[0002]

2. Description of the Related Art Conventionally, the air conditioner of the above-described example is provided with a heat exchanger which acts as an evaporator (evaporator) during cooling and acts as a condenser (condenser) during heating, and is provided in the housing. Due to the fact that the indoor air including dust, moisture, cigarette smoke, etc. is sucked and heat exchanged from the air suction part, the fin portion of the complicated shape of this heat exchanger and the fan blade of the fan as a blowing means are easily contaminated, In addition, germs, mold, and the like are generated. If the air-conditioning operation is performed in such a state, there is a problem that indoor hygiene is impaired and the indoor environment is deteriorated due to generation of an unusual odor.

In order to solve such a problem, the present applicant has proposed a functional agent discharge means such as a nozzle upstream of the blowing means in a ceiling embedded type air conditioner in which a heat exchanger is arranged downstream of the blowing means. Is disposed, and washing is performed from this discharging means.
The inventor has already invented an auxiliary device for an air conditioner configured to discharge at least one of a fragrance, a bacteriostatic, a deodorant, and a fungicide as a single functional agent or a composite functional agent.

According to this auxiliary device, the cleaning blade, the fragrance effect, and the antibacterial effect are provided on both the fan blade of the blower and the fin having a complicated shape of the heat exchanger corresponding to the functional agent discharged from the discharger. Although there is an advantage that a deodorizing effect or a fungicidal effect can be obtained, a functional agent, particularly a liquid cleaning agent or a foaming cleaning agent, is supplied to the heat exchanger through the blowing means only by the wind force of the blowing means. Since a sufficient spraying force cannot be obtained, there has been a problem that a sufficient functional effect by the functional agent cannot be secured.

[0005]

SUMMARY OF THE INVENTION According to the present invention, at least one discharge means is provided near the upstream of the heat exchanger, and the functional agent is discharged directly from the discharge means to the heat exchanger. The functional agent can be sprayed directly on the heat exchanger regardless of whether the blowing means is stopped or driven, and the functional agent has sufficient functional effects (cleaning effect, aroma effect, antibacterial effect, deodorant effect) The purpose of the present invention is to provide an auxiliary device for an air conditioner which can ensure the effect or the anti-mold effect).

[0006]

According to the present invention, there is provided an air conditioner in which a heat exchanger is arranged downstream of a blower means, at least one of which is located near an upstream of the heat exchanger. A functional agent discharging means is provided and configured to directly discharge at least one of a single functional agent or a composite functional agent among cleaning, aroma, antibacterial, deodorant, or antifungal from the functional agent discharging means to the heat exchanger. It was done.

The above-mentioned air conditioner may be any type of an air conditioner of a ceiling embedded type, a ceiling hanging type, a wall hanging type, a stationary type, and a window type. The functional agent discharging means having the above configuration can be constituted by one or a plurality of nozzles or the like.

[0008] With the above configuration, whether the blower is stopped (that is, the air conditioner is stopped) or is driven,

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawings show an auxiliary device for an air conditioner. First, the configuration of the air conditioner will be described with reference to FIGS. 1 and 2.
Has an air inlet 13 on one side of the housing 12 and an air outlet 14 on the other side of the housing 12, respectively.

The air conditioner 11 is buried inside a ceiling 15 and is located on the outer side (downstream side) of the air inlet 13 (air inlet).
An air outlet 14 (air blowing portion) is formed at the outer periphery of a centrifugal fan 17 driven by a motor 16, and a heat exchanger 18 formed in an annular or square shape is installed on the outer peripheral side (downstream side) of the fan 17. ing.

The heat exchanger 18 is connected to a refrigeration cycle, and functions as an evaporator (evaporator) during cooling, and as a condenser (condenser) during heating.

A plurality of nozzles 19 are provided near the upstream of the heat exchanger 18. In this embodiment, the heat exchangers 18 are arranged in a rectangular frame as shown in FIG.
A total of four nozzles 19 are arranged near the upstream of the rectangular frame-shaped corner portion of the heat exchanger 18, and a jet port 22 (see FIG.
2), the functional agent is ejected obliquely outward as shown by a dotted arrow in FIG. 2, but the ejecting direction is not limited to the illustrated direction.

The nozzle 19 is formed so as to have a length substantially equal to the total height of the heat exchanger 18, but the nozzle 19 includes a portion just upstream of the corner portion and exchanges heat with the downstream portion of the fan 17. The fan 17 may be additionally provided at another position between the upstream and the fan 18, or may be provided at an upstream intermediate portion of the fan 17.

The lower part 12 of the housing 12
a or a receiving member 20 (receiving means) attached to the lower surface of the ceiling 15 and an appropriate piping member 2 such as a rubber hose or a resin tube.
1 (functional agent supply path).

The specific structure of the nozzle 19 is as shown in FIG. That is, as shown in FIG. 3, the nozzle 19 is a relatively elongated tube having a closed end 19a, for example, a cylindrical shape, and a portion facing the front surface (inner surface) of the heat exchanger 18 is shown in FIGS. A plurality of ejection ports 22 for ejecting the functional agent fluid a in the direction of the dotted arrow 3 are formed.

A flange 1 is provided on the base end side of the nozzle 19.
9b and a joint 19c, the above-mentioned flange 19b is joined to the housing lower part 12a by appropriate means (adhesion, clipping, bolt-up, etc.), and the above-mentioned joint 19c serves as a functional agent supply path. Piping member 21
Is desirably fitted and fixed by effectively utilizing its elastic fastening force (elastic restoring force). It is needless to say that the functional agent supply path may be constituted by a metal pipe instead of a flexible pipe member such as a rubber hose or a resin tube.

As shown in FIG. 3, the receiving member 20 has a flange portion 25 integrally formed on a main plate 23 located in the middle via a ring-shaped spacer 24, and a guide portion 26 provided at a central portion of the main plate 23. The functional agent passage 2 between the outer peripheral portion of the spacer 24 and the joint portion 27 protruding outward from a part of the outer periphery of the spacer 24.
8 is formed.

The above-mentioned guide portion 26 is for inserting the nozzle N of a filling container (functional agent container such as a handy type filled with gas) as a source of the functional agent at the time of supplying the functional agent. Is formed with a tapered portion 29 having a larger diameter on the outer side (lower side in the figure) and a smaller diameter on the inner side (upper side in the figure). Is formed with an annular step portion 30 for preventing the nozzle N from being excessively inserted. The holder 3 integrally formed on the main plate 23 on the side opposite to the spacer (the lower side in the figure).
A lid member (not shown) may be detachably supported on 1.

The joint portion 27 of the receiving member 20 is connected to the piping member 21 such as the rubber hose.
The base side of the receiving member 20 is fitted and fixed by effectively utilizing its elastic tightening force (elastic restoring force), and the functional agent passage 28 of the receiving member 20 communicates with each of the nozzles 19 via the piping member 21. .

The functional agent fluid a may be a liquid cleaning agent or a foamed cleaning solution (water, phosphoric acid, softanol 7).
0, propylene glycol monomethyl ether MFG
Etc.), washing water, fragrance, medicine, deodorant, deodorant, deodorant, disinfectant, antibacterial agent, antibacterial agent, fungicide, fungicide alone or in combination (Complex) can be used. Each element 19, 20, 2 shown in FIG.
1 is handled as a kit, and the air conditioner 11
The above elements 19, 20, and 21 may be added to the above.

Further, the above-mentioned receiving member 20 is attached to a surface on the indoor side of a vertical wall partitioning the room, and the receiving member 20 is provided at a position close to the hand so that the operation of supplying the functional agent can be easily performed. The above-mentioned nozzle 19 may be communicated with a functional agent supply path (rubber hose, resin tube, metal pipe, or the like). In FIG. 2, b indicates the rotation direction of the fan, and c indicates the flow direction of the wind generated by the fan 17.

The operation of the thus configured auxiliary device for an air conditioner will be described. When washing the heat exchanger 18, the nozzle N of the filling container is inserted into the functional agent passage 28 while being guided by the tapered portion 29 of the guide portion 26 of the receiving member 20 shown in FIG. When the cleaning fluid is supplied under pressure, the cleaning fluid is supplied to the pipe member 21 through the functional agent passage 28 and flows into the nozzle 19 from the tip end thereof. Therefore, the fins (not shown) having a complicated shape of the heat exchanger 18 and the like can be satisfactorily washed.

When the fan 17 is driven while the cleaning fluid is being ejected from the injection port 22, the cleaning fluid is generated by the blasting action of the fan 17 and further inside the heat exchanger 18 such as fins having a complicated shape. And the cleaning effect can be further improved.

The order of use of the functional agent fluid a may be such that a foaming detergent, a disinfectant or an antibacterial agent is used in this order, and a foaming detergent, washing water and a drug are used in this order. Alternatively, a non-foamed liquid detergent and an antibacterial agent may be used in this order. Further, after the cleaning treatment, air, warm air, hot air or cold air may be applied from the base end of the pipe member 21 described above. For example, the heat exchanger 18 may be supplied to perform a drying process.

In particular, if the functional agent fluid a ejected from the nozzle 19 is set as a foam-like cleaning fluid, the foam-like cleaning fluid ejected from the nozzle 19 even if the size of the nozzle 19 is relatively short. Is spread over the entire area of the heat exchanger 18 due to the properties of the foamed fluid, and the foamed cleaning fluid has an effect that the entire heat exchanger 18 can be efficiently cleaned even to the inner part thereof, For this reason, the size of the nozzle 19 is reduced and the nozzle 19 with respect to the air conditioner 11 is reduced.
There is an effect that the improvement of the attachment property can be achieved.

In place of the above-described cleaning of the heat exchanger 18, a corresponding functional agent is applied to the heat exchanger 18 for sterilization, sterilization, antibacterial, sterilization, deodorization, deodorization, deodorization, or mold prevention. The nozzle N of the filled filling container may be inserted into a predetermined portion of the receiving member 20, and the corresponding functional agent may be pressure-fed. In order to release the fragrance into the room by using the conditioned air, the filling container in which the fragrance is sealed may be similarly operated.

In particular, when the fan 17 is rotated,
It is possible to more effectively wash, sterilize, deodorize or mold-proof substantially the entire heat exchanger 18 with various functional agents ejected from the ejection port 22 of the nozzle 19 by the wind force. When used, the fragrance can be released into the room.

As described above, the accessory for the air conditioner of the embodiment shown in FIGS. 1 to 3 is a blower (see fan 17).
In the air conditioner 11 in which the heat exchanger 18 is disposed downstream of the air conditioner, at least one
Two functional agent discharging means (see nozzle 19) are provided, and at least one of a single functional agent or a composite functional agent selected from the group consisting of washing, aroma, antibacterial, deodorant, and antifungal is directly subjected to the heat exchange from the functional agent discharging means. It is configured to discharge to the vessel 18.

With this configuration, the functional agent discharged from the discharge means (see the nozzle 19) is directly heated by the air blower (see the fan 17) regardless of whether the air conditioner is stopped or driven. It can be sprayed on the exchanger 18, and as a result, a sufficient functional effect (see washing effect, aroma effect, antibacterial effect, deodorizing effect or antifungal effect) by the functional agent can be secured.

When the functional agent is set to a liquid cleaning agent or a foaming cleaning agent, the discharging means (nozzle 19) is used.
) Can be sprayed directly onto the heat exchanger 18 to efficiently clean the fin portions of the heat exchanger 18.

Further, as shown in the embodiment, a smaller number of the functional agent supply sections (the bases of the functional agent passages 28 in one receiving member 20) are provided for the plurality of discharge means (see the four nozzles 19). When the functional agent is supplied from the end portion), the functional agent can be discharged from all discharging means, so that the operability of supplying the functional agent can be improved.

In addition, when a nozzle (not shown) directed toward the fan blade side of the fan 17 is additionally provided in the nozzle 19, when a cleaning agent is used as a functional agent, the heat exchanger 18 The cleaning with the fan blade can be performed at the same time.

Is attached to the inner surface of the top deck portion 12b of the housing 12, and the inlet portion 34 is led upward (ie, outward) from the top deck portion 12b of the housing 12. Even with such a configuration, the same operation and effect as those of the embodiment of FIG. 6 are obtained. Therefore, in FIG. 7, the same parts as those of FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 8 shows still another embodiment of the auxiliary device for the air conditioner. In addition to the configuration shown in FIG. 2, a portion between the downstream portion of the fan 17 and the upstream portion of the heat exchanger 18 is provided.
