Description

Technical Field

[0001] The invention relates to the technical field of electromechanical equipment, and in particular to a self-heating structure of an outdoor compressor of an air conditioner. Background Art

[0002] The air conditioning compressor is one of the most common electromechanical devices in daily life. It plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. It is the main component that determines the refrigeration effect of the air conditioning system. The air conditioning compressor is generally installed in the outdoor unit. The air conditioning compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant also changes from gas to liquid, and the pressure increases.

[0003] For example, in the patent with application number: CN201820492792.2, a compressor compartment and an air conditioner outdoor unit are disclosed. A recess is set at the connection between the first side plate and the rear plate, and the stop valve is set in the recess. The outer end of the stop valve is in the same plane as the first side plate or embedded in the first side plate. This design structure, without changing the overall dimensions of the air conditioner outdoor unit, that is, without changing the lateral spacing between the outer end face of the stop valve and the second side plate, is equivalent to moving the first side plate outward, increasing the lateral spacing between the first side plate and the partition, that is, expanding the internal space of the compressor compartment, and meeting the installation requirements of compressors of different sizes. At the same time, a shielding plate for shielding the stop valve is set on the outside of the recess to prevent the stop valve from being touched due to accidental bumps and other reasons, which affects the normal working state of the air conditioner outdoor unit.

[0004] However, as for the compressor of the existing air-conditioning outdoor unit, it has no self-heating structure, so the temperature of the compressor will rise after long-term use. If the compressor cannot dissipate heat in time, it will affect the working efficiency and working effect of the compressor. The flexibility and stability are poor and the practicality is not high. Summary of the invention

[0005] In view of this, the present invention provides a self-heating structure of an air-conditioning outdoor unit compressor, which has a self-heating component. When the compressor body is working, the high-pressure fluid inside it can act on the driving mechanism, so that under the drive of the driving mechanism, the self-heating effect of the compressor body can be achieved through the heat dissipation mechanism. No additional power drive is required, and the use is flexible and convenient. The heat dissipation efficiency of the heat dissipation mechanism can be freely adjusted for use, so that it can be adapted to use in different environments, ensuring that the compressor body is always in the best working state, and has strong flexibility, stability, adaptability and practicality.

[0006] The present invention provides a self-heating structure of an air-conditioning outdoor unit compressor, specifically comprising: a compressor body, wherein the compressor body is mounted inside the air-conditioning outdoor unit, and a self-heating component is provided on the top of the compressor body; the natural heat component is composed of a driving mechanism and a heat dissipation mechanism, the driving mechanism comprises a mounting shell and a driving fan disk, the mounting shell is fixedly mounted on the top of the shell of the compressor body, and the driving fan disk is rotatably connected to the inside of the mounting shell; the heat dissipation mechanism comprises a rotating disk, heat dissipation blades, an adjusting disk and a locking column, the rotating disk is rotatably connected to the top of the mounting shell, and the heat dissipation blades are rotatably connected to the side of the rotating disk, the adjusting disk is rotatably connected to the inside of the rotating disk, and the locking column is plugged into the inside of the rotating disk.

[0007] Furthermore, a conversion channel and a connection channel are respectively provided inside the mounting shell, the conversion channel is connected to the high-pressure fluid pipe of the compressor body, and the connection channel is connected to the pipeline of the air-conditioning condenser.

[0008] Furthermore, a driving fan blade is provided at the bottom of the drive fan disc, and the conversion channel is located in the tangential direction of the drive fan disc. A driving shaft is provided at the top of the drive fan disc, and the driving shaft is fixedly mounted at the bottom of the rotating disc.

[0009] Furthermore, a positioning gear is provided at one end of the rotating shaft of the heat dissipation fan blade, and an adjusting gear is provided on the top of the adjusting disk, and the teeth of the adjusting gear and the positioning gear are meshed for transmission.

[0010] Furthermore, a synchronization column is provided on the top of the adjusting disk, and the cross-sectional shape of the synchronization column is a regular polygon. A synchronization groove is provided inside the locking column, and the synchronization column is inserted into the synchronization groove.

[0011] Furthermore, a locking top spring is provided inside the synchronization column, and two ends of the locking top spring respectively abut against the inside of the synchronization column and the locking column.

[0012] Furthermore, a locking gear is provided at the bottom of the column body of the locking column, and a locking control groove is provided inside the rotating disk, and the locking gear is inserted into the locking control groove.

[0013] Furthermore, the locking control groove is composed of a locking tooth groove and an avoidance groove, and the locking tooth groove is located at the top of the avoidance groove, and the inner diameter of the avoidance groove is larger than the outer diameter of the locking gear.

[0014] Furthermore, heat dissipation fins are provided outside the shell of the compressor body.

[0015] Beneficial Effects 1. When the device is in use, under the action of the self-heating component, when the compressor body is working, the high-pressure fluid inside it can act on the driving mechanism, so that the self-heating effect of the compressor body can be achieved through the heat dissipation mechanism under the drive of the driving mechanism. No additional power drive is required, the use is flexible and convenient, and the heat dissipation efficiency of the heat dissipation mechanism can be freely adjusted for use, so that it can be adapted to use in different environments, ensuring that the compressor body is always in the best working state, thereby improving the flexibility, adaptability, stability and practicality of the device.

[0016] 2. When the compressor body is working, it can drive the heat dissipation mechanism through the driving mechanism to realize the heat dissipation operation of the compressor body. When the high-pressure fluid flows out from the high-pressure fluid pipe of the compressor body, the high-pressure fluid can drive the fan blades through the conversion channel to drive the driving fan disc to rotate. When the driving fan disc rotates, it can drive the rotating disc to rotate through the driving shaft, so that the heat dissipation mechanism can blow air onto the compressor body to achieve the heat dissipation effect. At the same time, the heat dissipation fins on the outside of the compressor body can improve the heat dissipation effect of the compressor body and the heat dissipation mechanism, further ensuring that the compressor body can always be in the best working state during use, and the stability is extremely strong.

[0017] 3. The use angle of the cooling fan blades can be freely adjusted through the locking column. Therefore, when the use angle of the cooling fan blades is changed, the heat dissipation effect generated by the cooling fan blades within the unit rotation rate of the rotating disk (since the kinetic energy of the high-pressure fluid output by the compressor body is fixed, the rotation rate of the rotating disk is also fixed) will also change, which can adapt to installation and use in different environments. When the locking column is pressed and rotated, the locking gear will enter the inside of the avoidance groove after the locking column is pressed so that the locking column can rotate freely. When the locking column rotates, the synchronous groove can drive the adjusting disk to rotate synchronously through the synchronous column, so that when the adjusting disk rotates, the adjusting gear can drive the cooling fan blades to rotate through the positioning gear, thereby realizing the change of the strength of the heat dissipation effect generated by the cooling fan blades within the unit rotation rate of the rotating disk. It is easy to adjust and has strong flexibility and adaptability.

[0018] 4. When the heat dissipation mechanism is in the reset state, the use angle of the heat dissipation fan blades is fixed, so that the rotating disk can stably provide heat dissipation effect for the compressor body when rotating. In the reset state, the locking gear is inserted into the locking tooth groove under the action of the locking top spring, so that the locking column cannot rotate, and the use state of the adjustment disk is also locked and cannot rotate under the cooperation of the synchronization column and the synchronization groove, so that the heat dissipation fan blades cannot rotate under the cooperation of the positioning gear and the adjustment gear, thereby maintaining the stability of the heat dissipation fan blades during use, and there will be no accidental change in the use angle that will cause the heat dissipation effect to change, and the stability is extremely strong.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention.

[0032] Example: Please refer to Figures 1 to 9 As shown: The present invention provides a self-heating structure of an air conditioner outdoor unit compressor, comprising a compressor body 1, the compressor body 1 is installed inside the air conditioner outdoor unit, and a self-heating component is provided on the top of the compressor body 1; under the action of the self-heating component, when the compressor body 1 is working, the high-pressure fluid inside it can act on the driving mechanism 2, so that the self-heating effect of the compressor body 1 can be achieved through the heat dissipation mechanism 3 under the drive of the driving mechanism 2, without the need for additional power drive, and the use is flexible and convenient, and the heat dissipation efficiency of the heat dissipation mechanism 3 can be freely adjusted for use, so that it can be adapted to use in different environments, ensuring that the compressor body 1 is always in the best working state state; the natural heat component is composed of a driving mechanism 2 and a heat dissipation mechanism 3, the driving mechanism 2 includes a mounting shell 201 and a driving fan disc 202, the mounting shell 201 is fixedly mounted on the top of the shell of the compressor body 1, and the driving fan disc 202 is rotatably connected to the inside of the mounting shell 201; the heat dissipation mechanism 3 includes a rotating disk 301, a heat dissipation fan blade 302, an adjusting disk 303 and a locking column 304, the rotating disk 301 is rotatably connected to the top of the mounting shell 201, and the heat dissipation fan blade 302 is rotatably connected to the side of the rotating disk 301, the adjusting disk 303 is rotatably connected to the inside of the rotating disk 301, and the locking column 304 is inserted into the inside of the rotating disk 301.

[0033] The compressor body 1 is electrically connected to an external power supply and a control device. Its specific structure and working principle are existing mature technologies and will not be described here.

[0034] Among them, the interior of the mounting shell 201 is respectively provided with a conversion channel 2011 and a connecting channel 2012, the conversion channel 2011 is connected to the high-pressure fluid pipe 101 of the compressor body 1, and the connecting channel 2012 is connected to the pipeline of the air-conditioning condenser. In use, the compressor body 1 can drive the heat dissipation mechanism 3 to work through the driving mechanism 2 when working, thereby realizing the heat dissipation operation of the compressor body 1. When the high-pressure fluid flows out of the high-pressure fluid pipe 101 of the compressor body 1, the bottom of the disk body of the driving fan disk 202 is provided with a driving fan blade 2021, and the conversion channel 2011 is located in the tangential direction of the driving fan disk 202, and the top of the driving fan disk 202 is provided with a driving shaft 2022, and the driving shaft 2022 is fixedly mounted on the rotating disk 301. At the bottom of the compressor body 1, the high-pressure fluid can drive the fan blades 2021 through the conversion channel 2011 to drive the driving fan disk 202 to rotate. When the driving fan disk 202 rotates, it can drive the rotating disk 301 to rotate through the driving shaft 2022, so that the heat dissipation mechanism 3 can blow air onto the compressor body 1 to achieve the heat dissipation effect. The outside of the outer shell of the compressor body 1 is provided with heat dissipation fins 102, and a number of heat dissipation fins 102 are arranged in a ring shape on the outside of the compressor body 1. The heat dissipation fins 102 on the outside of the compressor body 1 can improve the heat dissipation effect of the compressor body 1 in cooperation with the heat dissipation mechanism 3, accelerate the heat exchange rate between the compressor body 1 and the outside world, and further ensure that the compressor body 1 can always be in the best working state when in use, and the stability is extremely strong.

[0035] Among them, a positioning gear 3021 is provided at one end of the rotating shaft of the heat dissipation fan blade 302, and an adjusting gear 3031 is provided on the top of the adjusting disk 303. The gear teeth of the adjusting gear 3031 and the positioning gear 3021 are meshed for transmission. In use, the use angle of the heat dissipation fan blade 302 can be freely adjusted through the locking column 304. Therefore, when the use angle of the heat dissipation fan blade 302 is changed, the heat dissipation effect generated by the heat dissipation fan blade 302 in the unit rotation rate of the rotating disk 301 (because the kinetic energy of the high-pressure fluid output by the compressor body 1 is fixed, the rotation rate of the rotating disk 301 is also fixed) will also change, and it can be installed and used in different environments. When the locking column 304 is pressed and rotated, the locking gear 3042 will be locked after the locking column 304 is pressed. The locking column 304 enters the avoidance groove 3112 so that the locking column 304 can rotate freely. A synchronization column 3032 is provided on the top of the adjusting disk 303, and the cross-sectional shape of the synchronization column 3032 is a regular polygon. A synchronization groove 3041 is provided inside the locking column 304, and the synchronization column 3032 is inserted into the synchronization groove 3041. When the locking column 304 rotates, the synchronization groove 3041 can drive the adjusting disk 303 to rotate synchronously through the synchronization column 3032, so that when the adjusting disk 303 rotates, the adjusting gear 3031 can drive the heat dissipation fan blades 302 to rotate through the positioning gear 3021, thereby realizing the change of the strength of the heat dissipation effect generated by the heat dissipation fan blades 302 within the unit rotation rate of the rotating disk 301, and the adjustment is convenient, and the flexibility and adaptability are extremely strong.

[0036] The locking pin 3033 is provided inside the synchronous column 3032, and the two ends of the locking pin 3033 are respectively pressed against the inside of the synchronous column 3032 and the locking column 304. In use, when the heat dissipation mechanism 3 is in the reset state, the use angle of the heat dissipation fan blade 302 is fixed, so that the rotating disk 301 can stably provide heat dissipation effect for the compressor body 1 when rotating. In the reset state, a locking gear 3042 is provided at the bottom of the column body of the locking column 304, and a locking control groove 311 is provided inside the rotating disk 301. The locking gear 3042 is plugged into the inside of the locking control groove 311. The locking control groove 311 is composed of a locking tooth groove 3111 and an avoidance groove 3112, and the locking tooth groove 3111 is located at At the top of the avoidance groove 3112, the inner diameter of the avoidance groove 3112 is larger than the outer diameter of the locking gear 3042, so that the locking gear 3042 is inserted into the locking tooth groove 3111 under the action of the locking top spring 3033, so that the locking column 304 cannot rotate, and the cooperation of the synchronization column 3032 and the synchronization groove 3041 makes the use state of the adjustment disk 303 also locked and unable to rotate, so that the cooling fan blade 302 is also unable to rotate under the cooperation of the positioning gear 3021 and the adjustment gear 3031, thereby maintaining the stability of the cooling fan blade 302 during use, and there will be no accidental change in the use angle that will cause the cooling effect to change, and the stability is extremely strong.

[0037] In another embodiment, the drive shaft 2022 is connected to the rotating disk 301 through a gear set, so that the transmission ratio between the drive shaft 2022 and the rotating disk 301 can be changed by changing the gear ratio of the gear set (i.e., the transmission ratio), so that the actual rotation rate and transmission torque of the rotating disk 301 can be controlled according to actual installation and use requirements, thereby further improving the flexibility and adaptability of the device.

[0038] Specific usage and function of this embodiment: In the present invention, when the air conditioner is working, the indoor unit and outdoor unit of the air conditioner belong to the low-pressure or high-pressure area respectively (depending on the working state), and the refrigerant flows from the high-pressure area to the low-pressure area, and is sprayed into the evaporator through the capillary tube, the pressure drops suddenly, and the liquid refrigerant immediately turns into gas, and absorbs a large amount of heat in the air through the heat sink. In this way, the air conditioner compressor keeps working, and the heat at one end of the low-pressure area is continuously absorbed into the refrigerant and then sent to the high-pressure area to be dissipated into the air, which plays a role in regulating the temperature. In the initial stage of installation, it is necessary to adjust the use angle of the heat dissipation fan blade 302 according to the installation environment, so as to adjust the size and strength of the heat dissipation effect of the heat dissipation mechanism 3. The use angle of the heat dissipation fan blade 302 can be freely adjusted through the locking column 304, so that when the use angle of the heat dissipation fan blade 302 is changed, the unit rotation rate of the rotating disk 301 (because the kinetic energy of the high-pressure fluid output by the compressor body 1 is fixed, so the rotation rate of the rotating disk 301 is also fixed) is generated by the heat dissipation fan blade 302. The heat dissipation effect will also change, and it can adapt to installation and use in different environments. When the locking column 304 is pressed and rotated, the locking gear 3042 will enter the inside of the avoidance groove 3112 after the locking column 304 is pressed, so that the locking column 304 can rotate freely. When the locking column 304 rotates, the synchronous groove 3041 can drive the adjustment disk 303 to rotate synchronously through the synchronous column 3032, so that when the adjustment disk 303 rotates, the adjustment gear 3031 can drive the heat dissipation fan blades 302 to rotate through the positioning gear 3021, thereby changing the strength of the heat dissipation effect generated by the heat dissipation fan blades 302 within the unit rotation rate of the rotating disk 301. It can be used after the installation is completed. Under the action of the self-heating component, when the compressor body 1 is working, the high-pressure fluid inside it can act on the driving mechanism 2, so that under the drive of the driving mechanism 2, the self-heating effect of the compressor body 1 can be achieved through the heat dissipation mechanism 3. No additional power drive is required, and the use is flexible and convenient. The heat dissipation efficiency of the heat dissipation mechanism 3 can be freely adjusted, so that it can be adapted to use in different environments, ensuring that the compressor body 1 is always in the best working state. When the compressor body 1 is working, the heat dissipation mechanism 3 can be driven to work through the driving mechanism 2 to achieve the heat dissipation operation of the compressor body 1. When the high-pressure fluid is from After the high-pressure fluid pipe 101 of the compressor body 1 flows out, the high-pressure fluid can drive the fan blades 2021 to drive the driving fan disc 202 to rotate through the conversion channel 2011. When the driving fan disc 202 rotates, it can drive the rotating disc 301 to rotate through the driving shaft 2022, so that the heat dissipation mechanism 3 can blow air onto the compressor body 1 to achieve the heat dissipation effect. At the same time, the heat dissipation fins 102 outside the compressor body 1 can improve the heat dissipation effect of the compressor body 1 and the heat dissipation mechanism 3, further ensuring that the compressor body 1 can always be in the best working state when in use. When the heat dissipation mechanism 3 is in the reset state, the use angle of the heat dissipation fan blades 302 is fixed.Therefore, the rotating disk 301 can stably provide heat dissipation effect for the compressor body 1 when rotating. In the reset state, the locking gear 3042 is inserted into the locking tooth groove 3111 under the action of the locking top spring 3033, so that the locking column 304 cannot rotate. Under the cooperation of the synchronization column 3032 and the synchronization groove 3041, the use state of the adjustment disk 303 is also locked and cannot rotate. Therefore, under the cooperation of the positioning gear 3021 and the adjustment gear 3031, the heat dissipation fan blade 302 cannot rotate either, thereby maintaining the stability of the heat dissipation fan blade 302 when in use, and there will be no phenomenon of changing the heat dissipation effect due to an accidental change in the use angle.
