Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a cold storage box structure controlled by pressure feedback. Background Art

[0002] In the drinking water system, not only hot water and room temperature water are needed, but now even ice water is needed. Therefore, a cold storage tank is used in the drinking water system. The water is cooled by the cold storage tank. By transporting the water to the inside of the cold storage tank and cooling the water with a refrigerant medium, the appropriate water temperature can be selected for drinking according to actual usage to meet the needs.

[0003] Traditionally, the temperature control of drinking water systems mainly relies on the sensing and control of water temperature by temperature sensors. However, the specific conditions of the freezing state of the refrigerant medium are not clear when using temperature sensors, that is, the freezing state of the medium water by the refrigerant is not clear. After freezing, it is not 0 degrees, and the amount of ice cannot be accurately sensed. Since the amount of ice has a great influence on the cooling efficiency of the water channel, the degree of cooling cannot be accurately controlled by the temperature sensor. Therefore, we propose a cold storage box structure controlled by pressure feedback to solve the above problems. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model.

[0025] Example

[0026] Reference Figure 1-Figure 5 The utility model provides a technical solution: a cold storage box structure controlled by pressure feedback, including a box body 1 and a pressure feedback mechanism 3, a vacuum chamber 2 is installed inside the box body 1, the pressure feedback mechanism 3 includes a pressure sensor 31, the pressure sensor 31 is installed inside the vacuum chamber 2, a push plate 32 is arranged inside the vacuum chamber 2 and is slidably connected to the inner wall of the vacuum chamber 2, a connecting rod 331 is fixedly and rotatably installed on one side of the push plate 32, and a connecting plate 33 is fixedly installed on one end of the connecting rod 331.

[0027] In a preferred embodiment, a rubber sealing plate 4 is fixedly installed on the upper end of the interior of the box body 1, and the connecting plate 33 is fixedly installed on the rubber sealing plate 4 to isolate the vacuum chamber 2. In order to prevent the liquid inside the box body 1 from entering the interior of the vacuum chamber 2, the rubber sealing plate 4 is fixedly installed at a position between the interior of the box body 1 and the vacuum chamber 2, so that the vacuum chamber 2 is always in a vacuum state to meet the requirements of use.

[0028] In a preferred embodiment, a raw water inlet pipe 5 and a refrigerant pipe 6 are installed inside the box body 1, and the inlet of the raw water inlet pipe 5 and the inlet of the refrigerant pipe 6 are arranged to be opposite, and the middle sections of the raw water inlet pipe 5 and the refrigerant pipe 6 are arranged in an S shape inside the box body 1. In order to facilitate heat exchange of water through the refrigerant medium, the middle sections of the raw water inlet pipe 5 and the refrigerant pipe 6 are both arranged in an S shape, which extends the liquid flow distance and improves the heat exchange effect of the liquid inside the raw water inlet pipe 5 to meet the usage requirements.

[0029] In a preferred embodiment, the pressure sensor 31 is electrically connected to the PLC controller 7, the PLC controller 7 is electrically connected to the compressor 8, the inlet end of the compressor 8 is fixedly connected to the outlet end of the refrigerant pipe 6, and the compressor 8 in the present device is automatically controlled to start and stop according to the pressure intensity received by the pressure sensor 31. When the pressure received by the pressure sensor 31 increases, the compressor 8 will work normally. On the contrary, when the pressure received by the pressure sensor 31 is small or there is no pressure, the compressor 8 stops working, thereby controlling the delivery speed of the refrigerant.

[0030] The device presses the pressure sensor 31 through the push plate 32, and determines the amount of ice by the pressure applied to the pressure sensor 31. Therefore, a sliding groove 9 is provided on the inner top of the box body 1, and a slider 10 is provided inside the sliding groove 9. The slider 10 is fixedly connected to the push plate 32. The push plate 32 is fixedly connected to the slider 10, so that the push plate 32 can move stably inside the vacuum chamber 2, thereby squeezing the pressure sensor 31 to meet the use requirements.

[0031] The pressure is detected by the pressure sensor 31. In order to facilitate personnel to timely understand the amount of ice inside the box 1, the pressure sensor 31 is electrically connected to the display 11. The display 11 is installed on the outer surface of the box 1. The support frame 12 is installed on the outer surface of the box 1, and the display 11 is fixedly installed on the support frame 12. Therefore, two pressure sensors 31 are set and are respectively set on the left and right sides of the vacuum chamber 2. The position of the push plate 32 corresponds to the position of the pressure sensor 31. After the pressure sensor 31 detects the pressure, it will transmit the pressure value to the display 11, so that the staff can observe the value on the display 11. The larger the value, the more ice is formed.

[0032] When the box body 1 is in use, a large amount of water will be injected into the interior of the box body 1. Through the freezing of water, the liquid inside the raw water inlet pipe 5 can be quickly cooled and cooled, so that the discharged water is ice water to meet people's needs. However, the liquid inside the box body 1 needs to be replaced regularly, so an inlet pipe 13 is installed on the outer surface of one side of the box body 1, and a discharge pipe 14 is installed on the outer surface of the other side of the box body 1. Control valves 15 are installed on the inlet pipe 13 and the discharge pipe 14. Through the inlet pipe 13 and the discharge pipe 14, the liquid inside the box body 1 can be conveniently replaced to keep the water clean and meet the use requirements.

[0033] Specifically, the working process or working principle of a cold storage box structure controlled by pressure feedback is as follows: Traditionally, the temperature control of the drinking water system mainly relies on the sensing and control of the water temperature by the temperature sensor. However, the specific conditions of the freezing state of the refrigerant medium using the temperature sensor are not clear, that is, the freezing state of the medium water by the refrigerant is not clear. After freezing, it is not 0 degrees, and the amount of ice cannot be accurately sensed. Since the amount of ice has a great influence on the cooling efficiency of the water channel, the degree of cooling cannot be accurately controlled by the temperature sensor. Therefore, this device is designed to solve this problem. This device is connected to a large-scale drinking water device outside and used. The drinking water device can not only release hot water, but also release cold water to meet the needs of different groups of people.

[0034] The raw water inlet pipe 5 on the box 1 is connected to the external drinking water equipment, and the refrigerant pipe 6 is connected to the external medium adding equipment, and the external power supply is connected. If cold water is needed, the normal temperature water stored in the external drinking water equipment is moved into the raw water inlet pipe 5, and continuously flows in the raw water inlet pipe 5 and enters the box 1. At the same time, the refrigerant medium is transported to the refrigerant pipe 6, and the box 1 is filled with water. The normal temperature water flows in the raw water inlet pipe 5, and the refrigerant flows in the refrigerant pipe 6. The refrigerant will exchange heat with the normal temperature water in the raw water inlet pipe 5 to reduce the temperature of the normal temperature water. At the same time, the refrigerant will also cool the water in the box 1 and cool the water in the box 1 to a state where it can be frozen.

[0035] As the water inside the box body 1 continues to freeze, its volume will increase after freezing, which will squeeze the rubber sealing plate 4, thereby pushing the connecting plate 33 to move. The connecting rod 331 rotatably installed on the connecting plate 33 will rotate, thereby controlling the movement of the pushing plate 32, squeezing the pushing plate 32 against the pressure sensor 31, and displaying the pressure generated by the pressure sensor 31 on the display 11, so that the staff can observe the freezing situation. The more ice there is inside the box body 1, the greater the squeezing effect on the rubber sealing plate 4, thereby increasing the squeezing force on the pressure sensor 31. The staff can obtain the freezing situation inside the box body 1 by observing the pressure value, thereby obtaining the heat exchange efficiency to meet the use requirements.

[0036] In order to prevent the raw water inlet pipe 5 from freezing, the device can circulate the water inside the raw water inlet pipe 5 when in standby mode, and the refrigerant pipe 6 is made of copper pipe material and the raw water inlet pipe 5 is made of 304 stainless steel.

[0037] It should be noted that the pressure sensor 31, PLC controller 7, compressor 8 and display 11 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
