Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to an improved structure for a water dispenser. Background Technology

[0002] Existing water dispensers or water boilers, such as the applicant's previous Chinese utility model patent CN 220917171U, entitled "Cool Boiled Water Dispenser," with an authorization announcement date of May 10, 2024, involve hot water flowing out under natural water pressure when the tap is turned on. However, in this type of water dispenser, the heating tank must be located at the top of the dispenser, and the tap must be located at the bottom of the heating tank. In other words, the tap cannot be placed at the top of the dispenser, which limits the appearance design of the dispenser and hinders the user experience.

[0003] In some existing water dispensers, the heating water tank is located at the bottom and the hot water tap is located at the top. External tap water enters the heating water tank through its own water pressure or a water pump, is heated, and then flows to the hot water tap at the top through the outlet pipe. However, during the heating process, the hot water in the heating water tank expands, causing the water volume to become too full. As a result, some depressurized water flows out through the vent valve, causing water loss and heat loss. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an improved water dispenser structure by adding a breathing water tank to receive water and steam overflowing from the heating tank, thereby reducing water and heat loss, and allowing for greater freedom in the placement of the water valve.

[0005] The purpose of this utility model is achieved as follows: An improved structure for a water dispenser includes a heating tank and an electronic control module. One end of the heating tank is connected to a water inlet pipe with an inlet solenoid valve. The upper part of the heating tank is connected to a first water outlet pipe with an opening valve. The feature is that it also includes a breathing water tank and a float valve. A first water level probe is provided at the upper part of the interior of the heating tank. An overflow port is provided at the upper part of the heating tank. The breathing water tank has inlet and outlet ports. The horizontal height of the overflow port is lower than that of the inlet and outlet ports. The two ends of the float valve are connected to the overflow port and the inlet and outlet ports, respectively. The electronic control module is electrically connected to the heating tank, the inlet solenoid valve, and the first water level probe, respectively. When the heating tank is in operation, the electronic control module controls the inlet solenoid valve to close, while the float valve remains open. The water in the heating tank expands due to heat, causing excess water to overflow into the breathing water tank through the float valve. Simultaneously, the steam generated during heating also rises through the float valve to the breathing water tank for discharge. When water is needed, the hot water valve is opened, and the electronic control module controls the inlet solenoid valve to open, while the float valve remains closed, allowing hot water from the heating tank to flow out from the tap. When the hot water valve is closed, the electronic control module controls the inlet solenoid valve to close, while the float valve remains open, allowing water in the breathing water tank to flow back into the heating tank through the float valve.

[0006] This water dispenser features an improved structure with the addition of a breathing water tank and a float valve. When the heating tank is heating, the expanded water overflows into the breathing water tank through the float valve, reducing water volume and heat loss. Simultaneously, the steam generated during heating also rises through the float valve to the breathing water tank for discharge, effectively preventing the heating tank from becoming pressurized. Furthermore, when dispensing hot water, external tap water enters the heating tank, and the hot water from the heating tank is discharged through the hot water valve on the first outlet pipe. This design allows the hot water valve on the first outlet pipe to be located at the top of the water dispenser, providing greater flexibility in the placement of the hot water dispenser and conforming to ergonomic design principles, satisfying diverse design preferences and user needs. During this process, the hot water from the heating tank pushes the float valve to close internally, preventing hot water from flowing into the breathing water tank.

[0007] The objective of this utility model can also be achieved by the following technical measures: Specifically, the float valve is provided with a first water passage chamber, a second water passage chamber, and an intermediate water passage connecting the first and second water passage chambers. The first water passage chamber is connected to the overflow port, and the second water passage chamber is connected to the inlet and outlet. A movable floating element is provided in the first water passage chamber, and a first water passage gap exists between the outer periphery of the floating element and the inner wall of the first water passage chamber. The floating element can move under the action of water flow with a certain water pressure and close the intermediate water passage. So that during the heating process of the heating tank, the interference fit of the heating tank due to heat expansion slowly flows through the first water passage chamber, the first water passage gap, the intermediate water passage, and the second water passage chamber and flows into the breathing water tank. When hot water is dispensed, after the external tap water with a certain water pressure flows into the heating tank, the hot water flowing out of the heating tank has a certain pressure. When the hot water with a certain pressure flows through the float valve, it will push the internal floating element to move and close the intermediate water passage, thereby preventing hot water from flowing into the breathing water tank.

[0008] Specifically, the float valve includes an upper valve body and a lower valve body connected to each other. The upper valve body has a second water passage chamber and a middle water passage, and the lower valve body has a first water passage chamber. The lower end of the floating member is placed on the first water passage chamber, and the upper part of the floating member extends into the middle water passage. A second water passage gap exists between the outer periphery of the upper part of the floating member and the inner wall of the middle water passage. On the one hand, the middle water passage cooperates with the upper part of the floating member to guide the subsequent movement of the floating member, so that the floating member can stably close the middle water passage. On the other hand, the second water passage gap prevents the floating member from closing the middle water passage in the initial state, allowing the interference water in the heating tank to pass through and flow into the breathing water tank. Furthermore, the upper valve body provides a mounting carrier for the second water passage chamber and the middle water passage, and the lower valve body provides a mounting carrier for the first water passage chamber, which facilitates the overall manufacturing of the float valve.

[0009] Furthermore, a sealing ring is fitted around the upper outer periphery of the floating component near the central water inlet, so that the floating component can effectively seal the central water inlet.

[0010] The cross-section of the intermediate water inlet and the upper cross-section of the floating component are both narrow at the top and wide at the bottom. This shape of the intermediate water inlet and the floating component facilitates the upper part of the floating component to extend into the intermediate water inlet and improves the stability of the floating component when it closes the intermediate water inlet.

[0011] Specifically, the float valve is provided with a first water passage chamber, a second water passage chamber, and an intermediate water passage chamber. The upper outlet of the intermediate water passage chamber is connected to the second water passage chamber, and the lower outlet of the intermediate water passage chamber is connected to the first water passage chamber. The first water passage chamber is connected to the overflow port, and the second water passage chamber is connected to the inlet and outlet. A drainage groove connected to the lower outlet is opened at the lower part of the intermediate water passage chamber. A movable float is provided in the intermediate water passage chamber, and the lower end of the float is placed on the lower outlet of the intermediate water passage chamber. The float can move upward under the action of water flow with a certain water pressure and close the intermediate water passage chamber. The upper outlet of the intermediate water passage is used to allow the heating tank to expand under heat during operation. The pressure of the water in the heating tank is then released through the first water passage, the lower outlet of the intermediate water passage, the drain trough, the intermediate water passage, and the second water passage before flowing into the breathing water tank. When hot water is dispensed, external tap water with a certain pressure flows into the heating tank, giving the hot water flowing out of the heating tank a certain pressure. When the hot water with a certain pressure flows through the float valve, it pushes the float ball inside to move upward and seal the intermediate water passage, thereby preventing hot water from flowing into the breathing water tank.

[0012] Furthermore, the upper end of the breathing water tank is also provided with an exhaust port; so that the steam generated during the operation of the heating tank can be discharged sequentially through the control valve and the exhaust port on the breathing water tank, thereby enabling the heating tank to communicate with the outside atmosphere and preventing the heating tank from being pressurized.

[0013] Specifically, the water inlet pipe is equipped with a purified water tank and a water pump. The two ends of the water pump are connected to the outlets of the heating tank and the purified water tank, respectively. The water inlet of the purified water tank is connected to the water inlet solenoid valve. A high water level probe is installed inside the purified water tank. The electronic control module is electrically connected to the high water level probe and the water pump. The water pump can stably and continuously pump external tap water and tap water in the purified water tank into the heating tank to achieve stable hot water output from the hot water valve. Furthermore, the high water level probe in the purified water tank can serve as the basis for whether external tap water has stopped entering the purified water tank. That is, when the high water level probe detects water, it can send a signal to the electronic control module, causing the electronic control module to control the water inlet solenoid valve to close.

[0014] Specifically, a breathing water tank interference pipe is provided between the upper part of the purified water tank and the upper part of the breathing water tank; this facilitates the return of some hot water to the purified water tank through the breathing water tank interference pipe when the water level in the breathing water tank is too high, preventing the hot water in the breathing water tank from overflowing and preventing the hot water in the breathing water tank from being discharged through the exhaust port, thus effectively reducing the loss of water and heat.

[0015] Furthermore, a water pipe is connected between the water pump and the heating tank, and a check valve is installed on the water pipe to prevent hot water in the heating tank from flowing back to the water pump.

[0016] The beneficial effects of this utility model are as follows: (1) This water dispenser has an improved structure. By adding a breathing water tank and a float valve, the overflow water that expands due to heat when the heating tank is working overflows into the breathing water tank through the float valve, reducing water volume and heat loss. At the same time, the steam generated during heating also rises to the breathing water tank through the float valve and is discharged, which effectively ensures that the heating tank is not pressurized. Furthermore, when hot water is dispensed, external tap water enters the heating tank, and then the hot water from the heating tank is discharged through the hot water valve of the first water outlet pipe. This setting allows the hot water valve on the first water outlet pipe to be set on the top of the water dispenser, which provides greater freedom in setting the location of the hot water outlet on the water dispenser and conforms to ergonomic design, meeting the diversity of water dispenser appearance design and more user needs. At the same time, during this process, the hot water from the heating tank will push the float valve to close when it passes through the float valve, preventing hot water from flowing into the breathing water tank through the float valve.

[0017] (2) During the heating process of the heating tank, the interference level of the heating tank expands slowly through the first water passage, the first water passage gap, the intermediate water passage and the second water passage before flowing into the breathing water tank. When hot water is discharged, after the external tap water with a certain water pressure flows into the heating tank, the hot water flowing out of the heating tank has a certain pressure. When the hot water with a certain pressure flows through the float valve, it will push the internal floating parts to interact and close the intermediate water passage, thereby preventing hot water from flowing into the breathing water tank.

[0018] (3) On the one hand, the cooperation between the middle water inlet and the upper part of the floating part plays a certain guiding role in the movement of the subsequent floating part, so that the floating part can stably close the middle water inlet. On the other hand, the second water inlet gap makes it possible for the floating part not to close the middle water inlet in the initial state, so that the interference water in the heating tank can pass through and flow into the breathing water tank. Furthermore, the upper valve body provides a mounting carrier for the second water inlet and the middle water inlet, and the lower valve body provides a mounting carrier for the first water inlet, which facilitates the overall manufacturing of the float valve.

[0027] The present patent will be further described below with reference to the accompanying drawings and embodiments: The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures, and should not be construed as limiting the present patent; In order to better illustrate the embodiments of the present patent, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size; It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0029] Implementation examples, in conjunction with Figures 1 to 6 As shown, an improved structure for a water dispenser includes a heating tank 1 and an electronic control module 2. One end of the heating tank 1 is connected to a water inlet pipe 3, and a water inlet solenoid valve 31 is installed on the water inlet pipe 3. The upper part of the heating tank 1 is connected to a first water outlet pipe 4, and a water inlet valve 41 is installed on the first water outlet pipe 4. The device is characterized by further including a breathing water tank 5 and a float valve 6. A first water level probe 11 is installed at the upper end of the interior of the heating tank 1, and an overflow port 12 is installed at the upper end of the heating tank 1. The breathing water tank 5 has inlet and outlet ports 51. The horizontal height of the overflow port 12 is lower than the horizontal height of the inlet and outlet ports 51. The two ends of the float valve 6 are respectively connected to the overflow port 12 and the inlet and outlet ports 51. The electronic control module 2 is electrically connected to the heating tank 1, the water inlet solenoid valve 31, and the first water level probe 11. More specifically, an electric heating element 13 is installed inside the heating tank 1, and the electronic control module 2 is electrically connected to the electric heating element 13. When heating tank 1 is in operation, the electronic control module 2 controls the inlet solenoid valve 31 to close, and the float valve 6 is in the normally open state. The water in heating tank 1 expands due to heat, causing excess water in heating tank 1 to overflow into the breathing water tank 5 through the float valve 6. At the same time, the steam generated during heating also rises through the float valve 6 to the breathing water tank 5 and is discharged. When water is needed, the water valve 41 is opened, the electronic control module 2 controls the inlet solenoid valve 31 to open, and the float valve 6 is in the closed state. External water enters into heating tank 1, and hot water in heating tank 1 flows out from the water valve 41. When the water valve 41 is closed, the electronic control module 2 controls the inlet solenoid valve 31 to close, and the float valve 6 is in the normally open state. The water in the breathing water tank 5 flows back to heating tank 1 through the float valve 6.

[0030] When the power is first applied and water is introduced, the electronic control module 2 controls the water inlet solenoid valve 31 to open, and external tap water flows into the heating tank 1 through the water inlet solenoid valve 31. When the first water level probe 11 detects water, the first water level probe 11 can transmit a signal to the electronic control module 2, so that the electronic control module 2 controls the water inlet solenoid valve 31 to close. During this process, if water flows through the float valve 6, the float valve 6 will be closed, so that water cannot flow into the breathing water tank 5.

[0031] As a specific solution, the float valve 6 is provided with a first water passage chamber 61, a second water passage chamber 62, and an intermediate water passage port 63 connecting the first water passage chamber 61 and the second water passage chamber 62. The first water passage chamber 61 is connected to the overflow port 12, and the second water passage chamber 62 is connected to the inlet and outlet ports 51. The first water passage chamber 61 is provided with a movable floating member 64, and there is a first water passage gap 100 between the outer periphery of the floating member 64 and the inner wall of the first water passage chamber 61. The floating member 64 can move under the action of water flow with a certain water pressure and close the intermediate water passage port 63.

[0032] The working principle of the float valve 6: Because the density of the floating part 64 is greater than that of water, and the heating expansion process of the water in the heating tank 1 is relatively slow, the excess water in the electric heating tank is not enough to push the floating part 64 in the float valve 6 to float up and close the intermediate water inlet 63. Only under the impact of external tap water with a certain pressure (when the inlet solenoid valve 31 is opened) can the floating part 64 in the float valve 6 be pushed up and the intermediate water inlet 63 be closed.

[0033] As a more specific embodiment, the float valve 6 includes an upper valve body 65 and a lower valve body 66 connected to each other. The upper valve body 65 has a second water passage chamber 62 and a middle water passage port 63. The lower valve body 66 has a first water passage chamber 61. The lower end of the floating member 64 is placed on the first water passage chamber 61. The upper part of the floating member 64 extends into the middle water passage port 63, and a second water passage gap 200 exists between the upper outer periphery of the floating member 64 and the inner wall of the middle water passage port 63.

[0034] In this embodiment, a sealing ring 10 is fitted on the upper outer periphery of the floating member 64 near the middle water inlet 63.

[0035] In this embodiment, the cross-section of the intermediate water inlet 63 and the upper cross-section of the floating member 64 are both narrow at the top and wide at the bottom.

[0036] like Figures 4-6 As shown, in another embodiment of the float valve 6, the float valve 6 is provided with a first water passage chamber 61, a second water passage chamber 62 and an intermediate water passage chamber 67. The upper outlet 672 of the intermediate water passage chamber 67 is connected to the second water passage chamber 62, and the lower outlet 673 of the intermediate water passage chamber 67 is connected to the first water passage chamber 61. The first water passage chamber 61 is connected to the overflow port 12, and the second water passage chamber 62 is connected to the inlet and outlet ports 51. The lower part of the intermediate water passage chamber 67 has a drainage groove 671 connected to the lower outlet 673. A movable float 68 is provided in the intermediate water passage chamber 67, and the lower end of the float 68 is placed on the lower outlet 673 of the intermediate water passage chamber 67. The float 68 can move upward under the action of water flow with a certain water pressure and close the upper outlet 672 of the intermediate water passage chamber 67.

[0037] More specifically, the float valve 6 includes an outer shell 20, an intermediate water passage component 30, and a hollow fixing component 40. The outer shell 20 has a first water passage chamber 61, a mounting chamber 69, and a second water passage chamber 62 arranged sequentially from bottom to top. The intermediate water passage component 30 is placed on the mounting chamber 69, and the intermediate water passage component 30 has an intermediate water passage chamber 67. The hollow fixing component 40 is fixed on the first water passage chamber 61, and the upper surface of the hollow fixing component 40 abuts against the lower surface of the intermediate water passage component 30, so that the intermediate water passage component 30 can be stably restricted on the mounting chamber 69 by the hollow fixing component 40. The hollow fixing component 40 is connected to the lower outlet 673 of the intermediate water passage chamber 67 and the first water passage chamber 61.

[0038] More specifically, the intermediate water passage component 30 is made of silicone material, the intermediate water passage cavity 67 is approximately spherical, and the float 68 is made of plastic.

[0039] As a preferred embodiment, the upper end of the breathing water tank 5 is also provided with an exhaust port 52.

[0040] More specifically, the upper end of the breathing water tank 5 is connected to an exhaust pipe 53, one end of which extends into the breathing water tank 5, and the other end of which forms the exhaust port 52.

[0041] As a more specific embodiment, the water inlet pipe 3 is equipped with a clean water tank 32 and a water pump 33. The two ends of the water pump 33 are respectively connected to the outlets of the heating tank 1 and the clean water tank 32. The water inlet solenoid valve 31 is connected to the inlet of the clean water tank 32. A high water level probe 34 is installed inside the clean water tank 32. The electrical control module 2 is electrically connected to the high water level probe 34 and the water pump 33 respectively.

[0042] More specifically, a low water level probe 35 is also provided in the water purification tank 32. The low water level probe 35 is electrically connected to the electronic control module 2. The low water level probe 35 can serve as a feedback basis for water shortage in the water purification tank 32. That is, when the low water level probe 35 cannot detect water, it can transmit a signal to the electronic control module 2, so that the electronic control module 2 controls the water inlet solenoid valve 31 to open the water inlet.

[0043] In this embodiment, a breathing water tank interference pipe 50 is provided between the upper part of the purified water tank 32 and the upper part of the breathing water tank 5.

[0044] Preferably, the inlet / outlet 51 is located at the bottom of the breathing water tank 5.

[0045] Example 2, combined with Figure 7 As shown, this embodiment is similar to Embodiment 1, except that a water pipe 60 is connected between the water pump 33 and the heating tank 1, and a check valve 601 is provided on the water pipe 60.

[0046] Example 3, combined with Figure 8As shown, this embodiment is similar to Embodiment 1, except that it also includes a second water outlet pipe 7. The second water outlet pipe 7 includes a boiling water outlet section 71, a heat exchange section 72, and a warm water outlet section 73 connected in sequence. One end of the boiling water outlet section 71 is connected to the upper part of the heating tank 1. One end of the warm water outlet section 73 is provided with a connected warm water valve 8 and a warm water tap 9. The heat exchange section 72 passes through the inner cavity of the water guide pipe 60 so that the water flowing through the water guide pipe 60 absorbs the heat of the heat exchange section 72. On the one hand, the boiling water after heat exchange in the heat exchange section 72 is cooled down into warm water and finally discharged through the warm water tap 9. On the other hand, the heat exchange section 72 plays a certain preheating role for the water in the water guide pipe 60, which is beneficial to the subsequent heating work of the heating tank 1.

[0047] In this embodiment, both the hot water valve 41 and the warm water valve 8 are solenoid valves, and the electronic control module 2 is electrically connected to the hot water valve 41 and the warm water valve 8 respectively; a temperature regulating valve 74 is also provided between the hot water outlet section 71 and the warm water outlet section 73, and the temperature regulating valve 74 is electrically connected to the electronic control module 2.

[0048] In this embodiment, one end of the water valve 41 is also connected to a water tap 42, which is located above the heating tank 1, the breathing water tank 5, and the clean water tank 32; the warm water tap 9 is located above the heating tank 1, the breathing water tank 5, and the clean water tank 32.

[0049] The embodiments described above are merely examples for clearly illustrating this patent, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this patent, and these all fall within the scope of protection of this patent. Therefore, the scope of protection of this patent should be determined by the appended claims.
