Definitions

  • the present disclosure relates to an air conditioner having a filter in an air intake section.
  • an air conditioner has a housing that constitutes the outer shell of the air conditioner, and a heat exchanger and a blower that are arranged inside the housing.
  • the housing is formed with a suction section through which air flows into the housing from the outside by driving the blower, and a blow-out section through which the air flowing out of the housing passes.
  • An air conditioner has a filter disposed in an air suction portion, and the filter filters air sucked into a housing (see, for example, Patent Document 1).
  • the air conditioner can prevent dirt from accumulating inside the housing by including a filter in the suction unit.
  • An air conditioner equipped with a filter as in Patent Document 1 is provided with a filter guide for fixing the filter to a heat exchanger or a suction panel that covers the suction part from the outside of the filter, and the filter is fixed to these. Further, in an air conditioner provided with a filter, each filter is fixed to a housing using fixing parts such as screws. Washing and cleaning the inside of the air conditioner is often troublesome, and if it is not easy to attach and remove the filter, it is not easy to clean the heat exchanger arranged inside the air conditioner. Therefore, there is a demand for an air conditioner in which the filter can be easily attached to and removed from the housing, and the heat exchanger can be washed and cleaned easily.
  • An object of the present disclosure is to solve the above-described problems, and to provide an air conditioner in which the filter can be easily attached to and removed from the housing.
  • An air conditioner includes an air blower, a heat exchanger that exchanges heat between a refrigerant flowing inside and air supplied by the air blower, an intake section into which air is sucked, and air is blown out.
  • At least one filter panel having a housing formed with a blowout section and accommodating therein a blower and a heat exchanger, and a filter disposed in the suction section and filtering air flowing into the housing.
  • the suction part has a filter fixing part for fixing at least one filter panel
  • the filter fixing part penetrates the plate-shaped filter support part and the filter support part, and the filter support part and a shaft for rotatably supporting the filter support, the upper part of the filter support being rotatably supported by the shaft, and at least one filter panel being arranged in the suction section.
  • the lower part of the filter support part faces all the filter panels of at least one filter panel from the outside of the housing, and the width of the plate is formed larger than the upper part of the filter support part.
  • the air conditioner includes at least one filter panel having a filter and arranged in the suction section to filter air flowing into the interior of the housing.
  • the suction section also has a filter fixing section for fixing at least one filter panel.
  • the filter support portion of the filter fixing portion is suspended by the shaft portion, and the upper portion of the filter support portion is rotatably supported by the shaft portion.
  • the filter support portion of the filter fixing portion faces all of the at least one filter panel from the outside of the housing when the at least one filter panel is arranged in the suction portion.
  • the width of the plate is formed such that the lower portion of the filter support portion is wider than the upper portion of the filter support portion.
  • the lower portion of the filter support portion is heavy, and the filter support portion is arranged at a position facing the filter panel due to the weight of the filter support portion itself.
  • the user does not need to fix the filter panel to the suction part of the housing with fasteners such as screws when arranging the filter panel on the suction part. Further, the user can attach and detach the filter panel only by rotating the filter support. Therefore, the user can easily attach the filter to the housing and remove the filter from the housing.
