Description

  The present invention relates to a washing and drying machine for washing and drying clothes.

  Conventionally, what uses an electric heater as a heat source for drying of a washing dryer is known. Recently, a washing / drying machine using a heat pump (refrigeration cycle) has appeared because it can reduce power consumption as compared with a conventional electric heater type.

  In the heat pump type washing dryer, clothes drying air is dehumidified from the washing tub through the evaporator of the heat pump, heated in the condenser and returned to the washing tub again to circulate in a closed loop. However, in a heat pump embodied by a refrigeration cycle including a condenser and an evaporator, the condensation heat quantity Qc of the condenser is a value obtained by adding the heat quantity Qi of the compressor input to the evaporation heat quantity Qe of the evaporator (Qc = Qe + Qi). Therefore, as the circulation in the closed loop is repeated, the temperature of the drying air gradually increases. Then, the condensation temperature and evaporation temperature of the refrigeration cycle also increase. As a result, the heat pump cannot be stably operated.

  One approach to solving these problems and ensuring stable operation without reducing the drying performance of the heat pump is to either exhaust a portion of the high-humidity circulating air that is returned from the washing tub to the heat pump, or There is known a method of exhausting heat by substituting (see, for example, Patent Document 1).

JP-A-2004-215543

  However, in the washing and drying machine equipped with the heat pump according to Patent Document 1, waste heat exhausted from the compressor, the driving motor of the washing tub and the fan, and the outer tub and duct during the drying operation is wasted. There was room for improvement from the viewpoint of reducing power consumption.

  In addition, in the conventional technology using a heat pump, a part of the high-humidity circulating air returned from the washing tub to the heat pump is exhausted as it is, or is replaced with outside air to exhaust heat and a washing dryer is installed. There is also a problem of deteriorating the surrounding environment such as a bathroom.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a highly efficient and environment-friendly washing and drying machine.

In order to achieve the above-mentioned object, the present invention provides an outer tub in which a drying chamber becomes a drying chamber when drying, an inner tub that is rotatably provided in the outer tub and stores laundry, and a drying device. a duct through which air circulates, a heating device to dry the laundry is provided in the duct, the cooling means, and in laundry dryer and a blowing means, within the housing, magnetic work generating the magnetocaloric effect a magnetic refrigerating device provided by perforated materials and magnetic field generator for applying a magnetic field to the magnetic working material, in the housing, exerts a magnetic field on the magnetic working material and the magnetic working material to generate the magnetocaloric effect A magnetic refrigeration apparatus provided with a magnetic field generator, and moving at least one of the magnetic working material and the magnetic field generator to a relatively high temperature at one end of the magnetic refrigeration apparatus A high temperature heat medium is generated and a low temperature heat medium having a relatively low temperature compared to the high temperature is generated at the other end, and the heating unit is configured to generate heat of the high temperature heat medium sent from the one end of the magnetic refrigeration apparatus.

  First, how the present invention was made will be described. In order to realize a highly efficient and environmentally friendly washing and drying machine, the present inventors have applied a magnetic field to a magnetic substance on a completely different principle from the conventional refrigeration technology applying gas compression / expansion. We focused on the magnetocaloric effect producing high and low temperatures. Some magnetic materials (hereinafter referred to as magnetic working substances) have a reversible phenomenon in which the temperature rises (dissipates heat) when an external magnetic field (magnetic field) is applied, and the temperature decreases (endothermic) when the magnetic field is removed. Is done. This is the magnetocaloric effect.

  The principle of the magnetocaloric effect is as follows. That is, the entropy of the electron system changes due to the difference in the degree of freedom of the spin system inside the magnetic working material between the state where the magnetic working material is applied with the magnetic field and the state where the magnetic working material is removed. With this entropy change, energy is instantly exchanged between the electron system and the lattice system inside the magnetic working material. This changes the temperature of the magnetic working material (the degree of lattice vibration). This is the principle of the magnetocaloric effect.

A device that performs heat exchange on an object using such a magnetocaloric effect is hereinafter referred to as a magnetic refrigeration apparatus. In particular, a device that uses the magnetocaloric effect in a temperature band near room temperature is called a room temperature magnetic refrigeration apparatus. The present inventors paid attention to a magnetic refrigeration apparatus that produces such a magnetocaloric effect, and examined various problems that occur when this magnetic refrigeration apparatus is incorporated in a washing dryer. Through these studies, the present inventors finally completed the present invention.
Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings.

Fig. 3 is a side sectional view showing the internal structure, and Fig. 3 is a rear front view showing the internal structure by removing the back cover of the drum type washing and drying machine 1 shown in Fig. 1. FIG. 4 is a rear front view showing the internal structure of the washing / drying machine according to the modification of the first embodiment.

  As shown in FIG. 1, the housing 2 of the drum-type washing / drying machine 1 is provided with a door 3 for putting clothes (laundry) 4 in and out on the front side and a back cover 5 on the back side. As shown in FIG. 2, a cylindrical outer tub 6 that does not rotate (fixed) is provided inside the housing 2. The outer tub 6 is levitated and supported with respect to the installation surface (floor surface) of the housing 2 by a plurality of suspensions 7 provided at the lower portion of the housing 2. A cylindrical rotary drum (corresponding to an “inner tank”) 8 is rotatably provided inside the outer tank 6. The rotating drum 8 has a shape similar to that of the outer tub 6. The size of the rotating drum 8 is set smaller than that of the outer tub 6. The outer tub 6 and the rotating drum 8 are open on the front side corresponding to the opening of the door 3. Thereby, the door 3 can be opened and the clothes 4 can be put into the rotary drum 8. A fluid balancer 9 is provided on the outer periphery of the opening of the rotary drum 8 to reduce vibration due to unbalance of the garment 4 during dehydration.

  A plurality of lifters 10 for scooping up the garment 4 are provided inside the rotating drum 8. The rotary drum 8 is directly connected to a drum drive motor 11 provided on the rear side of the drum. By driving the drum drive motor 11, the rotary drum 8 is rotatable around its rotation axis.

  A packing 12 made of an elastic material such as silicone rubber is attached to the opening of the outer tub 6. The packing 12 plays a role of maintaining watertightness between the inside of the outer tub 6 and the door 3. This prevents water leakage during washing, rinsing, and dehydration.

  As shown in FIG. 2, the rotating drum 8 has a large number of small holes 38 for centrifugal dehydration and ventilation on its peripheral side wall. A drain port 13 opened in the bottom wall of the outer tub 6 is connected to a drain hose 14. As shown in FIG. 1, an operation unit 15 that is used when selecting a washing or drying mode or the like is provided on the front upper portion of the housing 2. In addition, the code | symbol 16 in FIG. 2 represents the circulating air flow (warm air) used for drying of clothing. As shown in FIGS. 3 and 4, the circulating air flow 16 is blown by a fan 35 corresponding to a blowing means.

  The fan 35 may be a turbo fan or a sirocco fan that can generate a high pressure, an axial fan, a propeller fan, or the like. The installation place of the fan 35 is not particularly limited. The fan 35 may be provided anywhere in the middle of the circulating air flow 16 (for example, a drum inlet duct 25 or a drum outlet duct 24 described later).

  As shown in FIG. 2, a magnetic refrigeration apparatus 17 that is a heat source of the present invention is provided at the lower part of the housing 2. As will be described later, the magnetic refrigeration apparatus 17 includes a magnetic working material 19 and a magnetic field generator 18 that applies a magnetic field to the magnetic working material 19 as main components. In the example of FIGS. 2 and 3, the magnetic refrigeration apparatus 17 is provided on the bottom surface portion 1 a of the housing 2. Specifically, the magnetic refrigeration apparatus 17 is provided in a cylindrical space 49 provided in the bottom surface portion 1a of the housing 2 as shown in FIG. 2 or FIG. The disk-shaped or donut-shaped cylindrical space 49 has a shape in which the area of the plane as the bottom surface is large and the distance between the peripheral side surfaces in the axial direction is short.

  The merit of installing the magnetic refrigeration apparatus 17 on the bottom surface portion 1a of the housing 2 is that when the magnetic refrigeration apparatus 17 is heavy, the center of gravity can be kept low, the stability of the main body of the washing and drying machine 1 is good, and When a part of the magnetic refrigeration apparatus 17 is rotationally moved (moved), the vibration of the main body of the washing / drying machine 1 can be easily suppressed.

  However, the magnetic refrigeration apparatus 17 is provided in a cylindrical space (disk-shaped or donut-shaped space) 49 provided in the back surface portion 1b of the housing 2 as shown in FIG. 4 instead of the bottom surface portion 1a of the housing 2. May be. The merit of providing the magnetic refrigeration apparatus 17 on the back surface portion 1b of the housing 2 includes sharing of the drum drive motor 11 and a magnetic field generator drive motor 39 described later. In short, the magnetic working material 19 and the magnetic field generator 18 which are the main components of the magnetic refrigeration apparatus 17 may be provided anywhere in the housing 2 as long as the storage space is allowed.

  As shown in FIG. 3, the magnetic refrigeration apparatus 17 is used when driving the driving means 20 such as a pump for moving the heat medium into the magnetic working material 19, the cooling means 21 for dehumidifying and cooling damp air, and drying the clothes 4. A heating means 22 serving as a heating source for the air flow 16 is additionally provided. The same applies to the magnetic refrigeration apparatus 17 shown in FIG.

  As shown in FIG. 3, the circulating air flow 16 used when the clothes 4 are dried becomes a high-temperature and low-humidity air flow 16 a by the heating means 22, and is supplied from the drum inlet 26 into the rotary drum 8 through the drum inlet duct 25. . In the rotary drum 8, the high-temperature and low-humidity air flow 16 a takes moisture from the clothing 4 and becomes a high-humidity air flow 16 b and is sent from the drum outlet 23 to the drum outlet duct 24.

  Then, the high-humidity air flow 16 b is cooled and dehumidified by the cooling means 21, becomes a low-temperature high-humidity air flow 16 c, and is sent to the heating means 22 again. The air flow 16 used for drying repeats the above circulation, thereby removing moisture from the clothes 4 and drying the clothes.

  The feature of the first embodiment is that the outer tub 6, the rotating drum (inner tub) 8, the magnetic refrigeration apparatus 17 having the magnetic working material 19 and the magnetic field generator 18, the heating means 22, the cooling means 21, and the ventilation of a fan or the like. All the components including the means 35 are mounted in the housing 2 of the single washing / drying machine 1.

  Next, the structure of the magnetic refrigeration apparatus 17 mounted in the drum type washing / drying machine 1 according to Embodiment 1 will be described with reference to the drawings. FIG. 5 is a perspective view showing an outline of the magnetic refrigeration apparatus 17 mounted on the washing / drying machine 1 according to the first embodiment. FIG. 6 is a perspective view showing an outline of the magnetic refrigeration apparatus 17 mounted on the washing / drying machine 1 according to the modification of the first embodiment.

  As shown in FIG. 5, the magnetic refrigeration apparatus 17 mounted on the drum-type washing and drying machine 1 according to the first embodiment has a cylindrical space (disk shape) with a large area of a plane as a bottom surface and a short side surface in an axial direction. Alternatively, a donut-shaped space) 49 is formed. A plurality (specifically, eight) of the tubular flow paths 28 containing the magnetic working substance 19 are laid radially so as to extend along the radial direction of the cylindrical space 49. In order to hold the both ends of the plurality of tubular channels 28 at a predetermined interval, tubular channel holders 54a are provided at the ends on the outer peripheral side at the ends in the radial direction of the cylindrical space 49, and at the ends on the inner periphery. Tubular flow path holders 54b are respectively provided.

  Moreover, in the modification of Embodiment 1 shown in FIG. 6, the magnetic refrigeration apparatus 17 has a cylindrical space (cylindrical or tubular space) 49 in which the area of the plane that is the bottom surface is narrow and the side surface is long in the axial direction with respect to the bottom surface. It is configured. In this case, a plurality of tubular flow paths 28 containing the magnetic working substance 19 are laid so as to be long in the axial direction (longitudinal direction) of the cylindrical space 49. In order to hold both ends of the plurality of tubular channels 28 at a predetermined interval, a tubular channel holder 54a is provided at the upper end of the tubular space 49 at the axial ends thereof, and a tubular stream is provided at the lower end thereof. A path holder 54b is provided.

  Here, the cylindrical space 49 referred to in the present invention may be a thin disk-shaped space as shown in FIG. 5 or an elongated cylindrical space as shown in FIG. The shape of the plane need not be limited to a circular shape, and may be a quadrangle such as a square, a hexagon, an octagon, or the like. Moreover, it may replace with the cyclic | annular form (hollow shape) which has space in the center, and may be columnar shape (solid shape) like a cylinder or a prism.

  5 and 6, reference numerals 30a and 30b represent permanent magnets. The material of the permanent magnets 30a, 30b (sometimes collectively referred to as “permanent magnet 30”) is preferably composed of either neodymium or ferrite. However, other materials may be used, and may be determined according to necessary magnetic force, mounting dimensions, and the like. Further, in one magnetic refrigeration apparatus 17, permanent magnets 30 made of several kinds of materials may be used together.

  Below, description is advanced along the magnetic refrigeration apparatus 17 mounted in the drum type washing-drying machine 1 which concerns on Embodiment 1 shown in FIG. However, even if it is the magnetic refrigeration apparatus 17 mounted in the drum type washing-drying machine 1 which concerns on the modification of Embodiment 1 shown in FIG. 6, the basic idea is the same.

  FIG. 7 is a cross-sectional view of the magnetic refrigeration apparatus 17 housed in the disc-shaped cylindrical space 49 shown in FIG. 5 as seen from the direction of arrow A in FIG. FIG. 8 is a partial perspective view of the magnetic refrigeration apparatus 17 of FIG. 7 as viewed from the direction of arrow B of FIG. 7, and is positioned so that one tubular flow path 28 is sandwiched between a pair of permanent magnets 30a and 30b. The state of being cut out is shown partially.

  FIG. 7 shows an example in which eight tubular channels 28 (28a to 28h) containing the magnetic working substance 19 are installed. In addition, the number of the tubular flow paths 28 containing the magnetic working substance 19 may be smaller than this, or conversely. However, as shown in FIG. 9, a relatively high-temperature high-temperature heat medium 27b generated at the high-temperature end (corresponding to “one end”) of the magnetic refrigeration apparatus 17 that is a feature of the present invention, and the low-temperature end (“the other end”). In the case of using both of the low-temperature heat mediums 27a that are relatively low in temperature compared to the high temperature generated at the end "corresponding to the end", the number of the tubular flow paths 28 is preferably set to an even number. In particular, when almost the same amount of heat is required for both the high-temperature heat medium 27b and the low-temperature heat medium 27a, the number of the tubular channels 28 in which the high-temperature heat medium 27b and the low-temperature heat medium 27a are respectively generated is halved. It should be set to an even number.

  As shown in FIG. 8, the magnetic field generator 18 includes a pair of permanent magnets 30 a and 30 b provided on the upper surface (the upper surface of the flat surface of the disk-shaped cylindrical space 49) and the lower surface (the lower surface of the flat surface portion). The U-shaped magnet holder 29 that holds the pair of permanent magnets 30a and 30b at a predetermined interval, the magnetic field generator drive motor 39 that rotates the magnet holder 29, and the magnet holder 29 and the magnetic field generator drive The connecting shaft 40 is connected to the motor 39. Reference numeral 53 in FIG. 8 denotes a magnetic field (magnetic field) generated by the permanent magnets 30a and 30b, and the direction of the magnetic field is indicated by a wavy line.

  Here, as shown in FIG. 7, four magnetic field generators 18 are provided at equal intervals in the direction around the axis, and are integrally rotated by a single drive motor 39. The code | symbol 34 shown in FIG. 7 is a magnetic field generator moving direction. The number of magnetic field generators 18 is not limited to four. The number of the magnetic field generators 18 can be set to an arbitrary number such as 6 or 8, for example.

  As described above, the magnetic working substance 19 is divided and filled into [N = 8: even number] tubular flow paths 28, and the magnetic field generator 18 is half the number N of the tubular flow paths 28, that is, [N / 2. = 4]. In the first embodiment, as described above, a relationship of “the number of magnetic field generators [N / 2] with respect to the number of tubular flow paths [N: even number]” is desirable.

  Next, based on the drum-type washing and drying machine 1 according to the first embodiment described with reference to FIGS. 1 to 4 and the magnetic refrigeration apparatus 17 described with reference to FIGS. The operation principle and usage of the magnetocaloric effect applied to the drum type washer / dryer 1 according to the first embodiment will be described in detail. FIG. 9 is a diagram in which the part C in FIG. 7 is cut out. Here we consider this as a set of systems. That is, in FIG. 7, four sets of systems are provided. FIG. 10 is a perspective view of a tubular flow channel having joints on both end faces. FIG. 11 is a perspective view of a tubular channel having a joint perpendicular to the side edge.

  The magnetic working substance 19 is equally stored (packed) in each of the eight tubular channels 28. The shape of the magnetic working substance 19 is preferably spherical (round) for the purpose of reducing the passage resistance (pressure loss) of the heat medium 27 flowing in the tubular flow path 28 as much as possible. However, the present invention is not limited to this, and the particle shape may be a square shape (cube or rectangular parallelepiped) or a star shape, or a combination of various shapes. Furthermore, for example, even in the same spherical shape, several types of grains having different diameters may be mixed and stored. In this case, the small magnetic working material 19 enters the gaps between the large magnetic working material 19, and the storage density (mounting density) of the magnetic working material 19 in the tubular flow path 28 can be improved. The shape of the magnetic working material 19 may be a thin and long plate (on a strip) or the like.

  The magnetic working material 19 is preferably made of gadolinium (Gd) that can be used near room temperature and its alloys, or a ferromagnetic material such as MnAs that is a ferromagnetic compound metal. However, the present invention need not be limited to these materials. What is necessary is just to select the material suitably according to the temperature specification of the low temperature end 17a and the high temperature end 17b requested | required with a washing dryer. A plurality of materials may be mixed depending on the situation.

  The tubular channel 28 is preferably made of a material that has low thermal conductivity and is not affected by the magnet. As a specific material of the tubular flow path 28, for example, a resin such as polycarbonate, Teflon (registered trademark), silicone, or acrylic is preferable. The tubular channel 28 may be made of the same material as the magnetic working substance 19.

  The extraction of the heat medium (water in this embodiment) from the tubular flow path 28 containing the magnetic working substance 19 in the tubular flow path holder 54 to the heating means 22 and the cooling means 21 is conceptually shown in FIG. The joints 48 may be provided on both end faces of the tubular channel 28 and connected to the water channel (hose etc.) 31 as they are. In addition, as conceptually shown in FIG. 11, joints 48 may be provided substantially perpendicularly to the side end portions of the tubular flow path 28 and connected to the water flow path (hose or the like) 31. Of course, a combination of the joints 48 by both methods may be used.

  In FIG. 9, the tubular flow path 28 a is contained in the magnetic field generator 18 a (see FIG. 8) sandwiched between the pair of permanent magnets 30 a and 30 b, and is in a direction orthogonal to the axial direction of the tubular flow path 28 a ( A magnetic field is applied in a direction perpendicular to the paper surface. On the other hand, the tubular channel 28b is detached from the magnetic field generator 18a, and the magnetic field is removed. Therefore, in this case, due to the magnetocaloric effect described later, the magnetic working material 19 in the tubular channel 28a is heated (temperature rise), and the magnetic working material 19 in the tubular channel 28b is lowered (temperature lowered). Become.

  As shown in FIG. 9, the flow path through which the water 27 as the heat medium flows is configured as follows. First, the water channel 31 a is connected to the joint 48 b of the tubular channel 28 a, and the other end of the water channel 31 a is connected to the heating means 22. The other end of the heating means 22 is connected to the joint 48d of the tubular channel 28b via the pump 20 and the water channel 31b, and the joint 48a at the other end of the tubular channel 28b is connected to the water channel 31c. The other end of the water flow path 31c is connected to the cooling means 21, and the other end of the cooling means 21 is connected to the water flow path 31d. The water flow path 31d is connected to the joint 48c of the tubular flow path 28a, so that the flow of the heat medium 27 is completed.

  The water (heat medium) 27 used here may be pure water or soft water (water whose hardness component is zero or extremely small), or may be tap water or well water depending on the use situation. Further, it may be mixed water mixed with antifreeze or the like so that it can be used even in cold districts, or water containing antiseptic or rust preventive agent to prevent corrosion or rust. Further, for the purpose of rust prevention or the like, a rust preventive agent or the like may be applied, coated or plated on the surface of the magnetic working material 19 itself.

  The pump 20 does not always move (circulate) the heat medium (water) 27 in one direction, but reciprocates in the water flow path 31 as will be described later, and is constituted by a reciprocating pump, a plunger pump, or the like. .

  In the case of the example of FIG. 9, the tubular flow path 28a is located in the magnetic field by the pair of permanent magnets 30a and 30b, whereas the tubular flow path 28b protrudes from the magnetic field by the pair of permanent magnets 30a and 30b. Yes. In the magnetocaloric effect in this case, the magnetic working material 19 accommodated in the tubular flow path 28a generates heat by the action of the magnetic field, and the magnetic working material 19 accommodated in the tubular flow path 28b desorbs heat by being out of the magnetic field. To do.

  At this time, when the heat medium (water) 27 in the water channel 31 is caused to flow in the directions of solid arrows 32 and 33 (both in the same direction) by the operation of the pump 20, the low temperature end 48a of the tubular channel 28b has a low temperature. The heat medium 27a (cold water) is generated at the high temperature end 48b of the tubular flow path 28a, and the heat medium 27b (warm water) is generated and sent to the cooling means 21 and the heating means 22, respectively. . Here, reference numeral 32 in FIG. 9 indicates the moving direction of warm water (high temperature heat medium) heated in the tubular flow path 28a by the solid line arrow, and reference numeral 33 in FIG. 9 indicates the tubular flow path 28b. The moving direction of the cold water (low-temperature heat medium) lowered in temperature is indicated by the solid line arrow.

  Then, in the cooling means 21 provided in or behind the drum outlet duct 24, the low-temperature heat medium 27a sent from the low-temperature end 48a of the tubular flow path 28b by the water flow path 31c is the high-temperature output from the rotary drum 8. After exchanging heat with the high-humidity air stream 16b (see FIG. 3), heat is taken from the air stream 16b, and the cooling means 21 is exited.

  Here, the heat exchanger 41 that constitutes the cooling means 21 and the heating means 22 described later needs to efficiently exchange heat between water (liquid) 27 and air (gas) 16 that are heat media. Therefore, for example, a cross fin tube type heat exchanger may be used. FIG. 12 is a perspective view of a cross-fin-tube heat exchanger in which air flows in the short direction of the fins. The cross fin tube type heat exchanger 41 includes a plurality of (many) thin fins 42, a plurality of tubes 43 penetrating therethrough, and a U-shaped bend 44 connecting the tubes 43 in a U-shape. Etc. In the cross fin tube type heat exchanger 41, the surface of the fin 42 is in contact with the air flow 16, the inner surface of the tube 43 is in contact with the water 27, and heat is exchanged between them.

  The fins 42 are made of aluminum having a good thermal conductivity or an alloy thereof. Similarly, the tube 43 and the U-shaped bend 44 are preferably made of aluminum, copper, or an alloy thereof having good thermal conductivity.

  The cooling means 21 and the heating means 22 are not limited to the cross-fin-tube-type heat exchanger 41, but are heat exchangers composed of other types such as a more compact corrugated fin-type heat exchanger. May be.

  In the cross fin tube type heat exchanger 41 shown in FIG. 12, the air flow 16 flows in the short direction of the fin 42, and the cross-sectional area between the fins through which the air flow 16 flows can be secured widely. There is an advantage that the ventilation resistance (pressure loss) of the air flow 16 flowing between them can be reduced.

  Now, by the heat exchange in the cooling means 21, on the air flow 16 side, the high-temperature and high-humidity air flow 16b sent between the narrow fins of the heat exchanger 41 exchanges heat with the low-temperature heat medium 27a. Heat is taken away by 27a and cooled, and moisture in the air stream 16 is condensed. Thereafter, the low-temperature, high-humidity air flow 16c (see FIG. 3) dehumidified and cooled by moisture condensation exits the heat exchanger 41, which is the cooling means 21.

  On the other hand, in the heating means 22 provided in or in front of the drum inlet duct 25, the high temperature heat medium 27b sent from the high temperature end 48b of the tubular flow path 28a by the water flow path 31a is produced by the cooling means 21. Heat exchange with the low-temperature and high-humidity air stream 16c that has been sent, and heat is released to the air stream 16c to lower the temperature. On the other hand, the low-temperature and high-humidity air flow 16c sent between the fins of the heat exchanger that is the heating means 22 exchanges heat with the high-temperature heat medium 27b, takes heat away from the heat medium 27b, and increases the temperature. The air flow 16a exits the heating means 22.

  FIG. 13 is a developed view of the side surface portion of FIG. 7 (expanded by extending the C portion in the circumferential direction), and the tubular flow channels 28c and 28d following the tubular flow channels 28a and 28b shown in FIG. Shows up. As shown in FIG. 13, one magnetic field generator 18a is at the position of the tubular flow path 28a, and the other magnetic field generator 18b is at the position of the tubular flow path 28c, and applies a magnetic field to the tubular flow paths 28a and 28c, respectively. ing. Conversely, there is no magnetic field generator 18 at the positions of the tubular channels 28b, 28d, and the magnetic field is removed. In FIG. 13, the inside of the tubular flow path 28 is shaded to indicate a state in which a magnetic field is applied (a state in which the directions of electron spins responsible for magnetism of the magnetic working material 19 are aligned). A blank inside indicates a state in which no magnetic field is applied (a state in which the direction of the electron spin responsible for the magnetism of the magnetic working material 19 is random).

  Subsequently, when the magnetic field generator 18 is slowly rotated in the in-plane direction by the magnetic field generator drive motor 39 (34 is the moving direction of the magnetic field generator), the state (positional relationship) shown in FIG. 14 is obtained. FIG. 14 is a developed view of the side surface of the disk in which the magnetic field generator of FIG. 13 is advanced by one step. This shows a state where the magnetic field generator has moved from the solid line position 18 to the broken line position 18a 'in FIG. Then, this time, the magnetic field generator 18a is at the position of the tubular flow path 28b, and the magnetic field generator 18b is at the position of the tubular flow path 28d, and a magnetic field is applied to the tubular flow paths 28b and 28d (heat generation), respectively. There is no magnetic field generator 18 at the positions of the tubular flow paths 28a, 28c, and the magnetic field is removed (cooled state).

  At this time, in FIG. 9, when the water supply direction is switched by the pump 20 and the flow of the water 27 in the tubular flow path 28 and the water flow path 31 is reversed (in the direction of the broken line arrow), this time, the high temperature end of the tubular flow path 28 b The high temperature heat medium 27d (warm water) is generated in 48d, and the low temperature heat medium 27c (cold water) is generated in the low temperature end 48c of the tubular flow path 28a. The water 27c and 27d are the cooling means 21 and the heating means 22, respectively. Sent to.

  Then, in the cooling means 21, the low-temperature heat medium 27 c sent from the low-temperature end 48 c of the tubular flow path 28 a by the water flow path 31 d exchanges heat with the high-temperature and high-humidity air flow 16 b that has come out of the rotating drum 8. After taking the heat from 16b and raising the temperature, the cooling means 21 is exited. On the contrary, due to heat exchange in the cooling means 21, on the air flow 16 side, the high-temperature and high-humidity air stream 16b sent between the narrow fins of the heat exchanger 41 that is the cooling means 21 is heated with the low-temperature heat medium 27c. The low temperature heat medium 27c is deprived of heat and cooled, and the moisture in the air stream 16 is condensed. Thereafter, the low-temperature and high-humidity air stream 16 c dehumidified and cooled by moisture condensation exits the heat exchanger 41 that is the cooling means 21.

  On the other hand, in the heating means 22, the high-temperature heat medium 27 d sent from the high-temperature end 48 d of the tubular flow path 28 b through the water flow path 31 b and the low-temperature and high-humidity air stream 16 c sent from the cooling means 21 and the heat After exchanging, heat is released to the air flow 16c and the temperature is lowered, the heating means 22 is exited. On the other hand, the low-temperature and high-humidity air flow 16c sent between the fins of the heat exchanger, which is the heating means 22, exchanges heat with the high-temperature heat medium 27d, deprives the heat from the heat medium 27d, and rises in temperature. And exits the heating means 22.

  As described above, the four magnetic field generators 18a to 18d are slowly rotated in the in-plane direction by one magnetic field generator drive motor 39 (34 is the magnetic field generator moving direction), so that The temperature of the tubular flow path 28 (magnetic working material 19) located at the place where the magnetic field is applied rises, and high temperature heat media 27b and 27d (warm water) are generated at the high temperature end of the tubular flow path 18.

  On the other hand, the temperature of the tubular flow path 28 (magnetic working material 19) located at a place away from the magnetic field generator 18 is lowered, and low temperature heat media 27a and 27c (cold water) are generated at the low temperature end of the tubular flow path 18. .

  The heat is guided to the cooling means 21 and the heating means 22 through the heat medium 27 by the reciprocating movement of the pump 20 every predetermined time, respectively, so that both the dehumidifying cooling and heating of the air flow 16 used for drying are performed. Can be done continuously.

  FIG. 15 is an overall system configuration diagram of the drum type washing and drying machine 1 according to the first embodiment using the magnetocaloric effect. In this system configuration example, four sets of a system composed of two tubular channels 28 and one magnetic field generator 18 are arranged. For example, the tubular channels 28a and 28b, the pump 20a, the cooling means 21a, and the heating means 22a constitute a set of systems.

  Hereinafter, three sets of systems are configured by combining similar components, and the four cooling means 21a to 21d are arranged in series in the drum outlet duct 24, and the four heating means 22a to 22d are arranged in series in the drum inlet duct 25. Has been deployed. Of course, the arrangement of the cooling means 21 and the heating means 22 may be arranged in parallel instead of in series, or may be an arrangement according to a combination thereof.

  By configuring as shown in FIG. 15, the high-temperature and high-humidity air flow 16b that has come out of the drum 8 is provided in the drum outlet duct 24 (including the rear part of the drum outlet duct), with four cooling means 21d, 21c, 21b, By passing in the order of 21a, it is gradually cooled and dehumidified, resulting in a low-temperature and high-humidity air flow 16c and reaching the drum inlet duct 25. In the drum inlet duct 25 (including the front part of the drum inlet duct), the low-temperature and high-humidity air flow 16c is gradually heated by passing through the four heating means 22a, 22b, 22c, and 22d in this order, The air flow 16a is reached to the rotating drum 8.

  In the rotary drum 8, the high-temperature and low-humidity air flow 16a evaporates moisture from the garment 4 to take away moisture from the garment, and the high-temperature and high-humidity air flow 16b is sent to the drum outlet duct 24 and used for drying. The air flow 16 repeats the above circulation to dry the clothes.

  Here, although it is an example, the desired values of the temperature and relative humidity at the initial stage of drying of the air flow 16 are roughly as follows. The high-temperature and low-humidity air flow 16a entering the rotating drum 8 has a temperature of 40 to 70 ° C. and a relative humidity of 0 to 20%, and the high-temperature and high-humidity air flow 16b exiting the rotating drum 8 is 30 to 60 ° C. and 80 to 100%. The low-temperature and high-humidity air flow 16c is about 10 to 30 ° C. and about 80 to 100%. Therefore, it is most desirable that the magnetic working material 19 of the present invention that exhibits the magnetocaloric effect has performance corresponding to the above-mentioned various values. Needless to say, the values of the temperature and the relative humidity change depending on the surrounding environment (temperature and humidity of the outside air), the capacity and type of clothes to be dried, the pattern of the drying operation, or restrictions on the magnetic working material 19 to be used. .

  Here, the movement of the heat medium may be a continuous slow reciprocating movement, but when the heat medium in the lowest temperature zone of the low-temperature heat medium 27a, 27c reaches the cooling means 21, and the high-temperature heat medium 27b, When the heat medium in the highest temperature zone of 27d reaches the heating means 22, the drive of the pump 20 is temporarily stopped, and a stationary period (time) of the heat medium in the heat exchanger 41 is provided. Further, more efficient heat exchange may be achieved. In this case as well, the air flow 16 continues to flow.

  Note that, depending on the specifications (shape, size, etc.) of the magnetic refrigeration apparatus 17, the cooling means 21, the heating means 22, etc., as an example, the rotation of the magnetic field generator drive motor 39 is a low speed operation of about 10 seconds per rotation. But you can.

  Further, when the magnetic refrigeration apparatus 17 is installed on the main body rear surface portion 1 b of the drum type washing and drying machine 1 as shown in FIG. 4, the magnetic field generator drive motor 39 may be shared with the drum drive motor 11. . That is, the drum drive motor 11 may be used for rotating the magnetic field generator 18. In this case, it is assumed that the rotational speed of the rotating drum 8 and the rotational speed of the magnetic field generator 18 are different. However, this difference in rotational speed may be absorbed by taking measures such as changing the pulley diameter by combining the transmission gears or driving the belt.

  Next, the size comparison between the tubular flow path 28 containing the magnetic working substance 19 and the pair of permanent magnets 30a and 30b attached to the magnetic field generator 18 will be described. FIG. 16 shows an example of a tubular channel 28 having a circular cross section according to the first embodiment. FIG. 17 shows an example of a rectangular tubular channel 45 (the channel cross section may be either square or rectangular) according to a modification of the first embodiment. FIG. 18 shows an example of an oval tubular channel 46 (which may be an ellipse or a rectangular section with a rounded square) according to a modification of the first embodiment. In any example, the relationship between the lateral flow path width Wd of the tubular flow paths 28, 45 and 46 and the magnet width Wm of the permanent magnet 30 is the same magnetic field process (from the start to the end of excitation of the magnetic working material 19). In order to secure the time required, the relationship “Wd <Wm: the magnet width Wm is larger than the flow path width Wd” is desirable at least. Furthermore, it can be said that “Wm = 2 Wd to 3 Wd: the magnet width Wm is about 2 to 3 times the flow path width Wd” is more desirable for efficient heat exchange.

  In the first embodiment described above, as shown in FIG. 9, the tubular flow path 18 that is accommodated in one magnetic field generator 18 is a single straight pipe without a bent portion, but the present invention is not limited to this example. . FIG. 19 is an explanatory diagram for explaining the extraction of the magnetocaloric effect in the tubular flow path folded back into a 180-degree U shape. As shown in FIG. 19, the tubular flow path 18 that fits in one magnetic field generator 18 may be a U-shaped tubular flow path 47 having a hairpin portion that is folded back into a 180-degree U shape. In this case, a pair of joints 48 (for example, 48a and 48b) at both ends of the U-shaped tubular channel 47 are adjacent to each other. For this reason, there are cases where the water flow path 31 can be easily connected to the cooling means 21 and the heating means 22, for example.

  In the first embodiment, as shown in FIG. 15, one pump 20 a to 20 d is provided for each set of systems including two tubular flow paths 28 and one magnetic field generator 18. Therefore, although an example in which four pumps are provided for convenience has been described, the present invention is not limited to this example. FIG. 20 is an overall system configuration diagram of the washing / drying machine according to the modification of the first embodiment of the present invention in which the heat medium is sent by one pump. In place of the first embodiment in which one pump 20a to 20d is provided for each set of systems, as shown in FIG. 20, the role of four pumps divided into one large pump 20 is assigned. The water flow path 31 fed from the pump 20 may be divided into four. In this case, it is desirable that the specification conditions of the four systems (pressure loss during passage of water through the tubular flow paths 28, 47, the cooling means 21, the heating means 22, etc.) are complete or substantially the same.

  In the first embodiment, the magnetic field generator 18 is rotationally moved by the magnetic field generator drive motor 39. However, originally, the relative positional relationship between the tubular flow paths 28 and 47 and the magnetic field generator 18 is described. However, it is sufficient that the magnetic field generator 18 is fixed and the tubular flow paths 28 and 47 may be moved.

  In the first embodiment, a liquid, particularly easily usable water, is used as the heat medium 27, but a gas, particularly air, may be used as the heat medium 27. In this case, the heat exchanger used for the cooling means 21 and the heating means 22 may be a cross fin tube type heat exchanger 41 (fin tube heat exchanger) as shown in FIG. ) Has a lower heat transferability than liquid (water), so it is desirable to increase the heat exchange area on the heat medium 27 side. For example, adoption of a fin plate heat exchanger, a plate heat exchanger, etc. can be considered. When a liquid such as water is used as the heat medium 27, it is necessary to take countermeasures such as leakage, but when a gas such as air is used as the heat medium 27, it is advantageous in that leakage is allowed.

  In the first embodiment described above, the magnetic refrigeration apparatus 17 in which the magnetic field generator 18 shown in FIG. 7 is rotationally moved 34 in one direction has been mainly described. However, some other embodiments will be described below. To do.

  FIG. 21 shows an example of a magnetic refrigeration apparatus 17 in which the magnetic field generator 18 reciprocates 34 a certain distance in the circumferential direction by the rotation of the central magnetic field generator drive motor 39. The basic configuration is the same as in FIG. In FIG. 7, the magnetic field generator 18 (18a, 18b, 18c, 18d) is slowly rotated in one direction by the central magnetic field generator drive motor 39, whereas in FIG. ing.

  As shown in FIG. 21, for example, the magnetic field generator 18a reciprocates 34 between the tubular flow paths 28a and 28b, and the magnetic field generator 18c reciprocates 34 between the tubular flow paths 28e and 28f. The same applies to the other magnetic field generators 18b and 18d. The effect in this case (extraction of magnetocaloric effect, etc.) is the same as that described above (FIG. 7 and the like).

  FIG. 22 shows an example of the magnetic refrigeration apparatus 17 in which the magnetic field generator 18 includes an electromagnet 51. That is, in FIG. 8, the permanent magnets 30a and 30b are replaced with electromagnets 51a and 51b, and one magnetic field generator 18 (electromagnet 51) is arranged in one tubular flow path 28 as shown in FIG. It will be. In FIG. 22, reference numeral 52 denotes a control device that controls ON and OFF of the electromagnet 51 according to the situation, and reference numeral 50 denotes a signal line that connects the control device 52 and the electromagnet 51.

  As shown in FIG. 22, for example, the magnetic field generator 18a is disposed in the tubular flow path 28a, the magnetic field generator 18b is disposed in the lateral tubular flow path 28b, and when the electromagnet 51 of the magnetic field generator 18a is ON. The electromagnet 51 of the magnetic field generator 18b is turned off, the high-temperature heat medium 27 is generated in the tubular flow path 28a, and the low-temperature heat medium 27 is generated in the tubular flow path 28b.

  Conversely, when the electromagnet 51 of the magnetic field generator 18a is OFF, as shown in FIG. 22, the electromagnet 51 of the magnetic field generator 18b is in the ON state, and the low-temperature heat medium 27 is generated in the tubular flow path 28a. A high-temperature heat medium 27 is generated in the path 28b.

  The operations of the other magnetic field generators 18 and the tubular channel 28 are the same. Further, in the above description, it is considered that a pair (generation of the high-temperature heat medium 27 and the low-temperature heat medium 27) is adjacent to each other (tubular flow paths 28a and 28b), but the combination is free. The tubular channels 28e to 28h may be configured to generate the low temperature heat medium 27 when the high temperature heat medium 27 is generated by 28d.

  In the modification of the first embodiment shown in FIG. 22, the magnetic field generator drive motor 39 as in the examples shown in FIG. 7 and FIG. 21 is not necessary, but each magnetic field generator 18 is turned ON / OFF by electricity. Since the electromagnet 51 is required, it is only necessary to consider which one to select by comparing the mountability and power consumption of both systems as a whole.

  FIG. 23 is a cross-sectional view showing a magnetic refrigeration apparatus including a tubular channel having a curvature along a magnetic field. As shown in FIG. 23, for example, a tubular flow path 28a having a curvature is formed along a magnetic field (magnetic field) 53 of a pair of permanent magnets 30a and 30b. Again, the magnetic field generator 18 equipped with a pair of permanent magnets 30a, 30b is rotated in one direction 34 by the central magnetic field generator drive motor 39.

  FIG. 24 shows another embodiment of the (cross fin tube type) heat exchanger 41 of FIG. In FIG. 12, the air flow 16 flows along the short direction of the fin 42, whereas in FIG. 24, the air flow 16 flows along the longitudinal direction of the fin 42. In FIG. 24, since many tubes 43 can be arranged in the direction in which the air flow 16 flows, if the temperature of the heat medium 27 flowing in the tubes 43 is changed, the temperature change width of the air flow 16 flowing between the fins 42 is changed. Can be increased. On the other hand, the method shown in FIG. 12 has an advantage that the airflow resistance of the air flow 16 flowing between the fins 42 can be reduced.

  Furthermore, as a method of reducing wasteful heat exhausted from the washing / drying room to the room and reducing the power consumption, the inside of the washing / drying machine main body as heat loss from the drum drive motor 11 and the fan 35 motor of the drum type washing / drying machine 1 The heat (heat generation) released to each of the motors may be collected by air inside the main body flowing around each motor, and the warmed main body internal air may be guided to the air flow 16.

  According to the first embodiment, an outer tub 6 whose inside becomes a drying chamber when drying is provided in the housing 2, and a rotary drum (inner tub) 8 that is rotatably provided in the outer tub 6 and accommodates laundry. A washing / drying device including ducts 24 and 25 through which drying air circulates, heating means 22 provided in the ducts 24 and 25 for drying laundry, cooling means 21, and a fan (air blowing means) 35. 1 includes a cylindrical space 49 provided in the housing 2, a magnetic working material 19 that generates a magnetocaloric effect, and a magnetic field generator 18 that applies a magnetic field to the magnetic working material 19. And a magnetic refrigeration apparatus 17 provided in the apparatus. By moving at least one of the magnetic working material 19 and the magnetic field generator 18, a high temperature heat medium is generated at the high temperature end of the magnetic refrigeration apparatus 17 and a low temperature heat medium is generated at the low temperature end. The heating means 22 dissipates the heat of the heat medium sent from the high temperature end of the magnetic refrigeration apparatus 17, and the cooling means 21 absorbs the heat of the heat medium sent from the low temperature end of the magnetic refrigeration apparatus 17, The laundry is dried by sequentially circulating the drying air in the order of the heating means 22, the outer tub 6, the cooling means 21, and the heating means 22. As a result, the power consumption can be reduced as compared with an electric heater type washing and drying machine, and high humidity or high temperature air is not discharged into the washing and drying machine 1 or indoors, and the surrounding environment is not deteriorated. It is possible to reduce the amount of power consumption by reducing waste heat exhausted from 1 to the room.

  In addition, a coefficient of performance COP (heat output / electrical input) of 1 or more is obtained as compared with the conventional electric heater type washing and drying machine, and the energy saving performance is good (the power consumption can be reduced). Since both the heating heat quantity Qc by the heating means obtained at both ends of the magnetic refrigeration apparatus and the cooling heat quantity Qe by the cooling means can be used simultaneously for both heating and cooling (dehumidification) of the circulating air (warm air), Don't waste your heat.

  In addition, compared to conventional heat pump type washing and drying machines, the environmental load is very small because no fluorocarbon refrigerant such as refrigerant R134a having a global warming potential (GWP) of about 1300 is used. Further, since the heating heat quantity Qc by the heating means and the cooling heat quantity Qe by the cooling means are substantially the same heat quantity, it is not necessary to exhaust or exhaust a part of the circulating air used for drying around the washing dryer. Furthermore, because of the nature of the system, a compressor that rotates at high speed is not used, so that low vibration and low noise can be realized.
