JPS6112421A - Aromatic deodorizer - Google Patents

Abstract

PURPOSE:To perform sufficient deodorization only when required while to prevent idle volatilization of aromatic deodorant by providing means for containing heat-sensitive aromatic deodorant and heating as required in the air feed path of an air-conditioner. CONSTITUTION:Upon turning on of an air-conditioner switch 20, an electromagnetic clutch 19 will function to start supply of refrigerant to an evaporator 7. At the sametime, a blower fan 6 is rotated by a motor 18 to feed the air through a suction port 2a into the air feed path 5. While a timer 22 will also function simultaneously to heat a heater 17 by the current fed from a battery 21 thus to heat an aromatic deodorizer 10 arranged in said path 5. Consequently, volatilized agent is blown through a blow-out port 4a into the cabin. Upon elapse of predetermined time, the timer 22 will open the circuit to stop heating of the heater 17. Upon lowering of temperature of the evaporator 7 to produce cleanly conditioned air, said deodorizer 10 will stop volatilization.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a deodorizing/fragrance device for eliminating bad odors that occur when starting up an air conditioner.

Conventionally, in air conditioners, during heat exchange, foreign matter such as dust in the air or cigarette tar adheres to the evaporator, etc., and bacteria adhere to the foreign matter, condensing on the evaporator surface, and then being cultured by the moisture. Due to the bacteria, a strange odor occurs in the blown air from the time the evaporator is started until the temperature of the evaporator drops below a certain level. For this reason, as disclosed in Japanese Patent Application Laid-open No. 58-78821, a case that can manually adjust the opening area is provided in the ventilation duct, and a volatile deodorizing aromatic agent is housed in the case. A deodorizing device has been proposed.

Problems to be Solved by the Invention However, in the deodorizing device, although it is possible to adjust the volatilization amount of the deodorant and aromatic agent by adjusting the opening area of the case, It is not possible to appropriately control the amount of volatilization. At the time when this careful harmonization device is started, when the deodorizing fragrance is most needed, sufficient volatilization cannot be obtained, and at low temperatures when even a small amount of volatilization is insufficient, more volatilization occurs than necessary, and the fragrance of the air freshener fills the room. However, there are concerns that this may lead to disadvantages such as discomfort.

The present invention is different from conventional deodorizing devices, and it is an object of the present invention to provide a deodorizing and aromatic device that can freely control volatilization, such as responding to the occurrence of abnormal odors.

Elaborate Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a heat-sensitive deodorizing fragrance whose volatilization amount changes depending on the temperature, in the air passage of an air conditioner. In addition to accommodating and arranging the deodorizing fragrance, a heating means is provided for heating the deodorizing and aromatic agent as required.

Effect: Therefore, by controlling the heating applied to the heating means, the amount of volatilization of the deodorizing/fragrance agent can be freely adjusted.
Depending on the temperature of the air blown out from the air conditioner 7?1. Appropriate deodorization and fragrance are carried out without excess or deficiency.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. That is, as shown in FIG. 2, the vehicle air conditioner #/ according to this embodiment includes a pro-a unit λ, a cooling unit 3. A heater unit G (in which a ventilation passage t is formed) is provided with a blower fan 6, an evaporator 7, and a heater core l in this order. has an inlet λa,
In addition, the heater unit Hiro has a 4-ta air outlet that communicates with the passenger compartment.
are each formed. Between the evaporator 7 and the heater core, as shown in FIG.
An aVC opening rotor is provided, and a deodorizing/fragrance device 10 is arranged and fixed in the air passage j so as to close the opening. As shown in FIG. 1, the deodorizing/fragrance bag ft10 has a housing /2 that is fixed to the bottom wall a by screws and has an open bottom.
A plurality of holes/cores are formed on the upper surface of the core. Attach the bottom end of the housing/2 to the bottom cover l by means of the bottle/7.
μ is pivotally supported.

A chamber is formed in the middle eastern part of the plantar operculum 114.

A hook/4'a that engages with the edge of the housing 12 is formed on the free side. A heat-sensitive deodorizing/fragrance agent/l that volatilizes upon heating is placed on the external upper surface of the chamber 15, and the deodorizing/fragrance agent/l is placed inside the chamber 15.
An electric heater 17, which is a ninth means for heating, is housed. The electric heater 17 is incorporated into the circuit shown in FIG. In other words, this circuit includes the motor IT that drives the proafan 6 and the evaporator 7.
An electromagnetic clutch /9 of a compressor that supplies refrigerant is connected in series, and the electromagnetic clutch 19 is connected to a battery, 2/, via an air conditioner switch 20''. for,
The timer and the electric heater 17 described above are connected in series, and nine circuits are arranged in parallel. The two nuclear timers have a function of closing the circuit for a preset time after the air conditioner switch 20 is turned on and supplying current from the battery 2/ to the electric heater 17.

In this embodiment having the above configuration, when the air conditioner switch 1o is turned on, the electromagnetic clutch is activated to connect the compressor (not shown) to the engine, and the supply of refrigerant to the evaporator 7 is started.

At the same time, the motor /l rotates the proa fan t, and air is introduced into the air passage from the suction port 2a. On the other hand, the timer n operates at the same time as the air conditioner switch 20 is turned on, and the electric heater /7 is turned on from the battery, 2/.
Lura generates heat. The deodorizing/fragrance agent 16 placed on the upper surface of the outside of the chamber/J is heated and sufficiently volatilized by this heating. Further, the volatilized chemical agent passes through the holes 2a, flows inward through the air passage, mixes with the air introduced by the blower fan B, and is blown into the vehicle interior through the air outlet μa. To be careful, before the evaporator 7 is sufficiently cooled, an appropriate amount of chemicals evaporated from the deodorizing/fragrance agent/A is mixed into the odor #1 caused by various bacteria adhering to the evaporator 7. Effectively deodorizes. When the evaporator 7 is cooled down to a certain temperature change, the odor is drastically reduced to the point where it cannot be detected. On the other hand, timer n
When the set time has elapsed, the circuit is opened and the electric heater 17 stops generating heat. Then, the temperature of the evaporator 7 becomes low and conditioned air free of foreign odor is obtained. At times n and e, the deodorizing/fragrance agent/l stops volatilizing. Therefore, it is possible to prevent unnecessarily volatilized deodorizing/fragrance from filling the vehicle interior and causing discomfort.
It is possible to suppress the waste of 6. As shown by the broken line in FIG. 1, the bottom cover can be opened by separating it from the edge of the hook part/9ai housing 12! ! , P-used deodorizing/air freshener with simple operation/
6 can be replaced with a new one.

DETAILED DESCRIPTION OF THE INVENTION As a reminder, the present invention accommodates and arranges a heat-sensitive deodorizing/fragrance agent in the air passage of an air conditioner, and heats the deodorizing/fragrance agent as necessary. Therefore, sufficient deodorization can be achieved by heating the deodorizing/fragrance agent only when an abnormal odor occurs, and when unnecessary, heating is completely stopped to prevent unnecessary volatilization of the deodorizing/fragrance agent. I can do it. This prevents the deodorizer/air freshener from volatilizing when unnecessary, filling the room and causing discomfort, and also enables the efficient use of the deodorizer/air freshener. be.
