Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device for deodorizing a odor generated in a toilet by sucking and collecting the odor together with an air flow.

[0002]

2. Description of the Related Art Conventionally, a deodorizing apparatus of this type is a well-known deodorizing means, as shown in FIG. 8, in a gap 4 between a toilet bowl 1 and a toilet seat 3 having a toilet lid 2, and a suction port 5 is provided at a tip thereof. A suction duct 6 having a deodorant made of activated carbon or the like and a deodorizer 8 having a blower for suction or the like, or installed in a toilet installation space 9 to remove the odor in the toilet 7 from the toilet 7 There is a type in which the odor diffused in the toilet installation space 9 is decomposed and deodorized with a catalyst such as a platinum catalyst. Arrows in the figure indicate the flow of the odor. Recently, although not shown in FIG. 8, a deodorizing circuit composed of a deodorant and a blower incorporated in the toilet seat-integrated warm water flush toilet seat sucks air from the rear of the toilet 1 and discharges it into the toilet installation space 9. I have. In each of the above three examples, the odor is released into the toilet space 9 after the odor is suctioned and processed.
Japanese Patent Application Laid-Open No. 03-228931 discloses that a suction port and an outlet of a deodorizer body having an ozone generator are provided at a position facing the inside of the toilet bowl, ozone is generated from the outlet to decompose odor components, and the ozone blown out. A circulation air passage is formed in order to dilute the concentration.

[0003]

However, in the case of the conventional deodorizer 8 having only the suction port 5, the main body of the deodorizer 8 and the suction duct 6 are integrated. Inhalation was not possible, and it was 0.
Only a part of the odor is collected because it can be sucked only with the air volume of about 1 m ³ / min or less. Further, once the odor diffuses into the toilet installation space 9, deodorization is started after the toilet user senses the smell, so that the user does not feel the deodorizing effect as much as the ventilation fan. On the other hand, in the case of a collecting means having a suction port and an air outlet and circulating, since a sufficient blowing flow rate cannot be obtained in terms of thermal sensation, the effect of circulating and collecting is not sufficiently drawn out, and ozone is also generated. The effect on the human body by blowing into the toilet may be considered. Furthermore, none of the above deodorizers has a problem that a sufficiently satisfactory deodorizing effect has not been obtained for nitrogen-based odor components represented by ammonia and sulfur-based odor components represented by hydrogen sulfide.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a collecting block having a suction part and a sending part which opens in a toilet provided with a toilet seat installed in a toilet installation space; A blower, a detachable heater, an adsorbent, and a self-heating type decomposition catalyst are arranged in a main body air passage having both ends of an inlet and an outlet connected through a block and a duct. Controlling the operation of the exothermic decomposition catalyst,
It has a deodorizing block having a control circuit with room temperature detecting means and a human body detecting means. When a human body is detected by the human body detecting means, a signal from the room temperature detecting means supplies power to the blower or the blower and to the self-heating type decomposition catalyst. The air in the toilet is recirculated from the suction section through the deodorizing block and back into the toilet from the sending section, and generates heat at a low temperature level that does not cause decomposition of the self-heating type decomposition catalyst constituting the deodorizing block. The relationship between the signal from the room temperature detecting means, the amount of heat generated by the self-heating type decomposition catalyst, the operating voltage, and the output of the blower is obtained in advance in the control circuit from the perspective of human thermal sensation, and the control sequence is used to deodorize. Because of the operation, the limit value of the thermal sensation can be set to the suction and delivery air volume higher than that of the conventional deodorizer, and as a result, a recirculation flow that does not emit odor out of the toilet can be formed on the toilet and continuous With the air flow odor components can improve the collection efficiency of the odor because it can lead to the adsorbent, it is possible to greatly improve the performance for deodorization.

BEST MODE FOR CARRYING OUT THE INVENTION
A collection block having a suction unit and a delivery unit that opens into a toilet provided with a toilet seat installed in a toilet installation space, and a body having both ends of a suction port and an air outlet connected via a collection block and a duct. A blower, a detachable heater, an adsorbent, and a self-heating type decomposition catalyst are disposed in the air passage, and the operation of the blower, the detachment heater, and the self-heating type decomposition catalyst is controlled, and a room temperature detecting unit and a human body detecting unit are provided. A deodorizing block having a control circuit, and when the human body is detected by the human body detecting means, a signal from the room temperature detecting means is supplied to the blower or the blower in addition to the self-heating type decomposition catalyst, and the air in the toilet is discharged from the suction part. The toilet is returned to the toilet from the delivery section through the deodorizing block, and when a toilet user enters the toilet installation space, the human body detecting means detects it and at the same time the room temperature at that time is detected by the room temperature detecting means. The deodorizing operation is started by the preset heat output of the blower and the self-heating type decomposition catalyst from the room temperature detection signal, and the deodorization has already been performed when the user sat on the toilet seat, so the odor component at the time of defecation Is deodorized by the reflux stream without diffusion. Explaining the flow of air that collects odor components at that time, the space inside the toilet will be blocked by the buttocks of the user except for the front part and the gap between the toilet and the toilet seat during defecation. The airtight space is formed to some extent, and the odor generated inside the toilet is sucked from the only suction part provided near the generation location. In addition, the air is depressed through the deodorizing block and is pushed into the suction unit by the deodorized air flow from the delivery unit provided on the opposite side. On the other hand, the adsorbent begins to desorb at high temperatures, but the flow of the sucked air is small because the air in the toilet installation space is also drawn in from the front part of the toilet, and the heat generated by the self-heating type decomposition catalyst is low. Is not a problem because the self-heating type decomposition catalyst is disposed at a position downstream of the adsorbent. As a result, it is possible to realize deodorization with almost no odor even when the user completes defecation and stands up from the toilet seat. In addition, since the flow of air that satisfies the thermal sensation can be recirculated from the delivery unit into the toilet bowl by using the heat generation effect of the self-heating type decomposition catalyst without fear of desorption, the temperature is set from the thermal sensation. The limit value of the conventional suction air volume can be raised, and the trapping ability can be further improved. Further, the above-described operation provides an effect of replacing the heating toilet seat, and the self-heating type decomposition catalyst is operated only during use, so that it is not necessary to constantly supply power, so that an energy saving effect can be obtained.

According to a second aspect of the present invention, the collecting block is disposed in the gap between the toilet and the toilet seat and is detachable. The gap, which is a major cause of odor leakage during defecation, is closed. The airtightness of the toilet space is improved, and the collecting capacity is further improved even with the same air volume. In addition, it can be attached to any type of toilet regardless of whether a toilet seat or a heated toilet seat is installed, and because it is detachable, a single deodorizing block can be used for toilet installation space and other room deodorizing applications. The toilet bowl can be cleaned without any trouble by removing the odor collection block each time, and the collection block itself can be easily maintained.

According to a third aspect of the present invention, the delivery section has a plurality of collecting blocks, and the air returned from a plurality of locations around the toilet space is sent to the center of the toilet, so that the inside of the toilet is further increased. The odor can be sent to the deodorizing block without escaping outside the toilet, and the same trapping effect can be obtained with a small amount of suction air.

According to the fourth aspect of the present invention, the flow to be delivered has a delivery section directed toward the suction section, and the odor generated by the flow from a plurality of locations around the toilet bowl toward the suction section is reduced. It is easily guided to the suction section.

According to a fifth aspect of the present invention, the leak preventing means is provided in the gap where the collecting block is not provided, so that the airtightness of the toilet bowl space can be increased, and even at the same reflux air flow rate. The trapping performance is improved.

According to a sixth aspect of the present invention, when the signal from the human body detecting means is released, the power supply to the self-heating type decomposition catalyst is stopped, and the rotation speed of the blower is increased at a higher speed than the normal operation rotation speed for a predetermined time. It has a control circuit for operation.When the user rises from the toilet seat, the space inside the toilet is opened, and at the same time power is supplied to the self-heating type decomposition catalyst, it is stopped and only the blower is rotated at high speed. It is possible to prevent the residual odor from diffusing from the inside of the toilet to the toilet installation space.

According to a seventh aspect of the present invention, an opening having a suction thermistor and an opening / closing means is provided on the suction side of the collecting block or the deodorizing block, and when the value of the suction thermistor exceeds a set suction temperature or when a human body is detected. When the signal from the means is released, the opening / closing means is opened and the air in the toilet installation space is simultaneously sucked from the opening, and especially in winter when the room temperature is low, warm air is sent into the toilet and the odor component from the suction part The air flow sucked together mixes with the air in the toilet installation space entering from the front of the toilet or from the gap, but the temperature tends to rise, and the components adsorbed so far from the adsorbent may be desorbed in reverse . However, by setting the suction temperature of the suction thermistor, it is possible to operate the opening / closing means to mix more cool air into the intake side from the opening communicating with the toilet installation space, thereby preventing deodorization of odor components from the adsorbent. . In addition, even after the user leaves the toilet installation space, the toilet installation space is deodorized at the same time as the inside of the toilet, so that the odor that has diffused partially into the toilet installation space can be removed, and immediately after the next user entered the room In this case, it can be used comfortably without odor.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows a configuration diagram and an installation state of a toilet bowl deodorizing apparatus according to Embodiment 1 of the present invention. The toilet deodorizing device is mainly composed of two blocks. One is a collection block 10, which shows a state in which the toilet seat 12 is opened in FIG. 1 at a location that opens into the toilet bowl 11, and is provided with a suction unit 13 and a delivery unit 14 substantially opposite to the rear. On the other hand, another block, a deodorizing block 15, has a blower 19, a desorption heater 20, an adsorbent 21, and a self-heating type decomposition catalyst 22 sequentially in a main body air passage 18 having an inlet 16 and an outlet 17 at both ends. The adsorbent 21 and the self-heating type decomposition catalyst 22 are provided separately, and the inlet 16 and the outlet 17 are connected to the suction part 13 and the discharge part 14 of the collection block 10 by flexible ducts 23, respectively. Are in communication.

Although the blower is provided on the upstream side in FIG. 1, it may be provided on the downstream side. The deodorizing block 15 has a room temperature detecting means 25 such as a thermistor for detecting the room temperature of the toilet installation space 24 installed therein, and an infrared sensor or an ultrasonic sensor for detecting that a toilet user has entered the toilet installation space. Human body detection means 2 consisting of a seat switch, etc.
6 are installed, operate them and blowers 19
And a control circuit 27 for controlling the operation of the heater 20 for detaching and attaching, and the self-heating type decomposition catalyst 22. The deodorizing block 15 may be installed not only separately from the toilet 11 as shown, but also beside or behind the toilet. Also, if the collection block 10 is also a place that opens into the toilet 11, the toilet seat 1
The space around the toilet 11 or the space behind the toilet 11 is not limited to two. Next, the operation and operation will be described. When a user enters the toilet installation space 24, a room temperature signal at that time is sent from the human body detection unit 26 to the control circuit 27 from the room temperature detection unit 25 simultaneously with the entry signal from the human body detection unit 26, and the control circuit 27 presets the room temperature signal from the room temperature detection signal. The operation of the deodorizing block 15 is started by the operation output of the blower 19 and the self-heating type decomposition catalyst 22. For example, when the temperature is cold in winter, the flow from the sending unit 14 is a warm air of about 40 ° C., but in the hot summer, the air is not supplied to the self-heating type decomposition catalyst 22 but becomes only the blower 19.

Therefore, when the user sits on the toilet seat 12, the deodorizing operation has already started, and the odor tends to diffuse out of the toilet 11 through a part of the front of the toilet 11 and the gap 28 between the toilet 11 and the toilet seat 12. At the same time as the air is sucked in with the flow of air from the suction unit 13 provided in the vicinity of the generation location, the air is also pushed into the suction unit 13 by the recirculation flow from the sending unit 14 provided on the opposite side. Since the limit value of the suction air volume set from the thermal sensation can be increased by returning the flow of air that satisfies the thermal sensation to the toilet 11 from the delivery unit 14 by the heat generation effect of the self-heating type decomposition catalyst 22. , The amount of suction and delivery air can be increased, and the odor component is not diffused out of the toilet
3 to the deodorizing block 15. The white arrows in the figure indicate the flow of the odor in the toilet bowl that has been sucked and the flow that is blown out after the deodorization.

The deodorizing function of the deodorizing block 15 is as follows. First, an odor component is adsorbed by an adsorbent 21 made of zeolite, activated carbon, or the like, and the heater 20 is energized during a time when the toilet is not used before reaching the adsorption capacity. To desorb the odor component from the adsorbent 21, and at the same time, energize the self-heating type decomposition catalyst 22 composed of an oxidation catalyst in its original use, hold it at a high temperature and pass the desorbed odor component to decompose it into carbon dioxide gas and water. The deodorizing block 15 is sent semi-permanently without being influenced by the adsorption capacity.

(Embodiment 2) FIG. 2 is an external view of a toilet bowl deodorizing apparatus according to Embodiment 2 of the present invention. The difference from the first embodiment is that the collection block 10 is provided in the gap 28 between the toilet 11 and the toilet seat 12 so that the collection block 10 can be detachably moved.

The parts having the same reference numerals as in the first embodiment have the same structure, and a description thereof will be omitted. Next, the operation and action will be described. The gap 28, which is a major cause of odor leaking into the toilet installation space 24 during defecation, is partially blocked by the collection block 10, and the airtightness in the toilet 11 is improved. The trapping ability is improved by this. In addition, it can be attached to any type of toilet 11 regardless of whether a washing toilet seat or a heating toilet seat is attached, and because it is detachable, the deodorizing block 15 alone can be used for toilet installation space 24 and other room deodorizing applications. Further, if the odor collection block 10 is removed, the toilet 11 can be cleaned without any trouble, and the collection block 10 itself can be easily maintained.

(Embodiment 3) FIG. 3 is an installation state diagram of a toilet deodorizing apparatus according to Embodiment 3 of the present invention.

The difference from the first or second embodiment is that another sending section 29 is provided next to the suction section 13 of the collecting block 10 separately from the sending section 14, and a total of two sending sections are attached. Is a point.

Next, the operation and function will be described. Air flow is formed from the left and right sides of the toilet 11 to the center of the toilet, and the flow of air that is pushed from the opposing delivery unit 14 and goes out of the toilet 11 is suppressed, and the odor is reduced. It is led to the center side together with the components.

(Embodiment 4) FIG. 4 is a diagram showing the installation state of the main parts of a toilet bowl deodorizing apparatus according to Embodiment 4 of the present invention.

The third embodiment differs from the third embodiment in that a delivery section 30 is provided in which the flow to be blown is directed toward the suction section 13. By creating a flow toward the suction unit 13, the odor component is further easily guided to the suction unit 13 together with the flow of air.

(Embodiment 5) FIG. 5 is an external view of an installation of a toilet deodorizing apparatus according to Embodiment 5 of the present invention. The difference from the first to fourth embodiments is that a leak preventing unit 31 made of an elastic material such as rubber or resin is provided in the gap 28 where the collecting block 10 is not provided. It increases the hermeticity of the space. The installation is, for example, the toilet 11

The opening / closing means 33 is opened, and the air in the toilet installation space 24 is also sucked through the opening 34 at the same time.

[0029]

As described above, according to the first aspect of the present invention, the self-heating type decomposition catalyst is used as a heater in a temperature range in which the decomposition phenomenon does not start. The structure of the recirculation type collection block that can be output changes the relationship between the airflow and the thermal sensation to the buttocks and raises the limit of the previously set suction airflow. Improvement can be achieved. In addition, the odor generated in the toilet bowl is sucked from the suction section provided near the generation point and simultaneously pushed into the suction section from the delivery section provided on the opposite side, so that the effect can be further improved. Furthermore, since the odor is already deodorized when the user sits on the toilet seat from the signal of the human body detection means, the odor can be treated before being diffused out of the toilet, and as a result, the defecation is completed and the user stands up from the toilet seat. Deodorization with almost no odor even when raised can be realized. In winter, the effect of replacing the heating toilet seat can be obtained by blowing warm air, and the heater is operated only during use, so that constant power supply is not required and an energy saving effect can be obtained.

According to the second aspect of the present invention, when the collecting block is detachably attached to the gap between the toilet and the toilet seat, odor leaks out of the toilet during defecation. Part of the gap is closed, and the trapping effect can be further improved. Further, it can be attached to any type of toilet bowl, and the collecting block can be separated so that the deodorizing block alone can be used as a deodorizing device.

According to the third aspect of the present invention, when the flow returned from the plurality of delivery sections facing the space in the toilet is pushed into the center of the toilet, the odor in the toilet is released to the outside of the toilet. The same effect can be obtained with a small amount of suction air.

According to the fourth aspect of the present invention, when the delivery section for forming a flow toward the suction section is provided, the flow of the air containing the odor component can be more easily guided to the suction section. .

Further, according to the fifth aspect of the invention, when the leak preventing means is provided in the gap, the tightness of the toilet bowl space can be improved, and the collecting performance can be further improved.

According to the sixth aspect of the present invention, the blower is rotated at a high speed after the toilet is used, so that the residual odor can be prevented from diffusing from the toilet to the toilet installation space.

According to the present invention, when the suction temperature is determined and the air in the toilet space is taken in, it is possible to prevent the adsorbent from being desorbed at the time of deodorization. Also,
Since the deodorization of the toilet installation space is performed simultaneously with the inside of the toilet after the user leaves the toilet installation space, the toilet can be used comfortably without odor even if the next user enters the room immediately afterwards.
