Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in a mounting structure of a closing valve in an outdoor unit of an air conditioner.

(Prior Art) As a separate type air conditioner configured by connecting an outdoor unit and an indoor unit, for example, there are those shown in FIGS. 4 and 5. In these drawings, the air conditioner 50 includes a compressor 32, a four-way switching valve 33, an outdoor heat exchanger 34, an expansion valve 36, a first closing valve 37, an indoor heat exchanger 40, a second closing valve 38.
And a refrigeration cycle 49 in which the four-way switching valve 33 is connected by piping to fill the refrigerant, and further, an outdoor fan 35 for the outdoor heat exchanger 34 and an indoor fan 41 for the indoor heat exchanger 40.
And an indoor cabinet 39 including the indoor fan 41 and the indoor heat exchanger 40 of the refrigeration cycle 49, the components other than the indoor heat exchanger 40 of the refrigeration cycle 49 32, 33, 34, 36, 37, 38 and the outdoor fan The outdoor cabinet 31 having 35 is provided. The indoor unit A is configured by including the various elements in the indoor cabinet 39 as described above, and the outdoor unit B is configured by including the various elements in the outdoor cabinet 31.

Then, by switching the four-way switching valve 33, a cooling and heating cycle is formed. In addition, 46 and 47 are connection pipes that connect the internal cabinet 39 internal part and the outdoor cabinet 31 internal part of the refrigeration cycle 49, and 42 to 45 are the respective connection parts.

The respective closing valves 37, 38 in the outdoor unit B were attached to the side plate 48 of the outdoor cabinet 31 in a fixed state inclining in advance at a constant angle (or in the vertical direction or the horizontal direction). On the other hand, the outdoor unit B31 is installed not only on the outdoor floor surface but also on various surfaces such as the wall of the house, the roof, and the balcony of the condominium (suspended). This is a pipe connection that causes the connection pipes 46 and 47 connected to the pipes and 38 to be forcibly bent, which is a construction problem. Also, when the pipe is bent in such a bent state, it does not look good.

(Purpose of the Invention) The present invention has been made in view of the above-mentioned points, and the piping work is easy regardless of the direction in which the piping is connected to the indoor unit side, and the piping can be made to look good. An object is to provide an outdoor unit of an air conditioner.

In order to achieve the above-mentioned object, the present invention comprises a compressor, a heat exchanger, an expansion valve, a first closing valve and a second closing valve, and the first closing valve and the second closing valve. In the outdoor unit of an air conditioner configured by arranging a valve on an outer surface of a cabinet, the first closing valve and the second closing valve are fixedly mounted on a circular valve mounting plate, and the valve mounting plate Is rotatably attached to the outer surface of the cabinet of the outdoor unit, and each of the first closing valve and the second closing valve is provided with a connecting pipe so as to extend to the inside of the device. A third closing valve and a fourth closing valve are attached to the respective connection sides inside the device to which the respective parts are connected.

According to the above configuration, the circular valve mounting plate is rotatably mounted on the outer surface of the cabinet of the outdoor unit in an appropriate direction at an arbitrary rotational position, so that the mounting directions of the first and second closing valves are appropriately set. This enables piping connection to the indoor unit side in an appropriate direction, and
Since the valve mounting plate is circular, it can be mounted at any position in the rotational direction.

Further, the above-mentioned pipe connecting work can be performed in a state where the third and fourth closing valves are closed.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a configuration diagram showing the overall configuration of the air conditioner, and FIG. 2 is a plan view showing the internal configuration of the outdoor unit.

In these drawings, the air conditioner 27 includes a compressor 2, a four-way switching valve 3, an outdoor heat exchanger 4, an expansion valve 6, and a first closing valve 1.
1. Refrigeration cycle 28 in which the indoor heat exchanger 16, the second closing valve 12 and the four-way switching valve 3 are connected and filled with the refrigerant, the outdoor fan 5 for the outdoor heat exchanger 4, and the indoor heat exchanger 16 Indoor fan 17 for, an indoor cabinet 15 to which the indoor fan 17 and the indoor heat exchanger 16 of the refrigeration cycle 28 are attached, and the above-mentioned constituent elements 2, 3, 4, other than the indoor heat exchanger 16 of the refrigeration cycle 28, 6, 11 and 12 and an outdoor cabinet 11 to which the outdoor fan 5 is attached. An indoor unit A is configured by including various elements in the indoor cabinet 15, and an outdoor unit by including various elements in the outdoor cabinet 1. B is configured, and its basic configuration is similar to that shown in the conventional example.

Next, the characteristic configuration of the outdoor unit B of the present invention will be described.

As shown in FIG. 3, the two closing valves 11 and 12 are mounted on a circular valve mounting plate 22 by bolts 23 and 23. This valve mounting plate 22 is screwed so as to be positioned in an appropriate rotation direction in both directions of the side panel 22a in a state of being fitted into a circular mounting opening 22b provided in the side panel 22a of the outdoor cabinet 1 of the outdoor unit B. Fixed by 24. Side panel
A flange 22c is provided on the inner edge of the circular mounting opening 22b of 22a, and the flange 22c is provided with a mounting long hole which does not appear in the figure, and each screw is provided at an appropriate position of the appropriate long hole. By fixing 24, the valve mounting plate 22 is mounted so that the closing valves 11 and 12 are oriented in appropriate directions. 12a is a service port for air purging.

In the embodiment shown in FIG. 3, the valve mounting plate 22 is attached so that the connecting flare nuts 13 and 14 located at the ends on one side of the closing valves 11 and 12 are directed rearward. The valve mounting plate 22 may be attached so that the flare nuts 13 and 14 face upward or downward in correspondence with the direction in which the connection pipes 29 and 30 from A reach the outdoor unit B.

Further, connection pipes 25 and 26 integrally provided with flexible portions 25a and 26a are provided on the sides of the both closing valves 11 and 12 connected to the inside of the outdoor unit B, and the connection pipes 25 and 26 are provided.
