Description

TECHNICAL FIELD The present invention relates to space purification technology, and more particularly to a space purification device that sprays water containing hypochlorous acid water.

A space purifier sprays fine water particles such as chemicals, such as hypochlorous acid water, in order to sterilize or deodorize a target area. For example, the liquid atomization chamber of the space purification device releases water droplets from the hypochlorous acid aqueous solution stored in the water reservoir. Water droplets are ventilated by an air blower and are discharged to a target area from an air outlet through an air passage (see, for example, Patent Document 1).

However, in the conventional space purifying device, when the amount of humidification required for the living space (humidification demand) is small (for example, the mid-season and summer in Japan), the purification component (hypochlorous acid) released into the living space Since the amount is reduced, it becomes difficult for the purification component to be released into the indoor space. In other words, with conventional space purifiers, if hypochlorous acid is supplied to the space based only on the amount of humidification, the amount of purifying components released into the indoor space (into the air) increases when the demand for humidification is low. There was a problem that it was not easy to make

By doing so, under the condition that the heating operation of the air conditioner is substantially stopped, the finer part is caused to perform the rotation operation based on the required amount of hypochlorous acid, so that the living space is filled with a predetermined amount of water. The amount of hypochlorous acid released into the living space can be adjusted without creating a situation in which the release of hypochlorous acid is difficult.

Moreover, in the space purification device according to the present invention, the control unit may execute the second control mode when the operation mode information indicates that the operation of the air conditioner is to be stopped.

<Operation related to electrolysis treatment in the hypochlorous acid water generating unit>
The control unit 60 causes the following processes to be executed as operations related to electrolysis processing in the hypochlorous acid water generating unit 30 (electrolysis tank 33).

The control unit 60 receives information (operation stop information) on stopping the operation of the hypochlorous acid water supply unit 38 (hypochlorous acid water conveying pump 36) and the It receives information about time (time information) and outputs it to the processing unit 64 .

The processing unit 64 identifies the control information based on the operation stop information from the hypochlorous acid water supply unit 38, the time information from the clock unit 61, and the setting information from the storage unit 62, and outputs to the output unit 65 Output.

More specifically, first, the salt water conveying pump 32 is kept stopped based on the signal from the output section 65, and the hypochlorous acid water conveying pump 36 is stopped based on the signal from the output section 65. maintain state.

Then, the electrolytic cell supply valve 35 is opened based on the signal from the output section 65 . As a result, supply of tap water from the water supply pipe 47 is started to the electrolytic cell 33 . After that, the electrolytic cell supply valve 35 is closed based on the signal from the output section 65 that receives the water level information (full water) from the water level sensor 44a. As a result, the electrolytic bath 33 is supplied with tap water at the set supply rate.

Next, the salt water conveying pump 32 starts operating based on a signal from the output section 65, conveys a predetermined amount of salt water to the electrolytic cell 33, and then stops. As a result, the chloride ions of the salt water are dissolved in the tap water, and the electrolytic cell 33 is brought into a state where an aqueous solution (chloride aqueous solution) containing a predetermined amount of chloride ions is generated.

Based on the signal from the output unit 65, the electrode 34 starts electrolyzing the chloride aqueous solution, generates hypochlorous acid water under the set conditions, and stops the electrolysis. The hypochlorous acid water generated by the electrode 34 has, for example, a hypochlorous acid concentration of 100 ppm to 150 ppm (eg, 120 ppm) and a pH of 7.0 to 8.5 (eg, 8.0). becomes.

As described above, the control unit 60 performs the electrolysis process in the electrolytic cell 33 of the hypochlorous acid water generating unit 30 to generate hypochlorous acid water having a predetermined concentration and amount.

<Operation related to supply processing of hypochlorous acid water to the miniaturization unit>
The control unit 60 causes the following processing to be executed as an operation (first supply operation) related to the hypochlorous acid water supply processing to the atomization unit 41 . In addition, below, the hypochlorous acid water supplied to the micronization part 41 by the first supply operation is also referred to as “hypochlorous acid water undiluted solution”.

The control unit 60 generates hypochlorous acid water based on the information on the reduction time required for the mixed water to decrease by a specified amount as a trigger for the hypochlorous acid water supply process to the atomization unit 41. A hypochlorous acid water supply request is output to the unit 30 (hypochlorous acid water supply unit 36).

Specifically, the processing unit 64 identifies the control information based on the information about the decrease time and the setting information from the storage unit 62 and outputs the control information to the output unit 65 . Here, the setting information includes information about the hypochlorous acid water supply timing and information about the ON/OFF operation of the hypochlorous acid water transfer pump 36 .

Then, the output unit 65 outputs a signal (control signal) to the hypochlorous acid water transfer pump 36 of the hypochlorous acid water supply unit 38 based on the received control information.

The hypochlorous acid water transfer pump 36 operates based on a signal from the output section 65 . As a result, in the hypochlorous acid water generating unit 30, supply of the hypochlorous acid water undiluted solution from the electrolytic bath 33 to the atomization unit 41 (mixing bath 42) is started. In addition, in order to ensure the concentration of the hypochlorous acid water stored in the electrolytic cell 33, when the hypochlorous acid water undiluted solution is supplied from the hypochlorous acid water generating unit 30 to the mixing tank 42, the electrolytic cell 33 The entire hypochlorous acid water undiluted solution thus produced is supplied.

After that, the hypochlorous acid water conveying pump 36 stops based on the signal from the output section 65 that receives the time information (required time for supplying the entire amount) from the clock section 61 . As a result, the hypochlorous acid water supply unit 38 supplies the hypochlorous acid water undiluted solution from the electrolytic bath 33 to the atomization unit 41 (mixing bath 42) at the set supply amount.

As described above, the control unit 60 causes the hypochlorous acid water supply unit 38 to supply hypochlorous acid from the hypochlorous acid water generation unit 30 (the electrolytic cell 33) to the micronization unit 41 as the first supply operation.

<Operation related to water supply processing to the miniaturization unit>
The control unit 60 causes the following process to be executed as an operation (second supply operation) related to the process of supplying water to the miniaturization unit 41 .

The control unit 60 outputs a water supply request to the water supply unit 48 as a trigger for the water supply process to the atomization unit 41, based on the information on the reduction time required for the mixed water to decrease by a specified amount. do.

Specifically, the processing unit 64 identifies the control information based on the information about the decrease time and the setting information from the storage unit 62 and outputs the control information to the output unit 65 . Here, the setting information includes information on water supply timing and information on on/off operation of the mixing tank supply valve 45 .

Then, the output unit 65 outputs a signal (control signal) to the mixing tank supply valve 45 based on the received control information.

The mixing tank supply valve 45 operates based on the signal from the output section 65 . As a result, the water supply unit 48 starts supplying water from the external water supply pipe to the micronization unit 41 (mixing tank 42 ) via the water supply pipe 47 .

After that, the mixing tank supply valve 45 is stopped based on the signal from the output section 65 that receives the water level information (full water signal) from the water level sensor 44 a of the miniaturization section 41 . Thereby, the water supply unit 48 supplies water from the water supply pipe 47 to the atomization unit 41 (mixing tank 42) until the set amount of water is reached.

As described above, the control unit 60 causes the water supply unit 48 to supply water from the water supply pipe 47 to the miniaturization unit 41 as the second supply operation.

<Operations related to humidification and purification processing in the miniaturization unit>
Next, the operation related to the humidifying and purifying process in the miniaturization unit 41 performed by the control unit 60 will be described.

The input unit 63 receives user input information from the operation panel 50, temperature and humidity information (information on temperature and humidity) of the air in the living room 2 from the indoor temperature and humidity sensor 12, and information on the air conditioning room 18a from the intake temperature and humidity sensor 14. Air temperature and humidity information (information on temperature and relative humidity), outdoor air temperature information (information on temperature) from the outdoor temperature sensor 16, hypochlorous acid water (mixed water ) and receive the water level information. The input unit 63 outputs each received information to the processing unit 64 .

The clock unit 61 outputs time information regarding the current time to the processing unit 64 .

The storage unit 62 stores the user input information received by the input unit 63 and information on the number of revolutions in the centrifugal crushing unit with respect to the temperature and relative humidity of the air flowing into the atomization unit 41 (rotation based on the required humidification amount in the first control mode). and information on the number of rotations based on the hypochlorous acid demand in the second control mode, etc.). The storage unit 62 outputs various stored information to the processing unit 64 in response to a request from the processing unit 64 .

The processing unit 64 receives various types of information from the input unit 63 (user input information, temperature/humidity information, outside air temperature information, information on the required amount of additional air purification components), time information from the clock unit 61, and information from the storage unit 62. Various information (rotational speed information) is received. The processing unit 64 uses the received various information to identify control information related to the humidifying and purifying operation in the first control mode or the second control mode.

The first control mode is a mode for controlling the number of rotations of the miniaturization unit 41 specified based on the required amount of humidification to the living room 2 . The first control mode is mainly executed during a period when the relative humidity in the living room 2 is low and the amount of humidification can be increased (for example, winter in Japan). More specifically, in the first control mode, the air conditioner 13 is in the heating operation, and the set temperature of the living room 2 (room set temperature) and the outside air temperature acquired from the outdoor temperature sensor 16 Executed if the temperature difference is greater than the reference temperature. Here, the reference temperature is set to 6° C., for example. The first control mode is, for example, 600 rpm to 4000 rpm based on the humidity difference between the target humidity stored in the storage unit 62 and the humidity (for example, absolute humidity) of the air in the living room 2 from the indoor temperature and humidity sensor 12. is set to the number of revolutions in the range of

In the present embodiment, the finer part 41 controls the stop state and the drain state of the hypochlorous acid water stored in the mixing tank 42 by rotating the pumping pipe 43a. More specifically, in the atomization unit 41 , the pumping pipe 43 a is arranged at a predetermined position directly above the drain port (not shown) of the mixing tank 42 . The miniaturization unit 41 starts the humidifying and purifying operation, and when the pumping pipe 43a rotates, the centrifugal force of the rotation causes a vortex (not shown) in the hypochlorous acid water in the mixing tank 42 inside the pumping pipe 43a. Occur. The pumping pipe 43a forms a gap (not shown) that communicates between the tip opening of the pumping pipe 43a and the drain port at the center of the vortex generated by its rotation. As a result, the void blocks the drain port, and the hypochlorous acid water in the mixing tank 42 is prevented from flowing into the drain port. That is, in the miniaturization unit 41, during the humidifying and purifying operation (during the rotating operation of the pumping pipe 43a), the water is stopped, and the hypochlorous acid water in the mixing tank 42 can be suppressed from being drained from the drain port. can. On the other hand, when the rotation of the pumping pipe 43a is stopped, the gap disappears along with the swirl, and the hypochlorous acid water in the mixing tank 42 flows into the drain port. That is, in the miniaturization unit 41, by stopping the humidifying and purifying operation (rotating operation of the pumping pipe 43a), the water is discharged, and the hypochlorous acid water in the mixing tank 42 can be discharged from the drain port. For this reason, in the miniaturization unit 41, even when it is determined that humidification and purification are not required, the number of rotations of the pumping pipe 43a is set to the minimum rotation speed (water stop rotation speed ), and the lower limit rotation speed in the first control mode is set to 600 rpm.

The second control mode is a mode for controlling the number of revolutions of the miniaturization unit 41 specified based on the amount of hypochlorous acid required for the living room 2 . The second control mode is mainly executed during periods when the required amount of humidification to the living room 2 is low (for example, mid-season and summer in Japan). More specifically, the second control mode is executed when any one of the following three conditions (Conditions 1 to 3) is satisfied. Here, the required amount of hypochlorous acid is the amount of hypochlorous acid to be supplied to the living room 2. For example, the user inputs the target supply amount level of hypochlorous acid to the operation panel 50 as "high", "standard ”, and “small”. In the second control mode, based on the target hypochlorous acid supply amount level stored in the storage unit 62, the rotational speed is set to a range of, for example, 600 rpm to 4000 rpm.

Condition 1: The air conditioner 13 is in a stopped state.

Condition 2: The air conditioner 13 is in cooling operation.

Condition 3: The air conditioner 13 is in heating operation, and the temperature difference between the set temperature of the living room 2 (room set temperature) and the outside air temperature obtained from the outdoor temperature sensor 16 is equal to or lower than the reference temperature. .

In addition, in the second control mode, in a situation where the required amount of humidification to the living room 2 is small, priority is given to the rotation speed of the miniaturization unit 41 specified based on the required amount of humidification, and the required amount of hypochlorous acid is prioritized. This can also be said to be a mode in which the humidification/purification operation is executed at the rotation speed of the miniaturization unit 41 specified based on the above.

The processing unit 64 will be specifically described.

The processing unit 64 detects the humidity difference between the target humidity stored in the storage unit 62 and the temperature/humidity information of the air in the living room 2 from the indoor temperature/humidity sensor 12 at regular time intervals based on the time information from the clock unit 61. , the required humidification amount required for the living room 2 is specified. In addition, the processing unit 64 identifies the required amount of hypochlorous acid required for the living room 2 based on the target supply amount level of hypochlorous acid stored in the storage unit 62 . Then, the processing unit 64 specifies control information (humidification control information) relating to the humidifying and purifying operation operation based on the specified humidification required amount and hypochlorous acid required amount, and the rotational speed information stored in the storage unit 62. . The processing unit 64 then outputs a signal related to the identified control information to the output unit 65 . In addition, the processing unit 64 specifies an operation for supplying hypochlorous acid water (first supply operation) and an operation for supplying water (second supply operation). The processing unit 64 then outputs a signal related to the identified control information to the output unit 65 . The supply control information includes a hypochlorous acid water supply request signal and a water supply request signal.

Then, the output unit 65 outputs the received signals to the miniaturization unit 41, the hypochlorous acid water supply unit 38, and the water supply unit 48, respectively.

The hypochlorous acid water supply unit 38 receives a signal from the output unit 65 (hypochlorous acid water supply request signal included in the supply control information), and based on the received signal, the above-described micronization unit 41 An operation (first supply operation) related to supply processing of hypochlorous acid water to the mixing tank 42 is performed at a predetermined supply timing. Further, the water supply unit 48 receives a signal (a water supply request signal included in the supply control information) from the output unit 65, and supplies water to the mixing tank 42 of the miniaturization unit 41 described above based on the received signal. (second supply operation) is executed at a predetermined supply timing.

Then, the miniaturization section 41 receives a signal from the output section 65 and controls the rotation operation of the centrifugal crushing unit 43 based on the received signal. More specifically, the miniaturization unit 41 performs a rotation operation set based on the required amount of humidification in the first control mode or a rotation operation set based on the required amount of hypochlorous acid set in the second control mode. , the humidifying and purifying process is performed on the air flowing inside (the purified air path 49). After that, the miniaturization unit 41 replenishes the decreased specified amount when the humidification purification process progresses and the mixed water decreases by a specified amount from the full water amount (when the water level information is obtained from the water level sensor 44b). Execute the first supply operation or the second supply operation.

Next, referring to FIG. 4, the rotation speed control operation of the miniaturization unit 41 in the control unit 60 of the space purification device 40 will be described. FIG. 4 is a flow chart showing the processing operation in the control unit 60 of the space cleaning device 40. As shown in FIG. In the following description, the description of the water or hypochlorous acid water supply processing operation and the waste water processing operation, which are executed during the humidification and purification processing operation, is omitted.

First, when the humidification/purification process is started, the control unit 60 acquires information on the operation mode (operation mode information) from the air conditioner 13 (step S01). The control unit 60 determines whether or not the operation of the air conditioner 13 is stopped based on the acquired operation mode information (step S02). Then, if the result of determination is that the air conditioner 13 has stopped operating (Yes in step S02), the control unit 60 determines that the condition 1 described above is satisfied, and instructs the miniaturization unit 41 to The humidification/purification operation in the second control mode is started (step S09). In addition, in the humidifying and purifying operation in the second control mode, the miniaturization unit 41 is set to a rotational speed (range of 600 rpm to 4000 rpm) specified based on the required amount of hypochlorous acid.

On the other hand, if the result of determination in step S02 is that the air conditioner 13 has not stopped operating, that is, is in operation (No in step S02), the control unit 60 performs , determines whether or not the air conditioner 13 is in heating operation (step S03). As a result of the determination, if the air conditioner 13 is not in the heating operation (No in step S03), the control unit 60 satisfies the condition 2 described above, that is, the air conditioner 13 is in the cooling operation. is specified (step S04), and the miniaturization unit 41 is caused to start the humidifying and purifying operation in the second control mode (step S09).

On the other hand, if the result of determination in step S03 is that the air conditioner 13 is in the heating operation (Yes in step S03), the control unit 60 specifies that the air conditioner 13 is in the heating operation ( step S05). Then, the control unit 60 calculates the temperature difference between the set temperature of the living room 2 (living room set temperature) input from the operation panel 50 and the outside air temperature detected by the outdoor temperature sensor 16 (step S06). Based on the obtained temperature difference information, the control unit 60 determines whether the temperature difference is greater than the reference temperature (step S07). As a result of the determination, if the temperature difference is not greater than the reference temperature, that is, if the temperature difference is equal to or less than the reference temperature (No in step S07), it is determined that the above-described condition 3 is satisfied, and the control unit 60 , causing the miniaturization unit 41 to start the humidifying and purifying operation in the second control mode (step S09).

On the other hand, if the result of determination in step S07 is that the temperature difference is greater than the reference temperature (Yes in step S07), the control unit 60 starts the humidifying and purifying operation for the miniaturization unit 41 in the first control mode. (step S08). In addition, in the humidifying and purifying operation in the first control mode, the miniaturization unit 41 is set to a rotation speed (in the range of 600 rpm to 4000 rpm) controlled based on the required humidification amount.

Specifically, in steps S03 to S09, if the air conditioner 13 is in cooling operation, the humidifying and purifying operation in the second control mode is performed. On the other hand, when the air conditioner 13 is in the heating operation and the set room temperature is 22° C. and the outside air temperature is 15° C., the temperature difference is 7° C., and the temperature difference 7° C. is larger than the reference temperature (6° C.). A humidifying and purifying operation is performed in one control mode. On the other hand, when the air conditioner 13 is in heating operation and the set room temperature is 22° C. and the outside air temperature is 20° C., the temperature difference is 2° C., and the temperature difference 2° C. is equal to or lower than the reference temperature (6° C.). Therefore, the humidifying and purifying operation is performed in the second control mode.

After that, the control unit 60 determines whether or not the time measured from the start time of the humidification/purification operation by the miniaturization unit 41 in step S08 or step S09 has passed a predetermined time (step S10). As a result of the determination, if the predetermined time has not elapsed (No in step S10), the control unit 60 continues the humidifying and purifying operation by the miniaturization unit 41 (returns to step S10). On the other hand, if the predetermined time has passed (Yes in step S10), the control unit 60 returns to step S01. Here, the predetermined time is an interval time for feedback control of humidification and purification, and is set to 5 minutes, for example.

As described above, in the space purification device 40, the miniaturization unit 41 performs the operation related to the humidification purification process.

Next, each control (first control mode, second control mode) in the humidifying and purifying operation of the miniaturization unit 41 will be described.

As described above, the first control mode is executed during the period when the relative humidity in the living room 2 is low and the amount of humidification can be increased (for example, winter in Japan). During such a period, the miniaturization unit 41 can release a predetermined amount of the space purification component (hypochlorous acid) into the living room 2 along with the humidification purification operation (humidification operation). That is, in such a period, when the release of hypochlorous acid to the living room 2 is requested, the miniaturization unit 41 performs a rotation operation (humidification purification operation in the first control mode) based on the required amount of humidification. , the amount of hypochlorous acid released to the living room 2 can be easily adjusted according to the required amount of humidification.

However, in the first control mode, the relative humidity of the air in the living room 2 is high during the mid-season in Japan (e.g., the transition period between summer and winter, which corresponds to spring or autumn in Japan) and summer.
It may be determined that the required amount of humidification to the living room 2 is small, or that humidification to the living room 2 is not necessary. In other words, it becomes difficult to release a predetermined amount of hypochlorous acid into the living room 2 .

Therefore, the second control mode is used when the required amount of humidification to the living room 2 is small (for example, mid-season and summer in Japan), that is, in a situation where it is difficult to release a predetermined amount of hypochlorous acid to the living room 2 in the first control mode. executed. In the second control mode, the rotation operation of the miniaturization unit 41 is executed at a rotation speed specified based on the hypochlorous acid demand amount, and hypochlorous acid is released into the living room 2 regardless of the humidification demand amount. Therefore, the amount of hypochlorous acid released into the living room 2 can be increased more than in the first control mode.

As described above, in the space purification device 40, the first control mode and the second control mode are combined to execute the humidification purification operation, thereby supplying a predetermined amount of hypochlorous acid to the living room 2 regardless of the season. can be discharged, and the cleanliness of the living room 2 can be maintained throughout the year.

As described above, according to the space purification device 40 according to the first embodiment, the following effects can be obtained.

(1) The space purification device 40 includes a micronization unit 41 that adds hypochlorous acid to the air introduced from the living room 2 by pumping up and centrifugally crushing the stored hypochlorous acid water, and the micronization unit 41. and a control unit 60 for controlling the rotation operation during centrifugal crushing. The control unit 60 controls the rotation speed of the miniaturization unit 41 based on the required amount of humidification to the living room 2, and the rotation of the miniaturization unit 41 based on the required amount of hypochlorous acid to the living room 2. and a second control mode for controlling the number of units, and the first control when the operation mode information transmitted from the air conditioner 13 for adjusting the temperature of the air introduced from the living room 2 to the atomization unit 41 indicates heating operation. mode, and when the operation mode information indicates cooling operation, the second control mode is executed.

According to this configuration, the first control mode is executed when the air conditioner 13 is in heating operation, that is, when the relative humidity in the living room 2 is low and the amount of humidification can be increased (for example, winter in Japan). On the other hand, the second control mode is executed when the air conditioner 13 is in cooling operation, that is, when the required amount of humidification to the living room 2 is small (for example, summer in Japan). As a result, in winter in Japan, the miniaturization unit 41 performs a rotation operation based on the required amount of humidification, so that the amount of hypochlorous acid released to the living room 2 can be easily adjusted according to the required amount of humidification. can be done. On the other hand, in summer in Japan, the miniaturization unit 41 performs a rotation operation based on the required amount of hypochlorous acid, so the amount of hypochlorous acid released to the living room 2 can be easily adjusted regardless of the required amount of humidification. can do. In other words, in the space purifier 40, the first control mode and the second control mode are combined to perform the humidifying and purifying operation, thereby facilitating adjustment of the amount of hypochlorous acid released into the air throughout the year. can.

(2) In the space purification device 40, the control unit 60 controls the set temperature of the living room 2 (set temperature of the living room) and the outside air temperature outside the living room 2 when the operation mode information of the air conditioner 13 indicates the heating operation. When the temperature difference between is below the reference temperature (for example, 6° C.), the second control mode is executed. As a result, in a situation where the heating operation of the air conditioner 13 is substantially stopped, the rotation operation based on the hypochlorous acid demand amount is performed in the miniaturization unit 41, so that a predetermined amount of hypochlorous acid in the living room 2 The release amount of hypochlorous acid to the living room 2 can be adjusted without creating a situation in which acid is difficult to release.

(3) In the space purification device 40, the controller 60 executes the second control mode when the operation mode information indicates that the operation of the air conditioner 13 is to be stopped. As a result, during periods when air conditioning is not required for the living room 2 (for example, during the transition period between summer and winter in Japan), the miniaturization unit 41 performs the rotation operation based on the hypochlorous acid demand amount. Therefore, the release amount of hypochlorous acid to the living room 2 can be adjusted without causing a situation in which a predetermined amount of hypochlorous acid is difficult to be released into the living room 2. - 特許庁

In the space purification device 40 according to the present embodiment, when the humidity in the living room 2 becomes equal to or higher than the reference humidity (for example, relative humidity 80%) during the rotation operation in the second control mode, the control unit 60 It may be controlled to switch to the rotation operation in the first control mode. As a result, the amount of humidification associated with the release of hypochlorous acid into the living room 2 can be adjusted so that the living room 2 is not over-humidified.

Further, in the space purification device 40 according to the present embodiment, the miniaturization unit 41 is configured to control the stop state and the drain state of the hypochlorous acid water stored in the mixing tank 42 by rotating the pumping pipe 43a. However, it is not limited to this. For example, the atomization unit 41 may use a general drainage mechanism (for example, a drainage valve) to control the water stop state and the drainage state of the hypochlorous acid water stored in the mixing tank 42 . However, in this case, it is necessary to replace the lower limit rotation speed in the first control mode with 0 rpm. With such a configuration, the above effects can also be enjoyed.

The space purification device according to the present invention can easily adjust the amount of hypochlorous acid released into the air when the hypochlorous acid water is atomized and the hypochlorous acid is released into the air. It is useful as a device for sterilizing or deodorizing the air in the target space.
