Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment with refrigeration and cold storage functions. Background Art

[0002] The refrigeration principle of a general refrigerator is that the function of the compressor is to compress the steam with lower pressure into steam with higher pressure, so that the volume of the steam decreases and the pressure increases. The compressor inhales the working fluid steam with lower pressure from the evaporator, increases its pressure and then sends it to the condenser, where it condenses into a liquid with higher pressure. After being throttled by the throttle valve, it becomes a liquid with lower pressure and then is sent to the evaporator, where it absorbs heat and evaporates to become steam with lower pressure, which is then sent to the inlet of the compressor, thus completing the refrigeration cycle.

[0003] When existing refrigeration equipment is in cooling mode for a long time, the surface temperature of the evaporator is low, and water vapor in the environment adheres to the surface of the evaporator and frost occurs. When the amount of frost is large, it will affect the heat exchange efficiency and seriously reduce the cooling effect.

[0004] Therefore, a refrigeration device with refrigeration and cold storage functions is proposed. Summary of the invention

[0005] The object of the present invention is to provide a refrigeration device with refrigeration and cold storage functions to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a refrigeration device with refrigeration and cold storage functions, comprising:

[0007] An evaporator, a first connecting pipe, a condenser and a throttle valve, wherein the evaporator, the condenser and the throttle valve are connected to each other through the first connecting pipe;

[0008] a second connecting pipe and a compressor, wherein the compressor is connected to the evaporator through the second connecting pipe;

[0009] and a defrost mechanism;

[0010] A defrosting mechanism capable of removing frost from the surface of the evaporator is arranged on the front side of the outer surface of the evaporator.

[0011] When working, the existing refrigeration equipment will have frost on the evaporator surface during the long-term refrigeration process. When the frost layer is thick, it will affect the heat exchange efficiency of the evaporator, resulting in a serious reduction in the refrigeration effect. By setting up a defrost mechanism, the frost layer on the evaporator surface can be scraped off to prevent the frost layer from affecting the evaporator efficiency and improve the refrigeration effect.

[0012] Preferably, the defrosting mechanism comprises a fixed plate, a ball seat, a movable plate, a tooth plate, a screw rod, a stepping motor, a gear, a rotating column, a thorn column, a longitudinal slide groove, a connecting column and a transverse slide groove;

[0013] The front side of the outer surface of the evaporator is symmetrically fixedly connected with a fixing plate, and a screw rod is rotatably installed on the top of the two fixing plates. The left end of the outer surface of the screw rod penetrates the fixing plate and is fixedly installed with a stepping motor, and a ball seat is rollingly installed on the outer surface of the screw rod, and the outer surface of the ball seat is slidably connected with the movable plate by setting a moving mechanism. The upper and lower surfaces of the movable plate are rotatably installed with connecting columns, and the outer surface of the connecting column located above is fixedly sleeved with a gear, and the upper surface of the movable plate is provided with a horizontal slide groove, and a tooth plate is slidably installed inside the horizontal slide groove, and the outer surfaces of the two fixed plates are symmetrically provided with longitudinal slide grooves, and the two sides of the tooth plate are slidably installed inside the longitudinal slide groove, and the gear is meshed with the tooth plate, and the two movable plates are commonly connected with a rotating column by setting a connecting mechanism, and the outer surface of the rotating column is fixedly connected with evenly distributed thorn columns.

[0014] During operation, in order to improve the refrigeration effect and avoid frost on the surface of the evaporator, a defrost mechanism is set up. First, the stepper motor is connected to an external power supply and driven to rotate, so that the screw fixedly connected to the stepper motor rotates, and the ball seat installed on the outer surface of the screw can move along the screw, and the moving plate connected to the ball seat through the moving mechanism moves accordingly, and the connecting column rotatably installed on the moving plate moves accordingly, and the rotating column connected to the connecting column through the connecting mechanism moves accordingly, and the gear mounted on the surface of the connecting column moves accordingly, and because the gear is meshed with the tooth plate, the gear will rotate while moving, thereby driving the connecting column and the rotating column to rotate. When the rotating column rotates, it will drive the thorn column on the outer surface to rotate, and the thorn column will break the frost layer on the surface of the evaporator, thereby removing the frost layer on the surface of the evaporator.

[0015] Preferably, the moving mechanism includes a slider, a T-shaped slide groove, a hydraulic rod and a slide seat, the outer surface of the ball seat is fixedly connected to the slide seat, T-shaped slide grooves are symmetrically provided on both sides of the outer surface of the slide seat, the upper surface of the moving plate is fixedly connected to a slider adapted to the slide seat, and the slider is inside the slide seat and slides with it, and a hydraulic rod is fixedly connected between the slide seat and the slider.

[0016] During operation, since the distance between the thorn column and the evaporator is fixed, only the frost layer of a certain thickness can be removed. By setting a moving mechanism, the hydraulic rod is driven to extend or contract, and the moving plate fixedly connected to the hydraulic rod through the slider moves accordingly. By setting a longitudinal slide groove, the tooth plate can slide inside it to cooperate with the movement of the hydraulic rod and the moving plate, so that the distance between the moving plate and the evaporator can be adjusted, that is, the distance between the thorn column and the evaporator can be adjusted.

[0017] Preferably, a bellows is fixedly mounted on the front surface of the movable plate, a hot air blower is fixedly mounted on the upper surface of the bellows, and linearly arranged nozzles are symmetrically fixedly mounted on both sides of the outer surface of the bellows.

[0018] During operation, the defrosting efficiency is low if the frost layer is only pierced by the thorn poles, and the frost layer has a certain hardness and needs to be pierced repeatedly by the thorn poles. By setting up a hot air blower, while using the thorn poles to remove the frost layer, the hot air blower is connected to an external power supply. The hot air blower blows hot air into the bellows and then sprays it out from the nozzle. The sprayed hot air contacts the frost layer on the surface of the evaporator, which can accelerate the melting of the frost layer and improve the frost removal efficiency.

[0019] Preferably, a clamping column is slidably inserted into the front surfaces of the two fixed plates, and one end of the clamping column passes through the fixed plate and is fixedly connected to the tooth plate, and the other end of the clamping column is fixedly connected to the limiting plate, and the outer surface of the clamping column is covered with a first spring, one end of the first spring is fixedly connected to the limiting plate, and the other end of the first spring is fixedly connected to the fixed plate.

[0020] During operation, the tooth plate and the horizontal slide groove will wear out during the long-term movement between them, which will increase the distance between the tooth plate and the gear, resulting in the tooth plate and the gear not being engaged. By setting a clamping column, when the tooth plate moves along the longitudinal slide groove, the clamping column and the limit plate fixedly connected to the tooth plate will be driven to move accordingly, and the limit plate will squeeze the first spring, making the first spring compressed. The tooth plate will be affected by the reaction force of the first spring and will move to the side close to the gear direction, thereby ensuring that the gear and the tooth plate are engaged.

[0021] Preferably, the connecting mechanism includes a clamping block, a clamping groove, a circular plate, a second spring and a cylinder, a cylinder is slidably inserted in the middle position of both sides of the outer surface of the rotating column, a circular plate is fixedly connected to the side of the cylinder away from the rotating column, clamping blocks are symmetrically fixedly connected to both sides of the outer surface of the circular plate, and a second spring is sleeved on the outer surface of the cylinder, the upper end of the second spring is fixedly connected to the rotating column, and the lower end of the second spring is fixedly connected to the circular plate, a clamping groove matched with the clamping block and the circular plate is provided on the side of the outer surface of the connecting column close to the circular plate, and the clamping block and the circular plate are clamped in the clamping groove.

[0022] During operation, the thorn column will be worn out after long-term use and needs to be replaced. By setting up a connecting mechanism, when the thorn column needs to be replaced, it is only necessary to move the cylinder so that the clamping block and the circular plate are disengaged from the clamping groove, and the rotating column can be taken out and the rotating column and the thorn column can be replaced. After the replacement is completed, first, the circular plate is pressed, and the second spring is compressed to align the position of the circular plate and the clamping block with the clamping groove, and then the circular plate is released, the second spring extends, and the clamping block and the circular plate are clamped in the clamping groove, so that the rotating column and the thorn column can be installed.

[0023] Preferably, a heating rod is movably inserted on the right side of the outer surface of the screw rod, and an electric wire is electrically connected to the right side of the outer surface of the heating rod. The side of the electric wire away from the heating rod is electrically connected to a power socket, and the power socket is fixedly mounted on the outer surface of the fixed plate.

[0024] During operation, due to the low temperature of the evaporator, frost will appear on the surface of the screw, which will hinder the movement of the ball seat. By setting a heating rod and turning on the switch on the power socket, the heating rod will heat up, which can increase the temperature of the screw and melt the double layer on the surface of the screw, ensuring that the ball seat can move along the screw.

[0025] Preferably, an L-shaped plate is fixedly connected to the outer surface of the fixing plate below the heating rod, a U-shaped plate is fixedly connected to the upper surface of the L-shaped plate, bolts are symmetrically threaded on both sides of the outer surface of the U-shaped plate, and the bolts pass through the U-shaped plate and resist the heating rod.

[0026] During operation, when the screw rod rotates, it will drive the heating rod inside the screw rod to rotate. The rotation of the heating rod will cause the wires to be entangled, which is easy to damage the wires. By setting the L-shaped plate and the U-shaped plate, tightening the bolts so that the bolts are against the heating rod, the heating rod is fixed. When the screw rod rotates, the heating rod is stationary to prevent the wires from being entangled and damaged.

[0027] Preferably, a collecting trough is fixedly connected to the lower surfaces of the two fixing plates, and a drain pipe is fixedly installed on the left bottom of the outer surface of the collecting trough.

[0028] During operation, the scraped double layer falls on the bottom of the evaporator and easily flows into the inside of the evaporator through the gap, causing damage to the evaporator. By setting up a collection tank, the scraped frost layer can be collected and discharged through the drain pipe after the frost layer melts.

[0029] Preferably, a filter plate is fixedly installed inside the collecting tank, the upper surface of the filter plate is provided with evenly distributed filter holes, and a heating plate is embedded inside the filter plate.

[0030] During operation, it takes a certain amount of time for the frost layer to melt, and the discharge efficiency is low. By setting a filter plate, the scraped frost layer falls on the upper surface of the filter plate, and the melted frost blocks flow into the collection tank through the filter holes, and then are discharged from the drain pipe. The unmelted frost blocks remain on the upper surface of the filter plate. By setting a heating plate, the frost blocks on the upper surface of the filter plate can be heated to accelerate melting, and then discharged from the drain pipe.

[0031] Compared with the prior art, the beneficial effect of the present invention is that during the long-term refrigeration process of the existing refrigeration equipment, frost will appear on the surface of the evaporator. When the frost layer is thick, it will affect the heat exchange efficiency of the evaporator, resulting in a serious reduction in the refrigeration effect. By setting up a defrost mechanism, the frost layer on the surface of the evaporator can be scraped off, thereby preventing the frost layer from affecting the evaporator efficiency and improving the refrigeration effect.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 8 , the present invention provides a technical solution:

[0043] A refrigeration device with refrigeration and cold storage functions, such as Figures 1 to 3 As shown, including:

[0044] An evaporator 1, a first connecting pipe 2, a condenser 3 and a throttle valve 4, wherein the evaporator 1, the condenser 3 and the throttle valve 4 are connected in pairs through the first connecting pipe 2;

[0045] A second connecting pipe 5 and a compressor 6, wherein the compressor 6 is connected to the evaporator 1 through the second connecting pipe 5;

[0046] and a defrosting mechanism 7;

[0047] The front side of the outer surface of the evaporator 1 is provided with a defrosting mechanism 7 capable of removing frost layer on the surface of the evaporator 1 .

[0048] When working, during the long-term cooling process of the existing refrigeration equipment, frost will appear on the surface of the evaporator 1. When the frost layer is thick, it will affect the heat exchange efficiency of the evaporator 1, resulting in a serious reduction in the cooling effect. By setting up a defrosting mechanism 7, the frost layer on the surface of the evaporator 1 can be scraped off to avoid the frost layer affecting the efficiency of the evaporator 1 and improve the cooling effect.

[0049] As an embodiment of the present invention, Figures 2 to 3 As shown, the defrosting mechanism 7 includes a fixed plate 71, a ball seat 72, a movable plate 73, a tooth plate 74, a screw 75, a stepping motor 76, a gear 77, a rotating column 78, a thorn column 79, a longitudinal slide groove 710, a connecting column 711 and a transverse slide groove 712;

[0050] The front side of the outer surface of the evaporator 1 is symmetrically fixedly connected with a fixing plate 71, and the tops of the two fixing plates 71 are rotatably mounted with a screw rod 75. The left end of the outer surface of the screw rod 75 penetrates the fixing plate 71 and is fixedly mounted with a stepping motor 76, and the outer surface of the screw rod 75 is rollingly mounted with a ball seat 72. The outer surface of the ball seat 72 is slidably connected with a moving plate 73 by setting a moving mechanism 8. The upper and lower surfaces of the moving plate 73 are rotatably mounted with a connecting column 711, and the outer surface of the connecting column 711 located at the top The surface fixing sleeve is provided with a gear 77, the upper surface of the movable plate 73 is provided with a transverse groove 712, and a tooth plate 74 is slidably installed inside the transverse groove 712. The outer surfaces of the two fixed plates 71 are symmetrically provided with longitudinal grooves 710, and the two sides of the tooth plate 74 are slidably installed inside the longitudinal grooves 710, and the gear 77 is meshed with the tooth plate 74. The two movable plates 73 are connected to a rotating column 78 through a connecting mechanism 12, and the outer surface of the rotating column 78 is fixedly connected with evenly distributed thorn columns 79.

[0051] During operation, in order to improve the refrigeration effect and avoid frost on the surface of the evaporator 1, a defrosting mechanism 7 is set. First, the stepper motor 76 is connected to an external power supply and driven to rotate. The screw rod 75 fixedly connected to the stepper motor 76 rotates, and the ball seat 72 rollingly mounted on the outer surface of the screw rod 75 can move along the screw rod 75. The moving plate 73 connected to the ball seat 72 through the moving mechanism 8 moves accordingly, and the connecting column 711 rotatably mounted on the moving plate 73 moves accordingly. The rotating column 78 connected to the connecting column 711 through the connecting mechanism 12 moves accordingly, and the gear 77 mounted on the surface of the connecting column 711 moves accordingly. Because the gear 77 is meshed with the tooth plate 74, the gear 77 will rotate while moving, thereby driving the connecting column 711 and the rotating column 78 to rotate. When the rotating column 78 rotates, it will drive the thorn column 79 on the outer surface to rotate. The thorn column 79 will break the frost layer on the surface of the evaporator 1, thereby removing the frost layer on the surface of the evaporator 1.

[0052] As an embodiment of the present invention, Figure 4 As shown, the moving mechanism 8 includes a slider 81, a T-shaped slide groove 82, a hydraulic rod 83 and a slide seat 84. The outer surface of the ball seat 72 is fixedly connected to the slide seat 84. T-shaped slide grooves 82 are symmetrically provided on both sides of the outer surface of the slide seat 84. The upper surface of the moving plate 73 is fixedly connected to a slider 81 adapted to the slide seat 84, and the slider 81 is inside the slide seat 84 and slidably cooperates with it. A hydraulic rod 83 is fixedly connected between the slide seat 84 and the slider 81.

[0053] During operation, since the distance between the spike 79 and the evaporator 1 is fixed, only a frost layer of a certain thickness can be removed. By setting the moving mechanism 8, the hydraulic rod 83 is driven to extend or contract, and the moving plate 73 fixedly connected to the hydraulic rod 83 through the slider 81 moves accordingly. By setting the longitudinal slide groove 710, the tooth plate 74 can slide inside it to cooperate with the movement of the hydraulic rod 83 and the moving plate 73, so that the distance between the moving plate 73 and the evaporator 1 can be adjusted, that is, the distance between the spike 79 and the evaporator 1 can be adjusted. It should be noted that: after the hydraulic rod 83 is fully contracted, the outermost end of the spike 79 does not contact the outer surface of the evaporator 1.

[0054] As an embodiment of the present invention, Figure 3 As shown, a wind box 14 is fixedly mounted on the front surface of the movable plate 73 , a hot air blower 13 is fixedly mounted on the upper surface of the wind box 14 , and linearly arranged nozzles 15 are symmetrically fixedly mounted on both sides of the outer surface of the wind box 14 .

[0055] During operation, the frost layer is only pierced by the thorn column 79, and the defrosting efficiency is low. In addition, the frost layer has a certain hardness and needs to be repeatedly pierced by the thorn column 79. By setting a hot air blower 13, while using the thorn column 79 to remove the frost layer, the hot air blower 13 is connected to an external power supply. The hot air blower 13 blows hot air into the bellows 14 and then sprays it from the nozzle 15. The sprayed hot air contacts the frost layer on the surface of the evaporator 1, which can accelerate the melting of the frost layer and improve the removal efficiency of the frost layer.

[0056] As an embodiment of the present invention, Figure 5 As shown, a clamping column 10 is slidably inserted into the front surface of the two fixed plates 71, and one end of the clamping column 10 passes through the fixed plate 71 and is fixedly connected to the tooth plate 74, and the other end of the clamping column 10 is fixedly connected to the limiting plate 11, and the outer surface of the clamping column 10 is covered with a first spring 9, one end of the first spring 9 is fixedly connected to the limiting plate 11, and the other end of the first spring 9 is fixedly connected to the fixed plate 71.

[0057] When the tooth plate 74 and the transverse groove 712 move relative to each other for a long time, wear will occur, which will increase the distance between the tooth plate 74 and the gear 77, resulting in the tooth plate 74 and the gear 77 not meshing. By setting the clamping column 10, when the tooth plate 74 moves along the longitudinal groove 710, the clamping column 10 and the limit plate 11 fixedly connected to the tooth plate 74 will be driven to move accordingly. The limit plate 11 squeezes the first spring 9, making the first spring 9 compressed. The tooth plate 74 is subjected to the reaction force of the first spring 9 and will move to the side close to the gear 77, thereby ensuring that the gear 77 is meshed with the tooth plate 74.

[0058] As an embodiment of the present invention, Figure 6As shown, the connecting mechanism 12 includes a clamping block 121, a clamping groove 122, a circular plate 123, a second spring 124 and a cylinder 125. The cylinder 125 is slidably inserted in the middle position on both sides of the outer surface of the rotating column 78, and the side of the cylinder 125 away from the rotating column 78 is fixedly connected with a circular plate 123. The clamping blocks 121 are symmetrically fixedly connected on both sides of the outer surface of the circular plate 123, and the outer surface of the cylinder 125 is sleeved with a second spring 124, the upper end of the second spring 124 is fixedly connected to the rotating column 78, and the lower end of the second spring 124 is fixedly connected to the circular plate 123. The outer surface of the connecting column 711 is provided with a clamping groove 122 that is compatible with the clamping block 121 and the circular plate 123 on the side close to the circular plate 123, and the clamping block 121 and the circular plate 123 are clamped in the clamping groove 122.

[0059] During operation, the thorn column 79 will be worn out after long-term use and needs to be replaced. By setting the connecting mechanism 12, when the thorn column 79 needs to be replaced, it is only necessary to move the cylinder 125 to the side close to the rotating column 78, so that the clamping block 121 and the circular plate 123 are disengaged from the clamping groove 122, and the rotating column 78 can be taken out, and the rotating column 78 and the thorn column 79 can be replaced. After the replacement is completed, first, the circular plate 123 is pressed, and the second spring 124 is compressed to align the position of the circular plate 123 and the clamping block 121 with the clamping groove 122, and then the circular plate 123 is released, the second spring 124 extends, and pushes the clamping block 121 and the circular plate 123 to be clamped in the clamping groove 122, so that the rotating column 78 and the thorn column 79 can be installed.

[0060] As an embodiment of the present invention, Figure 7 As shown, a heating rod 16 is movably inserted on the right side of the outer surface of the screw rod 75, and a wire 17 is electrically connected to the right side of the outer surface of the heating rod 16. The side of the wire 17 away from the heating rod 16 is electrically connected to a power socket 18, and the power socket 18 is fixedly mounted on the outer surface of the fixed plate 71.

[0061] During operation, due to the low temperature of the evaporator 1, frost will appear on the surface of the screw rod 75, which will hinder the movement of the ball seat 72. By setting a heating rod 16 and turning on the switch on the power seat 18, the heating rod 16 will generate heat, which can increase the temperature of the screw rod 75, so that the double layer on the surface of the screw rod 75 melts, ensuring that the ball seat 72 can move along the screw rod 75.

[0062] As an embodiment of the present invention, Figure 7 As shown, the outer surface of the fixing plate 71 is fixedly connected with an L-shaped plate 19 below the heating rod 16, and the upper surface of the L-shaped plate 19 is fixedly connected with a U-shaped plate 20. Bolts 21 are symmetrically threadedly inserted on both sides of the outer surface of the U-shaped plate 20. The bolts 21 pass through the U-shaped plate 20 and resist the heating rod 16.

[0063] During operation, when the screw rod 75 rotates, the heating rod 16 inside the screw rod 75 will be driven to rotate. The rotation of the heating rod 16 will cause the wire 17 to be entangled, which is easy to damage the wire 17. By setting the L-shaped plate 19 and the U-shaped plate 20, tightening the bolt 21, the bolt 21 is pressed against the heating rod 16 to fix the heating rod 16. When the screw rod 75 rotates, the heating rod 16 is stationary to prevent the wire 17 from being entangled and damaged.

[0064] As an embodiment of the present invention, Figure 8 As shown, the lower surfaces of the two fixing plates 71 are fixedly connected with the collecting trough 22 , and the left bottom of the outer surface of the collecting trough 22 is fixedly installed with a drain pipe 25 .

[0065] During operation, the scraped double layer falls on the bottom surface of the evaporator 1 and easily flows into the inside of the evaporator 1 through the gap, causing damage to the evaporator 1. By setting up a collection tank 22, the scraped frost layer can be collected and discharged through the drain pipe 25 after the frost layer melts.

[0066] As an embodiment of the present invention, Figure 8 As shown, a filter plate 23 is fixedly installed inside the collecting tank 22 , and evenly distributed filter holes 24 are opened on the upper surface of the filter plate 23 . A heating plate 26 is embedded inside the filter plate 23 .

[0067] During operation, it takes a certain amount of time for the frost layer to melt, and the discharge efficiency is low. By setting the filter plate 23, the scraped frost layer falls on the upper surface of the filter plate 23, and the melted frost blocks flow into the collection tank 22 through the filter holes 24, and then are discharged from the drain pipe 25. The unmelted frost blocks remain on the upper surface of the filter plate 23. The heating plate 26 is connected to an external power supply, and the heating plate 26 generates heat, which can heat the frost blocks on the upper surface of the filter plate 23, accelerate the melting, and then discharge them from the drain pipe 25.

[0068] Instructions for use: When the present invention is in use, first, the stepper motor 76 is connected to an external power source and driven to rotate, so that the screw rod 75 fixedly connected to the stepper motor 76 rotates, and the ball seat 72 rollingly installed on the outer surface of the screw rod 75 can move along the screw rod 75, and the moving plate 73 connected to the ball seat 72 through the moving mechanism 8 moves accordingly, and the connecting column 711 rotatably installed on the moving plate 73 moves accordingly, and the rotating column 78 connected to the connecting column 711 through the connecting mechanism 12 moves accordingly, and the gear 77 mounted on the surface of the connecting column 711 moves accordingly. Because the gear 77 is meshed with the tooth plate 74, the gear 77 will rotate while moving, thereby driving the connecting column 711 and the rotating column 78 to rotate. When the rotating column 78 rotates, it will drive the thorn column 79 on the outer surface to rotate, and the thorn column 79 will break the frost layer on the surface of the evaporator 1, thereby removing the frost layer on the surface of the evaporator 1.
