Description

  The present invention relates to a cleaning device and a kitchen sink.

  The cooking utensils used for cooking with oil and dishes that have been eaten are difficult to remove and must be scrubbed by hand with a sponge or the like. Handling the detergent with your hands may cause your hands to become rough, or the tableware to be rubbed with force. Moreover, it is a heavy labor and burden for the worker. Patent Document 1 below proposes an apparatus for cleaning dishes by discharging a cleaning liquid that is foamed by introducing air into a detergent. Thus, it is known that oil stains on tableware can be removed by floating and separating the oil adhering to the tableware with fine bubbles. Further, in Patent Document 2 below, as a dish washing method using a fine bubble generating device, fine bubbles are generated in washing water stored in a sink, and oil adhering to the tableware is removed by the fine bubbles, and floating separation is performed. There has been proposed a method of draining the oil that has overflowed.

Japanese Patent No. 5032908 JP 2008-259576 A

  In the apparatus of Patent Document 1, the amount of physical dirt removed by water pressure increases by increasing the discharge amount of the cleaning liquid, but water splashes increase and the surroundings become dirty. Moreover, since the dirt with sticking is gradually peeled off from the tableware and removed, it is difficult to remove it instantly only by discharging. Since the invention of Patent Document 2 is a system in which the oil that has been floated and separated by fine bubbles is overflowed and drained, it is necessary to fill the sink with water, and the amount of water used increases. Moreover, since the invention of patent document 2 does not use a detergent, it is difficult to remove oil stains sufficiently.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cleaning device and a kitchen sink that can remove dirt such as tableware without rubbing with a small amount of water. And

  A cleaning device according to the present invention includes a water storage unit that stores water, a circulation channel that circulates water in the water storage unit outside the water storage unit, a circulation pump that causes water to flow through the circulation channel, and a gas that flows into the circulation channel. Is provided with a gas introduction part for introducing the detergent, a detergent supply part for supplying the detergent, and a control means for controlling the operation of the circulation pump and the gas introduction part.

  According to the cleaning apparatus and kitchen sink of the present invention, it is possible to remove stains such as dishes without rubbing with a smaller amount of water than in the past.

The sink body is provided with a faucet 4 capable of injecting clean water into the water reservoir 2. A water supply pipe 5 for supplying clean water is connected to the faucet 4. A discharge port 8 serving as an outlet of the circulation channel 6 is provided on the side surface of the water storage unit 2. A suction port 9 serving as an inlet of the circulation channel 6 is provided on the bottom surface of the water reservoir 2. A drain outlet 11 is provided on the bottom surface of the water reservoir 2. The drain port 11 is connected to a sewer pipe (not shown). When water is stored in the water reservoir 2, the drain port 11 is closed with a plug (not shown). When cleaning the cleaning object 17 such as tableware and cooking utensils, the cleaning object 17 is immersed in water stored in the water storage unit 2.

  The circulation pump 7 causes water to flow through the circulation channel 6. By operating the circulation pump 7, the water in the water reservoir 2 is drawn into the circulation channel 6 from the suction port 9. The circulation channel 6 circulates water outside the water reservoir 2. The water in the circulation channel 6 is discharged from the discharge port 8 and returns to the water reservoir 2. A first electromagnetic valve 12 a that opens and closes the circulation flow path 6 is provided between the suction port 9 and the circulation pump 7.

  The gas introduction unit 10 is connected between the circulation pump 7 and the discharge port 8 of the circulation channel 6. The gas introduction unit 10 includes an intake passage 13 and a second electromagnetic valve 12 b that opens and closes the intake passage 13. The gas introduction unit 10 introduces gas (air) sucked from the intake passage 13 into the circulation channel 6, thereby generating bubbles in the water flowing through the circulation channel 6. The gas introduction part 10 in this Embodiment 1 has an ejector structure. The gas introduction part 10 has a reduced diameter part for reducing the diameter of the water flow path, and naturally sucks gas from the intake passage 13 by the negative pressure generated in the reduced diameter part. The second electromagnetic valve 12b opens and closes the intake passage 13.

  The detergent supply unit 14 is connected to a passage branched from the middle of the intake passage 13. The detergent supply unit 14 includes a third electromagnetic valve 12c that opens and closes the passage. When the gas introduction unit 10 sucks gas from the intake passage 13, the detergent together with the gas can be introduced into the circulation flow path 6 by opening the third electromagnetic valve 12c. In the first embodiment, the detergent supply unit 14 supplies the detergent via the gas introduction unit 10. Thereby, a detergent can be uniformly supplied with a simple structure. In this invention, you may comprise not only the structure of illustration but a detergent supply part supplies a detergent directly to the circulation flow path 6 or the water storage part 2. FIG.

  Although detailed illustration is omitted, the gas introduction unit 10 according to the first embodiment has fixed wings for swirling the water flow at a position upstream of the ejector structure. The gas introduction unit 10 generates fine bubbles by shearing and refining the bubbles with the swirling water flow generated by the fixed blades. The fine bubbles generated in the gas introduction unit 10 are discharged from the discharge port 8 and supplied into the water storage unit 2. By generating the fine bubbles, the contact area between the detergent and the gas is increased, the density is high, and fine bubbles can be supplied into the water storage unit 2 to improve the cleaning power. The gas introduction unit 10 is preferably capable of generating fine bubbles having an average diameter of several tens of μm or less (for example, 10 μm to 50 μm) when generated.

  The control unit 50 corresponds to a control unit that controls operations of the circulation pump 7, the gas introduction unit 10, and the detergent supply unit 14. The control unit 50 according to the first embodiment executes arithmetic processing based on a storage unit including a ROM (Read Only Memory), a RAM (Random Access Memory), and a nonvolatile memory, and a program stored in the storage unit. CPU (Central Processing Unit) that performs and an input / output port for inputting / outputting external signals to / from the CPU. The actuators and sensors included in the cleaning device 1 are electrically connected to the control unit 50.

  In addition, the gas introduction part in this invention is not limited to the structure which performs natural inhalation by an ejector structure, The structure which introduces gas using an air pump may be sufficient.

  An ultrasonic element (not shown) that generates ultrasonic waves may be provided on the side surface of the water storage unit 2. By providing an ultrasonic element on the side surface of the water storage unit 2, dirt attached to the water storage unit 2 can be removed, which is effective for cleaning the water storage unit 2 after cleaning the cleaning object 17 such as tableware and cooking utensils. is there.

  The control unit 50 may control the detergent supply amount by the detergent supply unit 14 according to one or both of the water storage amount of the water storage unit 2 and the amount of the cleaning object 17. As a means for detecting the amount of water stored in the water storage section 2, for example, it can be calculated by detecting the water level of the water storage section 2 with the pressure sensor 20 provided in the circulation flow path 6. As a means for detecting the amount of the cleaning object 17, for example, the strain sensor 21 detects the strain at the bottom of the water storage unit 2, and detects the load acting on the bottom of the water storage unit 2. The amount can be detected. The detergent supply amount can be controlled by the valve opening time of the third electromagnetic valve 12c. The control unit 50 increases the detergent supply amount as the water storage amount of the water storage unit 2 increases. The controller 50 increases the detergent supply amount as the amount of the cleaning object 17 increases. The control unit 50 controls the detergent supply amount, so that the detergent usage can be easily optimized. In the first embodiment, the control unit 50 controls the operation of the detergent supply unit 14, but in the present invention, the detergent supply unit may be manually operated.

  FIG. 2 is a flowchart showing the operation of the cleaning apparatus 1 according to the first embodiment. FIG. 3 is a diagram illustrating a state in the cleaning process of the cleaning device 1 according to the first embodiment. Hereinafter, the operation of the cleaning apparatus 1 of the first embodiment will be described with reference to FIGS. When cleaning is performed, first, the object to be cleaned 17 is placed in the water storage unit 2 with the drain port 11 closed, and water is supplied from the faucet 4 to accumulate water in the water storage unit 2 (step S1). Next, the controller 50 starts the following cleaning process. First, the control unit 50 opens the first electromagnetic valve 12a of the circulation channel 6, operates the circulation pump 7, and opens the second electromagnetic valve 12b of the gas introduction unit 10 (step S2). As a result, fine bubbles are supplied into the water reservoir 2. Subsequently, the control unit 50 supplies the detergent by opening the third electromagnetic valve 12c of the detergent supply unit 14 (step S3). Subsequently, the control unit 50 performs a circulation operation for continuing the operation of the circulation pump 7 for a predetermined time (step S4).

  As shown in FIG. 3, a large amount of foam 19 containing a detergent is generated in the water storage unit 2 by the operation of the cleaning process from Step S <b> 2 to Step S <b> 4 described above. When a part of the cleaning object 17 protrudes above the water surface 3, the portion of the cleaning object 17 that protrudes above the water surface 3 is gradually covered with the bubbles 19. In the process in which the bubbles 19 increase, the bubbles 19 move on the surface of the portion 17 to be cleaned that protrudes above the water surface 3, so that a physical action works, and the dirt on the surface can be efficiently cleaned. With respect to the portion 17 to be cleaned in the water, dirt can be efficiently cleaned by the effect of the water flow discharged from the discharge port 8 and the effect of fine bubbles. The dirt 18 separated from the cleaning object 17 floats near the water surface 3. According to the cleaning apparatus 1, since the dirt of the cleaning object 17 can be efficiently removed as described above, scrubbing becomes unnecessary, and the labor of the operator can be reduced. In particular, since the dirt of the cleaning object 17 in the portion above the water surface 3 can be efficiently cleaned, only a small amount of water can be stored in the water storage unit 2, and the amount of water used can be reduced.

  The control part 50 complete | finishes a washing | cleaning process by stopping the circulation pump 7 after predetermined time passes by circulation driving | operation (step S5). When the washing process is completed, the drain port 11 is opened, and the water in the water storage unit 2 is discharged together with the bubbles 19 (step S6). At this time, as the water level of the water storage section 2 decreases, the bulk of the bubbles 19 decreases. When the volume of the bubble 19 decreases, the surface of the object to be cleaned 17 moves physically on the surface of the object 17 to be cleaned. For this reason, it is possible to prevent the dirt 18 from reattaching to the cleaning object 17. You may perform the drainage process of step S6 by opening the drain outlet 11 manually. Further, an actuator (not shown) for opening and closing the drain port 11 may be provided, and the control unit 50 may automatically control the drainage process. Even when the cleaning object 17 is pulled up from the water storage unit 2 without draining, the bubbles 19 are physically cleaned by moving on the surface of the cleaning object 17.

  When the draining process is completed, the faucet 4 is opened, and the cleaning object 17 is rinsed with clean water from the faucet 4 (step S7). The rinsing process in step S7 may be performed by manually opening the faucet 4. Further, an actuator (not shown) for opening and closing the faucet 4 may be provided, and the control unit 50 may automatically control the rinsing process. In that case, in the rinsing step, the drainage port 11 is closed and the water from the faucet 4 is stored in the water storage section 2, the circulation pump 7 is operated, and the water flow discharged from the discharge port 8 is applied to the object to be cleaned 17. good.

  In the first embodiment, by providing the suction port 9 of the circulation channel 6 at a position lower than the discharge port 8, water can be circulated through the circulation channel 6 even if the water level of the water storage unit 2 is low. For this reason, even if there is little quantity of the water stored in the water storage part 2, the washing | cleaning target 17 can be wash | cleaned. In particular, in the first embodiment, by providing the suction port 9 on the bottom surface of the water storage unit 2, even if the amount of water stored in the water storage unit 2 is particularly small, water can be circulated through the circulation channel 6 and the object to be cleaned The object 17 can be washed.

  As shown in FIG. 1, in the first embodiment, the suction port 9 of the circulation flow path 6 is on one side with respect to the virtual vertical surface 22 that bisects the water storage section 2. 8 is on the other side of the virtual vertical plane 22. With such a configuration, when the circulation pump 7 is operated, it is possible to reliably suppress the generation of a region where water is stagnated in the water storage unit 2, and the cleaning effect can be improved. The virtual vertical surface 22 may be perpendicular to the longitudinal direction of the water reservoir 2 or may be parallel to the longitudinal direction of the water reservoir 2.

  In the first embodiment, the discharge port 8 of the circulation flow path 6 is provided at one location, but the downstream side of the circulation flow channel 6 may be branched into a plurality of locations, and the discharge ports 8 may be provided at a plurality of locations. With this configuration, it is possible to supply fine bubbles from multiple directions to the water storage unit 2, and uniform cleaning performance can be obtained regardless of how the cleaning object 17 is placed.

  In the circulation operation of step S4, the foaming of the detergent proceeds and the volume of the foam 19 continues to increase, so that the foam 19 may overflow from the water storage unit 2. The cleaning device 1 according to the first embodiment can improve the usability by including an overflow suppression unit that suppresses the foam 19 from overflowing from the water storage unit 2.

  As shown in FIG. 3, a sensor 15 is provided on the side surface of the water storage unit 2 as detection means for detecting the bubbles 19 or water just before the bubbles 19 overflow from the water storage unit 2. The sensor 15 is preferably arranged at a position near the full water in the water storage unit 2. As the sensor 15, for example, a piezoelectric sensor that detects bubbles or water due to a decrease in potential when a wet object adheres to the sensor unit, or a pyroelectric sensor that detects an obstacle at the sensor position, or the like is used. be able to.

  When the sensor 15 detects the bubble 19 or water in the circulation operation of step S4, the control unit 50 closes the second electromagnetic valve 12b of the gas introduction unit 10. Thereby, since supply of the fine bubble from the gas introduction part 10 to the water storage part 2 stops, the production | generation of the bubble 19 of the water storage part 2 stops. Thereby, it can suppress that the bubble 19 overflows from the water storage part 2. FIG. In addition, when the sensor 15 detects the bubble 19 or water, the control unit 50 temporarily interrupts the operation of the circulation pump 7 instead of closing the second electromagnetic valve 12b of the gas introduction unit 10. Also good. Even in this case, the supply of the fine bubbles to the water storage unit 2 is stopped and the generation of the bubbles 19 in the water storage unit 2 is stopped, so that the bubbles 19 can be prevented from overflowing from the water storage unit 2. Thus, when the sensor 15 detects the bubble 19 or water, by controlling one or both of the circulation pump 7 and the gas introduction unit 10 so that the generation of the bubble 19 of the water storage unit 2 is suppressed. An overflow suppression means can be configured.

  Further, the overflow suppression means may include a defoaming means for eliminating the bubbles 19 in the water storage unit 2. The cleaning device 1 according to the first embodiment includes a defoaming device 23 as a defoaming unit. The defoaming device 23 jets an air flow and blows the air flow (wind) on the upper portion of the bubble 19 to erase the upper portion of the bubble 19. When the sensor 15 detects the bubble 19 or water, the control unit 50 can configure the overflow suppression means by erasing the upper portion of the bubble 19 with the defoaming device 23. The method in which the defoaming device 23 erases the bubbles 19 is not limited to the method of blowing the airflow, but may be a method of applying water or a method of applying vibration.

  Further, in the circulation operation of step S4, the control unit 50 intermittently opens and closes the second electromagnetic valve 12b of the gas introduction unit 10, and controls the gas introduction unit 10 to intermittently introduce gas. You may suppress that the bubble 19 overflows from the water storage part 2. FIG. When the second electromagnetic valve 12b is open, the fine bubbles are supplied from the gas introduction unit 10 to the water storage unit 2, so that the volume of the bubbles 19 in the water storage unit 2 increases. When the second electromagnetic valve 12b is closed, the supply of fine bubbles from the gas introduction unit 10 to the water storage unit 2 is stopped, so that the volume of the bubbles 19 in the water storage unit 2 decreases with time. By intermittently opening and closing the second electromagnetic valve 12b, the volume of the foam 19 in the water storage section 2 repeatedly increases and decreases, so that it is possible to suppress the foam 19 from overflowing from the water storage section 2. The overflow control means can be configured by the above control. In this case, the control unit 50 controls the water storage unit 2 based on at least one of the water storage amount of the water storage unit 2, the detergent supply amount by the detergent supply unit 14, and the gas introduction amount from the gas introduction unit 10. One or both of the circulation pump 7 and the gas introduction unit 10 may be controlled so as to more reliably suppress the overflow of the bubbles 19. The detergent supply amount can be detected by the valve opening time of the third electromagnetic valve 12c. The amount of gas introduced from the gas introduction part 10 can be detected by the valve opening time of the second electromagnetic valve 12b. The control unit 50 increases the at least one of the above-described water storage amount, detergent supply amount, and gas introduction amount so that the closing period when the second electromagnetic valve 12b is opened / closed intermittently becomes longer. It can suppress more reliably that the bubble 19 overflows from 2. Or the control part 50 drives the circulation pump 7 intermittently in the circulation operation of step S4, and the circulation pump 7 is increased as at least one of the above-described water storage amount, detergent supply amount, and gas introduction amount increases. By lengthening the stop period when driving intermittently, the overflow of the bubbles 19 from the water reservoir 2 can be more reliably suppressed.

  FIG. 4 is a graph showing the oil removal rate when a dish on which oil has been dropped is washed for 10 minutes under various conditions. In FIG. 4, “water immersion” represents normal immersion in water, “microbubble immersion” represents immersion in water containing fine bubbles, and “fine bubbles + detergent immersion” represents water containing fine bubbles and detergent. "Detergent foam soaking" represents soaking in foam containing detergent, and "rinse for 10 seconds after soaking detergent" is a 10 second rinse step after soaking in foam containing detergent Represents the case where is added. As shown in FIG. 4, the oil removal rate is higher in the fine bubble immersion than in the water immersion. The oil removal rate is further improved by using a detergent in combination with the fine bubbles. Moreover, detergent foam immersion not immersed in water also shows a higher oil removal rate than normal water immersion. By adding a rinsing process for 10 seconds after the detergent foam immersion, the oil removal rate can be improved in the same manner as the conditions in which fine bubbles and detergent are used in combination.

  According to the cleaning device 1 of the first embodiment, the bubbles 19 containing the detergent can be generated on the water surface 3 by supplying the fine bubbles and the detergent to the water reservoir 2. Therefore, the adhering dirt can also be reliably peeled and removed by the cleaning power of the bubbles 19 in the portion 17 to be cleaned above the water surface 3.
