Description

Technical Field

[0001] This utility model specifically relates to 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 level to be too high. As a result, some depressurized water will flow out through the air vent valve, causing water loss. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a water dispenser with an added breathing water tank to receive water and steam overflowing from the heating tank, thus avoiding water loss, and with greater freedom in the position of the water tap.

[0005] The purpose of this utility model is achieved as follows: 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 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 valve is installed on the first water outlet pipe. The dispenser is characterized by further including a breathing water tank and a throttling device. 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 inlet and outlet is higher than the horizontal height of the overflow port. The two ends of the throttling device are respectively connected to the overflow port and the inlet and outlet. The electronic control module is electrically connected to the heating tank and the water inlet solenoid valve. When the heating tank is working, the electronic control module controls the inlet solenoid valve to close, and the water in the heating tank expands due to heat. This causes the excess water in the heating tank to overflow into the breathing water tank through the throttling device. At the same time, the steam generated during heating also rises to the breathing water tank through the throttling device 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, 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, and the water in the breathing water tank flows back to the heating tank through the throttling device.

[0006] This water dispenser features a breathing water tank and a throttling device. The throttling device connects the heating tank and the breathing water tank, allowing the expanded water from the heating tank to overflow into the breathing water tank during heating, reducing water volume and heat loss. Simultaneously, the steam generated during heating rises through the throttling device 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 outlet and conforming to ergonomic design principles, thus satisfying diverse design requirements and user needs.

[0007] The objective of this utility model can also be achieved by the following technical measures: Specifically, the throttling element is a throttling valve, which has a first water passage chamber, a second water passage chamber, and a throttling orifice 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 ports. This allows the interference fit inside the heating tank to slowly flow into the breathing water tank after passing through the first water passage chamber, the throttling orifice, and the second water passage chamber during the heating process. Similarly, the process of the breathing water tank returning to the heating tank is the reverse of the above process.

[0008] Specifically, the throttling device is a capillary tube, which has a small-diameter water flow channel inside; the capillary tube can also achieve the purpose of this patent very well, and the capillary tube is easy to obtain.

[0009] 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 in sequence through the throttling device 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.

[0010] Specifically, it further includes a first water level probe, which is installed inside the heating tank or the breathing water 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.

[0011] 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 flow the external tap water and the tap water in the purified water tank to the heating tank, which can better realize the stable hot water operation of the hot water valve. Furthermore, the high water level probe in the purified water tank also serves as the basis for whether the 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.

[0012] Furthermore, 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 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, thus preventing the water in the breathing water tank from overflowing.

[0013] 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, causing the electronic control module to control the water inlet solenoid valve to open the water inlet.

[0014] 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 water in the heating tank from flowing back to the water pump.

[0015] 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.

[0016] The beneficial effects of this utility model are as follows: (1) This water dispenser, by adding a breathing water tank and a throttling device, can realize the connection between the heating tank and the breathing water tank. When the heating tank is heating, the overflow water that expands due to heat overflows into the breathing water tank through the throttling device, reducing water volume and heat loss. At the same time, the steam generated during heating also rises to the breathing water tank through the throttling device and is discharged. This 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 allows for 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.

[0017] (2) During the heating process of the heating tank, the interference level of the heating tank that is heated and expanded slowly flows into the breathing water tank after passing through the first water passage, the throttle hole and the second water passage; similarly, the process of the breathing water tank flowing back to the heating tank is the opposite of the above process.

[0018] (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.

The electronic control module 2 is electrically connected to the heating tank 1 and the water inlet solenoid valve 31 respectively. When the heating tank 1 is heating, the electronic control module 2 controls the inlet solenoid valve 31 to close, and the water in the heating tank 1 expands due to heat, causing the excess water in the heating tank 1 to overflow into the breathing water tank 5 through the throttling device.

When water is needed, the water valve 41 is opened, and the electronic control module 2 controls the inlet solenoid valve 31 to open, allowing external tap water to enter the heating tank 1, and the hot water in the heating tank 1 flows out from the tap.

[0035] Preferably, the first water level probe 10 is located at the top of the interior of the heating tank 1. When the power is turned on for the first time 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.
