Abstract

PURPOSE:To enable a wash basin to be always kept clean by composing the wash basin so that the washing water of the almost same quantity as that of difference between a water discharging quantity and a reference washing water quantity may be fed to a basin surface, when the automatic water-discharging quantity is made less than the reference washing water quantity set to be increased in proportion to the discharging quantity of liquid soap. CONSTITUTION:When hands are extended to the lower side of a nozzle 18, then they are detected by a sensor 24, and by signal from a controller 60, a pump 32 is worked, and liquid soap in a tank 30 is discharged from the nozzle 18. After that, when the hands are put back, then the pump 32 is stopped, and the discharging of the liquid soap is stopped. After that, the hands are extended to the lower side of a water discharging port 20, then they are detected by a sensor 26, and by signal from the controller 60, a feed water valve 38 is opened, and from the water discharging port 20, water is discharged. Then, a reference washing quantity set previously to be increased in proportion to the discharging quantity of the liquid soap by the controller 60, and a water discharging quantity with automatic water-discharging, are compared with each other. Besides, when the water discharging quantity is made less than the reference washing water quantity, then the washing water of the almost same quantity as that of difference between both the quantities is fed to the basin surface of a wash basin 14 via a washing valve 54.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing control method for a washbasin having a mechanism for automatically flowing washing water onto the basin surface.

0002

[Prior Art] A washbasin includes a washbasin, a water spout and a soap discharge nozzle provided at the rear or side of the washbasin, and water is automatically spouted when a hand is put into the spout. Some washbasins are equipped with a control device for controlling the washbasin and a storage tank for storing water soap to be supplied to the discharge nozzle, which is installed inside the washbasin. This washbasin may also be provided with a hot air outlet for washing and drying hands.

[0003] The water soap stored in this tank is normally sent to a discharge nozzle by a pump.

0004

[Problems to be Solved by the Invention] Dirt adheres to the surface of the washbasin as the washbasin is used. In offices, etc., cleaning staff regularly clean the surface of the pot, but if this cleaning is infrequent, it will remain dirty and unpleasant for the users. Become something. In particular, when hands are washed with soap, soap components as well as dirt components adhere to the bowl surface, which tends to increase the dirt on the bowl surface.

[0005]

[Means for Solving the Problems] A cleaning control method for a washbasin with a washbasin cleaning device according to the present invention includes a washbasin, a water spout and a water soap discharge nozzle provided at the rear or side of the washbasin. , an automatic water spouting means for detecting a hand extended to the spout and spouting water; a tank installed inside the washstand for storing water soap to be supplied to the spout nozzle; and an inside of the tank. A washing basin washing control method comprising: a pump for supplying water soap to the discharge nozzle; and a wash basin cleaning device for supplying washing water to the basin surface of the wash basin, wherein the water soap is discharged by the pump. amount and the amount of water spouted by the automatic water spouting operation that follows it, and compare the standard amount of washing water set in advance to increase in proportion to the amount of water soap discharged and the amount of automatic water spouted by the automatic water spouting operation, If the automatic water discharge amount is less than the standard washing water amount, the washbasin washing device is operated so as to supply to the basin surface an amount of washing water that is approximately the same as the difference between the two.

[0006]

[Function] The washstand of the present invention can be used in the same manner as a normal washstand by spouting water by extending a hand to the spout or by discharging soap from the nozzle.

[0007] With this use, dirt adheres to the basin surface of the washbasin. This dirt adhesion is approximately proportional to the amount of soap used. In other words, the more water soap is used, the more soap components and dirt components washed off hands by the soap become, and the bowl surface gets dirty.

Therefore, in the present invention, in a series of hand washing operations including dispensing soap and subsequent discharging water (rinsing the soap from the hands), the standard amount of washing water is set so that it increases in proportion to the amount of soap used. Set it. If the actual amount of automatic water discharge is less than the standard amount of washing water, the washbasin is washed by supplying an amount of washing water approximately equal to the difference between the two to the basin surface.

[0009] In this way, the wash basin can be kept clean at all times by replenishing and flushing the wash water as needed.

[Embodiment] An embodiment will be described below with reference to the drawings.

FIG. 1 is a perspective view of a washstand according to an embodiment, FIG. 2 is a front view of the washstand, and FIG. 3 is a sectional view taken along line 3-3 in FIG. 2. Further, FIG. 4 is a control block diagram.

In FIGS. 1 and 2, a counter 12 is provided above a cabinet 10, and a washbasin 14 is provided on the counter 12. A back guard (standing wall) 16 is provided on the upper surface of the back side of the washbasin 14, and a discharge nozzle (hereinafter abbreviated as nozzle) 18 for discharging water soap is provided on the front side of the back guard 16. A water outlet 20 for discharging water for face washing, hand washing, etc., and a hot air outlet 22 for drying hands are provided. In addition, in this embodiment, the start and stop of the supply of soap, water, and hot air are automatically performed, and the nozzle 18
, near the water spout 20 and the air outlet 22, there are sensors 24, 26 for detecting hands extended downward, respectively.
28 are provided.

A tank 30 for storing soap to be supplied to the nozzle 18 is provided within the cabinet 10 . This tank 30 has a configuration in which a pump 32 is attached to the side, and the pump 32 is attached to a tube 34.
It is connected to the nozzle 18 via.

The water spout 20 is connected to a water supply valve 38 and a hot water mixing valve 40 via a pipe 36, so that hot water at a predetermined temperature can be supplied thereto. 42 is a water supply pipe, and 44 is a hot water supply pipe. Warm air can be supplied to the blower outlet 22 from a hot air generator 48 via a duct 46.

The washbasin 14 has a rim passageway 50, and a water injection hole 52 (FIG. 3) of the rim passageway 50.
Cleaning water can be supplied to the bowl surface of the washbasin 14 from the washbasin 14. Wash water can be supplied to the rim water passage 50 via a wash valve 54 and piping 56.

The bag guard 16 is provided with a sensor 58 for detecting the presence or absence of a human body in the front portion thereof.

Detection signals from the sensors 24, 26, 28, and 58 are input to a controller 60, and the controller 60 sends signals to the pump 32, water supply valve 38, hot air generator 48, and cleaning valve 5.
A control signal is output to 4.

In the washbasin equipped with the water soap supply device configured as described above, the following control is performed according to a program stored in the computer in the controller 60. That is, when a hand is put out below the nozzle 18, the sensor 24 detects the hand, the pump 32 is activated by a signal from the controller, and the water soap in the tank 30 is supplied to the nozzle 18. It is discharged from the tip of 18. When the hand is withdrawn, the pump 32 is stopped and the discharge of water soap is stopped. Similarly, when the hand is extended below the water spout 20 and the air outlet 22, water and hot air are blown out, and when the hand is withdrawn, the water and hot air are stopped.

After washing hands with soap, water is poured onto the hands to rinse the hands. demand. (Incidentally, a flow meter may be provided to directly determine the actual amount of water discharged.) Next, this actual amount of water discharged is compared with the reference amount of water for cleaning. This reference amount of washing water is set in advance so as to increase in proportion to the amount of water soap discharged, as shown in FIG. 5 in FIG. 5 shows the direct proportion between the amount of soap and the standard amount of washing water. In Figure 5, ■ indicates that the standard amount of water for washing is directly proportional to the amount of soap until halfway through, and after a certain level, it reaches a ceiling in order to save water.

[0020] ■ is such that the two curves have a correlation. Although not shown, the correlation may be a downwardly convex curve, contrary to ■ in FIG.

The standard amount of water for cleaning is determined from the relationship set as shown in FIG. pour it out. As a result, when a large amount of water soap is used, sufficient water is supplied to the pot surface to compensate for the amount of water soap used.
Soap components and dirt components are sufficiently removed, and the pot surface is always kept clean.

In this embodiment, when the sensor 58 no longer detects a human body, that is, after the human body leaves the cabinet 10, the insufficient cleaning water is drained. This prevents water from unexpectedly flowing out and surprising the user.

In the present invention, it is preferable to provide a large number of water injection holes in the rim passageway 50 as shown in FIG. The extending direction of the water injection hole may be set to be perpendicular to the vertical flow direction, so that the washing water swirls around the basin surface of the washbasin 14.

[0024]

[Effects of the Invention] As described above, in the washbasin cleaning control method of the present invention, water is reliably supplied to the bowl surface in an amount corresponding to the amount of soap used, and the bowl surface is cleaned. Therefore, it is possible to keep the basin surface always clean.
