Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and in particular to a fan assembly, a steam condensing device and a cooking device. Background Art

[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 excessive air pressure in the cooking cavity and potential safety hazards. In order to cool the discharged steam, a condensation component and a heat dissipation fan are usually arranged outside the cooking cavity in the prior art. The condensation component has a condensation channel for condensing steam. The air inlet end of the condensation channel is connected to the cooking cavity, and the air outlet end of the condensation channel is connected to a water box or other condensed water collection structure. The heat dissipation fan guides the cooling airflow to dissipate heat in the condensation channel to dissipate heat and cool the condensation component, thereby ensuring the condensation effect of the condensation component.

[0004] As the steam is gradually cooled down when passing through the condenser, the temperature of the condenser at the steam inlet end is higher, while the temperature at the outlet end is relatively lower, so that the heat dissipation demand of the condenser at the steam inlet end is larger, while the heat dissipation demand at the outlet end is relatively smaller; at the same time, different structural forms of condenser components will also lead to different heat dissipation requirements at different parts of the condenser component. The existing heat dissipation fan and condenser component are matched in a way that the cooling airflow guided by the heat dissipation fan flows roughly evenly to various parts of the condenser, which is difficult to meet the heat dissipation requirements of different parts of the condenser component, which may cause insufficient heat dissipation in areas with large heat dissipation requirements or waste of cooling capacity in the lower part with relatively small heat dissipation requirements, which is not conducive to improving the heat dissipation effect.

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

[0053] like Figures 1 to 5 As shown, this embodiment provides a cooking device that can use hot steam to cook food while achieving condensation and cooling of the hot steam, and improves the condensation and cooling effect of the hot steam, thereby improving the user experience 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.

[0054] The cooking device includes a body, a steam cooking module, a steam condensing device 100 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 condensing heat dissipation device is arranged on the outside of the inner tank component 200 and is used to condense and cool the steam to reduce the emission of hot steam; the controller is communicatively connected with the steam cooking module to control the operation of the cooking device.

[0055] The steam condensation device 100 includes a fan assembly 1 and a condensation assembly 2, wherein the condensation assembly 2 has a condensation channel, which extends from an air inlet end to an air outlet end along a first direction, and the air inlet end of the condensation channel is connected to a cooking cavity, so that hot steam in the cooking cavity can be passed into the condensation channel and discharged after being cooled through the condensation channel. The fan assembly 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 which are sequentially connected along the air flow direction, and the length direction of the air outlet extends along the first direction; the impeller 12 is installed in the air cavity, and an air outlet channel 134 is formed between the impeller 12 and the air outlet; the drive motor 11 is installed in the hood 13 and connected to the impeller 12, and the extension direction of the air outlet channel 134 intersects with the axial direction of the motor shaft of the drive motor 11. The condensation assembly 2 is arranged directly opposite to the air outlet. That is, when the impeller 12 rotates, the external cooling airflow is blown to the condensation component 2 through the air inlet 1311, the air cavity and the air outlet in sequence to dissipate the heat of the condensation component 2, thereby ensuring the condensation and cooling effect of the condensation component 2 on the hot steam.

[0056] In this embodiment, the fan assembly 1 also includes an adjustment assembly 3, which includes a diverter 31. The first end of the diverter 31 is rotatably installed in the air outlet channel 134 and the rotation axis is consistent with the axial direction of the motor shaft. The second end of the diverter 31 extends in the direction toward the air outlet to adjust the air volume distribution of the air outlet in the first direction when the impeller 12 is running.

[0057] The fan assembly 1 provided in this embodiment can adjust the air flow rate at various locations of the air outlet by setting an adjustment assembly 3 in the air outlet channel 134, so that the air flow rate at various locations of the air outlet can be reasonably matched according to the heat dissipation requirements of the condensation assembly 2 at various locations, so that the fan assembly 1 can better meet the different heat dissipation requirements of the condensation assembly 2, improve the applicability of the fan assembly 1 to different heat dissipation requirements, and improve the flexibility of use of the fan assembly 1.

[0058] The steam condensation device 100 provided in this embodiment adopts the above-mentioned fan assembly 1, so that the air flow rate at each air outlet of the fan assembly 1 can be adjusted according to the heat dissipation requirements of each part of the condensation assembly 2, thereby improving the condensation heat dissipation effect of the fan assembly 1 on the condensation assembly 2, and then improving the condensation cooling effect of the condensation assembly 2, and improving the condensation cooling effect of the steam condensation device 100 on the steam.

[0059] The cooking device provided in this embodiment can improve the steam condensation effect and enhance the user experience of the cooking device by adopting the above-mentioned steam condensation device 100.

[0060] Specifically, the diverter 31 extends from the outer side of the impeller 12 to the air outlet, and the diverter 31 divides the air outlet channel 134 into at least two sub-channels 1341 arranged side by side in a first direction. The rotation of the diverter 31 adjusts the width of the air outlet ends of two adjacent sub-channels 1341 in the first direction, thereby adjusting the air flow distribution at the air outlet.

[0061] In this embodiment, only one flow divider 31 is provided, that is, the air outlet channel 134 is divided into two sub-channels 1341 by the flow divider 31, which has a simple structure, is easy to set up, and has a low cost. In other embodiments, two or more flow dividers 31 may be provided at intervals along the first direction, and sub-channels 1341 are formed between two adjacent flow dividers 31 and between the channel wall of the air outlet channel 134 and the adjacent flow dividers 31.

[0062] In this embodiment, the first direction is the vertical direction, 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 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, improve the compactness of the structure, and reduce the overall footprint of the condensation heat dissipation device.

[0063] In this embodiment, a limiting structure 33 is provided in the air outlet channel 134, and the limiting structure 33 limits the rotation of the diverter 31 between the first position and the second position. This arrangement is conducive to limiting the movable stroke of the diverter 31, thereby preventing the diverter 31 from rotating to contact the channel wall of the air outlet channel 134 and causing damage to the diverter 31 or the wind cover 13. At the same time, it also prevents the diverter 31 from contacting the channel wall of the air outlet channel 134 and causing part of the sub-channel 1341 to be blocked, thereby causing the problem of poor air outlet.

[0064] Specifically, when the diverter 31 is in the first position, the second end of the diverter 31 and the upper end of the air outlet have a first spacing d1 in the vertical direction, and when the diverter 31 is in the second position, the diverter 31 and the upper end of the air outlet have a second spacing d2 in the vertical direction, d1<d2. For the convenience of subsequent description, the subchannel 1341 on the upper side of the diverter 31 is called the first subchannel 1341a, and the subchannel 1341 on the lower side of the diverter 31 is called the second subchannel 1341b.

[0065] Since the distance between the first end of the flow divider 31 and the channel wall of the air outlet channel 134 will not change with the rotation of the flow divider 31, that is, under the premise that the rotation speed of the impeller 12 remains unchanged, the air inlet flow of the two sub-channels 1341 remains approximately unchanged. When the flow divider 31 is in the first position, the width of the air outlet end of the first sub-channel 1341a is small, and the cooling airflow flowing out of the first sub-channel 1341a is more concentrated on the upper part of the condensation component 2, while the air outlet end of the second sub-channel 1341b is relatively wide, and the air outlet distribution range at the air outlet corresponding to the second sub-channel 1341b is larger and larger, and the average flow rate at each location is smaller than the flow rate at each location corresponding to the first sub-channel 1341a; when the flow divider 31 rotates from the first position to the second position, the distance between the flow divider 31 and the upper end of the air outlet increases, so that the airflow in the first sub-channel 1341a is more dispersed at the air outlet, while the airflow in the second sub-channel 1341b is relatively concentrated at the air outlet, thereby adjusting the airflow flow distribution at each location of the air outlet.

[0066] In the present embodiment, the wind hood 13 adopts a volute structure, that is, the cross-sectional area of ​​at least a part of the air outlet channel 134 gradually increases in the direction toward the air outlet, so as to facilitate the coordination between the wind hood 13 and the condensation component 2 while ensuring that the fan component 1 has sufficient air inlet flow, thereby improving the heat dissipation effect of the fan component 1 on the condensation component 2; at the same time, the wind hood 13 with a volute structure can reduce the noise of the impeller 12 during operation and reduce the kinetic energy loss of the fan component 1.

[0067] The wind cover 13 includes two end plates 131 spaced apart along the axial direction of the motor shaft of the driving motor 11 and a side panel 132 connected between the edges of the two end plates 131. An air inlet 1311 is provided on one end plate 131, and the side panel 132 has two ends spaced apart in the circumferential direction, and an air outlet is formed between the two ends.

[0068] 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.

[0069] Further, the side panel 132 includes a first channel wall 1321 and a second channel wall 1322 that are arranged opposite to each other and spaced apart in the first direction, and an arc-shaped panel portion 1323 connected between the first channel wall 1321 and the second channel wall 1322, a snail tongue is formed at the connection between the second channel wall 1322 and the arc-shaped panel portion 1323, the first channel wall 1321 and the arc-shaped panel portion 1323 are smoothly connected, and an air outlet is formed between one end of the first channel wall 1321 and the second channel wall 1322 away from the arc-shaped edge portion. That is, the first channel wall 1321 and the second channel wall 1322 form the channel walls on opposite sides of the air outlet channel 134.

[0070] The second channel wall 1322 includes an inclined section, the first end of which is connected to the arc-shaped enclosure portion 1323 to form a volute tongue, and the other end of the inclined section extends in a direction away from the volute tongue and away from the first channel wall 1321, so that the wind channel 134 is at least partially expanded along the airflow direction. The second channel wall 1322 also includes an extension section connected to the second end of the inclined section, and the extension section is parallel to and spaced from the first channel wall 1321, so as to facilitate the coordination between the wind cover 13 and the condensing assembly 2.

[0071] In this embodiment, when the diverter 31 is in the first position, the first channel wall 1321 and the diverter 31 are arranged in parallel or the diverter 31 extends from the first end to the second end in a direction away from the first channel wall 1321, and the angle between the extension direction of the first channel wall 1321 and the extension direction of the diverter 31 is less than 6°. This arrangement enables the cross-sectional area of ​​the air inlet end of the first sub-channel 1341a to be equal to the cross-sectional area of ​​the air outlet end when the diverter 31 is in the first position, or the cross-sectional area of ​​the air outlet end is slightly larger than the cross-sectional area of ​​the air inlet end, so that the airflow thrown out by the impeller 12 can flow more concentratedly in the sub-channel 1341 without affecting the flow smoothness. That is, this arrangement enables the airflow density at the air outlet end of the first sub-channel 1341a to reach the most concentrated level when the diverter 31 is in the first position.

[0072] When the diverter 31 is in the second position, the angle between the extension direction of the diverter 31 and the extension direction of the inclined section is less than 6°, so that the diverter 31 will not hinder the flow of air, and the air outlet end of the first sub-channel 1341a can reach a larger width, so that the air outlet flow density in the first direction is relatively uniform.

[0073] Furthermore, the minimum spacing between the first channel wall 1321 and the inclined section is W0, that is, the length of one end of the air outlet channel 134 close to the impeller 12 in the first direction is W0, and the spacing between the rotation axis of the flow divider 31 and the first channel wall 1321 is W1, 0.35W0≤W1≤0.5W0. This setting can avoid the problem of poor flow distribution adjustment effect caused by too small or too large width of W0.

[0074] In this embodiment, the distance between one end of the diverter 31 and the outer contour circle of the impeller 12 is greater than zero and less than or equal to 30 mm, thereby improving the separation effect of the diverter 31 on the air outlet channel 134 .

[0075] In this embodiment, the limiting structure 33 includes two limiting protrusions 331 protruding from the air outlet channel 134. The two limiting protrusions 331 are arranged at intervals along the rotation direction of the diverter 31, and the diverter 31 rotates between the two limiting protrusions 331. Of the two limiting protrusions 331, the one close to the air outlet is the first limiting protrusion 331a, and the other is the second limiting protrusion 331b. When the diverter 31 is in the first position, the diverter 31 abuts against the first limiting protrusion 331a, and when the diverter 31 is in the second position, the diverter 31 abuts against the second limiting protrusion 331b. By setting the limiting protrusion 331 to limit the rotation stroke of the diverter 31, the structure is simple and easy to implement.

[0076] In other embodiments, the limiting structure 33 may adopt other structures, for example, an arc-shaped groove is opened on the channel wall of the air outlet channel 134, a guide portion is provided on the diverter 31, the guide portion is slidably set in the arc-shaped groove, and the guide portion is abutted against the groove walls at both ends of the arc-shaped groove to achieve rotation limitation of the diverter 31.

[0077] The length of the diverter 31 along its extension direction is L0, and the spacing between the limiting protrusion 331 and the rotation axis of the diverter 31 is L1, 0.8L0≤L1≤0.95L0, so that the portion of the diverter 31 close to the second end abuts against the limiting protrusion 331, thereby improving the limiting effect of the limiting protrusion 331 and the diverter 31. Further, the spacing between the first limiting protrusion 331a and the air outlet is less than or equal to 50 mm, and more preferably less than or equal to 20 mm.

[0078] Furthermore, the adjustment assembly 3 includes a flow divider drive 32, which is mounted on the hood 13 and connected to the flow divider 31, and drives the flow divider 31 to rotate. The flow divider drive 32 is communicatively connected to the controller of the cooking device, so that the controller can control the operation of the flow divider drive 32, thereby controlling the position of the flow divider 31.

[0079] The flow splitter driving member 32 includes a motor, the motor housing of which is installed outside the wind shield 13, and the driving shaft of the flow splitter driving member 32 rotates and seals through the wind shield 13 and is connected to the flow splitter 31, thereby reducing the occupation of the internal space of the air outlet channel 134 by the adjustment component 3, thereby avoiding the influence of the setting of the adjustment component 3 on the air intake flow of the fan component 1. In this embodiment, the motor is installed on the side of the wind shield 13 where the air inlet 1311 is provided, so as to facilitate the installation of the fan component 1 on the liner component 200.

[0080] In this embodiment, in order to control the operation of the diversion drive 32, the cooking device also includes a temperature detection component 5, which detects the temperature of the gas discharged from the condensation channel, and the temperature detection component 5 is communicatively connected to the controller; and / or, the cooking device includes a flow meter, which detects the steam intake air flow rate of the condensation channel, and the flow meter is communicatively connected to the controller.

Therefore, when the user uses the cooking device, the position of the target diverter 31 can be obtained according to the steam discharge flow detected during the cooking process and the steam discharge flow-diverter 31 position relationship table built into the controller, and then the motor can be controlled to operate to adjust the diverter 31 to the target diverting position, thereby improving the automation of the adjustment and enhancing the user experience of the cooking device.

[0082] 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 is located in 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 in turn.

[0083] The inner tank assembly 200 includes an inner tank 201 and an air duct bracket 202 disposed at the rear side of the inner tank 201.

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, thereby ensuring the condensation and cooling effect of the condensation heat dissipation device on the hot steam.

[0084] In this embodiment, the condensation and heat dissipation device 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 while avoiding the condensation and heat dissipation device occupying the left and right sides of the inner tank assembly 200, reducing the size of the cooking equipment in the left and right directions, thereby facilitating the miniaturization of the cooking equipment.

[0085] The cooking device also includes an electric heating element and a turbulent fan blade 14, so that the electric heating element can heat the cooking cavity and promote the circulation of hot air in the cooking cavity through the turbulent fan blade 14, thereby achieving the function of baking food in the cooking cavity.

[0086] Specifically, a hot air cavity is formed between the air duct bracket 202 and the inner pot 201, and the inner pot 201 is provided with a plurality of air flow holes communicating with the hot air cavity, and the electric heating element and the spoiler blades 14 are both installed in the hot air cavity.

[0087] It is worth noting that the matching structure of the air duct support 202 and the inner pot 201, the specific structure of the machine body and the steam cooking module can be set with reference to the existing technology. This is not the focus of this embodiment and will not be repeated here.

[0088] 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 sections 221 connected by bending sections 222 from top to bottom. The extension direction of the condensation section 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.

[0089] In this embodiment, the arrangement density of the condensation sections 221 gradually decreases from the air inlet end to the air outlet end, so that the upper part of the condenser tube 22 has a stronger condensation effect on the hot steam, and at the same time cooperates with a better heat dissipation effect, effectively improving the overall condensation effect of the condenser tube 22 on the hot steam. In other embodiments, the condenser tube 22 includes a plurality of condensation sections arranged in sequence from the air inlet end to the air outlet end, each condensation section includes a plurality of condensation sections 221, the condensation sections are arranged in a one-to-one correspondence with the sub-air ducts, 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 air outlet end.

[0090] The condensation assembly 2 further includes a radiator 21, which is installed at the air outlet 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, and all the condensation sections 221 are located in the air outlet path of the air outlet 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.

[0091] 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.

[0092] 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 through the gap between the two condensation sections 221 of the condensation tube 22 on the side close to the air outlet, 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.

[0093] 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, and further improving the condensation effect of the condensation assembly 2.

[0094] Specifically, the radiator 21 includes a first mounting plate 212 and a second mounting plate 213 that are opposite and spaced apart, and all the heat dissipation fins 211 are located between the first mounting plate 212 and the second mounting plate 213.

[0095] 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 groove 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. 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.

[0096] 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, thereby better ensuring the connection stability between the hood 13 and the radiator 21. Preferably, a plurality of fasteners are arranged opposite to and spaced apart from each other along the extending direction of the positioning edge 2121.

[0097] Furthermore, in the projection plane where the air outlet 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, 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.

[0098] In order to improve the convenience of condensed water recovery, the condensation heat dissipation device also includes a water receiving 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 opened on the upper side of the water receiving box 4 to facilitate the discharge of gas in the water receiving box 4 and avoid excessive air pressure in the water receiving box 4. An overflow pipe is preferably provided at the overflow hole to facilitate the control of the exhaust position.

[0099] The temperature detection member 5 is installed on the upper part of the water receiving box 4 , thereby being able to detect the exhaust gas temperature discharged from the condensation channel while improving the installation convenience of the temperature detection member 5 .

[0100] 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 receiving box 4 is connected to the inner cavity of the water tank 300 through the drain pipe 7, so that the condensed water discharged from the water receiving 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 receiving box 4 for cleaning. A drain valve is provided on the drain pipe 7 to control the discharge of the condensed water in the water receiving box 4 into the water tank 300.
