How to drive indoor fan motor of air conditioner
The present invention relates to an air conditioner, and more particularly, to an indoor fan motor driving method of an air conditioner that provides a more comfortable environment to the user by appropriately driving the indoor fan motor when the cooling function of the air conditioner is executed.
An air conditioner is a cooling device for the summer season that uses the principle of taking evaporative heat from ambient air when water evaporates. However, such an air conditioner has a problem in that the indoor fan motor located at the indoor unit is driven at the same time during its initial driving, and thus, an unpleasant smell and hot air are discharged together from the indoor heat exchanger which has not been cooled, thereby causing discomfort to the user.
Accordingly, the present invention has been made to solve the above problems, and when the initial operation of the air conditioner to delay the drive of the indoor fan motor for a certain period of time to sufficiently cool the indoor heat exchanger and then to remain in the indoor heat exchanger It is an object of the present invention to provide a method for driving an indoor fan motor of an air conditioner to remove odors and hot air.
That is, the present invention provides a method for driving an indoor fan motor of an air conditioner having a compressor, comprising: a first step of outputting a drive control signal to a compressor when a first set time elapses after the operation start signal is applied to the air conditioner; And a second step of outputting a drive control signal to the indoor fan motor after the second set time elapses after the compressor is driven.
1 is a schematic block diagram of an air conditioner for performing the method according to the present invention;
FIG. 2 is a flowchart illustrating a process of delaying driving of an indoor fan motor by the microcomputer of FIG. 1.
<Explanation of symbols for main parts of the drawings>
10: key input unit 20: micom
22: timer 30: compressor
40: indoor fan motor
The above objects and various advantages of the present invention will be described in detail with reference to the accompanying drawings.
1 is a schematic block diagram of an air conditioner for performing the method according to the present invention, which includes a key input unit 10, a microcomputer 20, a timer 22, a compressor 30, and an indoor fan motor ( 40).
The key input unit 10 is formed of a key matrix or a remote controller formed on its own panel of the air conditioner, and has a plurality of keys for controlling the operation of the air conditioner such as a power on / off key. Output to the microcomputer 20 by wire or wireless.
The microcomputer 20 appropriately drives the air conditioner in response to a predetermined key signal provided from the key input unit 10. That is, the microcomputer 20 drives the compressor 30 after a predetermined time, for example, 3 minutes has elapsed after the power-on signal and the cooling function key signal are applied. Such a compressor 30 driving delay time is a refrigerant based on a conventional experiment result. It is time to consider the pressure balance.
In detail, the pressure difference between the evaporation pressure and the condensation pressure generated in the air conditioner should be as small as possible to increase the pump efficiency. In other words, if the pressure difference is excessive, water leakage or the compressor 30 is overacted, thereby degrading the performance of the valve. Therefore, the normal pressure in the air conditioner should be maintained to be close to atmospheric pressure.
On the other hand, a timer 22 is mounted inside the microcomputer 20. When the timer 22 starts counting from the initial application time of the key signal and reaches the set time, the timer 22 generates a predetermined logic signal. 20 selectively controls the compressor 30, the indoor fan motor 40, and the like on / off in response to a logic signal from the timer 22.
The compressor 30 serves to compress the gas of low temperature and low pressure into gas of high temperature and high pressure, and is driven after the refrigerant pressure balancing time, for example, 3 minutes has elapsed under the control of the microcomputer 20 described above.
The indoor fan motor 40 serves to discharge cold air inside the air conditioner to the outside, and is driven after a predetermined delay time under the control of the microcomputer 20 described above.
The driving delay time of the indoor fan motor 40 is a sufficient cooling time of the indoor heat exchanger (not shown), and according to the experiment results of the applicant, a time of about 40 seconds is required. Hot air and unpleasant odors are sufficiently suppressed, so that the indoor fan motor 40 discharges the comfortable cold air to the outside.
Along with the above-described configuration, the process of delaying the driving of the indoor fan motor 40 by the microcomputer 20 according to the present invention will be described in detail with reference to the flowchart of FIG. 2.
First, the microcomputer 20 determines whether an operation start key signal is applied from the key input unit 10 (step 100).
As a result of the determination of step 100, when the operation start key signal is applied, the microcomputer 20 performs a counting operation from the time point of applying the key signal to the first set time (3 minutes) (step 102).
In step 102, when the first setting time has elapsed, the microcomputer 20 turns on the driving of the compressor 30 (step 104) and again performs a counting operation until the second setting time (40 seconds) (step 106).
In step 106, when the second set time elapses, the microcomputer 20 drives the indoor fan motor 40, thereby discharging cold air into which the unpleasant odor is suppressed (step 108).
As described above, the present invention has an effect of providing a more comfortable indoor environment to the user by driving the indoor fan motor after the indoor heat exchanger is sufficiently cooled during the initial driving of the air conditioner.
