Description

Technical Field

[0001] This utility model belongs to the field of waterway structure technology, and in particular relates to a waterway structure that can drain residual water and a water outlet device. Background Technology

[0002] In daily life, there are various water-dispensing devices with internal water circuits, such as water dispensers, water purifiers, and formula makers. Taking a water dispenser as an example, its internal water circuit structure includes a water pump, water pipes, a water outlet, and a heating element. One end of the water pipe connects to the water tank, and the other end connects all the aforementioned components in series. When dispensing water, the water pump starts, drawing water from the water tank through the water pipe into the heating element (if there is no heating element, this step is unnecessary), and finally discharging it from the water outlet. However, after the user has finished filling the water tank, a considerable amount of water remains in the water pipe. If the water remains in the water pipe for a long time, it is prone to bacterial growth and spoilage, becoming contaminated. When the user fills the water tank again, the contaminated water will enter the cup and be consumed by the human body, affecting human health. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide a water channel structure and water outlet device that can drain residual water, so as to solve the technical problem that the existing water channel structure will leave water that has not been drained, which is easy to breed bacteria and deteriorate. When water is dispensed again, the deteriorated water is discharged, which will affect human health if consumed.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A water system structure and water outlet device capable of draining residual water includes: a first set of water pipes connected to a water storage tank; a first water pump whose inlet is connected to the first set of water pipes; a second set of water pipes connected to the outlet of the first water pump; a three-way valve installed on the second set of water pipes and whose first and second ends are respectively connected to the second set of water pipes; a third set of water pipes with one end connected to the third end of the three-way valve; a second water pump installed on the third set of water pipes and whose inlet and outlet are both connected to the third set of water pipes; and a water outlet head connected to the other ends of the second and third sets of water pipes.

[0008] By setting the above structure, after the user sets the corresponding output water volume, the first water pump starts when water is discharged, drawing a portion of the water from the storage tank and transmitting it through the second set of water pipes to the outlet for discharge. When the water volume discharged from the outlet approaches the user-set water volume, the first water pump stops working, the first end of the three-way valve closes, and the second water pump starts to draw out the residual water in the second set of water pipes and output it to the outlet. This ensures that there is no residual water in the second set of water pipes, and that each water discharge is drawn from the water tank, ensuring the cleanliness of the water and protecting human health.

[0009] In some embodiments, it further includes: a heating element disposed on the second set of water pipes and located after the three-way valve, capable of overheating the water pumped from the storage tank by the first water pump;

[0010] By installing a heating element, the water entering from the second set of water pipes can be heated by the heating element and output to obtain hot water.

[0011] In some embodiments, the third set of water pipes passes through the inside of the heating element and is connected to the water outlet at the other end.

[0012] By passing the third set of water pipes through the inside of the heating element, the water discharged from the third set of water pipes to the outlet can also be heated to the same temperature as the water in the second set of water pipes.

[0013] In some embodiments, the water outlet head is provided with a first interface for connecting to the second set of water pipes and a second interface for connecting to the third set of water pipes, wherein the first interface is located above the second interface;

[0014] By optimizing the positions of the first and second interfaces, water drawn from the third set of water pipes and input into the outlet is prevented from flowing back into the first set of water pipes, thus avoiding residual water in the first set of water pipes.

[0015] In some embodiments, the water outlet is a water-air separator.

[0016] A water outlet device includes the aforementioned waterway structure capable of draining residual water;

[0017] By setting up the above-mentioned water circuit structure inside the water outlet equipment, it is ensured that there is no residual water inside the water outlet equipment, thus ensuring the cleanliness of the water and protecting human health. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] This utility model provides a water circuit structure and water outlet device that can drain residual water, including: a first set of water circuit pipes 2 connected to a water storage tank 1, a first water pump 3 whose inlet is connected to the first set of water circuit pipes 2, a second set of water circuit pipes 4 connected to the outlet of the first water pump 3, a three-way valve 5 installed on the second set of water circuit pipes 4 and whose first end 501 and second end 502 are respectively connected to the second set of water circuit pipes 4, a third set of water circuit pipes 7 whose one end is connected to the third end 503 of the three-way valve 5, a second water pump 6 installed on the third set of water circuit pipes 7 and whose inlet and outlet are both connected to the third set of water circuit pipes 7, and a water outlet head 9 connected to the other end of the second and third sets of water circuit pipes 7.

[0023] Specifically, the water effluent process is as follows:

[0024] When the user presses the corresponding water volume button (e.g., 500lm), the first end 501 of the three-way valve 5 opens, the first water pump 3 starts, and a portion of water is drawn from the water tank 1, transmitted through the second set of water pipes 4 to the water outlet 9, and then discharged into the water cup 10. When the water volume approaches 500lm, for example, 490ml of water has been discharged, the first water pump 3 stops, the first end 501 of the three-way valve 5 closes, and the second water pump 6 starts, drawing out the remaining 10ml of water in the second set of water pipes 4 and discharging it to the water outlet 9 to replenish the water cup 10. Therefore, the total amount of water output from the water outlet 9 to the water cup 10 is 500lm. This ensures that there is no residual water in the second set of water pipes 4. Each time water is dispensed, it is drawn from the water tank again. It should be noted that because the action is electronically controlled, the action is rapid, so the user will not feel the switching between the first water pump 3 and the second water pump 6.

[0025] Preferably, this application also includes a heating element 8, which is installed on the second set of water pipes 4 and located after the three-way valve 5. When the first water pump 3 is started, water from the water storage tank 1 can be drawn into the heating element 8 and sent to the outlet 9. When the water passes through the heating element 8, it is heated to a predetermined temperature and hot water is output from the outlet 9. For example, the heating element 8 can heat the water to 95 degrees Celsius.

[0026] Specifically, the first set of water pipes 2 is located between the water storage tank 1 and the first water pump 3; the second set of water pipes 4 is divided into two sections, the first section is located between the first water pump 3 and the heating element 8, and the second section is located between the heating element 8 and the outlet 9; the third set of water pipes 7 is also divided into two sections, the first section is located between the third end 503 of the three-way valve 5 and the inlet of the second water pump 6, and the second section is located between the outlet of the second water pump 6 and the outlet 9.

[0027] In the first embodiment, the third set of water pipes 7 can also pass through the interior of the heating element 8 and then be connected at one end to the water outlet 9. Specifically, the third set of water pipes 7 is made of stainless steel. The heat generated by the heating element 8 can be conducted to the outer wall of the third set of water pipes 7, and then the outer wall of the third set of water pipes 7 heats the water inside, so that the water output from the third set of water pipes 7 to the water outlet 9 can also reach 95 degrees Celsius, ensuring that the water temperature output from the water outlet 9 is the temperature set by the user.

[0028] In the second embodiment, the third set of water pipes 7 can be directly connected to the water outlet 9 without passing through the inside of the heating element 8. Specifically, during heating, when the user sets a certain water outlet temperature, the control circuit board can appropriately increase the heating temperature of the heating element 8 at that set temperature, so that the water temperature output to the water outlet 9 through the second set of water pipes is appropriately increased. When the cold water from the third set of water pipes is mixed, the user-set temperature can be obtained.

[0029] Specifically, the aforementioned water replenishment and temperature control are precisely controlled by the control circuit board.

[0030] Preferably, the water outlet 9 can be a gas-liquid separator to prevent scalding caused by air jets when outputting high-temperature water. Specifically, the gas-liquid separator includes a water outlet 901 and an air outlet 902.

[0031] Preferably, this application provides a first interface 903 and a second interface 904 on the water outlet 9. The first interface 903 is connected to the second set of water pipes 4, and the second interface 904 is connected to the third set of water pipes 7. In this way, the water output from the first interface 903 can flow directly downwards and out of the outlet 901 of the gas-liquid separator, and the water output from the second interface 904 will not flow upwards into the second set of water pipes 4 to cause secondary residual water.

[0032] A water outlet device, characterized in that it includes the above-mentioned waterway structure capable of draining residual water.

[0033] Specifically, the water outlet equipment can be a water dispenser, water purifier, formula maker, or other equipment with an internal water circuit structure. The water outlet equipment can be equipped with a water storage tank 1 that is directly connected to the first set of water circuit pipes 2.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
