Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a convenient chiller unit with automatic water replenishment and drainage functions. Background Technology

[0002] In the refrigeration industry, refrigeration units are divided into evaporative refrigeration units, air-cooled chillers, and water-cooled chillers. In terms of temperature control, they are divided into low-temperature industrial chillers and normal-temperature chillers. The temperature of normal-temperature units is generally controlled within the range of 0-35 degrees Celsius, while the temperature of low-temperature units is generally controlled within the range of 0-100 degrees Celsius. Dry air energy evaporative refrigeration technology is already a very mature technology.

[0003] A search of existing Chinese patent technology, "An Evaporative Cooling Chiller Unit" (publication number CN210568985U), reveals that when the second spring is taut, it pulls the second magnet away from the first magnet. Then, the push rod also releases the crank rod. Under the force of the first spring, the crank rod resets, causing the blocking plate to block the water outlet again, thus creating a continuous cycle. Whenever the water level in the chilled water tank decreases, the storage tank automatically adds water, making it easy to replenish the chilled water tank. However, during long-term use, the two magnets will collide when they attract and come into contact with each other. With frequent collisions, the magnets will gradually lose their magnetism, thus affecting the water replenishment effect. Utility Model Content

[0004] Therefore, it is necessary to provide a convenient chiller unit with automatic water replenishment and drainage functions to address the problem that when two magnets attract and come into contact with each other during long-term use, they will collide. With frequent collisions, the magnets will gradually lose their magnetism, which will affect the water replenishment effect.

[0005] A convenient chiller unit with automatic water replenishment and drainage functions is provided, comprising: a chiller body, a base installed at the lower end of the chiller body, two chilled water pipes connected to one side of the chiller body, and a drain pipe connected to the other side of the chiller body; a liquid filling mechanism connected to one side of the chiller body; wherein, the liquid filling mechanism includes a water tank connected to one side of the chiller body, the water tank communicating with an adjacent chilled water pipe, a water pump installed on the surface of the water tank near the chiller body, a replenishment component installed at the upper end of the water tank, multiple water replenishment components disposed on the surface of the replenishment component, the lower end of the water replenishment component extending into the interior of the water tank, and the multiple water replenishment components being evenly distributed in a spiral shape along the surface of the replenishment component.

[0006] In one embodiment, the water replenishment component includes two water pipes. The upper water pipe is fixedly connected to the surface of the replenishment component, and the lower water pipe is fixedly connected to the surface of the water tank. A connecting straight pipe is provided between the two water pipes, and a connector is fixedly connected to the end of the connecting straight pipe. The connector is fixedly connected to the end of the adjacent water pipe.

[0007] In one embodiment, the replenishment component includes a replenishment box fixedly connected to the upper end of the water tank. An upper circular tube is fixedly connected to the inner top wall of the replenishment box. An internal rod is provided inside the upper circular tube. An annular airbag is fixedly connected to the surface of the internal rod near the inner bottom wall of the replenishment box. The annular airbag is slidably connected to the inner wall of the upper circular tube.

[0008] In one embodiment, the connector has a cross-shaped groove on its surface near the adjacent water pipe, and the cross-shaped groove is connected to the adjacent water pipe.

[0009] In one embodiment, a plurality of grid plates are fixedly connected to the inner wall of the connecting straight pipe, and the plurality of grid plates are evenly distributed in a ring shape along the inner wall of the connecting straight pipe.

[0010] In one embodiment, a floating ball is disposed inside the connecting straight pipe, and the surface of the floating ball is in contact with the inner wall of the upper connector.

[0011] In one embodiment, an external water pipe is fixedly connected to the top wall of the replenishment tank, the surface of the external water pipe extends to the top of the replenishment tank, and a structure in which a solenoid valve is embedded is installed on the surface of the external water pipe.

[0012] In one embodiment, the lower end of the internal rod is provided with a micro switch that is fixedly connected to the bottom wall of the replenishment box, and the micro switch is covered with a soft rubber waterproof sleeve.

[0013] Beneficial effects

[0014] 1. The above-mentioned convenient water chiller unit with automatic water replenishment and drainage functions uses a floating ball installed inside the connecting straight pipe to abut against the inner wall of the upper connector under the action of buoyancy, thereby blocking the cross groove. The liquid level inside the water tank gradually decreases. When the liquid level drops to the adjacent lower water guide pipe, the liquid inside the connecting straight pipe is injected into the water tank through the water guide pipe, maintaining the automatic replenishment of the liquid level inside the water tank and ensuring the water flow replenishment effect for long-term use.

[0015] 2. The replenishment tank stores the replenishment liquid. As the liquid inside the replenishment tank is gradually guided into the water tank, the annular air bladder inside the upper round tube moves the internal rod downwards. When the lower end of the internal rod touches the upper end of the micro switch, the controller opens the solenoid valve to introduce external water flow into the replenishment tank, ensuring the water replenishment effect for long-term use.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a convenient water chiller unit with automatic water replenishment and drainage functions.

[0026] In one embodiment, a convenient chiller unit with automatic water replenishment and drainage functions includes: a chiller body 1, a base 2 installed at the lower end of the chiller body 1, two chilled water pipes connected to one side of the chiller body 1, and a drain pipe connected to the other side of the chiller body 1; and a liquid filling mechanism 3 connected to one side of the chiller body 1.

[0027] The liquid filling mechanism 3 includes a water tank 31 connected to one side of the chiller body 1. The water tank 31 is connected to an adjacent chilled water pipe. A water pump 311 is installed on the surface of the water tank 31 near the chiller body 1. A replenishment component 33 is installed at the upper end of the water tank 31. Multiple water replenishment components 32 are provided on the surface of the replenishment component 33. The lower end of the water replenishment component 32 extends into the interior of the water tank 31. The multiple water replenishment components 32 are evenly distributed in a spiral shape along the surface of the replenishment component 33.

[0028] It should be noted that: a controller is installed inside the base 2, wherein the output terminal of the micro switch 336 is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the input terminal of the solenoid valve 338. The solenoid valve 338 is normally closed. When the micro switch 336 is pressed by the internal rod 334, it transmits a signal to the controller, and the controller causes the solenoid valve 338 to open.

[0029] like Figure 1-4 As shown, the water replenishment component 32 includes two water pipes 321. The upper water pipe 321 is fixedly connected to the surface of the replenishment component 33, and the lower water pipe 321 is fixedly connected to the surface of the water tank 31. A connecting straight pipe 323 is provided between the two water pipes 321. A connector 322 is fixedly connected to the end of the connecting straight pipe 323. The connector 322 is fixedly connected to the end of the adjacent water pipe 321.

[0030] A cross-shaped through groove 325 is provided on the surface of the connector 322 near the adjacent water pipe 321. The cross-shaped through groove 325 is connected to the adjacent water pipe 321. Multiple grid plates 324 are fixedly connected to the inner wall of the connecting straight pipe 323. The multiple grid plates 324 are evenly distributed in a ring shape along the inner wall of the connecting straight pipe 323. A floating ball 326 is provided inside the connecting straight pipe 323. The surface of the floating ball 326 is in contact with the inner wall of the upper connector 322.

[0031] In this embodiment, under normal conditions, the liquid level inside the water tank 31 is above the lower water guide pipe 321. Due to the floating ball 326 installed inside the connecting straight pipe 323, it abuts against the inner wall of the upper connector 322 under the action of buoyancy, thereby blocking the cross groove 325. The liquid level inside the water tank 31 gradually decreases. When the liquid level drops to the adjacent lower water guide pipe 321, the liquid inside the connecting straight pipe 323 is injected into the water tank 31 through the water guide pipe 321, maintaining the effect of automatic replenishment of the liquid level inside the water tank 31.

[0032] Furthermore, when the liquid is directed into the water tank 31 at the flow port of the upper water pipe 321, the floating ball 326 is always above the liquid surface. When the cross groove 325 is located on the inner wall of the lower connector 322 and the lower cross groove 325 is blocked, the lower water pipe 321 and the water tank 31 form a relatively closed effect.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the replenishment component 33 includes a replenishment box 331 fixedly connected to the upper end of the water tank 31. An upper circular tube 332 is fixedly connected to the inner top wall of the replenishment box 331. An inner rod 334 is provided inside the upper circular tube 332. An annular airbag 333 is fixedly connected to the surface of the inner rod 334 near the inner bottom wall of the replenishment box 331. The annular airbag 333 is slidably connected to the inner wall of the upper circular tube 332.

[0034] An external water pipe 337 is fixedly connected to the inner top wall of the replenishment box 331. The surface of the external water pipe 337 extends to the top of the replenishment box 331. A solenoid valve 338 is embedded in the surface of the external water pipe 337. A micro switch 336 is fixedly connected to the inner bottom wall of the replenishment box 331 at the lower end of the internal rod 334. A soft rubber waterproof sleeve 335 is fitted over the micro switch 336.

[0035] In this embodiment, the device stores replenishment liquid through a replenishment tank 331. As the liquid inside the replenishment tank 331 is gradually guided into the water tank 31, the annular airbag 333 inside the upper circular tube 332 causes the internal rod 334 to move downward. When the lower end of the internal rod 334 abuts against the upper end of the micro switch 336, the controller opens the solenoid valve 338 to introduce external water flow into the replenishment tank 331.

[0036] Working principle: The liquid is guided into the water tank 31 at the flow port of the upper water pipe 321. The floating ball 326 is always above the liquid surface. The cross groove 325 is located on the inner wall of the lower connector 322 and blocks the lower cross groove 325. Under normal conditions, the liquid level inside the water tank 31 is above the lower water pipe 321. The floating ball 326 in the connecting straight pipe 323 and the inner wall of the upper connector 322 block the cross groove 325. The liquid level inside the water tank 31 gradually decreases until the liquid level drops to the adjacent lower water pipe 321. The liquid inside the connecting straight pipe 323 is injected into the water tank 31 through the water pipe 321, keeping the liquid level inside the water tank 31 automatically replenished.

[0037] It should be noted that the micro switch 336, solenoid valve 338, and controller mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the micro switch 336, solenoid valve 338, and controller can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
