Description

Description: TECHNICAL FIELD The present invention relates to an air conditioner using a heat pump, and particularly to improvement of a wind guide panel of an outdoor side exchanger section and its mounting structure.

[Conventional technology]

FIG. 3 is a perspective view of an outdoor heat exchanger portion of a conventional air conditioner. In the figure, reference numerals 1a and 1b denote front and rear heat exchangers which are arranged in a V shape so that the lower sides thereof are close to each other and through which a refrigerant flows.
2 is a support member for supporting these heat exchangers 1a and 1b from below, 3a
Reference numerals 3 and 3b denote left and right side panels that sandwich and support the heat exchangers 1a and 1b from both sides and also serve as exterior panels. 4a and 4b are front and rear panels mounted across the upper portions of both side panels 3a and 3b, and 5 is a heat exchanger 1.
A blower which is arranged above a and 1b and which ventilates the outside air to perform heat exchange, 6 is above the both side panels 3a and 3b (top part)
Is a wind guide panel that also serves as an upper panel, and a bell mouth portion 6a protruding in a cylindrical shape is formed in the central portion of the wind guide panel to surround the outer periphery of the blade 5a of the blower 5 with a gap. And guide the exhaust air.

FIG. 4 shows an exploded perspective view of the wind guide panel 6 and the front and rear panels 4a and 4b. Reference numerals 7a and 7b denote front and rear beams attached to the upper portions of the heat exchangers 1a and 1b, and both ends of a frame body 8 to which a blower 5 is attached are screwed to the upper surfaces of these beams.

The front and rear panels 4a, 4b are attached to the front and rear bent edges of the side panels 3a, 3b by screws 9 at their lower ends. The wind guide panel 6 has four edges bent downward, and is covered so as to cover the upper outer peripheries of the side panels 3a, 3b and the front and rear panels 4a, 4b, and the upper bent edges of the side panels 3a, 3b. It is attached to the section with four screws 10.

[Problems to be Solved by the Invention]

In the conventional air conditioner as described above, above the heat exchangers 1a, 1b, the wind guide panel 6 of the blower 5 and the front and rear panels 4a, 4b.
Since b and the b are separately attached to the side panels 3a and 3b, respectively, there is a problem that the number of parts is increased and the assembling work is troublesome. Further, since the blower 5 and the wind guide panel 6 are attached to the beams 7a and 7b and the side panels 3a and 3b, which are separate attachment points, the blades 5 of the blower 5 are attached.
The center position between a and the bell mouth portion 6a of the wind guide panel 6 is easily displaced, which may deteriorate the characteristics of the blower or cause the blade 5a to contact the bell mouth portion 6a. In the worst case, the blade may not rotate. There was a problem.

The present invention has been made to solve such a problem, reduces the number of parts in the enclosure above the outdoor heat exchanger unit, simplifies the assembly work, and reduces the fan blades and the enclosed panel. The purpose of the present invention is to obtain an air conditioner that can be easily assembled concentrically with the bellmouth.

[Means for Solving the Problems]

The air conditioner according to the present invention has the front and rear portions of the wind guide panel of the blower above the outdoor heat exchanger section bent downward,
The front and rear panels are integrally formed, and the air guide panels are mounted and guided by attaching the mounting edges protruding from the lower ends of the front and rear panels to the beams above the heat exchangers. The side edges bent inward are formed on both sides of the wind panel, and the side edges are fitted to the upper portion of the side panel.

[Action]

In the present invention, the wind guide panel is integrally formed with the front and rear panel parts, and the number of parts is reduced by assembling this wind guide panel to each beam at the mounting edges of the front and rear panel parts. Workability is improved. In addition, the wind guide panel is attached to the beam to which the blower is attached, and the wind guide panel is configured to fit on the side panel, and the center position of the bell mouth of the blower vane and the wind guide panel is concentric. Assembled.

〔Example〕

FIG. 1 is a perspective view of an outdoor heat exchanger part showing an embodiment of the air conditioner according to the present invention, and includes 1a, 1b, 2, 3a, 3b, 5, 5a.
Is the same as the conventional one, and the explanation is omitted. Reference numeral 11 denotes both side panels, a wind guide panel which is attached to cover the upper side of 3a, 3b, and also serves as an upper panel, and a bell mouth portion 11a protruding in a cylindrical shape is formed, and the outer periphery of the blade 5a of the blower 5 is formed. Is surrounded by a gap to guide the exhaust air. The wind guide panel 11 has front and rear parts extended and bent downward, and front and rear panel parts 11b and 11c are integrally formed.
The side panels 3a and 3b are fitted so as to cover the outer peripheries of the upper portions.

Next, details of the exploded perspective view of the air guide panel 11 are shown in FIG. The lower ends of the front and rear panel portions 11b and 11c of the wind guide panel 11 are slightly inwardly bent, and then further downwardly bent to attach to the respective beams 7a and 7b from the outside at the mounting edges 11d, 11e
Are formed. Further, both side edge portions of the board 11j of the wind guide panel 11 and both side edge portions of the front and rear panels 11b, 11c are bent inward (downward, frontward, rearward) to form side edge portions.
11f, 11g, and 11h are integrally formed.

The wind guide panel 11 formed in this way is attached to both side panels 3a, 3
Placed on b, front and rear panel parts 11b, 11c and side edge parts 11f, 11g, 11
While being fitted to the outer peripheries of the upper parts of both side panels 3a, 3b with h, the mounting edges 11d, 11e are brought into contact with the corresponding beams 7a, 7b from the outside and are mounted by the screws 9. Thus, it is assembled as shown in FIG.

In this way, the mounting frame 8 of the blower 5 and the wind guide panel 11
Are attached to the beams 7a and 7b together, and therefore, the blades of the blower 5 can be formed by machining the mounting screw holes 11i and 7c of the wind guide panel 11 and the beams 7a and 7b at the precise relational positions. The center positions of 5a and the bell mouth portion 11a can be easily assembled concentrically.

〔The invention's effect〕

As described above, according to the present invention, the front and rear portions of the air guide panel above the outdoor heat exchanger portion are bent downward, the front and rear panel portions are integrally formed, and the blower is attached. Since the wind guide panel is attached to the rear beam at the attachment edges of the lower portions of the front and rear panels, the number of components is reduced, the assembling work is simplified, and the productivity is improved. Further, the central positions of the blades of the blower and the bell mouth portion of the wind guide panel can be easily assembled concentrically.
