Abstract

PROBLEM TO BE SOLVED: To make it possible to detect easily the humidity of a room with high accuracy and protect a sensor so that dust may not accumulate thereon easily by mounting a humidity sensor on a component which is mounted to guide to a condensation receiving pan condensation water deposited on a pipe which constitutes a cycle on the side surface of a heat exchanger and laying out the sensor near an air supply passage. SOLUTION: An indoor unit of a separate type air conditioner houses a heat exchanger 6 which heat-exchanges with an indoor air, a once-through fan which is laid out inside and designed to circulate air, a condensation water receiving pan 4 which receives condensation water deposited on the heat exchanger and a pipe cover 5 which is mounted on the side surface of an end plate 6a of the heat exchanger so as to guide condensation water deposited on a bend pipe 6b of the heat exchanger or the like in a casing component, such as a cabinet 1 or a decorative frame 2. In this case, a humidity sensor 7c is mounted on the front surface of the pipe cover 5 mounted on a hair pin pipe 6b of the heat exchanger partitioned with the decorative frame from the front surface of the heat exchanger 6 and near an air supply passage, thereby enhancing the detection accuracy of humidity.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structure for mounting a humidity sensor of an air conditioner.

[0002]

2. Description of the Related Art In recent years, there has been an increasing need for humidity control by an air conditioner to improve comfort. Therefore, in order to respond to such needs, not only a conventional temperature sensor for sensing the air temperature in a room and a cycle temperature but also full-scale humidity control using a humidity sensor is being performed. FIG. 3 shows an indoor unit of a separate type air conditioner. A heat exchanger 6 for exchanging air in the room and a cross-flow fan (not shown) for circulating the air inside the heat exchanger 6. Heat exchanger end plate 6a to guide to saucer
Pipe cover 5 attached to the side surface, electrical equipment 3 for controlling operation, motor for driving through-flow fan (not shown)
Such parts are housed in the cabinet parts of the cabinet 1 and the decorative frame 2. When a humidity sensor is attached to this air conditioner, as shown in JP-A-5-296486, the humidity sensor is attached inside the electric component together with a weak electric component such as a light receiving element of a remote controller, or 7b, and the support arm 8 is connected to the electric component.
7a which was attached to the front of the heat exchanger through such a component.

[0003]

Here, in the case where the electric component is mounted inside the electric component, the influence of the heat generated by the electric component itself and the humidity of the stagnant air which is away from the air flow path are detected to obtain an accurate value. There is a problem that it is difficult to detect humidity, and when it is attached to the front of the heat exchanger via an arm-shaped part, projections appear when handling electrical components, so there are problems with strength and difficulties in packing. was there. In addition, since the filter is mounted in the middle of the ventilation path, dust finer than the filter can easily adhere to the element of the humidity sensor, and the detection accuracy of the sensor deteriorates within a short period of time.

[0004]

SUMMARY OF THE INVENTION In order to solve these problems, the present invention provides a humidity sensor mounted on a part attached to a side of a heat exchanger for guiding dew condensation water attached to a pipe constituting a cycle to a dew tray. Is attached, and is arranged near the ventilation path.

[0005]

FIG. 1 shows an indoor unit of a separate type air conditioner. A heat exchanger 6 for exchanging air in the room and a cross-flow fan (not shown) for circulating air inside the dew tray 4 for receiving dew water attached to the heat exchanger, dew condensation for the heat exchanger bend pipe 6b, etc. Parts such as a pipe cover 5 attached to the side surface of the heat exchanger end plate 6a for guiding to the tray, electric components 3 for controlling the operation, and a motor (not shown) for driving the through-flow fan are a cabinet 1, a decorative frame 2, and the like. It is housed in a housing component. The present invention employs a humidity sensor 7c on the front surface of the pipe cover 5 as shown in FIG.
Is installed.

A section of the indoor unit of the air conditioner to which the humidity sensor is attached is a cross section, and a pipe cover attached to a heat exchanger hairpin pipe 6b at a position separated from a front surface of the heat exchanger 6 by a decorative frame. 5 is provided with a humidity sensor 7c on the front surface. Also, this makeup frame 2
There is a suction hole 2 in front of the humidity sensor that sucks indoor air.
a is empty.

[0007]

According to the present invention, as shown in FIG. 2, due to the differential pressure of the main flow 9a of the wind, the branch 9b having a lower wind speed than the suction hole 2a of the decorative frame constantly flows during operation, and the humidity in the room is accurately detected. It is easy to be attached, and since it is attached to a position deviated from the mainstream of the air flow path, it is difficult for dust and the like to adhere. Further, since an arm-shaped component is not required, the cost is reduced, and the handling of electric components is facilitated.
