Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-4, the invention provides an indoor unit of an alternating current duct machine, which comprises a shell 1, an evaporator 2, a water pan 5, a fan 3, an alternating current motor 4, a lifting water baffle 6 and a control module; the shell 1 is provided with a mounting cavity 11, and further comprises an air inlet 12 and an air outlet 13 which are communicated with the mounting cavity 11; the evaporator 2 is arranged in the mounting cavity 11 and is positioned at the air inlet 12; the water pan 5 is arranged in the mounting cavity 11 and is positioned below the evaporator 2; the fan 3 is arranged in the mounting cavity 11 and is positioned at the air outlet 13; the alternating current motor 4 is arranged in the mounting cavity 11 and is in transmission connection with the fan 3; the lifting water baffle 6 comprises a water baffle 61 and a plate lifting mechanism 62; the control module is electrically connected with the lifting mechanism and is in communication connection with the alternating current motor 4; the water baffle 61 is wholly or partially arranged in the mounting cavity 11 and positioned between the water receiving disc 5 and the fan 3, the upper end of the water baffle 61 at least exceeds the water receiving disc 5 by a preset height in the upward direction, and the rising height of the water baffle 61 is set to be zero when the upper end of the water baffle 61 exceeds the water receiving disc 5 by the preset height in the upward direction; the plate lifting mechanism 62 is in transmission connection with the water baffle 61, and the control module controls the plate lifting mechanism 62 to drive the water baffle 61 to lift according to the working current or power of the alternating current motor 4.
Specifically, when the rising height of the water baffle 61 is zero, and the current static pressure of the fan 3 reaches the rated static pressure, because the water baffle 61 has a preset height, the water blowing phenomenon can not be caused, the current static pressure of the fan 3 can be judged to reach the rated static pressure through the working current or power of the alternating current motor 4, when the working current or power is larger than the preset value, the actual static pressure value of the external air pipe pipeline of the fan 3 is smaller than the rated static pressure value, at the moment, the actual air volume of the fan 3 is larger than the rated air volume, may cause the condensed water to be blown out of the drip tray 5 due to an excessive wind speed, and by appropriately raising the water guard 61, the water in the water pan 5 can be blocked to prevent water blowing, the rising height of the water baffle 61 is realized by a regular control plate lifting mechanism 62 preset in the control module, and the refrigeration cannot be influenced because the fan 3 is properly blocked by the water baffle 61 due to overlarge wind speed; when the working current or power is equal to a preset value, the actual static pressure value of the external air pipe pipeline of the fan 3 is equal to the rated static pressure value, and only if the rising height of the water baffle 61 is zero, the fan 3 can normally work and does not generate water blowing; when the working current or power is smaller than the preset value, the actual static pressure value of the external air pipe pipeline of the fan 3 is larger than the rated static pressure value, at the moment, the actual air volume of the fan 3 is smaller than the rated air volume, the rising height of the water baffle 61 is zero, and the fan 3 can normally work without blowing water; when heating, no condensed water exists in the water receiving tray 5, so that the water baffle 61 is not required to block the condensed water, the rising height of the water baffle 61 is zero, and the water baffle 61 does not influence heating. By automatically controlling the height of the water baffle 61, on the basis of preventing the water blowing effect according to the actual condition, the wind resistance of the water baffle 61 is reduced as much as possible, and the influence of the water baffle 61 on the cooling and heating effects of the indoor unit of the alternating-current air duct machine is reduced.

Further, in some embodiments, the drive mechanism includes a drive gear and a drive rack; the transmission gear is fixedly connected with an output shaft of the servo motor; the driving rack is fixedly connected with the water baffle 61 along the height direction and meshed with the driving gear. The servo motor drives the transmission gear to drive the transmission rack, so that the rising height of the water baffle 61 is adjusted.
Referring to fig. 3, the present invention further provides a method for controlling a water guard, including the steps of:
s1, when the control module enters a water baffle control mode, acquiring the current working parameter value of the alternating current motor 4;
s2, comparing the current working parameter value with a preset parameter value;
s3, when the current working parameter value is larger than the preset parameter value, proportionally controlling the rising height of the water baffle 61 according to a preset rule, wherein the maximum value of the rising height is H0;
and S4, when the current working parameter value is less than or equal to the preset parameter value, controlling the rising height of the water baffle 61 to be zero.
In the step S1, the water baffle control mode is started during cooling, and in some embodiments, the amount of water in the water receiving tray 5 may be increased as a determination condition, for example, when the water in the water receiving tray 5 reaches a set height, the water baffle control mode is entered to achieve the power saving effect; the current operating parameter value of the ac motor 4 is the current operating current I1 or the current operating power P1 of the ac motor 4.
In the step S2, the preset parameter value is the rated working current I2 or the rated working power P2, and when the preset parameter value is the rated working current I2, the current working current I1 is compared with the preset rated working current I2; when the preset parameter value is the rated working power P2, comparing the current working power P1 with the preset rated working power P2; specifically according to factory settings.
In the step S3, when the current operating parameter value is greater than the preset parameter value, it represents that the actual static pressure value of the external air pipe of the fan 3 is less than the rated static pressure value, and at this time, the actual air volume of the fan 3 is greater than the rated air volume, which may cause the condensed water to be blown out of the water pan 5 due to the excessive wind speed, and the water in the water pan 5 can be blocked by appropriately raising the water baffle 61, so as to prevent the water from blowing, the raising height of the water baffle 61 is realized by the regular control panel lifting mechanism 62 preset in the control module, and the refrigeration is not affected due to the excessive wind speed of the fan 3 being properly blocked by the water baffle 61; h0 is the highest height that the water baffle 61 can be raised when the static pressure is 0.
In the step S4, when the current operating parameter value is less than or equal to the preset parameter value and is equal to the preset parameter value, it represents that the actual static pressure value of the external air duct of the fan 3 is equal to the rated static pressure value, and only if the rising height of the water baffle 61 is zero, the fan 3 does not blow water when working normally; when the pressure is smaller than the preset pressure, the actual static pressure value of the external air pipe pipeline of the fan 3 is larger than the rated static pressure value, the actual air volume of the fan 3 is smaller than the rated air volume, the rising height of the water baffle 61 is zero, and the fan 3 can normally work and cannot blow water.
By automatically controlling the rising height of the water baffle 61, on the basis of preventing the water blowing effect according to the actual condition, the wind resistance of the water baffle 61 is reduced as much as possible, and the influence of the water baffle 61 on the cooling and heating effects of the alternating current air duct machine indoor unit is reduced.
Further, before the step S1 of acquiring the current operating parameter value of the ac motor 4, the method includes:
s10, judging whether the air conditioner is in a heating mode or a cooling mode;
s20, when the heating mode is set, the water baffle control mode is not activated, and the rising height of the water baffle 61 is controlled to be zero;
and S30, when the air conditioner is in the cooling mode, activating and entering a water baffle control mode.
In step S10, the control module may directly obtain the operating state of the air conditioner in the air conditioning system, and determine whether the indoor unit of the ac air conditioner is in the heating mode or the cooling mode.
In the above step S20, when the heating mode is performed, no condensed water is generated, and thus it is not necessary to activate the baffle control mode, and the control of the rising height of the baffle 61 to zero is performed in order to prevent the baffle 61 from blocking the flow of the air stream.
In the above step S30, since condensed water is generated in the cooling mode, the water guard control mode needs to be activated.
Further, the step S3 of proportionally controlling the rising height of the water guard 61 according to a preset rule includes:
s31, inputting the current operating parameter value into a formula to obtain the rise height value H of the water baffle 61, where the formula is H ═ I1-I2)/(I0-I2) × H0 or H ═ H1-P2)/(P0-P2) × H0, the current operating parameter value is the current operating current I1 or the current operating power P1 of the ac motor 4, I2 is the rated operating current and is a preset value, and P2 is the rated operating power and is the preset value;
s32, generating a control signal according to H;
s33, a control signal is sent to the board lifting mechanism 62 so that the lifting height of the upper end of the water guard 61 is H.
In the above step S31, the control module determines the rising height value H of the water deflector 61 by an equation in an equal proportion, where the rising height value H is the rising height to be reached by the upper end of the water deflector 61, and is not the rising height value at this time.
In the step S32, the control module generates a control signal according to the current height H of the water guard 61, and the control signal is used to control the height at which the lifting mechanism 62 drives the water guard 61 to lift, so that the water guard 61 reaches the lifting height H.
In the above step S33, the splash guard 61 is raised and lowered on the basis of the current height so as to reach the raised height value H corresponding to the raised height value of 0 with respect to the splash guard 61.
Further, after the step S3 of proportionally controlling the rising height of the water guard 61 according to the preset rule, the method includes:
s4, judging whether a closing instruction is received;
and S5, if yes, controlling the rising height of the water baffle 61 to be zero.
In the above step S4, the close command is used to close the splash control mode.
In the above step S5, the water deflector 61 is prevented from obstructing the flow of the wind in the installation cavity 11 by controlling the rising height of the water deflector 61 to be zero.
For example, the following steps are carried out: the air volume test data of high air of a certain high static pressure air pipe machine indoor unit is as follows, and the rated static pressure is 120Pa
The factory static pressure (rated static pressure) of the unit is 120Pa, and the maximum height H0 of the water baffle 61 is 300 mm. If the actual operation current of the motor is detected to be 6.05A and is greater than the rated current 5.558A, the fact that the external air pipe of the air outlet 13 is short is shown, and at the moment, the actual air quantity of the fan 3 is larger than the designed rated air quantity, so that the condensate water can be blown out of the water receiving tray 5 due to overlarge air speed. Then, the control board gives a command to raise the water baffle 61 to a height H of (I1-I2)/(I0-I2) × H0 of (6.05-5.558)/(6.462-5.558) × 300 of 163.27 mm.

and the regression module 04 is configured to control the rising height of the water baffle 61 to be zero when the current working parameter value is less than or equal to the preset parameter value.
Referring to fig. 2, the present invention further provides an intelligent device 300, which includes a memory 400, a processor 500, and a computer program 200 stored in the memory and executable on the processor, wherein the processor 500 implements the above-mentioned water deflector control method when executing the computer program 200.
