Abstract

An electric component box (20) is mounted in a removable manner in the vicinity of a heat exchanger (1) within a cabinet (3). A temperature detector (25) for detecting room temperature is provided integrally to the electric component box (20). The temperature detector (25) is supported in a pivotable manner and can be switched between a detection position at which the temperature detector (25) protrudes from the electric component box (20) and a stowed position at which the temperature detector (25) is close to the electric component box (20). Since the temperature detector (25) does not protrude from the electric component box (20) when at the stowed position, the temperature detector (25) is prevented from being damaged during the conveyance of the electric component box (20). Therefore, the temperature detector (25) is not damaged except during the mounting of the temperature detector (25) to the cabinet (3).

Description

Air conditioner

The present invention relates to an air conditioner in which a temperature detector is installed in a cabinet.

The indoor unit of the air conditioner is provided with a temperature detector that detects the room temperature, and the air conditioning operation is controlled based on the room temperature. The temperature detector is built in the cabinet and installed in front of the heat exchanger. When the air sucked from the suction port passes through the heat exchanger, the temperature detector is touched to detect the room temperature.

If the temperature detector is in the air passage in this way, dust or the like adheres to the temperature detector. Then, the detection accuracy of the temperature detector is deteriorated, and the accurate room temperature cannot be detected. Therefore, in the air conditioner of Patent Document 1, the temperature detector is installed on the side wall surface of the cabinet, and an outside air communication port is formed at a position where a human fingertip touches. The temperature detector is attached to the outside of the electrical component box via an attachment member.

Japanese Patent No. 3887096

The above temperature detector is mounted protruding from the electrical component box. This electrical component box is detachably attached to the cabinet. Here, in a state where the temperature detector is attached to the electrical component box, the electrical component box is transported and attached to and detached from the cabinet. At this time, since the temperature detector is exposed to the outside, the temperature detector may be damaged. For this reason, the electrical component box must be handled with care during transportation and mounting, and workability is deteriorated. Moreover, if the temperature detector is installed on the side surface of the cabinet, dust is less likely to adhere. However, the temperature detector touches the air staying on the side of the cabinet. Therefore, the temperature detector detects the temperature of warm air with little change accumulated near the ceiling. With this, the detection sensitivity of the temperature detector is poor and proper air conditioning operation cannot be performed.

In view of the above, the present invention provides an air conditioner having a structure in which the temperature detector is not damaged except when the temperature detector is mounted on the cabinet, and having a structure in which the detection sensitivity of the temperature detector can be kept good. Objective.

In the present invention, a heat exchanger is provided in a cabinet in which a suction port is formed so as to face the suction port, an electrical box is detachably incorporated in the vicinity of the heat exchanger, and the room temperature is detected in the electrical box. A temperature detector is integrally provided. The temperature detector can be switched between a detection posture protruding from the electrical box and a storage posture close to the electrical box.

¡When the temperature detector is installed in the cabinet, the temperature detector is in the detection position. Except when the temperature detector is attached to the cabinet, the temperature detector is in the stowed position. Thereby, when the electrical unit is transported, the temperature detector does not protrude, so the temperature detector is not damaged.

A filter may be provided at the suction port, the temperature detector may be disposed on the heat exchanger side of the electrical box, and the temperature detector in the detection posture may be positioned between the filter and the heat exchanger. Since air that has passed through the filter touches the temperature detector, dust does not adhere to the temperature detector. Therefore, the detection sensitivity of the temperature detector does not deteriorate.

The temperature detector has a holder for holding the sensor element, the holder is rotatably provided on the electrical box via the rotary shaft, and the lead wire for connecting the sensor element and the electrical box is a hollow rotary shaft. The inside may be wired. As the holder rotates about the rotation axis, the attitude of the temperature detector is switched. The lead wire that passes through the rotating shaft is not twisted and is not broken.

When the temperature detector is in the detection position, the holder is positioned away from the front surface of the heat exchanger, and a buffer is provided between the holder and the heat exchanger so that the holder does not contact the heat exchanger. May be. The buffer is provided in the holder or the heat exchanger, but is preferably provided in the holder for ease of manufacture.

The holder can be opened and closed, and the rotation shaft provided in the holder may be formed of a member divided into two parts. Thereby, a lead wire can be easily passed through a rotating shaft.

A filter guide for holding the filter may be provided in front of the heat exchanger of the cabinet, and the temperature guide positioning unit may be provided in the filter guide. The positioning unit protects the temperature detector so that the temperature detector is not displaced. Therefore, when the filter is removed from the cabinet, the temperature detector is not displaced even if a foreign object hits the temperature detector.

The air conditioner includes a detector that detects an object to be detected related to the control of the air conditioning operation in the cabinet. A built-in unit is detachably provided in the cabinet in the vicinity of a position where it can contact the object to be detected, and a detector is integrally provided in the built-in unit. The detector can be switched between a detection posture protruding from the built-in unit and a storage posture close to the built-in unit. The built-in unit may be other than the electrical box. The detector may be other than the temperature detector.

According to the present invention, since the posture of the temperature detector integrated with the electrical unit can be switched, the risk of the temperature detector being damaged when the electrical unit is transported can be reduced.

Here, the electrical box 20 is detachably incorporated in the cabinet 3. At the time of product assembly or maintenance, the electrical box 20 is transported and attached to and detached from the cabinet 3. Since the temperature detector 25 is provided integrally with the electrical box 20, the temperature detector 25 may be damaged during transportation or attachment / detachment. In order to prevent this damage, the temperature detector 25 has a structure that can be switched between a detection posture protruding from the electrical box 20 as shown in FIG. 11 and a storage posture close to the electrical box 20 as shown in FIG. The

The holder 27 of the temperature detector 25 is rotatably provided on the electrical box 20. As shown in FIGS. 13 and 14, the openable / closable holder 27 includes a holding table 60 that holds the sensor element 26 and a cover 61 that covers the holding table 60. The holding table 60 and the cover 61 are connected so as to be openable and closable, and the cover 27 is locked to a hook 62 formed on the holding table 60, whereby the holder 27 is held in a closed state. In the drawings, FIGS. 5, 7, 9, and 14 show the temperature detector 25 with the cover 61 of the holder 27 open, and the other drawings show the temperature detector 25 with the cover closed. Yes.

The holding base 60 is formed in a flat plate shape, and a long and narrow ventilation hole 63 is formed on the inner side in the left-right direction. Near the outer side of the holding table 60, a fixing portion 64 that sandwiches an end portion on the lead wire side of the sensor element 26 and a guide portion 66 that holds the lead wire 65 connected to the sensor element 26 are provided. The cover 61 is provided with a presser rib 67 that presses the sensor element 26. When the holder 27 to which the sensor element 26 is attached is closed, the sensor element 26 is sandwiched and fixed between the presser rib 67 and the holding base 60. The lead wire 65 is sandwiched and held by the guide portion 66 from the front and rear.

The cover 61 is positioned in front of the holding base 60 so as to face the filter 7 and is formed in a dome shape. A lattice-like vent 68 is formed from the upper part to the lower part of the cover 61. The air sucked from the suction port 4 and flowing between the front cover 12 and the heat exchanger 1 passes through the filter 7 and then enters the front vent 68 from above, below, right and left, and from the rear vent 63. to go out. Air does not stay in the holder 27, and the room temperature that changes from time to time can be detected with high accuracy.

The holder 27 is rotatably provided on the electrical equipment box 20 via the rotation shaft 70. The rotating shaft 70 is formed of two halved

members

71 and 72. A half member 72 is integrally formed on the outside of the holding base 60, and a half member 71 is integrally formed on the outside of the cover 61. A hollow rotating shaft 70 is formed by combining both the

half members

71 and 72 together. Further, as shown in FIG. 13, the holding table 60 and the cover 61 are lowered by one step from the

half members

71 and 72 that form the rotation shaft 70. Thus, the holder 27 and the center of the rotation shaft 70 formed integrally with the holder 27 are displaced in the front-rear direction, and a step is generated between the holder 27, the rotation shaft 70 and the support shaft 74.

The lead wire 65 is guided to the rotating shaft 70 while being held by the guide portion 66 of the holding table 60, and is guided to the outside of the holder 27 through the rotating shaft 70. The lead wire 65 coming out of the holder 27 is wired to the box body 22 along the rear side of the terminal block 24, enters the box body 22 from the guide hole 52 of the lid 33, and is connected to the connector of the circuit board 21. Therefore, even if the holder 27 holding the sensor element 26 rotates, the lead wire 65 does not twist.

The rotation shaft 70 is fitted in a bearing recess 73 provided on the inner surface of the terminal block 24 and is supported rotatably. A support shaft 74 is provided coaxially with the rotation shaft 70. The rotation shaft 70 is provided on the upper portion of the holder 27, and the support shaft 74 is integrally formed on the lower portion of the holding table 60. The support shaft 74 is fitted into a bearing recess 75 provided on the inner side surface of the terminal block 24 and is supported rotatably. Thereby, the holder 27 rotates from the front side toward the rear side around an axis parallel to the vertical direction.

When the temperature detector 25 is in the detection posture, the holder 27 protrudes from the electrical box 20 inward in the left-right direction. When the holder 27 rotates from the detection posture toward the rear side, the holder 27 approaches the electrical box 20 and the temperature detector 25 is in the storage posture. The attitude of the temperature detector 25 can be switched when the electrical box 20 is not attached to the cabinet 3.

When the temperature detector 25 is in the detection posture, the temperature detector 25 is located behind the filter 7 and in front of the heat exchanger 1. If the temperature detector 25 is too close to the heat exchanger 1, the temperature detector 25 is affected by the heat of the heat exchanger 1 and cannot accurately detect the room temperature. Therefore, a buffer body 77 that prevents the holder 27 from approaching the heat exchanger 1 is provided. The buffer body 77 is a leg integrally projecting from the rear surface of the holder 27.

As shown in FIG. 10, the buffer body 77 is located between the holder 27 and the heat exchanger 1. A front end 77 a of the buffer 77 abuts on the front surface of the heat exchanger 1. In addition, the buffer body 77 does not necessarily need to contact the heat exchanger 1 and may be in a close position. When the temperature detector 25 is in the detection posture, the temperature detector 25 and the heat exchanger 1 are kept at a constant distance by the buffer 77. Thereby, the temperature detector 25 does not approach the heat exchanger 1, and the temperature detector 25 can detect the room temperature without being affected by the heat of the heat exchanger 1. In this way, the temperature detector 25 can touch the air that has passed through the filter 7 and can always maintain the temperature detector 25 at a certain distance from the heat exchanger 1, thereby realizing stable and good detection sensitivity. it can.

As shown in FIG. 8, the buffer body 77 protrudes from the holder 27. There is a space behind the terminal block 24. When the holder 27 is rotated about the rotation shaft 70 and the temperature detector 25 is switched to the storage posture, the buffer body 77 enters the space. Therefore, when the temperature detector 25 is switched to the storage posture, the buffer body 77 does not interfere with the storage of the temperature detector 25.

As described above, when the electrical box 20 is transported, the temperature detector 25 is switched to the storage posture. The temperature detector 25 approaches the electrical equipment box 20 and does not protrude greatly from the electrical equipment box 20 as compared with the detection posture. In other words, in the storage posture, the left side of the holder 27 of the temperature detector 25 (the side far from the electrical box 20 in the detection posture) rotates around the rotation shaft 70 and approaches the electrical box 20. The protrusion of the temperature detector 25 itself from the box 20 is reduced. In particular, since there is a step between the rotation shaft 70 and the holder 27, when the temperature detector 25 is in the storage position, the holder 27 can be brought closer to the electrical box 20 side with respect to the rotation center. Further, when the temperature detector 25 rotates, the temperature detector 25 can avoid the interference with the corner of the rear part of the terminal block 24 due to the presence of the step and can rotate smoothly. Therefore, when the electrical box 20 is transported, the probability that an object will hit the temperature detector 25 is reduced, and the temperature detector 25 is less likely to be damaged.

When the temperature detector 25 is attached to the cabinet 3, if the filter 7 is attached to the cabinet 3, a foreign object such as a human finger does not directly hit the temperature detector 25. However, when the filter 7 is removed, the temperature detector 25 is exposed to the outside, and foreign matter may hit the temperature detector 25, and the temperature detector 25 may be displaced.

Therefore, as shown in FIG. 3, the filter guide 13 is provided with a positioning portion 78 for preventing the temperature detector 25 from being displaced. The positioning portion 78 is formed in a rectangular frame shape and surrounds the upper, lower, left and right sides of the holder 27. As a result, only the front surface of the holder 27 is exposed to the outside, and foreign matter is less likely to hit. Even if a foreign object hits the front surface of the holder 27, the holder 27 does not move backward because of the buffer body 77. Moreover, even if the wind pressure of the sucked air is received, the wind does not hit the upper, lower, left and right sides of the holder 27, and the holder 27 does not vibrate. Therefore, the temperature detector 25 can be stably held without being displaced, and the temperature of the air sucked from the room can always be detected in the same state. The temperature detector 25 can detect the room temperature which changes every moment in the same state by the positioning part 78 and the buffer body 77, and can maintain favorable detection sensitivity.

In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. The temperature detector may be rotated around a rotation axis parallel to the front-rear direction. The temperature detector rotates upward or downward from the detection posture. A storage space is formed in the electrical box. When the temperature detector is stored in the storage space, the temperature detector is in the storage posture, and the temperature detector is hidden in the electrical box. Moreover, you may provide a rotating shaft in an electrical equipment box. The holder of the temperature detector is fitted on the rotating shaft.

¡A temperature detector is slidable with respect to the electrical box. As the temperature detector slides in the left-right direction, the temperature detector is taken in and out of the storage space formed in the electrical box, and the detection posture and the storage posture of the temperature detector are switched.

In the above embodiment, the temperature detector is integrally provided in the electrical box. However, the temperature detector is not limited thereto, and the temperature detector may be provided in a built-in unit that is detachably incorporated in the cabinet. For example, a temperature detector is provided in a drain pan unit disposed below the heat exchanger so that the posture can be switched. Instead of the temperature detector, a humidity detector may be provided in the electrical box or the drain pan unit so that the posture can be switched. Or you may provide an ion concentration detector in the ion generating unit arrange | positioned at a blower outlet so that attitude | position switching is possible. These detectors are installed at positions where they can come into contact with an object to be detected such as room air, ions, heat exchanger temperature (refrigerant temperature) related to control of air conditioning operation.
