Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an insecticide sprayer used indoors. The present invention particularly aims at exterminating harmful insects such as cockroaches, flies and mosquitoes in the interior of a restaurant (kitchen) and the like, and a fan for discharging an insecticide to the outside, and a shutter for closing an inlet and an outlet. The present invention relates to an insecticide sprayer in which at least the above-mentioned fan and shutter are operated for a predetermined time by manual operation or timer operation. In addition, in this specification, the term "indoor" is not limited to the term "indoor of a restaurant (kitchen)", and is used broadly to include the meaning of indoors such as general houses, buildings and sports facilities. There is.

[0002]

2. Description of the Related Art In general, pests such as cockroaches, flies and mosquitoes are active in the human living area, and most of them carry pathogens that have a harmful effect on the human body. There is a need for eradication. Particularly, in dealing with foods and drinks that have a great effect on the human body, pest control is an important issue in restaurants and food and drink stores such as cafeterias, coffee shops, and supermarkets.

In addition, the presence of harmful insects causes discomfort to customers due to lack of cleanliness of the store, and causes distrust of the safety and reliability of the products to be handled, resulting in a decrease in the ability to attract customers. Become. Therefore, the extermination of harmful insects is indispensable in terms of hygiene and business, and is routinely performed not only in food and drink stores but also in general households, business establishments, sports facilities such as indoor pools, and the like.

[0004] Conventionally, as a method for exterminating these harmful insects, a method has been used in which indoor insects that have been cut off from the outside air are filled with an insecticide for a predetermined period of time to collectively kill the harmful insects that are active indoors. There is. This method can spray the pesticide all over the room including the narrow gaps, and is effective for mass exterminating pests indoors.

However, this method has the following drawbacks. It takes a certain amount of time for the pesticide to spread all over the room. Considering the harmful effects of the insecticide on the human body, indoor entry is often restricted during spraying of the insecticide, and is restricted when the indoor is not used. Even after the indoor pests have been exterminated, the pests may re-occur and may invade from the outside, so continuous use with a certain time interval is required.

Conventionally, the above-mentioned drawbacks are solved by forcibly spraying the pesticide by operating the electric fan provided in the pesticide sprayer, and the operating time of the electric fan is set by a timer. By continuously spraying the insecticide at night when there are no humans in the room, the above drawbacks are solved.

[0007]

SUMMARY OF THE INVENTION The above-mentioned conventional indoor pesticide sprayer is designed to discharge the air taken in through the inlet by the operation of the electric fan from the air outlet together with the pesticide. In order to release the pesticide to the outside, the pesticide needs to be vaporized inside the sprayer so that the taken-in air and the pesticide mix.

Therefore, the insecticide used in this type of indoor insecticide sprayer has only to have a high vapor pressure and have the property of continuing to diffuse at room temperature, and is practically easy to handle and long-term. Often solid or liquid pesticides are used which are also compatible with the use of.

In the non-use mode of the conventional indoor pesticide sprayer, the intake port and the blow-out port are in the open state as in the use mode. The stored (vaporized) insecticide is released to the outside,
In particular, when the insecticide is odorless, there is a problem that a person indoors does not notice the release and is adversely affected.

Further, in the indoor insecticide sprayer equipped with the timer, only the continuous operation within the set time is automatically repeated every day, and it is possible to spray each insect pest suitable for the attribute of the insect pest. No consideration was given to setting the time, and the effect on use was not sufficient.

That is, since cockroaches may have resistance to insecticides due to frequent spraying of insecticides, for example, the indoor insecticide sprayer is activated only every other night at night (human non-activity time). We responded to pests such as flies and mosquitoes prefer bright places, and since there are many parts of the activity time that overlap with humans, we respond by intermittent operation for a short time in consideration of human safety. It was not supposed to set the time.

Further, when the cockroach is eradicated, even if an excessive amount of insecticide is sprayed for a long time due to a timer setting error or the like, the electric fan does not stop operating as long as the timer sets the time. Since the pesticide is released to the human body, not only the pesticide is wasted, but also the adverse effect on the human body due to the large amount of the concentrated pesticide sprayed is increased.

Therefore, an object of the present invention is to prevent the insecticide from being inadvertently released to the outside, to ensure the safety to the human body and to prevent the wasteful release of the insecticide, and to set the spraying time of the insecticide to various levels. It is possible to effectively spray an insecticide to various kinds of insect pests by adding a function to be set in association with the characteristics of the insect pest to an indoor insecticide sprayer.

[0014]

DISCLOSURE OF THE INVENTION According to the present invention, a shutter is provided at each of the inlet and the outlet of an insecticide sprayer for indoor use, and the shutter is closed when not in use, so that the insecticide is careless. It is designed so as not to be released to the outside, and the opening / closing operation of the shutter and the driving / stopping operation of the fan can be switched by a manual operation unit or a timer.

FIG. 1 is an explanatory view showing the basic structure when a timer is used, in which 1 is an insecticide sprayer for indoor use, 2 is an inlet, 3 is an outlet, 4 is an internal space, 5 is a fan. , 6 is a fan drive motor, 7 is a spraying operation control unit, 8 is a power switch, 9 is a main timer for setting the spraying operation start time t ₀ and the spraying operation end time t ₁ , and 10 is set by the main timer 8. Individual timers for resetting the spraying operation mode according to the characteristics of the pests to be exterminated within the time, 11, 12 shutters, 13 and 14 motors, and 15 insecticides, respectively.

A fan 5 and a fan driving motor 6 for taking in air from the inlet 2 and discharging it from the outlet 3 are provided in the internal space 4 communicating with the inlet 2 and the outlet 3. At the same time, an insecticide 15 that is easily vaporized and has a high vapor pressure is installed.

Further, the spraying operation control unit 7 has a main timer 9
The shutter opening / closing signal and the fan driving / stopping signal are generated based on the output signal of the individual timer 10 and the individual timer 10, and the opening / closing operation of the shutters 11 and 12 is performed by the former signal and the fan 5 is activated by the latter signal. It controls each rotation operation.

The processing procedure in the spraying operation control section 7 when this control is performed is shown in FIG. That is, it is determined whether or not the power switch 8 is turned on. If “YES”, the process proceeds to the next step, and if “NO”, this determination is repeated. Determine whether the main timer 9 is set,
If "YES", proceed to the next step, and if "NO", proceed to step. The spraying operation start time t _o set by the main timer 9
And the spraying operation end time t ₁ are stored in a memory (not shown). The spraying operation time zone determined by t _o and t ₁ is not limited to a single spraying operation time slot, and a plurality of spraying operation time slots may be set in one day. It is determined whether or not the individual timer 10 provided in association with the pest type is set, and if “YES”, the process proceeds to step, and if “NO”, the process proceeds to step. The fan driving signal and the shutter opening signal are output to put the indoor insecticide sprayer 1 into a continuous operation state. In addition,
In this case, the pesticide will be sprayed all day long, which may damage the health of people indoors.
Instead of this continuous operation state, an alarm for calling the setting operation of the main timer 9 may be issued. The continuous spraying operation between the spraying operation start time t _o and the spraying operation end time t ₁ , that is, the fan driving signal and the shutter opening signal are output at time t _o , and the fan stop signal and the shutter opening signal are output at time t _1. The operation of outputting a shutter closing signal is performed every day. Within the time set between the spraying operation start time t _o and the spraying operation end time t ₁ set previously, the spraying operation according to the setting contents of the individual timer 10, for example, the spraying operation every predetermined time T or every predetermined number of days is performed. Therefore, the fan drive / stop signal and the shutter open / close signal are output. With such a procedure, a plurality of operation modes of the indoor insecticide sprayer 1 are selectively set.

The timing of switching the operation of the fan 5 and the shutters 11 and 12 and the timing of the opening and closing operation of the shutter 11 and the shutter 12 do not have to be the same at the same time. , 12 may be provided individually (for example, a main timer for setting the operation of only the fan 5).

Further, as described above, a manual operation unit for switching the operation of the fan 5 and the shutters 11 and 12 at any time may be provided and used together with the main timer 9 or the like. The main timer 9 and the like may be omitted, and the operations of the fan 5 and the shutters 11 and 12 may be switched by this manual operation unit.

[0024]

Embodiments of the present invention will be described with reference to FIGS. FIG. 4 is a perspective view showing the overall appearance of the indoor pesticide sprayer 1 of the present invention.
The air outlets 3 are provided in the lower part of the front surface, and the operation panel 17 and the lid 16 are provided on the front surface side. By forming the key portion 16a on the lid 16, a highly safe indoor insecticide sprayer is constructed so that the insecticide inside cannot be easily taken out.

The operation panel 17 is configured as shown in FIG. 5, and is provided with various operation / display units as described below. The power switch 8 turns on when you press the upper part.
When C and DC are energized, pressing the lower part turns them off. A power lamp (not shown) that lights up when turned on
Built in.

When the manual operation switch 18 is pressed to be turned on, the pesticide sprayer is in an operating state, that is, the fan 5 is driven to open the shutters 11 and 12. In this state, three red fan lamps 19 alternately blink to indicate that they are operating.

A switch for manual operation (manual operation part)
The reference numeral 18 performs both the operation switching of the fan 5 and the operation switching of the shutters 11 and 12, but the operation unit for driving / stopping the fan 5 and the operation unit for opening / closing the shutters 11, 12 are provided. They may be divided (not shown) and operated individually. Further, as described above, the timer may be omitted and the operation switching may be performed exclusively by the manual operation switch 18.

Further, when the manual operation switch 18 is turned ON, the fan lamp 19 blinks in the previous operating state in preference to the setting state of the main timer 9 which will be described later. You can check whether the pesticide sprayer works properly.

Those who are not accustomed to operating the timer can operate the manual operation switch 18 without operating various timers.
The pesticide sprayer can be activated by using. In addition, when this manual operation switch 18 is pressed again, it is turned off and the insecticide sprayer is stopped,
Only in this stopped state can the timer operation described later be performed.

That is, the main timer 9 is a 24-hour timer for setting the daily spraying operation start time t ₀ and the daily spraying operation end time t _1, and the set button 2
0, 21, 22 and a current time display liquid crystal unit 9a, an operation start time display liquid crystal unit 9b, and an operation end time display liquid crystal unit 9c.

By pressing the set buttons 20, 21, 22 respectively, the display liquid crystal parts 9a, 9b, 9c are displayed.
In, the display of the time including AM and PM is changed, and when the required time is displayed, when the display is released, the display stops at this time. The same operation is performed for the minutes, but the display on each of the display liquid crystal parts 9b and 9c changes in units of 10 minutes.

The timer set confirmation switch 23 is a switch which is pressed when it is confirmed that the display contents of the respective display liquid crystal parts 9a, 9b, 9c are correct, and the setting contents of the main timer 9 are changed by this pressing operation. After confirmation, the timer lamp 24 lights up.

The timer set confirmation switch 23
When is pressed again, the main timer 9 returns to the state in which the time can be set. Therefore, the current time, the spraying operation start time t ₀ , and the spraying operation end time t ₁ are set by re-operating the set buttons 20, 21, 22. It can be reset if necessary.

The cockroach timer 25 is an individual timer for exterminating cockroaches. When it is turned on, a built-in lamp (not shown) is turned on, and the spraying operation start time t ₀ set by the main timer 9 to the spraying operation end time. The spraying operation up to t ₁ is performed every predetermined number of days, for example, every other day.

Further, when the cockroach timer 25 is ON, the spraying operation is automatically stopped after a predetermined time has passed from the spraying operation start time t ₀ . These functions are for ensuring safety to humans and for preventing cockroaches from becoming ineffective as they become accustomed to insecticides.

However, this timer operation is valid within the set time of the main timer 9 when the other individual timers are OFF. In addition, this timer 25 for cockroaches
In, the temporal description of "every other day" or "10 hours" is
It is merely an example for implementation, and is not limited to this because it changes in consideration of habits of pests and safety for humans.

The fly / mosquito timer 26 is an individual timer for exterminating flies and mosquitoes. When it is turned on, a built-in lamp (not shown) lights up, and from the spraying operation start time t ₀ set by the main timer 9. The intermittent operation is performed every day for a predetermined time, for example, every hour during the time period until the spraying operation end time t ₁ .

[0038] This is based on the fact that flies and mosquitoes overlap with the activity hours of humans, and that the insecticide used is a respiratory poison, so it is not effective unless it is actively moving around. is there. That is, most of the flies and mosquitoes are exterminated by the short-term spraying of the insecticide, and during the next spraying stop time, the insecticide sprayed up to that point is removed by ventilation fans, people, and air. This is in consideration of the fact that the concentration to the human body can be dramatically improved because the concentration is diminished by decomposition due to moisture in the inside.

However, this timer operation is valid within the set time of the main timer 9 when the other individual timers are OFF. In the fly / mosquito timer 26, the temporal description of "every hour" is not limited to this from the same meaning as the cockroach timer 25.

The one-rotation action timer 27 operates from the spraying operation start time t ₀ set by the main timer 9 to the spraying operation end time t.
Do only once a spraying operation up to _1. This does not require continuous use every day or every other day, and allows the insecticide to be applied only once when necessary.

When the time from t ₀ to t ₁ set by the main timer 9 exceeds the standard operating time determined in consideration of the influence of insecticide on humans, for example, 6 hours. Alternatively, the spraying operation may be forcibly stopped when the standard operation time elapses.

The heater lamp 28 lights up when a heater 30 described later is operating, and the alarm lamp 29 blinks yellow when an abnormality occurs in the operation of the fan 5 or the opening / closing operation of the shutters 11 and 12. That is, except when the power is turned off (for example, when the power is cut off or the power cord is suddenly pulled out), when the fan 5 stops, the shutters 11 and 12 are designed to close in conjunction with it. Even if the fan 5 is stopped even if it is not cut, the shutter is released.
This is to warn the user when the 11 and 12 do not close.

Next, FIG. 6 (a) shows an indoor pesticide sprayer 1
1 shows a state in which the lid 16 is removed, an internal space portion 4 communicating with the intake port 2 and the outlet port 3 is provided, and a fan 5 is provided between the internal space portion 4 and the intake port 2. A heater 29 is provided on the back side of the space 4.

Further, as shown in FIG. 6 (b), the lid 16 has
A cassette container 31 is detachably attached to the back surface of the lid 16, and a plurality of holding protrusions 32 are formed on the cassette container 31 so that a plurality of insecticides 15 can be installed between the holding protrusions 32. I have to.

Therefore, conventionally, the pesticide 15 was exchanged at the site where the indoor pesticide sprayer 1 is installed (a narrow place such as a kitchen). However, in the present invention, the pesticide 15 is replaced at another wide place. It can be easily replaced by the unit of cassette container 31 in which 15 is set.

The chemical used for the insecticide 15 is a product name DD which has a high vapor pressure and has a property of continuing to emit at room temperature.
VP (generic name dichlorvos) is used, which is a respiratory poison for pests, and the amount to be applied indoors is an insecticide 15
Adjust according to the number of. For example, the size of the insecticide 15 is long
In the case of a plate with a width of 250 mm, a width of 65 mm, and a thickness of 6 mm, one insecticide is used per 2 tsubo when used for controlling flies and mosquitoes, and 2 insecticides per 1 tsubo when used for controlling cockroaches.
Use 15.

Further, the insecticide 15 is a plate-like plastic containing DDVP, and its insecticidal effect is about 3 months in the case of the above-mentioned size, and its transpiration occurs when the temperature is 22 to 23 degrees. The amount increases. The insecticide is not limited to DDVP.

FIG. 7 is a sectional view of the indoor pesticide sprayer 1 as seen from the side. The suction port 2 can be rotated around a shaft 11a to be moved to an open state and a closed state. Shutter
Equipped with 11. The shutter 11 is connected to one end of a rotating member 33a via a connecting member 33.
33a is a motor having the other end inside the indoor insecticide sprayer 1
It is fixed to the shaft of 13.

Accordingly, when the motor 13 is driven, one end of the connecting member 33 pulls the connecting member 33 rearward as the rotating member 33a rotates, and accordingly, the shutter 11 rotates about the shaft 11a as shown by the dotted line. While moving backward, the suction port 2 is opened. Then, by driving the motor 13 in the reverse direction, the shutter 11 is pushed out forward, and is rotated around the shaft 11a to close the suction port 2.

Similarly, the outlet 3 is provided with a shutter 12 which is rotatable about a shaft 12a and is movable between an open state and a closed state. The shutter 12 is connected to one end of a rotating member 34a via a connecting member 34.
The other end is fixed to a shaft of a motor 14 provided inside the indoor insecticide sprayer 1.

Therefore, when the motor 14 is driven, the rotating member 34a is rotated to pull the connecting member 34 rearward at one end thereof, and the shutter 12 is accompanied by the shaft 12a as shown by the dotted line.
While rotating around the center, it moves backward to open the outlet 3. Then, by driving the motor 14 in the reverse direction, the shutter 12 is pushed forward and rotated about the shaft 12a to close the air outlet 3.

The operation of the motors 13 and 14 and that of the fan 5 are interlocked. That is, when the spraying operation control unit 7 issues the shutter driving signals for the shutters 11 and 12 together with the driving signal for the fans 5, the fan 5 rotates (enters the use mode) and the motors 13 and 14 cause the shutters 11 and 12 to operate. Is driven rearward to open the inlet 2 and the outlet 3.
In order to reduce the cost exclusively, the opening and closing of the shutter may be performed manually without using the motor.

Then, the air taken in from the suction port 2 by the rotation of the fan 5 enters the internal space portion 4, and when passing through the plurality of insecticides 15 there, it is mixed with the vaporized insecticide and then mixed. It will be discharged from the air outlet 3.

When the spraying operation control section 7 issues the shutter closing signals for the shutters 11 and 12 together with the fan 5 stopping signal, the fan 5 is stopped (in the non-use mode) and the motors 13 and 14 are The shutters 11 and 12 are driven in a direction to push them forward to close the suction port 2 and the blowout port 3. Therefore, the internal space 4 is shielded from the outside, and the vaporized insecticide does not inadvertently flow out.

By the way, when the temperature of the air taken in from the suction port 2 is low, the divergence of the insecticide may be hindered, and the insecticide may not be effectively sprayed, so that the desired effect may not be obtained. First, the heater 30 provided on the back side of the space 4 is operated to raise the temperature in the space 4 so that the insecticide is effectively released. The heater 30 is mainly a surface heater of 100V and 100W, but the heater is not limited to this.

As a method of operating the heater 30, when the power switch 8 is turned on, a manual switch is used to forcibly operate the heater 30 at an arbitrary time, or a thermostat is used to set the inside of the space portion 4 to a predetermined value. There are a method of operating when the temperature is reached, a method of operating using a thermostat connected in series with the manual switch, and the like.

Further, the heater 30 is operated only during the operation of the fan 5, so that the interior of the space 4 is unnecessary when the spraying operation is not performed, that is, when the fan 5 is stopped. It is also possible not to heat. In addition, the above-mentioned thermostat is O when the intake air is at a predetermined temperature, for example, between 25 degrees and 12 degrees.
N is used.

In addition, the indoor insecticide sprayer 1
When used for mosquito control, it is desirable to position the air outlet 3 at a position slightly higher than the head of a person, and when used for cockroach control, a setting time of about 8 hours is used as a guide,
In addition, it is desirable that the outlet 3 is located at the feet.

[0059]

INDUSTRIAL APPLICABILITY The indoor insecticide sprayer of the present invention is provided with shutters at the inlet and the outlet, and the movement of the shutter opens and closes the inlet and the outlet. Accordingly, the communication between the space and the outside can be blocked, preventing the insecticide installed in the space from being released to the outside unnecessarily, ensuring safety for the human body and at the same time It is possible to prevent wasteful emission.

Further, by interlocking the driving / stopping of the fan with the opening / closing of the shutter, it is possible to surely close the inlet and the outlet by the shutter in the non-use mode in which the fan is stopped. .
