Description

  The present invention relates to a drum-type washing machine having a drum that rotates about a horizontal axis or an inclined axis, and more particularly to a drum-type washing machine having a clothing input port that is opened and closed by a door provided on the front surface of a casing.

  In general, a drum-type washing machine has a configuration in which a cylindrical bowl-shaped drum is rotatably arranged around a horizontal axis or an inclined axis inside an outer tub disposed in a substantially box-shaped casing. The laundry is housed in the drum, and the laundry is washed by rotating the drum while water is stored in the outer tub. Also, in a drum type washing machine having a drying function, when washing is completed, the laundry can be dried by feeding heated air into the outer tub while slowly rotating the drum. Yes. In many of these drum type washing machines, a clothing input port for putting clothes into and out of the drum is provided on the front surface of the housing, and a door for opening and closing the clothing input port is provided on the housing. And when the door is opened, it is comprised so that the opening for clothing input provided in the end surface of the drum may look through the opening formed in the front surface of the outer tub.

  One of the major consumer dissatisfaction with such drum-type washing machines is that it is difficult to put clothes in and out. That is, in general households, such a drum-type washing machine is often installed in a washing pan installed on the floor of a washroom, but the position of the clothing input port is low, so that clothes can be taken in and out of the drum. It was necessary for the user to bend down and bend his knees, so the usability was not always good. In order to eliminate such dissatisfaction, in recent years, a structure in which the rotation axis of the drum is inclined and the opening on the front surface of the drum faces obliquely upward has been widely used (see, for example, Patent Document 1). However, even with such a structure, for those who are accustomed to the operability of the spiral washing machine, its usability is not necessarily good enough, especially that it is difficult to take out clothes on the inner bottom of the drum. The problem remains.

  In order to cope with the above problem, a drum-type washing machine is also commercially available in which the position of the clothes insertion port is increased by installing the drum at a relatively high position inside the housing (see Non-Patent Document 1). ). However, there is a limit to trying to raise the drum to a high position while maintaining the overall height (about 1000 mm) of a conventional drum-type washing machine. If importance is placed on usability, the overall height of the washing machine can be increased. It is necessary to increase the position, and consequently the position of the clothing input port.

  However, a water faucet (water faucet) is usually provided on the standing wall on the back side of the place where the washing machine is installed. In general, the height of the water faucet is about 1100 to 1200 mm above the floor. For this reason, if the overall height of the washing machine is increased, the casing may hit the faucet and the washing machine may not be installed.

With this configuration, the strength of the fixing portion between the upper surface plate and the side surface plate is improved, which contributes to the improvement of the strength of the entire casing.

  As a specific aspect of the present invention, the water supply valve is provided with a detergent charging portion for charging detergents contained in a detergent container that can be pulled out forward into the outer tub with water supplied from the water supply valve. The water outlet of the water supply valve and the tap water inlet of the detergent charging part can be directly connected. Thereby, a detergent injection | throwing-in part and a water supply valve can be stored in the space of the width | variety of a grade a little larger than the width | variety of a detergent container.

  The drum-type washing machine according to the present invention preferably includes a bath water pump for supplying bath water to the outer tub, and the bath water pump is also disposed at a high portion before the dropping portion. It is good to have a configuration.

  According to this configuration, since the bath water pump can also be arranged at a position equivalent to or higher than the detergent container, water remains in the water supply path from the bath water pump to the detergent container when the bath water supply is stopped. Can be prevented.

  Further, in the drum type washing machine according to the present invention, the water supply unit including the water supply valve, the bath water pump, and the detergent charging unit, and the air sucked from the outer tub to dry the laundry again into the outer tub A fan that produces a flow, a fan motor, a heater that heats the air sent into the outer tub, and a drying filter that removes foreign matter (such as lint, dust, and pollen) mixed in the air sucked from the outer tub It is preferable that the water supply unit and the drying unit are arranged side by side in the upper space in the housing and in a higher part in front of the dropping portion.

  According to this configuration, the drop portion is provided on the rear side of the upper surface of the housing, and even when the upper space in the housing is narrowed in the depth direction, the water supply unit and the drying unit are effectively used in the space. Can be placed properly. Thereby, the freedom degree of arrangement | positioning in the housing | casing of various members other than a water supply unit and a drying unit becomes large, for example, it secures the lower space of an outer tank and uses it for arrange | positioning the member of another objective and a use. It becomes possible.

  Further, as one aspect of the above configuration, in the water supply unit, the detergent charging unit and the water supply valve provided behind the detergent inlet and the bath water pump are arranged side by side, and the drying unit has Can be configured such that a fan, a fan motor and a heater, and a filter chamber in which a drying filter is housed are arranged side by side.

  According to this configuration, in the water supply unit, the flow of water from the water supply valve and the bath water pump to the outer tub via the detergent charging unit becomes smooth, and the water supply path can be easily routed. Further, in the drying unit, a part of the filter chamber in which the drying filter is housed faces the front surface of the housing, so that the drying filter can be installed so as to be drawn forward in the same manner as the detergent container. This facilitates cleaning of the drying filter. In addition, each member can be appropriately arranged in a narrow space in each of the water supply unit and the drying unit to achieve compactness and space saving.

  In order to surely avoid interference between the faucet and the housing when installing the washing machine on a general washing pan, for example, the drop portion is 70 mm forward from the rear surface of the housing. It is good to set it as the structure which has the above depth and the height from a floor surface is 1050 mm or less.

  According to the drum type washing machine of the present invention, since there is no risk of interference between the faucet and the housing, the overall height of the housing is made higher than before, and the position of the outer tub and the drum within the housing by that amount. To increase the position of the clothing inlet on the front surface of the housing. As a result, the user can easily put clothes in and out of the drum without taking an unreasonable posture such as bending the waist deeply or folding the knees, and the usability can be improved. .

  Hereinafter, a drum type washing and drying machine according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external side view of the drum type washing and drying machine according to the present embodiment with the door opened, FIG. 2 is an external perspective view of the drum type washing and drying machine of the present example, and FIG. 3 is a drum type of the present example. FIG. 4 is a schematic side sectional view of the drum-type washing / drying machine according to the present embodiment, and FIG. 5 is a housing of the drum-type washing / drying machine according to the present embodiment. It is a back perspective view of the state where a body was removed.

  The casing 1 forming the outer shape of the drum type washing and drying machine has a substantially box shape as a whole. As shown in FIGS. 1 and 2, the front surface 1a of the housing 1 is slightly curved from the upper part to the central part and is slightly inclined upward, and a substantially circular clothing input port 1b is provided there. The garment input port 1b is formed and opened and closed by a side-opening type door 2 through which the inside can be seen through. In addition, an operation panel 5 that is elongated to the left and right and on which various operation keys are arranged is provided on the upper portion of the front surface 1a, that is, on the clothes insertion opening 1b, and a drawer-type detergent container 6 is provided on the left side. Similarly, on the right side, a drawer-type dry filter container 7 is installed.

  The upper surface 1c of the housing 1 is a dropping portion 1d whose rear side is greatly depressed as compared with the front side. That is, the front side of the upper surface 1c is a substantially horizontal front flat part 1e, and the rear side is a substantially horizontal, strictly speaking, a rear flat part 1f that is gently inclined toward the rear, The rear edge of the front flat part 1e and the front edge of the rear flat part 1f are connected by an inclined part 1g that steeply inclines backward. Here, the rear flat portion 1f and the inclined portion 1g are the dropping portions 1d. The height from the floor surface to the front flat portion 1e, that is, the total height H1 of the drum type washing and drying machine is 1170 mm, and the height H2 from the floor surface to the forefront portion of the rear flat portion 1f is 1009 mm. The depth D from the rear surface of the housing 1 to the forefront portion of the rear flat portion 1f is 83 mm.

  The overall height of a conventional general drum-type washing and drying machine is about 1000 mm, whereas the overall height of the drum-type washing and drying machine of this embodiment is considerably higher than this for the reasons described later. Generally, the height of a water tap projecting on the wall surface of a washroom where a washing machine is disposed is 1100 to 1200 mm from the floor surface, so that the front flat portion 1e extends substantially horizontally to the rear surface. If there is, there is a possibility of interference with the water tap, but as described above, by providing the drop portion 1d on the rear side, it can be properly installed while avoiding interference with the water tap.

  Moreover, the water supply hose connection port 3 to which the other end of the water supply hose whose one end is connected to the water tap is connected to the rear left end of the front flat portion 1e, and one end is bath water in the bathtub to the right of the front flat portion 1e The bath water hose connection port 4 to which the other end of the bath water hose immersed in is connected. The water supply hose connection port 3 is formed by exposing a water inlet of a water supply valve 21 described later directly to the upper surface, and the bath water hose connection port 4 is formed by exposing the water inlet of the bath water pump 22 directly to the upper surface. Has been. Normally, the connection port of the water supply hose or the bath water hose is arranged near the rear edge of the upper surface or at the top of the rear surface. In this drum type washing and drying machine, the front flat portion is not the lower flat portion 1f. Since the water supply hose connection port 3 and the bath water hose connection port 4 are provided in 1e, the hose can be easily attached to and detached from the connection ports 3 and 4, and there is water leakage from the connection ports 3 and 4. In addition, the user can easily notice.

  Next, the internal structure of the drum type washing / drying machine will be described mainly with reference to FIG. An outer tub 10 having a substantially cylindrical outer peripheral surface is held inside the housing 1 by a damper 11 that supports the left and right lower sides and a spring (not shown) that pulls the upper part so that the outer tub 10 can swing appropriately. The front portion of the outer tub 10 is opened in a circular shape relative to the clothing input port 1b of the housing 1, and the opening 10a and the clothing input port 1b are connected by a seal member 12 made of an elastic material such as rubber. Has been.

  Inside the outer tub 10, a drum 13 having a substantially cylindrical shape for accommodating laundry is supported by a main shaft 14 that extends in the front-rear direction and is inclined forward. The front end surface of the drum 13 is greatly opened to be an opening 13a for putting clothes, and when the door 2 is opened, the opening 10a of the outer tub 10 and the opening 13a for putting clothes on the drum 13 are obliquely viewed from above. The inside of the drum 13 can be looked through. Here, the inclination angle θ of the central axis C of the drum 13, that is, the central axis of the main shaft 14 is set to about 15 ° with respect to the horizontal line, but this is an example, and the inclination angle θ is about 10 to 30 °, for example. Is set at an appropriate angle.

  The front end of the main shaft 14 is firmly fixed to the rear surface of the drum 13 and is rotatably supported by a bearing 16 of a bearing fixing member 15 attached to the rear surface portion of the outer tub 10. A rotor 17b of a motor 17 which is an outer rotor type DC brushless motor is attached to an end portion of the main shaft 14 protruding to the rear side of the outer tub 10, while a stator 17a of the motor 17 is fixed to the bearing fixing member 15. ing. The rotor 17b including the permanent magnet is disposed so as to surround the outer peripheral side of the stator 17a including the winding, and thus the motor 17 has a thin structure in the extending direction of the main shaft 14. When a drive current is supplied to the stator 17a from a control circuit (not shown), the rotor 17b rotates and the drum 13 is rotationally driven through the main shaft 14 at the same rotational speed as the rotor 17b.

  In the upper space in the housing 1, a water supply unit 20 including a water supply valve 21, a bath water pump 22 for supplying bath water, and a detergent charging unit 23 is disposed. The water inlet directed to the upper side of the water supply valve 21 is the water supply hose connection port 3, and the water inlet directed to the upper side of the bath water pump 22 is the bath water hose connection port 4. The detergent charging unit 23 that allows the detergent container 6 to be pulled out is disposed in front of the water supply valve 21, and the water supplied to the detergent charging unit 23 through the water supply valve 21 and the bath water pump 22 mainly passes through the interior of the detergent container 6. As described above, the water is supplied into the outer tub 10 from a water injection port 25 provided at the rear portion of the outer tub 10 through a water injection pipe 24 connected to the bottom of the detergent charging unit 23. The entire water supply unit 20 including the water supply valve 21 and the bath water pump 22 is disposed in the space below the front flat part 1e in front of the drop part 1d. Details thereof will be described later.

  As described above, the water supplied by the water supply unit 20 and stored in the outer tub 10 flows into the drum 13 through the water passage hole 13b. Further, water discharged from the laundry in the drum 13 during dehydration is scattered to the outer tub 10 side through the water passage hole 13b. A drain outlet 26 is provided behind the bottom of the outer tub 10, and the drain outlet 26 is connected to the inlet of the drain valve 27. When the drain valve 27 is opened, the water stored in the outer tub 10 is It is discharged out of the machine through the drain pipe 28.

  Further, this drum type washing machine has a component for achieving the function of drying the dehydrated laundry, which is not shown in FIG. 4, and an air discharge port is provided at the lower rear surface of the outer tub 10. The ventilation path connected to the air discharge port is connected to an air supply port provided on the front upper portion of the outer tub 10 through the rear, side and upper side of the outer tub 10. A drying filter that collects lint, dust, pollen, etc. mixed in the air, a fan that is driven by a fan motor, and a heater for drying are arranged in the middle of the ventilation path. The end of the cooling water hose is connected to the upright portion.

  Thus, during the drying operation, the wind generated by the fan is heated by the heater and then discharged from the air supply port and supplied into the outer tub 10. When the heated air passes through the inside of the drum 13, it exchanges heat with the laundry to remove moisture, and flows into the ventilation path through the air discharge port. Water flows continuously or intermittently through the cooling water hose through the upright portion of the ventilation path, and when heated air containing a large amount of water vapor contacts the cooling water, the water vapor is condensed and condensed. The condensed water flows down along the inner wall of the ventilation path together with the cooling water, flows into the outer tank 10 and is discharged from the drain port 26. The dry air from which water vapor is removed in the ventilation path circulates through the fan and returns to the heater. In addition, arrangement | positioning of the component for these drying is demonstrated later.

  As described above, the overall height of the drum type washing and drying machine of this embodiment is about 150 to 200 mm higher than that of a conventional general drum type washing and drying machine. Accordingly, the entire position of the outer tub 10 in which the drum 13 is housed is made higher by about 150 to 200 mm than before. Therefore, the clothes insertion opening 1b formed on the front surface 1a of the housing 1 is at a high position, and there is a burden of putting the laundry in and out of the drum 13 in an unreasonable posture where the user bends the waist or bends the knee. It is reduced. Further, when the door 2 is opened, the inner bottom portion of the drum 13 is easy to look over, which is useful for preventing the laundry from being left behind.

  As described above, since the outer tub 10 and the entire members around the outer tub 10 are arranged on the upper side in the housing 1, a space that did not exist conventionally is formed in the lower portion in the housing 1. Although not described in detail, in the drum type washing and drying machine of the present embodiment, the water storage tank 29 having a capacity of about 35 to 40 L and the water stored in the water storage tank 29 are supplied to the water supply unit 20. And a water purification device (not shown) for preventing germs from propagating in the stored water in the water storage tank 29. The relatively clean water after being used for the final rinse in the outer tub 10 during the washing operation is not discharged outside the apparatus, but is stored in the water storage tank 29 and held until the next washing operation. The stored water can be used at the time of the next washing operation. Thus, in the drum type washing and drying machine of the present embodiment, the space newly formed in the lower part of the outer tub 10 with the overall height of the housing 1 being increased is also effectively used.

  Then, the structure of the housing | casing in the drum type washing-drying machine of a present Example is demonstrated in detail with reference to FIGS. 6-8 in addition to FIGS. FIG. 6 is a perspective view showing a housing structure in the drum type washing and drying machine of the present embodiment, FIG. 7 is a rear perspective view in a state in which a top plate and a front decorative cover are removed, and FIG. 8 is from the state of FIG. Furthermore, it is a back perspective view of the state which removed the rear plate and the member of the outer tank upper part.

  The housing 1 is symmetrically inserted and fixed between a pair of left side plate 101 and right side plate 102, and upper front edges of the left and right side plates 101, 102, and a clothing input port 1b is formed at the center to attach the door 2. A front frame plate 103 that also serves as a frame, a front reinforcing plate 104 that is fixed between the front edge lower portions of the left and right side plates 101 and 102, and an upper front portion (front flat portion) of the left and right side plates 101 and 102 Between the upper front reinforcing plate 105 that is passed between and fixed between the upper front reinforcing plate 105 and the upper rear edges of the left and right side plates 101 and 102 (the position that corresponds to the inclined portion 1g).

Platform 114. Among these members, the top plate 110, the top decorative cover 111, the front decorative cover 112, the front lower cover 112, and the footrest 114 are made of synthetic resin with good workability, and other members other than these are stronger. Made of high metal.

  The upper portions of the left and right side plates 101, 102 have a shape that forms a front flat portion 1e, an inclined portion 1g, and a rear flat portion 1f, and the edges of the plate members are bent inward at substantially right angles to have a predetermined width. A flange 120 is formed. Further, the flange 120 is bent along the shape thereof, that is, an intermediate portion corresponding to the inclined portion 1g, and an obtuse angle at the front edge of the intermediate portion, and along the rear portion of the front flat portion 1e. Reinforcing metal fitting 121, which is an elongated plate-like member having a front edge portion that extends shortly and a rear edge portion that is bent at an obtuse angle at the rear edge of the intermediate portion and extends long along the rear flat portion 1f, is fixed with screws. The upper front reinforcing plate 105 and the upper rear reinforcing plate 106 are fixed to the flange 120 with screws, with the reinforcing metal fitting 121 interposed therebetween. The upper front reinforcing plate 105 and the upper rear reinforcing plate 106 are substantially U-shaped members in which both end portions of a plate-like member extending in the left-right direction are bent downward at a substantially right angle. The metal plates forming the side plates 101 and 102 are thin, and the flange 120 is not strong enough to be bent. However, the reinforcing plate 121 is used to reinforce the upper front reinforcing plate 105 and the upper rear reinforcing plate. The strength of the fixed portion 106 can be increased.

  Each of the upper front reinforcing plate 105 and the upper rear reinforcing plate 106 is a member that increases the strength of the upper surface 1c of the housing 1 and prevents the upper portions of the side surface plates 101 and 102 from opening in a direction away from each other. The strength of the bent portion corresponding to the inclined portion 1g is relatively weak at the upper edge portions of the side plates 101, 102, but the upper rear reinforcing plate 106 is attached to the inclined portion 1g to sufficiently increase the strength of the upper surface 1c. Can be increased.

  In a general use state, various articles are often placed on the upper surface 1c of the housing 1. Further, when stored in a warehouse or the like before sales, they are stacked in a state of being stored in a cardboard box or the like, so that a large load is easily applied to the upper surface 1c of the housing 1. On the other hand, in the drum type washer / dryer of this embodiment, the upper surface plate 110 is supported and supported by the reinforcing plates 105 and 106 firmly attached between the upper edge portions of the side surface plates 101 and 102. Even if the plate thickness of itself is thin, sufficient strength can be secured.

  Next, the arrangement of various members in the upper space in the housing 1 and in front of the depressed portion 1d will be described with reference to FIGS. 9 and 10 in addition to FIG. In this space, the above-described water supply unit 20 and a drying unit 40 in which members for drying are gathered are arranged. FIG. 9 is a top plan view showing a schematic arrangement of both units 20 and 40 in this space, and FIG. 10 is a top view of the entire water supply unit 20.

  The detergent container 6 has a shape in which a handle 62 having a curved shape according to the shape of the housing 1 is provided at the front portion of the tray 61 whose entire upper surface is open, and the whole is an integrally molded product of synthetic resin. It is. Although not shown in the drawing, the inside of the tray 61 includes a powder detergent container for storing powder detergent, a liquid detergent container for storing liquid detergent, and a soft finish container for storing soft finish. It is divided into three.
