[0002] With the improvement of people's living standards, the demand for drinking water is also increasing. Drinking water devices such as water purifiers and pipeline machines have gradually become essential drinking water facilities in people's daily lives.

[0003] Taking the pipeline machine as an example, the pipeline machine is usually provided with a cold water tank for users to take cold water. However, if the water in the cold water tank is not used for a long time, the water in the cold water tank will deteriorate due to long-term non-flow, seriously affecting the user experience. Content of the Utility Model

[0004] The utility model aims to solve at least to some extent the above technical problems, that is, to solve at least to some extent the problem that the existing drinking water device has the problem that the water in the cold water tank deteriorates due to long-term non-use, thereby affecting the user experience.

[0005] In a first aspect, the utility model provides a drinking water device, which includes a water storage member, a cold water tank, a heating member, a control valve and a detection member. The water storage member is communicated with the cold water tank to supply water to the cold water tank. The control valve is configured to selectively communicate the water inlet end of the heating member with the water storage member or the cold water tank. The detection member is used to monitor the water level change information in the cold water tank. Among them, the detection member is communicatively connected with the control valve to selectively switch the water inlet end of the heating member to communicate with the cold water tank according to the detection result of the detection member.

[0006] In a preferred technical solution of the above drinking water device, the control valve is a first reversing valve. The first interface of the first reversing valve is communicated with the water storage member. The second interface of the first reversing valve is communicated with the cold water tank. The third interface of the first reversing valve is communicated with the water inlet end of the heating member. Among them, the third interface of the first reversing valve can selectively communicate with the first interface or the second interface of the first reversing valve.

[0007] In a preferred technical solution of the above drinking water device, the detection member includes a water level detection element for real-time detection of the water level in the cold water tank; and / or, the detection member includes a camera element for taking a picture of the water level picture in the cold water tank.

[0008] In the preferred technical solution of the above drinking water device, the drinking water device further includes a first water outlet member and a second water outlet member. The first water outlet member is communicated with the water outlet end of the cold water tank and is used for outputting the cold water in the cold water tank. The second water outlet member is used for outputting the hot water in the heating member; alternatively, the drinking water device further includes a water outlet member, and the water outlet ends of the cold water tank and the heating member are both communicated with the water outlet member.

[0009] In the preferred technical solution of the above drinking water device, the water outlet end of the heating member can be selectively communicated with the second water outlet member or the water storage member. When the water outlet end of the heating member is communicated with the second water outlet member, the hot water in the heating member is output through the second water outlet member; when the water outlet end of the heating member is communicated with the water storage member, the water storage member, the cold water tank and the heating member are sequentially communicated to form a sterilization loop.

[0010] In the preferred technical solution of the above drinking water device, the drinking water device further includes a second reversing valve. The first interface of the second reversing valve is communicated with the water outlet end of the heating member. The second interface of the second reversing valve is communicated with the water outlet assembly. The third interface of the second reversing valve is communicated with the water storage member; wherein, the first interface of the second reversing valve can be selectively communicated with the second interface or the third interface of the second reversing valve.

[0011] In the preferred technical solution of the above drinking water device, the drinking water device further includes a drainage member. The drainage member is communicated with the sterilization loop and is used for draining the water in the sterilization loop.

[0012] In the preferred technical solution of the above drinking water device, the drainage member includes a drainage pipe and a drainage valve arranged on the drainage pipe. One end of the drainage pipe is communicated with the upstream end of the heating member, and the other end of the drainage pipe is communicated with the drainage port of the drinking water device.

[0013] In the preferred technical solution of the above drinking water device, the drinking water device further includes a first water pump and a second water pump. The first water pump is used for conveying the water in the cold water tank to the first water outlet member, and the second water pump is used for conveying the water in the water storage member or the cold water tank to the second water outlet member through the heating member.

[0014] In the preferred technical solution of the above drinking water device, the drinking water device further includes an exhaust pipe. One end of the exhaust pipe is communicated with the water storage member, and the other end of the exhaust pipe is communicated with the first water outlet member and / or the second water outlet member.

[0015] In the case of adopting the above-mentioned preferred technical solution, by setting the detection component, the water level change information in the cold water tank can be monitored. By setting the detection component to be communicatively connected to the control valve, when the detection component detects that the water level in the cold water tank has not changed for a long time, the control valve can switch the water inlet end of the heating component to be connected to the cold water tank, and switch to supply water to the heating component from the cold water tank, avoiding the deterioration of the water in the cold water tank due to long-term non-use, greatly improving the use safety of the drinking water device and enhancing the user experience.

[0016] Furthermore, compared with setting the control valve in the form of a first water inlet valve and a second water inlet valve, setting the control valve in the form of a first reversing valve can simplify the pipeline connection, and at the same time, it is more convenient to switch between the water inlet end of the heating component and the water storage component or the cold water tank, further enhancing the user experience.

[0017] Still further, by setting the water outlet assembly to include a first water outlet component and a second water outlet component, the cold water in the cold water tank can be output through the first water outlet component, and the hot water heated by the heating component can be output from the second water outlet component, avoiding the problem of mixed water caused by the cold water and hot water flowing out from the same water outlet component, and further improving the user experience.

[0018] Still further, by setting the water outlet end of the heating component to be selectively connected to the water outlet component or the second water outlet component, the drinking water device can be conveniently switched between the hot water output mode and the sterilization mode. When the water outlet end of the heating component is connected to the second water outlet component, the hot water heated by the heating component is output through the second water outlet component for the user to take hot water. When the water outlet end of the heating component is connected to the water storage component, a sterilization loop can be formed by connecting the water storage component, the cold water tank, and the heating component in sequence, so as to facilitate high-temperature sterilization of the water storage component, the cold water tank, and the pipelines and valves, improve the use safety of the drinking water device, and further enhance the user experience.

[0019] Still further, by setting the drainage component, the sterilized water after sterilization can be discharged from the drinking water device, further improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following takes the pipeline machine as an example to introduce in detail the specific embodiments of the drinking water device of the present invention.

[0032] Based on the problem that the water in the cold water tank of the existing pipeline machine mentioned in the background technology deteriorates due to the long-term non-use of the water in the cold water tank, the present invention provides a drinking water device.

[0033] Specifically, please refer to Figure 1 , Figure 1 which is a schematic connection structure diagram of the drinking water device of the present invention. Figure 1 .

[0034] As Figure 1 shown, the drinking water device of the present invention includes a water storage member 1, a cold water tank 2, a heating member 3, a control valve, and a detection member 21. The water storage member 1 is communicated with the cold water tank 2 to supply water to the cold water tank 2. The control valve can selectively connect the water inlet end of the heating member 3 with the water storage member 1 or the cold water tank 2. The detection member 21 is used to monitor the water level change information in the cold water tank 2. The detection member 21 is communicatively connected with the control valve to selectively switch the water inlet end of the heating member 3 to be connected with the cold water tank 2 according to the detection result of the detection member 21.

[0035] Through such a setting, that is, by setting the detection member 21 to be able to monitor the water level change information in the cold water tank 2, and by setting the detection member 21 to be communicatively connected with the control valve, when the detection member detects that the water level in the cold water tank 2 has not changed for a long time, the control valve can switch the water inlet end of the heating member 3 to be connected with the cold water tank 2, and switch to supply water to the heating member 3 by the cold water tank 2, avoiding the deterioration of the water in the cold water tank 2 due to long-term non-use, greatly improving the use safety of the drinking water device, and enhancing the user experience.

[0036] It should be noted that in practical applications, those skilled in the art can set the heating member 3 as an instant heating module, or can also set the heating member 3 as a resistive heating module, or can also set the heating member 3 as an electromagnetic heating module, etc. Such adjustments and changes to the specific setting type of the heating member 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.

[0037] Preferably, the heating member 3 is an instant heating module.

[0038] It should be noted that the present utility model does not make any limitation on the specific setting form of the water storage member 1. For example, the water storage member 1 can be set as a water storage tank, or the water storage member 1 can also be set as a water storage tank, etc. Such adjustments and changes to the specific setting type of the water storage member 1 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.

[0039] Preferably, the water storage member 1 is a water storage tank.

[0040] Specifically, the water storage member 1 is communicated with the cold water tank 2 through a cold water inlet pipe 12, and a cold water inlet valve 121 is arranged on the cold water inlet pipe 12. When the cold water tank 2 needs to be filled with water, the cold water inlet valve 121 is opened, and the water in the water storage member 1 flows into the cold water tank 2 through the cold water inlet pipe 12.

[0041] It should be noted that the present utility model does not make any limitation on the specific setting type of the control valve, as long as the water inlet end of the heating member 3 can be selectively communicated with the water storage member 1 or the cold water tank 2.

[0044] It should be noted that although the above two embodiments can both realize the selective communication between the water inlet end of the heating member 3 and the water storage member 1 or the cold water tank 2, compared with the form of setting the control valve as the first water inlet valve and the second water inlet valve, setting the control valve as the first reversing valve 5 can simplify the pipeline connection and is more convenient for switching between the water inlet end of the heating member 3 and the water storage member 1 or the cold water tank 2.

[0045] Specifically, as Figure 1As shown, the first interface of the first reversing valve 5 is connected to the water storage member 1 through the first water inlet pipe 51, the second interface of the first reversing valve 5 is connected to the cold water tank 2 through the second water inlet pipe 52, and the third interface of the first reversing valve 5 is connected to the water inlet end of the heating member 3 through the hot water inlet pipe 53.

The detection member 21 transmits the detection result to the controller, and the controller switches the control valve to connect the water inlet end of the heating member 3 to the cold water tank 2 according to the detection result of the detection member 21. Or, the detection member 21 and the control valve can also be set to be communicatively connected to the user's mobile device (such as a mobile phone, a tablet). The detection member 21 transmits the detection result to the user's mobile device, and the user queries the detection result through the mobile device terminal and controls the control valve to switch the water inlet end of the heating member 3 to be connected to the cold water tank 2, etc. Such adjustments and changes to the connection manner between the detection member 21 and the control valve 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.

[0050] Preferably, the drinking water device further includes a controller (not shown in the figure), and the detection member 21 and the control valve are both communicatively connected to the controller.

[0051] It should be noted that in practical applications, those skilled in the art can set the cold water in the cold water tank 2 and the hot water heated by the heating member 3 to flow out from the same water outlet member, or the water outlet assembly can also be set to include two water outlet members, and the cold water in the cold water tank 2 and the hot water heated by the heating member 3 flow out from the two water outlet members respectively, etc. Such flexible adjustments and changes 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.

[0057] Through such a setting, the drinking water device can be conveniently switched between the hot water output mode and the sterilization mode. In the case where the water outlet end of the heating member 3 is communicated with the second water outlet member 42, the hot water heated by the heating member 3 is output through the second water outlet member 42 for the user to take hot water. In the case where the water outlet end of the heating member 3 is communicated with the water storage member 1, the water storage member 1, the cold water tank 2 and the heating member 3 can be sequentially communicated to form a sterilization loop, so as to facilitate high-temperature sterilization of the water storage member 1, the cold water tank 2, as well as the pipelines and valves, improve the use safety of the drinking water device, and further enhance the user experience.

[0058] It should be noted that the present utility model does not make any limitation on the specific form of the water outlet end of the heating member 3 communicating with the water storage member 1 or the second water outlet member 42, as long as the water outlet end of the heating member 3 can be selectively communicated with the second water outlet member 42 or the water storage member 1.

[0061] It should be noted that although the above two embodiments can both achieve the selective communication between the water outlet end of the heating member 3 and the water storage member 1 or the second water outlet member 42, compared with the form of setting the first water outlet valve and the second water outlet valve, the form of setting the second reversing valve 6 can simplify the pipeline connection and at the same time make it more convenient to switch between the water outlet end of the heating member 3 and the water storage member 1 or the second water outlet member 42.

[0066] Through such a setting, the use of a drainage pump can be saved, the cost of the drinking water device can be reduced, and the user experience can be further improved.

[0067] It should be noted that it is not limited to setting the first end of the drainage pipe 71 to be communicated with the upstream end of the heating member 3. For example, the first end of the drainage pipe 71 can also be set to be communicated with the downstream end of the heating member 3. And so on. Such flexible adjustments and changes 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. Of course, preferably, the first end of the drainage pipe 71 is communicated with the upstream end of the heating member 3.

[0068] Preferably, as Figure 1 shown, the drinking water device of the present utility model further includes a first water pump 23 and a second water pump 531. The first water pump 23 is used to transport the water in the cold water tank 2 to the first water outlet member 41, and the second water pump 531 is used to transport the water in the water storage member 1 or the cold water tank 2 through the heating member 3 to the second water outlet member 42.

It is also convenient to transport the water heated by the heating member 3 to the second water outlet member 42 through the second water pump 531, and then it is convenient to output hot water, further improving the user experience.

[0070] It should be noted that the water in the cold water tank 2 is not limited to being transported to the first water outlet member 41 by the first water pump 23. For example, the water in the cold water tank 2 can also be transported to the first water outlet member 41 by means of gravity, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be included within the protection scope of the present utility model. Of course, preferably, the water in the cold water tank 2 is transported to the first water outlet member 41 by the first water pump 23.

[0071] Specifically, as Figure 1 shown, the cold water tank 2 is connected to the first water outlet member 41 through the cold water outlet pipe 22, and the first water pump 23 is arranged on the cold water outlet pipe 22.

[0072] It should be noted that the water in the water storage member 1 or the cold water tank 2 is not limited to being transported to the second water outlet member 42 through the heating member 3 by the second water pump 531. For example, the water in the water storage member 1 or the cold water tank 2 can also be transported to the second water outlet member 42 through the heating member 3 by means of gravity, and so on.

For example, the second water pump 531 can be arranged at the upstream end of the heating member 3, or the second water pump 531 can also be arranged at the downstream end of the heating member 3, and so on. Such adjustments and changes to the specific installation position of the second water pump 531 do not deviate from the principle and scope of the present utility model and should be included within the protection scope of the present utility model.

[0076] By arranging the exhaust pipe 8, the air pressure in the water storage member 1 can be balanced, which helps the water in the water storage member 1 to be transported into the cold water tank 2 or the heating member 3. At the same time, compared with the form of arranging an exhaust port on the water storage member 1, connecting the other end of the exhaust pipe 8 to the second water outlet member 42 can prevent external bacteria from entering the water storage member 1 through the exhaust port.

[0077] It should be noted that it is not limited to connecting the other end of the exhaust pipe 8 to the second water outlet member 42. For example, the other end of the exhaust pipe 8 can also be connected to the first water outlet member 41, and so on. Such adjustments and changes to the specific connection method of the exhaust pipe 8 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention. Of course, preferably, the other end of the exhaust pipe 8 is connected to the second water outlet member 42.

[0081] Specifically, please refer to Figure 2 , Figure 2 which is the connection structure schematic Figure 2 of the drinking water device of the present invention, and the water flow diagram when the cold water tank is in normal use is shown therein.

[0082] As Figure 2 shown, the water inlet end of the heating member 3 is connected to the water storage member 1, and the water outlet end of the heating member 3 is connected to the second water outlet member 42.

[0083] When the drinking water device is in the cold water outlet mode, the first water pump 23 is turned on, and the first water pump 23 transports the cold water in the cold water tank 2 to the first water outlet member 41 for the user to take cold water.

[0084] When the drinking water device is in the hot water outlet mode, the second water pump 531 is turned on, and the water in the water storage member 1 can be transported to the heating member 3, and after being heated by the heating member 3, it flows out from the second water outlet member 42 for the user to take hot water.

[0085] Situation 2: The cold water tank is not used for a long time

[0086] Specifically, please refer to Figure 3 , Figure 3 which is the connection structure schematic Figure 3 of the drinking water device of the present invention, and the water flow diagram when the cold water tank is not used for a long time is shown therein.

[0087] Switch the water inlet end of the heating member 3 to communicate with the cold water tank 2. When the user takes hot water, turn on the second water pump 531, and the water in the cold water tank 2 can be transported into the heating member 3. After being heated by the heating member 3, it flows out from the second water outlet member 42 for the user to take hot water, avoiding the deterioration of the water in the cold water tank 2 due to long-term non-use.

[0088] Situation 3: When the drinking water device is in the sterilization mode

[0089] For details, please refer to Figure 4 , Figure 4 which is a schematic diagram of the connection structure of the drinking water device of the present utility model Figure 4 , and the water flow diagram of the drinking water device when performing the sterilization mode is shown therein.

[0090] As Figure 4 shown, switch the water inlet end of the heating member 3 to communicate with the cold water tank 2, and switch the water outlet end of the heating member 3 to communicate with the water storage member 1. The water storage member 1, the cold water tank 2, and the heating member 3 are sequentially connected to form a sterilization loop. The water in the cold water tank 2 flows into the heating member 3 and is heated by the heating member 3, and then is transported into the water storage member 1 for circulating sterilization, so as to sterilize the water storage member 1, the cold water tank 2, the heating member 3, as well as the pipelines and valves. After the sterilization is completed, open the drain valve 72, and the sterilization water in the sterilization loop is discharged through the drain pipe 71 to the drain port of the drinking water device to complete the sterilization.

[0091] It should be noted that although the present utility model takes the pipeline machine as an example to introduce the drinking water device of the present utility model, however, this is not restrictive. The drinking water device of the present utility model is equally applicable to any other possible forms, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0092] So far, the technical solution of the present utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
