Abstract

PURPOSE:To enable the direction of a heat exchanger to be changed on the front side without changing on the lateral side, by a construction wherein the spacing between both frame side plates is set to be larger than the width of a heat exchanger and smaller than the width of a dew pan, and a pressing means for closing a notched part is detachably fitted to the frame side plate opposed to a higher end part of the pan. CONSTITUTION:For example, when changing from a left-side piping to a right- side piping, a front panel 25 is opened, the pressing means 45 fixed to the frame side plate 32 is detached, then a screw 44 provided at a fixing plate 43 for the heat exchanger 30 is removed, and the heat exchanger 30 is displaced leftward by lifting it. In this case, an end part 38 of the dew pan is protruded largely from the plate 32 by sliding the notched part 40 of the plate 32, thereby inclining the heat exchanger 30, and as a result of the inclination, an end part 37 is disengaged from a notched part 39 of the right frame side plate 31. After this, by drawing the right of the heat exchanger to the front side, the end part 38 of the dew pan is disengaged from the left notched part 40.

A heat insulating material 7 is pasted on the inside. 8 is a heat exchanger, frame side plate (not shown)
A solid wax plate 9 for fixing the heat exchanger fixed to the heat exchanger 8
The receiving plate 10 is fixed to both ends of the side plate, extends in the longitudinal direction, and is provided with a hole 10a for condensed water to fall. Reference numeral 11 denotes a dew pan slanted toward the drain outlet, which is placed on the motor plate 11a, has a heat insulating material 12 attached thereto, and is located below the heat exchanger 8. 13 is a fan, 14 is a fan casing, 1
6 is an air filter installed at the bottom of the main body, which serves as a suction port. 16 is a base. Reference numeral 17 denotes a shielding plate, and a heat insulating material 18 is pasted above the heat exchanger 8 in order to block ventilation and to support the upper part of the heat exchanger 8.

Conventionally, the configuration was as described above. For example, when cooling water is passed through the heat exchanger 8 and the fan 13 is operated, air flows from the lower suction port through the air filter 16 and flows into the heat exchanger 8. The air passes through the air, becomes cold air, and is blown out from the blow-off grille 6.

The condensed water that has condensed on the heat exchanger 8 drips downward, drips into the dew pan 11 through the plurality of holes 10a of the receiving plate 1o, and is drained from a drain port provided on the side.

The piping connected to the heat exchanger 8 can be either the right piping or the left piping, depending on the installation conditions of the air conditioner. For example, the left piping can be connected to the right piping. When switching to connecting to piping, open the front panel 6, remove the screws 9a of the fixing plate 9, remove the receiving plate 10, and insert the heat exchanger 8 held by penetrating the frame side plate. Pull it out laterally, reverse the direction, change the direction, and switch to the left piping.

That is, the windward surface becomes the leeward surface, and the leeward surface becomes the windward surface and are connected.

Problems to be Solved by the Invention In such a conventional configuration, if the piping direction had to be changed during installation on site, the heat exchanger 8 could be pulled out laterally, reversed, and then redirected. In order to change the heat exchanger 8, as mentioned above, the screws 9a of the fixing plate 9 must be removed, the receiving plate 1o must be removed, and the side plate of the heat exchanger 8 must be removed from the state where it is held by penetrating the frame side plate. This involves work such as pulling it out laterally, and since it is pulled out laterally, the plate fins of the heat exchanger 8 may fall down.
In addition, there were problems such as damage.

The present invention solves these problems.

To construct a dew pan and a receiving plate integrally, and to change the direction of a heat exchanger from the front without changing the direction from the side.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a main body in which a heat exchanger is installed, a dew pan provided at the bottom of the heat exchanger so as to be inclined to one side, and a dew pan provided at the bottom of the heat exchanger, a receiving plate removably provided between the receiving plate and the front panel of the main body so as to partition an area above and below the dew receiving plate; and a receiving plate provided on both sides of the heat exchanger, each at a lower end of the dew receiving plate. and a frame side plate having a notch into which the dew pan is inserted, the interval between the frame side plates being larger than the width of the heat exchanger and smaller than the width of the dew pan, and a higher end of the dew pan. A presser for closing the notch is removably provided on the side plate of the frame facing the cutout.

Function With the above configuration, when changing the left and right side of the heat exchanger and condensation pan piping, remove the front panel, remove the holding tool and the catch plate,
After shifting the heat exchanger to the left and right and pulling it out forward from the frame side plates, turn it upside down and install it again between the frame side plates, attach the presser and catch plate to the dew pan, and attach the front panel. Become.

EXAMPLE Hereinafter, an example according to the present invention will be explained with reference to FIGS. 1 to 6. 20 is the main body of the air conditioner, and this main body 2o has a rear top plate 21, a front top plate 22, an air outlet 23, and an operation lid 24 on the top side, and a front panel 25 that can be opened and closed freely on the front side. It is comprised of an exterior side plate 26 and a base 27 provided at the bottom. In Figures 2 to 4, 3o is a heat exchanger for passing cold and hot water, and this heat exchanger 30 is now capable of right-hand piping, and has frame side plates installed at both ends. A socket 33 for connecting piping is fixed to the frame side plate 31 at 31 and 32. The frame side plate 32 is still provided with a socket hole 34 for left piping. 35 is a semi-circular dew tray that is inclined so that condensed water flows only to one side below the heat exchanger 30. A heat insulating material 3e is pasted on the outside, and both ends 37.
38 is attached to the frame side plate 31.32 at the end 37 and at the end 3.
It is inserted and held in notches 39 and 40 that are large enough to allow insertion even in the case of 8.

A receiving plate 43 is a fixing plate for fixing the heat exchanger 30, and this fixing plate 43 is
It is fixed to the frame side plate 31, 32 by welding, and screws 4
4 fixes the heat exchanger 3o from the front side. 45 is the end 3 of the condensation tray 36 on the opposite side of the pipe to be connected.
8 and is fixed to the frame side plate 32 with a presser fitting attached to press the end portion 38. 46
is the motor plate, 47 is the fan, 48 is the fan casing,
49 is an air filter provided at the suction port 28.

Note that by providing the dew pan 35 at an angle, the end portion 37 becomes the drain port 6o. The flanges 35a and 3 allow the receiving plate 41 to be attached to either the left or right side of the pipe.
5b is provided. In Fig. 4, 61 is a collection plate;
The condensed water dripping from the drain port 6o is received and drained through the hose 52.

In the above configuration, during cooling, air flowing in from the suction port 28 passes through the air filter 49 and the heat exchanger 3o, where it becomes cold air and is blown out from the blow-off grille 23. In this heat exchanger 30, the condensed water drips into the semicircular dew pan 35 and is drained from the drain port 60 on the right side inclined downward.

Next, if you want to change the left piping from the right piping, open the front panel 26, remove the holding metal fittings 46 fixed to the frame side plate 32, and then remove the fixing plate 46 of the heat exchanger 30.
3. Remove the screws 44, hold the heat exchanger 30,
Move it to the left.

At this time, the notch 40 (indicated by the dotted line in FIG. 2) of the frame side plate 32 is slid, and the end 38 of the dew pan protrudes beyond the frame side plate 32, causing the heat exchanger 3o to be biased. Due to this deviation, the right frame side plate 3
The end portion 37 is removed from the notch portion 39 of No. 1. When it comes off, remove the end 38 of the dew pan from the notch 4o on the left side by pulling the right side forward.

Next, in order to establish the left piping, the receiving plate 41 is removed, the direction of the heat exchanger 3o is changed so that the back and front surfaces are changed, and the receiving plate 41 is fixed to the flange ssb. Then, with the heat exchanger 30 and the dew pan 36 integrated, insert the end 38 obliquely from the front into the notch 39 of the frame side plate 31, and when it is inserted to the longest extent, on the left side. Align the notch 40 of the frame side plate 32 with the end 37 and insert. When this insertion is completed, the heat exchanger 30 is shifted to the left side, and the end portion 38 is held down by attaching a holding metal fitting 45 to the right frame side plate 31. At this time, in the symmetrically provided socket holes 34,
A socket 33 is fitted.

Note that after changing the direction of the heat exchanger 30 and the dew pan 36, the socket hole and the semicircular notch 3 are removed.
9.40 gaps should be closed with heat insulating material, seal tape, etc. to prevent air leakage.

As a result, the heat exchanger 30 and the dew pan 36 can be constructed integrally, and when changing the piping direction, the heat exchanger 30 integrated with the dew pan 36 can be constructed from the front. This makes it possible to change the direction, and there is no possibility of damaging the plate fins of the heat exchanger 30.

Effects of the Invention As described above, according to the air conditioner of the present invention, when changing the left and right piping, the direction of the heat exchanger can also be changed from the front after opening the front panel. Since the heat exchanger and the dew pan are integrated, there is no need to change the orientation of the heat exchanger and the dew pan individually as in the past, and the orientation can be changed at the same time as the heat exchanger. This has the advantage of eliminating collapse and damage, and simplifying piping modification work.
