Abstract

PURPOSE:To enable correction of a stop position to a best position, by a method wherein during completion of dehydrating operation, it is decided by a position detecting means whether a stop position is situated in a position, and when it is not stopped in a position, control is made so that a rotary drum is rotated to a given position. CONSTITUTION:During completion of dehydrating operation, a means 15 to be detected is also stopped along with the stop of a rotary drum 4. With this state, when the means 15 to be detected does not coincide with a position detecting means 16, namely when a stop position is not a given position, the position detecting means 16 can not detect the magnetism of the means 15 to be detected, and no detecting signal is outputted. In this case, a brake mechanism 18 of the rotary drum 4 is released by an operation control circuit 17 to intermittently energize a motor 6 in a short period. The rotary drum 4 is slowly rotated, and when the position detecting means 16 detects the magnetism of the means 15 to be detected, the rotary drum 4 is braked for a stop. This constitution causes the stop position to form a position where a work to charge a finishing agent to a finishing agent containing case 12 and a work to mount and demount a lint filter 11 are easy to make, and improves facility.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a dehydrating and washing machine that is capable of correcting the stop position of a rotary tub at the end of a dehydrating operation.

(Prior Art) Conventionally, a washing machine with both a dehydrating and dehydrating function has been provided with a lint filter on the inner periphery of the upper part of a rotary tank for washing and dehydrating.
It has been proposed to provide a processing agent storage case that stores batch finishing agents and detergent, and to automatically introduce the finishing agent and the like into the tank from this processing agent storage case.

(Problems to be Solved by the Invention) By the way, at the end of the dewatering operation, the motor that drives the rotary tank is stopped, and a brake mechanism is activated to stop the rotation of the rotary tank.

Therefore, the stop position of the rotating tank varies and is not constant. Therefore, depending on the stopping position of the rotating tank, the lint filter may be in a position where it is difficult to attach or remove, or the processing agent storage case may be in a position that is difficult to attach or remove. The finishing agent, etc., is sometimes placed in a difficult position to accommodate, so it is not always easy to use. Note that when the rotary tank is stopped, the rotary tank is configured to be prevented from rotating by the brake mechanism, so that it is impossible for the user to manually rotate the rotary tank to correct the position of the lint filter or the like.

Although the present invention attempts to solve such problems, the first point is that the parts that are handled and operated by the user, such as the lint filter installed in the rotating tank, are not handled and operated by the user. To provide a dehydrating/washing machine which can automatically adjust the stop position of a rotary tub at the end of dehydrating operation to the best position so that it is at a place where it is easy to use, and improves usability.

[Structure of the Invention] (Means for Solving the Problems) The washing machine for dehydration 4 of the present invention includes a detection means provided in a rotating tub or a part that rotates in conjunction with the rotating tub, and a detection unit that detects the rotation of the rotating tub. A position detecting means is provided at a part that remains stationary even during dehydration, and the stop position of the rotary tank is determined at a predetermined position based on a signal from the position detecting means at the end of the dehydration operation. and a stop position control means for determining whether or not the rotary tank is located at the predetermined position and controlling the operation of the motor to rotate the rotary tank to the predetermined position if the stop position is not the predetermined position.

(Function) During the dehydration operation, the detected means also rotates as the rotary tank rotates, and when the dehydration operation ends, the detected means also stops at a position corresponding to the stop position of the rotary tank. In this stopped state, the position detection means outputs a signal according to the position of the detected means, and based on the output signal, the stop position control means determines whether or not the stop position of the rotating tank is at a predetermined position. When the stop position is not at the predetermined position, the motor is energized to rotate the rotary tank to the predetermined position.

(Example) Hereinafter, one example of the present invention will be described based on the drawings. First, in FIG. 1 showing the general structure of the entire machine, reference numeral 1 denotes an outer box of a washing machine for dehydrating and washing, and a water receiving tank 2 is suspended inside the outer box via an elastic suspension mechanism 3. Reference numeral 4 denotes a rotating tub for both washing and dehydration disposed within the water receiving tank 2, and a container-shaped stirring body 5 is disposed at the inner bottom thereof. 6 is a motor attached to the outer bottom of the water receiving tank 2, and its driving force is selectively transmitted to the dewatering shaft 8 of the rotating tank 4 and the washing shaft 9 of the stirring body 5 via the rotation transmission mechanism 7. It has become. Reference numeral 10 denotes a pumping channel provided in the rotating tank 4 so as to extend to the needle, and washing water is pumped into the pumping channel 1 by the pumping action of the pump blade 5a on the back surface of the agitator 5.
1 of this pumping channel 10: end outlet 1
The lint is returned to the rotating tank 4 through the lint filter 11 which is detachably attached to the lint 0a. - No.j112 is a finishing storage case detachably attached to the inner periphery of the upper part of the rotating tank 4 at a position opposite to the lint filter 11, and the finishing agent is applied from the input port 12a on the inner periphery of the upper end of the rotating tank 4. It can be put into the finishing agent storage case 12. The finishing agent stored in the finishing agent storage case 12 is automatically supplied into the tank by the centrifugal force accompanying the rotation of the rotating tank 4 during the dewatering process, and is then rinsed. 13 is a top cover attached to the upper end of the outer box l, and the opening 13a of this top cover 13 is
As shown in Fig. 2, due to the need to secure a space for installing the operation panel 14, the opening dimension in the front and rear direction is
i4's 1-Oi! It is narrower than the opening. Reference numeral 15 denotes a detection means fixed to the upper outer periphery of the rotating tank 4, and is composed of, for example, a permanent magnet.

Reference numeral 16 denotes a position detecting means fixed to the outer periphery of the water receiving tank 2, for example, a part that maintains a stationary state even when the rotating tank 4 rotates.
It is located at approximately the same height as 5. This position detection means 16 is
For example, it consists of a magnetic detection sensor, as shown in Figure 2.
When the detected means 15 is aligned with the position detecting means 16, the magnetism of the detected means 15 is detected by the position detecting means 16. In this case, at the position where the detected means 15 coincides with the position detecting means 16, the
The two-drug storage case 12 is located at the center on the left side of the opening 13a, and the lint filter 11 is located at the center on the right side. This is the position where it is easiest to both attach and detach the lint filter 11. Note that FIG. 1 shows the detected means 152 position detecting means 16. In order to show the relationship between the height positions of the lint filter 11 and the finishing agent storage case 12, all of them are shown for convenience, and the horizontal positional relationship is actually as shown in Figures 2 and 3. ing. The signal output from the position detection means 16 is then manually input to an operation control circuit 17 (see FIG. 1) provided on the lower surface of the top cover 13.

This operation control circuit 17 not only controls the washing, rinsing, and dewatering operation steps, but also functions as a stop position control means for correcting the stop position of the rotary tank 4 at the end of the dehydration operation.

The function of this operation control circuit 17 as a stop position control means will be explained. During the dewatering operation, the detection means 15 also rotates as the rotary tank 4 rotates, and when the dehydration operation ends, the detection means 15 also stops at a position corresponding to the stop position of the rotary tank 4.

In this stopped state, for example, when the detected means 15 does not match the position detecting means 16 as shown in FIG. 11 is not located at the center on both left and right sides of the opening 13a, the position detection means 16 cannot detect the magnetism of the detected means 15,
No detection signal is output from the position detection means 16. Based on the presence or absence of the detection signal from the position detection means 16, the operation control circuit 17 determines whether the stop position of the rotary tank 4 is at a predetermined position.
When there is no detection signal from the position detection means 16), the brake mechanism 18 of the rotary tank 4 is released and the motor 6 is energized intermittently in short cycles (see FIG. 4), causing the rotary tank 4 to rotate slowly.

As a result, when the rotating tank 4 rotates to a predetermined position and the detected means 15 coincides with the position detecting means 16, this position detecting means 16 detects the magnetism of the detected means 15, and this position detecting means 16 A detection signal is manually input to the operation control circuit 17. At this point, the power to the motor 6 is immediately cut off, and the rotary tank 4 is braked and stopped by the brake mechanism 18. In this way, the stopping position of the rotating tank 4 is corrected to a predetermined position, and as a result, the finishing agent storage case 12 is located at the center left side of the opening 13a, as shown in FIG.
The lint filter 11 is reliably positioned at the center on the right side. This state is the position where it is easiest for the user to both add the finishing agent to the finishing agent storage case 12 and attach/detach the lint filter 11, and it is easier to use than the conventional structure. .

In the embodiment described in 1-1, the lint filter 11 and the L agent storage case 12 were provided on the inner periphery of the upper part of the rotary tank 4, but the present invention can also be applied to an arrangement in which only one of these is provided. In addition, it can also be applied to those provided with a detergent storage case (detergent inlet), etc.

Further, in the above embodiment, the detection means 15 is provided in the rotating tank 4, but the detection means 15 may be provided in parts that rotate in conjunction with the rotating tank 4 (for example, the dehydration shaft 8, pulleys 19, 20, etc.). The position detection means may be provided in a stationary part (for example, the outer case 7as of the rotation transmission mechanism 7, the outer box 1, etc.) corresponding to the rotation transmission mechanism 7.

In addition, the present invention can be modified in various ways, such as detecting the detected means by the position detecting means, instead of using a magnetic detection method, for example, using an optical detection method.

[Effects of the Invention] As is clear from the above description, the present invention determines whether or not the stop position of the rotary tank is at a predetermined position based on the signal from the position detection means at the end of the dewatering operation, and determines whether the stop position is Since the configuration controls the operation of the motor to rotate the rotating tank to the specified position when it is not in the specified position, parts that are subject to handling and operation by the user, such as the filter installed in the rotating tank, can be handled and operated easily.・The stopping position of the rotary tank at the end of the dewatering operation can be automatically corrected to the best position (the predetermined position) so that it is located in a place that is easy to operate, which has the excellent effect of improving usability. .
