Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a drinking water device. Background Technology

[0002] Water supply equipment typically includes a heating device and a heat exchange device. When a user needs warm water, the heat exchange device can cool the hot water heated by the heating device before supplying it to the user.

[0003] Existing heat exchangers typically employ a dual-tube structure, where hot water flows in an inner tube and cooling water flows in an outer tube. The cooling water exchanges heat with the hot water through the inner tube wall. However, due to the small cross-sectional area of ​​the pipes, the cooling effect of the cooling water is limited, resulting in low heat exchange efficiency for the dual-tube structure and negatively impacting the user experience. Utility Model Content

[0004] This application provides a drinking water device that can solve the problem of low heat exchange efficiency in existing drinking water devices.

[0005] This application provides a drinking water device, including: a water outlet; a heating device; a cold water tank for storing cooling water; and a heat exchange pipeline installed in the cold water tank. The heat exchange pipeline includes a heat exchange inlet and a heat exchange outlet, the heat exchange inlet being connected to the heating device, and the heat exchange outlet being connected to the water outlet.

[0006] In the above scheme, hot water heated by the heating device enters the heat exchange pipeline through the heat exchange inlet. As the hot water flows through the heat exchange pipeline, it exchanges heat with the cooling water in the cold water tank, cooling it down. The cooled water then flows from the heat exchange outlet to the water outlet for the user to drink. In this embodiment, the heat exchange pipeline is located inside the cold water tank, allowing it to be directly immersed in the cooling water. This increases the contact area between the heat exchange pipeline and the cooling water, improving the heat exchange efficiency of the drinking water equipment and achieving a rapid cooling effect. Furthermore, the efficient heat exchange structure allows the drinking water equipment to provide more warm water in a shorter time, reducing user waiting time and increasing the flow rate of warm water from the outlet, thereby improving the user experience. On the other hand, by placing the heat exchange pipeline inside the cold water tank, this embodiment of the application achieves an integrated effect of the heat exchange device and the cold water tank. The overall volume is equivalent to the size of a cold water tank. Compared with the drinking water equipment in the prior art that combines a cold water tank with a dual-pipe heat exchange structure, the structure of the drinking water equipment provided by this embodiment of the application can save internal space, which is conducive to reducing the size of the drinking water equipment and realizing miniaturization. Moreover, since this embodiment of the application eliminates the cold water pipeline, there is no need to set up a cold water pump for sending cooling water from the cold water tank into the cold water pipeline, which helps to simplify the structure of the drinking water equipment and reduce the overall cost of the drinking water equipment.

[0007] In one possible design, the heat exchange pipeline includes straight pipe sections and bends, with multiple straight pipe sections spaced apart along the length of the cold water tank, and the multiple straight pipe sections connected end to end in sequence through the bends.

[0008] In the above scheme, the heat exchange piping can form a tortuous pipe structure inside the cold water tank, ensuring that longer heat exchange piping can be installed within the limited space inside the cold water tank. This extends the flow path of hot water in the heat exchange piping, thereby improving the heat exchange efficiency. Multiple straight pipe sections are distributed at intervals along the length of the cold water tank to ensure a reasonable spacing between adjacent straight pipe sections. This facilitates heat dissipation from the heat exchange piping and prevents localized overheating of the cooling water, thus promoting sufficient heat exchange between the cooling water and the hot water in the heat exchange piping.

[0009] In one possible design, the diameter of the heat exchange pipeline is 4mm to 8mm; and / or, the length of the heat exchange pipeline is 1000mm to 2000mm.

[0010] In the above scheme, when the diameter of the heat exchange pipeline is 4mm~8mm, it ensures that the water flow rate in the heat exchange pipeline remains within a reasonable range. This improves the heat exchange efficiency between the heat exchange pipeline and the cooling water, reduces the risk of complete blockage of the heat exchange pipeline, and extends its service life. This helps shorten the user's waiting time for drinking water and improves the user experience. When the length of the heat exchange pipeline is 1000mm~2000mm, it ensures sufficient heat exchange between the hot water and cooling water while appropriately reducing the production cost of the drinking water equipment. Therefore, when the diameter of the heat exchange pipeline is 4mm~8mm and the length is 1000mm~2000mm, the production cost of the drinking water equipment can be reduced while improving its heat exchange efficiency.

[0011] In one possible design, the drinking water device further includes a hot water pipe, a water outlet pipe, and a solenoid valve. The inlet and outlet of the water outlet pipe are connected to the solenoid valve and the water outlet, respectively. The inlet and outlet of the hot water pipe are connected to the heating device and the solenoid valve, respectively. The heat exchange inlet and the heat exchange outlet are connected to the solenoid valve, respectively. The solenoid valve is used to control the connection between the outlet of the hot water pipe and the heat exchange inlet, and the connection between the heat exchange outlet and the inlet of the water outlet pipe, while simultaneously controlling the disconnection between the outlet of the hot water pipe and the inlet of the water outlet pipe. The solenoid valve is also used to control the connection between the outlet of the hot water pipe and the inlet of the water outlet pipe, while simultaneously controlling the disconnection between the outlet of the hot water pipe and the heat exchange inlet, and the disconnection between the heat exchange outlet and the inlet of the water outlet pipe.

[0012] In the above solution, when the user needs hot water, the hot water in the heating device can be controlled by a solenoid valve to flow directly to the outlet, avoiding the hot water from exchanging heat with the cooling water when it flows through the heat exchange pipe, which would cause the hot water temperature to drop.

[0013] In one possible design, the drinking water device includes a main body, with the water outlet and the heating device both disposed on the main body, and the cold water tank detachably connected to the main body; the drinking water device also includes a hot water pipeline disposed on the main body, the inlet of the hot water pipeline communicating with the heating device, and the outlet of the hot water pipeline having a first connecting member to one of the heat exchange inlets and a second connecting member to the other, the first connecting member and the second connecting member being inserted into each other to form a connection between the hot water pipeline and the heat exchange pipeline; and / or, the drinking water device also includes a water outlet pipeline disposed on the main body, the outlet of the water outlet pipeline communicating with the water outlet, and the inlet of the water outlet pipeline having a first connecting member to one of the heat exchange outlets and a second connecting member to the other, the first connecting member and the second connecting member being inserted into each other to form a connection between the water outlet pipeline and the heat exchange pipeline.

[0014] In the above scheme, when the cold water tank is placed inside the main body, the first connecting piece and the second connecting piece are plugged in and connected. At this time, the hot water in the hot water pipe can flow into the heat exchange pipe for heat exchange. Similarly, when the cold water tank is placed inside the main body, the first connecting piece and the second connecting piece are plugged in and connected. At this time, the warm water that has completed heat exchange in the heat exchange pipe can flow to the outlet through the outlet pipe. Setting up the first and second connecting pieces not only allows the heat exchange pipe to be connected to the hot water pipe and the outlet pipe respectively, but also enables the installation of the cold water tank, improving the installation reliability of the cold water tank.

[0015] In one possible design, a sealing ring is provided on the inner wall of the first connecting member and / or the outer wall of the second connecting member; when the first connecting member and the second connecting member are inserted into each other, a sealing fit is formed between the outer wall of the second connecting member and the inner wall of the first connecting member through the sealing ring.

[0016] In the above scheme, setting a sealing ring helps to improve the sealing effect between the first connecting part and the second connecting part, avoid water leakage at the connection between the heat exchange pipe and the hot water pipe and the connection between the heat exchange pipe and the outlet pipe, and reduce the risk of short circuits in the electrical components inside the main body.

[0017] In one possible design, the first connecting member is provided with a first water inlet, and a first one-way valve assembly is provided inside the first connecting member; the second connecting member is provided with a second water inlet, and a second one-way valve assembly is provided inside the second connecting member; when the first connecting member and the second connecting member are plugged into each other, the first one-way valve assembly and the second one-way valve assembly are used to simultaneously open the first water inlet and the second water inlet; when the first connecting member and the second connecting member are disconnected, the first one-way valve assembly and the second one-way valve assembly are used to simultaneously close the first water inlet and the second water inlet.

[0018] In the above solution, by setting the first one-way valve assembly and the second one-way valve assembly, it can be ensured that when the cold water tank is removed from the main body, there will be no leakage in the heat exchange pipeline, hot water pipeline and outlet pipeline.

[0019] In one possible design, the drinking water device includes a main body and a hot water pipe, the hot water pipe being installed on the main body, the inlet of the hot water pipe being connected to the heating device, and the outlet of the hot water pipe being connected to the heat exchange inlet; the main body is provided with a viewing window, the viewing window being positioned corresponding to the hot water pipe, and the hot water pipe being a transparent pipe.

[0020] In the above solution, a communicating vessel structure can be formed between the hot water pipe and the heating device. Users can observe the liquid level in the hot water pipe through the viewing window to determine the liquid level in the heating device, so that users can control the heating status of the heating device in time and avoid the situation where the heating device burns dry without water.

[0021] In one possible design, the cold water tank is equipped with a temperature detection device, which is installed on the side wall of the cold water tank and is used to detect the temperature of the cooling water in the cold water tank.

[0022] In the above solution, the water dispenser can adjust the flow rate of hot water into the heat exchange pipeline according to the detection results of the temperature sensor, thereby ensuring that the water temperature after heat exchange and cooling by the heat exchange device meets the user's needs and achieving precise temperature control of the water dispenser.

[0023] In one possible design, the drinking water device includes a main body, with the water outlet and the heating device both disposed on the main body, and the cold water tank detachably connected to the main body; the main body is provided with a power supply, and the cold water tank is provided with an electrocoupler, which is installed on the side wall of the cold water tank for making the power supply electrically connected to the temperature detection element when the cold water tank is connected to the main body; the heat exchange inlet, the heat exchange outlet, and the electrocoupler are offset from each other in the height direction of the cold water tank.

[0024] The above solution can prevent water from dripping from the heat exchange inlet or outlet onto the electrical coupler during the installation and disassembly of the cold water tank, thus reducing the risk of short circuits.

[0025] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0029] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0033] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0034] This application provides a drinking water device, such as... Figure 1 and Figure 2As shown, the drinking water equipment includes a main body 10, a heating device installed on the main body 10, and a cold water tank 20. The main body 10 is provided with a water outlet communicating with the outside. The heating device is used to store and heat liquid, and the cold water tank 20 is used to store cooling water. The drinking water equipment also includes a heat exchange pipeline 1, which is installed inside the cold water tank 20, combined with... Figure 3 As shown, the heat exchange pipeline 1 includes a heat exchange inlet 11 and a heat exchange outlet 12. The heat exchange inlet 11 is connected to the heating device, and the heat exchange outlet 12 is connected to the water outlet. Hot water heated by the heating device enters the heat exchange pipeline 1 through the heat exchange inlet 11. During the flow of the hot water in the heat exchange pipeline 1, it can exchange heat with the cooling water in the cold water tank 20 to cool down. The cooled water flows from the heat exchange outlet 12 to the water outlet for users to drink.

[0035] In this embodiment, the heat exchange pipe 1 is installed inside the cold water tank 20, allowing it to be directly immersed in the cooling water. This increases the contact area between the heat exchange pipe 1 and the cooling water, improving the heat exchange efficiency of the drinking water equipment and achieving rapid cooling. Furthermore, the efficient heat exchange structure enables the drinking water equipment to provide more warm water in a shorter time, reducing user waiting time and increasing the flow rate of warm water from the outlet, thereby enhancing the user experience.

[0036] On the other hand, by placing the heat exchange pipeline 1 inside the cold water tank 20, this embodiment of the application achieves the integration of the heat exchange device and the cold water tank 20. The overall volume is equivalent to the size of a cold water tank 20. Compared with the drinking water equipment in the prior art that combines a cold water tank with a dual-pipe heat exchange structure, the structure of the drinking water equipment provided by this embodiment of the application can save internal space, which is conducive to reducing the size of the drinking water equipment and realizing miniaturization. Moreover, since the cold water pipeline is eliminated in this embodiment of the application, there is no need to set up a cold water pump for sending cooling water from the cold water tank into the cold water pipeline, which helps to simplify the structure of the drinking water equipment and reduce the total cost of the drinking water equipment.

[0037] In this embodiment, the highest point of the heat exchange pipeline 1 should be lower than the highest liquid level of the cooling water in the cold water tank 20, so as to ensure that the heat exchange pipeline 1 can be completely submerged in the cooling water, thereby increasing the contact area between the heat exchange pipeline 1 and the cooling water, and thus improving the heat exchange efficiency of the drinking water equipment.

[0038] In one specific implementation, such as Figure 4As shown, the heat exchange pipeline 1 includes straight pipe sections 13 and bends 14. Multiple straight pipe sections 13 are connected end-to-end via bends 14, forming a tortuous pipeline structure within the cold water tank 20. This ensures that a longer heat exchange pipeline 1 can be installed within the limited space of the cold water tank 20, thereby extending the flow path of hot water in the heat exchange pipeline 1 and improving its heat exchange efficiency. The multiple straight pipe sections 13 are spaced apart along the length X of the cold water tank 20 to ensure a reasonable distance between adjacent straight pipe sections 13, facilitating heat dissipation from the heat exchange pipeline 1 and preventing excessively high local temperatures in the cooling water. This promotes sufficient heat exchange between the cooling water and the hot water in the heat exchange pipeline 1.

[0039] Preferably, the straight pipe section 13 and the bent pipe section 14 are an integral structure, and the heat exchange pipe 1 can be made of 304 stainless steel pipe bent into shape.

[0040] In one specific embodiment, the diameter of the heat exchange pipe 1 is 4mm to 8mm, specifically 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm or 8mm, or other values ​​within the above range. This embodiment does not limit this.

[0041] If the diameter of heat exchange pipe 1 is too small (e.g., less than 4mm), the water flow to the outlet will be small, making it inconvenient for users. Furthermore, a small diameter pipe is prone to scale buildup, affecting the lifespan of heat exchange pipe 1. If the diameter of heat exchange pipe 1 is too large (e.g., greater than 8mm), it will occupy too much space in the cold water tank 20, reducing the amount of cooling water it can hold. An excessively large diameter will also prevent the water inside heat exchange pipe 1 from fully exchanging heat with the cooling water, resulting in reduced heat exchange efficiency.

[0042] Therefore, when the diameter of heat exchange pipe 1 is 4mm~8mm, it can ensure that the water flow rate in heat exchange pipe 1 is kept within a reasonable range. This can improve the heat exchange efficiency between heat exchange pipe 1 and cooling water, reduce the risk of heat exchange pipe 1 being completely blocked, and thus extend the service life of heat exchange pipe 1. This will help shorten the user's drinking water waiting time and improve the user experience.

[0043] In one specific embodiment, the length of the heat exchange pipe 1 is 1000mm~2000mm, specifically 1000mm, 1100mm, 1200mm, 1300mm, 1400mm, 1500mm, 1600mm, 1700mm, 1800mm, 1900mm or 2000mm, or other values ​​within the above range. This embodiment does not limit this.

[0044] If the length of heat exchange pipe 1 is too short (e.g., less than 1000 mm), the flow path of hot water in heat exchange pipe 1 will be too short, easily leading to insufficient heat exchange and resulting in the final outlet water temperature being higher than the user's required temperature. If the length of heat exchange pipe 1 is too long (e.g., greater than 2000 mm), heat exchange pipe 1 will occupy too much space in cold water tank 20, resulting in a reduction in the amount of cooling water it can hold, and consequently, a reduction in the effective heat exchange cycles of the cooling water. Moreover, an excessively long heat exchange pipe 1 will also increase the overall cost of the drinking water equipment.

[0045] Therefore, when the length of heat exchange pipeline 1 is 1000mm~2000mm, it can ensure that the hot water and cooling water in heat exchange pipeline 1 can exchange heat fully, and can also appropriately reduce the production cost of drinking water equipment.

[0046] In one specific implementation, such as Figure 5 As shown, the drinking water equipment also includes a hot water pipe 2, a water outlet pipe 3, and a solenoid valve 4. The inlet and outlet of the water outlet pipe 3 are connected to the solenoid valve 4 and the water outlet, respectively. The inlet and outlet of the hot water pipe 2 are connected to the heating device and the solenoid valve 4, respectively. The heat exchange inlet 11 and the heat exchange outlet 12 are connected to the solenoid valve 4. The solenoid valve 4 is used to simultaneously control the connection between the outlet of the hot water pipe 2 and the heat exchange inlet 11, and the heat exchange outlet 12 and the inlet of the water outlet pipe 3, while simultaneously cutting off the connection between the outlet of the hot water pipe 2 and the inlet of the water outlet pipe 3. At this time, the hot water heated by the heating device can enter the heat exchange pipe 1 through the hot water pipe 2 for heat exchange, and finally flow to the water outlet through the water outlet pipe 3 to provide warm drinking water for users. The solenoid valve 4 is also used to control the connection between the outlet of the hot water pipe 2 and the inlet of the outlet pipe 3, while simultaneously controlling the connection between the outlet of the hot water pipe 2 and the heat exchange inlet 11, and the connection between the heat exchange outlet 12 and the inlet of the outlet pipe 3. At this time, the hot water heated by the heating device can flow directly from the hot water pipe 2 to the outlet pipe 3, and then to the outlet, so as to provide hot water for the user to drink.

[0047] By setting up solenoid valve 4, when the user needs hot water, the hot water in the heating device can be controlled to flow directly to the outlet through solenoid valve 4, avoiding the hot water temperature from dropping due to heat exchange with cooling water when it flows through heat exchange pipe 1.

[0048] In this embodiment, the drinking water equipment also includes a water pump 7 installed within the main body 10. The water pump 7 is connected to both the heating device and the inlet of the hot water pipe 2, and is used to pump water from the heating device to the hot water pipe 2. The water pump 7 can be an impeller pump without a self-locking function, so that a communicating vessel structure is formed between the heating device and the hot water pipe 2, that is, the liquid level in the hot water pipe 2 is the same as the liquid level in the heating device. The hot water pipe 2 can be a transparent pipe, and a viewing window 101 corresponding to the position of the hot water pipe 2 can be provided on the main body 10 (e.g., a viewing window 101). Figure 1 As shown in the figure, users can judge the liquid level in the heating device by observing the liquid level in the hot water pipe 2, so that users can control the heating status of the heating device in time and avoid the situation of the heating device burning dry without water.

[0049] Because a communicating vessel structure is formed between the heating device and the hot water pipe 2, when unheated tap water is added to the heating device, the tap water will flow directly into the hot water pipe 2. When users use drinking water equipment to get water, this tap water will flow to the outlet, posing a certain drinking water health problem. This embodiment can avoid the above problem by setting a solenoid valve 4. Specifically, when unheated tap water is added to the heating device, the solenoid valve 4 can control the outlet of the hot water pipe 2 to disconnect from the heat exchange inlet 11, and control the outlet of the hot water pipe 2 to disconnect from the inlet of the outlet pipe 3, so that a negative pressure state is formed inside the hot water pipe 2, thereby preventing unheated tap water from flowing from the heating device into the hot water pipe 2.

[0050] In one specific embodiment, the cold water tank 20 can be detachably connected to the main body 10, specifically, as shown in... Figure 1 and Figure 2 As shown, the cold water tank 20 can be connected to the main body 10 by pulling it out from the front or side, making it convenient for users to replace the cooling water in the cold water tank 20. Combined with... Figure 6 As shown, one of the outlet and the heat exchange inlet 11 of the hot water pipe 2 is provided with a first connecting member 5, and the other is provided with a second connecting member 6. The first connecting member 5 and the second connecting member 6 are inserted and connected to form a connection between the hot water pipe 2 and the heat exchange pipe 1. Specifically, the first connecting member 5 is located inside the main body 10 and is connected to the outlet of the hot water pipe 2. One end of the second connecting member 6 is located inside the cold water tank 20 and is connected to the heat exchange inlet 11, and the other end extends into the cold water tank 20. When the cold water tank 20 is placed inside the main body 10, the first connecting member 5 and the second connecting member 6 are inserted and connected. At this time, the hot water in the hot water pipe 2 can flow into the heat exchange pipe 1 for heat exchange.

[0051] Similarly, one of the inlet of the outlet pipe 3 and the heat exchange outlet 12 is provided with a first connecting member 5, and the other is provided with a second connecting member 6. The first connecting member 5 and the second connecting member 6 are inserted and matched to make the outlet pipe 3 connected to the heat exchange pipe 1. Specifically, the first connecting member 5 is located inside the main body 10 and is connected to the inlet of the outlet pipe 3. One end of the second connecting member 6 is located inside the cold water tank 20 and is connected to the heat exchange outlet 12, and the other end extends into the cold water tank 20. When the cold water tank 20 is placed inside the main body 10, the first connecting member 5 and the second connecting member 6 are inserted and connected. At this time, the warm water that has completed heat exchange in the heat exchange pipe 1 can flow to the outlet through the outlet pipe 3.

[0052] The first connecting member 5 and the second connecting member 6 not only allow the heat exchange pipe 1 to connect with the hot water pipe 2 and the outlet pipe 3 respectively, but also enable the installation of the cold water tank 20, improving the installation reliability of the cold water tank 20. The following section provides a detailed description of the specific structure of the first connecting member 5 and the second connecting member 6, using the example of the first connecting member 5 at the outlet of the hot water pipe 2, the second connecting member 6 at the heat exchange inlet 11, the first connecting member 5 at the inlet of the outlet pipe 3, and the second connecting member 6 at the heat exchange outlet 12.

[0053] In this embodiment, when the drinking water equipment is equipped with a solenoid valve 4, the solenoid valve 4 is located between the outlet of the hot water pipe 2 and the first connecting member 5, and between the inlet of the water outlet pipe 3 and the first connecting member 5. That is, the solenoid valve 4 is directly connected to the outlet of the hot water pipe 2 and the inlet of the water outlet pipe 3, but it is connected to the heat exchange inlet 11 and the heat exchange outlet 12 through the insertion and cooperation of the first connecting member 5 and the second connecting member 6.

[0054] In one specific implementation, such as Figure 6 As shown, the heat exchange inlet 11 and the second connecting member 6 are sealed together by the sealing member 8. The sealing member 8 can cover the connection between the heat exchange inlet 11 and the second connecting member 6, which can reduce the risk of water leakage at the connection. Similarly, the heat exchange outlet 12 and the second connecting member 6 can also be sealed together by the sealing member 8 to reduce the risk of water leakage at the connection between the two.

[0055] In one specific implementation, such as Figure 6 As shown, when the first connecting member 5 and the second connecting member 6 are inserted together, the second connecting member 6 extends into the interior of the first connecting member 5. A sealing ring 53 is provided on the inner wall of the first connecting member 5 and / or the outer wall of the second connecting member 6. When the first connecting member 5 and the second connecting member 6 are inserted together, a sealing fit is formed between the outer wall of the second connecting member 6 and the inner wall of the first connecting member 5 through the sealing ring 53. This improves the sealing effect between the first connecting member 5 and the second connecting member 6, preventing water leakage at the connection between the heat exchange pipe 1 and the hot water pipe 2, and at the connection between the heat exchange pipe 1 and the outlet water pipe 3, thus reducing the risk of short circuits in the electrical components inside the main body 10.

[0056] Specifically, when the sealing ring 53 is located on the inner wall of the first connecting member 5, a groove can be cut into the inner wall of the first connecting member 5, and the sealing ring 53 can be installed in the groove, which helps to improve the installation stability of the sealing ring 53. When the sealing ring 53 is located on the outer wall of the second connecting member 6, the sealing ring 53 can be directly fitted onto the outer wall of the second connecting member 6, or a groove can be cut into the outer wall of the second connecting member 6, and the sealing ring 53 can be installed in the groove, which helps to improve the installation stability of the sealing ring 53.

[0057] In one specific implementation, such as Figure 6 As shown, the first connecting member 5 is provided with a first water inlet 51, and a first one-way valve assembly 52 is provided inside the first connecting member 5. The second connecting member 6 is provided with a second water inlet 61, and a second one-way valve assembly 62 is provided inside the second connecting member 6. When the first connecting member 5 and the second connecting member 6 are connected, the first one-way valve assembly 52 and the second one-way valve assembly 62 are used to simultaneously open the first water inlet 51 and the second water inlet 61; when the first connecting member 5 and the second connecting member 6 are disconnected, the first one-way valve assembly 52 and the second one-way valve assembly 62 are used to simultaneously close the first water inlet 51 and the second water inlet 61. By setting the first one-way valve assembly 52 and the second one-way valve assembly 62, it can be ensured that when the cold water tank 20 is removed from the main body 10, no water leakage will occur in the heat exchange pipe 1, the hot water pipe 2, and the outlet pipe 3.

[0058] Combination Figure 6 and Figure 7 As shown, the first one-way valve assembly 52 includes a first valve body 521, a first sealing ring 522, and a first return spring 523. The first sealing ring 522 is sleeved on the first valve body 521, and the first return spring 523 is sleeved on the first valve body 521, with its two ends abutting against the edges of the first valve body 521 and the first water inlet 51, respectively. The second one-way valve assembly 62 includes a second valve body 621, a second sealing ring 622, and a second return spring 623. The second sealing ring 622 is sleeved on the second valve body 621, and the second return spring 623 is sleeved on the second valve body 621, with its two ends abutting against the edges of the second valve body 621 and the second water inlet 61, respectively. When the first connecting member 5 and the second connecting member 6 are inserted and engaged, at least a portion of the second valve body 621 extends into the first connecting member 5 and presses against the first valve body 521. Under their interaction, the first valve body 521 and the second valve body 621 move inwards respectively, compressing the first return spring 523 and the second return spring 623 respectively. During this process, the first sealing ring 522 and the second sealing ring 622 move with the first valve body 521 and the second valve body 621 respectively to synchronously open the first water inlet 51 and the second water inlet 61. When the first connecting member 5 and the second connecting member 6 are disassembled, the first valve body 521 and the second valve body 621 can reset under the restoring force of the first return spring 523 and the second return spring 623 respectively. At this time, the first sealing ring 522 and the second sealing ring 622 move with the first valve body 521 and the second valve body 621 respectively to synchronously close the first water inlet 51 and the second water inlet 61.

[0059] In one specific implementation, such as Figure 4As shown, the cold water tank 20 is equipped with a temperature detection element 201, which is installed on the side wall of the cold water tank 20. The temperature detection element 201 is used to detect the temperature of the cooling water in the cold water tank 20. A control board is installed inside the main body 10. The control board is electrically or signal-connected to the temperature detection element 201 and is used to receive the detection results from the temperature detection element 201. The controller can adjust the flow rate of hot water pump 7 to hot water pipe 2 according to the user-set outlet water temperature and the detection results of the temperature detection element 201, thereby realizing the automatic temperature control function of the drinking water equipment. This ensures that the water temperature after heat exchange and cooling by the heat exchange device meets the user's needs, achieving precise temperature control of the drinking water equipment. When the temperature of the cooling water increases with the increase of the number of heat exchange cycles and the heat exchange time, the controller can adjust the flow rate of hot water according to the real-time detection results of the temperature detection element 201, thereby achieving a constant outlet water temperature and improving the user experience. Furthermore, when the cooling water temperature is too high and cannot complete the heat exchange work, the controller can also prompt the user to replace the cooling water in time by issuing an alarm or by displaying it on the display panel 102 of the main body 10.

[0060] In this embodiment, a power supply is installed inside the main body 10, and an electrical coupler 202 is installed in the cold water tank 20. The electrical coupler 202 is installed on the side wall of the cold water tank 20 and electrically connected to the temperature detection element 201. When the cold water tank 20 is installed and connected to the main body 10, the electrical coupler 202 is used to establish an electrical connection between the power supply and the temperature detection element 201, using the power supply to power the temperature detection element 201. At the same time, it also ensures that the temperature detection element 201 can form a signal connection or electrical connection with the controller, so that the controller can receive the detection results of the temperature detection element 201.

[0061] Specifically, the heat exchange inlet 11, heat exchange outlet 12 and the electric coupler 202 are offset in the height direction Z of the cold water tank 20. This can prevent water in the heat exchange pipeline 1 from dripping from the heat exchange inlet 11 or heat exchange outlet 12 onto the electric coupler 202 when the cold water tank 20 is installed and disassembled, thus reducing the risk of short circuit.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
