Description

  The present invention relates to a washing / drying machine for drying after washing clothes and the like.

  As this type of washer / dryer, there are known a drum-type washer / dryer having a drum rotating around a horizontal axis or an inclined axis, and a washer / dryer having a bottomed cylindrical laundry dewatering tank rotating around a vertical axis. It has been. Hereinafter, a drum-type washing and drying machine that has been generally used as a washing and drying machine will be mainly described.

  As described above, the drum-type washing / drying machine has a configuration in which a cylindrical bowl-shaped drum is rotatably disposed inside the outer tub around a horizontal axis or an inclined axis, and the laundry is accommodated in the drum. Then, the laundry is beaten and washed by rotating it in an outer tub storing water, and after washing, the wet laundry is dried by sending heated air into the outer tub.

In order to perform such a drying operation, in the drum type laundry dryer, while heated air is sent into the outer tub, the moist air containing moisture exhaled from the wet laundry is taken out to the outside of the outer tub. It is provided with a circulation air path in which water vapor is condensed and liquefied through the heat exchanger to dry air, and the air is again heated by a heater and sent into the outer tub. By making the heat exchanger water-cooled, there is an advantage that the drying efficiency is not easily affected by the outside air temperature and hot air is not blown into the room.

  Since the washing and drying machine has to include components for washing as well as washing, the dimensions in the width direction and the depth direction tend to increase due to the structure. Especially in apartment houses such as condominiums, it is necessary to place a washing machine on a waterproof pan of a specified size, so the limit on the size of the outer box is quite strict. However, on the other hand, in recent years, there is an increasing demand for an increase in washing capacity, and in order to enlarge the outer tub while suppressing the size of the outer box, the space between the outer box and the outer tub inevitably tends to become narrower. . Therefore, for example, if the outer tub vibrates greatly during dehydration operation, the possibility that the outer tub and the member fixed to the outer tub will come into contact with the outer box increases, and even if such contact occurs, damage or failure of various members. Must be reduced as much as possible.

  The washing / drying machine according to the present invention is made in view of the above points, and the purpose of the washing / drying machine is that even if the outer tub vibrates greatly during operation, damage or failure occurs. An object of the present invention is to provide a washing / drying machine having a low reliability.

In order to solve the above problems, the present invention includes an outer box, an outer tub provided in the outer box and having a substantially cylindrical peripheral surface, and is rotatably provided in the outer tub. And a peripheral drum having a substantially cylindrical shape for accommodating laundry therein, a damper for supporting the lower portion of the outer tub, and a bearing fixed to the center of the end surface of the drum, on the end surface side of the outer tub The main rotor supported by the motor, an outer rotor type motor having a stator and a rotor attached to the tip of the main spindle, and air containing moisture from an exhaust outlet communicating with the outer tank is cooled to condense and liquefy water vapor. A heat exchanging unit, heating means for heating the air dehumidified by the heat exchanging unit, a blower chamber, a blower provided in the blower chamber, a blower motor in which the blower and a motor shaft are directly connected, and the outer Between the body of the tank and the outer box A horizontal air passage on the inlet side of the blower chamber through which the air passes, and extending substantially horizontally to the side of the blower chamber, with a dry air passage disposed in the gap and having an outlet end connected to the blower chamber. A blower chamber outlet side horizontal air passage bent outside the end face of the outer tub, and a horizontal air passage on the blower chamber outlet side communicating with the inside of the outer tub to heat the air heated by the heating means to the outer tub A hot air supply port provided on the end face of the outer tank,
The blower motor is provided in the outer tub on the side opposite to the surface of the outer box across the blower chamber, and the axis along the motor shaft is substantially orthogonal to the axis of the horizontal drum and is horizontal. Accordingly, the blower motor is disposed inside the horizontal air passage on the inlet side of the blower chamber constituting the drying air passage so as not to contact the outer box. It is characterized in that there.

  As an embodiment of the washing and drying machine of the present invention, the outer tub may have a substantially cylindrical peripheral surface, and the motor may be disposed close to the peripheral surface of the outer tub.

  In the washing and drying machine according to the present invention, when the outer tub vibrates greatly when the inner tub rotates at a high speed such as a dehydration operation, the drying air passage in a closer position may contact the outer box, The motor located inward of the drying air passage does not contact the outer box. Therefore, since an undesired impact is not applied to the blower motor, which is one of the parts that are likely to fail, it is possible to suppress the occurrence of the failure and to ensure high reliability.

  A detergent container 5 that can be pulled forward is provided on the left side of the upper lid 2, and an operation panel 6 is provided on the right side that extends in the front-rear direction. The operation panel 6 has various operation keys for setting the driving course, reservation time, etc., and lights according to these settings, notifies the progress of the washing process, or the remaining time for reservation and driving Various displays for displaying such as are appropriately distributed. Since almost the entire operation panel 6 is oriented obliquely upward, when the user looks down obliquely downward while standing in front of the present washing and drying machine, the surface of the operation panel 6 is perpendicular to the line of sight. Consideration is given that the display is close, the display is easy to see, and the operation keys are easy to press.

  Further, a water supply port 7 for connecting an external water supply hose and a bath water hose water supply port 8 for connecting a bath water hose are provided on the upper surface portion 1 a behind the upper lid 2. Although not shown, a bath water pump is installed directly below the bath water hose water supply port 8, and a water supply valve is installed directly below the water supply port 7. It is designed to supply inside.

  Next, based on FIGS. 4-7, the internal structure of this drum type washing-drying machine is demonstrated. Inside the outer box 1, the outer tub 10 whose peripheral surface is substantially cylindrical and whose both end surfaces are substantially closed is suspended from the upper left and right sides with the end faces facing the left and right side surfaces of the outer box 1. The two springs 11 to be supported and the damper 12 to support the lower part of the outer tub 10 in the front-rear direction are held so as to be moderately swingable. In this outer tub 10, a horizontal drum C, which has a substantially cylindrical shape and whose both end surfaces are substantially closed, extends in the left-right direction as an inner tub for storing laundry therein. It is provided so as to be rotatable around the center. A number of water passage holes 14 are formed in the drum 13.

  The main shaft 15 fixed to the center of the left end surface of the drum 13 is supported by a first bearing 16 held by a first bearing case 17 fixed to the left end surface of the outer tub 10. On the other hand, the auxiliary shaft 18 fixed to the center of the right end surface of the drum 13 is supported by a second bearing 19 held by a second bearing case 20 fixed to the right end surface of the outer tub 10. The horizontal axis C is formed by the main shaft 15 and the auxiliary shaft 18. The main shaft 15 and the auxiliary shaft 18 and the first and second bearing cases 17 and 20 are sealed with oil seals 21, respectively. Even when water is stored in the outer tub 10, the first and second bearings 16. , 19 escapes flooding.

  A rotor 222 of a motor 22, which is an outer rotor type DC brushless motor, is attached to the tip of the main shaft 15 that protrudes laterally from the left end surface of the outer tub 10, while the first bearing case 17 that also serves as a motor base is attached to the first bearing case 17. A stator 221 of the motor 22 is fixed. When a drive current is supplied to the stator 221 from a control circuit (not shown), the rotor 222 is rotated thereby, and the drum 13 is rotationally driven through the main shaft 15 at the same rotational speed as the rotor 222.

  Between the outside of the outer tub 10 around the second bearing case 19 and the side surface of the outer box 1 (not shown in FIGS. 5 and 7) on the opposite side of the motor 22 across the drum 13, during the drying operation A drying air passage for circulatingly supplying heated air to the inside of the outer tub 10 is arranged. This point will be described later in detail.

  Immediately below the laundry inlet 3 closed by the upper lid 2 is located the upper part of the peripheral surface of the cylindrical body of the outer tub 10, and there is an axis extending substantially parallel to the horizontal axis C. An outer tank opening 101 that is opened and closed by a single outer tank door 102 that opens to the rear side is provided at the center. A drum opening 131 that is opened and closed by a drum door 132 formed of two door bodies having a double door opening structure in the front-rear direction around an axis extending substantially parallel to the horizontal axis C is provided on the peripheral surface of the drum 13. Is provided.

  The drum 13 rotates in the outer tub 10, but at least when the user puts laundry into and out of the drum 13, the drum opening 131 is positioned at a position where the drum opening 131 coincides with the outer tub opening 101 in the radial direction. Need to stop. Therefore, the drum position fixing device 23 is provided on the left end surface of the outer tub 10, and the stop position is set by meshing between the engaging convex portion protruding from the device 23 and the engaging concave portion formed in the rotor 222 of the motor 22. It is configured to be determined. Thereby, when putting in and out the laundry, the user can look into the inside of the drum 13 from obliquely forward and upward by opening the upper lid 2, the outer tub door 102, and the drum door 132.

  A drain outlet 24 is provided at the bottom of the outer tub 10, and the drain outlet 24 is connected to an external drain groove through a drain hose (not shown) via a drain valve 25. When water is stored in the outer tub 10, the drain valve 25 is closed. When the drain valve 25 is opened, the water in the outer tub 10 is discharged to the outside of the machine through the drain port 24 and the drain hose. .

  Next, the structure of the drying air path, which is a feature of the drum type washing and drying machine, will be described in detail with reference to FIGS.

  8 is an external front view of the body member 10a which is one member constituting the outer tub 10, FIG. 9 is a left side view of the body member 10a, and FIG. 10 is a dehumidifying pipe which is one member constituting the drying air passage. FIG. 11 is a front external view of the dehumidifying pipe 30, FIG. 12 and FIG. 13 are cross-sectional views taken along lines AA 'and BB' in FIG. 10, and FIG. It is sectional drawing in the DD 'arrow line in FIG. In addition, in the said drawing which drawn the trunk | drum member 10a and the dehumidification pipe 30, the surface which becomes a front in the completion state as a drum type washing-drying machine is defined as the front.

  As shown in FIGS. 8 and 9, the body member 10 a of the outer tub 10 is an integrally molded product of synthetic resin in which the left end surface is substantially closed and the right end surface is open, and is formed at a substantially central lower portion in the horizontal axis C direction. An exhaust outlet 10b communicating with the inside of the outer tub 10 is provided, and a cylindrical exhaust pipe 10c extending from the exhaust outlet 10b in the horizontal axis C direction to the right end surface is integrally formed. This exhaust outlet 10b becomes an outlet from which wet air is discharged from the outer tub 10 during the drying operation, and the exhaust pipe line 10c becomes a part of the drying air path.

  An end face member 10d that substantially closes the end face is attached to the open end face on the right side of the body member 10a. A circular opening is provided at a position on the end face member 10d that corresponds to the open end face of the exhaust pipe 10c. 10e is formed. A dehumidifying pipe 30 constituting a part of the drying air passage is fixed to the end face member 10d as described later.

  As shown in FIGS. 10 and 11, the dehumidifying pipe 30 has a flat opening that has an opening 31 that opens in a substantially circular shape toward the side at the lower end and forms a side vertical air passage 32 that extends in a substantially vertical direction. A cylindrical body (corresponding to a vertical duct) and a rear horizontal air duct 33 (corresponding to a transverse duct) extending to bend obliquely upward from substantially horizontal in communication with the upper part of the side vertical air duct 32 are formed. And a flat cylindrical body to be integrated. A water pipe connection port 34 is provided at a position lower than the connection portion between the side vertical air passage 32 and the rear horizontal air passage 33, and a cooling water pipe led from a water supply valve is connected to the water pipe connection port 34, and is fed through the cooling water pipe. The incoming cooling water (tap water) flows into the side vertical air passage 32. As a result, the side vertical air passage 32 functions as a heat exchanging unit for cooling the air flow including the moist air to condense and liquefy the water vapor.

  As shown in FIGS. 5 to 7, the dehumidifying pipe 30 is attached so that its opening 31 fits into the opening 10 e of the outer tub 10, and the side vertical air passage 32 is formed between the right end surface of the outer tub 10 and the outer box. The rear horizontal air passage 33 is disposed in a space between the rear side of the trunk portion of the outer tub 10 and the rear surface portion 1d of the outer box 1.

  The fitting state between the opening 31 of the dehumidifying pipe 30 and the opening 10e of the end face member 10d of the outer tub 10 is as shown in FIG. That is, a double cylindrical rib 10e1 protrudes around a circular opening 10e formed in the end face member 10d, and the cylinder of the opening 31 of the dehumidifying pipe 30 is provided in the groove of the rib 10e1. The edge of the shape is fitted. An O-ring 10e2 is fitted on the outer peripheral side of the cylindrical edge of the opening 31, and this O-ring 10e2 is pressed against the inner surface of the rib 10e1 to ensure airtightness and watertightness. With such a configuration, the O-ring 10e2 can be fitted on the outer peripheral side of the cylindrical edge portion of the opening 31 of the dehumidifying pipe 30 at the time of assembly and pushed into the end face member 10d of the outer tub 10, so that the operation is easy. Moreover, since the length at the fitting portion between the two is short, there is an advantage that a large cross-sectional area of the dry air passage can be secured without unnecessarily taking up space for fitting.

  The outlet end of the rear horizontal air passage 33 is open toward the front, and is connected to the rear of the blower chamber 40 in which the blower 41 is installed. In front of the blower chamber 40, that is, on the opposite side of the rear surface portion 1d of the outer box 1 across the blower chamber 40 and on the upper rear side of the outer tub 10, an axis F along the motor shaft is substantially orthogonal to the horizontal axis C and A blower motor 42 is disposed so as to extend horizontally, and the motor shaft of the blower motor 42 and the blower 41 are directly connected. As described above, by providing the blower motor 42 not in the rear surface 1d side of the outer box 1 but inside the drying air passage, the blower motor 42 contacts the outer box 1 even when the outer tub 10 vibrates greatly during a dehydrating operation or the like. There is nothing. Therefore, an undesired impact can be avoided from being applied to the blower motor 42, and failure of the blower motor 42 can be reduced.

  On the right side of the blower chamber 40, it extends substantially horizontally, bends forward at a substantially right angle outside the right end surface of the outer tub 10, and further bends horizontally at a right angle above the auxiliary shaft 18. An air passage 43 is connected. The outlet end of the side horizontal air passage 43 is provided so as to cover the opening 20 a formed in the second bearing case 20. In this side horizontal air passage 43, a heater 44 made of a sheathed wire is disposed as a heating means, and heats the air passing through the air passage 43. An opening 10f is provided in a portion of the end face member 10d of the outer tub 10 that is covered with the second bearing case 20, and the side is interposed between the opening 20a of the second bearing case 20 and the opening 10f of the outer tub 10. The horizontal horizontal air passage 43 and the inside of the outer tub 10 communicate with each other. Therefore, this opening 10 f functions as a hot air supply port into the outer tub 10.

  In addition, since the inside of the side horizontal air passage 43 becomes high temperature and particularly high heat resistance is required, the members constituting the side horizontal air passage 43 are made of metal. On the other hand, the temperature of the air flowing through the side vertical air passage 32 and the rear horizontal air passage 33 is lowered because the air passes through the outer tub 10, so the members constituting the dehumidifying pipe 30 place importance on cost. For example, it is made of a blow molded product. The blower chamber 40 is configured by a combination of a metal member on the blower motor 42 side and a synthetic resin molded product on the rear horizontal air passage 33 side. This is because the portion facing the blower motor 42 is close to the heating means, so that heat resistance is required, and high rigidity is required to hold the blower motor 42 that is a heavy object.

  When the blower 41 is rotationally driven by the blower motor 42 in the dry air passage configured as described above, the blower 41 discharges air sucked from the rear side toward the side. Therefore, an air flow from the blower chamber 40 toward the side horizontal air passage 43 is formed, and the high-temperature air flow (hot air) heated by the heater 44 while passing through the side horizontal air passage 43 is It is sent into the outer tub 10 through an opening 10f which is a hot air supply port. A plurality of vent holes 13 b are formed radially around the auxiliary shaft 18 on the right end surface of the drum 13, and high-temperature air mainly flows into the drum 13 from the vent holes 13 b.

  When wet laundry is accommodated in the drum 13, the high-temperature air that has entered the drum 13 passes through the gap between the laundry and the gap between the fibers of the laundry, and at that time deprives the laundry of moisture. The air sufficiently containing the moisture is mainly discharged to the outside of the drum 13 through the water passage hole 14 in the body portion of the drum 13, and then to the exhaust outlet 10 b through the gap between the drum 13 and the outer tub 10. Head. Further, such a flow of air in the circumferential direction is also promoted by the rotation of the drum 13. Thus, since the high-temperature air flows so as to wrap the drum 13 from the surroundings, the drum 13 is maintained at a high temperature, and high drying efficiency can be achieved.

  The air containing a large amount of moist air taken out from the exhaust outlet 10b to the outside of the outer tub 10 reaches the opening 31 which is the inlet of the side vertical air passage 32 through the exhaust pipe 10c extending horizontally. Ascend in the vertical air passage 32. As described above, the cooling water is supplied into the side vertical air passage 32, and the cooling water flows in a direction opposite to the traveling direction of the air flow, so that the moist air is exchanged by heat exchange with the cooling water. It is cooled rapidly. As a result, the water vapor contained in the air condenses to become water, condenses on the inner wall surface of the dehumidifying pipe 30, and flows down along it. Therefore, the air is dehumidified as it passes through the heat exchanging section in the side vertical air passage 32, becomes dry air, returns to the blower chamber 40 through the rear horizontal air passage 33. Then, it is sent again to the side horizontal air passage 43 by the blower 41 and reheated by the heater 44.

  Water condensing on the inner wall surface of the side vertical air passage 32 flows into the exhaust pipe 10c through the opening 10e, opposite to the air flow, along with the cooling water, and along the gentle slope of the bottom of the exhaust pipe 10c. 10 flows into. Finally, it is discharged from the drain port 24 to the outside of the machine. Further, a part of the water flowing down in the side vertical air passage 32 also flows out from the drainage hole formed in the gap when the end surface member 10d is attached to the body member 10a of the outer tub 10.

  As described above, during the drying operation, air circulates in the drying air passage including the outer tub 10, and moisture is taken away from the laundry in the course of the circulation, and the moisture is removed from the air by cooling with the cooling water. The Therefore, one way to increase the drying efficiency is to increase the dehumidification efficiency in the side vertical air passage 32. However, increasing the flow rate of the cooling water in order to enhance the cooling effect is not desirable from the viewpoint of saving water, so it is important to obtain a high dehumidifying effect while reducing the amount of cooling water used as much as possible. Therefore, in the drum type washer / dryer of the present embodiment, the configuration of the heat exchange unit for dehumidification is as follows.

  That is, as shown in FIGS. 10 and 15, in the side vertical air passage 32, the inner wall surface directly below the water pipe connection port 34 forms an inclined wall 301 and bulges inward at the lower end of the inclined wall 301. The upper bulging portion 302 is provided. Therefore, the water discharged from the water pipe connection port 34 into the side vertical air passage 32 flows down along the inclination of the inclined wall 301 as shown by the thick arrow in FIG. Overcoming the tip and falling while dispersing.

  Moreover, the throttle part which made the cross-sectional area of a pipe line small is formed in the lower part of the side part vertical air path 32 as an aspect of a convex part by making the inner wall face bulge inward of a pipe line. That is, as shown in FIG. 12, FIG. 13 and FIG. 16, in this throttling part, a part of both inner wall surfaces facing the transverse direction in which the horizontal cross section of the pipe is elongated is bulged inwardly of the pipe and opened. The first and second bulging portions 305 and 306 are formed in which the first bulging portion 304 having a narrowed portion is formed, and both inner wall surfaces facing in the longitudinal direction bulge inward to narrow the opening. Is formed. The width of the opening in the short direction is not uniform, and has a wide portion (for example, a portion of width L2 shown in FIG. 13) and a narrow portion (for example, a portion of width L1 shown in FIG. 13). . In such an opening shape, the rising air flow is easy to pass in the wide part, so the flow rate per unit time is large, while the flow rate is relatively small, while in the narrow part, the air flow is relatively small. Since the flow is difficult, the flow rate is relatively large. For this reason, the flow velocity of the air flow is not uniform in the horizontal cross section immediately above the throttle portion, thereby generating a complicated turbulent flow. Furthermore, as shown in FIG. 16, the first bulging portion 304 is provided not to be horizontal in the longitudinal direction but to be inclined downward in the direction of the wide opening portion at an angle θ.

  With the above configuration, as shown by the thick arrows in FIG. 16, a part of the water that has been dispersed and dropped as described above hits the first to third bulging portions 304, 305, 306 and rebounds, and is further smaller. Spatters as water droplets. At this time, since the first bulging portion 304 has an inclination as described above, the water hitting the upper surface of the first bulging portion 304 rebounds diagonally upward rather than directly above. In addition, although small water droplets are blown up by the rising air flow, the water droplets are swung up and swirled due to the non-uniform and complicated flow velocity of the air flow.

  Of course, in reality, there are those in which water droplets collide with each other or change the direction by hitting the inner wall surface of the side vertical air passage 32 in the middle of dropping, so the trajectory of the water droplet becomes more complicated, and the pipe line above the throttle portion. Inside, a kind of cooling layer is formed in which water droplets of various sizes are scattered. In this cooling layer, most of the introduced water stays for a relatively long time, and since it is a small water droplet, the effective surface area is large. Therefore, even with a relatively small amount of water, heat exchange with air can be performed efficiently, and moist air can be efficiently cooled to promote condensation and liquefaction of water vapor. As a result, drying efficiency can be improved while saving water, and drying time can be shortened.

  On the other hand, for the air flow rising up the side vertical air passage 32, the throttle portion becomes a resistance, so that dust such as lint that rises in the air flow stays below the throttle portion. Such trash is caught by water flowing down from above and discharged together with the water. Therefore, it is possible to prevent the lint that soars from the laundry during the drying operation from adhering to the laundry again.

  Further, in the upper bulging portion 302 and the third bulging portion 306, as shown in FIG. 13, a fixed piece portion 307 is formed on the outside of the pipe wall, and the fixed piece portion 307 has a screw hole. Is perforated. When the dehumidifying pipe 30 is fixed to the end face member 10d of the outer tub 10, the fixed piece 307 is brought into contact with the boss 10d1 projecting from the end face member 10d and screwed with the screw 10d2 from the outside. As shown in FIG. 10, since the fixed piece 307 does not protrude outward, the probability of occurrence of a defect when the member constituting the dehumidifying pipe 30 is blow-molded can be kept very low. Moreover, since the parison used for blow molding does not need to be large, cost reduction can be achieved in this respect.

  By the way, in this drum type dry washing machine, the dehumidifying pipe 30 is configured as described above, so that a position for forming a handle portion used mainly during transportation is secured on the rear surface portion 1d of the outer box 1. FIG. 17 is a rear external view of the drum-type drying washing machine. As depicted in FIG. 17, at the position close to the rear surface portion 1 d of the outer box 1, the rear horizontal air passage 33 of the dehumidifying pipe 30 has a shape bent obliquely upward as it goes from the side to the center. . Then, one side of the handle portion 1 f that is recessed forward from the rear surface portion 1 d of the outer case 1 is provided on the side of the blower chamber 40 above the horizontal portion of the rear horizontal air passage 33. The handle portion 1f is provided as a pair of left and right, and the present washing and drying machine can be lifted by inserting a fingertip into the recess of the handle portion 1f.

  That is, in this drum type washing / drying machine, the rear horizontal air passage 33 along the rear surface portion 1d of the outer box 1 is bent so that the handle portion 1f and the rear horizontal air passage 33 are in the same horizontal plane in the front-rear direction. Therefore, the handle portion 1f and the dehumidifying pipe 30 do not interfere with each other, and the handle portion 1f can be arranged at an appropriate position when lifting the present washing machine.

  It should be noted that the above embodiment is merely an example of the present invention, and it is obvious that changes and modifications can be made as appropriate within the scope of the present invention. Moreover, although the said Example is an example which applied this invention to the drum type washing / drying machine, this invention is not only a drum type washing / drying machine but centering on the axis | shaft slightly inclined from the vertical axis | shaft as mentioned above. Of course, the present invention can also be applied to a washing and drying machine including a rotatable bottomed cylindrical laundry dewatering tub.
