Description

Vane control device and method of ceiling air conditioner TECHNICAL FIELD

The present invention relates to a vane control apparatus and method for a ceiling type air conditioner that measures a temperature change rate using a floor temperature sensor and implements an automatic operation setting logic for vane control according to a space recognition according to a cooling/heating obstruction determination. .

In general, air conditioners are divided into a stand type, a wall-mounted type, and a ceiling type, and cooling/heating is performed through a refrigeration cycle device by adjusting the wind direction by means of vanes.

Among them, the ceiling type air conditioner is installed on the ceiling to supply the air volume of the set temperature set by the user to the room. At this time, the vanes located on the side of the ceiling air conditioner are simultaneously opened/closed to maintain the set temperature to adjust the wind direction.

In general, the refrigeration cycle device may be composed of a circulation structure of a compressor, a condenser, an expansion mechanism, and an evaporator.

1 is a block diagram showing the configuration of a general refrigeration cycle device.

As shown in FIG. 1, the refrigeration cycle apparatus includes a compressor 10 that compresses a refrigerant to convert it into a high-temperature and high-pressure state, and converts the refrigerant in a high-temperature, high-pressure state compressed by the compressor 10 into a liquid phase, while reducing internal latent heat. A condenser 20 discharged to the outside, an expansion mechanism 30 for lowering the pressure of the refrigerant converted to liquid in the condenser 20, and the liquid refrigerant expanded in the expansion mechanism 30 is evaporated into gas. While it is configured to include an evaporator 40 that absorbs external heat.

Here, the condenser 20 and the evaporator 40 are also referred to as heat exchangers because they perform heat exchange with the outside.

Such a refrigeration cycle device is applied to a refrigerator for storing food fresh and an air conditioner for keeping the room in a comfortable state by using heat emitted from the condenser 20 and cold air formed by the evaporator 40.

2 is an exemplary view showing a device to which vane control of a conventional ceiling air conditioner is applied and an external shape.

As shown in Fig. 2, the air conditioning operation is performed by opening/closing the four vanes 21 to 24 using one stepping motor 25, the gear train 26, and the universal joint 27. .

Here, the opening/closing of the vanes 21 to 24 is operated for rapid floor heating when the indoor temperature is below a certain temperature. In addition, the vanes 21 to 24 are simultaneously opened at a preset fixed angle to guide the wind direction in the room.

In the case of the air conditioner formed on the ceiling, since it is installed on the ceiling, it has the advantage of being able to distribute and condition the air in the room relatively evenly, compared to a general type air conditioner that is installed in one room to condition air in a limited space.

However, in the case of the conventional air conditioner, the vane is simply operated depending on whether or not the set temperature has been reached each time, and the driving of the conventional vane controls a fixed vane angle in a predetermined step in order to provide a uniform airflow. Accordingly, in the conventional driving of the vane, only the same airflow is provided for the same time to all spaces according to one set temperature irrespective of different temperatures measured for each space.

This makes it difficult to provide airflow so as to minimize the temperature change for each space in an installation environment where temperature changes are different for each space or direction. That is, when airflow is provided with the same amount of air at each vane angle in a space with a different rate of temperature change, a difference occurs in the sense of airflow that a person actually feels.

In addition, if the temperature is different for each space, even if the same airflow is provided for the same period of time, there is a problem that the temperature of the entire room cannot be uniformly increased. That is, since all four vanes are operated at once, there is a problem in that the space for each vane direction is not controlled separately, so when the air conditioner is operated in an actual cafe, etc., there is a problem in that a cold place is kept cold and a hot place is maintained in a hot state.

For this reason, since it is not possible to provide a uniform heating air flow throughout the room, not only the air conditioning efficiency is lowered, but also the discomfort of the guest may be caused.

An object of the present invention is to provide a vane control apparatus and method for a ceiling type air conditioner that measures a temperature change rate using a floor temperature sensor, and implements an automatic operation setting logic for vane control according to a space recognition according to a cooling/heating obstruction determination.

The vane control device 100 of the ceiling air conditioner shown in FIGS. 3 and 4 is according to an embodiment, and its components are not limited to the embodiments shown in FIGS. 3 and 4, and some Components can be added, changed or deleted.

3 and 4, the vane control device 100 of the ceiling air conditioner according to the present invention includes a temperature sensor unit 110, a temperature change measurement unit 120, a space detection unit 130, and an operation mode setting. A unit 140, a vane control unit 150, and a vane driving unit 160 may be included. In addition, the vane control apparatus 100 of the ceiling air conditioner may further include an operation mode DB 170 that stores a vane operation setting matched according to a temperature change rate and spatial information in advance.

The temperature sensor unit 110 may measure the temperature of each of the spaces 400a, 400b, 400c, and 400d by being positioned at least two in an indoor unit 200 of the ceiling type air conditioner. In this case, the temperature sensor unit 110 may be composed of floor temperature sensors 110a, 110b, 110c, and 110d installed on the indoor floor. In addition, the temperature sensor unit 110 may be located in a direction (1) (2) (3) (4) corresponding to the vanes 201, 202, 203, and 204 of the indoor unit 200. .

The temperature change measurement unit 120 may measure a temperature change rate for each space by using the temperature change of each space measured by the temperature sensor unit 110. The temperature change measuring unit 120 may measure the rate of temperature change in a certain time unit, for example, in an hour unit.

The space sensing unit 130 may detect spatial information of a corresponding space based on a temperature change rate measured by the temperature change measuring unit 120. In this case, the sensed spatial information may store spatial information corresponding to the temperature change rate in advance, and then detect spatial information matching the sensed spatial information among the stored spatial information. In addition, the spatial information may include an open window, a blocked closed wall, a living room having a large space, and the like.

As an example, the space sensing unit 130 may detect a corresponding space having almost no temperature change rate as a closed space whose front is blocked by a wall. In addition, the space sensing unit 130 may determine that the temperature change rate is due to the solar heat introduced from the outside when the rate of change is very large over time, that is, only during the daytime, and in this case, it is detected as a space opened by a window. can do. In addition, when the temperature change rate is greater than a preset threshold and there is no change rate over time, the space detection unit 130 may detect an open space having a large space indoors, such as a living room, as there is no external influence.

The operation mode setting unit 140 sets an operation mode for vane operation and temperature control in each direction through the temperature change rate and spatial information in each direction. The set operation mode may be set using vane operation setting information matched by using vane operation setting information according to the optimization logic for each space according to the temperature change rate and spatial information in the operation mode DB 170. In this case, the driving mode setting unit 140 may further include time information and weather information in addition to temperature change rates and spatial information in each direction.

Meanwhile, the driving mode setting unit 140 may display whether or not the driving mode is set by using an LED configured in the indoor unit 200 or a remote control.

Table 1 below is an exemplary embodiment showing vane operation setting information matched according to the temperature change rate and spatial information stored in the operation mode DB 170. However, this is an exemplary embodiment and may be changed by an administrator or a user. The vane operation setting information stored in the operation mode DB 170 may be updated to be an optimal operation by continuously recognizing an operation result operated according to a temperature change rate and spatial information according to the operation mode.

The vane control unit 150 controls at least one of the first to fourth vanes 201, 202, 203, and 204 configured in the indoor unit 200 by using the operation mode set in the operation mode setting unit 140. It generates a control signal to control. In this case, the control signal may provide independent operation of the first to fourth vanes 201, 202, 203, and 204, respectively.

For example, when the first vane 201 is recognized as an enclosed space due to a high rate of temperature change, and the second vane 202 is recognized as an open space due to a low temperature change rate, the vane control unit 150 may perform the first vane 201 ) Is an operation mode matching the enclosed space, and is controlled to be set to the ON/OFF operation mode for 1 minute, and the second vane 202 is an operation mode matching the open space and can be controlled to be set to the ON operation mode at all times. have.

The vane driving unit 160 sets the first to fourth vanes 201, 202, 203, and 204 configured in the indoor unit 200 to a set operation mode based on the control signal generated by the vane control unit 150. Each operates independently.

The operation of the vane control device of the ceiling type air conditioner according to the present invention configured as described above will be described in detail with reference to the accompanying drawings. The same reference numerals as in FIG. 3 or 4 refer to the same member performing the same function.

5 is a flowchart illustrating a vane control method of a ceiling air conditioner according to an embodiment of the present invention.

Referring to FIG. 5, first, each of the indoor spaces 400a, 400b, and 400c by using at least two temperature sensor units 110 located indoors where the indoor unit 200 of the ceiling type air conditioner is installed. The temperature of (400d) is measured (S100).

At this time, the temperature sensor unit 110 may be located in a direction (1) (2) (3) (4) corresponding to the vanes 201, 202, 203, and 204 of the indoor unit 200. have.

Subsequently, the temperature change measurement unit 120 measures a temperature change rate for each space by using the temperature change of each space measured by the temperature sensor unit 110 (S200). In this case, the measured temperature change rate may be measured in a constant time unit, for example, in an hour unit.

Then, the space sensing unit 130 detects spatial information of the corresponding space based on the temperature change rate measured by the temperature change measuring unit 120 (S300). In this case, the spatial information may include an open window, a blocked closed wall, a living room having a large space, and the like.

For example, if there is little temperature change rate, that is, less than a preset first threshold, the corresponding space can be detected as a closed space whose front is blocked by a wall. In addition, if the rate of change of temperature increases over time, that is, only during the day, when the rate of change is very large (greater than the second threshold), it can be determined that it is due to the solar heat introduced from the outside. Can be detected. In addition, when the temperature change rate is greater than the first threshold value set in advance and the rate of change over time is also less than the second threshold value, there is no external influence and may be detected as a partially enclosed space having a large space indoors, such as a living room.

The operation mode setting unit 140 sets an operation mode for vane operation and temperature control in each direction through the measured temperature change rate and sensed spatial information (S400). In this case, the set operation mode may be set using vane operation setting information matched by using vane operation setting information according to the optimization logic for each space according to the temperature change rate and spatial information in the operation mode DB 170.

The vane operation setting information stored in the operation mode DB 170 may be continuously updated so as to be an optimal operation by continuously recognizing a driving result operated according to a temperature change rate and spatial information according to the operation mode. For example, it is possible to continuously recognize spatial information and update optimal operation settings by detecting the automatic entry and temperature change rate once every three months.

The first to fourth vanes 201, 202, 203, and 204 configured in the indoor unit 200 operate independently through the operation mode set in this way.

6 is a flowchart illustrating a process in which a plurality of vanes are respectively operated through an operation mode set through a vane control method of a ceiling air conditioner according to an embodiment of the present invention.

Referring to FIG. 6, after the space detection is completed (S401), when the user operates the air conditioner (S402), the measured temperature change rate is matched from the space information previously stored through the space detector 130. Space information is detected (S403). At this time, the detected spatial information is stored in advance as spatial information corresponding in advance according to the temperature change rate.

Subsequently, the temperature change rate and spatial information measured for each of the first to fourth vanes 201, 202, 203, and 204 configured in the indoor unit 200 through the operation mode setting unit 140 are stored in the operation mode DB ( 170), the operation mode is set (S404).

In this case, the operation mode may be set by using vane operation setting information matched by using vane operation setting information according to the optimization logic for each space according to the temperature change rate and spatial information in the operation mode DB 170.

In addition, at least one of the first to fourth vanes 201, 202, 203, and 204 configured in the indoor unit 200 is controlled based on the operation mode set through the vane control unit 150 (S405 ).

At this time, if at least one spatial information among the first to fourth vanes 201, 202, 203, and 204 is recognized as open (S406), the operation mode according to the preset opening through the vane driving unit 160 is changed. The vane is driven (S409).

When the contents of the automatic operation setting shown in Table 1 are described as an example, the vane driving unit 160 continuously drives the vane whose spatial information is recognized as open.

In addition, when at least one spatial information among the first to fourth vanes 201, 202, 203, and 204 is recognized as partially sealed (S407), operation according to the preset partial sealing through the vane driving unit 160 The operation of the vane is driven in the mode (S410).

When the contents of the automatic operation setting shown in Table 1 are described as an example, the vane driving unit 160 drives the operation by repeatedly swinging the vane for which spatial information is recognized as partially sealed for 2 minutes and off for 1 minute.

In addition, if at least one spatial information among the first to fourth vanes 201, 202, 203, and 204 is recognized as sealing (S408), the operation mode according to the sealing set in advance through the vane driving unit 160 is changed. The vane is driven (S411).

When the contents of the automatic operation setting shown in Table 1 are described as an example, the vane driving unit 160 drives the operation by repeatedly swinging the vane whose spatial information is recognized as sealed for 1 minute and off for 1 minute.

Through this operation, it is possible to reduce additional costs and improve the satisfaction and convenience of end customers by recognizing the space beyond simple temperature change in the space in which the ceiling air conditioner indoor unit is installed.

In addition, in the case of the existing air conditioner configuration, the vane is simply operated depending on whether or not the temperature has reached each time, but the present invention cools the user's actual use temperature request to fit the space according to the space for each vane direction through the initial temperature change. can do.

In addition, in the case of the existing air conditioner configuration, all four vanes are operated at once, so there is no separate control for the space for each vane direction. When air-conditioned, the airflow is stronger in hot places and in cold places, so that more customer satisfaction can be improved.

As described above with reference to the drawings illustrated for the present invention, the present invention is not limited by the embodiments and drawings disclosed in the present specification, and various by a person skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformations can be made. In addition, even if not explicitly described and described the effects of the configuration of the present invention while describing the embodiments of the present invention, it is natural that the predictable effects of the configuration should also be recognized.
