Description

Technical Field

[0002] As people's living standards improve, automatic cooking equipment such as electric steamers and steam ovens are being used more and more widely in family life, improving users' flexibility in choosing cooking methods and life experience.

[0003] Cooking equipment with steam cooking function achieves cooking by introducing high-temperature steam into the cooking cavity. During the cooking process, the steam in the cooking cavity needs to be discharged to the outside to avoid safety hazards caused by excessive air pressure in the cooking cavity. In order to cool the discharged steam, a condenser and a heat dissipation fan are usually arranged outside the cooking cavity in the prior art. The air inlet end of the condenser is connected to the cooking cavity, and the exhaust end of the condenser is connected to a water box or other condensed water collection structure. The heat dissipation fan guides the cooling airflow to dissipate heat from the condenser to dissipate heat and cool the condenser, thereby ensuring the condensation effect of the condenser.

[0004] In order to ensure the condensation effect of the condenser tube, the existing condenser tube is usually bent and arranged in a serpentine shape to increase the length of the condenser tube. Since the steam is gradually cooled when flowing through the condenser tube, the temperature of the condenser tube at the steam inlet end is higher, while the temperature at the exhaust end is relatively lower, so that the heat dissipation demand of the condenser tube at the steam inlet end is larger, and the existing arrangement of the heat dissipation fan and the condenser tube makes the cooling airflow guided by the heat dissipation fan flow roughly evenly to all parts of the condenser tube, resulting in insufficient heat dissipation near the inlet end of the condenser tube and waste of cold near the exhaust end, which is not conducive to improving the condensation and cooling effect.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] like Figures 1 to 3 As shown, this embodiment provides a cooking device, which includes a body, a steam cooking module and a controller, wherein the body has a cooking cavity with an open front side, the steam cooking module is used to provide hot steam into the cooking cavity, so as to use the hot steam to cook the food in the cooking cavity; the controller is communicatively connected with the steam cooking module to control the operation of the cooking device. The cooking device can be, but is not limited to, an electric steamer, a steam oven, or a microwave oven with steam cooking function.

[0045] To achieve condensation and cooling of the steam, in this embodiment, the cooking device further includes a condensation and heat dissipation device 100, which is disposed on the outside of the inner pot assembly 200 and is used to condense and cool the steam to reduce the emission of hot steam.

[0046] Specifically, the condensation heat dissipation device 100 includes a condensation component 2, a heat dissipation component 1 and a guide component 3. The condensation component 2 has a condensation channel, which extends from the air inlet end to the exhaust end along the first direction; the heat dissipation component 1 includes a hood 13, an impeller 12 and a drive motor 11, the hood 13 has an air inlet 1311, an air cavity and an air outlet 135 which are sequentially fluidly connected along the fluid flow direction, the condensation component 2 is arranged at the air outlet 135, the impeller 12 is located in the air cavity, the drive motor 11 is installed on the hood 13 and connected to the impeller 12, and an air outlet channel 134 is formed between the impeller 12 and the air outlet 135; the guide component 3 is arranged in the air outlet channel 134 and divides the air outlet channel 134 into at least two sub-air ducts 1341, and the air outlet ends of all the sub-air ducts 1341 are sequentially arranged along the first direction. When the impeller 12 is running, the air volume of all the sub-air ducts 1341 gradually increases in the direction away from the exhaust end.

[0047] The condensation heat dissipation device 100 provided in the present embodiment provides a guide component 3 in the air outlet channel 134 and divides the air outlet channel 134 into a plurality of sub-air channels 1341 through the guide component 3, so that the guide component 3 can guide the air flow to different positions of the air outlet 135, and control the air volume of each sub-air channel 1341, so as to achieve the purpose that the air volume at the position close to the air inlet end of the condensation channel is relatively large, and the air volume at the position far from the air inlet end of the condensation component 2 is relatively small, so that the condensation component 2 has a larger cooling airflow in the area with greater heat dissipation demand Flow rate, enhancing the condensation and cooling effect of the condensation channel on the steam, while a relatively small air flow rate is configured for the area with relatively small heat dissipation demand, so as to reduce the waste of cold air, thereby improving the heat dissipation effect of the heat dissipation component 1 on the condensation component 2 as a whole, and improving the condensation and cooling effect of the condensation component 2 on the hot steam; at the same time, by arranging the guide component 3 in the air outlet channel 134 to achieve the distribution of the air volume, it is possible to reduce the improvement cost of the condensation heat dissipation device 100, avoid the problem of increasing the size requirement of the heat dissipation component 1 due to the arrangement of the guide component 3, and improve the structural compactness of the condensation heat dissipation device 100.

[0048] The cooking device provided in this embodiment can improve the condensation and cooling effect of the condensation and heat dissipation device 100 on hot steam by adopting the above-mentioned condensation and heat dissipation device 100, thereby reducing the steam emission amount and steam emission temperature, and improving the user experience of the cooking device.

[0049] In this embodiment, the machine body includes an inner tank assembly 200, a base 400 installed under the inner tank assembly 200 and a casing surrounding the outer side of the inner tank assembly 200. The inner tank assembly 200 has a cooking cavity, and the condensation and heat dissipation device 100 is located between the inner tank assembly 200 and the casing assembly. A cold air inlet is provided on the machine body. When the impeller 12 is running, the cooling air flow outside the cooking equipment enters into the space between the inner tank assembly 200 and the casing through the cold air inlet, and is blown toward the condensation assembly 2 through the air inlet 1311, the air cavity and the air outlet 135 in turn.

[0050] The inner tank assembly 200 includes an inner tank 201 and an air duct bracket 202 arranged at the rear side of the inner tank 201. A steam outlet is provided on the inner tank 201, and a steam exhaust port is provided on the air duct bracket 202. The steam exhaust port is connected to the steam outlet, and the steam exhaust port is connected to the air inlet end of the condensation channel. The condensation heat dissipation device 100 is installed on the side of the air duct bracket 202 away from the inner tank 201 to improve the installation and disassembly convenience of the condensation heat dissipation device 100. The air duct bracket 202 is fastened to the inner tank 201 and / or the casing. Furthermore, a partition cavity is provided inside the air duct bracket 202, and the partition cavity is used to reduce the heat dissipation from the inner tank 201 to the condensation heat dissipation device 100, thereby ensuring the condensation and cooling effect of the condensation heat dissipation device 100 on the hot steam.

[0051] In this embodiment, the condensation and heat dissipation device 100 is installed on the back side of the inner tank assembly 200, which is beneficial to ensure the installation space of the condensation and heat dissipation device 100 while avoiding the condensation and heat dissipation device 100 occupying the left and right sides of the inner tank assembly 200, reducing the size of the cooking device in the left and right directions, thereby facilitating the miniaturization of the cooking device.

[0052] It is worth noting that the specific structure of the machine body and the steam cooking module can be set with reference to the prior art. This is not the focus of this embodiment and will not be described in detail here.

[0053] In this embodiment, the length of the outlet ends of all sub-air ducts 1341 in the first direction gradually increases in the direction away from the exhaust end of the condensation channel, thereby making the air flow rate entering the upper sub-air duct 1341 greater than the air flow rate entering the lower sub-air duct 1341, thereby improving the reliability of air flow control. In other embodiments, the air inlet area of ​​the air inlet ends of all sub-air ducts 1341 may also gradually increase in the first direction away from the exhaust end of the condensation channel.

[0054] In this embodiment, the guide assembly 3 includes a guide plate 31, which extends from the impeller 12 to the air outlet 135. At least two guide plates 31 are arranged at intervals, and sub-air ducts 1341 are formed between two adjacent guide plates 31 and between the guide plate 31 and the channel wall of the air outlet channel 134 and two adjacent guide plates 31. This structural arrangement of the guide assembly 3 can simplify the structure of the guide assembly 3 while realizing the arrangement of multiple sub-air ducts 1341, and reduce the processing difficulty of the guide assembly 3. In this embodiment, two guide plates 31 are arranged, thereby forming three sub-air ducts 1341.

[0055] In another embodiment, one guide plate 31 is provided, and sub-air channels 1341 are respectively formed between the guide plate 31 and the channel walls on opposite sides of the air outlet channel 134. In another embodiment, three or other numbers of guide plates 31 may be provided. The number of guide plates 31 may be specifically set according to the size of the air outlet channel 134.

[0056] In this embodiment, the first direction is the vertical direction, that is, the condensation channel extends from top to bottom, and the upper end of the condensation channel is the air inlet end, so that the condensed water formed by the condensation of hot steam in the condensation channel can drip downward under the action of gravity, ensuring the smoothness of the condensed water discharge. The heat dissipation component 1 and the condensation component 2 are arranged side by side in a horizontal direction to improve the local rationality of the structure of the condensation heat dissipation device 100, improve the compactness of the structure, and reduce the overall footprint of the condensation heat dissipation device 100.

[0057] An air inlet 1311 is provided on one side of the air hood 13 away from the inner tank assembly 200, the impeller 12 is arranged opposite to the air inlet 1311, the air outlet 135 is located at the radial side of the impeller 12, and the axial direction of the impeller 12 is perpendicular to the parallel direction of the heat dissipation assembly 1 and the condensation assembly 2, thereby making the overall structure of the condensation heat dissipation device 100 more compact. That is, in this embodiment, the heat dissipation assembly 1 and the condensation assembly 2 are arranged side by side in the left-right direction, and the axial direction of the impeller 12 is the front-back direction.

[0058] In this embodiment, the wind shield 13 has two end plates 131 arranged opposite to each other in the axial direction of the impeller 12, and the two ends of the guide plate 31 are respectively connected to the two end plates 131 to ensure that two adjacent sub-air ducts 1341 can be separated and arranged in the first direction; at the same time, this arrangement is also conducive to the arrangement of the guide assembly 3 in the wind shield 13, and improves the installation convenience of the wind shield 13 on the liner assembly 200. The wind shield 13 also includes a side panel 132 connected between the edges of the two end plates 131, and the side panel 132 has two ends arranged opposite to each other in the circumferential direction, and an air outlet 135 is formed between the two ends.

[0059] In other embodiments, the wind cover 13 may include an end plate 131 and a side panel 132 arranged at the edge of the end plate 131, and the side panel 132 abuts against the inner liner assembly 200 so that the end plate 131, the side panel and the inner liner assembly 200 together form an air cavity, one side of the guide plate 31 abuts against the end plate 131, and the other side of the guide plate 31 abuts against the inner liner assembly 200.

[0060] The wind shield 13 also includes a motor mounting portion 133 disposed at the air inlet 1311, the motor mounting portion 133 includes a mounting ring portion 1331 coaxial with the air inlet 1311 and spaced apart, and a connecting arm portion 1332 connected between the mounting ring portion 1331 and the end plate 131, the mounting ring portion 1331 is spaced apart outside the end plate 131, and a plurality of connecting arm portions 1332 are spaced apart along the circumferential direction of the mounting ring portion 1331, the motor housing of the drive motor 11 is inserted into the mounting ring portion 1331 and fastened to the motor mounting portion 133. The structural arrangement of the motor mounting portion 133 is conducive to heat dissipation of the drive motor 11 and reduces the size of the wind shield 13 in the axial direction of the impeller 12.

[0061] The guide plate 31 and the wind shield 13 are preferably provided in one piece, so as to ensure the sealing of the connection between the guide plate 31 and the wind shield 13, thereby ensuring the guiding effect of the guide plate 31 on the airflow guided by the impeller 12, and ensuring the stability and reliability of the setting of the guide plate 31 in the wind shield 13. In other embodiments, the wind shield 13 and the guide plate 31 can also be provided in one piece.

[0062] Furthermore, in order to better guide the flow of cooling air, in the present embodiment, the cross-sectional area of ​​the air outlet channel 134 tends to gradually increase from the impeller 12 to the air outlet 135. This can ensure that the air outlet cross-section of the air outlet 135 is sufficient while reducing the size of the wind cover 13 at the end away from the air outlet 135, thereby reducing the overall footprint of the heat dissipation assembly 1. Such a setting can also increase the air outlet volume, thereby improving the cooling effect.

[0063] In this embodiment, the wind cover 13 is a volute structure, and the lowermost sub-air duct 1341 is arranged close to the volute tongue of the volute structure. By setting the wind cover 13 as a volute structure and setting the volute tongue at the lower side of the volute structure, the airflow thrown out by the impeller 12 is more concentrated at the upper part at the end of the air outlet channel 134 away from the air outlet 135, which is more conducive to guiding the airflow thrown out of the impeller 12 to flow into the sub-air duct 1341 located on the upper side, thereby increasing the airflow flow of the sub-air duct 1341 on the upper side.

[0064] That is, in this embodiment, the air outlet channel 134 has an upper channel wall and a lower channel wall that are arranged opposite to each other in the first direction, the upper channel wall is arranged horizontally, and the lower channel wall of the air outlet channel 134 has an inclined section that extends downwardly from the volute tongue to the air outlet 135, so as to increase the cross-sectional area of ​​the air outlet channel 134 along the air flow direction. Further, an extension section is connected to one end of the inclined section close to the air outlet 135, and the extension section extends horizontally in the direction toward the air outlet 135, and the extension section is parallel to the upper channel wall of the air outlet channel 134 and is arranged at intervals, so as to facilitate the coordination between the wind cover 13 and the condensation assembly 2; at the same time, the length of the air outlet channel 134 can be increased while making the inclined section have a suitable length.

[0065] The guide plate 31 has an air inlet end and an air outlet end which are arranged relatively, the air inlet end is arranged near the impeller 12, and the air outlet end is arranged near the air outlet 135. The guide plate 31 extends from top to bottom toward the air outlet 135. This arrangement makes the width of at least part of the sub-air ducts 1341 close to the impeller 12 relatively small, while the width of the sub-air ducts 1341 close to the air outlet 135 is relatively large, so that the arrangement of the guide plate 31 matches the overall shape of the air outlet channel 134, thereby improving the guiding effect of the guide plate 31 on the cooling airflow; at the same time, this arrangement makes the outlet width of the uppermost sub-air duct 1341 larger, while avoiding the problem that the inlet width of the lower sub-air duct 1341 is too small due to the small spacing between the lowermost guide plate 31 and the volute, thereby affecting the smoothness of the airflow, thereby ensuring the smoothness of the overall airflow.

[0066] Among two adjacent guide plates 31, the angle between the guide plate 31 located on the upper side and the horizontal direction is greater than the angle between the guide plate 31 located on the lower side and the horizontal direction, so that among two adjacent sub-air ducts 1341, the width of the air outlet 135 of the sub-air duct 1341 located on the upper side is greater than the width of the outlet end of the sub-air duct 1341 located on the lower side, so that the air flow rate of the upper sub-air duct 1341 is greater than the air flow rate of the lower sub-air duct 1341.

[0067] like Figure 1 and Figure 5 As shown, in this embodiment, the condensation component 2 includes a condensation tube 22, the inner cavity of the condensation tube 22 forms a condensation channel, and the condensation tube 22 includes a plurality of condensation segments 221 connected by bending segments 222 from top to bottom, and the extension direction of the condensation segment 221 is consistent with the thickness direction of the wind hood 13. Therefore, on the basis of keeping the size of the condensation component 2 in the height direction unchanged, the length of the condensation channel can be increased, thereby improving the condensation effect of the condensation tube 22 on hot steam.

[0068] In this embodiment, the arrangement density of the condensation section 221 gradually decreases from the air inlet end to the exhaust end, so that the upper part of the condenser tube 22 has a stronger condensation effect on the hot steam. At the same time, with better heat dissipation effect, the overall condensation effect of the condenser tube 22 on the hot steam is effectively improved.

[0069] In other embodiments, the condensation tube 22 includes a plurality of condensation sections arranged in sequence from the air inlet end to the exhaust end, each condensation section includes a plurality of condensation sections 221, the condensation sections are arranged in one-to-one correspondence with the sub-air ducts 1341, and the arrangement density of the condensation sections 221 in the same condensation section is consistent, and the arrangement density of the condensation sections 221 in the plurality of condensation sections gradually decreases from the air inlet end to the exhaust end.

[0070] The condensation assembly 2 further includes a radiator 21, which is installed at the air outlet 135 and includes a plurality of heat dissipation fins 211 arranged at intervals, a flow channel penetrating in the first direction is formed between two adjacent heat dissipation fins 211, all the flow channels are connected to the air outlet 135, and all the condensation sections 221 are located in the air outlet path of the air outlet 135 and pass through all the heat dissipation fins 211. Thus, the heat dissipation effect of the cooling airflow on the condensation tube 22 can be enhanced by setting the radiator 21.

[0071] At least two condensing tubes 22 are arranged side by side, thereby increasing the total length of the condensing channel while reducing the height of a single condensing tube 22, thereby reducing the overall size of the condensing assembly 2 and improving the compactness of the structure. The plurality of condensing tubes 22 are arranged at intervals along the arrangement direction of the condensing assembly 2 and the heat dissipation assembly 1.

[0072] Optionally, the condensation ends of two adjacent condensation tubes 22 are at least partially staggered in the first direction, so that the airflow can be better blown to the condensation section 221 away from the air outlet 135 through the gap between the two condensation sections 221 of the condensation tube 22 on the side close to the air outlet 135, thereby improving the heat dissipation effect of the cooling airflow on the condensation tube 22. The condensation sections 221 of two adjacent condensation sections 221 can also be arranged one by one in the first direction.

[0073] Furthermore, a positioning structure is provided between the condensation assembly 2 and the wind cover 13, and the positioning structure cooperates to position the condensation assembly 2 relative to the wind cover 13 in the first direction. This ensures the assembly accuracy of the condensation assembly 2 and the wind cover 13, thereby improving the flow guiding effect of the flow guiding assembly 3, and further improving the condensation effect of the condensation assembly 2.

[0074] Specifically, the radiator 21 includes a first mounting plate 212 and a second mounting plate 213 that are arranged oppositely and at intervals, and all the heat dissipation fins 211 are located between the first mounting plate 212 and the second mounting plate 213. The positioning structure includes a first positioning structure arranged on the fan cover 13 and a second positioning structure arranged on the first mounting plate 212, the second mounting plate 213 is connected to the liner assembly 200, and the first positioning structure cooperates with the second positioning structure for positioning.

[0075] The first positioning structure includes a positioning groove 1312 that is recessed toward the inner cavity to improve the positioning effect and reduce the processing difficulty of the first positioning structure. The positioning groove 1312 is formed by stamping the end plate 131, and the first mounting plate 212 has a positioning edge 2121 that extends out of the heat dissipation fin 211 in the direction toward the fan cover. The positioning edge 2121 is accommodated in the bottom of the positioning groove 1312, so that the radiator 21 can be installed and positioned on the fan cover through the cooperation of the positioning edge 2121 and the positioning groove 1312. At the same time, this arrangement can also prevent the first mounting plate 212 from protruding from the surface of the end plate 131, thereby improving the overall aesthetics of the condensing heat dissipation device 100.

[0076] In other embodiments, one of the first positioning structure and the second positioning structure may be protrudingly provided with a positioning protrusion, and the other may be provided with a positioning hole, and the positioning protrusion may be inserted into the positioning hole.

[0077] Furthermore, the first positioning edge 2121 is connected to the bottom of the positioning groove 1312 by a fastener, so that the first mounting plate 212 is fastened to the hood 13, and the connection stability between the hood 13 and the radiator 21 is better ensured. Preferably, a plurality of fasteners are arranged opposite to each other and at intervals along the extending direction of the positioning edge 2121.

[0078] Furthermore, in the projection plane where the air outlet 135 is located, the orthographic projections of all the heat dissipation fins 211 in the projection plane are located within the range of the orthographic projection of the fan cover in the projection plane. This makes the size of the radiator 21 more compatible with the size of the air outlet 135, while ensuring the cooling effect of the cooling airflow on the condensing assembly 2, reducing the space occupied by the condensing assembly 2 and reducing the cost of the condensing assembly 2.

[0079] In order to improve the convenience of condensed water recovery, the condensation heat dissipation device 100 further includes a water collecting box 4, which is located below the radiator 21 and has a condensed water cavity, and the lower end of the condensation tube 22 is connected to the condensed water cavity. As a result, the condensed water condensed in the condensation tube 22 can fall into the condensed water cavity under the action of gravity. An overflow hole is provided on the upper side of the water collecting box 4 to facilitate the discharge of gas in the water collecting box 4 and avoid excessive air pressure in the water collecting box 4.

[0080] In this embodiment, the steam cooking module includes a steam generator and a water tank 300. The water tank 300 is mounted on the base 400 and is used to supply water to the steam generator. The steam generator generates hot steam and supplies the hot steam to the inner pot 201. The water collecting box 4 is connected to the inner cavity of the water tank 300 through the drain pipe 5, so that the condensed water discharged from the water collecting box 4 can be discharged into the water tank 300 to achieve water reuse or facilitate the cleaning of the condensed water, thereby eliminating the need to remove the water collecting box 4 for cleaning. A drain valve is provided on the drain pipe 5 to control the discharge of the condensed water in the water collecting box 4 into the water tank 300.
