Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a cold water tank and beverage equipment. Background Art

[0002] Beverage equipment includes coffee machines, water dispensers and other products. These devices usually have the function of heating or cooling beverages. The cooling function is usually achieved by transporting drinking water to the refrigeration system for cooling and cooling before output. The cold water tank in the refrigeration system has a scenario where it is cooled while entering and exiting. That is, after the refrigeration system cools a tank of cold water, it outputs cold water while inputting normal temperature water for cooling. In this process, normal temperature water and cooling water mix, causing the outlet water temperature to be disordered.

[0003] Chinese patent CN202120501440.0 discloses a carbonation tank with a baffle and a device for preparing sparkling water, including a tank body, a water inlet pipe, a carbon dioxide inlet pipe, a water outlet pipe and a baffle; a refrigeration device is provided on the outer wall of the tank body; the baffle is located near the top of the tank body, with an area smaller than the cross-section of the tank body, and a gap is left between the outer edge and the inner wall of the tank body; the water inlet pipe passes through the top of the tank body, and its outlet is located above the baffle, and the liquid flowing out of the water inlet pipe outlet flows through the baffle, and flows into the tank from the gap between the outer edge of the baffle and the inner wall of the tank body; the carbon dioxide inlet pipe and the water outlet pipe respectively pass through the top of the tank body and the baffle, and the outlet of the carbon dioxide inlet pipe is close to the bottom of the tank body. The blocking effect of the baffle increases the contact area between the unit volume of the liquid flowing out of the water pipe and the inner wall of the tank body, shortens the distance to the inner wall of the tank body, thereby increasing the cooling rate of the liquid in the carbonation tank and improving the refrigeration efficiency of the carbonation tank. However, this solution cannot solve the problem of turbulent outlet water temperature.

[0004] The utility model overcomes the shortcomings of the prior art and provides a cold water tank, which can solve the problem of disordered outlet water temperature. Utility Model Content

[0027] like Figure 1-4 , which is a schematic diagram of an embodiment of a cold water tank provided by the utility model.

[0028] Please refer to Figure 1-4 This embodiment is used for preparing and storing cold water in a refrigeration system, and includes a tank body 1, which is provided with a water inlet 2, a water outlet 3 and a stabilizing plate 4. The stabilizing plate 4 is located inside the tank body 1, the water inlet 2 is located above the stabilizing plate 4, and the stabilizing plate 4 is evenly distributed with a plurality of water guide holes 5. The liquid passes through the water inlet 2 and covers the upper surface of the stabilizing plate 4, and the liquid flows to the bottom of the stabilizing plate 4 through the water guide holes 5 of the stabilizing plate 4.

[0029] In this embodiment, the single fluid input from the water inlet 2 is dispersed into multiple fluids through the guide holes 5. Under the condition of the same flow rate, the water pressure of the multiple fluids is smaller than that of the single fluid, and the multiple water guide holes 5 are evenly distributed above the cooling water body, which increases the contact area between the incoming water (normal temperature water) and the cooling water body, reduces the disturbance of the incoming water on the cooling water body, thereby reducing the degree of heat exchange between the incoming water and the cooling water body, so that the outlet water temperature remains low.

[0030] In one embodiment, the area where the water inlet 2 is projected onto the stabilizing plate 4 is a closed area 41, and the area of ​​the closed area 41 is larger than the inner diameter of the water inlet 2. Specifically, no diversion hole 5 is designed directly opposite the water inlet 2, so that when the water inlet 2 is opened, the room temperature water will quickly diffuse to the upper surface of the entire stabilizing plate 4, and then flow into the tank body 1 below the stabilizing plate 4 at a certain speed through the diversion hole 5 of the stabilizing plate 4.

[0031] In one embodiment, the water guide holes 5 are radially distributed on the stabilizing plate 4 with the closed area 41 as the center. The water guide holes 5 are radially distributed from the inside to the outside of the stabilizing plate 4 with the closed area 41 as the center, which conforms to the law that the incoming water diffuses from the inside to the outside of the stabilizing plate.

[0032] Specifically, Figure 3 As shown, a plurality of guide hole layers 42 are evenly distributed around the closed area 41, the plurality of guide hole layers 42 are coaxially arranged, the guide hole layer 42 includes a plurality of guide holes 5, and the intervals between adjacent guide holes 5 in the guide hole layer 42 are equal. The coaxial arrangement in this embodiment specifically refers to that the connecting lines of the centers of the guide holes 5 in each guide hole layer 42 form a figure that is coaxially arranged.

[0033] Furthermore, the tank body 1 is a cylinder, and the corresponding stabilizing plate 4 is a circle, whose size matches the inner diameter of the tank body 1, the water inlet 2 is located at the center of the top of the tank body, the closed area 41 is located in the middle of the stabilizing plate 4, and the guide hole layer 42 is distributed in concentric circles. Specifically, the lines connecting the centers of the guide holes 5 in each guide hole layer 42 form a circle, and these circles are concentric circles. Furthermore, the number of guide holes 5 in each guide hole layer 42 is equal, and the guide holes 5 from the inside to the outside are distributed in a radial manner. In this embodiment, the number of guide holes 5 in each guide hole layer 42 is 24. The tank body 1 adopts a cylindrical structure to facilitate production and manufacturing.

[0034] In one embodiment, the diameter of the water guide hole 5 located on the inner side of the stabilizing plate 4 is smaller than the diameter of the water guide hole 5 located on the outer side of the stabilizing plate 4. Considering that the water inlet 2 is located in the middle of the top of the tank body 1, that is, the incoming water diffuses from the middle of the stabilizing plate 4 to the outside, the incoming water will preferentially flow downward from the water guide hole 5 near the inner side of the stabilizing plate 4, so the aperture size of the inner guide hole 5 is made smaller than the aperture size of the outer guide hole 5, thereby keeping the flow rate of the inner and outer water guide holes 5 consistent.

[0035] Specifically, there are 7 guide hole layers 42, and from the inside to the outside of the stabilizing plate 4, the diameters of the guide holes in the 7 guide hole layers 42 are 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, and 4.5 mm, respectively. This size design can effectively keep the water inlet flow rate of the inner and outer water guide holes 5 stable and consistent.

[0036] In one embodiment, the water outlet 3 is connected to a water outlet pipeline (not shown), and the inlet of the water outlet pipeline is located at the bottom of the tank body 1. After the water inlet 2 is opened, the normal temperature water quickly diffuses to the upper part of the entire stabilizing plate 4, and then enters the tank body 1 synchronously at a certain speed through the diversion hole 5, forming a water inlet layer at the top of the water body, and the water inside the tank body 1 is discharged from the water outlet 3 through the water outlet pipeline at the bottom position, and the water level inside the tank body 1 will gradually drop under the pressure of the water inlet layer, so that the cooling water and the inlet water have a stable contact surface and drop at a set speed, thereby achieving the purpose of cooling water out first.

[0037] In one embodiment, the tank body 1 is provided with a temperature detection port 6, and the temperature detection port 6 is used to install a temperature sensor to detect the temperature of the liquid inside the tank body 1. In addition, a water level detection and air passage port 7 is also provided on the top of the tank body 1.

[0038] The tank body 1 is divided into two parts, the upper part is a stabilizing plate 4, the stabilizing plate 4 and the tank body are an integrated structure, a tank cover 11 is arranged above the stabilizing plate 4, the tank cover 11 is fixedly connected to the stabilizing plate 4, a water inlet 2 is arranged in the middle of the tank cover 11, a water outlet 3 is arranged on each side, and a temperature detection port 6 is also arranged on the tank cover 11. Figure 4 As shown, the lower part of the tank body 1 is divided into two layers, the upper layer is a water storage layer 12 for storing water, and the lower layer is a separation layer 13 for placing refrigeration related components.

[0039] The utility model also provides a beverage equipment embodiment, including the above-mentioned cold water tank embodiment, and the beverage equipment can specifically be beverage preparation equipment such as a coffee machine, a water dispenser, etc.

[0040] In summary, the cold water tank embodiment provided in this embodiment provides a stabilizing plate at the water inlet of the tank body, so that the incoming water first contacts the stabilizing plate after entering the tank body, thereby preventing the incoming water from directly contacting and mixing with the cooling water in the tank body. The incoming water covers the surface of the stabilizing plate, then flows to the bottom of the stabilizing plate through the water guide holes evenly distributed on the stabilizing plate, and finally mixes with the cooling water below. The guide holes allow the incoming water to flow synchronously to the bottom of the stabilizing plate at a certain speed, so that the incoming water and the cooling water maintain a stable contact surface, greatly reducing the disturbance degree when the incoming water and the cooling water are mixed, thereby reducing the impact on the outlet water temperature.
