The present invention relates to an operation control apparatus and method for an air conditioner, and more particularly, to an operation control apparatus and method for an air conditioner for determining a current time using a photoconductive element and determining an operation pattern for each time zone. .

In general, air conditioning refers to maintaining air, temperature, humidity, airflow, and cleanness of air in a certain room or building at optimum conditions according to the purpose of use of the room, and the like. to be.

Conventional air conditioners are equipped with functions such as cooling, heating and dehumidification, and humidification to perform air conditioning, and in recent years, various functions varying driving patterns to provide a more comfortable environment and convenience to users, for example, sleeping. It has additional functions such as driving, turbo driving and mild driving.

When the user wants to maintain the indoor space comfortably using such a conventional air conditioner, air conditioning may be performed by selecting an operation pattern suitable for the environmental conditions at that time. For example, in the hot afternoon of the summer, the effect of rapid cooling can be obtained by selecting turbo operation, which is a powerful cooling operation. At this time, the air conditioner exhibits the cooling capacity over the original rated capacity to provide the air conditioning environment desired by the user within a short time. In addition, when the user selects the sleep operation at bedtime, the room temperature is automatically adjusted according to the preset control pattern.

Conventional air conditioners that perform the functions as described above can be operated by the user's direct selection, despite providing various functions in addition to the original heating and cooling functions, so children and the elderly have insufficient understanding of each driving pattern. Therefore, the efficient use of the air conditioner is not possible and there is a problem that the general user also has to specify the operation pattern individually according to each environment.

Accordingly, an object of the present invention is to automatically recognize the point of use in order to solve the problems of the conventional air conditioner as described above to provide an air conditioner for differently controlling the operation pattern without a separate key input according to the air conditioning environment characteristics of each point Its purpose is to.

In order to achieve the above object, the present invention is provided with a variable capacity compressor and a blowing fan, and in the air conditioner for controlling the operation of the compressor and the blowing fan according to the difference between the room temperature and the set temperature, the light to sense the brightness of the outdoor The controller may further include a controller configured to determine a time band corresponding to a current time according to a detection result of the light detector, and determine a driving pattern corresponding to each time band. In addition, the operation control method according to the present invention is a variable variable air conditioner having a variable speed drive, the process of setting a reference time, the current time is determined by the time elapsed from the reference time and the time band including the current time The process of determining, characterized in that it comprises a process of controlling the operation of the air conditioner by varying the characteristics of the operation pattern according to each time band including the current time.

Hereinafter, the configuration and the effect according to the preferred embodiment of the present invention will be described in detail.

1 is a block diagram showing a schematic configuration of an air conditioner according to the present invention. As shown in FIG. 1, the air conditioner according to the present invention has a power supply voltage unit 20 for supplying power from each device when the operation is started, an indoor temperature detection unit 70 for detecting an indoor temperature, and a user The light sensing unit 40 includes an indoor temperature setting unit 30 for setting a desired indoor temperature, an indoor humidity detecting unit 90 for detecting indoor humidity, and a photoconductive cell (CdS) having different characteristics depending on the amount of light. ) And an operating frequency of the compressor based on a difference between the sensing temperature of the indoor temperature detecting unit 70 and the set temperature of the indoor temperature setting unit 30, and according to the detection result of the light detecting unit 40. The controller 10 determines a driving pattern according to a viewpoint, a compressor driver 60 driving the compressor by receiving the driving frequency determined by the controller 10, and a wind direction of the discharge air stream under the control of the controller 10. Blowing fan control unit 50 to adjust, and each of the air conditioner It is composed of a function selection unit 80 receives the operation from the user.

The light sensing unit 40 can be installed well in the outdoor unit of the air conditioner and has a photoconductive cell CdS connected to a power source, one end of which is connected in series with the photoconductive cell CdS, and the other end of the photoresist R is grounded. It is composed of The middle tap of the photoconductive cell CdS and the resistor R is connected to an input terminal of the controller 10.

2 shows a change in the resistance value of the photoconductive cell CdS by light in 24 bands per day. The photoconductive cell CdS has a characteristic that the resistance value decreases when the amount of light is large, that is, when the outdoor is bright, and when the outdoor level is dark, that is, the resistance value increases when the light is low. As shown in FIG. 2, the resistance value of the photoconductive cell CdS changes with each time on the basis of the day when the sunrise time is 06 o'clock and the sunset time is 18 o'clock.

The air conditioner according to the present invention detects the resistance value of the photoconductive cell CdS and calculates a reference time required to recognize the current time. Using the calculated reference time as an initial state, the current time is counted to determine an operation pattern suitable for each point of use. The driving pattern determined in the above manner and the usage environment in which each function is performed are as follows.

In general, in the time zone (B band A) from 06 am to 12 am, the outdoor temperature and the indoor temperature are relatively low, but the humidity is high, causing unpleasant dehumidification. In the dehumidification operation, the dehumidification operation and the dehumidification operation are automatically performed according to the difference between the set temperature and the room temperature.In the dehumidification operation, the compressor is repeatedly operated and stopped in the dehumidification operation to remove moisture. During heating, room temperature is adjusted while repeating heating and cooling. At this time, the indoor blower fan is operated with the super breeze or the air volume stored in the controller regardless of the air volume control switch. The cold dehumidification operation is performed when the set temperature is lower than the room temperature, and the difficult dehumidification operation is performed when the set temperature is higher than the room temperature.

In the time zone (B band) from 12 am to 18 pm, the indoor and outdoor temperatures are high and the user's activity is increased so that a lot of heat is felt. Therefore, a turbo cooling function is required to perform a powerful cooling function. The main feature of the turbo cooling is to increase the number of revolutions of the indoor blower fan and the compressor to the maximum to achieve a cooling capacity of more than the rated capacity in a short time. In addition, the evening time, which is the time zone (C band) from 18 pm to 22 pm, is a time zone with low temperature and low user activity, thus reducing the operating frequency of the blower fan and the compressor, thereby reducing the noise and quiet operation. need.

Since the time zone (D band) from 22 pm to 06 am is generally a bedtime, the bedtime operation is appropriately controlled at room temperature in consideration of the decrease in body temperature control function at bedtime. Sleeping operation is a function of cooling and dehumidifying in summer and reducing the indoor temperature to the set temperature and increasing it by a predetermined temperature according to the time elapsed, or heating it in winter and raising the indoor temperature to the set temperature. Operate by lowering the temperature to maintain a comfortable environment during bedtime.

3 is a flowchart of the main routine of the operation control method of the air conditioner according to the present invention.

If it is not determined by determining whether the reference time is set in step 100, the reference time is set through the reference time setting subroutine, and if the reference time is already set, the time timer is increased in step 110 to the present time. Count. If it is determined that the operation of the air conditioner is turned on in step 120, the compressor is stopped in step 200, and the blower fan is stopped in step 210.

In operation 130, when operation is turned on, it is determined in which band the current time is included as a value counted from the reference time to the current time in step 130. If the current time is included in the band A representing the band from 06 am to 12 am, step 140 recognizes that it is the morning time and performs only the dehumidification function to drive the compressor to achieve air conditioning by removing moisture in the air.

As a result of the determination of step 130, if the current time is not included in the A band, it is determined whether the current time is included in the B band. As a result of the determination of step 150, if the current time is included in the band B representing the time from 12 am to 18 pm, step 160 recognizes that the user's activity is increased and the indoor temperature is high in the afternoon, and thus provides powerful cooling. Rapid cooling is performed by performing turbo cooling.

If it is determined in step 150 that the current time is not included in the B band, it is determined whether the current time is included in the C band indicating a time from 18 pm to 22 pm in step 170 and the current time is included in the C band. In 180, since the amount of activity is small and indoor and outdoor are quiet, the operation frequency of the compressor is lowered to perform the quiet function so as to provide comfortable air conditioning according to a preset control pattern.

If it is determined in step 170 that the current time is not included in the C band, it is determined that it is included in the D band representing the time from 22 pm to 06 am, and in step 190, the sleeping operation is performed.

4 is a flowchart of a subroutine for setting a reference time in the operation control method of a known conditioner according to the present invention. The reference time setting method for grasping the progress of the present time applied in the present invention, as shown in the flowchart shown in FIG. 4, first determines whether a sunset time, which is a time changing from day to night, is set in step 310. If the sunset time is not set as a result of the determination in step 310, it is determined whether the previous step is day by the detection result of the light detecting unit 40 in step 410, and it is determined whether the current step is night in step 420. Determine the sunset time, which is the time from day to night. As a result of the determination of the step 420, the sunset time is cleared in step 430, and the sunset time is set in step 440.

If the sunset time is set in step 440, the timer is increased in step 320 to check the time elapsed. In step 330, it is determined whether the previous step is night based on the detection result of the light detecting unit 40, and if the previous step is not night, step 310 is performed. As a result of the determination of the step 330, if the previous step is night, in step 340, it is determined whether the current step is day. If the step is low, that is, if the sunrise time has arrived, step 350 is performed.

As a result of the determination of the step 340, when the sunrise time is reached, in step 350, the reference time is calculated by dividing the value of the timer so far increased by 2 and adding 0:30 to the value, and calculating the calculated time in step 360. Set to reference time.

Generally, midnight (0 o'clock) has the same sunset time and sunrise time, but in Korea, where the hardness is about 7 degrees different from Japan, the median value of sunset time and sunrise time is 0:30. This feature is consistent with changing seasons and changing sunrise and sunset times. Therefore, at any time of the year, a reference time for determining the current time may be set by detecting a change in the resistance value of the photoconductive cell CdS.

As described above, by recognizing the current time by the air conditioner according to the present invention and controlling the operation pattern automatically according to the air-conditioning environment at each time point, the user does not have to set the driving pattern directly, which is more convenient. There is an effect of improving the air conditioning efficiency by maintaining the optimum air conditioning conditions at all times.
