When the foam diameter of the foam is small, a high cleaning effect can be obtained for the object to be cleaned. However, the smaller the foam diameter, the more difficult it is for the foam to disappear, so there is a problem that the time required for rinsing and the amount of water increase. There is a method of irradiating ultrasonic waves as a means of extinguishing bubbles, but since a device for generating ultrasonic waves is required, there are disadvantages that the size of the device becomes large and the cost increases. Further, it is conceivable to use a defoaming agent as a means for defoaming foam, but especially when washing dishes, it is necessary to thoroughly wash away the defoaming agent itself, so as a defoaming means. Not suitable.

Hereinafter, embodiments will be described with reference to the drawings. Common or corresponding elements in the drawings are designated by the same reference numerals to simplify or omit duplicate description. The present disclosure may include any combination of configurable configurations among the configurations described in each of the following embodiments.

Embodiment 1.
FIG. 1 is a configuration diagram showing a cleaning device 1 according to the first embodiment. The cleaning device 1 of the first embodiment can generate foam for cleaning an object. In the present specification, the foam refers to a creamy foam (foam) formed by collecting a large number of bubbles. Foam is produced from water and detergent or surfactant. In the following description, the water mixed with the detergent is referred to as "washing water", and the object to be washed by the washing device 1 is referred to as "object to be washed". The object to be washed may be, for example, tableware, cooking utensils, and the like.

As shown in FIG. 1, the cleaning device 1 of the present embodiment includes a foam storage unit 2, a bubble generation unit 6, a rinse water generation unit 9, and the like. The foam storage unit 2 has an internal space capable of storing wash water and foam. Foam is generated on the water surface 95 of the washing water stored in the internal space of the foam storage unit 2, that is, on the gas-liquid interface. The foam storage unit 2 in the present embodiment is a tubular container having a vertical direction as a longitudinal direction. FIG. 1 represents the foam storage portion 2 as a schematic cross-sectional view. The cleaning device 1 may further include a control device 50 that controls the operation of valves, pumps, and the like, which will be described later.

The bubble generation unit 6 generates bubbles in the foam storage unit 2. The bubble generating unit 6 includes a circulation pump 7, a bubble generator 8, and a circulation flow path 29. The circulation pump 7 and the bubble generator 8 are arranged in the middle of the circulation flow path 29. The circulation flow path 29 is connected to the foam storage unit 2. When the circulation pump 7 is operated, the washing water is drawn into the circulation flow path 29 from the foam storage portion 2. The washing water flows along the circulation flow path 29, passes through the circulation pump 7 and the bubble generator 8, and flows into the foam storage unit 2 again.

The bubble generator 8 generates bubbles by introducing a gas into the washing water flowing through the circulation flow path 29. The bubble generator 8 is arranged on the downstream side of the circulation pump 7 in the circulation flow path 29. An intake passage 30 is connected to the bubble generator 8. The bubble generator 8 generates bubbles by mixing the gas (for example, air) sucked from the intake passage 30 with the washing water flowing through the circulation flow path 29.

The bubble generator 8 may be, for example, an ejector having the following structure. The ejector has a reduced diameter portion that reduces the diameter of the water flow path. Due to the negative pressure generated in this reduced diameter portion, gas can be naturally aspirated from the intake passage 30. In the reduced diameter portion, gas is introduced through the intake passage 30 from a direction perpendicular to the flow of the washing water. It is preferable that the position on the upstream side of the ejector is provided with a fixed blade that swivels the liquid flow, that is, the water flow, that flows into the ejector. The fixed blade forms, for example, a swirling flow centered on the axis of the flow path. The swirling flow of the washing water formed by the fixed blades shears the bubbles to make them finer, so that the bubble diameter of the bubbles supplied into the foam storage portion 2 can be made smaller.

The method of inhaling from the intake passage 30 is not limited to naturally aspirated. Air may be forcibly supplied to the bubble generator 8 by using an air pump (not shown).

The bubble generating portion in the present invention is not limited to the one having the ejector as described above. For example, the bubble generating portion may generate bubbles by releasing a gas into the washing water from a large number of fine pores provided in the porous body (not shown). In that case, the porous body may be arranged inside the foam storage portion 2. Air can be sent from an air pump (not shown) to the porous body, and air can be discharged into the washing water through a large number of fine pores in the porous body. The material of the porous body may be, for example, a metal mesh, ceramics, a resin material, or the like. Alternatively, the bubble generating portion may be provided with an ultrasonic irradiation means for irradiating the washing water with ultrasonic waves. For example, by irradiating the washing water with ultrasonic waves in the frequency range of 20 kHz to several MHz from the ultrasonic irradiation means, it is possible to generate bubbles, particularly fine bubbles.

The cleaning device 1 of the present embodiment includes a detergent storage unit 5 for storing detergent. The detergent storage unit 5 is connected to a circulation flow path 29 on the downstream side of the bubble generator 8. By opening the valve 19 provided between the detergent storage unit 5 and the circulation flow path 29, detergent can be injected from the detergent storage unit 5 into the circulation flow path 29. The valve 19 may also have a function of a check valve for preventing the water flow flowing through the circulation flow path 29 from flowing back to the detergent storage unit 5. Instead of the configuration shown in the figure, a configuration in which the detergent can be directly injected into the foam storage unit 2 from the detergent storage unit 5 may be used.

By generating bubbles in the foam storage unit 2 by the bubble generation unit 6, bubbles are generated on the water surface 95 of the washing water inside the foam storage unit 2. The operation of generating bubbles in this way is hereinafter referred to as "foam generation operation". The foam generation operation is as follows. The air bubbles supplied into the washing water inside the foam storage unit 2 float toward the water surface 95 of the washing water due to buoyancy. When the bubbles float on the surface 95 of the washing water, a large number of bubbles are collected in a state where the outer circumference of the bubbles is covered with a detergent, that is, a surfactant, so that bubbles are generated. As the foam begins to form, the foam rises above the surface 95 of the wash water. As the foam generation operation is continued, the foam on the water surface 95 continues to grow. Eventually, the space above the water surface 95 in the foam storage portion 2 is filled with bubbles.

A conduit 12 is connected to the upper part of the foam storage portion 2. A nozzle portion 13 for discharging foam is provided at the tip end portion of the conduit 12. The conduit 12 has a passage for sending the foam inside the foam storage portion 2 to the nozzle portion 13. Even after the space above the water surface 95 in the foam storage unit 2 is filled with foam, the foam generation operation is continued, so that the foam reaches the nozzle unit 13 from the inside of the foam storage unit 2 through the conduit 12 and the nozzle. Foam is discharged from the portion 13.

According to this embodiment, the following effects can be obtained. Since the foam discharged from the nozzle unit 13 can be attached to the object to be cleaned outside the foam storage unit 2, the amount of foam used during cleaning can be suppressed. By suppressing the amount of foam used, the treatment of the rinsing step after washing, that is, the defoaming treatment for eliminating the foam becomes easy. Since the foam storage unit 2 does not contain the object to be cleaned, the volume can be reduced. Since the volume of the foam storage unit 2 is small, the consumption of washing water can be suppressed. Since the volume of the foam storage unit 2 is small, the time from the start of the foam generation operation in the foam storage unit 2 to the ejection of the foam by the nozzle unit 13 can be shortened.

The nozzle portion 13 may be movable with respect to the foam storage portion 2. For example, the nozzle portion 13 and the conduit 12 may be rotatable with respect to the foam storage portion 2. The conduit 12 may be made of a hard material. Alternatively, the conduit 12 may be composed of a bendable member, such as a hose or bellows tube. The conduit 12 may have a structure that can be expanded and contracted in length. By making the conduit 12 bendable or expanding and contracting the length of the conduit 12, the nozzle portion 13 can be moved closer to the object to be cleaned, so that the usability is improved.

By arranging the object to be cleaned under the nozzle portion 13, the foam discharged from the nozzle portion 13 can be supplied to the upper part of the object to be cleaned. The cleaning component contained in the foam can remove dirt adhering to the object to be cleaned. The foam adhering to the upper part of the object to be cleaned moves to the lower part of the object to be cleaned by gravity. As the bubbles move on the surface of the object to be cleaned, shear stress, that is, shear stress acts on the dirt on the surface of the object to be cleaned, so that the dirt can be removed more efficiently even with a small amount of foam. Become.

The volume average diameter of the bubbles generated by the bubble generating unit 6 may be in the range of, for example, 60 μm to 1000 μm. The bubble diameter can be measured by, for example, a laser diffraction / scattering method, a particle tracking analysis method, a dynamic light scattering method, a resonance type mass measurement method, or the like. The bubbles generated from the bubble generating unit 6 preferably include bubbles having a diameter in the range of 1 μm to 50 μm. When air bubbles having a diameter in the range of 1 μm to 50 μm are included, the finer texture of the generated foam improves the contact area with the object to be cleaned, and a higher cleaning effect can be obtained.

The rinse water generation unit 9 generates rinse water containing ions. The water supply unit 4 includes a flow path for supplying water to the foam storage unit 2 and the rinse water generation unit 9. The water supply unit 4 guides water supplied from a water source such as a tap water to the foam storage unit 2 and the rinse water generation unit 9. When the valve 16 is opened, water is supplied from the water supply unit 4 to the foam storage unit 2. When the valve 16 is closed, the water supply from the water supply unit 4 to the foam storage unit 2 is stopped. When the valve 15 is opened, water is supplied from the water supply unit 4 to the rinse water generation unit 9. When the valve 15 is closed, the water supply from the water supply unit 4 to the rinse water generation unit 9 is stopped.

After cleaning the object to be cleaned with the foam discharged from the nozzle unit 13, rinsing is performed using the rinse water generated by the rinse water generation unit 9. The rinse water generated by the rinse water generation unit 9 contains cations. By the action of this cation, the surface tension of the foam can be lowered, the thinning of the foam film can be promoted, and the foam can be quickly extinguished. Therefore, the time required for defoaming and the amount of water can be reduced.

The cleaning device 1 includes an ion supply unit 27 that supplies ions to the rinse water. The ion supply unit 27 is installed inside the rinse water generation unit 9. The ion supply unit 27 may supply cations (metal ions). The ion supply unit 27 may be provided with, for example, a pair of electrodes, and a voltage may be applied between the electrodes to elute metal ions from the electrodes. Alternatively, the ion supply unit 27 may include an ion-containing material. The ion-containing material may be, for example, at least one of an ion exchange resin, an ion kneaded resin, and a water-soluble glass carrying ions. For example, the ion supply unit 27 may supply ions by performing ion exchange with an ion exchange resin. Alternatively, the ion supply unit 27 may supply the ions by eluting the ions from the ion-kneaded resin or the water-soluble glass carrying the ions. The ion supply unit 27 may supply at least one of calcium ion, magnesium ion, and vanadium ion, for example.

The ions supplied from the ion supply unit 27 may contain at least one of copper ions, silver ions, iron ions, zinc ions, and platinum ions. By using rinse water containing at least one metal ion of copper ion, silver ion, iron ion, zinc ion, and platinum ion, in addition to the effect of promoting defoaming of bubbles, the object to be washed after rinsing is completed. The surface of an object can be antibacterialized by the metal ions.

A flow path switching valve 18 is installed between the foam storage unit 2 and the conduit 12. The flow path switching valve 18 may be, for example, a three-way valve. The rinse water passage 11 connects the rinse water generation unit 9 and the flow path switching valve 18. The flow path switching valve 18 has a first flow path form in which the upper part of the foam storage portion 2 communicates with the conduit 12 to block the rinse water passage 11, and the flow path switching valve 18 communicates the upper part of the foam storage portion 2 with the conduit 12 to block the rinse water passage 11. It is possible to switch to the second flow path form that shuts off. When the foam is discharged from the nozzle portion 13, the flow path switching valve 18 is in the first flow path form. By switching the flow path switching valve 18 to the second flow path form, the rinse water generated by the rinse water generation unit 9 is passed through the rinse water passage 11, the flow path switching valve 18, and the conduit 12 to the nozzle unit 13. Can be discharged from. The flow path switching valve 18 switches between a flow path form in which bubbles are supplied from the foam storage section 2 to the nozzle section 13 and a flow path form in which rinse water is supplied from the rinse water generation section 9 to the nozzle section 13. This is an example of switching means.

The nozzle portion 13 in the present embodiment is an example of a discharge portion that discharges foam and rinse water. In the present embodiment, the following effects can be obtained by being able to discharge foam and rinse water from the common nozzle portion 13. The size of the device can be reduced as compared with a configuration in which a discharge unit for discharging foam and a discharge unit for discharging rinse water are separately provided.

A drainage unit 3 is connected to the bottom of the foam storage unit 2. When the valve 17 is opened, the washing water in the foam storage unit 2 is discharged to the outside through the drainage unit 3. A drainage unit 10 is connected to the bottom of the rinse water generation unit 9. When the valve 14 is opened, the water in the rinse water generation unit 9 is discharged to the outside through the drainage unit 10. The drainage portions 3 and 10 may be connected to a drainage pipe.

In the present embodiment, cleaning can be performed by adhering creamy foam to the object to be cleaned instead of washing water containing air bubbles. Therefore, since the amount of washing water used is small, the consumption of water and detergent can be suppressed. Further, even when cleaning a delicate object to be cleaned such as a glass product or a plated product, it is possible to surely suppress damage to the object to be cleaned.

FIG. 2 is a flowchart showing a cleaning operation using the cleaning device 1 of the first embodiment. For example, when the user presses the cleaning start button (not shown) provided in the cleaning device 1, the operation of the cleaning device 1 is started. At this point, the inside of the foam storage unit 2 is empty. First, the control device 50 keeps the valve 17 of the drainage unit 3 closed, and opens the valve 16 of the water supply unit 4 to supply water into the foam storage unit 2 (step S1 in FIG. 2). As a result, water accumulates inside the foam storage unit 2, and the water level in the foam storage unit 2 rises. When water is collected to a water level higher than the position of the bubble generation unit 6, that is, the connection position between the circulation flow path 29 and the foam storage unit 2, the control device 50 closes the valve 16 of the water supply unit 4 to store the foam storage unit. Stop the water supply to the inside of 2.

Next, the control device 50 supplies the detergent from the detergent storage unit 5 into the circulation flow path 29 of the bubble generation unit 6 by opening the valve 19 of the detergent storage unit 5 (step S2). Next, the control device 50 starts the operation of the circulation pump 7 of the bubble generating unit 6 (step S3). As a result, the washing water in the foam storage unit 2 circulates in the circulation flow path 29 of the bubble generation unit 6 (step S4). When the wash water circulates in the circulation flow path 29, bubbles are generated in the bubble generator 8 and the bubbles flow into the foam storage unit 2. Bubbles float on the water surface 95 in the foam storage unit 2, so that bubbles are generated on the water surface 95 (step S5). By continuing the foam generation operation, the water surface 95 in the foam storage portion 2 is filled with foam, and the foam flows out to the conduit 12 (step S6). The foam passes through the conduit 12 and is discharged from the nozzle portion 13 (step S7). The foam discharged from the nozzle portion 13 covers the object to be cleaned, so that the object to be cleaned is cleaned (step S8).

When the cleaning of the object to be cleaned with foam is completed, the control device 50 switches the flow path switching valve 18 from the first flow path form to the second flow path form, and opens the valve 15 of the water supply unit 4 to generate the rinse water. Water is supplied into 9 (step S9). Rinse water containing ions is generated in the rinse water generation unit 9. The rinse water passes through the rinse water passage 11, the flow path switching valve 18, and the conduit 12 (step S10), and is discharged from the nozzle portion 13 (step S11). The rinse water discharged from the nozzle portion 13 washes away the bubbles covering the object to be cleaned and extinguishes the bubbles (step S12).

In the present embodiment, the operation unit 28 is installed in the conduit 12. The operation unit 28 may be configured to operate the opening and closing of a valve (not shown) in the middle of the conduit 12. In that case, the user can easily suspend or resume the discharge of foam or rinse water from the nozzle unit 13 by operating the operation unit 28.

In general, foam having a small foam diameter has a problem that it is difficult to extinguish the foam while exerting a high cleaning effect on the object to be cleaned. With the cleaning device 1 of the present embodiment, even bubbles having a small bubble diameter can be quickly defoamed by the action of cations contained in the rinse water generated by the rinse water generation unit 9. .. Therefore, it is possible to achieve both the use of foam having a small foam diameter and a high cleaning effect and the reduction of the time required for defoaming the foam and the amount of water.
