Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a drinking water device. Background Art

[0002] Drinking water equipment is usually equipped with a water tank, a heating device and a heat exchange device. The heating device is used to heat the cold water in the water tank into hot water and then send it to the heat exchange device. When the user needs to drink warm water, the hot water can be cooled down by heat exchange in the heat exchange device for the user to drink.

[0003] In the prior art, the coolant used for exchanging heat with hot water in the heat exchange device is circulated, and the repeated absorption of heat by the coolant will cause the heat exchange efficiency of the heat exchange device to become lower and lower. Summary of the invention

[0004] The present application provides a drinking water device, which can solve the problem of low heat exchange efficiency of the heat exchange device in the prior art.

[0005] An embodiment of the present application provides a drinking water device, including a main body, which is provided with a water outlet; a water tank, which is installed on the main body; a heating device, which is installed inside the main body; and a heat exchange device, which is installed outside the main body, wherein the heat exchange device has a cooling chamber and a hot water chamber that can perform heat exchange; the two ends of the cooling chamber are respectively connected to the water tank and the heating device, so that the cold water in the water tank can flow into the cooling chamber, and after heat exchange with the hot water in the hot water chamber, flow to the heating device for heating; the two ends of the hot water chamber are respectively connected to the heating device and the water outlet, so that the hot water heated by the heating device can flow to the water outlet after heat exchange with the cold water in the cooling chamber.

[0006] In the above scheme, the cold water used for heat exchange in the cooling cavity is flowing, and the cold water in the cooling cavity can flow to the heating device after absorbing the heat of the hot water in the hot water cavity, and the water tank can continuously replenish cold water to the cooling cavity, so that the heat exchange device can realize live water heat exchange, which can improve the heat exchange efficiency of the heat exchange device. Moreover, since the heat exchange device is installed on the outside of the main body and the heating device is installed on the inside of the main body, the heat exchange device will not be affected by the high temperature of the heating device, which is conducive to the heat dissipation of the heat exchange device, thereby further improving the heat exchange efficiency of the heat exchange device. In addition, the cold water in the cooling cavity flows to the heating device for heating after absorbing the heat of the hot water in the hot water cavity, which can improve the heating efficiency of the heating device, shorten the waiting time of the user, and reduce the energy consumption of the drinking water equipment. The boiling water heated by the heating device can flow into the hot water cavity again, and after heat exchange with the cold water in the cooling cavity, it is cooled to the temperature required by the user and then discharged through the water outlet, that is, the water that the user drinks is boiled and then cooled, and the sterilization effect is better, which can improve the safety of drinking water, thereby improving the user's experience.

[0007] In a possible design, the drinking water equipment also includes a water tank, which is installed on the main body; the water tank is connected to the water tank and the cooling chamber respectively, and the cold water in the water tank can flow to the cooling chamber through the water tank; or, the water tank is connected to the cooling chamber and the heating device respectively, and the cold water in the cooling chamber can flow to the heating device through the water tank after heat exchange.

[0008] In the above scheme, when the water storage tank is connected to the water tank and the cooling chamber respectively, the water storage tank can store some cold water when the heat exchange device is not working. The water in the water storage tank can flow into the cooling chamber when the heat exchange device is working, shortening the flow path of the cold water, facilitating the subsequent rapid heat exchange of the heat exchange device, and is beneficial to improving the heat exchange efficiency of the heat exchange device. When the water storage tank is connected to the cooling chamber and the heating device respectively, the water storage tank can store some warm water after absorbing heat when the heating device is not working, and then be sent to the heating device for heating when the user needs drinking water, which is beneficial to improving the heating efficiency of the heating device. Moreover, the water after heat exchange in the cooling chamber flows into the water storage tank for storage, which can avoid the water after heat exchange from being retained in the cooling chamber and affecting the heat dissipation effect of the heat exchange device.

[0009] In a possible design, the water tank is detachably connected to the main body.

[0010] In the above solution, the user can directly remove the water tank to drink the water in the water tank, and the detachable structure also makes it convenient for the user to clean the water tank.

[0012] In the above scheme, the water storage tank and the heat exchange device are integrated into an integral structure to reduce the total volume of the two, and it is also beneficial to shorten the length of the connecting pipe between the water storage tank and the heat exchange device, thereby improving the heat exchange efficiency of the heat exchange device. When the heat exchange tube has a tube cavity and the hot water cavity is formed in the tube cavity, it is beneficial to increase the volume of the hot water cavity, thereby improving the single cooling capacity of the heat exchange device. When the inner wall of the heat exchange tube and the outer wall of the water storage tank together form a hot water cavity, the volume occupied by the heat exchange tube in the cooling cavity can be reduced, so that the cooling cavity can accommodate more cold water, which is beneficial to improve the heat exchange efficiency of the heat exchange device.

[0014] In the above scheme, the water storage tank and the heat exchange device can be integrated into an integral structure to reduce the total volume of the two, and it is also beneficial to shorten the length of the connecting pipe between the water storage tank and the heat exchange device, thereby improving the heat exchange efficiency of the heat exchange device. When the heat exchange tube has a tube cavity and the hot water cavity is formed in the tube cavity, it is beneficial to increase the volume of the hot water cavity, thereby improving the single cooling capacity of the heat exchange device. When the inner wall of the heat exchange tube and the inner wall of the water storage tank together form a hot water cavity, the volume occupied by the heat exchange tube in the cooling cavity can be reduced, so that the cooling cavity can accommodate more cold water, which is beneficial to improve the heat exchange efficiency of the heat exchange device.

[0015] In a possible design, the heat exchange tube is spirally wound along the axial direction of the water storage tank.

[0016] In the above scheme, the heat exchange tube is arranged in a spiral coil along the axial direction of the water tank, so that the hot water cavity is distributed in a threaded shape on the side wall of the water tank, thereby extending the path of the hot water cavity. When the hot water flows in the hot water cavity, it can flow around the side wall of the water tank for multiple circles, ensuring that the hot water in the hot water cavity can fully exchange heat with the cold water in the cooling cavity, which is beneficial to improving the heat exchange efficiency of the heat exchange device.

[0017] In a possible design, the side wall of the main body is installed with a first coupling part, a second coupling part, a third coupling part and a fourth coupling part; the side wall of the shell is installed with a first coupling fitting part, a second coupling fitting part, a third coupling fitting part and a fourth coupling fitting part, the first coupling fitting part is plugged and matched with the first coupling part to connect the hot water chamber with the heating device; the second coupling fitting part is plugged and matched with the second coupling part to connect the hot water chamber with the water outlet; when the water storage tank is connected with the water tank and the cooling chamber respectively, the third coupling fitting part is plugged and matched with the third coupling part to connect the water storage tank with the water tank; the fourth coupling fitting part is plugged and matched with the fourth coupling part to connect the cooling chamber with the heating device; or, when the water storage tank is connected with the cooling chamber and the heating device respectively, the third coupling fitting part is plugged and matched with the third coupling part to connect the cooling chamber with the water tank; the fourth coupling fitting part is plugged and matched with the fourth coupling part to connect the water storage tank with the heating device.

[0018] In the above scheme, the first coupling part, the second coupling part, the third coupling part and the fourth coupling part are respectively plugged into and matched with the first coupling mating part, the second coupling mating part, the third coupling mating part and the fourth coupling mating part, which can realize the connectivity of various water channels on the one hand, and realize the detachable installation of the water purification cup assembly and the main body on the other hand.

[0019] In a possible design, the drinking water equipment also includes a first water pump; when the water storage tank is connected to the water tank and the cooling chamber respectively, the first water pump is connected to the cooling chamber and the heating device respectively; or, when the water storage tank is connected to the cooling chamber and the heating device respectively, the first water pump is connected to the water storage tank and the heating device respectively.

[0020] In the above scheme, when the water storage tank is connected to the water tank and the cooling chamber respectively, the first water pump is used to pump the water after absorbing heat in the cooling chamber and send it to the heating device, so as to improve the heating efficiency of the heating device and shorten the waiting time of the user. When the water storage tank is connected to the cooling chamber and the heating device respectively, the first water pump is used to pump the water after absorbing heat stored in the water storage tank and send it to the heating device, so as to improve the heating efficiency of the heating device and shorten the waiting time of the user.

[0021] In a possible design, the drinking water equipment also includes a three-way valve, which includes an inlet valve port, a first water outlet valve port and a second water outlet valve port; the inlet valve port is connected to the heating device, the first water outlet valve port is connected to the water outlet, and the second water outlet valve port is connected to the hot water chamber.

[0022] In the above scheme, when the user needs boiling water, the water inlet valve port can be connected to the first water outlet valve port, so that the boiling water heated by the heating device flows directly to the water outlet, and the flow path of the boiling water is short, which is convenient for the user. When the user needs water at a lower temperature, the water inlet valve port can be connected to the second water outlet valve port, so that the boiling water heated by the heating device can be cooled to the temperature required by the user through the heat exchange device, and then flow out from the water outlet for the user to drink.

[0023] In a possible design, the heating device, the first water pump and the three-way valve are an integrated structure.

[0024] In the above solution, when the heating device, the first water pump and the three-way valve are integrated into one, the total space occupied by the three is smaller, which is conducive to reducing the volume of the main body, thereby realizing the miniaturization of the drinking water equipment.

[0025] In a possible design, the drinking water equipment also includes a second water pump, which includes a water inlet end, a first water outlet end and a second water outlet end; when the water storage tank is respectively connected to the water tank and the cooling chamber, the water inlet end is connected to the cooling chamber, and the first water outlet end and the second water outlet end are respectively connected to the heating device and the water storage tank; or, when the water storage tank is respectively connected to the cooling chamber and the heating device, the water inlet end is connected to the water storage tank, and the first water outlet end and the second water outlet end are respectively connected to the heating device and the cooling chamber.

[0026] In the above scheme, when the outlet end of the water storage tank is connected to the inlet end of the cooling chamber, the second water pump can pump out the water after absorbing heat in the cooling chamber through the water inlet end, and send part of the water into the heating device through the first water outlet end, and send the other part of the water back to the water storage tank through the second water outlet end for recycling. Therefore, in the case where the filtering device cannot make up the clean water, the cold water in the water storage tank can be used to neutralize and cool the warm water drawn out from the cooling chamber to achieve recycling. When the outlet end of the water storage tank is used to communicate with the inlet end of the heating device, the second water pump can pump out the water after absorbing heat stored in the water storage tank through the water inlet end, and send part of the water into the heating device through the first water outlet end, and send the other part of the water back to the cooling chamber through the second water outlet end for recycling.

[0028] In the above scheme, the clean water obtained after filtering and removing impurities can flow to the cooling chamber through the clean water end for use in the heat exchange device to improve the safety of drinking water. The waste water can flow back to the water tank through the waste water end to be filtered and used next time, which can realize the recycling of waste water and achieve the effect of water saving.

[0029] In a possible design, the drinking water equipment further includes a regulating valve, which is respectively connected to the wastewater end and the water tank, and is used to control the flow rate of the liquid flowing from the wastewater end to the water tank.

[0030] In the above scheme, by controlling the opening of the regulating valve, the flow rate of the liquid flowing from the wastewater end to the water tank can be controlled, so that the ratio between the clean water output and the wastewater output of the filtering device can be adjusted to reduce unnecessary wastewater treatment and reduce resource waste. Moreover, by controlling the opening of the regulating valve, the filtering device can be adapted to different water quality conditions to ensure that the filtering device has a good filtering effect for water of different water qualities.

[0032] In the above scheme, the heating condition of the heating device can be determined by setting the first temperature sensor and the second temperature sensor, so as to timely adjust the working state of the heating device. The heat exchange condition of the heat exchange device can be determined by setting the third temperature sensor, so as to timely adjust the working state of the heat exchange device.

[0033] In a possible design, a display component is disposed outside the main body, and the display component is electrically connected or signal-connected to at least one of the first temperature sensor, the second temperature sensor, and the third temperature sensor.

[0034] In the above solution, the display component can display the detection results of the corresponding temperature sensor, so that the user can observe the heating condition of the heating device and the heat exchange condition of the heat exchange device.

[0035] In a possible design, the water tank is detachably connected to the outside of the main body.

[0036] In the above solution, when the user fills the water tank with water, he can remove the water tank to operate without moving the entire drinking water device, which is more convenient to use. Moreover, the water tank is set as a detachable structure, which is also convenient for the user to clean the inside of the water tank and reduce the risk of bacteria breeding inside the water tank.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0094] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0095] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0096] The present application embodiment provides a drinking water device, such as Figures 1 to 3 As shown, the drinking water equipment includes a main body 1, a water tank 2, a heating device 3 and a heat exchange device 4, and the main body 1 is provided with a water outlet 11. The water tank 2 is used to hold unheated cold water, the heating device 3 is installed inside the main body 1, and the heat exchange device 4 is installed outside the main body 1. The heat exchange device 4 has a cooling chamber 41 and a hot water chamber 42 capable of heat exchange, and the two ends of the cooling chamber 41 are respectively connected with the water tank 2 and the heating device 3, so that the cold water in the water tank 2 can flow into the cooling chamber 41, and after heat exchange with the hot water in the hot water chamber 42, flow to the heating device 3 for heating. The two ends of the hot water chamber 42 are respectively connected with the heating device 3 and the water outlet 11, so that the hot water heated by the heating device 3 can flow to the water outlet 11 after heat exchange with the cold water in the cooling chamber 41.

[0097] It should be noted that the cold water and hot water described in this embodiment refer to water with a relatively low temperature that has not been heated by the heating device 3, and water with a relatively high temperature that has been heated by the heating device 3, and the water temperature is not limited to a certain temperature range.

[0098] In this embodiment, the cold water used for heat exchange in the cooling chamber 41 is flowing, and the cold water in the cooling chamber 41 can flow to the heating device 3 after absorbing the heat of the hot water in the hot water chamber 42, and the water tank 2 can continuously replenish cold water to the cooling chamber 41, so that the heat exchange device 4 can realize live water heat exchange, which can improve the heat exchange efficiency of the heat exchange device 4. Moreover, since the heat exchange device 4 is installed outside the main body 1 and the heating device 3 is installed inside the main body 1, the heat exchange device 4 will not be affected by the high temperature of the heating device 3, which is conducive to the heat dissipation of the heat exchange device 4, thereby further improving the heat exchange efficiency of the heat exchange device 4. In addition, in this embodiment, the cold water in the cooling chamber 41 absorbs the heat of the hot water in the hot water chamber 42 and then flows to the heating device 3 for heating, which can improve the heating efficiency of the heating device 3, shorten the water output response speed of the drinking water device, thereby shortening the waiting time of the user, and reducing the energy consumption of the drinking water device. The boiling water heated by the heating device 4 can then flow into the hot water chamber 42, and after heat exchange with the cold water in the cooling chamber 41, it is cooled to the temperature required by the user and then discharged through the water outlet 11. That is, the water the user drinks is boiled and then cooled, which has a better sterilization effect, can improve the safety of drinking water, and thus enhance the user experience.

[0099] The heat exchange device 4 can cool the hot water to different water temperatures to meet the different usage requirements of users. Figure 3 As shown, a third temperature sensor 45 may be provided at the outlet end of the hot water chamber 42, and the third temperature sensor 45 is used to detect the water temperature of the drinking water flowing from the hot water chamber 42 to the water outlet 11, that is, the third temperature sensor 45 is used to detect the outlet water temperature of the drinking water device. The drinking water device further includes an electrical control component, which may be provided in the main body 1, and the electrical control component includes at least a control board and a power supply, and the power supply is used to supply power to the control board and various electrical components of the drinking water device. The control board can be electrically connected or signal-connected to the third temperature sensor 45 to receive data detected by the third temperature sensor 45. The control board can also be electrically connected or signal-connected to the water pump that supplies water to the cooling chamber 41 and / or the water pump that draws water from the cooling chamber 41, and can also be electrically connected or signal-connected to the water pump that supplies water to the hot water chamber 42 and / or the water pump that draws water from the hot water chamber 42, so that the working state of each water pump can be controlled according to the difference between the detection data of the third temperature sensor 45 and the drinking water temperature preset by the user, and then the heat exchange efficiency of the heat exchange device 4 can be controlled to change the water outlet temperature of the water outlet 11, so that the water outlet temperature of the drinking water equipment can be accurately controlled, which can improve the user's experience.

[0100] In this embodiment, the water tank 2 can be installed inside or outside the main body 1, and the water tank 2 can be fixedly connected to the main body 1 or detachably connected to the main body 1. Figure 4As shown, this embodiment is introduced by taking the water tank 2 detachably installed on the outside of the main body 1 as an example. Specifically, a mounting base 17 may be provided on the outside of the main body 1, and the water tank 2 may be detachably connected to the mounting base 17 by means of snap-on or plug-in connection. When the user fills the water tank 2 with water, the water tank 2 may be removed for operation without having to move the entire drinking water device, which is more convenient to use. Moreover, the water tank 2 is arranged in a detachable structure, which is also convenient for the user to clean the inside of the water tank 2 and reduce the risk of bacteria breeding inside the water tank 2. Furthermore, a guide groove 21 may be provided on the side wall of one of the water tank 2 and the main body 1, and a guide portion may be provided on the side wall of the other, and the guide groove 21 may cooperate with the guide portion to improve the installation efficiency and convenience of the water tank 2.

[0101] In addition, if Figure 1 and Figure 4 As shown, the drinking water device further includes a drain box 18 detachably connected to the main body 1, and the drain box 18 can be installed directly below the water outlet 11 by plugging or snapping. When the user receives water, the cup can be placed on the drain box 18, and the drain box 18 can collect water to prevent the water outlet 11 from leaking or the cup from overflowing and flowing onto the table and the ground.

[0102] In a specific embodiment, Figure 2 and Figure 3 As shown, the drinking water equipment also includes a filter device 9, which includes a raw water end 91, a clean water end 92 and a waste water end 93. The raw water end 91 is connected to the water tank 2, the clean water end 92 is connected to the cooling chamber 41, and the waste water end 93 is connected to the water tank 2. A filter element is arranged inside the filter device 9. The cold water flowing into the filter device 9 from the raw water end 91 can produce clean water and waste water through the filtering action of the filter element. The clean water obtained after the impurities are removed by the filter element can flow to the cooling chamber 41 through the clean water end 92 for use by the heat exchange device 4 to improve the safety of drinking water. The waste water can flow back to the water tank 2 through the waste water end 93 to be filtered and used next time, so that the waste water can be recycled and the effect of water saving can be achieved.

[0103] In this embodiment, the drinking water device further includes a third water pump 95, the two ends of which are respectively connected to the water tank 2 and the raw water end 91, so as to pump the water in the water tank 2 and send it to the filter device 9 to improve the water delivery efficiency. The third water pump 95 can be a booster pump, which can boost the pressure of the water delivered to the filter device 9, thereby improving the filtration efficiency of the filter device 9, shortening the filtration time, and thus improving the water output response speed of the drinking water device.

[0104] The drinking water device may further include a fourth temperature sensor 22, which may be installed in the connecting pipe between the water tank 2 and the third water pump 95 or at the outlet of the water tank 2, and is used to detect the water temperature flowing from the water tank 2 to the filter device 9. Specifically, the fourth temperature sensor 22 and the third water pump 95 are respectively electrically connected or signal-connected to the control board, and the control board can receive the detection data transmitted by the fourth temperature sensor 22. When the water temperature detected by the fourth temperature sensor 22 is too high (exceeding the applicable water temperature range of the filter element), the control board can control the third water pump 95 to shut down, so as to prevent the hot water with too high temperature from flowing into the filter device 9 and damaging the filter element.

[0105] Furthermore, if Figure 3 As shown, the drinking water equipment also includes a regulating valve 94, which is connected to the wastewater end 93 and the inlet end of the water tank 2 respectively. By controlling the opening of the regulating valve 94, the flow rate of the liquid flowing from the wastewater end 93 to the water tank 2 can be controlled, so that the ratio between the clean water output and the wastewater output of the filter device 9 can be adjusted to reduce unnecessary wastewater treatment and reduce resource waste. Moreover, by controlling the opening of the regulating valve 94, the filter device 9 can adapt to different water quality conditions to ensure that the filter device 9 has a good filtering effect for water of different water qualities.

[0106] like Figure 2 and Figure 3 As shown, the drinking water device further includes a water tank 5, which can be installed inside the main body 1 or outside the main body 1. This embodiment is described by taking the example of the water tank 5 being installed outside the main body 1.

[0107] In a specific embodiment, the inlet end of the water storage tank 5 can be directly connected to the outlet end of the water tank 2, or it can be connected to the clean water end 91 of the filter device 9. This embodiment is described by taking the inlet end of the water storage tank 5 being connected to the clean water end 91 as an example: the outlet end of the water storage tank 5 is connected to the inlet end of the cooling chamber 41, and the water in the water tank 2 flows into the water storage tank 5 after being filtered by the filter device 9. The water storage tank 5 can store some clean water filtered by the filter device 9 when the heat exchange device 4 is not working. The cold clean water in the water storage tank 5 can flow into the cooling chamber 41 when the heat exchange device 4 is working, shortening the flow path of the cold water, facilitating the subsequent heat exchange device 4 to quickly exchange heat without waiting for the filter device 9 to filter, which is conducive to improving the heat exchange efficiency of the heat exchange device 4. The water storage tank 5 can be fixedly connected to the main body 1, or it can be detachably connected to the main body 1. When the water storage tank 5 is detachably connected to the main body 1, the user can directly remove the water storage tank 5 and pour out the filtered cold water for drinking. And the detachable structure is also convenient for users to clean the water storage tank 5.

[0108] Alternatively, in another specific embodiment, the inlet end of the water storage tank 5 is connected to the outlet end of the cooling chamber 41, and the outlet end of the water storage tank 5 is connected to the inlet end of the heating device 3. The water in the water tank 2 is filtered by the filter device 9 and flows into the cooling chamber 41 for heat exchange. The water that completes the heat exchange in the cooling chamber 41 flows into the water storage tank 5 again, that is, the water storage tank 5 can store some warm water after absorbing heat when the heating device 3 is not working, and then it is sent to the heating device 3 for heating when the user needs to drink water, which is conducive to improving the heating efficiency of the heating device 3. Moreover, the water after heat exchange in the cooling chamber 41 flows into the water storage tank 5 for storage, which can avoid the water after heat exchange from being retained in the cooling chamber 41 to affect the heat dissipation effect of the heat exchange device 4. Similarly, the water storage tank 5 can be fixedly connected to the main body 1, or it can be detachably connected to the main body 1. When the water storage tank 5 is detachably connected to the main body 1, the user can directly remove the water storage tank 5 to pour out the warm water after absorbing heat for drinking. And the detachable structure also makes it convenient for users to clean the water storage tank 5.

[0109] In the above two embodiments, the drinking water device further includes a second water pump 8, which includes a water inlet end 81, a first water outlet end 82 and a second water outlet end 83. When the outlet end of the water storage tank 5 is connected to the inlet end of the cooling chamber 41, as shown in FIG. Figure 5 As shown, the water inlet 81 is connected to the outlet of the cooling chamber 41, and the first water outlet 82 and the second water outlet 83 are respectively connected to the inlet of the heating device 3 and the inlet of the water storage tank 5. The second water pump 8 can pump out the water after absorbing heat in the cooling chamber 41 through the water inlet 81, and send part of the water into the heating device 3 through the first water outlet 82, and send the other part of the water back to the water storage tank 5 through the second water outlet 83 for recycling. Therefore, in the case that the filter device 9 cannot replenish the clean water, the cold water in the water storage tank 5 can be used to neutralize and cool the warm water drawn out of the cooling chamber 41 to achieve recycling. A one-way valve 51 can also be set in the connecting pipeline between the second water outlet 83 and the water storage tank 5 to prevent the water in the water storage tank 5 from flowing back into the second water pump 8.

[0110] When the outlet end of the water storage tank 5 is used to communicate with the inlet end of the heating device 3, the water inlet end 81 is communicated with the outlet end of the water storage tank 5, and the first water outlet end 82 and the second water outlet end 83 are respectively communicated with the inlet end of the heating device 3 and the inlet end of the cooling chamber 41. The second water pump 8 can pump out the water stored in the water storage tank 5 after absorbing heat through the water inlet end 81, and send part of the water into the heating device 3 through the first water outlet end 82, and send the other part of the water back to the cooling chamber 41 through the second water outlet end 83 for recycling. Therefore, in the case that the filter device 9 cannot replenish the clean water, the warm water stored in the water storage tank 5 can be sent back to the cooling chamber 41 for recycling. A one-way valve 51 can also be set in the connecting pipeline between the second water outlet end 83 and the cooling chamber 41 to prevent the water in the cooling chamber 41 from flowing back into the second water pump 8.

[0111] In the above two embodiments, the drinking water equipment further includes a first water pump 6, which is installed inside the main body 1. When the outlet end of the water storage tank 5 is connected to the inlet end of the cooling chamber 41, the first water pump 6 is respectively connected to the outlet end of the cooling chamber 41 and the inlet end of the heating device 3, and is used to pump the water after absorbing heat in the cooling chamber 41 and send it to the heating device 3, so as to improve the heating efficiency of the heating device 3 and shorten the waiting time of the user. Similarly, when the outlet end of the water storage tank 5 is used to be connected to the inlet end of the heating device 3, the first water pump 6 is respectively connected to the outlet end of the water storage tank 5 and the inlet end of the heating device 3, and is used to pump the water after absorbing heat stored in the water storage tank 5 and send it to the heating device 3, so as to improve the heating efficiency of the heating device 2 and shorten the waiting time of the user. Among them, if the drinking water equipment is provided with the first water pump 6 and the second water pump 8 at the same time, in the above two embodiments, the inlet end of the first water pump 6 is connected to the first water outlet 82.

[0112] Furthermore, the drinking water device may also be provided with a flow meter, which is installed in the connecting pipe between the first water pump 6 and the heating device 3, and is used to detect the water inlet rate of the heating device 3. The flow meter and the first water pump 6 may be electrically connected or signal-connected to the control board respectively, and the control board may control the working state of the first water pump 6 according to the detection data of the flow meter, thereby controlling the heating efficiency of the heating device 3.

[0113] In a specific embodiment, Figure 3 As shown, the drinking water device also includes a three-way valve 7, which is installed inside the main body 1. The three-way valve 7 includes an inlet valve port 71, a first outlet valve port 72, and a second outlet valve port 73. The inlet valve port 71 is connected to the heating device 3, the first outlet valve port 72 is connected to the water outlet 11, and the second outlet valve port 73 is connected to the hot water chamber 42. When the user needs boiling water, the inlet valve port 71 can be controlled to be connected to the first outlet valve port 72, so that the boiling water heated by the heating device 3 flows directly to the water outlet 11, and the flow path of the boiling water is short, which is convenient for the user to use. When the user needs water at a lower temperature, the inlet valve port 71 can be controlled to be connected to the second outlet valve port 73, so that the boiling water heated by the heating device 3 can be cooled to the temperature required by the user through the heat exchange device 4, and then flow out from the water outlet 11 for the user to drink. Specifically, the three-way valve 7 can be electrically connected or signal-connected to the control board, and the control board controls the water inlet valve port 71 to communicate with the first water outlet valve port 72 or the second water outlet valve port 73 .

[0114] In addition, the three-way valve 7 can be an ordinary three-way valve or a three-way water mixing valve. When the three-way valve 7 is a three-way water mixing valve, the water flow rate of the first water outlet valve port 72 and the second water outlet valve port 73 can be adjusted, so that when the water inlet valve port 71 is connected to the first water outlet valve port 72, the water volume flowing from the three-way valve 7 to the water outlet 11 can be adjusted, and when the water inlet valve port 71 is connected to the second water outlet valve port 73, the water volume flowing from the three-way valve 7 to the heat exchange device 4 can be adjusted.

[0115] In this embodiment, the heating device 3, the first water pump 6 and the three-way valve 7 can be an integrated structure. When the heating device 3, the first water pump 6 and the three-way valve 7 are integrated into one, the total space occupied by the three is smaller, which is conducive to reducing the volume of the main body 1, thereby realizing the miniaturization of the drinking water equipment.

[0116] In a specific embodiment, the drinking water device further includes a first temperature sensor 31 and a second temperature sensor 32. The first temperature sensor 31 is installed at the inlet end of the heating device 3 to collect the temperature of the liquid flowing into the heating device 3; the second temperature sensor 32 is installed at the outlet end of the heating device 3 to collect the temperature of the liquid heated by the heating device 3. The heating state of the heating device 3 can be detected by setting the first temperature sensor 31 and the second temperature sensor 32. The heating device 3, the first temperature sensor 31 and the second temperature sensor 32 can be electrically connected or signal-connected to the control board respectively. The control board can judge the heating state of the heating device 3 according to the data detected by the first temperature sensor 31 and the second temperature sensor 32, and adjust the working state of the heating device 3 according to the judgment result to ensure that the heating device 3 can boil the water, and can turn off the heating device 3 in time after the heating is completed, so as to achieve the effect of energy saving.

[0117] Furthermore, if Figure 1As shown, a display component 16 is provided on the outside of the main body 1, and the display component 16 is electrically connected or signal-connected to at least one of the first temperature sensor 31, the second temperature sensor 32, and the third temperature sensor 45, so that the display component 16 can display the detection results of the corresponding temperature sensor, which is convenient for the user to observe the heating condition of the heating device 3 and the heat exchange condition of the heat exchange device 4. Specifically, the display component 16 may include a display screen and a signal conversion module, the signal input end of the display screen is electrically connected or signal-connected to the signal output end of the signal conversion module, and the signal input end of the signal conversion module is used to be electrically connected or signal-connected to at least one of the first temperature sensor 31, the second temperature sensor 32, and the third temperature sensor 45. The analog signal of the temperature sensor can be converted into a digital signal after being processed by the signal conversion module, and then the digital signal is displayed on the display screen. Specifically, when the first temperature sensor 31 is connected to the display component 16, the user can observe the temperature of the inlet end of the heating device 3 through the display screen; when the second temperature sensor 32 is connected to the display component 16, the user can observe the temperature of the outlet end of the heating device 3 through the display screen; when the third temperature sensor 45 is connected to the display component 16, the user can observe the temperature of the outlet end of the hot water chamber 42 through the display screen.

[0118] In addition, the display screen can also have an operating function. The display screen can be electrically or signal-connected to the control panel. When the user operates the operating buttons on the display screen, the control panel can control the working status of various electrical components of the drinking water equipment according to the user's operation.

[0119] In this embodiment, the water storage tank 5 and the heat exchange device 4 can be integrated into an integral structure to reduce the total volume of the two, and also help to shorten the length of the connecting pipe between the water storage tank 5 and the heat exchange device 4, thereby helping to improve the heat exchange efficiency of the heat exchange device 4. Figure 1 and Figure 2 As shown, the water storage tank 5 and the heat exchange device 4 together form a water purification cup assembly 10. The water purification cup assembly 10 is detachably connected to the outside of the main body 1, and a cup tray is provided on the side wall of the main body 1, and the water purification cup assembly 10 can be placed on the cup tray 19.

[0120] This embodiment provides two specific implementations for the structure of the water purification cup assembly 10, such as Figure 2 and Figure 6As shown, in the first embodiment, the heat exchange device 4 includes a shell 43 and a heat exchange tube 44, the shell 43 is sleeved on the water tank 5, and the cooling chamber 41 is formed between the outer wall of the water tank 5 and the inner wall of the shell 43, that is, the water tank 5 is nested in the heat exchange device 4. The heat exchange tube 44 is installed in the cooling chamber 41, and the heat exchange tube 44 can have a tube cavity, and the hot water chamber 42 is formed in the tube cavity. This structure is conducive to increasing the volume of the hot water chamber 42, thereby increasing the single cooling capacity of the heat exchange device 4. The heat exchange tube 44 can be a round tube or a square tube, or a pipeline with other cross-sectional shapes, which is not limited in this embodiment. The heat exchange tube 44 can be fixed to the outer wall of the water tank 5 to shorten the connecting pipeline between the water tank 5 and the cooling chamber 41. Furthermore, the heat exchange tube 44 can be arranged to be spirally coiled along the axial Z direction of the water tank 5, so that the hot water chamber 42 is distributed in a threaded shape on the outer wall of the water tank 5, thereby extending the path of the hot water chamber 42. When the hot water flows in the hot water chamber 42, it can flow around the outer wall of the water tank 5 for multiple circles, ensuring that the hot water in the hot water chamber 42 can fully exchange heat with the cold water in the cooling chamber 41, which is beneficial to improving the heat exchange efficiency of the heat exchange device 4.

[0121] like Figure 7 As shown, the heat exchange tube 44 can be an open structure, which can be fixedly connected to the outer wall of the water storage tank 5, so that the inner wall of the heat exchange tube 44 and the outer wall of the water storage tank 5 can enclose the hot water cavity 42 together. This structure can reduce the volume occupied by the heat exchange tube 44 in the cooling cavity 41, so that the cooling cavity 41 can accommodate more cold water, which is beneficial to improve the heat exchange efficiency of the heat exchange device 4. Similarly, the open heat exchange tube 44 can also be arranged to be spirally wound along the axial direction Z of the water storage tank 5 to extend the path of the hot water cavity 42.

[0122] A handle may also be provided on the outer shell 43 to facilitate the user to pick up and move the water purification cup assembly 10. The water purification cup assembly 10 may also include a cup cover 101, which can be snapped onto the top of the outer shell 43 to prevent dust.

[0123] In this embodiment, the side wall of the main body 1 is installed with a first coupling part 12, a second coupling part 13, a third coupling part 14 and a fourth coupling part 15, and the side wall of the shell 43 is correspondingly installed with a first coupling matching part 431, a second coupling matching part 432, a third coupling matching part 431 and a fourth coupling matching part 434. Among them, the first coupling part 12 is connected to the outlet end of the heating device 3 through the three-way valve 7, the first coupling matching part 431 is connected to the inlet end of the hot water chamber 42, and the first coupling matching part 431 is plugged and matched with the first coupling part 12 to connect the hot water chamber 42 with the heating device 3, so that the boiling water heated by the heating device 3 can flow into the heat exchange device 4 for heat exchange. The second coupling part 13 is connected to the water outlet 11, the second coupling matching part 432 is connected to the outlet end of the hot water chamber 42, and the second coupling matching part 432 is plugged and matched with the second coupling part 13 to connect the hot water chamber 42 with the water outlet 11, so that the water after heat exchange and cooling can flow out from the water outlet 11.

[0124] When the inlet end of the water tank 5 is connected with the water tank 2 through the filtering device 9, the third coupling part 14 is connected with the clean water end 92, the third coupling matching part 433 is connected with the inlet end of the water tank 5, and the third coupling matching part 433 is plugged and matched with the third coupling part 14 to connect the water tank 5 with the filtering device 9, so that the clean water filtered by the filtering device 9 can flow into the water tank 5 for storage; the fourth coupling part 15 is connected with the inlet end of the heating device 3 through the second water pump 6, the fourth coupling matching part 434 is connected with the outlet end of the cooling chamber 41, and the fourth coupling matching part 434 is plugged and matched with the fourth coupling part 15 to connect the cooling chamber 41 with the heating device 3, so that the water after absorbing heat in the cooling chamber 41 can flow into the heating device 3 for heating.

[0125] When the inlet end of the water tank 5 is connected with the outlet end of the cooling chamber 41, the third coupling part 14 is connected with the clean water end 92, the third coupling matching part 433 is connected with the inlet of the cooling chamber 41, and the third coupling matching part 433 is plugged and matched with the third coupling part 14, so that the cooling chamber 41 can be connected with the water tank 2 through the filtering device 9, and the clean water filtered by the filtering device 9 can flow into the cooling chamber 41 for heat exchange; it is connected with the inlet end of the heating device 3 through the second water pump 6, the fourth coupling matching part 434 is connected with the outlet end of the water tank 5, and the fourth coupling matching part 434 is plugged and matched with the fourth coupling part 15, so as to connect the water tank 5 with the heating device 3, so that the water after absorbing heat in the water tank 5 can flow into the heating device 3 for heating.

[0126] In this embodiment, the first coupling part 12, the second coupling part 13, the third coupling part 14 and the fourth coupling part 15 are respectively plugged and matched with the first coupling matching part 431, the second coupling matching part 432, the third coupling matching part 431 and the fourth coupling matching part 434, which can realize the communication of various waterways on the one hand, and can also realize the detachable installation of the water purification cup assembly 10 and the main body 1 on the other hand. In this embodiment, the first coupling part 12, the second coupling part 13, the third coupling part 14 and the fourth coupling part 15 can be an integrated structure or a split structure; the first coupling matching part 431, the second coupling matching part 432, the third coupling matching part 431 and the fourth coupling matching part 434 can be an integrated structure or a split structure.

[0127] It should be noted that Figure 1 and Figure 6 The arrangement order of the positions of the first coupling portion 12, the second coupling portion 13, the third coupling portion 14 and the fourth coupling portion 15, and the arrangement order of the positions of the first coupling fitting portion 431, the second coupling fitting portion 432, the third coupling fitting portion 431 and the fourth coupling fitting portion 434 are only for reference and may also be arranged in other orders.

[0128] In another embodiment, the heat exchange device includes a panel and a heat exchange tube 44. The panel is fixedly installed in the water tank 5. The panel and the inner wall of the water tank 5 together form a cooling chamber 41, that is, the heat exchange device 4 is nested in the water tank 5. The heat exchange tube 44 is installed in the cooling chamber 41. The heat exchange tube 44 has a tube cavity, and the hot water chamber 42 is formed in the tube cavity. This structure is conducive to increasing the volume of the hot water chamber 42, thereby increasing the single cooling capacity of the heat exchange device 4. The heat exchange tube 44 can be a round tube or a square tube, or a pipeline with other cross-sectional shapes, which is not limited in this embodiment. The heat exchange tube 44 can be fixed to the inner wall of the water tank 5 to shorten the connecting pipeline between the water tank 5 and the cooling chamber 41. Furthermore, the heat exchange tube 44 can be arranged to be spirally coiled along the axial Z direction of the water tank 5, so that the hot water chamber 42 is distributed in a threaded shape on the inner wall of the water tank 5, thereby extending the path of the hot water chamber 42. When the hot water flows in the hot water chamber 42, it can flow around the inner wall of the water tank 5 for multiple circles, ensuring that the hot water in the hot water chamber 42 can fully exchange heat with the cold water in the cooling chamber 41, which is beneficial to improving the heat exchange efficiency of the heat exchange device 4.

[0129] Alternatively, the heat exchange tube 44 may be an open structure, and the heat exchange tube 44 may be fixedly connected to the inner wall of the water storage tank 5, so that the inner wall of the heat exchange tube 44 and the inner wall of the water storage tank 5 together form a hot water cavity 42. This structure can reduce the volume occupied by the heat exchange tube 44 in the cooling cavity 41, so that the cooling cavity 41 can accommodate more cold water, which is beneficial to improving the heat exchange efficiency of the heat exchange device 4. Similarly, the open heat exchange tube 44 can also be arranged to be spirally wound along the axial direction Z of the water storage tank 5 to extend the path of the hot water cavity 42.

[0130] In this embodiment, the outer wall of the water tank 5 can be provided with a handle to facilitate the user to pick up and move the water purification cup assembly 10. The water purification cup assembly 10 can also include a cup cover 101, which can be buckled on the top of the water tank 5 to play a dust-proof role.

[0131] Similarly, in this embodiment, the side wall of the main body 1 is installed with the first coupling part 12, the second coupling part 13, the third coupling part 14 and the fourth coupling part 15, and the side wall of the water storage tank 5 is correspondingly installed with the first coupling matching part 431, the second coupling matching part 432, the third coupling matching part 431 and the fourth coupling matching part 434. The functions and effects of each coupling part and each coupling matching part are the same as those in the previous embodiment, and will not be repeated here.

[0132] In the above two embodiments, the material of the heat exchange tube 44 can be aluminum, iron, gold, silver, copper, lead, tin, steel, stainless steel or other alloy materials, or metal-clad materials (such as aluminum-clad stainless steel, aluminum-clad copper, etc.), or other materials with a thermal conductivity higher than 10W / mK, which is not limited in this embodiment.

[0133] The wall thickness of the heat exchange tube 44 can be 0.1mm to 1mm, specifically 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm, or other values ​​within the above range, which are not limited in this embodiment. If the wall thickness of the heat exchange tube 44 is less than 0.1mm, the strength of the heat exchange tube 44 will be insufficient, and the heat exchange tube 44 will be easily deformed or even damaged when the water pressure of the hot water is high; if the wall thickness of the heat exchange tube 44 is greater than 1mm, the heat exchange between the hot water cavity 42 and the cooling cavity 41 will be affected, resulting in a decrease in the heat exchange efficiency of the heat exchange device 4, and an excessively thick wall thickness will also cause the heat exchange tube 44 to be too large, occupying too much space in the cooling cavity 41. Therefore, when the wall thickness of the heat exchange tube 44 is 0.1 mm to 1 mm, it can not only improve the heat exchange efficiency of the heat exchange device 4 , but also improve the structural strength of the heat exchange tube 44 , and appropriately reduce the volume of the heat exchange tube 44 .

[0134] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
