Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to a water dispenser with a breathing water tank. 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 air vent valve, causing water volume and heat energy loss. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology and provide a water dispenser with a breathing water tank that can collect water and steam overflowing from the heating tank, thereby reducing water and heat loss and allowing for greater freedom in the position of the water tap.

[0005] The purpose of this utility model is achieved as follows: A water dispenser with a breathing water tank includes a heating tank and an electronic control module. One end of the heating tank is connected to a water inlet pipe and a water inlet solenoid valve is installed on the water inlet pipe. The upper part of the heating tank is connected to a first water outlet pipe and a water inlet valve is installed on the first water outlet pipe. The dispenser is characterized by further including a breathing water tank and a control valve. The upper part of the heating tank is provided with an overflow port. The breathing water tank is provided with an inlet and an outlet. The horizontal height of the overflow port is lower than the horizontal height of the inlet and outlet. The two ends of the control valve are respectively connected to the overflow port and the inlet and outlet. The electronic control module is electrically connected to the heating tank, the water inlet solenoid valve and the control valve. When the heating tank is in operation, the electronic control module controls the inlet solenoid valve to close and the control valve to open. The water in the heating tank expands due to heat, causing excess water in the heating tank to overflow into the breathing water tank through the control valve. At the same time, the steam generated during heating also rises to the breathing water tank through the control valve and is discharged. When water is needed, the hot water valve is opened, and the electronic control module controls the inlet solenoid valve to open and the control valve to close, allowing hot water in the heating tank to flow out from the hot water valve. When the hot water valve is closed, the electronic control module controls the inlet solenoid valve to close and the control valve to open, allowing some water in the breathing water tank to flow back into the heating tank through the control valve.

[0006] This water dispenser with a breathing water tank features a control valve. When the heating tank is heating, the expanded water overflows into the breathing water tank through the control valve, reducing water volume and heat loss. Simultaneously, the steam generated during heating rises to the breathing water tank through the control valve and is discharged, 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 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. This satisfies the diverse aesthetic designs of water dispensers and meets various user needs.

[0007] The objective of this utility model can also be achieved by the following technical measures: Specifically, the control valve is a normally open solenoid valve; solenoid valves are easy to implement and can achieve automated control.

[0008] Specifically, it further includes a first water level probe, which is installed inside the breathing water tank or the heating tank and is electrically connected to the electronic control module. The first water level probe can be used as the detection basis for whether the heating tank stops water intake when water is being introduced. That is, when the first water level probe detects water, it can send a signal to the electronic control module, and then the electronic control module controls the relevant components to stop working and introduce water, thereby realizing automated water intake operation.

[0009] Specifically, it further includes a second water level probe, which is electrically connected to the electronic control module. The first and second water level probes are respectively suspended on the top wall of the inner cavity of the breathing water tank, and the lowest point of the first water level probe is lower than the lowest point of the second water level probe. The second water level probe can serve as a high water level warning for the breathing water tank. That is, when the second water level probe detects water, it can send a signal to the electronic control module to remind the user of the water level in the breathing water tank at this time.

[0010] Specifically, the horizontal plane where the lowest point of the first water level probe is located in the breathing water tank and the horizontal plane where the lowest point of the second water level probe is located form an effective volume W1. The effective volume W1 is used to receive the water flowing in when the hot water tank is overloaded. The effective volume W1 is greater than 4% of the total volume of the hot water tank's inner cavity, so that the breathing water tank can fully receive the hot water (overloaded water) that overflows due to thermal expansion.

[0011] 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.

[0012] 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 purified water tank can pre-store a certain amount of external tap water to facilitate replenishment of the heating tank at any time. The water pump can stably and continuously pump external tap water and tap water in the purified water tank into the heating tank, which can effectively 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 flowing into 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.

[0013] 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.

[0014] Furthermore, the water purification tank is also equipped with a low water level probe, which is electrically connected to the electronic control module. The low water level probe can serve as a feedback basis for water shortage in the water purification tank. That is, when the low water level probe cannot detect water, it can send a signal to the electronic control module, which will then control the water inlet solenoid valve to open the water inlet.

[0015] Specifically, the water outlet of the water tank is located below the low water level probe; so that when the low water level probe cannot detect water, it can send a signal to the electronic control module, causing the electronic control module to control the water pump to stop working, thus avoiding the situation of the water pump running dry.

[0016] 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.

[0017] Specifically, the breathing water tank is located above the heating tank and the clean water tank, which facilitates the return of hot water in the breathing water tank to the heating tank or the clean water tank.

[0018] Specifically, it further includes a second water outlet pipe, which includes a boiling water outlet section, a heat exchange section, and a warm water outlet section connected in sequence. One end of the boiling water outlet section is connected to the upper part of the heating tank, and one end of the warm water outlet section is equipped with a connected warm water valve and a warm water tap. The heat exchange section passes through the inner cavity of the water guide pipe so that the water flowing through the water guide pipe absorbs the heat of the heat exchange section. On the one hand, this cools the boiling water after heat exchange in the heat exchange section into warm water, and finally discharges it through the warm water tap. On the other hand, the heat exchange section plays a certain role in preheating the water in the water guide pipe, which is beneficial to the subsequent heating work of the heating tank.

[0019] Furthermore, a temperature regulating valve is provided between the boiling water outlet section and the warm water outlet section. The temperature regulating valve is electrically connected to the electronic control module. The electronic control module can control the opening angle of the temperature regulating valve, so that different amounts of boiling water and the warm water after heat exchange are mixed, thus achieving better temperature adjustment of the warm water.

[0020] Furthermore, one end of the water valve is also connected to a water tap, which is located above the heating tank, the breathing water tank, and the purified water tank; so that the water tap can be set at a higher position to meet the purpose of this patent.

[0021] Specifically, the warm water tap is located above the heating tank, the breathing water tank, and the purified water tank, so that the warm water tap can be set at a higher position to meet the purpose of this patent.

[0022] The beneficial effects of this utility model are as follows: (1) This water dispenser with a breathing water tank, by adding a breathing water tank and a control valve, allows the overflow water that expands due to heat to flow into the breathing water tank through the control valve when the heating tank is working, reducing water volume and heat loss. At the same time, the steam generated during heating also rises to the breathing water tank through the control 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, satisfying the diversity of water dispenser appearance design and more user needs.

[0023] (2) The first water level probe can be used as the basis for detecting whether the heating tank stops water intake when water is being introduced. That is, when the first water level probe detects water, it can send a signal to the electronic control module, and then the electronic control module controls the relevant components to stop working and introduce water, so as to realize the automated water intake operation.

[0024] (3) The water tank can store a certain amount of external tap water so that it can replenish the heating tank at any time; the water pump can stably and continuously flow the external tap water and the tap water in the water tank to the heating tank, which can better realize the stable hot water operation of the water valve; in addition, the high water level probe in the water tank can also serve as the basis for whether the external tap water stops entering the water tank, that is: when the high water level probe detects water, it can send a signal to the electronic control module, so that the electronic control module controls the water inlet solenoid valve to close.
