[0049] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0050] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

"And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0053] See also Figure 1 The embodiment of the present application provides a drinking water device 1000, which generally includes a drinking water machine, a water purifier, a campus machine, etc., and the embodiment of the present application does not specifically limit this. The drinking water device 1000 may include a housing, a hot tank 100, a warm water pipeline, and a water supply pipeline 400.

[0054] Specifically, an installation space (not shown in the figure) is provided in the shell, and the hot tank 100 and at least part of the warm water pipeline are installed in the installation space, so that the shell protects the hot tank 100 and the warm water pipeline. The embodiment of the present application does not specifically limit the material used for the shell. For example, the material used for the shell can be but is not limited to plastic material and stainless steel material. At the same time, the design of the shell of the drinking water device 1000 also combines ergonomic principles to improve the user experience. For example, control components such as water extraction buttons and power switches are designed on the shell to facilitate user access and operation, so that the user can control various functions of the drinking water device 1000 through the control components.

[0055] The warm water pipeline includes a warm water tank 200 and a first water temperature detection member 60. The warm water tank 200 can be used to provide normal temperature water to the user or the hot tank 100. The first water temperature detection member 60 is used to detect the water temperature in the warm water tank 200. The water supply pipeline 400 includes a water supply port and a filtering system. The water supply port is arranged on the housing to facilitate access to raw water. The water supply port is connected to the filtering system. After the raw water is filtered by the filtering system, the water filtered by the filtering system is supplied to the warm water tank 200 to realize water supply to the warm water tank 200.

[0056] Specifically, the warm water pipeline further includes a warm water outlet pipe and a warm water outlet valve arranged on the warm water outlet pipe, a water inlet is arranged on the housing, and the warm water outlet pipe is connected to the water inlet. When taking warm water, the warm water outlet valve is turned on, and at this time, warm water flows out from the warm water tank 200, the warm water outlet pipe, and the warm water outlet valve from the water inlet in sequence. The warm water pipeline further includes a hot tank 100 water supply pipe connected to the hot tank 100, and the hot tank 100 water supply pipe can be directly connected to the warm water tank 200 or connected to the warm water outlet pipe, so that when the warm water tank 200 supplies water to the hot tank 100, water can flow from the warm water tank 200 through the hot tank 100 water supply pipe into the hot tank 100. It should be noted that in the embodiment where the hot tank 100 water supply pipe is connected to the warm water outlet pipe, the connection point between the hot tank 100 water supply pipe and the warm water outlet pipe is located upstream of the warm water outlet valve, and a control valve is provided on the hot tank 100 water supply pipe to control the on-off of the hot tank 100 water supply pipe, thereby cooperating with the warm water outlet valve to control the flow direction of water in the warm water tank 200.

[0057] Optionally, a water pump 201 is provided on the water supply pipe of the hot tank 100 or the warm water outlet pipe, and the start and stop of the water pump 201 are controlled to make the warm water tank 200 supply water to the hot tank 100, or stop supplying water to the hot tank 100. Exemplarily, the warm water tank 200 is directly connected to the hot tank 100 through the water supply pipe of the hot tank 100, and the water pump 201 is arranged at one end of the water supply pipe of the hot tank 100 close to the warm water tank 200, or the water pump 201 is connected to the warm water tank 200. For example, the water pump 201 is arranged at the bottom of the warm water tank 200 to facilitate smooth water pumping and ensure that the water in the warm water tank 200 is fully pumped.

[0058] The hot tank 100 may include a tank body 10, a heating element 30, and a second water temperature detection element 204. The tank body 10 is provided with a heating chamber 111. The second water temperature detection element 204 and the heating element 30 are arranged in the heating chamber 111. The heating element 30 is used to heat the water in the hot tank 100 to form hot water. The second water temperature detection element 204 is used to detect the water temperature in the hot tank 100, and the start and stop of the heating element 30 can be controlled by the signal fed back by the second water temperature detection element 204.

[0059] The tank body 10 is provided with a water outlet 131 and a water inlet 121 connected to the heating chamber 111. The water inlet 121 is connected to the hot tank water supply pipeline 202 so that water can be replenished into the heating chamber 111 through the water inlet 121. When the user takes hot water, the heated water flows out through the water outlet 131.

[0060] Specifically, the drinking water device 1000 further includes a hot water pipeline, which includes a hot water outlet valve 15 and a hot water pipe. The hot water outlet valve 15 is connected to the water inlet, one end of the hot water pipe is connected to the hot water outlet valve 15, and the other end is connected to the water outlet 131. When taking hot water, the hot water outlet valve 15 is turned on, and hot water flows out from the hot tank 100, the hot water pipe, the hot water outlet valve 15 and the water inlet in sequence. It should be noted that the housing may be provided with one or more water inlets, and the hot water outlet valve 15 and the warm water outlet valve may be connected to different water inlets or the same water inlet respectively. In the case where the hot water outlet valve 15 and the warm water outlet valve are connected to the same water inlet, the water inlet can take both warm water and hot water. By setting a common water inlet for warm water and hot water, the water inlet can be sterilized when taking hot water.

[0061] When the user uses hot water, the replenished warm water enters the hot tank 100 to push out the hot water. When the hot water in the tank body 10 is used up, the user needs to wait for the hot tank 100 to heat up again. In actual use, the hot water and warm water in the hot tank 100 mix too quickly, and the temperature of the hot water at the water outlet 131 drops quickly, especially when multiple people use water, and the demand for multiple people to use hot water continuously cannot be met.

[0062] To solve the above problems, combined with Figures 1 to 3 The hot pot 100 provided in the embodiment of the present application further includes a water retaining member 40, which is disposed in the heating chamber 111. Taking the drinking water device 1000 placed on a horizontal plane as an example, the hot pot 100 has a height direction perpendicular to the horizontal plane and a length direction and a width direction parallel to the horizontal plane.

[0063] The heating chamber 111 includes a first half chamber 112 and a second half chamber 113 arranged side by side and connected in a first direction, and optionally, the first direction is a width direction. For example, the tank body 10 is roughly cylindrical, and the plane passing through the central axis of the tank body 10 and perpendicular to the first direction divides the heating chamber 111 into a first half chamber 112 and a second half chamber 113. The water outlet 131 is connected to the first half chamber 112, and at least part of the water retaining member 40 is arranged in the second half chamber 113, and defines a water replenishment chamber 41 with the tank body 10. It can be understood that the water retaining member 40 can be made of a high temperature resistant material such as metal. The water replenishment chamber 41 is connected to the water inlet 121, and the water replenishment chamber 41 has a connecting port 42 connected to the heating chamber 111, so that the water in the warm water tank 200 flows into the water replenishment chamber 41 through the hot tank water replenishment pipeline 202, and then enters the heating chamber 111 through the connecting port 42. In the embodiment of the present application, the connecting port 42 is arranged in the second half chamber 113.

[0064] It can be understood that the water replenishment chamber 41 is connected to the heating chamber 111 through the connecting port 42, so that the water replenished into the water replenishment chamber 41 through the water inlet 121 is buffered, and is not directly mixed with the hot water outside the water replenishment chamber 41 under the obstruction of the water retaining member 40. Under the guidance of the water retaining plate, the hot water in the heating chamber 111 and the replenished water form layers to prevent the hot water and the replenished water from mixing too quickly, thereby reducing the rate of temperature drop of the hot water in the hot tank 100, which is conducive to maintaining the temperature of the hot water. Moreover, the embodiment of the present application further reduces the influence of the replenished water on the water temperature of the hot water at the water outlet 131 by setting the water outlet 131 in the first half chamber 112 and the connecting port 42 in the second half chamber 113, thereby increasing the distance between the connecting port 42 and the water outlet 131, thereby further helping to maintain the water temperature of the hot water at the water outlet 131, making it convenient for users to continuously take hot water and improving user experience.

[0065] Combination Figure 3 and Figure 4 In some embodiments, to ensure the buffering effect, the water retaining member 40 is arranged across the first half chamber 112 and the second half chamber 113. Specifically, the water retaining member 40 includes a top plate 43 and a surrounding plate 44, the top plate 43 is arranged at intervals with the bottom wall of the first half chamber 112 and the bottom wall of the second half chamber 113, the surrounding plate 44 is connected to the top plate 43 and arranged along the circumference of the top plate 43, and the surrounding plate 44 is connected to the bottom wall of the first half chamber 112 and the bottom wall of the second half chamber 113, so as to define a water replenishment chamber 41 located at the bottom of the heating chamber 111 with the top plate 43 and the tank body 10. It can be understood that the water replenishment chamber 41 is arranged at the bottom of the heating chamber 111 so that the water replenished into the water replenishment chamber 41 can further slow down the mixing effect with the hot water above the water replenishment chamber 41 under the action of gravity, and when the water outlet 131 is located above the water replenishment chamber 41, it can push the hot water to the water outlet 131 for easy access to the hot water.

[0066] The enclosure 44 includes a plurality of side panels arranged around the top plate 43 and connected to each other, and the plurality of side panels are connected to the top plate 43 and the bottom wall of the heating chamber 111. The plurality of side panels may be an integral component for ease of processing and assembly; further, the enclosure 44 and the top plate 43 may also be an integral structure to improve the integrity of the water retaining member 40, reduce the number of parts, and improve the production efficiency of the hot pot 100.

[0067] Optionally, the communication port 42 is disposed on a side of the enclosure 44 away from the water outlet 131 along the first direction, thereby further increasing the distance between the communication port 42 and the water outlet 131, and further reducing the effect of the supplementary water on the hot water temperature at the water outlet 131. Of course, in other embodiments of the present application, the communication port 42 may also be disposed on a side of the top plate 43 away from the water outlet 131 along the first direction.

[0068] In some other embodiments of the present application, the water retaining member 40 may also be arranged on the side wall of the second half chamber 113, and the enclosure 44 is connected to the side wall of the second half chamber 113. The embodiments of the present application are not described in detail here.

[0069] The following explanation is still made by taking the connection between the water retaining member 40 and the bottom wall of the heating chamber 111 as an example.

[0070] Combination Figure 3 In some embodiments, at least part of the heating element 30 is disposed on the flow path of the water from the connecting port 42 to the water outlet 131. Optionally, the heating element 30 is a heating tube. During the water replenishment process of the hot tank 100, the heating element 30 keeps heating, and the water flowing out of the connecting port 42 is heated by the heating element 30 when flowing through the heating element 30. In this way, during the water replenishment process, the heating element 30 heats the replenished water to improve the heating effect. The temperature of the heated water rises, thereby reducing the impact on the hot water temperature when mixing the water, so that the hot water temperature can be effectively maintained.

[0071] In a specific embodiment, in the height direction of the hot pot 100, there is a height difference between the water outlet 131 and the bottom wall of the first half chamber 112, part or all of the heating element 30 is located between the water outlet 131 and the connecting port 42, and the top plate 43 is located below the heating element 30. In this way, on the one hand, it can ensure that there is always water below the water outlet 131 and around the heating element 30 to prevent the heating element 30 from drying out; on the other hand, it can also make the connecting port 42 and the water outlet 131 have a height difference in the height direction of the hot pot 100, increase the distance between the connecting port 42 and the water outlet 131, and increase the amount of hot water below the water outlet 131, further reducing the impact of the water replenishment process on the water temperature of the hot water at the water outlet 131.

[0072] Please refer to Figures 3 to 5In one embodiment, the hot tank 100 further includes a water replenishment temperature sensor 50, which is connected to the tank body 10 and is at least partially located in the water replenishment chamber 41. The water replenishment temperature sensor 50 is used to detect the water temperature in the water replenishment chamber 41, so as to control the start and stop of the water pump 201 and realize step-by-step water replenishment. Specifically, when the heating element 30 heats the water in the heating chamber 111 to a preset temperature, the hot tank 100 enters a heat preservation state, so that the water in the heating chamber 111 and the water replenishment chamber 41 is kept at a relatively high temperature level. When the user takes water, hot water flows out from the water outlet 131, and the water level in the heating chamber 111 drops. When the water level in the heating chamber 111 drops to a certain level, the water pump 201 starts to allow the water in the warm water tank 200 to enter the water replenishment chamber 41 through the hot tank water replenishment pipeline 202 and the water inlet 121. During the water replenishment process, the replenished water mixes with the hot water in the water replenishment chamber 41, and the water temperature decreases. When the water replenishment temperature sensor 50 detects that the water temperature has dropped to a certain level, the water pump 201 is controlled to stop running, thereby stopping the water replenishment into the water replenishment chamber 41. During the water replenishment process, the heating element 30 keeps heating, and when the water temperature in the water replenishment chamber 41 rises to a certain level, the water pump 201 is controlled to start replenishing water. This cycle repeats several times until the water level in the heating chamber 111 reaches the high water level, the heating element 30 heats the water to the set temperature, and the hot tank 100 enters the insulation state. In this embodiment, a water replenishment temperature sensor 50 is set to detect the water temperature in the water replenishment chamber 41, and the water replenishment is controlled according to the signal of the water replenishment temperature sensor 50. Such step-by-step water replenishment can effectively maintain the hot water temperature in the heating chamber 111 by heating layer by layer, thereby continuously providing hot water, reducing the waiting time for getting hot water, and improving the user experience.

[0073] It should be noted that the hot tank 100 includes a first water temperature detection member 60 and a first water level detection member 70. The first water temperature detection member 60 is used to detect the hot water temperature in the heating chamber 111. Optionally, the first water temperature detection member 60 is connected to the tank body 10 and is arranged above the heating member 30. The first water level detection member 70 includes a hot water low water level probe 71, a hot water middle water level probe 72, a hot water high water level probe 73 and a hot water warning water level probe 74, which are respectively used to detect the hot water low water level, the hot water middle water level, the hot water high water level and the hot water warning water level in the heating chamber 111. Specifically, the hot water low water level probe 71, the hot water middle water level probe 72, the hot water high water level probe 73 and the hot water warning water level probe 74 extend from the top of the tank body 10 into the heating chamber 111, and the depth of extension decreases successively. Combined with the above description, when the hot water level in the heating chamber 111 does not reach the hot water high water level, the above-mentioned step-by-step method is used to replenish water. After one step-by-step water replenishment, when the water temperature of the water replenishment chamber 41 rises to a certain degree, for example, when the water temperature rises to a preset temperature, the next step-by-step water replenishment is started. When the water level in the heating chamber 111 rises to the high water level of the hot water by continuous step-by-step water replenishment, the water replenishment is stopped, and the heating element 30 heats the water to the preset temperature and then enters the heat preservation state.

[0074] Reference Figure 4 and Figure 5 In one embodiment, the water replenishment temperature sensor 50 is disposed through the connecting port 42, and is partially located in the water replenishment chamber 41. It can be understood that the flow area of ​​the connecting port 42 is larger than the cross-sectional area of ​​the water replenishment temperature sensor 50, so that when the water replenishment temperature sensor 50 is disposed through the connecting port 42, the connecting port 42 still has a sufficient flow area for water to flow from the water replenishment chamber 41 to the heating chamber 111. For example, the connecting port 42 is a strip opening opened on the side of the water retaining member 40, and the portion of the water replenishment temperature sensor 50 disposed through the connecting port 42 is roughly cylindrical, and the outer diameter of the water replenishment temperature sensor 50 is smaller than the width of the connecting port 42, and is much smaller than the length of the connecting port 42, so that the connecting port 42 has a sufficient flow area. In this way, without affecting the water replenishment process, the number of openings of the water retaining member 40 is reduced, the processing steps are reduced, and the processing efficiency is improved.

[0075] In another embodiment, the water retaining member 40 is provided with a position-avoiding port, which connects the water replenishing chamber 41 and the heating chamber 111 and exists independently of the connecting port 42. The water replenishing temperature sensor 50 is arranged through the position-avoiding port and is partially located in the water replenishing chamber 41. The position-avoiding port can be arranged on the same side of the connecting port 42, or the position-avoiding port and the connecting port 42 can be arranged on both sides of the water retaining member 40, which is not limited in the embodiment of the present application.

[0076] In the embodiment of the present application, in order to facilitate the construction of the overall flow path of the drinking water device 1000, the tank body 10 includes a tank body 11, a hot tank water outlet pipe 13 and a hot tank water inlet pipe 12. The tank body 11 defines a heating chamber 111, the water retaining member 40 is disposed in the tank body 11, the hot tank water outlet pipe 13 is installed in the tank body 11, and the hot tank water outlet pipe 13 and the first half chamber 112 are connected to form a water outlet 131, and the hot water pipe is connected to the hot tank water outlet pipe 13, so that the hot water in the heating chamber 111 can flow to the water receiving port through the hot tank water outlet pipe 13, the hot water pipe, and the hot water outlet valve 15. The hot tank water inlet pipe 12 is installed on the tank body 11, and one end of the hot tank water inlet pipe 12 extending into the heating chamber 111 is located in the water replenishing chamber 41 and has a water inlet 121. The part of the hot tank water inlet pipe 12 located outside the tank body 11 is connected to the hot tank 100 water replenishing pipe, so that the water in the warm water tank 200 can enter the water replenishing chamber 41 through the hot tank 100 water replenishing pipe and the hot tank water inlet pipe 12.

[0077] Optionally, the hot tank water outlet pipe 13 is installed on the side of the tank body 11, and the hot tank water inlet pipe 12 can penetrate into the water replenishment cavity 41 from the bottom of the tank body 11, or Figure 3As shown, in order to facilitate the arrangement of the pipelines, the hot tank water inlet pipe 12 can also penetrate into the heating chamber 111 from the side of the tank body 11, and the portion of the hot tank water inlet pipe 12 that penetrates into the heating chamber 111 is connected to the water retaining member 40, so that one end of the hot tank water inlet pipe 12 is located in the water replenishment chamber 41. The hot tank water outlet pipe 13 and the hot tank water inlet pipe 12 can be installed on the same side or different sides of the tank body 11, which is not limited in the embodiment of the present application.

[0078] In order to further meet the large demand for hot water, the drinking water device 1000 of the embodiment of the present application also has a preheating mode. Figure 1 The drinking water device 1000 further includes a hot tank return pipe 300, which is connected to both the hot tank 100 and the warm water tank 200, and is used to transport the hot water in the hot tank 100 back to the warm water tank 200. A second water temperature detection element 204 is provided in the warm water tank 200. The preheating mode is triggered before the peak water usage period. In the preheating mode, the warm water pipe transports the water in the warm water tank 200 to the hot tank 100, and the heating element 30 is turned on to heat the water in the heating chamber 111. The heated water flows back to the warm water tank 200 through the hot tank return pipe 300. This cycle is repeated until the water temperature in the warm water tank 200 reaches the preheating temperature or is within the preheating temperature range. The preheating temperature may be the same as or different from the aforementioned preset temperature, and the preset temperature may or may not fall within the preheating temperature range.

[0079] When the water usage peak arrives, the user can directly use the warm water pipeline to take the water at the preheating temperature or in the preheating temperature range, or the warm water tank 200 supplies water to the hot tank 100 through the warm water pipeline, and the hot tank 100 reheats the water to provide hot water that meets the user's needs. In this way, by preheating the water in the warm water tank 200, when the user takes hot water during the water usage peak, the hot water production time can be greatly shortened to meet the large demand for hot water.

[0080] It is understandable that the preheating mode can be turned on manually, for example, the drinking device 1000 is provided with a mode control button, and the drinking device 1000 can enter the preheating mode by operating the button, or the drinking device 1000 can automatically enter the preheating mode during a preset time period. For example, the peak water consumption period is from 8 am to 10 am, and the drinking device 1000 enters the preheating mode half an hour in advance, that is, at 7:30 am, to ensure water supply during the peak water consumption period.

[0081] In this way, the water in the warm water tank 200 is transported to the hot tank 100 through the warm water pipeline, and the hot water in the hot tank 100 is transported back to the warm water tank 200 through the hot tank return pipeline 300. A circulation is formed between the hot tank 100 and the warm water tank 200. The water temperature in the warm water tank 200 is increased by heating the hot tank 100, thereby preheating the water in the warm water tank 200. In this way, without increasing the volume and heating power of the hot tank 100, the user can obtain water of a set temperature through the warm water pipeline, and when taking hot water, the water in the warm water tank 200 can be transported to the hot tank 100 for reheating and then taken out. In a short time, the hot water production capacity can be significantly improved, the time for producing hot water can be shortened, and a large amount of hot water demand can be met while controlling costs.

[0082] Reference Figures 1 to 3 In one embodiment, the hot tank 100 is higher than the warm water tank 200, and the hot tank return pipeline 300 includes an overflow pipe of the hot tank 100, one end of the overflow pipe of the hot tank 100 is connected to the warm water tank 200, and the other end of the overflow pipe of the hot tank 100 partially penetrates into the heating chamber 111, and the end of the overflow pipe of the hot tank 100 that penetrates into the heating chamber 111 is arranged near the top of the hot tank 100. When the water level in the hot tank 100 rises to the port of the overflow pipe of the hot tank 100, the hot water in the hot tank 100 can flow back into the warm water tank 200 through the overflow pipe of the hot tank 100. In this way, not only can the hot water in the hot tank 100 be prevented from overflowing, and the safety of the drinking water device 1000 is improved, but the structure is also simple and effective, which is conducive to cost saving. Optionally, the overflow pipe of the hot tank 100 penetrates from the bottom of the hot tank 100 to smoothly flow back under the action of gravity.

[0083] It can be understood that in the height direction of the hot tank 100, one end of the overflow pipe of the hot tank 100 located in the heating chamber 111 is higher than the high water level of the hot water, so that when not in the preheating mode, the water in the heating chamber 111 can maintain the high water level of the hot water.

[0084] In another structural form not shown, the hot tank reflux pipeline 300 includes a hot tank 100 reflux pipe and a reflux control valve. One end of the hot tank 100 reflux pipe is connected to the hot tank 100, and the other end of the hot tank 100 reflux pipe is connected to the warm water tank 200. The reflux control valve is used to control the opening and closing of the hot tank 100 reflux pipe. That is, when it is necessary to keep the hot water in the hot tank 100 at a high water level, the reflux control valve is closed so that the hot water in the hot tank 100 will not flow back to the warm water tank 200 through the hot tank 100 reflux pipe; when the hot water in the hot tank 100 is about to overflow, the reflux control valve is turned on, and the hot water in the hot tank 100 can flow back to the warm water tank 200 through the hot tank 100 reflux pipe to avoid the hot water in the hot tank 100 from overflowing, thereby improving the safety of the drinking water device 1000. Of course, the reflux control valve can also be controlled to be turned on in other cases where the water in the hot tank 100 needs to flow back, and the control is more flexible.

[0085] In one embodiment, the warm water tank 200 has a second water level detection member 203, for example, the second water level detection member 203 includes a warm water high water level probe and a warm water low water level probe extending from the top to the bottom of the warm water tank 200, so as to detect the warm water high water temperature and the warm water low water level respectively. In addition, the second water level detection member 203 may also include at least one of a float type water level switch, a pressure type water level sensor, an ultrasonic water level sensor, a radar water level gauge, a photoelectric water level sensor, a capacitive water level sensor, a guided wave radar water level gauge and a probe water level sensor.

[0086] Combination Figure 1 In one embodiment, the drinking water device 1000 further includes a hot pot drainage pipeline 500, which includes a hot pot drainage pipe 501, a drain valve 502, and a steam exhaust pipe 503. The hot pot drainage pipe 501 is connected to the bottom of the heating chamber 111 so that the water in the heating chamber 111 can be drained. The drain valve 502 is arranged on the hot pot drainage pipe 501, and the drainage is controlled by controlling the opening and closing of the drain valve 502. One end of the steam exhaust pipe 503 penetrates into the heating chamber 111 and is arranged near the top of the hot pot 100, so that the steam in the heating chamber 111 can be discharged unidirectionally through the steam exhaust pipe 503.

[0087] Furthermore, the portion of the hot tank drain pipe 501 located downstream of the drain valve 502 is connected to the steam exhaust pipe 503, so that the droplets condensed in the steam exhaust pipe 503 can be discharged through the hot tank drain pipe 501, avoiding water backflow and contamination of the hot tank 100 and avoiding water accumulation in the steam exhaust pipe 503, thereby ensuring the smoothness of the steam exhaust.

[0088] Of course, the warm water tank 200 can also be drained by transporting the water in the warm water tank 200 to the heating chamber 111 and then discharging it from the hot tank drainage pipeline 500 .
