Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem in an outdoor unit of an air conditioner that the shape of an outside air temperature sensor holder must be designed according to a difference of diameters of pipes of the heat exchanger or specifications of the heat exchanger. <P>SOLUTION: Since this outdoor unit of the air conditioner has a locking portion 1a attachable to the heat exchanger and applicable to any specification of the heat exchanger, that is, any dimension with respect to the difference of pipe diameters and difference of dimensions from the fin edge of the heat exchanger to the pipe, the outside air temperature sensor holder 1 can be used in commonl though it has been individually designed according to the specifications of the heat exchanger. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an outdoor unit of an air conditioner, and more particularly to an outside air temperature sensor holder.

  Conventionally, in an outdoor unit of an air conditioner, the outside air temperature sensor holder is inserted between the fins of the heat exchanger of the outdoor unit and locked so as to sandwich the pipe of the heat exchanger. At this time, the locking portion of the outside air temperature sensor holder is designed to have a shape and a dimension that exactly match the diameter of the pipe and the pitch between the pipes.

  5 to 7 are a perspective view of a locking portion of an outside air temperature sensor holder, a perspective view of the whole outdoor unit of the air conditioner, and a perspective view of an outside air temperature sensor holder of a conventional air conditioner.

  As shown in the figure, the outside air temperature sensor holder 11 has an engaging portion 11a inserted between the fins of the heat exchanger 2 of the outdoor unit, and the engaging portion 11a is connected to the diameter of the pipe 2d of the heat exchanger 2 and the pipe. The piping was pinched and locked so as to exactly match the pitch between them.

Conventionally, the outside air temperature sensor holder fixing is provided with a locking portion that matches the pipe diameter or the heat exchanger.

  However, in the conventional configuration, the outside air temperature sensor holder is required due to the difference in the pipe diameter and the configuration of the heat exchanger, and the number of similar parts increases, leading to supply of parts and incorrect mounting of parts. Had.

  In addition, there is a problem that a loss amount such as die investment and logistics management cost occurs.

  The present invention solves the above-described conventional problems, and includes a locking portion that absorbs a difference in pipe diameter and a difference in the configuration of a heat exchanger, and a shape that sandwiches an upper outer part and restricts movement, and has a common part. It aims at providing the outdoor temperature sensor holder fixing method of the outdoor unit of the air conditioner aiming at making it easy.

  In order to solve the above-described conventional problems, the present invention includes a compressor, a blower and an electric component box that stores a control base for controlling the blower, a heat exchanger having a different number of pipe rows or pipe diameters depending on the capacity class, In an outdoor unit of an air conditioner that is provided outside the heat exchanger and includes an outside air temperature sensor that detects outside air temperature and an outside air temperature sensor holder that houses the outside air temperature sensor, the outside air temperature sensor holder is attached to the heat exchanger. Inserted from the back of the exchanger, fixed with the engaging part provided on the pipe and the side surface of the outside air temperature sensor holder, the upper outer part is in contact with the upper part of the outside air temperature sensor holder is there.

  Further, the locking portion is sandwiched between the pipes, and the locking portion has a claw portion having elasticity.

Thereby, it becomes possible to fix without being influenced by the difference in the pipe diameter and the difference in the configuration of the heat exchanger.

  Further, the movement can be restricted by devising the fitting shape with the upper shell part.

  The outside air temperature sensor holder fixing of the present invention can realize part simplification and reduction of mold investment by sharing parts.

  According to a first aspect of the present invention, there is provided a compressor, a blower, an electric component box that houses a control base for controlling these, a heat exchanger having a different number of pipe lines or pipe diameters depending on a capacity class, and an outside of the heat exchanger. In an outdoor unit of an air conditioner provided with an outside air temperature sensor that detects an outside air temperature and an outside air temperature sensor holder that houses the outside air temperature sensor, the outside air temperature sensor holder is inserted from the back of the heat exchanger. The pipe is fixed by a locking portion provided on a side surface of the outside air temperature sensor holder, and the upper outer part is in contact with the upper part of the outside air temperature sensor holder.

  In the second invention, in particular, the locking portion of the first invention is sandwiched between pipes, and the locking portion has a claw portion having elasticity.

  According to a third aspect of the invention, the outside air temperature sensor holder of the first aspect of the invention is provided with a groove portion for sandwiching the upper outer shell part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 to 4 are perspective views of a locking portion of an outside air temperature sensor holder according to the present invention, a perspective view of a fitting state between the outside air temperature sensor holder 1 and an upper outer part, and an overall outdoor unit of the air conditioner. It is a perspective view and a perspective view of the outside air temperature sensor holder.

  FIG. 1 shows an outside air temperature sensor holder 1 held in a heat exchanger 2 according to the first embodiment of the present invention, and is provided with a locking portion 1a for sandwiching a pipe 2d.

  FIG. 2 shows the upper shell part 3 according to the first embodiment of the present invention, and a folded portion 3 c that fits the outside air temperature sensor holder 1 is provided.

  With the above configuration, the movement of the outside air temperature sensor holder 1 can be regulated.

  As described above, the outdoor unit of the air conditioner of the present invention can realize the simplification of parts management and the reduction of mold investment by sharing the parts attached to the heat exchanger. It can be applied to products having a heat exchanger.
