Description

Technical Field

[0001] The invention relates to the technical field of industrial air conditioners, and in particular to an industrial direct injection air conditioner. Background Art

[0002] Industrial air conditioners are air conditioners that provide environmental temperature, humidity, and cleanliness guarantees for the reliable operation of industrial product production processes or industrial process equipment. The technical principles of industrial air conditioners are mainly based on refrigeration technology and air treatment technology. Refrigeration technology reduces air temperature by absorbing heat through the evaporation of refrigerant in the evaporator, while air treatment technology includes air filtration, humidification, dehumidification, sterilization, etc., to meet the strict requirements of industrial production for air quality. At present, in the existing technology, direct injection air conditioners are famous for their four-sided air outlets and long air supply heads. They can provide cold / hot air in all directions to meet the temperature regulation needs of large spaces or specific areas. At the same time, their long air supply heads can transport cold / hot air to a longer distance to ensure uniform temperature distribution in the entire space. However, with the increase in air supply heads, the wind impact force required by direct injection air conditioners during the air outlet process also increases accordingly. Therefore, it is easy to cause direct injection air conditioners to generate certain noise during the air outlet process. In view of this, an industrial direct injection air conditioner is proposed. Summary of the invention

[0003] The main purpose of the present invention is to provide an industrial direct injection air conditioner that can solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention proposes the following technical solutions:

[0005] An industrial direct injection air conditioner comprises a casing, on the inner wall of which a compressor, a condenser, an expansion valve, an evaporator and a fan are fixedly mounted, a noise reduction mechanism is arranged in the casing, a defrosting component and an auxiliary flow component are arranged in the noise reduction mechanism, and the noise reduction mechanism comprises:

[0006] A noise reduction shell, the noise reduction shell is fixedly installed inside the casing, and a through pipe is fixedly installed in the noise reduction shell;

[0007] A sliding silencer pipe, wherein the sliding silencer pipe is slidably connected to the inner wall of the through pipe, a fixed silencer pipe is fixedly connected to the inner wall of the through pipe, and the sliding silencer pipe and the fixed silencer pipe are elastically connected via an elastic telescopic rod;

[0008] The discharge port is opened on the outer wall of the through pipe, and a solenoid valve is arranged on the discharge port. After the frost on the outer walls of the sliding silencer pipe and the fixed silencer pipe is removed to form water droplets, the water droplets can flow downward on the outer walls of the sliding silencer pipe and the fixed silencer pipe to the discharge port. By opening the solenoid valve, the discharge port can discharge the water droplets.

[0009] Preferably, the fixed silencer pipe is sleeved by the sliding silencer pipe, a through hole is provided on a side of the sliding silencer pipe away from the fixed silencer pipe, and the exhaust port is located at the bottom of the through hole.

[0010] Preferably, a resonance cavity is formed between the sliding silencer pipe, the fixed silencer pipe and the through pipe. When the sliding silencer pipe moves in the inner wall of the through pipe toward the fixed silencer pipe, the space of the resonance cavity is reduced, and the frequency of the resonance cavity is increased to reduce high-frequency noise.

[0011] Preferably, a guide groove is provided on the outer wall of the noise reduction shell, a collecting port is provided on the outer wall of the noise reduction shell, a drain pipe is fixedly connected to the side wall of the noise reduction shell, the drain pipe passes through the casing and is fixedly connected to the casing, and water droplets attached to the outer wall of the noise reduction shell can move downward to the collecting port through the guide groove, and at the same time, through the use of the drain pipe, the collected condensed water can be discharged in a centralized manner.

[0012] Preferably, the defrost assembly includes a rotating shaft, a fixed sleeve is fixedly connected to the outer wall of the rotating shaft, an arc-shaped blade is fixedly connected to the outer wall of the fixed sleeve, a damping sleeve is sleeved on the outer wall of the rotating shaft, a heat-conducting copper tube is fixedly connected to the outer wall of the damping sleeve, and a conical ring is fixedly connected to the end of the rotating shaft away from the sliding silencer tube. During the flow of cold air, the cold air will pass through the arc-shaped blades. At this time, the arc-shaped blades drive the rotating shaft to rotate, and then the rotating shaft moves relative to the damping sleeve. At the same time, the arc-shaped blades block and slow down the flow of cold air, thereby reducing noise generation by reducing the formation of turbulence and vortices.

[0013] Preferably, the damping sleeve and the heat-conducting copper tube are provided in two groups, one group of the damping sleeve and the heat-conducting copper tube is arranged at the air inlet of the sliding silencer pipe, and the other group of the damping sleeve and the heat-conducting copper tube is arranged at the air outlet of the fixed silencer pipe. The heat-conducting copper tube arranged at the air inlet of the sliding silencer pipe is fixed to the inner wall of the sliding silencer pipe, and the heat-conducting copper tube arranged at the air outlet of the fixed silencer pipe is fixed to the inner wall of the fixed silencer pipe.

[0014] Preferably, the rotation of the arc-shaped blade drives the rotating shaft to move relative to the damping sleeve and generate heat. The heat-conducting copper tube transfers the heat of the damping sleeve. During this process, heat is generated by mechanical friction. The heat is transferred to the damping sleeve through the tightly fitting heat-conducting copper tube, and further transferred to the inner walls of the sliding silencer pipe and the fixed silencer pipe. Due to the excellent thermal conductivity of the heat-conducting copper tube, the heat can effectively melt the frost formed on the sliding silencer pipe and the fixed silencer pipe, thereby achieving a defrosting effect.

[0015] Preferably, the auxiliary flow component includes an air bin, which is fixedly connected to the inner wall of the noise reduction shell, a piston in the inner wall of the air bin is connected to a piston rod, the piston rod and the inner wall of the air bin are elastically connected by a return spring, a hinged rod is hinged at the bottom of the piston rod, a one-way exhaust port and a one-way air inlet are fixedly connected to the outer wall of the air bin, one end of the one-way exhaust port and the one-way air inlet are connected to the air bin, and the other end of the one-way exhaust port and the one-way air inlet are connected to a through pipe.

[0016] Preferably, the piston rod passes through the through tube and is slidably connected to the through tube, and the end of the hinged rod away from the piston rod is hinged to the conical ring. The rotation of the arc-shaped blade drives the rotating shaft to rotate, and then drives the conical ring to rotate, so that the hinged rod drives the piston rod to reciprocate up and down. During this process, when the piston rod compresses the reset spring, the gas in the air chamber is squeezed into the resonance cavity through the one-way exhaust port. When the piston rod moves downward and the reset spring is reset, the air chamber sucks in gas through the one-way air inlet port, thereby realizing the flow of gas in the resonance cavity and improving the effect of removing frost on the outer walls of the sliding silencer pipe and the fixed silencer pipe.

[0017] Preferably, a hot air inlet and a cold air outlet are provided on the outer wall of the housing. By using a compressor, a condenser, an expansion valve, an evaporator and a fan, hot air can be sucked in through the hot air inlet. Then, the sucked hot air passes through the compressor, which can increase the pressure and temperature of the refrigerant, so that it has enough energy to release heat in the condenser. Subsequently, the high-temperature and high-pressure refrigerant enters the condenser. In the condenser, the refrigerant exchanges heat with the surrounding air or water to release the heat it carries. Then, the liquid refrigerant passes through the expansion valve. In the evaporator, the liquid refrigerant evaporates rapidly and absorbs a large amount of heat. This process reduces the air temperature around the evaporator to form cold air. Finally, the cold air cooled by the evaporator is discharged through the cold air outlet under the action of the fan.

[0018] The present invention provides an industrial direct injection air conditioner having the following beneficial effects:

[0019] (1) The use of the industrial direct injection air conditioner noise reduction mechanism and the defrost assembly enables the sliding silencer to move in the direction of the fixed silencer in the inner wall of the through pipe when the flow rate of the cold air increases, the space of the resonance cavity is reduced, the frequency of the resonance cavity is increased to reduce high-frequency noise, and the noise reduction effect is improved. At the same time, during the flow of cold air, the cold air will pass through the arc blades. At this time, the arc blades drive the rotating shaft to rotate, and then the rotating shaft moves relative to the damping sleeve. At the same time, the arc blades block and slow down the flow of cold air, and reduce the noise generation by reducing the formation of turbulence and vortex.

[0020] (2) The industrial direct injection air conditioner uses a defrost assembly. The rotation of the arc-shaped blades drives the shaft to rotate, which will move relative to the damping sleeve, generating heat through mechanical friction. This heat is transferred to the inner walls of the sliding silencer pipe and the fixed silencer pipe through the tightly fitting thermal copper tube. Due to the excellent thermal conductivity of the thermal copper tube, the heat can effectively melt the frost formed on the sliding silencer pipe and the fixed silencer pipe, thereby achieving a defrosting effect and preventing the condensed water generated when spraying cold air in summer from falling to the ground and causing unnecessary short-circuit hazards.

[0021] (3) The industrial direct injection air conditioner uses a defrost component and an auxiliary flow component, so that the arc-shaped blades rotate to drive the rotating shaft to rotate, and the conical ring is driven to rotate, so that the hinged rod drives the piston rod to reciprocate up and down. During this process, when the piston rod compresses the reset spring, the gas in the air chamber is squeezed into the resonance cavity through the one-way exhaust port. When the piston rod moves downward and the reset spring is reset, the air chamber inhales gas through the one-way air inlet port, realizing the flow of gas in the resonance cavity, improving the effect of removing frost on the outer walls of the sliding silencer pipe and the fixed silencer pipe, and at the same time, assisting water droplets to flow downward on the outer walls of the sliding silencer pipe and the fixed silencer pipe, making it easier for water droplets to be discharged from the discharge port.

[0032] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0033] 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.

[0034] See also Figure 1-Figure 8 The present invention proposes an industrial direct injection air conditioner, including a casing 1, a hot air inlet 101 and a cold air outlet 102 are opened on the outer wall of the casing 1, a compressor 2, a condenser 3, an expansion valve 4, an evaporator 5 and a fan 6 are fixedly installed on the inner wall of the casing 1, a noise reduction mechanism 7 is arranged in the casing 1, and a defrosting component 8 and an auxiliary flow component 9 are arranged in the noise reduction mechanism 7. Through the use of the compressor 2, the condenser 3, the expansion valve 4, the evaporator 5 and the fan 6, hot air can be sucked in through the hot air inlet 101, and then the sucked hot air passes through the compressor 2, which can increase the pressure and temperature of the refrigerant, so that it has enough energy to release heat in the condenser 3, and then the high-temperature and high-pressure refrigerant enters the condenser 3. In the condenser 3, the refrigerant exchanges heat with the surrounding air or water to release the heat it carries. Then, the liquid refrigerant passes through the expansion valve 4. In the evaporator 5, the liquid refrigerant evaporates rapidly and absorbs a large amount of heat. This process reduces the air temperature around the evaporator 5 to form cold air. Finally, the cold air cooled by the evaporator 5 is discharged through the cold air outlet 102 under the action of the fan 6.

[0035] In the embodiment of the present invention, in order to be able to perform noise reduction processing when the cold air is ejected from the cold air outlet 102, specifically, the noise reduction mechanism 7 includes a noise reduction shell 71, a sliding silencer pipe 73 and an exhaust port 76, the noise reduction shell 71 is fixedly installed inside the casing 1, a through pipe 72 is fixedly installed in the noise reduction shell 71, the sliding silencer pipe 73 is slidably connected to the inner wall of the through pipe 72, a fixed silencer pipe 74 is fixedly connected to the inner wall of the through pipe 72, the fixed silencer pipe 74 is sleeved by the sliding silencer pipe 73, and a through pipe is provided on the side of the sliding silencer pipe 73 away from the fixed silencer pipe 74. The sliding silencer 73 and the fixed silencer 74 are elastically connected by an elastic telescopic rod 75. The exhaust port 76 is opened on the outer wall of the through pipe 72. The exhaust port 76 is located at the bottom of the through pipe 72. The exhaust port 76 is provided with an electromagnetic valve 77. A resonance cavity is formed among the sliding silencer 73, the fixed silencer 74 and the through pipe 72. When the flow rate of the cold air increases, the cold air squeezes the sliding silencer 73, so that the sliding silencer 73 moves in the inner wall of the through pipe 72 toward the fixed silencer 74, and the space of the resonance cavity is reduced, and the frequency of the resonance cavity is increased to reduce high-frequency noise.

[0036] Furthermore, in order to further improve the noise reduction effect and remove the frost attached to the sliding silencer pipe 73 and the fixed silencer pipe 74, specifically, the defrost assembly 8 includes a rotating shaft 81, a fixed sleeve 82 is fixedly connected to the outer wall of the rotating shaft 81, an arc-shaped blade 83 is fixedly connected to the outer wall of the fixed sleeve 82, a damping sleeve 84 is sleeved on the outer wall of the rotating shaft 81, and a heat-conducting copper tube 85 is fixedly connected to the outer wall of the damping sleeve 84. The rotating shaft 81 is away from the sliding silencer pipe 73 and the fixed silencer pipe 74. One end of the movable silencer pipe 73 is fixedly connected with a conical ring 86, and two groups of damping sleeves 84 and heat-conducting copper tubes 85 are provided. One group of damping sleeves 84 and heat-conducting copper tubes 85 are provided at the air inlet of the sliding silencer pipe 73, and one group of damping sleeves 84 and heat-conducting copper tubes 85 are provided at the air outlet of the fixed silencer pipe 74. The heat-conducting copper tubes 85 provided at the air inlet of the sliding silencer pipe 73 are fixed to the inner wall of the sliding silencer pipe 73, and are provided at the air outlet of the fixed silencer pipe 74. The heat-conducting copper tube 85 is fixed to the inner wall of the fixed silencer tube 74. Through the flow of cold air, the cold air will pass through the arc blades 83. At this time, the arc blades 83 rotate and drive the rotating shaft 81 to move relative to the damping sleeve 84 and generate heat. The heat-conducting copper tube 85 transfers the heat of the damping sleeve 84. At the same time, the arc blades 83 block and slow down the flow of cold air, reduce the formation of turbulence and vortex, and reduce noise. In the process of rotation of the rotating shaft 81 relative to the damping sleeve 84, heat is generated by mechanical friction. This heat is transferred to the inner walls of the sliding silencer tube 73 and the fixed silencer tube 74 through the tightly fitted heat-conducting copper tube 85. Due to the excellent thermal conductivity of the heat-conducting copper tube 85, the heat can effectively melt the frost formed on the sliding silencer tube 73 and the fixed silencer tube 74, thereby achieving a defrosting effect and avoiding the condensed water generated when spraying cold air in summer from falling to the ground and causing unnecessary short-circuit risks.

[0037] In the embodiment of the present invention, in order to collect and discharge the condensed water in the noise reduction mechanism 7, specifically, the auxiliary flow component 9 includes an air bin 91, which is fixedly connected to the inner wall of the noise reduction shell 71, and a piston in the inner wall of the air bin 91 is connected to a piston rod 92, and the piston rod 92 is elastically connected to the inner wall of the air bin 91 through a return spring, and a hinged rod 93 is hinged at the bottom of the piston rod 92, and a one-way exhaust port 94 and a one-way air inlet 95 are fixedly connected to the outer wall of the air bin 91, one end of the one-way exhaust port 94 and the one-way air inlet 95 are connected to the air bin 91, and the other end of the one-way exhaust port 94 and the one-way air inlet 95 are connected to the through pipe 72, the piston rod 92 passes through the through pipe 72 and is slidably connected to the through pipe 72, and the hinged rod 93 is away from the piston One end of the rod 92 is hinged to the conical ring 86. When the arc-shaped blade 83 rotates and drives the rotating shaft 81 to rotate, the conical ring 86 is driven to rotate, so that the hinged rod 93 drives the piston rod 92 to reciprocate up and down. During this process, when the piston rod 92 compresses the reset spring, the gas in the air chamber 91 is squeezed into the resonance cavity through the one-way exhaust port 94. When the piston rod 92 moves downward and the reset spring is reset, the air chamber 91 inhales gas through the one-way air inlet port 95, thereby realizing the flow of gas in the resonance cavity and improving the frost removal effect on the outer walls of the sliding silencer pipe 73 and the fixed silencer pipe 74. At the same time, it assists water droplets to flow downward on the outer walls of the sliding silencer pipe 73 and the fixed silencer pipe 74, and by opening the solenoid valve 77, the discharge port 76 can discharge the water droplets.

[0038] Furthermore, a guide groove 711 is provided on the outer wall of the noise reduction shell 71, a collecting port 712 is provided on the outer wall of the noise reduction shell 71, and a drain pipe 713 is fixedly connected to the side wall of the noise reduction shell 71. The drain pipe 713 passes through the casing 1 and is fixedly connected to the casing 1. When the device is not in use, the frost on the noise reduction shell 71 will gradually melt into water droplets, and the water droplets will slide downward through the guide groove 711 to the collecting port 712, and then enter the noise reduction shell 71 to be collected, and then the condensed water is discharged through the drain pipe 713.

[0039] It should be noted that the above-mentioned electrical components are all existing technology products. Technical personnel in this field select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. This application does not make specific restrictions here.

[0040] When in use, hot air is sucked in through the hot air inlet 101. The sucked hot air passes through the compressor 2, which can increase the pressure and temperature of the refrigerant, so that it has enough energy to release heat in the condenser 3. Then, the high-temperature and high-pressure refrigerant enters the condenser 3. In the condenser 3, the refrigerant exchanges heat with the surrounding air or water to release the heat it carries. Then, the liquid refrigerant passes through the expansion valve 4. In the evaporator 5, the liquid refrigerant evaporates rapidly and absorbs a large amount of heat. This process reduces the temperature of the air around the evaporator 5 to form cold air. The cold air cooled by the evaporator 5 is discharged through the cold air outlet 102 under the action of the fan 6. In this process, the cold air squeezes the sliding silencer 73, so that when the sliding silencer 73 moves in the inner wall of the through pipe 72 toward the fixed silencer 74, the space of the resonance cavity is reduced, and the frequency of the resonance cavity is increased to reduce high-frequency noise.

[0041] At the same time, through the flow of cold air, the cold air will pass through the arc blades 83. At this time, the arc blades 83 rotate to drive the rotating shaft 81 to rotate. The arc blades 83 block and slow down the flow of cold air, and reduce the formation of turbulence and vortex, thereby reducing noise. In the process of the rotating shaft 81 rotating relative to the damping sleeve 84, heat is generated by mechanical friction. The heat is transferred to the inner walls of the sliding silencer pipe 73 and the fixed silencer pipe 74 through the tightly fitted heat-conducting copper tube 85. Due to the excellent heat conductivity of the heat-conducting copper tube 85, the heat can effectively melt the frost formed on the sliding silencer pipe 73 and the fixed silencer pipe 74.

[0042] At the same time, as the arc-shaped blades 83 rotate and drive the rotating shaft 81 to rotate, the conical ring 86 is driven to rotate, so that the hinged rod 93 drives the piston rod 92 to reciprocate up and down. During this process, when the piston rod 92 compresses the reset spring, the gas in the air chamber 91 is squeezed into the resonance cavity through the one-way exhaust port 94. When the piston rod 92 moves downward and the reset spring is reset, the air chamber 91 inhales gas through the one-way air inlet port 95, thereby realizing the flow of gas in the resonance cavity and assisting the defrosting of the outer walls of the sliding silencer 73 and the fixed silencer 74.
