DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art An example relatively close to the present invention relates to the operation control of a refrigeration system for a refrigeration container.
No. 3 discloses this. However, this is intended to improve the operability by using a main body operating device installed near the refrigeration apparatus main body and a remote operating device installed in the cabin or the like, and does not solve the problems inherent to the air conditioner.

[0003]

In the case of an air conditioner, an operating device is usually installed in a room to be temperature-controlled. For this reason, it is necessary for the user to enter a room where the air conditioner is not operating and perform the first operation. At this time, the user must temporarily accept an unpleasant environment in which the set conditions have not been reached.

[0004] In addition, although it is customary to automate the stop operation of the air conditioner by using a timer, in the case of a timer, the stop time must be determined in advance, which is inconvenient when the exit time is not known. If the timer is not used, the user may forget the stop operation when leaving the room and consume wasteful power.

An object of the present invention is to provide a method of operating an air conditioner that overcomes discomfort, and at the same time, to save power.

[0006]

The present invention achieves the above object.
The user outside the room where the air conditioner is located.
Receives signals transmitted by radio from the transmitting device
And the transmitter approaches a certain distance and continues to approach
Activate the air conditioner when it detects
You.

[0007]

With the above arrangement, the air conditioner can be automatically operated before or immediately after the user enters the room. Further, the air conditioner can be automatically stopped when leaving the room.

[0008]

FIG. 1 is a flow chart showing the structure of an air conditioner operating method according to the present invention. As shown in this figure, the movement of the user is detected by the entry detection 1 and it is determined whether or not to enter the room by the entry determination 2. Then, when it is determined to enter the room, the air conditioner is operated.

FIG. 2 is an explanatory diagram showing an embodiment of the present invention. The air conditioner 11 of this embodiment has an entrance sensor 13 such as an optical sensor and a microphone connected to the vicinity of the entrance of the room via a communication line 12, and has an exit detector 16 in the room. In this embodiment, the approach of the user is detected by the entry detection means 13, and it is determined whether or not to enter the room by the entry discrimination means 2 added to the entry detection means 13. A signal is sent to the air conditioner 11 to operate the air conditioner 11. Alternatively, the room entry discrimination means 2 is added to the air conditioner 11 and sends a signal from the room entry detection means 13 to the room entry discrimination means 2 via the communication line 12 to activate the air conditioner 11 when it is determined that the room is to be entered. You can also.

[0010] A method for judging the entry includes entry detection means 1.
There is a method of utilizing the reflection of infrared rays emitted from the third method, a method of detecting an increase in the volume of footsteps with a microphone, and the like.

In this embodiment, the presence / absence of a room user is detected by the exit detection means 16 installed in the main body of the air conditioner. However, the entrance detection means 13 installed near the entrance of the room is provided. Can be used as a room exit detecting means. In other words, a method using infrared reflection,
For example, a method of detecting a decrease in the volume of footsteps with a microphone. In this embodiment, the exit detection means 16 is installed in the air conditioner main body, but may be installed in another place in the room, for example, near the door 14.

FIG. 3 is an explanatory view showing a second embodiment of the present invention. In this embodiment, the door 14 or the door knob 2
A room entry detecting means 1 is installed in the room 1, the room is determined immediately before entering the room, and the air conditioner 11 is operated.

In this case, the criteria for judging entry are to insert a key into the keyhole of the door 14, open the key of the door 14, contact the door knob 21 outside,
, Or the door 14 opens.

Conversely, criteria for judging exit using this configuration include contact with the door knob 14 in the room, opening of the door 14 from the room, and the like.

FIG. 4 is an explanatory view showing a third embodiment of the present invention. In this embodiment, the entrance detection means (exit detection means) 31 is laid in the place going up from the entrance 32, and comes into contact with or passes over the entrance from the entrance 32 toward the room. Is detected and the air conditioner 11 is operated. When the entry detection unit 31 is used as the exit detection unit, it may be detected that the entrance passing from the room toward the entrance. A plurality of sensors may be laid along the passage to determine whether to enter or leave the room.

FIG. 5 is an explanatory view showing a fourth embodiment of the present invention. In this embodiment, a signal can be wirelessly transmitted from the transmitting device 42 carried by the user 41 to the receiving device 43 to operate the air conditioner 11 before entering the room. The method of sending the signal may be that the user 41 intentionally operates the transmitting device 42 to transmit an operation command to the receiving device 43, or that the transmitting device 42 approaches a certain distance and continues to approach. The air conditioner 11 may be operated by detecting by the receiving device 43 and predicting entry. In the latter case, there is a possibility of a malfunction, so a confirmation signal may be sent from the receiving device 43 to the transmitting device 42 to request a response from the user 41.

On the other hand, in the case of leaving the room, the receiving device 43 may detect that the transmitting device 42 moves away,
The air conditioner 11 may be stopped intentionally.

FIG. 6 is a flowchart of a method for stopping an air conditioner according to the present invention. The configuration of this figure is the same as that of FIG.
The movement of the user is detected by the exit detection unit 51, and whether or not to exit is determined by the exit determination unit 52. Then, the configuration is such that the air conditioner is stopped when it is determined to leave the room.

In the above embodiments, the general air conditioner has been described. However, the present invention can be applied to an absorption refrigeration system and an absorption refrigeration system in addition to a compression air conditioner.

Further, each of the entry detection means and the exit detection means may be combined with a plurality of detection means, thereby making it possible to significantly reduce malfunction.

[0021]

According to the present invention, the user no longer taste discomfort immediately after entry, Ru is released from the hassle of operating the air conditioner after entry.
