Description

  The present invention relates to the outside of an air conditioner, and more particularly to a temperature sensor holder for detecting outside air temperature.

  Some outdoor units of an air conditioner are composed of components as shown in FIG. 3, for example. The main body of the outdoor unit is composed of a substrate 1, a front grill 2, an outer box 3 (outer box right side 3a, outer box left side 3b), and an upper plate 4. The inside of the main body is a compressor 5 (see FIG. (Not shown), a heat exchanger 6 bent in an L shape and disposed on the back of the substrate, a blower 7 provided on the downstream side of the heat exchanger 6, and an electrical component box 108 containing electrical components The temperature sensor 109 for detecting the outside air temperature is disposed on the outer upper portion of the heat exchanger 6, and the signal line 110 of the temperature sensor 109 is held by a holder 11 that is locked to the heat exchanger 6. It is like that.

  In the above configuration, for example, an invention that is attached to an electrical component box is disclosed as an invention relating to the attachment of the temperature sensor 109 that detects the outside air temperature.

4 to 5 are configuration diagrams of the conventional invention. As shown in the figure, the signal line 110 of the temperature sensor 109 extended from the back side of the electrical component box 108 is attached to a holder 111 provided on the back side of the electrical component box 108 so as to be rotatable. In addition, an example is disclosed in which the holder 111 is rotated until it is substantially perpendicular to the front surface of the heat exchanger 6 after the electrical component box 108 is attached (see, for example, Patent Document 1).

  However, in the configuration of the conventional invention, since the sensor holder and the electrical component box are separated from each other, the number of parts increases, and an operation of attaching the holder to the electrical component box also occurs. Further, due to the structure to be rotated, the structure of the joint between the sensor holder and the electrical component box holder becomes complicated. In addition, it takes a long time to rotate the holder until it is almost perpendicular to the front surface of the heat exchanger when the sensor is assembled, and there is a problem that the sensor cannot detect the outside air temperature if the work is not performed reliably. Arise.

  The present invention solves the above-described conventional problems, does not increase the number of parts, does not require the work of attaching the sensor holder to the electrical component box, and facilitates the structure of the sensor holder and the junction of the electrical component box. It is an object of the present invention to provide a holder for an outside air temperature sensor of an air conditioner that can improve assembly and can hold the sensor accurately at an appropriate position.

  In order to solve the conventional problems, an outdoor unit of an air conditioner of the present invention is an air conditioner provided with an outer box, a heat exchanger placed inside the outer box, and an electrical component box. In the outdoor unit, the electrical component box has a first tongue portion and a second tongue portion on its outer shell, and a sensor holding portion is provided on the first tongue portion, and the sensor holding portion and the electrical component An upper end portion of the heat exchanger is sandwiched between the outer casing of the product box, and the second tongue is in contact with the upper end of the heat exchanger to support the electrical component box. It is what.

  As described above, according to the present invention, the present invention solves the above-described conventional problems, does not increase the number of parts, and does not require the work of attaching the sensor holder to the electrical component box. The structure of the joint part of the electrical component box is also facilitated to improve the assemblability. Further, it is not necessary to perform an operation for rotating the holder until it is substantially perpendicular to the front surface of the heat exchanger when the sensor is assembled, and the sensor can be accurately held at an appropriate position.

  1st invention is an outdoor unit of the air conditioner which provided the outer box, the heat exchanger mounted in the said outer box, and the electrical component box, Comprising: The said electrical component box is in the outer shell The first tongue portion has a first tongue portion and a second tongue portion, and a sensor holding portion is provided on the first tongue portion, and an upper end portion of the heat exchanger is provided between the sensor holding portion and the outer shell of the electrical component box. The second tongue is in contact with the upper end of the heat exchanger and supports the electrical component box, for example, without increasing the number of components and the sensor holder. There is no work of attaching to the box, and the structure of the joint of the sensor holder and the electrical component box can be facilitated to improve the assemblability.

  According to the second invention, in particular, the sensor holding part of the first invention has a claw part, and the first tongue part has a receiving part fitted to the claw part so that they can be attached to and detached from each other. For example, the problem that the sensor cannot detect the outside air temperature without working to rotate the holder until it becomes almost perpendicular to the front surface of the heat exchanger at the time of assembling the sensor is solved. . In addition, the sensor holding part has a claw part, and the outer part of the electrical component box has a receiving part that fits into the claw part. By separately transporting and storing the parts, the transport and storage efficiency is improved, and a larger number of units can be stored with the same volume.

  In the third invention, in particular, the operation of attaching the sensor holder to the electrical component box, for example, by making the distance between the outer shell of the electrical component box and the sensor holding portion of the first and second inventions substantially equal to the thickness of the heat exchanger. In some cases, the sensor holder can be securely fixed at a position where the sensor can detect the outside air temperature without working to rotate the holder until it is substantially perpendicular to the front surface of the heat exchanger.

  The fourth aspect of the invention is characterized in that a signal line holding part for locking the signal line of the sensor is provided on at least the upper surface of the sensor holding part of the first to third aspects of the invention. In addition, it is possible to facilitate the storing operation of the signal line of the sensor and to prevent the signal line from being damaged and disconnected at the metal tip of the heat exchanger.
