Description

Technical Field

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

[0002] An embedded water dispenser is a drinking water device that embeds the water dispenser equipment into the wall or furniture of the kitchen, office or other spaces, so that it can be integrated with the surrounding environment. This design is usually aimed at saving space and enhancing aesthetics, especially 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. It can not only provide hot drinking water but also ice drinking water. The water dispenser includes a water tank and a cold inner tank, which are interconnected. The water in the cold inner tank is cooled by a compressor, so that the drinking water in the cold inner tank reaches the ice state. Then, the ice water is pumped from the cold inner tank into the water collection box by a cold water pump. There is a water outlet under the water collection box, and cold water can directly flow out from the water outlet. A heating element is also provided in the water dispenser. One end of the heating element is connected to the water tank through a hot water pump, and the other end of the heating element is connected to the water collection box. The water in the water tank enters the heating element through the hot water pump, is heated and then enters the water collection box, and then flows out from the water outlet. By controlling the cold water pump and the hot water pump, it is possible to control whether the water flowing out from the water outlet is ice water or hot water.

[0004] Everyone has different requirements for the temperature of the water obtained from the water dispenser. After the water dispenser has dispensed hot water, the temperature of the hot water will conduct to the inner wall of the water collection box, resulting in a relatively high temperature on the inner wall of the water collection box. 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 collection box when it enters the water collection box, resulting in an increase in the temperature of the ice water, so that the temperature of the water flowing out from the water outlet cannot meet people's needs.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an embedded water dispenser.

A hot water connector and a cold water connector are provided on the water collection box. The water tank and the cold inner tank are connected to each other through a hose. The cold inner tank and the cold water connector are connected to each other through a cold water pump. The cold water pump is used to pump the water in the cold inner tank into the water collection box. A hot water pump is provided between the heating element and the water tank. The heating element and the hot water connector are also connected to each other through a hose. The hot water pump is used to pump the water in the water tank into the water collection box;

[0008] The water collection box includes a box body and a box cover. One inner wall of the box body is a diversion wall. The cold water connector and the hot water connector are both provided at the upper end of the diversion wall. An outlet is provided on the box body at the lower end of the diversion wall. A blocking wall is integrally formed on the outer side of the diversion wall. A return cavity is formed between the blocking wall and the diversion wall.

[0009] The present invention is further provided as follows: A water storage box is further provided between the hot water pump and the water tank. A locking valve is provided between the water storage box and the water tank. The return cavity and the water tank are connected through a hose. A return pump is provided between the return cavity and the water storage box. The return pump can pump the liquid in the return cavity into the water storage box.

[0010] The present invention is further provided as follows: A flow blocking plate inserted into the box body is fixedly connected to the inner wall of the box cover. The flow blocking plate is used to slow down the flow rate of the liquid ejected from the hot water connector or the cold water connector. A partition plate is integrally formed in the box body. There is a space between the partition plate and the box cover. The partition plate divides the outlet into a water outlet and a gas outlet.

[0011] The present invention is further provided as follows: A protective shell is fixedly connected to the side of the box cover facing away from the box body. A condensation cavity is formed between the protective shell and the box cover. A liquid inlet connector and a liquid outlet connector are respectively provided at both ends of the condensation cavity. The liquid inlet connector and the liquid outlet connector are both connected to the cold inner tank. A condensation pump is provided between the liquid inlet connector and the cold inner tank.

[0012] The present invention is further provided as follows: A number of water collection bumps are provided on the inner side of the box cover. The water collection bumps are arranged in an inverted cone shape. A number of the water collection bumps are located between the flow blocking plate and the partition plate.

[0013] The present invention is further provided as follows: The cold inner tank includes an inner tank and an outer shell. An inner cavity for storing drinking water is provided in the inner tank. A refrigeration cavity is formed between the outer shell and the inner tank. A refrigeration copper tube is provided in the refrigeration cavity. The refrigeration copper tube is wound around the outer side of the inner tank in a snake shape. A refrigeration system is provided in the body. The refrigeration system is used to transport the refrigerant into the refrigeration copper tube.

[0014] The present invention is further configured such that: a serpentine tube is further included in the cold inner liner and is located in the refrigeration chamber. The serpentine tube is attached to the refrigeration copper tube. One end of the serpentine tube is connected to the liquid outlet joint, and the other end of the serpentine tube is connected to the liquid inlet joint through the condensation pump.

[0015] The present invention is further configured such that: an exhaust pipe, a water outlet pipe, and a water inlet pipe are provided on the top surface of the inner liner tank. A water distribution plate located inside the inner liner tank is fixedly connected to the water outlet pipe. Both the exhaust pipe and the water inlet pipe are located above the water distribution plate.

[0016] In summary, the present invention has the following beneficial effects:

[0017] When the water output of the water dispenser is relatively small and the ice water gear is selected, the cooling water in the reflux chamber will flow. The flowing cooling water will carry away the heat on the diversion wall, thereby ensuring the temperature of the inner wall of the water collection box, so that the temperature of the inner wall of the water collection box will not cause a large change in the temperature of the ice water, and the taste of the flowing ice water is guaranteed.

[0018] The water in the reflux chamber will carry away the heat on the diversion wall 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. If people need to immediately use hot water later, this part of the water will be pumped out from the water storage box. Since this part of the water itself has the heat carried away from the water collection box, the heating time of the heating element can be reduced, and the thermal utilization rate can be improved.

[0019] The condensation chamber can keep the lid in a low-temperature state. When the hot steam rises to the position of the lid, it will be cooled and liquefied, and thus becomes liquid and drips down. In this way, not only the amount of steam escaping can be reduced, but the dripping liquid can also flow out from the water outlet. Description of the Drawings

[0025] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] An embedded water dispenser, as Figure 1 and Figure 2 shown, includes a body 1, in which there are arranged a water tank 2, a cold inner tank 3, a heating element 4 and a water collection box 5. A hot water connector 7 and a cold water connector 6 are arranged on the water collection box 5. The water tank 2 and the cold inner tank 3 are connected to each other by a hose. The cold inner tank 3 and the cold water connector 6 are connected to each other by a cold water pump. The cold water pump is used to pump the water in the cold inner tank 3 into the water collection box 5. The drinking water in the water tank 2 is transported to the cold inner tank 3 through the pressure difference. Inside the cold inner tank 3, the temperature can cool the normal-temperature drinking water into ice water, and the ice water in the cold inner tank 3 is pumped into the water collection box 5 by the cold water pump. There is an outlet in the water collection box 5, and the ice water flows out through the outlet.

[0027] As Figure 2 shown, there is a hot water pump between the heating element 4 and the water tank 2. The heating element 4 and the hot water connector 7 are also connected to each other by a hose. The hot water pump is used to pump the water in the water tank 2 into the water collection box 5. The water in the water tank 2 is pumped into the heating element 4 by the hot water pump. Through the heating of the heating element 4, the temperature of the drinking water rises to become hot water, and then the hot water flows into the water collection box 5 through the hose and flows out through the outlet. Through the above settings, the body 1 can realize the function of discharging cold water or hot water through one outlet.

[0028] As Figure 2 shown, a barreled water interface and a water purifier interface are arranged on one side of the body 1. An electromagnetic valve is also arranged inside the body 1. The water purifier interface is connected to one end of the electromagnetic valve by a hose, and the other end of the electromagnetic valve is connected to the water tank 2. By opening the electromagnetic valve, drinking water can be replenished into the water tank 2. The water entering the water purifier interface enters through an external water purification device. A water pump is also arranged inside the body 1. One end of the water pump is connected to the barreled water interface by a hose, and the other end of the water pump is connected to the water tank 2. When there is an abnormality in the water supply company, people can connect the barreled water to the barreled water interface, and the drinking water is sucked from the barrel into the water tank 2 through the water pump to realize the replenishment of the drinking water in the water tank 2.

[0029] As Figure 2 and Figure 3 shown, the water collection box 5 includes a box body and a box cover 8. One of the inner walls of the box body is a diversion wall 9. Both the cold water joint 6 and the hot water joint 7 are arranged at the upper end of the diversion wall 9. The opening on the box body is located at the lower end of the diversion wall 9. The diversion wall 9 guides the drinking water, so that the drinking water can flow out from the outlet along the diversion wall 9. A partition wall 10 is integrally formed on the outer side of the diversion wall 9. A return cavity 11 is formed between the partition wall 10 and the diversion wall 9. The return cavity 11 is provided with cooled water for return. In this water dispenser, there is 1 ice water gear selection button, and there are 5 kinds of hot water gear selection buttons for the heated body 4, which are 25°C of normal temperature water, 45°C of milk, 65°C of honey water, 85°C of coffee, and 100°C of boiling water in sequence. The water output also has 5 gears, which are 100ml, 150ml, 230ml, 300ml, and 500ml in sequence. People control the temperature and quantity of the drinking water entering the water collection box 5 by controlling the water output and the water outlet temperature. When people adjust the water output to 100ml or 150ml and select the ice water gear, the cooled water in the return cavity 11 will flow, and the flowing cooled water will take away the heat on the diversion wall 9, so as to ensure the temperature of the inner wall of the water collection box 5 and ensure the taste of the flowing ice water.

[0030] As Figure 2As shown in the figure, a water storage box is also provided between the hot water pump and the water tank 2. A locking valve is provided between the water storage box and the water tank 2. The return cavity 11 is connected to the water tank 2 through a hose. A return pump is provided between the return cavity 11 and the water storage box. The return pump can pump the liquid in the return cavity 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. After the hot water pump pumps the drinking water in the water storage box into the heating body 4 for heating, it is then diverted to the water collection box 5. The water storage box serves as an intermediate box between the water tank 2 and the hot water pump. Under normal circumstances, the locking valve is closed. When the water dispenser needs to supply hot water, the locking valve opens. Driven by the hot water pump, the drinking water enters the water storage box from the water tank 2 and then passes through the heating body 4. The hot water 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 the hot water pump under the action of the pressure difference. When the water in the return cavity 11 needs to flow back, the water in the water tank 2 is pumped into the return cavity 11 through the return pump, and then the water in the return cavity 11 is introduced into the water storage box. If the water dispenser first dispenses high-temperature hot water and the hot water output is relatively large, such as 300 ml or 500 ml, the temperature on the diversion wall 9 is relatively high. The water in the return cavity 11 will take away the heat on the diversion 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 storage box has a certain temperature. If people need to immediately use hot water later, this part of the water will be pumped out of the water storage box. Because this part of the water itself has the heat taken away from the water collection box 5, the heating time of the heating body 4 can be reduced, and the heat utilization rate can be improved.

[0031] As Figure 3 As shown in the figure, a baffle 12 inserted into the box body is fixedly connected to the inner wall of the box cover 8. The baffle 12 is used to slow down the flow rate of the liquid ejected 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. 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. 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 diversion wall 9. During the flow of the hot water, 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 diversion wall 9. By setting the baffle 12 and the partition plate 13, water-vapor separation can be achieved in the water collection box 5, and the hot steam and the hot water flow out from different outlets, which can reduce the situation of scalding.

[0032] As Figure 3As shown, a protective shell 16 is fixedly connected to the side of the box cover 8 facing away from the box body. A condensation chamber 17 is formed between the protective shell 16 and the box cover 8. Liquid inlet connectors 18 and liquid outlet connectors 19 are respectively provided at both ends of the condensation chamber 17. Both the liquid inlet connectors 18 and the liquid outlet connectors 19 are connected to the cold inner tank 3. A condensation pump is provided between the liquid inlet connector 18 and the cold inner tank 3. The condensation pump provides power for the circulation of the liquid in the condensation chamber 17. The liquid in the condensation chamber 17 passes through the cold inner tank 3, releasing the heat in the liquid into the cold inner tank 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 will be cooled and liquefied, thus turning into liquid droplets and dripping down. 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, further reducing the occurrence of scalding by reducing the amount of vapor flowing out. A number of water collection bumps 20 are provided on the inner side of the box cover 8. The water collection bumps 20 are arranged in an inverted cone shape. The number of water collection bumps 20 is located between the flow blocking plate 12 and the partition plate 13. After the water vapor condenses on the inverted cone-shaped water collection bumps 20, the formed water droplets are more likely to fall. The surface of the inverted cone shape has a large inclination angle, which can help the water droplets slide downward, making the condensed water droplets more likely to fall. This setting enables as many water droplets as possible to flow out from the water outlet 14 together with the hot water.

[0033] As 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.

[0034] 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.

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.
