Description

Automatic washing device and its operation control method {A auto handwasher and control method of the same}

The present invention relates to a washing device for washing hands and a method for controlling the operation thereof, and in particular, water and soap are sprayed at the same time, and the process of drying the washed hands can be performed automatically in one cycle, such as soap, towels, etc. There is no need to separately provide such an article, and not only can be installed on the sink, but also relates to an automatic washing device and its operation control method that can be used as a mobile sink.

In general, toilets for public hand washes, various restaurants, and entertainment venues are equipped with hand washing facilities for hand washing. Such toilet facilities are provided with water supplies, soaps and towels so that the user can hygienically wash their hands.

Since the toilet is a place used by many people, it is necessary to clean the area around which soap is placed frequently, and the towels should be replaced frequently so that the toilet can be kept clean without getting dirty. Therefore, in the restaurant or entertainment venues, the toiletries place a lot of care to always maintain the cleanliness, there is also a situation where there is a separate management personnel.

In addition, since public toilets are used by more people than the above restaurants and entertainment venues, soap is easily consumed and towels are also easily soiled. Therefore, although a separate hygiene manager is employed and managed from time to time, cleanliness in public places, which should be kept clean at all times, is deteriorated because the hygiene manager alone is insufficient to cleanly clean toilet facilities in public places. Where there is no reach, the problem of having to rely on public awareness of the public is a problem.

On the other hand, when washing hands or face in the sink, there is a problem that the water resources are unnecessary waste because the soap is in the state that the tap water is discharged as it is.

As a solution for overcoming the above problems, the present applicant has proposed an automatic washing device of Patent No. 0305500 and an operation control method thereof, which will be briefly described with reference to FIG. 1 as follows.

As shown in the figure, the main frame 101 is provided with an interlayer partition plate at predetermined intervals; A sensor 102 installed at a predetermined upper position of the main frame 101 to sense that a hand is inserted into a hand washing space; A water supply unit 103 installed on the lower compartment of the main frame 101 and supplied with water for hand washing; A water soap supply unit 104 installed on an intermediate section of the main frame 101 to supply water soap required for hand washing; A hand washing and drying unit 105 installed at the upper predetermined position of the main frame 101 for the hand washing and drying; The control unit 106 receives the detection signal of the sensor 102 and controls the overall driving operation of the water supply unit 103, the water soap supply unit 104 and the hand washing and drying unit 105.

Referring to the operating state of the device, first hand into the hand washing and drying unit 105, the sensor 102 detects this and applies a detection signal to the control unit 106. The control unit 106 sequentially supplies water through the water supply unit 103 at predetermined time intervals, and supplies water soap through the water soap supply unit 104, and then washes and dries the soapy hand. The process will be carried out.

The conventional automatic washing device that is configured and functions as described above can be used by connecting to the sink's water supply device, so that it is possible to use convenience that does not need to separately carry soap or towels. There is an advantage that can not be installed in a simple portable sink. However, when the device is used for a long time, the same scale as water soap is trapped in the injection nozzle or supply pipe for spraying the water and water soap. If this scale continues to accumulate in the injection nozzle, the injection nozzle pipe will eventually be blocked and cause a failure, and if it accumulates on the inner surface of the supply pipe, it will not only act as an obstacle to smooth supply of water soap by reducing the tube diameter. However, there is a problem that acts as a detrimental factor in sanitation of hand washing.

In addition, the above apparatus has another problem that the manufacturing cost is high because the pump and the piping for the water supply and water soap supply must be provided, respectively.

Accordingly, the present invention has been made in order to solve the above problems, by using only one pump and a water storage pipe, water soap is sprayed together with water by the pumping force to pinch the nozzle and the supply pipe. It is an object of the present invention to provide an automatic washing apparatus and its operation control method which can prevent this and reduce the manufacturing cost.

In addition, the present invention is to be sprayed with water and water soap, and the drying process is performed automatically in one cycle to simplify the use of hand washing, and to reduce the consumption of water efficiently, soap or towel It is another object of the present invention to provide an automatic washing device and an operation control method thereof, which can be hygienically performed by hand washing without the necessity of an accessory such as the above.

In addition, since the present invention can be used only with the necessary power supply, can be installed directly in the wash basin, as well as providing an automatic washing device and its operation control method that can be used as a simple washbasin by moving to a place that is not equipped with water facilities. There is another purpose.

The water soap supply unit 5 is installed at a position higher than the water storage container 41, and a water soap supply container 61 for storing water soap; A water soap supply valve 62 is installed on the branch pipe of the water soap supply container 61 and the water and water soap supply pipe 7, and is opened and closed by a control signal of the controller 9 to inject water soap into the pipe 7. It is composed of

In the present embodiment, the water supply valve 44 and the water soap supply valve 62 are configured as a solenoid valve that is opened and closed for a predetermined time by receiving an open / close operation signal from the control unit 9, respectively.

The drainage portion 6 is located in an intermediate space of the main body 1, a recovery container 51 for recovering water discharged from the hand washing unit, and the first interlayer partition plate 1a of the main body 1. It is installed on the bottom surface is composed of a recovery container water level detection sensor 52 for detecting that the water in the recovery container 51 is filled by a predetermined level. In this case, when the hand-washed water is not stored in the recovery container 51, a drain pipe connector 53 is formed on the surface of the intermediate space of the main body 1 to immediately discharge it to the outside.

The water and water soap supply pipe (7) and the one end is connected to the discharge portion of the pump pump (8), the other end is connected to the injection vessel 41 of the hand washing unit and the main pipe (71); It includes a water supply pipe (72) connecting the suction port of the pump pump (8) and the discharge section of the water storage container (41). In addition, the first branch pipe (73) branched from the main pipe (71) toward the recovery container 51 side and the second branch pipe (74) branched from the main pipe (71) and connected to the water soap supply container (61) It is composed.

In the present embodiment, the main pipe 71 has a pipe 71a of P-turned shape by 360 ° in the vertical traveling direction of the pipe so that the water soap supplied from the water soap supply container 61 flows down by its own weight and is temporarily stored therein. On the P-turned pipe (71a) is provided with a non-return valve 77 for preventing the back flow of water soap. At this time, the non-return valve 77 may be made of any one of a check valve or a solenoid valve that is opened and closed by a control signal of the controller 9. Therefore, when water is pumped through the pump 8, the water soap introduced into the P-turn pipe 71a is pumped together by the pumping force of the water to be ejected to the spray nozzle 22a of the hand washing unit. Even if water soap is continuously discharged from the water soap supply container 61 due to the failure of the water soap supply valve 62, the water and the water soap are prevented from being flowed back to the water supply container 51 by the non-return valve 77. There is no fear of mixing.

On the other hand, the present invention shows a structure in which the support leg 81 is formed at the bottom of the main body 1, but is not limited to this, when the present invention is used as a simple portable washbasin, to facilitate the movement It is well known that the wheels can be used instead of the support legs 81. In addition, the control unit 9 has a built-in timer (not shown) for controlling the driving time appropriately during the operation control of the overall device.

It is well known that the present invention configured as described above can be used as an outdoor shower facility in addition to a toilet, and can also be provided in a water supply facility.

Referring to the operational state of the present invention in conjunction with the control flow chart of the control unit shown in Figure 6 as follows.

As shown in the figure, first, when the user turns on the power of the switch box 2, a control signal of the control unit 9 is applied to the water soap supply valve 62, the water soap supply valve 62 Is opened for a set time (2 seconds in this embodiment) to inject water soap into the main pipe 71, and the water soap supply valve 62 is blocked when the time elapses (S1, S2, S3, S4). The water soap introduced into the main pipe 71 flows down by its own weight and collects in the lower portion of the P-turn pipe 71a. In addition, when the user wants hot water, the hot water selection switch of the switch box (2) is turned on (on) to make it possible to receive hot water (S5).

After performing the above steps, the control unit 9 receives the detection signal from the water level detector 43 of the water storage container 41 to determine whether the water is stored as much as possible by hand washing, and if it is normal, hand washing And complete the initialization operation for drying (S6). If the water storage container 41 does not store as much water as possible for hand washing, the control unit 9 turns on the stop lamp and opens the water supply valve 44 from the direct water pipe. Replenish water (S7, S8). At this time, if the water level of the water storage container 41 is detected by the water level detector 43, after a predetermined time (10 seconds in this embodiment), the water supply valve 44 is blocked, when the water level is full, the ball top 45 ) To prevent oversupply of water. Then, in the place where the water supply facility is not equipped in the replenishment process of the water, the second interlayer compartment plate 1b is opened and water is directly replenished to the water storage container 41.

After the initialization operation is completed as described above, when the user puts his hand in the hand washing unit 3, the detection sensor 21 is activated to detect the input of the hand, the hand washing lamp is lighted by this signal (S9, S10). In this case, the user may put the hand in the washing unit and pull out, in this case, the hand input detection signal of the sensor 21 is blocked, the control unit after a predetermined time (3 seconds in this embodiment) Stop operation of equipment necessary for hand washing in (9).

When the step S8 is completed, the non-return valve 77 mounted on the P-turn pipe 71a of the main pipe 71 is opened, and the pump pump 8 is operated (S11, S12). The pump pump 8 sucks water contained in the water storage container 41 through the water supply pipe 72 to pump the water to the main pipe 71. The water pumped by the pump 8 is sprayed together with the washing water through the spray nozzle 22a through the spray container 22 while pushing up the water soap stored in the P-turn pipe 71a by the pumping force. . Accordingly, the user receives the washing water together with the water soap and performs hand washing at the same time. After performing step S12, the controller determines whether the set time (in this embodiment, the time required to rub the hand and completely remove the soapy time is set to about 15 seconds) has elapsed (S13). When it is determined that the set time has elapsed, the pumping pump 8 is stopped, whereby the water in the main pipe 71 flows back to the storage container by its own weight. After the operation of the pump pump 8 is stopped, if a certain time elapses, the check valve 77 is blocked, otherwise the pump pump is continuously operated (S14).

When the non-return valve 77 is blocked, the water sprayed into the injection nozzle 22a flows through the main pipe 71 and accumulates in the P-turn pipe 71a, but becomes a very small amount.

After performing the step S14, the brower 23 is operated to blow water for a predetermined time (7 seconds in this embodiment) while drying the water on the hand (S15, S16). At this time, when it is determined that the user is not completely dried in the process of drying the hand, the user may again put the hand into the brower 24. In this case, the control unit may detect the hand sensor 21 after a predetermined time (7 seconds) has elapsed. When the input of the hand is sensed), the brower is started again for the set time (S18). Then, when a predetermined time has elapsed since the operation of the brower 24 again, it is determined whether to turn off the power (S19). Otherwise, the power is turned off (off) to end the hand washing and drying process (S20).

In the present invention configured and operated as described above, the water soap and water supply process is always in a standby state when the power is turned on, and when a hand input is detected, the above series of cycles are performed. In this case, water soap is always stored in the P-turn pipe 71a of the main pipe 71. When the power is off, the water soap stored in the P-turn pipe 71a is completely consumed in the hand washing process. Thus, the water soap does not remain in the P-turn pipe 71a. There is no fear of time getting stuck.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have knowledge.

As described above, according to the present invention, by supplying water and water soap to the injection nozzle side at the same time by using only the water and water soap combined supply pipe, it is possible to reliably prevent the scale from being caught in the injection nozzle, and also the conventional water and By reducing the pumps installed in each one to supply water soap, and also reduce the number of pipes for supplying water and water soap to one, it is possible to reduce the manufacturing cost to a minimum.

In addition, the present invention can reduce the amount of water as possible by performing a cycle of washing and drying the hands within 30 seconds, and it is not only sanitary because no accessories such as soap or towels, but also always clean the surroundings of the toilet There are other effects that can be sustained.

In addition, according to the present invention, it is possible to operate the device using only the necessary power supply, and the wheel can be selectively installed in place of the support leg in the main body has yet another effect that can be used as a simple toilet in places where water facilities are not equipped Have
