[0034] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, the descriptions such as "first" and "second" in the present utility model are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0038] In the related art, a pipeline machine includes a machine shell and a water tank, an instant heating module, an instant hot water pump, an ice tank, and an ice tank water pump arranged inside the machine shell. A whole-machine water outlet is formed on the machine shell. In the hot water output mode, the water tank, the instant hot water pump, and the instant heating module are communicated with the whole-machine water outlet, and the instant heating module performs the instant heating function to provide hot water to the user; in the cold water output mode, the water tank, the ice tank water pump, the ice tank, and the whole-machine water outlet are communicated, and the ice tank performs the refrigeration function to provide cold water to the user; in the normal temperature water output mode, the water tank, the instant hot water pump, and the instant heating module are communicated with the whole-machine water outlet, and the instant heating module does not perform the instant heating function to provide normal temperature water to the user.

[0039] However, in the above-mentioned pipeline machine, when the user uses the pipeline machine for a long time, bacteria will be generated in the ice tank and the internal pipeline. Over time, it will affect the health of the user's water use.

[0040] Therefore, the embodiment of the present utility model provides a drinking water device, which has a sterilization mode. When the drinking water device is in the sterilization mode, the heating module can heat the water, and use the hot water to sterilize the refrigeration module and the internal pipeline to ensure the health of the user's water use.

[0041] It should be noted that the drinking water device provided by the embodiment of the present utility model includes but is not limited to a pipeline machine. Here, the specific type of the drinking water device provided by the embodiment of the present utility model is not limited.

[0042] The following will introduce the embodiments of the present utility model in detail with reference to the drawings and specific embodiments.

[0043] Please refer to Figures 1 to 3 , Figure 1 which is a three-dimensional structural schematic diagram of the drinking water device provided by the embodiment of the present utility model. Figure 2Schematic diagram of the first partial structure of the drinking device provided by the embodiment of the present utility model, Figure 3 Schematic diagram of the second partial structure of the drinking device provided by the embodiment of the present utility model. As shown in the figure, the present embodiment provides a drinking device 10, which includes a housing 1. A display panel 2 is provided on the front side of the housing 1, and functional trigger buttons for realizing functions such as water outlet, temperature adjustment, and water volume control can be provided on the display panel 2.

[0044] Please refer to Figure 4 , Figure 4 Pipeline structure diagram of the drinking device provided by the embodiment of the present utility model. Of course, in order to enable water to flow out, an overall water outlet 11 is also formed on the housing 1. A water cup bracket 3 connected to the housing 1 should be provided below the overall water outlet 11. The water cup bracket 3 is used to place a water cup 20, and a hollow water draining tray 31 is formed at the top of the water cup bracket 3. Through the setting of the water draining tray 31, even if water overflows or splashes, it will not spill outside the water cup bracket 3.

[0045] In order to realize the hot water outlet mode, cold water outlet mode, and normal temperature water outlet mode of the drinking device 10, the drinking device 10 provided in this embodiment should further include a water tank 4, a heating module 5, a first water pump 6, a refrigeration module 7, and a second water pump 8. The water tank 4 is connected to the housing 1, and the heating module 5 is arranged inside the housing 1; the first water pump 6 is arranged inside the housing 1 and is connected to the heating module 5; the refrigeration module 7 is arranged inside the housing 1 and is located below the heating module 5; the second water pump 8 is arranged inside the housing 1 and is connected to the refrigeration module 7.

[0046] Among them, the drinking device 10 has a first water outlet mode and a second water outlet mode. The first water outlet mode can be understood as the hot water outlet mode or the normal temperature water outlet mode, and the second water outlet mode can be understood as the cold water outlet mode or the normal temperature water outlet mode.

[0047] Please refer to Figure 5 , Figure 5 Schematic diagram of the water flow direction when the drinking device provided by the embodiment of the present utility model is in the first water outlet mode. Among them, the arrow direction is the water flow direction. As shown in the figure, when the drinking device 10 is in the first water outlet mode, the water tank 4, the first water pump 6, the heating module 5, and the overall water outlet 11 are conducted to form a first water flow path. It should be noted that if the first water outlet mode is the hot water outlet mode, the heating module 5 performs the heating function; if the first water outlet mode is the normal temperature water outlet mode, the heating module 5 does not perform the heating function.

[0048] Furthermore, please refer to Figure 6 , Figure 6Schematic diagram of the water flow when the drinking device provided by the embodiment of the present utility model is in the second water outlet mode. Among them, the arrow direction is the water flow direction. As shown in the figure, when the drinking device 10 is in the second water outlet mode, the water tank 4, the second water pump 8, the refrigeration module 7, and the whole machine water outlet 11 are conducted to form a second water outlet flow path. It should be noted that if the first water outlet mode is the cold water outlet mode, the refrigeration module 7 performs the refrigeration function; if the first water outlet mode is the normal temperature water outlet mode, the refrigeration module 7 does not perform the refrigeration function.

[0049] In this embodiment, taking the pipeline machine as an example, it can be understood that the pipeline machine is an instant heating water dispenser. That is to say, in the pipeline machine, the water supply device connected to the water tank 4 can be a water purifier, and the water purifier is directly connected to the water supply pipeline. The above heating module 5 is an instant heating module, and the first water pump 6 is an instant heating water pump. Among them, the instant heating module can be a module integrated with a pipeline and a heating element; the refrigeration module 7 can be an ice tank, and correspondingly, the second water pump 8 is an ice tank water pump.

[0050] Since the ice tank stores water, therefore, in the normal temperature water outlet mode, if the normal temperature water flows through the second water pump 8 and the refrigeration module 7, it may cause the normal temperature water flowing into the water cup 20 to be mixed with cold water. In this way, it will affect the user experience. Thus, when the drinking device 10 provided by this embodiment is a pipeline machine, in the normal temperature water outlet mode, the formed flow path should be the above-mentioned first water outlet flow path, and the heating module 5 does not perform the heating function.

[0051] It can be understood that during the daily use of the drinking device 10, as the use time of the drinking device 10 gradually increases, bacteria will grow in the interior of the refrigeration module 7 and some pipelines. If these bacteria are not removed, it will affect the user's water use health. Based on this, the drinking device 10 provided by this embodiment also has a sterilization mode.

[0052] Please continue to combine Figure 7 , Figure 7 Schematic diagram of the water flow when the drinking device provided by the embodiment of the present utility model is in the sterilization mode. Specifically, when the drinking device 10 is in the sterilization mode, the first water pump 6, the heating module 5, and the refrigeration module 7 are conducted to form a sterilization circulation loop. That is to say, the heating module 5 is used to heat the water, and the high-temperature water after heating can be used to sterilize the refrigeration module 7 and some pipelines to ensure the water use safety of the drinking device 10.

[0053] Among them, during the sterilization process, it is necessary to make the heating module 5 heat the normal temperature water to a preset temperature or above. For example, the heating module 5 can heat the normal temperature water to at least 85°C, which can be any temperature value between 85°C and 100°C, such as 85°C, 86°C, 87°C, etc. In this embodiment, there is no limitation.

[0054] As for when the sterilization mode is executed or the execution time of the sterilization mode, etc., will be introduced in detail in the following implementation manners of the control method.

[0055] It should be noted that after the sterilization mode of the drinking water device 10 provided in this embodiment is completed, the dirty water generated during the sterilization process will exist in the above-mentioned sterilization circulation loop. Therefore, after the sterilization mode of the drinking water device 10 is completed, a drainage mode is also required.

[0056] The drainage mode can be divided into a first drainage mode and a second drainage mode. Among them, when the drinking water device 10 is in the first drainage mode, the water flow direction of the formed flow path is the same as that of the first water outlet flow path formed by the above-mentioned first water outlet mode, and at this time, the heating module 5 does not execute the heating function; when the drinking water device 10 is in the second drainage mode, the water flow direction of the formed flow path is the same as that of the second water outlet flow path formed by the above-mentioned second water outlet mode, and at this time, the refrigeration module 7 does not execute the refrigeration function.

[0057] Among them, after the sterilization mode is completed, the first drainage mode can be carried out first, and then the second drainage mode, or the second drainage mode can be carried out first, and then the first drainage mode. Here, there is no limitation on the sequence of the drainage modes.

[0058] As for the execution duration of the first drainage mode, the execution duration of the second drainage mode, and the determining factors, etc., will be introduced in detail in the following implementation manners of the control method.

[0059] Taking the pipeline machine as an example, generally, there is water stored in the refrigeration module 7. Therefore, it is possible that the water in the refrigeration module 7 leaks out. In this embodiment, in order to prevent the water in the refrigeration module 7 from leaking to the strong electrical components of the heating module 5 and causing a short circuit, etc., the heating module 5 can be arranged above the refrigeration module 7. In this way, even if the water in the refrigeration module 7 leaks, it will not flow to the heating module 5, so that the working state of the heating module 5 is normal, and the stability of the drinking water device 10 provided in this embodiment is relatively strong.

[0060] Furthermore, in order to improve the compactness of the internal structure of the drinking water device 10 provided in this embodiment, the refrigeration module 7 can be arranged directly below the heating module 5. In this way, the structural compactness of the drinking water device 10 provided in this embodiment in the horizontal direction can be improved.

[0061] Please refer to Figure 8 , Figure 8 which is a usage state diagram of the drinking water device provided by the embodiment of the present utility model. During the use of the drinking water device 10, the cleanliness of the water tank 4 cannot be guaranteed. Therefore, in order to facilitate the cleaning of the water tank 4, an installation groove 12 is formed on the housing 1. The water tank 4 is accommodated in the installation groove 12 and is detachably connected to the housing 1. The detachable connection here can be understood as that the installation groove 12 is adapted to the outer shape of the water tank 4. The water tank 4 is placed in the installation groove 12 and is connected to the pipeline connecting the external water supply device and the water tank 4.

[0062] In order to avoid external dust entering the water tank 4 to a certain extent, an opening and closing member 9 rotatably connected to the housing 1 is further provided at the position corresponding to the notch of the installation groove 12 on the housing 1; the opening and closing member 9 is used to open or close the notch of the installation groove 12. That is to say, during the daily use of the drinking water device 10, the opening and closing member 9 is closed. When the water tank 4 needs to be cleaned, the opening and closing member 9 needs to be opened. At this time, the water tank 4 can be removed for cleaning. In this way, not only can the water tank 4 be protected, but also the detachable property of the water tank 4 for cleaning can be ensured, which can improve the use performance of the drinking water device provided by this embodiment.

[0063] In order to enable the drinking water device 10 provided by this embodiment to be switched from the first water outlet mode to the sterilization mode, or, from the second water outlet mode to the sterilization mode. The drinking water device 10 provided by this embodiment further includes a sterilization control valve 110. The sterilization control valve 110 is arranged between the refrigeration module 7 and the first water pump 6, and the sterilization control valve 110 is communicated with the refrigeration module 7 through a first sterilization pipe 120, and the sterilization control valve 110 is communicated with the first water pump 6 through a second sterilization pipe 130; when the drinking water device 10 is in the sterilization mode, the sterilization control valve 110 is opened; when the drinking water device 10 is in the first water outlet mode or the second water outlet mode, the sterilization control valve 110 is closed. In this way, the drinking water device 10 provided by this embodiment can be switched from the first water outlet mode to the sterilization mode or from the second water outlet mode to the sterilization mode.

[0064] Further, in order to switch the drinking water device 10 provided in this embodiment from the sterilization mode to the first water outlet mode or the second water outlet mode, the drinking water device 10 provided in this embodiment further includes a water outlet control valve 140. The water outlet control valve 140 is located between the heating module 5 and the whole machine water outlet 11, and the water outlet control valve 140 is located between the refrigeration module 7 and the whole machine water outlet 11; the water outlet control valve 140 is connected to the heating module 5 through a first water outlet pipe 150, and the water outlet control valve 140 is connected to the heating module 5 through a second water outlet pipe 160; when the drinking water device 10 is in the first water outlet mode or the second water outlet mode, the water outlet control valve 140 is opened; when the drinking water device 10 is in the sterilization mode, the water outlet control valve 140 is closed.

[0065] In this way, the drinking water device 10 can be switched from the sterilization mode to the first water outlet mode or the second water outlet mode. Moreover, when the drinking water device is in the sterilization mode, it can prevent the high-temperature sterilization water from flowing to the whole machine water outlet 11. And when the drinking water device is in the first water outlet mode or the second water outlet mode, it can ensure that the water flowing out of the heating module 5 or the water flowing out of the refrigeration module 7 flows to the whole machine water outlet 11 for the user to use.

[0066] It can be understood that if the first water outlet pipe 150 and the second water outlet pipe 160 adopt separate pipes, then water outlet control valves 140 need to be provided on both the first water outlet pipe 150 and the second water outlet pipe 160. In this way, not only is it inconvenient to arrange the pipeline, but also the overall structural compactness inside the drinking water device 10 will be reduced, and the manufacturing cost of the drinking water device 10 will be increased.

[0067] Based on this, in this embodiment, the first water outlet pipe 150 includes a first pipe section 151 and a second pipe section 152 connected together. The first pipe section 151 is connected to the heating module 5, and the second pipe section 152 is connected to the water outlet control valve 140; the second water outlet pipe 160 includes a third pipe section 161 and a fourth pipe section 162 connected together. The third pipe section 161 is connected to the refrigeration module 7, and the fourth pipe section 162 is connected to the water outlet control valve 140; wherein, the first pipe section 151 and the third pipe section 161 are connected and communicated, the second pipe section 152 and the fourth pipe section 162 are the same pipe section, and the water outlet control valve 140 is arranged on this pipe section.

[0068] In this way, not only can the water flow direction of the drinking water device 10 in the sterilization mode and the first water outlet mode or the second water outlet mode be realized, but also by sharing part of the pipe sections of the first water outlet pipe 150 and the second water outlet pipe 160 and arranging the water outlet control valve 140 on this pipe section, not only can the overall structural compactness of the drinking water device 10 provided in this embodiment be improved, but also the manufacturing cost of the drinking water device 10 provided in this embodiment is relatively low.

[0069] In order to enable the connection between the water tank 4 and the first water pump 6 when the drinking water device 10 is in the first water outlet mode, the drinking water device 10 provided in this embodiment further includes a water inlet pipe 170, and the water inlet pipe 170 is connected between the water tank 4 and the second sterilization pipe 130.

[0070] In this way, when the drinking water device 10 is in the first water outlet mode, not only can the connection and conduction between the water tank 4 and the first water pump 6 be realized, but also the water inlet pipe 170 is connected to the second sterilization pipe 130. Thus, when the drinking water device 10 is in the first water outlet mode, the first water flow path is: water tank 4 → water inlet pipe 170 → second sterilization pipe 130 → first water pump 6 → heating module 5 → first pipe section 151 → second pipe section 152 → water outlet control valve 140 → whole machine water outlet 11. Compared with the sterilization circulation loop formed when the drinking water device 10 is in the sterilization mode: first water pump 6 → heating module 5 → first pipe section 151 → third pipe section 161 → refrigeration module 7 → first sterilization pipe 120 → sterilization control valve 110 → second sterilization pipe 130 → first water pump 6, not only can the first pipe section 151 be shared, but also a part of the second sterilization pipe 130 can be shared.

[0071] In this way, the structural compactness inside the drinking water device 10 provided in this embodiment can be further improved, and the manufacturing cost of the drinking water device 10 can be further reduced. In addition, when the number of pipelines is small, that is to say, the number of pipeline joints is also small. Thus, during the water flow, the sealing performance of each loop can be improved to a certain extent to avoid water leakage during the water flow to a certain extent. Therefore, the service performance of the drinking water device 10 provided in this embodiment can be improved.

[0072] Furthermore, in order to enable the connection between the water tank 4 and the second water pump 8 when the drinking water device 10 is in the second water outlet mode, the drinking water device 10 provided in this embodiment further includes a first cold water pipe 180 and a second cold water pipe 190. The first cold water pipe 180 is connected between the second sterilization pipe 130 and the second water pump 8; the second cold water pipe 190 is connected between the second water pump 8 and the first sterilization pipe 120.

[0073] Thus, when the drinking water device 10 is in the second water outlet mode, not only can the connection and conduction between the water tank 4 and the second water pump 8 be achieved, but also the first cold water pipe 180 is connected to the second sterilization pipe 130, and the second cold water pipe 190 is connected to the first sterilization pipe 120. Therefore, when the drinking water device 10 is in the second water outlet mode, the second water outlet flow path is: water tank 4 → water inlet pipe 170 → second sterilization pipe 130 → first cold water pipe 180 → second water pump 8 → second cold water pipe 190 → first sterilization pipe 120 → refrigeration module 7 → third pipe section 161 → fourth pipe section 162 → water outlet control valve 140 → whole machine water outlet 11. Compared with the sterilization circulation loop formed when the drinking water device 10 is in the sterilization mode: first water pump 6 → heating module 5 → first pipe section 151 → third pipe section 161 → refrigeration module 7 → first sterilization pipe 120 → sterilization control valve 110 → second sterilization pipe 130 → first water pump 6, not only can the third pipe section 161 be shared, but also parts of the first sterilization pipe 120 and the second sterilization pipe 130 can be shared.

[0074] In this way, the structural compactness inside the drinking water device 10 provided in this embodiment can be further improved, and the manufacturing cost of the drinking water device 10 can be further reduced. In addition, when the number of pipelines is small, that is to say, the number of pipeline joints is also small. Thus, during the water flow process, the sealing performance of each loop can be improved to a certain extent to avoid water leakage during the water flow process to a certain extent. Therefore, the service performance of the drinking water device 10 provided in this embodiment can be improved.

[0075] In some alternative embodiments, in order to further simplify the pipeline layout inside the drinking water device 10 provided in this embodiment, the drinking water device 10 provided in this embodiment may further include a water circuit board 200 disposed on the machine shell 1; the first sterilization pipe 120, the second sterilization pipe 130, the first cold water pipe 180, and the second cold water pipe 190 are all integrated within the water circuit board 200. In this way, by using the structure of the water circuit board 200 itself, the first sterilization pipe 120, the second sterilization pipe 130, the first cold water pipe 180, and the second cold water pipe 190 can be integrated together. On the one hand, the pipeline layout difficulty inside the drinking water device 10 is reduced, and on the other hand, the occupied space of the pipelines inside the drinking water device 10 can be reduced to improve the structural compactness inside the drinking water device 10 provided in this embodiment.

[0076] Since the sterilization control valve 110 needs to be connected to the first sterilization pipe 120 and the second sterilization pipe 130, setting the sterilization control valve 110 close to the water circuit board 200 can further improve the structural compactness inside the drinking water device 10 provided in this embodiment. Therefore, in the specific implementation of this embodiment, the sterilization control valve 110 is in contact with the water circuit board 200, and the sterilization control valve 110 is located below the water circuit board 200 and beside the refrigeration module 7. Such an arrangement can centrally arrange the pipeline components (including each control valve) inside the drinking water device 10. On the one hand, it improves the convenience of arranging the pipeline components, and on the other hand, it can improve the structural compactness of the drinking water device 10 provided in this embodiment.

[0077] Of course, in order to realize the connection between the water tank 4 and an external water supply device, such as a water purifier, a water supply pipe 210 is also connected to the water tank 4. The water supply pipe 210 is used to connect the water tank 4 and a water supply device for supplying water into the water tank 4. An inlet control valve 220 is provided on the water supply pipe 210; when the drinking water device 10 is in the first water outlet mode and the second water outlet mode, the inlet control valve 220 is opened; when the drinking water device 10 is in the sterilization mode, the inlet control valve 220 is closed. Of course, when the drinking water device 10 is in the first drainage mode and the second drainage mode, the inlet control valve 220 is also in the open state.

[0078] In this way, through the setting of the inlet control valve 220, the drinking water device 10 provided in this embodiment can effectively switch between various modes.

[0079] It should be noted that in this embodiment, the above-mentioned inlet control valve 220 can be arranged at two intervals along the extension direction of the water supply pipe 210. That is to say, when one of the inlet control valves 220 fails, the other inlet control valve 220 can still work normally to ensure the normal use of the drinking water device 10.

[0080] Furthermore, in some specific implementation manners, the above-mentioned sterilization control valve 110, the water outlet control valve 140, and the inlet control valve 220 are all solenoid valves. Here, the specific types of the sterilization control valve 110, the water outlet control valve 140, and the inlet control valve 220 are not limited.

[0081] Please refer to Figure 9 , Figure 9 which is the flowchart of the control method for the drinking water device provided by the embodiment of the present invention. This embodiment also provides a control method for a drinking water device, which is applicable to the drinking water device 10 in the above-mentioned implementation manner. The control method includes:

[0082] S101. When a sterilization instruction is received, control the drinking water device 10 to switch from the first water outlet mode or the second water outlet mode to the sterilization mode, and start the heating module 5 to heat the water in the sterilization circulation loop. Here, the heating module 5 needs to heat the water in the sterilization circulation loop to the preheating temperature. In this embodiment, the preset temperature is at least 85°C.

[0083] Among them, there are two ways of sterilization reminders. One is that the sterilization indicator light on the display panel 2 flashes, and the other is to remind on the corresponding application (ApplicatioN1, APP) on the user's mobile phone. After the user receives this reminder, the high-temperature sterilization function of the drinking water device 10 needs to be started.

[0084] There are also two ways to trigger the high-temperature sterilization function. One is to long-press the sterilization button on the display panel 2, and the other is to directly trigger it on the APP. In this way, the drinking water device 10 can receive the sterilization instruction.

[0085] Generally, after the user purchases the drinking water device 10, N1 days after the first use, the first sterilization reminder will be received. After the first sterilization is completed, N1 days later, the second sterilization reminder will be received. After the second sterilization is completed, N1 days later, the third sterilization reminder will still be received. In this way, as the usage time of the drinking water device 10 increases, the number of sterilizations will also increase to ensure the water supply safety of the drinking water device 10.

[0086] It should be noted that in the specific implementation manner of this embodiment, N1 above can take the value of 30. Here, the value of N1 is not specifically limited.

[0087] As can be seen from the above, after the sterilization is completed, drainage is required. Therefore, after controlling the drinking water device 10 to switch from the first water outlet mode or the second water outlet mode to the sterilization mode, it further includes:

[0088] S102. Control the drinking water device 10 to switch from the sterilization mode to the first drainage mode or the second drainage mode; where: when the drinking water device 10 is in the first drainage mode, the water tank 4, the first water pump 6, the heating module 5, and the whole machine water outlet 11 are conducted to form a first drainage flow path, and the heating module 5 does not perform the heating function; when the drinking water device 10 is in the second drainage mode, the water tank 4, the second water pump 8, the refrigeration module 7, and the whole machine water outlet 11 are conducted to form a second drainage flow path, and the refrigeration module 7 does not perform the refrigeration function.

[0089] Specifically, the above first drainage flow path is: water tank 4 → water inlet pipe 170 → second sterilization pipe 130 → first water pump 6 → heating module 5 → first pipe section 151 → second pipe section 152 → water outlet control valve 140 → whole machine water outlet 11;

[0090] The second drainage flow path described above is: water tank 4 → water inlet pipe 170 → second sterilization pipe 130 → first cold water pipe 180 → second water pump 8 → second cold water pipe 190 → first sterilization pipe 120 → refrigeration module 7 → third pipe section 161 → fourth pipe section 162 → water outlet control valve 140 → whole machine water outlet 11.

[0091] It should be noted that after the sterilization mode lasts for N2 minutes, drainage will be carried out. In the specific implementation manner of this embodiment, the value of N2 can be 9, and the value of N2 depends on parameters such as the water capacity of the refrigeration module 7, the water capacity of the heating module 5, the heating power of the heating module 5, the water flow rate, and the water temperature. Therefore, the value of N2 is not limited here.

[0092] Of course, there are also limitations on the duration of the first drainage mode and the second drainage mode. Primarily, the duration of the first drainage mode depends on the water storage capacity in the heating module 5, and the duration of the second drainage mode depends on the water storage capacity of the refrigeration module 7. The durations of the first drainage mode and the second drainage mode are not limited here.

[0093] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
