Description

  The present invention relates to a drum dryer having means for drying clothes.

  Drying clothes with a washing and drying machine that can perform washing to drying continuously creates high-temperature and low-humidity air with a blower fan and heat source, blows it into the washing tub, raises the temperature of the clothes, and moisture from the clothes By evaporating and evaporating the evaporated water. There are two methods for removing the evaporated water: an exhaust system that discharges it directly outside the washing and drying machine (always supplying new air) and a dehumidification system that cools the evaporated water and condenses it to remove the water (circulates the same air). However, for home use, a dehumidification system that does not allow moisture to enter the room where the washing and drying machine is installed is often used.

  The laundry dryer has (1) short drying time, (2) low power consumption, (3) good drying finish (low wrinkle of clothing), and (4) little damage to clothing. That is required. Among these, regarding (1) and (2), there is a washing and drying machine that efficiently performs drying by appropriately controlling the flow rate and temperature of air according to the progress of drying. In addition, there is a washing and drying machine that improves the movement of clothes in the washing tub and efficiently evaporates moisture from the clothes. Furthermore, there is a washing / drying machine that uses a water cooling system as a dehumidifying system to increase the efficiency of heat exchange with hot and humid hot air by allowing cooling water to flow uniformly over the wall surface of the air passage. In addition, there is a clothes dryer with low power consumption and high dehumidification rate by using a heat pump device as a heat source for drying clothes and circulating and drying air for drying.

  Regarding (4), there is a washing and drying machine provided with a low temperature drying course in which the temperature of the warm air is limited so that the temperature of the clothes does not rise too much (the heater input is suppressed). Regarding (3), since wrinkles are generated when clothes are entangled or twisted during drying, there are washing dryers that are less likely to cause tangling or twisting of clothes.

  Even if there is no entanglement or twisting, if the amount of clothing increases with respect to the volume of the dryer, the clothing cannot spread sufficiently, so that the clothing is dried while being folded and wrinkles are generated. As an example, FIG. 12 shows a photograph of clothing (cotton pajamas trousers) when 2 kg of clothing is dried by a commercially available clothing dryer (three types of drum volumes 62L, 77L, and 99L). It can be seen that the wrinkle decreases as the drum volume increases. In this way, it has been known that wrinkles can be reduced as the volume increases. However, in home-use washer / dryers, washing / drying is limited due to the size of the installation location and restrictions on the delivery path (corridor and door) to the installation location. There was a limit to the size of the machine, and it was difficult to ensure a sufficient volume. For this reason, clothing that cares about the finish of drying is separated from other general clothing, and there is only a method of drying by reducing the amount of clothing. However, it is not realistic to perform time-consuming drying several times, and many people do not use a dryer because such clothes are dried by hanging.

  An object of the present invention is to provide a drum-type drier having improved drying finish without increasing the drum volume with low power.

  In order to achieve the above object, the present invention provides a rotating drum that accommodates clothing, an outer tub that encloses the rotating drum, a motor that drives the rotating drum, a housing that supports the rotating drum, and a compression The refrigerant is compressed by the machine, the air is heated by the condenser that dissipates the heat of the compressed refrigerant, the pressure of the refrigerant is reduced by the expansion mechanism, and the air is reduced by the evaporator in which the reduced pressure refrigerant absorbs the surrounding heat. In a drum-type dryer having a heat pump for dehumidification and circulating the air in the order of the condenser, the rotary drum, the evaporator, and the condenser by a blower unit during a drying operation, the opening of the outer tub An air outlet is provided at a position above the outer tub cover provided on the air tank, and the blower unit uses a turbo fan, and blows high-speed air sent from the turbo fan rotated at high speed to the clothing. Only, characterized in that to extend the wrinkles of the clothes in the wind force of the high velocity air.

  Further, the blowout port is provided at a position obliquely above and to the right of the outer tub cover, and the blower unit is provided on the upper right side in the housing.

  The drum dryer configured in this manner blows high-speed air on the clothes during the drying operation, so that the clothes are pushed out by the wind, and the wrinkles of the clothes are stretched to achieve a dry finish with less wrinkles.

  In addition, power consumption can be greatly reduced by using a heat pump device with higher thermal efficiency than conventional heater type as a heat source for drying clothes, and moisture can be evaporated by blowing high-speed air to stretch wrinkles. And the drying time is shortened. Furthermore, since the heat pump system with high efficiency can suppress the current compared to the conventional heater system, the current of the blower motor can be increased accordingly. As a result, it is possible to flow a large amount of air even with low temperature warm air, and drying can be performed for a short time while suppressing shrinkage of clothing, and furthermore, a finish with less wrinkles and shrinkage can be realized.

  The outer tub 2 is supported in a vibration-proof manner by a suspension 5 (consisting of a coil spring and a damper) whose lower side is fixed to the base 1h. The upper side of the outer tub 2 is supported by an auxiliary spring (not shown) attached to the upper reinforcing member, and prevents the outer tub 2 from falling in the front-rear direction.

  Reference numeral 19 denotes a detergent container provided on the upper left side in the housing 1, and a drawer-type detergent tray 7 is mounted from the front opening. When putting detergents, the detergent tray 7 is pulled out as shown by a two-dot chain line in FIG. The detergent container 19 is fixed to the upper reinforcing material of the housing 1.

The top cover 1e is provided with a water supply hose connection port 16a from a water tap and a water absorption hose connection port 17a for remaining hot water in the bath. The detergent container 19 is connected to the outer tub 2 and supplies washing water to the outer tub 2 by opening the water supply electromagnetic valve 16 or operating the bath water supply pump 17.

  Reference numeral 29 denotes a blower duct installed vertically inside the back surface of the housing 1, and a lower portion of the duct is connected to an intake port 2 a provided below the back surface of the outer tub 2 by a rubber bellows tube B 29 a.

  The upper part of the air duct 29 is connected to a filter duct 27 installed in the vertical direction behind the upper part in the housing 1. The lower surface of the filter duct 27 has an opening, and a drawer-type drying filter 8 is inserted into the opening. The air that has entered the filter duct 27 from the blower duct 29 flows into the mesh filter 8a of the drying filter 8, and lint is removed. Cleaning of the dry filter 8 is performed by pulling out the dry filter 8 and taking out the mesh filter 8a. An evaporator 37 is installed on the downstream side of the filter duct 27, and an intake duct 33 is connected to the downstream side thereof. The other end of the intake duct 33 is connected to the intake port of the blower unit 28.

  The blower unit 28 includes a drive motor 28a, a fan impeller (not shown), and a fan case 28b. The fan case 28b has a built-in condenser 31 to heat the air sent from the fan impeller. The discharge port of the blower unit 28 is connected to the hot air duct 30. The hot air duct 30 is connected to a hot air outlet 32 provided in the outer tank cover 2d through a rubber bellows tube A30a and a bellows tube joint 30b. In the present embodiment, since the blower unit 28 is provided on the upper right side in the housing 1, the hot air outlet 32 is provided at a position diagonally above and to the right of the outer tank cover 2d, and the distance to the hot air outlet 32 is set. I try to keep it as short as possible.

  The heat pump cycle mainly includes a compressor 35, a condenser 31, an expansion mechanism 36, and an evaporator 37, and the refrigerant flow is as follows. The high-temperature and high-pressure gas compressed by the compressor 35 is heat-exchanged with air by the condenser 31. Thereafter, the refrigerant decompressed by the expansion mechanism 36 is evaporated by the evaporator 37, and the low-pressure gas is returned to the compressor 35. Here, when the refrigerant evaporates in the evaporator 37, the humid air that has passed through the filter duct 27 is cooled and dehumidified and reheated in the condenser 31.

  Temperature sensors (not shown) are provided at the outlet 2b and the inlet and outlet of the blower unit 28.

  A feature of the present invention is that high-speed air is directly applied to the garment, and wrinkles generated in the garment are stretched by the force of air. For this purpose, a blower unit 28 that generates high-speed air and a hot air outlet 32 that directly applies the air to clothing are required. The performance required for the blower unit will be described later. Details of the hot air outlet 32 will be described with reference to FIGS. 6 is a front view of the outer tub cover 2d of the hot air outlet 28 installation portion, and FIG. 7 is a cross-sectional view of the hot air outlet 32 cut along a two-dot chain line AA in FIG.

  The hot air outlet 32 is provided along the opening 2c from the front side of the outer tub cover 2d, and flow paths 32b and 32c are formed therein. A bellows pipe joint 30b is attached to the inlet of the hot air outlet 32, and a nozzle 32d is formed at the outlet of the flow path 32c. The inner diameter of the opening 2c of the outer tub cover 2d and the inner diameter of the opening 3a of the washing / dehydration tub 3 are set to be substantially the same so that clothing does not enter between the gap between the washing / dehydration tub 3 and the outer tub cover 2d. Yes. For this reason, the outlet 32a of the hot air outlet 32 is formed so as to protrude inward from the inner peripheral surface of the opening 2c, and the nozzle 32d is opened toward the washing and dewatering tub 3. By doing in this way, the warm air which came out of the nozzle 32d can be directly applied to the clothing in the washing and dewatering tank 3.

  In addition, if the amount of protrusion of the outlet portion 32a is too large, the movement of clothing is hindered during washing or drying. Therefore, as shown in FIG. 6, the nozzle is formed into a flat slit shape to reduce the amount of protrusion, and the opening 2c and the outlet The surface shape of the portion 32a is changed smoothly. Further, the flow path 32b and the flow path 32c are configured so that there is no useless protrusion or a sudden change in the flow direction, and the flow path area gradually decreases toward the nozzle 32d. By doing so, it is possible to reduce pressure loss and fluid noise that occur when high-speed air flows through the flow paths 32b and 32c.

  The air flow during the drying operation is as follows. By operating the blower unit 28 and operating the compressor 35 of the heat pump, the condenser 31 generates heat, high-speed hot air blows into the washing and dehydrating tub 3 from the nozzle 32d (arrow 41), hits the wet clothes, Warm clothes and water evaporates from clothes. The air that has become hot and humid flows from the through hole provided in the washing and dewatering tub 3 to the outer tub 2 and is sucked into the air duct 29 from the air inlet 2a and flows from the bottom to the top (arrow 42). Enter the duct 27 (arrow 43). The lint is removed through the mesh filter 8 a provided in the filter duct 27 and enters the evaporator 37. The hot and humid air is cooled and dehumidified by coming into contact with the low-temperature evaporator 37, becomes dry low-temperature air, enters the intake duct 33, and is sucked into the blower unit 28 (arrow 44). Then, it is heated again by the high-temperature condenser 31 and circulates so as to blow into the washing and dewatering tub 3.

  FIG. 8 is an example of the results of examining the wind speed ejected from the nozzle 32d and the finish of the clothes after drying when the drying operation as described above is performed. The wind speed and the air volume were adjusted by changing the rotation speed of the motor 28a and the area of the nozzle 32d. The wind speed is a value calculated from the result of measuring the flow pressure characteristic of the blower unit 28. The flow pressure characteristics were measured with the apparatus shown in FIG. An orifice is attached to the suction port of the pressure equalizing box and the discharge port of the blower unit 28, and the flow rate and the pressure of the intake port and the discharge port of the blower unit 28 are measured while varying the diameter of the orifice and the rotation speed of the motor 28a. The characteristics were determined. Then, the pressure of the air inlet and outlet of the air blowing unit 28 when the air blowing unit 28 is mounted on the washing / drying machine is measured, the flow rate is obtained from the above flow rate pressure characteristics, and the value obtained by dividing the flow rate by the nozzle area is the wind speed. It was.

  The experimental conditions are as shown in the figure, and the testing machine is a drum-type washing and drying machine having a washing and dewatering tank having a diameter of 600 mm and a volume of 75 L, and the amount of cloth is 2 kg. Finished evaluation was performed on various garments, but the results for thin cotton pajamas trousers with the most wrinkles were shown. The evaluation is a five-step sensory evaluation by visual inspection. FIG. 10 shows an example of the finished condition with respect to the sensory evaluation value. The upper nozzle is a case where the nozzle 32d is provided at the above-described position (a position obliquely above and to the right of the outer tub cover 2d), and the lower nozzle is a case where it is provided below the outer tub cover 2d. The blowing direction of the wind from the nozzle 32d was made to face substantially the center of the bottom wall of the washing and dewatering tank 3. The result is an average value of three evaluators.

From the figure,
(A) The finish improves as the wind speed increases. However, if the wind speed is too high, the finish is worsened (from the data of the upper nozzle 1.5 m ³ / min).
(B) If the wind speed is the same, the higher the flow rate, the better the finish, but the difference between the flow rate of 1.5 m ³ / min and 1.7 m ³ / min is small.
(C) Comparing at the same wind speed and flow rate, it can be seen that the lower nozzle has a better finish than the upper nozzle. Thus, the higher the wind speed, the better the finish, but the higher the flow rate, the better. Therefore, it is desirable not to increase either one but to set the balance in consideration of the balance between the two. Specifically, not only the finish, but also the current value (in the case of a commercial power supply for home use, the total of the blower unit 28, the compressor 31, the motor 4, and the control device 38 is 15 A or less), the drying performance, and the wind circulate. It is necessary to determine the wind speed and flow rate in consideration of the flow area of the duct and mounting on the washing and drying machine.

If the sensory evaluation value is 4 or more, there is little dissatisfaction even if the clothes after drying are worn as they are. In order to obtain a sensory evaluation value of 4 or more in this experimental machine, the upper nozzle requires a flow rate of 1.5 m ³ / min and a wind speed of 90 m / s or more. However, since the finish tends to deteriorate if the wind speed is too high, it is better to suppress the wind speed to about 130 m / s at the maximum. Further, the finish is best at a wind speed of 100 to 120 m / s. In the case of the lower nozzle, a flow rate of 1.5 m ³ / min and a wind speed of 60 m / s or more are necessary. However, since the finished condition hardly changes at a wind speed of 80 m / s or more, the maximum may be about 80 m / s. The nozzle area for generating the wind speed is 190 to 280 mm ² in the case of the upper nozzle and 310 to 415 mm ² or less in the case of the lower nozzle. Accordingly, the blower unit 28 needs to have a performance that allows the flow rate to flow from the nozzle having the area. In this embodiment, the nozzle position is the upper nozzle, the nozzle area is 250 mm ² (on the slit having a width of 50 × the height of 5 mm), and the blower unit 28 has a fan impeller diameter of 140 mm and a blade thickness of 7 mm, and the number of revolutions per minute. Driving at 16000 rpm. As a result, the fan discharge pressure is about 7500 Pa (at an air temperature of 30 ° C.), and a wind speed of about 100 m / s is obtained at a flow rate of about 1.5 m ³ / min.

  In the case of clothing that is difficult to wrinkle, a finish with a sensory evaluation value of 4 or more can be obtained even at a value lower than the above wind speed. However, it is common to dry various clothing at the same time. It is better to determine the wind speed.

  The reason why the wrinkle of clothing is reduced by applying high-speed air to the clothing will be described with reference to FIG. FIG. 11A is a schematic diagram when the high-speed air 41 exiting from the nozzle 32d hits the clothing. Here, the case where there is other clothing on the back of the clothing is shown. When the air hits the clothing, the clothing is forced to be spread by the air (arrow (1)), and after it hits the clothing, the direction of flow is changed and the air flowing along the clothing surface is pulled left and right (arrow (2)). ) Acts. The wrinkles of clothes are stretched by the force of (1) and (2). When the amount of clothes in the washing and dewatering tub 3 is large, wrinkles are stretched mainly by the force of (1) because many other clothes are difficult to move freely around the clothes directly exposed to air. When the amount of clothing is small, the clothing moves freely, and the clothing that has been struck with air is blown while being pushed in the direction of air flow, and wrinkles are caused by the force of (2) caused by the air flowing along the clothing surface. Stretched. When the amount of clothing is small, the clothing spreads during drying and wrinkles are unlikely to occur, so the force (1) is considered here.

  As shown in FIG. 11B, the force F in (1) is proportional to the product of Q and V, where Q is the flow rate of the wind blown from the nozzle 32d and V is the wind speed. If the distance between the nozzle 32d and the clothing is X, the force F is proportional to V and inversely proportional to X. However, when the distance between the nozzle 32d and the clothing is very close (from the core region of the jet, from the nozzle to a position about 6 times the nozzle diameter in the case of a circular nozzle), F is proportional to V regardless of X. Therefore, in order to increase F, the flow rate Q is increased, the wind speed V is increased, or X is decreased (clothes are brought closer to the nozzle). The finishing result shown in FIG. 8 can be explained with this.

  In order to increase the flow rate Q, it is necessary to increase the rotational speed of the fan of the blower unit 28 or to increase the outer diameter or blade height of the fan. Also, it is better to reduce the pressure loss by increasing the area of the duct through which the hot air passes. However, if the flow rate is significantly increased, the size of the duct and the blower unit increases, leading to an increase in the size of the housing 1 and it becomes difficult to install the washing and drying machine in the home.

  On the other hand, in order to increase the wind speed V, the air blowing unit 28 may be a pressure type to reduce the nozzle area. When a general turbofan is used as the blower unit 28, there are a method of increasing the diameter of the fan impeller at a low rotational speed and a method of increasing the rotational speed while keeping the diameter of the fan impeller small. High-speed rotation has the advantage that it can be mounted in the same housing as the conventional one.

  In the finishing test results shown in FIG. 8, when the wind speed was too high, a phenomenon in which the finishing deteriorated was observed. This cannot be explained above. Observing the movement of the clothing during the experiment, it was found that if the wind speed was too high, there was a phenomenon in which the clothing was twisted by the wind. Therefore, this is the cause of deterioration of the finish.

  In order to reduce the distance X between the nozzle 32d and the garment, the nozzle 32d may be provided near the place where the garment always passes during drying. Accordingly, the position of the nozzle 32d may be provided at the position where the lifter 3b lifts the clothes, that is, the lower side of the washing and dewatering tub 3 (the lower side of the outer tub cover 2d). By providing the nozzle below, the finish can be improved even when the wind speed is about 60 m / s as shown in FIG. 7, so the pressure and flow rate of the blower unit 28 can be reduced compared to when the nozzle is above. There is an advantage that the rotational speed of the fan impeller can be reduced. Also, if the nozzle is at the bottom, the wind blowing direction and the direction of gravity are reversed. When the wind hits the garment, the garment is difficult to escape due to its own weight, and the force F acting on the garment is not attenuated, so that the finish can be further improved.

  When the nozzle 32d is provided on the lower side, the installation of the air duct 29 and the air unit 28 on the lower side of the outer tub 2 can be made compact in terms of mounting. However, since the washing water at the time of washing enters from the nozzle 32d and flows into the blower unit 28, it is necessary to take measures such as providing a water entry prevention mechanism or a waterproof blower unit.

  In the present embodiment, the nozzle 32d is provided at a position obliquely above and to the right of the outer tub cover 2d, so there is no fear that the washing water will enter. In this case, it is necessary to appropriately control the number of rotations of the washing and dewatering tank 3 so that the clothes are lifted up to the vicinity of the nozzle 32d so that the wind as fast as possible hits the clothes. The clothes are lifted upward by the centrifugal force generated by the rotation of the washing and dewatering tank 3 and the lifter 3b. For this reason, the number of rotations has an optimum value according to the diameter of the washing and dewatering tub 3, and the number of rotations decreases as the diameter increases. However, there are clothes that fall quickly due to gravity, and it is inevitable that the distance between the average nozzle and the clothes will be longer than when the nozzle is provided on the lower side. Therefore, as shown in FIG. Need to increase.
