A valve member for guiding the valve member to a predetermined position in a radial direction of the valve member; The valve member includes a valve member, a spring, a backward movement member, a backflow preventing member,

One embodiment of the present invention will be described in detail with reference to the drawings.

1, the internal / external stunning box 3 having the outside air intake opening 1 and the inside air intake opening 2 is referred to as a " A fan 5 driven by a floor motor 4 is installed in the box 3 and an inside and outside stunning door 6 for selecting the entry and exit of air is provided. A cooler unit 9 is disposed at the next stage of the floor unit 7 with the communication duct 8 interposed therebetween. The cooler unit 9 is provided with an evaporator 11 as a heat exchanger in the cooler housing 10.

A drain port 10a is formed in the cooler housing 10 just under the evaporator 11. [ The evaporator (11) is an evaporator connected to the refrigeration cycle and acts to deprive the surrounding heat. The heater control unit 12 is connected to the next stage of the cooler unit 9 in a communicative manner. The unit 12 has a heater core, an air mix door, a bend door, a teproaster door, a heater door, and a mixing chamber, and discharges the conditioned air (cold air or hot air) The roaster outlet, the bend outlet, and the heater outlet to the required position in the vehicle.

In the vehicle air conditioning system having the above-described configuration, a communication duct (8) located on the upstream side of the evaporator (11) as an example of an air entry path is provided with a nozzle 13).

As shown in FIG. 2, the nozzle 13 is made of synthetic resin in a relatively thin and long cylindrical shape with its tip end 13a closed. Therefore, a portion of the nozzle 13, which faces the front surface of the evaporator 11, (14) is pierced. The nozzle neck portion 13c near the flange portion 13b is formed into a tapered tubular shape having a small diameter at the tip end 13a side and a large diameter at the flange portion 13b side, A plurality of protruding portions 13d of triangular cross-sectional shape that are blocked by the sealing member 8 are integrally formed. Therefore, the nozzle 13 can be inserted into the communication duct 8 by one-touch operation or simply by punching a small hole. Needless to say, it is needless to say that a joining means for joining the flange 13b to the communication duct 8 may be used in combination. The flange portion 13b is integrally formed with a projection 13e to be displayed when the nozzle 13 is fitted substantially in coincidence with the ejecting direction of the solvent fluid a. In order to prevent the nozzle 13 from being erroneously inserted when the nozzle 13 is inserted, So that the nozzle 13 can be aligned.

The distal end of the rubber hose 15 (solvent supply path) is fixed to the joint portion 13f of the nozzle 13 by effectively using the elastic tightening force (elastic restoring force). The inlet of the rubber hose 15 is led into the vehicle and is fitted to a small portion near the driver's seat or near the passenger seat as shown in Fig. 3, for example, a small portion such as a front surface, a side surface or a bottom surface of the instrument panel 16 (17) made of synthetic resin as a storage means which is fixed by a fixing member (adhesive fixing, bolt fixing, clip fixing, fixing by double-sided tape). The housing member 17 is formed in a structure in which the filling container A of the solvent as the source material is completely separated from and independent of that shown in Fig. 6, and its specific structure is as shown in Figs. That is, the flange portion 20 is integrally formed with the ring-shaped spacer 19 sandwiched between the main plate 18 and the cylindrical guide portion 21 formed at the center of the main plate 18 and the outer periphery of the spacer 19 A solvent passage 23 is formed between the joint portions 22 projecting outward from a part of the main plate 18. A ring-shaped holder 25 for supporting the lid member 24 is integrally formed on the spacer 19 side of the main plate 18 So as to constitute the main body side of the receiving member 17. The guide part 21 has a nozzle N of the handy type container in which the filling container (A) gas is sealed at the time of supplying the solvent, and the guide part 21 has a large diameter outside the guide part 21 A tapered portion 21a having a small diameter inside is formed and an annular end portion 26 for preventing the nozzle N from being excessively fitted is formed inside the edge of the tapered portion 21a. The member 24 is screwed on the holder 25 so as to be freely detachable from the holder 25. The inner surface of the lid member 24 is provided with a closed portion 23a for closing the tapered portion 21a of the guide passage 21, And the outer peripheral surface of the lid member 24 has a rough surface in order to facilitate the detachment of the member 24.

In FIG. 5, the knuckle processing tool 24b is shown as an example of the rough processing, but other rough processing may be used.

4, the outer shape of the joint part 22 is formed in a shape to fit into the joint part 22 because of the structure in which the taper cones are connected in a plurality of ways, and the entrance of the rubber hose 15 is fixed to the joint part 22 by using its elastic tightening force It is fixed. As described above, the filling member A is completely separated from the handy type filling container A so that the filling container A can be stored in a glove box and a console box of a vehicle.

Examples of the solvent fluid (a) include a liquid detergent, a foam-like cleaning liquid (water, phosphoric acid, soffanol, an appropriate amount of propylene glycol monomethyl ether MFG, etc.), cleaning water, a fragrance, a medicine, a deodorant, , Antibacterial agents, bactericides, fungicides, and the like can be used. In addition, it is a matter of course to use only the filling container sealed with a directional solvent in order to secure only the direction effect in the vehicle. Each of the elements 13, 14, 15, and 17 shown in FIG. 2 may be handled as a kit and attached to the vehicle during the respective elements 13 to 15, 17, or may be integrally formed in advance in the manufacture of a vehicle.

6, when the evaporator 11 is cleaned, the lid member 24 is removed from the accommodating member 17 shown in Fig. 3. Then, as shown in Fig. 6, When the nozzle N of the nozzle A is guided by the tapered portion 21a of the guide portion 21 and is pushed into the solvent passage 23 to push the cleaning fluid from the nozzle N, the cleaning fluid passes through the solvent passage 23 And is discharged to the front surface of the evaporator 11 from the plurality of air outlets 14 after the air is introduced into the nozzle 13 at the tip end thereof so that the complicated fin of the evaporator 11 is supplied to the rubber hose 15, The fluid after the cleaning treatment is drained to the drain port 10a just below the evaporator 11. The fluid is then drained to the drain port 10a immediately below the evaporator 11. [ If necessary, a drain hose may be connected to the drain port 10a to discharge the cleaned fluid out of the vehicle.

Here, when the fan 5 is driven while the cleaning fluid is being discharged through the air outlet 14, the cleaning fluid reaches the deep inside of the complicated fin or the inside of the evaporator 11, so that the cleaning effect can be further enhanced.

The order of using the solvent fluid (a) may be a chemical such as a cleaning agent in the form of a foam, a disinfectant or a disinfectant in this order, a cleaning agent in the form of a foam, a cleansing water and a chemical agent may be used in this order, It is also possible to use air freshener in this order, and after the cleaning treatment, air, hot air, hot air or cold air may be supplied to the inlet end of the rubber hose 15 to dry the evaporator 11.

Especially when the solvent fluid a ejected from the nozzle 13 is set as a foam-like cleaning fluid, even if the dimension of the nozzle 13 is relatively higher than the total inner height of the communication duct 8 as shown in FIG. 7, 13, the foam-like cleaning fluid spreads over the entire front surface of the evaporator 11 as shown in FIG. 7 due to the characteristics of the foam fluid, It can be effectively cleaned deep inside. As a result, the size of the nozzle 13 can be made compact and the attachment of the nozzle 13 to the vehicle air conditioner can be improved.

In other words, the rubber hose 15 is connected to the nozzle 13 fitted in the upstream of the evaporator 11 in the air inlet / outlet path (the path from the air inlet 1 or 2 to the evaporator), and the inlet of the rubber hose 15 is filled Since the housing member 17 separated from the container A is made to fix the housing member 17 to the in-vehicle unit, the solvent source such as the filling container A is separated from the housing member 17 and the temperature rises And can be housed in a storage space such as a glove box and a console box, thereby preventing rupture and breakage of the solvent source. In addition, when the filling container A is used, the filling container A is pulled out of the receiving space and fitted into the nozzle guide portion, thereby improving the interior environment of the vehicle by cleaning the evaporator 11 or supplying a functional agent or other functional solvent.

As the solvent fluid (a), a single or a mixture of a solvent such as a liquid detergent, a foam cleaner, a fragrance, a deodorant, a deodorant, a deodorant, a disinfectant, a disinfectant, a fungicide, (A) ejected from the nozzle 13, various functions such as a cleaning function or a direction, deodorization, sterilization, or mold prevention can be obtained, and it is possible to purify the inside of the air conditioner, to prevent occurrence of strange odor And bacterial effect and antifungal effect can be secured.
