Definitions

  • the present disclosure relates to a pipe setting structure, and an indoor unit of an air-conditioning apparatus, which include a back housing that accommodates a pipe or pipes, and a cover attached to the back housing.
  • an indoor unit is provided with only one space for accommodation of a pipe (see, for example, Patent Literature 1).
  • Patent Literature 1 Japanese Unexamined Patent Application Publication No. 2005-106397
  • Patent Literature 1 in the case of changing a capacity zone or refrigerant, the models of pipes that can be each set in a pipe accommodation space in an indoor unit are limited. If a pipe has a large diameter, it cannot be accommodated in the pipe accommodation space. If the pipe has a small diameter, it can be accommodated in the pipe accommodation space, but is moved when the indoor unit is installed, since no member that holds down the pipe is provided. Consequently, for example, the pipe is twisted, and thus broken.
  • the present disclosure is applied to solve the above problems, and relates to a pipe setting structure and an indoor unit of an air-conditioning apparatus, in which regardless of whether the number of pipes provided in a refrigeration cycle circuit is one or two and the diameter of the pipe or the pipes, the pipe or pipes can be accommodated and secured.
  • a pipe setting structure includes a back housing, and a cover attached to the back housing.
  • the back housing has a first recess and a second recess.
  • the first recess is recessed from a surface of the back housing, and includes a first back portion.
  • the second recess is adjacent to the first recess and recessed from the surface of the back housing, and includes a second back portion.
  • the second back portion is located closer to the surface of the back housing than the first back portion. Between the first back portion and the second back portion, a step is provided.
  • An indoor unit of an air-conditioning apparatus includes the pipe setting structure as described above.
  • the back housing has a first recess and a second recess.
  • the first recess is recessed from a surface of the back housing, and includes a first back portion.
  • the second recess is adjacent to the first recess and recessed from the surface of the back housing, and includes a second back portion.
  • the second back portion is located closer to the surface of the back housing than the first back portion.
  • a step is provided between the first back portion and the second back portion.
  • Fig. 1 is a refrigerant circuit diagram of an air-conditioning apparatus 100 according to Embodiment 1 of the present disclosure.
  • an outdoor unit 101 and an indoor unit 102 are connected by a gas refrigerant pipe 103 and a liquid refrigerant pipe 104.
  • the outdoor unit 101 includes a compressor 105, a four-way valve 106, an outdoor heat exchanger 107, and an expansion valve 108.
  • the compressor 105 compresses sucked refrigerant and discharges the compressed refrigerant.
  • the operating frequency of the compressor 105 may be arbitrarily changed by, for example, an inverter circuit in order to change the volume of refrigerant that is sent per unit time by the compressor 105.
  • the four-way valve 106 is, for example, a valve that switches the flow of refrigerant between the flow of refrigerant during cooling operation and that during heating operation.
  • the outdoor heat exchanger 107 causes heat exchange to be performed between refrigerant and outdoor air. During the cooling operation, the outdoor heat exchanger 107 operates as a condenser to condense and liquefy the refrigerant. During the heating operation, the outdoor heat exchanger 107 operates as an evaporator to evaporate and gasify the refrigerant.
  • the expansion valve 108 is a flow control valve.
  • the expansion valve 108 reduces the pressure of refrigerant to expand the refrigerant.
  • the expansion valve 108 is, for example, an electronic expansion valve, its opening degree can be controlled in response to an instruction from a controller (not illustrated) or other devices.
  • the indoor unit 102 includes an indoor heat exchanger 109.
  • the indoor heat exchanger 109 allows heat exchange between, for example, the air to be conditioned and refrigerant.
  • the indoor heat exchanger 109 operates as an evaporator to evaporate and gasify refrigerant.
  • the indoor heat exchanger 109 operates as a condenser to condense and liquefy refrigerant.
  • the flow of the refrigerant can be switched by the four-way valve 106 of the outdoor unit 101, whereby the cooling operation or the heating operation can be performed.
  • Fig. 2 is an exploded perspective view of the indoor unit 102 of the air-conditioning apparatus 100 according to Embodiment 1 of the present disclosure.
  • a design panel 1 and a back housing 2 are provided on a front side and a back side of the outer shell, respectively.

  • the indoor unit 102 of the air-conditioning apparatus 100 includes the pipe setting structure 7.
  • the pipe setting structure 7 includes the back housing 2 and the motor attachment component 4 attached to the back housing 2.
  • the single collecting pipe 3 is sandwiched and secured between the back housing 2 and the motor attachment component 4.

  • the contact area between the back housing 2 and the pipe (not illustrated) set in the first recess 21 is reduced, thereby preventing a force from being excessively exerted on the pipe when the pipe is accommodated in and held down by the motor attachment component 4.
  • the second recess 22 is adjacent to the first recess 21 and recessed from the surface of the back housing 2, and includes a second back portion 22a.

Because of provision of the protrusion ridge portions 22b, the contact area between the back housing 2 and the pipe (not illustrated) set in the first recess 21 is reduced, thereby preventing a force from being excessively exerted on the pipe when the pipe is accommodated and held down by the motor attachment component 4.

  • the first recess 21 and the second recess 22 define a rectangular space in which the first back portion 21a, the step 23, and the second back portion 22a are continuous with each other.
  • the first recess 21 is located close to the indoor heat exchanger 109, and the second recess 22 is located farther from the indoor heat exchanger 109 than the first recess 21.
  • the second recess 22 may be located close to the indoor heat exchanger 109, and the first recess 21 may be located farther from the indoor heat exchanger 109 than the second recess 22.

  • one of the pipes 3, 34, and 35 that are of different models can be accommodated and secured in at least one of the first recess 21 and the second recess 22.
  • the pipe accommodation space can flexibly adapt to changing of the model of the pipe 3, 34, or 35 that is made in accordance with changing of the capacity zone or refrigerant. Therefore, regardless of whether the number of pipes for use in a refrigeration cycle circuit is one or two, or the diameter of the pipe or pies, the pipe or pipes can be accommodated and secured in the pipe accommodation space.
  • the air-conditioning apparatus 100 is described above as an example of a refrigeration cycle apparatus. This description, however, is not limitative.
  • the above embodiment can be also applied to another type of refrigeration cycle apparatus such as a refrigerating apparatus or freezing apparatus.
  • the pipe setting structure 7 can be applied to not only the refrigeration cycle apparatus, but a fan, a ventilator, or other apparatuses.
