0005] Based on this, in order to solve the above problems, it is necessary to provide a cooking device.

[0006] The disclosed embodiment provides a cooking device, which includes a shell, an inner pot and a heat dissipation structure; the shell has a accommodating space; the inner pot is accommodated in the accommodating space, and the inner pot has a cooking cavity; the heat dissipation structure is arranged between the inner pot and the shell, and the heat dissipation structure includes a heat dissipation duct, a heat dissipation fan and at least one air guide pipe connected in sequence, the heat dissipation duct and the heat dissipation fan are both arranged on the bottom wall of the inner pot, and the air inlet of the heat dissipation duct is lower than the heat dissipation fan, and the other end of the air guide pipe is located on the side wall of the inner pot.

[0007] The cooking device provided in the embodiment of the present disclosure is provided with a heat dissipation duct and a heat dissipation fan at the bottom of the inner pot, and the air inlet can introduce cold air from the bottom of the inner pot from the outside of the shell, and the cold air flows to the side wall of the inner pot through the air duct, thereby cooling the side wall of the inner pot. Since the temperature at the bottom of the cooking device is relatively low and the cold air will sink, the temperature of the cold air introduced by the heat dissipation structure is relatively low, which increases the cooling effect on the inner pot when the temperature difference is large compared with the case of large internal temperature difference. At the same time, the heat dissipation structure is simple to set up, occupies a small space, and is located at the bottom of the inner pot for easy disassembly and maintenance. In addition, the air inlet of the heat dissipation duct is lower than the heat dissipation fan, which is convenient for the heat dissipation fan to suck cold air from bottom to top, which is in line with aerodynamics, increases the air intake and wind speed, and improves the heat dissipation effect and heat dissipation efficiency.

[0008] In some of the embodiments, the heat dissipation air duct includes an air inlet area, an air change area and a buffer area connected in sequence, the air inlet is located at one end of the air inlet area, the buffer area is connected to the heat dissipation fan, the air inlet area and the buffer area are horizontally arranged and the air inlet area is lower than the buffer area.

[0009] With this arrangement, cold air enters from the low air inlet area and rises to the buffer zone through the wind change area. The wind change area can change the direction of the cold air and thus change the flow rate. The buffer zone can alleviate the eddy current generated when the cold air changes direction to ensure the flow of the cold air, further improving the heat dissipation effect and efficiency.

[0010] In some embodiments, two ends of the wind changing zone are obliquely connected to the wind inlet zone and the buffer zone.

[0011] With this arrangement, the inclination of the variable wind zone reduces the resistance when the cold air flows, is more suitable for the change of direction and increase of the flow rate of the cold air, facilitates the flow of the cold air in the heat dissipation duct, and further improves the heat dissipation effect and efficiency.

[0012] In some embodiments, the upper surface of the buffer zone abuts against the bottom wall of the inner tank, the buffer zone includes a connecting portion and a buffer portion, the lower surface of the connecting portion is provided with an installation opening, and the heat dissipation fan is installed in the installation opening.

[0013] With such arrangement, the buffer zone can cool the bottom wall of the inner tank, the heat dissipation fan is installed in the heat dissipation duct through the connecting part, and the buffer zone is used to alleviate the vortex generated by the change of direction when the cold air flows in. The structure is simple and the volume is small, which conforms to aerodynamics.

[0014] In some of the embodiments, the heat dissipation duct is enclosed by a bottom plate and a top structure, the top structure includes two side plates and a top plate connected between the two side plates, the bottom plate is also provided with a sealing portion, the inner surface of the side plate abuts against the outer surface of the sealing portion; the outer surface of the side plate is provided with a clip, the edge of the bottom plate is provided with a clip, and the clip is clipped to the clip.

[0015] With such a configuration, the cooperation between the sealing part and the side plate improves the sealing performance of the heat dissipation duct, and avoids the gap after the top structure and the bottom plate are connected, which causes cold air to flow out of the heat dissipation duct. The structure of the clamping part and the clamping part is simple and convenient to set up, which simplifies the installation steps of the top structure and the bottom plate, and further improves the sealing performance of the heat dissipation duct.

[0016] In some embodiments, the distance between the bottom plate and the top plate of the wind inlet zone is greater than the distance between the bottom plate and the top plate of the buffer zone, and the distance between the bottom plate and the top plate of the wind change zone decreases along the fluid flow direction.

[0017] With this setting, the variable wind zone is set with a variable cross-section and the closer to the buffer zone, the smaller the cross-section. A large amount of cold air enters the air inlet area with a larger cross-sectional area and increases the flow rate when passing through the variable cross-section. After entering the buffer zone with a smaller cross-sectional area, it enters the fan with a faster flow rate and lower temperature, making the temperature of the cold air lower and improving the cooling effect.

[0018] In some of the embodiments, the connecting surfaces of the wind change zone, the buffer zone and the air inlet zone of the top plate are all arc surfaces; the connecting surfaces of the wind change zone, the buffer zone and the air inlet zone of the bottom plate are all arc surfaces.

[0019] The setting of the curved surface can reduce the resistance of the cold wind when it changes direction, making the wind flow smoother.

[0020] In some of the embodiments, the heat dissipation structure further includes a diverter, one end of the diverter is connected to the heat dissipation fan, and the other end of the diverter is connected to the air duct.

[0021] The setting of the splitter can divide the incoming cold air into two or more flows. Through the pressure difference and flow relationship of the fluid, the flow speed and flow direction of the gas can be changed, and different cold air can be controlled to flow out from different outlets.

[0022] In some embodiments, the diverter includes a first air outlet and a second air outlet, the first air outlet is connected to the air duct, the second air outlet is connected to the accommodating space, and the second air outlet is used to dissipate heat for the bottom wall of the inner tank.

[0023] With such a configuration, the cold air is diverted through the first air outlet and the second air outlet, and the bottom and the side of the inner liner can be cooled at the same time, so that the bottom of the inner liner is kept at a low temperature so that the cold air is not easily heated up in the cold air channel, thereby improving the heat dissipation effect and heat dissipation efficiency of the cold air and reducing the overall temperature rise of the inner liner.

[0024] In some of the embodiments, the heat dissipation fan is a negative pressure fan.

[0025] Negative pressure fans are highly efficient and can generate high negative pressure in a short period of time, quickly realize air convection, and facilitate the inhalation of external cold air. Secondly, negative pressure fans have a compact structure and are easy to install, and can be arranged and adjusted according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] refer to Figure 1 , Figure 1 The overall structure of the cooking device in the embodiment of the present disclosure is shown. The present disclosure relates to the technical field of kitchen appliances. The cooking device 100 in the embodiment of the present disclosure is a combined kitchen appliance that combines a stove, a range hood, and a cooking device, such as an integrated stove or other combined kitchen appliances.

[0039] Combination Figure 2 In an embodiment of the present disclosure, there is provided a cooking device 100, which includes a shell 1, an inner pot 2 and a heat dissipation structure 3. The shell 1 has a containing space 11. Exemplarily, the shell 1 is used to protect items in the containing space 11. The inner pot 2 is contained in the containing space 11, and the inner pot 2 has a cooking cavity (not shown). Exemplarily, food can be placed in the cooking cavity, and the overall temperature of the inner pot 2 increases when the food is cooked in the cooking cavity. The heat dissipation structure 3 is arranged between the inner pot 2 and the shell 1. Exemplarily, there is a certain distance between the outer wall of the inner pot 2 and the inner wall of the shell 1.

[0040] The heat dissipation structure 3 includes a heat dissipation duct 31, a heat dissipation fan 32 and at least one air duct 33 which are connected in sequence. The heat dissipation duct 31 and the heat dissipation fan 32 are both arranged on the bottom wall of the inner liner 2, and the air inlet of the heat dissipation duct 31 is lower than the heat dissipation fan 32, and the other end of the air duct 33 is located on the side wall of the inner liner 2. Exemplarily, under the action of the heat dissipation fan 32, the external cold air enters from the air inlet of the heat dissipation duct 31 at the lower part of the inner liner 2 through the air duct 33 to reach the side wall of the inner liner 2.

[0041] The cooking device 100 provided in the embodiment of the present disclosure is provided with a heat dissipation duct 31 and a heat dissipation fan 32 at the bottom of the inner pot 2. The air inlet can introduce cold air from the bottom of the inner pot 2 from the outside of the housing 1. The cold air flows to the side wall of the inner pot 2 through the air duct 33, thereby cooling the side wall of the inner pot 2. Since the temperature at the bottom of the cooking device 100 is relatively low and the cold air will sink, the temperature of the cold air introduced by the heat dissipation structure 3 is relatively low, and the cooling effect on the inner pot 2 is increased when the temperature difference with the internal temperature is relatively large.

[0042] At the same time, the heat dissipation structure 3 in the embodiment of the present disclosure is simple to set up, convenient to install between the inner tank 2 and the shell 1, and occupies less space. The heat dissipation duct 31 and the heat dissipation fan 32 are located at the bottom of the inner tank 2 for easy disassembly and maintenance.

[0043] In addition, the air inlet of the heat dissipation duct 31 is lower than the heat dissipation fan 32, which is conducive to the heat dissipation fan 32 to suck cold air from bottom to top, which is in line with aerodynamics, increases the air intake volume and wind speed, and the air inlet of the heat dissipation duct 31 is close to the heat dissipation fan 32, which can ensure that there is sufficient pressure to absorb cold air from the outside, thereby improving the heat dissipation effect and heat dissipation efficiency of the heat dissipation structure 3.

[0044] Exemplarily, the housing 1 is a square structure, and the inner liner 2 is also a square structure. In other embodiments, the housing 1 is a square structure, and the shape of the inner liner 2 can also be cylindrical or other shapes.

[0045] Exemplarily, the side wall of the inner liner 2 is provided with a bracket, and the air duct 33 passes through the bracket and is fixed to the inner liner 2. Exemplarily, the inner liner 2 has four side walls, each of which is provided with a bracket, and each bracket is fixed with an air duct 33, which can dissipate heat from the side walls of the inner liner 2 respectively and simultaneously, thereby increasing the heat dissipation effect.

[0046] refer to Figure 1 and Figure 2 In some embodiments, the heat dissipation air duct 31 includes an air inlet area 311, an air change area 312 and a buffer area 313 connected in sequence, the air inlet is located at one end of the air inlet area 311, the buffer area 313 is connected to the heat dissipation fan 32, the air inlet area 311 and the buffer area 313 are arranged horizontally, and the air inlet area 311 is lower than the buffer area 313. In this arrangement, after entering the low air inlet area 311, the cold air rises to the buffer area 313 through the air change area 312. The air change area 312 can change the direction of the cold air and thus change the flow rate. The buffer area 313 can alleviate the vortex generated when the cold air changes direction to ensure the flow of the cold air, further improving the heat dissipation effect and heat dissipation efficiency.

[0047] Exemplarily, the air inlet area 311 is arranged horizontally, the right end of the air inlet area 311 is an air inlet, the left end of the air inlet area 311 is connected to the lower end of the wind change area 312, the upper end of the wind change area 312 is connected to the right end of the buffer zone 313, the buffer zone 313 is also arranged horizontally, and the left end of the buffer zone 313 is connected to the heat dissipation fan 32. In other embodiments, the extension direction of the air inlet area 311 and the buffer zone 313 is the same and different from the wind change area 312. Or the air inlet area 311, the buffer zone 313 and the wind change area 312 are all arranged obliquely, but the degree of inclination of the wind change area 312 is different from that of the air inlet area 311 and the buffer zone 313.

[0048] Exemplarily, the cross-sectional areas of the air inlet area 311, the wind change area 312, and the buffer area 313 are all square. In other embodiments, the cross-sectional areas of the air inlet area 311, the wind change area 312, and the buffer area 313 are all circular, polygonal, or other shapes. It is understandable that the cross-sectional areas of the air inlet area 311, the wind change area 312, and the buffer area 313 may be different.

[0049] refer to Figures 1 to 3 In some embodiments, the two ends of the wind changing area 312 are obliquely connected to the wind inlet area 311 and the buffer area 313. In this way, the wind changing area 312 is inclined to reduce the resistance of the cold air flow, which is more suitable for the change of direction and increase of the flow rate of the cold air, and facilitates the flow of the cold air in the heat dissipation duct 31, further improving the heat dissipation effect and heat dissipation efficiency.

[0050] Exemplarily, the wind duct slope of the wind change zone 312 is 143°, which is more suitable for cold air to quickly pass through the wind change zone 312 to increase the flow rate.

[0051] refer to Figures 1 to 4 In some embodiments, the upper surface of the buffer zone 313 abuts against the bottom wall of the inner liner 2, and the buffer zone 313 includes a connecting portion 3132 and a buffer portion 3131. The lower surface of the connecting portion 3132 is provided with an installation opening 3133, and the heat dissipation fan 32 is installed at the installation opening 3133. In this way, the buffer zone 313 can cool the bottom wall of the inner liner 2, and the heat dissipation fan 32 is installed in the heat dissipation air duct 31 through the connecting portion 3132. The buffer portion 3131 is used to alleviate the vortex generated by the change of direction when the cold air flows in. The structure is simple and the volume is small, which conforms to aerodynamics.

[0052] Exemplarily, the buffer zone 313 is formed by connecting a cylindrical connecting portion 3132 and a square buffer portion 3131 , and the mounting opening 3133 is circular.

[0053] Exemplarily, the heat dissipation channel is bolted to the bottom wall of the inner tank 2, which increases the firmness of the installation.

[0054] refer to Figure 3 and Figure 4 In some embodiments, the heat dissipation duct 31 is formed by the bottom plate 310 and the top structure 30, the top structure 30 includes two side plates 301 and a top plate 302 connected between the two side plates 301, the bottom plate 310 is also provided with a sealing portion 3101, the inner surface of the side plate 301 is abutted against the outer surface of the sealing portion 3101; the outer surface of the side plate 301 is provided with a clamping member 3011, the edge of the bottom plate 310 is provided with a clamping member 3102, and the clamping member 3011 is clamped to the clamping member 3102. In this way, the cooperation between the sealing member 3101 and the side plate 301 improves the sealing performance of the heat dissipation duct 31, and avoids the gap after the top structure 30 and the bottom plate 310 are connected, which causes the cold air to flow out of the heat dissipation duct 31. The clamping member 3011 and the clamping member 3102 are simple in structure and convenient to set up, which simplifies the installation steps of the top structure 30 and the bottom plate 310, and further improves the sealing performance of the heat dissipation duct 31.

[0055] Exemplarily, the bottom plate 310 corresponding to the wind change area 312 is tilted, the bottom plates 310 corresponding to the air inlet area 311 and the buffer area 313 are all horizontally arranged, and the widths of the bottom plates 310 corresponding to the air inlet area 311, the wind change area 312 and the buffer part 3131 are the same. Exemplarily, the sealing part 3101 is convexly arranged on the bottom plate 310 and encloses an opening only toward the air inlet, forming a slide shape with the sealing part 3101.

[0056] Exemplarily, a plurality of clamping parts 3102 are symmetrically arranged at the edges of both sides of the bottom plate 310, and a plurality of clamping parts 3102 on each side are arranged at intervals along the extension direction of the bottom plate 310. A clamping groove is provided in the clamping part 3102. Exemplarily, a clamping member 3011 protrudes from the left and right sides of the side plate 301 and is arranged corresponding to the clamping member 3102. The clamping member 3011 is clamped in the clamping groove. Exemplarily, the shape of the clamping member 3011 is a triangular prism. In other embodiments, the clamping member 3011 may be a square, an irregular shape, or other shapes.

[0057] In other embodiments, the heat dissipation duct 31 may also be an integrated structure.

[0058] refer to Figure 2 and Figure 3 In some embodiments, the distance between the bottom plate 310 and the top plate 302 of the air inlet area 311 is greater than the distance between the bottom plate 310 and the top plate 302 of the buffer area 313, and the distance between the bottom plate 310 and the top plate 302 of the variable wind area 312 decreases along the fluid flow direction. In this way, the variable wind area 312 is a variable cross-section setting, and the closer to the buffer area 313, the smaller the cross-section. After a large amount of cold air enters the air inlet area 311 with a larger cross-sectional area, the flow rate is increased when passing through the variable cross-section. After entering the buffer area 313 with a smaller cross-sectional area, it enters the fan at a faster flow rate and lower temperature, so that the temperature of the cold air is lower, and the cooling effect is improved.

[0059] Exemplarily, the top plate 302 corresponding to the air inlet area 311 is arranged in parallel with the bottom plate 310. The top plate 302 corresponding to the buffer zone 313 is arranged in parallel with the bottom plate 310. The distance between the top plate 302 and the bottom plate 310 corresponding to the air inlet area 311 is greater than the distance between the top plate 302 and the bottom plate 310 corresponding to the buffer zone 313. The top plate 302 corresponding to the wind change area 312 is arranged obliquely relative to the bottom plate 310 so that the cross-sectional area of ​​the wind change area 312 closer to the buffer zone 313 is smaller.

[0060] refer to Figures 1 to 4 In some embodiments, the connecting surfaces of the wind changing area 312 of the top plate 302, the buffer area 313 and the wind inlet area 311 are all arc surfaces; the connecting surfaces of the wind changing area 312 of the bottom plate 310, the buffer area 313 and the wind inlet area 311 are all arc surfaces. The setting of the arc surface can reduce the resistance of the cold wind when changing direction, making the wind flow more smoothly.

[0061] refer to Figure 1 and Figure 5In some embodiments, the heat dissipation structure 3 further includes a flow divider 34, one end of which is connected to the heat dissipation fan 32, and the other end of which is connected to the air duct 33. The flow divider 34 can divide the incoming cold air into two or more flows, and change the flow speed and flow direction of the gas through the pressure difference and flow relationship of the fluid, so as to control different cold air to flow out from different outlets.

[0062] refer to Figure 5 In some embodiments, the diverter 34 includes a first air outlet 341 and a second air outlet 342, the first air outlet 341 is connected to the air duct 33, the second air outlet 342 is connected to the accommodating space 11, and the second air outlet 342 is used to dissipate heat for the bottom wall of the inner liner 2. In this way, the cold air is diverted through the first air outlet 341 and the second air outlet 342, and the bottom and the side of the inner liner 2 can be dissipated at the same time, so that the bottom of the inner liner 2 is kept at a low temperature, so that the cold air is not easy to heat up in the cold air channel, thereby improving the heat dissipation effect and heat dissipation efficiency of the cold air and reducing the overall temperature rise of the inner liner 2.

[0063] Exemplarily, the top wall of the diverter 34 is connected to a fixing bracket, and the fixing bracket is used to fix the diverter 34 to the bottom wall of the inner tank 2.

[0064] Exemplarily, the first air outlet 341 is circular and matches the air duct 33. The second air outlet 342 is square. Exemplarily, the first air outlet 341 and the second air outlet 342 are both arranged on a side of the diverter 34 facing away from the heat dissipation fan 32.

[0065] In other embodiments, the directions of the first air outlet 341 and the second air outlet 342 may be different, for example, the second air outlet 342 is disposed on the top wall of the diverter 34. This allows the cold air to flow directly toward the bottom wall of the inner container 2, making it easier to cool the bottom wall.

[0066] In other embodiments, there may be multiple first air outlets 341 , and each first air outlet 341 is correspondingly installed in one air guide duct 33 .

[0067] In some embodiments, the heat dissipation fan 32 is a negative pressure fan. The negative pressure fan has the characteristics of high efficiency, can generate a high negative pressure in a short time, quickly realize air convection, and facilitate the inhalation of external cold air. Secondly, the negative pressure fan has a compact structure and is easy to install, and can be arranged and adjusted according to actual needs.

[0068] In other embodiments, the heat dissipation fan 32 may also be other types of fans.

[0069] The technical features of the embodiments disclosed above can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the embodiments described above 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.

[0070] In the embodiments disclosed above, unless otherwise clearly specified and limited, the execution order of each step is not limited, for example, it can be executed in parallel, or it can be executed successively in different orders.
