Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and specifically provides a drinking water purification device. Background Art

[0002] In recent years, with the continuous improvement of people's economic level and environmental awareness, people pay more and more attention to water quality, and various types of drinking water purification equipment have been widely used. Since the water purification tank in the drinking water purification equipment plays the role of storing purified water, the sterility and antibacterial requirements of the water tank must meet safety standards.

[0003] The clean water tank is equipped with an exhaust port, which allows the purified water to be discharged under atmospheric pressure. However, it is inevitable that dust, bacteria, viruses, and other particles in the air will enter the clean water tank, causing secondary contamination. When people do not use the water purifier for extended periods of time, such as when they are away from home, the clean water in the tank is not refreshed and purified, and instead becomes a breeding ground for bacteria, causing large numbers of bacteria to grow in the clean water tank and the ice chamber.

[0004] For example, pipeline water dispensers equipped with both a clean water tank and an ice container are typically located inside the dispenser. Numerous probes are also installed on the tank, making it difficult to disassemble. This makes cleaning the tank and ice container difficult. Once bacteria grow in the tank and ice container, they become difficult to remove, affecting the quality of subsequent drinking water, adversely affecting the user's health and severely impacting the user experience. Utility Model Content

[0010] In the preferred technical solution of the above-mentioned drinking water purification equipment, the drinking water purification equipment also includes a two-inlet and one-outlet solenoid valve, a cold water outlet pipe, a hot water outlet pipe and a return pipe. The first water inlet end of the two-inlet and one-outlet solenoid valve is connected to the water outlet of the ice tank through the cold water outlet pipe, and the second water inlet end of the two-inlet and one-outlet solenoid valve is connected to the water outlet end of the heating component through the hot water outlet pipe. The water outlet end of the two-inlet and one-outlet solenoid valve is connected to the water outlet component, one end of the return pipe is connected to the third interface of the reversing valve, and the other end of the return pipe is connected to the hot water outlet pipe. The first water inlet end and the second water inlet end can both be selectively connected to the water outlet end. When the first water inlet end and the second water inlet end are not connected to the water outlet end, the water storage component, the heating component and the ice tank are connected in sequence to form the sterilization circuit.

[0011] In the preferred technical solution of the above-mentioned drinking water purification equipment, the water outlet component has a water outlet channel, and the drinking water purification equipment also includes a cold water outlet pipe, a hot water outlet pipe and a return pipe. The water outlet end of the heating component is connected to the water outlet channel through the hot water outlet pipe, and the water outlet of the ice tank is connected to the water outlet channel through the cold water outlet pipe. One end of the return pipe is connected to the third interface of the reversing valve, and the other end of the return pipe is connected to the hot water outlet pipe.

[0015] In the preferred technical solution of the above-mentioned drinking water purification device, the water outlet component is a water outlet nozzle.

[0016] In the case of adopting the above-mentioned preferred technical solution, by setting the water outlet end of the heating component or the drainage component to be selectively connected to the drain port, on the one hand, when the drinking water purification device is in the sterilization mode, the water outlet end of the heating component can be connected to the drain port, so that the water in the water storage component enters the heating component, and the hot water heated by the heating component flows back to the ice bladder through the drain port, and then returns to the water storage component, so that the drinking water purification device can be effectively sterilized, ensuring the cleanliness and sterility of the water storage component and the ice bladder, thereby ensuring the freshness and hygiene of the drinking water; on the other hand, when the drinking water purification device is sterilized or is in the drainage mode, the drainage component is connected to the drain port, which can facilitate the discharge of the water in the sterilization circuit (or the water in the ice bladder) through the drainage component, greatly improving the user experience.

[0017] Furthermore, by setting a reversing valve, it is possible to facilitate convenient switching between the sterilization mode and the drainage mode, further improving the user experience. Compared with setting the first valve and the second valve to achieve the selective connection of the water outlet end of the heating component or the drainage component with the drain port, the form of setting a reversing valve to achieve the selective connection of the water outlet end of the heating component or the drainage component with the drain port can simplify the pipeline connection and make the switching between the sterilization mode and the drainage mode of the drinking water purification equipment more convenient.

[0018] Furthermore, compared with setting the drainage component in the form of a drain pipe and a drain valve, setting the drainage component in the form of a drain nozzle and a first blocking member can avoid the use of a drain valve, thereby saving the cost of the drinking water purification equipment and further improving the user experience.

[0019] Furthermore, by setting up two inlet and one outlet solenoid valves, on the one hand, when the first water inlet end is connected with the water outlet end, the water in the ice tank can flow to the water outlet component through the cold water outlet pipe, which is convenient for users to take cold water. When the second water inlet end is connected with the water outlet end, the hot water at the water outlet end of the heating component can flow to the water outlet component through the hot water outlet pipe, which is convenient for users to take hot water. On the other hand, when the first water inlet end and the second water inlet end are not connected with the water outlet end, the water outlet end of the heating component can be connected to the drain through the return pipe, so that the water storage component, the heating component and the ice tank are connected in sequence to form a sterilization circuit, which is convenient for sterilizing the drinking water purification equipment.

[0020] Furthermore, by arranging a second blocking component to connect the water storage component, the heating component and the ice container in sequence to form a sterilization circuit, the use of a two-inlet and one-outlet valve can be avoided, thereby reducing the production cost of the drinking water purification equipment. At the same time, when the drinking water purification equipment is in the sterilization mode, hot water can also flow into the water outlet component and sterilize the interior of the water outlet component, further improving the user experience.

[0021] Furthermore, by setting up a detection component, it is possible to detect whether the second sealing component blocks the water outlet channel. When the second sealing component blocks the water outlet channel, a signal is transmitted to the reversing valve, so that the first interface of the reversing valve is switched to be connected with the third interface, so that the water storage component, the heating component and the ice chamber are connected in sequence to form a sterilization circuit. When the sterilization is completed, the second sealing component opens the water outlet channel and transmits a signal to the reversing valve, so that the first interface of the reversing valve is switched to be connected with the second interface, so that the water in the sterilization circuit can be discharged through the drainage component, thereby realizing automatic switching between the sterilization mode and the drainage mode, further improving the user experience.

[0022] Furthermore, by arranging a circulation pump on the hot water inlet pipe, on the one hand, when the drinking water purification device is in the hot water outlet mode, the circulation pump can be used to transport the water in the water storage component to the heating component, and then the hot water heated by the heating component can be transported to the water outlet component to flow out, making it convenient for users to take hot water; on the other hand, when the drinking water purification device is in the sterilization mode, the circulation pump can be used to circulate the hot water heated by the heating component in the sterilization circuit, thereby effectively sterilizing the drinking water purification device.

[0039] It should be noted that, in actual applications, those skilled in the art may configure the drinking water purification equipment as a water purifier, or may configure the drinking water purification equipment as a pipeline machine, or may configure the drinking water purification equipment as an integrated drinking water purification machine, etc. Such adjustments and changes to the specific type of drinking water purification equipment do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0040] The specific embodiment of the drinking water purification device of the present invention is described in detail below using a pipeline machine as an example.

[0041] Based on the problem mentioned in the background technology that the existing pipeline machine easily breeds bacteria in the water purification tank and the ice bladder, resulting in poor drinking water quality and thus a poor user experience, the utility model provides a drinking water purification device.

[0042] Specifically, if Figure 1 and Figure 6As shown, the drinking water purification device of the present invention includes a water storage component 1, an ice container 2, a heating component 3, a drainage component 5, a water outlet component 4 and a circulation pump 311. The ice container 2 has a water inlet 201, a water outlet 202 and a drain outlet 203.

[0043] Among them, the water storage component 1 is connected to the water inlet 201, the water outlet 202 is connected to the water outlet component 4, and the water inlet end of the heating component 3 is connected to the water storage component 1. When the drinking water purification device is in the first working state, the water outlet end of the heating component 3 can be connected to the water outlet component 4. When the drinking water purification device is in the second working state, the water outlet end of the heating component 3 or the drainage component 5 can be selectively connected to the drainage port 203.

[0044] When the water outlet of the heating component 3 is connected to the drain port 203 , the water storage component 1 , the heating component 3 and the ice container 2 are connected in sequence to form a sterilization circuit, and the circulation pump 311 is provided on the sterilization circuit.

[0045] Through such an arrangement, that is, by arranging the water outlet end of the heating component 3 or the drainage component 5 to be selectively connected to the drain outlet 203, on the one hand, when the drinking water purification device is in the sterilization mode, the water outlet end of the heating component 3 can be connected to the drain outlet 203, so that the water in the water storage component 1 enters the heating component 3, and the hot water after being heated by the heating component 3 flows back to the ice bladder through the drain outlet 203, and then returns to the water storage component 1, so that the drinking water purification device can be effectively sterilized, ensuring the cleanliness and sterility of the water storage component 1 and the ice bladder, thereby ensuring the freshness and hygiene of the drinking water; on the other hand, when the drinking water purification device is sterilized or in the drainage mode, the drainage component 5 is connected to the drain outlet 203, which can facilitate the discharge of the water in the sterilization circuit (or the water in the ice bladder 2) through the drainage component 5, greatly improving the user experience.

[0046] It should be noted that, in actual applications, those skilled in the art may configure the water storage component 1 as a water tank, or as a water tank, or as any other possible form, and so on. Such adjustments and changes to the specific setting type of the water storage component 1 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0047] Preferably, the water storage member 1 is a water storage tank.

[0048] It should be noted that, in actual application, the present invention does not impose any limitation on the specific setting type of the heating component 3. For example, the heating component 3 can be set as an instant heating module, or the heating component 3 can be set as a heating water tank, or the heating component 3 can be set as an electromagnetic heating module, and so on. Such adjustments and changes to the specific setting type of the heating component 3 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0049] Preferably, the heating component 3 is an instant heating module.

[0050] Through such a setting, the heating component 3 is set as an instant heating module, which can quickly heat the water transported to the heating component 3 and improve the heating efficiency. It can not only improve the hot water output efficiency, but also improve the sterilization efficiency, further enhancing the user experience.

[0051] It should be noted that the present invention does not impose any limitation on the specific connection method for the water outlet end of the heating component 3 or the drainage component 5 to be selectively connected to the drain outlet 203. As long as the water outlet end of the heating component 3 or the drainage component 5 can be selectively connected to the drain outlet 203, etc., such adjustments and changes to the specific connection method for the water outlet end of the heating component 3 or the drainage component 5 to be selectively connected to the drain outlet 203 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0052] In a specific embodiment, Figure 1 and Figure 6 As shown, the drinking water purification device also includes a reversing valve 6, the first interface of the reversing valve 6 is connected to the drain outlet 203, the second interface of the reversing valve 6 is connected to the drain component 5, and the third interface of the reversing valve 6 is connected to the water outlet end of the heating component 3. The first interface can be selectively connected to the second interface or the third interface.

[0053] By providing the reversing valve 6, it is possible to conveniently switch between the sterilization mode and the drainage mode, further improving the user experience.

[0054] In another specific embodiment, the water outlet end of the heating component 3 is connected to the drain outlet 203 through a first pipeline, and the drainage component 5 is connected to the drain outlet 203 through a second pipeline (not shown in the figure). The drinking water purification device also includes a first valve and a second valve. The first valve is arranged on the first pipeline and is used to control the on and off of the first valve. The second valve is arranged on the second pipeline and is used to control the on and off of the second valve.

[0055] It should be noted that, although both of the above two embodiments can realize the selective communication between the water outlet end of the heating component 3 or the drainage component 5 and the drain outlet 203, compared with the form of setting the first valve and the second valve, the form of setting the reversing valve 6 to realize the selective communication between the water outlet end of the heating component 3 or the drainage component 5 and the drain outlet 203 can simplify the pipeline connection and make the switching between the sterilization mode and the drainage mode of the drinking water purification equipment more convenient.

[0056] Of course, preferably, the drinking water purification device also includes a reversing valve 6, the first interface of the reversing valve 6 is connected to the drain outlet 203, the second interface of the reversing valve 6 is connected to the drain component 5, and the third interface of the reversing valve 6 is connected to the water outlet end of the heating component 3. The first interface can be selectively connected to the second interface or the third interface.

[0057] It should be noted that, in practical applications, the present invention does not impose any limitation on the specific configuration type of the drainage component 5 , as long as it can drain the water in the sterilization circuit or the ice chamber 2 .

[0058] In a specific embodiment, Figure 1 and Figure 6 As shown, the drainage component 5 includes a drainage nozzle 51 and a first blocking component 52 . The drainage nozzle 51 has a drainage channel. The first blocking component is adapted to the drainage channel and can open or close the drainage channel.

[0059] When the drinking water purification device is in the water outlet mode, the first blocking component 52 blocks the drain nozzle 51 to prevent the water in the ice bladder 2 from being discharged through the drain nozzle 51. When the drinking water purification device is in the drainage mode, the first blocking component 52 opens the drain nozzle 51, and the water in the sterilization circuit (or the water in the ice bladder 2) is discharged through the drain nozzle 51, thereby realizing convenient switching between the water outlet mode and the drainage mode.

[0060] It should be noted that, in actual applications, those skilled in the art may set the first sealing member 52 to a silicone plug that is compatible with the drain nozzle 51, or may set the first sealing member 52 to a rubber plug that is compatible with the drain nozzle 51, or may set the first sealing member 52 to include a plug and a sealing ring arranged outside the plug, etc. Such adjustments and changes to the specific setting type of the first sealing member 52 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0061] Preferably, the first blocking member 52 is a silicone plug adapted to the drain nozzle 51 .

[0062] In another specific embodiment, the drainage component 5 includes a drainage pipe and a drainage valve (not shown in the figure). The drainage valve is arranged on the drainage pipe and is used to control the on-off of the drainage pipe.

[0063] When the drinking water purification device is in the water outlet mode, the drain valve is closed to prevent the water in the ice bladder 2 from being discharged through the drain pipe. When the drinking water purification device is in the drainage mode, the drain valve is opened to allow the water in the ice bladder 2 to be discharged through the drain pipe, thereby facilitating the convenient switching of the drinking water purification device between the water outlet mode and the drainage mode.

[0064] It should be noted that although the above two embodiments can drain the water in the sterilization circuit or the ice container 2, compared with setting the drainage component 5 in the form of a drain pipe and a drain valve, setting the drainage component 5 in the form of a drain nozzle 51 and a first blocking member can avoid the use of a drain valve, thereby saving the cost of the drinking water purification equipment and further improving the user experience.

[0065] It should also be noted that, when the water outlet end of the heating component 3 is connected to the drain outlet 203, the present invention does not impose any restrictions on the specific formation method of the water storage component 1, the heating component 3 and the ice container 2 being connected in sequence to form a sterilization circuit. As long as the water storage component 1, the heating component 3 and the ice container 2 can be connected in sequence to form a sterilization circuit, etc., such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included in the protection scope of the present invention.

[0066] The drinking water purification device of the present invention is introduced below in combination with the following two embodiments.

[0067] Example 1:

[0068] like Figure 1 As shown, the drinking water purification device also includes a two-inlet and one-outlet solenoid valve 7, a cold water outlet pipe 22, a hot water outlet pipe 32 and a return pipe 8, wherein the first water inlet end of the two-inlet and one-outlet solenoid valve 7 is connected to the water outlet 202 of the ice bladder through the cold water outlet pipe 22, the second water inlet end of the two-inlet and one-outlet solenoid valve 7 is connected to the water outlet end of the heating component 3 through the hot water outlet pipe 32, the water outlet end of the two-inlet and one-outlet solenoid valve 7 is connected to the water outlet component 4, one end of the return pipe 8 is connected to the third interface of the reversing valve 6, and the other end of the return pipe 8 is connected to the hot water outlet pipe 32.

[0069] Among them, the first water inlet end and the second water inlet end can be selectively connected to the water outlet end. When the first water inlet end and the second water inlet end are not connected to the water outlet end, the water storage component 1, the heating component 3 and the ice chamber 2 are connected in sequence to form a sterilization circuit.

[0070] By setting up two inlet and one outlet solenoid valves 7, on the one hand, when the first water inlet end is connected to the water outlet end, the water in the ice bladder 2 can flow to the water outlet component 4 through the cold water outlet pipe 22, which is convenient for users to take cold water. When the second water inlet end is connected to the water outlet end, the hot water at the water outlet end of the heating component 3 can flow to the water outlet component 4 through the hot water outlet pipe 32, which is convenient for users to take hot water. On the other hand, when the first water inlet end and the second water inlet end are not connected to the water outlet end, the water outlet end of the heating component 3 can be connected to the drain port 203 through the return pipe 8, so as to facilitate the water storage component 1, the heating component 3 and the ice bladder 2 to be connected in sequence to form a sterilization circuit, thereby facilitating the sterilization of the drinking water purification equipment.

[0071] Example 2:

[0072] like Figure 6 As shown, the water outlet component 4 has a water outlet channel, and the drinking water purification device also includes a cold water outlet pipe 22, a hot water outlet pipe 32 and a return pipe 8, wherein the water outlet end of the heating component 3 is connected to the water outlet channel through the hot water outlet pipe 32, and the water outlet 202 of the ice gall 2 is connected to the water outlet channel through the cold water outlet pipe 22, one end of the return pipe 8 is connected to the third interface of the reversing valve 6, and the other end of the return pipe 8 is connected to the hot water outlet pipe 32, and the drinking water purification device also includes a cold water outlet valve 221 and a second blocking component 9, wherein the cold water outlet valve 221 is arranged on the cold water outlet pipe 22 and is used to control the on-off of the cold water outlet pipe 22, and the second blocking component 9 can open or close the water outlet channel. When the second blocking component 9 closes the water outlet channel, the water storage component 1, the heating component 3 and the ice gall 2 are connected in sequence to form a sterilization circuit.

[0073] Through such an arrangement, when the drinking water purification device is in the water outlet mode, the water heated by the heating component 3 enters the water outlet component 4, thereby facilitating the outlet of hot water. When the drinking water purification device is in the sterilization mode, the second blocking component 9 closes the water outlet channel, and the water at the water outlet end of the heating component 3 flows to the third interface of the reversing valve 6, and flows into the ice bladder 2 through the drain port 203, thereby facilitating the sterilization of the drinking water purification device.

[0074] It should be noted that, in actual applications, those skilled in the art may configure the second sealing member 9 to be a silicone plug that is compatible with the water outlet, or may configure the second sealing member 9 to be a rubber plug that is compatible with the water outlet, or may configure the second sealing member 9 to include a plug and a sealing ring arranged outside the plug, etc. Such adjustments and changes to the specific setting type of the second sealing member 9 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0075] Preferably, the second blocking member 9 is a silicone plug adapted to the water outlet.

[0076] Preferably, the drinking water purification device of the present invention further includes a detection component (not shown in the figure), which is used to detect whether the second blocking component 9 blocks the water outlet channel, and the detection component is communicatively connected to the reversing valve 6.

[0077] By setting up a detection component, it is possible to detect whether the second blocking component 9 blocks the water outlet channel. When the second blocking component 9 blocks the water outlet channel, a signal is transmitted to the reversing valve 6, so that the first interface of the reversing valve 6 is switched to be connected with the third interface, so that the water storage component 1, the heating component 3 and the ice chamber 2 are connected in sequence to form a sterilization circuit. When the sterilization is completed, the second blocking component 9 opens the water outlet channel and transmits a signal to the reversing valve 6, so that the first interface of the reversing valve 6 is switched to be connected with the second interface, so that the water in the sterilization circuit can be discharged through the drainage component 5, thereby realizing automatic switching between the sterilization mode and the drainage mode, further improving the user experience.

[0078] It should be noted that the present invention does not impose any restrictions on the specific setting type of the detection component. As long as it can detect whether the second blocking component 9 blocks the water outlet channel, etc., such adjustments and changes to the specific setting type of the detection component do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0079] In a specific embodiment, the detection component is a pressure sensor disposed in the water outlet channel. When the second blocking component 9 is inserted into the water outlet channel, the pressure sensor is squeezed. The pressure sensor receives the pressure signal and transmits it to the reversing valve 6 .

The circulating pump 311 transports the water in the water storage component 1 to the heating component 3. The hot water heated by the heating component 3 cannot flow out through the water outlet component 4, and then flows into the return pipe 8, and flows back to the ice bladder 2 through the drain port 203, and then returns to the water storage component 1 through the cold water inlet pipe 21, so as to effectively sterilize the heating component 3, the ice bladder 2, the water storage component 1, and the pipeline and valve.
