Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum-type washing machine that performs operations such as washing, rinsing, and dewatering with a rotating drum (washing tub) having a rotating shaft arranged almost horizontally.

[0002]

2. Description of the Related Art Hitherto, many drum type washing machines having a rotating drum whose rotating shaft is arranged substantially horizontally have been proposed, and most of the washing machines used in Europe are of this type. This drum type washing machine can wash, rinse, and dehydrate by rotating a rotary drum.

A conventional drum type washing machine will be described.
FIG. 12 is an external view of the drum type washing machine. Reference numeral 1 denotes an outer box of a drum type washing machine which is formed in a substantially rectangular parallelepiped shape. Reference numeral 2 denotes a door provided on the front surface of the outer box 1 for opening and closing a loading / unloading opening for laundry, which is opened and closed laterally. Further, 7 is a detergent case in which a detergent or a softening agent is put in advance.

FIG. 13 is a vertical sectional view of the drum type washing machine. A water tank 3 is swingably mounted in the outer box 1 by a shock absorber (not shown) including a spring. Further, in the water tank 3, there is provided a rotating drum 5 which rotates about a rotating shaft 4 which is arranged substantially horizontally. Both of the water tank 3 and the rotary drum 5 are open at the front surface, and the front opening portions 3a and 5a are located side by side with the inlet / outlet opening 1a of the outer box 1 in the axial direction of the rotary shaft 4.

Numeral 6 is a substantially cylindrical door packing, one end of which is fixed to the peripheral edge of the inlet / outlet opening 1a of the outer box 1 and the other end of which is fixed to the peripheral edge of the front opening 3a of the water tank 3. Inside the body portion 6a of the door packing 6, a water stop portion 6b is formed near the one end (on the outer case 1 side). When the water stop portion 6b comes into close contact with the closed door 2, the inside of the water tank 3 is sealed, and water is prevented from leaking out through the inlet / outlet opening 1a.

A water supply nozzle 6c extending upward is formed in the body portion 6a so as to penetrate the body portion 6a. An upper end of the water supply nozzle 6c is connected to a water supply passage 10 described later. The lower end is located inside the body 6a and opens toward the other end (on the side of the water tank 3).

A bellows portion 6d is formed on the other end side of the body portion 6a with respect to the water supply nozzle 6c. Therefore, the door packing 6 can follow the movement of the water tank 3 that is swingably attached to the outer box 1 by expanding and contracting at the bellows portion 6d.

Further, 7 is a detergent case provided in the upper part of the outer box 1, in which the detergent and the softening agent are separately charged in advance. In the detergent room and the softening agent room in the detergent case 7, water supply channels 8a and 8b connected to the water supply respectively.
Are in communication.

When the water supply valve 9a is opened, water is supplied to the detergent chamber of the detergent case 7 from the water supply passage 8a, and the water flows down together with the detergent into the water supply passage 10 extending downward from the detergent case 7. As described above, this water supply passage 10 is provided with the water supply nozzle 6 of the door packing 6.
Since c is in communication, the washing liquid is supplied into the water tank 3 from the water supply nozzle 6c.

[0010]

However, the conventional drum type washing machine described above has the following problems.

As shown in FIG. 13, since the water supply nozzle 6c is provided in the body portion 6a, there is a distance from the water supply nozzle 6c to the front opening 3a of the water tank 3. Therefore, when the amount of the washing liquid is small, the force of blowing from the water supply nozzle 6c is weak,
The water accumulates in the lower part of the door packing 6 along the inner surface of the door 2 and is not supplied to the water tank 3.

Further, since the water supply nozzle 6c extends perpendicularly to the axial direction of the substantially cylindrical door packing 6, it is difficult to manufacture the door packing 6. 14
FIG. 6 is an explanatory view showing a manufacturing process of the door packing 6, showing a state in which the melted door packing material is poured into a central space formed by the molds 30a and 30b. After that, the door packing material is cooled and solidified, and the mold 30a,
Although 30b is opened in the directions of arrows V and W, the F1 portion in the water supply nozzle 6c cannot be released, and a special means is required. Therefore, it takes much time and cost to manufacture.

In the conventional drum type washing machine described above, the rotary shaft 4 is arranged substantially horizontally, but on the other hand, the rotary shaft 4 may be inclined so that the front side becomes higher. When the rotary shaft 4 is tilted, the visibility inside the rotary drum 5 is improved and workability is improved. However, the structure of the conventional door packing 6 cannot be applied to the drum type washing machine in which the rotating shaft 4 is inclined.

This is because the bellows portion 6d of the door packing 6 is
Since the main purpose is to cope with the shaking of the water tank 3 in the vertical direction, the dimension L in the depth direction is longer than the dimension H in the vertical direction (see FIG. 13). On the contrary,
In the drum type washing machine with the rotating shaft 4 tilted, the water tub 3 moves diagonally.
Cannot move smoothly.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a drum type washing machine in which a rotary shaft is inclined and which can effectively wash. And

[0016]

In order to achieve the above object, a drum type washing machine of the present invention is provided with an outer box having an inlet / outlet opening for loading and unloading laundry, and is swingable in the outer box. For opening and closing the inlet and outlet, a water tank having an opening on the front surface, a rotary drum mounted on the water tank, which rotates about a rotating shaft inclined at a predetermined angle, and having an opening on the front surface, , A water supply means for supplying water to the water tank, and a drive means for driving the rotating shaft.

This drum type washing machine is provided with a substantially cylindrical packing, one end of which is fixed to the peripheral edge of the inlet / outlet port and the other end of which is fixed to the peripheral edge of the opening of the water tank. Further, a single bellows portion having a large diameter in a direction substantially perpendicular to the axial direction of the rotating shaft is formed continuously with the other end. This bellows part is smaller than the axial dimension of the rotary shaft.
The dimension in the direction perpendicular to the axial direction is larger.
The water supply means includes a water supply channel for guiding water to the water tank.
In the front opening of the water tank on the bellows of the door packing.
The opposing vertical planes are approximately flat with respect to the axial direction of the rotary shaft.
A water supply nozzle extending in a row is provided, and the water supply means is provided.
Is connected to one end of the water supply nozzle .

In the drum type washing machine having the above construction, since the bellows portion of the door packing has a large diameter perpendicular to the axial direction of the rotary shaft, it is easy to expand and contract in the axial direction. In this case, when the water tank vibrates due to the rotation of the rotary drum or descends due to the weight of the washing liquid or the laundry, the water tank moves diagonally along the axial direction of the rotating shaft. Therefore, the bellows portion of the door packing can easily follow the movement of the water tank.

If the bellows portion of the door packing has a larger dimension in the direction perpendicular to the axial direction of the rotating shaft than in the axial direction of the rotating shaft, the bellows portion is more likely to expand and contract in the axial direction of the rotating shaft.

Further, the drum type washing machine of the present invention is provided with a water supply passage for guiding water to the water tank as water supply means. On the other hand, the bellows portion of the door packing is provided with a water supply nozzle extending substantially parallel to the axial direction of the rotating shaft, and the water supply passage is connected to one end of the water supply nozzle. As a result, the other end opening of the water supply nozzle is located near the front opening of the water tank and faces it, so that the water that has passed through the water supply nozzle from the water supply passage is almost supplied to the water tank.

Further, in the drum type washing machine of the present invention, the communication hole for communicating with the water tank in the bellows internal chamber formed in the bellows portion of the door packing faces the front opening of the water tank in the bellows portion.
It is installed on the vertical plane . Therefore, when water accumulates in the bellows internal compartment of the bellows, the water flows down from the communication hole to the water tank.

[0022] In addition, in the drum-type washing machine of the present invention, a vertical plane facing the water tank front opening of the bellows portion of the door packing
A circulation nozzle extending substantially parallel to the axial direction of the rotating shaft; a circulation path having one end communicating with the water tank and the other end connected to the circulation nozzle; and a pump member for sending water from the water tank into the circulation path. Is provided. Therefore, when the pump member operates, the water in the water tank is supplied again from the circulation nozzle to the water tank through the circulation passage.

Further, in the drum type washing machine of the present invention, the vertical surface facing the front opening of the water tank in the bellows portion of the door packing.
A blower nozzle extending substantially parallel to the axial direction of the rotating shaft, an air passage having one end communicating with the water tank and the other end connected to the air blow nozzle, and an air blowing means for sending air in the water tank to the air passage. ,
A cooling means for cooling the air passing through the ventilation passage and a heating means for heating the air provided downstream of the cooling means in the ventilation passage are provided.

Therefore, when the air blowing means is operated, the air in the water tank is guided into the ventilation passage and cooled by the cooling means, so that the moisture is condensed. The air dehumidified by dew condensation is heated by the heating means and then sent out from the air blowing nozzle into the water tank.

In the drum type washing machine of the present invention, a flat surface is formed on the body of the door packing, and the water supply nozzle, the circulation nozzle or the blow nozzle is arranged along the flat surface. That is, by making the body part of the substantially cylindrical door packing partly flat and arranging the water supply nozzle, the circulation nozzle or the blowing nozzle in that space, these nozzles can have a relatively large diameter.

Further, in the drum type washing machine of the present invention, the inlet / outlet of the outer box has a shape in which a part of the upper part is horizontally cut off from the whole circle. In this case, the door attached to the entrance / exit also has the same shape. Therefore, the entrance and exit and the door become smaller in the vertical direction.

Further, in the drum type washing machine of the present invention, the radial direction of the inlet / outlet port of the outer box is substantially vertical, and the radial direction of the opening of the water tank is in the axial direction of the rotary shaft inclined at a predetermined angle. Ri substantially perpendicular der for, of the outer box out put port and of the water tank
The distance to the opening is lower than the distance in the upper part.
The distance is short. That is, the upper part of the opening of the water tank is located farther away from the entrance of the outer box, and the lower part is located closer to the front side.

Further, in the drum type washing machine of the present invention, the back surface portion of the door located inside the outer case when the door is closed is perpendicular to the axial direction of the rotating shaft. by this,
The laundry rotating in the rotating drum hits the inner surface of the door and is less likely to hit the door packing.

Further, in the drum type washing machine of the present invention, the back surface of the door is partially formed with a vertical surface and is located on the front side of the water draining portion which is the base of the bellows portion of the door packing. Therefore, even if water is discharged from the water supply nozzle with a weak force and drips from the water draining portion, the water does not hit the back surface portion of the door.

[0030]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. It should be noted that members having the same names as those in the conventional technique shown in FIGS. 12 to 14 are denoted by the same reference numerals, and redundant description is omitted.

First, a first embodiment according to the present invention will be described. FIG. 1 is an external view of a drum type washing machine according to the present embodiment, and FIG. 2 is a vertical sectional view of the drum type washing machine. In these figures, 5b formed on the peripheral wall of the rotary drum 5 is a small hole, which connects the water tank 3 and the rotary drum 5 to each other. A fluid balancer 11 is fixed to the outside of the front opening 5a of the rotary drum 5. Incidentally, it may be fixed inside.

12a fixed to the back surface of the water tank 3 is
It is a stator of a drive motor that can rotate in forward and reverse directions. Further, 12b fixed to the rotating shaft 4 is a rotor. The driving force of the drive motor is transmitted to the rotating shaft 4 via the stator 12a and the rotor 12b.

Reference numeral 13 is a connection case in which a thread waste filter 14 is provided. The lint filter 14 removes foreign matters such as dust and lint from the washing liquid, and is, for example, a bag-shaped fine fiber or a basket-shaped fine resin grid. It is detachably attached so as to close a connection port of an external drainage channel 16 described later.

Reference numeral 15 is an internal drainage channel extending from the drainage port 3b provided at the bottom of the water tank 3 to the connection case 13. 1
An external drainage channel 6 extends from the connection case 13 to the outside of the outer case 1, and a drainage valve 17 is interposed. The drain valve 17 may be a pump.

The connection case 13 includes an air trap 18
A water level sensor 20 is connected via the pipe 19 and the pipe 19. The water level sensor 20 detects the pressure fluctuation in the pipe 19 to detect the water level in the water tank 3.

Next, the characteristic structure of this embodiment will be described. First, as shown in FIG. 2, the rotary shaft 4 of the rotary drum 5 is provided so as to be inclined so that the front side becomes higher. Similarly, the water tank 3 in which the rotary drum 5 is installed is also inclined. The front opening 3a, 5a of the water tank 3 and the rotary drum 5 and the entrance / exit 1 of the outer box 1
All of a are located side by side in the axial direction of the rotary shaft 4. As described above, since the water tank 3 and the rotary drum 5 are provided so as to be inclined so that the front side becomes higher, the visibility inside the rotary drum 5 is improved and the workability is improved.

Next, the inlet / outlet 1a of the outer box 1 and the door 2 attached to the inlet / outlet 1a will be described. The door 2 has a substantially box shape, and when it is closed, its bottom portion is located inside the outer box 1 (in the drawing, a rear surface portion 2a). This back side 2
a is a front opening 3a, 5a of the water tank 3 and the rotating drum 5.
Similarly to the above, it is perpendicular to the axial direction of the rotary shaft 4. As a result, the laundry rotating in the rotary drum 5 hits the inner surface portion 2a, and there is no risk of hitting the door packing 6 to be described later, causing abrasion, or catching on it and damaging the laundry.

Further, FIG. 3 shows a perspective view of the door 2 of the present embodiment as seen from the inside of the water tank 3. The edge portion 2b provided on the peripheral edge of the door 2 has a shape in which the upper portion is partially cut off horizontally. A flat portion 2d is formed on the upper portion of the body portion 2c forming the side portion of the door 2. Correspondingly, the inlet / outlet opening 1a of the outer box 1 also has a shape in which a part of the upper part is horizontally cut off from the entire circular shape.
That is, the door 2 and the entrance / exit 1 are configured to be small in the vertical direction.

As shown in FIG. 2, the entrance / exit 1a of the outer box 1
Is in the axial direction of the rotary shaft 4, and therefore is located higher than the front openings 3a, 5a of the water tank 3 and the rotary drum 5. Therefore, although the outer box 1 should originally have a high height, in the present embodiment, the height of the outer box 1 can be increased by making the doorway 1a and the door 2 smaller in the vertical direction. You don't have to.

Further, in this embodiment, the radial direction of the inlet / outlet opening 1a of the outer box 1 is vertical, but the water tank 3 and the rotary drum 5 are
The radial directions of the front opening portions 3a, 5a are perpendicular to the axial direction of the rotary shaft 4. That is, in FIG. 4, which is an enlarged view of the vicinity of the door 2 in FIG.
The distance to the front opening 3a is shorter in the lower portion S2 than in the upper portion S1. In other words, since the water tank 3 is close to the lower portion of the access port 1a, which is the working area for the user, the rotary drum 5 therein can be easily reached and the workability is improved.

Next, the substantially cylindrical door packing 6 having one end fixed to the peripheral edge of the inlet / outlet 1 of the outer box 1 and the other end fixed to the peripheral edge of the front opening 3a of the water tank 3 will be described. As shown in FIG. 4, the door packing 6 is continuous with the other end (on the side of the water tank 3) and has a single diameter whose diameter increases in a direction substantially perpendicular to the axial direction of the rotating shaft 4 (arrow P in the drawing). The bellows portion 6d is formed. In particular, since the bellows portion 6d is configured such that the radial dimension Y is larger than the axial dimension Z of the rotary shaft 4, the bellows portion 6d can be easily expanded and contracted in the axial direction of the rotary shaft 4.

Since the water tub 3 is swingably attached to the outer box 1, it vibrates by the rotation of the rotating drum 5 or when it descends due to the weight of the washing liquid or the laundry, that is, the rotating shaft 4 is rotated. Move in the axial direction of. Therefore, according to the configuration of the bellows portion 6d, the water tank 3 can be smoothly moved smoothly, and vibration and noise during operation can be reduced.
Further, since the bellows portion 6d has a larger diameter than the body portion 6a, the door packing 6 can be easily manufactured.

A water supply nozzle 6c extending substantially parallel to the axial direction of the rotary shaft 4 is formed in the bellows portion 6d, and one end of the water supply nozzle 6c is connected to a water supply passage 10 communicating with the detergent case 7. . Here, since the bellows portion 6d is provided continuously to the other end (on the side of the water tank 3), and the other end opening of the water supply nozzle 6c faces the front opening 3a of the water tank 3, the water supply nozzle 6c is The distance from the other end opening to the front opening 3a is short.

Therefore, the water supply nozzle 6 passes through the water supply passage 10.
The washing liquid discharged from c is almost certainly supplied into the water tank 3. In particular, since the water tub 3 and the rotating drum 5 are inclined, the washing liquid is directly supplied to the laundry in the rotating drum 5.

Incidentally, FIG. 5 shows another example of the water supply nozzle 6c. Although the water supply nozzle 6c shown in FIG. 4 extends outward from the bellows portion 6d, it may extend inward as shown in FIG.

Further, since the water supply nozzle 6c extends substantially parallel to the axial direction of the rotary shaft 4 (direction of arrow P in FIG. 4), the following effects can be obtained. That is, FIG. 6 is an explanatory view showing a manufacturing process of the door packing 6, in which the mold 3
It shows a state in which the melted door packing material is poured into the central space formed by 0a and 30b. After this, the door packing material is cooled and solidified, and the molds 30a, 3
0b is opened in the directions of arrows V and W, but the water supply nozzle 6
The F2 part in c is easily released. Therefore, time and cost can be reduced as compared with the conventional technique.

FIG. 7 is a front view of the door packing 6 of this embodiment. As shown in the figure,
A flat surface portion 6e is formed on the upper portion of the body portion 6a, and a water supply nozzle 6c is located immediately above the flat surface portion 6e. In addition, 6 provided adjacent to this water supply nozzle 6c
Numerals f and 6g are a circulation nozzle and a blowing nozzle which will be described later.

As described above, the flat portion 6e is provided on the body portion 6a of the door packing 6, and the nozzles 6c, 6 are provided in the space.
By positioning f, 6g, these nozzles 6c, 6g
The diameter of f, 6g can be made large. Therefore, each capacity becomes large.

As a further feature of the door packing 6 of this embodiment, an enlarged sectional view of the door packing 6 is shown in FIG. As shown in the figure, in the lower portion of the bellows portion 6d, a communication hole 6i for communicating the bellows internal chamber 6h with the water tank 3.
Are formed. By this, even if the water supply nozzle 6
The washing liquid supplied from c (see FIG. 2) is the back surface 2 of the door 2.
Even if it reaches the lower part of the door packing 6 along a and collects in the bellows interior drawing room 6h of the bellows part 6d, the washing liquid naturally flows out from the communication hole 6i to the aquarium 3 due to the inclination. Therefore, the washing liquid supplied from the water supply nozzle 6c is reliably sent to the water tank 3. In addition, there is no inconvenience that the detergent liquid accumulates in the bellows interior chamber 6h and becomes dirty.

Next, the structure of the circulation passage and the ventilation passage provided in this embodiment will be described. FIG. 9 is a sectional view of the drum type washing machine in a vertical direction different from that in FIG.
As shown in the figure, the bellows portion 6d of the door packing 6 has a circulation nozzle 6f extending substantially parallel to the axial direction of the rotating shaft 4.
Is provided.

A circulation passage 21 is provided, one end of which is connected to the circulation nozzle 6f and the other end of which communicates with the external drainage passage 16 upstream of the drainage valve 17. When the circulation pump 22 provided in the circulation passage 21 operates, the water tank 5
The washing liquid therein is pumped up to the circulation passage 21 through the drainage passages 15 and 16, and is again supplied into the water tank 3 through the end opening of the circulation nozzle 6f formed in the bellows portion 6d.

FIG. 10 is a sectional view of the drum type washing machine in a vertical direction different from FIGS. 2 and 9. As shown in the figure, the bellows portion 6d of the door packing 6 is provided with a blower nozzle 6g extending substantially parallel to the axial direction of the rotary shaft 4. Also, one end is the blower nozzle 6g
3 and the other end is provided at the bottom of the water tank 3
An air passage 23 communicating with c is provided.

When the air blower 24 provided in the air passage 23 is operated, the air in the water tank 3 flows from the intake port 3c into the air passage 2
3 is sucked and cooled by the cooling device 25. As a result, the moisture of the air is removed by dew condensation, and then the air is heated by the heating device 26. Then, the air is blown again into the water tank 3 through the end opening of the blow nozzle 6g formed in the bellows portion 6d.

Here, the bellows portion 6d is continuously provided at the end of the door packing 6 on the side of the water tank 3, and the end openings of the nozzles 6f and 6g are the same as the water supply nozzle 6c.
Since it faces the front opening 3a, the circulating washing liquid or air is efficiently sent into the water tank 3.

Next, the operation of the drum type washing machine of this embodiment constructed as described above will be described. In FIG. 2, the detergent and the softening agent are put into the detergent case 7, the laundry is put into the rotary drum 5, and the door 2 is closed. At this time, the water blocking portion 6b of the door packing 6 is attached to the body portion 2c of the door 2.
And the inside of the water tank 3 is sealed, and the door 2 is automatically locked and locked so as not to open until unlock control is performed.

In the washing step, first, the water supply valve 9a is opened to supply tap water to the detergent chamber in the detergent case 7 through the water supply passage 8a. Water is supplied to the laundry in the rotary drum 5 from the water supply nozzle 6c of the door packing 6 together with the detergent. When the water level sensor 20 detects that the washing liquid in the water tank 3 has reached the predetermined water level, the water supply valve 9a is closed and the rotary drum 5 is rotated.
The rotation of the rotary drum 5 may be started before the water level sensor 20 detects the predetermined water level.

During the washing process, the circulation pump 22 (see FIG.
(See reference) is driven to send the washing liquid in the water tub 3 to the circulation path 21, and is directly supplied again to the laundry in the rotary drum 5 from the circulation nozzle 6f. In this way, by circulating the washing liquid, the detergent is dissolved and further stirred, so that the laundry can be efficiently washed. Further, since the circulating washing liquid passes through the connection case 13 and foreign matters are removed by the lint filter 14, washing can be performed more efficiently. The circulation pump 22 may be operated constantly or intermittently.

When the washing process is completed, the drain valve 17 (see FIG.
(See) to drain the washing liquid and perform the next rinsing step.
In the rinsing process, the rotary drum 5 is rotated at a high speed to dehydrate the washing liquid in the laundry, and a rinse dehydration chart, and tap water is put into the rotary drum 5 to a predetermined water level, and the rotary drum 5 is rotated at a constant speed. The rinsing dehydration chart and the rinsing chart are alternately performed a plurality of times.

First, when the drainage is completed, the rinse dehydration chart is executed, and the rotating drum 5 rotates at high speed to spin off the washing liquid in the laundry by centrifugal force. The washing liquid is discharged from the small hole 5b of the rotary drum 5 to the water tub 3, propagates to the lower part of the inner wall thereof, and is discharged from the drain port 3b.

Next, the drain valve 17 is closed and the water supply valve 9b is opened to supply water to the softening agent chamber of the detergent case 7 through the water supply passage 8b. Water is supplied into the water tank 3 through the water supply nozzle 6c together with the softening agent. After the water is supplied to the predetermined water level, the rotary drum 5 is rotated to execute the rinse chart. When the rinse chart is completed, the rinse dehydration chart is executed again.

During execution of the rinsing / dehydration chart, the water supply valve 9b is opened to supply tap water from the water supply nozzle 6c into the rotary drum 5, and the tap water is permeated into the laundry by the dehydrating force to remove the water inside the laundry. The detergent may be removed. Further, during execution of the rinse chart, the circulation pump 22 (see FIG. 9) may be operated to circulate the washing liquid in the water tub 3.

When the rinsing process is completed, the drain valve 1
7 is opened to drain the washing liquid, and the rotary drum 5 is rotated at a high speed to execute the finishing dehydration process.

After the finishing dehydration process, a drying process is executed. That is, the air blower 24 (see FIG. 10) is driven while rotating the rotary drum 5 at a constant speed to drive the air in the water tank 3 into the air passage 2
Aspirate into 3. First, this air flow is cooled by the cooling device 25, the moisture in the air becomes dew condensation, and dehumidified. The condensed water descends through the ventilation passage 23, flows into the water tank 3 through the intake port 3c, and is discharged from the drainage passages 15 and 16.

The dried air stream is heated by the heating device 26 to become hot air, which is blown from the blower nozzle 6g to the rotary drum 5.
Supplied within. The dried hot air comes into contact with wet laundry, absorbs moisture, and is sucked into the ventilation passage 23 again. The laundry is dried by repeating this. In particular, the blower nozzle 6g allows hot air to easily reach the back of the rotary drum 5 and directly contacts the laundry, so that the laundry can be efficiently dried. The blower 24 may be operated constantly or intermittently.

The humidity or temperature in the rotary drum 5 is detected by a humidity sensor or a temperature sensor (not shown), and the drying process is terminated when a predetermined value set in advance is detected. It should be noted that the drying process may be finished after a predetermined time.

Next, a second embodiment according to the present invention will be described. FIG. 11 shows a part of a vertical cross section of the drum type washing machine of the present embodiment. The present embodiment is different from the first embodiment only in the configuration of the door 2, and the other configurations are the same.

As shown in FIG. 11, the door 2 of the present embodiment.
By forming a vertical surface 2e on a part of the back surface portion 2a, the back surface portion 2a is positioned at the base of the bellows portion 6d of the door packing 6 and on the front side of the draining portion 6j which is a boundary with the body portion 6a. ing. As a result, when the washing liquid is discharged from the water supply nozzle 6c with a weak force and drips from the water draining portion 6j, the washing liquid does not reach the back surface portion 2a of the door 2 and directly drops into the water tank 3. Therefore, the washing liquid is the back surface 2a of the door 2.
There is no inconvenience such as falling down along the path and accumulating under the door packing 6.

[0068]

As described above, in the drum type washing machine of the present invention, since the door packing can easily follow the diagonal movement of the water tank, noise and vibration can be reduced. Further, since the bellows portion has a shape that can be easily manufactured, the cost can be reduced.

Further, a water supply nozzle, a circulation nozzle, and a blowing nozzle extend from the bellows portion of the door packing substantially parallel to the axial direction of the rotating shaft. Therefore, when the door packing is manufactured by molding with a mold, the door packing can be released more easily than before, so that the time and cost for manufacturing can be reduced.

Further, since the bellows inner compartment of the door packing is provided with the communication hole communicating with the water tank, even if the washing liquid is collected in the bellows inner compartment, it can be discharged into the water tank. Therefore, there is no inconvenience that the bellows interior room is contaminated with the washing liquid.

Further, in the drum type washing machine of the present invention, by circulating the washing liquid through the circulation path, the dissolution of the detergent is promoted and the washing effect is enhanced. Further, by providing an air passage for dehumidifying and heating the air in the water tank, the dehydrated laundry can be dried.

In particular, both the circulation nozzle and the blower nozzle to which these circulation passage and ventilation passage are connected and the water supply nozzle to which the above-mentioned water supply passage is connected have an end opening on the side where the water or air is blown out of the water tank. It is located near the opening and is opposed to the opening. Therefore, the water and air blown out from these nozzles are surely supplied to the laundry in the water tank, that is, the rotating drum, so that effective washing can be performed.

A flat surface is formed in the body of the door packing to provide a space, and the nozzles are located along the flat surface. Therefore, the diameter of each nozzle can be increased by the amount of the space provided, and the capacity of the water supply passage, the circulation passage, and the ventilation passage is increased.

Further, since the door and the inlet / outlet of the outer box to which the door is attached in the drum type washing machine of the present invention are both vertically small, the drum type washing machine has a structure in which the rotary shaft is inclined. However, it is not necessary to increase the height of the outer box. Therefore, it is easy to use.

Further, since the inlet / outlet of the outer box is vertically provided in the radial direction, the door can be opened / closed in the horizontal direction and the operability is good. In particular, since the rotary drum is configured to be close to the lower part of the entrance / exit opening, which is a working area for the user, the rotary drum can be easily reached and the workability is good.

Further, if the back surface of the door is perpendicular to the axial direction of the rotary shaft, the laundry rotating in the rotary drum will not easily hit the door packing. Therefore, it is possible to prevent the laundry from hitting the door packing and being worn, or the laundry from being caught by the door packing and being damaged.

On the other hand, when the vertical surface is formed on the back surface of the door, the washing liquid supplied from the water supply nozzle can be prevented from dropping onto the door, and the washing liquid is directly poured into the water tank or the rotary drum.
