Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration-related equipment, and more specifically, to a device for filtering, circulating, and reusing the cooling water of an ice maker. Background Art

[0002] An ice maker is a refrigeration mechanical device that generates ice by cooling water through an evaporator with a refrigerant in a refrigeration system. It uses a refrigeration system with water as a carrier and manufactures ice after passing through a certain device when powered on. According to the principle of the evaporator and different production methods, the shapes of the generated ice cubes are also different; generally, ice makers are classified into pellet ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. according to the shape of the ice.

[0003] During the operation of the ice maker, since the compressor emits a large amount of heat, it is necessary to cool it down so that it can work normally. In actual use, water cooling is mostly used to cool it.

[0004] Currently, after the cooling water is used, it takes a certain amount of time to cool again. The conventional method is to directly discharge the cooling water, which will increase the consumption of the cooling water and increase the use cost of the ice maker.

[0005] Therefore, in view of this, the existing structure is studied and improved to provide a device for filtering, circulating, and reusing the cooling water of an ice maker, with the expectation of achieving a more practical value. Summary of the Invention

Cold air enters the interior of the refrigeration sealed box 1 through the cold air inlet pipe 2 to complete heat exchange and refrigeration operations.

[0073] Four cooling water heat exchange components 4 arranged side by side are provided at the upper-middle position inside the refrigeration sealed box 1. A sealing component 5 is provided between the four cooling water heat exchange components 4. An internal circulation component 6 is provided at the lower-middle position inside the refrigeration sealed box 1.

[0074] The four cooling water heat exchange components 4 can effectively increase the heat exchange area, thereby ensuring the heat exchange efficiency. The sealing component 5 is used to ensure that the part of the cooling water heat exchange component 4 in contact with cold water is in a sealed state, thereby avoiding losses caused by the outward dissipation of cold air. The internal circulation component 6 is used to return and re-cool the cooling water with insufficient cooling temperature until the cooling water meets the cooling temperature.

[0075] The refrigeration sealed box 1 includes a basic housing 101. The basic housing 101, the cooling water heat exchange component 4, and the sealing component 5 can form a cold chamber, and then cooperate with the cold air inlet pipe 2 and the cold air outlet pipe 3 to realize the circulating cooling of cold air.

[0076] One side of the basic housing 101 is bolted to an inlet end side housing 102, and the other side of the basic housing 101 is bolted to an outlet end side housing 103. Both the inlet end side housing 102 and the outlet end side housing 103 can be disassembled by bolts, which can effectively reduce the difficulty of assembling or disassembling the entire refrigeration sealed box 1.

[0077] The top ends of the basic housing 101, the inlet end side housing 102, and the outlet end side housing 103 are bolted to a top cover 104 to form the seal at the top of the refrigeration sealed box 1 by using the top cover 104.

[0078] The bottom ends of the basic housing 101, the inlet end side housing 102, and the outlet end side housing 103 are bolted to a bottom cover 105 to form the seal at the bottom of the refrigeration sealed box 1 by using the top cover 104.

[0079] The cooling water heat exchange component 4 includes a high-position L-shaped plate 401 and a low-position L-shaped plate 402. Both the high-position L-shaped plate 401 and the low-position L-shaped plate 402 are fixed to the basic housing 101 by bolts. The high-position L-shaped plate 401 and the low-position L-shaped plate 402 are arranged in parallel and face in opposite directions. By the way of bolt fixation, it is convenient for the installation or separation of the high-position L-shaped plate 401 and the low-position L-shaped plate 402 from the basic housing 101.

[0080] A multi-pass copper water pipe 403 is arranged between the high-position L-shaped plate 401 and the low-position L-shaped plate 402. The multi-pass copper water pipe 403 is in contact with the cold air to complete heat exchange.

[0081] A water pipe 404 with a valve is arranged at the bottom end of the multi-pass copper water pipe 403. When it is necessary to replace the cooling water, the cooling water in the current water circuit can be discharged through the water pipe 404 with a valve.

[0082] One end of the multi-pass copper water pipe 403 is successively provided with a first water inlet pipe 405, a second water inlet pipe 406 and a reflux water inlet pipe 407 from top to bottom. The first water inlet pipe 405, the second water inlet pipe 406 and the reflux water inlet pipe 407 all penetrate through the high-position L-shaped plate 401. The other end of the multi-pass copper water pipe 403 is successively provided with a main drain pipe 408 and a spare drain pipe 409 from top to bottom. The main drain pipe 408 and the spare drain pipe 409 all penetrate through the low-position L-shaped plate 402.

[0083] When the cooling water flows slowly, only the first water inlet pipe 405 and the main drain pipe 408 are opened to form the circulation of the cooling water. When the cooling water flows fast, the first water inlet pipe 405, the second water inlet pipe 406, the main drain pipe 408 and the spare drain pipe 409 are all opened to avoid excessive water pressure inside the multi-pass copper water pipe 403.

[0084] The main drain pipe 408 is connected with a temperature detector 410, and the temperature detector 410 is communicated with the spare drain pipe 409.

The first output port of the two-way valve 411 is fixedly connected with a main water outlet pipe 412, and the second output port of the two-way valve 411 is fixedly connected with a reflux water outlet pipe 413.

[0085] When the cooling water is cooled and discharged, the temperature detector 410 and the two-way valve 411 cooperate. The temperature detector 410 detects whether the cooling temperature meets the requirements. If it meets the requirements, the two-way valve 411 controls the cooling water to be discharged from the main water outlet pipe 412. If it does not meet the requirements, the two-way valve 411 controls the cooling water to be discharged from the reflux water outlet pipe 413 and completes the water flow cycle.

The cooling water inlet guide pipe 415 penetrates through the side shell 102 at the water inlet end and is connected with a water inlet filter 416.

[0087] The cooling water is first filtered by the water inlet filter 416, then the cooling water is introduced into the water inlet collecting water tank 414 through the guide pipe 415, and then is divided and flows into each first water inlet pipe 405 and the second water inlet pipe 406.

[0088] The water outlet ends of the four main water outlet pipes 412 are connected to a water outlet collecting water tank 417. One end of the water outlet collecting water tank 417 is fixedly connected to a cooling water outlet guide pipe 418. The cooling water outlet guide pipe 418 penetrates through the side shell 103 of the water outlet end and is connected to a water outlet filter 419.

[0089] When the cooling water is cooled and discharged, it first converges in the water outlet collecting water tank 417, then passes through the cooling water outlet guide pipe 418, is filtered in the water outlet filter 419, and is discharged. Finally, it is led back again through the cooling water inlet guide pipe 415 to complete the circulation of the cooling water.

[0090] The sealing assembly 5 includes six first sealing plates 501 and four second sealing plates 502. Three first sealing plates 501 are all arranged between two high-position L-shaped plates 401, and three first sealing plates 501 are all arranged between two low-position L-shaped plates 402. Two second sealing plates 502 are all arranged between the high-position L-shaped plate 401 and the base housing 101, and two second sealing plates 502 are all arranged between the low-position L-shaped plate 402 and the base housing 101. The joints between the first sealing plates 501, the second sealing plates 502, the high-position L-shaped plates 401, the low-position L-shaped plates 402, and the base housing 101 are all fixed by bolts. The top ends of the sides of the first sealing plates 501, the second sealing plates 502, the high-position L-shaped plates 401, and the low-position L-shaped plates 402 are connected with sealing covers 503 by bolts.

[0091] The first sealing plates 501, the second sealing plates 502, and the sealing covers 503 are all plate-shaped or lid-shaped structures with sealing rubber. The three are used in cooperation to form a sealed heat exchange space at the position of the multi-pass copper water pipe 403, thereby maximizing the heat exchange effect.

[0092] The internal circulation assembly 6 includes an internal circulation water pump 601. One end of the internal circulation water pump 601 is fixedly connected to a first return water tank 602.

One end of the second return water tank 604 is fixedly connected to four return elbow pipes 605. The return elbow pipes 605 are communicated with the return water inlet pipe 407 through flanges. The internal circulation water pump 601, the first return water tank 602, and the second return water tank 604 are all fixed on the base housing 101.

[0093] When the cooling water temperature is insufficient, except for the pipes of the return water inlet pipe 407 and the return water outlet pipe 413, close the valves of other pipes. At this time, start the internal circulation water pump 601, and the cooling water passes through the return water outlet pipe 413 and the return long pipe 603 in sequence, and completes the confluence at the first return water tank 602, then passes through the internal circulation water pump 601, the second return water tank 604, and is branched at the return elbow 605, and finally is introduced into the respective multi-path copper water pipes 403 from the return water inlet pipe 407 to complete the secondary cooling until the cooling meets the requirements.

[0094] Embodiment 2:

[0095] Based on the above Embodiment 1, a further description is made.

[0096] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 Specifically, the base housing 101 includes two side sealing plates 1011, and a folded sealing plate 1012 is fixed between the two side sealing plates 1011.

[0097] The two side sealing plates 1011 and the folded sealing plate 1012 form an integrated structure.

[0098] Specifically, a plurality of through holes 1013 for pipes to pass through are formed on both the side sealing plate 1011 and the folded sealing plate 1012, and sealing rubber pads 1014 are sleeved inside the through holes 1013.

[0099] To ensure the smooth passing of the pipes, when used in conjunction with the sealing rubber pads 1014, the sealing performance will not be damaged when the pipes pass through.

[0100] Specifically, the base housing 101, the inlet end side housing 102, and the outlet end side housing 103 form a semi-closed housing structure, and the top cover 104 is snap-fitted on the outer top of the semi-closed housing structure, and the two are fixed by bolts.

[0102] In this way, the top cover 104 and the bottom cover 105 can be used to improve the binding effect on the semi-closed housing structure, and further improve the stability of the entire refrigeration sealing box 1 after assembly.

[0103] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 9 and Figure 10, Specifically, the multi-channel copper water pipe 403 includes a water inlet collecting pipe 4031 close to the high-position L-shaped plate 401 and a water outlet collecting pipe 4033 close to the low-position L-shaped plate 402. A number of long strip heat exchange pipes 4032 are arranged between the water inlet collecting pipe 4031 and the water outlet collecting pipe 4033.

[0106] The cooling water in the water inlet collecting pipe 4031 passes through the long strip heat exchange pipes 4032 and conducts heat exchange, and then converges in the water outlet collecting pipe 4033, which is convenient for controlling the flow direction of the water flow.

[0107] Specifically, the number of the long strip heat exchange pipes 4032 is ten, and they are all inclined.

[0108] The height of the water inlet end of the long strip heat exchange pipe 4032 is higher than that of the water outlet end.

And the water pipe 404 with a valve is at the bottom end of the water outlet collecting pipe 4033, with the lowest height, and the valve is electronically controlled. When replacing the cooling water, it is convenient to drain all the cooling water in this water path from the water pipe 404 with a valve.

[0112] The opening and closing of the water paths of the main drain pipe 408 and the standby drain pipe 409 are controlled by the electromagnetic valves 4081, and then the flow direction of the water flow in the standby drain pipe 409 is controlled by the one-way valve 4091 to avoid the water flow from the main drain pipe 408 from flowing back through the standby drain pipe 409.

[0116] The cooling water outlet guide pipe 418 is connected to the water outlet filter 419 through a flange.

[0117] The installation and disassembly of the above structures can be facilitated by the flange connection method. After all the above flanges are disconnected and the corresponding bolts are removed, the corresponding high-position L-shaped plate 401, low-position L-shaped plate 402, and multi-pass copper water pipe 403 can be removed to realize the replacement of the damaged high-position L-shaped plate 401, low-position L-shaped plate 402, and multi-pass copper water pipe 403.

[0118] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 11 and Figure 12 , specifically, the first sealing plate 501 is in an I-shaped structure, and the width of the first sealing plate 501 is twice that of the second sealing plate 502.

[0119] The I-shaped structure of the first sealing plate 501 can be clamped into the gap of the high-position L-shaped plate 401 or the low-position L-shaped plate 402, thereby improving the sealing effect.

[0120] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 13 , specifically, an annular pipe 6031 is provided on the return long pipe 603, and the annular pipe 6031 is located on the side of the water pipe 404 with a valve.

[0121] The annular pipe 6031 can bypass the return water path from the position of the water pipe 404 with a valve to avoid interference.

[0122] The water pipe 404 with a valve is connected to a short threaded water pipe 4041 through a flange, and the short threaded water pipe 4041 is threadedly connected to a long threaded water pipe 4042. The long threaded water pipe 4042 penetrates through the bottom cover 105 and reaches below the bottom cover 105.

[0123] The water pipe 404 with a valve, the short threaded water pipe 4041, and the long threaded water pipe 4042 can be separated. After separation, it is convenient to take out and replace the multi-pass copper water pipe 403.

[0124] Working principle:

[0125] When the cooling water of the ice maker completes a cycle and returns to the initial position, this device is used to re-cool the cooling water.

[0126] First, the cooling water is filtered through the inlet filter 416, then enters the inlet water collecting tank 414 from the cooling water inlet conduit 415. After that, it is divided and enters the multi-path copper water pipe 403 through the first inlet pipe 405 or the second inlet pipe 406 to wait for heat exchange. At the same time, the cold air for heat exchange enters from the cold air inlet pipe 2. The cold air completes heat exchange with the cooling water in the multi-path through pipe, and then is discharged through the main drain pipe 408 or the standby drain pipe 409 and passes through the temperature detector 410.

[0127] Then, the cooling water that has completed heat exchange is detected by the temperature detector 410. At this time, the cooling water that meets the cooling requirements is controlled by the two-way valve 411 to be discharged from the main outlet pipe 412, is collected at the outlet water collecting tank 417, then passes through the cooling water outlet conduit 418, and is filtered through the outlet filter 419, and then can perform the second cycle.

[0128] However, the cooling water that does not meet the cooling requirements is controlled by the two-way valve 411 to be discharged from the return outlet pipe 413. Then the cooling water sequentially passes through the return long pipe 603 and is collected in the first return water tank 602. Then, driven by the internal circulation water pump 601, the cooling water reaches the second return water tank 604 and is divided. The divided cooling water returns to the multi-path copper water pipe 403 through the return elbow 605 and the return inlet pipe 407 for secondary heat exchange until the final cooling water meets the usage requirements.

[0129] In this way, the filtration and recycling of the cooling water in the ice maker by this device can be completed.

[0130] The multi-path copper water pipe 403 in the device is the main cooling structure. If this structure is damaged, the structure can be taken out and replaced with a new one by removing the bolts connecting to this structure, ultimately ensuring the heat exchange effect.

[0131] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
