Description

washing machine

Technical field

The invention relates to a washing machine.

Background technique

A washing method using magnesium is known. If you put magnesium into the bucket of the washing machine, the magnesium (Mg) will react _{chemically with the water (H 2} O) in the bucket to produce magnesium hydroxide (Mg(OH) ₂ ) and hydrogen (H ₂ ). The water in the bucket will be alkaline ionized water ^- is modified to contain a magnesium ion (Mg ²⁺⁾ and hydroxide ions (OH). Alkaline ionized water has the function of decomposing fats and oils in the same way as detergent, so it can use alkaline ionized water to remove dirt from the laundry in the bucket. In addition, alkaline ionized water has a sterilization effect, so negative ion water can be used to sterilize the washing in the bucket and the bucket itself.

The alkaline ionized water generator described in Patent Document 1 described below has a main body made of a sponge and magnesium particles contained in the main body. The alkaline ionized water generator is put into the bucket of the washing machine together with the laundry. When water is injected into the bucket, magnesium is eluted from the magnesium particles in the alkaline ionized water generator into the water in the bucket, so the magnesium reacts chemically with the water in the bucket to produce alkaline ionized water.

By spraying a large amount of alkaline ionized water onto the laundry, the laundry can be effectively washed. On the other hand, the alkaline ionized water generator described in Patent Document 1 is suspended in the water in the bucket. In this case, all the magnesium particles in the alkaline ionized water generator may not be immersed in the water in the bucket. In addition, the alkaline ionized water generator described in Patent Document 1 has a small storage capacity of magnesium particles. Therefore, in the case of the alkaline ionized water generating tool described in Patent Document 1, there is a limit to promote the chemical reaction of magnesium and water to produce a large amount of alkaline ionized water.

Invention effect

According to the present invention, in the washing machine, the accommodating portion accommodating the magnesium particles in the accommodating chamber is mounted on the rotating wing arranged in the washing tub at a position immersed in the washing water. Thereby, the accommodating part is arrange|positioned at a position lower than the water surface of the washing water in a washing tub. Therefore, the washing water in the washing tub actively flows into the storage chamber by flowing down from the inflow port of the ceiling wall arranged on the upper side of the storage chamber in the storage section. In this way, the chemical reaction between the magnesium particles and the washing water is promoted in the storage chamber to efficiently produce alkaline ionized water. The alkaline ionized water generated in this way moves to the radially outer side in the storage chamber by the centrifugal force caused by the rotation of the rotor blade, and actively flows out from the outflow port of the outer wall. Then, in this way, the washing water in the washing tub is circulated in such a way that it repeatedly enters and exits the chamber through the inflow port and the outflow port, thereby generating a large amount of alkaline ionized water in the washing tub, so it can effectively pass through a large amount of alkaline ionized water Wash the laundry in the washing tub locally. Therefore, it is possible to improve the washing performance of the laundry in the washing tub by the magnesium particles.

In addition, according to the present invention, the bottom wall of the accommodating portion is provided with a first region and a second region that is inclined upward as it moves away from the first region to the radially outer side from the lower side toward the inner surface of the accommodating chamber. As a result, first, the washing water flowing into the storage chamber from the inflow port of the ceiling wall is stored in the vicinity of the first area, and therefore the chemical reaction between the magnesium particles and the washing water is promoted in the first area to efficiently generate alkaline ionized water. Then, when the rotor blade rotates, the centrifugal force causes the magnesium particles in the storage chamber to move radially outward and are widely distributed on the second area. Therefore, the contact area of each magnesium particle with the washing water is enlarged. As a result, the chemical reaction between the magnesium particles and the washing water is further promoted in the storage chamber to more efficiently generate alkaline ionized water and supply it to the washing tub. Therefore, it is possible to further improve the washing performance of the laundry in the washing tub by the magnesium particles.

In addition, according to the present invention, the inflow port of the washing water in the accommodating portion is formed on the bottom surface of the concave portion recessed on the lower side of the upper surface portion of the top wall, so the washing water on the top wall is efficiently guided to the inflow port by the concave portion . As a result, the chemical reaction between the washing water flowing into the storage chamber from the inflow port and the magnesium particles is promoted to efficiently generate alkaline ionized water and supply it into the washing tub. Therefore, it is possible to further improve the washing performance of the laundry in the washing tub by the magnesium particles.

In addition, according to the present invention, the top wall is provided with an inclined surface that slopes downward from the upper side toward the storage chamber as it approaches the center of rotation of the rotor. Therefore, the washing water adhering to the top wall in the storage chamber is absorbed by the The inclined surface portion is guided to fall, and thereby it receives the centrifugal force caused by the rotation of the rotating wing and actively moves to the outflow port. Therefore, the washing water can be promoted to flow out of the outflow port from the storage chamber, that is, the supply of alkaline ionized water from the storage chamber into the washing tub can be promoted. Therefore, it is possible to further improve the washing performance of the laundry in the washing tub by the magnesium particles.

In addition, according to the present invention, the accommodating portion is an annular body extending in the circumferential direction around the rotation center, and therefore the outer side wall thereof is also formed in an annular shape. As a result, the outflow ports formed in the outer wall are arranged to be distributed over the entire circumferential direction on the annular outer wall. Therefore, the washing water generated in the storage chamber efficiently flows out from the outflow ports and is supplied to the washing tub Inside. Therefore, it is possible to further improve the washing performance of the laundry in the washing tub by the magnesium particles.

In addition, the accommodating part can be attached to and detached from the rotating wing. Then, the accommodating part includes a replenishing port for replenishing magnesium particles into the accommodating chamber and an opening and closing part for opening and closing the replenishing port. Therefore, the user opens the opening and closing part after detaching the accommodating part from the rotary wing, and moves from the replenishing port to the accommodating chamber. Replenishing the magnesium particles, and then closing the opening and closing part and attaching the accommodating part to the rotating wing, the accommodating part can be maintained.

The size in the vertical direction Z of the storage chamber 10A partitioned from the lower side Z2 by such a bottom wall 33 is constant in the first zone 33B, but becomes narrower on the upper side Z1 in the third zone 33D, and in the second zone 33C The upper side gradually narrows toward the upper side Z1 as it approaches the radially outer side R2. Therefore, the longitudinal section of the storage chamber 10A when it is cut at one location on the circumference has a substantially trapezoidal shape that narrows toward the upper side Z1 as it approaches the radially outer side R2.

The accommodating portion 10 as described above is fitted into the groove 5A of the upper surface portion of the rotor blade 5. In the accommodating portion 10 in this state, the upper surface portion of the top wall 31 and the upper surface portions of the central portion 5B and each raised portion 5C of the rotor blade 5 are arranged at substantially the same height position. Each raised portion 5C is arranged at a position shifted from the group G of the outflow port 32A in the outer side wall 32 of the housing portion 10 in the circumferential direction P. Therefore, the outflow port 32A of each group G is in a state which is open to the radially outer side R2 without being blocked by the bulge 5C from the radially outer side R2. The accommodating part 10 in the state of being fitted into the groove 5A can be attached to and detached from the rotary wing 5 by a well-known locking structure such as screw fixing or snapping.

A plurality of magnesium particles M are stored in the storage chamber 10A of the storage section 10. The magnesium particles M are particles made of magnesium, and the particle size of the magnesium particles M in a new product is set to a size of about several mm that the magnesium particles M cannot pass through the inflow port 31G and the outflow port 32A. The user can detach the accommodating portion 10 from the rotary wing 5 as needed, and then open the opening and closing portion 35 of the accommodating portion 10 to replenish the magnesium particles M from the replenishing port 31A to the accommodating chamber 10A. When the user closes the opening and closing portion 35, the first engaging portion 35C of the opening and closing portion 35 engages with any of the second engaging portions 32B of the outer side wall 32, so the opening and closing portion 35 is positioned so as not to be arbitrarily from the closed position To open. It should be noted that, in this embodiment, the first engaging portion 35C is a claw, and the second engaging portion 32B is a hole. However, the opposite is also possible, and the first engaging portion 35C and the second engaging portion 32B are also Both can be claws.

The washing machine 1 further includes, for example, a control unit 40 (refer to FIG. 1) composed of a microcomputer and built in the cabinet 2. The control unit 40 includes memories such as CPU, ROM, and RAM, and a timer for timekeeping. The motor 6, the transmission mechanism 7, the display operation unit 17, the water supply valve (not shown), and the drain valve (not shown) are electrically connected to the control unit 40, respectively. The control unit 40 controls the motor 6 to rotate at a desired rotation speed by controlling the duty ratio of the voltage applied to the motor 6. The control unit 40 controls the transmission mechanism 7 to switch the transmission destination of the driving force of the motor 6 to one or both of the support shaft 24 and the rotation shaft 25. When the user operates the display operation unit 17 to select operating conditions and the like, the control unit 40 receives the selection. The control unit 40 controls the display of the display operation unit 17. The control unit 40 controls the opening and closing of the above-mentioned water supply valve and drain valve.

The control unit 40 executes the washing operation by controlling the operation of the motor 6, the transmission mechanism 7, the water supply valve, and the drain valve. As an example, the washing operation has: a dipping operation, in which the laundry L is immersed in the washing water in the washing tub 4 for a predetermined time; a formal washing operation, in which the laundry L is officially washed after the immersion operation; and a rinsing operation, in the formal washing Rinse the laundry L after the operation; and spin-dry the laundry L after the rinsing operation.

1, in the dipping operation, first, the control unit 40 opens the water supply valve and supplies water to the washing tub 4. As a result, washing water can be stored in the washing tub 4. When the water level in the washing tub 4 rises to a soaking water level higher than the upper end of the laundry L in the washing tub 4, the control unit 40 stops the water supply by closing the water supply valve. At this time, the rotating blade 5 and the accommodating portion 10 arranged at the deepest part on the bottom wall 4B side in the washing tub 4 are immersed in the washing water in the washing tub 4.

The washing water in the washing tub 4 drops from the inflow port 31G of the ceiling wall 31 and flows into the storage chamber 10A of the storage section 10 (refer to the black arrow W1 in FIG. 6). In the storage chamber 10A, the washing water chemically reacts with the magnesium component dissolved in the washing water from the magnesium particles M. Regarding the details of the chemical reaction between the washing water and magnesium, as described above, the chemical reaction increases the pH of the washing water in the storage chamber 10A, thereby being modified into alkaline ionized water. During the dipping operation, the control unit 40 periodically rotates the rotor blade 5, for example. Then, the accommodating portion 10 also integrally rotates the rotor blade 5, so the alkaline ionized water in the accommodating chamber 10A flows radially outward R2 by centrifugal force, and flows out of the outlet 32A of the outer wall 32 into the washing tub 4 (see FIG. 6 Black arrow W2). In this way, the washing water passes through the inflow port 31G and the outflow port 32A to communicate with the storage chamber 10A in the washing tub 4, whereby most of the washing water in the washing tub 4 becomes alkaline ionized water. Therefore, in the immersion washing operation, the laundry L in the washing tub 4 is immersed in the alkaline ionized water of the washing water in which the magnesium particles M are dissolved in the accommodating portion 10.

As described above, the washing water is alkaline ionized water. Like detergents, the alkaline ionized water has a function of decomposing fats and oils, specifically acidic sebum dirt. Therefore, the laundry L in the washing tub 4 is immersed in the alkaline ionized water stored in the washing tub 4 to remove dirt. When the predetermined dipping time has elapsed after the water supply is stopped, the control unit 40 ends the dipping operation.

Next, the control unit 40 starts the main washing operation and rotates the rotor blade 5. The rotation speed of the rotor blade 5 at this time is preferably higher than the rotation speed of the rotor blade 5 during the immersion operation. As a result, the washing water in the space S on the bottom wall 4B side in the washing tub 4 is pushed to the radially outer side R2 by the back blade 5D of the rotating blade 5 rotating at a high speed, and is sent into the inlet 27A of each circulation channel 27. The washing water flowing in each circulation channel 27 to the upper side Z1 passes through the filter (not shown) of the filtration unit 9 and flows out from the outlet 27B of the circulation channel 27 to the radially inner side R1 (refer to the thick dotted arrow W3 in FIG. 1) . The filter captures foreign substances such as thread ends from the washing water passing through the filter, and stores them in the filter unit 9. The washing water returning from the outlet 27B to the washing tub 4 sprays the washing L in the washing tub 4 from the upper side Z1, then flows into the space S, and circulates again by spraying the washing L through the circulation flow path 27.

In the actual washing operation, the washing water circulates in accordance with the rotation of the rotary blade 5 in this manner, and the washing L is sprayed with alkaline ionized water. Furthermore, since the laundry L is stirred by the raised portion 5C of the rotating rotor blade 5, the dirt on the laundry L can be mechanically removed. It should be noted that, at the start of the washing operation, etc., the detergent may be automatically injected into the washing tub 4, or the detergent may be injected by manual operation of the user. The washing water in this case contains detergent components, and during the main washing operation, the dirt on the laundry L is chemically decomposed by the detergent components. It should be noted that the alkaline component in the alkaline ionized water functions the same as the detergent, so even if the amount of detergent used is small or zero, the alkaline component can be used to supplement the detergent or replace the detergent. High cleaning effect. By suppressing the amount of detergent used in this way, the load on the environment caused by the detergent can be reduced. When a predetermined washing time has elapsed from the start of the circulation of washing water accompanying the rotation of the rotor blade 5, the control unit 40 stops the rotor blade 5 and opens the drain valve to drain water from the washing tub 4, thereby ending the main cleaning operation.

Then, the control unit 40 starts the rinsing operation. Specifically, the control unit 40 opens a water supply valve (not shown) to supply water to the washing tub 4, and stores the washing water in the washing tub 4 until the predetermined rinsing water level. Then, the control unit 40 rotates the rotary wing 5. In the rinsing operation, as in the main washing operation, washing water circulates along with the rotation of the rotor blade 5, and alkaline ionized water is sprayed to the laundry L, the water tub 3 of the washing tub 4, and the washing tub 4. As a result, the dirt remaining on the laundry L is removed by the alkaline ionized water, and the laundry L, the water tub 3, and the washing tub 4 are sterilized by the negative ions contained in the alkaline ionized water and the like. When a predetermined rinsing time elapses from the start of the circulation of the washing water accompanying the rotation of the rotor blade 5, the control unit 40 stops the rotor blade 5 and opens the drain valve to drain water from the washing tub 4, thereby ending the rinsing operation. The rinsing operation can also be carried out multiple times. As described above, in the actual washing operation, the amount of detergent used can be suppressed by the alkaline ionized water, so the amount of water required for the subsequent rinsing operation can be suppressed, and the laundry L can be rinsed in a short time. As a result, water saving, energy saving, and time reduction can be achieved.

Next, the control unit 40 starts the dehydration operation. Specifically, the control unit 40 spins and spins the washing tub 4 in a state where the drain valve is opened. The rotation speed of the washing tub 4 during spin-drying increases stepwise, and finally reaches the maximum rotation speed of, for example, 800 rpm, and then the voltage application to the motor 6 is stopped, whereby the washing tub 4 performs inertial rotation. Utilizing the centrifugal force caused by the dehydration rotation of the washing tub 4, the laundry L in the washing tub 4 is dehydrated. The water seeping out from the laundry L by dehydration is discharged from the drain 21 to the outside of the machine. When the inertial rotation of the washing tub 4 stops, the control unit 40 ends the dehydration operation. The dehydration operation may be implemented as the final dehydration operation at the end of the washing operation, or may be implemented as an intermediate dehydration operation immediately after the main washing operation or the like is completed.

As described above, in the washing machine 1, the accommodating portion 10 accommodating the magnesium particles M in the accommodating chamber 10A is attached to the rotary wing 5 arranged in the washing tub 4 at a position immersed in washing water. As a result, the accommodating portion 10 is arranged at a position lower than the water surface of the washing water in the washing tub 4. Therefore, as shown in FIG. 6, the washing water in the washing tub 4 flows into the storage chamber 10A by flowing down from the inlet 31G of the ceiling wall 31 arranged on the upper side Z1 of the storage chamber 10A in the storage section 10. Thereby, in the storage chamber 10A, the chemical reaction between the magnesium particles M and the washing water is promoted to efficiently produce alkaline ionized water. The alkaline ionized water generated in this way moves to the radially outer side R2 in the storage chamber 10A by the centrifugal force caused by the rotation of the rotor blade 5, and actively flows out from the outflow port 32A of the outer wall 32. Then, the washing water in the washing tub 4 is circulated in such a manner that the washing water in the washing tub 4 repeatedly enters and exits the storage chamber 10A through the inflow port 31G and the outflow port 32A. As a result, a large amount of alkaline ionized water is generated in the washing tub 4. The alkaline ionized water effectively washes the laundry L in the washing tub 4. Therefore, the washing performance of the laundry L in the washing tub 4 can be improved by the magnesium particles M. In particular, since a large amount of magnesium particles M can be accommodated in a dedicated space such as the accommodating portion 10, a large amount of alkaline ionized water can be generated to improve the washing performance.

In addition, in the bottom wall 33 of the accommodating portion 10, an inner surface portion 33A facing the accommodating chamber 10A is provided with a first area 33B and a second area 33C that is inclined to the upper side Z1 as it moves away from the first area 33B to the radially outer side R2. . Thus, first, the magnesium particles M and the washing water flowing into the storage chamber 10A from the inflow port 31G of the top wall 31 are stored in the vicinity of the first region 33B, and therefore the chemical reaction between the magnesium particles M and the washing water is promoted in the first region 33B. And efficiently generate alkaline ionized water. Then, when the rotor blade 5 rotates, the centrifugal force causes the magnesium particles M in the storage chamber 10A to move to the radially outer side R2 and are widely distributed on the second area 33C. Therefore, the contact area of each magnesium particle M with the washing water is expand. As a result, in the storage chamber 10A, in all operations except the dehydration operation, the chemical reaction between the magnesium particles M and the washing water is always promoted to efficiently produce alkaline ionized water, and the alkaline ionized water is supplied to the washing tub 4. Therefore, the washing performance of the laundry L in the washing tub 4 can be further improved by the magnesium particles M.

In addition, the washing water inflow port 31G in the accommodating portion 10 is formed in the bottom surface 31D of the concave portion 31C recessed in the upper surface portion 31B of the top wall 31 to the lower side Z2, so the washing water on the top wall 31 is efficiently used by the concave portion 31C. The ground is guided to the inflow port 31G. In addition, the concave portion 31C is provided with an outer inclined surface 31E and an inner inclined surface 31F inclined from the bottom surface 31D to the upper side Z1, so the wash water on the top wall 31 is efficiently guided to the inflow port 31G by these inclined surfaces. Thereby, the chemical reaction of the washing water flowing into the storage chamber 10A from the inflow port 31G and the magnesium particles M is promoted to efficiently generate alkaline ionized water and supply it into the washing tub 4. Therefore, the washing performance of the laundry L in the washing tub 4 can be further improved by the magnesium particles M.

In addition, the top wall 31 is provided with a slope portion 31H that faces the storage chamber 10A from the upper side Z1 and is inclined to the lower side Z2 as it approaches the rotation axis J. Therefore, the washing water adhering to the top wall 31 in the storage chamber 10A is covered by The inclined surface portion 31H is guided and dropped, thereby receiving the centrifugal force caused by the rotation of the rotor blade 5 and actively moving toward the outflow port 32A. Therefore, the flow of washing water from the storage chamber 10A to the outside of the outflow port 32A can be promoted, that is, the supply of alkaline ionized water from the storage chamber 10A into the washing tub 4 can be promoted. Therefore, the washing performance of the laundry L in the washing tub 4 can be further improved by the magnesium particles M.

In addition, the accommodating portion 10 is an annular body extending in the circumferential direction P around the rotation axis J, and therefore the outer side wall 32 thereof is also formed in an annular shape. As a result, the outflow ports 32A formed in the outer side wall 32 are arranged to be distributed over the entire area of the circumferential direction P on the annular outer side wall 32. Therefore, the washing water generated in the storage chamber 10A efficiently flows out from each outflow port 32A. , And is supplied to the washing tub 4. Therefore, the washing performance of the laundry L in the washing tub 4 can be further improved by the magnesium particles M.

Then, the accommodating portion 10 can be attached to and detached from the rotary wing 5. Then, the accommodating portion 10 includes a replenishing port 31A for replenishing the magnesium granules M into the accommodating chamber 10A and an opening and closing portion 35 that opens and closes the replenishing port 31A. Therefore, the user opens and closes the accommodating portion 10 after detaching the accommodating portion 10 from the rotating wing The portion 35 replenishes the magnesium granules M from the replenishment port 31A to the storage chamber 10A, and then the opening and closing portion 35 is closed and the storage portion 10 is attached from the rotary wing 5, whereby the storage portion 10 can be maintained.

The magnesium particles M have, for example, a silver surface when they are new, but when they are repeatedly contacted with washing water due to use, an oxide film is formed on the surface and deteriorated, for example, it becomes black. The deteriorated magnesium particles M are difficult to chemically react with the washing water. Therefore, as maintenance other than replenishing the magnesium particles M from the replenishing port 31A to the storage chamber 10A as described above, the user may manually put a predetermined detergent into the washing tub 4 in which the washing water is stored, for example. Examples of the cleaning agent include citric acid tablets and liquids.

Thus, in the washing tub 4, the detergent is dissolved in the washing water to produce a citric acid aqueous solution, which flows into the storage chamber 10A from the inflow port 31G and the outflow port 32A, and the magnesium particles M in the storage chamber 10A are immersed in the citric acid aqueous solution. Then, the magnesium particles M are regenerated by removing the oxide film from the surface. It should be noted that, as described above, the user may detach the storage section 10 from the rotor blade 5 and immerse it in the citric acid aqueous solution stored in a bucket or the like to maintain the magnesium particles M in the storage section 10. In addition, in order for the user to visually grasp the state of the magnesium particles M in the storage chamber 10A, the top wall 31, the opening/closing portion 35, and the like of the storage portion 10 may be transparent or translucent.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope described in the technical solution.

For example, the accommodating chamber 10A for accommodating magnesium particles in the accommodating portion 10 may be an annular space extending in the circumferential direction P, or may be partitioned into a plurality of spaces arranged in the circumferential direction P. When the storage chamber 10A is partitioned into a plurality of spaces, a plurality of opening and closing portions 35 for replenishing the magnesium particles M to the space are provided in each space. It should be noted that the opening and closing portion 35 may be provided in an area other than the top wall 31 in the accommodating portion 10, or may be opened and closed by sliding instead of rotating.

In addition, the washing machine 1 is a vertical washing machine in the above-mentioned embodiment, but it may be a drum washing machine in which the rotation axis J of the washing tub 4 extends horizontally in the front-rear direction Y. Moreover, the washing machine 1 may be an integrated washer-dryer with a drying function, or may be a double-tub washing machine.
