Description

Washing machine {WASHING MACHINE}

The present invention relates to a washing machine, in particular a pulsator type washing machine.

Generally, a washing machine is roughly divided into a pulsator type and a drum type. The pulsator method rotates the pulsator arranged in the washing tank, generates "water flow" by the rotation thereof, and contaminates by mechanical action such as friction or vibration and chemical action by detergent. The washing tank (with a pulsator) is rotated to dehydrate the washed clothes, and centrifugal force is used. In addition, drying of the clothing after dehydration rotates the pulsator or the washing tank itself, blowing in a warm air in a washing tank.

On the other hand, the drum type rotates a drum (corresponding to a washing tank) provided with a rotating shaft in the horizontal direction, and utilizes the mechanical action and the chemical action by the detergent when the laundry falls in the drum by the rotation. The drum is rotated and the centrifugal force is used for dewatering the garment. In addition, drying of clothing after dehydration rotates the drum, blowing in a warm air in a drum.

Therefore, the washing machine is, of course, required to improve the cleaning performance to remove the dirt attached to the clothing, that is, to improve the average "cleaning performance to remove the contamination" and to reduce the "deviation of the contamination free", and to dry the clothes. The improvement of the performance, ie, the "drying stains of clothing" and the "prevention of thermal damage", "acceleration of drying" and "reduction of power consumption" is called for.

However, in the conventional pulsator type washing tank, the rotating shaft is perpendicular to the bottom (vertical direction), and the rotating surface is parallel to the bottom (horizontal direction), so that the pulsator (or the washing tank itself) rotates in the forward or reverse direction. It is. For this reason, the water flow generated by the pulsator concentrates in the center portion, so that the entanglement of the rags and the flow or movement in the vertical direction are less likely to be formed, so that the effective washing is not performed and the washing force may be lowered.

Therefore, in response to the improvement of the cleaning performance, for example, in the pulsator method, based on the known knowledge that "the cleaning performance is improved by cleaning the washing tank in an inclined state, and the variation of the omission of the contamination is also small". The washing machine provided with the washing tank fixed obliquely is disclosed (for example, patent document 1, patent document 2).

In addition, in response to a request for rapid drying, for example, in a washing machine of a pulsator type that can perform a washing cycle from a washing stroke to a drying stroke, the washing tank is tilted only for the drying stroke, and the clothes are driven. The invention which improves a drying performance by applying is disclosed (for example, patent document 3).

Disclosure of the Invention

Problems to be Solved by the Invention

However, since the washing machines disclosed in Patent Documents 1 and 2 are to be cleaned in an inclined washing tank, the washing performance is improved, but there are the following problems.

(A) When drying the garment, the rotational weave of the washing tub is not vertical in the direction of gravity (since the rotational axis is not vertical), thus inherently a force of `` centrifugal force + gravity component '' or `` centrifugal force-gravity component '' There is a problem in that the rotation is unbalanced structure.

(B) In addition, when the washing tank or the pulsator stops rotating, clothing tends to be biased toward one side of the inclined washing tank, which makes it difficult to execute the dewatering stroke. That is, since the rotating surface of the washing tank is not vertical in the direction of gravity (since the rotating shaft is not vertical), when the clothes are biased to one side, the centrifugal force on the one side where the clothes are biased increases, and the "clothing weight (water containing ) Increases the centrifugal force + gravity component "or" the centrifugal force-gravity component on the non-cloth side ", and unbalance is encouraged, and vibration and noise increase.

On the other hand, since the washing machine disclosed in Patent Literature 3 is dried by tilting the washing tank and drying the rotary shaft vertically, unbalance due to the gravity component as described in (a) does not occur, but the clothes are not in the washing tank. In the case where the washing is finished in the biased state, there is a problem that unbalance occurs in the rotation of the washing tank.

(C) In addition, since the washing machines disclosed in Patent Literatures 1 to 3 are all washed in an inclined washing tank, there is a problem that the amount of clothes that can be put in is limited. In other words, the inclined washing tank has a smaller amount of water that can be stored than the non-tilting washing tank, and the amount of clothes which can be washed by this water also naturally decreases.

(D) In other words, when a predetermined amount of clothing is to be washed freely, a washing tank that is tilted and washed becomes larger in size than a washing tank that is washed without tilting, so that a washing machine equipped with such a large washing tank increases its external dimension. You can talk about the problem.

In addition, in the washing machines disclosed in Patent Documents 1 to 3, the housing is a schematic rectangular parallelepiped, and a clothes outlet for introducing and removing clothing is formed on the upper side of the schematic rectangular parallelepiped, and the edge of the top opening of the inclined washing tank ( In particular, since the front edge is located in the rear position from the clothes ejection port, there is a problem that it is bad to use in the operation of loading and removing the clothes. That is, since a washing machine of a pulsator type washing machine having a predetermined capacity or more has a large washing tank, the clothes outlet is located at a considerable height from the installation surface (same as the bottom surface) of the washing machine. You had to look into the bottom of the tub from the drawer, raise your feet to reach out, or bend over. Such poor use is one of the causes of lowering the product competitiveness, especially in a washing machine having the user as a housewife.

This invention is made | formed in view of the above, and it aims at providing the washing machine which ensures favorable washing | cleaning performance, prevents rotational unbalance of the washing tank at the time of drying, and is easy to use.

Means to solve the problem

The washing machine according to the present invention includes a housing,

A washing tank for freely rotating and freely storing the clothes in the housing, and putting the clothes in, and washing and dewatering the clothes;

Jaw tilting means for tilting and standing up the washing tank;

Has control means for controlling the landscape driving means,

It is characterized in that the inclination angle of the washing tub can be changed in accordance with the stroke from the start to the end of the stroke selected by the user.

For example, a washing stroke (including a rinsing stroke in an upright state) in which the garment is washed while the washing tank is inclined, a dehydration stroke in which the washing tank is dehydrated in an upright state, and in a state in which the washing tank is inclined. Eject strokes from which the garment is taken out may be executed independently of each other, or such strokes may be optionally executed continuously.

In addition, in this invention, since a "washing tank" contributes to washing and dehydration, it is the same as "dehydration and washing tank", and when contributing to drying separately (for example, when warm air is supplied), "drying and dewatering and Washing tank ”.

In addition, in this invention, "washing clothes" points to one or both of "washing" or "rinsing." Therefore, it includes the case where the rinse is inclined at the second inclination angle after being washed at the inclination angle at the first inclination angle, or the rinse in the upright state after the washing is inclined at the predetermined inclination angle.

In the present invention, "upright" refers to a posture perpendicular to the bottom of the washing machine, that is, a vertical name posture, and "tilt" refers to a posture inclined by a predetermined angle with respect to the vertical direction of the bottom of the washing machine. .

In addition, in the present invention, "clothing" is not limited to literally "clothing", but includes daily necessities such as bedclothes, towels, curtains, and the like. It also includes synthetic resin products.

Effects of the Invention

Therefore, the washing machine concerning this invention has the following effects.

(A) Since the washing tank is inclined before washing or the washing tank is inclined while washing, washing performance is improved.

(B) Since the washing tank is dehydrated in a state of standing upright before dewatering, the unbalance of rotation is reduced or the occurrence of unbalance of rotation is prevented.

(C) When the clothes are taken out of the washing tank, the washing tank is in an inclined state, so that the taking out operation becomes easier, and the feeling of use is improved.

The drive mechanism may not be electrically driven.

(Washing tank)

Since the washing tank 5 contributes to washing, rinsing, dehydration, and drying of the put clothes, the washing tank 5 is also called a washing / dehydrating tank or a washing / dehydrating / drying tank. The washing tank 5 is disposed freely in the water tank 2. That is, since the water tank 2 is fixed to the tilt table 20 and the tilt table 20 is tilted, the washing tank 5 tilts together with the water tank 2 (it will be described in detail separately). The washing tank 5 is a tubular shape in which the top surface is opened and the bottom surface is closed, and a plurality of water passages for dewatering are formed in the side surface (not shown).

Moreover, inside the bottom face of the washing tank 5, the pulsator 4 which stirs the injected clothes and the injected water (henceforth "washing water") is arrange | positioned freely. Hereinafter, in order to distinguish it from the rotation of the washing tank 5, the rotation of the pulsator 4 is called "swing".

A balancer 6 is provided around the top surface opening of the washing tub 5. Therefore, the range enclosed by the inner periphery of the balancer 6 is an opening part, which contributes to putting in or taking out clothes. Moreover, since the water tank cover 7 is provided in the water tank 2 which accommodates the washing tank 5, the upper end surface of the balancer 6 is covered by the water tank cover 7, and is concealed.

And the ventilation duct 16 which communicates with the said casing discharge port, stands up along the outer wall of the water tank 2, and opens to the opening edge of the water tank 2 is provided. Moreover, since the blowing duct 16 has flexibility near the communication part with a casing discharge port, it is tilted with tilting of the water tank 2. In addition, when such a drying means is provided in the tilting belt 20, flexibility is not required for the blowing duct 16.

In addition, the warm air heated by the heater 17 contributes to drying of the clothes in the washing tank 5 and is then discharged to an exhaust duct (not shown). And after performing "water cooling dehumidification" which waters toward this discharged warm air, it is sent to the ventilation duct 16 again, and circulates.

(Mirror mechanism)

FIG. 2 is a detailed view of the tilt mechanism of the tilt table in the washing machine shown in FIG. 1. In FIG. 2, the tilt table 20 is freely tilted at a position (hereinafter referred to as a tilt point) 20a near the front surface of the horizontal stand 19.

In addition, the tilting motor 21 is attached to the horizontal stage 19, and the pinion 22 is fixed to the rotating shaft of the tilting motor 21. As shown in FIG. In addition, the rack 23 is freely provided on the tilting table 20, and the pinion 22 and the rack 23 are engaged with each other. Therefore, when the rack 23 pushes up the tilting platform 20 by the rotation of the tilting motor 21, the tilting table 20 tilts the tilting point 20a as the tilting center (same as the rotational center). In the figure, the washing tank 5 (before inclination) which stands up is shown by the dashed-two dotted line.

That is, when the tilting platform 20 tilts toward the front by the angle θ, the front side of the upper end opening of the water tank 2 is advanced from the position "2c" to the position "2b" by the horizontal distance "D", and the bottom face From the distance "C" to the height of the distance "B", descending by the vertical distance "E".

In addition, in the figure, the upper edge of the front surface of the housing 1 (when the upper edge is not horizontal, the lowest position of the upper edge) is shown by the position "1a."

Further, a pressing means (for example, a compression spring, hereinafter referred to as a "spring") 24 is tensioned between the horizontal stand 19 and the tilting stand 20 to tilt the tilting stand 20. It is pressurized in the direction to make.

Moreover, the inclination angle detector (not shown) which detects the inclination angle of the tilt table 20 is provided, The detection result of this inclination angle detector is input into a control means (not shown), and the control of the tilt motor 21 etc. is carried out. Contribute to.

In addition, the format of the inclination angle detector is not limited, and the angle or distance is continuously detected within the tilt range, or a predetermined angle (for example, the maximum tilt angle or the minimum tilt angle (such as horizontal)). It may be to detect what is in. It may also be a non-contact type (optical sensor, magnetic sensor, etc.) or a contact type (so-called touch sensor).

Furthermore, tilt lock means (not shown) is provided to lock tilt of the tilt table 20. The type of the tilt lock means is not limited, but directly restrains the tilt of the tilt platform 20 itself, restrains the rotation of one or both of the pinion 22 or the rack 23 (for example, advancing and retreating). Possible locking pins, etc.), or may electrically lock the tilting motor 21.

Incidentally, the tilt mechanism is not limited to the one shown, but instead of the rack 23 freely lifting and lowering, a large pinion engaged with the pinion 22 is provided on the inclined platform 20, or a solenoid is substituted for the tilt motor. May be used. Alternatively, a worm gear mechanism may be used instead of the pinion / rack mechanism. When the worm gear mechanism is provided, the installation of the tilt lock means can be omitted.

As another tilting mechanism, as shown in Figs. 13 and 14, the water tank 2 is suspended and supported by a rod 3 that hangs at four corners of the upper portion of the housing 1. In 3), the hanging bar 3 provided in the rear side of the water tank 2 may be made to top and bottom. This is because when the hanging rod 3 on the rear side of the water tank 2 is slid upward, the water tank 2 is inclined forward (see FIG. 14), and when the hanging rod 3 is slid downward, the water tank is returned. (2) returns to the upright state (see FIG. 13). This is conventionally used in which the hanging rod 3 and the water tank 2 are slidably connected at the connecting portion 24. The hanging rod 3 and the water tank 2 are slidably connected to the front and rear directions of the water tank 2 by sliding the rod 3 up and down. Tilting becomes possible. The slide in the up-down direction of the hanging rod 3 is performed by the driving unit 25, and the driving unit 25 may be any type as long as the hanging rod 3 is vertically moved in the longitudinal direction, and the hanging rod 3 A structure adapted to the driving unit 25 may also be provided on the) side to move the hanging rod 3 up and down. For example, the female thread part is formed in the hanging rod 3, and the drive part 25 is a structure which rotates a male thread part, and the rotational motion of the male screw of the drive part 25 is transmitted to the female thread part of the hanging rod 3, and hangs. The rod 3 may slide upward or downward to incline and upright the water tank 2. In addition, in the case of the tilting mechanism which slides the hanging rod 3 up and down and tilts the water tank 2, the detection means (not shown) which detects the length adjustment position (position of the hanging rod 3) of the hanging rod 3 When the inclination angle of the water tank 2 is provided and the inclination angle of the water tank 2 is provided, the water tank 2 can be controlled to a desired inclination angle.

Or equivalent to the take-out stroke), FIG. 4 shows the lid 8 and the cover 9 closed (corresponding to the cleaning stroke).

In FIG. 3 and FIG. 4, since the tilt table 20 is tilted toward the front side, the position of the front side of the upper end opening of the washing tub 5 is advanced to the position "2b", and the height of the distance "B" from the bottom surface is shown. It is. At this time, the upper edge of the front surface of the housing 1 (when the upper edge is not horizontal, the lowest position of the upper edge) is the position "1a", and the distance "A" is the height of the distance "A" from the bottom surface. Is smaller than or equal to the distance " B ".

That is, the upper edge 1a of the front surface of the housing 1 is lower than the position 2b of the front side of the upper opening part of the washing tank 5. In addition, as described above, the position 2b on the front side of the upper end opening of the washing tub 5 is lowered while advancing by tilting, so that the user working on the front surface touches the inside of the washing tub 5. In addition, since the upper opening of the washing tub 5 faces the user's line of sight by tilting, it is easy to look into the bottom of the washing tub 5. Therefore, clothing is easy to put in and take out.

In FIG. 6, the washing machine 100 is capable of executing a washing stroke, a rinsing stroke (hereinafter, may be referred to as a "washing stroke" in combination with the washing stroke and a rinsing stroke), a dehydration stroke, and a drying stroke. It is possible to set a driving course. There is also an "initial stroke" before the driving course, and a "boil stroke" after the driving course.

(i) In the initial stroke, when the power switch is turned on (0N), the washing tank 5 is inclined.

(Ii) When the washing operation is included in the set driving course, when the amount of clothes put is large, when the washing tank 5 is standing up, the "upright washing" is performed and the amount of clothes put is small. The "tilt washing" which wash | cleans in the state which inclined the washing tank 5 is performed.

(Iii) When a rinse stroke is included in the set driving course, the "standing rinse" which washes in the state in which the washing tank 5 was upright is performed irrespective of the quantity of clothes put into it.

(Iv) When a dehydration stroke is included in the set driving course, "upright dehydration" for dewatering in the state in which the washing tank 5 is upright is performed regardless of the amount of clothes put into it.

(v) In the case where the set driving course includes a drying stroke, when the amount of clothes put in is large, when the washing tank 5 is standing up, the "upright drying" to be dried is performed and the amount of clothes put in is small. The "slope drying" which dries in the state which inclined the washing tank 5 is performed.

(Iii) In the boil stroke, the power switch is automatically turned off (0FF), and the washing tank 5 is tilted. And when the cover is closed (corresponds to the completion of the removal of the clothing), the washing tank 5 is upright, and the series of strokes is completed.

Next, the flow of control will be described based on the time chart.

(S1: clothing input)

In FIG. 7, the washing tub 5 is tilted at an inclination angle of 20 °, for example, after waiting for turning on the power supply 0N of the washing machine 100, and after the completion of tilting, the lid 8 and the cover 9 are closed. ) Cover lock is opened. Then, since the lid 8 and the lid 9 can be opened and closed freely, the user can open the lid 9 (the lid 8 also works in conjunction with each other) as appropriate and put the clothes into the washing tank 5. Can be. At this time, since the washing tank 5 is inclined, as described above, the introduction of clothes is facilitated.

In addition, when the washing tank 5 of the washing machine 100 is turned off (0FF) in an inclined state, the tilt of the washing tank 5 is mechanically locked, and the inner cover 8 and the cover ( Since 9) is free to open and close, the user can appropriately open the outer cover 9 (the inner lid 8 is also linked to open) and inject clothes into the washing tank 5. At this time, since the washing tank 5 is inclined, as described above, the introduction of clothes is facilitated.

In addition, once the cover 9 (or cover 8) is locked, the cover lock is not released unless the power switch is turned off (0FF) or the entire stroke of the set driving course is completed. Do not.

(S3: load detection)

Next, the load amount (weight of clothes put in) is detected by a well-known method. That is, after starting the rotary motor 11 and rotating the pulsator 4 by a predetermined amount, the inertia of the pulsator 4 after stopping the rotary motor 11 (pulsator 4) is stopped. ) The weight of clothing (value that can be converted into "load amount") is detected by the rotation amount.

(S4: Determination of water injection amount and inclination angle)

And based on the detection result of the said load amount, the water injection amount and the inclination angle (the center of gravity of an axis | shaft are equal to the angle which makes a perpendicular direction) of the washing tank 5 in a washing | cleaning stroke are determined.

For example, when the diameter is about 540 mm and the water tank 2 of about 540 mm in depth, when the weight of the detected clothing is about 6 kg or less, the inclination angle is 30 degrees. Then, as will be described later, the washing performance can be improved and a sufficient amount of water can penetrate the clothes.

For example, when the weight of the detected clothing exceeds about 6 kg, the inclination angle is 0 °. That is, the washing tank 5 is made upright without inclining, ensuring an amount of water sufficient to penetrate the clothes, and preventing the water in the washing tank 5 from overflowing during washing (hereinafter referred to as "upright washing method"). Reference).

(S5: water injection and tilting)

Then, water injection and tilting are performed based on the above determination. That is, the tilting motor 21 provided in the horizontal stand 19 is driven, and the tilting stand 20 to which the washing tank 5 is fixed is tilted. That is, the control means outputs the tilt tilt command to the tilt motor 21. Then, the inclination angle detector detects that the inclination angle θ is 20 ° (θ = 20 °), or the inclination angle detector (corresponding to the position sensor) provided at the position of the inclination angle 20 ° operates. At one point, the tilt motor 21 is stopped. That is, the control means outputs the tilt stop command to the tilting motor 21.

In addition, after water injection is finished (after the open water supply valve is closed), washing is started while washing is started, but water is poured in parallel with water or after water is finished. You may also do it.

In particular, in the case of the upright washing method, it is preferable to inject water after the end of tilting so that water does not overflow from the water tank 2 or to end the tilting before the water injection amount is near (see Fig. 8).

(S6: washing)

In the cleaning, the tilt lock mechanism is operated while the washing tank 5 is inclined at an inclination angle of 20 °, and in the locked state, the pulsator 4 is rotated at low speed. "Improvement of the washing | cleaning performance" by washing by tilting the washing tank 5 is demonstrated separately. And since the completion | finish of a washing | cleaning stroke is close, the rotation motor 11 is decelerated and stopped while opening a drain valve and draining.

(S7: Kyungdong)

The tilt lock mechanism is opened at the point where the drainage is finished, and the tilt of the washing tank 5 is started to stand upright. That is, the tilt motor 21 provided in the horizontal stand 19 is driven again, and the tilt table 20 to which the washing tank 5 is fixed is tilted.

And the inclination angle detector corresponds to the point which detected that the inclination angle (theta) became 0 degree ((theta) = 0 degree), or the inclination angle detector (upper limit sensor) provided in the position of the inclination angle 0 degree. ), The tilting motor 21 is stopped, and the washing tank 5 is perpendicular to the floor (same as vertical).

In addition, the tilt lock mechanism may be opened and the tilting of the washing tank 5 may be started before the drainage ends. For example, even when a driving course including no rinsing stroke is set, washing of the clothes at the end of the washing stroke can be reduced by performing washing for a predetermined time in the washing tank 5 in an upright state before the washing stroke is completed. Therefore, the unbalance of rotation in the dehydration stroke immediately after that can be reduced.

(S8: Rinse)

The rinsing is performed (locked) by the tilt lock mechanism in the state where the washing tank 5 is upright. In Fig. 7, the rotary motor 11 is rotated at low speed while the water is supplied, and after the predetermined amount of water is supplied, the water supply is stopped, but the rotation is continued, and then the rotation motor 11 is decelerated and stopped immediately before the end of the rinsing. In addition, although the drain valve is shown to open and to drain, this invention is not limited to this control.

For example, inserting the dehydration stroke which rotated the washing tank 5 at high speed on the way, and injecting water → rinsing → dehydration → water injection → rinsing. May be executed. At this time, since the washing tub 5 is upright, even if the washing tub 5 is rotated at high speed, generation of vibration and noise is suppressed low.

That is, even when the clothes are biased to one side of the washing tank 5 at the end of the washing stroke, the rinsing performed by standing the washing tank 5 upright is eliminated. Vibration or noise can be reduced.

In addition, before starting to inject water for the rinsing stroke, in the state of opening the drain valve, the rotary motor 11 is rotated (for example, rotates at a rotation speed around 800 rpm) so as to "intermediate dewatering (washing tank ( 5) may be performed, and water injection, rinsing (turning of the pulsator 4), and drainage may be performed simultaneously.

(S9: Dehydration)

Dewatering is performed by rotating the rotating motor 11 (washing tank 5) at high speed in the state in which the washing tank 5 stood upright. At this time, since the one-sided load (force acting obliquely with respect to the rotating shaft) of the gravity component does not act on the washing tank 5, the rotation is stabilized. Therefore, even when the clothes in the washing tub 5 are biased, severe vibration and noise are not generated during high-speed rotation, and the washing tub 5 (water tank 2) does not collide with the housing 1.

(S10: tilt)

At the point where dehydration is finished, the tilt lock mechanism is opened, and the tilt of the washing tank 5 is started and tilted. That is, the tilt motor 21 is driven again, for example, the inclination angle detector detects that the inclination angle θ becomes 30 ° (θ = 30 °) or the position of the inclination angle 30 ° Since the inclination angle detector (corresponding to the upper limit sensor) installed in the operation is stopped, the tilt motor 21 is stopped and the tilt lock mechanism is operated (locked).

(S11: dry)

Then, the heater 17 is energized (0N), the drying fan 15 is started (0N), and warm air is supplied to the water tank 2 via the ventilation duct 16. At this time, the washing tank 5 is in an inclined state, and the "stirring rotation" by the inversion of the pulsator 4 is performed, an asymmetrical force acts on clothing, and the washing tank 5 stands upright. Stirring of clothing is accelerated | stimulated than when it is in a state, drying can be performed efficiently, and drying stain can be reduced. However, when the quantity of clothes put in is large, you may dry with the washing tank 5 standing up (refer FIG. 8). In addition, "stirring rotation" refers to the operation of inverting the pulsator 4 largely and replacing clothes.

In addition, the rotary motor 11 and the drying fan 15 may be started in parallel with the tilting operation.

7, 8, the opening of the water supply valve 14 during the drying stroke slightly feeds the washing tank 5 (sprays directly to the clothing) to prevent static electricity, or to change the water supply direction by a switching valve (not shown). In other words, when the warm air after contributing to the drying of the clothes is returned to the circulating duct, water is sprayed toward the warm air in the duct. That is, it is for promoting the dew condensation of the water (containing in the warm air) evaporated from the clothes. However, the water supply in the drying stroke may be stopped.

(S12: tilt)

At the end of the drying stroke, the tilt lock mechanism is opened, the washing tank 5 is tilted again, and the tilt angle is set to 20 °. In addition, immediately before the end of the drying stroke, the washing tank 5 may be started in parallel with the drying.

(S13 out)

Then, at the time when tilting ends (the tilt angle reaches 20 °), the lid lock is released under the condition of the operation (lock) of the tilt lock mechanism and the stop of the rotary motor 11. Then, the user can open the outer lid 9 (the inner lid 8 also opens in conjunction), and can easily take out the clothes from the washing tub 5. At this time, since the washing tank 5 is inclined, the hand is easily touched in the washing tank 5, and the upper opening of the washing tank 5 faces the user's eyeline direction, so that the washing tank 5 is inclined to the bottom of the washing tank 5. Easy to peek

In addition, when the quantity of clothes is large, a user may be able to designate a default position and may make the washing tank 5 stand upright when taking out clothes.

(S14: tilt)

Then, when the clothing is taken out and the cover 9 (and the cover 8) is closed, the washing tank 5 (same as the water tank 2) is tilted and upright, and in this upright state, the cover lock is Open (opens free).

(S15: End)

Then, the power switch is automatically turned off (0FF), and the series of strokes are all finished.

At this time, since the inclined table 20 is supported in a wide range of the horizontal table 19, the own weight of the water tank 2 etc. does not concentrate and act on the tilting point 20a. Therefore, the tilt point 20a is opened from the load for a long time, and the durability is improved.

In addition, the user may be able to designate a default position and end the washing tank 5 in an inclined state.

(Washing performance)

9 is a correlation diagram qualitatively explaining the relationship between the inclination angle of the washing tub and the washing performance in the washing machine shown in FIG. 1. The vertical axis | shaft makes the contamination removal degree in the case of standing up and washing 100%, and the ratio of the contamination removal degree in the case of inclined washing | cleaning to this is made into "washing performance." In other words, the larger the value of the cleaning performance, the more the "pollution is removed."

In the case of washing upright, the deviation of the degree of contamination removal is 100%, and the ratio of the deviation of the degree of contamination removal is referred to as "cleaning stain" in the case of tilting and washing. In other words, the smaller the value of the cleaning stain, the more "the contamination falls uniformly."

In Fig. 9, when the inclination angle is 15 ° to 20 °, both the cleaning performance and the cleaning spots show good values. In addition, the curve shown in FIG. 9 changes also with the quantity of clothing (similar to the load quantity), the shape and size of a washing tank, etc. which are put into a washing tank.

(Tilt effect)

FIG. 10: is a schematic diagram explaining the force acting on the washing tub in the washing machine shown in FIG.

In FIG. 10, when stopped, the surface (water surface) of the washing water is filled horizontally, but since the washing tank 5 is inclined, the washing tank 5 is inclined with respect to the rotation axis of the washing tank 5. And when the washing tank 5 is rotated in the state in which the housing 1 was inclined at the inclination angle (theta) toward the front surface side of the housing 1, the quality (mass) of the mass [m] in the inner peripheral surface of the washing tank 5 ( Vi), gravity [m · g (g is gravity acceleration)] in the vertical direction and centrifugal force [F] act in the radial direction of the washing tank 5, respectively. At this time, the gravity [m · g] is a force in the direction of pressing the inner circumferential surface at the position on the front side (represented as [+ m · g · sinθ] in the figure) and a direction falling from the inner circumferential surface at the position on the rear side. Since it acts as (-m · g · sinθ] in the drawing), the rotating surface (water surface) downward direction component becomes the rotating surface (water surface) upward direction component on the front surface side.

Accordingly, when the washing tank 5 is upright and rotates, the water surface forms a rotationally symmetrical plane about the rotation axis, while when the washing tank 5 is inclined and the water surface forms an asymmetrical surface with respect to the rotation axis. As a result, the forces acting on the washing water and the clothes in the washing tank 5 become asymmetrical with respect to the rotation axis, and the water flow and the movement of the clothes become complicated as compared to when the washing tank 5 is in an upright state, and the washing power increases. In addition, cleaning stains are also reduced (see FIG. 9).

(Determination of tilt angle)

As mentioned above, although the inclination angle in a washing | cleaning stroke is 30 degrees, the case of putting in or taking out clothes, and the inclination angle in a drying stroke is illustrated as an example of 20 degrees, this invention is not limited to this, In a washing | cleaning stroke, The predetermined tilt angle can be determined according to the amount of clothing (corresponding to the load amount) within a range of 10 ° to 45 °. Further, the inclination angle can be selected within the range of 0 ° to 30 ° at the time of feeding or taking out the clothes and in the drying stroke.

That is, as described above, since the inclination angle for maximizing the cleaning performance also varies depending on the shape and size of the washing tub and the amount of clothes to be put in, the determination of the inclination angle (cleaning stroke) in consideration of such a variation factor is made. desirable.

In addition, it is preferable that the inclination angle (ejection stroke) is determined in consideration of the elongation of the user, the size of the housing, and the like. Moreover, you may make it possible for each user to set the inclination angle (ejection stroke) which is easy to use, respectively. At this time, the opening formed in the top cover 10, that is, the outer cover 9, in order to respond to the request to put or remove clothes in the state where the washing tank 5 is upright, the washing tank 5 is upright. Since it is necessary to make it the size which can take out a garment at the time, for example, when it projects to the horizontal plane, the upper opening part (equivalent to the lid 8) of the washing tub 5 at the time of standing up is covered with the outer cover 9 ) To be included (covered). That is, the outer cover 9 is long toward the rear side.

In addition, in the case where the inclination angles before and after the tilt are equal, for example, when any stroke is executed at the same inclination angle, for example, when the clothes are fed and shifted to the washing stroke, Surprisingly, when shifting from the drying stroke to the removal of clothes, of course, disappears. That is, the time required for a series of driving courses can be shortened, and the load on the tilting mechanism can be reduced, so that the time required for tilting (change of the tilting angle) becomes unnecessary.

Incidentally, the inclination angle in the cleaning stroke or the drying stroke is not limited to one, but is changed stepwise (stepwise) by selecting one or two or more inclination angles within the range of 10 ° to 45 ° or 0 ° to 30 °. It is also possible to continuously vary the inclination angle within the range, that is, between the minimum inclination angle (including uprights) and the maximum inclination angle inclination once or twice or more times (referred to as "sway" in the present invention). May be called).

At this time, new complex water flow and agitation of clothes are generated in the washing, and the washing performance is improved, and new clothes are agitated in the drying, so that warm air can be included in the bundle of clothes, and the drying speed is improved. do.

(Upright washing method)

Although already demonstrated, the upright washing | cleaning method is put together below (refer FIG. 8).

The upright washing method is to prevent the washing water from overflowing or becoming unwashable when the amount of clothes put is large. That is, when the washing tank 5 stands up, the quantity of wash water which can be supplied to it (it does not overflow during washing) becomes larger than when the washing tank 5 is inclined. Therefore, by enabling the upright washing method, a large amount of clothes can be washed without increasing the washing tank 5 (same as the housing 1). Moreover, although it is dried in the upright washing tank 5, you may incline to wash the washing tank 5 and dry it. At this time, the above-mentioned drying promotion effect is achieved.

(Modification example 1 of a washing machine)

11 and 12 are side cross-sectional views schematically showing that the position of the tilting point of the washing machine shown in FIG. 1 is changed, and description of some members is omitted.

In FIG. 11A, the washing machine 200 is inclined to a range close to the top surface of the front surface of the washing machine 100 shown in FIG. 1. That is, the tilting point 20a is located at a position near the front surface of the horizontal stage 19, and the rack 23 pushes up the tilting table 20 at a position near the rear side (hereinafter referred to as a "tilting action point") 23a. have. For this reason, since the front face of the opening part of the washing tub 5 is close to the front face of the housing 1 by the distance "D1" by making the lower part of the front face of the water tank 2 into a rotation center, as mentioned above, a user is easy to get in and out of clothing. In addition, the clothing is not dropped in the gap between the water tank 2 and the housing 1. At this time, since the upper range of the front surface of the housing 1 is inclined so as to be substantially parallel to the inclined washing tank 5 (same as the water tank 2), the user should be closer to the washing tank 5 further. It becomes possible.

By the way, the time chart shown to FIG. 7, 8 shows the case where tilting (inclination from upright) starts after pouring water into the washing tank 5, and starts tilting (from inclination state to upright state) after draining. However, the present invention is not limited to this, but water may be injected after the washing tank 5 is tilted (inclined from upright), and draining may be started after the tilting (from the tilted state toward the upright state) is finished. .

In this way, when the water injection is delayed, the washing tank 5 before it becomes heavy is lifted, and the load of the tilt motor 21 becomes lighter, so that the tilt time is shortened with the energy saving effect. In addition, when the drainage is slowed down, the heavy washing tank 5 is lifted down (falls down while supporting the load), and the load of the tilt motor 21 becomes lighter, so that the tilt time is increased with the energy saving effect. Shorten.

(Modification 2 of Washing Machine)

In FIG. 11B, the washing machine 300 provides a rail 19a parallel to the front and rear directions of the housing 1 near the front surface of the horizontal stage 19, and the tilting point of the tilting platform 20 ( 20a) slides freely along the rail 19a. That is, when tilting, the upper front side of the washing tub 5 descends in parallel with the front surface of the housing 1 (moving from position "2c" to position "2e").

Therefore, since the front surface of the housing 1 can be flattened by such a configuration, when the user cleans the surroundings, works outside, or passes through the vicinity, the washing machine 300 is disturbed. There is no In addition, regarding the timing of water injection, drainage, and tilting, the washing machine 100 is used.

(Modification 3 of Washing Machine)

In FIG. 12A, the washing machine 400 is a case where the position “20b” near the rear surface of the housing 1, that is, the lower rear surface of the washing tank 5 is a tilting point. By adopting such a configuration, the height of the front surface side of the upper opening of the washing tub 5 can be lowered larger than when the tilting point is disposed at other positions, so that a child, a short person, or a car (Iii) A person sitting on a chair, for example, makes it easier to add clothes or take out clothes.

In addition, in the washing machine 400, the timing of water injection and drainage is not limited, but it is lifted up after drainage (beveled from the inclined state to the upright state), and when this is lifted up after pouring water into the washing tank 5 (upright) Tilt from the state to the inclined state), the load of the tilt motor 21 is light, and the tilt time is shortened with the energy saving effect.

(Modification 4 of washing machine)

In FIG. 12B, the washing machine 500 forms the horizontal stand 19 and the tilting stand 20 as the frame (not shown), and the water tank 2 penetrates the inside of the frame. have. The tilt table 20 is a horizontal stand using the center position "20c" (corresponding to the center of the front and rear directions of the tank 2 (same as the washing tank 5) and the vertical direction) of the tank 2 as the tilting point. (19) is installed freely tilted.

By taking such a configuration, the front side of the water tank 2 falls (forwards) toward the front, the lower half falls down (retreats) toward the rear, and the front side of the upper edge of the water tank 2 is relatively small. Descending while drawing an arc. Therefore, if the upper part of the front surface of the housing 1 is inclined only in a relatively narrow range, the front surface side of the upper edge of the water tank 2 can be lowered largely (by distance "E4") at a relatively small tilt angle. . That is, since the clearance gap between the front surface of the housing 1 and the water tank 2 can be narrowed at the time of standing up, the housing 1 becomes compact.

In addition, the installation of the tilt table 20 may be abbreviate | omitted and the water tank 2 may be directly drained.

In addition, in the washing machine 500, the timing of water injection, drainage, and tilting is not limited. However, when tilting the washing tank 5 (particularly, tilting it with water injected therein), the tilting force of the washing tank 5 acts further on the washing tank 5, so that the washing tank 5 is inclined. It is necessary to connect the rack 23, and the tilting platform 20 can be raised and lowered by the rack 23 freely. Alternatively, a worm mechanism may be employed in place of the rack / pinion mechanism. At this time, the shaft held by the tilting point 20c may be directly rotated.

(Other washing machines)

As is clear from the above description, the position of the tilt mechanism and the tilt point is not limited in the present invention, and variations other than the above can be employed. For example, the tilting point 20c of the washing machine 400 may be moved to the upper end of the water tank 2 (not shown). At this time, the front surface side of the upper end of the water tank 2 descends by tilting, with almost no retreat. For example, the tilting point 20c of the washing machine 500 may be moved to the upper end of the water tank 2 (not shown). At this time, the front side of the upper end of the water tank 2 is slightly retracted by a small radius by tilting, but can be lowered by a desired amount.

In addition, if the tilting point is moved to the upper end of the water tank 2 in this way, the water supply path 12 can be made cheap and simple. That is, even in the water supply path 12 which lacks flexibility and elasticity, the water supply path 12 can communicate with the water tank 2 by a well-known swivel joint.

Since the present invention has the above-described configuration, the washing performance is good, the water is quietly dehydrated, and the ejection of clothes can be easily used, and thus it can be widely used as a washing machine for various homes and businesses.
