Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, specifically a water dispenser with a hot water disinfection pipe and a timed emptying function for the hot water tank. Background Technology

[0002] A water dispenser is a very practical household appliance that conveniently provides cold, hot, and warm water to meet different drinking needs. Compared to traditional kettles, water dispensers are more convenient, hygienic, and stylish, making them an essential appliance in modern homes.

[0003] A search revealed that the prior art, specifically utility model CN215016214U, discloses a water dispenser with a timed intelligent emptying function. The dispenser includes a water tank and a control chip. The water tank is connected to a drain pipe, and a drain solenoid valve is installed on a section of the drain pipe. The control chip uses a timer to periodically open or close the drain solenoid valve. A heating element is installed inside the water tank. The water tank is connected to an outlet pipe and an inlet pipe. An outlet solenoid valve and a water nozzle are sequentially installed on a section of the outlet pipe. A safety valve, an inlet solenoid valve, and a filter are also sequentially installed on the outlet pipe. This utility model can conveniently empty the water in the pipeline and replace it with fresh water through two timed methods, effectively controlling bacterial growth and ensuring the hygiene and safety of the water supply. It is also easy to operate.

[0004] However, this method still has the following drawbacks: during long-term use, scale will form on the inner wall of the water tank, which will affect the quality of the water if it is not cleaned in time. At the same time, this method empties the hot water tank by directly draining it, and the heat contained in the drained hot water cannot be effectively utilized, resulting in energy loss. Therefore, we propose a water dispenser with hot water disinfection pipes and timed emptying of the hot water tank to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figures 1-3 This utility model provides a technical solution for a water dispenser with a hot water disinfection pipe and a timed emptying function for the hot water tank: It includes a hot water tank 1, a drain pipe 2 connected to the bottom center of the hot water tank 1, and a drain valve 112 installed on a section of the drain pipe 2. The drain valve 112 controls the water flow from the drain pipe 2, making it convenient for the user to collect hot water. A first connecting pipe 3 is connected to the left side of the drain pipe 2, and a solenoid valve 111 is installed on a section of the first connecting pipe 3. When the drain valve 112 is closed and the solenoid valve 111 is open, water enters the first connecting pipe 3 through the drain pipe 2. A disinfection box 4 is connected to a section of the first connecting pipe 3, and a coil 5 is connected to the end of the first connecting pipe 3. The top of the coil 5 is connected to a water pump 6 for increasing water pressure. The output end of the water pump 6 is connected to a water supply pipe 7. The end of the water supply pipe 7 is connected to a tee pipe 13. The right end of the tee pipe 13 is connected to a fourth connecting pipe 15. A solenoid valve 114 is installed on the pipe section of the fourth connecting pipe 15. The bottom end of the fourth connecting pipe 15, located inside the hot water tank 1, is connected to a high-pressure nozzle 16. The bottom of the high-pressure nozzle 16 has several spray holes in a ring shape. Under the action of the water pump 6, water is sprayed out through the several spray holes at the bottom of the high-pressure nozzle 16. Under the impact of the water flow, the scale attached to the inner wall of the hot water tank 1 will be peeled off, thereby achieving the purpose of cleaning the inside of the hot water tank 1.

[0029] Example 2:

[0030] At the top of the hot water tank 1 and on the right side of the fourth connecting pipe 15, there is a water supply pipe 14 for replenishing clean water into the hot water tank 1. A solenoid valve 115 is installed on the section of the water supply pipe 14. The flow of water in the water supply pipe 14 can be controlled by the solenoid valve 115, thereby controlling the water supply to the hot water tank 1.

[0031] The inner wall of the hot water tank 1 is connected to a connecting block 2 331, and the end of the connecting block 2 331 is connected to a heating unit 332. The heating unit 332 can heat the water in the hot water tank 1, and then disinfect the pipe at high temperature when the water is discharged from the hot water tank 1.

[0032] The left end of the three-way pipe 13 is connected to the second connecting pipe 8, and a solenoid valve 2 113 is installed on the pipe section of the second connecting pipe 8. The bottom end of the hot water tank 1 and the right side of the drain pipe 2 are connected to the third connecting pipe 10, and a throttle valve 116 is installed on the pipe section of the third connecting pipe 10. A heat exchange pipe 9 is connected between the second connecting pipe 8 and the third connecting pipe 10, and the heat exchange pipe 9 is located inside the hot water tank 1. By opening the solenoid valve 2 113 and closing the solenoid valve 3 114, hot water in the water supply pipe 7 is introduced into the heat exchange pipe 9 to heat the clean water that is subsequently added to the hot water tank 1, thereby preventing the loss of heat energy.

[0033] The inner wall of the disinfection box 4 is connected to a connecting block 221, and the end of the connecting block 221 is connected to an ultraviolet lamp 222 for disinfecting water. The ultraviolet lamp 222 can sterilize and disinfect the water flowing in the first connecting pipe 3.

[0034] The bottom end of the third connecting pipe 10 is connected to a water storage tank 11. The bottom left side of the water storage tank 11 is connected to a water outlet pipe 12 for discharging hot water. A drain valve 117 is installed on the pipe section of the water outlet pipe 12. The water outlet of the water storage tank 11 can be easily controlled by the drain valve 117.

[0035] The inner cavity of the water storage tank 11 is connected to a connecting block 3 441, and a sleeve 442 is movably engaged between the two connecting blocks 3 441. The inner cavity of the sleeve 442 is equipped with a filter element for filtering water.

[0036] The outer wall of the sleeve 442 is provided with several filter holes 443.

[0037] Specifically, after the water in the third connecting pipe 10 is discharged into the sleeve 442, it will be filtered by the filter element. The filtered water seeps into the water storage tank 11 through the filter hole 443. At this time, the drain valve 117 is opened, and the water in the water storage tank 11 can be discharged through the water outlet pipe 12. This water can be used for irrigation and other secondary uses.

[0038] The working principle of this utility model is as follows:

[0039] When the user-set emptying time is reached, the control unit issues a drain command. First, the water in the hot water tank 1 is heated by the heating element 323. Then, the drain valve 112, solenoid valve 213 and solenoid valve 415 are closed, while solenoid valve 111 and solenoid valve 314 are opened, and the water pump 6 is started. At this time, the water in the hot water tank 1 passes through the drain pipe 2, the first connecting pipe 3, the coil 5, the water supply pipe 7 and the fourth connecting pipe 15. Under the action of the water pump 6, the water is sprayed back into the hot water tank 1 by the high-pressure nozzle 16, and the scale attached to the inner wall of the hot water tank 1 is cleaned. The whole process takes about five minutes.

[0040] Furthermore, since the water in the hot water tank 1 is heated to a high temperature, the water will disinfect the pipes at high temperature as it flows through them. At the same time, due to the setting of the ultraviolet lamp 222, when the water flows through the inner cavity of the first connecting pipe 3, it will be further sterilized by the ultraviolet lamp 222.

[0041] After cleaning, the second circulation stage begins. At this time, solenoid valve 314 is closed, solenoid valve 213 is opened, and the outlet diameter of throttle valve 116 is reduced. After two minutes, the water in hot water tank 1 is drained, and most of the water in hot water tank 1 is in coil 5 and heat exchange tube 9. Then solenoid valve 111 is closed, and water is replenished to hot water tank 1 by water supply pipe 14. Since heat exchange tube 9 is located inside hot water tank 1, the water in heat exchange tube 9 can heat the clean water replenished to hot water tank 1 through heat exchange to prevent heat loss.

[0042] After the heat exchange is completed, the water in the heat exchange tube 9 is discharged into the sleeve 442 through the third connecting pipe 10 under the action of the water pump 6, and is filtered by the filter element in the sleeve 442. After filtration, it is discharged into the water storage tank 11 through the filter hole 443. The treated water can be used for irrigation, etc. When using it, just open the drain valve 117.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
