Description

Technical Field

[0001] This invention relates to the field of water supply technology, and in particular to a water output mechanism and a water supply device. Background Technology

[0002] There are many water supply devices on the market that supply drinking water to users. These devices typically use a water outlet mechanism to dispense the water. However, when a user finishes using the water, the outlet mechanism remains full and cannot be completely drained. This residual water easily breeds bacteria, eventually contaminating the outlet mechanism. Furthermore, the next time a user uses drinking water, this residual water mixes with the newly flowing water, severely impacting the quality of the drinking water received. Therefore, further improvements are needed. Summary of the Invention

[0049] The technical solution of the present invention has the following significant beneficial effects:

[0050] 1. In this application, the first flow channel of the water output mechanism has corresponding first and second ends. When the water output mechanism is installed on a water supply device, in the water supply state, water flows from the first end of the first flow channel to the second end of the first flow channel, then flows through the second flow channel and finally flows out from the first outlet to supply the user. After the water output mechanism has finished supplying water to the user, since at least a portion of the end face of the first end is lower than the end face of the second end, and the port is connected to the first end of the first flow channel, residual water in the first flow channel can be discharged from the port, thus ensuring that there is no water residue in the first flow channel of the water output mechanism. This greatly reduces the possibility of bacterial growth in the first flow channel of the water output mechanism, ensuring that the water output by the water output mechanism does not contain any previously residual water when the user takes water next time, effectively guaranteeing the quality of the drinking water obtained by the user.

[0051] 2. When the water dispensing mechanism provides functional water to the user, since at least a portion of the end face of the first end is lower than the end face of the second end, and the port is connected to the first end of the first flow channel, residual functional water in the first flow channel can be discharged from the port, thus ensuring that no functional water remains in the first flow channel of the water dispensing mechanism. Therefore, when the user obtains ordinary drinking water or other types of functional water from the water dispensing mechanism the next time, the ordinary drinking water or other types of functional water obtained by the user will not be mixed with the previous functional water. The unique taste, flavor, or odor of the previous functional water will not affect the newly dispensed ordinary drinking water or other types of functional water, thereby allowing the user to obtain pure drinking water or other types of functional water, thus improving the user experience.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0068] In order to solve the problem that residual water in a water output mechanism can easily breed bacteria, this application proposes a water output mechanism. Figure 1 This is a schematic diagram of the water output mechanism in an embodiment of the present invention, as shown below. Figure 1As shown, the water output mechanism includes: a first flow channel 8, which has a corresponding first end and a second end. In the water supply state, water flows from the first end of the first flow channel 8 to the second end of the first flow channel 8. When the water output mechanism is installed on the water supply device, the height of at least a portion of the end face of the first end is lower than the height of the end face of the second end; a second flow channel 9, the inlet of which is connected to the first flow channel 8; a first outlet 3, which is connected to the outlet of the second flow channel 9; and a port 11, which is connected to the first end of the first flow channel 8.

[0069] In this application, the first flow channel 8 of the water output mechanism has a corresponding first end and a second end. When the water output mechanism is installed on the water supply device, in the water supply state, the water flows from the first end of the first flow channel 8 to the second end of the first flow channel 8, then flows through the second flow channel 9 and finally flows out from the first outlet 3 to supply the user. After the water output mechanism 500 completes the water supply to the user, since at least part of the end face of the first end is lower than the end face of the second end, and the port 11 is connected to the first end of the first flow channel 8, the residual water in the first flow channel 8 can be discharged from the port 11, thereby ensuring that there is no water residue in the first flow channel 8 of the water output mechanism 500 or reducing the amount of water residue in the first flow channel 8. This can greatly reduce the possibility of bacterial growth in the first flow channel 8 of the water output mechanism 500, ensuring that the water output by the water output mechanism 500 does not contain any previously residual water when the user takes water next time, effectively improving the quality of the drinking water obtained by the user.

[0070] Furthermore, when the water dispensing mechanism provides functional water to the user, since at least a portion of the end face of the first end is lower than the end face of the second end, and port 11 is connected to the first end of the first flow channel 8, residual functional water in the first flow channel 8 can be discharged from port 11, thus ensuring that no functional water remains in the first flow channel 8 of the water dispensing mechanism. In this way, when the user obtains ordinary drinking water or other types of functional water from the water dispensing mechanism the next time, the ordinary drinking water or other types of functional water obtained by the user will not be mixed with the previous functional water. The unique taste, flavor, or odor of the previous functional water will not affect the newly dispensed ordinary drinking water or other types of functional water, thereby allowing the user to obtain pure drinking water or other types of functional water, thereby improving the user experience.

[0071] To better understand the water output mechanism in this application, it will be further explained and described below. For example... Figure 1As shown, the water output mechanism may include: a first flow channel 8, a second flow channel 9, a first outlet 3, and a port 11. The first flow channel 8 may have a tendency to extend in a straight direction or a curved tendency, such as a bend; this application does not impose any limitations on it. The first flow channel 8 may have corresponding first and second ends, and the inlet of the second flow channel 9 is connected to the first flow channel 8. The first outlet 3 is connected to the outlet of the second flow channel 9.

[0072] With the above structure, in the water supply state, water can flow from the first end of the first flow channel 8 to the second end of the first flow channel 8, then enter the second flow channel 9, and finally flow out from the first outlet 3. The first end and the second end can be the ends of the first flow channel 8, or they can be not the ends of the first flow channel 8, as long as they are somewhere in the first flow channel 8. Port 11 is connected to the first end of the first flow channel 8. Port 11 is used to connect to the drain line 100 that can be switched on and off.

[0073] As a feasible option, Figure 10 This is a schematic diagram of the water supply device in an embodiment of the present invention, as shown below. Figure 10 As shown, port 11 can also be used to connect to the drinking water supply unit 200 to receive drinking water output by the drinking water supply unit 200. In the water supply state, water flowing into the first flow channel 8 can be input into the first flow channel 8 through port 11. Of course, in other feasible embodiments, the drinking water flowing into the first flow channel 8 can also be input into the first flow channel 8 from other inlets connected to the first end of the first flow channel 8, and no limitations are imposed on this application.

[0074] As a feasible option, such as Figure 10 As shown, port 11 can be used to connect to the functional water supply unit 300 in the water supply device to receive functional water output by the functional water supply unit 300. In the water supply state, functional water flowing into the first flow channel 8 can be input into the first flow channel 8 from port 11. Of course, in other feasible embodiments, functional water flowing into the first flow channel 8 can also be input into the first flow channel 8 from other inlets connected to the first end of the first flow channel 8, and no limitations are made therein in this application.

[0075] A water outlet mechanism is installed on a water supply device, through which the water supply device outputs water for user use. For example... Figure 1As shown, when the water output mechanism is installed on the water supply device, the height of at least a portion of the end face of the first end is lower than the height of the end face of the second end. Port 11 can be connected to the first end of the first flow channel 8, meaning that port 11 is positioned closer to the first end of the first flow channel 8 than the second end, and port 11 can be directly connected to the first end of the first flow channel 8. Therefore, water from the second end in the first flow channel 8 can flow to the first end, and ultimately at least a portion of the water between the first and second ends of the first flow channel 8 can be discharged from the first flow channel 8 through port 11. After the water output mechanism 500 completes the water supply to the user, the drain line 100 is opened, and at least a portion of the water between the first and second ends of the first flow channel 8 can be discharged from the first flow channel 8 through port 11 and the drain line 100, thereby reducing the residual water in the first flow channel 8 of the water output mechanism 500, or even eliminating any water residue in the first flow channel 8. This greatly reduces the possibility of bacteria growth in the first flow channel 8 of the water output mechanism 500, ensuring that the water output by the water output mechanism 500 will not contain any residual water from the previous use when the user takes water next time, effectively improving the quality of the drinking water obtained by the user.

[0076] In addition, there are many functional water supply devices on the market. These devices can supply users with different types of functional water, such as sparkling water, hydrogen-rich water, and oxygen-rich water. Of course, functional water supply devices can also generally supply users with ordinary drinking water. When functional water supply devices supply water to users, they usually use a water output mechanism 500 to finally output the water. When the user finishes using the functional water, the water output mechanism 500 is still full of functional water, and this part cannot be completely discharged. If the user next takes ordinary drinking water or other types of functional water, this part of the functional water remaining in the water output mechanism 500 will mix with the ordinary drinking water or other types of functional water and then be supplied to the user. Therefore, the drinking water obtained by the user is not completely drinking water or other types of functional water, but is mixed with the previous functional water. Especially since some functional waters have unique taste, flavor, or odor, users will feel that the water is abnormal when drinking water mixed with the previous functional water, which will affect the user experience.

[0077] After the water output mechanism 500 completes its water supply to the user, any residual functional water in the first flow channel 8 can be discharged from the port 11, ensuring that no functional water remains in the first flow channel 8 of the water output mechanism 500. This way, when the user obtains ordinary drinking water or other types of functional water from the water output mechanism 500 the next time, the obtained ordinary drinking water or other types of functional water will not be mixed with the previous functional water, avoiding cross-contamination of taste. This allows the user to obtain pure drinking water or other types of functional water, thereby improving the user experience.

[0078] Especially when the functional water is sparkling water, if a portion remains in the first flow channel 8, the next time the user obtains ordinary drinking water or other types of functional water from the water output device 500, this portion of sparkling water will mix in and make the water taste noticeably sour, seriously affecting the user experience. The user may even suspect that the functional water supply device is malfunctioning or damaged.

[0079] In order to facilitate the discharge of at least a portion of the water between the first end and the second end of the first flow channel 8 through the port 11, the port 11 may be connected to the lowest end face of the first end of the first flow channel 8, so that all the water at the first end of the first flow channel 8 can be discharged through the port 11.

[0080] As a feasible option, in the vertical plane, the bottom of the second end of the first flow channel 8 gradually decreases in height towards the bottom of the first end of the second flow channel 9. This allows the water at the second end of the first flow channel 8 to flow to the first end of the first flow channel 8, preventing accumulation in the first flow channel 8 and allowing almost all the water in the first flow channel 8 to be discharged through the port 11.

[0081] As is feasible, the first flow channel 8 can be of various shapes in the horizontal plane, including straight lines, curves, and shapes with various bends, and no limitation is made in this application.

[0082] In one specific implementation, such as Figure 1 As shown, when the water output mechanism 500 is installed on the water supply device, the extension direction of the first flow channel 8 has an angle with the horizontal line. This angle is greater than 0 degrees and less than 90 degrees. This ensures that under the action of gravity, the water at the second end of the first flow channel 8 can flow to the first end of the first flow channel 8 and thus be discharged from the first flow channel 8 through the port 11.

[0083] In one specific implementation method Figure 2 This is a three-dimensional schematic diagram of the water output mechanism in an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the water output mechanism 500 may include: a first pipe body 1, with a first flow channel 8 formed inside the first pipe body 1. In order to ensure that as much water as possible near the lower wall of the first pipe body 1 can be discharged from the port 11, the lower wall of the first pipe body 1 is inclined to the horizontal line.

[0084] The inlet of the second channel 9 can be connected to the second end of the first channel 8. In this way, after the water output mechanism 500 completes the water supply to the user, the water in the first channel 8 that does not flow into the second channel 9 can flow to the first end of the first channel 8 so as to be discharged from the port 11, which can effectively reduce the amount of water remaining in the first channel 8.

[0085] The two ends of the second flow channel 9 are respectively connected to the first flow channel 8 and the first outlet 3. The orientation of the second flow channel 9 is not limited in this application. The second flow channel 9 can extend horizontally, upwards, or downwards. Preferably, the second flow channel 9 can have a downward extension tendency. Water flowing from the first flow channel 8 into the second flow channel 9 is supplied to the user through the first outlet 3. After the water output mechanism 500 completes the water supply to the user, the water in the first flow channel 8 is discharged through port 11. Therefore, the first flow channel 8 is first connected to the atmosphere, and then the second flow channel 9 will also be connected to the atmosphere. This allows any residual water in the second flow channel 9 to automatically flow downwards under gravity, ensuring that there is no residual water in the second flow channel 9. Similarly, when the user obtains ordinary drinking water or other types of functional water from the water output mechanism 500 the next time, the obtained ordinary drinking water or other types of functional water will not be mixed with the previous functional water, thus allowing the user to obtain pure drinking water or other types of functional water, thereby improving the user experience. Of course, since the water in the second channel 9 is discharged, the amount of bacteria growing in the second channel 9 can also be reduced to some extent.

[0086] In one specific implementation, such as Figure 1 and Figure 2 As shown, the water output mechanism 500 may include: a second pipe body 2, which has a second flow channel 9. A first outlet 3 may be formed at the lower end of the second pipe body 2. The second pipe body 2 may be connected to the first pipe body 1, thereby connecting the second flow channel 9 and the first flow channel 8. In other feasible embodiments, the second pipe body 2 and the first pipe body 1 may be integrally formed.

[0087] As a feasible design, the second pipe 2 has a downward tendency, which can be vertical or inclined downward. When the water stops flowing out from the first outlet 3 formed at the lower end of the second pipe 2, the water can remain in the second pipe 2 due to surface tension. On the one hand, under the action of gravity, it may slowly drip downward later. On the other hand, when the water output mechanism 500 outputs bubble water, after the user finishes taking the bubble water, a large amount of bubble water will remain in the first flow channel 8. After the bubble water is output from the water supply device, the external pressure is normal pressure, and the bubble water will continuously release gas, which will increase the pressure in the first flow channel 8, thereby disrupting the pressure balance at the first outlet 3 of the second pipe 2. The water in the second pipe 2 will then slowly drip from the first outlet 3. Because sparkling water continuously and slowly releases gas over a considerable period of time, the first outlet 3 of the second tube 2 will also drip continuously for a considerable period, sometimes for more than ten minutes. Even after this time, dripping may continue, albeit at a significantly lower frequency, but it will not completely stop. This situation causes considerable inconvenience to users and results in a poor user experience.

[0088] Based on the above, as a feasible option, Figure 3 This is a partial cross-sectional schematic diagram of the water output mechanism with a third pipe in an embodiment of the present invention, as shown below. Figure 3 As shown, the lower part of the side wall of the second tube 2 may have a drainage section 21. The drainage section 21 is used to break the surface tension of water at the first outlet 3 of the second tube 2, so that when the user finishes taking the sparkling water, the water in the second tube 2 will flow out quickly from the first outlet 3 and will not remain in the second tube 2. In this way, there will be no water dripping at the first outlet 3.

[0089] In one feasible implementation, the drainage section 21 can have an undulating structure along the circumferential direction of the second pipe body 2 in the axial direction of the second pipe body 2. That is, the drainage section 21 can make the lower end face of the side wall of the second pipe body 2 undulate in the axial direction of the second pipe body 2, for example, in a wave-like shape. This structure can break the surface tension of water at the first outlet 3 of the second pipe body 2, and external air can also enter the second pipe body 2 from the drainage section 21, thereby allowing the water in the second pipe body 2 to flow down rapidly at the first outlet 3.

[0090] In another possible implementation, the drainage portion 21 may include one of the following: a notch, or a protrusion that protrudes downward in the axial direction of the second tube body 2. Figure 4 This is a schematic diagram of the drainage section in another embodiment of the present invention, as shown below. Figure 4As shown, when the drainage section 21 is a protrusion extending outward along the radial direction of the second pipe body 2, this structure can disrupt the surface tension of water at the first outlet 3 of the second pipe body 2, allowing external air to enter the second pipe body 2 through areas other than the protrusion, thus enabling the water in the second pipe body 2 to flow rapidly downward at the first outlet 3. There can be one, two, or more protrusions. When there are two or more protrusions, they are arranged circumferentially around the second pipe body 2.

[0091] like Figure 3 As shown, when the drainage section 21 is a notch, the notch can disrupt the surface tension of water at the first outlet 3 of the second pipe body 2, allowing external air to enter the second pipe body 2 from the outside to the inside in the radial direction, thus enabling the water in the second pipe body 2 to flow rapidly downwards at the first outlet 3. Furthermore, the length of the notch can be greater than or equal to 4 mm, and the width of the notch can be greater than or equal to 1 mm. This structure ensures that the notch disrupts the surface tension of water at the first outlet 3 of the second pipe body 2. For example, the notch can be rectangular, trapezoidal, or nearly rectangular or trapezoidal. The shape of the notch can also be rectangular at the top and trapezoidal at the bottom. This application does not specifically limit the shape of the notch; the notch only needs to be able to disrupt the surface tension of water at the first outlet 3 of the second pipe body 2, allowing the water in the second pipe body 2 to flow rapidly downwards at the first outlet 3. Similarly, there can be one, two, or more notches. When there are two or more notches, they are arranged circumferentially around the first pipe body 1.

[0092] In yet another feasible implementation, Figure 5 This is a schematic diagram of the drainage portion in another embodiment of the present invention, as shown below. Figure 5 As shown, the drainage section 21 may include a through hole formed on the side wall of the second pipe body 2, communicating with the second flow channel 9. There may be one, two, or more through holes. The through holes allow external air to enter the second flow channel 9 inside the second pipe body 2, thereby disrupting the surface tension of water at the first outlet 3 of the first pipe body 1, allowing water inside the first pipe body 1 to flow rapidly down through the first outlet 3.

[0093] In other feasible embodiments, the lower part of the side wall of the second tube 2 may have multiple different types of drainage portions 21, for example, the lower part of the side wall of the second tube 2 may have both through holes and notches or protrusions; or the lower part of the side wall of the second tube 2 may have both through holes and a structure with high and low undulations in the axial direction of the second tube 2.

[0094] Alternatively, the second tube 2 can be made of a heat-conducting material. For example, the second tube 2 can be made of metal. With the above structure, after the water in the second tube 2 is discharged through the drain 21, the inner wall of the second tube 2 can be easily dried under heating, thereby reducing the growth of bacteria on the inner wall of the second tube 2.

[0095] In order to enable the second tube 2 to be heated, as a feasible approach, Figure 6 This is a three-dimensional schematic diagram of a water output mechanism with a third pipe in an embodiment of the present invention, as shown below. Figure 3 and Figure 6 As shown, the water output mechanism may include: a third pipe 4 sleeved outside the second pipe 2, a third flow channel 10 formed between the third pipe 4 and the second pipe 2, and a second water outlet 5 formed at the lower end of the third pipe 4. The third flow channel 10 can be used to connect with the outlet of the hot water supply unit 400 to receive the hot water output by the hot water supply unit 400, thereby enabling the water output mechanism 500 to output hot water through the third flow channel 10. When the water output mechanism 500 outputs hot water, the hot water can heat the outer wall of the second pipe 2. Since the second pipe 2 can be made of a heat-conducting material, the inner wall of the second pipe 2 can also be heated to a high temperature through heat transfer. This is beneficial for the inner wall of the second pipe 2 to dry quickly. On the one hand, the dry state helps to reduce the growth of bacteria on the inner wall of the second pipe 2, and on the other hand, the high temperature can also sterilize the inner wall of the second pipe 2 to a certain extent.

[0096] As a feasible option, Figure 7 This is a partial exploded view of the third pipe of the water output mechanism in an embodiment of the present invention. Figure 8 This is a schematic diagram of the structure of the third tube body in an embodiment of the present invention. Figure 9 This is a schematic diagram of the structure of the rectifier and the water-locking component in an embodiment of the present invention, as shown below. Figures 7 to 9As shown, the third pipe body 4 includes a main body 41 and an end cap 42 connected to the lower end of the main body 41. A flow straightener 43 and a water-locking element 44 are disposed between the end cap 42 and the main body 41. Vertically, the flow straightener 43 and the water-locking element 44 are disposed within the third flow channel 10. The flow straightener 43 is used to straighten the water flowing into the third flow channel 10. The water-locking element 44 is used to lock the water in the third flow channel 10 within the third pipe body 4 when the outflow of water stops, preventing continuous dripping. Both the flow straightener 43 and the water-locking element 44 can be constructed using a filter screen. The flow straightener 43 is located upstream of the water-locking element 44. A limiting element 45 is provided between the flow straightener 43 and the water-locking element 44 to position them. The rectifier 43 is clamped and abutted by the lower end face of the body 41 and the upper end face of the limiting member 45 to achieve a limiting position. The water-locking member 44 is clamped and abutted by the lower end face of the limiting member 45 and the inner edge of the lower end of the end cap 42 to achieve a limiting position. In addition, a sealing member 46 is provided between the upper part of the inner wall of the third pipe body 4 and the second pipe body 2 to ensure that no leakage occurs in the upper part between the third pipe body 4 and the second pipe body 2.

[0097] As a feasible option, such as Figure 1 and Figure 3 As shown, in the vertical direction, the first outlet 3 can be lower than the second outlet 5. Since the second pipe body 2 is fitted with a third pipe body 4, the above structure can ensure that when the drainage part 21 breaks the surface tension of the water at the first outlet 3 of the second pipe body 2, the external air can smoothly enter the second pipe body 2, thereby causing the water in the second pipe body 2 to flow out quickly from the first outlet 3.

[0098] To achieve ultraviolet sterilization of the water flowing through the first channel 8, as a feasible method, such as... Figure 1As shown, a cylinder 6 forming a first flow channel 8 is disposed inside the first pipe body 1. One end of the cylinder 6 is connected to port 11, and the other end of the cylinder 6 is connected to the inlet of the second flow channel 9 of the second pipe body 2. The inner wall of the cylinder 6 has a reflective layer made of reflective material, or the cylinder 6 is made of reflective material. One end of the cylinder 6 is provided with an ultraviolet sterilization unit 7 for sterilizing the fluid flowing through the first flow channel 8. The ultraviolet sterilization unit 7 also seals one end of the pipe body. Water flows upward into the first pipe body 1 from port 11. The side wall of one end of the cylinder 6 has an opening, allowing water in the first pipe body 1 to flow into the cylinder 6 from the opening. The water flows along the first flow channel 8 inside the cylinder 6, and during this process, it is sterilized by the ultraviolet light emitted by the ultraviolet sterilization unit 7. Because the inner wall of the cylinder 6 has a reflective layer made of reflective material, or the cylinder 6 is made of reflective material, the ultraviolet light can be reflected inside the cylinder 6, which greatly improves the sterilization effect of the ultraviolet light. The other end of the cylinder 6 may also have an opening on its side wall. Water flowing through the first flow channel 8 flows out of the cylinder 6 and into the first pipe 1, and then immediately enters the second flow channel 9, and finally flows out from the first outlet 3 to be supplied to the user.

[0099] This application also proposes a water supply device, such as Figure 10 As shown, the water supply device includes: a water output mechanism 500 as described above; and a drain line 100 with a first on / off valve 101, which is connected to port 11. After the water output mechanism 500 completes the water supply to the user, the first on / off valve 101 can be controlled to open, thereby discharging the water remaining in the first flow channel 8 of the water output mechanism 500 through the drain line 100.

[0100] As a feasible option, such as Figure 10 As shown, the water supply device may include a functional water supply unit 300, which is capable of supplying functional water. The outlet of the functional water supply unit 300 can be connected to port 11. To achieve the connection and disconnection between the outlet of the functional water supply unit 300 and port 11, for example, a second on / off valve 301 is connected between the outlet of the functional water supply unit 300 and port 11. The water supply device has a first state and a second state. In the first state, the outlet of the functional water supply unit 300 is connected to port 11, and the first on / off valve 301 is closed. In the second state, the outlet of the functional water supply unit 300 is disconnected from port 11, and the first on / off valve 301 is connected. After the first state ends, the water supply device switches to the second state. In this way, the functional water remaining in the first flow channel 8 of the water output mechanism 500 is discharged through the drain line 100.

[0101] In the above embodiments, the functional water generated by the functional water supply unit 300 may include at least one of the following: sparkling water, oxygen-rich water, hydrogen-rich water, etc. Of course, this application does not limit the specific type of functional water.

[0102] As a feasible option, such as Figure 10 As shown, the water supply device may include a drinking water supply unit 200, which is capable of discharging drinking water. The outlet of the drinking water supply unit 200 is connected to port 11. To achieve the connection and disconnection between the outlet of the drinking water supply unit 200 and port 11, for example, a third on / off valve 201 is connected between the outlet of the drinking water supply unit 200 and port 11. The water supply device has a third state in which the outlet of the drinking water supply unit 200 is connected to port 11, and the first on / off valve 101 is closed. After the third state ends, the water supply device switches to a second state. In this way, the drinking water remaining in the first flow channel 8 of the water output mechanism 500 is discharged through the drain line 100.

[0103] As a feasible option, such as Figure 10 As shown, the water supply device may include a hot water supply unit 400, which is capable of outputting hot water. A third flow channel 10 is connected to the outlet of the hot water supply unit 400. To achieve the connection and disconnection between the outlet of the hot water supply unit 400 and the third flow channel 10, a fourth on / off valve 401 is connected between the outlet of the hot water supply unit 400 and the third flow channel 10. When hot water needs to be output from the third pipe 4, the water supply device controls the fourth on / off valve 401 to open.
