Description

Technical Field

[0001] This utility model relates to the field of ice tank technology for water dispensers, and in particular to an ice tank structure for a water dispenser and the water dispenser thereof. Background Technology

[0002] Existing water dispensers use an ice tank with the refrigeration pipes located outside the cooling chamber. The refrigeration pipes freeze the water inside for drinking. However, because the refrigeration pipes are external, even with an insulation layer, they still absorb some heat from the surrounding environment, affecting cooling efficiency. Patent CN2652291Y discloses a water dispenser with an internal refrigeration pipe ice tank. By placing the refrigeration pipes inside the ice tank, the pipes are in full contact with the water being cooled, thus improving cooling efficiency.

[0003] However, since the refrigeration pipe is suspended in the tank, the natural convection of water is slow, which easily leads to temperature stratification (cold water sinks and hot water stays), prolonging the refrigeration process and wasting cooling capacity. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of insufficient cold energy utilization in existing ice tanks, which leads to temperature stratification of the water inside the tank, and to provide a water dispenser ice tank structure and a water dispenser thereof.

[0009] Furthermore, the upper part of the hollow cylinder is provided with a notch, the height of which is higher than the upper end of the guide plate; the bottom side wall of the hollow cylinder is provided with a through hole group for connecting the bottom of the hollow liner and the bottom of the hollow cylinder.

This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0022] Example 1

[0023] like Figures 1-4 As shown, a water dispenser ice tank structure includes a hollow tank 1, which is a cylindrical stainless steel container with stamped end caps sealing the top and bottom. The inner wall is polished to reduce water flow resistance, and the outer wall is wrapped with polyurethane foam as an insulation layer. The upper part of the hollow tank 1 is equipped with an inlet pipe 12, located on the top right side, made of DN15 stainless steel, extending downwards to 50mm above a spiral guide plate 3 to guide the water flow into a vortex. An outlet pipe 11 is located on the top left side, also made of DN15 stainless steel, with its bottom opening extending 20mm below the spiral guide plate 3 to directly draw cold water from the bottom. The bottom of the hollow tank 1 is equipped with a drain pipe 13, located at the bottom center, made of DN20 stainless steel, connected to a solenoid valve (not labeled), used to drain accumulated water and impurities from the tank. The inlet pipe 12 and outlet pipe 11 are positioned above and below the guide plate respectively, achieving natural stratified circulation of hot and cold water and avoiding cold energy loss.

[0024] A refrigeration pipe 2 is built inside the hollow liner 1. The refrigeration pipe 2 has a spiral structure, with its inlet and outlet ends located on the upper outer side of the hollow liner 1 and connected to the cooling mechanism. Specifically, the refrigeration pipe 2 is made of copper and is wound in a right-hand spiral around the inner wall of the hollow liner 1. The inlet end 21 and outlet end 22 extend from the top through the upper side wall of the hollow liner 1 to the outside, connecting to the compressor refrigeration system. The interface is sealed with a flange. Through the cooperation of the spiral guide plate 3 and the refrigeration pipe 2 in the same direction of rotation, the water flow path is extended and laminar flow is formed, improving heat exchange efficiency.

[0025] A hollow cylinder 4 is vertically arranged in the center of the hollow liner 1. Specifically, the hollow cylinder 4 is vertically welded to the center of the hollow liner 1, is made of 304 stainless steel, and its height is consistent with the internal height of the hollow liner 1. A through-hole group 41 is provided on the bottom side wall of the hollow cylinder 4. The through-hole group 41 consists of four rows of evenly distributed circular holes, used to connect the bottom of the hollow liner 1 with the interior of the cylinder. A notch 42 is opened on the top side wall of the hollow cylinder 4, with a height 10mm higher than the upper edge of the spiral guide plate 3, to ensure that water can enter the cylinder through the notch 42. A stainless steel circular plate is welded at the notch 42 for mounting the pump 5. In this design, the pump 5 can be connected to an external waterproof wire, which is connected to an external electrical control mechanism that passes through the hollow liner 1.

[0026] The pump 5 is connected to a water inlet pipe 51. The water inlet pipe 51 is made of DN10 stainless steel pipe, which extends vertically from the pump inlet to the bottom of the cylinder. The end of the pipe is 10mm from the bottom and is fitted with a 100-mesh stainless steel filter screen.

[0027] A spiral guide plate 3 is provided on the outside of the hollow cylinder 4; the thread direction of the refrigeration pipe 2 is parallel to the thread direction of the spiral guide plate 3. Specifically, the spiral guide plate 3 is made of food-grade PP plastic sheet and is welded to the outer wall of the hollow cylinder 4 in a right-hand spiral shape. The plates between adjacent spiral guide plates 3 form a water flow channel with the hollow liner 1. The refrigeration pipe 2 passes through the water flow channel and is in close contact with the surface of the spiral guide plate 3. After the water enters from the water inlet pipe 12, it flows downward spirally along the guide plate, forming a uniform water film and prolonging the contact time with the refrigeration pipe 2. The guide plate and the refrigeration pipe 2 are arranged spirally in the same direction to form counter-current heat exchange, improving the refrigeration efficiency.

[0028] This solution includes three paths, as detailed below:

[0029] Water flow path: external cold water → inlet pipe 12 → spiral guide plate 3 forms a vortex → heat exchange with refrigeration pipe 2 → cold water sinks to the bottom of the tank → part of it enters the hollow cylinder 4 through the through hole group 41 → pump 5 extracts and transports it to the outlet pipe 11.

[0030] Refrigerant path: The refrigerant enters the spiral refrigeration pipe 2 from the liquid inlet 21, releases its cooling capacity, and then returns to the compressor from the liquid outlet 22, forming a closed-loop cycle.

[0031] Sewage discharge path: During drainage, the water flows down along the guide plate 3 → through the through hole group 41 into the hollow cylinder 4 → and is discharged from the drain pipe 13.

[0034] The above-described embodiments merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
