[0031] Embodiment 1

[0032] Figure 1 A structural schematic diagram of a precision air conditioner is provided for the first embodiment of the present invention. The precision air conditioner in this embodiment can avoid the problem of air conditioner failure caused by accumulation of debris at the air outlet.

[0033] like Figure 1 As shown, the precision air conditioner 100 provided in the first embodiment of the present invention specifically includes: a precision air conditioner body (including an indoor unit and an outdoor unit 101) and a dustproof device 102, wherein the dustproof device 102 includes a dust cover frame 103, a motor 104 and a driving connecting rod 105; wherein:

[0034] The dust cover frame 103 includes a dust cover 106, an outdoor unit frame 107 and a connecting component 108; the dust cover 106 is connected to the outdoor unit frame 107 through the connecting component 108 and the driving connecting rod 105 respectively; the dustproof device 102 is arranged on the outside of the outdoor unit 101 of the precision air conditioner, and the dust cover 106 is opposite to the air outlet of the fan of the outdoor unit; the driving connecting rod 105 is used to adjust the angle between the dust cover 106 and the plane where the fan of the outdoor unit is located; the motor is used to provide kinetic energy to the driving connecting rod 105.

[0035] In this embodiment, the size of the outdoor unit frame is larger than the size of the precision air conditioner outdoor unit, and the dustproof device is covered on the outside of the precision air conditioner outdoor unit. The dust cover facing the outdoor unit air outlet can block debris for the outdoor unit while ensuring the ventilation volume of the air outlet. The driving connecting rod arranged between the dust cover and the outdoor unit frame can adjust the angle between the dust cover and the plane where the fan of the outdoor unit is located. By increasing the angle, the debris on the dust cover can be removed. For example, when the outdoor unit air outlet is directly above, if the angle is adjusted to 90 degrees, the dust cover is perpendicular to the horizontal plane, and the debris on the dust cover will slide off the dust cover due to gravity. Among them, when the outdoor unit air outlet is directly above, a dust shield can be provided on the side of the outdoor unit frame.

[0036] The precision air conditioner provided by the embodiment of the present invention includes a precision air conditioner body and a dustproof device. The dust cover arranged on the dust cover frame outside the outdoor unit of the precision air conditioner and facing the air outlet of the fan can block debris for the air outlet to prevent the precision air conditioner from malfunctioning due to the accumulation of debris at the air outlet. A driving connecting rod is arranged between the dust cover and the outdoor unit frame. By adjusting the angle between the dust cover and the plane where the fan of the outdoor unit is located, gravity is used to automatically remove debris on the dust cover, further ensuring good ventilation at the air outlet of the outdoor unit of the precision air conditioner.

[0037] Embodiment 2

[0038] The precision air conditioner of the embodiment of the present invention is further optimized on the basis of the above embodiment, and provides specific details of the precision air conditioner.

[0039] Optionally, the dust prevention device further includes a control unit and a sensor arranged at the fan outlet of the outdoor unit of the precision air conditioner; the sensor is used to measure the wind pressure at the fan outlet; the control unit is used to send an angle control instruction to the drive connecting rod according to the wind pressure, wherein the angle control instruction is used to instruct the drive connecting rod to adjust the angle between the dust cover and the plane where the fan of the outdoor unit is located. The advantage of this arrangement is that the congestion of the dust cover is accurately detected by the sensor, and automatic dust removal is achieved by sending an angle control instruction to the drive connecting rod according to the congestion.

[0040] Specifically, when the control unit determines that the wind pressure collected by the sensor is too small, it can send an angle increase control instruction to the driving connecting rod to remove the debris on the dust cover by opening the dust cover.

[0041] Further, the dustproof device also includes a memory card; when the wind pressure is greater than a preset value, the driving connecting rod adjusts the angle between the dust cover and the plane where the fan of the outdoor unit is located to a first preset angle, wherein the preset value is determined according to the mapping relationship between different wind pressures at the fan outlet and air volume and power stored in the memory card; when the wind pressure is less than or equal to the preset value, the driving connecting rod adjusts the angle between the dust cover and the plane where the fan of the outdoor unit is located to a second preset angle and maintains the first preset duration; after the first preset duration, the blades of the fan rotate in a preset direction for a second preset duration to blow off the objects on the dust cover; after the second preset duration, the driving connecting rod adjusts the angle between the dust cover and the plane where the fan is located to the first preset angle, wherein the first preset angle is less than the second preset angle. The advantage of this arrangement is that when the wind pressure at the outdoor unit outlet is too small, various foreign objects on the dust cover can be removed by changing the angle between the dust cover and the fan and driving the fan to rotate.

[0042] Specifically, Figure 2 This is a closed schematic diagram of a precision air conditioner dust cover. Figure 2 21 is a dust cover, 22 is an outdoor unit of the precision air conditioner, and 23 is a frame of the outdoor unit. Figure 3 This is a schematic diagram of opening a dust cover of a precision air conditioner. Figure 3 31 is a dust cover, 32 is an outdoor unit of the precision air conditioner, and 33 is a frame of the outdoor unit. The control unit can determine a preset value based on the mapping relationship between different wind pressures at the fan outlet and the air volume and power stored in the memory card. For example, the lower limit of the normal wind pressure under the current air volume and power is determined according to the mapping relationship, and then the product of the lower limit and the preset margin coefficient is determined as the preset value. If the control unit determines that the current wind pressure is greater than the preset value, a first angle control instruction is sent to the drive connecting rod so that the drive connecting rod adjusts the angle between the dust cover and the plane where the fan of the outdoor unit is located to a first preset angle, such as Figure 2 If the control unit determines that the current wind pressure is less than or equal to the preset value, it sends a second angle control instruction to the driving connecting rod, so that the driving connecting rod adjusts the angle between the dust cover and the plane where the fan of the outdoor unit is located to a second preset angle, such as Figure 3 The fan blades can rotate in a preset direction for a second preset time, such as 30 seconds, to utilize the positive pressure to the outside world to blow off objects on the dust cover, such as dust and small foreign objects. After the second preset time, the control unit sends a first angle control instruction to the drive connecting rod, so that the drive connecting rod adjusts the angle between the dust cover and the plane where the fan of the outdoor unit is located to the first preset angle.

[0043] Optionally, the precision air conditioner and the electric motor are powered independently.

[0044] Specifically, by independently powering the outdoor unit and the motor of the precision air conditioner, it is ensured that when the outdoor unit is powered off, the motor can still operate normally, thereby further ensuring the dust removal effect.

[0045] The precision air conditioner provided in the embodiment of the present invention utilizes a sensor to accurately detect the congestion condition of the dust cover, and sends an angle control instruction to the driving connecting rod according to the congestion condition. When the wind pressure at the outdoor unit outlet is too small, the angle between the dust cover and the fan is changed and the fan is driven to rotate to remove various foreign objects on the dust cover, thereby realizing automatic dust removal and ensuring the normal operation of the precision air conditioner.

[0046] Embodiment 3

[0047] Figure 4 A flow chart of a dust removal method for an outdoor unit of a precision air conditioner is provided for the third embodiment of the present invention. This embodiment can be applicable to the case of dust removal for a precision air conditioner and is applied to the precision air conditioner described in the above embodiment. The method can be executed by the dust removal system of the outdoor unit of the precision air conditioner, and the dust removal system of the outdoor unit of the precision air conditioner can be configured in the precision air conditioner described in the above embodiment.

[0048] like Figure 4 As shown, the dust removal method for the outdoor unit of a precision air conditioner provided in the third embodiment of the present invention specifically includes the following steps:

[0049] S301. Obtain target information of a fan of an outdoor unit of the precision air conditioner, wherein the target information includes a current air volume, a current power and a wind pressure at an air outlet of the fan of the outdoor unit, and the current air volume and the current power are measured by sensors built into the precision air conditioner.

[0050] In this embodiment, the wind pressure at the air outlet can be obtained by using a sensor at the outdoor unit of the precision air conditioner, and the current air volume and current power of the fan of the outdoor unit can be obtained by using a built-in sensor of the precision air conditioner.

[0051] S302. Control the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located according to the target information and the target mapping relationship, wherein the target mapping relationship includes the mapping relationship between the wind pressure at the air outlet of the fan and the air volume and power.

[0052] Specifically, the lower limit of normal wind pressure under the current air volume and current power can be determined according to the target mapping relationship, and then the angle between the dust cover and the plane where the fan is located can be controlled by comparing the wind pressure at the air outlet with the lower limit of normal wind pressure. For example, when the air outlet of the fan is upward, if the wind pressure at the air outlet is less than the lower limit of normal wind pressure, the angle can be increased to remove objects on the dust cover.

[0053] The dust removal method for the outdoor unit of a precision air conditioner provided in an embodiment of the present invention can accurately evaluate whether the precision air conditioner needs dust removal based on the current air volume, current power and wind pressure at the air outlet of the fan of the precision air conditioner. When dust removal is needed, the driving connecting rod provided between the dust cover and the outdoor unit frame can be used to automatically remove debris on the dust cover by adjusting the angle between the dust cover and the plane where the fan of the outdoor unit is located, thereby further ensuring good ventilation at the air outlet of the outdoor unit of the precision air conditioner.

[0054] Optionally, before controlling the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located according to the target information and the target mapping relationship, it also includes: performing curve fitting on the mapping relationship between the wind pressure at the fan outlet and the air volume and power to obtain a fitting function, and determining the product of the fitting function and the margin coefficient as a dirty and blocked wind pressure function; wherein, controlling the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located according to the target information and the target mapping relationship includes: inputting the current air volume and the current power into the dirty and blocked wind pressure function to obtain a dirty and blocked wind pressure threshold, and controlling the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located according to the dirty and blocked wind pressure threshold and the wind pressure at the current air outlet. The advantage of such a setting is that the dirty and blocked wind pressure threshold is reasonably determined by using the mapping relationship and the margin coefficient, and the angle between the dust cover and the fan is quickly and accurately controlled by using the threshold to achieve automatic dust removal on the dust cover.

[0055] Exemplarily, the dirty and blocked wind pressure function can be expressed as:

[0056] p=(1-X)*Prs(q,Pow),Prsmin <p<Prsmax

[0057] Among them, (1-X) is the margin coefficient, p is the dirty blocking wind pressure function value, which is the dirty blocking wind pressure threshold. Prs(x, y) is the fitting function, q is the fan air volume, and Pow is the fan power. Prsmin is the minimum wind pressure value, and Prsmax is the maximum wind pressure value. Prsmin and Prsmax are determined according to the model and working conditions of the fan.

[0060] Optionally, the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located is controlled according to the dirty blocking wind pressure threshold and the wind pressure at the current air outlet, including: if the wind pressure at the current air outlet is greater than the dirty blocking wind pressure threshold, the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located is controlled to be a first angle; if the wind pressure at the current air outlet is less than or equal to the dirty blocking wind pressure threshold, the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located is controlled to be a second angle and maintained for a first duration; after the first duration, the blades of the fan are controlled to rotate in a preset direction for a second duration to blow off the objects on the dust cover, and after the second duration, the angle between the dust cover and the plane where the fan is located is controlled to be the first angle, wherein the first angle is less than the second angle. The advantage of such a setting is that large and small foreign objects on the dust cover can be automatically removed by utilizing the fan of the precision air conditioner and changing the angle between the dust cover and the fan.

[0061] like Figure 5 As shown, a dust removal method for an outdoor unit of a precision air conditioner provided by a fourth embodiment of the present invention specifically includes the following steps:

[0062] S401. Obtain target information of a fan of an outdoor unit of the precision air conditioner, wherein the target information includes a current air volume, a current power and a wind pressure at an air outlet of the fan of the outdoor unit, and the current air volume and the current power are measured by sensors built into the precision air conditioner.

[0063] S402, performing curve fitting on the mapping relationship between the wind pressure at the wind outlet, the air volume and the power of the fan to obtain a fitting function, and determining the product of the fitting function and the margin coefficient as the dirty and blocked wind pressure function.

[0064] S403: Input the current air volume and the current power into the dirty and blocked wind pressure function to obtain a dirty and blocked wind pressure threshold.

[0065] S404, determine whether the wind pressure at the current air outlet is greater than the dirty and blocked wind pressure threshold, if so, execute step 405, if not, execute step 406.

[0066] S405. Control the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located to be a first angle.

[0067] Exemplarily, the first angle may be 0 degrees.

[0068] S406. Control the angle between the dust cover in the dustproof device of the precision air conditioner and the plane where the fan is located to be a second angle and maintain it for a first time length.

[0069] Specifically, the second angle may be 90 degrees, and the first duration may be 5 seconds. The dust cover is transformed into a dumping posture by controlling the included angle to be the second angle, so that the large foreign objects on the dust cover are cleaned by the dead weight of the foreign objects.

[0070] S407. After the first duration, control the blades of the fan to rotate in a preset direction for a second duration to blow off objects on the dust cover, and after the second duration, control the angle between the dust cover and the plane where the fan is located to be the first angle, wherein the first angle is smaller than the second angle.

[0071] Exemplarily, the second duration may be 30 seconds.

[0072] The dust removal method for the outdoor unit of a precision air conditioner provided in an embodiment of the present invention realizes automatic removal of large and small foreign objects on the dust cover by utilizing the fan of the precision air conditioner and changing the angle between the dust cover and the fan, thereby improving the utilization efficiency of the precision air conditioner and reducing the operation and maintenance costs of the unit.
