Description

Automatic cleaning device

The present invention relates to a cleaning device, in particular to an automatic cleaning device.

With the changes in the environment and the rapid development of technology, modern people usually install air conditioning equipment in their homes or business premises to maintain the air quality and temperature in their homes or business premises to avoid the rising temperature in summer due to environmental changes.

Among them, the existing air conditioning equipment (such as split air conditioners) includes an outdoor unit and an indoor unit, and the indoor unit has a wind drum to guide the cold air to the air outlet to reduce the ambient temperature. However, after a period of time, suspended particles and dust will accumulate on the wind drum in large quantities, resulting in a decrease in the air volume of the air conditioning equipment and the indoor temperature cannot be effectively reduced. The user needs to regularly dismantle the air conditioning equipment and clean the wind drum, which is very inconvenient. Moreover, if the structure of the air conditioning equipment is more complicated, it is necessary to hire professional cleaning personnel to clean it, resulting in an increase in the overall maintenance cost of the air conditioning equipment.

To solve the above problems, the present invention discloses an automatic cleaning device that can automatically clean the blower, so that users can save the time of disassembling and assembling air-conditioning equipment and the personnel cost of hiring professional cleaning personnel.

To achieve the above-mentioned purpose, an embodiment of the present invention provides an automatic cleaning device, which is arranged in an air conditioning device. The present invention includes an air compressor, a blowing component, a controller and a dust collecting component. The air compressor is arranged in an outdoor unit of the air conditioning device. The air compressor has an air intake part and an air delivery part. The air delivery part is provided with an air delivery valve. The air delivery valve selectively opens the air delivery part. The air compressor inputs external gas through the air intake part and compresses the external gas into a high-pressure gas. The air compressor outputs the high-pressure gas through the air delivery part. The blowing component is arranged in an indoor unit of the air conditioning device and is located on the top side of a wind drum of the indoor unit. The blowing component has a connecting part and a blowing part. The connecting part is connected to the air delivery part so that the blowing part receives the high-pressure gas, and the blowing part is for delivering the high-pressure gas toward the air drum; the controller is coupled to the air compressor, and the controller has a detection part and a control part. The detection part detects a pressure value of the high-pressure gas, and the control part is preset with a pressure standard value. When the pressure value is greater than or equal to the pressure standard value, the control part controls the air delivery valve to open the air delivery part to deliver the high-pressure gas to the blowing part; the dust collecting part is arranged at the bottom side of the air drum, and receives the attachment dropped from the air drum.

Thus, the present invention can automatically clean the air blower through the coordinated air compressor, air blowing component, controller and dust collecting component, so as to save the user the time of disassembling and assembling the air conditioning equipment and the personnel cost of hiring professional cleaning personnel.

Furthermore, since the present invention can clean the wind drum regularly, the damage rate of the air conditioning equipment can be reduced and the overall service life of the air conditioning equipment can be increased.

In order to facilitate the explanation of the central idea of the present invention in the above-mentioned creative content column, a specific embodiment is used for expression. It should be noted that various objects in the embodiment are drawn in proportions suitable for enumeration and description, rather than in proportions of actual elements.

Please refer to FIG. 1 to FIG. 5 , which disclose an automatic cleaning device 100 of an embodiment of the present invention, which is arranged in an air conditioning device 1. The present invention comprises an air compressor 10, a blowing component 20, a controller 30 and a dust collecting component 40. The air conditioning device 1 comprises an outdoor unit 1a and an indoor unit 1b, and the indoor unit 1b has a blower 1c.

The air compressor 10 is provided in the outdoor unit 1a, and has an air inlet 11 and an air delivery part 12. The air inlet 11 is for the air compressor 10 to input external gas, so that the air compressor 10 can compress the external gas into a high-pressure gas; the air delivery part 12 is provided with an air delivery valve 121, and the air delivery valve 121 selectively opens the air delivery part 12. When the air delivery valve 121 opens the air delivery part 12, the air compressor 10 can output the high-pressure gas through the air delivery part 12.

Among them, in the embodiment of the present invention, the air delivery valve 121 normally closes the air delivery part 12 so that the air compressor 10 can accurately compress the external gas into the high-pressure gas; the air compressor 10 is linked with the air-conditioning device 1. When the air-conditioning device 1 starts to operate, the air compressor 10 will start to operate, and when the air-conditioning device 1 stops operating, the air compressor 10 will stop operating.

The blowing member 20 is provided in the indoor unit 1b and is located on the top side of the wind drum 1c. The blowing member 20 has a connecting portion 21 and a blowing portion 22. The connecting portion 21 is connected to the gas delivery portion 12 so that the blowing member 20 receives the high-pressure gas; the blowing portion 22 is used to output the high-pressure gas toward the wind drum 1c, so that the high-pressure gas cleans the wind drum 1c and makes the attached objects on the wind drum 1c fall into the dust collecting member 40.

As shown in FIG. 4 , in the embodiment of the present invention, the blowing portion 22 is flat, and the blowing portion 22 gradually expands in the direction away from the connecting portion 21, so as to effectively increase the area cleaned by the high-pressure gas on the wind drum 1c; as shown in FIG. 4 , in the embodiment of the present invention, the number of the blowing parts 20 is plural, and the blowing parts 20 are arranged at intervals along the axial direction of the wind drum 1c, so as to increase the area cleaned by the high-pressure gas on the wind drum 1c, so that the high-pressure gas can comprehensively clean the wind drum 1c and improve the cleaning efficiency.

The controller 30 is coupled to the air compressor 10 and has a detector 31 and a control component 32. The detector 31 detects a pressure value of the high-pressure gas and outputs the pressure value to the control component 32; the control component 32 is preset with a pressure standard value. When the pressure value is greater than or equal to the pressure standard value, the control component 32 controls the gas delivery valve 121 to open the gas delivery part 12 to output the high-pressure gas to the blowing component 20, so that the blowing component 20 can output the high-pressure gas and clean the air drum 1c.

As shown in FIG. 1 to FIG. 4 , in the embodiment of the present invention, the controller 30 further includes a timing element 33. The timing element 33 is preset with an interval time data 331. The timing element 33 controls the air compressor 10 to compress the external gas into the high-pressure gas every time an interval time passes according to the interval time data 331, so as to perform the cleaning work of the air blower 1c by the high-pressure gas in the subsequent process. Among them, the interval time data 331 can be changed by the user according to the installation environment of the air-conditioning equipment 1. For example, when the air-conditioning equipment 1 is installed near an industrial area, because there are more suspended particles and dust in the external environment, the user can shorten the interval time of the interval time data 331 to increase the cleaning frequency of the present invention to maintain the cleanliness of the wind drum 1c.

The dust collecting member 40 is disposed at the bottom of the wind drum 1c to receive the attached objects dropped from the wind drum 1c after being cleaned by the high-pressure gas. As shown in FIG. 4 , in the embodiment of the present invention, the dust collecting member 40 is generally in the shape of a groove to prevent the attached objects from escaping from the dust collecting member 40 .

As shown in FIG. 4 , in other embodiments of the present invention, the dust collecting part 40 has a storage space 41, and the storage space 41 can store the attached objects, so as to facilitate the subsequent user to remove the attached objects. The width W1 of the storage space 41 along the horizontal direction is greater than the width W2 of the wind drum 1c along the horizontal direction, so that the dust collecting part 40 can effectively receive the attached objects and prevent the attached objects from escaping from the dust collecting part 40.

As shown in FIG. 2 and FIG. 5 , in other embodiments of the present invention, there is further included an exhaust member 50 , which is disposed at the outdoor unit 1 a , and is connected to the dust collecting member 40 to extract the attached matter from the storage space 41 . As shown in FIG. 2 and FIG. 5 , an exhaust portion 51 and an exhaust portion 52 are provided at both ends of the exhaust member 50, an exhaust hole 42 is provided in the storage space 41, the exhaust portion 51 is connected to the outside environment, and the exhaust portion 52 is connected to the exhaust hole 42. The exhaust member 50 discharges the attachments from the storage space 41 to the outside environment through the exhaust hole 42, the exhaust portion 52 and the exhaust portion 51 in sequence, so that the exhaust member 50 can directly remove the attachments from the indoor unit 1b at the first time when the attachments fall, thereby reducing the probability of the attachments remaining in the indoor unit 1b and keeping the interior of the indoor unit 1b clean. Furthermore, the number of the exhaust holes 42 can be increased according to user needs to increase the discharge speed of the attachments.

Thus, the present invention can automatically clean the wind drum 1c through the coordinated air compressor 10, the blowing member 20, the controller 30 and the dust collecting member 40, so as to save the user the time of disassembling and assembling the air conditioning device 1 and the personnel cost of hiring professional cleaning personnel. Moreover, since the present invention can clean the wind drum 1c regularly, the damage speed of the air conditioning device 1 can be reduced, and the overall service life of the air conditioning device 1 can be increased.
