Description

  The present invention relates to environmental control of an air conditioner, and more particularly to an air conditioner that detects the temperature from each region in a room and incorporates the result into environmental control.

Conventionally, a wide variety of air conditioners have been used in various places to obtain a more comfortable space. However, many of them are designed to control the temperature of room air.
In the early days, the technology for sensing other environmental elements was difficult, including the cost, and the influence of indoor air temperature on the user's experience was large among various controlled objects. The air temperature was the first control target.
However, environmental factors that affect the user's perceived temperature include, in addition to air temperature, relative humidity, wind speed, radiation temperature, and so on. Something that has been incorporated into control is also emerging.

  As a typical example of such a case, an indoor area is divided into a plurality of areas, each infrared sensor is provided corresponding to each divided area, and the infrared emission amount of each area collected by each infrared sensor is determined. There is one that detects the temperature of each region and controls the direction of the air flow of the air conditioner in accordance with the detected temperature to make the room temperature uniform (for example, see Patent Document 1).

  As another representative example, each infrared sensor that detects the radiation temperature of the upper space area and the lower space area of the indoor space area is provided, and the direction of the blown airflow is controlled according to the detection result of each infrared sensor. In some cases, the radiation temperature between the upper space region and the lower space region is eliminated and averaged (see, for example, Patent Document 2).

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to FIGS.
In these drawings, 1 is an indoor unit as an air conditioner body for cooling or heating a room, 1a is provided in the indoor unit 1, and a remote control signal receiving unit for receiving a signal from a remote control 2 and 1b is an indoor unit. Each infrared sensor 1c provided in the unit 1 for detecting the amount of infrared rays emitted from each area in the room is provided in the indoor unit 1 and is selected from the air direction, air temperature, or air volume of air blown from the blower. An air conditioning control device 1d for controlling at least one of them is provided in the indoor unit 1 and is a display means for displaying various types of indoor air information.

  2 is a remote controller for remotely controlling the operation of various devices of the indoor unit 1, 2a is an air-conditioning region selection switch provided in the remote controller 2, 2b is a transmitter of the remote controller, 2c is provided on the surface of the remote controller 2, A remote control display unit 2d for displaying various operation information and operation information of the unit 1 is provided on the remote control 2 and is a remote control reception unit for receiving a signal from the air conditioning control device 1c.

  FIG. 2 is a diagram showing a state in which the indoor unit 1 of the air conditioner is installed in the room. In this figure, 3 indicates a room to be air-conditioned, 4 is a window provided in the room 3, Or it is the door 4a etc., A and B have shown each area | region in the room which each infrared sensor 1b of the indoor unit 1 detects.

Next, operation | movement of the air conditioner comprised in this way is demonstrated.
First, for example, when the indoor unit 1 of the air conditioner is in a heating operation, strong cooling radiation energy from the outside air is incident from the window 4 more than incident from the wall surface of the room 3, and as a result, FIG. Although the area B closer to the window 4 of the room requires heating capacity than the area A, this phenomenon is caused by a plurality of sensors 1b provided in the indoor unit 1 from infrared energy transmitted from each area of the room 3. Can detect the necessary heating capacity of each region from the difference between the detection result and the set infrared energy.

However, at this time, as in the case of a conventional air conditioner, it is useless to air-condition not only the area A where the resident lives but also the area B where the resident does not live so as to have the same temperature. Since energy is consumed and heating is performed, in the present invention, the user can select an area to be air-conditioned.
That is, when the resident presses the air-conditioning area selection switch 2a of the microcomputer 2 in FIG. 1 and wants to air-condition the area where he / she is present, and selects the area with the air-conditioning area selection switch 2a, the remote controller of the selected area Since the signal is sent from the remote control 2 to the air conditioning control device 1c of the indoor unit 1, the air conditioning control device 1c blows the warm air of the indoor unit 1 to the area selected by the remote control 2.

  The air-conditioning area selection switch 2a of the remote controller 2 at this time is, for example, a push button type switch displaying “left”, “whole”, and “right” as shown in FIG. When the switch designated "left" of the area selection switch 2a is pushed, the area A on the left side is pushed, when the switch designated "right" is pushed, the area B on the right side is pushed, and when the switch designated "all" is pushed , Both areas A and B are heated as air conditioning target areas.

  Even if the heating operation is switched to the cooling operation and the air conditioning region selection switch 2a of the remote controller is operated, the operation is almost the same as described above, although there is a difference between heating and cooling.

As described above, according to the present invention, when the occupant designates the area to be air-conditioned by operating the air-conditioning area selection switch of the remote controller, the designated area is air-conditioned, so that it is comfortable according to the user's preference. Economical and easy-to-use air conditioners capable of efficient indoor air conditioning.
In addition, since such designation selection means is provided and the infrared ray emission amount from the designated region is controlled to be the set infrared ray emission amount, the designated region is mainly air-conditioned without air-conditioning the useless region. Therefore, an economical air conditioner that consumes unnecessary energy and makes the designated area comfortable in a speedy manner can be obtained.

  In the above description, in order to facilitate understanding of the control operation of the present invention, the air conditioning control device 1c controls the temperature of the selected region by changing only the direction of the cool air or warm air blown from the indoor unit 1. As described above, not only the change in the wind direction by the wind direction plate (not shown) but also the temperature setting button of the remote controller 2 is used to control the throttle mechanism (not shown) to change the refrigerant amount and the refrigerant temperature and thereby the wind blowing temperature. If the air flow rate is changed or the rotational speed of the blower 6 is changed to change the air volume or the like, an air conditioner that makes the selected area in a comfortable state more quickly can be obtained.

  Furthermore, in general, the human comfortable sensation temperature differs between the area where the indoor resident is in a stationary state and the area where the resident is in an active state. When the switch designated as “left” of the air-conditioning area selection switch 2a is pressed, for example, the air-conditioning is performed mainly on the left area A, so that “left” and “right” When there is a temperature difference between them and this temperature difference exceeds a predetermined temperature difference (for example, a difference of 3 ° C), the “right” air conditioning is performed. Then, control is performed using each infrared sensor 1b and the air-conditioning control device 1c so as to air-condition the area A on the left side again.

  Further, when the switch designated “right” of the selection switch 2a is pressed, air conditioning is performed mainly on the right side region B, and a temperature difference occurs between “left” and “right”. When the air temperature exceeds a specified temperature difference (for example, 3 ° C difference), air conditioning on the “left” side is performed. Control is performed by each infrared sensor 1b and the air conditioning control device 1c.

  In this way, an air conditioner that makes the room more comfortable corresponding to palatability can be obtained, and furthermore, the temperature difference between the floors in each region is reduced, so that the uncomfortable cold draft caused by the temperature difference between the floors is obtained. It is possible to obtain an air conditioner that air-conditions while suppressing the above.

  In addition, when any one of the “left”, “entire”, and “right” of the air-conditioning area selection switch 2a of the remote controller 2 is pressed, the air-conditioning air blown from the indoor unit by the air-conditioning control device 1c is changed to the pressed area. If you let it blow while swinging up and down or left and right inside, you can make a wind flow, especially when either "Left" or "Right" is pressed, "Left" and "Right" Since the temperature difference between the regions is reduced by the flow of the swung wind, an air conditioner that eliminates an unpleasant cold draft and makes the selected region comfortable can be obtained.

  In addition to the above, there are the following methods for maintaining a comfortable space by reducing the temperature difference between the “left” and “right” regions.

  First, either the “left” or “right” switch of the air-conditioning area selection switch 2a is pressed, and the area selected by this switch is air-conditioned by the wind blown from the indoor unit 1, and this air-conditioning selects the selected area. When there is a difference between a temperature difference range set in advance (for example, 1 ° C. to 2 ° C.), that is, 3 ° C. or more, between the indoor unit 1 and the other non-selected areas, The direction of the blown air is blown into the selected area on the non-selected area side so that the temperature difference between the selected area and the other non-selected areas is reduced, thereby creating a comfortable space while suppressing energy consumption.

Further, when the temperature difference between the region selected by the switch 2a and the other non-selected region is within a preset temperature difference range, for example, within 2 ° C., the air conditioning control device maintains the small value. 1c controls the direction of the wind blown out from the indoor unit 1.
That is, when the direction of the wind blown out from the indoor unit 1 is in the center of the selected area, when the difference is within 2 ° C., the direction is maintained, and the above-mentioned direction is also in the state from 3 ° C. to 2 ° C. When the temperature reaches ℃, the state is maintained.
However, when the temperature difference between the region selected by the switch 2a and the other non-selected region is equal to or less than the preset temperature difference range, the selected region opposite to the non-selected region is air-conditioned. The air conditioning control device 1c changes the direction of the wind blown out from the indoor unit 1.

As described above, an air conditioner that creates a comfortable space while suppressing energy consumption and draft of airflow can be obtained.
Moreover, in the above description, the air-conditioning control apparatus 1c shows about two examples as an implementation representative example which air-conditions each area | region according to the difference of the infrared radiation amount of the area | region which the remote control 2 selected, and the area | region other than that. However, even if it is not necessarily this way, any configuration that creates a comfortable space by air-conditioning the selected area and other areas while suppressing energy consumption and airflow draft May be good.

Embodiment 2. FIG.
In the second embodiment, as shown in FIG. 4, the remote controller 2 of the first embodiment is provided with an installation position setting means 2f for setting in which part of the room 3 the indoor unit 1 is installed, and this installation position. A wind direction varying means (not shown) for varying the wind direction width for each region of the room 3 according to the setting means 2f is provided in the air conditioning control device 1c of the indoor unit 1, and the indoor unit 1 is installed in the room as shown in FIGS. The wind direction width of the wind blown out from the indoor unit 1 is adjusted to prevent the wind from being extremely directed toward the wall surface.
Note that reference numeral 2e in this figure denotes a setting position display unit that displays the setting position of the installation position setting means 2f, and the other configuration is almost the same as that of the first embodiment, so that the description thereof is omitted.

Next, the operation thus configured will be described.
First, when the indoor unit 1 is not installed at the center but is installed and operated at the corner of the room as shown in FIGS. 5 and 6, the air direction variable width of the indoor unit 1 is originally at an angle in the direction of 180 degrees to the left and right. For example, even if an indoor resident operates the air-conditioning area selection switch 2a of the remote control 2 and instructs to air-condition mainly in the left direction where he is, It will be blown out in the direction.

Therefore, in the present invention, when the installation position setting means 2f of the remote controller 2 is operated to indicate that the indoor unit 1 is installed on the left side, that is, when the installation position setting means 2f is set to the left, Since the set installation signal is transmitted from the remote controller 2 to the air-conditioning control device 1c, the air-conditioning control device 1c that has received this signal changes the air direction width blown from the indoor unit 1 from 180 degrees as shown in FIG. It is limited within α and blows out within the angle α.
Also, when the indoor unit 1 is installed on the right side, as shown in FIG. 6, the same operation is performed to blow out, so even if the indoor unit 1 is installed in the left and right corners of the room, useless directions Therefore, an air conditioner that efficiently air-conditions the room can be obtained.

  At this time, as shown in FIG. 7, when each infrared sensor 1b detects each region, each infrared sensor 1b wraps (superimposes) each other region to detect the amount of infrared rays. When the mounting angle of the infrared sensor 1b is adjusted, the air conditioner body is installed at the right or left corner of the room, and either right or left is selected as the area to be air-conditioned by the selection switch 2a of the remote controller 2 in conjunction with the installation state. However, as shown in FIGS. 8 (a) and 8 (b), the selected region is further away from the corner side wall surface, and the air-conditioning region is widened accordingly. As a result, the air conditioner is divided into almost equal areas while air is blown in a wasteful direction, so that the room is more efficiently divided even if the indoor unit is installed at the left and right corners of the room. Air conditioner that air-conditions well Obtained.

  In addition, when each infrared sensor 1b wraps (superimposes) and detects each other region, if the wrapping is ½ or more, the amount of infrared radiation detected from each region approximates, so the wrap region is 1 / 2 or less is desirable.

Further, when the indoor unit 1 is installed in the corner of the room in this way, one of the infrared sensors 1b detects the amount of infrared rays emitted from the floor, but the other sensor 1b has a wall that is far from the floor temperature. The amount of infrared rays emitted from the air is detected, and the air conditioning control device air-conditions each area in the room based on the detection result. In this case, as shown in FIGS. 9 and 10, the direction of each infrared sensor 1 b is changed by the detection variable means 1 h according to the installation position of the indoor unit 1, and the indoor regions are equally divided by the detection variable means. , So as to detect the amount of infrared radiation emitted from each of the variably divided areas, that is, each infrared sensor 1b divides the room into almost equal areas, and detects the amount of infrared radiation emitted from each of the equally divided areas. When so as to control Te, or excessively conditioned space, since no longer conditioned by consuming unnecessary energy, economical air conditioner is obtained.
In addition, if the detection variable means 1h changes the direction of each infrared sensor 1b to detect it, it is not necessary to wrap each area detected by each infrared sensor 1b and detect infrared rays in each area. It is possible to obtain an air conditioner that accurately air-conditions without being influenced by.

  In the first and second embodiments described above, the amount of infrared rays in each region is detected using a plurality of infrared sensors 1b, but when a multi-element infrared sensor is used as the infrared sensor, it is shown in FIG. As described above, the indoor area is divided into, for example, Xa, Xb, and Xc using this single multi-element infrared ray, and the amount of infrared rays in each divided area can be detected. A machine is obtained.

Embodiment 3 FIG.
In the third embodiment, as shown in FIG. 12, a main body display means 1c is provided in the indoor unit 1 of the first and second embodiments.
In this figure, 1f is an air conditioning target area display unit that is provided in the air conditioner main body and displays the current air conditioning target area. This air conditioning target area display unit 1f displays the area selected by the air conditioning area selection switch 2c of the remote controller. To do. Reference numeral 1g denotes an environmental element data display unit that displays each environmental element status recognized by the air conditioning control device 1c.
Since other configurations are substantially the same as those in the first and second embodiments, description thereof is omitted.

Next, this operation will be described.
When an indoor resident operates the air conditioning area selection switch 2c of the remote controller 2 and presses one of the “left”, “right”, or “whole” push buttons, the signal from the remote controller 2 causes the air conditioning control device 1c to be activated. Therefore, the air-conditioning target area display unit 1f as a display means displays “left”, “right”, or “whole” based on the transmission result.

When the “all” button is pressed, as shown in FIG. 12, the air-conditioning target area display section 1f has no display section for displaying “entire”, so that both “left” and “right” are displayed. Display “whole” by lighting up the display.
In this way, the display space for the display content can be reduced, and the number of parts is reduced, so that an economical and compact display unit can be obtained.

The environmental element data display unit 1g displays each environmental element status recognized by the air conditioning control device 1c, and displays it in conjunction with the air conditioning target area display unit 1f described above.
That is, for example, if the left area in the room is the air conditioning target area, the “left” display of the air conditioning target area display unit 1f is turned on, and the environmental element data display unit 1g below it is incident from that area. The floor and wind temperature based on the amount of energy is displayed.
If the display is interlocked in this way, the display space for the display contents can be further reduced, and the number of parts is reduced, so that an economical and compact display unit can be obtained.

  Furthermore, when the display content of the environmental element data display unit 1g and the display content of the display unit 2c of the remote controller 2 are linked, an air conditioner that makes it easy for the user to recognize the relationship between the operation of the indoor unit and the remote control operation. can get.
