Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fixing device for an outdoor unit for an air conditioner, which fixes the outdoor unit for an air conditioner to a foundation on which anchor bolts are installed.

Conventionally, when fixing an outdoor unit for an air conditioner on a foundation with anchor bolts installed, fixed mounting plates having mounting holes through which the anchor bolts are inserted are welded to several places on the side of the bottom frame. Ok,
The outdoor unit was mounted on the foundation by inserting an anchor bolt into the mounting hole of the fixed mounting plate and screwing the nut.

However, in the conventional type mentioned above, the fixed mounting plate is welded to the bottom frame, so for quality control reasons, the welded part must be treated with anti-corrosion treatment, which is expensive, and it is not fixed to the side of the bottom frame. There was a problem in that the fixed mounting plate came into contact with other structures and deformed when the outdoor unit was being transported.

Therefore, in order to solve the above problem, as shown in Fig. 4, a horizontally long rectangular through hole b is provided in the side surface of the bottom frame a of the outdoor unit, while a fixed mounting plate c is provided with a mounting hole d through which an anchor bolt is inserted. The horizontal fixing part e has an L-shaped cross section, and the locking part f rises from the edge of the horizontal fixing part e along the side of the fuselage, and the tip of the locking part f is locked in the through hole b. Stop f
Horizontal fixing part e with the tip locked in through hole b
The outdoor unit is mounted on the foundation g by inserting the anchor bolt into the mounting hole d and screwing the nut.This eliminates the need for welding and rust prevention treatment, and also allows the outdoor unit to be fixed on the mounting plate when transported. It has been proposed to remove c to prevent its deformation (see Japanese Utility Model Publication No. 74288/1988).

However, in the above proposal, since the through hole b must be provided on the side surface of the bottom frame a, cost reduction cannot be achieved due to the processing, and the end of the locking part f must be locked in the through hole b by both Due to the play between the two, there was a problem in that there was insufficient force to restrain the bottom frame a in the lateral direction of the through hole b relative to the foundation g, making it difficult to securely fix the outdoor unit on the foundation g without shifting.

The present invention has been made in view of this point, and is formed by bending a substrate parallel to the fins at a right angle from the outer end of the substrate, close to the rising portion provided at the side end of the bottom frame. In an outdoor unit in which a heat exchanger made of a cross-fin coil with a tube plate made of bent pieces is fixedly arranged, a fixed mounting plate can be attached to the rising part without welding or processing to reduce costs. In addition to preventing deformation of the fixed mounting plate during transportation of the outdoor unit, the outdoor unit is mounted on the foundation by using the bent pieces of the tube plate of the heat exchanger to hold the tube plate between the fixed mounting plates. The purpose is to securely fix it without shifting in the lateral direction.

In order to achieve this objective, the configuration of the present invention is to fix the outdoor unit for an air conditioner in such a way that the outdoor unit for the air conditioner is fixed via a fixed mounting plate on a foundation in which anchor bolts are installed. It is a device,
The outdoor unit has a heat exchanger made of a cross-fin coil having a tube plate made of a board parallel to the fins and a bent piece formed by bending the board at right angles from the outer end of the board. The fixed mounting plate has an L-shaped cross section and has a mounting hole through which the anchor bolt is inserted, and a nut is screwed onto the anchor bolt. a horizontal fixing part that is fixed by fitting together; a bifurcated clamping part consisting of a pair of clamping pieces that rises from the edge of the horizontal fixing part so as to sandwich the bent piece of the tube sheet; It consists of a locking part provided at the tip of each clamping piece and locking the rising part of the bottom frame. As a result, with the tube plate of the heat exchanger being clamped by the clamping part and the floating of the rising part of the bottom frame being restrained by the locking part,
The fixed mounting plate is attached to the bottom frame and fixed to the foundation via the horizontal fixing part, so that the outdoor unit is fixed without shifting in the vertical and lateral directions.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Figures 1 to 3 show an embodiment in which the present invention is applied when a three-way suction type outdoor unit for an air conditioner is fixed on a foundation formed by laying concrete. and the outdoor unit A
is a rectangular bottom frame 2 placed on a foundation 1
and a heat exchanger 3 made of a cross-fin coil disposed on the bottom frame 2 in close proximity to the rising portion 8 provided at the side end of the bottom frame 2 so as to face three sides of the outdoor unit body; A ceiling frame 4 that is attached to the upper surface of the heat exchanger 3 and has an air outlet 4a in the center, and a blower fan (not shown) that is disposed on the bottom frame 2 opposite to the air outlet 4a, The outside air around the heat exchanger 3 is sucked in from three sides by a fan, heat exchanged with the three sides of the heat exchanger 3, and then the air is sent to the air outlet 4.
The air is blown out from a.

The heat exchanger 3 has tube sheets 5 . . . erected corresponding to approximately four corners of the bottom frame 2, and tube sheets 5 . The refrigerant pipe 6 is composed of a refrigerant pipe 6 that is piped through the refrigerant pipe 6, and a number of fins 7 that are fitted into the refrigerant pipe 6. It is connected to a pipe to form a series of refrigerant circuits, and is configured to exchange heat between the refrigerant introduced from the indoor unit and the outside air. The tube plate 5 is composed of a substrate 5a parallel to the fins 7, and bent pieces 5b and 5c formed by bending the outer and inner ends of the substrate 5a at right angles in the same direction, respectively, and has a U-shaped cross section. It is formed in the shape of Note that the bent piece 5c on the inner end side is not necessarily required.

Further, the bottom frame 2 has a side end bent upward to form a rising portion 8, and a tube plate 5 of the heat exchanger 3 is inserted into the rising portion 8 on the side surface of each tube plate 5. The heat exchanger 3 is fixed to the rising portion of the bottom frame 2 by screwing together the bolts 9 .

On the other hand, 10 is a fixed mounting plate for fixing the outdoor unit A onto the foundation 1 via anchor bolts 11 installed in the foundation 1, and the fixed mounting plate 1
0 is formed into an L-shaped cross section, and includes a rectangular flat horizontal fixing part 12 having a mounting hole 12a corresponding to the anchor bolt 11 in the center, and the tube plate 5 from the edge of the horizontal fixing part 12. A bifurcated clamping part 13 is formed by a pair of clamping pieces 13a, 13a that stand up to sandwich the bent piece 5b, and the tips of the clamping parts 13a, 13a of the clamping part 13 are bent into a hook shape. The locking portions 14 are locked to the rising portions 8 on both sides of the tube plate 5 in the bottom frame 2, and the clamping pieces 13a, 13a of the clamping portions 13 are provided.
The bent piece 5b on the outer end side of the tube sheet 5 is held between the opposite side ends of the tube plate 5, and the anchor bolt 11 is inserted into the mounting hole 12a of the horizontal fixing part 12 and a nut is inserted into the anchor bolt 11. 15 is screwed together, the outdoor unit A is fixed to the foundation via the fixed mounting plate 10.

Therefore, since the fixed mounting plate 10 locks the bottom frame 2 at its locking portion 14, there is no welded portion and there is no need for anti-corrosion treatment, thereby reducing costs accordingly. Furthermore, since the fixed mounting plate 10 is a removable member independent of the bottom frame 2, when the outdoor unit A is transported, the fixed mounting plate 10 can come into contact with other structures by removing it from the bottom frame 2. and deformation can be prevented. Furthermore, since the fixed mounting plate 10 is directly engaged with the rising portion 8 of the bottom frame 2, there is no need to newly form a through hole in the bottom frame 2, which can further reduce costs.

In addition, since the tube plate 5 fixed to the bottom frame 2 is clamped by the clamping part 13 of the fixed mounting plate 10, the existing tube plate 5 can be used for outdoor operation without any processing on the outdoor unit A side. The machine A can be securely fixed on the foundation 1 without shifting in the lateral direction.

As explained above, according to the present invention, a fixing device for an outdoor unit for an air conditioner is configured to fix the outdoor unit for an air conditioner to a foundation on which anchor bolts are installed via a fixed mounting plate. The outdoor unit includes a heat exchanger made of a cross-fin coil having a tube plate made of a board parallel to the fins and a bent piece formed by bending the board at a right angle from an outer end of the board. The fixed mounting plate is disposed close to a rising portion provided at the side end of the bottom frame, and the fixed mounting plate has an L-shaped cross section and has a mounting hole through which the anchor bolt is inserted. a horizontal fixing part fixed by screwing a nut to the horizontal fixing part; a bifurcated clamping part made of a pair of clamping pieces rising from the edge of the horizontal fixing part so as to sandwich the bent piece of the tube sheet; Since it is composed of a locking part provided at the tip of each gripping piece of the gripping part and locking the rising part of the bottom frame, the outdoor unit can be mounted on the foundation in the vertical direction with a simple structure using a tube plate. In addition, the fixing plate can be reliably fixed without shifting in the lateral direction, and the fixing plate can be removably attached to the bottom frame without welding or processing, reducing costs. This has an excellent practical effect of preventing deformation.
