Description

Technical Field

[0001] The invention belongs to the technical field of air source heat pumps, in particular to a defrosting device for an air source heat pump unit. Background Art

[0002] An air source heat pump unit is a unit that absorbs heat from the ambient heat energy in the air through an evaporator, thereby evaporating the heat transfer medium, and through a series of thermodynamic cycle processes, transfers the absorbed heat to the water or air that needs to be heated, thereby achieving cooling or heating functions. When the air source heat pump unit is used at a lower temperature, frost will form on the external surface of the heat exchanger. The presence of the frost layer will hinder the transfer of heat, resulting in the heat exchanger being unable to perform normal heat exchange, thereby affecting the heating effect and operating efficiency of the unit. Therefore, defrosting can ensure that the unit can still operate normally in a low temperature environment and provide a stable heating effect.

[0003] The patent with announcement number CN219531343U discloses a defrosting device for an air source heat pump unit, and relates to the technical field of air source heat pumps. The patent includes a sliding assembly; wherein the sliding assembly includes an annular slide fixedly connected to the outer end of a connecting plate, a slide connected to the middle side of the upper surface of the right end of the annular slide for sliding connection, a drive motor fixedly connected to the upper end of the slide, a lead screw connected to the upper end of the drive motor, and a bearing connected to the top of the lead screw for rotation; the outer periphery of the middle end of the lead screw surrounds a connecting nut, a movable plate fixedly connected to the rear end of the nut, a movable plate movably connected to a guide rail at the rear end of the movable plate, and a mounting plate fixedly connected to the upper end of the guide rail. By setting a sliding assembly, the patent solves the problem that the current defrosting device can usually only defrost the main parts of the surface of the air source heat pump when working, and the defrosting device is usually a fixed structure. Due to the large area of ​​the heat exchanger, the traditional defrosting device is not convenient for all-round defrosting.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although defrosting is achieved by setting a fan that can move around the unit to blow hot air onto the surface of the unit, when the frost layer melts, water will be formed and flow downward with the unit, thereby accumulating at the bottom of the unit. When water accumulates at the bottom of the unit for a long time, it may cause rust or corrosion of metal parts at the bottom of the unit, affecting the overall structure and durability of the unit. Moreover, when water accumulates at the bottom of the unit, the water flow may penetrate into the interior of the unit through the tiny gaps at the bottom of the unit, affecting the electrical components inside the unit.

[0021] 2. The defrosting device for an air source heat pump unit described in the present invention utilizes an adjustable centralized discharge collection mechanism to enable collection box one and collection box two to fit the four sides of the unit. When frost on the surface of the heat exchanger melts into water and flows downward, it will flow into collection box one and collection box two, thereby realizing the collection of water flow, avoiding the situation where water flows to the bottom of the unit and accumulates at the bottom of the unit, causing rust or corrosion of metal parts at the bottom of the unit, affecting the overall structure and durability of the unit, and at the same time, it also avoids the situation where water flows to the bottom of the unit and penetrates into the inside of the unit through the tiny gaps at the bottom of the unit, affecting the internal electrical components of the unit, and the water in collection box one will flow to collection box two on the right side along hose one, while the water in collection box two on the left side will flow to collection box two on the right side through hose two, and finally, can be discharged uniformly through the drain pipe, and the water in collection box one and collection box two can be contained by placing a collection container at the drain pipe, or by connecting the drain pipe with other pipes. The water in the collecting box 1 and the collecting box 2 is connected, thereby realizing the transfer of the water flow in the collecting box 1 and the collecting box 2, avoiding the situation that the water volume in the collecting box 1 and the collecting box 2 gradually increases and flows to the unit again. At the same time, with the cooperation of the hose 1 and the hose 2, all the water flows can be gathered in the collecting box 2 on the right and discharged from the same position for easy collection.

[0037] Specifically, when it is necessary to defrost the surface of the outdoor heat exchanger of the air source heat pump unit, the fan 8 is turned on and the electric heating coil 10 is energized for heating. Since the electric heating coil 10 is close to the unit, the frost on the surface of the heat exchanger can be defrosted. At the same time, since the electric heating coil 10 is arranged at the air outlet of the fan 8, the wind blown by the fan 8 will also be blown to the surface of the heat exchanger after heating, further improving the defrosting effect.

[0038] In this embodiment, Figure 1-Figure 3 , Figure 5-Figure 8 As shown, a threaded rod 2 6 is rotatably provided on one side of the collecting box 17 , and the threaded rod 2 6 is threadedly connected to the base 1 .

[0040] One side of the collecting box 17 is slidably connected to two sliding rods 5 31 , and one end of the sliding rod 5 31 is fixedly connected to a tooth plate 21 , on which a plurality of teeth are arranged.

[0041] One end of the slide bar 5 31 is fixedly connected to the extrusion block 2 33, one side of the collection box 17 is rotatably provided with an eccentric block 24, one side of the collection box 17 is fixedly connected to the motor 3 23, the output end of the motor 3 23 is fixedly connected to the eccentric block 24, one side of the slide bar 5 31 is sleeved with a spring 9, one end of the spring 9 is fixedly connected to the extrusion block 2 33, and the other end of the spring 9 is fixedly connected to one side of the collection box 17.

[0042] Two slide bars 4 28 are slidably connected to one side of the collecting box 2 18 , and one end of the slide bar 4 28 is fixedly connected to a tooth plate 1 20 , on which a plurality of teeth are arranged.

[0043] One end of the slide rod 4 28 is fixedly connected to the extrusion block 1 27 , and one side of the slide rod 4 28 is sleeved with a spring 29 , one end of the spring 29 is fixedly connected to one side of the extrusion block 1 27 , and the other end of the spring 29 is fixedly connected to one side of the collection box 2 18 .

[0044] An eccentric block 25 is rotatably provided on one side of the collecting box 18 , and a motor 4 26 is fixedly connected to one side of the collecting box 18 , and an output end of the motor 4 26 is fixedly connected to the eccentric block 25 .

[0045] Specifically, the defrosting device of the existing air source heat pump unit, when in use, is provided with a fan 8 that can move around the unit to blow hot air to the surface of the unit to achieve defrosting. However, when the frost layer melts, water will be formed and flow downward with the unit, thereby accumulating at the bottom of the unit. When water accumulates at the bottom of the unit for a long time, it may cause the metal parts at the bottom of the unit to rust or corrode, affecting the overall structure and durability of the unit. Moreover, when there is water accumulation at the bottom of the unit, the water flow may penetrate into the inside of the unit through the tiny gaps at the bottom of the unit, affecting the electrical components inside the unit.

[0046] Therefore, in order to solve the above problems, when using this embodiment, the base 1 is sleeved on the outside of the unit, and the base 1 does not contact the unit, and the unit is in the middle of the base 1. According to the size of the unit, the threaded rod 1 4 and the threaded rod 2 6 are manually rotated to make the collection box 1 17 and the collection box 2 18 move at the same time and approach the surface of the unit until they fit the surface of the unit. The position of the collection box 1 17 and the collection box 2 18 can be adjusted according to the size of the unit, and the versatility is strong.

[0047] When the frost on the surface of the heat exchanger melts into water and flows downward, it will flow into the collecting box 1 17 and the collecting box 2 18, thereby realizing the collection of the water flow, avoiding the situation that the water flows to the bottom of the unit and accumulates at the bottom of the unit, causing the metal parts at the bottom of the unit to rust or corrode, affecting the overall structure and durability of the unit, and at the same time, avoiding the situation that the water flows to the bottom of the unit and penetrates into the inside of the unit through the tiny gaps at the bottom of the unit, causing the electrical components inside the unit to be affected;

[0048] Since the water flows into the two collection boxes 1 17 and the two collection boxes 2 18, the amount of water in the collection boxes 1 17 and the collection boxes 2 18 will gradually increase. When the water overflows from the collection boxes 1 17 and the collection boxes 2 18, it will flow to the unit. When a drainage port is set in each collection box 1 17 and the collection box 1 17, the water discharge position will be too dispersed, which is not conducive to collection. Therefore, in order to solve this problem, the water in the collection box 1 17 will flow to the collection box 2 18 on the right side along the hose 1 22, and the water in the collection box 2 18 on the left side will flow to the collection box 1 on the right side through the hose 2 30. The water in the collecting box 17 and the collecting box 18 can finally be uniformly discharged through the drain pipe 19, and the water in the collecting box 17 and the collecting box 18 can be collected by placing a collecting container at the drain pipe 19 or connecting the drain pipe 19 with other pipes, thereby realizing the transfer of the water in the collecting box 17 and the collecting box 18, avoiding the situation that the water in the collecting box 17 and the collecting box 18 gradually increases and flows to the unit again. At the same time, with the cooperation of the hose 1 22 and the hose 2 30, all the water flows can be gathered in the collecting box 18 on the right side and discharged from the same position for easy collection;

[0049] Since frosting occurs when the outdoor temperature is low, when frost forms on the surface of the unit, ice may also form. When an ice layer forms on the surface of the unit, although the ice layer can be melted into water by electric heating, some ice cubes may not be completely melted and fall into the collection box 17 and the collection box 2 18. When the ice cubes are in the collection box 17 and the collection box 2 18, they will hinder the flow of water, thereby affecting the discharge of water. Therefore, in order to avoid this problem, when defrosting, the motor 3 23 and the motor 4 26 are started at the same time, and the motor 3 23 and the motor 4 26 respectively drive the eccentric block 1 24 and the eccentric block 2 25 to rotate, and the eccentric block 1 24 and the eccentric block 2 25 respectively squeeze the extrusion block 2 33 and the extrusion block 1 27, so that the slide bar 5 31 and the slide bar 4 28 slide, and under the action of the spring 1 9 and the spring 2 29 By restoring the tooth plate 1 20 and the tooth plate 2 21, a lateral reciprocating movement can be formed to break the ice cubes in the collection box 1 17 and the collection box 2 18 and disperse them, thereby avoiding the situation where the ice cubes fall into the collection box 1 17 and the collection box 2 18 and hinder the flow of water, thereby ensuring the normal discharge of water. In addition, since the unit is used outdoors, not only ice cubes, but also leaves and other impurities may be attached to its surface. After these impurities fall into the collection box 1 17 and the collection box 2 18 with the water flow, they may block the collection box 1 17 and the collection box 2 18, thereby affecting the flow of water. When the tooth plate 1 20 and the tooth plate 2 21 are in motion, these impurities can be moved, thereby avoiding the situation where the impurities are blocked in the collection box 1 17 and the collection box 2 18 and affect the flow of water, thereby further ensuring the normal discharge of water.

[0050] Working principle: The base 1 is sleeved on the outside of the unit, and the base 1 does not contact the unit. The unit is in the middle of the base 1. According to the size of the unit, manually rotate the threaded rod 1 4 and the threaded rod 2 6 to move the collection box 1 17 and the collection box 2 18 at the same time and approach the surface of the unit until they fit the surface of the unit. The position of the collection box 17 and the collection box 2 18 can be adjusted according to the size of the unit, and the versatility is strong. When it is necessary to defrost the surface of the outdoor heat exchanger of the air source heat pump unit, turn on the fan 8 and energize the electric heating coil 10 for heating. Since the electric heating coil 10 is close to the unit, the frost on the surface of the heat exchanger can be defrosted. At the same time, due to the electric heating The coil 10 is arranged at the air outlet of the fan 8, so the air blown by the fan 8 will also be blown to the surface of the heat exchanger after being heated, further improving the defrosting effect, and the motor 13 can drive the threaded rod 3 11 to rotate, and the motor 2 14 can drive the gear 15 to rotate, so that the fan 8 can be raised and lowered and make a circular motion, thereby expanding the heating range and making the frost on the surface of the heat exchanger be evenly removed; when the frost on the surface of the heat exchanger melts into water and flows downward, it will flow into the collection box 1 17 and the collection box 2 18, thereby realizing the collection of the water flow, avoiding the water flowing to the bottom of the unit and accumulating at the bottom of the unit, causing the metal parts at the bottom of the unit to rust or corrode, affecting the overall structure and durability of the unit. At the same time, it also avoids the situation that the water flows to the bottom of the unit and penetrates into the inside of the unit through the tiny gap at the bottom of the unit, affecting the internal electrical components of the unit; because the water flows to the two collecting boxes 17 and the two collecting boxes 18, the amount of water in the collecting boxes 17 and 18 will gradually increase. When the water overflows from the collecting boxes 17 and 18, it will flow to the unit again. When each collecting box 17 and each collecting box 17 are provided with a drain port, the water discharge position will be too dispersed, which is not conducive to collection. Therefore, in order to solve this problem, the water in the collecting box 17 will flow to the collecting box 2 18 on the right along the hose 1 22, and The water in the left collecting box 18 will flow to the right collecting box 18 through the hose 30, and finally, it can be uniformly discharged through the drain pipe 19. In addition, the water flows in the collecting boxes 17 and 18 can be collected by placing a collecting container at the drain pipe 19, or by connecting the drain pipe 19 with other pipes, thereby realizing the transfer of the water flows in the collecting boxes 17 and 18, avoiding the situation that the water in the collecting boxes 17 and 18 gradually increases and flows to the unit again. At the same time, with the cooperation of the hose 22 and the hose 30, all the water flows can be gathered in the right collecting box 18 and discharged from the same position, which is convenient for collection.Since frosting occurs when the outdoor temperature is low, when frost forms on the surface of the unit, ice may also form. When an ice layer forms on the surface of the unit, although the ice layer can be melted into water by electric heating, some ice cubes may not be completely melted and fall into the collection box 17 and the collection box 2 18. When the ice cubes are in the collection box 17 and the collection box 2 18, they will hinder the flow of water, thereby affecting the discharge of water. Therefore, in order to avoid this problem, when defrosting, the motor 3 23 and the motor 4 26 are started at the same time, and the motor 3 23 and the motor 4 26 respectively drive the eccentric block 1 24 and the eccentric block 2 25 to rotate, and the eccentric block 1 24 and the eccentric block 2 25 respectively squeeze the extrusion block 2 33 and the extrusion block 1 27, so that the slide bar 5 31 and the slide bar 4 28 slide, and under the action of the spring 1 9 and the spring 2 29 By restoring the tooth plate 1 20 and the tooth plate 2 21, the tooth plate 1 20 and the tooth plate 2 21 can be reciprocated horizontally to break the ice in the collection box 1 17 and the collection box 2 18 and disperse them, thereby avoiding the situation where the ice falls into the collection box 1 17 and the collection box 2 18 and hinders the flow of water, and ensures the normal discharge of water. In addition, since the unit is used outdoors, not only ice, but also impurities such as leaves may be attached to its surface. After these impurities fall into the collection box 1 17 and the collection box 2 18 with the water flow, they may block the collection box 1 17 and the collection box 2 18, thereby affecting the flow of water. When the tooth plate 1 20 and the tooth plate 2 21 are in motion, these impurities can be moved, thereby avoiding the situation where the impurities are blocked in the collection box 1 17 and the collection box 2 18 and affect the flow of water, and further ensuring the normal discharge of water. ;
