[0002]

2. Description of the Related Art Conventionally, as an electronic mosquito trap, an electric fragrancer, etc., a transpiration liquid holder for impregnating a predetermined transpiration liquid (insecticide, fragrance liquid, etc.) and for heating and evaporating this transpiration liquid And a vaporizer provided with the vaporization means are widely used.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In this type of evaporator,
Once the power switch is operated to bring it into a used state, it is general to continue heating and evaporating a certain amount of the evaporated liquid into the used space. Therefore, use of this type of vaporizer often consumes unnecessary vaporizing liquid and incurs unnecessary running costs. On the other hand, even for a person who lives in the use space, it is sufficient that the amount of the transpiration liquid drifting in the space is such that the effects of insecticide, aroma and the like are exhibited. In particular, when the user is a child, an elderly person, a sick person, etc., it is desirable that the concentration of the evaporated liquid in the use space is set to the minimum necessary.

The present invention has been made in view of the above point of view, and an object thereof is to provide a vaporizer capable of appropriately adjusting the concentration of the vaporized liquid in the use space.

[0005]

The vaporizer of the first aspect of the present invention comprises:
A vaporization liquid holder for impregnating a predetermined vaporization liquid, a vaporization means for appropriately vaporizing the vaporization liquid by heating, a state changeover switch for selecting a used state and an unused state, and the vaporization means And a vaporization operation for operating the vaporization means for a first predetermined time when the use state is selected by the state changeover switch. The standby operation of stopping the operation of the evaporation means for a second predetermined time is alternately performed. The above-mentioned "transpiration" means releasing or evaporating a vaporized liquid or the like into the use space.

The "state changeover switch" is used to switch between a used state and a non-used state. Also,
The operation control means repeatedly performs the evaporation operation and the standby operation when the evaporator of the present invention is in use. In the present invention, the operation control means is mainly used to adjust the amount of heat vaporization of the vaporized liquid into the use space. Further, the "used state" is a state in which the evaporation operation of the evaporation liquid and the stopping of the evaporation operation for adjusting the concentration are repeated. Furthermore, the "non-use state" is a state in which the evaporation liquid is not evaporated at all. Then, when it is desired to heat and evaporate the evaporated liquid of a desired concentration into the use space, the state changeover switch is operated to bring the vaporizer into the use state, and otherwise, the vaporizer is not used.

Here, the "transpiration operation" is to heat and evaporate the evaporation liquid by the evaporation means, and the "standby operation" is to adjust the amount of the evaporation liquid to be heated and evaporated into the use space. It means waiting without evaporating the evaporated liquid. The “first predetermined time” is the time during which one evaporation operation is performed among the evaporation operations that are alternately repeated in one usage state. And "second predetermined time"
Is the time during which one standby operation is performed among the standby operations that are alternately repeated in one usage state.

According to the second aspect of the present invention, there is provided operation input means for inputting the first predetermined time and the second predetermined time,
The operation control means includes an operation storage means for storing the first predetermined time and the second predetermined time. Therefore, in this electronic mosquito trap, the first predetermined time and the second predetermined time selected by the user are input, and based on this, the concentration of the evaporated liquid in the use space can be appropriately adjusted. .

Further, as shown in the third aspect of the present invention, in the second aspect of the present invention, the selection switch section is provided, and the operation storage means has a plurality of combinations of the first predetermined time and the second predetermined time in advance. It is stored, by the selection switch unit,
It is also possible to select a predetermined combination from the plurality of combinations. By adopting such an input method, the concentration of the evaporated liquid in the use space can be made close to the desired concentration without complicated setting. Further, the selection switch section may be the same as the operation input means.

The first predetermined time and the second predetermined time may be constant or variable throughout one use state. For example, as shown in the fourth aspect of the present invention, the operation control means may cause the first evaporation operation in one usage state to be performed for a longer period of time than the subsequent evaporation operation in the one usage state. That is, according to the fourth aspect of the present invention, in the initially unused state, there is no evaporated liquid in the used space,
When the vaporizer of the present invention is put into use, the vaporization liquid concentration in the use space can be quickly increased to a desired vaporization liquid concentration by first performing the vaporization operation for a long time. In addition, increase the concentration of transpiration liquid to the desired transpiration liquid concentration, maintain the concentration for a certain period of time to exert the effect of transpiration liquid sufficiently, then gradually shorten the first predetermined time The concentration of the evaporated liquid may be lowered.

Further, according to the fifth aspect of the invention, the state switching control unit having the time storage means for storing the scheduled time, the time input means for inputting the scheduled time, and the passage of time are measured. And time measuring means. The state switching control unit detects that the scheduled time stored in the time storage unit has elapsed by the time measurement unit,
The vaporizer is shifted from a use state to a non-use state or from a non-use state to a use state.

The "state switching control section" of the vaporizer of the fifth aspect of the present invention automatically switches between the use state and the non-use state after a predetermined time has elapsed from the present time.
However, this state switching control unit can switch not only from the used state to the unused state but also from the unused state to the used state. The function of the state switching control unit, including the function of the operation control unit,
The same IC can be used, or multiple ICs can be used.
It can also be achieved. Further, the time input means may be the same as the operation input means and the selection switch section, or may be realized by two or more input means.

In the vaporizer of the fifth aspect of the invention, when the time measuring means is set to return the elapsed time to 0 when 24 hours have passed from the reference time, the scheduled time for shifting from the used state to the unused state By simply storing the scheduled time for shifting from the non-use state to the use state once, the present evaporator can be put into the use state from the same time to the same time every day. Since the vaporizer of the fifth aspect of the invention does not need to recognize the current time in order to exert its function, it does not need to be equipped with a standby power source for the case where the power supply is cut off. Further, a device such as an IC for realizing the control function can be simplified.

Further, as shown in the sixth aspect of the present invention, a state switching control section having a time storage means for storing the operation start time and the operation end time, and the operation start time and the operation end time are input. And a clock unit for recognizing the current time, and the state switching control unit confirms that the operation start time stored in the time storage unit by the clock unit has come. Recognizing that the vaporizer is changed from the non-use state to the use state, or the clock section recognizes that the operation end time stored in the time storage means has been reached, and the use state is not used. The state may be changed. This "state switching control unit"
Is to automatically switch between a used state and a non-used state at a predetermined time. It should be noted that the function of the state switching control unit is the same, including the function of the operation control means.
It can be performed by C or can be performed by a plurality of ICs. Further, the time input means may be the same as the operation input means, the selection switch section and the time input means, or may be realized by two or more input means.

The fifth and sixth inventions have been made from the following viewpoints. That is, conventionally, an electronic mosquito trap having a timer function of automatically turning on / off the switch has been proposed (JP-A-3-1801).
34). However, even when this electronic mosquito trap is in use, it constantly heats and evaporates a certain amount of transpiration liquid into the use space, and adjusts the concentration of the transpiration liquid in the use space. It was difficult to do so. On the other hand, the vaporizers of the fifth and sixth inventions can adjust the concentration of the vaporized liquid in the use space. Furthermore, it is a vaporizer having a timer function.

The vaporizer according to the seventh aspect of the present invention comprises a light emitting portion which is mounted so as to be visible from the outside, and a light emission control means which raises or lowers the luminance of light emitted from the light emitting portion. The change pattern of the luminance is such that it gradually increases from a constant luminance state (including the extinguished state) to a predetermined luminance, then gradually decreases, returns to the original luminance, and gradually increases again, and this is repeated. Is. According to the present invention, since the light emitting unit blinks while the brightness increases and decreases, it is possible to emit a firefly-like light. The function of the light emission control means, including the functions of the state switching control section and the operation control means, can be fulfilled by the same IC, or can be fulfilled by a plurality of ICs. .

The vaporizer according to the eighth aspect of the invention is the vaporizer according to the seventh aspect of the invention, only when the light emission control means is in use.
The light emitting unit is turned on. Therefore, according to the present invention, it is possible to know whether it is in use or not, even in the dark. In the vaporizer of the ninth aspect of the present invention, in the seventh aspect of the invention, the light emission control means lights the light emitting portion only when the vaporization means is performing the vaporization operation. Therefore, according to the present invention, it is possible to know whether the evaporation means is in the evaporation operation or in the standby operation even in the dark. The functions of the eighth and ninth inventions, including the functions of the state switching control section and the operation control means, can be fulfilled by the same IC, or by a plurality of ICs.

Further, the electronic mosquito repellent of the present embodiment has options for those numerical values in advance, and each setting value is determined by allowing the user to select the option, so the operation at the time of use is simple. . In addition, since the functions of ICs are limited, they are inexpensive.

Embodiment 2 In this embodiment, the vaporizer of the present invention is applied to an electronic mosquito trap. The electronic mosquito repellent of the present embodiment allows a user to input a scheduled time, an operation start time, etc. by numerical input, and adjusts the concentration of the evaporated liquid in the use space according to these instructions. The difference between the operations will be mainly described below.

(1) Configuration of Electronic Mosquito Repellent The configuration of the electronic mosquito repellent of this example is almost the same as that of the first embodiment. However, an input panel 7 (not shown) is provided for the user to input the scheduled time, the operation start time, and the like.

Since the operation of the electronic mosquito trap of this embodiment is different from that of the electronic mosquito trap of the first embodiment, the IC 6 will be described in detail below. The IC 6 performs the function of the state switching control unit, the function of the operation control unit, and the function of the light emission control unit. In the following, the portion that performs the function of the state switching control unit will be referred to as the state switching control unit 61, the portion that performs the function of the operation control unit will be referred to as the operation control unit 62, and the portion that performs the function of the light emission control unit will be referred to as the light emission control unit 63. To do. Also, I
C6 is a clock unit 64 capable of recognizing the current time,
A triac control unit 65 that performs AC voltage control, a state switching control unit 61, an operation control unit 62 when the power is turned on,
A reset unit 66 for initializing the issue control unit 63 and the like is provided.

As shown in FIG. 6, the state switching control section 61 includes a clock section 64 for recognizing the current time, and an input panel 7 for inputting an operation start time and an operation end time.
Is connected to The state switching control unit 61 also includes a time storage unit 6 that stores the operation start time and the operation end time.
11 is provided. And the information from the clock unit 64,
When the operation start time is recognized from the information from the time storage unit 611, the electronic mosquito trap is changed from the non-use state to the use state, and when the operation end time is recognized, the electronic Change the mosquito trap from the used state to the unused state. By using the clock unit 64 as a 24-hour counter,
The electronic mosquito repellent device can be put into use at a predetermined operation start time every day and not in use at a predetermined operation end time even if the user does not perform any operation. However, when the user directly operates the state changeover switch 5, the selection of the use state or the non-use state of this electronic mosquito trap has priority over the instruction of the state change control unit 61.

The operation control section 62 is connected to the heating section 4, and in the use state, the heating section 4 changes with time.
Is energized to cause the evaporated liquid to evaporate, and the energization is stopped to perform a standby operation, and these switchings are repeated. I
C6 is connected to the input panel 7. Also, IC6
The operation storage unit 621 included in the operation control unit 62 stores the combination of the first predetermined time / the second predetermined time in advance. For example, the first predetermined time 3.5 minutes / the second predetermined time 1.
Combination of 5 minutes (combination "1"), first predetermined time 3.5 minutes / second predetermined time 2.0 minutes combination (combination "2"), first predetermined time 3.5 minutes / second predetermined time A combination of 2.5 minutes (combination “3”) and the like are stored. The degree of heat evaporation of the evaporated liquid decreases in the order of the combination “1”, the combination “2”, and the combination “3”. Then, the user considers the size of the room, the degree of sealing, etc. through the input panel 7 from among them,
The most preferred combination can be selected.
It is also possible to make a selection in consideration of user groups (adults, children, etc.).

The input panel 7 displays the operation start time,
The end time of operation and the degree of heat evaporation of the evaporated liquid "1",
It is for inputting "2" or "3", and is provided with a liquid crystal window for displaying 4-digit alphanumeric characters and an input mode, a mode changeover switch, and an increase / decrease switch. Then, the user switches between the "operation start time input mode", the "operation end time input mode" and the "heated evaporation degree input mode of evaporating liquid" by means of the mode changeover switch, and the increase / decrease switch in each mode The number displayed on the liquid crystal window is increased or decreased to set the value to your liking.

In addition, the first first predetermined time period after entering the use state is a combination of the first predetermined time period / second predetermined time period determined according to the degree of the heat transpiration amount (for example, the above combination "1", " 2 "and" 3 ") are longer than the first predetermined time after the second time. By doing so,
As shown in FIG. 3, it is possible to quickly raise the concentration of the evaporating liquid in the use space to a predetermined desired concentration from the state in which the evaporating liquid is not contained in the use space. Further, the first first predetermined time after entering the use state is a combination of the first predetermined time / second predetermined time determined according to the degree of the heat transpiration amount (for example, the above combination “1”, “2”, It is independently defined for each "3". The first predetermined time and the second predetermined time after the second use after entering the use state may be constant throughout one use state or may be changed.

In the electronic mosquito trap of this embodiment, the change pattern of the brightness of the LED of the light emitting section 8 is as shown in FIG. The change in the brightness of the light emitting unit 8, that is, the LED by the light emitting control unit 63 of the IC 6 is L by the PWM control.
This is realized by changing the voltage applied to the ED as shown in FIG. 8 according to time. That is, as shown in FIGS. 7 and 8, the duty ratio is 0, that is, 1573 mse from the OFF state.
c (T ₁ ), through 128 steps, the duty ratio is gradually increased to 100%, and then the duty ratio of 100% is changed to 396 msec (T ₂ ).
Maintained, then again the duty ratio is 1573m
It gradually decreases over sec (T ₃ ) and returns to the OFF state. And, during 140 msec (T ₄ ), OF
Maintain F state. The light emission control unit 63 repeats this for the voltage applied to the LED. In FIG. 8,
T ₀ is the period, T ₀₁ is the pulse width, and T ₀₂ is the period minus the pulse width.

With the PWM control as described above, by blinking the LED while slowly changing the brightness, it is possible to cause the LED, that is, the light emitting section 8 to emit light having a firefly-like image. As indicated by the broken line in FIG. 7, after the duty ratio is reduced to the OFF state, the brightness change pattern is such that the duty ratio is gradually increased without maintaining the OFF state for 140 msec (T ₄ ). May be Also, after the duty ratio is increased to 100%, the luminance change pattern may be such that the duty ratio is gradually decreased without maintaining the state of the duty ratio of 100% for 396 msec (T ₂ ).

The light emission control section 63 causes the light emitting section 8 to emit light only when the heating section 4 is in use. Therefore, the user can confirm whether or not the electronic mosquito trap is in use even in the dark, and can easily confirm the location of the electronic mosquito trap when in use. In this electronic mosquito trap, the user does not directly select the combination of the first predetermined time / the second predetermined time, but the user uses 4.5 tatami mats,
The size of the room, such as 6 tatami, 8 tatami, and 12 tatami, and the degree of heat evaporation of the evaporated liquid, high, medium, and low are independently selected, and the operation controller 62 sets the first predetermined time /
It is also possible to determine the combination of the second predetermined times.

In the present embodiment, when the user directly operates the state changeover switch 5, it is given priority over the instruction of the state changeover control section 61, but such a function is not provided. It can also be one. Conversely, IC
6, the state switching control unit 61 may not be provided, and the switching between the used state and the unused state may be performed only by the user directly operating the state switching switch 5. Further, the electronic mosquito repellent device may not include the light emitting unit 8, that is, the LED.
Further, the configuration of the IC 6 and the control content of the light emitting unit 8 shown in this embodiment are the same in the first embodiment.

(2) Effect of electronic mosquito trap As described above, since this electronic mosquito trap is equipped with the operation control means and the operation input means, the time for the evaporation liquid to be heated and vaporized in the use space depends on the user. It can be adjusted as desired.

The present invention is not limited to the specific examples described above, and various modifications may be made within the scope of the present invention depending on the purpose and application. That is, although the electronic mosquito trap is used in this embodiment, the present invention can be applied to the aroma device by using the aroma liquid as the evaporation liquid. The case body 1 may be made of metal. Furthermore, if the above-mentioned evaporation liquid container 2 can store the evaporation liquid,
It may be glass or other material. The color of the LED may be yellowish green, green, yellow, orange, red or blue. The change pattern of the brightness of the LED is not limited to the numerical values and the change patterns shown in the above embodiment, but various patterns such as a sine wave pattern can be used.

By using a custom IC as the IC 6, the manufacturing cost can be reduced. If the IC is a custom IC, so-called minor changes and model changes must be redesigned, but by designing in advance the functions after minor changes and after model changes from the beginning in anticipation of minor changes and model changes. , The above problem can be solved. In addition, this electronic mosquito trap has multiple LEDs arranged at appropriate positions,
You can also give the appearance that multiple fireflies are flying.

In addition, the operation control unit applies PWM to the heating unit.
By performing control, the amount of the evaporated liquid heated and evaporated by the electronic mosquito trap in the use space can be changed according to time. As a result, at the beginning of the state of use, a large amount of the heat-transpiration of the transpiration liquid was set in the use space to exert an insecticidal action or an aroma action, and the mosquito-free stage or sufficient aroma spread throughout the room. In the stage, the amount of heat evaporation of the evaporated liquid into the use space may be set to a low level so that the insect repellent effect or the aroma effect can be maintained and exerted. This makes it suitable for use in a completely closed room (for example, a room in which the air conditioner is in an operating state). Further, the present electronic mosquito repellent device may be provided with a detection means such as an infrared ray detection sensor so that it can be sensed when a person approaches and put into a use state. However, since the sensor is usually expensive, by not using the sensor,
The electronic mosquito trap and the like can be made inexpensive.
