Description

  The present invention relates to an apparatus used during maintenance of a car air conditioner.

  Each processing such as cleaning of a wall-mounted air conditioner in a normal house is performed by a so-called disassembly and cleaning method that is performed in steps of disassembling, curing, cleaning, drying, and assembling the air conditioner body. Such an air conditioner has the main equipment in the room, and the air conditioner itself is relatively large and can be easily disassembled. Therefore, the interior can be easily cleaned while visually confirming.

  A car air conditioner is an air conditioner attached to a car. Such a car air conditioner is installed in a limited space, and is usually a blower fan such as a sirocco fan provided inside a vehicle as shown in FIG. The air is sucked through the air filter by the air, the sucked air is blown out from the blower outlet, and the blown air is sent to a heat exchanger such as a heater or a fin (evaporator) having a large number of fins to be heated or cooled. Then, heated or cooled air is blown out from the front of the main body toward the room. The water agglomerated in the heat exchanger is received by the drain pan provided under the heat exchanger without being scattered around and is discharged to the outside by the drain.

In addition, dirt inside the car air conditioner that cannot be removed by an air filter, such as dust, dust, and soot from normal use, and dirt that flows from outside such as exhaust gas and dust always adhere to and accumulate. ing.
In addition, the interior of a car air conditioner always contains moisture, and the dirt accumulated in the fins with particularly high humidity is a good hotbed for mold, bacteria, mites, and the like. For this reason, a bad smell may fill the room during driving. Therefore, in order to have a healthy and comfortable environment in the room, it is essential to clean the inside of the air conditioner.
In particular, the fin portion that performs heat exchange has a large total area of about 900 m ² , and even if the filter portion of the air conditioner is removed, it is difficult to visually observe the depth of the fin gap. It was difficult to perform a process such as cleaning.
Therefore, it is never something that a car user can do by himself, and depending on the car model, even a filter cannot be removed, it is difficult to clean or replace the filter, and it may be necessary to make a hole from under the car .

As described in Patent Document 1, although it is for an indoor air conditioner for a house, an injection container with a long nozzle for processing fins of an air conditioner is known. The tip of the nozzle moves only by the movement of the hand holding the injection container, and such an injection container with a nozzle is sufficient for an indoor air conditioner for a house where the fins can be visually confirmed. .
However, the fin portion for exchanging heat of the car air conditioner is installed in such a depth that it cannot be visually confirmed, and even if the thing for the indoor air conditioner for a house is diverted, the fin portion cannot be processed.

JP 2004-26278 A

Unlike an indoor air conditioner for a house, when processing a car air conditioner, there is a problem in that the work time required for the disassembling work of the car air conditioner becomes longer and costs increase. Furthermore, there are many cases in which the car air conditioner main body is not cleaned unless it is very dirty, and there are many situations in which dirty air has to be supplied indoors for a long period of time.
In addition, it is extremely difficult for a user of a car air conditioner to perform cleaning, and it is maintenance of a car air conditioner in which a filter attached to the vicinity of a fin for heat exchange can be replaced at most. In addition, it was necessary to treat the details of the heat exchange fins and the like when adding deodorant and aroma to the interior of the car air conditioner. It is difficult to clean, deodorize, disinfect, and antibacterial treatment more easily, uniformly and without disassembling the parts that it has, and without contaminating the surroundings and workers' clothes, etc. Met.
Therefore, an object of the present invention is to solve these problems and to obtain an apparatus for performing processing such as cleaning, deodorization, sterilization, and antibacterial on the inside of a car air conditioner by a simpler method.

The inventors of the present invention have found that by connecting a specific long tube to the injection container, the cleaning liquid can be efficiently injected up to a portion having a fine structure such as a heat exchange fin of a car air conditioner. Invented the invention.
1. A car air conditioner processing apparatus comprising: a spray tube having a hard portion and a soft portion provided at a tip thereof connected to a spray container in which a processing liquid is stored.
2. 2. The car air conditioner processing apparatus according to 1, wherein the hard part is a soft part and the outer periphery of the tube is covered with a hard member.

ADVANTAGE OF THE INVENTION According to this invention, a process liquid can be sprayed more widely and uniformly with respect to the inside of a car air conditioner, especially the part which has fine structures, such as a fin for heat exchange.
Therefore, it is possible to perform internal coating, antibacterial, sterilization, deodorization, etc. without disassembling the car air conditioner. There is no fouling.

The present invention is a car air conditioner processing apparatus having an injection container and an injection tube, and in particular, an apparatus for processing fine and complicated structural parts such as fins for exchanging heat inside the car air conditioner.
The apparatus of the present invention has a size that allows a user to carry out an injection operation with one hand.

(Jet container)
As injection containers, aerosol injection containers using propellants such as liquefied petroleum gas (LPG), dimethyl ether, nitrogen, carbon dioxide, compressed air, isopentane, trigger dispensers and finger dispensers using mechanical content compression mechanisms, etc. The injection container etc. are mentioned.
Above all, from the viewpoint of operability, by pressing the injection button attached to the upper part of the container body, the liquid content is injected from the nozzle part to the outside with gas pressure such as liquefied natural gas filled in the container body. It is preferable to use the aerosol spray container described above.

An injection tube is connected to the nozzle portion for ejecting the treatment liquid in the injection container, and the injection tube is composed of a hard portion and a soft portion connected to the tip thereof.
As a result of connecting this injection tube, the total length of the processing liquid supply part for processing liquid injection becomes longer, and the processing liquid to be sprayed spreads further, and the injection tube is bent more flexibly. It is possible to reliably reach the gap between the heat exchange fins of the car air conditioner.
Furthermore, the tip of the spray tube is a soft part, the processing liquid passes through the spray tube at a high pressure, and the soft part that is the tip part of the spray tube in particular due to the momentum and reaction that is jetted in the car air conditioner, It exhibits behavior such as irregular vibrations, turning and sudden changes in direction. Since the processing liquid is ejected while exhibiting such behavior, the processing liquid spreads over the entire surface of the car air conditioner, particularly the gaps between the fins, and the necessary processing can be performed.
At this time, the shape of the tip of the soft part where the processing liquid is discharged may be a structure in which the tube is simply cut perpendicularly to the length direction, or a structure in which the shape is cut obliquely in the length direction. Alternatively, one or more holes for injecting the treatment liquid may be provided on the side surface of the tube at the tip of the soft part. Due to the structure of these tips, when the processing liquid is ejected, the movement of the soft portion irregularly can be adjusted by the reaction caused by the momentum of the ejection.

The degree of softness of the soft part is that the direction of the tip of the soft part can be flexed freely, and further, the reaction of the process liquid ejected from the tip of the soft part due to the momentum of the process liquid passing through the inside. It is necessary that the degree of irregularity is changed like the above behavior.
The hardness of such a soft part is required to be A90 ° or less, preferably A50 ° or less, as measured by a condition based on JISK6253. In the case of a material harder than A90 °, the tip of the soft part cannot be freely changed in the car air conditioner due to the reaction of the sprayed processing liquid.
In order for the soft part to be freely bent in the car air conditioner, the length is preferably 150 mm or more. If it is less than 150 mm, depending on the model of the car air conditioner, it may be difficult for the tip of the soft portion to change its direction irregularly due to the reaction of spraying the processing liquid.

The spray tube of the present invention is connected to the nozzle part through a sufficiently long hard part, and the hard part is inserted into the car air conditioner so that the inside thereof can be bent and the soft part can be held. Since it has hardness, a soft part can be made to reach a fin. However, it is possible to provide an air conditioner stopper on the hard part so as not to put it in the car air conditioner. Therefore, the hard part needs to have a certain degree of hardness, and the hardness depends on the conditions based on JISK6253. The measured value is, for example, D50 to 60 °.
Therefore, the hard part itself can be made of a hard material made of a material different from the soft part, or a tube made of the same material as the soft part is covered with another member to make this hard part. You can also.
At that time, another member is used as a guide tube and covered with a tube made of the same material as the soft portion, or the same tube as the soft portion, so that the required hardness is obtained as a whole.
At this time, the guide tube may be slidably provided around a tube made of the same material as the soft portion or a tube made of the same tube as the soft portion, or may be fixed and integrated. In the case of sliding, a guide tube stopper for regulating the sliding range can be provided on the spray tube depending on circumstances.
In addition, although the length of the whole injection tube including a soft part and a hard part can be adjusted in consideration of the height etc. of the installation place of an air-conditioner, it is the length of about 50 cm-2 m normally. These lengths are also adjusted according to the type of car air conditioner and its installation location.

(Processing liquid)
The treatment liquid stored in the spray container is selected from, for example, anti-fungal agents, disinfecting / anti-bacterial agents, deodorants, fragrances, cleaning agents, insecticides, insecticides, and anti-miticide agents. In addition, a liquid containing one kind or two or more kinds can be given.
From these treatment liquids, a treatment liquid can be selected and used according to the treatment purpose of the car air conditioner.

(Example)
An embodiment of a car air-conditioner processing apparatus and a processing method of a car air-conditioner using the processing apparatus of the present invention as described above will be described below with reference to the drawings.
The apparatus shown in FIG. 1 is a car air conditioner processing apparatus 1 which is an example of a car air conditioner processing apparatus of the present invention.
This car air-conditioner processing apparatus 1 includes an injection container 2 in which a processing liquid is stored, an injection button 3 that is provided on the upper part of the injection container 2 and that injects the processing liquid in the injection container 2 by pressing down. An injection tube 4 provided in the upper part of the injection container 2 and connected to a nozzle for discharging the processing liquid to the outside of the injection container 2 and the nozzle tip, and inserted into the car air conditioner through which the processing liquid passes; The guide tube 5 fitted in the middle portion of the injection tube 4, the guide tube stopper 6 that regulates the movement of the guide tube 5, and a part of the guide tube 5 are covered so that the guide tube enters the car air conditioner too much. It has an air conditioner stopper 7 that regulates this.

The car air conditioner to be processed using the car air conditioner processing apparatus shown in FIG. 1 is a car air conditioner having a structure as shown in the schematic diagram of FIG.
3, the operator inserts the injection tube 4 into the car air conditioner through the air blower of the air conditioner and places the tip of the injection tube 4 close to the fins, and the injection button of the injection container 2 shown in FIG. The processing liquid is sprayed into the air conditioner by pushing 3 or the like. At that time, due to the momentum of the processing liquid sprayed from the tip of the spray tube, the soft portion of the flexible spray tube changes its direction irregularly as shown in the circle of FIG. As a result, it is possible to process the fins with the processing liquid while the direction of the liquid feeding tube irregularly changes in the car air conditioner.
Then, while spraying the processing liquid, the operator can supply the processing liquid to the fins of the car air conditioner and the entire surrounding area by moving the position of the soft portion at the tip of the spray tube up, down, left and right by the operator. .
As a result, when the injection nozzle is inserted into the car air conditioner fin from the air blowing port in the vehicle using the apparatus of the present invention and treated with the treatment liquid containing the antibacterial agent, the odor generated by mold and bacteria is eliminated. did it. Moreover, the antibacterial property which was excellent in the fin surface with respect to Gram positive bacteria, Gram negative bacteria, yeast, and mold | fungi was able to be exhibited.

Of course, the tip of the spray nozzle can be positioned in the vicinity of the air blowing port in the vehicle, and the processing liquid can be sprayed at that position. In this case, however, the tip of the nozzle is far from the fin, and the air passage for blowing air may be bent instead of a straight line. Since it adheres to the wall surface of the passage, the heater surface, etc., the amount of the processing liquid that can reach the fins to be processed becomes extremely small.
Therefore, when the treatment liquid containing the antibacterial agent is used, the deodorization effect and the antibacterial effect equivalent to the above-described deodorizing effect according to the present invention cannot be exhibited, and the growth of various bacteria on the fin surface and the generation of the bad odor accompanying it. Could not be prevented.

  When the air conditioner is processed by the car air conditioner processing apparatus of the present invention, after the processing liquid is supplied and processed around the fins of the car air conditioner, although not shown, condensed water or the like installed below the fins is collected and discharged. Therefore, excess processing liquid or the like can be discharged to the outside through a water receiving portion (drain pan) for draining and a drain connected thereto.
