Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing air conditioner for deodorizing and cooling the air in a room, which is installed in, for example, a toilet room.

[0002]

2. Description of the Related Art Conventionally, the air conditioning of a toilet has been performed by an air conditioner installed on the ceiling or wall of the toilet. In general, the size of the toilet room is small and it is uneconomical to install an ordinary air conditioner. Therefore, central heating is often used to simultaneously air-condition other rooms. The offensive odor of ammonia, methylcaptan, etc. generated in the toilet room is removed or masked by placing a commercially available deodorant, deodorant or fragrance.

For example, in the scent supply device with a deodorizing function disclosed in Japanese Patent Application Laid-Open No. 4-278129, by operating a sirocco fan, the outside air is taken in through the intake port to deodorize the air and then add the scent to the air. It is designed to be discharged from the exhaust port.

[0004]

However, in the above-mentioned deodorizing function-equipped scent supply device, since the fragrance is always aroma when the deodorizing function is activated, the fragrance is consumed quickly, and the fragrance is consumed more than necessary. It was uneconomical because it could be released indoors.

Therefore, it is a technical object of the present invention to provide an economical deodorizing air conditioner which does not release the fragrance more than necessary and can keep the effect of the fragrance for a long time.

[0006]

[Constitution of the invention]

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 is directed to an apparatus main body, and a duct which is disposed in the apparatus main body and has an intake port and an exhaust port at an end thereof.
A deodorizing air conditioner equipped with a fan and a deodorizing means arranged in the duct, and an air conditioning means and an aroma means arranged downstream of the deodorizing means in the duct, wherein the aroma agent is injected into the aroma agent. The deodorizing air conditioner detects a user by having a fragrance case having an opening at the upper end, a lid that shields the opening, and a lid drive unit that opens and closes the lid to diffuse the fragrance. The deodorizing air conditioner is characterized by comprising: a person detecting means for performing the operation and a control means for activating the lid driving section when receiving a signal from the person detecting means.

According to a second aspect of the present invention, in the first aspect of the invention, when the control means receives a signal from the human detection means, the lid drive section is intermittently operated, and at the same time, the lid section is operated. The opening time is long immediately after receiving a signal, 2
It is a deodorizing air conditioner that controls the lid driving unit so that it becomes shorter after the first time.

[0009]

According to the first aspect of the invention, air is sucked into the duct from the intake port by the action of the fan,
After being deodorized by the deodorizing means, it is fragranced by the fragrance means and discharged from the exhaust port of the duct. Fragrance means
By opening the lid of the fragrance case into which the fragrance is injected, the fragrance is diffused into the duct to perfume the outside air, but the fragrance case lid detects the user by the human detection means. It is opened by the lid drive part when it is done.

Therefore, the fragrance is consumed only when the user is in the room, and the fragrance is consumed only when necessary. Therefore, the aroma action lasts for a long time without waste. Further, since the fragrance does not diffuse more than necessary, the fragrance of the fragrance does not become too strong.

According to the second aspect of the invention, the fragrance time of the fragrance is set to be shorter in the second operation time than in the first operation time. That is, once the room is once scented by the first operation, this scent does not completely disappear from the room, so the second operation can be scented in the same manner even if it is shorter than the first operation. By saving the aroma time, the aroma action can be maintained for a long time, and the aroma agent can be used more economically.

Above the first thermoelectric conversion surfaces 41a, 42a of the Peltier elements 41, 42, the first heat exchange chamber 43 and the second heat exchange chamber 44 formed by the frame member 45 are located, and the frame members are formed. A water guide bracket 46 is fixed by screws 47 above the 45 and the first and second heat exchange chambers 43 and 44. The water guide bracket 46 includes four water channels 46a to 4a.
6d is formed. The water channel 46a is the first heat exchange chamber 43.
A plurality of small holes 51 (FIG. 8) are formed facing the first heat exchange chamber 43 to supply tap water to the. Tap water is discharged perpendicularly to the Peltier element 41 through the hole 51, and heat is efficiently exchanged with the first heat exchange surface 41a. Further, a pipe 48a, a pump 49, and a water supply pipe 50 are sequentially connected to the water passage 46a, and the tap water supplied to the water supply pipe 50 is guided by the pump 49 to the pipe 48a and the water passage 46a.

The water passage 46b is for draining the tap water supplied to the first heat exchange chamber 43.
Is formed with a single hole 52. Waterway 46b
One end of the pipe 48b is disposed in the
The other end of b is disposed in the water channel 46c. In this way, the tap water that has already undergone heat exchange in the first heat exchange chamber 43 is sent to the second heat exchange chamber 44 not directly from the water source but through the water passage 46c and is reused.

The water passage 46c is formed with a plurality of small holes 53 similar to the water passage 46a, and the water jetted from the holes 53 is jetted vertically to the Peltier element 42 to exchange heat with the first heat exchange surface 42a.

The fin 61 is integrated on the upper end surface, and is in thermal contact with the second heat exchange surfaces 41b and 42b on the upper surface. A plurality of partition plates 65 (Fig. 9) are formed in the duct 3 between the sirocco fan 31 and the fins 61. With this partition plate 65, the atmosphere sent from the sirocco fan 31 is not biased to one side of the fin 61,
It is sent evenly throughout. Therefore, the heat of the fins 61 and the atmosphere are efficiently exchanged.

Next, the operation panel 70 will be described.
As shown in FIG. 6, the operation panel 70 includes the front grill 2
It is disposed between the intake port 3a of a and the exhaust port 3b.
The operation panel 70 includes an operation changeover switch 71, an air conditioning switch 72, an emergency switch 73, and fragrance switches 74 and 75.
Switches are provided. Operation changeover switch 71
Is a switch for switching between continuous operation and intermittent operation of the sirocco fan 31. The intermittent operation indicates a state in which the sirocco fan 31 operates only when the human detection sensor 77 detects that the user has entered the toilet room. As the human detection sensor 77, an infrared sensor, an ultrasonic sensor, a pyroelectric sensor, or the like similar to the conventional one can be used, and therefore a detailed description thereof will be omitted. Air conditioning switch 72
Is a switch for turning on / off the energization to the Peltier elements 41, 42 and switching the energization direction, and switches the blown air discharged from the exhaust port 3b between hot air, cold air and room temperature air each time it is pressed. It has become. The emergency switch 73 is a switch that is pressed when feeling uncomfortable in the toilet room. When the emergency switch 73 is pressed, a chime sounds from a speaker (not shown) arranged outside the toilet room, and an emergency is given to the family. It is supposed to inform you of the situation. Further, the fragrance switches 74 and 75 are for selecting the scents of the two kinds of fragrance cases 22 arranged in the apparatus main body 2. When the fragrance switch 74 is pressed, one solenoid 25 turns the fragrance switch 75 on. When pressed, the other solenoid 25 is energized, and the opening 23 of either one of the fragrance cases 22 is opened. The signals output from these switches are sent to the control unit 79 (FIG. 11), and the control unit 79 outputs an operation command to the motor 32 and the like. Reference numeral 76 represents a digital timepiece, and the time can be adjusted by the timepiece operation units 76a and 76b.

Next, the operation of this embodiment will be described.
When the continuous operation is selected by the operation changeover switch 71, the motor 32 and the pump 49 continuously operate to suck the air in the toilet room. The sucked air is
First, after the filter 11 removes dust and the like, the first carrier 12 removes the sulfur-based odor due to the action of ginger ginger and the second carrier 13 removes the amine-based odor due to the action of psyllium. In this embodiment, the second carrier 13 to which the components extracted from plantain are adsorbed is installed on the downstream side. Psyllium has the property of adsorbing not only amine-based but also sulfur-based odors, so the geno-shoko adsorbs the rest of the slight sulfur-based odor that could not be completely absorbed by geno-shoko, and completely removes the sulfur-based odor. Is possible.

The deodorized air is given a scent of either the fragrance case 21a or the fragrance case 21b by the fragrance section 20 and sent to the air conditioning section 40. The type of aroma depends on which of the aroma switches 74 and 75 is selected. For example, when the fragrance switch 74 is selected, the solenoid 25a is energized and the fragrance case 2
2a is opened. On the contrary, when the fragrance switch 75 is selected, the solenoid 25b is energized to open the fragrance case 22b. When it is desired to make the fragrance-free, the energization of the solenoid can be stopped by pressing the selected switch, and the fragrance cases 22a and 22b can be covered.

In the air conditioner 40, the Peltier elements 41, 42 are energized, and one of the first heat exchange surfaces 41a, 42a and the second heat exchange surfaces 41b, 42b acts as a heat absorbing surface and the other acts as a heat generating surface. . Here, the second heat exchange surfaces 41b, 4
The case where 2b acts as a heat absorption surface and the air is cooled will be described. In this case, the first heat exchange surfaces 41a, 42a
Generates heat and is cooled by tap water supplied by the pump 49. On the other hand, the fins 59 are cooled by the endothermic action of the second heat exchange surfaces 41b and 42b, and further, heat exchange is performed with the air flow passing through the duct 3, whereby the air flow is cooled. In this way, the airflow discharged from the exhaust port 3b is discharged as a comfortable cool air in the summer.

Next, a case where the intermittent operation is selected by the operation changeover switch 71 will be described. If intermittent operation is selected, the motor 32 and solenoid 2
5a, 25b, Peltier elements 41, 42 and pump 49
(Hereinafter, the motor 32 to the pump 49 are also referred to as drive means.) The power supply is intermittent. First, when the human detection sensor 77 detects a user in the toilet room, the control unit 79 operates the drive means for a predetermined time to perform deodorization, aroma, and air conditioning as in continuous operation. In the case of intermittent operation, the drive means operates for a predetermined time, then stops for a while, and then restarts. However, the second operation time is set shorter than the first operation time. The operation time after the third time is the same as the operation time after the second time. In this way, the process continues until the human detection sensor 77 no longer detects the user.

When the intermittent operation is selected, the driving means does not operate when the user is not in the room, so that there is no waste of electric power and fragrance, and economical operation can be performed. Also, once the interior of the room is fragranted by the first operation of the intermittent operation, this fragrance does not completely disappear from the room, so the second operation can be fragrant similarly even if it is shorter than the first operation. Therefore, the aroma action can be maintained for a long time by saving the aroma time.
