Description

[0001] The present invention relates to a method of controlling an air conditioner,

The present invention relates to a control method of an air conditioner.

The air conditioner is an appliance for keeping the indoor air in the most suitable condition according to the purpose and purpose. For example, in the summer, the room is kept cool and the winter is warmed. In addition, the humidity of the room is controlled and the air in the room is controlled in a pleasant and clean state. The air conditioner is driven by a refrigeration cycle, and may include a compressor, a condenser, an expansion device, and an evaporator.

Such an air conditioner is provided with a suction portion for sucking air in the indoor space, a heat exchanger for heat-exchanging with the air sucked through the suction portion, and a discharge portion for discharging the air heat-exchanged in the heat exchanger to the indoor space. The air conditioner may be provided with a blowing fan for generating an air flow from the suction unit to the discharge unit.

In addition, the air conditioner may include various devices such as a cleanliness sensor for detecting the cleanliness of indoor air, a dust collector or filter for cleaning the air, and a sensor for sensing the surrounding environment.

In addition, the air conditioner may have various functions for the convenience of the user. Particularly, a function of automatically controlling the set temperature without a preset temperature inputted by the user can be provided.

The prior literature related to this is as follows.

(1) First Prior Art: Registration No. 1238661: Automatic adjustment method of set temperature of air conditioner.

(2) Second Preceding Document: Japanese Patent Application Laid-Open No. 1999-0069152, a method for automatically setting an initial desired temperature of an air conditioner.

The above-mentioned prior art documents sets the temperature automatically based on the stored memory, or simply compares the previous desired temperature with the current desired temperature. According to such prior art documents, since only the simple stored memory and the immediately preceding temperature value are simply compared, there is a problem that the set temperature can not be controlled to a proper temperature for the user.

In addition, when a sudden change in conditions such as a seasonal change or a user change occurs, it can not be detected, which may cause inconvenience to the user.

The present invention provides a control method of an air conditioner that can be automatically controlled to a set temperature suitable for a user.

The present invention also provides a control method for an air conditioner that detects a sudden change in condition and automatically changes the set temperature in accordance with the change.

In the control method of an air conditioner according to the present invention, the air conditioner is turned on and the cumulative temperature corresponding to the average value of the set temperature set after the use of the air conditioner is checked. And determining a difference between the cumulative temperature and the latest temperature, and if the difference between the cumulative temperature and the latest temperature is equal to or less than a predetermined temperature value (B) When the difference between the cumulative temperature and the latest temperature is greater than a predetermined temperature value (B), the air conditioner is operated with the latest temperature as a set temperature.

The predetermined temperature value B may be determined as a temperature value indicating a sudden change in external conditions such as a seasonal change and a user change.

The predetermined temperature value (B) may be set to 3 degrees.

The air conditioner is turned on, and the room temperature and the outdoor temperature are compared. When the difference between the room temperature and the outdoor temperature is less than the predetermined temperature value (A), the accumulated temperature and the recent temperature can be confirmed.

Wherein when the difference between the room temperature and the outdoor temperature is equal to or higher than a predetermined temperature value (A), the air conditioner operates with a value obtained by subtracting the predetermined temperature value (A) from the outdoor temperature, And in the case of heating operation, the air conditioner can be operated by setting the value obtained by adding the predetermined temperature value (A) at the outdoor temperature to the set temperature.

The predetermined temperature value A may correspond to a temperature value considering a user's discomfort due to a sudden temperature difference and a load of the air conditioner.

The predetermined temperature value (A) may be set to 7 degrees.

When the air conditioner is turned ON and the user inputs a predetermined set temperature, the air conditioner can be operated by the inputted set temperature.

The set temperature for determining the cumulative temperature and the latest temperature may include a set temperature input by the user and a set temperature automatically set.

The latest temperature may be set to an average value of 10 preset temperatures at which the air conditioner was recently operated.

According to the present invention, it is possible to automatically improve the user's convenience by determining the set temperature automatically.

In addition, a sudden change of the external environment is sensed to determine the set temperature, and the air suitable for the user can be provided.

This can compare the average value of the set temperature set during the entire operation of the air conditioner with the average value of the set temperature set in the latest operation and detect a sudden change of the external environment when the temperature is equal to or higher than the predetermined temperature value.

In particular, there is an advantage that a seasonal change or a user change can be easily detected.

Further, the set temperature may be input by the user, and the set temperature may be automatically determined.

In addition, it is possible to control the user's health and the air conditioner effectively by determining the set temperature by adjusting the difference between the outdoor temperature and the room temperature so as not to be too large.

FIG. 2 is a view showing a configuration of the air conditioner with a partial configuration omitted.

As shown in FIG. 1, the air conditioner is provided with an indoor unit 1 disposed in a predetermined indoor space. In detail, the indoor unit (1) is disposed in the indoor space so that the air conditioner provides conditioned air to the indoor space.

Referring to FIGS. 1 and 2, the indoor unit 1 includes a discharge unit 10 for discharging the heat-exchanged air from the outside and a blowing unit 20 for sucking and blowing air.

The discharge part (10) and the blowing part (20) are vertically arranged in the indoor unit (1). Further, the indoor unit 1 is provided with discharge ports 13 and 14 to be described later, and a suction port (not shown) may be provided at the rear lower portion thereof.

2, the discharging unit 10 is provided with discharging units 11 and 12 for discharging the air introduced from the discharging unit 20. As shown in FIG. The discharging unit includes a first discharging unit (11) and a second discharging unit (12). The first discharge unit (11) and the second discharge unit (12) are cylindrically shaped and can be rotated about a rotation center axis parallel to each other.

The first discharge unit (11) and the second discharge unit (12) can independently rotate and adjust the discharge direction of air. That is, the first discharging unit 11 and the second discharging unit 12 can discharge air in different directions.

The upper part of the first discharging unit 11 and the second discharging unit 12 may be shielded and the lower part may be opened. Accordingly, the air blown from the blowing unit 20 can be introduced into the lower portion of the first discharge unit 11 and the second discharge unit 12.

The first discharge unit (11) and the second discharge unit (12) may be provided with discharge ports (13, 14) for discharging air to the outside, respectively. That is, the air introduced from the airflow-supplying portion 20 can be discharged to the outside through the respective discharge ports 13, Specifically, the ejection opening includes a first ejection opening 13 provided in the first ejection unit 11 and a second ejection opening 14 provided in the second ejection unit 12.

The discharging unit 10 may further include a center body 15 provided between the first discharging unit 11 and the second discharging unit 12. The center body 15 can be understood as a structure for shielding a gap between the first discharge unit 11 and the second discharge unit 12. [

In addition, the center body 15 may include a display unit (not shown) for indicating an operation state of the air conditioner, and an input unit (not shown) for inputting an angular motion command of the air conditioner.

The air-blowing section 20 is provided with a blowing fan 22 (FIG. 3) for forced convection of air. The blowing fan 22 can be operated in different air volumes as required. For example, the blowing fan 22 may be divided into five stages, namely, the first to fifth stages, and the air flow rate of the blowing fan 22 increases from the first stage to the fifth stage.

That is, the first step may be understood as a 'minimum air volume', and the fifth step may be understood as a 'maximum air volume'. When the air blowing fan 22 is operated in the first step, the air flow is weakest and consumes the least amount of power. When the air blowing fan 22 is operated in the fifth step, the air flow is strongest and consumes the most power.

The number of such steps is exemplary, and the blowing fan 22 can be operated at various air volumes having a predetermined air volume range determined by the minimum air volume and the maximum air volume.

The blowing fan 22 includes a first blowing fan and a second blowing fan that are operated independently of each other. That is, if necessary, at least one of the first blowing fan and the second blowing fan can be operated.

The blowing unit 20 includes a first fan housing 21 and a second fan housing 23 in which the first blowing fan and the second blowing fan are respectively received. The first fan housing 21 is provided with a first duct portion 25 communicating with the first discharging unit 11 and the second fan housing 23 is provided with a second duct portion 25 communicating with the second discharging unit 12 The second duct portion 27 is provided.

The air blown by the first blowing fan housed in the first fan housing 21 moves to the first discharging unit 11 through the first duct portion 25 and flows into the first discharging port 13 To the outside. The air blown by the second blowing fan housed in the second fan housing 23 moves to the second discharging unit 12 through the second duct portion 27 and flows into the second discharging opening 14, As shown in FIG.

Further, an indoor heat exchanger (not shown) for exchanging heat with the refrigerant may be provided between the air flow-in portion 20 and the air inlet. When the airflow 20 is operated, air can be introduced into the casing 3 through the air inlet, cooled by the indoor heat exchanger, and discharged to the outside through the discharge unit 10.

In addition, the air conditioner according to the present invention is provided with an outdoor unit (not shown) arranged in a predetermined outdoor space. The outdoor unit is provided with an outdoor heat exchanger and a compressor (38, FIG. 3) for forming a predetermined refrigerant cycle together with the indoor heat exchanger.

The compressor (38) compresses and discharges gaseous refrigerant to high temperature and high pressure. Particularly, according to the operation of the compressor 38, refrigerant circulates through the refrigerant cycle and can be heat-exchanged in the indoor heat exchanger and the outdoor heat exchanger.

3 is a view showing a control configuration of an air conditioner according to an embodiment of the present invention.

As shown in FIG. 3, the air conditioner according to the present invention is provided with a control unit 40 for controlling the respective components of the above-described air conditioner. 3, only a part of the configuration related to the control unit 40 is shown for convenience of explanation.

The control unit 40 may operate the blowing fan 22 in any one of the first to fifth steps. In addition, the controller 40 may operate the compressor 38 to circulate the refrigerant.

In addition, the air conditioner may include a power supply unit 30 for transmitting an ON / OFF signal of the air conditioner to the control unit in response to a command from the user. The power supply unit 30 may be provided as a device such as a remote controller or an app of a mobile terminal carried by the user.

In addition, the user can determine the set temperature together with the ON of the air conditioner through the power supply unit 30. Accordingly, the control unit 40 can receive the ON signal of the air conditioner and the set temperature or the OFF signal of the air conditioner from the power supply unit 30. [

In addition, the air conditioner is provided with an indoor temperature sensor 32 for measuring the temperature of the indoor space. The room temperature sensor 32 may be disposed at any one of the indoor spaces, and may be disposed at the suction port side of the indoor unit 1 in general.

In addition, the air conditioner is provided with an outdoor temperature sensor 33 for measuring the temperature of the outdoor space. The outdoor temperature sensor 33 may be disposed at any one of the outdoor unit and the outdoor unit. Alternatively, the outdoor temperature sensor 33 may correspond to a configuration that receives temperature information from a weather station or the like.

In addition, the air conditioner is provided with a memory unit 36 for storing predetermined information. The memory unit 36 may transmit information to the controller 40. [ In addition, the memory unit 36 may store information transmitted from the controller 40.

Hereinafter, the control of the air conditioner according to the present invention will be described in detail with the control arrangement as described above.

FIG. 4 is a view illustrating a control flow of the air conditioner according to an embodiment of the present invention.

As shown in FIG. 4, the air conditioner is turned on according to an input of the power supply unit 30 (S10). At this time, the user can set the set temperature together with the input of the power supply unit 30 as described above. Further, the user can be operated in the automatic setting mode in which the predetermined set temperature is not set.

Hereinafter, a method of automatically setting the set temperature in the air conditioner operated in the automatic setting mode will be described in detail.

First, the room temperature measured by the room temperature sensor 32 and the outdoor temperature measured by the outdoor temperature sensor 33 are compared. Specifically, it is determined whether a difference between the room temperature and the outdoor temperature is less than a predetermined temperature value (A) (S20).

For example, the predetermined temperature value A may be set to 7 degrees. Such a temperature value is an arbitrary value so that the air conditioner is not operated so that the room temperature and the outdoor temperature have too much difference. This is set for the user's health and efficient operation of the air conditioner.

If the difference between the room temperature and the outdoor temperature is equal to or higher than the predetermined temperature value (A), the set temperature is determined by subtracting the predetermined temperature value (A) from the room temperature (S30).

For example, if the outdoor temperature is 35 degrees in hot summer, and the room temperature is 27 degrees, the difference is 8 degrees. Since this is larger than the predetermined temperature value A set at 7 degrees, the set temperature is determined to be 28 degrees minus 7 degrees at the outdoor temperature.

Also, when the outdoor temperature is 18 degrees in cold winter, and the room temperature is 27 degrees, the difference is 9 degrees. Since this is larger than the predetermined temperature value B set at 7 degrees, the set temperature is determined at 25 degrees plus 7 degrees at the outdoor temperature.

That is, in the cooling operation, the air conditioner is operated by setting the value obtained by subtracting the predetermined temperature value (A) from the outdoor temperature as the set temperature, and in the case of the heating operation, the predetermined temperature value A ) Is set as the set temperature, and the air conditioner is operated.

If the difference between the room temperature and the outdoor temperature is less than the predetermined temperature value A, the accumulated temperature and the latest temperature stored in the memory unit 36 are checked (S40 and S50). For convenience, it is described in FIG. 4 that the accumulated temperature is confirmed (S40) and the latest temperature is confirmed (S50), but this can be performed regardless of the order.

At this time, the cumulative temperature means an average value of all set temperatures that have been set since the start of the operation of the air conditioner. The set temperature includes all set temperatures set by the user or automatically set.

Also, the latest temperature refers to an average value of N set temperatures at which the air conditioner was recently operated. For example, when the air conditioner is operated N times or less, the cumulative temperature and the latest temperature are the same. The N times may be set to 10 at an arbitrary value.

Then, the cumulative temperature is compared with the latest temperature. Specifically, it is determined whether the difference between the cumulative temperature and the latest temperature is less than a predetermined temperature value (S60).

For example, the predetermined temperature value B may be set to 3 degrees. The temperature value is an arbitrary value and means a temperature value at which the accumulated temperature and the recent temperature are judged to have a somewhat large difference. That is, the predetermined temperature value (B) can be understood as an index indicating a sudden change in external conditions such as a seasonal change, a user change, and the like.

If the difference between the room temperature and the outdoor temperature is less than or equal to the predetermined temperature value (B), the set temperature is determined as the accumulated temperature (S70). It can be understood that no change has occurred recently.

On the other hand, if the difference between the room temperature and the outdoor temperature is larger than the predetermined temperature value B, the set temperature is determined as the latest temperature (S80). In this case, it can be understood that a sudden change in external factors has occurred.

For example, if the cumulative temperature is 25 degrees and the recent temperature is 29 degrees, the difference corresponds to 4 degrees. Since this is larger than the predetermined temperature value B set at 3 degrees, the set temperature is determined to be the latest temperature 29 degrees. At this time, it can be understood that a change has occurred in whether the season has changed from the summer season to the autumn season, or has changed to a user who feels a lot of cold.

The set temperature is automatically set through the above process, and the air conditioner can be operated such that the room temperature reaches the set temperature.
