Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a shoe washing machine that washes and rinses shoes such as sneakers.

(b) Prior Art As a conventional example, there is a washing machine that, when an unbalanced distribution of clothes in a tub is detected, performs a rinsing process at a water level higher than a set water level to correct the unevenness of the clothes. This is disclosed in Japanese Patent Application Laid-Open No. 59-8998.

(c) Problems to be solved by the invention When the technology described in the conventional example is applied to a shoe washing machine, the following problems arise.

(1) Shoes are cleaned by coming into contact with the brush on the brush shaft installed in the tank, so if a large amount of water is used, the shoes will float and the probability of contact with the brush will be reduced. Cleaning effectiveness decreases.

Therefore, in the rinsing process, if water is supplied to a higher water level than the set water level and then the brush shaft begins to rotate, as in the conventional example, the shoes will rise further and the contact with the brush will be reduced accordingly. This will reduce the

(2) In the rinsing process, the time required for cleaning is longer than when the brush shaft starts rotating from the set water level.

The present invention is intended to solve these problems in improving shoe cleaning machines.

(d) Means for solving the problem The present invention is for washing and rinsing shoes in a water-supplied tank, and includes a brush that is installed upright in the tank and has a disk-shaped substrate at the bottom. a main brush provided on a peripheral wall of the brush shaft so as to protrude vertically and laterally; an auxiliary brush provided on the substrate so as to protrude upward; a means for supplying water into the tank; a water level detection means for detecting a set water level for washing shoes and outputting a water level detection signal; a driving means for rotating the brush shaft;
The apparatus further includes a control section that starts driving the driving means and stops driving the water supply means after a predetermined time delay from the arrival of the detection signal.

(E) Function During the rinsing process, even though the water level is higher than the set water level, by rotating the brush shaft from the time the set water level is reached, that is, before the shoes float, the shoes can be cleaned. and brush,
In particular, it suppresses contact with the auxiliary brush from decreasing.

Furthermore, in the rinsing process, by rotating the brush shaft from the point when it reaches the set water level,
Rinsing ends faster.

(f) Example To explain based on the drawings, 1 is a machine frame of a shoe washing machine, inside of which is an outer tank 2 that serves as a water receiver, and a hanging rod 3...
It is supported elastically by Reference numeral 4 denotes an inner tank serving as a dewatering/cleaning tank, which is pivotally supported within the outer tank 2, and has a large number of dewatering holes in its peripheral wall and a balance ring 5 attached to its upper part. A brush shaft 6 is rotatably supported at the center of the bottom of the inner tank 4, and a disc-shaped base plate 7 is provided at the bottom, and main brushes 8 projecting horizontally outward are provided at the upper and lower positions of the shaft peripheral wall. On the substrate 7, auxiliary brushes 9 are provided to protrude upward at 90 degree intervals. The main brushes 8 may be arranged at 90 degree intervals to form a so-called cross shape, or may be arranged vertically in a spiral shape, and the auxiliary brushes 9 may be formed in a triangular, V-shape, I-shape, etc.

10 is a drive motor, which connects the inner tank 4 and the brush shaft 6.
are connected via a pulley, a belt, and a power transmission mechanism 11, and the brush shaft 6 is reversed at low speed during cleaning, and the inner tank 4 and brush shaft 6 are simultaneously rotated in one direction at high speed during dewatering.

Reference numeral 12 denotes a cover which covers a shoe entrance 13 formed above the inner tub 4, reference numeral 14 denotes an operating unit installed at the upper rear of the machine frame 1, reference numeral 15 denotes a water supply solenoid valve provided in the operating unit 14, reference numeral 16 denotes a water supply passage from the water supply solenoid valve 15 to the inner tub 4, reference numeral 17 denotes a drainage passage for draining water from the outer tub 2, and reference numeral 18 denotes a drainage solenoid valve interposed in the drainage passage 17.

Reference numeral 19 denotes a pressure type water level detection switch disposed within the operating section 14, which communicates with an air trap 20 formed at the bottom of the outer tank 2, and is activated to output a water level detection signal when a predetermined water level is reached. Note that this water level detection switch 19 can be replaced by a semiconductor pressure sensor or the like.

In order to control the drive motor 10, the water supply solenoid valve 16, the drain solenoid valve 18, etc. using water level detection signals and knob operations, a control device centered on a microcomputer (hereinafter referred to as microcomputer) 21 serves as an operation section. 14, and its control circuit diagram is shown in FIG. Further, FIG. 2 shows a block diagram for controlling various control sections constituted by the microcomputer 21 by the main control section 22 and a control program.

The operation of this embodiment will be explained below with reference to the flowcharts shown in FIGS. 3, 4, and 5. First, the shoe washing machine of this embodiment has a water supply 1 (detergent is added as necessary), as shown in FIG.
The steps of washing, draining, water supply 2, rinsing, draining, and dehydrating are executed in order.

Four types of reversal cycles are stored in advance in the memory (storage unit) 23 of the microcomputer 21, and the first to third reversal cycles are used in the washing process, and the fourth reversal cycle is used in the rinse process, respectively, under the reversal control of the microcomputer 21. 24. The stroke time is stored in the stroke counter 25 of the microcomputer 21, and the execution time of each reversal cycle is stored in the first to fourth reversal counters 26, 27, 28, 29.
and are counted down by the time signal of the timer 32. The first reversal period is 0.2
Second pause, 1 second drive for 5 minutes, second reversal period 0.2
Second pause, 0.8 second drive for 5 minutes, third reversal period 0.3
Second pause, 0.7 second drive for 2 minutes, 4th reversal period 0.4
It is executed for 2 minutes with a pause of 0.6 seconds and a drive of 0.6 seconds. That is,
The washing process is 12 minutes and the rinsing process is 2 minutes.

The operation of the reversing control unit 24 in the washing process is shown in the flowchart of FIG. 4, in which the washing is done strongly for the first 5 minutes, and the rest time is gradually lengthened to shorten the rotation (driving) time. Strong washing can cause the shoelaces to come undone and become entangled with the shaft 6, causing water to splash, or restricting the movement of the shoes and reducing the cleaning effect.
The rotation is shortened so that the shoelaces do not get tied to the shaft 6, and when the shoes are reversed, they come undone from the shaft 6, thereby preventing water from splashing and ensuring a cleaning effect. Incidentally, if the stroke is transferred with the 0 content of the third reversal counter 28, the stroke counter 25 can be omitted.

Next, when moving to the second water supply step, the microcomputer 21
The rinse water control section 30 operates to close the drain solenoid valve 18 and open the water supply solenoid valve 16, as shown in the flowchart of FIG. When the water level detection signal arrives, the inversion control section 24 shifts to the rinsing process.
causes the fourth reversal cycle to be executed, but the rinse water control unit 30 counts down the water supply 2 counter 31, which had been set to 45 seconds, based on the time signal of the timer 32, and also keeps the water supply solenoid valve 16 open. . The counter contents of the water supply 2 counter 31 are determined every 2 seconds, and after 45 seconds have elapsed, the rinse water control section 30 closes the water supply solenoid valve 16. In the rinsing process, the process counter 25 that counts down from the arrival of the water level detection signal or the fourth reversal counter 29 reaches 0.
It ends when the content is reached. In this way, since the amount of water is increased in the rinsing process, the rinsing effect is improved. In particular, when washing, a low water level (see WL in the figure) is used to ensure the cleaning effect, but the same water level switch is set to a high water level (see WL in the figure) for rinsing.
(Refer to RL) Can also be used as a switch. That is,
Two desired water levels can be obtained with one water level switch. In addition, there is no need to provide a water level switch exclusively for high water level for rinsing and waste time until reaching that water level.

Furthermore, in the fourth reversal cycle, the rest time is longer and the drive (rotation) time is shorter, so that the shoelace is extremely less likely to become entangled with the shaft.

(g) Effects of the invention In the configuration of the shoe washer according to the invention, although the rinsing process is carried out at a water level higher than the set water level, it suppresses the reduction in the cleaning effect due to shoes floating, and also improves the rinsing process. Substantial cleaning can begin before the execution water level is reached, reducing the total cleaning time.
