Description

  In the present invention, two types of heat exchangers with different heating media forming an air passage connected to the back side of the suction port for taking in air provided on the front surface of the main body are brought into close contact in series along the air flow direction. The present invention relates to an air conditioner that is provided and blows processing air from a blowout opening that is connected to an air passage.

  For example, there is an air conditioner that incorporates a heat exchanger that forms part of a heat pump and a heat exchanger that forms part of a hot water circulation system along the air flow direction. These two types of heat exchangers are difficult to adopt a single unit structure due to the difference in the heat medium, and are closely assembled in series with the air passage. The upstream heat exchanger is incorporated behind a suction port provided on the front surface of the main body, and an air filter is provided at the suction port so that dust does not enter the machine. However, in actuality, dust may pass through the air filter or dust may enter the machine through a slight gap and accumulate on the two heat exchangers. When dust accumulates on the heat exchanger, there are problems that the air volume decreases and the cooling / heating capacity decreases, or the dust accumulated during cooling or dehumidifying operation contains moisture, and water drops dripping from an unexpected position, leading to water leakage. Therefore, after a certain amount of operation time has elapsed, as shown in Patent Document 1, the heat exchanger is cleaned and maintained.

JP 2006-10178 A

  In an air conditioner in which two types of heat exchangers are assembled in close contact in series along the air flow direction, cleaning and cleaning of the front side of the upstream heat exchanger can be performed from the air inlet from which the air filter is removed. Although it can be performed, the front side of the downstream heat exchanger and the back side of the upstream heat exchanger cannot be cleaned or cleaned unless the entire heat exchanger is removed from the main body. In order to remove the entire heat exchanger for cleaning and cleaning, it is necessary to remove the heat medium from each heat exchanger and remove the heat medium piping. I can't do it.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide an air conditioner in which two types of heat exchangers are closely connected in series along the air flow direction.

  According to the present invention, the front side of the upstream heat exchanger A is cleaned and cleaned from the opened suction port, and the upstream heat exchanger A is released from the downstream heat exchanger B by releasing its close contact state. If it is turned to the suction port side, the front side of the downstream heat exchanger B and the back side of the upstream heat exchanger A can be left without any special support from the suction port so that they can be cleaned and cleaned. After cleaning and cleaning, if the heat exchanger A is rotated and engaged with the heat exchanger B, the original assembled state is obtained.

  In the air conditioner of the present invention, two types of heat exchangers A and B having different heat mediums, which form an air passage connected to the back side of a suction port for taking in air provided on the front surface of the main body, are arranged in the air flow direction. The working air is blown out into the room from a duct-connectable outlet provided in a main body connected to the air passage. A removable decorative grille and an air filter are attached to the suction port on the front surface of the main body. The suction port from which the decorative grille and the air filter are removed is a rectangular opening at approximately the center of the front surface of the main body, approximately equal to the width of the main body and approximately 1/3 of the vertical dimension of the main body. The downstream heat exchanger B constitutes a hot water circulation system using hot and cold water as a heat medium, and is fixed to the main body by screws and suspension means.

  The heat exchanger B is configured to have a substantially right-angled isosceles triangle, a substantial heat exchanger is assembled to the slope structure portion, and the back side is an air passage that continues to the air outlet. The heat exchanger A on the upstream side is a heat exchanger that constitutes a heat pump cycle, and is pivotally attached at a lower portion thereof so that a predetermined range can be rotated in the direction of the suction port in a vertical plane with respect to the heat exchanger B. Has been. The upper part of the heat exchanger A is screwed to the main body and the heat exchanger B. The heat exchanger B and the heat exchanger A are brought into close contact with each other with high accuracy and guide the air from the suction port to the air outlet. The projected plane areas of the heat exchangers A and B are slightly smaller than the plane area of the suction port, and the heat medium pipes are piped from one side to the lower side so as not to line up on the same vertical plane. A chamber is formed in the upper part of the heat exchangers A and B of the main body, and a blower is assembled in this chamber.

  According to the present invention, the front side of the upstream heat exchanger A is washed and cleaned from the suction port opened by removing the decorative grille and the air filter, and the upstream heat exchanger A is converted into the downstream heat exchanger. If the screw is removed from B, the close state is released, and the suction side is rotated using its own weight, the front side of the downstream heat exchanger B and the rear side of the upstream heat exchanger A are It can be washed and cleaned from the suction port. After cleaning and cleaning, the heat exchanger A is turned to the heat exchanger B side and engaged, and if it is screwed, the original assembled state is obtained and the maintenance is completed. Although the heat medium pipe is stressed by the rotation of the heat exchanger A, the heat medium pipe is long in the vertical direction, and usually this level of stress is allowed. About this point, the heat medium piping can also be devised so that no stress is applied even by the rotation of the heat exchanger A.
