Description

  The present invention relates to a dryer and a washing dryer provided with means for drying clothes.

  Conventionally, an electric heater has been used as a drying heat source for washing dryers and clothes dryers. However, recently, a washing dryer using a heat pump (refrigeration cycle) has been released as it can reduce power consumption compared to the electric heater type. I came.

  The heat pump type washing and drying machine circulates air for drying clothes from a washing tub through a heat pump evaporator, and is circulated in a closed loop which is heated by a condenser and returned to the washing tub again.

  However, in the heat pump type, the amount of heat of condensation Qc of the condenser exceeds the amount of heat of vaporization Qe of the evaporator by an amount corresponding to the input of the compressor Qi constituting the refrigeration cycle (Qc = Qe + Qi). Will gradually rise. As a result, the condensation temperature and evaporation temperature of the refrigeration cycle continue to rise, and the heat pump cannot be operated stably.

  Therefore, as a method for stable operation without deteriorating the drying performance by the heat pump, there is a method in which 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 (specialty). No. 2004-215943).

  On the other hand, in the field of refrigeration and air conditioning, the technology that is expected to be able to reduce power consumption compared to the electric heater type in the future is “Magnetic Calorie Effect” (for example, the Japan Society of Mechanical Engineers Vol.112 No.1082 p.50 (2009.1 )), And there are examples of use in air conditioning systems for railway vehicles (Japanese Patent Laid-Open No. 2006-056274) and air conditioners (Japanese Patent Laid-Open No. 3-70944).

Journal of the Japan Society of Mechanical Engineers Vol.112 No.1082 p.50 (2009.1), Research and development of non-fluorocarbon refrigeration system using magnetocaloric effect

  The conventional technology using a heat pump in a washing and drying machine as in Patent Document 1 has a merit that power consumption can be reduced as compared with the electric heater type, but a part of high-humidity circulating air returned from the washing tub to the heat pump. Since it is necessary to exhaust heat by substituting with the outside air, there is a demerit that the surrounding environment such as a washroom in which the washing / drying machine is installed is deteriorated.

  In addition, the conventional technology using a heat pump does not effectively use the exhaust heat from the compressor, the washing tub or fan drive motor, the outer tub or the duct during the drying operation, and the drying efficiency is not necessarily good. is not.

  Next, the “magnetocaloric effect” described in Non-Patent Document 1 will be described.

  Certain types of 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. This is called the “magnetoresistive effect (for details, see Non-Patent Document 1 etc.)”, and the one using this is called a magnetic refrigeration apparatus, a magnetic refrigerator, a magnetic refrigeration system, etc. Called magnetic refrigeration equipment). Those that are used in the temperature range near room temperature are called room temperature magnetic refrigeration equipment.

  In conventional techniques such as the railway vehicle air conditioning system and the air conditioner described in Patent Document 2 and Patent Document 3 using this magnetocaloric effect, either the low temperature end or the high temperature end of the magnetic refrigeration apparatus is refrigerated.・ Used only for cooling (low temperature end use) or heating (high temperature end use). For this reason, the heat at the other end is discarded as it is, and the two heat sources of the low temperature end and the high temperature end are not effectively used.

  In addition, there is no example using the magnetocaloric effect in a washing dryer or a clothes dryer for drying clothes.

  Therefore, the present invention can reduce the power consumption compared with the conventional electric heater type dryer or washing dryer which has been used as the main force of the prior art, and discharges high-humidity or high-temperature air into the laundry dryer or indoors, thereby surrounding environment. It is another object of the present invention to provide a dryer and a laundry dryer that can reduce power consumption by reducing waste heat exhausted from the laundry dryer into the room.

  In order to achieve the above object, the present invention provides an outer tub whose inside becomes a drying chamber at the time of drying, an inner tub that is rotatably disposed in the outer tub and accommodates laundry, and a magnet that generates a magnetocaloric effect. A working material, a magnetic field generator for applying a magnetic field to the magnetic working material, a means for sending a heat medium, a heating means for radiating the heat of the heat medium sent from a high temperature end of the magnetic field generator, and a low temperature of the magnetic field generator The heating medium sent from the end is provided with a magnetic refrigeration device composed of a cooling means for absorbing ambient heat, and when the laundry is dried, the air is supplied to the heating means, the outer tub, the cooling means, and the heating means. It is characterized by circulating in this order.

  According to the present invention, since the magnetic refrigeration apparatus using the magnetocaloric effect is mounted on the washing / drying machine, the following characteristics are obtained.

  Compared to an electric heater type washing and drying machine, a coefficient of performance COP (heat output / electric input) of 1 or more is obtained, and energy saving performance is good (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 the current heat pump type washing and drying machine, 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, since a high-speed rotating compressor is not used, low vibration and low noise can be achieved.

It is a back elevation view which shows a structure.

  A door 3 through which clothes (laundry) 4 is put in and out is provided on the front surface of the outer frame 2 of the drum-type washing and drying machine 1, and a back cover 5 is provided on the back surface. A cylindrical outer tub 6 that does not rotate is provided inside the outer frame 2. The outer tub 6 is supported by a plurality of lower suspensions 7. The rotating drum (inner tub) 8 inside the outer tub 6 has clothes 4 put in by opening the door 3, and the outer periphery of the opening of the rotating drum 8 vibrates due to unbalance of the garments 4 during dehydration. Is provided with a fluid balancer 9.

  In addition, a plurality of lifters 10 are provided on the inner side of the rotating drum 8 to scoop up the clothes 4. The rotary drum 8 is directly connected to a drive motor 11 provided at the rear of the drum.

  A rubber packing 12 made of an elastic body is attached to the front opening of the outer tub 6. The packing 12 serves to maintain the water tightness between the outer tub 6 and the door 3. This prevents water leakage during washing, rinsing and dehydration.

  The rotating drum 8 has a large number of small holes 38 for centrifugal dehydration and ventilation on the side wall. A drain port 13 opened in the bottom wall of the outer tub 6 is connected to a drain hose 14. Reference numeral 15 denotes an operation unit, 16 denotes a circulating air flow (warm air) used for drying clothes, and the circulating air flow 16 is blown by a fan 35 which is 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. Further, the installation location of the fan 35 is not particularly limited as long as it is in the middle of the circulating air flow 16 (for example, a drum inlet duct 25 or a drum outlet duct 24 described later).

  Reference numeral 17 denotes a magnetic refrigeration apparatus which is a heat source of the present invention, and main components are a magnetic field generator 18 for applying a magnetic field to a magnetic working material 19 (member composed of a magnetic working material) described later, and the inside of the magnetic working material 19 These include a pump (driving means) 20 for moving the heat medium, a cooling means 21 for dehumidifying and cooling damp air, and a heating means 22 serving as a heating source for the air 16 used when drying the clothes 4.

  In the present embodiment, the magnetic refrigeration apparatus 17 is installed at the lower rear of the main body of the washing / drying machine 1, but it may be installed at the lower part of the main body of the washing / drying machine 1 (lower front or lower center). You may install in. Moreover, installation may straddle a main body lower part and a back surface.

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

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

  Here, the feature of the present invention is that the outer tub 6, the inner tub 8, the magnetic refrigeration apparatus 17, the heating means 22, the cooling means 21, and the heating means 22 and the cooling means 21 respectively exchange heat with the heat medium 27. All elements including the air 16 are mounted in the single washing / drying machine main body 1.

  Next, based on the drum-type washing / drying machine of the present invention described in FIGS. 1 to 3, the details of the washing / drying machine using the magnetocaloric effect of the present invention will be described with reference to FIGS. .

  FIG. 4 is a system configuration diagram of a washing dryer using the magnetocaloric effect. FIG. 5 is a perspective view of a magnetic field generator 18 that is a main component of the magnetic refrigeration apparatus 17. FIG. 6 is a diagram for explaining the operation of the magnetic refrigeration apparatus 17.

  In FIG. 4, the portion shown on the left side A portion shows the circulation system of the air flow 16 described above, and the air 16 a heated to the high temperature and low humidity by the heating means 22 passes through the drum inlet duct 25 to the drum 8. Supplied in.

  In the drum 8, the high-temperature and low-humidity air 16 a evaporates moisture from the garment 4 and deprives the garment of moisture, and the high-humidity air 16 b is sent to the drum outlet duct 24. Then, the high-humidity air 16 b is cooled and dehumidified by the cooling means 21, becomes low-temperature high-humidity air 16 c, and is sent to the heating means 22 again. The air 16 repeats the above circulation.

  Here, as an example, the temperature and relative humidity of the air flow 16 circulate as follows. The high temperature and low humidity air 16a has a temperature of 60 to 80 ° C., a relative humidity of 0 to 20%, the high humidity air 16b has a temperature of 40 to 60 ° C. and 80 to 100%, and the low temperature and high humidity air 16c has a temperature of 10 to 30. The temperature is about 80 to 100%.

  Of course, it goes without saying that the numerical values change depending on the surrounding environment (temperature and humidity of the outside air), the capacity of clothes to be dried, the driving pattern, and the like.

  In FIG. 4, the part shown on the right side B shows the system configuration of the magnetic refrigeration apparatus 17 which is the main part of the present invention. In this embodiment, a liquid is used as the heat medium 27, and water is used as a representative here.

  The flow path 31 through which the heat medium 27 flows is connected as a single flow path with the pump 20 interposed therebetween. Of the flow paths 31, the two flow paths in the magnetic field generator 18 are referred to as substance-containing tubes 28 and 29 in which the magnetic working material 19 is inserted inside the pipe. The cooling means 21 side of the magnetic field generator 18 is called the low temperature end 18a, and the heating means 22 side is called the high temperature end 18b.

  In the cooling means 21 and the heating means 22, for example, the heat medium (water) 27 flows in a pipe made of copper or aluminum having a good thermal conductivity, and the air (warm air) 16 flows between a number of thin aluminum fins. It is comprised with the cross fin tube type heat exchanger with which the medium 27 and the air 16 heat-exchange. The cooling means 21 and the heating means 22 may be heat exchangers composed of other types such as a corrugated fin heat exchanger.

  The water 27 used here may be pure water or soft water (water having little or no hardness component), or may be tap water or well water depending on the use situation. Furthermore, it may be mixed water mixed with antifreeze or the like so that it can be used even in cold regions.

  The pump 20 is configured by a reciprocating pump, a plunger pump, or the like that reciprocates the heat medium (water) 27 as indicated by an arrow 31 in the flow path (32 is a heat medium moving direction).

  The operation principle of the present invention will be described with reference to FIGS.

  The substance inclusion tubes 28 and 29 are connected by a fixing jig 34 and move together in pairs. The substance inclusion tube 28A and the substance inclusion tube 29A connected by the fixing jig 34A indicated by a solid line indicate a state where they are close to the permanent magnet A30a side (the positional relationship between the magnets 30A, 30B and the substance inclusion tubes 28, 29 is 7A), the substance inclusion tube 28B and the substance inclusion tube 29B connected by the fixing jig 34B indicated by a broken line are in a state of being close to the permanent magnet B30b side (the magnets 30A, 30B and the substance inclusion tube). (See FIG. 7B for the positional relationship between the tubes 28 and 29). That is, the substance inclusion tubes 28 and 29 can reciprocate in the substance inclusion tube movement direction 33 by, for example, a moving means (not shown) using the fixing jig 34.

  First, the case of the solid line described above will be described. In this case, the substance inclusion tube 28A enters the permanent magnet A30a, and the substance inclusion tube 29A protrudes from the permanent magnet A30a. In the magnetocaloric effect at this time, the magnetic working material 19 inserted into the substance-containing tube 28A generates heat due to the action of the magnetic field, and the magnetic working material 19 inserted into the substance-containing tube 29A deviates from the magnetic field. It absorbs heat.

  At this time, when the heat medium (water) 27 in the flow path 31a is caused to flow in the directions of the arrows 27a and 27b by the pump 20, the low temperature heat medium 27a (cold water) is placed at the low temperature end 18a of the magnetic field generator 18 (permanent magnet A30a). However, a high temperature heat medium 27b (warm water) is generated at the high temperature end 18b, and the heat medium 27 is sent to the cooling means 21 and the heating means 22, respectively.

  Then, the cold heat medium 27a sent by the flow path 31a into the pipe of the heat exchanger, which is the cooling means 21, exchanges heat with the high-humidity air 16b (see FIG. 4), deprives heat from the air 16b, and rises in temperature. After that, the cooling means 21 is exited.

  On the other hand, the high-humidity air 16b sent between the fins of the heat exchanger, which is the cooling means 21, exchanges heat with the heat medium 27a and is cooled by taking heat away from the heat medium 27a. Water is condensed. Thereafter, the low-temperature and high-humidity air 16 c dehumidified by moisture condensation exits the cooling means 21.

  On the other hand, the warm heat medium 27b sent by the flow path 31a into the pipe of the heat exchanger as the heating means 22 is composed of the low-temperature and high-humidity air 16c (see FIG. 4) produced and sent by the cooling means 21. After heat exchange, the heat is released to the air 16c and the temperature is lowered, and then the heating means 22 is exited.

  On the other hand, the low-temperature and high-humidity air 16c sent between the fins of the heat exchanger, which is the heating means 22, exchanges heat with the heat medium 27b, takes heat from the heat medium 27b, raises the temperature, and heats the heat means 22b. Exit.

  Then, the case of the broken line mentioned later is demonstrated. When the substance inclusion tubes 28 and 29 are moved from the solid line state to the broken line state by the substance inclusion tube moving direction 33 by the moving means (not shown) using the fixing jig 34, the substance inclusion tube 29B is now permanently moved. It has entered the magnet B30b, and the substance inclusion tube 28B protrudes from the permanent magnet B30b. In the magnetocaloric effect at this time, the magnetic working material 19 inserted into the substance-containing tube 29B generates heat due to the action of the magnetic field, and the magnetic working material 19 inserted into the substance-containing tube 28B deviates from the magnetic field. It absorbs heat.

  At this time, when the heat medium (water) 27 in the flow path 31b is caused to flow in the directions of the arrows 27c and 27d by the pump 20, the low temperature heat medium 27c (cold water) is placed at the low temperature end 18a of the magnetic field generator 18 (permanent magnet B30b). However, a high temperature heat medium 27d (warm water) is generated at the high temperature end 18b, and the heat mediums 27c and 27d are sent to the cooling means 21 and the heating means 22, respectively.

  The cold heat medium 27c sent by the flow path 31b into the pipe of the heat exchanger, which is the cooling means 21, exchanges heat with the high-humidity air 16b, takes heat away from the air 16b, and then exits the cooling means 21 .

  On the other hand, the high-humidity air 16b sent between the fins of the heat exchanger, which is the cooling means 21, exchanges heat with the heat medium 27c, is deprived of heat by the heat medium 27c, and is cooled. Water is condensed. Thereafter, the low-temperature and high-humidity air 16 c dehumidified by moisture condensation exits the cooling means 21.

  On the other hand, the warm heat medium 27d sent by the flow path 31b into the pipe of the heat exchanger which is the heating means 22 exchanges heat with the low-temperature and high-humidity air 16c sent by the cooling means 21, and the air After the heat is released to 16c and the temperature is lowered, the heating means 22 is exited.

  On the other hand, the low-temperature and high-humidity air 16c sent between the fins of the heat exchanger, which is the heating means 22, exchanges heat with the heat medium 27d, deprives the heat from the heat medium 27d, and rises in temperature. Exit.

  As described above, the magnetic field generator is always obtained by repeating the reciprocating movement of the substance inclusion tubes 28 and 29 in the substance inclusion tube movement direction 33 by the moving means using the fixing jig 34 (repetition from the solid line state to the broken line state). 18 (permanent magnet A30a), low temperature heat medium 27a, 27c (cold water) is generated at the low temperature end 18a, and high temperature heat medium 27b, 27d (warm water) is generated at the high temperature end 18b. By deriving to the cooling means 21 and the heating means 22 by the reciprocal movement for each, dehumidifying cooling and heating of the air 16 can be performed continuously.

  Here, the movement of the heat medium may be continuous reciprocation, but when the heat medium in the lowest temperature zone of the low temperature heat mediums 27a and 27c (cold water) reaches the cooling means 21, and the high temperature heat medium 27b. , 27d (warm water), when the heat medium in the highest temperature zone reaches the heating means 22, the drive of the pump 20 is temporarily stopped, and a heat medium stationary period (time) is provided. Efficient heat exchange may be achieved.

  Although depending on the specifications (size, etc.) of the cooling means 21 and the heating means 22, the stationary period of the heat medium may be about several seconds to several tens of seconds, for example.

  In the above embodiment, the substance inclusion tubes 28 and 29 are reciprocated in the substance inclusion tube movement direction 33 by the moving means using the fixing jig 34. Originally, the substance inclusion tubes 28 and 29 and the magnetic field generator 18 are moved. The relative positions of the permanent magnets A30a and B30b may be changed. Conversely, the substance-containing tubes 28 and 29 may be fixed and the permanent magnets A30a and B30b may be reciprocated.

  Further, as a method of changing the relative positions of the substance-containing tubes 28 and 29 and the permanent magnets A30a and B30b, other moving directions such as rotational movement may be used instead of reciprocating movement.

  FIGS. 8 and 9 are partially open perspective views of the substance inclusion tube showing an embodiment of the shape of the magnetic working substance 19 inserted into the substance inclusion tubes 28 and 29.

  FIG. 8 shows an embodiment in which the shape of the magnetic working material 19 is spherical (round), and FIG. 9 shows an embodiment in which the shape of the magnetic working material 19 is thin and elongated. Of course, the shape of the magnetic working material 19 is not limited to this, and the grains may be square (cube or cuboid), star-shaped, or a combination of FIGS. 8 and 9.

  Further, the magnetic working material 19 is preferably a ferromagnetic material, and gadolinium (Gd) and its alloys that can be used near room temperature, MnAs that is a ferromagnetic compound metal, and the like can be considered. However, the present invention is limited to these materials. It is not necessary, and it may be selected according to the required temperature specifications of the low temperature end 18a and the high temperature end 18b.

  FIG. 10 shows another embodiment of the present invention, which is different from the magnetic refrigeration apparatus 17 (see FIG. 6) in the case where the magnetic field generator 18 and the substance inclusion tube 28 are one system. By reciprocating in the substance inclusion tube moving direction 33, it enters the permanent magnet A30a (28A) or protrudes outside (28B), and exhibits the same magnetocaloric effect as described above.

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

  In the above embodiment, liquid and water are used as the heat medium 27, but gas and air may be used as the heat medium 27.

Therefore, the power consumption can be reduced compared with the electric heater type dryer or the washing dryer, and the humid environment or the high temperature air is not discharged into the washing dryer or the room so that the surrounding environment is not deteriorated. Reduces waste heat exhausted from the room to power consumption It is possible to reduce the.

  Further, in this embodiment, the magnetic working material member has a first magnetic working material member and a second magnetic working material member, and the magnetic field generator applies a first magnetic field to the first magnetic working material member. When the first magnet to be applied and the second magnet to apply the second magnetic field to the second magnetic working material member and the first magnetic field is applied to the first magnetic working material member, the second magnet The magnetic working material member is deviated from the second magnetic field, and when the second magnetic working material is applied to the second magnetic working material, the first magnetic working material member is configured to deviate from the first magnetic field. The heat medium can efficiently generate heat and heat absorption by the magnetic field.

  Further, in this embodiment, when the heat medium heated by the magnetic field generator passes through the heating means, the heat medium cooled so that the heat medium cooled by the magnetic field generator passes through the cooling means. By controlling the feeding means, the efficiently generated heating and the absorbed heat medium can be used for heating and cooling the drying air without waste.
