Description

[Detailed description of the invention]

[0001]

[Industrial application field] This invention does not protrude the back outside
The present invention relates to a window air conditioner that is installed in a window and that can open and close the window in the installed state.

[0002]

2. Description of the Related Art In recent years, many air conditioners for windows have been produced in a thin rear air intake / exhaust type in which the entire air conditioner is housed indoors without the rear surface being exposed to the outside. In addition, Japanese Patent Publication No. 63-
In order to prevent a short circuit in the outdoor intake and exhaust when the user accidentally operates with the window on the back of the air conditioner closed as disclosed in Japanese Patent No. 65858, the outdoor intake air or It was equipped with a window closing detection device that detects the temperature of heat exchange and stops the operation of the compressor.

[0003]

[Problems to be Solved by the Invention] This conventional air conditioner for a window has an extremely high outside air temperature during a cooling operation or is exposed to direct sunlight.
If direct such overheating temperature sensor, the measurement of the temperature sensor despite the air conditioner is performing a normal operation
Because the value is extremely higher than during normal cooling operation,
The control unit is behind the air conditioner even though it is open
There is a problem that the air conditioner stops operation due to erroneous determination that the window is closed .

[0004]

Means for Solving the Problems] This invention is to solve the above drawbacks by focusing on this point, in particular its configuration, the chamber and rear
In a window air conditioner that is installed in a window without protruding outside and can open and close the window in the installed state, a heat exchange sensor that detects a temperature of an outdoor heat exchanger, and a compressor A current sensor for detecting the operating current of the vehicle, and an alarm body provided on the indoor side of the main body, wherein the detection value of the heat exchange sensor is equal to or more than a predetermined value and
When the detection value of the current sensor is equal to or less than a predetermined value, the alarm is turned off.
Activate and stop the operation of the air conditioner.
The detected value of the sensor is equal to or more than a predetermined value and the detection of the current sensor is performed.
When the value is equal to or more than the predetermined value, the operation of the air conditioner is continued .

[0005]

When the air conditioner is operated without forgetting to open the window, first, when the compressor 2, the indoor fan 10, and the outdoor fan 12 operate, the indoor heat exchanger 9 becomes low temperature, and the outdoor heat exchanger 11
Becomes hot, and is blown by the fans 10 and 12, respectively, to start heat exchange. At this time, since the glass door 20 is closed, the hot air discharged from the outdoor air outlet 14 is directly sucked into the outdoor air inlet 13 to cause a short circuit phenomenon, and the outdoor air passage 16 and the outdoor heat exchanger 11 become hot. The current sensor 26 detects that the overload relay 27 attached to the compressor 2 itself has been activated and the compressor 2 has stopped, and the temperature of the outdoor heat exchanger 11 has been detected.
When the temperature of the heat exchanger 11 is 70 ° C. or higher, a signal is sent to the display device 25 to turn on the lamp which is the alarm 24 and to stop the entire air conditioner.

The air conditioner cannot be restarted until the temperature of the compressor 2 drops and the overload relay 27 returns. If the overload relay 27 returns after a few minutes, the glass door 20 is opened and the air conditioner can be restarted. Also, when the outside temperature is extremely high during cooling operation or when
The sunlight directly overheats the heat exchange sensor 17 and the air conditioner is normal.
Of the heat exchange sensor 17
When the constant value is extremely higher than during normal cooling operation
In any case, the overload relay 27 operates and the compressor 2 stops.
Until the current sensor 26 confirms that
The Japanese machine continues normal operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. Reference numeral 5 denotes an outer frame provided with an indoor inlet 6 and an indoor outlet 7 on the front surface. The upper part of the machine room 4 in the outer frame 5 is partitioned into a room side and a room outside by a central partition wall 8. An indoor heat exchanger 9, an indoor fan 10 and the like are provided, and an outdoor heat exchanger 1
1, an outdoor fan 12 and the like are provided. An outdoor air inlet 13 is provided behind the outdoor heat exchanger 11, and an outdoor air outlet 14 is provided next to the outdoor air inlet 13.

The indoor air inlet 6, the indoor heat exchanger 9, the indoor fan 10, and the indoor outlet 7 are communicated with each other so that
The outside air inlet 16, the outdoor heat exchanger 11, the outdoor fan 12, and the outdoor outlet 14 communicate with each other to form an outdoor air passage 16. A heat exchange sensor 17 is attached to the outdoor heat exchanger 11 and detects the temperature of the heat exchanger 11.
Reference numeral 18 denotes a mounting frame for mounting the air conditioner on a window frame 19. 20
Is a glass door. Reference numeral 21 denotes an operation unit provided in front of the outer frame 5 and includes an operation switch 22, a room temperature setting device 23, and a display device 25 such as an alarm 24 using a lamp or the like.

Reference numeral 26 denotes a current sensor for detecting the operating current of the compressor 2. 27 is an overload relay provided in the compressor 2.
When the compressor 2 itself is overheated to a high temperature
Or a lock phenomenon occurred for some reason and an overcurrent flowed
In this case, the power supply to the compressor 2 is stopped to stop the operation.
Stop to prevent the compressor 2 from breaking and when the compressor 2 is stopped
If the temperature drops and the cause of overcurrent is removed,
This is a device that automatically returns to start operation again. Next, a window closing detection method in the window air conditioner will be described. When the air conditioner is operated without opening the window, first, when the compressor 2, the indoor fan 10, and the outdoor fan 12 operate, the indoor heat exchanger 9 becomes low in temperature, and the outdoor heat exchanger 11 becomes high in temperature. It is blown by 10.12 and starts heat exchange. At this time, since the glass door 20 is closed, the hot air discharged from the outdoor air outlet 14 is directly sucked into the outdoor air inlet 13 to cause a short circuit phenomenon, and the outdoor air passage 16 and the outdoor heat exchanger 11 become hot. The current sensor 26 detects that the overload relay 27 attached to the compressor 2 itself has been activated and the compressor 2 has stopped, and the temperature of the outdoor heat exchanger 11 has been detected.
When the temperature of the heat exchanger 11 is 70 ° C. or higher, a signal is sent to the display device 25 to turn on the lamp which is the alarm 24 and to stop the entire air conditioner.

The air conditioner cannot be restarted until the temperature of the compressor 2 drops and the overload relay 27 returns. If the overload relay 27 returns after a few minutes, the glass door 20 is opened and the air conditioner can be restarted. Also, when the outside temperature is extremely high during cooling operation or when
The sunlight directly overheats the heat exchange sensor 17 and the air conditioner is normal.
Of the heat exchange sensor 17
When the constant value is extremely higher than during normal cooling operation
In any case, the overload relay 27 operates and the compressor 2 stops.
Until the current sensor 26 confirms that
The Japanese machine continues normal operation.

[0011]

[Effect of the invention] As described above, according to the invention, heat exchange
Close the window to check not only the temperature of the relay but also the operating status of the overcurrent relay
Since it was incorporated into the conditions of knowledge, the effects of outside temperature and direct sunlight
Malfunction of the window closing detection due to
It became so.
