Description

[0001] The present invention relates to a coupling structure of a fan driving motor for controlling the rotational speed of an air conditioner,

The present invention relates to a coupling structure and a method of coupling a resistor for controlling the rotation speed of a fan driving motor of an air conditioner and more particularly to a method of forming a coating layer by applying an insulating liquid on one surface of a facing heat sink and a cover, Since the resistor main body is formed by combining the resistor circuit pattern between the heat sink and the cover, it is possible to improve the productivity of the resistor main body by reducing the work process and cost of the resistor main body, and by directly forming the coating layer on the heat sink and the cover, And to a coupling structure and a coupling method of a resistor for controlling the rotation speed of a fan-driven motor of an air conditioner capable of rapidly radiating heat generated from a pattern to the outside.

Generally, a cooling or heating temperature control device is indispensably installed in an interior of a vehicle as an air conditioning means, and a cold / warm air flow generated through a cooling / heating device installed in the vehicle is transmitted through a fan .

In order to maintain the temperature of the vehicle room in an optimal condition compared with the outside temperature in the case of forced supply of such warm and cool air currents to the interior of the vehicle, a step of about 3 ~ 4 stages such as breeze, So that the driver can adjust the supply strength of the hot and cold air.

In order to enable the stepwise operation, it is realized by selecting and setting the rotational speed of the 'fan' installed as hot / cold forced force supply means and the motor installed as the driving means of the fan in steps, A resistor is used.

The resistor is composed of a resistor body and a base to which the resistor body is coupled at the top, as disclosed in the patent application No. 1195392 filed by the applicant. A conventional resistor will be described with reference to FIG. 1 or FIG. 2 as follows .

As shown in FIG. 1, the base 1 is formed with a plurality of main power connection terminals 10 to which a resistor terminal 61 provided in the resistor main body 20 is coupled.

The resistor main body 20 is coupled to the upper surface of the base 1 provided with the main power connection terminal 10.

The resistor main body 20 includes a resistor circuit pattern 60 having a resistor terminal 61 protruded from the lower end of the resistor main body 20 and coupled to the main power connection terminal 10, A heat sink 30 for dissipating heat generated in the resistor circuit pattern 60 to the outside and a heat sink 30 for protecting the resistor circuit pattern 60 coupled to the inside of the heat sink 30, As shown in Fig.

A plurality of coupling grooves 31 are formed on both sides of the heat sink 30 so that the cover 40 is coupled to the inside of the cover 40. A coupling portion 41, 40, respectively.

A resistor circuit pattern 60 formed in a thin plate shape as shown in Fig. 2 is formed between the heat sink 30 and the cover 40, which are coupled in this manner.

At this time, an insulating plate 50 made of a main material is combined with the resistive circuit pattern 60 which is coupled between the heat sink 30 and the cover 40 so that power flowing in the resistive circuit pattern 60 is transmitted to the heat sink 30, And the cover (40).

That is, the resistor circuit pattern 60 is coupled between the heat sink 30 and the cover 40 in a state where the insulating plate 50 made of the asbestos main material is coupled so as to surround the resistor circuit pattern 60.

Therefore, the resistor terminal 61 provided at the lower end of the resistor circuit pattern 60 and the main power connection terminal 60 provided at the base 1 are connected to each other so that even when the power source flows the resistor circuit pattern 60, It is possible to prevent the power flowing in the circuit pattern 60 from flowing to the heat sink 30 and the cover 40.

A thermal fuse 70 for short-circuiting power when an abnormality occurs in the fan driving motor is combined with the resistance circuit pattern 60 coupled between the heat sink 30 and the cover 40, (70) is joined by spot welding between connection end portions (62) extended on the resistor circuit pattern (60) as shown in Fig.

At this time, on the upper portion of the cover 40, a fixed support portion 42 for fixing the thermal fuse 70 coupled to the connection end portion 62 by spot welding is formed in a streamlined shape.

The combined state of the conventional resistor body 20 configured as described above will now be described.

The resistor circuit pattern 50 is coupled to the inside of the heat sink 30 after the insulating plate 50 made of the asbestos material is coupled so that the thermal fuse 70 is spot welded with the resistor circuit pattern 60 .

The cover 40 may be coupled to the heat sink 30 so that the resistor circuit pattern 50 is connected to the heat sink 30 through the heat sink 30 such that the engaging portion 41 is fitted into the coupling groove 31 provided in the heat sink 30. [ 30 and the cover 40. As shown in Fig.

The resistor body 20 thus combined is coupled to the base 1 to form a resistor.

However, the problem of the resistor coupling structure for controlling the fan driving motor rotational speed of the conventional air conditioner is that the resistor circuit pattern 60 having the insulating plate 50 coupled thereto after the insulating plate 50 is wrapped around the resistor circuit pattern 60 Since the insulating plate 50 to be coupled to the resistor circuit pattern 60 must be manufactured by a separate operation, the work process is complicated and the productivity is increased due to an increase in manufacturing cost. There is a problem that degradation occurs.

Particularly, since the insulating plate 50 surrounding the resistance circuit board 60 is made of the main material, the operator who manufactures the insulating plate 50 is exposed to asbestos and is exposed to various kinds of diseases such as pleurisy, pleura, asbestos, lung cancer, .

In order to solve the above problems, according to the present invention, there is provided a resistance circuit pattern in which a coating layer is formed by applying an insulating liquid on one surface of a facing heat sink and a cover, and a thermal fuse is coupled between the heat sink and the cover, The manufacturing process and cost of the resistor main body can be remarkably reduced to improve the productivity of the resistor main body, and a coating layer is formed directly on the heat sink and the cover to heat the heat generated in the resistor circuit pattern to the outside It is not necessary to separately manufacture an insulating plate composed of asbestos as in the prior art. Therefore, it is possible to prevent the occurrence of various diseases such as pleurisy, pleural membrane, asbestos, lung cancer, Fan-driven motor for adjusting the rotational speed of the air conditioner And a method of combining the same.

Since the coating layer is directly formed on the heat sink and the cover, the heat generated in the resistance circuit pattern can be quickly dissipated to the outside.

In addition, since a coating layer is formed on the heat sink and the cover, it is not necessary to separately manufacture an insulating plate composed of asbestos as in the prior art. Therefore, various diseases such as pleurisy, pleura, asbestos, lung cancer, Can be prevented from being generated.

[

Since the coating layers 111 and 121 formed by applying the insulating liquid directly to the heat sink 110 and the cover 120 are formed, the insulating plate 50, which is coupled to the resistance circuit pattern 60, It is possible to reduce the production cost of the resistor body 100 and to improve the productivity and the cost.
