DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a dehydrating/drying/washing machine capable of performing washing, rinsing, dehydrating, and drying operations of laundry items.

[Prior Art] Recently, the inventors of this application have devised a dehydrating/drying/washing machine as described below. This dehydrating/drying/washing machine has an outer tank that can contain water inside the case body, a support that is rotatable around a vertical axis inside the outer tank, and a support that is rotatable around a vertical axis. It has a structure in which an inner tank for storing items to be washed is rotatably arranged around a horizontal axis.

The items to be washed are washed by rotating the inner tank around the horizontal axis while supplying water to the outer tank so that the water level reaches the inside of the inner tank containing the items to be washed. It has become.

Further, after draining the water in the outer tank, the support body and the inner tank are rotated at high speed around the vertical axis, thereby dewatering the items to be washed. Furthermore, by rotating the inner tank around the horizontal axis and supplying 1°C of E and S to the inner tank to increase its internal temperature, the items to be washed after dehydration are dried.

[Problems to be Solved by the Invention] However, in the above dehydrating/drying/washing machine, the lower end of the hot air supply passage for supplying hot air into the inner tank is configured to open into the inside of the outer tank. Therefore, the bubbles generated during the above-mentioned washing operation easily enter the opening of the hot air supply passage, and these bubbles flow out from the hot air supply passage into the inner tank during the subsequent rinsing, dehydration, and drying operations. , there was a risk of staining the items being washed.

This invention was made with attention to such problems, and its purpose is to prevent the washing operation from ending even if bubbles generated during the washing operation enter the opening of the hot air supply passage. To provide a dehydrating/drying washer which can later discharge and remove the foam from a hot air supply passage, and can surely prevent the possibility that the items to be washed will be soiled by the foam during rinsing and dehydration operations and drying operations. There is a particular thing.

[Means for Solving the Problems] In order to achieve the above object, the dehydrating/drying/washing machine of the present invention includes an outer tank, a support body rotatably supported around a vertical axis in the outer tank, , an inner tank supported rotatably around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal axis on the support body, and an inner tank having a large number of small holes in the peripheral wall, and a water level inside the inner tank. a washing driving means that performs a washing operation by rotating the inner tank around the horizontal axis or the inclined axis with water stored in the outer tank so that the water reaches the outer tank, and items to be washed stored in the inner tank; ,
a dewatering section WIJE stage that performs a dewatering operation by rotating a support body integrally with the inner tank at high speed around the vertical axis while the items to be washed after being washed are stored in the inner tank; and the inner tank. a drying drive means for performing a drying operation by rotating the inner tank around the horizontal axis or the inclined axis with items to be washed after dehydration stored therein; and heating means for supplying hot air into the interior. The heating means includes a hot air supply passage that opens into the inside of the outer tank, and the heating means is configured to blow air from the hot air supply passage toward the inside of the outer tank even when the drying operation is not performed. This is what I did.

Furthermore, instead of the configuration in which the heating means blows air even when the heating means is not in the drying operation, a cleaning stage may be provided in which water is supplied into the hot air supply passage to clean the inside of the passage.

[Function] In the dehydrating/drying/washing machine configured as described above, water is stored in the outer tank so that the water level reaches the inside of the inner tank, and the inner tank is filled with water without any items to be washed in the inner tank. The items to be washed are washed by rotating the tank by the washing drive means. Further, with the items to be washed stored in the inner tank, the support body is rotated at high speed integrally with the inner tank by the dewatering drive means, thereby dewatering the items to be washed. Further, with the items to be washed after dehydration stored in the inner tank, the inner tank is rotated by the drying drive means, and at the same time, warm air is supplied into the inner tank from the hot air supply passage of the heating means. By doing so, the items to be washed are dried.

(Operation) Next, an outline of the operation of the dehydrating/drying/washing machine configured as described above will be explained with reference to FIG. After putting the items to be washed inside, close the inner tank lid 37 and the main body opening/closing lid 4, and operate the start switch (not shown). The operations are performed automatically in sequence. That is, (a> Water supply operation by the water supply device 81 (b) 1st

The dewatering operation <i> based on the rotation of s21, the drying operation based on the warm air supply by the hot air supply device 94 and the rotation of the inner tank 30 by the first driver 1fl176. During this time, the control circuit 111 positions the inner tank 21 or the inner tank 30 based on a detection signal from a sensor (not shown).

Next, each of the above operations will be explained in detail.

Now, when washing is performed with the items to be washed stored in the inner tank 30, the drain valve 85 is closed, the spring clutch 71 is in the disconnected state, and the first drive mechanism 76 is formed. The brake body 75 is in a braking state and the middle tank 2
1 rotation is regulated. In this state, the water supply valve of the water supply device 81 is opened, and water is supplied into the outer tank 15 from the water supply port 82. Then, when the water level inside the outer tank 115 reaches the inside of the inner tank 30 and reaches the normal water level Wn, the seed part movement motor 51 is rotated, and the inner tank 3
0 is rotated about the horizontal axis X-X and the washing operation is initiated.

During this washing operation, the spherical object [30 containing the object to be washed is rotated around the horizontal axis X-X, and as the object rotates, the object to be washed is rolled by the plurality of reversing protrusions 34, 40, etc. While washing, so-called washing is performed. Therefore, the amount of water used when washing can be reduced. In addition, since there is almost no twisting or tangling of the items to be washed, the washing operation can be carried out effectively without causing any damage to the items being washed. It is possible to automatically shift from the washing operation to the draining operation and the dewatering operation without the need for troublesome work of correction.

In addition, when rinsing is performed after washing the laundry items, the inspection motor 51 performs the following operations as in the case of washing.
The inner tank 30 is rotated via the first drive mechanism 76 . In addition, by opening the water supply valve of the water supply device 81, water is supplied from the water supply port 82 toward the outer peripheral upper surface of the inner tank 30, and the rinsing water in the outer tank 15 passes through the overflow port and overflow hose 87 (not shown). The water level is maintained at a constant level. Therefore, while the rinsing water is replaced in sequence, the water from the water supply port 82 effectively washes away the bubbles adhering to the outer peripheral surface of the inner tank 30 and the objects to be washed in the inner tank 30. .

Further, when dewatering is performed after washing the laundry, the spring clutch 71 is connected to form the second drive mechanism 77, and the brake body 75
is placed in a non-braking state, and rotation of the inner tank 21 is allowed. In this state, when the inspection motor 51 is rotated, the inner tank 21 and the inner tank 30 are rotated at high speed around the vertical axis Y-Y through the second driving m tree 77, and the washing object is rotated at high speed around the vertical axis Y-Y. is dehydrated. Therefore, the rotation axis of the inner tank 30 containing the items to be washed is changed from the horizontal axis X-X to the vertical axis Y-Y during the transition from the washing operation or the rinsing operation to the dewatering operation without changing the posture of the fence. This allows the process to be carried out smoothly and in a short period of time.

In addition, when drying is performed after dehydrating the items to be washed, the first drive IH! ! The inner tank 30 is rotated around the horizontal axis X-X via the fan motor 96 and the heater 98, and hot air is generated from the hot air source 95 of the hot air supply device 94. and the warm air connects to 100
．． The warm air is supplied into the inner tank 30 via the hot air supply passage 99, the air blower r:+ 101, and the rear shaft portion 31, and is discharged from each small hole 35. Therefore, the drying operation can be effectively performed by blowing warm air onto the items to be washed while rolling the items.

During this drying operation, the hot and humid air in the inner tank 30 is guided into the expanded cooling chamber 88 through the overflow hose 87 from an overflow port (not shown) provided on the outside 41t15 that also serves as a hot air exhaust port, Its overflow hose 87, expansion cooling chamber 88
etc. are discharged to the outside. Therefore, the hot and humid air in the inner tank 30 is not directly discharged to the outside.

In addition, especially in this example, as is clear from FIG.
When the washing operation is completed and the water in the outer tank 15 is drained, the fan motor 96 of the hot air supply device 94 is temporarily activated, and the lower end air outlet 101 of the hot air supply passage 99 is activated.
Air is blown from the inside of the outer tank 15. Therefore, even if bubbles generated during the washing operation enter the lower end opening of the hot air supply passage 99, the bubbles are removed by the air blowing into the hot air supply passage 99.
It is discharged from inside 9 into outer tank 15. Therefore, during subsequent rinsing and dehydration operations, drying operations, etc., there is no possibility that bubbles will flow out from inside the hot air supply passage 99 and the items to be washed will be contaminated by the bubbles. Particularly, by discharging the bubbles in the nine passages before rinsing, it is effective to prevent the rinsing effect from deteriorating.

[Another Embodiment] Next, another embodiment of the present invention will be described based on FIG. 5.

In this embodiment, a cleaning device 105 as a cleaning means is provided inside the main body cover 2, in place of the configuration in which the bubbles in the hot air supply passage 99 are discharged and removed by blowing air from the hot air supply device 94 in the previously described embodiment. It is being A water supply pipe 103 of a cleaning device 105 equipped with an electromagnetic valve 102 is extended into the hot air supply passage 99, and a plurality of injection holes 104 facing the air outlet 101 are provided at its tip. Then, as shown by the two-dot chain line in FIG. 4, when the washing operation is completed and the water in the outer tank 15 is drained, there is a period of 196 hours until dehydration is started. $1.02 opens this cleaning device 1
Water is injected into the hot air supply passage 99 from the injection hole 104 of 02, and the inside of the passage 99 is cleaned.

Therefore, even if bubbles enter the hot air supply passage 99, the bubbles are washed and discharged into the outside 1115, and the bubbles flow out from the hot air supply passage 99 during subsequent dehydration or drying operations. It is possible to reliably prevent the possibility that the items to be washed will be soiled.

[Modification] Note that the present invention is not limited to the configuration of the embodiment described above, and can be modified and embodied as follows.

(1) The inner tank 21 is formed into a substantially cylindrical shape using a wire mesh or the like, and the mesh on the peripheral wall is used as a drainage part, or a plurality of columns are combined to form a substantially cylindrical framework, and the gaps between each column are formed. Alternatively, a stainless steel plate or the like may be formed into a cylindrical shape with a bottom, and a drain hole may be provided through the peripheral wall and bottom wall.

(2) The inner tank 30 is rotatably supported around an inclined axis that is inclined at a predetermined angle with respect to the horizontal axis XX.

(3) Air blowing operation of hot air supply device 94 or cleaning device 1
The cleaning operation No. 02 is configured to be temporarily performed at an arbitrary timing from around the end of the draining operation after the completion of the washing operation to around the end of the next dewatering operation.

[Effect of the invention] Since this invention is configured as explained above,
Even if the bubbles generated during the washing operation enter the opening of the hot air supply passage, the bubbles can be discharged and removed from the hot air supply passage after the washing operation is completed, and during the rinsing, spin-drying, and drying operations. This has the excellent effect of reliably preventing the possibility that the items to be washed will be soiled by foam.
