Description

The present invention relates to an air conditioner, and particularly to an outdoor unit.

A conventional outdoor unit of an air conditioner will be described with reference to FIG. In FIG. 7, a wind direction changing device 122 is provided on the wind discharge surface side of the outdoor unit 101 so as to surround the wind direction chamber 121, and the wind direction changing device 122 that directs the wind from the front to the top is also used as the mounting screw 113 of the outdoor unit 101. ing. By installing the air direction changing device 122 as far as the depth dimension L of the outdoor unit 101, a space area S for sufficiently storing the discharge air is secured, the pressure loss is reduced, and the air is smoothly discharged in the upper rectangular shape. By discharging from the outlet 123, noise reduction during blowing and unpleasant wind hitting the human body can be avoided. (For example, see Patent Document 1)
Japanese Patent Laid-Open No. 11-237083

  However, in the above-described conventional configuration, the front panel 102A is an integral type. Therefore, in the case of the outdoor unit 101 in which the maintenance of the electrical block unit (not shown) is performed from the front panel 102A side, the wind direction chamber 121 is temporarily set. If it was not removed, there was a problem that maintenance work of the electrical block unit could not be performed.

  The present invention solves such conventional problems, and provides an air conditioner that is easy to perform maintenance work, suppresses the air volume loss of the discharge air and the accompanying capacity loss, and can easily change the direction of the discharge air. It is intended to provide.

  In order to solve the above-mentioned conventional problems, the outdoor unit of the air conditioner of the present invention has a front panel having a discharge port for blowing air from the blower fan, and is used for maintenance of the electrical block unit and detachable from the front side. The front panel is provided with a wind direction changing device that changes the direction of the air blown from the outlet, and the service panel can be removed without removing the wind direction changing device during maintenance of the electrical block section. The workability of maintenance can be improved because only the work can be performed.

  The air conditioner of the present invention is easy to perform maintenance work, suppresses the air volume loss of the discharge air from the outdoor unit and the accompanying performance loss, and can easily change the direction of the discharge air.

  1st invention consists of the indoor unit distribute | arranged indoors, the said indoor unit via the refrigerant | coolant piping, and the outdoor unit which incorporated the ventilation fan and the electrical equipment block part, The said outdoor unit is from the said ventilation fan. A front panel having a discharge port for blowing air, and a service panel for maintenance of the electrical block unit and detachable from the front side, the wind direction changing the direction of the wind blown from the discharge port on the front panel Since the change device is provided and the maintenance can be performed only by detaching the service panel without removing the wind direction changing device at the time of maintenance of the electrical block unit, it is possible to improve maintenance workability.

  In particular, the second aspect of the present invention uses a mixed flow fan as the blower fan of the first aspect of the invention, and the wind direction changing device has a facing surface portion that faces the discharge port, an opening that blows air, and a width from the front panel to the facing surface portion. Has a side portion that gradually expands, and a space for storing discharge air is secured in a portion where the width increases toward the facing surface portion, so that it is possible to suppress an air volume loss and a performance loss associated therewith.

  According to a third aspect of the present invention, in particular, the wind direction changing device according to the first or second aspect of the present invention connects the opposed surface portion facing the discharge port, the opening for blowing out the wind, the front panel and the opposed surface portion, and opens the wind. And the opening is formed with a width larger than the discharge port in the surface direction of the discharge port, and the discharge air blown obliquely to the facing surface portion is the width of the side portion. Flows along the enlarged portion and is blown out from the opening at a wide angle, so that the wind can be discharged smoothly.

  The fourth aspect of the invention is particularly formed so that the wind direction changing device according to any one of the first to third aspects of the invention can be attached and detached and the discharge direction of the discharge air can be changed according to the mounting direction to the front panel. Therefore, it is possible to easily change the discharge direction of the discharge air to the left and right simply by changing the mounting direction of the wind direction change device, and if the air direction is changed in a space with many closed parts and less opening, the problem of short circuit will be solved. it can.

  According to a fifth aspect of the invention, in particular, the wind direction changing device according to any one of the first to fourth aspects of the invention includes a first wind direction changing unit that restricts at least blowing of air to the lower side of the outdoor unit, and the first wind direction changing. It has a second wind direction changing part that is detachable from the part and regulates the blowing direction. By simply selecting the shape of the second wind direction changing part, various blowing directions can be realized and the parts can be miniaturized. Therefore, workability at the time of installation can be further improved.

  In the sixth aspect of the invention, in particular, the wind direction changing device according to any one of the first to fifth aspects of the invention includes at least a facing surface portion facing the discharge port and a side surface portion that regulates blowing of air to the lower side of the outdoor unit. Since the wind is discharged not only from the upper side but also from the upper side which is not restricted by the blowing, the discharged air can be dispersed and discharged smoothly.

  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)
Hereinafter, the air conditioner in the 1st Embodiment of this invention is demonstrated using FIG.

  In the figure, reference numeral 1 denotes an outdoor unit connected to an indoor unit (not shown) disposed indoors through a refrigerant pipe (not shown), and has a blower fan 1a inside, and the blowout of the blower fan 1a The front panel 3 which has the discharge outlet 2 which blows off the ventilation from the said ventilation fan 1a is provided in the direction side. Reference numeral 5 denotes a service panel that is attached / detached at the time of maintenance of an electrical block unit (not shown) built in the indoor unit 1 and is provided separately from the front panel 3. The front panel 3 is provided with a wind direction changing device 4 that changes the direction of the air blown forward from the discharge port 2.

  According to the above configuration, when the maintenance of the electrical block part is performed, it is possible to remove only the service panel 5 and thus the trouble of removing the front panel 3 and the wind direction changing device 4 as in the conventional case is not required. Workability is remarkably improved.

(Embodiment 2)
Next, a second embodiment of the present invention will be described with reference to FIG. Note that the same portions as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
