Also, without using a sponge, cloth, etc., apply a liquid detergent (can be washed without rubbing) to the wall inside the bathtub with a spray bottle type container, and then lift up the dirt with the liquid detergent. Cleaners are cleaned using detergents that can be used to wash away detergent and dirt using a shower. However, in the former case, after applying the liquid detergent,
When wiping with a cloth, sponge, etc., it is necessary to bend while bending down, and when rinsing with a shower etc., water splashes around and wets workers' clothes, etc. It was very complicated, expensive, inefficient and uneconomical. In the latter case, when the detergent is sprayed on the wall surface in the bathtub, it is necessary to bend over the waist in the same manner, and depending on the method of spraying, there is a problem that spots are formed or the detergent is excessively used. Furthermore, when washing away with a shower etc. similarly to the above, there existed a problem that water scattered around and leaked the clothes of the worker, and the cost of water supply was required. Therefore, conventionally, there is a bathtub cleaning device that automatically sprays a detergent and then cleans the inside of the bathtub with tap water.
In that case, because of the water supply direct connection, a water pipe is required, and it is necessary to perform piping work in the bathtub, and the pipe becomes an obstacle during the original bathing, and in order to use a large amount of tap water,
Water costs were also incurred. In addition, the apparatus itself is large, and an installation space and the like are required. further,
A bathtub cleaning device that can be cleaned using the remaining hot water in the bathtub after bathing has also been proposed, but even in that case, piping etc. when installing the device is an obstacle, and when piping is provided outside the bathroom, Very large-scale construction such as plumbing is required.
Therefore, there has been a demand for a bathtub cleaning apparatus that is simple and reliable and does not need to be constructed when installing the apparatus, and has a high cleaning ability.

Start operation from the priming injection mode first, end operation in the rinsing injection mode last, and control to operate the detergent injection mode in any period between the first priming injection mode and the last rinsing injection mode The control means may be provided. With such a configuration, the bathtub 3
In washing 5, first, priming water is sprayed from the main body 1 floating in the bath tub 35 to wet the dried wall surface of the bath tub 35, and then, the cleaning liquid is sprayed from the main body 1 floating in the hot water in the bath tub 35 to spray the cleaning liquid. The dirt is removed by adhering to the wall surface, and then the bath water is sprayed and rinsed, whereby the bath tub 35 can be effectively cleaned.

Further, it is preferable to have means for stopping the injection of the detergent and the rinse for a certain period after the injection of the detergent. By adopting such a configuration, the washing is performed after a certain period of time since the detergent hits the dirt, and the cleaning effect by the detergent is more exerted than when rinsing immediately after spraying the detergent. You can do it.

It is also preferable to have an intermediate injection mode in which the injection pressure at the time of detergent injection or the injection pressure at the time of the rinsing injection is lower than the injection pressure. With such a configuration, in the intermediate injection mode, the jetting water does not fly to the bathtub 35 wall surface and hits the bathing water surface, and during the period between the detergent jetting and the rinsing jetting, the hair and the like are removed. It functions to keep dust away from the main body 1 and can be expected to quickly rise in water pressure in the next full-scale injection mode.

Further, it is preferable to provide a detergent injection pressure variable means for changing the injection pressure when the detergent is injected. Thus, the spray pressure is changed at the time of spraying the detergent according to the washing step, thereby enabling more effective washing with the detergent.

It is preferable to provide a rinsing injection pressure varying means for changing the injection pressure during rinsing injection. With such a configuration, the injection pressure of the bath water for rinsing is changed at the time of rinsing according to the washing step, thereby enabling more effective rinsing with the bath water.

Further, the detergent outlet 7 also serves as the bath water outlet 3, and the detergent injection pressure variable means for changing the injection pressure at the time of detergent injection comprises a rinse injection pressure variable means for changing the injection pressure at the time of rinse injection. It is preferable that they also serve. By adopting such a configuration, while achieving the dual use of members, the injection pressure is changed at the time of spraying the detergent according to the washing step, thereby enabling more effective washing with the detergent and rinsing at the time of rinsing spray. By changing the jet pressure of the bath water, more effective rinsing with the bath water is enabled.

The injection pressure adjusting means preferably has means for increasing the injection pressure with the passage of time. With such a configuration, the bathtub 35 can be removed with the drain plug removed.
When the main body 1 is washed while being floated in the bath water, the main body 1 gradually moves downward. At this time, as the injection pressure increases as time elapses from the start of cleaning, Even if there is an unwashed portion in the upper part of the bathtub 35, the washing liquid can be sprayed on the unwashed portion to be washed.

It is preferable to have a water detecting means 33 for detecting the presence or absence of water in the pump 5. With such a configuration, when there is no water in the pump 5, it is possible to perform control such that the water detecting means 33 detects this and prevents idling.

Further, it is preferable to have means for stopping the pump 5 when the drive current for driving the pump 5 becomes lower than the normal operation current. With such a configuration, the idle operation state (that is, a state in which there is no water in the pump 5) is detected by detecting the drive current for driving the pump 5, and the pump 5 is operated with the simple configuration during the idle operation. That can be stopped.

Further, it is preferable to have means for stopping the pump 5 when the drive current for driving the pump 5 continues to be lower than the normal operation current for a predetermined period. With such a configuration, in a case where water cannot be temporarily sucked up due to disturbance of a wave on the water surface of the bathtub 35, it is not detected and determined that the vehicle is running idle, and the normal operation is continued for a certain period of time. The pump 5 can be stopped only when it is determined that the pump is idle.

Further, it is preferable to have means for stopping the pump 5 when the drive current for driving the pump 5 becomes larger than the normal operation current. With such a configuration, a much larger load current flows than usual, such as when the motor is degraded due to hair or life and a motor lock occurs, and the pump 5 can be stopped by detecting this. Things.

Further, it is preferable to have a means for stopping the pump 5 when the state in which the drive current for driving the pump 5 exceeds the normal operation current for a predetermined period continues. With such a configuration, even if a load current larger than a normal load current temporarily flows due to dust or the like,
Since this is temporary and is immediately removed, such a temporary current increase is ignored by the circuit, and only the current increase for a certain period is detected and determined as a motor lock, etc.
Can be stopped.

Further, it is preferable to have operation maintaining means for maintaining the operation of the pump 5 for a certain time at the start of the operation of the pump 5. With such a configuration, for example, the detergent injection mode is a relatively short period, and if the pump 5 is not operated reliably during this period, the subsequent operation program or cleaning quality is affected. In such a case, by forcibly maintaining the operation of the pump 5 for a certain period of time, it is possible to prevent the subsequent operation program and cleaning quality from being affected.

Further, it is preferable to provide a float switch section 34 in the main body 1 and to provide a means for stopping the operation of the pump 5 when the water level of the float switch section 34 falls below a predetermined water level. With such a configuration, when the main body 1 reaches the bottom of the bathtub 35, the pump 5
Can be stopped.

It is preferable that a seat switch is provided at a position where the main body 1 can detect when the main body 1 reaches the bottom of the bathtub 35, and that the pump 5 stops driving when the seat switch detects the seat. With such a configuration, when the main body 1 reaches the bottom of the bathtub 35, the pump 5
Can be stopped.

It is preferable to provide a means for stopping the operation of the pump 5 when a certain period of time has passed in advance from the start of operation. With such a configuration, even when the drain plug is fitted into the drain hole again while the bathtub 35 is being washed by the main body 1 while the drain plug is pulled out from the drain hole and drained, a certain period of time is maintained. After the lapse of time, the inconvenience of automatically stopping the pump 5 and continuing the operation of the pump 5 can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings. 1 to 16 show one embodiment of the present invention. The bathtub cleaning device of the present invention includes a main body 1 that floats in bath water in the bathtub 35 to clean the inside of the bathtub 35, and a power supply section 37 that supplies power to the main body 1 and controls the operation of the main body 1. The main unit 1 and the power supply unit 37 are connected by a connection line 31 for supplying power to the main unit 1. The main body 1 is as shown in FIGS. 1 to 10. The outer peripheral portion of a housing 38 constituting the outer shell of the main body 1 has a hermetic structure, and an airtight closed chamber 2 is provided inside the main body 1.
7, the bath water does not penetrate into the hermetically sealed chamber 27 provided inside the main body 1, so that buoyancy can be generated in the housing 38 itself and the main body 1 can be reliably inserted into the bath water.
It is a structure that can float.

As shown in FIG. 5, a water supply port 2 is provided in a housing 38 below a bath water draft surface 49 when the main body 1 is floated in the bath water.
A pump 5 for sucking up bath water is provided. The pump 5 is a centrifugal pump and includes a pump case 5a, a rotary blade 23, a motor 24, a bell mouth 5b, and the like. To suck up the bath water, the motor 24 is rotated by the power supplied to the motor 24 through the connection line 31 from the power supply unit 37, and the rotating wings 23 fixed to the motor shaft are rotated to centrifuge the nearby bath water. A force is generated, and the bath water in which the centrifugal force is generated passes through the bottom surface of the bell mouth 5b and is supplied into the pump case 5a. In this way, the bath water is continuously supplied into the pump case 5a. It is structured to be supplied and sucked up.

The shaft of the motor 24 is waterproofed with a packing 39 to prevent the inside of the motor 24 from being flooded by the water pressure of the water sucked up by the pump 5 (see FIG. 8). The packing 39 has a structure that enhances the sealing performance when a water pressure is applied from the outside, so that the packing 39 is suitable for packing a rotating object such as the shaft of the motor 24.

As shown in FIG. 1, a rectifying rib 26 is provided near the bath water outlet 25 of the pump case 5a to attenuate the centrifugal force applied to the water. Here, the rectifying rib 26
Is provided for the following reason. That is, near the bath water outlet 25 of the pump case 5a, the centrifugal force given to the bath water causes the bath water to flow around the wall of the pump case 5a as shown in FIG. The wall 40a may be formed to block the bath water outlet 25, and an air pocket 40b may be generated at the center of the pump case 5a, so that the bath water may not be sucked up. In order to solve this, in the present embodiment, a rectifying rib 26 for attenuating the centrifugal force applied to the water is provided in the vicinity of the bath water outlet 25 of the pump case 5a, so that the bath at the time of pumping when the pump 5 starts up. By attenuating the centrifugal force of the bath water near the water outlet 25, there is no air pool at the center of the pump case 5a as shown in FIG. 17 (b), and the pump 5 can be sucked up more smoothly when it is started. It is.

As shown in FIG. 1, a filter frame 41a is detachably attached by screwing to a lower portion of the bell mouth 5b of the water supply port, and the filter 41b provided inside the filter frame 41a is connected to the bell mouth 5b. Filter frame 41a
Thus, the filter 41b is detachably held. The filter 41b is for removing impurities in the bath water, for example, hair, sebum, etc. when sucking up the bath water. In this way, by attaching the filter frame 41a in which the filter 41b is installed, the inside of the main body 1 is removed. There is no concern that large impurities enter the flow path, and the flow path can be prevented from being clogged. Further, since the filter frame 41a, the filter 41b, and the bell mouth 5b have a detachable structure, maintenance is performed when the filter 41b is clogged, and even when impurities are entangled with the rotating blade 23, the motor shaft, etc. The maintenance can be done easily by removing.

Next, the bath water sucked from the pump 5 passes through the bath water outlet 25 of the pump 5 in the main body 1.
It flows into the detergent tank 6 from the pump connection pipe 42. A fixed amount of a detergent for washing the inside of the bathtub 35 is previously supplied to the detergent tank portion 6, and a mixed liquid in which the bath water and the detergent are mixed for a certain time immediately after the bath water flows into the detergent tank portion 6. Is pushed out to the outlet 12 of the detergent tank portion 6. Therefore, in this embodiment, the detergent tank 6 also serves as the mixing unit 8 for mixing the bath water and the detergent. When the detergent in the detergent tank section 6 is pushed out by the bath water and the detergent runs out, the bath water passes through the detergent tank section 6 and flows to the outlet 12 of the detergent tank section 6.

That is, a mixture of bath water and detergent flows from the outlet 12 of the detergent tank section 6 to the injection port 3 of the nozzle section 4 for a certain period immediately after the pump 5 is started.
Thereafter, the bath water sucked from the pump 5 flows directly into the outlet 12 of the detergent tank 6. Therefore, in the present embodiment, the detergent tank section 6 has both a storage function for storing the detergent and a mixing function for mixing the bath water and the detergent.

The inlet 9 of the bath water from the pump 5 to the detergent tank 6 (that is, the connection between the pump connection pipe 42 and the detergent tank 6) is connected to the detergent tank 6 as shown in FIG. It is provided so that it may be located higher than the water surface 10 when the water is charged. By providing the inlet 9 above the water surface 10 when the detergent is charged into the detergent tank 6, the detergent flows back to the pump 5 through the pump connection pipe 42 when the detergent is charged. Therefore, the detergent can be reliably stored in the detergent tank 6.

Further, as shown in FIG. 18A, when the outlet 12 of the detergent tank 6 is provided below the water surface 10 when the detergent is poured into the detergent tank 6, the detergent tank 6 When bath water A flows into the bath 6 from the inlet 9 of the bath water, the bath water does not flow into the detergent tank 6 because the air in the detergent tank 6 does not escape. The bath water A may not flow to the outlet 12 either. For this reason, in the present embodiment, FIG.
As shown in the figure, the position of the outlet 12 of the detergent tank portion 6 is provided so as to be higher than the water surface 10 when the detergent is injected, and the bath water A is introduced from the inlet 9 of the detergent tank portion 6. When air flows, first, air in the detergent tank 6 flows into the outlet 12 of the detergent tank 6, and then the detergent and the bath water A are mixed. It flows out to the exit 12.

The detergent tank 6 has a detergent inlet 15 for introducing detergent and a cap 16 for opening and closing the detergent inlet 15. The cap 16 is provided with a water pressure of the bath water sucked up from the pump 5. It has a closed structure so that it can withstand. Since the opening and closing structure of the cap 16 can be easily opened and closed and has a sealing function, the bayonet method (when the cap 16 is rotated left or right, the cap 16 rises and the sealing is released, and the right or left side is released. When the cap 16 is rotated in the direction, the cap 16 descends to form a sealed structure, but it is not necessarily limited to this. When charging the detergent into the detergent tank 6, the cap 16 is first opened, the detergent is charged to a certain volume, and the cap 16 is closed again. The cap 16 is connected to the main body 1 by a connecting member 17 such as a connecting string, and can prevent the cap 16 from being lost when the cap 16 is opened and a detergent is supplied.

Next, the bath water (or mixed liquid) flowing into the outlet 12 of the detergent tank section 6 passes through the nozzle connection pipe 43,
It flows to a nozzle unit 4 attached to the upper surface of the main body 1, is injected from an injection port 3 provided in the nozzle unit 4, and reaches a wall surface in the bathtub 35. Nozzle part 4
Is rotatably attached to the main body 1 above the bath water draft surface 49 when the main body 1 floats on the bath water (rotatably in the circumferential direction of the main body 1).
Is rotatable in the circumferential direction of the main body 1, so that when the bath water (or mixed liquid) is sprayed into the bath tub 35, it can be surely sprayed evenly on the wall in the bath tub 35.

Here, FIG. 7 shows a structure in which the nozzle portion 4 is rotatably connected to the main body 1.

8, the detergent B for one time can be supplied to the detergent tank 6.

Next, still another embodiment of the present invention will be described with reference to FIG. In the present embodiment, an injection pump 71 capable of injecting external air into the second detergent tank 18 is provided. Also in this embodiment, similarly to the above, the second detergent tank 18 to the detergent tank 6

This embodiment does not require a cylinder device or an infusion pump as in the above-described embodiment, so that the structure can be simplified and the space can be saved.

Next, the control circuit 52 of the power supply unit 30 in the present invention will be described.

In FIG. 28, reference numeral 24 denotes a motor for driving the pump 5 for sucking water. The control circuit 52 includes switching means 62 such as a power transistor, a relay, a triac, and an FET for switching driving of the motor 24, a CPU 63 for controlling operation of the main body 1, a stabilized power supply for driving the CPU 63 and the circuit. A circuit 64, a cleaning switch 54 which is a start switch having a timing for driving the motor 24,
A washing lamp 56 and the like, which are display means for displaying the operation state of the motor 24, are provided. Further, when the state of water changes due to a change in the pump 5 in which the motor 24 is built, the drive current of the motor 24 is monitored. In addition, there is provided an empty operation detecting means 65 for outputting a signal urging the CPU 63 to change the overall operation.

FIG. 29 shows an operation time chart of one embodiment of the present invention. When the cleaning switch 54 is turned on, first, the detergent injection mode is activated, and the detergent is injected for a fixed time. Thereafter, a rinse injection mode is finally provided, and control is performed by the CPU 63 as a control means so as to rinse and wash the portion with the detergent. During that time, there may be any injection mode. By having the first and last modes, the bathtub 35 can be reliably washed by the main body 1 of the present invention.

Next, FIG. 30 shows a time chart of another embodiment of the present invention. When cleaning the bathtub 35, a mode in which pre-washing is performed in advance before spraying the detergent is added. By simply pre-washing and leaking the dried wall surface of the bathtub 35, the effect of detergent cleaning can be expected more reliably. That is, as shown in the time chart shown in FIG. 30, when the cleaning switch 54 is turned on, the preliminary water cleaning mode is first activated to wet the wall surface of the bathtub 35,
The detergent spray mode is activated and the detergent is sprayed for a fixed time. After that, control is performed so that the rinse injection mode is finally set to perform the rinsing of the portion covered with the detergent. During that time, there may be any injection mode. An effective operation mode other than the first, last, and intermediate modes may be included.

Next, FIG. 31 shows a time chart of still another embodiment of the present invention. In the present embodiment, a complete injection complete stop period is provided after the detergent injection mode, and the rinse injection mode is controlled to be activated after the complete injection complete stop period. Things. By providing a complete injection stop period for a certain period after the detergent injection mode in this way, the detergent is injected by the operation of the detergent injection mode to hit the dirt, and after a certain period of time, it is better to rinse and wash. Also, the cleaning effect of the detergent can be exerted and the stain can be removed well. According to an example of the present embodiment, the detergent spray is about 5
Second, the injection complete stop period after the detergent injection is about 30 seconds. Of course, each of the above times can be arbitrarily set according to the conditions of the main body 1 and the bathtub 35.

Next, still another embodiment of the present invention will be described. In the present embodiment, when the cleaning operation is performed by pressing the cleaning switch 54, which is a start switch, the water pressure that is equal to or lower than the injection pressure during the cleaning injection or the rinsing injection is set during an arbitrary period between the first mode and the last mode. The operation of the intermediate injection mode for injecting bath water is performed. For example, as shown in the flowchart of FIG. 32, between the operation in the detergent injection mode and the operation in the rinse injection mode,
An operation in the intermediate injection mode is provided. By performing the operation of the intermediate injection mode in which the bath water is injected at a water pressure equal to or lower than the injection pressure at the time of the washing injection and the rinsing injection, the injected bath water A is operated in the intermediate injection mode as shown in FIG. Bathtub 3
Water does not fly to the wall of No. 5 and hits the surface of the water, so that a quick rise in water pressure during the next full-time injection mode can be secured, and debris such as hair during the full-time injection mode stop period Has an effect of not approaching the main body 1.

Next, another embodiment of the present invention will be described with reference to FIG. In the present embodiment, a detergent injection pressure variable means 66a for changing the injection pressure at the time of detergent injection is provided. That is, the control circuit 52 of the power supply unit 30 is provided with a detergent injection pressure variable means 66a such as a resistance load, and C
By changing the resistance value by the PU 63, the applied voltage of the motor 24 can be changed to change the detergent injection pressure at the time of detergent injection.

Next, still another embodiment of the present invention will be described with reference to FIG. In the present embodiment, the rinsing injection pressure varying means 66 for changing the injection pressure during rinsing injection
b. That is, the control circuit 52 of the power supply unit 30 is provided with a rinsing injection pressure varying means 66b such as a resistance load.
Is provided, and the resistance value is varied by the CPU 63 so that the applied voltage of the motor 24 can be changed to change the rinse injection pressure at the time of the rinse injection.

Next, in the embodiment shown in FIG.
In the case where the detergent injection and the rinse injection are shared by one common injection port 3 (that is, the detergent injection port is also used as the bath water injection port 3), the detergent injection pressure variable shown in FIGS. Means 66a and rinsing injection pressure varying means 66b
This is an example in which a single injection pressure variable means 66 is used for both. In this apparatus, one injection pressure variable means 66 can change the injection pressure during detergent injection and the injection pressure during rinse injection.

FIG. 37 shows a control example in which the injection pressure variable means 66 (or the detergent injection pressure variable means 66a or the rinse injection pressure variable means 66b) is varied with time by the CPU 63. For example, FIG. ) Body 1 like
38 is obtained from the injection pressure at the time when
(B) As shown in FIG.
5 is set so that the injection pressure when it reaches the lower part of FIG. As a result, the injection pressure increases as the main body 1 moves downward, so that the remaining portion to be washed can be completely washed away. In FIG. 37, the graph indicating the time and the injection pressure is in a proportional state, but may be a staircase state line.

Next, still another embodiment of the present invention will be described. The present embodiment is characterized in that a water detecting means 33 for detecting water in the pump 5 is provided.
The presence of water in the pump 5 is detected by the water detecting means 33, and when there is no water, the operation of the pump 5 is stopped and the pump 5 is stopped.
To prevent idle running. Therefore, in the present embodiment, the idling operation detecting means 65 is constituted by the water detecting means 33.

Here, in the embodiment shown in FIG. 39, an example is shown in which water detecting means 33 is provided in the main body 1. The water detecting means 33 is, for example, an electrode type and has a weak current if water is present. Flow (weak current output is CP
U63).

Another example of the water detecting means 33 for detecting the water in the pump 5 is shown in FIG. FIG. 40 shows the power supply unit 37.
In this example, the water detecting means 33 is provided on the control circuit 52 side, and the pump 5 is stopped when the driving current for driving the pump 5 becomes lower than the normal operating current. In the present embodiment, the shunt resistor 68 and the comparator 69 are provided in the control circuit 52 to constitute the water detecting means 33. The drive current flowing through the motor 24 normally generates a load while sucking water. And a large current is flowing. If the water runs out and the water is not sucked up, the load on the motor 24 is reduced and the driving current is reduced.
This is detected by a shunt resistor 68 provided in the circuit, and is sensed as a voltage difference. The load becomes lighter than a threshold value set in advance by a comparator 69 and the current drops. When the input voltage of the comparator 69 falls below the threshold value, the CPU 63 In this method, the pump 5 is controlled to stop when the drive current for driving the pump 5 becomes lower than the normal operation current.

Next, still another embodiment of the present invention will be described with reference to FIG. In the embodiment shown in FIG. 40 described above, when a period during which the drive current of the motor 24 cannot temporarily draw up water due to, for example, turbulence on the water surface of the bathtub 35 occurs, the water detection unit 33 detects that there is no water. In some cases, it is erroneously determined that the vehicle is in the idle operation state, and the operation program scheduled thereafter cannot be executed. In order to avoid this, in the present embodiment, FIG.
As shown in FIG. 1, a time constant circuit 70 using the water detection means 33 and CR is provided on the control circuit 52 side of the power supply unit 37. The time constant circuit 70 using the CR is, for example, an integration circuit, and does not stop the pump 5 unless the load current value falls below a predetermined period. In other words, the pump 5 is controlled so as to stop when the driving current for driving the pump 5 is lower than the normal operating current for a predetermined period of time.

As shown in FIG. 42, the output of the comparator 69 shown in FIG. 41 can be processed by the CPU 63 using software. For example, the idle operation prohibition mode in FIG.
If set within 63, the motor 24 is driven for the first time,
It is possible to avoid an erroneous detection of idle operation due to a state in which water is not yet wound up by the pump 5 in an initial state where the water in the bathtub is sucked up.

Incidentally, as an application of the configuration in which the shunt resistor 68 and the comparator 69 are provided in the control circuit 52 as shown in FIG. 40, the following control may be further performed. That is, control is performed so that the pump 5 is stopped when the drive current for driving the pump 5 becomes larger than the normal operation current. For example, when the motor 24 is degraded due to hair or life and a motor lock occurs, a load current much larger than a normal load current flows. This is detected by a shunt resistor 68 shown in FIG. 40, and is taken as a voltage difference.
When the input voltage of the pump 9 exceeds the threshold value, a signal is output to the CPU 63 to control the pump 5 to stop when the drive current for driving the pump 5 becomes larger than the normal drive current.

As shown in FIG. 41, the shunt resistor 68 and the comparator 69 are provided in the control circuit 52 of the power supply unit 37.
The following control may be further applied as an application of the one provided with the time constant circuit 70 using the CR and the CR. That is, when the motor 24 is operating in a normal state, a load current larger than a normal load may temporarily flow due to dust or the like. At this time, an increase in the current is detected by the shunt resistor 68 shown in FIG. However, the temporary current increase is ignored by the circuit, and if the current increase does not continue for a certain period of time, it is not determined that the drive current has increased beyond the normal current, and in this case, the control to stop the pump 5 is performed. Instead, the pump 5 is controlled so that the pump 5 is stopped only when the current increase continues for a certain period.

Next, still another embodiment of the present invention will be described.

Next, still another embodiment of the present invention will be described with reference to FIG. In the present embodiment, when the operation of the motor 24 is started by pressing the washing switch 54, which is a start switch, a forced operation mode for forcibly maintaining the operation for a certain period after the start is set. For example, the detergent injection mode is a relatively short period of time, during which the operation program and cleaning quality will be affected if the motor 24 is not operated reliably.
