In Patent Document 1, a bottom panel is provided over the entire lower portion of the housing, but since the bulging wall portion is formed on the bottom panel, the volume of the oil storage chamber in which oil is actually stored becomes small. . In order to store a predetermined amount of oil, it is necessary to enlarge the entire bottom panel, which leads to an increase in the size of the air conditioner. In addition, since the bottom panel has a plurality of irregularities and holes, the structure is complicated and the cost is increased.
An object of the present invention is to provide an air conditioner that can be reduced in size and that can store a predetermined amount of oil below the engine and that can reduce costs.

  In order to solve the above-described problems, the present invention is configured such that a housing is partitioned into a heat exchanger chamber and a machine chamber, a heat exchanger and a blower are disposed in the heat exchanger chamber, and a compressor and a compressor are disposed in the machine chamber. In an air conditioner in which an engine for driving a machine is arranged, an engine support for supporting the engine and an oil receiver located below the engine are formed in a lower part of the casing forming the bottom of the machine room.

  According to the present invention, an engine support for supporting an engine and an oil receiver positioned below the engine are provided at a lower part of a casing forming the bottom of the machine room, and the oil receiver is provided below the engine support. Since it has a capacity to store the total amount of engine oil in the engine oil circulation path provided in the housing, the capacity of the oil receiver can be set without being affected by the engine support, and the volume of the oil receiver can be increased As a result, the engine oil can be stored up to the full amount. As a result, when a predetermined amount of engine oil is stored in the oil receiver, the area of the oil receiver can be made smaller than before and the air conditioner can be made smaller. Further, by making the engine support and the oil receiver separate, it is not necessary to provide a connection structure or the like between the engine support and the oil receiver, each structure can be simplified, and the cost can be reduced.

Thus, by making the mounting plate 153 and the mounting plate 154 different in shape, the strength and rigidity of the mounting plates 153 and 154 can be made different, and the gas engine 17 (see FIG. 6A) is supported. Each support position can be favorably supported according to the support position.

In FIG. 5 and FIG. 7B, the support legs 166 are provided in total, that is, two at the front portion and the rear portion of the mounting plate 153 and two at the front portion and the rear portion of the mounting plate 154.

The receptacle 192 is disposed below the mounting plates 153 and 154 and has a capacity for storing the total amount of engine oil in the engine oil circulation path provided in the housing 11.

According to this configuration, by disposing the oil receiver 192 below the mounting plates 153 and 154, the volume of the oil receiver 192 can be increased, and the total amount of engine oil can be stored at the maximum. As a result, when a predetermined amount of engine oil is stored in the oil receiver 192, the area of the oil receiver 192 can be made smaller than before, and the outdoor unit 10 (see FIG. 1) can be made smaller.
Further, by providing the mounting plates 153 and 154 and the oil receiver 192 separately, it is not necessary to provide a connection structure or the like between the mounting plates 153 and 154 and the oil receiver 192, and each structure can be simplified. Therefore, the cost of the mounting plates 153 and 154 and the oil receiver 192 can be reduced.

Further, as shown in FIGS. 2, 5 and 6A, the lower casing 31 is positioned below the refrigerant pipe group 84 as the refrigerant pipe disposed in the casing 11 (see FIG. 1). Since the drain water receiver 193 is provided side by side on the oil receiver 192, the maintenance of the drain water together with the engine oil can be performed, and the maintainability can be improved.
Further, as shown in FIG. 7A, a support support that supports at least one of the oil receiver 192 and the drain water receiver 193 between the oil receiver 192 and the drain water receiver 193 in the lower housing 31. Since the bottom plate support member 188 as a member is arranged, at least one of the oil receiver 192 and the drain water receiver 193 can be supported, and the oil receiver 192 and the drain water receiver 193 can be prevented from bending.

  Also, as shown in FIGS. 4, 5, 6 (A), 6 (B) and 7 (B), a pair of mounting plates 153 and 154 are provided, and an engine support member 156 as a support is provided respectively. Since the gas engine 17 is elastically supported, the shapes of the mounting plates 153 and 154 (for example, the widths W1 and W2 of the mounting plates 153 and 154) are made different according to the shape and weight of the portion where the gas engine 17 is supported. be able to. Thereby, optimization of an engine support structure can be aimed at and cost can be reduced.

  In addition, since a plurality of engine support members 156 are provided and at least one of the vibration isolation rubbers 168 and 169 constituting the engine support member 156 is a liquid seal type, by using the liquid seal type vibration isolation rubber 169, gas can be obtained. The suppression effect which suppresses that the vibration of the engine 17 is transmitted to the housing 11 and each component in the housing 11 can be enhanced. Thereby, slack and damage of each part of the outdoor unit 10 due to vibration can be prevented, and generation of noise can be suppressed.

  The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention.
