[0060] The water dispenser provided by the embodiment can make the water in the pure water tank 100 be heated before flowing into the ice tank 200 by arranging the heating device 300 on the connecting pipeline 501 for connecting the pure water tank 100 and the ice tank 200, so as to realize the sterilization purpose, thereby ensuring the water safety of the user; by arranging the first switch valve 601 on the connecting pipeline 501, the connecting pipeline 501 can be cut off through the first switch valve 601 when the water in the ice tank 200 is sufficient, so as to avoid the water in the pure water tank 100 flowing into the ice tank 200 under the action of gravity, prevent the water from being mixed between the pure water tank 100 and the ice tank 200, and further ensure the heat preservation effect and heat preservation time of the ice tank 200.

[0061] In the embodiment, the heating device 300 is an instant heating device, which can realize instant heating of the water flowing through the connecting pipeline 501, thereby meeting the demand of the user for hot water, and the heating device 300 can not store hot water, so as to avoid the water in it being repeatedly heated to affect the water quality. Exemplarily, the heating device 300 can be a thick film heating device. Of course, in other embodiments, the heating device 300 can also be a heating tank, which can also realize the above effect.

[0062] Optionally, the connecting pipeline 501 comprises a first connecting pipe 5011, a second connecting pipe 5012 and a third connecting pipe 5013, two ends of the first connecting pipe 5011 are communicated with the outlet of the pure water tank 100 and the inlet of the heating device 300 respectively; two ends of the second connecting pipe 5012 are communicated with the outlet of the heating device 300 and the inlet of the first switch valve 601 respectively; two ends of the third connecting pipe 5013 are communicated with the outlet of the first switch valve 601 and the inlet of the ice tank 200 respectively. That is, the water in the pure water tank 100 can flow into the ice tank 200 through the first connecting pipe 5011, the heating device 300, the second connecting pipe 5012, the first switch valve 601 and the third connecting pipe 5013 in turn.

[0063] As shown in Figure 1 , the water dispenser further comprises a water outlet nozzle 700, a pure water pipeline 502, a cold water pipeline 503 and a hot water pipeline 504; the outlet of the pure water tank 100 is communicated with the water outlet nozzle 700 through the pure water pipeline 502; the outlet of the ice tank 200 is communicated with the water outlet nozzle 700 through the cold water pipeline 503; the outlet of the heating device 300 is communicated with the water outlet nozzle 700 through the hot water pipeline 504. This design makes the water outlet nozzle 700 flow out water at any temperature according to the user's water demand, thereby improving the user's experience.

[0064] In this embodiment, the first switch valve 601 is a three-way reversing valve, the hot water pipeline 504 is connected in parallel with the third connecting pipe 5013, that is, the inlet of the first switch valve 601 is communicated with the outlet of the heating device 300, the first outlet of the first switch valve 601 is communicated with the inlet of the third connecting pipe 5013, and the second outlet of the first switch valve 601 is communicated with the inlet of the hot water pipeline 504. That is, the hot water in the heating device 300 can be used to provide hot water for the user to drink, and can also be used to supply water to the ice tank 200. By setting the first switch valve 601 as a three-way reversing valve, the length of the hot water pipeline 504 can be shortened, and the use of the switch valve on the hot water pipeline 504 can be omitted, thereby reducing the processing cost of the water dispenser.

[0065] Continuing to show as Figure 1 , the water dispenser further comprises a water inlet pipeline 507, the inlet of the water inlet pipeline 507 is communicated with a water supply device, and the outlet of the water inlet pipeline 507 is communicated with the inlet of the pure water tank 100, so that the water in the water supply device flows into the pure water tank 100 through the water inlet pipeline 507, thereby supplying water to the pure water tank 100. In this embodiment, the water supply device can be a filter device of the water dispenser or a water bucket storing pure water. Optionally, a second switch valve 602 is arranged on the water inlet pipeline 507 to realize the conduction and interruption of the water inlet pipeline 507.

[0066] Optionally, the first liquid level detection member 102 is arranged in the pure water tank 100 to detect the liquid level of the water in the pure water tank 100, and the first liquid level detection member 102 is in signal connection with the second switch valve 602. When the first liquid level detection member 102 detects that the liquid level of the water in the pure water tank 100 reaches the lowest liquid level, the second switch valve 602 is opened to supplement the water in the pure water tank 100, so as to avoid that the small amount of water in the pure water tank 100 affects the user's use; when the first liquid level detection member 102 detects that the liquid level of the water in the pure water tank 100 reaches the highest liquid level, the second switch valve 602 is closed to stop supplementing the water in the pure water tank 100, so as to avoid that the water in the pure water tank 100 overflows and causes waste. The first liquid level detection member 102 is a liquid level sensor, and the detection result is accurate and easy to install.

[0067] It can be understood that when the water in the pure water tank 100 reaches the lowest liquid level, the second switch valve 602 is opened to supplement the water in the pure water tank 100, so that the water that may exist in the pure water tank 100 for a long time without being used affects the water quality of the water in the pure water tank 100. To solve this problem, the water dispenser further comprises a first drainage pipeline 505 for draining the residual water in the pure water tank 100. By arranging the first drainage pipeline 505, the water in the pure water tank 100 can be drained at a regular time, so as to avoid the case that the water in the pure water tank 100 breeds bacteria after being used for a long time.

[0068] Specifically, the first connecting pipe 5011 comprises a first branch pipe 50111 and a second branch pipe 50112, the inlet of the first branch pipe 50111 is in communication with the outlet of the pure water tank 100, a third switch valve 603 is arranged at the connection position of the first branch pipe 50111 and the second branch pipe 50112, the second branch pipe 50112 and the first drainage pipeline 505 are connected in parallel, the third switch valve 603 is a three-way reversing valve, the inlet of the third switch valve 603 is in communication with the outlet of the first branch pipe 50111, the first outlet of the third switch valve 603 is in communication with the second branch pipe 50112, the second outlet of the third switch valve 603 is in communication with the first drainage pipeline 505, and the outlet of the second branch pipe 50112 is in communication with the inlet of the heating device 300. By arranging the third switch valve 603 as a three-way reversing valve, the length of the first drainage pipeline 505 can be shortened, and the use of the switch valve on the first drainage pipeline 505 can be omitted, so as to reduce the processing cost of the water dispenser.

[0069] Optionally, the first connecting pipe 5011 is provided with a first water pump 801 for pumping water in the pure water tank 100 into the heating device 300. Specifically, the first water pump 801 is arranged on the first branch pipe 50111, which can make the second branch pipe 50112 and the first water drainage pipe 505 share the first water pump 801, i.e. when the first outlet of the third switch valve 603 is connected to the inlet thereof, the first water pump 801 can pump water in the pure water tank 100 into the heating device 300; when the second outlet of the third switch valve 603 is connected to the inlet thereof, the first water pump 801 can pump water in the pure water tank 100 out, so as to avoid the existence of residual water in the pure water tank 100, which affects the water quality in the pure water tank 100 and ensures the water safety of the user.

[0070] To further avoid the water in the pure water tank 100 from breeding bacteria after long-time use, the pure water tank 100 is provided with a sterilization member 101 for regularly sterilizing the water in the pure water tank 100. In the embodiment, the sterilization member 101 is a UV lamp, which has simple structure, good sterilization effect and is convenient to install. Of course, in other embodiments, the sterilization member 101 can also be other sterilization devices capable of being applied to the water dispenser to sterilize the water in the pure water tank 100.

[0071] Continuing as shown in Figure 2 The ice tank 200 is provided with a second liquid level detection member 201 for detecting the liquid level of the water in the ice tank 200, and the second liquid level detection member 201 is signal-connected with the first switch valve 601 and the third switch valve 603. When the second liquid level detection member 201 detects that the liquid level of the water in the ice tank 200 reaches the lowest liquid level, the first outlet of the first switch valve 601 is connected to the inlet thereof, and the first outlet of the third switch valve 603 is connected to the inlet thereof, so that the water in the pure water tank 100 flows into the ice tank 200 through the first branch pipe 50111, the second branch pipe 50112, the heating device 300, the second connecting pipe 5012 and the third connecting pipe 5013 in sequence, so as to supplement water in the ice tank 200 and avoid the water in the ice tank 200 from being too little to affect the user's water use; when the second liquid level detection member 201 detects that the liquid level of the water in the ice tank 200 reaches the highest liquid level, the first switch valve 601 and the third switch valve 603 are both closed to stop the water from being supplemented into the ice tank 200, so as to avoid the water in the ice tank 200 from overflowing due to being too much and causing waste. The second liquid level detection member 201 is a liquid level sensor, which has accurate detection result and is convenient to install.

[0072] It can be understood that the water in the ice tank 200 can also breed bacteria after long-time use, which affects the water quality in the ice tank 200. To solve this problem, the water dispenser further comprises a second water drainage pipe 506 for draining residual water in the ice tank 200. By arranging the second water drainage pipe 506, the water in the ice tank 200 can be drained regularly, so as to ensure the water safety of the user.

[0073] Specifically, the cold water pipeline 503 comprises a third branch pipe 5031 and a fourth branch pipe 5032 connected with each other, the second drain pipeline 506 is connected in parallel with the fourth branch pipe 5032, and a fourth switch valve 604 is arranged at the connection position of the third branch pipe 5031 and the fourth branch pipe 5032. The fourth switch valve 604 is a three-way reversing valve, that is, the inlet of the third branch pipe 5031 is connected with the outlet of the ice tank 200, the outlet of the third branch pipe 5031 is connected with the inlet of the fourth switch valve 604, the first outlet of the fourth switch valve 604 is connected with the water outlet nozzle 700, and the second outlet of the fourth switch valve 604 is connected with the inlet of the second drain pipeline 506. By arranging the fourth switch valve 604 as a three-way reversing valve, the length of the second drain pipeline 506 can be shortened, and the use of the switch valve on the second drain pipeline 506 can be omitted, thereby reducing the processing cost of the water dispenser.

[0074] Optionally, a second water pump 802 is arranged on the third branch pipe 5031. When the first outlet of the fourth switch valve 604 is connected with the inlet thereof, the second water pump 802 can pump the water in the ice tank 200 to the water outlet nozzle 700 for use by the user; when the second outlet of the fourth switch valve 604 is connected with the inlet thereof, the second water pump 802 can pump the water in the ice tank 200 into the second drain pipeline 506, so as to avoid the existence of residual water in the ice tank 200, which affects the water quality in the ice tank 200 and ensures the water safety of the user.

[0075] Embodiment Two

[0076] The embodiment provides a water dispenser which is further improved on the basis of the first embodiment.

[0077] Figure 3 A structure schematic diagram of the water dispenser provided by the embodiment is shown. As shown in the figure, Figure 3As shown, in the present embodiment, the water dispenser further comprises a heat exchange structure 400 arranged on the connecting pipeline 501. The heat exchange structure 400 comprises a heat exchange branch pipe 410 and a water supplement branch pipe 420 in heat exchange cooperation. The inlet of the heat exchange branch pipe 410 is connected to the outlet of the pure water tank 100, and the outlet of the heat exchange branch pipe 410 is connected to the inlet of the heating device 300. The inlet of the water supplement branch pipe 420 is connected to the outlet of the heating device 300, and the outlet of the water supplement branch pipe 420 is connected to the inlet of the ice tank 200. That is, the heat exchange branch pipe 410 of the heat exchange structure 400 is connected into the first branch pipe 50111, and the water supplement branch pipe 420 of the heat exchange structure 400 is connected into the third connecting pipeline 5013. By arranging the heat exchange structure 400, the water with a lower temperature in the pure water tank 100 first flows through the heat exchange branch pipe 410 of the heat exchange structure 400 and then flows into the heating device 300, and the water with a higher temperature in the heating device 300 first flows through the water supplement branch pipe 420 of the heat exchange structure 400 and then flows into the ice tank 200. The water with a lower temperature in the heat exchange branch pipe 410 and the water with a higher temperature in the water supplement branch pipe 420 can exchange heat, which is equivalent to preheating the water flowing from the pure water tank 100 to the heating device 300 and cooling the water flowing from the heating device 300 to the ice tank 200, thereby improving the heating efficiency of the heating device 300 and the refrigeration efficiency of the ice tank 200, reducing energy consumption, and reducing the use cost of the user.

[0078] Figure 4 A first structure diagram of the heat exchange structure 400 provided in the present embodiment is shown. As shown in the diagram, Figure 4 In some embodiments, the heat exchange branch pipe 410 is a hollow tubular structure, and the water supplement branch pipe 420 is arranged in a spiral shape around the outer periphery of the heat exchange branch pipe 410. This design can increase the flow path of the water in the water supplement branch pipe 420, thereby increasing the heat exchange time of the water in the water supplement branch pipe 420 and the water in the heat exchange branch pipe 410, to further reduce the initial temperature of the water flowing into the ice tank 200.

[0079] Figure 5 A second structure diagram of the heat exchange structure 400 provided in the present embodiment is shown. As shown in the diagram, Figure 5 In some embodiments, the heat exchange branch pipe 410 and the water supplement branch pipe 420 are both hollow tubular structures, and are arranged side by side with part of the outer surfaces in contact. In this example, the heat exchange branch pipe 410 and the water supplement branch pipe 420 can both be designed as square tubular structures to increase the contact area between them, thereby ensuring the heat exchange efficiency.

[0080] Figure 6 A third structure diagram of the heat exchange structure 400 provided in the present embodiment is shown. As shown in the diagram, Figure 6As shown, in some embodiments, the heat exchange branch pipe 410 and the water supplement branch pipe 420 are both hollow tubular, and one of them is annularly arranged outside the other. This arrangement can achieve better heat exchange effect, and is convenient for processing and assembling.
