The invention provides a water dispenser.

In an embodiment of the present invention, as shown in fig. 1 to 3, the water dispenser includes: a cold water tank 11; the refrigeration assembly comprises a refrigeration box 21 and a refrigeration heat exchanger 22 arranged corresponding to the refrigeration box 21, the refrigeration box 21 is communicated with the cold water tank 11 through a pipeline, and the pipeline is provided with a circulating pump 30 so that water can circularly flow between the cold water tank 11 and the refrigeration box 21; the water replenishing tank 40 is arranged in the cold water tank 11, is communicated with a water source and is used for replenishing water to the cold water tank 11; a hot water tank 50, wherein the hot water tank 50 is communicated with the water replenishing tank 40, so that the water replenishing tank 40 replenishes water to the hot water tank 50.

In the present embodiment, a pipeline connects the cold water tank 11 and the refrigeration cassette 21, and the circulation pump 30 is disposed on the pipeline to deliver water in the cold water tank 11 to the refrigeration cassette 21. The refrigeration heat exchanger 22 is an evaporator, the refrigeration heat exchanger 22 is arranged inside or above the refrigeration box 21, and if the refrigeration heat exchanger 22 is arranged above the refrigeration box 21, water in the cold water tank 11 firstly flows through the refrigeration heat exchanger 22 for heat exchange and refrigeration and then falls to the refrigeration box 21; if the refrigeration heat exchanger 22 is disposed inside the refrigeration cassette 21, the water inside the refrigeration cassette 21 can be subjected to refrigeration heat exchange. After being refrigerated by the refrigeration heat exchanger 22 to form cold water, the water flows back to the cold water tank 11, either through the circulating pump 30 or through other methods, and only the requirement that the water can flow between the cold water tank 11 and the refrigeration box 21 is met. In the process of refrigerating water, because the water is in a flowing state, the water exchanging heat with the refrigerating heat exchanger 22 is not easy to freeze, and the whole water temperature of the cold water tank 11 is reduced through flowing, so that the cold water is effectively prepared.

The water replenishing tank 40 can replenish water toward the cold water tank 11 in an overflowing manner, namely, the water replenishing tank 40 and the cold water tank 11 are kept in a communicated state, so that water at a water source can be supplied to the water replenishing tank 40, and the water replenishing tank 40 can overflow to the cold water tank 11 after being full of water, so that water can be replenished to the cold water tank 11 from the inside of the cold water tank 11, a water replenishing pipeline between the cold water tank 11 and the water replenishing tank 40 is omitted, and the water replenishing tank 40 can be kept in a full-water state after water replenishing is finished. The hot water tank 50 is arranged outside the cold water tank 11 and is communicated with the water replenishing tank 40 through a pipeline, so that the water replenishing water paths of the hot water tank 50 and the cold water tank 11 can be mutually independent, water replenishing errors are avoided, and the stability of the water replenishing process is improved.

According to the water dispenser, the water replenishing tank 40 is arranged in the cold water tank 11, so that water can be directly replenished from the inside of the cold water tank 11, a pipeline for communicating the cold water tank 11 with the water replenishing tank 40 is omitted, and water replenishing paths of the water replenishing tank 40 to the cold water tank 11 and the hot water tank 50 are mutually independent, so that water replenishing errors can be avoided, and the practicability and the stability of the water dispenser are improved.

In an embodiment, as shown in fig. 1, a thermal insulation boss 12 is protruded from a bottom of the cold water tank 11, and the water replenishing tank 40 is disposed on the thermal insulation boss 12. In this embodiment, separate temperature boss 12 and be used for increasing the mounting height of moisturizing case 40 in cold water tank 11 to reduce the contact volume of moisturizing case 40 and cold water, avoid the water of moisturizing case 40 and the water heat transfer cooling of cold water tank 11, thereby avoid getting into the temperature degree of hot-water tank 50 and cross lowly, make hot-water tank 50 effectively form hot water, improve hot-water tank 50 and go out water temperature's stability.

In one embodiment, as shown in fig. 1, the hot water tank 50 is disposed below the cold water tank 11, so that the water in the water supply tank 40 flows to the hot water tank 50 by gravity. In the present embodiment, the hot water tank 50 and the water replenishing tank 40 are kept in a communication state, and the water level of the water replenishing tank 40 rises only after the hot water tank 50 is full of water, so that the hot water tank 50 can be kept in a full water state, and the heating element in the hot water tank 50 is prevented from being dried.

Specifically, the refill tank 40 is communicated with a water source through a water supply pump 41, and a float switch electrically connected to the water supply pump 41 is further provided in the refill tank 40 to activate the water supply pump 41 according to a water level change of the refill tank 40. In this embodiment, when the water replenishing tank 40 replenishes water to the hot water tank 50, the amount of water in the water replenishing tank 40 is reduced, the water level is lowered, the float switch is used for detecting the water level change of the water replenishing tank 40, and once the float switch detects the water level reduction of the water replenishing tank 40, the float switch controls the operation of the water supply pump 41 to supply water to the water replenishing tank 40 in time, so as to prevent the hot water tank 50 from yielding water too fast to cause untimely water replenishing of the water replenishing tank 40, thereby avoiding dry burning of the heating element. Therefore, the water replenishing opportunity of the hot water pipe can be more timely, and the stability of the water replenishing process is improved.

In one embodiment, as shown in fig. 1, the water dispenser further includes a water intake valve 51 in communication with the hot water tank 50, wherein the water intake valve 51 takes water at a flow rate greater than the water supply flow rate of the water supply pump 41. In the present embodiment, when the hot water tank 50 is drained, the water replenishing tank 40 replenishes water to the hot water tank 50 simultaneously, and the water supply pump 41 supplies water to the water replenishing tank 40 accordingly, that is, the water drained from the hot water tank 50 and the water supplied by the water supply pump 41 are performed simultaneously. The water intake flow rate of the water intake valve 51 is the water outlet flow rate of the hot water tank 50, and if the water intake flow rate of the water intake valve 51 is smaller than the water supply flow rate of the water supply pump 41, the water level of the water supply tank 40 rises to overflow the water supply tank 40 in the process of supplying water to the hot water tank 50, so that the water overflows to the cold water tank 11, and the water level and the water temperature of the cold water tank 11 are influenced; therefore, the water intake flow rate of the water intake valve 51 should be greater than the water supply flow rate of the water supply pump 41 to prevent the water replenishing tank 40 from overflowing during the water replenishing process of the hot water tank 50, thereby improving the stability of the water replenishing process.

Specifically, the effective volume of the replenishing water tank 40 is not less than the product of the difference between the water intake flow rate of the water intake valve 51 and the water supply flow rate of the water supply pump 41 and the preset water intake time period of the water intake valve 51. In this embodiment, the preset water intake time of the water intake valve 51 is the maximum water outlet time of the hot water tank 50, and if the water intake time of the user exceeds the preset water intake time, the water intake valve 51 will automatically close to stop water outlet, so as to provide the water supply time for the water replenishing tank 40. The product of the difference between the water intake flow rate of the water intake valve 51 and the water supply flow rate of the water supply pump 41 and the preset water intake time of the water intake valve 51 is the amount of compensation water for keeping the hot water tank 50 in a full water state during the water supply process to the hot water tank 50. In the water replenishing process of the water replenishing tank 40, water outlet and water inlet are carried out simultaneously in the water replenishing tank 40, the water flow rate of the water replenishing tank 40 is greater than the water inlet flow rate, so that the water quantity of the water replenishing tank 40 is in a dynamically reduced state, the water replenishing tank 40 is in a full water state before water replenishing, and the water is used as the compensation water quantity for replenishing water to the hot water tank 50, so that the effective volume of the water replenishing tank 40 at least needs to be the compensation water quantity, the hot water tank 50 can be kept in the full water state in the water outlet process of the hot water tank 50, the heating element in the hot water tank 50 is prevented from being burnt, and the stability.

In practical applications, the effective volume of the makeup tank 40 is not greater than 1/40 of the effective volume of the cold water tank 11. In the embodiment, if the effective volume of the water replenishing tank 40 is too large, the water in the water replenishing tank 40 exchanges heat with the cold water tank 11 to form a large amount of cold water, and if the cold water replenishes the hot water tank 50, the temperature of the water entering the hot water tank 50 is too low, so that the finally formed hot water cannot reach the preset temperature. Therefore, the effective volume of the water replenishing tank 40 is set to 1/40 which is not larger than the effective volume of the cold water tank 11, so that the temperature of water entering the hot water tank 50 is prevented from being too low, the hot water tank 50 can effectively form hot water, and the stability of the outlet water temperature of the hot water tank 50 is improved.

In one embodiment, as shown in fig. 2 and 3, the water replenishing tank 40 has an overflow 43 for overflowing water in the water replenishing tank 40 to the cold water tank 11, and the overflow 43 is higher than a full water level of the cold water tank 11. In this embodiment, if the water level of the cold water tank 11 reaches the full water level, the water replenishment may be stopped. The full water level is lower than the overflow opening 43 of the water replenishing tank 40, so that the water in the cold water tank 11 can be prevented from flowing back to the water replenishing tank 40 in the process of replenishing water for the hot water tank 50 in the water replenishing tank 40, thereby further preventing cold water from entering the hot water tank 50, enabling the hot water tank 50 to effectively form hot water and improving the stability of the outlet water temperature of the hot water tank 50.

Specifically, a water level up switch electrically connected to the water supply pump 41 is provided in the cold water tank 11 to detect a full water state of the cold water tank 11, and the water supply pump 41 can stop supplying water in time according to the water volume of the water tank by electrically connecting the water level up switch to the water supply pump 41, thereby achieving stability of water supply.

In an embodiment, as shown in fig. 2 and 3, a partition 13 is disposed in the cold water tank 11, the partition 13 divides the cold water tank 11 into a cold water region 111 and a water mixing region 112, and the overflow 43 of the water supplement tank 40 is disposed corresponding to the water mixing region 112, so that water flowing out of the overflow 43 flows to the water mixing region 112;

the cold water tank 11 is provided with a heat exchange water outlet 113 communicated with the refrigeration box 21 and a water intake 114 communicated with the water intake device 70, the heat exchange water outlet 113 is arranged in the water mixing area 112 and/or the cold water area 111, and the water intake 114 is arranged in the cold water area 111.

In the embodiment, the front side of the partition 13 extends toward the water replenishing tank 40 to be connected to the water replenishing tank 40, so that the overflow 43 can accurately correspond to the water mixing area 112, normal temperature water firstly enters the water mixing area 112, and cold water firstly enters the cold water area 111, so that the water temperature of the water mixing area 112 is higher than that of the cold water area 111. The water intake port 114 is in communication with the cold water region 111, which allows the user to take more and more timely cold water. The heat exchange water outlet 113 corresponds to the water mixing area 112, so that water with relatively high temperature in the water mixing area 112 can be subjected to heat exchange refrigeration, and the refrigeration efficiency of the whole water in the cold water tank 11 is improved.

Specifically, as shown in fig. 1, the water dispenser further includes an inner container 10, the cold water tank 11 is formed at the bottom of the inner container 10, and the refrigeration assembly is disposed at the top of the inner container 10 and above the cold water area 111, so that the water of the refrigeration box 21 flows to the cold water area 111. In this embodiment, the cold water tank 11 and the refrigeration component are integrated in the inner container 10, so that the overall structure of the water dispenser is more compact. The pipeline is communicated with the cold water tank 11 and the refrigeration box 21 from the outside of the inner container 10 so as to reduce the space occupation of the inner container 10. The circulation pump 30 pumps water in the cold water tank 11 to the refrigeration cassette 21, and the refrigeration cassette 21 overflows to the cold water tank 11 under the action of gravity after being filled with water, so that the water can circulate between the cold water tank 11 and the refrigeration cassette 21. The refrigeration heat exchanger 22 is suspended in the refrigeration box 21, and after the water entering the refrigeration box 21 exchanges heat with the refrigeration heat exchanger 22 to form cold water, the cold water overflows back to the cold water area 111 below, so that the water in the cold water area 111 is cooled.

In practical application, as shown in fig. 2 and 3, a water passing gap 131 is formed between the partition plate 13 and the inner wall of the cold water tank 11, and the water passing gap 131 communicates the cold water region 111 and the water mixing region 112. In this embodiment, a water passing gap 131 is formed between the rear side of the partition 13 and the inner wall of the cold water tank 11, so that the water level of the cold water region 111 and the water level of the water mixing region 112 can be maintained at the same level, thereby preventing the water amount from being uneven.

In an embodiment, as shown in fig. 1, the refrigeration heat exchanger 22 can be used for making ice, and the water dispenser further includes an ice storage tray 60 disposed in the inner container 10, wherein the ice storage tray 60 is located above the cold water tank 11 and is used for receiving ice pieces separated from the refrigeration cassette 21. In this embodiment, the water dispenser has a water making condition and an ice making condition, and the circulation pump 30 continuously operates under the water making condition, so that the water in the cold water tank 11 continuously flows to the refrigeration box 21 and then overflows back to the cold water tank 11, and the water in the cold water tank 11 is integrally cooled.

Under the ice making condition, the circulating pump 30 intermittently operates to effectively freeze the water in the refrigeration box 21, and after the ice blocks are separated from the refrigeration box 21 and conveyed to the ice storage tray 60, the circulating pump 30 timely operates to add water to the refrigeration box 21 to make the next ice. The ice pieces within the refrigeration cassette 21 may be removed from the refrigeration cassette 21 and transported to the ice storage tray 60 by toggling of the refrigeration cassette 21 or the ice-plucking structure. The ice storage tray 60 is located at one side of the refrigeration cassette 21 to prevent the backflow of cold water from being hindered by the water-making condition. Therefore, the water dispenser has the ice making function, the user requirements are met, and the practicability of the water dispenser is improved.
