AI Technical Summary
After the existing electric water dispenser stops the discharge of water, the residual liquid in the pipeline mixes with the fresh water, causing the water temperature to drop. Especially in milk mixer products, the residual water mixes with the fresh water to have a greater impact on the water temperature and drainage.
A water outlet mechanism is designed, and a channel switching valve is used to control the passage between the pump body and the pipeline. The switching valve makes the pump body work when the first passage is cut off, and residual water is discharged, thereby improving the accuracy of the water temperature and drainage at the outlet.
By discharging residual water, the water temperature and drainage accuracy of the pump body's outlet end are improved, ensuring the stability of the outlet temperature and good hygiene conditions.

Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, and particularly relates to a water outlet mechanism and an electric water dispenser. Background Art
[0002] Household appliances with the function of heating water (such as water boilers, warm water machines, and milk warmers, etc.), generally realize the function of discharging water out through a water pump and pipelines. However, when the drainage stops, there is still liquid water inside the pipelines. When the user uses the function of discharging water out next time, the newly heated water with a higher temperature will be mixed with the remaining water with a lower temperature, resulting in a lower water outlet temperature. Especially for products such as milk warmers, the temperature of the water heated by them is not high (for example, warm water at 75°C, 55°C or 45°C) and the drainage volume is not much (usually the water outlet volume is between 100 ml and 300 ml). The influence of the mixing of the remaining water and the newly heated water on the water temperature and the drainage volume is even greater.
[0003] Therefore, further improvement is needed. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and to provide a water outlet mechanism and an electric water dispenser, which can improve the water temperature at the water outlet end of the pump body and the drainage volume accuracy.
[0005] The purpose of the utility model is realized as follows:
[0006] A water outlet mechanism includes a pump body and a first pipeline for water inlet. A first passage is formed between the pump body and the first pipeline. A passage switching valve is arranged on the first passage, and the passage switching valve can make the first passage conduct or cut off.
[0007] The passage switching valve is also connected with a second pipeline that can communicate with the external environment. A second passage is formed between the pump body and the second pipeline. The passage switching valve can make the second passage conduct and the first passage cut off, or the passage switching valve can make the first passage conduct and the second passage cut off.
[0008] The water outlet end of the pump body is connected with a third pipeline, and the water outlet end of the third pipeline is connected with a water outlet. The water outlet can communicate with the second pipeline or the first pipeline through the second passage or the first passage.
[0009] As a specific scheme, the other end of the second pipeline relative to the passage switching valve is connected with a check valve, and the check valve conducts along the direction from it to the second pipeline and cuts off in the reverse direction.
[0010] As a specific scheme, the passage switching valve is an electromagnetic valve device.
[0011] As a specific solution, the channel switching valve has a first interface, a second interface, a third interface, and a switching component for controlling the connection between the third interface and the first interface or the second interface. The first interface is connected to the first pipeline, the second interface is connected to the second pipeline, and the third interface is connected to the pump body.
[0012] An electric water dispenser includes a kettle body and the above-mentioned water outlet mechanism, and the water outlet end of the kettle body is connected to the water inlet end of the first pipeline.
[0013] As a specific solution, the kettle body has a water storage cavity, and a heating device capable of heating the water storage cavity is provided on the kettle body.
[0014] As a specific solution, the switching valve is arranged below the kettle body, the water outlet end of the kettle body is arranged on the lower side of the kettle body, and the first pipeline extends downward from the water outlet end of the kettle body.
[0015] The beneficial effects of the present utility model are as follows:
[0016] By setting the switching valve, the pump body can work when the first passage is truncated, so that the residual water at the water outlet end of the pump body can be discharged outward, improving the water temperature and the drainage volume accuracy at the water outlet end of the pump body. Description of the Drawings
[0017] Figure 1 It is a schematic structural diagram of an embodiment of the present utility model.
[0018] Figure 2 It is a schematic diagram of the working state of an embodiment of the present utility model Figure 1 。
[0019] Figure 3 It is a schematic diagram of the working state of an embodiment of the present utility model Figure 2 。 Detailed Embodiments
[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0021] Referring to Figures 1 - 3 , this water outlet mechanism includes a pump body 1 and a first pipeline 21 for water inlet. A first passage is formed between the pump body 1 and the first pipeline 21. A channel switching valve 3 is provided on the first passage, and the channel switching valve 3 can make the first passage conduct or truncate.
[0022] The channel switching valve 3 is also connected to a second pipeline 22 that can communicate with the external environment. A second passage is formed between the pump body 1 and the second pipeline 22. The channel switching valve 3 can make the second passage conduct and the first passage cut off, or the channel switching valve 3 can make the first passage conduct and the second passage cut off. When it is necessary to drain the residual water, the passage switching valve 3 will switch to the state where the second passage conducts and the first passage cuts off, that is, during the process of the pump body 1 draining water, air pressure can be supplemented from the second passage, ensuring that the pump body 1 can drain the residual water more smoothly to the outside.
[0023] The water outlet end of the pump body 1 is connected to a third pipeline 23, and the water outlet end of the third pipeline 23 is connected to a water outlet 5. The water outlet 5 can communicate with the second pipeline 22 or the first pipeline 21 through the second passage or the first passage. The water outlet 5 can be used to provide warm water to the outside or drain the residual water to the outside.
[0024] When the previous water outlet is completed, the switching valve 3 immediately switches the first passage from the conducting state to the cut-off state. At this time, the pump body 1 continues to work. Since the first passage is cut off, no new water will enter the water outlet end of the pump body 1 when the pump body 1 continues to work, and it is discharged from the water outlet 5 through the third pipeline 23. The residual water at the water outlet end of the pump body 1 is discharged to the outside under the action of the pump body 1.
[0025] By setting the switching valve 3, the pump body 1 can work when the first passage is cut off and the second passage is conducting, enabling the residual water at the water outlet end of the pump body 1 to be discharged to the outside, improving the water temperature and the drainage volume accuracy at the water outlet end of the pump body 1. Moreover, after the drainage operation, the growth rate of bacteria in the third pipeline 23 can be relatively reduced, making the sanitary condition of the water discharged from the water outlet 5 better.
[0026] Further, the other end of the second pipeline 22 relative to the channel switching valve 3 is connected to a check valve 4. The check valve 4 conducts along the direction from it to the second pipeline 22 and cuts off in the reverse direction. The check valve 4 can prevent part of the water from flowing from the second pipeline 22 to the external environment during use, ensuring that the water outlet mechanism does not leak water in the working environment (such as inside an electric water dispenser).
[0027] Further, the channel switching valve 3 is an electromagnetic valve device, which is convenient to control the channel switching valve 3 through an electric control device, improving the working accuracy of the channel switching valve 3.
[0028] Further, the channel switching valve 3 has a first interface 31, a second interface 32, a third interface 33, and a switching component (not marked in the figure) for controlling the connection between the third interface 33 and the first interface 31 or the second interface 32. The first interface 31 is connected to the first pipeline 21, the second interface 32 is connected to the second pipeline 22, and the third interface 33 is connected to the pump body 1.
[0029] Such as Figure 2As shown, when it is necessary to discharge new water from the kettle lift 6, the first interface 31 and the third interface 33 are conducted to make the first passage conducted.
[0030] As Figure 3 shown, when it is necessary to discharge residual water, the second interface 32 and the third interface 33 are conducted to make the second passage conducted.
[0031] The present utility model also discloses an electric water dispenser, which includes a kettle body 6 and the above-mentioned water outlet mechanism, and the water outlet end of the kettle body 6 is connected to the water inlet end of the first pipe 21.
[0032] Further, the kettle body 6 has a water storage cavity 61, and a heating device 62 capable of heating the water storage cavity 61 is provided on the kettle body 6.
[0033] Further, the switching valve 3 is arranged below the kettle body 6, the water outlet end of the kettle body 6 is arranged on the lower side of the kettle body 6, and the first pipe 21 extends downward from the water outlet end of the kettle body 6, so that the water outlet mechanism can make better use of the space position below the kettle lift 6, relatively reducing the overall width of the electric water dispenser. It can also relatively reduce the length of the first pipe 21, reduce the influence of the water remaining in the first pipe 21 on the water outlet temperature and accuracy to a negligible level. At the same time, it can also reduce the chance of the residual water in the first pipe 21 flowing back into the kettle lift 6.
[0034] The above embodiments are only the preferred solutions of the present utility model, and the present utility model may also have other implementation solutions. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope set by the claims of this application.
