AIR GUIDING CONFIGURATION FOR REFRIGERATION OF MOTOR IN AIR SYMMETRIZE DEVICE OF CAR

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an air guiding configuration for refrigeration of a motor in an air symmetrize device of the car so that flowed air can affect wide area of the motor in a short time thereby having excellent effect in refrigeration of the motor, and that the above air guiding configuration therefor is simple then to have convenient assemble thereby reducing the assemble processes. Also, for the simple configuration therefor, the present invention has characterstics in retrenching troubles for generation of vibration or noise, having convenient transportation and safe-keeping process, and improving duralibility of the motor because of tight construction and good refrigeration effect.

2. Description of the Related Art

Generally, in construction of the air symmetrize device of the car, out air flowed from an out air flowing open 101 of a housing 100 is generated as strong wind in accordance withe rotation of a pan 103 of a blower by the driving force of the motor. The air generated as described above makes to be cold or warm then to be supplied through a nozzle 102 into the inner of the car along a ventilation path and a portion of the air generated thereas (that is, the air before being flowed into the ventilation path) is guided, thereby refrigerating the motor 110 of the blower. The air guiding configuration must be necessarily comprised for satisfying the above reason.

Observe the configuration of the Japan Utility Model Publication No. 26933. The above configuration corresponds to FIGs. 6 and 6a and FIG. 7 refers to another construction as indicated in the content of the another configuration being known ahead of the application date of the above Japan Utility Model. With reference to FIG. 6, the housing (blower) is comprised of an upper housing 200 and a lower housing 201 and a body 210 is assembled in the bottom surface of the lower housing 201 by a screw 207, A motor 206 is inserted into the inner of the tody 210 and a protrusion end 211 is shaped in unitary form with the body 210 to cover an upper surface of the motor 206. But, it can be seen that the protrusion end 211 can not enough enclose the upper surface of the motor 206. Also, a pan 205 is assembled in an axis of the motor 206. Further, it can be seen that a first path 212 is formed at a portion of the body 210 toward the inner of a projection 214 and a second path 213 is formed to be connected at a right angle with the first path 212. As well, an auxiliary cap 220 as shown in FIG. 6a is assembled by a screw 208 in one portion of the body 210 then to shape the first path 221 sinked and the second path 222 turned at an angle of 90 ^° with the first path 221, wherein a resistance projection 224 is made between the first path 221 and the second path 222. In addition, a third path 223 is formed while again turning at a right angle with the second path 222. As discussed above, the state assembled at the body 210 is shown in FIG. 6. Accordingly, the portion of the air generated by the rotation of the pan 205 is flowed through a small gap where the first path 221 of the auxiliary cap 220 is contaced with the projection 214 of the body 210 and the first path 221 of the auxiliary cap 220, into the first path 221 of the auxiliary cap 220 and the first path 212 of the body 210 and then, the flowed air is dashed against the resistance projection 224, thereby generating swirling agitation of air. Simultanesouly, the air is flowed into the second path 213 of the body 210 and the second path 222 of the auxiliary cap 220 while turning at the angle of 90 ^° by passing over the resistance projection 224, flowed into the lower portion of the motor 206 through the third path 223 of the auxiliary cap 220 inserted into a hole of the body 210 at the same time of again turning at the right angle of the third path 223 of the auxiliary cap 220, consequently. The air flowed into the lower portion of the motor 206 is raised by regrigerating the motor 206 to be again discharged into the pan 205, wherein the above processes are repeated. In the above process, the motor 206 is refrigerated. However, the above configuration is shaped to be complicated in that the first path and the second path are turned at the right angle with the body 210, the small hole for inserting the third path 223 of the auxiliary path 220 is made at the lower portion of the second path 213, and the projection 214 is formed to swirl the air before inflow. Also, the aforesaid configuration is complex in that the auxiliary cap 220 also is formed by turning respectively the first path 212, the second path 213, and the third path 223 at the right angle, and the resistance projection 224 is made to induce the swirling agitation of the air, wherein the auxiliary cap 220 is assembled at the body 210 by the screw 208. Due to the complicated and complex configuration, there are problems that production cost is raised as well as the assemble is not simple. Further, in account of flowing the air into the lower portion of the motor while turning at the right angle at several steps, the configuration as expressed before has disadvantages in that inflow action of the air is trioublsome and the amount of the air flowed into the motor is to be small, thereby deteroriating the refrigeration effect of the motor. Moreover, the auxiliary cap assmbled at the body by the screw 208 has important and big problem by being fragile to vibriation and impact, whereby the auxiliary cap can be seperated from the body and can generate vibriation sound on use.

To reference, upon observing the product of FIG. 7, a cap 310 having the circle plane is assembled at the bottom surface of the housing 300, a protrusion path 311 composed in form of semicircular tunnel is shaped at one portion of the cap 310 and the air is flowed through the profusion path 311. The flowed air is flowed through a hole 321 shaped at the side surface of a motor case 320 into the side surface of the motor 330, thereby refrigerating a motor 330. The product is advantageous in the light of regrigerating the motor 330 totally and however, the product has a problem in generating strong/severe vibiration from the motor 330 because the motor 330 is not inserted tightly into the inner of the motor case 320 but positioned at the medium of the motor case 320 as shown above. Also, the product has the disadvantage that the refrigeration effect of the motor is deteroriated by the small amount of the air flowed into the motor 330.

Next, FIGs. 8 and 8a refer to the Korea Utility Model Publication No. 96 38853. The configuration as set forth in the above Utility Model is similiar to that of the Japan Utility Model. Namely, the above configurations are similar to each other in that the auxiliary cap of the Japan Utility Model has action similiar to an auxilary cap 430 and a second path 402 is formed to be connected while turning at the right angle with a first path 401 at a body 400. In the above configuration, whereas inserting the auxiliary cap 430 just as covering the first path 401 and the second path 402 of the body 400, an air guiding open 431 of the auxiliary cap 430 is positioned at the upper portion of the first path 401 of the body 400. A resistance plane 432 is positioned at out portion of a motor 420 and an air flowing path 433 having the small diameter is shaped to flow the air flowed between the second path 402 of the body 400 and the resistance plane 432, into the motor 420. In comparison with the Japan Utility Model, the above configuration has only differences that the air flowed into the path is not flowed into the motor after turning at the right angle at several steps(at 4 steps) but flowed into the motor aftering turning at the right angle at third steps, and that the auxiliary cap 403 is assembled at the inner of the body 400. The above configuration is not simple, the inflow action of the air further is not good, and the refrigeration action of the motor further is not progeressed in comparison with the Japan Utility Model. But, the configuration is advantageous in reducing the assemble processes, making the production cost to be low, and making the product to be strong against vibration and impact, due to the difference in that the auxiliary cap is inserted into the body and the screw is not used. Therefore, it is noted that the afore-mentioned configuration can obtain a preferred effect in view of the above advantages.

Upon ovserving FIGs. 3 to 5, it can be concretely seen that an air flowing hole 26 is formed into the protrusion 23 and an air flowing hole 14 peneatrating the air flowing hole 26 is formed at the protrusion 13. As depicted in FIG. 2 showing the sectional view cut centering around the very middle, the air flowing hole 26 and the air flowing hole 14 are not shown in FIG. 2. However, the construction of the above air flowing holes 26 and 14 can be easily understood through FIGs. 3 to 5. For reference, the reference numeral 103 indicates a pan and the reference numeral 24 indicates a connector inserting hole for inserting a connector, the connector connecting the power supply to the motor.

As set forth in FIG. 2, the inner body 10 and the out tody can connected to each other by a screw 25 and the inner tody 10 is again connected to the housing (blower) by the screw inserting through a screw assemble hole 15, wherein the screw assemble state between the inner body and the housing is general. Thus, the screw assemble state therebetween is not shown in FIG. 2. That is, the present invention is simply composed of the innner body and the out tody and also, has not separately an auxiliary cap unlike the conventional configuration. The air flowed into 2-ways through the air flowing hole 14 of the inner body is flowed through the air flowing hole 26 of the out body into an flowed air spreading room "A" made at the inner of the protrusion unit 22. The air flowed into the air flowed spreading room "A" is directly contacted with the lower portion of the motor 110 in a short time through wide gap of the flowed air spreading room "A" reaching at Vi of the lower portion of the motor 110 as shown in FIG. 2, thereby immediately spreading the air to the direction indicated with an arrow (as indicated with the dotted line), raising the spreaded air, and refrigerating the total of the motor.
