Abstract

PURPOSE:To detect the vibration of a water tank without needing any special device, but with simple construction and high reliability by providing an unbalance detecting device for detecting the vibration of the water tank in dehydration. CONSTITUTION:When any large deviation of clothes is not found in dehydration, the vibration of a water tank 18 is small and the variation of tension of a wire 47 having one end fitted to the water tank 18 is few. Then, a limit switch 54 of a rotation detector is not operatively opened and closed. When the deviation of the clothes is large, the water tank 18 is vibration with a large amplitude, and the tension of the wire 47 having one end fitted on the water tank 18 is substantially varied. Thus, a guide pulley B50 is vibrated and the limit switch 54 of the rotation detector repeats the opening and closing operations. Thus, a controller 70 judges the clothes to be deviated and stops the dehydration. After water supply, agitation, drain and correction of the deviation of clothes, the dehydrating process is resumed. Thus, an unbalance detecting means is realized by the limit switch 54 of the rotation detector.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a washer/dryer that can continuously carry out processes from washing, rinsing, dehydration to drying.

Conventional technologyConventional. , a washer/dryer having a structure as shown in FIGS. 9 and 10 has been considered. That is, a water tank 2 is rotatably supported within the washer/dryer main body 1 by a horizontal shaft 3, and a rotary tank 4 is rotatably installed inside the water tank 2 via a rotary shaft 5. - The lower part of the water tank 2 is equipped with a pulsator, a drive switching device N6 for the rotating tank 4, and a motor 7a that drives the rotating shaft 5. The rotating shaft 5 and the motor 7a are connected via a belt. A moving motor 7b is fixed to the main body 1 near the end of the horizontal shaft 3, and a pinion gear 9 that meshes with a worm gear 8 driven by the moving motor 7b is fixed to the horizontal shaft 3. When the worm gear r8 rotates, the pinion gear 9 is driven, and the horizontal shaft 3 rotates in response to this, and the water tank 2 rotates around the horizontal shaft 3. A fan 10 used during drying is connected to a duct 12 via a heater 11 on the outside of the lower part of the water tank 2, and the duct 12 communicates with the inside of the water tank 2. Reference numeral 13 denotes a balance detection device, which is composed of a switch that opens and closes according to the vibrations of the water tank 2, and operates to stop the dewatering when the vibrations of the water tank 2 are large during dehydration.

In the above structure, first, when the aquarium 2 is in the straight-on state, insert clothes for the aquarium from the upper part of the main body 1 and turn on the power. The washing, rinsing, and spin-drying steps are performed with the water tank 2 in a vertical position as shown by the solid line in FIG. 9 and in FIG. 10. If the clothes are shifted in the rotating tub 4 during washing, the vibrations of the water tub 2 will increase during dehydration. At this time, the switch of the unbalance detection device 13 opens and closes, thereby detecting the unevenness of the clothes, and stopping the dehydration before the vibration becomes dangerous. When the last dewatering process is completed, the pinion gear r9 is driven by the rotation of the moving motor 7b, that is, the rotation of the worm gear 8, and the water tank 2 is brought into a horizontal state, and the process shifts to the drying process. This state is shown by the two-dot chain line in FIG. 9, and in the aiiB drying process, the rotary tank 4 is rotated and the fan 10 and heater 11 are energized to perform drying. When the drying process is completed, the moving motor 7b is driven again to set the water tank 2 in a vertical position, and the dried clothes are taken out from the upper part of the main body 1, thereby completing the series of washing and drying courses.

Problems to be Solved by the Invention In the washer/dryer with the above structure, an amplifier is installed to detect the vibrations of the water tank in order to prevent large vibrations from occurring during spin-drying and creating a dangerous situation when clothes are piled up in the rotating tank. It is necessary to provide a balance detection device. In addition to the unbalance detection device, a rotation detection device for detecting the horizontal and vertical states of the tank is also required.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to realize an unbalance detection device that detects vibrations of a water tank during dewatering with a simple configuration and high reliability.

unbalance detection means for detecting a large unbalance during dewatering; The unbalance detection means detects by opening and closing the limit switch in a predetermined manner during dehydration.

Function: The washer/dryer of the present invention has the above-mentioned configuration, so that when the clothes are lopsided in the rotating tank and a large vibration occurs during dehydration, the wire attached at one end to the water tank receives tension corresponding to the vibration, and the rotation detection device is activated. The guide booby swings, and the limit switch that detects the vertical position of the tank opens and closes. In this way, the unbalance detection means is operated by detecting the opening/closing operation of the limit switch of the rotation detection device. This makes it possible to detect vibrations of the water tank during dewatering with a simple configuration and high reliability without requiring any special equipment.

Reference numeral 73 is composed of a one-chip microcomputer, and has a storage section, an input section, an output section, and an arithmetic control section, and stores the settings selected at the operation input stage 71, and performs pre-stored operations based on this. Washing and
It is a microcomputer that controls operations such as rinsing, and is 74 to 78
The washing motor, dehydration motor,
Washing, rinsing, spin-drying, and drying are carried out by driving and controlling water supply and drainage means, heaters, blowers, turning devices, etc., and washing execution means 74, rinsing execution means 75, dehydration execution 1,000 stages 76, drying execution 1,000 stages 77, This is a turning device 78.

Next, the operation in this embodiment will be explained with reference to the flowchart shown in FIG. Operation begins at step 79. After input/output initialization is performed in step 80, selection of execution of each course of washing, rinsing, spin-drying, and drying is inputted from the operation input stage 71. When there is an input, the selected content is accepted in step 81 and stored in the storage means. When the start input is received in step 82, the washing and drying operation is started in step 83. First, in step 83, a washing/rinsing process is performed according to the selection input. FIG. 1 shows the state of the water tank during the washing, rinsing, and spin-drying processes.

During the washing/rinsing process, the washing shaft 24 of the rotary tub 21 is located perpendicularly to the installation surface of the main body A14, and at this time, the pulsator 22 is connected to the washing shaft 24 via the mechanical part 23 and is driven by the washing motor 29. It rotates in a predetermined forward and reverse cycle.

When the washing/rinsing process is completed and dehydration is selected in step 84, the dehydration process is started in step 85. During the dewatering process, the rotary tank 21 is moved to the dewatering shaft 2 by the mechanical part 23.
5 and rotates at a high speed of about 800 rpm to perform dehydration. At this time, in step 86, if there is no large deviation of the clothes, the vibration of the water tank 18 is small, and the fluctuation of the tension of the noyer attached at one end to the water tank 18 is also small. The limit switch 54 of the laundry rotation detection device does not open or close, and the control device 70 determines that the clothes are not lopsided and performs the dehydration process. When the dehydration for a predetermined period of time is completed in step 87, a drying process is performed in steps 88 to 91 according to the selection input, and the series of courses is completed in step 92.

On the other hand, in step 86, if the clothing is largely biased, the water tank 18 vibrates with a large amplitude, and the tension of the wire attached to the water tank 18 at one end changes greatly. Therefore, the guide pulley B50 vibrates and the limit switch 54 of the rotation detection device repeats opening and closing operations.

As a result, the control device R 7 0 detects that the clothes are on one side.
1, stop dehydration in step 93, and proceed to step 9.
After water is supplied, stirred, and drained in steps 4 to 97 to correct the unevenness of the clothes, the dewatering process is restarted in step 85.

In this way, the limit switch of the rotation detection device can realize an unbalance detection means.

When the dehydration process is completed and the drying process begins, the water tank l
Perform 8 horizontal turns. The rotation operation is performed by connecting the rotation clutch 45, driving the rotation motor 44, and winding up the wire 47 by the winding boob 51 attached to the rotation reduction mechanism 46, so that the water tank 18 gradually rotates around the rotation shaft 38. Perform a turn. When the water tank 18 becomes horizontal and the limit switch 855 is activated, the rotation motor 44 is stopped. Then, the guide pulley A49 is moved by the tension of the wire 47, and the limit switch A49 is moved by the tension of the wire 47.
54 is canceled. The above operations are from step 88 in FIG.
It is 89.

Next, in the drying process, the rotating clutch 45 is released and only the blower 42 is driven by the rotating motor 44. At the same time, the drying motor 32 is driven, and the speed reduction device 33 and the drying pulley 34 are connected by the clutch. The rotation of the drying motor 32 is decelerated to about 6 Orpm by the speed reduction device 33, and the torque is amplified. The rotating tank 21 is connected to the belt 835 by the drying motor 32.
Rotation is started at a predetermined rotation speed of about 6 Orpm through the rotary tank 2l, and the clothes inside the rotating tank 2l are transferred. The drying air heated by the heater 57 is blown into the rotating tank 21 to dry the clothes. The heater 57 is provided near the opening at the top of the water tank 18, and the heated drying air is immediately blown into the rotating tank 21, so that very efficient drying can be achieved. The above operation is step 90. Next, when the drying process is finished, the rotating tank 21 is stopped and the rotating clutch 45 is connected.
The rotation motor 44 rotates in the opposite direction and sends out the wire 47 wound around the winding/boot 51. When the water tank 18 becomes vertical, the tension of the wire 47 becomes weaker and the guide pulley A49 is returned to its original position by the spring A52, operating the limit switch A54 and stopping the rotating motor 44. The above operations are steps 91-92. In this way, a series of steps from washing to drying are performed.

As described above, the present invention provides a control device that performs washing, rinsing, and spin-drying processes in a water tank in a substantially vertical state, and a drying process in a water tank in a flat state of 1 The rotation detection device is equipped with a rotation detection device that detects the state and an unbalance detection device that detects a large imbalance during dewatering. This is done using a moving guide pulley and a limit switch operated by the guide pulley.The unbalance detection means detects when the clothes are unbalanced in the rotation tank by the predetermined opening/closing operation of the limit switch during dewatering. When large vibrations occur during spin-drying, the wire attached at one end to the water tank receives tension in response to the vibrations, causing the guide pulley of the rotation detection device to swing, detecting the vertical position of the water tank, and opening/closing the mitt switch. Let's do it. In this way, the unbalance detection means is operated by detecting the opening/closing operation of the limit switch of the rotation detection device. This makes it possible to detect vibrations in the aquarium during dewatering without the need for any special equipment, and with simple precautions and with high reliability.
