Description

  The present invention relates to a washing / drying machine, and more particularly to a washing / drying machine provided with means for spraying a high-concentration detergent solution onto clothes.

At the beginning of the washing process, a detergent is dissolved in a small amount of water to produce a high-concentration detergent solution (detergent concentration is preferably 5 to 10 times). Washing and drying machines that perform are known.
Since the washing process is performed after the high-concentration detergent solution acts on the dirt and the dirt is easily removed from the clothes, there is an effect of obtaining a high detergency. In addition, when the detergent is dissolved and then used for washing, it can be washed at a desired detergent concentration from the beginning of washing, and thus has an effect of increasing the cleaning power. Furthermore, there is an effect of preventing the detergent from remaining undissolved even in winter when the water temperature is low and the detergent is difficult to dissolve.

As a method of spraying the detergent, the vertical washing machine has a high concentration detergent solution generating means above the washing and dewatering tub, and the generated high concentration detergent solution is allowed to fall naturally, and the laundry and dewatering tub is rotated at a low speed. A method of spraying is disclosed (Patent Document 1).
In addition, in a washing machine having a circulation pump that circulates water in the outer tub, a high-concentration detergent solution generating means is provided at the bottom of the outer tub that stores the wash water, and the generated high-concentration detergent solution is drummed (washing and removing) with a circulation pump. A method of spraying into clothes and spraying it on clothing while rotating the drum at a low speed is disclosed (Patent Document 2).
Moreover, after spraying water and getting clothes wet, the method of spraying a high concentration detergent liquid from the spray nozzle of a front door upper part is disclosed (patent document 3).

Is sprayed into the washing / dehydrating tub / drum in a certain amount, so that it is difficult to spread the high-concentration detergent solution evenly over all clothing.

Moreover, in the spraying method described in Patent Document 3, the detergent liquid is misted and sprayed.
However, in order to make the detergent liquid mist, a high-concentration detergent liquid pressurized with compressed air is supplied to the spray nozzle, so an air compressor (compressor) is required and it can be applied to general household washing and drying machines. Is difficult in terms of cost and space. Moreover, although the method of spraying high concentration detergent liquid by pressurizing with a high pressure pump is also considered, this also has a problem in terms of cost.

  Therefore, an object of the present invention is to provide a washing and drying machine capable of obtaining a high detergency by spraying a high-concentration detergent solution evenly on clothes by an inexpensive method.

  In order to solve such a problem, the washing and drying machine according to claim 1 includes a housing, an outer tub that is supported in a vibration-proof manner in the housing, and stores washing water therein, and the outer tub, A rotating drum that is rotatably supported while tilting so that the rotation center axis is horizontal or opening side is high, a rotating drum in which clothing is accommodated, a motor that rotates the rotating drum, and water supply that supplies water into the rotating drum And a blower unit having a fan impeller and a driving fan motor, and a control device capable of executing the washing operation and / or the drying operation by controlling the motor, the water supply means and the fan motor. The control device controls the motor to rotate the rotating drum around the rotation center axis, and controls the fan motor to rotate the fan impeller so that the rotating drum is rotated. The volume clothing, characterized in that blowing of high concentration detergent solution is generated by supplying water to put detergent.

  According to the present invention, it is possible to provide a washing and drying machine capable of obtaining a high detergency by spraying a high-concentration detergent solution evenly on clothes by an inexpensive method.

The cooling water flows down along the wall surface of the drying duct 21, enters the outer tub 2 from the intake port 2 a, and is discharged from the drainage port 2 b to the outside through the drainage hose 19.

FIG. 4 is a top view showing an internal structure by cutting a part of the housing 1 of the washing / drying machine (drum type washing / drying machine S) according to the present embodiment.
The upper part of the drying duct 21 is connected to a filter duct 22 installed in the front-rear direction on the upper right side in the housing 1. The front surface of the filter duct 22 has an opening, and a drawer-type drying filter 8 is inserted into the opening. The dry filter 8 has a mesh filter 8a, and the air that has entered the filter duct 22 from the dry duct 21 flows into the mesh filter 8a of the dry filter 8, and lint is removed.

  The blower unit 24 includes a driving fan motor 24a, a fan impeller (not shown), and a fan case 24b. The fan case 24b has a built-in heater 25 (see FIG. 2) that heats air sent from the fan impeller.

FIG. 5 is a perspective view showing an internal structure by cutting a part of the housing 1 of the washing / drying machine (drum type washing / drying machine S) according to the present embodiment.
The discharge port of the blower unit 24 is connected to the blower duct 26. The air duct 26 is connected to a blowout port 28 provided in the outer tank cover 2d through a rubber bellows tube A (27a) and a bellows tube joint 27b. Since the blower unit 24 is provided on the upper right side in the housing 1, the air outlet 28 is provided at a position on the upper right side of the outer tub cover 2 d so as to shorten the distance to the air outlet 28 as much as possible.

The flow of wind during operation of the blower unit 24 is as shown by the arrows in FIG.
The wind discharged from the blower unit 24 passes through the blower duct 26, the bellows tube A (27a), and the bellows tube joint 27b, blows into the rotary drum 3 from the blowout port 28 (arrow 41), and hits the clothing.
This wind flows from the through hole of the rotating drum 3 to the outer tub 2 and is sucked into the drying duct 21 from the intake port 2a (see FIG. 2), and flows through the drying duct 21 from the bottom to the top (arrow 42).
Then, it enters the filter duct 22 (arrow 43), passes through the mesh filter 8a (see FIG. 4) of the drying filter 8 inserted into the filter duct 22, and the lint is removed.
Then, it circulates through the intake duct 23 so as to be sucked into the blower unit 24 (arrow 44).
The clothing is lifted to the vicinity of the air outlet 28 by the rotating drum 3 alternately rotating in the forward / reverse direction at a low speed, and the high-speed wind directly strikes the clothing evenly.

In the washing / drying machine (drum-type washing / drying machine S) according to the present embodiment, the wind speed of the air coming out from the air outlet 28 is set to about 90 m / s. For this reason, as for the ventilation unit 24, the thing of a high-speed and high pressure type is used compared with the ventilation unit currently used with the general washing-drying machine. Specifically, the discharge port pressure of the blower unit 24 is about 6000 PaG at a rotation speed of 13500 r / min [rotation / min]. This is because high-speed warm air is blown directly on the clothes to dry the wrinkles generated in the clothes.
In the case of a general washing dryer or a blower unit of a dryer, the rotational speed is 5000 r / min [rotation / min], the discharge port pressure is several hundred PaG, the wind speed is about 10 to 20 m / s, and the liquid mist There is almost no effect of wrinkling or stretching wrinkles of clothing.

<Mist conversion of highly concentrated detergent solution>
In the washing / drying machine (drum type washing / drying machine S) according to the present embodiment, a mist of a high-concentration detergent solution is generated with a high-speed wind, and this is sprayed on clothes together with the high-speed wind at the beginning of the washing operation. After the liquid is evenly distributed to the clothing and the dirt on the clothing is lifted up, the main washing is performed to increase the cleaning power in the main washing.
For this purpose, a blower unit 24 that generates high-speed wind, a blow-out port 28 that directly applies this wind to clothing, and means for supplying high-concentration detergent liquid are required.

Here, the outlet 28 will be further described with reference to FIGS. 7 and 8.
FIG. 7 is an enlarged front view of the outer tub cover 2d provided with the outlet 28 of the washing / drying machine (drum type washing / drying machine S) according to the present embodiment. FIG. 8 is a cross-sectional view of the outlet 28 in FIG.

As shown in FIG. 7, the outlet 28 is provided along the opening 2c from the front side of the outer tub cover 2d, and flow paths 28b and 28c are formed therein. A bellows pipe joint 27b is connected to the inlet of the outlet 28, and a nozzle 28d is formed at the outlet of the flow path 28c.
The inner diameter of the opening 2c of the outer tub cover 2d and the inner diameter of the opening 3a of the rotating drum 3 are set to be substantially the same so that clothing does not enter between the rotation drum 3 and the outer tub cover 2d. For this reason, the outlet portion 28a of the outlet 28 is formed so as to jump out from the inner peripheral surface of the opening 2c, and the nozzle 28d opens toward the inside of the rotary drum 3. By doing so, the wind blown from the nozzle 28d directly hits the clothing in the rotary drum 3.
In addition, if the amount of protrusion of the outlet portion 28a is too large, the movement of clothing is hindered during washing or drying. Therefore, as shown in FIG. 7, the nozzle 28d is formed into a flat slit shape to reduce the amount of protrusion, and the opening 2c The surface shape of the outlet portion 28a is changed smoothly. Further, the flow path 28b and the flow path 28c are configured such that there is no useless protrusion or a sudden change in the flow direction, and the flow path area gradually decreases toward the nozzle 28d. By doing so, it is possible to reduce the pressure loss and fluid noise that occur when high-speed wind flows through the flow paths 28b and 28c.

The flow path 28b of the blow-out port 28 is provided with a detergent supply port 34 for supplying a high concentration detergent solution into the flow path 28b. The detergent supply port 34 is connected to the discharge port of the detergent pump 32 (see FIG. 4) via the detergent hose B (33).
The high-concentration detergent supply means connects the room B (13c) (see FIG. 6) of the detergent container 13 (see FIG. 6) for storing the high-concentration detergent liquid to the detergent pump 32 (see FIG. 4). It has a pipe 13d, a detergent hose A (31), and a detergent hose B (33).
The liquid detergent stock solution introduced into the liquid detergent charging chamber 15 (see FIG. 6) is diluted with water supplied from the liquid detergent water supply electromagnetic valve 11c to generate a high-concentration detergent solution. The generated high-concentration detergent liquid is stored in the room B (13c) of the detergent container 13. The high-concentration detergent liquid stored in the room B (13c) is sent to the detergent supply port 34 by the detergent pump 32.

The production | generation of the mist of a high concentration detergent liquid is demonstrated.
The blower unit 24 (see FIG. 5) is operated to blow high-speed wind from the nozzle 28d of the blowout port 28. The liquid detergent water supply electromagnetic valve 11c (see FIG. 3) is opened to supply water to the liquid detergent charging chamber 15 (see FIG. 6). Further, the detergent pump 32 (see FIG. 4) is operated at almost the same timing as when the liquid detergent water supply electromagnetic valve 11c is opened.
The level of the liquid detergent in the liquid detergent charging chamber 15 rises while being diluted with water. When the siphon 15a passes, the liquid detergent flows down into the room B (13c) of the detergent container 13 below the siphon 15a. The concentration of the flowing liquid detergent is very high at the beginning of water supply, but is gradually diluted and finally becomes zero.

The liquid detergent (high-concentration detergent liquid) in the room B (13c) is sent to the detergent supply port 34 by the detergent pump 32 and supplied into the flow path 28b (arrow 30 shown in FIG. 8).
The liquid detergent (high-concentration detergent liquid) flows through the flow path 28b together with the air from the blower unit 24, and flows out from the nozzle 28d into the rotary drum 3.
Since there is a large speed difference between the high-speed wind and liquid detergent (high concentration detergent liquid) blown out from the nozzle 28d and the air in the rotary drum 3, the liquid detergent (high concentration detergent liquid) is vigorously stirred by this speed difference. And mist. Then, it diffuses into the rotating drum 3 together with the high-speed wind blown from the nozzle 28d.

At this time, the rotating drum 3 is rotating at a rotation speed (for example, 40 to 50 rotations / minute) at which the clothes are lifted and dropped, and the clothes are sequentially lifted near the nozzle 28d. For this reason, the mist liquid detergent (high concentration detergent liquid) spreads and penetrates the clothes substantially uniformly, acts on the dirt, and the dirt is lifted from the clothes. Further, since the mist of the high-concentration detergent is sprayed on the clothing together with the high-speed wind, it can be efficiently distributed over the entire clothing such as the clothing gap and the clothing on the back side.
The flow rate of the liquid detergent (high-concentration detergent liquid) supplied to the detergent supply port 34 needs to be set according to the air volume and the wind speed in order to efficiently mist and spread the clothes uniformly. If the flow rate is small, the uniformity is improved, but it takes time to wet the garment. If the flow rate is high, the uniformity is deteriorated and unevenness of moisture occurs, but it can be moistened in a short time. For example, when the air volume is 1.5 m ³ / min and the wind speed is 90 m / s, the flow rate is preferably about 0.05 to 0.2 L / min.

The control device 60 opens the drain valve 18, drains the wash water in the outer tub 2, drives the motor 4, and rotates the rotating drum 3 at a high speed, thereby centrifugally dehydrating the clothes.

The control device 60 closes the drain valve 18, opens the main water supply electromagnetic valve 11b, and supplies rinsing water to the outer tub 2 to a specified water level (step S110).
When water is supplied to a specified water level, the controller 60 closes the main water supply electromagnetic valve 11b, drives the motor 4 and alternately rotates the rotating drum 3 in the forward and reverse directions at a low speed, thereby performing a “rinse” operation to rinse the clothes. Execute (Step S111). After the rinsing operation is completed, the control device 60 opens the drain valve 18 and drains the rinsing water in the outer tub 2, and then drives the motor 4 to rotate the rotating drum 3 at a high speed, thereby centrifugally dehydrating the clothes. (Step S112).
The rinsing (step S110 to step S112) is performed only once in the flowchart shown in FIG. 10, but the combination of “water supply—rinse—drainage / dehydration” may be performed a plurality of times. Further, when rinsing is performed a plurality of times, the controller 60 opens the flexible finishing agent water supply electromagnetic valve 11 d and supplies the flexible finishing agent into the outer tub 2 at the time of water supply in the final rinsing operation.

The control device 60 determines whether or not the course selected in step S102 is a “laundry drying course” (step S113).
If the course selected in step S102 is not the “laundry drying course” (No in step S113), the flow ends.
If the course selected in step S102 is the “laundry drying course” (Yes in step S113), the process proceeds to step S114, and the drying operation is executed (step S114).

In the drying operation, the control device 60 drives the fan motor 24a of the blower unit 24 at a high speed while rotating the rotating drum 3 at a low speed (30 to 50 revolutions / minute), energizes the heater 25, and performs a high speed operation. Hot air is blown into the rotary drum 3 to raise the temperature of the clothes and to evaporate moisture from the clothes. Further, the control device 60 opens the cooling water supply electromagnetic valve 11 e and supplies cooling water to a water cooling / dehumidifying mechanism (not shown) of the drying duct 21. High-temperature and high-humidity air containing moisture evaporated from the clothes is dehumidified by a water-cooled dehumidifying mechanism (not shown) of the drying duct 21.
In addition, since high-speed (90 m / s) wind is blown onto the clothing, drying progresses while stretching the wrinkles of the clothing, and a dry finish with less wrinkles can be realized.
The detection of the completion of drying is performed by the temperature sensor 70, and the control device 60 ends the drying operation when the drying of the clothes is detected.

Thus, the washing / drying machine (drum type washing / drying machine S) according to the present embodiment mists the high-concentration detergent liquid with the high-speed wind, diffuses and sprays it with the high-speed wind, and sprays it on the clothes. Can be distributed evenly between the clothing gaps and the clothing on the back side of the rotating drum 3. For this reason, the high concentration detergent solution acts evenly on the dirt adhering to the clothes, and the dirt can be lifted and easily removed. And since a washing operation is performed by supplying water, the detergency can be improved.
In addition, since the high-concentration detergent liquid is misted using the air blowing means provided in the washing and drying machine, additional equipment is unnecessary, without increasing the cost as in the washing machine described in Patent Document 3, It is possible to provide a washing and drying machine capable of obtaining a high detergency with an inexpensive method.

≪First modification≫
The washing / drying machine according to the present embodiment is not limited to the configuration of the above-described embodiment, and various modifications can be made without departing from the spirit of the invention.
For example, in the configuration of the above embodiment, when the high-concentration detergent solution is misted in step S105, the high-concentration detergent solution is misted with wind at substantially room temperature. Also good.
When the heater 25 is energized and warm air is used, the mist-converted high-concentration detergent liquid is warmed by the warm air, and the mist of the high-concentration detergent liquid having a high temperature is sprayed on the clothes. The detergent has a higher effect of activating and raising the dirt when the temperature is higher, and the detergency is improved. In addition, since the clothes are also warmed by the warm air, the temperature of the detergent sprayed on the clothes becomes high, and the cleaning power is improved.

≪Second modification≫
Further, before the high-concentration detergent solution is misted and sprayed (step S106), first, the control device 60 drives the motor 4 to rotate the rotating drum 3 at a low speed (for example, 30 to 50 rotations / minute). The fan motor 24a of the blower unit 24 is rotated at high speeds in the reverse direction, the heater 25 is energized, high-speed warm air is blown into the rotary drum 3, and the clothes are heated. The high concentration detergent solution may be supplied to the detergent supply port 34 by driving the pump 32, and the high concentration detergent solution may be misted and sprayed.
In this way, after warming the clothes in advance, since the highly concentrated detergent liquid that has been misted is sprayed on the clothes, the temperature of the detergent can be further increased, the detergent can be activated, and the detergency can be improved. .

<< Third Modification >>
In the washing / drying machine according to the present embodiment, as the high-concentration detergent generating means, water is supplied to the detergent tray 7 to generate a high-concentration detergent liquid (see step S105 in FIG. 10), and the generated high-concentration detergent liquid is used as the detergent. Although it has been described that the nozzle 28d is supplied from the supply port 34, the present invention is not limited to this.
For example, a high-concentration detergent production means for producing a high-concentration detergent solution at the bottom of the outer tub described in Patent Document 2 is provided, and the produced high-concentration detergent solution is pumped up with a circulation pump and supplied from the detergent supply port 34 to the nozzle 28d. A high-concentration detergent solution may be misted.
As a result, a high-concentration detergent solution can be generated even in powder detergent, and can be sprayed in the form of a mist, improving the cleaning power.
In the case of the washer / dryer according to this modification, the rinsing water was sucked with the circulation pump even during the rinsing operation while the blower fan was stopped, and was supplied to the nozzle 28d from the detergent supply port 34, thereby adhering to the outlet. The detergent can be washed away.
