Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioning deodorizing device for an automobile for dispensing volatile components of a volatile deodorizing aromatic agent into the inside of a ventilation system path from an inlet to an outlet of an air conditioner.

Since the cabin of a car forms a very narrow sealed space, it is important to create a comfortable environment with regard to odors.

Conventionally, as air conditioners installed in automobiles are used for many days, the air discharged from the air outlet often contains a foul odor that is extremely unpleasant to passengers. . This is due to various bad odors contained in the air sucked in through the intake port, especially when internal air is used for circulation. It adheres to other parts of the evaporator and is condensed, and it comes out of the air outlet and is
This is for the purpose of coming. After turning on the air conditioner, there is a point in time when the temperature and humidity of the air are at their most sensitive until the temperature and humidity of the air are sufficiently adjusted. We have no choice but to pass the 4-jin stage. Therefore, at that point, the degree of perceived malodor increases. Due to these phenomena, when riding in a car equipped with an air conditioner, there are complaints that a bad odor is felt when the air conditioner is activated.

To solve this problem, the adsorption method based on activity has been widely used as a deodorizing method for relatively small rooms or closed spaces. It is difficult to make sufficient contact with the air.In addition, air filters are often used for air flowing through ducts, but this structure increases ventilation resistance due to the air filter, so it is necessary to make sure that the blower fan has sufficient capacity. There must be enough room, and if a filter is installed in a relatively small capacity car air conditioner, the burden on the blower fan will be too much, making it difficult to use for practical purposes.In addition, it is difficult to use for deodorizing the interior of a car. Although various fragrances are used, the fragrance components in all of them constantly evaporate and diffuse, which can cause discomfort to passengers.

The present invention was made in view of the above points, and the object is (1) to provide a device that can blow air and also allows the deodorant to be replaced extremely easily.

Another object of the present invention is to provide a device that can easily stop the introduction of deodorizing volatile components into the ventilation system of an air conditioner, or easily adjust the amount of the deodorizing volatile components mixed in.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 indicates the entire automobile air conditioner, and 2 indicates a blower fan, which is driven by a motor 8a.

Reference numeral 3 denotes an inside/outside air switching damper, which selectively introduces either the outside air from the outside air intake port 3a or the inside air from the inside air intake port 8b into the inside of the vehicle. This introduced air is blown to the evaporator 6 side of the shift unit by the blower fan 2. When the air blowing static electricity passes through this evaporator, the heat of vaporization of the refrigerant is removed and the air is cooled. Drain water generated on the surface of the evaporator due to this cooling is discharged to the outside of the vehicle through a drain port (not shown).

Reference numeral 5 denotes a heater core of a heater unit, which heats air using the cooling water of the own e-vehicle engine as a heat source.A bypass passage 6a is formed in either side of the heater core 5 to allow air to flow without passing through the heater core 6. . 6 is an air mix damper for temperature control, which adjusts the flow rate of air 9C (cold air) passing through the bypass passage 5a and the flow rate of air (i2! wind) passing through the heater core 5 to adjust the blowout static temperature. be.

The fan is a mixing chamber downstream of the heater core, which mixes cold air and hot air.

8 is an upper air outlet that blows cold air toward the occupant's head and thorax;
Reference numeral 9 denotes a downward outlet that blows warm air toward the occupant's feet. 1O is an air outlet switching damper that selectively opens and closes the secondary outlets 8.9.

The inside/outside air switching damper 8, the air mix damper 6, and the outlet switching damper 10 are remotely controlled via a link mechanism or the like by an operating lever (not shown) provided on the air conditioning control spring μ inside the vehicle. In addition, the rotational speed of the blower motor ga is also controlled by a switch provided in the air conditioning control panel IvK inside the vehicle.

Reference numeral 11 denotes a deodorizing device containing a volatile deodorizing aromatic agent, and in this example, it is installed outside the duct immediately downstream of the evaporator 4, and is installed at the bottom of the instrument spring μ in the passenger compartment. positioned. As clearly shown in FIGS. 2 to 4, this deodorizing device 11 infiltrates a flat pad 14 made of a highly absorbent Fe A/) material or the like with a volatile deodorizing aromatic agent.
This pad 14 is placed in a bag 15 made of a breathable low-pressure polyethylene film in a state that matches its shape, and this is stacked in eight layers, and then placed in a small plastic case 16. There is. This plastic small case 16 is divided into an upper case laa and a lower case 16b, but they are connected to each other by a hinge part 17 so that they can be opened and closed, and the upper case 16 & and the lower case 16b are molded as one piece. ing. Upper case 1 of this small case 16
On the 6 & side, there are vents IBm and Iab that allow the deodorizing and aromatic to volatilize and diffuse into the air, and these vents Lsa and Tab can be attached to the duct 1g. Pipes xea and tab are molded on the. In addition, an elastically deformable pawl go is integrally molded on the upper case side tea, and this pawl piece O is formed in a notch gBc formed in the lower case xab when the upper case lem and the lower case lab are fitted together. It has a locking structure. Further, the small case 16 is attached to the duct lj by adhesive means g2 such as double-sided tape or Velcro attached to the upper case 1181.
It is removably fixed to the outer wall of l. Here, the eight pipes 19m and 19b of the small case 16 penetrate the opening of the duct 1m and protrude into the duct 12, and the suction pipe 19a receives the air flowing in the direction of the arrow in the duct 1g. It is fixed in a position where it can be easily inserted, and its tip is formed diagonally to receive air.

Further, the tip of the pipe le'b on the discharge side is formed obliquely in the opposite direction so that air can be easily discharged.

A support pin 28 is integrally formed in the upper case 16 &, and a mounting portion 24 of the lever 14 is attached to this support pin 33.
& are rotatably connected, and on both sides of this mounting part g+a, there are valve parts g4b and 14 for opening and closing the divergence ports lsa and lsb.
0 is set. The handle g4d of the lever 24 protrudes to the outside of the small case 16 and can be manually operated from the outside.

! b is a line part for taking out the lever B4 to the outside, and is formed between the upper and lower cases tea and lab.

Numeral 86 is a protrusion formed on the inner surface of the upper and lower cases laa and tab, which holds the bag 16 containing the pad 14.

Next, the operation of the above configuration will be explained. First, when the air conditioner is not operating, that is, when the fan 2 is not operating, when the lever B4 is set to the open position shown in FIG.
Since the openings a and 18b are opened, the volatile components of the deodorizing aromatic agent are volatilized and diffused through the vents lsa, tab, pipe xea, and 19b, and the downstream side of the evaporator chamber of the air conditioner is filled. When the air conditioner is turned on and the fan 8 is activated, air flows through the ventilation path and passes through the evaporator, mixing with the volatile components of the deodorizer filling the downstream area and exerting a deodorizing effect. On the other hand, when the fan 2 is in operation, one of the pis 119 & is provided at a position where it is likely to receive the dynamic pressure of the air flowing in the direction of the arrow in the ventilation passage, so that the air that has passed through the evaporator of the air conditioner is Part is this pipe 19&
It flows into the small case 16 from above, exits from the other discharge pipe 19b along with deodorizing components, and mixes with the air flowing downstream of the evaporator, exerting a deodorizing effect. When lever N4 is moved to the closed position shown in the lIgs diagram, lever B4
The valve parts g4b and g4c of the small case 16 are the divergence ports t8m,
Since 18b is completely closed, the deodorizing effect can be stopped. Furthermore, by selecting the rotational position of the lever 840, the opening areas of the emission ports xsa and tab of the small case 16 are changed, so it is possible to appropriately adjust the amount of deodorization. Since the deodorant always emanates and fills the inside of the small case 16, the deodorizing component can be continuously mixed in at a substantially constant concentration even while the fan 2 is in operation. When the deodorant air freshener runs out of ingredients and you want to replace it with a new one, remove the claw piece 20 attached to the upper case 16& from the notch 21 provided in the lower case 18b. The deodorant can be separated using the hinge part 17 as a fulcrum, and the deodorant can be taken out and replaced.

Note that the present invention is not limited to the above-described embodiments, and can be implemented in various ways. For example, the mounting position of the small case 16 is not limited to the downstream side of the evaporator, but may be installed in the ventilation system path of an air conditioner. Any location within the evaporator, such as the upstream side of the evaporator, the air mixing chamber 7, etc., where a flow of air can be obtained may be used.

Also, as shown in Figure 2, connect the pipes 19a, 19t) with a suitable tube 27, and attach the pipe 28 attached to the tip of the tube g7 to the duct 1j1 so that it protrudes into the duct 1j1. Okay, small case 16
It may be installed in a position where it is easy to operate, such as under the passenger seat undertray or at the bottom of the instrument panel.

As explained above, according to the present invention, the duct of the air conditioner)
By utilizing the flow of air within 1 g, a reliable deodorizing effect can be achieved without putting a burden on the fan capacity of the air conditioner. In addition, since the deodorizer continues to emit a certain amount even when the air conditioner is not operating, the duct 12 is filled with its volatile components, and when the air conditioner is started, it is immediately blown out. It can play a great role in eliminating initial bad odors, and furthermore, the deodorizer can be installed, removed, and replaced very easily from outside the air conditioning system, and other excellent effects can be obtained.

Furthermore, the present invention has the great effect that by rotating the lever 24, the mixing of the deodorizing volatile components can be stopped and the amount of the mixing can be freely adjusted.
