Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for an outdoor unit of a central air conditioner. Background Art

[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from traditional refrigerant air conditioning. It centrally processes air to meet comfort requirements and uses the principle of liquid vaporization refrigeration to provide the required cooling for the air conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the heating and cooling loads of the indoor environment.

[0003] A Chinese utility model patent with publication number CN213983803U discloses a central air conditioner outdoor unit heat dissipation device, including a central air conditioner outdoor unit body, a protective shell detachably connected to the outer side of the central air conditioner outdoor unit body, a movable groove is provided inside the protective shell, a fixing hole is provided inside the pullable protective plate, a clamping plate is fixedly connected to the outer side of the pullable protective plate, an electric telescopic rod is fixedly connected to the inside of the protective shell, a heat dissipation fan is fixedly connected to the inside of the protective shell, a metal heat dissipation strip is fixedly connected to the inside of the protective shell, a first vent is provided inside the protective shell, a second vent is provided inside the pullable protective plate, and a temperature sensor is fixedly installed inside the protective shell.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device dissipates heat from the central air conditioner outdoor unit body through the first vent and the second vent set on the protective shell. However, after the central air conditioner outdoor unit body has been used for a period of time, a large amount of impurities are easily attached to the inner walls of the first vent and the second vent. At this time, the staff needs to clean the first vent and the second vent. However, since it is located outdoors, it is difficult for the staff to clean it. If the staff directly sprays water, the water is easy to contact the central air conditioner outdoor unit body through the first vent and the second vent, which can easily cause damage to the central air conditioner outdoor unit body. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a heat dissipation device for an outdoor unit of a central air conditioner.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a central air-conditioning outdoor unit heat dissipation device, including a device body, two opposite side walls of the device body are provided with vents, a first connecting groove is opened on the inner top wall of the device body, a first rotating groove is opened on the inner wall of the first connecting groove, a second connecting groove is opened on the inner bottom wall of the device body, a second rotating groove is opened on the inner wall of the second connecting groove, and a closing component for cleaning and closing the vents is provided on the device body.

[0007] By adopting the above technical solution, after the vent has been used for a period of time, a large amount of impurities are easily attached to the inner wall of the vent, and the staff needs to clean the vent. At this time, the staff needs to start the closing component to close the vent. Furthermore, the staff only needs to spray cleaning liquid on the vent to clean the impurities. In this process, the closing component blocks the cleaning liquid, thereby reducing the probability of damage to the device body.

[0008] Furthermore, the closing assembly includes a first rotating rod rotatably arranged in a first rotating groove, a connecting belt with one end wrapped around a side wall of the first rotating rod, a fixing rod fixed to a bottom surface of the connecting belt, a fixing belt fixed to a bottom surface of the fixing rod, a second rotating rod rotatably arranged in a second rotating groove, and a driving device arranged on the device body for driving the fixing belt, wherein the other end of the fixing belt is wrapped around the second rotating rod.

[0009] Furthermore, the driving device includes a first motor fixed on the side wall of the device body and a second motor fixed on the side wall of the device body, the output shaft of the first motor is fixed to the first rotating rod, and the output shaft of the second motor is fixed to the second rotating rod.

[0010] By adopting the above technical solution, when the staff needs to close the vent, the staff needs to start the first motor, so that the connecting belt can be gradually wound around the first rotating rod, so that the fixing belt moves upward under the action of the connecting belt, and then the upper surface of the fixing rod is pressed against the inner top wall of the device body, so that the fixing rod closes the first connecting groove and the fixing belt blocks the cleaning liquid. Then, when the staff finishes cleaning, the staff only needs to turn off the first motor and start the second motor to rotate the second rotating rod, so that the fixing belt is gradually wound around the second rotating rod, so that the connecting belt moves downward. Then, when the bottom surface of the fixing rod is pressed against the inner bottom wall of the device body, the staff only needs to turn off the second motor to keep the fixing rod stable.

[0011] Furthermore, a water baffle is fixed on the inner bottom wall of the device body to reduce the probability of water flowing into the second connecting groove.

[0012] By adopting the above technical solution, when the upper surface of the fixing rod is pressed against the inner top wall of the device body, the water baffle blocks the cleaning liquid, thereby reducing the probability of the cleaning liquid entering the second connecting groove, which is beneficial to prolonging the service life of the device body.

[0013] Furthermore, the first rotating rod includes a first rotating rod fixed to the first motor output shaft and a rotating block rotatably arranged on the first rotating rod, and the upper end of the connecting belt is wound around the rotating block.

[0014] Furthermore, the second rotating rod includes a second rotating rod fixed to the second motor output shaft and an annular rod rotatably arranged on the second rotating rod, and the lower end of the fixing belt is wound around the annular rod.

[0015] By adopting the above technical solution, when the staff starts the first motor, the output shaft of the first motor rotates. Since the rotation resistance between the first rotating rod and the rotating block is large, the first rotating rod and the rotating block rotate along with the output shaft of the first motor. Subsequently, when the upper surface of the fixed rod is pressed against the inner top wall of the device body, the fixed rod cannot move further, so that the rotating block stops rotating. At this time, the force between the first rotating rod and the rotating block increases rapidly, so that the first rotating rod and the rotating block rotate relative to each other, thereby reducing the probability of the first motor being overheated and damaged.

[0016] When the staff starts the second motor, the output shaft of the second motor rotates. Since the rotation resistance between the second rotating rod and the annular rod is large, the second rotating rod and the annular rod rotate along with the output shaft of the second motor. Subsequently, when the bottom surface of the fixed rod is pressed against the inner bottom wall of the device body, the fixed rod cannot move further, so that the annular rod stops rotating. The force between the second rotating rod and the annular rod increases rapidly, so that the second rotating rod and the annular rod rotate relative to each other, thereby reducing the probability of the second motor being overheated and damaged.

[0017] Furthermore, a control switch is provided on the bottom surface of the fixing rod, and the control switch is electrically connected to the second motor.

[0018] By adopting the above technical solution, when the bottom surface of the fixing rod is pressed against the inner bottom wall of the device body, the control switch is pressed against the inner bottom wall of the device body, thereby triggering the control switch, and then the second motor is automatically disconnected, thereby reducing the operating difficulty of the staff.

[0019] Furthermore, a drainage groove is formed through the inner bottom wall of the device body.

[0020] By adopting the above technical solution, when the staff cleans the vent, the excess cleaning liquid is discharged through the drain groove, thereby further reducing the probability of the cleaning liquid causing damage to the device body.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, after the vent has been used for a period of time, a large amount of impurities are easily attached to the inner wall of the vent, and the staff needs to clean the vent. At this time, the staff needs to start the sealing component to seal the vent. Furthermore, the staff only needs to spray cleaning liquid on the vent to allow the cleaning liquid to clean the impurities. In this process, the sealing component blocks the cleaning liquid, thereby reducing the probability of damage to the main body of the device;

[0023] 2. In the present application, when the staff needs to close the vent, the staff needs to start the first motor so that the connecting belt can be gradually wound around the first rotating rod, so that the fixing belt moves upward under the action of the connecting belt, and then the upper surface of the fixing rod is pressed against the inner top wall of the device body, so that the fixing rod closes the first connecting groove and the fixing belt blocks the cleaning liquid. Then, when the staff has finished cleaning, the staff only needs to turn off the first motor and start the second motor to rotate the second rotating rod, so that the fixing belt is gradually wound around the second rotating rod, so that the connecting belt moves downward. Then, when the bottom surface of the fixing rod is pressed against the inner bottom wall of the device body, the staff only needs to turn off the second motor to keep the fixing rod stable;

[0024] 3. In the present application, when the staff starts the first motor, the output shaft of the first motor rotates. Since the rotation resistance between the first rotating rod and the rotating block is relatively large, the first rotating rod and the rotating block rotate along with the output shaft of the first motor. Subsequently, when the upper surface of the fixed rod is pressed against the inner top wall of the device body, the fixed rod cannot move further, so that the rotating block stops rotating. At this time, the force between the first rotating rod and the rotating block increases rapidly, so that the first rotating rod and the rotating block rotate relative to each other, thereby reducing the probability of the first motor being overheated and damaged.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-3 As shown, the embodiment of the present application discloses a heat dissipation device for an outdoor unit of a central air conditioner, comprising a device body 1, a vent 11, a sealing component 4, a water baffle 6, and a control switch 7. Two vents 11 are provided and are respectively arranged on two opposite side walls of the device body 1, so as to improve the heat dissipation effect of the device body 1.

[0031] A first connecting groove 2 is provided on the inner top wall of the device body 1, a first rotating groove 21 is provided on the inner wall of the first connecting groove 2, a second connecting groove 3 is provided on the inner bottom wall of the device body 1, and a second rotating groove 31 is provided on the inner wall of the second connecting groove 3. A closing component 4 is arranged on the device body 1, and is used to clean and close the vent 11. The closing component 4 includes a first rotating rod 41, a connecting belt 42, a fixing rod 43, a fixing belt 44, a second rotating rod 45, and a driving device 5. The first rotating rod 41 is rotatably arranged in the first rotating groove 21, and the first rotating rod 41 includes a first rotating rod 411 and a rotating block 412. The first rotating rod 411 is a round rod-shaped structure, and the first rotating rod 411 and the output shaft of the first motor 51 are fixed to each other. The rotating block 412 is a block-shaped structure with a circular cross section, and the rotating block 412 is rotatably arranged on the first rotating rod 411, and the upper end of the connecting belt 42 is wound around the rotating block 412.

[0032] The second rotating rod 45 is rotatably disposed in the second rotating groove 31, and includes a second rotating rod 451 and an annular rod 452. The second rotating rod 451 is a round rod-shaped structure, and the second rotating rod 451 and the output shaft of the second motor 52 are fixed to each other. The annular rod 452 is a rod-shaped structure with a circular cross section, and the annular rod 452 is rotatably disposed on the second rotating rod 451, and the lower end of the fixing belt 44 is wound around the annular rod 452.

[0033] When the staff starts the first motor 51, the output shaft of the first motor 51 rotates. Since the rotation resistance between the first rotating rod 411 and the rotating block 412 is large, the first rotating rod 411 and the rotating block 412 rotate along with the output shaft of the first motor 51. Subsequently, when the upper surface of the fixed rod 43 is pressed against the inner top wall of the device body 1, the fixed rod 43 cannot move further, so that the rotating block 412 stops rotating. At this time, the acting force between the first rotating rod 411 and the rotating block 412 increases rapidly, so that the first rotating rod 411 and the rotating block 412 rotate relative to each other, thereby reducing the probability of the first motor 51 being overheated and damaged.

[0034] When the staff starts the second motor 52, the output shaft of the second motor 52 rotates. Since the rotation resistance between the second rotating rod 451 and the annular rod 452 is large, the second rotating rod 451 and the annular rod 452 rotate along with the output shaft of the second motor 52. Subsequently, when the bottom surface of the fixed rod 43 is pressed against the inner bottom wall of the device body 1, the fixed rod 43 cannot move further, so that the annular rod 452 stops rotating. The force between the second rotating rod 451 and the annular rod 452 increases rapidly, so that the second rotating rod 451 and the annular rod 452 rotate relative to each other, thereby reducing the probability of the second motor 52 being overheated and damaged.

[0035] One end of the connecting belt 42 is wound around the side wall of the first rotating rod 41. The fixing rod 43 is a rectangular rod-shaped structure, and the fixing rod 43 is fixed to the bottom surface of the connecting belt 42. The fixing belt 44 is a belt-shaped structure, and the fixing belt 44 is fixed to the bottom surface of the fixing rod 43.

[0036] The driving device 5 is arranged on the device body 1, and is used to drive the fixing belt 44. The driving device 5 includes a first motor 51 and a second motor 52. The first motor 51 is fixed on the side wall of the device body 1, and the output shaft of the first motor 51 is fixed to the first rotating rod 41. The second motor 52 is fixed on the side wall of the device body 1, and the output shaft of the second motor 52 is fixed to the second rotating rod 45.

[0037] When the staff needs to close the vent 11, the staff needs to start the first motor 51, so that the connecting belt 42 can be gradually wound around the first rotating rod 41, so that the fixing belt 44 moves upward under the action of the connecting belt 42, and then the upper surface of the fixing rod 43 is pressed against the inner top wall of the device body 1, so that the fixing rod 43 closes the first connecting groove 2, and the fixing belt 44 blocks the cleaning liquid. Then, when the staff has finished cleaning, the staff only needs to turn off the first motor 51 and start the second motor 52, so that the second rotating rod 45 can rotate, so that the fixing belt 44 is gradually wound around the second rotating rod 45, so that the connecting belt 42 moves downward. Then, when the bottom surface of the fixing rod 43 is pressed against the inner bottom wall of the device body 1, the staff only needs to turn off the second motor 52 to keep the fixing rod 43 stable.

[0038] The water baffle 6 is a rectangular plate-shaped structure, and the water baffle 6 is fixed on the inner bottom wall of the device body 1, and is used to reduce the probability of water entering the second connecting groove 3. When the upper surface of the fixing rod 43 is pressed against the inner top wall of the device body 1, the water baffle 6 blocks the cleaning liquid, thereby reducing the probability of the cleaning liquid entering the second connecting groove 3, which is beneficial to prolonging the service life of the device body 1.

[0039] The control switch 7 is arranged on the bottom surface of the fixing rod 43, and the control switch 7 is electrically connected to the second motor 52. When the bottom surface of the fixing rod 43 is pressed against the inner bottom wall of the device body 1, the control switch 7 is pressed against the inner bottom wall of the device body 1, thereby triggering the control switch 7, and then automatically disconnecting the second motor 52, thereby reducing the difficulty of operation for the staff.

[0040] In order to reduce the probability of the cleaning liquid damaging the device body 1, a drainage groove 8 is provided through the inner bottom wall of the device body 1. When the staff cleans the vent 11, the excess cleaning liquid is discharged through the drainage groove 8, thereby further reducing the probability of the cleaning liquid damaging the device body 1.

[0041] The use principle of a central air conditioner outdoor unit heat dissipation device in this embodiment is as follows: after the vent 11 has been used for a period of time, a large amount of impurities are easily attached to the inner wall of the vent 11, and the staff needs to clean the vent 11. At this time, the staff needs to start the closing component 4 to close the vent 11. Further, the staff only needs to spray cleaning liquid on the vent 11, and the cleaning liquid can clean the impurities. In this process, the closing component 4 blocks the cleaning liquid, thereby reducing the probability of damage to the device body 1.
