In principle, the number, arrangement, orientation, shape, and size of the devices, instruments, and components that constitute the present invention are not limited to those shown in the following embodiments. The present invention can include all combinations of configurations that can be combined among the configurations disclosed in the following embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing an outline of the configuration of the cleaning apparatus 1 according to the first embodiment. The cleaning device 1 is a device that generates foam for cleaning an object. The cleaning apparatus 1 cleans the object by discharging the generated foam toward the object. The objects to be cleaned by the cleaning device 1 are, for example, tableware and cooking utensils.

  The foam in the present disclosure is a cream-like product formed by a collection of a large number of bubbles. Creamy foam is also called, for example, a foam. Foam is generated from a mixture of water and detergent. Detergents include, for example, surfactants.

  As illustrated in FIG. 1, the cleaning device 1 includes, for example, a detergent water storage unit 2, a water supply unit 3, a detergent supply unit 4, a bubble supply unit 5, a discharge unit 6, and a drainage unit 7.

  The detergent water storage unit 2 is a member for storing detergent water. The detergent water storage unit 2 is formed so as to be able to store water, detergent water, and foam generated on the surface of the detergent water. The detergent water storage unit 2 is, for example, a cylindrical container. The cylindrical detergent water storage part 2 is provided so that the longitudinal direction of the detergent water storage part 2 is a vertical direction. The shape of the cross section of the detergent water storage unit 2 is, for example, a circle, a square, a rectangle, or a pentagon or more polygon.

  A detergent water storage space 2 a and a foam storage space 2 b are formed inside the detergent water storage unit 2. The detergent water storage space 2a is a space in which detergent water is stored. The foam storage space 2b is a space in which foam generated on the surface of the detergent water in the detergent water storage space 2a is stored. The foam storage space 2b is arranged above the detergent water storage space 2a.

  The water supply unit 3 is for supplying water to the detergent water storage unit 2. The water supply unit 3 includes a water supply pipe 3a and a first electromagnetic valve 3b. A flow path for supplying water to the detergent water storage unit 2 is formed inside the water supply pipe 3a. In the present embodiment, an entrance / exit 2 c is formed at the bottom of the detergent water reservoir 2. One end of the water supply pipe 3a is connected to the entrance / exit 2c. The flow path inside the water supply pipe 3a communicates with the detergent water storage space 2a through the entrance / exit 2c. The other end of the water supply pipe 3a is connected to a water source such as a water supply.

  The first electromagnetic valve 3b is attached to the water supply pipe 3a. The 1st electromagnetic valve 3b is an apparatus for opening and closing the flow path inside the water supply pipe 3a. When the first electromagnetic valve 3b is opened, water is supplied from the water source to the detergent water storage space 2a. When the first electromagnetic valve 3b is closed, the supply of water from the water source to the detergent water storage space 2a is stopped.

  The detergent supply unit 4 is for supplying detergent to the detergent water storage unit 2. The detergent supply unit 4 includes, for example, a tank 4a, a detergent supply pipe 4b, and a second electromagnetic valve 4c. The tank 4a is a container-like member that stores a detergent. The detergent supply pipe 4 b is a member that connects the tank 4 a and the detergent water storage unit 2. A flow path for supplying the detergent stored in the tank 4a to the detergent water storage unit 2 is formed inside the detergent supply pipe 4b. The second electromagnetic valve 4c is attached to the detergent supply pipe 4b.

  In the present embodiment, a detergent supply port 2 d is formed in the upper part of the detergent water reservoir 2. As an example, the tank 4 a is disposed above the detergent water storage unit 2. One end of the detergent supply pipe 4b is connected to the detergent supply port 2d. The other end of the detergent supply pipe 4b is connected to the tank 4a. The flow path inside the detergent supply pipe 4b communicates with the inside of the tank 4a. The flow path inside the detergent supply pipe 4b communicates with the foam storage space 2b via the detergent supply port 2d.

  When the second electromagnetic valve 4c is opened, the detergent stored in the tank 4a is supplied to the foam storage space 2b. The detergent supplied to the foam storage space 2b is guided to the detergent water storage space 2a by its own weight. When the second electromagnetic valve 4c is closed, the supply of detergent from the tank 4a to the foam storage space 2b is stopped.

  In this way, water and detergent are supplied to the detergent water storage space 2a. The water and the detergent supplied to the detergent water storage space 2a are mixed to become detergent water. In the present embodiment, the detergent water is supplied to the detergent water storage space 2a by controlling the first solenoid valve 3b and the second solenoid valve 4c. The water supply unit 3 and the detergent supply unit 4 in the present embodiment are an example of a detergent water supply unit that supplies detergent water to the detergent water storage unit 2.

  In addition, the structure of the detergent water supply means which supplies detergent water is not restricted to the example mentioned above. For example, the detergent supply port 2d may be formed in the lower part of the detergent water storage unit 2 or the like. Moreover, the flow path inside the detergent supply pipe 4b may communicate with the detergent water storage space 2a. The cleaning device 1 may not include the detergent supply unit 4. For example, the detergent water storage unit 2 may be formed to be manually opened and closed. The detergent may be manually supplied into the detergent water storage unit 2 by the user. Similarly, water or detergent water may be manually supplied into the detergent water storage unit 2 by the user.

  Moreover, the bubble supply part 5 is an example of the bubble supply means which supplies the bubble for producing | generating a foam. The bubble supply unit 5 includes, for example, a bubble generator 5a, a pump 5b, and a circulation unit 5c. The bubble generator 5a is a device that generates bubbles in the liquid. The pump 5b is a device that flows liquid. The circulation part 5c is a tubular member. A flow path is formed inside the circulation part 5c.

  In the present embodiment, a first opening 2 e and a second opening 2 f are formed in the lower part of the detergent water storage unit 2. The first opening 2e and the second opening 2f are openings that communicate with the detergent water storage space 2a. As an example, one of the first opening 2e and the second opening 2f is above the other. In the present embodiment, the first opening 2e is formed above the second opening 2f as shown in FIG. For example, the center of the first opening 2e is above the center of the second opening 2f. For example, the lower end of the first opening 2e is above the upper end of the second opening 2f.

  The arrangement of the first opening 2e and the second opening 2f is not limited to the above example. The first opening 2e may be formed below the second opening 2f. Further, the vertical position of the first opening 2e and the vertical position of the second opening 2f may be the same.

  One end of the circulation part 5c is connected to the first opening 2e. The inside of the circulation part 5c communicates with the detergent water storage space 2a through the first opening 2e. The other end of the circulation part 5c is connected to the second opening 2f. The inside of the circulation part 5c communicates with the detergent water storage space 2a through the second opening 2f.

  That is, in this Embodiment, the inside of the detergent water storage part 2 and the inside of the circulation part 5c are connected via the 1st opening 2e and the 2nd opening 2f. When the detergent water is stored in the detergent water storage unit 2, the detergent water is also stored in the circulation unit 5 c communicating with the detergent water storage unit 2. Thus, the circulation part 5c is formed so that detergent water can be stored therein. The detergent water storage part 2 and the circulation part 5c of this Embodiment are an example of the storage part which can store the detergent water which is a mixture of water and a detergent inside.

  The bubble generator 5a and the pump 5b are provided in the middle of the circulation part 5c. The bubble generator 5a is disposed, for example, between the second opening 2f and the pump 5b. The pump 5b is disposed between the first opening 2e and the bubble generator 5a. In the present embodiment, the pump 5b generates a water flow from the first opening 2e toward the second opening 2f inside the circulation unit 5c.

  When the pump 5b is operated, the detergent water stored in the detergent water storage space 2a flows into the circulation part 5c from the first opening 2e. The detergent water that has flowed from the first opening 2e into the flow path inside the circulation part 5c passes through the pump 5b and the bubble generator 5a. The detergent water that has passed through the bubble generator 5a is returned to the detergent water storage space 2a through the second opening 2f. In this way, the detergent water stored in the detergent water storage space 2a circulates in the circulation part 5c when the pump 5b operates.

  The bubble generator 5a is a device that generates bubbles in the detergent water by introducing gas into the detergent water flowing through the flow path inside the circulation portion 5c. The bubble generator 5a takes in air from the outside of the cleaning device 1, for example. The bubble generator 5a introduces the taken-in air into the detergent water flowing through the flow path inside the circulation unit 5c. Thereby, bubbles are generated in the detergent water. The detergent water containing bubbles is returned to the detergent water storage space 2a from the second opening 2f.

  In this way, the bubble supply unit 5 supplies bubbles for generating foam into the detergent water storage unit 2. The 2nd opening 2f in this Embodiment is an example of the bubble supply port for supplying the bubble for producing | generating a foam to the inside of the detergent water storage part 2. FIG. As described above, the inside of the circulation part 5c communicates with the detergent water storage space 2a via the second opening 2f which is an example of the bubble supply port. In the present embodiment, the pump 5b and the bubble generator 5a generate a water flow including bubbles from the second opening 2f toward the detergent water storage space 2a.

  The bubble generator 5a has the following ejectors as a structure for generating bubbles. The ejector of the bubble generator 5a has a reduced diameter portion where the diameter of the flow path is gradually reduced. An intake port that communicates with the outside is formed in the reduced diameter portion. When the liquid flows through the reduced diameter portion, the pressure in the reduced diameter portion becomes negative. When the pressure in the reduced diameter portion becomes negative, gas is naturally sucked into the reduced diameter portion through the air supply port. For example, gas is sucked into the reduced diameter portion from a direction perpendicular to the flow of liquid flowing through the reduced diameter portion. The bubble generator 5a having an ejector generates bubbles in the liquid by supplying gas sucked from the outside to the liquid.

  When the bubble generator 5a has an ejector, it is preferable that a fixed wing is provided at a position upstream of the ejector. The fixed wing swirls the liquid flowing in the ejector. By providing the fixed wing upstream of the ejector, finer and more bubbles can be generated.

  In addition, the bubble generator 5a may have things other than said ejector as a structure which generates a bubble. For example, the bubble generator 5a may include an air pump that forcibly supplies gas to the detergent water flowing through the flow path inside the circulation unit 5c. Moreover, the bubble generator 5a may have a porous body that releases a gas into a liquid. The bubble generator 5a may be a device that generates bubbles by irradiating a liquid with ultrasonic waves. The bubble generator 5a may be a device that generates bubbles by stirring liquid with a motor or the like.

  FIG. 2 is a diagram schematically illustrating how foam is generated. As shown in FIG. 2, the bubbles supplied from the second opening 2f to the detergent water storage space 2a by the pump 5b and the bubble generator 5a are on the surface 100 of the detergent water stored in the detergent water storage space 2a. Surface. In addition, the detergent water around the bubbles rises with the rising bubbles. Thus, when bubbles are supplied to the detergent water storage space 2a by the pump 5b and the bubble generator 5a, an upward flow is generated in the detergent water storage space 2a.

  A large number of bubbles that have floated together with the detergent water gather on the liquid surface 100 which is a gas-liquid interface. A large number of bubbles collect to generate a foam. The foam that has begun to be generated rises above the liquid surface 100. Foam accumulates on the liquid surface 100 of the detergent water. The generated foam accumulates in the foam storage space 2b above the detergent water storage space 2a.

  In this way, the bubble generator 5a and the pump 5b generate foam on the surface of the detergent water stored in the detergent water storage space 2a. The bubble generator 5a and the pump 5b of the present embodiment are an example of foam generating means. The bubble generator 5a and the pump 5b generate bubbles in the detergent water storage unit 2 by generating a water flow including bubbles from the second opening 2f toward the detergent water storage space 2a.

  The operation for generating the foam is hereinafter referred to as “foam generation operation”. By continuing the foam generation operation, the foam continues to grow on the liquid surface 100. By continuing the foam generation operation, the foam storage space 2b is eventually filled with foam.

  The discharge unit 6 provided in the cleaning device 1 discharges the foam stored in the foam storage space 2b to the outside. The discharge unit 6 is formed in a nozzle shape, for example. A discharge port 6 a that is an opening for discharging foam is formed in the discharge unit 6. Inside the discharge part 6, the conveyance path 6b which is a flow path for conveying foam to the discharge port 6a is formed. The conveyance path 6b communicates with the discharge port 6a.

  In the present embodiment, a foam discharge port 2g is formed in the upper part of the detergent water storage unit 2. The foam discharge port 2g is an opening that communicates with the foam storage space 2b. As an example, the foam outlet 2g is formed above the first opening 2e and the second opening 2f.

  The discharge port 6 a is formed at one end of the discharge unit 6. As an example, the discharge port 6 a is disposed, for example, 50 mm or more above the lower end of the detergent water storage unit 2. The other end of the discharge unit 6 is connected to the foam discharge port 2g. The foam storage space 2b and the discharge port 6a communicate with each other via the foam discharge port 2g and the conveyance path 6b.

  When the foam generation operation described above is continued in the state where the foam storage space 2b is filled with foam, the foam is sent from the foam storage space 2b to the transport path 6b via the foam discharge port 2g. When the foam generation operation is continued, the foam is transported to the discharge port 6a through the transport path 6b. The foam conveyed to the discharge port 6a is discharged from the discharge port 6a to the outside of the cleaning device 1.

  When the user places the object under the discharge port 6a, the foam discharged from the discharge port 6a hits the object. The dirt attached to the object is removed by foam. Moreover, the foam adhering to the upper part of a target object moves to the lower part of the target object by gravity. When the foam moves on the surface of the object, shear stress, that is, shear stress acts on the dirt attached to the surface. For this reason, the cleaning apparatus 1 can efficiently remove the dirt attached to the object with a small amount of foam.

  In order to improve the usability of the cleaning device 1, it is desirable that the time from the start of the foam generation operation to the discharge of the foam is as short as possible. For example, the time can be shortened by increasing the amount of bubbles supplied by the bubble supply unit 5 per hour.

  The discharge port 6a is configured by a hole having a size such that bubbles forming the bubbles are not crushed and the bubbles can be smoothly discharged. The diameter of this hole is, for example, 10 mm or more in diameter. Further, a plurality of discharge ports 6 a may be formed in the discharge unit 6.

  The cross-sectional area of the conveyance path 6b is desirably as small as possible as long as the bubbles forming the bubbles are not crushed and the bubbles can move smoothly. By reducing the cross-sectional area of the conveyance path 6b, the volume of the entire conveyance path 6b is reduced. By reducing the volume of the transport path 6b, the time from the start of the foam generation operation until the foam is discharged is shortened.

  As shown in FIG. 1 as an example, the foam discharge port 2g is formed on a wall surface surrounding the foam storage space 2b from above. The foam discharge port 2g may be formed on a wall surface surrounding the foam storage space 2b from the side. Moreover, as an example, the discharge part 6 and the conveyance path 6b are formed in an arch shape as shown in FIG. The discharge part 6 and the conveyance path 6b may be formed along the vertical direction or the horizontal direction, for example. The discharge port 6 a of the discharge unit 6 may be above the upper end of the detergent water storage unit 2. Moreover, the discharge part 6 and the conveyance path 6b may be formed along the direction inclined with respect to the horizontal direction and the vertical direction.

  Further, the discharge unit 6 may be provided so as to be movable with respect to the detergent water storage unit 2. For example, the discharge unit 6 may be rotatable with respect to the detergent water storage unit 2. The discharge part 6 may be formed of a hard material. Moreover, the discharge part 6 may be a member which can be bent like a hose or a bellows tube. The discharge part 6 may be formed to be stretchable. The user can move the discharge port 6a close to the object by making the discharge unit 6 bendable or making the discharge unit 6 extendable and contractible. By providing the discharge unit 6 so as to be movable with respect to the detergent water storage unit 2, the usability of the cleaning device 1 is further improved.

  The drainage unit 7 provided in the cleaning device 1 is for discharging water, detergent water, and foam stored in the detergent water storage unit 2. The drainage unit 7 includes, for example, a drain pipe 7a and a third electromagnetic valve 7b. A flow path is formed in the drain pipe 7a. The third electromagnetic valve 7b is attached to the drain pipe 7a. The 3rd electromagnetic valve 7b is an apparatus for opening and closing the flow path in the drain pipe 7a.

  One end of the drain pipe 7 a communicates with the outside of the cleaning device 1. The other end of the drain pipe 7a is connected to the middle of the water supply pipe 3a between, for example, the entrance / exit 2c and the first electromagnetic valve 3b. That is, the drainage part 7 is connected to the detergent water storage part 2 through the water supply pipe 3a. The flow path in the drain pipe 7a communicates with the detergent water storage space 2a through the flow path in the water supply pipe 3a and the entrance / exit 2c.

  When the third electromagnetic valve 7b is opened, the water, detergent water and foam stored in the detergent water reservoir 2 are sent to the flow path in the drain pipe 7a via the flow path in the inlet / outlet 2c and the water supply pipe 3a. It is done. Water, detergent water and foam sent to the flow path in the drain pipe 7a are discharged to the outside of the cleaning device 1. The discharge of water, detergent water and foam stops when the third solenoid valve 7b is closed.

  In the present embodiment, as shown in FIG. 1, the joined water supply pipe 3 a and drain pipe 7 a are connected to the bottom of the detergent water storage unit 2. The configuration of the cleaning device 1 may be a configuration in which the water supply pipe 3a and the drain pipe 7a are separately connected to the detergent water storage unit 2 instead of the above configuration.

  Moreover, the washing | cleaning apparatus 1 is provided with the electrolyzed water production | generation part 20 as an example of an electrolyzed water production | generation means. The electrolyzed water generating unit 20 generates electrolyzed water by electrolyzing the liquid. The liquid electrolyzed by the electrolyzed water generating unit 20 includes at least one of water and detergent water. The liquid simply referred to as “detergent water” in the present disclosure is an electrolysis of a mixture of water and detergent before electrolysis, a mixture of water and detergent after electrolysis, and a mixture of water and detergent. Can include everything that has been done.

  The electrolyzed water generation unit 20 includes an electrode 21 and an ion adsorption electrode 22 as an example of an electrode for performing electrolysis. The electrolyzed water generating unit 20 has a power source 23 for flowing electricity to the electrode 21 and the ion adsorption electrode 22.

  The electrode 21 and the ion adsorption electrode 22 are disposed inside the detergent water reservoir 2. The electrode 21 and the ion adsorption electrode 22 are disposed so as to be immersed in the liquid when the liquid is stored in the detergent water storage unit 2. In this Embodiment, the electrode 21 and the ion adsorption electrode 22 are arrange | positioned in the detergent water storage space 2a. In addition, the electrode 21 and the ion adsorption electrode 22 may be arrange | positioned inside the circulation part 5c as an example other than this Embodiment.

  The electrode 21 is an example of a first electrode disposed inside the detergent water storage unit 2. The ion adsorption electrode 22 is an example of a second electrode arranged inside the detergent water storage unit 2. The electrode 21 and the ion adsorption electrode 22 face each other. As an example, the power source 23 is provided outside the detergent water storage unit 2.

  The electrode 21 and the ion adsorption electrode 22 are, for example, flat plate shapes. The length of the electrode 21 and the ion adsorption electrode 22 is, for example, about 10 [cm] to 30 [cm]. The thickness of the electrode 21 and the ion adsorption electrode 22 is, for example, about 5 [mm]. The width of the electrode 21 and the ion adsorption electrode 22 is, for example, about 5 [cm]. The plate-like electrode 21 and the ion adsorption electrode 22 are arranged along their thickness directions. The distance between the electrode 21 and the ion adsorption electrode 22 is, for example, about 5 [mm].

  Of the surface of the electrode 21, the surface facing the ion adsorption electrode 22 is an example of a first surface. Of the surface of the ion adsorption electrode 22, the surface facing the electrode 21 is an example of a second surface. That is, the first surface and the second surface face each other. The interval between the electrode 21 and the ion adsorption electrode 22 means the interval between the first surface and the second surface.

  The electrode 21 and the ion adsorption electrode 22 are each electrically connected to the power source 23. The electrode 21 electrolyzes the liquid when electricity flows through the electrode 21 by the power source 23. Further, the ion adsorption electrode 22 adsorbs ions in the liquid when electricity flows to the ion adsorption electrode 22 by the power source 23. The ion adsorption electrode 22 adsorbs ions unnecessary for electrolysis.

  The ion adsorption electrode 22 is formed of a metal material. The ion adsorption electrode 22 attracts cations in the liquid to electrons in the ion adsorption electrode 22. The ion adsorption electrode 22 attracts anions in the liquid to the protons in the ion adsorption electrode 22. For example, the ion adsorption electrode 22 adsorbs calcium ions contained in the liquid. By adsorbing calcium ions to the ion adsorption electrode 22, it is possible to prevent the scale mainly composed of calcium ions from being deposited on the surface of the electrode 21.

  As described above, the electrode 21 and the ion adsorption electrode 22 are disposed in the detergent water storage space 2a. That is, in the present embodiment, the two electrodes for performing electrolysis are arranged in the same space. The electrolyzed water generation unit 20 of the present embodiment performs electrolysis without requiring a diaphragm that separates the electrode 21 and the ion adsorption electrode 22. The electrolyzed water generating unit 20 is a single tank type device that generates electrolyzed water.

  The power source 23 can apply an AC voltage to the electrode 21. By switching between positive and negative voltages applied by the power source 23, the polarity of the electrode 21 to which the voltage is applied by the power source 23 is switched. The electrode 21 serving as an anode generates acidic electrolyzed water. Moreover, the electrode 21 which became a cathode produces | generates alkaline electrolyzed water. As described above, the single tank type electrolyzed water generation unit 20 can generate any one of acidic electrolyzed water and alkaline electrolyzed water by switching between positive and negative voltages applied by the power source 23.

  In addition, the cleaning device 1 includes, for example, a control device 8 and an operation unit 9. The control device 8 is an example of a control unit for controlling the operation of the cleaning device 1. The operation unit 9 is for the user to operate the cleaning device 1. The operation unit 9 includes, for example, buttons and switches that are operated by the user.

  The buttons constituting the operation unit 9 include, for example, a start button, a selection button, and a stop button. The start button is an example of a starting unit for starting the operation of the cleaning device 1. The selection button is an example of a selection unit for selecting polarity. The stop button is an example of a stop unit for stopping the operation of the cleaning device 1.

  FIG. 3 is a block diagram illustrating a control system of the cleaning apparatus 1 according to the first embodiment. The control device 8 and the operation unit 9 are electrically connected. The control device 8 is electrically connected to the first electromagnetic valve 3b, the second electromagnetic valve 4c, the third electromagnetic valve 7b, the pump 5b, and the power source 23. The control device 8 controls the first electromagnetic valve 3b, the second electromagnetic valve 4c, the third electromagnetic valve 7b, the pump 5b, and the power source 23. When the operation unit 9 is operated by the user, the control device 8 operates according to this operation.

  Moreover, the washing | cleaning apparatus 1 may be provided with the water level sensor 10 as an example of the detection means which detects the water level of the liquid in the detergent water storage part 2. FIG. The water level sensor 10 is electrically connected to the control device 8. As an example, the control device 8 may control the water supply unit 3 and the detergent supply unit 4 based on the detection result of the water level sensor 10 so that the liquid level 100 reaches a preset specified water level.

  The control device 8 may control the water supply unit 3 and the detergent supply unit 4 so that the water level detected by the water level sensor 10 is maintained at a preset specified water level. For example, the control device 8 may keep the water supply unit 3 and the detergent supply unit 4 supplying the detergent water to the detergent water storage unit 2 while the foam generation operation is being performed. As described above, the cleaning device 1 may be configured such that the water level detected by the water level sensor 10 is maintained at the preset specified water level while the foam generation operation is performed. The specified water level is set so that, for example, the entire electrode 21 is immersed in the liquid. Thereby, the state which can be electrolyzed by the electrode 21 is maintained.

  FIG. 4 is a diagram illustrating an example of a configuration of the control device 8 according to the first embodiment. The function of the control device 8 which is an example of the control means is realized by a processing circuit as shown in FIG. The processing circuit may be dedicated hardware 8a. The processing circuit may include a processor 8b and a memory 8c. A part of the processing circuit may be formed as dedicated hardware 8a, and the processing circuit may further include a processor 8b and a memory 8c. FIG. 4 shows an example in which a part of the processing circuit is formed as dedicated hardware 8a, and the processing circuit further includes a processor 8b and a memory 8c.

  The processing circuit, part of which is at least one dedicated hardware 8a, includes, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. .

  When the processing circuit includes at least one processor 8b and at least one memory 8c, the function of the control device 8 is realized by software, firmware, or a combination of software and firmware. Software and firmware are described as programs and stored in the memory 8c. The processor 8b implements each function by reading and executing a program stored in the memory 8c.

  The processor 8b is also referred to as a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. The memory 8c corresponds to, for example, a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM and an EEPROM, or a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a DVD.

  As described above, the processing circuit can realize the function of the control device 8 by hardware, software, firmware, or a combination thereof.

  As an example, the operation of the cleaning device 1 is controlled by a single control device 8. The operation of the cleaning device 1 may be controlled by a plurality of linked devices. That is, the cleaning device 1 may include a plurality of devices as control means. Moreover, the cleaning apparatus 1 may include a plurality of processing circuits for realizing the function of the control means.

  Next, the operation of the cleaning apparatus 1 will be described with further reference to FIG. FIG. 5 is a flowchart showing the operation of the cleaning apparatus 1 according to the first embodiment. It is assumed that the interior of the detergent water storage unit 2 is empty before the cleaning device 1 starts operating. At this time, the first electromagnetic valve 3b, the second electromagnetic valve 4c, and the third electromagnetic valve 7b are closed.

  For example, the cleaning device 1 starts operating when the user presses the start button of the operation unit 9. When the user presses the start button, the first electromagnetic valve 3b is opened by the control device 8 which is an example of the control means. By opening the first electromagnetic valve 3b, water is supplied from the water source to the detergent water storage unit 2 (step S101).

  As an example, when the water level detected by the water level sensor 10 reaches a preset water level, the control device 8 closes the first electromagnetic valve 3b. By closing the first electromagnetic valve 3b, water supply from the water source to the detergent water storage unit 2 is stopped. In addition, the time of the water supply to the detergent water storage part 2 stopping from a water source is not restricted to said example. For example, the control device 8 may close the first electromagnetic valve 3b when a predetermined time elapses after the first electromagnetic valve 3b is opened.

  After the water supply in step S <b> 101 is stopped, the control device 8 causes the power source 23 to apply a voltage to the electrode 21 and the ion adsorption electrode 22. By applying a voltage to the electrode 21 and the ion adsorption electrode 22, the water in the detergent water storage unit 2 is electrolyzed. Thereby, electrolyzed water is produced | generated. (Step S102).

  In the present embodiment, the user selects an arbitrary polarity by operating the selection button before or after pressing the start button of the operation unit 9. In step S102, the control device 8 controls the power supply 23 so that the polarity of the electrode 21 is the polarity selected by the user. As described above, the electrode 21 serving as the anode generates acidic electrolyzed water. The electrode 21 serving as a cathode generates alkaline electrolyzed water.

  After the electrolysis starts in step S102, the control device 8 opens the second electromagnetic valve 4c. The detergent is supplied to the detergent water storage unit 2 by opening the second electromagnetic valve 4c. As an example, the control device 8 closes the second electromagnetic valve 4c after a certain time has elapsed since the second electromagnetic valve 4c was opened. The predetermined time is set in advance so that a prescribed amount of detergent is supplied. In this way, a prescribed amount of detergent is supplied to the detergent water storage unit 2 (step S103).

  The detergent supplied to the detergent water reservoir 2 is mixed with the electrolyzed water in the detergent water reservoir 2 to become detergent water. The electrode 21 to which a voltage is applied from the power source 23 continues to electrolyze the detergent water. In this way, the detergent water in the detergent water reservoir 2 is electrolyzed. The control device 8 controls the power supply 23 so that the pH of the detergent water in the detergent water storage unit 2 becomes a specified value corresponding to the polarity selected by the user. As an example, the control device 8 stops the application of voltage to the power supply 23 after a predetermined time has elapsed since the application of voltage to the power supply 23 is started based on a preset program. When the power supply 23 stops applying the voltage, the electrolysis in the detergent water storage unit 2 stops.

  As described above, electrolytic water having a pH value corresponding to the polarity selected by the user is generated in the detergent water storage unit 2 through the above steps S101 to S103. This electrolyzed water contains a detergent component. In other words, electrolyzed water containing detergent components is generated in the detergent water storage unit 2 by the above steps S101 to S103.

  Note that the time point at which the power supply 23 stops applying the voltage is not limited to the above example. For example, a sensor that detects the pH of the liquid in the detergent water storage unit 2 may be provided in the detergent water storage unit 2. The control device 8 may stop the application of voltage to the power source 23 when the pH detected by the sensor reaches a specified value.

  Moreover, supply of the detergent to the detergent water storage unit 2 may be performed, for example, before water supply to the detergent water storage unit 2 is performed. That is, step S103 may be performed before step S101 is performed. Step S101 and step S103 may be performed simultaneously. Further, the electrolysis by the electrode 21 in step S102 may be performed after step S101 and step S103 are performed. The cleaning apparatus 1 may be configured to electrolyze water that does not include a detergent component, or may be configured to electrolyze detergent water that includes a detergent component.

  After the electrolyzed water containing the detergent component is generated in steps S101 to S103, the control device 8 starts the operation of the pump 5b (step S104). When the pump 5b is operated, the above-described foam generation operation is performed. When the foam generation operation is continued, the foam is discharged from the discharge port 6a. The user cleans the object with the foam discharged from the discharge port 6a.

  The user who is cleaning the object may switch the polarity of the electrode 21 by operating the selection button of the operation unit 9. That is, the user may switch the property of the foam discharged from the discharge port 6a from one of acidic and alkaline to the other by operating the selection button of the operation unit 9. As an example, after operating the pump 5b in step S104, the control device 8 determines whether a signal for switching the foam property from one of acidic and alkaline to the other is received from the selection button (step S105).

  When the user has not performed an operation to switch the foam property from one of acidic and alkaline to the other, the control device 8 continues the operation of the pump 5b. The user operates the stop button of the operation unit 9 when the cleaning of the object is completed. When this operation is performed, the control device 8 stops the operation of the pump 5b (step S106). Thereby, the foam generation operation ends. It should be noted that the time when step S106 is performed, that is, the time when the operation of the pump 5b stops is not limited to the time when the stop button is pressed. For example, the operation of the pump 5b may be automatically stopped after a certain time from the start.

  After stopping the pump 5b, the control device 8 opens the third electromagnetic valve 7b. By opening the third electromagnetic valve 7b, the detergent water and foam remaining in the detergent water storage unit 2 and the discharge unit 6 are discharged (step S107).

  Moreover, the button which comprises the operation part 9 in this Embodiment contains the rinse water production | generation button as an example. A user operates this rinse water production | generation button, when wanting to rinse the target object by the rinse water for the target object wash | cleaned with foam. Rinsing water is acidic or alkaline electrolyzed water produced by electrolyzing water that does not contain detergent components. That is, the rinse water is electrolyzed water that does not contain detergent components.

  After step S107, it is determined whether or not the rinse water generation button has been operated (step S108). For example, when the rinse water generation button is operated, a prescribed signal is transmitted from the operation unit to the control device 8. In step S108, the control device determines whether or not the above-mentioned prescribed signal has been received. When the rinse water generation button is not operated, a series of operations of the cleaning device 1 is completed as shown in FIG.

  When the control device 8 receives from the selection button a signal for switching the foam property from one of acidic and alkaline to the other in step S105, the control device 8 stops the operation of the pump 5b (step S110). The control device 8 opens the third electromagnetic valve 7b after stopping the operation of the pump 5b in step S110. When the third electromagnetic valve 7b is opened, the detergent water and foam remaining in the detergent water storage unit 2 and the discharge unit 6 are discharged (step S111).

  After the detergent water and foam are discharged in step S111, the control device 8 closes the third electromagnetic valve 7b and opens the first electromagnetic valve 3b. By opening the first electromagnetic valve 3b, water supply from the water source to the detergent water storage unit 2 is performed again (step S112). The water supply in step S112 is stopped when the water level detected by the water level sensor 10 reaches a preset water level, for example, as in step S101.

  After the water supply in step S112 is stopped, the control device 8 causes the power source 23 to apply a voltage to the electrode 21 and the ion adsorption electrode 22. Thereby, the water in the detergent water storage part 2 is electrolyzed and electrolyzed water is produced | generated. (Step S113). In step S113, the control device 8 controls the power supply 23 so that the polarity of the electrode 21 becomes the polarity after being switched by the user. The electrode 21 generates electrolyzed water having the other property described above, that is, the property after being switched by the user, by electrolysis.

  After the electrolysis starts in step S113, the control device 8 opens the second electromagnetic valve 4c. The detergent is supplied to the detergent water storage unit 2 by opening the second electromagnetic valve 4c. The detergent water storage unit 2 is supplied with a specified amount of detergent as in step S103 (step S114).

  The detergent supplied to the detergent water reservoir 2 is mixed with the electrolyzed water in the detergent water reservoir 2 to become detergent water. The electrode 21 to which a voltage is applied from the power source 23 continues to electrolyze the detergent water. In this way, the detergent water in the detergent water reservoir 2 is electrolyzed. The control device 8 controls the power supply 23 so that the pH of the detergent water in the detergent water storage unit 2 becomes a specified value, similarly to the above-described Step S102 and Step S103.

  As described above, electrolytic water containing detergent components is generated in the detergent water storage unit 2 through the above-described steps S112 to S114. The time point when the power supply 23 stops applying the voltage may be, for example, a time point when the pH detected by a sensor that detects the pH of the liquid in the detergent water storage unit 2 becomes a specified value.

  Step S114 may be performed before step S112 is performed. Step S112 and step S114 may be performed simultaneously. The electrolysis by the electrode 21 in step S113 may be performed after step S112 and step S114 are performed.

  After the electrolyzed water containing the detergent component is generated in steps S112 to S114, the control device 8 starts the operation of the pump 5b again (step S115). The foam generation operation is performed by operating the pump 5b. When the foam generation operation is continued, the foam is discharged from the discharge port 6a. The user cleans the object with the foam discharged from the discharge port 6a. Thus, the user of the cleaning apparatus 1 according to the present embodiment can clean the object with the other foam after washing the object with one of the acidic and alkaline foams.

  As described above, the user operates the stop button of the operation unit 9 when the cleaning of the object is completed. If this operation is performed after step S115, said step S106 will be implemented and foam production | generation operation | movement will be complete | finished.

  If it is determined in step S108 that the rinse water generation button has been operated, the control device 8 closes the third electromagnetic valve 7b and opens the first electromagnetic valve 3b. By opening the first electromagnetic valve 3b, water supply from the water source to the detergent water storage unit 2 is performed again (step S120).

  After the water supply in step S120 is started, the control device 8 causes the power source 23 to apply a voltage to the electrode 21 and the ion adsorption electrode 22. By applying a voltage to the electrode 21 and the ion adsorption electrode 22, the water in the detergent water storage unit 2 is electrolyzed and rinse water is generated. (Step S121).

  In the present embodiment, the user operates the selection button to select an arbitrary polarity before or after pressing the rinse water generation button of the operation unit 9. In step S121, the control device 8 controls the power source 23 so that the polarity of the electrode 21 is the polarity selected by the user. The electrode 21 that has become the anode in step S121 generates acidic rinse water. The electrode 21 that has become the cathode in step S121 generates alkaline rinse water.

  Rinsing water is discharged from the discharge port 6a by continuing the water supply from the water source to the detergent water storage unit 2 (step S122). The user rinses the object washed with foam with the rinsing water discharged from the discharge port 6a.

  For example, a user rinses an object washed with alkaline foam with acidic rinse water. Alkaline foam has a high ability to clean dirt containing protein adhering to an object. Moreover, the acidic rinse water can neutralize the alkaline foam adhering to the object. If it is this Embodiment, the foam after wash | cleaning a target object can be discharged | emitted after making it a neutral state. According to the present embodiment, an environmentally friendly cleaning device 1 can be realized.

  In addition, the user may rinse the object with alkaline rinsing water after washing the object with acidic foam. The user of the cleaning apparatus 1 of the present embodiment can discharge the kitchen foam after neutralizing the foam with alkaline rinse water after washing the kitchen sink scale with acidic foam, for example.

  The user operates the stop button of the operation unit 9 when the object has been rinsed with rinse water. When this operation is performed after step S122, the control device 8 stops the application of voltage to the power source 23, closes the first electromagnetic valve 3b, and opens the third electromagnetic valve 7b. When the third electromagnetic valve 7b is opened, the rinse water remaining in the detergent water storage unit 2 and the discharge unit 6 is discharged (step S123). When this step S123 is performed, a series of operations of the cleaning apparatus 1 is completed as shown in FIG.

  In addition, operation | movement of the washing | cleaning apparatus 1 shown with the flowchart of FIG. 5 is an example to the last. The operation of the cleaning apparatus 1 is not limited to that shown in FIG. For example, the cleaning device 1 may be configured to clean the inside of the detergent water storage unit 2 and the discharge unit 6 after step S107. The operation of cleaning the inside of the detergent water storage unit 2 and the discharge unit 6 is hereinafter referred to as a cleaning operation. The insides of the detergent water storage unit 2 and the discharge unit 6 are cleaned, for example, when the water supply unit 3 continues to supply water to the detergent water storage unit 2 and the discharge unit 6.

  If the water supply part 3 continues supplying water into the inside of the detergent water storage part 2 and the discharge part 6, the inside of the detergent water storage part 2 and the discharge part 6 will be filled with water soon. After the detergent water storage unit 2 and the discharge unit 6 are filled with water, the water is discharged from the discharge port 6a. In this way, the insides of the detergent water storage unit 2 and the discharge unit 6 are cleaned. Further, the water remaining after cleaning the inside of the detergent water storage unit 2 and the discharge unit 6 is drained by the drainage unit 7.

  The cleaning operation is performed as described above as an example. This cleaning operation for cleaning the insides of the detergent water storage unit 2 and the discharge unit 6 may be executed, for example, between the above step S111 and step S112.

  Further, the water supply in step S120 may be stopped when the water level detected by the water level sensor 10 reaches a preset water level, as in steps S101 and S112. In step S121, the control device 8 may control the power source 23 so that the pH of the rinse water in the detergent water storage unit 2 becomes a specified value corresponding to the polarity selected by the user. The cleaning device 1 may further include a device that discharges the rinsing water stored in the detergent water storage unit 2 from the discharge port 6a.

  Moreover, said step S111 and step S112 may be abbreviate | omitted. For example, in Step S113, the electrode 21 may electrolyze one of the acidic and alkaline electrolyzed water to neutralize the electrolyzed water, and then change the electrolyzed water to the other acidic and alkaline.

  Moreover, the washing | cleaning apparatus 1 may have a function which adjusts the driving | operation of the pump 5b automatically so that the quantity of the foam in the detergent water storage part 2 may become the appropriate quantity set beforehand. For example, the cleaning device 1 may include a foam sensor as an example of a foam detection unit that detects the amount of foam in the detergent water storage unit 2. This foam sensor detects the amount of the foam based on the pressure received from the foam. The control device 8 may control the pump 5b based on the detection result of the foam sensor so that the amount of foam in the detergent water storage unit 2 becomes an appropriate amount set in advance.

  In the above-described operation example, the cleaning device 1 starts and stops the operation when the operation unit 9 is operated. The time point at which the cleaning apparatus 1 starts and stops is not limited to the above-described operation example. The cleaning apparatus 1 may include, for example, a sensor that detects a user's hand. The cleaning device 1 may be configured to start and stop the operation when the user holds his / her hand toward the cleaning device 1.

  The cleaning apparatus 1 according to the present embodiment includes a detergent water storage unit 2 and a circulation unit 5c as an example of a storage unit that can store therein detergent water that is a mixture of water and detergent. The cleaning device 1 includes an electrolyzed water generating unit 20 as an example of electrolyzed water generating means for electrolyzing at least one of water stored in the detergent water storing unit 2 and the circulation unit 5c and detergent water. For this reason, the washing | cleaning apparatus 1 can wash | clean an object with the acidic foam which has the alkaline foam which has the more outstanding washing | cleaning performance, and disinfection performance.

  Moreover, the electrolyzed water production | generation part 20 which is an example of an electrolyzed water production | generation means has the electrode 21 and the ion adsorption electrode 22 arrange | positioned inside the detergent water storage part 2 and the circulation part 5c which can store detergent water inside. If it is the cleaning apparatus 1 of this Embodiment, it is not necessary to provide the apparatus which produces | generates electrolyzed water separately from the said cleaning apparatus 1. FIG. For this reason, according to this Embodiment, size reduction of the washing | cleaning apparatus 1 is implement | achieved. Furthermore, the cleaning device 1 can discharge acidic foam, alkaline foam, acidic rinse water, and alkaline rinse water to the outside from the single discharge port 6a.

  In addition, the bubble supply means which supplies the bubble for producing | generating a foam is not limited to the bubble supply part 5 shown in said embodiment. An ejector that is an example of the bubble supply means, a porous body that discharges gas into the liquid, a device that irradiates the liquid with ultrasonic waves, a device that stirs the liquid, and the like may be provided in the detergent water storage unit 2.

  The diameter of the bubbles supplied by the bubble supply means, that is, the diameter of the bubbles contained in the water flow generated by the foam generation means is preferably 0.1 μm or more and 3 mm or less, for example. When the diameter of the bubbles for generating the foam is 0.1 μm or more and 3 mm or less, the cleaning ability of the foam generated by the bubbles is more excellent.

  FIG. 6 is a diagram showing a cleaning device 1a according to a modification of the first embodiment. FIG. 6 is a diagram corresponding to FIG. The cleaning device 1a includes an electrolyzed water generating unit 20a instead of the electrolyzed water generating unit 20 of the cleaning device 1 of the above embodiment. The electrolyzed water generating unit 20 a includes an electrode 21 a instead of the electrode 21 of the electrolyzed water generating unit 20.

  The electrode 21a is formed in an L shape. At least a part of the L-shaped electrode 21 a is along the side surface of the detergent water storage unit 2 and faces the ion adsorption electrode 22. Of the surface of the electrode 21a, the surface facing the ion adsorption electrode 22 is an example of a first surface. Of the surface of the ion adsorption electrode 22, the surface facing the electrode 21a is an example of a second surface. Further, at least a part of the L-shaped electrode 21a is along the bottom surface of the detergent water reservoir 2, and the part is below the axis 2X passing through the center of the second opening 2f. The ion adsorption electrode 22 is above the axis 2X.

  Since the L-shaped electrode 21 a and the ion adsorption electrode 22 are arranged as described above, the water flow from the second opening 2 f into the detergent water storage unit 2 flows between the electrode 21 a and the ion adsorption electrode 22. Flowing. This water stream contains bubbles. In this modification, the surface of the electrode 21a facing the ion adsorption electrode 22 is cleaned by bubbles contained in the water flow. Similarly, the surface of the surface of the ion adsorption electrode 22 facing the electrode 21a is cleaned.

  According to this modification, the surface of the electrode 21a and the surface of the ion adsorption electrode 22 are prevented from being contaminated by, for example, detergent components and scales. Thereby, the fall of the efficiency in which the electrolyzed water production | generation part 20a produces | generates electrolyzed water is prevented. In addition, the same effect is acquired by arrange | positioning not only the modification shown in FIG. 6 but two electrodes which electrolyze so that the water flow containing a bubble may flow between the said electrodes. Further, the same effect can be obtained by arranging two electrodes for performing electrolysis so that a water flow containing bubbles hits at least one of the electrodes.

  For example, in the example illustrated in FIG. 1, the lower ends of the flat electrode 21 and the flat ion adsorption electrode 22 may be shifted. The length of the flat electrode 21 and the length of the flat ion adsorption electrode 22 may be different. One of the plate-like electrode 21 and the plate-like ion adsorption electrode 22 may be arranged along a portion of the wall surface of the detergent water storage portion 2 that is opposed to the second opening 2f. In addition to the configuration shown in FIG. 1, the cleaning device 1 may include a member that guides a water flow between the electrode 21 and the ion adsorption electrode 22.

Embodiment 2. FIG.
Next, a second embodiment will be described. The second embodiment will be described focusing on the differences from the first embodiment described above. Portions that are the same as or correspond to those in the first embodiment are given the same reference numerals, and descriptions thereof are simplified and omitted.

  FIG. 7 is a diagram schematically illustrating the configuration of the cleaning device 1b according to the second embodiment. FIG. 8 is a view showing a cross section taken along the line AA of FIG. In addition, in FIG. 7, illustration of the bubble supply part 5 is abbreviate | omitted.

  The basic configuration of the cleaning apparatus 1b of the present embodiment is the same as that of the cleaning apparatus 1 of the first embodiment. Cleaning device 1b includes electrolyzed water generating unit 20b instead of electrolyzed water generating unit 20 in the first embodiment. The electrolyzed water generation unit 20b includes an electrode 21b, an ion adsorption electrode 22b, and a power source 23b. The electrode 21b is the same member as the electrode 21 of the first embodiment. The ion adsorption electrode 22b is a member similar to the ion adsorption electrode 22 of the first embodiment. The power source 23b is the same member as the power source 23 of the first embodiment. The operation of the cleaning device 1b is illustrated by the flowchart of FIG. 5 as an example, as in the first embodiment.

  As shown in FIG. 8, the electrode 21b and the ion adsorption electrode 22b of the present embodiment face each other across an axis 2X passing through the center of the second opening 2f. By arranging the electrode 21b and the ion adsorption electrode 22b in this manner, the water flow from the second opening 2f into the detergent water storage unit 2 flows between the electrode 21b and the ion adsorption electrode 22b. If it is the washing | cleaning apparatus 1b of this Embodiment, the fall of the efficiency in which the electrolyzed water production | generation part 20b produces | generates electrolyzed water is prevented similarly to the modification of Embodiment 1 mentioned above.

  Of the surface of the electrode 21b, the surface facing the ion adsorption electrode 22b is an example of a first surface. Of the surface of the ion adsorption electrode 22b, the surface facing the electrode 21b is an example of a second surface. Of the surface of the electrode 21b, the surface facing the ion adsorption electrode 22b may be along the axis 2X. By arranging the electrode 21b in this way, the water flow from the second opening 2f into the detergent water storage section 2 flows so as to trace the surface of the electrode 21b facing the ion adsorption electrode 22b. This water flow separates the gas generated on the surface of the electrode 21b by electrolysis from the surface. Thereby, the fall of the efficiency in which the electrolyzed water production | generation part 20b produces | generates electrolyzed water is further prevented.

  Similarly, the surface of the surface of the ion adsorption electrode 22b facing the electrode 21b may be along the axis 2X. Further, the surface of the electrode 21b facing the ion adsorption electrode 22b may be parallel to the axis 2X. The flat electrode 21b and the flat ion adsorption electrode 22b may be arranged so as to be parallel to the axis 2X.

  FIG. 9 is a diagram showing a modification of the second embodiment. As shown in FIG. 9, the electrode 21b may be disposed on the axis 2X so that the surface of the electrode 21b facing the ion adsorption electrode 22b is along the axis 2X. The electrode 21b may be disposed so as to overlap the second opening 2f on a projection plane perpendicular to the axis 2X. Also in this modification, the efficiency reduction in which the electrolyzed water generating unit 20b generates electrolyzed water is prevented.

Embodiment 3 FIG.
Next, Embodiment 3 will be described. The third embodiment will be described focusing on differences from the above-described embodiments. Portions that are the same as or equivalent to those in each of the above embodiments are given the same reference numerals, and descriptions thereof are simplified and omitted.

  FIG. 10 is a diagram schematically illustrating the configuration of the cleaning device 1c according to the third embodiment. FIG. 11 is a view showing a BB cross section of FIG. 10, illustration of the water supply part 3, the detergent supply part 4, the bubble supply part 5, the drainage part 7, the control apparatus 8, and the operation part 9 is abbreviate | omitted.

  The basic configuration of the cleaning device 1c of the present embodiment is the same as that of the cleaning device 1b of the second embodiment. In addition, the operation of the cleaning device 1c is illustrated by the flowchart of FIG. 5 as an example, as in the first and second embodiments. A detailed description of the operation of the cleaning device 1c is omitted. Hereinafter, the configuration of the cleaning apparatus 1c of the present embodiment will be described.

  Cleaning device 1c includes detergent water storage unit 30 instead of detergent water storage unit 2 in the second embodiment. Moreover, the washing | cleaning apparatus 1c is provided with the electrolyzed water production | generation part 20c instead of the electrolyzed water production | generation part 20b in Embodiment 2. FIG. The electrolyzed water generating unit 20c includes an electrode 21c and an electrode 22c. The electrode 21c is a member similar to the electrode 21b. The electrode 22c faces the electrode 21c. The electrode 22c performs electrolysis together with the electrode 21c. The electrode 21c and the electrode 22c are connected to the power source 23c. The power source 23c applies a voltage to the electrode 21c and the electrode 22c. The power source 23c may be a DC power source instead of an AC power source.

  The electrolyzed water generating unit 20 c that is an example of the electrolyzed water generating means has a diaphragm 31. The diaphragm 31 is provided between the electrode 21c and the electrode 22c. The diaphragm 31 partitions the space inside the detergent water reservoir 30 into a first space 30a and a second space 30b. The first space 30a is a space in which the electrode 21c is disposed. The second space 30b is a space in which the electrode 22c is disposed.

  The diaphragm 31 is an ion exchange membrane through which ions in the liquid can pass. The electrolyzed water generating unit 20c of the present embodiment is a two-tank type device that generates electrolyzed water by using two electrodes and an ion exchange membrane.

  The detergent water reservoir 30 is formed with a first opening 30e and a second opening 30f. The first opening 30e and the second opening 30f correspond to the first opening 2e and the second opening 2f in the first embodiment and the second embodiment, respectively. The first opening 30e and the second opening 30f of the present embodiment are openings that communicate with the first space 30a. The first opening 30e, the second opening 30f, and the second space 30b are separated by a diaphragm 31.

  In the present embodiment, the inside of the circulation part 5c communicates with the first space 30a through the second opening 30f. The inside of the circulation part 5 c and the second space 30 b are separated by a diaphragm 31. That is, the circulation part 5c communicates only with the first space 30a out of the first space 30a and the second space 30b.

  The circulation part 5c only needs to communicate with only one of the first space 30a and the second space 30b. For example, the circulation unit 5c may communicate only with the second space 30b among the first space 30a and the second space 30b.

  Similarly to the second embodiment, the electrode 21c and the electrode 22c are opposed to each other with an axis 30X passing through the center of the second opening 30f interposed therebetween. As an example, the axis 30 </ b> X passes between the electrode 21 c and the diaphragm 31.

  In the present embodiment, the detergent is supplied to the first space 30a through which the circulation unit 5c communicates. No detergent is supplied to the second space 30b. That is, detergent water is stored in the first space 30a, and water is stored in the second space 30b.

  Electrolysis of the electrode 21c and the electrode 22c generates electrolyzed water in the first space 30a and the second space 30b. Electrolyzed water containing detergent components is generated in the first space 30a. Electrolyzed water that does not contain detergent components is generated in the second space 30b. The electrolyzed water generated in the second space 30b can be used as rinse water. Moreover, foam | bubble is produced | generated from the electrolyzed water containing the component of a detergent in the 1st space 30a because the pump 5b drive | operates. The two-tank electrolyzed water generator 20c can simultaneously generate foam and rinse water.

  For example, the cleaning device 1c of the present embodiment can simultaneously generate alkaline foam and acidic rinse water. Moreover, the washing | cleaning apparatus 1c can produce | generate an acidic foam and alkaline rinse water simultaneously. With the cleaning device 1c according to the present embodiment, it is possible to eliminate the time lag from when the foam is discharged until the rinse water is discharged. The cleaning device 1c of the present embodiment is more convenient for the user. In addition, the electrolyzed water production | generation part 20c may be not only the above-mentioned 2 tank type but a 3 tank type which has an intermediate chamber, for example.

  Further, according to the present embodiment, the configuration in which the circulation part 5c communicates with only one of the first space 30a and the second space 30b allows the foam and the rinse water to be simultaneously applied without adding a wasteful device. A cleaning device 1c that can be produced is obtained.

  A gate valve 32 may be provided inside the detergent water storage unit 30. The gate valve 32 selectively allows the first space 30 a or the second space 30 b to communicate with the inside of the discharge unit 6. The gate valve 32 prevents foam remaining in the first space 30a and the discharge unit 6 from flowing into the second space 30b. The gate valve 32 is supported by the fulcrum 33, for example. The gate valve 32 rotates around this fulcrum 33 as an axis. As an example, the gate valve 32 is opened and closed by increasing the pressure of the foam. By using the pressure increase of the foam, it is not necessary to separately provide a device for operating the gate valve 32.

  The structure of the gate valve 32 is not limited to the above-described one, and for example, the gate valve 32 may be automatically opened and closed according to the operation of the operation unit 9 by the user. The gate valve 32 may be electrically controlled by the control device 8. In addition, the cleaning device 1c may include a member that communicates with the first space 30a and a member that communicates with the second space 30b, instead of the discharge unit 6. In the cleaning device 1c, an opening for discharging foam and an opening for discharging rinsing water may be formed separately.

Embodiment 4 FIG.
Next, a fourth embodiment will be described. The fourth embodiment will be described with a focus on differences from the above-described embodiments. Portions that are the same as or equivalent to those in each of the above embodiments are given the same reference numerals, and descriptions thereof are simplified and omitted.

  FIG. 14 is a diagram schematically illustrating the configuration of the cleaning device 1f according to the fourth embodiment. The basic configuration of the cleaning device 1f is the same as that of the cleaning device 1c of the third embodiment. In addition, in FIG. 14, illustration of the water supply part 3, the detergent supply part 4, the drainage part 7, the control apparatus 8, the operation part 9, and the power supply 23c is abbreviate | omitted.

  The cleaning device 1f of the present embodiment includes a bubble supply unit 52 instead of the bubble supply unit 5 in the cleaning device 1c of the third embodiment. The bubble supply unit 52 includes two bubble generators 52a as members corresponding to the bubble generator 5a. The bubble supply unit 52 includes an air pump 52b and a joint 52c for supplying air.

  The bubble generator 52a is a member formed of a porous material. The bubble generator 52a generates bubbles by supplying air from the air pump 52b to the bubble generator 52a. The bubble generator 52a is disposed in each of the first space 30a and the second space 30b. The bubble generator 52a is connected to the air pump 52b through a joint 52c.

  The joint 52c is a member having a structure branched into three. The joint 52c includes a mechanism for opening and closing the inside of the joint 52c.

By driving the air pump 52b in this state, foam is generated in one of the first space 30a and the second space 30b.

  The cleaning device 1 f configured as described above can eliminate the time lag from when the foam is discharged until the rinse water is discharged, as with the cleaning device 1 c of the third embodiment. In addition, the cleaning device 1f can continuously discharge two types of foam, as in the modification of the third embodiment. In the present embodiment, a mechanism for circulating the detergent water is unnecessary. If it is this Embodiment, the smaller washing | cleaning apparatus 1f can be obtained.

  Note that the joint 52c may be capable of allowing both of the two bubble generators 52a to communicate with the air pump 52b. Both of the two bubble generators 52a communicate with the air pump 52b, so that two types of bubbles can be generated simultaneously. Moreover, as shown in FIG. 14, the bubble generator 52a is preferably disposed below the electrode 21c and the electrode 22c, respectively. When bubbles are generated in the liquid by the bubble generator 52a formed of the porous body, the bubbles generate an upward flow in the liquid. In other words, the bubble generator 52a generates an upward flow including bubbles. By disposing the bubble generator 52a below the electrode 21c and the electrode 22c, the surface of the electrode 21c and the electrode 22c are cleaned by the upward flow containing bubbles. Thereby, the fall of the efficiency which produces | generates electrolyzed water is prevented.
