Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a hand washing machine that washes hands by discharging soap liquid and hand washing water.

<Prior Art> Conventionally, as this type of hand washing machine, there is one disclosed in Japanese Utility Model Application Publication No. 50-60243, as shown in FIG. 13, for example.

To explain the structure shown in FIG. 13, a soap liquid container 101 and a washing water container 102 are housed in a casing 103 and arranged above the hand washing machine 104, and the soap liquid is dispensed based on the sensing of the user by the sensing section 105. By electrically operating supply units 106 and 107 provided downstream of container 101 and washing water container 102, respectively, soap solution and hand washing water are intermittently discharged in a predetermined order.

However, the soap liquid container 101 in FIG.
Since the remaining amount of soap liquid inside the casing 103 cannot be seen from outside the casing 103, it is difficult to know when to replenish the soap liquid, and if the soap liquid is discharged even though the remaining amount of soap liquid is small, the inside of the soap liquid container 101 may be damaged. Not only will the soap liquid not be discharged if the soap liquid container 101 becomes empty, but if the pipe near the supply section 106 located on the downstream side of the soap liquid container 101 becomes empty and air enters, the amount of soap liquid remaining will be small. Because of this, it dries and solidifies easily,
If this air enters the supply section 106, it may cause malfunction, and if air enters the supply section 106, the soap liquid adhering to the supply section 106 will solidify.
There was a problem in that even if soap liquid was replenished into the soap liquid container 101 after that, the supply section 106 did not operate and the soap liquid was not discharged.

<Problem to be solved by the invention> The problem to be solved by the invention is to notify the user when the amount of soap liquid remaining is low.

<Means for solving the problems> The technical means taken by the present invention to solve the above problems are a soap liquid discharge device that discharges soap liquid into the hand wash basin, and a hand wash water discharge device that discharges hand wash water. A hand washing machine equipped with a device is characterized in that a water level detector is installed in the soap liquid container of the soap liquid discharging device, which outputs an output when the remaining amount of soap liquid reaches a set water level and lights up a warning lamp. That is.

<Function> This invention notifies the user when it is time to replenish the soap liquid by outputting an output from the water level detector and lighting up a warning lamp when the remaining amount of soap liquid in the soap liquid container reaches the set water level. It is.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG.
It is housed in a casing 3 together with a soap liquid discharging device 2 and a hand washing water discharging device 6, and a ball cleaning device 7 and a drying device 8 are also provided inside the casing 3.

The washbasin 1 is made of ceramics, synthetic resin, etc. and is shaped like a mortar and has a ball portion 1a inside, and is opened diagonally upward from the top surface to the middle of the front surface, and has a drain port (not shown) in the bottom surface. 1) and connect the drain pipe 1b to it.

The casing 3 has an opening 3 for manually inserting the ball part 1a of the washbasin 1 in its front part corresponding to the opening.
The opening 3a is smaller than the opening of the ball part 1a, and the opening edge thereof is bent inward and extends inside the water passage rim 1c, and the casing 3 and the washbasin 1 are connected to each other.
A cylindrical portion 3b is formed that hides the gap between the two.

The soap liquid discharging device 2 includes a soap liquid container 2a and a soap liquid supply pipe 2 connected to the downstream side of this container 2a.
b, a supply part 2c such as an electromagnetic pump or a solenoid valve provided in the middle of the soap liquid supply pipe 2b, and a soap liquid discharge nozzle 2d installed at the tip of the soap liquid supply pipe 2b so as to face into the ball part 1a. Then, the soap liquid is supplied to the soap liquid container 2 by the operation of the supply section 2c.
The soap liquid is sent from a to a soap liquid discharge nozzle 2d, and is discharged from the nozzle 2d to be used for hand washing.

In the illustrated example, the supply section 2c is constituted by an electromagnetic pump, and the electromagnetic pump 2c sends an operation start signal to a control section based on a user's detection by a sensing section 9 (described later) or a push of a soap switch 5b on an operation panel 5. 4 for a predetermined period of time, e.g. 1 to 2.
It is designed to operate for seconds.

The soap liquid container 2a is a cylindrical or box-shaped hollow body made of synthetic resin or the like, and is attached to the casing 3.
The soap solution supply pipe 2b is connected to the outlet 2a1 opened on the lower surface of the mounting plate 3c, which is installed and fixed on the upper surface of the mounting plate 3c, which is located above the washbasin ₁ in a substantially horizontal manner. is equipped with a water level detector 2e.

The water level detector 2e consists of a float part 2e ₁ that moves up and down as the water level of the soap liquid rises and falls, and a switch part 2e ₂ that switches on and off as the float part 2e ₁ moves up and down. The switch section _2e2 is electrically connected via the control section 4 to a warning lamp 5a provided on an operation panel 5 disposed on the front surface of the casing 3.

In this embodiment, the float part 2e ₁ is formed in the shape of a vertically elongated hollow rod, and its upper part is inserted into a through hole 2a ₂ bored in the upper surface of the soap liquid container 2a so as to be vertically movable. A shielding part 2e ₁₁ is provided protrudingly,
The shielding portion 2e ₁₁ is located between the light emitting element 2e ₂₁ and the light receiving element 2e ₂₂ of the photoelectric sensor constituting the switch portion 2e ₂ .

The light emitting element 2e ₂₁ and the light receiving element 2e ₂₂ are respectively arranged to face the U-shaped switch mounts 2a ₃ protruding from the upper surface of the soap liquid container 2a. When the soap liquid is fully filled, the infrared light emitted from the light emitting element 2e ₂₁ is blocked by the shielding part 2e ₁₁ and is not received by the light receiving element 2e ₂₂ and no signal is output to the control unit 4. When the water level of the soap liquid falls and reaches the set water position, the shielding part 2e ₁₁ moves downward, the light receiving element 2e ₂₂ receives the infrared rays from the light emitting element 2e ₂₁ , and outputs a signal to the control unit 4. I'm starting to do that.

The control unit 4 includes the electromagnetic pump 2c and the water level detector 2.
It is electrically connected to the switch section _2e2 of e and the warning lamp 5a provided on the operation panel 5, and is also electrically connected to the power supply, so that the warning lamp 5a and the electromagnetic pump 2c are energized by the signal from the switch section _2e2. ON/OFF control.

That is, the soap liquid discharging device 2 is controlled as shown in the block diagram shown in FIG. and outputs it to one input terminal of the AND circuit 4c, and energizes and operates the electromagnetic pump 2c by the operation of the electromagnetic pump drive circuit 4b,
Nozzle 2d that discharges soap liquid from soap liquid container 2a
send to

When this is repeated many times, the water level of the soap liquid gradually decreases and approaches the set water level. When this water level reaches the set water level, the water level detector 2e outputs a signal to the warning lamp drive circuit 4d to activate it, thereby energizing the warning lamp 5a and lighting it up, and the other input terminal of the AND circuit 4c also outputs a signal and starts a timer circuit 4e or a count circuit with the output from the AND circuit 4c.

The timer circuit 4e or counting circuit counts the time or number of times the electromagnetic pump 2c is activated after the warning lamp 5a lights up, and when this reaches a set amount, the timer circuit 4e or the count circuit counts the time and starts the operation of the gate circuit 4a.
From then on, even if an operation input signal is output to the gate circuit 4a, the electromagnetic pump drive circuit 4
Do not activate b.

Therefore, after the warning lamp 5a lights up, only a predetermined amount of soap liquid is discharged from the soap liquid container 2a, and if the predetermined amount is set so that the inside of the soap liquid container 2a does not become completely empty, Malfunction of the electromagnetic pump 2c due to solidification of the soap liquid can be prevented.

Furthermore, if the user notices the warning lamp 5a and replenishes the soap liquid into the soap liquid container 2a, the signal output from the water level detector 2e disappears, and the signal is reset from the output reversing circuit 4f to the timer circuit 4e or the count circuit. A signal is output to return it to its initial state and open the gate circuit 4a.

Note that the water level detector 2e is not limited to the one described above, and modified examples thereof are shown in FIGS. 8 to 11.

The one shown in Fig. 8 is a float part 2e ₁ formed in an annular shape.
is vertically movably inserted into _a column 2e ₃ vertically erected on the lower surface of the soap container 2a, and a reed switch constituting the switch section 2e ₂ is provided below the column 2e 3. When the soap liquid falls to the set water level, the float part _2e1 moves down, and the reed switch _2e2 is turned on by the magnet _2e4 provided in the float part _2e1 , and a signal is sent to the control part 4. Output.

The one shown in Fig. 9 is a float part 2e ₁ formed in an annular shape.
is vertically movably inserted into a support _2e3 vertically disposed on the upper surface of the soap liquid container 2a, and a reed switch 2e which is located below the support _2e3 and constitutes a switch part _2e2 . ₂ , when the soap liquid falls to the set water level, the float part _2e2 moves down and the reed switch _2e2 is activated by the float part _2e1 .
It becomes ON state and outputs a signal to the control section 4.

In the one shown in FIG. 10, the upper end of the float part 2e ₁ formed in the shape of a vertical bar is inserted into a through hole 2a ₂ formed on the upper surface of the soap liquid container 2a so as to be vertically movable, and the upper end of the float part 2e ₁ is inserted upwardly and downwardly. Position switch part 2
The lever of the limit switch that constitutes e ₂ is arranged so that it can be moved up and down, and when the soap liquid falls to the set water level, the float part 2e ₂ moves down and the lever of the reed switch 2e ₂ moves down by its own weight, releasing it from the terminal. When you leave it, it turns on and outputs a signal to the control unit 4.

In the one shown in FIG. 11, the upper end of the float part 2e ₁ formed in the shape of a vertical bar is inserted into the soap liquid container 2a so as to be vertically movable, and a shielding part 2e ₁₁ is provided protruding from the upper surface of the soap liquid container 2a. The light emitting elements 2e ₂₁ , 2e ₂₃ and the light receiving elements 2e ₂₂ , 2 of the photoelectric sensor that make up the switch part 2e ₂ are mounted on the switch mounting base 2a ₃ .
E ₂₄ is arranged in two stages, upper and lower, facing each other.
When the soap liquid first falls to the first set water level, the shielding part 2e ₁₁ moves down and the light receiving element 2e ₂₂ receives the infrared rays from the upper light emitting element 2e ₂₁ , outputting it to the control unit 4 and outputting it to the warning lamp 5a. lights up, and when the soap liquid further descends and reaches the second set water level, the light receiving element 2e ₂₄ receives infrared rays from the lower light emitting element 2e ₂₃ , outputting it to the control unit 4 and operating the electromagnetic pump 2c. to stop.
