Description

Technical Field

[0001] The present disclosure relates to the technical field of cooking appliances, and particularly to a steaming and baking appliance. Background Art

[0002] With the development of cooking appliance technology, cooking appliances with steaming functions such as steamers are popular among health enthusiasts. Cooking appliances with steaming functions can utilize dynamic steam balance technology to retain the original nutritional components of food, which has promoted the emergence of steaming and baking integrated machines. Because the functions of a steamer and an oven are integrated into one, the steaming and baking integrated machine effectively reduces the occupation of kitchen space by independent steamers and ovens and is deeply loved by consumers.

[0003] In the cooking process of existing cooking appliances with steaming functions such as steaming and baking integrated machines, the amount of externally discharged steam is large, resulting in a relatively high temperature of the externally discharged steam. The temperature of the externally discharged steam has always attracted people's attention. A high temperature is not only likely to cause discomfort to the human body, but may even burn the human skin. Therefore, a relatively low externally discharged steam and its temperature are particularly important. In addition, the external discharge of steam will affect the working time of the cooking appliance, and a separate pipeline needs to be set up to continuously supply water to the steam generator. Summary of the Utility Model

[0004] Based on this, in view of the above problems, it is necessary to provide a steaming and baking appliance.

[0005] An embodiment of the present disclosure provides a steaming and baking appliance, which includes an inner container, a steam generator, a heat dissipation device, and a condensation device; the inner container has a cooking cavity and an exhaust duct communicating with the cooking cavity; the steam generator is disposed in the cooking cavity and at the bottom of the inner container; the heat dissipation device is disposed on the outer wall of the inner container, and the heat dissipation device has a cold air cavity; the condensation device includes a water supply component and a condenser, the condenser has a condensation cavity, the condenser is disposed on the wall of the cold air cavity, the condensation cavity communicates with the cold air cavity; the water supply component is communicated with the condensation cavity, the condensation cavity communicates with the cooking cavity through the exhaust duct, and the air port of the exhaust duct located in the cooking cavity is above the steam generator.

[0006] The steam cooking equipment provided by the embodiments of the present disclosure allows the water in the water supply assembly to enter the inner container through the condensation chamber and the exhaust duct to supply water to the steam generator. The water supply pipeline is less and the connection is simple. When the water flow is in the condensation chamber, it can also cool and condense the high-temperature steam, causing the water temperature entering the steam generator to rise, saving energy, reducing the heating time, and prolonging the working time of the steaming function. At the same time, the high-temperature steam in the condensation chamber is cooled by both the air-cooling device at the bottom of the condenser and the water flow. When the temperature difference is too large, part of the high-temperature steam condenses into water and then returns to the steam generator through the exhaust duct, taking away the heat of the condensation chamber and being reused, improving the steam condensation and reflux effect. The remaining high-temperature steam is exhausted through the cold air chamber after the temperature drops, thereby improving the user's comfort. While solving the problem of the water supply pipeline of the steam generator, the high-temperature steam is cooled and the working time of the cooking equipment is prolonged.

[0007] In some embodiments, a plurality of guiding grooves are formed in the top wall of the condenser. The openings of the guiding grooves face the condensation chamber. The inner surface of the guiding groove is an arc surface, and the outer surface of the guiding groove protrudes from the outer surface of the top wall of the condenser.

[0008] With such a setting, the arc surface of the guiding groove can increase the contact area between the high-temperature steam and the condenser, facilitating the increase of the condensation effect and reducing the temperature of the high-temperature steam.

[0009] In some embodiments, the condenser is provided with an air inlet, and the air inlet communicates with the exhaust duct. The bottom wall of the condenser is inclined downward towards the air inlet, and the air inlet is located at the lowest point of the bottom wall of the condenser.

[0010] With such a setting, the bottom wall of the condenser is inclined and the air inlet is located at the lowest point of the bottom wall, which is convenient for the high-temperature steam to enter the condensation chamber upward and helps the water formed after the high-temperature steam condenses to flow back into the inner container to form steam for secondary utilization.

[0011] In some embodiments, a water inlet is formed in the side wall of the condenser. The water inlet communicates with the water supply assembly. The water inlet is arranged near the highest point of the bottom wall of the condenser; the bottom of the air inlet is lower than the inner surface of the bottom wall of the condenser, and the bottom of the water inlet is higher than the inner surface of the bottom wall of the condenser.

[0012] With such a setting, it is convenient for the water provided by the water supply assembly to flow from a high place to a low place, reducing the temperature of the bottom wall of the condenser and taking away the heat in the condensation chamber. The bottom of the air inlet being lower than the inner surface of the bottom wall of the condenser helps the water to flow into the inner container.

[0013] In some embodiments, the condenser is provided with at least one exhaust hole, and the exhaust hole communicates with the cold air chamber; the exhaust hole is located at the highest point of the bottom wall of the condenser, and a flanging protrudes from the upper surface of the bottom wall of the condenser connected to the exhaust hole.

[0014] This arrangement prolongs the flow time of high-temperature steam in the condensation chamber, and the high exhaust holes facilitate the steam to enter the cold air chamber and then be discharged after being cooled. The flange setting can prevent water from bypassing the exhaust holes and prevent water from flowing into the cold air chamber.

[0015] In some of the embodiments, the heat dissipation device includes a heat dissipation fan and an air guide plate. The air guide plate and the outer wall of the inner tank are combined to form a cold air cavity. The heat dissipation fan is connected to the cold air cavity, and the bottom wall of the condenser is in contact with the air guide plate.

[0016] With this arrangement, the heat dissipation fan can continuously provide cold air to the cold air chamber. The cold air chamber can cool down the high-temperature steam in the lower cavity by air cooling, while also dissipating heat to the inside of the inner pot, thereby reducing the overall temperature of the steaming and baking equipment.

[0017] In some of the embodiments, the bottom wall of the condenser fits the outer wall of the cold air chamber; the air guide plate is provided with an opening, and the outer wall of the condenser is adapted to the opening.

[0018] Such arrangement enables the bottom wall of the condenser to directly contact the flowing cooling airflow through the opening, thereby accelerating the speed of heat transfer and exchange. The flowing cooling airflow takes away more heat from the bottom wall of the condenser, increasing the effect of steam condensation reflux.

[0019] In some of the embodiments, an air inlet and at least one air outlet are provided on the air guide plate, the air inlet and the air outlet are located on both sides of the condenser, the air inlet is opened upward, and the heat dissipation fan is installed at the air inlet.

[0020] With this arrangement, the air inlet at the top facilitates the entry of cooling airflow, improving the smoothness of the cooling airflow in the condensing chamber, thereby fully dissipating the heat from the bottom of the condenser, taking away the cooled steam and eventually discharging it from the air outlet of the air guide plate, increasing the heat dissipation effect of air cooling.

[0021] In some of the embodiments, the condensing device further comprises a plurality of heat sinks, which are protruding from the bottom wall of the condenser, are located in the cold air cavity, and extend along the air inlet toward the air outlet.

[0022] With this arrangement, the heat sink can not only guide the cooling airflow, but also increase the contact area between the cooling airflow and the condensing device, thereby reducing the temperature of the bottom wall of the condenser and further improving the cooling and condensing effect of the condenser on high-temperature steam.

[0023] In some of the embodiments, the water supply assembly is disposed on the outer wall of the inner tank, and the water supply assembly includes a water tank, a water inlet pipe and a control valve. The water inlet pipe connects the water tank with the condensation chamber; the control valve is installed on the water inlet pipe.

[0024] With such a setting, the water volume can be controlled in real time through the control valve, ensuring sufficient water consumption of the steam generator, continuous water flow in the condensation chamber and no water flowing out from the exhaust holes, thereby ensuring the condensation effect on the high-temperature steam in the condensation chamber.

[0038] Refer to Figure 1 , Figure 1The overall structure of the steaming and baking device 100 in the embodiments of the present disclosure is shown. The present disclosure relates to the technical field of cooking devices. The steaming and baking device 100 of the present disclosure can be a steaming box, an oven, or a steaming and baking integrated machine, etc., which is a cooking device that utilizes the dynamic steam balance technology to retain the original nutritional components of food.

[0039] Referring Figure 2 and Figure 3 to, embodiments of the present disclosure provide a steaming and baking device 100, which includes an inner container 1, a steam generator 4, a condensation device 2, and a heat dissipation device 3. The inner container 1 has a cooking cavity 11, and the steam generator 4 is disposed in the cooking cavity 11 and at the bottom of the inner container 1; the inner container 1 also has an exhaust duct 12 communicating with the cooking cavity 11; the air port of the exhaust duct 12 located in the cooking cavity 11 is above the steam generator 4. Exemplarily, there is a baking tray for placing food in the cooking cavity 11, and the baking tray is filled with food and placed above the steam generator 4. The steam generator 4 is used to continuously generate high-temperature steam to heat the food until it is cooked; the exhaust duct 12 discharges the high-temperature steam generated by cooking through the air port. The heat dissipation device 3 is disposed on the outer wall of the inner container 1; the heat dissipation device 3 has a cold air cavity 31. Exemplarily, the heat dissipation device 3 is disposed above the inner container 1, and there is a flowing cooling air flow in the cold air cavity 31. The condensation device 2 includes a water supply component 22 and a condenser 21. The condenser 21 has a condensation cavity 211. The condenser 21 is disposed on the wall of the cold air cavity 31, and the condensation cavity 211 communicates with the cold air cavity 31; the water supply component 22 is communicated with the condensation cavity 211, and the condensation cavity 211 communicates with the cooking cavity 11 through the exhaust duct 12. Exemplarily, the condenser 21 is disposed above the heat dissipation device 3. After the water of the water supply component 22 enters the condensation cavity 211, it enters the inner container 1 through the exhaust duct 12 to provide the required water volume for the steam generator 4. Exemplarily, the high-temperature steam enters the condensation cavity 211 through the exhaust duct 12, and after cooling in the condensation cavity 211, the steam is discharged through the cold air cavity 31.

[0040] For the steaming and baking device 100 provided by the embodiments of the present disclosure, the steam generator 4 is located at the bottom of the inner container 1. The inner container 1 is communicated with the condensation cavity 211 through the exhaust duct 12, and the condensation cavity 211 is communicated with the water supply component 22, so that the water of the water supply component 22 can enter the inner container 1 through the condensation cavity 211 and the exhaust duct 12. The air port of the exhaust duct 12 is above the steam generator 4, so that the water drips from above or gradually converges on the upper surface of the steam generator 4 after entering the inner container 1, and the water can also cool and condense the high-temperature steam in the condensation cavity 211 when passing through the condensation cavity 211, so that the water temperature entering the steam generator 4 rises, saving energy and reducing the heating time; there is no need to separately set up a pipeline to supply water to the steam generator 4, and the water supply pipeline is less and the connection is simple.

[0041] In addition, for the steam cooking device 100 provided by the embodiments of the present disclosure, the high-temperature steam coming out of the steam generator 4 enters the condensation chamber 211 through the exhaust pipe 12. Since the condenser 21 is provided on the wall of the cold air chamber 31, the cooling air flow in the cold air chamber 31 can take away the heat of the high-temperature steam in the condenser 21, and at the same time, the water flow in the condenser 21 can also reduce the temperature of the high-temperature steam, so that the high-temperature steam is cooled by both air cooling and water cooling, thus facilitating the discharge through the outside of the cold air chamber 31 to improve the user's comfort.

[0042] In addition, when the temperature in the condensation chamber 211 is too low and the temperature of the high-temperature steam is high, resulting in too large a temperature difference, the high-temperature steam condenses into water. After the steam condenses into water, it returns to the upper part of the steam generator 4 through the exhaust pipe 12, taking away part of the heat of the condenser 21 and enabling the steam to be reused, improving the steam condensation and reflux effect. The temperature of the condensed water is relatively high and can quickly turn into steam in the steam generator 4 to continue heating food, saving the energy of the steam cooking device 100 and increasing the working time of the steaming function.

[0043] Exemplarily, the steam generator 4 is located in the central area at the bottom of the inner container 1, and the steam generator 4 is located at the lowest position of the inner container 1, so that the water at the bottom of the inner container 1 can converge from all around to the upper surface of the steam generator 4. Since the temperature of the upper surface of the steam generator 4 is relatively high, the water can be quickly heated to form high-temperature steam and move upward to steam and cook food.

[0044] Exemplarily, the shape of the inner container 1 is square, and both the condensation device 2 and the heat dissipation device 3 are located on the upper surface of the inner container 1. From bottom to top, there are the inner container 1, the heat dissipation device 3, and the condensation device 2 in sequence.

[0045] Exemplarily, the shape of the heat dissipation device 3 is an irregular shape. The shape of the condenser 21 is also an irregular shape. The irregular shape can extend the residence time of the cooling air flow and the high-temperature steam, increasing the heat dissipation effect of air cooling and liquid cooling.

[0046] Exemplarily, the material of the condenser 21 is a metal material or an alloy material. Since the metal material has good thermal conductivity and the heat transfer is rapid, it can improve the heat dissipation effect of both water cooling and air cooling. Exemplarily, the material of the condenser 21 is aluminum alloy. In other embodiments, the material of the condenser 21 can also be stainless steel or other materials with good thermal conductivity.

[0047] Reference Figures 1 to 4, in some embodiments, a plurality of guiding grooves 212 are formed in the top wall of the condenser 21. The opening 331 of the guiding groove 212 faces the condensation chamber 211. The inner surface of the guiding groove 212 is an arc surface, and the outer surface of the guiding groove 212 protrudes from the outer surface of the top wall of the condenser 21. With such a setting, the arc surface of the guiding groove 212 can increase the contact area between the high-temperature steam and the condenser 21, facilitating an increase in the condensation effect and a reduction in the temperature of the high-temperature steam.

[0048] Exemplarily, three guiding grooves 212 are formed in the top wall of the condenser 21. The three guiding grooves 212 have different extending lengths, and the groove widths and groove heights of the three guiding grooves 212 are the same. In other embodiments, two, four or more guiding grooves 212 may also be formed. The extending direction of the guiding groove 212 is not limited. The shape of the guiding groove 212 may also be square or other irregular shapes.

[0049] In other embodiments, the opening 331 of the guiding groove 212 faces away from the condensation chamber 211, such that the inner surface of the guiding groove 212 is lower than the outer surface of the top wall of the condenser 21, and the outer surface of the guiding groove 212 protrudes from the inner surface of the top wall of the condenser 21. With such a setting, the contact area between the high-temperature steam and the condenser 21 is also increased, facilitating an increase in the condensation effect and a reduction in the temperature of the high-temperature steam.

[0050] Reference Figure 4 , in some embodiments, the condenser 21 is provided with an air inlet 213. The air inlet 213 communicates with the exhaust duct 12. The bottom wall of the condenser 21 is inclined downward toward the air inlet 213, and the air inlet 213 is located at the lowest point of the bottom wall of the condenser 21. With such a setting, the bottom wall of the condenser 21 is inclined and the air inlet 213 is located at the lowest point of the bottom wall, facilitating the upward entry of the high-temperature steam into the condensation chamber 211 and also contributing to the water formed after the condensation of the high-temperature steam flowing back into the inner container 1 to form steam for secondary utilization.

[0051] Reference Figure 4 , in some embodiments, a water inlet 214 is formed in the side wall of the condenser 21. The water inlet 214 communicates with the water supply assembly 22, and the water inlet 214 is arranged near the highest point of the bottom wall of the condenser 21; the bottom of the air inlet 213 is lower than the inner surface of the bottom wall of the condenser 21, and the bottom of the water inlet 214 is higher than the inner surface of the bottom wall of the condenser 21. With such a setting, it is convenient for the water provided by the water supply assembly 22 to flow from a high place to a low place, reducing the temperature of the bottom wall of the condenser 21 and taking away the heat in the condensation chamber 211. The bottom of the air inlet 213 being lower than the inner surface of the bottom wall of the condenser 21 helps the water to flow into the inner container 1.

[0052] Exemplarily, the condenser 21 is inclined such that one end where the air inlet 213 is located is the lowest end of the condenser 21, and the other end where the water inlet 214 is located is higher than the end where the air inlet 213 is located. The water provided by the water supply assembly 22 flows into the condensation chamber 211 through the high-level water inlet 214, and the water flow flows along the inclined direction on the bottom wall of the condenser 21 to the lowest point and flows into the inner tank 1 through the air inlet 213 and the exhaust pipe 12. It can be understood that the inclination angle is determined according to actual needs. In other embodiments, the bottom wall of the condenser 21 can also be horizontally arranged.

[0053] Exemplarily, the connection between the air inlet 213 and the bottom wall of the condenser 21 is a bevel surface to facilitate the water flow.

[0054] Reference Figure 4 , in some embodiments, the condenser 21 is provided with at least one exhaust hole 215, and the exhaust hole 215 communicates with the cold air chamber 31; the exhaust hole 215 is located at the highest point of the bottom wall of the condenser 21, and the upper surface of the bottom wall of the condenser 21 connected to the exhaust hole 215 is convexly provided with a flange 216. With such a setting, the flow time of the high-temperature steam in the condensation chamber 211 is extended, and the high-level exhaust hole 215 facilitates the discharged steam after cooling to enter the cold air chamber 31. The setting of the flange 216 can prevent the water flow from flowing around the exhaust hole 215 and avoid the water from flowing into the cold air chamber 31 through the exhaust hole 215.

[0055] Exemplarily, three exhaust holes 215 are formed in the bottom wall of the condenser 21, and the three exhaust holes 215 are all located at the highest point of the bottom wall of the condenser 21. In other embodiments, the number of the exhaust holes 215 can also be two, four or more. Exemplarily, the sizes of the exhaust holes 215 are all different. In other embodiments, some of the sizes of the exhaust holes 215 can be the same or the sizes of the exhaust holes 215 are all the same.

[0056] Exemplarily, the height of the bottom wall of the condenser 21 corresponding to the water inlet 214 is lower than the bottom wall of the condenser 21 where the exhaust hole 215 is located, and the height of the water flow is not greater than the height of the flange 216 to prevent the water flow from being discharged through the exhaust hole 215 after entering.

[0057] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 , in some embodiments, the heat dissipation device 3 includes a heat dissipation fan 32 and a wind guide plate 33. The wind guide plate 33 and the outer wall of the inner tank 1 enclose a cold air chamber 31, the heat dissipation fan 32 communicates with the cold air chamber 31, and the bottom wall of the condenser 21 is attached to the wind guide plate 33. With such a setting, the heat dissipation fan 32 can continuously supply cold air to the cold air chamber 31. While the cold air chamber 31 cools the high-temperature steam in the lower cavity by air cooling, it can also dissipate heat from the inside of the inner tank 1 and reduce the overall temperature of the steaming and baking device 100.

[0058] Exemplarily, the air deflector 33 and the upper surface of the inner tank 1 enclose a cold air cavity 31. The side of the air deflector 33 where the heat dissipation fan 32 is located is the rear part. The condenser 21 is located in the middle of the air deflector 33 and the area of the middle part of the air deflector 33 covering the inner tank 1 is the smallest. The area of the front part of the air deflector 33 covering the inner tank 1 is larger than the area of the rear side of the air deflector 33 covering the inner tank 1. With such a setting, when the cooling air flow enters from the rear part and passes through the middle part, the flow rate is relatively fast and the temperature is relatively low, and the cooling effect on the high-temperature steam in the condenser 21 is remarkable. When the cooling air flow enters the front part of the air deflector 33, the contact area with the inner tank 1 increases, the flow rate of the cooling air flow slows down, and part of the heat outside the inner tank 1 can be taken away.

[0059] Reference Figures 1 to 3 , in some of the embodiments, the bottom wall of the condenser 21 is attached to the outer wall of the cold air cavity 31; the air deflector 33 is provided with an opening 331, and the outer wall of the condenser 21 is adapted to the opening 331. With such a setting, the bottom wall of the condenser 21 can directly contact the flowing cooling air flow through the opening 331, which speeds up the heat transfer and exchange speed. The flowing cooling air flow takes away more heat from the bottom wall of the condenser 21 and increases the effect of steam condensation and reflux.

[0060] Exemplarily, the shape of the opening 331 is the same as the shape of the bottom wall of the condenser 21, and the size of the opening 331 is the same as the size of the bottom wall of the condenser 21. In other embodiments, the shape of the opening 331 is the same as the shape of the bottom wall of the condenser 21, and the lower half of the condensation cavity 211 can be accommodated inside the cold air cavity 31, so that both the side wall and the bottom wall of the condenser 21 can contact the flowing cooling air flow.

[0061] Exemplarily, the opening 331 can be square, circular, diamond-shaped or other irregular shapes.

[0062] In other embodiments, the middle part of the condenser 21 is located in the opening 331 of the air deflector 33. Or the part of the condenser 21 where the air outlet is provided is located in the opening 331 of the air deflector 33. In other embodiments, part of the cavity of the condenser 21 can be located inside the cold air cavity 31 through the opening 331, so that part of the side wall and part of the bottom wall of the condensation cavity 211 can both contact the flowing cooling air flow.

[0063] In some of these embodiments, an air inlet 332 and at least one air outlet 333 are formed on the air deflector 33. The air inlet 332 and the air outlet 333 are located on both sides of the condenser 21. The air inlet 332 is formed upward, and the cooling fan 32 is installed at the air inlet 332. With such an arrangement, the air inlet 332 at the top facilitates the entry of the cooling air flow, improving the smoothness of the cooling air flow in the condensation chamber 211, thereby sufficiently dissipating the heat from the bottom of the condenser 21. The steam after temperature reduction is finally discharged from the air outlet 333 of the air deflector 33, increasing the heat dissipation effect of air cooling.

[0064] Exemplarily, the shape and size of the air inlet 332 are adapted to the cooling fan 32. The air inlet 332 is circular. The air inlet 332 is located at the rear of the heat conducting plate.

[0065] Exemplarily, there are multiple air outlets 333, and the air outlets 333 are located at the front of the heat conducting plate. The air outlets 333 are arranged in the front-back direction, facilitating the forward flow of the cooling air flow from the rear to the front to dissipate heat from the inner tank 1 and the condenser 21.

[0066] Reference Figure 2 and Figure 5 In some of these embodiments, the condensing device 2 further includes a plurality of heat dissipation members 23. The heat dissipation members 23 protrude from the bottom wall of the condenser 21. The heat dissipation members 23 are located in the cold air chamber 31. The heat dissipation members 23 extend in the direction from the air inlet 332 towards the air outlet 333. With such an arrangement, the heat dissipation fins can not only guide the cooling air flow but also increase the contact area between the cooling air flow and the condensing device 2, reducing the temperature of the bottom wall of the condenser 21 and further improving the cooling and condensation effect of the condenser 21 on the high-temperature steam.

[0067] Exemplarily, the bottom wall of the condenser 21 is a plane, and the heat dissipation members 23 are heat dissipation fins. There are three heat dissipation fins, and the three heat dissipation fins are arranged at intervals parallel to the cooling air flow direction to form an air flow channel. The height of each heat dissipation fin is the same and is less than the height of the condensation chamber 211. In other embodiments, the number of heat dissipation fins is not limited. The heights of the heat dissipation fins can also be different.

[0068] Reference Figure 1 and Figure 3 In some of these embodiments, the water supply assembly 22 is arranged on the outer wall of the inner tank 1. The water supply assembly 22 includes a water tank 221, a water inlet pipe 222, and a control valve 223. The water inlet pipe 222 connects the water tank 221 with the condensation chamber 211; the control valve 223 is installed on the water inlet pipe 222. With such an arrangement, the amount of water can be controlled in real time through the control valve 223, ensuring that the water consumption of the steam generator 4 is sufficient, the water flow in the condensation chamber 211 is continuous and does not flow out from the exhaust hole 215, thereby ensuring the condensation effect on the high-temperature steam in the condensation chamber 211.

[0069] Exemplarily, the water tank 221 is disposed on the upper surface of the inner container 1. One end of the water inlet pipe 222 communicating with the water tank 221 is higher than the end of the water inlet pipe 222 communicating with the water inlet 214, and the control valve 223 is located in the middle part of the water inlet pipe 222.

[0070] Exemplarily, when using the steam cooking device 100, if the steam generator 4 requires a large amount of water, the control valve 223 is opened. The water in the water tank 221 enters the condensation chamber 211 through the water inlet pipe 222 and the water inlet 214, then flows into the bottom wall of the condenser 21 and enters the inner container 1 through the exhaust pipe 12 to supply water to the steam generator 4. At this time, the flow rate of the water in the condensation chamber 211 is relatively fast; when the water volume in the inner container 1 begins to increase, the control valve 223 adjusts the water volume and flow rate passing through the water inlet pipe 222 to slow down the flow rate of the water on the bottom wall of the condenser 21, and so on in a cycle.

[0071] Reference Figures 1 to 3 Referring to, the steam cooking device 100 provided by the embodiment of the present disclosure further includes a housing 5. The inner container 1, the condensation device 2 and the heat dissipation device 3 are all located inside the accommodation space formed by the housing 5. The heat dissipation device 3 can discharge the cooled steam to the outside of the housing 5.

[0072] The technical features of the above-disclosed embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0073] The above-disclosed embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
