Description

Electric heater and orifice mounting device of air conditioner

The present invention relates to an air conditioner, and more particularly, to an electric heater and an orifice mounting apparatus of an air conditioner, in which an electric heater is installed in front of an orifice in order to serve as heating.

In general, an air conditioner is called an air conditioner. The air conditioner is a device that lowers a room temperature to a predetermined temperature by inhaling hot air in a room and cooling and discharging it by a heat exchange action by a heat exchanger.

The air conditioner is classified into an upper type type installed on the floor of the room, a wall type attached to the wall of the room, and a window type attached to the window.

At this time, the indoor unit and the outdoor unit are separated from each other, but the indoor unit and the outdoor unit are integrated.

Referring to Figure 1 attached to the structure of a conventional general air conditioner as follows.

1 is a perspective view showing a general air conditioner and FIG. 2 is a longitudinal cross-sectional view of an air conditioner in which a conventional apparatus is installed, and a plurality of discharge holes are formed at both sides and the upper part so as to be located at an outdoor side when installed in a window (not shown). A main body 1 having a 1a formed thereon, a front grill 4 detachably coupled to the front surface of the main body, having a suction grill 2 and a discharge grill 3, and a blower fan installed at the rear of the front grill. An indoor heat exchanger 6 for converting hot air sucked by (5) into cold air by a heat exchange action, and a scroll for guiding cold air passing through the indoor heat exchanger toward the discharge grill 3 (7). ), An outdoor heat exchanger (9) installed on the base (8) so as to be located on the outdoor side in the main body, and a heat exchanger (9) which is installed on one side of the front grill to exchange heat with external air, and a control unit for setting an operation mode. 10, etc. It is.

If the user sets the cooling mode by operating the switch of the control unit 10 to cool the room in a state where the air conditioner is configured as described above, the air conditioner is driven according to the set control signal, thereby cooling the room. .

That is, when the compressor is driven according to the selected control signal to form a refrigeration cycle, the temperature of the indoor heat exchanger 6 drops.

In this state, when the blower fan 5 located in the indoor side is rotated by the driving of the motor 11 to suck the hot air in the room through the suction grill 2, the hot air in the room takes the indoor heat exchanger 6. As it passes through the coolant flowing through the coolant pipe, the coolant is cooled and then discharged through the scroll 7 to the discharge grill 3 so that the temperature of the room is gradually lowered.

Through the operation as described above, the heat exchanged with the air introduced while passing through the refrigerant pipe of the indoor heat exchanger 6 and the refrigerant heated up are re-introduced into the compressor through the outdoor heat exchanger 9 through the refrigerant pipe. It is compressed to high temperature and high pressure and then moved to the indoor side heat exchanger 6 to perform the heat exchange as described above, thereby enabling continuous cooling of the room.

Since the air conditioner is only used for a limited time in the summer when the outside air temperature is high, it is not efficient, and recently, an air conditioner that can be used as a heating device in the winter has been developed and used.

An air conditioner that also serves as heating is installed such that a heater, which is a heat source, is positioned in front of the orifice 12.

FIG. 2 is a longitudinal sectional view of an air conditioner in which a conventional apparatus is installed, and FIG. 5 is a front view of a state in which a heater is mounted on an orifice in a conventional apparatus. First, the mounting structure of the orifice 12 will be described.

A bent piece 13 is formed at an upper portion of the orifice 12 which guides the suction air to the blowing fan 5 side, and the bent piece 13a is fitted to the protrusion 7a of the scroll 7 at the bent piece. The fastening hole 13b for fixing the heater cover 15 using the screw 14 is formed on the opposite side of the bent piece.

A bent piece 12a fitted to the support bracket 16 fixed to the base 8 is formed under the orifice 12.

Therefore, the bending piece 12a formed in the lower portion of the orifice 12 is sandwiched between the base 8 and the support bracket 16, and then the fastening hole 13a of the bending piece 13 formed in the upper portion is formed in the scroll 7. The orifice 12 is attached to the set because the screw 14 is fastened to the fastening hole 13b.

On the other hand, the mounting structure of the heater detachably installed on one side of the orifice 12 for heating is as follows.

The coil 18 that generates heat when the power is applied to the bracket 17, which is a press product, is fixed to be arranged in a zigzag shape, and an insertion hole 19 is formed at the four corners of the bracket, and an air suction hole 12b is formed. The formed orifice 12 has a fastening hole 12c to which the screw 20 is fastened to correspond to the insertion hole 19.

Therefore, the assembly of the heater is completed since the bracket 17 having the coil 18 fixed thereto is connected to the orifice 12 and then the screw 20 is fastened through the fastening hole 12c.

As such, the air conditioner equipped with the heater may be deteriorated due to deformation due to repeated thermal expansion of the coil 18 due to long-term use in winter.

However, such a conventional device uses a tool to separate the screw 20 by narrowing the distance between the indoor heat exchanger 6 and the orifice 12 even when the heater cover 15 is removed from the set to replace the heater. And since it cannot be fastened, the heater orifice 12 must be completely disassembled from the set, so the replacement work of the heater was very troublesome.

In addition, the bracket 17 to which the coil 18 is fixed is formed as a plate-shaped press, and flow resistance when external air flows into the orifice air suction hole 12b by suction force caused by rotation of the blowing fan 5. Since the action of water had to increase the number of revolutions (RPM) of the motor (11), thereby increasing the power consumption, there was also a problem that a lot of noise during operation.

The present invention has been devised to solve such a problem in the prior art, and the structure is improved to improve the structure by the support method according to the assembly of the parts, not the fastening method of the bracket by screws, thereby improving the maintenance work of the heater. The purpose is to make it easier.

Another object of the present invention is to change the shape of the bracket to which the coil is fixed to minimize the flow resistance of the intake air flowing into the body.

According to a form of the present invention for achieving the above object, the insertion hole is formed on the upper, lower bent piece of one side, the orifice screwed to the barrier, the insertion piece and the upper part inserted in the insertion hole formed on the lower bent piece An engaging piece is formed to be inserted into the insertion hole formed on the bent piece, the air is composed of a heater cover having a bracket on which a coil that generates heat upon application of power is fixed, and an embossing portion connected to the upper surface of the engaging piece to support the bracket. An electric heater and orifice mounting device of the conditioner is provided.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 6 to 9 as an embodiment.

Figure 6 is a longitudinal cross-sectional view of the air conditioner equipped with the device of the present invention and Figure 9 is a front view of the orifice and the heater is mounted in the present invention, the present invention is one of the orifice 12 is screwed to the barrier 21 Bending pieces 22 and 23 are formed at the upper and lower sides of the side surfaces, respectively, and insertion holes 22a and 23a are formed at the upper and lower bending pieces.

The orifice 12 is screwed to the barrier 21 is formed short so that the lower end is spaced apart from the base (8).

This is to reduce the noise generated by the vibration generated during operation.

And the lower portion of the bracket 24 that is detachably mounted to one side of the orifice 12 is formed with an insertion piece 25 to be fitted in the insertion hole 23a formed on the lower bending piece 23 and the upper portion The engaging piece 26 is inserted into the insertion hole 22a formed on the bent piece 22, and the upper and lower bent pieces 22 and 23 formed in the orifice 12 and the bracket 24 are formed. It is preferable to set the insertion piece 25 and the locking piece 26 formed in the two) as shown in FIG.

This is to enable the heater to be mounted in the orifice 12 in a stable state.

The bracket 24 has a rod shape.

This is to minimize the flow path resistance generated when the air in the room enters the orifice air suction hole 12b formed in the orifice 12 by the suction force due to the rotation of the blowing fan 5.

On the bracket 24, a coil 18, which generates heat in accordance with the application of a power source, is fixed like a conventional air conditioner.

The lower surface of the heater cover 15 for closing the upper side of the heater mounted on the orifice 12 is formed with an embossing portion 15a connected to the upper surface of the engaging piece to support the bracket.

Referring to the operation of the present invention configured as described above are as follows.

First, when the orifice 12 having the upper and lower bent pieces 22 and 23 formed on the barrier 21 is fixed with a screw (not shown), the lower end of the orifice 12 is spaced apart from the base 8 by a predetermined distance. Spaced apart.

In this state, the insertion pieces 25 formed in the lower part of the bracket 24 to which the coil 18 is fixed are respectively inserted in the insertion holes 23a formed in the lower bending pieces 23, and then the locking pieces 26 formed in the upper part are inserted. Hanging the insertion hole 22a of the upper bending piece 22 completes the mounting work of the bracket 24.

After the mounting work of the bracket 24 is completed as described above, the heater cover 15 is fixed as shown in FIG. 6, and the embossed portion 15a formed at the bottom of the heater cover is connected to the upper surface of the catching piece 26 to catch the catching piece. Since the pressing is pressed, the bracket 24 does not flow in the orifice 12.

When the heating unit is mounted in the orifice 12 by the operation as described above, the control unit 10 is selected to heat the room in winter or the like, and the heating mode is selected. Since it rotates, the air in the room is sucked into the main body (1).

Accordingly, the sucked indoor air is heated while passing through the heater and then flows to the scroll 7 side through the orifice air suction hole 12b, wherein the bracket 24 installed on one side of the orifice 12 is rod-shaped. The flow path resistance due to friction with the suction air is minimized.

In the present invention, when the air conditioner is deteriorated due to deformation due to repeated thermal expansion of the coil 18 due to long-term use of the air conditioner, or a break occurs, the heater cover 15 is removed from the main body 1. Simply removing it allows replacement of the heater.

That is, when the heater cover 15 is separated from the main body 1, the heater is exposed to the space portion between the indoor heat exchanger 6 and the orifice 12, so that the operator only pulls the bracket 24 upward through the space portion. When the lower surface of the upper and lower bending pieces 22 and 23 formed in the insertion hole 22a, 23a inserted in the engaging piece 26 and the insertion piece 25 at the same time, the heater to replace the coil 18 is It is separated from the orifice 12.

After the heater is separated from the orifice 12 as described above, the coil 18 fixed to the bracket 24 is replaced with a new coil, and then the insertion piece 25 and the engaging piece of the bracket 24 are reversed as described above. 26 is inserted into the insertion holes 22a and 23a formed in the upper and lower bent pieces 22 and 23, and the heater cover 15 is assembled, thereby replacing the heater.

As described above, the present invention inserts the upper and lower locking pieces 22 and 23 into the insertion piece 25 and the locking piece 26 through a space formed between the indoor heat exchanger 6 and the orifice 12. Since it can be inserted into or taken out of the balls 22a and 23a, it is not necessary to remove the orifice 12 from the set when the coil 18 is replaced, so that the coil replacement is convenient.

In addition, since the bracket 24 to which the coil 18 is fixed when the indoor air is sucked due to the rotation of the blower fan 5 is in the shape of a rod, the flow resistance of the orifice suction side can be reduced, so that the blower fan 5 Since the load of the motor 11, which is the driving source of the motor, is minimized, and thus the input voltage of the motor can be lowered, power consumption is reduced.

In addition, since the lower end of the orifice 12 fixed to the barrier 21 is installed to be spaced apart from the base 8, it is possible to reduce the noise generated during operation.
