Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of a heat exchanger that constitutes a cross flow fan type blower circuit used in an air conditioner or the like.

[0002]

2. Description of the Related Art Recently, an indoor unit having a structure as shown in Japanese Patent Laid-Open No. 58-98521 has been known in response to a demand for higher performance of an air conditioner.

On the other hand, recently, a heater having a relatively small capacity is arranged on the downstream side of the heat exchanger because it is simple and effective for reheating during dehumidifying operation and as an auxiliary heat source for heating a heat pump. There are more examples.

Therefore, in order to satisfy the above-mentioned requirements, two heat exchangers are formed in a V shape, and both ends in the axial direction of the cross flow fan are connected by substantially triangular plates, and the two C shapes are formed. There is known an indoor unit having a structure in which it is surrounded by a spacer that blocks between the heat exchangers.

The structure will be described below with reference to FIGS. In FIG. 5 and FIG. 6, an air blowing path is formed between the suction ports 1 and 2 and the blowing port 3, and a grill and an air filter respectively provided in the suction ports 1 and 2 are provided in the air blowing path. Etc., a heat exchanger 4 composed of two heat exchange parts 4A and 4B so as to form a V shape, and a crossflow fan 5 below the heat exchanger 4 are arranged, and the heat-exchanged air crossflows. The fan 5 sends the air to the outlet 3. The heat exchanger 4 having the heat exchange portions 4A and 4B which are independent in the V-shape is
In the configuration in which the axial ends of the cross flow fan 5 are connected by substantially triangular plates 7 and are surrounded by the spacers 6 that block between the two C-shaped heat exchangers 4, the spacers 6 are In order to easily fix the heat exchanger 4 and the substantially triangular plate 7 while keeping the sealing property, the spacer 6 is made of metal, and both ends of the heat exchanger 4 are substantially triangular plate 7.
In many cases, the spacer 6 is fixed to the substantially triangular plate 7 with a screw in order to fix it to the plate 7.

[0006]

However, in the fixing means of the spacer 6 for sealing the above-mentioned V-shaped heat exchanger 4, since it is fixed to the substantially triangular plates 7 at both ends with screws, respectively, the screws are used. Increased the number of parts and installation work time.

The present invention has been made to solve such a conventional problem by improving the fixing means of the spacer 6 for sealing the above-mentioned V-shaped heat exchanger 4 and improving the number of screw parts and mounting work. The purpose is to reduce the increase in time.

[0008]

In order to achieve the above object, the present invention is a heat exchanger in which two heat exchange portions are combined in a V shape in the entire suction direction when viewed from the center of a cross flow fan. With an umbrella, connect the heat exchange parts at both ends in the axial direction of the cross flow fan with a substantially triangular plate, and surround the narrow side of the C-shaped heat exchanger with a spacer. In the configuration, in order to easily fix the spacer to the heat exchanger and the substantially triangular plate while maintaining a sealing property, the spacer is made of metal, and a claw provided at one end of the spacer has a substantially triangular shape. The plate is hooked on a hook portion provided on one side, and the other end is fixed to the other substantially triangular plate by a screw. Therefore, one end of the spacer does not need to be screwed to the substantially triangular plate, and the intended problem can be solved.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is to solve the above-mentioned problems, and the invention according to claim 1 is a cross-flow fan in which a single impeller having a plurality of blades arranged in a cylindrical shape is combined in the rotational axis direction. A stabilizer located in close proximity to the cross flow fan, a guider forming a flow path, an air filter, a suction grill, and a heat exchanger having two independent heat exchange parts. Then, the entire area in the suction direction when viewed from the center of the cross flow fan is covered with a heat exchanger in which the two heat exchange parts are combined in a V shape like an umbrella, and at both ends in the axial direction of the cross flow fan. , A structure in which the heat exchange portions are connected by a substantially triangular plate, and a space between the narrow sides of the C-shaped heat exchanger is surrounded by a spacer, the spacer is formed by the heat exchanger and the substantially triangular shape. Board and The metal to easily fix maintaining Lumpur property, and hook the pawl provided at one end of the spacer hook portion provided on one of the substantially triangular-shaped plate,
Since the other end is fixed to the other substantially triangular plate by the screw, only one screw can be fixed. Further, in the invention according to claim 2, the spacer in the invention according to claim 1 has substantially triangular shapes at both ends. With a hole for hooking the hooking claw on the plate, the spacer fixing screw can be eliminated.

According to the third aspect of the invention, since the spacers are made of resin and fixed to the substantially triangular plates at both ends of the heat exchanger, the spacers are provided at both ends of the substantially triangular plates. Since the hooks are provided with hooks, the screws for fixing the spacers can be eliminated as in the operation of the second aspect of the invention.

Further, in the invention according to claim 4, the spacer is made of resin, and the lower end of the spacer is provided with a hooking claw for fixing to the heat exchanger. The substantially triangular plate has a hole or a hole. The spacer can be fixed without any processing such as nails.
