Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water equipment, and particularly relates to an up-taking water dispenser capable of recycling residual water. Background Art

[0002] The existing up-taking water dispenser includes a main machine, a water boiling device and a water taking cover. The main machine is provided with a water outlet nozzle and a water pump. The water boiling device is provided with a water storage cavity. By adding water into the water storage cavity and covering the water taking cover, the water can be heated. When the water boils, the water pump is started, and the water can be conveyed from the water storage cavity to the water outlet nozzle through a pipeline for users to drink. However, when the water pump stops, there will be residual water in the pipeline, especially between the water outlet nozzle and the water pump, which cannot be discharged. These residual waters will not only have their temperature drop and affect the taste, but also be prone to breed bacteria after a long time, which is not conducive to health. Therefore, it is very necessary to develop an up-taking water dispenser capable of recycling residual water. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an up-taking water dispenser capable of recycling residual water.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An up-taking water dispenser capable of recycling residual water includes a water boiling device, a water inlet assembly, a water outlet assembly and a water return assembly. The water boiling device is configured with a water storage cavity and a heating assembly for heating the water storage cavity. The water inlet assembly includes an upper water pipe and a water inlet pipe. The upper water pipe is arranged in the water storage cavity, and the water inlet pipe is connected to the upper water pipe. The water outlet assembly includes a water pump, a water outlet nozzle, a switch valve and a water outlet pipe. The second water inlet pipe is connected to one end of the water outlet pipe through the water pump. The water outlet nozzle is connected to the other end of the water outlet pipe through the switch valve. The switch valve can be controllably connected or disconnected between the water outlet nozzle and the water outlet pipe. The water return assembly includes an air pump, a first water return pipe, a container, a switch device and a second water return pipe. The air pump is connected to one end of the water outlet pipe close to the water outlet nozzle through the first water return pipe. The container is connected to one end of the water outlet pipe close to the water pump through the second water return pipe. The switch device is arranged on the second water return pipe, and the switch device can be opened when the air pump is started to supply water to flow into the container.

[0006] When the water dispenser with upward water intake of the present utility model closes the air pump, opens the switch valve and the water pump, the water pump guides the water in the water storage cavity to the water outlet pipe via the upper water pipe and the water inlet pipe, and then outputs it from the water outlet nozzle through the switch valve, so as to normally output water; when the air pump is opened, the switch valve and the water pump are closed, the water pump seals the water inlet pipe and the water outlet pipe, cutting off the water flow between the two. Therefore, the air pump squeezes the residual water in the water outlet pipe into the container through the second return pipe to realize the recovery of the residual water. Compared with the prior art, the water dispenser with upward water intake of the present utility model can collect the residual water in the water outlet pipe, thus avoiding the influence of the residual water on the water temperature and taste, and solving the problem that the residual water is prone to breed bacteria, making the water dispenser healthier and more reliable.

[0007] Further, the switch device is a one-way valve, the water flow direction of the one-way valve is set to flow from the water outlet pipe to the container, and the output pressure F1 of the water pump < the preset opening pressure F2 of the switch device < the output pressure F3 of the air pump; or, the switch device is set as an electromagnetic valve.

[0008] Further, the switch valve is set as a one-in-one-through electromagnetic valve, its input end is connected to the water outlet pipe, and its output end is connected to the water outlet nozzle. Or, the switch valve is set as a one-in-two-through electromagnetic valve, its input end is connected to the water outlet pipe, one of its output ends is connected to the first return pipe, and the other output end is connected to the water outlet nozzle. The switch valve can be controllably conducted to connect the first return pipe and the water outlet pipe, or conduct the water outlet nozzle and the water outlet pipe.

[0009] Further, the container is a waste water tank;

[0010] Or, a waste water pipe is connected between the switch device and the container on the second return pipe. The second return pipe can be controllably selectively conducted to the container or the waste water pipe. When the container and the second return pipe are conducted, water is output to the container. When the waste water pipe and the second return pipe are conducted, water is output to the waste water pipe. Description of the Drawings

[0015] The following is a preferred specific implementation manner of the present utility model described in conjunction with the accompanying drawings.

[0016] Refer to Figure 1 and Figure 6 , this embodiment provides an upper water intake type water dispenser capable of recycling residual water, which includes a water boiling device 1, a water inlet assembly 2, a water outlet assembly 3, and a water return assembly 4. The water boiling device 1 is configured with a water storage cavity 11 with an open upper side and a heating assembly for heating the water storage cavity 11. The water inlet assembly 2 includes an upper water pipe 21 and a water inlet pipe 22. The upper water pipe 21 is arranged in the water storage cavity 11, and the water inlet pipe 22 is connected to the upper water pipe 21. The water outlet assembly 3 includes a water pump 31, a water outlet nozzle 32, a switching valve 33, and a water outlet pipe 34. The water inlet pipe 22 is connected to one end of the water outlet pipe 34 through the water pump 31. The water outlet nozzle 32 is connected to the other end of the water outlet pipe 34 through the switching valve 33. The switching valve 33 can be controllably connected or disconnected between the water outlet nozzle 32 and the water outlet pipe 34. When the switching valve 33 connects the water outlet nozzle 32 and the water outlet pipe 34, the water outlet nozzle 32 can drain water. When the switching valve 33 disconnects the water outlet nozzle 32 and the water outlet pipe 34, the water outlet nozzle 32 closes and stops draining water.

[0017] The water return assembly 4 includes an air pump 41, a first water return pipe 42, a container 43, a switching device 44, and a second water return pipe 45. The air pump 41 is connected to one end of the water outlet pipe 34 close to the water outlet nozzle 32 through the first water return pipe 42. The container 43 is connected to one end of the water outlet pipe 34 close to the water pump 31 through the second water return pipe 45. The switching device 44 is arranged on the second water return pipe 45, and the switching device 44 can be opened when the air pump 41 starts to supply water to flow into the container 43.

[0018] In a specific implementation manner, the switching device 44 is a one-way valve, and the water flow direction of the one-way valve is set to flow from the water outlet pipe 34 to the container 43. The output pressure F1 of the water pump 31 < the preset opening pressure F2 of the switching device 44 < the output pressure F3 of the air pump 41. Through the above settings, it can be ensured that the air pump 41 outputs a large enough pressure to squeeze the water body and open the switching device 44 to collect the residual water, while the pressure output by the water pump 31 will not open the switching device 44, ensuring that the water outlet nozzle 32 can normally output the water body. In another implementation manner, the switching device 44 is set as an electromagnetic valve, and the electromagnetic valve can be controllably opened or closed, realizing opening when the air pump 41 starts to supply water to flow into the container 43, and closing when the air pump 41 is closed or the water pump 31 is opened, thereby disconnecting the container 43 from the water outlet pipe 34.

[0019] The working principle of the present utility model is as follows: When the air pump 41 is closed, the switch valve 33 is opened, and the water pump 31 is turned on, the water pump 31 guides the water in the water storage chamber 11 through the upper water pipe 21 and the water inlet pipe 22 to the water outlet pipe 34, and then outputs it from the water outlet nozzle 32 through the switch valve 33, so as to normally output water. When the air pump 41 is turned on, the switch valve 33 and the water pump 31 are closed, the water pump 31 seals the water inlet pipe 22 and the water outlet pipe 34, and cuts off the flow of water between the two. Therefore, the air pump 41 squeezes the residual water in the water outlet pipe 34 into the container 43 through the second return pipe 45 to realize the recovery of the residual water. Compared with the prior art, the up-taking water dispenser of the present utility model can collect the residual water in the water outlet pipe 34, thus avoiding the influence of the residual water on the water temperature and affecting the taste, and solving the problem that the residual water is prone to breed bacteria, making the water dispenser healthier and more reliable.

[0020] See Figure 1 , in some specific embodiments, the switch valve 33 has an input end and an output end, its input end is connected to the water outlet pipe 34, and the output end is connected to the water outlet nozzle 32, and is set as a normally open solenoid valve, for example. Or, see Figure 2 , in some specific embodiments, the switch valve 33 is set as a normally open two-way solenoid valve, its input end is connected to the water outlet pipe 34, one of its output ends is connected to the first return pipe 42, and the other output end is connected to the water outlet nozzle 32. The switch valve 33 can be controllably conducted between the first return pipe 42 and the water outlet pipe 34, or between the water outlet nozzle 32 and the water outlet pipe 34.

[0021] See Figure 1 , as an improved solution, the container 43 is a waste water tank, and the recovered residual water is treated as waste water;

[0022] Or, a waste water pipe 46 is connected between the second return pipe 45 and the container 43. The second return pipe 45 can be controllably selectively conducted to the container 43 or the waste water pipe 46. When the container 43 and the second return pipe 45 are conducted, water is output to the container 43. Since the residual water also has a certain temperature, through the above setting, this part of the residual water can be collected and applied. For example, the container 43 is set as a teapot, and the recovered residual water can be used for making tea. When the waste water pipe 46 and the second return pipe 45 are conducted, water is output to the waste water pipe 46, and the user can selectively connect the container 43 or the waste water pipe 46 according to actual needs to perform corresponding treatment on the residual water.

[0023] As an improved solution, a filtering device 411 is provided at the air inlet of the air pump 41. The filtering device 411 includes a filter element for blocking dirt in the air. The filter element is set as filter cotton. Preferably, the filter cotton is silver ion filter cotton, which has effective antibacterial and filtering properties and can effectively filter bacteria and foreign objects, such as sand, dust, insects; or, the material of the filter element includes at least one of the following materials: activated carbon, HEPA filter material, polyester non-woven fabric, polypropylene.

[0024] As an improved solution, a waterproof breathable film is provided at the air inlet of the air pump 41. The filtering accuracy of the waterproof breathable film is between ultrafiltration and nanofiltration, that is, between 0.1 micron and 0.01 micron, allowing air intake but not water leakage, thus preventing water leakage.

[0025] See Figure 1 、 Figures 3 to 6 , further including a main body 5 and a water intake cover 6. The water boiling device 1 is assembled on the side of the main body 5, and the upper side of its water storage cavity 1111 is open. The water outlet assembly 3 is arranged in the main body 5. The water inlet pipe 22 includes a first water inlet pipe 221 and a second water inlet pipe 222. The second water inlet pipe 222 is arranged in the main body 5. A first interface 51 communicating with the second water inlet pipe 23 is provided at the upper end of the main body 5. The water intake cover 6 is detachably covered on the upper end of the water storage cavity 11. The first water inlet pipe 221 is arranged inside the water intake cover 6. A second interface 61 communicating with the first water inlet pipe 221 is provided at the bottom of the water intake cover 6 corresponding to the first interface 51. The second interface 61 is detachably and sealingly connected to the first interface 51.

[0026] See Figures 3 to 6 , an installation convex portion 62 extends from the side of the water intake cover 6. A limiting groove 52 adapted to the installation convex portion 62 is provided at the upper end of the main body 5. The first interface 51 is arranged in the limiting groove 52. The second interface 61 is arranged at the bottom of the installation convex portion 62. The second interface 61 is connected to the first interface 51 as the installation convex portion 62 cooperates with the limiting groove 52. The above structure facilitates the installation and positioning of the water intake cover 6 and enables the operator to more easily align the first interface 51 and the second interface 61.

[0027] See Figure 4, a bracket 13 is provided on the side of the water storage cavity 11. The upper water pipe 21 is assembled on the bracket 13. A third interface 60 communicating with the first water inlet pipe 221 is provided at the bottom of the water intake cover 6 corresponding to the upper water pipe 21. The third interface 60 is detachably and sealingly connected to the upper end of the upper water pipe 21. Preferably, the upper water pipe 21 and the bracket 13 are of an integral structure. The upper water pipe 21 penetrates through the surface of the bracket 13 to form a port communicating with the third interface 60. The above structure in which the upper water pipe 21 and the water intake cover 6 are separable can facilitate the disassembly of the water intake cover 6 and avoid the difficulty in taking out the upper water pipe 21 due to its excessive length.
