Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and in particular to a humidifier and a cooking appliance. Background Art

[0002] In the related art, the desktop micro-oven does not have a humidifier. When the desktop micro-oven is in a microwave mode, a single microwave mode or a single baking mode, the dehydration amount of the food is large, resulting in a dry taste of the food, which affects the cooking effect of the desktop micro-oven. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present application provides a humidifier.

[0005] A second aspect of the present application provides a cooking appliance.

[0006] In view of this, the present application provides a humidifier for cooking utensils, comprising: a humidifying body, the humidifying body is provided with a water inlet and an exhaust port, and at least one heat exchange channel is provided in the humidifying body; when the number of heat exchange channels is multiple, the multiple heat exchange channels are stacked, and any two adjacent heat exchange channels are connected; a first heating part, provided in the humidifying body, each heat exchange channel is connected to the first heating part; wherein, among the multiple heat exchange channels, a heat exchange channel located at the end is connected to any one of the water inlet and the exhaust port.

[0007] A humidifier provided in the present application includes a humidifying body and a first heating part.

[0008] The humidifying body is provided with a water inlet and an exhaust port, and at least one heat exchange channel is provided in the humidifying body. When the number of heat exchange channels is multiple, the multiple heat exchange channels are stacked. Among the multiple heat exchange channels, a heat exchange channel located at the end is connected to the water inlet, and the heat exchange channel is also connected to the exhaust port. Any two adjacent heat exchange channels among the multiple heat exchange channels are connected.

[0009] When the humidifier is working, water enters the humidifier through the water inlet, and then falls into the heat exchange channel arranged adjacent to the water inlet under the action of gravity, and flows downward through the multiple heat exchange channels in sequence along the direction in which the multiple heat exchange channels are superimposed. Since any of the multiple heat exchange channels is connected to the first heating part, the heat generated by the operation of the first heating part can be transferred to the multiple heat exchange channels, and the water flow will fully absorb the heat at the heat exchange channel and be completely vaporized when flowing along the heat exchange channel. That is, when the water flow flows through the heat exchange channel, a vapor-liquid phase change will occur to form water vapor. The vaporized water vapor will move upward (i.e., in the direction opposite to the direction of gravity), and then spray into the cooking cavity of the cooking utensil through the exhaust port, so as to achieve the purpose of moisturizing the food in the cooking cavity, and can adjust the moisture content in the cooking cavity, prevent the food from drying out when the cooking utensil is cooking (e.g., the cooking utensil is in a micro-roasting mode, a single microwave mode, or a single baking mode), which is conducive to improving the cooking effect of the cooking utensil. This setting can also be used in combination with the self-cleaning mode of the cooking appliance. For example, when the cooking cavity is self-cleaning, the steam sprayed by the humidifier can dry and sterilize the cooking cavity at high temperature.

[0010] It can be understood that each heat exchange channel is connected to the first heating part, and any two adjacent heat exchange channels among the multiple heat exchange channels are connected, so the water flow will flow through the multiple heat exchange channels in sequence under the action of gravity, that is, the water flow will exchange heat with the multiple heat exchange channels in sequence. This arrangement enables the humidifier to have a larger effective heat exchange area, greatly increases the heating surface area of ​​the first heating part, maximizes the heating effect under unit power, and can quickly heat water.

[0011] It is understandable that the vaporized water vapor will flow upward through multiple heat exchange channels in sequence, and then flow to the exhaust port. When the water vapor flows through multiple heat exchange channels, the heat at the heat exchange channels can effectively prevent the newly formed water vapor from condensing, and can achieve rapid and maximum steam output, which is beneficial to improving the working efficiency of the humidifier and reducing the energy consumption of the humidifier.

[0012] The humidifier described above in this application may also have the following additional technical features:

[0013] In some embodiments, optionally, the humidification body includes: a shell, the shell is provided with a water inlet and an exhaust port, and the first heating part is arranged in the shell; a heat sink, the heat sink is connected between the first heating part and the inner surface of the shell, and the heat sink and the inner surface of the shell enclose a heat exchange channel.

[0014] In this embodiment, the structure of the humidifying body is further defined so that the humidifying body includes a shell and a heat sink.

[0015] The first heating part and the heat sink are both located in the shell.

[0016] The shell is provided with a water inlet and an exhaust port.

[0017] The heat sink is connected to the outer surface of the first heating portion and the inner surface of the shell, and the heat sink and the inner surface of the shell enclose at least one heat exchange channel.

[0018] Since the heat sink is connected to the first heating part, the heat sink has the function of increasing the heating area of ​​the first heating part, so that water at different positions of the heat exchange channel can effectively contact the heat. This is beneficial to improving the heat exchange efficiency, facilitating rapid and maximum steam release, and effectively preventing the condensation of newly formed water vapor.

[0019] It can be understood that the first portion of the outer edge of the heat sink is connected to the first heating portion, and the second portion of the outer edge of the heat sink is connected to the inner surface of the shell.

[0020] In some embodiments, optionally, when the number of heat exchange channels is multiple, the heat sink includes: a spiral fin, the spiral fin having a first outer edge and a second outer edge that are relatively arranged, the first outer edge is connected to the first heating part, and the second outer edge is connected to the inner surface of the shell; wherein the spiral fin extends along the overlapping direction of the multiple heat exchange channels.

[0021] In this embodiment, the structure of the heat sink is further defined so that the heat sink includes a spiral fin having a first outer edge and a second outer edge, the first outer edge and the second outer edge are arranged opposite to each other, the first outer edge is connected to the first heating part, and the second outer edge is connected to the inner surface of the shell.

[0022] The spiral fins extend along the stacking direction of the multiple heat exchange channels. The extension direction of the spiral fins determines the extension shape of the multiple heat exchange channels formed. That is, the multiple heat exchange channels are connected in sequence to form a spiral channel structure, and water will flow along the spiral channel structure. The water flow will fully absorb the heat generated by the operation of the first heating part, which can ensure the efficiency of vaporization and provide structural support for rapid and large-scale steam output.

[0023] In some embodiments, optionally, when the number of heat exchange channels is multiple, the heat sink includes: a plurality of annular heat sinks, the plurality of annular heat sinks are arranged at intervals along the stacking direction of the plurality of heat exchange channels, the inner peripheral wall of the annular heat sink is connected to the first heating part, and the outer peripheral wall of the annular heat sink is connected to the inner surface of the shell; wherein each annular heat sink is provided with a through hole, and the through holes of any two adjacent annular heat sinks are staggered.

[0024] In this embodiment, the structure of the heat sink is further defined such that the heat sink includes a plurality of annular heat sinks.

[0025] Any of the plurality of annular heat sinks has an inner peripheral wall and an outer peripheral wall, the inner peripheral wall of the annular heat sink is connected to the outer surface of the first heating portion, and the outer peripheral wall of the annular heat sink is connected to the inner surface of the shell.

[0026] Along the stacking direction of the multiple heat exchange channels, multiple annular radiating fins are arranged at intervals.

[0027] A plurality of annular heat sinks and the inner surface of the shell enclose a plurality of heat exchange channels.

[0028] Wherein, any of the plurality of annular heat sinks is provided with a through hole. The through hole of the annular heat sink arranged adjacent to the water inlet is connected to the water inlet, and any two adjacent heat exchange channels are connected through the through hole.

[0029] Specifically, the through holes of any two adjacent annular heat sinks are arranged in a staggered manner. The two adjacent annular heat sinks are respectively recorded as the first annular heat sink and the second annular heat sink. Along the direction from the first annular heat sink to the second annular heat sink, the orthographic projection of the through hole of the first annular heat sink on the second annular heat sink is located on one side of the through hole of the second annular heat sink. This arrangement enables the water flow to flow effectively in each heat exchange channel to fully absorb heat. If the through holes of two adjacent annular heat sinks are arranged relative to each other, the water flow will flow directly from the through holes to the annular heat sink at the bottom layer, which will cause the water flow to be unable to fully absorb heat and cannot be completely vaporized. In this way, the purpose of rapid and large-scale steam output cannot be achieved.

[0030] In some embodiments, optionally, a converging chamber is further provided in the humidifying body, and the converging chamber is located on one side of the heat exchange channel, and the heat exchange channel is connected to the water inlet and the exhaust port through the converging chamber.

[0031] In this embodiment, the structure of the humidifying body is further limited, so that a converging cavity is further provided in the humidifying body, and the converging cavity is located on one side of at least one heat exchange channel. When there are multiple heat exchange channels, the heat exchange channel arranged adjacent to the converging cavity among the multiple heat exchange channels is connected to the converging cavity, the converging cavity is connected to the water inlet, and the converging cavity is connected to the exhaust port.

[0032] When the humidifier is working, water flows into the converging chamber through the water inlet, and then falls into the heat exchange channel adjacent to the converging chamber under the action of gravity, and flows downward through the multiple heat exchange channels in sequence along the direction in which the multiple heat exchange channels are stacked.

[0033] The vaporized water vapor will move upward (i.e., in the opposite direction of gravity) and gather in the gathering cavity, and then spray into the cooking cavity of the cooking appliance through the exhaust port to achieve the purpose of moisturizing the food in the cooking cavity. The gathering cavity has the function of gathering and rectifying the steam, so that the steam can flow quickly to the exhaust port.

[0034] In some embodiments, optionally, when there are multiple heat exchange channels, along the direction from the converging cavity to the heat exchange channel, the sum of the heights of the multiple heat exchange channels is greater than the height of the converging cavity.

[0035] In this embodiment, the matching structure of the converging cavity and the plurality of heat exchange channels is further defined.

[0036] Along the direction from the converging cavity to the heat exchange channel, the sum of the heights of the plurality of heat exchange channels is greater than the height of the converging cavity.

[0037] It can also be said that the volume of the converging chamber is smaller than the sum of the volumes of the plurality of heat exchange channels. In this way, the heat exchange area of ​​the humidifier and the use requirements of the collected water vapor are taken into account, and the working efficiency of the humidifier can be guaranteed.

[0038] In some embodiments, optionally, the humidifier body also includes: a second heating part, the second heating part is connected to one side of the first heating part, and the second heating part is connected to the convergence chamber; the humidifier also includes a wiring terminal, the wiring terminal is arranged on the shell, and the second heating part and the first heating part are both electrically connected to the wiring terminal.

[0039] In this embodiment, the humidifying body further includes a second heating portion, the second heating portion is connected to the first heating portion, and the second heating portion is located on one side of the first heating portion.

[0040] The second heating part is connected to the converging cavity, that is, at least a part of the second heating part is located in the converging cavity. The second heating part can heat the converging cavity when it is working, and the water flow entering the converging cavity through the water inlet can absorb the heat generated by the second heating part when it is working. The first heating part and the second heating part cooperate to accelerate the vaporization speed of water, which is beneficial to improve the steam output efficiency of the humidifier.

[0041] At the same time, at least a part of the second heating part is located in the converging chamber. Therefore, the water vapor gathered in the converging chamber can further absorb the heat generated by the operation of the second heating part. In this way, the newly formed water vapor can be further prevented from condensing, which is beneficial to improving the steam output efficiency of the humidifier and reducing the energy consumption of the product.

[0042] In addition, the humidifier also includes a terminal disposed on the housing, and the second heating part and the first heating part are both electrically connected to the terminal. External devices can be electrically connected to the second heating part and the first heating part through the terminal to achieve the purpose of controlling the operation of the second heating part and the first heating part.

[0043] In some embodiments, optionally, the shell includes: a shell body, the first heating part and the heat dissipation element are both arranged in the shell body; a connecting plate, arranged at one end of the shell body, the connecting plate is provided with a water inlet and an exhaust port; a steam hood, arranged on the side of the connecting plate away from the shell body, the steam hood is provided with a steam nozzle, and the steam nozzle is connected to the exhaust port; wherein the exhaust port is a honeycomb port.

[0044] In this embodiment, the structure of the shell is further defined such that the shell includes a shell body, a connecting plate and a steam cover.

[0045] The first heating part and the heat dissipating element are both arranged in the shell body, and the connecting plate is arranged at one end of the shell body.

[0046] The connecting plate is provided with a water inlet and an exhaust port, the steam hood is arranged on a side of the connecting plate away from the shell body, the steam hood is provided with a steam nozzle, and the steam nozzle is communicated with the exhaust port.

[0047] That is, water flows through the water inlet of the connecting plate to the converging chamber, and water vapor is discharged from the steam nozzle through the exhaust port and the steam hood.

[0048] Among them, the exhaust port is a honeycomb port, that is, a small steam gathering area is formed at the exhaust port. The honeycomb port has the function of breaking up the airflow so that the steam can flow evenly and orderly. In this way, it is convenient for the steam to be sprayed into the cooking cavity through the steam nozzle smoothly, which is beneficial to increase the speed of steam output.

[0049] In some embodiments, optionally, the humidifying body further includes: a first sealing portion, the first sealing portion is located between the first heating portion and the heat sink, and the first sealing portion is used to seal the connection between the first heating portion and the heat sink.

[0050] In this embodiment, the structure of the humidifying body is further defined.

[0051] The humidifying body further includes a first sealing portion, which is located between the first heating portion and the heat sink, and is used to seal the connection between the first heating portion and the heat sink. In this way, water will not flow down through the connection between the first heating portion and the heat sink. In other words, it is possible to prevent water from flowing down along the first heating portion directly, and avoid the situation where water cannot be completely vaporized due to insufficient absorption of heat, thereby ensuring the speed and amount of steam output.

[0052] In some embodiments, optionally, the humidifying body further includes: a second sealing portion, the second sealing portion is located between the heat sink and the inner surface of the shell, and the second sealing portion is used to seal the connection between the heat sink and the inner surface of the shell.

In this way, water will not flow down through the connection between the heat sink and the inner surface of the housing. In other words, it is possible to prevent water from flowing down directly along the inner surface of the housing, and avoid the situation where water cannot be completely vaporized due to insufficient absorption of heat, thereby ensuring the speed and amount of steam output.

[0055] In some embodiments, optionally, the humidifier further includes: a water inlet pipe, at least a portion of which is located on one side of the shell, and the water inlet pipe is connected to the water inlet; and a mounting bracket, which is disposed on one side of the shell.

[0056] In this embodiment, the structure of the humidifier is further defined so that the humidifier further includes a water inlet pipe and a mounting bracket.

[0057] The water inlet pipe is connected with the water inlet, and water flows through the water inlet pipe to the water inlet.

[0058] The mounting bracket is arranged on one side of the shell, and is used for mounting and positioning the shell, that is, the mounting bracket is used for assembling with other components of the cooking appliance.

DETAILED DESCRIPTION

[0085] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0086] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0087] Refer to the following Figures 1 to 10 A humidifier 10 and a cooking appliance 90 according to some embodiments of the present application.

[0088] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a humidifier 10 according to some embodiments of the present application is used for a cooking utensil 90 , and the humidifier 10 includes a humidifying body 100 and a first heating part 200 .

[0089] The humidifying body 100 is provided with a water inlet 110 and an air outlet 120 .

[0090] At least one heat exchange channel 140 is disposed in the humidification body 100 .

[0091] When there are plural heat exchange channels 140 , the plurality of heat exchange channels 140 are stacked.

[0092] Any two adjacent heat exchange channels 140 are connected.

[0093] The first heating part 200 is disposed on the humidifying body 100 .

[0094] Each heat exchange channel 140 is connected to the first heat generating part 200 .

[0095] Among the plurality of heat exchange channels 140 , one heat exchange channel 140 located at the end is communicated with any one of the water inlet 110 and the exhaust port 120 .

[0096] A humidifier 10 provided in the present application includes a humidifying body 100 and a first heating part 200 .

[0097] The humidifying body 100 is provided with a water inlet 110 and an exhaust port 120, and at least one heat exchange channel 140 is provided in the humidifying body 100. When the number of the heat exchange channels 140 is multiple, the multiple heat exchange channels 140 are stacked. Among the multiple heat exchange channels 140, one heat exchange channel 140 located at the end is communicated with the water inlet 110, and the heat exchange channel 140 is also communicated with the exhaust port 120. Any two adjacent heat exchange channels 140 among the multiple heat exchange channels 140 are communicated.

[0098] When the humidifier 10 is working, water enters the humidifier 10 through the water inlet 110, and then falls into the heat exchange channel 140 arranged adjacent to the water inlet 110 under the action of gravity, and flows downward through the multiple heat exchange channels 140 in sequence along the direction in which the multiple heat exchange channels 140 are stacked. Since any heat exchange channel 140 among the multiple heat exchange channels 140 is connected to the first heating part 200, the heat generated by the operation of the first heating part 200 can be transferred to the multiple heat exchange channels 140, and the water flow will fully absorb the heat at the heat exchange channel 140 and be completely vaporized when flowing along the heat exchange channel 140. That is, when the water flow flows through the heat exchange channel 140, a vapor-liquid phase change will occur to form water vapor. The vaporized water vapor will move upward (i.e., in the direction opposite to the gravity direction), and then spray into the cooking cavity 910 of the cooking device 90 through the exhaust port 120, so as to moisten the food in the cooking cavity 910, and can adjust the moisture content in the cooking cavity 910, and prevent the food from drying out when the cooking device 90 is cooking (e.g., the cooking device 90 is in the microwave mode, the single microwave mode, or the single baking mode), which is beneficial to improving the cooking effect of the cooking device 90. Moreover, this setting can also be used in combination with the self-cleaning mode of the cooking device 90, for example, when the cooking cavity 910 is self-cleaning, the steam sprayed by the humidifier 10 can dry and sterilize the cooking cavity 910 at high temperature.

[0099] It can be understood that each heat exchange channel 140 is connected to the first heating part 200, and any two adjacent heat exchange channels 140 among the multiple heat exchange channels 140 are connected, so the water flow will flow through the multiple heat exchange channels 140 in sequence under the action of gravity, that is, the water flow will sequentially exchange heat with the multiple heat exchange channels 140. This arrangement enables the humidifier 10 to have a larger effective heat exchange area, greatly increases the heating surface area of ​​the first heating part 200, maximizes the heating effect under unit power, and can quickly heat water.

[0100] It is understandable that the vaporized water vapor will flow upward through the multiple heat exchange channels 140 in sequence, and then flow to the exhaust port 120. When the water vapor flows through the multiple heat exchange channels 140, the heat at the heat exchange channels 140 can effectively prevent the newly formed water vapor from condensing, and can achieve rapid and maximum steam output, which is beneficial to improving the working efficiency of the humidifier 10 and reducing the energy consumption of the humidifier 10.

[0101] In some embodiments, optionally, Figure 5 As shown, the humidifying body 100 includes a housing 150 and a heat sink 160 .

[0102] The housing 150 is provided with a water inlet 110 and an exhaust port 120 .

[0103] The first heating portion 200 is disposed in the housing 150 .

[0104] The heat sink 160 is connected between the first heat generating portion 200 and the inner surface of the housing 150 .

[0105] The heat sink 160 and the inner surface of the housing 150 enclose at least one heat exchange channel 140 .

[0106] In this embodiment, the structure of the humidifying body 100 is further defined such that the humidifying body 100 includes a housing 150 and a heat sink 160 .

[0107] The first heating portion 200 and the heat sink 160 are both located in the housing 150 .

[0108] The housing 150 is provided with a water inlet 110 and an exhaust port 120 .

[0109] The heat sink 160 is connected to the outer surface of the first heating portion 200 and the inner surface of the housing 150 . The heat sink 160 and the inner surface of the housing 150 enclose a plurality of heat exchange channels 140 .

[0110] Since the heat sink 160 is connected to the first heating part 200, the heat sink 160 has the function of increasing the heating area of ​​the first heating part 200, so that water at different positions of the heat exchange channel 140 can effectively contact the heat, which is beneficial to improving the heat exchange efficiency, facilitating rapid and maximum steam release, and effectively preventing the condensation of newly formed water vapor.

[0111] It can be understood that a first portion of the outer edge of the heat sink 160 is connected to the first heating portion 200 , and a second portion of the outer edge of the heat sink 160 is connected to the inner surface of the housing 150 .

[0112] In some embodiments, optionally, Figure 3 As shown, when the number of the heat exchange channels 140 is plural, the heat sink 160 includes spiral fins 160a.

[0113] The spiral fin 160a has a first outer edge and a second outer edge that are oppositely disposed.

[0114] The first outer edge is connected to the first heat generating portion 200 .

[0115] The second outer edge is connected to the inner surface of the housing 150 .

[0116] The spiral fins 160 a extend along the stacking direction of the plurality of heat exchange channels 140 .

[0117] In this embodiment, the structure of the heat sink 160 is further defined so that the heat sink 160 includes a spiral fin 160a, the spiral fin 160a has a first outer edge and a second outer edge, the first outer edge and the second outer edge are arranged opposite to each other, the first outer edge is connected to the first heating part 200, and the second outer edge is connected to the inner surface of the shell 150.

[0118] The spiral fin 160a extends along the stacking direction of the plurality of heat exchange channels 140. The extension direction of the spiral fin 160a determines the extension shape of the plurality of heat exchange channels 140. That is, the plurality of heat exchange channels 140 are sequentially connected to form a spiral channel structure, and water will flow along the spiral channel structure, and the water flow will fully absorb the heat generated by the operation of the first heating part 200, which can ensure the efficiency of vaporization and provide structural support for rapid and large-scale steam output.

[0119] In some embodiments, optionally, Fig. 9 As shown, when the number of the heat exchange channels 140 is plural, the heat sink 160 includes a plurality of annular heat sinks 160 b.

[0120] The plurality of annular fins 160 b are arranged at intervals along the stacking direction of the plurality of heat exchange channels 140 .

[0121] The inner peripheral wall of the annular heat sink 160 b is connected to the first heat generating portion 200 .

[0122] The outer peripheral wall of the annular heat sink 160 b is connected to the inner surface of the housing 150 .

[0123] Each annular heat sink 160b is provided with a through hole 162, and the through holes 162 of any two adjacent annular heat sinks 160b are staggered.

[0124] In this embodiment, the structure of the heat sink 160 is further defined such that the heat sink 160 includes a plurality of annular heat sinks 160 b .

[0125] Any of the plurality of annular heat sinks 160 b has an inner circumferential wall and an outer circumferential wall. The inner circumferential wall of the annular heat sink 160 b is connected to the outer surface of the first heating part 200 , and the outer circumferential wall of the annular heat sink 160 b is connected to the inner surface of the housing 150 .

[0126] Along the stacking direction of the plurality of heat exchange channels 140 , a plurality of annular fins 160 b are arranged at intervals.

[0127] The plurality of annular heat sinks 160 b and the inner surface of the shell 150 enclose a plurality of heat exchange channels 140 .

[0128] Any of the plurality of annular heat sinks 160b is provided with a through hole 162. The through hole 162 of the annular heat sink 160b disposed adjacent to the water inlet 110 is connected to the water inlet 110, and any two adjacent heat exchange channels 140 are connected through the through hole 162.

[0129] Specifically, the through holes 162 of any two adjacent annular heat sinks 160b are arranged in a staggered manner. The two adjacent annular heat sinks 160b are respectively recorded as the first annular heat sink 160b and the second annular heat sink 160b. Along the direction from the first annular heat sink 160b to the second annular heat sink 160b, the orthographic projection of the through hole 162 of the first annular heat sink 160b on the second annular heat sink 160b is located on one side of the through hole 162 of the second annular heat sink 160b. This arrangement enables the water flow to flow effectively in each heat exchange channel 140 to fully absorb heat. If the through holes 162 of two adjacent annular heat sinks 160b are arranged relative to each other, then the water flow will flow directly from the through hole 162 to the bottommost annular heat sink 160b, which will cause the water flow to be unable to fully absorb heat and cannot be completely vaporized, so that the purpose of rapid and large-scale steam output cannot be achieved.

[0130] In some other embodiments, the heat sink 160 includes a plurality of arc-shaped heat sinks, the inner peripheral wall of each arc-shaped heat sink is connected to the first heating part 200, the outer peripheral wall of each arc-shaped heat sink is connected to the inner surface of the shell 150, and the plurality of arc-shaped heat sinks are arranged at intervals along the stacking direction of the plurality of heat exchange channels 140, and any two adjacent arc-shaped heat sinks are arranged in a staggered manner. In this way, it is possible to prevent the water flow from directly flowing from the gap formed by the arc-shaped heat sink and the inner surface of the shell 150 to the bottom layer of the heat exchange channel 140, which can ensure that the water flow fully absorbs heat and ensures rapid and large-scale steam output. The two adjacent arc-shaped heat sinks are respectively recorded as the first arc-shaped heat sink and the second arc-shaped heat sink. Along the stacking direction of the plurality of heat exchange channels 140, the first arc-shaped heat sink is projected on the plane where the second arc-shaped heat sink is located, and the projection of the first arc-shaped heat sink is located on one side of the second arc-shaped heat sink, or a part of the projection of the first arc-shaped heat sink overlaps with the second arc-shaped heat sink.

[0131] In some embodiments, optionally, Figure 5 , Figure 6 and Figure 7 As shown, a convergence chamber 130 is further provided in the humidifying body 100 .

[0132] The converging chamber 130 is located at one side of the heat exchange channel 140 .

[0133] The heat exchange channel 140 is connected to the water inlet 110 and the exhaust port 120 through the converging cavity 130 .

[0134] In this embodiment, the structure of the humidification body 100 is further defined, so that a convergence chamber 130 is further provided in the humidification body 100, and the convergence chamber 130 is located on one side of at least one heat exchange channel 140. When the number of the heat exchange channels 140 is multiple, among the multiple heat exchange channels 140, the heat exchange channel 140 disposed adjacent to the convergence chamber 130 is communicated with the convergence chamber 130, the convergence chamber 130 is communicated with the water inlet 110, and the convergence chamber 130 is communicated with the exhaust port 120.

[0135] When the humidifier 10 is working, water flows into the converging chamber 130 through the water inlet 110, and then falls into the heat exchange channel 140 adjacent to the converging chamber 130 under the action of gravity, and flows downward through the multiple heat exchange channels 140 in sequence along the overlapping direction of the multiple heat exchange channels 140.

[0136] The vaporized water vapor moves upward (i.e., in the direction opposite to the gravity direction) and gathers in the gathering chamber 130, and then sprays into the cooking chamber 910 of the cooking device 90 through the exhaust port 120, so as to moisturize the food in the cooking chamber 910. The gathering chamber 130 has the function of gathering and rectifying the steam, so that the steam can flow quickly to the exhaust port 120.

[0137] In some embodiments, optionally, when there are multiple heat exchange channels 140 , along the direction from the converging cavity 130 to the heat exchange channels 140 , the sum of the heights of the multiple heat exchange channels 140 is greater than the height of the converging cavity 130 .

[0138] In this embodiment, the matching structure of the converging cavity 130 and the plurality of heat exchange channels 140 is further defined.

[0139] Along the direction from the converging cavity 130 to the heat exchange channel 140 , the sum of the heights of the plurality of heat exchange channels 140 is greater than the height of the converging cavity 130 .

[0140] It can also be said that the volume of the converging chamber 130 is smaller than the sum of the volumes of the plurality of heat exchange channels 140. In this way, the heat exchange area of ​​the humidifier 10 and the use requirements of the concentrated water vapor are taken into account, and the working efficiency of the humidifier 10 can be guaranteed.

[0141] Optionally, the ratio of the sum of the heights of the plurality of heat exchange channels 140 to the height of the converging chamber 130 is greater than or equal to 1.5 and less than or equal to 3. For example, the ratio of the sum of the heights of the plurality of heat exchange channels 140 to the height of the converging chamber 130 includes 1.6, 1.8, 2, 2.2, 2.4, 2.6, 2.8, etc., which are not listed here one by one.

[0142] In some embodiments, optionally, Figure 5 , Figure 6 and Figure 7 As shown, the humidifying body 100 further includes a second heating portion 300 .

[0143] The second heating portion 300 is connected to one side of the first heating portion 200 , and the second heating portion 300 is connected to the converging cavity 130 .

[0144] The humidifier 10 further includes a terminal 400 .

[0145] The connection terminal 400 is disposed on the housing 150 .

[0146] The second heat generating portion 300 and the first heat generating portion 200 are both electrically connected to the connection terminal 400 .

[0147] In this embodiment, the humidification body 100 further includes a second heating portion 300 , which is connected to the first heating portion 200 , and is located at one side of the first heating portion 200 .

[0148] The second heating part 300 is connected to the converging cavity 130, that is, at least a part of the second heating part 300 is located in the converging cavity 130. The second heating part 300 can heat the converging cavity 130 when it is working, and the water flow entering the converging cavity 130 through the water inlet 110 can absorb the heat generated by the second heating part 300 when it is working. The first heating part 200 and the second heating part 300 cooperate to accelerate the vaporization speed of water, which is beneficial to improve the steam output efficiency of the humidifier 10.

[0149] At the same time, at least a part of the second heating part 300 is located in the gathering chamber 130. Therefore, the water vapor gathered in the gathering chamber 130 can further absorb the heat generated by the operation of the second heating part 300. In this way, the newly formed water vapor can be further prevented from condensing, which is beneficial to improving the steam output efficiency of the humidifier 10 and reducing the energy consumption of the product.

[0150] In addition, the humidifier 10 further includes a terminal 400 disposed on the housing 150, and the second heating part 300 and the first heating part 200 are both electrically connected to the terminal 400. An external device can be electrically connected to the second heating part 300 and the first heating part 200 through the terminal 400 to achieve the purpose of controlling the operation of the second heating part 300 and the first heating part 200.

[0151] Optionally, the first heating part 200 and the second heating part 300 are formed integrally. This structural arrangement simplifies the molding process of the first heating part 200 and the second heating part 300 because the assembly process of the first heating part 200 and the second heating part 300 is omitted, which is conducive to improving the processing efficiency and assembly efficiency of the product.

[0152] Optionally, the first heating part 200 and the second heating part 300 are detachably connected. The connection method of the first heating part 200 and the second heating part 300 includes any one of the following or a combination thereof: screw connection, riveting and plug connection. This arrangement ensures the reliability of the connection between the first heating part 200 and the second heating part 300 while facilitating the cleaning and maintenance of the first heating part 200 and the second heating part 300, and reduces the possibility of bacterial growth. That is, the first heating part 200 and the second heating part 300 can be separated according to actual use needs, or the first heating part 200 and the second heating part 300 can be assembled together. This arrangement has a simple assembly and disassembly process, and is conducive to the cleaning of the first heating part 200 and the second heating part 300 and the subsequent repair and maintenance.

[0153] In the present application, the first heating part 200 is electrically connected to the connection terminal 400 through the second heating part 300 .

[0154] In some other embodiments, the first heating portion 200 is directly electrically connected to the terminal 400 , and the second heating portion 300 is directly electrically connected to the terminal 400 .

[0155] In some other embodiments, the second heating portion 300 is electrically connected to the connection terminal 400 through the first heating portion 200 .

[0156] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the housing 150 includes a housing body 152 , a connecting plate 154 and a steam cover 156 .

[0157] The first heating portion 200 and the heat sink 160 are both disposed in the shell body 152 .

[0158] The connecting plate 154 is disposed at one end of the shell body 152 .

[0159] The connecting plate 154 is provided with a water inlet 110 and an exhaust port 120 .

[0160] The steam cover 156 is disposed on a side of the connecting plate 154 facing away from the shell body 152 .

[0161] The steam hood 156 is provided with a steam nozzle 1562 .

[0162] The steam nozzle 1562 is connected to the exhaust port 120 .

[0163] The exhaust port 120 is a honeycomb port.

[0164] In this embodiment, the structure of the housing 150 is further defined such that the housing 150 includes a housing body 152 , a connecting plate 154 and a steam cover 156 .

[0165] The first heating portion 200 and the heat sink 160 are both disposed in the shell body 152 , and the connecting plate 154 is disposed at one end of the shell body 152 .

[0166] The connecting plate 154 is provided with a water inlet 110 and an exhaust port 120 . The steam hood 156 is provided on a side of the connecting plate 154 away from the shell body 152 . The steam hood 156 is provided with a steam nozzle 1562 . The steam nozzle 1562 is communicated with the exhaust port 120 .

[0167] That is, water flows through the water inlet 110 of the connecting plate 154 to the converging chamber 130. The water vapor passes through the exhaust port 120 and the steam cover 156 and is discharged from the steam nozzle 1562.

[0168] Among them, the exhaust port 120 is a honeycomb port, that is, a small steam gathering area is formed at the exhaust port 120. The honeycomb port has the function of breaking up the airflow so that the steam can flow evenly and orderly. In this way, it is convenient for the steam to be smoothly sprayed into the cooking cavity 910 through the steam nozzle 1562, which is beneficial to increase the speed of steam output.

[0169] Optionally, the terminal 400 is connected to the steam hood 156 .

[0170] In some embodiments, optionally, Figure 6 As shown, the humidifying body 100 further includes a first sealing portion 500 .

[0171] The first sealing portion 500 is located between the first heat generating portion 200 and the heat dissipating member 160 .

[0174] The humidifying body 100 further includes a first sealing portion 500, which is located between the first heating portion 200 and the heat sink 160, and is used to seal the connection between the first heating portion 200 and the heat sink 160. In this way, water will not flow down through the connection between the first heating portion 200 and the heat sink 160. In other words, it is possible to prevent water from flowing down along the first heating portion 200 directly, and avoid the situation where water cannot be completely vaporized due to insufficient absorption of heat, thereby ensuring the speed and amount of steam output.

[0175] Optionally, the first sealing portion 500 includes solder and an adhesive portion.

[0176] In some embodiments, optionally, Figure 6 As shown, the humidifying body 100 further includes a second sealing portion 600 .

[0177] The second sealing portion 600 is located between the heat sink 160 and the inner surface of the housing 150 .

[0178] The second sealing portion 600 is used to seal the connection between the heat sink 160 and the inner surface of the housing 150 .

[0179] In this embodiment, the structure of the humidifying body 100 is further defined.

[0180] The humidifying body 100 further includes a second sealing portion 600, which is located between the heat sink 160 and the inner surface of the housing 150, and is used to seal the connection between the heat sink 160 and the inner surface of the housing 150. In this way, water will not flow down through the connection between the heat sink 160 and the inner surface of the housing 150. In other words, it is possible to prevent water from flowing down directly along the inner surface of the housing 150, and avoid the situation where water cannot be completely vaporized due to insufficient absorption of heat, thereby ensuring the speed and amount of steam output.

[0181] Optionally, the second sealing portion 600 includes an adhesive portion and a card slot, etc., which are not listed here one by one.

[0182] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the humidifier 10 further includes a water inlet pipe 700 and a mounting bracket 800 .

[0183] At least a portion of the water inlet pipe 700 is located on one side of the housing 150 .

[0184] The water inlet pipe 700 is connected to the water inlet 110 .

[0185] The mounting bracket 800 is disposed on one side of the housing 150 .

[0186] In this embodiment, the structure of the humidifier 10 is further defined such that the humidifier 10 further includes a water inlet pipe 700 and a mounting bracket 800 .

[0187] The water inlet pipe 700 is connected to the water inlet 110 , and water flows through the water inlet pipe 700 toward the water inlet 110 .

[0188] The mounting bracket 800 is disposed on one side of the housing 150 , and the mounting bracket 800 is used for mounting and positioning the housing 150 , that is, the mounting bracket 800 is used for assembling with other components of the cooking appliance 90 .

[0189] Optionally, the water inlet pipe 700 is used to communicate with a water supply part of a steam generator (the steam generator is a component of the cooking appliance 90).

[0190] In some embodiments, optionally, the housing 150 is a glass tube, and the first heating part 200 and the second heating part 300 are both heating tubes.

[0191] In this embodiment, the types of the housing 150 , the first heat generating portion 200 , and the second heat generating portion 300 are specifically defined.

[0192] Specifically, the housing 150 is a glass tube.

[0193] Specifically, the first heating part 200 is a heating tube.

[0194] Specifically, the second heating part 300 is a heating tube.

[0195] like Fig.10 As shown, a cooking appliance 90 according to some embodiments of the present application includes: a humidifier 10 as in any of the above embodiments.

[0196] The cooking appliance 90 provided in the present application includes a humidifier 10 .

[0197] The humidifier 10 includes a humidification body 100 and a first heating part 200 .

[0198] The humidifying body 100 is provided with a water inlet 110 and an exhaust port 120, and at least one heat exchange channel 140 is provided in the humidifying body 100. When the number of the heat exchange channels 140 is multiple, the multiple heat exchange channels 140 are stacked. Among the multiple heat exchange channels 140, the heat exchange channel 140 located at the end is communicated with the water inlet 110, and the heat exchange channel 140 located at the end is communicated with the exhaust port 120. Any two adjacent heat exchange channels 140 among the multiple heat exchange channels 140 are communicated.

[0199] When the humidifier 10 is working, water enters the humidifier 10 through the water inlet 110, and then falls into the heat exchange channel 140 arranged adjacent to the water inlet 110 under the action of gravity, and flows downward through the multiple heat exchange channels 140 in sequence along the direction in which the multiple heat exchange channels 140 are stacked. Since any heat exchange channel 140 among the multiple heat exchange channels 140 is connected to the first heating part 200, the heat generated by the operation of the first heating part 200 can be transferred to the multiple heat exchange channels 140, and the water flow will fully absorb the heat at the heat exchange channel 140 and be completely vaporized when flowing along the heat exchange channel 140. That is, when the water flow flows through the heat exchange channel 140, a vapor-liquid phase change will occur to form water vapor. The vaporized water vapor will move upward (i.e., in the direction opposite to the gravity direction), and then spray into the cooking cavity 910 of the cooking device 90 through the exhaust port 120, so as to moisten the food in the cooking cavity 910, and can adjust the moisture content in the cooking cavity 910, and prevent the food from drying out when the cooking device 90 is cooking (e.g., the cooking device 90 is in the microwave mode, the single microwave mode, or the single baking mode), which is beneficial to improving the cooking effect of the cooking device 90. Moreover, this setting can also be used in combination with the self-cleaning mode of the cooking device 90, for example, when the cooking cavity 910 is self-cleaning, the steam sprayed by the humidifier 10 can dry and sterilize the cooking cavity 910 at high temperature.

[0200] It can be understood that each heat exchange channel 140 is connected to the first heating part 200, and any two adjacent heat exchange channels 140 among the multiple heat exchange channels 140 are connected, so the water flow will flow through the multiple heat exchange channels 140 in sequence under the action of gravity, that is, the water flow will sequentially exchange heat with the multiple heat exchange channels 140. This arrangement enables the humidifier 10 to have a larger effective heat exchange area, greatly increases the heating surface area of ​​the first heating part 200, maximizes the heating effect under unit power, and can quickly heat water.

[0201] It is understandable that the vaporized water vapor will flow upward through the multiple heat exchange channels 140 in sequence, and then flow to the exhaust port 120. When the water vapor flows through the multiple heat exchange channels 140, the heat at the heat exchange channels 140 can effectively prevent the newly formed water vapor from condensing, and can achieve rapid and maximum steam output, which is beneficial to improving the working efficiency of the humidifier 10 and reducing the energy consumption of the humidifier 10.

[0202] In some embodiments, optionally, Fig.10 As shown, the cooking appliance 90 further includes a housing and an appliance body 900 .

[0203] The device body 900 is disposed in the housing.

[0204] A cooking cavity 910 is disposed in the appliance body 900 .

[0205] The humidifier 10 is located between the housing and the appliance body 900 .

[0206] The steam nozzle 1562 of the humidifier 10 is connected to the cooking cavity 910 .

[0207] A cooking cavity 910 is provided in the appliance body 900 , and food materials are placed in the cooking cavity 910 .

[0208] The humidifier 10 is located between the housing and the appliance body 900 , and the steam nozzle 1562 of the humidifier 10 is in communication with the cooking cavity 910 .

[0209] Optionally, the cooking appliance 90 includes a steam generator, and the humidifier 10 uses the water supply part of the steam generator to replenish water, avoiding the addition of additional water supply devices, which is conducive to reducing the production cost of the cooking appliance 90.

[0210] Optionally, the cooking appliance 90 includes a microwave oven, a microwave steam oven, etc., which are not listed here one by one.

[0211] Optionally, the size of the humidifier 10 is Φ20 mm×150 mm. The small size of the humidifier 10 reduces the occupancy rate of the internal space of the cooking utensil 90 and facilitates the reasonable layout of other components of the cooking utensil 90.

[0212] The humidifier 10 is installed on the side of the appliance body 900 of the cooking appliance 90. The water inlet pipe 700 of the humidifier 10 is connected to the water supply part of the steam generator of the cooking appliance 90. No water supply mechanism such as a water pump is required, and the cost is controllable. The humidifier 10 can quickly and massively replenish moisture, adjust the moisture content inside the cooking cavity 910, and prevent the food from drying out when being cooked by micro-roasting.

[0213] The humidifier 10 of the present application is installed between the housing of the cooking appliance 90 and the appliance body 900 .

[0214] Optionally, the humidifier 10 is provided with a first heating part 200, a spiral fin 160a, a housing 150, a mounting bracket 800, a terminal 400 and a water inlet pipe 700. The first heating part 200 is wound with a spiral fin 160a (eg, the spiral fin 160a is a metal fin), and the housing 150 is a quartz glass tube.

[0215] Along the stacking direction of the plurality of heat exchange channels 140, the ratio of the length of the second heating portion 300 to the length of the first heating portion 200 is 2. The intermittent quantitative water flow controlled by the solenoid valve directly falls into the spiral fin 160a below, and the water flows downward along the spiral fin 160a by its own gravity, fully absorbing the heat of the spiral fin 160a and being completely vaporized.

[0216] The vaporized water vapor moves upward, gathers in the convergence chamber 130 at the top, and enters the cooking chamber 910 through the two steam nozzles 1562 in front of the steam cover 156 , thereby completing the humidification of the cooking chamber 910 .

[0217] The spiral fin 160a is sealed to the inner surface of the shell 150 via the second sealing portion 600 to prevent water from flowing down from the inner surface of the shell 150, which would cause the water to not be fully vaporized due to insufficient heat absorption.

[0218] The first heating part 200 and the second heating part 300 are both heating tubes, the diameter of the heating tube is 10 mm, the number of spirals of the spiral fin 160 a is 20, and the pitch of the spiral fin 160 a is 4.5 mm.

[0219] The connecting plate 154 is provided with an exhaust port 120 and a water inlet 110 . The exhaust port 120 is a honeycomb port that breaks up the airflow to facilitate the steam to be smoothly sprayed into the cooking cavity 910 .

[0220] The spiral fins 160a greatly increase the heating surface area of ​​the heating pipe, thereby maximizing the heating effect under unit power, which is beneficial to improving the working efficiency of the humidifier 10 and preventing the condensation of newly formed water vapor.

[0221] The humidifier 10 is linked to the self-cleaning mode of the cooking appliance 90 . When the cooking cavity 910 is self-cleaned, the steam sprayed from the humidifier 10 can dry and sterilize the cooking cavity 910 at high temperature.

[0222] The humidifier 10 is located inside the cooking appliance 90 , and the controller of the cooking appliance 90 controls the operation of the humidifier 10 , that is, the automation level of the cooking appliance 90 is improved, eliminating the need for manual operation by the user.
