Description

Technical Field

[0001] The invention relates to the technical field of sand removal equipment, in particular to a bracket and an air conditioner with automatic sand removal function. Background Art

[0002] Due to the special operating environment of desert equipment, especially after a sandstorm, part of the air-conditioning outdoor unit will be covered or invaded by sand and dust; if there is a lot of sand and dust accumulated on the bottom plate of the air-conditioning outdoor unit, when the outdoor unit blades rotate at high speed, the sand and dust disturbed by the airflow will fly inside the air-conditioning outdoor unit, easily hitting and wearing the fan blades, and easily getting stuck in the connection of the fan shaft, thereby reducing the service life of the air-conditioning outdoor unit.

[0003] The sand-discharging air conditioner in the prior art generally has sand-discharging holes at the bottom of the air conditioner outdoor unit. However, in order to better realize the sand-discharging function, this method relies on the rotation of the outdoor unit blades to generate airflow to blow the sand and dust out of the sand-discharging holes. When the air conditioner outdoor unit is not working, the sand-discharging effect is poor, and the setting of the sand-discharging holes makes it easier for sand and dust to enter the air conditioner outdoor unit. Summary of the invention

[0004] The present invention provides a support with an automatic sand discharge function, which can overcome certain defects of the prior art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions, which include:

[0006] A bottom plate, wherein the bottom plate is provided with sand discharge holes;

[0007] A rotating plate, the rotating plate is rotatably disposed at the sand discharge hole through a rotating shaft, the rotating plate has a first position and a second position, when the rotating plate is in the first position, the sand discharge hole is in a closed state, and when the rotating plate is in the second position, the sand discharge hole is in an open state;

[0008] an infrared dust sensor, the infrared dust sensor is used to generate a first detection signal when the dust concentration value inside the air conditioner outdoor unit is higher than a preset reference concentration value, and is also used to generate a second detection signal when the dust concentration value inside the air conditioner outdoor unit is not higher than the preset reference concentration value; and

[0009] The motor is used to drive the rotating shaft to rotate when the first detection signal is generated to realize the movement of the rotating plate to the second position, and is also used to drive the rotating shaft to rotate in the opposite direction when the second detection signal is generated to realize the movement of the rotating plate to the first position.

[0010] In the present invention, through the arrangement of the bottom plate, the rotating plate, the infrared dust sensor, the rotating shaft and the motor, the infrared dust sensor can detect the dust concentration value inside the air-conditioning outdoor unit in real time. When the dust concentration value is too high, the motor can drive the rotating shaft to rotate. Since the rotating shaft is fixedly connected to the rotating plate, the rotation of the rotating shaft can drive the rotating plate to rotate, and the sand discharge hole gradually opens, so that the sand and dust on the rotating plate are discharged along the inclined rotating plate; when the dust concentration value is reduced to a smaller value, the motor drives the rotating shaft to rotate in the opposite direction until the rotating plate is flush with the bottom plate, thereby realizing the closing of the sand discharge hole by the rotating plate; compared with the prior art, the present invention better realizes the automatic detection of sand and dust inside the air-conditioning outdoor unit and the discharge of sand, and the closing when there is no sand and dust inside the air-conditioning outdoor unit, without affecting the normal operation of the air conditioner.

[0011] It is worth noting that the infrared dust sensor is a prior art, and the operator can set the baseline concentration value according to the specific application scenario; in addition, the present invention is not only suitable for installation at the bottom of the sand discharge equipment, but also suitable for inclined installation. However, when installed at an inclined angle, the maximum angle of the rotating plate should be able to enable the sand and dust at the sand discharge hole to be discharged from the sand discharge hole only under the action of gravity.

[0012] Furthermore, the present invention is not only applicable to installation at the bottom where sand discharge equipment is required, but also applicable to inclined installation. However, when the installation is inclined, the maximum angle of the rotating plate should be able to discharge the sand and dust at the sand discharge hole only under the action of gravity.

[0013] Preferably, a signal processing mechanism is provided between the infrared dust sensor and the motor; the signal processing mechanism is used to convert the first detection signal and the second detection signal into a first drive signal capable of driving the motor to rotate and a second drive signal capable of driving the motor to rotate in the opposite direction, respectively.

[0014] By setting the signal processing mechanism in the present invention, the detection signal output by the infrared dust sensor can be converted into a driving signal capable of driving the motor to move, thereby further realizing more timely sand removal.

[0015] Preferably, a transmission mechanism is provided between the rotating shaft and the motor.

[0016] By setting the transmission mechanism in the present invention, it is possible to ensure higher transmission efficiency during the transmission process.

[0017] Preferably, dust covers are provided outside the transmission mechanism and the motor.

[0018] The provision of the dust cover in the present invention can effectively prevent dust from getting stuck in the gap between the motor shaft and the gear, thereby effectively reducing the obstructive effect of dust in the indoor unit of the air conditioner on the transmission mechanism and the motor during operation.

[0019] Preferably, the first detection signal and the second detection signal are both PWM signals.

[0020] Preferably, the signal processing mechanism includes an MCU chip.

[0021] Through the setting of the MCU chip in the present invention, the MCU chip has the characteristic of better real-time response to external signals. When the sensor sends a detection signal, the MCU chip can convert the detection signal into a driving signal that can drive the motor to move in a relatively timely manner, further realizing relatively timely sand removal.

[0022] Preferably, the rotating plate 102 is fixedly connected to the rotating shaft 401, and the rotating shaft 401 is rotatably connected to the bottom plate.

[0023] The present invention also provides an air conditioner, comprising any one of the above-mentioned brackets. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0030] Example 1

[0031] like Figure 1-4 As shown, this embodiment provides a support with automatic sand discharge function, which includes:

[0032] A bottom plate 101, wherein the bottom plate 101 is provided with a sand discharge hole 104;

[0033] The rotating plate 102 is rotatably disposed at the sand discharge hole 104 via a rotating shaft 401. The rotating plate 102 has a first position and a second position. When the rotating plate 102 is in the first position, the sand discharge hole 104 is in a closed state. When the rotating plate 102 is in the second position, the sand discharge hole 104 is in an open state.

[0034] an infrared dust sensor, the infrared dust sensor is used to generate a first detection signal when the dust concentration value inside the air conditioner outdoor unit is higher than a preset reference concentration value, and is also used to generate a second detection signal when the dust concentration value inside the air conditioner outdoor unit is not higher than the preset reference concentration value; and

[0035] The motor is used to drive the rotating shaft 401 to rotate when the first detection signal is generated to realize the movement of the rotating plate 102 to the second position, and is also used to drive the rotating shaft 401 to rotate in the opposite direction when the second detection signal is generated to realize the movement of the rotating plate 102 to the first position.

[0036] In this embodiment, through the arrangement of the base plate 101, the rotating plate 102, the infrared dust sensor, the rotating shaft 401 and the motor, the infrared dust sensor can detect the dust concentration value inside the air conditioner outdoor unit in real time. When the dust concentration value is too high, the motor can drive the rotating shaft 401 to rotate. Since the rotating shaft 401 is fixedly connected to the rotating plate 102, the rotation of the rotating shaft 401 can drive the rotating plate 102 to rotate, and the sand discharge hole 104 gradually opens, so that the sand and dust on the rotating plate 102 are discharged along the inclined rotating plate 102; when the dust concentration value is reduced to a smaller value, the motor drives the rotating shaft 401 to rotate in the opposite direction until the rotating plate 102 is flush with the base plate 101, so that the rotating plate 102 closes the sand discharge hole 104; compared with the prior art, this embodiment better realizes automatic detection of sand and dust inside the air conditioner outdoor unit and discharges sand, and closes when there is no sand and dust, without affecting the normal operation of the air conditioner.

[0037] It is worth noting that the infrared dust sensor is a prior art, and the operator can set the baseline concentration value according to the specific application scenario; in addition, the present embodiment is not only suitable for installation at the bottom of the sand discharge equipment, but also suitable for inclined installation. However, when installed at an inclined angle, the maximum angle at which the rotating plate 102 is opened should enable the sand and dust at the sand discharge hole 104 to be discharged from the sand discharge hole 104 only under the action of gravity.

[0038] Furthermore, this embodiment is not only applicable to installation at the bottom where sand discharge equipment is required, but also applicable to inclined installation. However, when the installation is inclined, the maximum angle of the rotating plate 102 should be able to discharge the sand and dust at the sand discharge hole 104 only under the action of gravity.

[0039] In this embodiment, a signal processing mechanism is provided between the infrared dust sensor and the motor; the signal processing mechanism is used to convert the first detection signal and the second detection signal into a first drive signal capable of driving the motor to rotate and a second drive signal capable of driving the motor to rotate in the opposite direction, respectively.

[0040] By setting the signal processing mechanism in this embodiment, the detection signal output by the infrared dust sensor can be converted into a driving signal that can drive the motor to move, thereby further realizing more timely sand removal.

[0041] In this embodiment, a transmission mechanism is provided between the rotating shaft 401 and the motor.

[0042] By setting the transmission mechanism in this embodiment, it is possible to ensure higher transmission efficiency during the transmission process.

[0043] In this embodiment, dust covers 105 are provided outside the transmission mechanism and the motor.

[0044] By providing the dust cover 105 in this embodiment, it is possible to better prevent dust from getting stuck in the gap between the motor shaft and the gear, thereby better reducing the obstructive effect of dust in the indoor unit of the air conditioner on the transmission mechanism and the motor during operation.

[0045] In this embodiment, the first detection signal and the second detection signal are both PWM signals.

[0046] In this embodiment, the signal processing mechanism includes an MCU chip.

[0047] Through the setting of the MCU chip in this embodiment, the MCU chip has the characteristic of better real-time response to external signals. When the sensor sends a detection signal, the MCU chip can convert the detection signal into a driving signal that can drive the motor to move in a relatively timely manner, further realizing relatively timely sand removal.
