JP 2000-65391 A (page 3, FIG. 2) JP 2001-182958 A (page 4, FIG. 1)

  Currently, the energy saving of air conditioners, which are considered to be the highest power consumption used in homes, has become a social effort to suppress global warming. Especially in the air conditioner, the air conditioner that is installed with the indoor unit hung on the wall and connected to the outdoor unit has a higher energy-saving regulation value than the other types. Is set. For this reason, as energy saving progressed, the size of heat exchangers and the like increased, and the size and weight of the air conditioner increased. In particular, the one that connects one wall-mounted indoor unit and one outdoor unit is the mainstream form of air conditioner used at home, and the regulation value of the Energy Conservation Law is also among the air conditioners. Higher and higher energy-saving equipment tends to increase in size and increase the width and width of indoor units.

  On the other hand, the housing environment in recent years has been diversified. For example, in the traditional Japanese style room, three-dimensional pillars are often used, and the width of the space for installing the indoor unit of the air conditioner is approximately 818 mm. It is. Furthermore, due to the increasing demand for earthquake resistance, the number of cases using quadrangular columns has increased, and the width of the space in which the indoor unit of the air conditioner can be installed is approximately 788 mm. In addition, for example, in the living room, the case of a large window is increasing due to the demand for interior, and the vertical width of the space for installing the indoor unit of the air conditioner on the window is increasing to approximately 300 mm. Therefore, the installation space of the indoor unit of the air conditioner tends to be reduced. Furthermore, the living room, the dining room, and the kitchen are united, and the walls of the room are becoming smaller and the rooms are becoming larger.

  As described above, as the size of the room increases, the demand for increasing the capacity of the air conditioner increases, and the unit size increases with the energy saving and efficiency. The problem that the indoor unit of the air conditioner cannot be installed on the wall surface is increasing due to restrictions on the horizontal width and / or vertical width of the indoor unit dimensions.

  The present invention has been made to solve the above problems, and a first object is to consider the installation space of the air conditioner in a recent house, and to determine the dimensions of the indoor unit of the air conditioner. It is specified and achieves high energy savings with limited dimensions depending on the shape and configuration of the indoor unit.

  In addition, the second purpose includes pipe connection work that is most difficult to install because installation workability is likely to deteriorate when the indoor unit is installed in the presence of restrictions on the installation of the indoor unit of the air conditioner. It is intended to improve the installation workability.

  In addition, the third purpose is that the wall space from the side of the window to the corner of the room can be opened between three scales as the room structure, and if the dimensions of the indoor unit fit between the three scales, More cases are installed in the corners. In addition, in the corner space of a room, residents often install furniture, telephones and interiors, which increases the difficulty of operating the main unit of the indoor unit. On the other hand, the size of rooms such as living rooms has increased, and the installation of indoor units in the corners of rooms has increased, making it difficult to reach hot and cold air from the air conditioner to every corner of the room. The temperature of the room will be uneven and the comfort will deteriorate. The resident's lifestyle is also increasing as the size of the room increases. For example, the resident's lifestyle is increasing because people move more and more, such as places to relax, places to eat and places to eat. Depending on the situation, there are many cases where the main body of the air conditioner is operated such as the air flow direction and the wind speed, so that the above-mentioned deterioration of comfort is suppressed and the living place of the resident is efficiently and easily air-conditioned. This facilitates the operation of the main body.

  The fourth purpose is that, in the case of an air conditioner, it is usually necessary not only to operate the main body but also to periodically perform filter cleaning, appearance and internal maintenance in order to fully demonstrate the air conditioning capability. However, in installation situations where it is difficult to use, users often spend a lot of time and often do not perform regular maintenance. Since the energy-saving performance is likely to deteriorate due to clogging, it is intended to facilitate regular maintenance operations.

  In addition, the fifth purpose is to increase the number of apartments in the city center. In these apartments, outdoor units have often been suspended from the ceiling of the veranda. Therefore, in order to make it difficult for the outdoor unit to be seen from the outside, the ceiling installation is restricted, and the outdoor unit is often installed on the veranda. Also, in general detached houses, from the viewpoint of aesthetics, since there are many cases where outdoor units are installed on the veranda, the veranda is becoming narrower and there is an increasing demand for downsizing the outdoor unit. Therefore, it defines not only the dimensions of the indoor unit but also the external dimensions for effectively utilizing the installation space in the outdoor unit.

  An air conditioner according to the present invention includes an inverter-driven compressor capable of controlling the rotation speed, a four-way valve, a condensation side heat exchanger, a decompression device, a refrigeration cycle connected to an evaporation side heat exchanger, and a wall-mounted indoor unit In the air conditioner having a form, the indoor unit includes a box body having a suction port on an upper surface or a front surface or an upper surface and a front surface, and a blower port on a lower surface, and indoor air provided in the box body and sucked from the suction port. A cross flow fan that passes the air through the heat exchanger and blows air to the air outlet, and the first horizontal width of the surface in contact with the wall surface on the back side of the indoor unit is different from the second horizontal width of the surface not in contact with the installation wall surface. The first width is 765 mm to 788 mm, the second width is 790 mm to 800 mm, and the height of the indoor unit is 290 mm to 3 mm. It is obtained by the 0mm or less.

  The air conditioner of the present invention includes an inverter-driven compressor capable of controlling the rotation speed, a four-way valve, a condensation side heat exchanger, a decompression device, a refrigeration cycle connected to an evaporation side heat exchanger, and a wall-mounted indoor unit form In the air conditioner having the above, the indoor unit includes a box body having a suction port on an upper surface or a front surface or an upper surface and a front surface and a blower port on a lower surface, and room air provided in the box body and sucked from the suction port.

The first width is 765 mm to 788 mm, the second width is 790 mm to 800 mm, and the height of the indoor unit is 290 mm to 300 mm. Since the width of the surface in contact with the wall surface of the indoor unit is 788 mm or less, it can be installed between three scales using four-dimensional pillars, which is a form of a Japanese-style room increasing in recent years. By making the height dimension of 300 mm or less, it can be installed in the space above the large window often used in the living room. Furthermore, by making the width dimension of the surface not in contact with the wall surface of the indoor unit larger than the width dimension in contact with the wall surface, it is possible to make the intake port of the indoor unit wider, and further, the stacking of the heat exchangers of the indoor unit By adopting a configuration in which the width is increased and the number of loading stages is increased, high energy saving can be realized.

Many of the forms of the veranda are made up of a rectangle consisting of the width facing the dwelling and the vertical width of the dwelling, and the width is often about 30-60% of the width. There are many about 1500 mm. And when installing the outdoor unit on the veranda, if the longitudinal direction of the outdoor unit is installed parallel to the residence, the distance between the outdoor unit and the wall surface of the veranda becomes narrow, and the blast airflow from the outdoor unit becomes the wall surface of the veranda May cause a short circuit that returns to the inlet of the outdoor unit again, or a blown air current may come into contact with the wall surface, causing a wind soaring and causing outdoor dust to soar. There is.

  For this reason, in order to ensure a sufficient distance between the outdoor unit and the wall surface of the veranda, the longitudinal direction of the outdoor unit needs to be installed vertically with respect to the residence. Considering the suction distance 100 mm from the side of the outdoor unit and the piping work space 290 mm, the maximum horizontal width of the outdoor unit needs to be 760 mm or less. Moreover, the height of the wall surface of the veranda is often about 1000 mm to 1200 mm, and the height of the outdoor unit is configured to be approximately ½ or less of the height of the wall surface of the veranda, so that the veranda was looked down from above. Even in the case, it can be a blind spot from the outside. As described above, the size of the outdoor unit is configured such that the maximum width is 760 mm or less and the height is 550 mm or less. Therefore, the outdoor unit can be installed on a veranda of an apartment house or a general detached house. Have.
