Description

Technical Field

[0001] The invention relates to the field of water dispensers, and more particularly to an embedded water dispenser. Background Art

[0002] Embedded water dispenser is a drinking device that is embedded in the wall or furniture of the kitchen, office or other space to blend in with the surrounding environment. This design is usually intended to save space and enhance aesthetics, and is particularly suitable for modern, compact or customized home and office environments.

[0003] With the development of science and technology, the functions of water dispensers are becoming more and more diverse. They can not only provide hot drinking water but also ice drinking water. The water dispenser includes a water tank and a cold inner tank. The water tank and the cold inner tank are interconnected. The water in the cold inner tank is refrigerated by a compressor to make the drinking water in the cold inner tank reach the level of ice. Then the ice water is pumped from the cold inner tank into a water collecting box through a cold water pump. A water outlet is provided under the water collecting box, and cold water can flow out directly from the water outlet. A heating body is also provided in the water dispenser. One end of the heating body is connected to the water tank through a hot water pump, and the other end of the heating body is connected to the water collecting box. The water in the water tank enters the heating body through the hot water pump for heating, and then enters the water collecting box, and then flows out from the water outlet. By controlling the cold water pump and the hot water pump, it can be controlled whether ice water or hot water flows out from the water outlet.

[0004] Everyone has different expectations about the temperature of water obtained from a water dispenser. After the water dispenser produces hot water, the temperature of the hot water will be transferred to the inner wall of the water collecting box, causing the temperature of the inner wall of the water collecting box to be relatively high. At this time, if someone needs to obtain ice water, especially when the amount obtained is relatively small, the ice water will absorb the heat of the inner wall of the water collecting box when entering the water collecting box, causing the temperature of the ice water to rise, so that the temperature of the water coming out of the outlet cannot meet people's needs.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] An embedded water dispenser, such as Figure 1 and Figure 2 As shown, it includes a body 1, in which a water tank 2, a cold inner tank 3, a heating body 4 and a water collecting box 5 are arranged. A hot water connector 7 and a cold water connector 6 are arranged on the water collecting box 5. The water tank 2 and the cold inner tank 3 are connected to each other through a hose, and the cold inner tank 3 and the cold water connector 6 are connected to each other through a cold water pump. The cold water pump is used to extract water in the cold inner tank 3 into the water collecting box 5. The drinking water in the water tank 2 is transported to the cold inner tank 3 through a pressure difference. The temperature in the cold inner tank 3 can cool the drinking water at room temperature into ice water. The ice water in the cold inner tank 3 is pumped into the water collecting box 5 through the cold water pump. The water collecting box 5 is provided with an outlet, and the ice water flows out through the outlet.

[0020] like Figure 2 As shown, a heat pump is provided between the heating body 4 and the water tank 2, and the heating body 4 and the hot water connector 7 are also connected to each other through a hose. The heat pump is used to pump the water in the water tank 2 into the water collecting box 5. The water in the water tank 2 is pumped into the heating body 4 through the heat pump. The temperature of the drinking water is increased by the heating of the heating body 4 and becomes hot water. Then the hot water flows into the water collecting box 5 through the hose and flows out through the outlet. Through the above arrangement, the machine body 1 can realize the function of discharging cold water or hot water through one outlet.

[0021] like Figure 2 As shown, a bottled water interface and a water purifier interface are provided on one side of the body 1, and a solenoid valve is also provided in the body 1. The water purifier interface is connected to one end of the solenoid valve through a hose, and the other end of the solenoid valve is connected to the water tank 2. Drinking water can be added to the water tank 2 by opening the solenoid valve. The water entering the water purifier interface enters through an external water purification device. A water pump is also provided in the body 1. One end of the water pump is connected to the bottled water interface through a hose, and the other end of the water pump is connected to the water tank 2. When an abnormality occurs in the water company, people can connect bottled water to the bottled water interface, and use the water pump to suck drinking water from the barrel into the water tank 2 to replenish the drinking water in the water tank 2.

[0022] like Figure 2 and Figure 3 As shown, the water collecting box 5 includes a box body and a box cover 8, one of the inner walls of the box body is a guide wall 9, the cold water connector 6 and the hot water connector 7 are both arranged at the upper end of the guide wall 9, and the opening on the box body is located at the lower end of the guide wall 9. The guide wall 9 guides the drinking water so that the drinking water can flow out from the outlet along the guide wall 9. A barrier wall 10 is integrally formed on the outer side of the guide wall 9, and a reflux chamber 11 is formed between the barrier wall 10 and the guide wall 9. The reflux chamber 11 is provided with reflux cooling water. In this water dispenser, there is one ice water gear selection button, and there are 5 hot water gear selection buttons through the heating body 4, which are as follows: Normal temperature water is 25℃, milk is 45℃, honey water is 65℃, coffee is 85℃, boiling water is 100℃, and the water output also has 5 levels, namely 100ml, 150ml, 230ml, 300ml and 500ml. People control the temperature and amount of drinking water entering the water collecting box 5 by controlling the water output and the water output temperature. When people adjust the water output to 100ml or 150ml and select the ice water level, the cooling water in the reflux chamber 11 will flow, and the flowing cooling water will take away the heat on the guide wall 9, thereby ensuring the temperature of the inner wall of the water collecting box 5 and ensuring the taste of the ice water flowing out.

[0023] like Figure 2As shown, a water storage box is also provided between the heat pump and the water tank 2, a locking valve is provided between the water storage box and the water tank 2, the reflux chamber 11 is connected to the water tank 2 by a hose, a reflux pump is provided between the reflux chamber 11 and the water storage box, the reflux pump can pump the liquid in the reflux chamber 11 into the water storage box, the water storage box is located below the water tank 2, the water in the water tank 2 first enters the water storage box for storage, the heat pump draws the drinking water in the water storage box into the heating body 4 for heating, and then drains it into the water collecting box 5, the water storage box serves as an intermediate box between the water tank 2 and the heat pump, the locking valve is closed in normal state, when the water dispenser needs to output hot water, the locking valve is opened, driven by the heat pump, the drinking water enters the water storage box from the water tank 2 and then passes through the heating body 4, wherein the heat pump is located below the water storage box, so that the water in the water tank 2 enters the water storage box under the action of the pressure difference. , the water in the water storage box contacts with the hot water pump under the action of pressure difference. When the water in the reflux chamber 11 needs to reflux, the water in the water tank 2 is pumped into the reflux chamber 11 by the reflux pump, and then the water in the reflux chamber 11 is introduced into the water storage box. If the water dispenser first outputs high-temperature hot water and the hot water output is relatively large, such as 300ml or 500ml, the temperature on the guide wall 9 is relatively high, and the water in the reflux chamber 11 will take away the heat on the guide wall 9, and then flow into the water storage box. Under the action of the locking valve, the water in the water storage box will not be mixed with the water in the water tank 2, so that the water in the flow storage box has a certain temperature. If people need to use hot water immediately later, this part of water will be drawn out from the water storage box. Because this part of water itself has the heat taken away from the water collecting box 5, it can reduce the heating time of the heating body 4 and improve the heat utilization rate.

[0024] like Figure 3 As shown, a baffle 12 inserted into the box body is fixedly connected to the inner wall of the box cover 8, and the baffle 12 is used to slow down the flow rate of the liquid sprayed from the hot water joint 7 or the cold water joint 6. There is a gap between the lower end of the baffle 12 and the inner wall of the box cover 8, and a partition plate 13 is integrally formed in the box body. There is a gap between the top of the partition plate 13 and the box cover 8, and the partition plate 13 divides the outlet into a water outlet 14 and an air outlet 15. When hot water enters the box body through the hot water joint 7, it will first be blocked by the baffle 12, so that the hot water can flow down along the guide wall 9. In the process of hot water flowing, the hot steam will slowly rise through the space between the partition plate 13 and the box cover 8 and flow out from the air outlet 15, while the hot water flows out from the water outlet 14 along the guide wall 9. By arranging the baffle 12 and the partition plate 13, water vapor separation can be achieved in the water collecting box 5, and the hot steam and hot water flow out from different outlets, which can reduce scalding.

[0025] like Figure 3As shown, a protective shell 16 is fixedly connected to the side of the box cover 8 facing away from the box body, and a condensation chamber 17 is formed between the protective shell 16 and the box cover 8. A liquid inlet joint 18 and a liquid outlet joint 19 are respectively provided at both ends of the condensation chamber 17. The liquid inlet joint 18 and the liquid outlet joint 19 are both connected to the cold liner 3. A condensation pump is provided between the liquid inlet joint 18 and the cold liner 3. The condensation pump provides power for the circulation of the liquid in the condensation chamber 17. The liquid in the condensation chamber 17 releases the heat in the liquid into the cold liner 3 through the cold liner 3, thereby ensuring that the liquid in the condensation chamber 17 is always in a low temperature state. The condensation chamber 17 can keep the box cover 8 in a low temperature state. The hot vapor rises to the position of the box cover 8 and is liquefied by the cold, thereby becoming liquid and dripping. This can not only reduce the amount of water vapor floating out, but also the dripping liquid can flow out from the water outlet 14. When people press the water outlet button, the condensation pump will start, and by reducing the amount of steam flowing out, the occurrence of scalding can be further reduced. A number of water collecting protrusions 20 are arranged on the inner side of the box cover 8. The water collecting protrusions 20 are arranged in an inverted cone shape. A number of water collecting protrusions 20 are located between the baffle 12 and the partition plate 13. After the water vapor condenses on the inverted cone-shaped water collecting protrusions 20, the formed water droplets are easier to fall. The surface of the inverted cone has a larger inclination angle, which can help the water droplets slide downward, making it easier for the condensed water droplets to fall. This arrangement allows as many water droplets as possible to flow out of the water outlet 14 together with the hot water.

[0026] like Figure 4As shown, the cold liner 3 includes an inner tank 21 and an outer shell 22. The inner tank 21 is provided with an inner cavity for storing drinking water. A refrigeration cavity 23 is formed between the outer shell 22 and the inner tank 21. A refrigeration copper tube 24 is provided in the refrigeration cavity 23. The refrigeration copper tube 24 is serpentinely wound around the inner tank 21. A refrigeration system is provided in the body 1. The refrigeration system is used to transport the refrigerant into the refrigeration copper tube 24. The refrigeration system includes a compressor and a condenser. The compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant. After the high-temperature and high-pressure refrigerant enters the condenser to dissipate heat, it becomes a low-temperature and high-pressure liquid refrigerant. After the refrigerator enters the refrigeration copper tube 24, the high-pressure state is released and the surrounding heat is absorbed, thereby playing a refrigeration role. The refrigeration copper tube 24 converts the heat of the cold liner 3 into a liquid state. The amount of liquid absorbed by the liner tank 21 is refrigerated. The cold liner 3 also includes a serpentine tube 25 located in the refrigeration chamber 23. The serpentine tube 25 is fitted with the refrigeration copper tube 24. One end of the serpentine tube 25 is connected to the liquid outlet joint 19, and the other end of the serpentine tube 25 is connected to the liquid inlet joint 18 through a condensation pump. The serpentine tube 25 and the condensation chamber 17 are full of liquid. Through the action of the condensation pump, the liquid in the condensation chamber 17 passes through the refrigeration chamber 23, and the refrigeration copper tube 24 can absorb the temperature in the serpentine tube 25, so that the liquid in the condensation chamber 17 always maintains a low temperature state. Because the serpentine tube 25 is located in the refrigeration chamber 23 and has a large fitting area with the refrigeration copper tube 24, the liquid can dissipate heat during the flow of the serpentine tube 25, thereby ensuring the heat dissipation efficiency of the serpentine tube 25.

[0027] like Figure 4 As shown, an exhaust pipe 26, a water outlet pipe 27 and a water inlet pipe 28 are arranged on the top surface of the inner tank 21, and a water distribution plate 29 located in the inner tank 21 is fixedly connected to the water outlet pipe 27. The exhaust pipe 26 and the water inlet pipe 28 are both located on the upper side of the water distribution plate 29, and the lower end of the water outlet pipe 27 is located at the lower end of the inner tank 21. An exhaust interface is also arranged on the side wall of the body 1, and the exhaust interface is connected to the exhaust pipe 26. The gas in the inner tank 21 is discharged through the exhaust interface. The water in the water tank 2 enters the inner tank 21 and has a certain impact force under the action of gravitational potential energy. The water distribution plate 29 can buffer this part of the impact force, so that the impact force of the water rushing into the inner tank 21 is small, so that the water just entering the inner tank 21 is not easy to impact the position of the lower layer of water in the inner tank 21, thereby ensuring the temperature of the lower layer of water. The water inlet pipe 28 is used to extract the cold water from the lower layer of the inner tank 21.

[0028] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
