If electrolysis is carried out while the water to be electrolyzed is dirty, dirt may adhere to the electrodes for electrolysis, shortening the life of the electrodes. Further, the electrolyzed water spraying device is provided with a filter, and if the filter becomes dirty due to long-term use, the electrolyzed water will not be sprayed sufficiently, so a display is provided to prompt maintenance. Since these displays are made at independent timings, after the user has drained the water by the display prompting the user to drain the water, the display prompting maintenance may be immediately displayed, which reduces the user's convenience.

The present disclosure has been made to solve the above problems, and aims to provide a technology that improves the user's convenience regarding maintenance of the electrolyzed water spraying device.

In order to solve the above-described problems, an electrolyzed water spraying device according to an aspect of the present disclosure is an electrolyzed water spraying device for spraying electrolyzed water, comprising: a water storage unit for storing water; a water level detection unit for detecting the water level in the water storage unit; an electrolysis unit for generating electrolyzed water by electrolyzing water in the water storage unit; Prepare. The control unit includes: a first measurement unit that measures a first period during which the water level detected by the water level detection unit indicates that there is water; a second measurement unit that measures a second period during which the control unit is energized; When the operation unit is operated, the first measurement unit resets the first period, and the second measurement unit resets the second period.

It should be noted that any combination of the above-described components and expressions of the present disclosure converted between methods, devices, systems, recording media, computer programs, etc. are also effective as aspects of the present disclosure.

ADVANTAGE OF THE INVENTION According to this indication, the user's convenience regarding maintenance of an electrolyzed water spraying apparatus can be improved.

Before specifically describing the embodiments of the present disclosure, an overview of the embodiments will be described. This embodiment relates to an electrolyzed water spraying device that generates electrolyzed water using water stored in a water storage unit and then sprays the electrolyzed water. The electrolyzed water spraying device measures a period (hereinafter referred to as a "first period") after determining that there is water in the water reservoir, and recognizes that it is time to drain water when the first period is equal to or greater than a first threshold value. On the other hand, the electrolyzed water spraying device measures a period (hereinafter referred to as a "second period") after energization, and recognizes that it is time to clean the filter or the like when the second period exceeds a second threshold value. As described above, when the display for urging drainage is made at the timing of draining and the display for urging maintenance at the timing of maintenance, a situation arises in which the two displays are made with only a short interval between them, which lowers the user's convenience.

In order to suppress the occurrence of such a situation, the electrolyzed water spraying apparatus according to the present embodiment displays a display prompting maintenance when the first period exceeds the first threshold value or when the second period exceeds the second threshold value. In addition, the electrolyzed water spraying device resets the first period and the second period after the display for prompting maintenance. In other words, the electrolyzed water spraying apparatus compares the first period and the first threshold value and the second period and the second threshold value in parallel, while sharing the reset timing and the display, thereby suppressing the occurrence of a situation in which the two displays are performed only at short intervals.

Hereinafter, embodiments for implementing the present disclosure will be described with reference to the accompanying drawings. 1(a) and 1(b) show the structure of the electrolytic water spraying device 100. FIG. FIG. 1(a) is a perspective view of the electrolyzed water spraying device 100, and is a front view of the electrolyzed water spraying device 100. FIG. FIG. 1(b) is a perspective view of the electrolyzed water spraying device 100, and is a front view of the electrolyzed water spraying device 100 with the panel 3 of FIG. 1(a) opened. The electrolyzed water spraying device 100 includes a substantially box-shaped main body case 1 , and has substantially rectangular intake ports 2 on both side surfaces of the main body case 1 . An openable air outlet 6 is provided on the top surface of the main body case 1 . In FIGS. 1(a) and 1(b), the outlet 6 is in a closed state.

A top panel 20 is provided on the front side of the top surface of the body case 1 . 2(a) and 2(b) show the structure of the top panel 20 and the inner door panel 25. FIG. FIG. 2A is a schematic diagram schematically showing the top panel 20. FIG. The top panel 20 is provided with a plurality of lamps for indicating the state of the electrolyzed water spraying device 100 and giving various instructions to the user depending on the lighting state, one of which is the notification lamp 122. Notification lamp 122 lights up when there is some notification. The top panel 20 is also provided with a power button 120 that is pushed down when the power of the electrolyzed water spraying device 100 is turned on/off. FIG. 2(b) will be described later, returning to FIGS. 1(a)-(b).

An openable and closable panel 3 is provided on a main body side surface 1A, which is the right side surface (one side surface of the main body case 1) when viewed from the front side of the main body case 1. As shown in FIG. The panel 3 is provided with an air intake port 2 on one side surface of the main body case 1 . When the panel 3 is opened, a vertically long rectangular opening 4 appears. From the opening 4, a water storage part 14, a water supply part 15, a tablet insertion case 18a, etc., which will be described later, are arranged. These are removable.

A door inner panel 25 that can be operated by the user through the opening 4 is provided in the main body case 1 . FIG. 3(b) is a schematic diagram schematically showing the inner door panel 25. As shown in FIG. The door inner panel 25 is provided with a plurality of lamps for indicating the state of the electrolyzed water spraying device 100 and giving various instructions to the user depending on the lighting state, one of which is the display unit 111. The display unit 111 displays a notice to prompt maintenance of the electrolyzed water spraying device 100 . For example, when maintenance of the electrolyzed water spraying device 100 is required, the notification lamp 122 on the top panel 20 is lit. After confirming that the notification lamp 122 is turned on, the user opens the panel 3 and confirms that the display unit 111 is turned on, thereby recognizing that the electrolyzed water spraying device 100 needs maintenance.

Further, the inner door panel 25 is provided with a plurality of operation buttons for the user to give various notifications to the electrolyzed water spraying device 100 , one of which is the operation unit 112 . The operation unit 112 is an operation button for notifying the electrolyzed water spraying device 100 that maintenance has been performed after the user drains the water storage unit 14 or cleans a filter (not shown), which will be described later, when the display unit 111 displays a message to prompt maintenance of the electrolyzed water spraying device 100. This corresponds to a button to be operated when maintenance of the electrolyzed water spraying device 100 is performed. When the operation unit 112 is operated by the user, the electrolyzed water spraying device 100 recognizes that maintenance has been completed, and ends the display of the notification lamp 122 and the display unit 111 . Return to FIG. 1(b).

As described above, the water reservoir 14 can be removed from the opening 4 that appears when the panel 3 is opened, and the water is drained by removing the water reservoir 14 from the opening 4 . The filter can also be taken out from an opening 4 that appears when the panel 3 is opened, and the water reservoir 14 is taken out from the opening 4 and cleaned. The operation unit 112 is provided at a position where operation cannot be performed unless the panel 3 is opened. As a result, when notification is given by the notification lamp 122, the user must open the panel 3 in order to end the display. Therefore, the electrolyzed water spraying device 100 can prompt the user to drain the water storage section 14 or clean the filter through the operation of opening the panel 3 . Also, when operating the display unit 111 , the user can confirm the state of the water storage unit 14 through the opening 4 . Thereby, the user can operate the operation unit 112 after visually confirming that the water storage unit 14 is being drained.

3(a) and 3(b) are sectional views showing the structure of the electrolyzed water spraying device 100. FIG. In particular, FIG. 3(a) is a longitudinal cross-sectional view of the central portion of the electrolyzed water spraying device 100 in a front view, and is a view of the electrolyzed water spraying device 100 as seen from the right side. FIG. 3(b) is a longitudinal cross-sectional view of the right side of the electrolyzed water spraying device 100 viewed from the front, and is a view of the electrolyzed water spraying device 100 as seen from the right side. FIG. 4 is a functional block diagram of the electrolyzed water spraying device 100. As shown in FIG.

As shown in FIGS. 1(b), 3(a)-(b), and 4, the body case 1 is provided with an electrolyzed water generator 5, a water supply unit 15, a sprayer 19, and an air passage 8. The electrolyzed water generating unit 5 includes a water storage unit 14 , an electrolysis unit 17 , an electrolysis promoting tablet input unit 18 , a control unit 30 and a display unit 111 . The water storage part 14 has a box shape with an open top surface, and has a structure capable of storing water. The water storage part 14 is arranged in the lower part of the main body case 1 , can be horizontally slid from the main body case 1 and can be removed from the main body case 1 , and can be taken out from the opening 4 . The water storage unit 14 stores water supplied from the water supply unit 15 .

The electrolyzer 17 is provided with an electrode member (not shown), which is installed so as to be submerged in the water in the reservoir 14 . By energizing the electrode member, the electrolyzer 17 electrochemically decomposes the water containing chloride ions in the water reservoir 14 to generate electrolyzed water containing active oxygen species. Here, the active oxygen species refer to oxygen molecules having higher oxidation activity than normal oxygen and their related substances. For example, active oxygen species include so-called narrowly defined active oxygen such as superoxide anions, singlet oxygen, hydroxyl radicals, or hydrogen peroxide, and so-called broadly defined active oxygen such as ozone and hypochlorous acid (hypohalous acid).

The electrolyzing unit 17 repeats one cycle a plurality of times of the energization time for energizing the electrode member for electrolysis and the time after the energization is stopped, that is, the non-energization time, which is the time during which the energization is not performed, to generate electrolyzed water. By providing non-energization time for the electrode member, the life of the electrode member is extended. If the energization time is longer than the non-energization time, electrolyzed water containing a larger amount of active oxygen species is produced per cycle. Also, if the non-energization time is made longer than the power-on time, the generation of reactive oxygen species per cycle can be suppressed. Furthermore, by increasing the amount of electric power during the energization time, electrolyzed water containing a larger amount of active oxygen species is produced.

The electrolysis promoting tablet loading unit 18 includes a tablet loading case 18a, a tablet loading member (not shown) provided in the tablet loading case 18a, and a tablet loading cover 18b detachably provided on the top of the tablet loading case 18a. The tablet insertion case 18a can be taken out from the opening 4. As shown in FIG. By removing the tablet charging cover 18b from the taken-out tablet charging case 18a, the user can load the electrolysis enhancing tablets into the tablet charging case 18a.

The electrolysis-enhancing tablet input unit 18 rotates the tablet input member when receiving an instruction to input an electrolysis-enhancing tablet from the control unit 30 . When the tablet loading member rotates, the electrolysis-enhancing tablet drops into the reservoir 14 through a drop opening (not shown) in the bottom of the tablet loading case 18a. The electrolysis-enhancing tablet input unit 18 counts the number of electrolysis-enhancing tablets dropped from the tablet-input case 18a into the water storage unit 14, and when it is determined that one electrolysis-enhancing tablet has dropped from the tablet-input case 18a into the water storage unit 14, the tablet input member stops rotating. By dissolving the electrolysis-promoting tablets in the water in the water storage part 14, the water in the water storage part 14 contains chloride ions. An example of an electrolysis enhancing tablet is sodium chloride.

The electrolyzed water spraying device 100 may not have the electrolysis-enhancing tablet input section 18 . In this case, the electrolyzed water spraying device 100 may notify the user to insert the electrolysis-enhancing tablet by display or sound, and the user may directly insert the electrolysis-enhancing tablet into the water reservoir 14 .

The controller 30 is provided, for example, on the back side of an operation panel provided on the top surface of the main body case 1 (see FIG. 1), and controls the electrolyzed water generator 5 . Specifically, the control unit 30 controls electrolysis of water by the electrolysis unit 17 . Also, the control unit 30 controls display on the display unit 111 .

The water supply unit 15 is installed on the right side surface of the inside of the main body case 1 when viewed from the front, is detachable from the water storage unit 14 , and can be taken out from the opening 4 . The water supply portion 15 is attached to a tank holding portion 14 a provided on the bottom surface of the water storage portion 14 . The water supply unit 15 includes a tank 15a for storing water, and a lid 15b provided at an opening (not shown) of the tank 15a. An opening/closing part (not shown) is provided in the center of the lid 15b.

Specifically, when the opening of the tank 15a faces downward and the water supply section 15 is attached to the tank holding section 14a of the water storage section 14, the opening and closing section is opened by the tank holding section 14a. That is, when the water supply unit 15 filled with water is attached to the tank holding unit 14a, the opening/closing unit is opened to supply water to the water storage unit 14, and the water storage unit 14 is filled with water. When the water level in the water storage part 14 rises and reaches the lid 15b, the opening of the water supply part 15 is water-sealed so that the water supply is stopped, the water remains inside the water supply part 15, and the water inside the tank 15a is supplied to the water storage part 14 each time the water level in the water storage part 14 drops. That is, the water level in the water reservoir 14 is kept constant.

The electrolyzed water spraying device 100 may not have the tank 15 a as the water supply unit 15 . In this case, the line for supplying water to the electrolyzed water spraying device 100 is pulled from the tap water, and when the water level in the water reservoir 14 drops, tap water may be supplied until the water level in the water reservoir 14 rises to a predetermined position.

The spraying section 19 includes an air blowing section 7 and a filter section 16 . The air blowing section 7 is provided in the central portion of the main body case 1 and includes a motor section 9, a fan section 10 rotated by the motor section 9, and a scroll-shaped casing section 11 surrounding them. The motor section 9 is fixed to the casing section 11 .

The fan section 10 is a sirocco fan and is fixed to a rotating shaft 9 a extending horizontally from the motor section 9 , and the motor section 9 is fixed to the casing section 11 . A rotating shaft 9 a of the motor portion 9 extends from the front side of the body case 1 to the back side thereof. The casing portion 11 has a discharge port 12 on the upper surface side of the main body case 1 of the casing portion 11 and a suction port 13 on the back side of the main body case 1 of the casing portion 11 . The air volume of the air blower 7 is determined for each air volume unit time (for example, 5 minutes) according to the temperature, humidity, and gas odor level. The amount of rotation of the motor section 9 is controlled based on the determined air volume.

The filter part 16 is a member that brings the electrolyzed water stored in the water storage part 14 into contact with the indoor air that has flowed into the main body case 1 by the blower part 7 . The filter unit 16 is configured in a cylindrical shape, and a filter 16a having holes through which air can flow is arranged on the circumference thereof, and one end of the filter is immersed in the electrolyzed water stored in the water storage unit 14, and is rotatably built in the water storage unit 14 about the central axis of the filter 16a as a rotation center so that the water is retained. The filter unit 16 is rotated by a driving unit (not shown) to bring the electrolyzed water and the room air into continuous contact.

The air passage 8 connects the intake port 2 and the blowout port 6 , and includes a filter portion 16 , a blower portion 7 , and a blowout port 6 in order from the intake port 2 . When the fan portion 10 is rotated by the motor portion 9, the external air sucked from the intake port 2 and entering the air passage 8 is blown out of the electrolyzed water spraying device 100 through the filter 16a, the blower portion 7, and the blowout port 6 in order. Thereby, the electrolyzed water generated in the water storage part 14 is sprayed to the outside. The electrolyzed water spraying device 100 does not necessarily have to spray the electrolyzed water itself, and even if the electrolyzed water-derived (including volatilized) active oxygen species generated as a result is sprayed, it is included in electrolyzed water spraying.

FIG. 5 is a perspective view showing the structure of the water reservoir 14. As shown in FIG. The water storage section 14 includes a first water storage section 34 , a second water storage section 35 , a partition plate 36 and communication holes 37 . The first water storage section 34 is a section in which the electrolysis section 17 and the opening/closing section of the water supply section 15 are arranged. In FIG. 5, it is the right partition. Water is supplied into the first water storage compartment 34 from the opening/closing part. The second water storage section 35 is a section in which the filter 16a and the filter portion 16 are arranged. In FIG. 4, it is the left section.

The partition plate 36 is a plate that partitions the first water storage compartment 34 and the second water storage compartment 35 . The partition plate 36 extends upward from the bottom surface of the water reservoir 14, and the upper end of the partition plate 36 is arranged above the water surface. The communication hole 37 is a laterally long opening and is arranged at the lower end of the partition plate 36 . The communication hole 37 communicates between the first water storage section 34 and the second water storage section 35 . Water in the first water storage compartment 34 flows into the second water storage compartment 35 via the communication hole 37 . The bottom surface of the first water storage compartment 34 and the bottom surface of the second water storage compartment 35 are arranged on the same plane.

In the second water storage section 35 and around the second water storage section 35, a first detection section and a second detection section, which are water level detection sections to be described later, are arranged. The first detection section detects the maximum amount of water required to be stored in the water storage section 14 . The first detection unit includes a float portion 40a having buoyancy, a magnet 41a provided on the float portion 40a, and a detection portion (not shown) for detecting the position of the magnet 41a provided on the float portion 40a. The float portion 40 a is arranged within the second water storage compartment 35 , and the sensing portion is arranged outside the water storage section 14 around the second water storage compartment 35 , that is, in the body case 1 . When the float portion 40a floats to a first predetermined height corresponding to the maximum amount of water required, the first sensing portion senses the magnet 41a provided on the first float portion 40a and sends a first signal to the control section 30.

The second detection section detects the minimum amount of water required to be stored in the water storage section 14 . The second detection unit includes a float portion 40b having buoyancy, a magnet 41b provided on the float portion 40b, and a detection portion (not shown) for detecting the position of the magnet 41b provided on the float portion 40b. The float portion 40 b is arranged within the second water storage compartment 35 , and the sensing portion is arranged outside the water storage section 14 around the second water storage compartment 35 , that is, in the body case 1 . When the minimum amount of water or more is stored in the water reservoir 14, the float portion 40b moves to a predetermined position due to buoyancy, and the detection portion detects the magnet 41b provided on the float portion 40b. However, when the water in the water storage part 14 decreases and the float part 40b lowers to a second predetermined height corresponding to the minimum required amount of water, the detection part can no longer detect the magnet 41b provided on the float part 40b and sends a second signal to the control part 30.

FIG. 6 is a functional block diagram of the control section 30. As shown in FIG. Control unit 30 includes first measurement unit 150 , second measurement unit 152 , and instruction unit 154 . Also, the control unit 30 is connected to the water storage unit 14 , the display unit 111 and the operation unit 112 . Water storage unit 14 includes water level detection unit 140 . The water level detection unit 140 includes the above-described first detection unit and second detection unit, and detects the water level in the water storage unit 14 by the first detection unit and the second detection unit. As described above, the first detection unit detects whether or not the water level exists up to the first predetermined height corresponding to the required maximum amount of water, and the second detection unit detects whether or not the water level exists up to the second predetermined height corresponding to the required minimum amount of water. Further, when the water level is equal to or higher than the first predetermined height, the first detection unit transmits the first signal, and when the water level is equal to or lower than the second predetermined height, the second detection unit transmits the second signal. If the water level is between the first predetermined height and the second predetermined height, neither the first nor the second signal is transmitted.

The first measurement unit 150 measures the period during which the first signal is received from the water level detection unit 140 as the first period. Receiving the first signal from the water level detector 140 corresponds to indicating that there is water in the water level. The first measurement unit 150 is composed of a counter, and counts up when it continues to receive the first signal. Here, when the first measurement unit 150 stops receiving the first signal and resumes receiving the first signal, it restarts counting up from the previous count value. That is, the first measurement unit 150 cumulatively adds the first period. The first measurement unit 150 sequentially outputs the count value, that is, the first period, to the instruction unit 154 .

The second measurement unit 152 measures a period during which the electrolyzed water spraying device 100 is supplied with power from a power outlet (not shown) as a second period. Power supply to the electrolyzed water spraying device 100 corresponds to energization of the control unit 30 . The second measurement unit 152 is composed of a counter, and counts up when the power continues to be turned on. Here, the second measuring unit 152 restarts counting up from the previous count value when the power is turned off from the on state and then turned on again. That is, the second measurement unit 152 cumulatively adds the second period. Second measurement unit 152 sequentially outputs the count value, that is, the second period to instruction unit 154 .

The instruction unit 154 receives the first period from the first measurement unit 150 and the second period from the second measurement unit 152 . The instruction unit 154 decides to display a notification prompting maintenance when the first period measured by the first measurement unit 150 is equal to or greater than a first threshold value, or when the second period measured by the second measurement unit 152 is equal to or greater than a second threshold value. Here, the first threshold value has a value corresponding to the period during which the water stored in the water reservoir 14 should be drained, and the second threshold value has a value corresponding to the period during which the filter 16a and the like should be cleaned. The first threshold and the second threshold may be determined based on experiments or operational results. When the instruction unit 154 decides to display a notification to prompt maintenance, the instruction unit 154 causes the display unit 111 to display the notification.

As described above, after the notification is displayed on the display unit 111, the operation unit 112 is operated by the user when maintenance such as draining the water storage unit 14 and cleaning the filter 16a is performed by the user. When the operation unit 112 is operated, the first measurement unit 150 resets the first period, and the second measurement unit 152 resets the second period. This corresponds to resetting the counters in the first measurement unit 150 and the second measurement unit 152 . Subsequently, the first measuring unit 150 starts measuring in the first period, and the second measuring unit 152 starts measuring in the second period.

The subject of an apparatus, system, or method in this disclosure comprises a computer. The main functions of the device, system, or method of the present disclosure are realized by the computer executing the program. A computer has a processor that operates according to a program as its main hardware configuration. Any type of processor can be used as long as it can implement functions by executing a program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or LSI (Large Scale Integration). A plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. A plurality of chips may be integrated into one device, or may be provided in a plurality of devices. The program is recorded in a non-temporary recording medium such as a computer-readable ROM, optical disk, hard disk drive, or the like. The program may be pre-stored in a recording medium, or may be supplied to the recording medium via a wide area network including the Internet.

The operation of the electrolyzed water spraying device 100 configured as above will be described. FIG. 7 is a flow chart showing a control procedure by the control unit 30. As shown in FIG. The first measurement unit 150 measures the first period (S10), and the second measurement unit 152 measures the second period (S12). If the first period is greater than or equal to the first threshold value (Y of S14), the instruction unit 154 causes the display unit 111 to display a notification (S18). If the first period is not equal to or greater than the first threshold (N of S14) and the second period is not equal to or greater than the second threshold (N of S16), the process returns to step 10. If the second period is equal to or greater than the second threshold (Y of S16), the instruction unit 154 causes the display unit 111 to display the notification (S18). If there is no operation on the operation unit 112 (N of S20), the process returns to step 18. FIG. If there is an operation on the operation unit 112 (Y of S20), the first measurement unit 150 resets the first period, and the second measurement unit 152 resets the second period (S22).

According to this embodiment, when the first period is equal to or greater than the first threshold value, or when the second period is equal to or greater than the second threshold value, the notification is displayed on the display unit 111, so the notification can be displayed based on two different indicators. Since the notification is displayed based on two different indexes, the notification can be displayed based on the timing when the water reservoir 14 should be drained and the timing when the filter 16a should be cleaned. In addition, since one notification is displayed based on two different indicators, it is possible to prevent different notifications from being displayed at close timings. In addition, since different notifications are prevented from being displayed at close timing, the user's convenience regarding maintenance of the electrolyzed water spraying device 100 can be improved.

A summary of one aspect of the present disclosure is as follows. An electrolyzed water spraying device (100) according to an aspect of the present disclosure is an electrolyzed water spraying device (100) for spraying electrolyzed water, comprising a water storage part (14) for storing water, a water level detection part (140) for detecting the water level in the water storage part (14), an electrolysis part (17) for electrolyzing the water in the water storage part (14) to generate electrolyzed water, and a display part for displaying a notification prompting maintenance of the electrolyzed water spraying device (100). (111), an operation unit (112) to be operated when maintenance of the electrolyzed water spraying device (100) is performed, and a control unit (30) for controlling the display unit (111). The control unit (30) comprises a first measurement unit (150) that measures a first period in which the water level detected by the water level detection unit (140) indicates the presence of water, a second measurement unit (152) that measures a second period in which the control unit (30) is energized, and when the first period measured by the first measurement unit (150) is equal to or greater than the first threshold value, or when the second period measured by the second measurement unit (152) is equal to or greater than the second threshold value. and an instruction unit (154) for causing the display unit (111) to display the notification when the notification is received. When the operation unit (112) is operated, the first measurement unit (150) resets the first period, and the second measurement unit (152) resets the second period.

When the water level detected by the water level detection unit (140) indicates no water and the operation unit (112) is operated, the first measurement unit (150) may reset the first period, and the second measurement unit (152) may reset the second period.

The present disclosure has been described above based on the embodiments. This embodiment is an example, and those skilled in the art will understand that various modifications are possible in the combination of each component or each treatment process, and such modifications are within the scope of the present disclosure.

In this embodiment, when the operation unit 112 is operated, the first measurement unit 150 resets the first period, and the second measurement unit 152 resets the second period. However, not limited to this, for example, when the water level detected by the water level detection unit 140 indicates no water and the operation unit 112 is operated, the first measurement unit 150 resets the first period, and the second measurement unit 152 may reset the second period. The fact that the water level detected by the water level detector 140 indicates no water corresponds to receiving the second signal from the second detector. According to this modification, since the condition for resetting the first period and the second period is that the detected water level indicates no water, the first period and the second period can be reset when the water reservoir 14 is surely drained.
