Description

  The present invention relates to a washing and drying machine that performs washing and drying used in a general household in the same tank.

  Conventionally, as a device for washing and drying clothes, there are a device using a heater as a heat source and a device using a heat pump device as a heat source (see, for example, Patent Document 1). A conventional example will be described below with reference to the accompanying drawings.

  FIG. 16 is a cross-sectional side view of a conventional washing / drying machine described in the above-mentioned document. In FIG. 16, the washing and drying machine 1 has a casing 2, and a door 12 for attaching and removing clothes 6 is attached to the center of the casing 2, and a rotating drum 3 is accommodated therein. A predetermined portion of the rotating drum 3 is provided with a beater 5 for lifting and dropping the clothes 6 along with the rotation of the rotating drum 3, and a punching hole 4 through which washing water 7 and circulating air 9 for drying enter and exit. . The shaft 11 of the rotating drum 3 receives power for rotation from a driving motor (not shown).

  Further, the rear surface of the rotating drum 3 in the casing 2 is partitioned by a partition wall 22 except for the air inlet 24 and the air outlet 23, and ducts 10 and 13 through which the circulating air 9 passes are formed. The lower part of the front surface of the partition wall 22 constitutes a washing tub 14, and the lower part of the rotating drum 3 faces the portion of the washing tub 14.

  Each of the air ducts 10 and 13 incorporates a compressor 19, a condenser (condenser) 18, a fan 17, an expansion valve 20, an evaporator (evaporator) 15 and the like, and a so-called heat pump cycle is formed. Further, a part of the capacitor 18 is extended to the outer back surface of the casing to form a radiator 16. 21 is a drain drain pipe, and 8 is a washing drain pipe.

  Next, each process and operation will be described. In the washing and rinsing process, the door 12 is opened, the garment 6 and an appropriate amount of detergent are added, the door 12 is closed, and the following processes are executed.

  A prescribed amount of water 7 is supplied from a water supply valve (not shown) to the washing tub 14 up to the position of the water level A. The rotating drum 3 rotates continuously or intermittently at the programmed number of rotations to perform cleaning. During this time, the garment 6 is lifted and dropped by the beater 5. After washing is completed, the water is drained from the washing drain pipe 8 of the washing tub 14 to the outside of the machine.

  Subsequently, the rinsing process is performed in the same process. Rinsing water is also drained out of the machine from the washing drain pipe 8 as washing drain.

  In the dehydration step, the rotating drum 3 rotates at a programmed number of rotations to dehydrate the moisture 7 in the clothing 6. The dewatered water is drained out of the machine from the washing drain pipe 8 as washing drain.

  In the drying process, the compressor 19, the fan 17 and the rotating drum 3 are operated, and the circulating air 9 circulates inside the ducts 10 and 13 and the rotating drum 3.

  The water vapor evaporated from the clothing 6 is brought into contact with the evaporator 15 through the air outlet 23 and the duct 10 together with the circulating air 9, and is cooled to be condensed and condensed (condensed water). The dehumidified circulating air 9 is sent to the condenser 18 by the fan 17, heated here to become hot air, flows into the rotary drum 3 through the duct 13 and the air inlet 24, and evaporates moisture from the clothing 6 again. . The dehumidified condensed water is drained out of the machine through the drain drain pipe 21.

During this time, the rotating drum 3 rotates continuously or intermittently at a preset number of rotations as in the washing process. The process of continuously performing from washing to drying has been described above.
Japanese Examined Patent Publication No. 6-75628

  However, in the conventional configuration, the drain drain pipe 21 and the washing drain pipe 8 separately lead the drain to the outside of the machine. In the washing machine, there is one drainage hose corresponding to the drainage pipe, and when a washing / drying machine is installed at the place where the washing machine is installed, the drainage treatment can be performed with one drainage hose as before, It is desirable in terms of installation work, installation members such as a waterproof floor, and piping equipment under the floor.

  Further, if the drain drain pipe 21 and the laundry drain pipe 8 are connected as they are in the machine, the water level stored in the washing tub 14 during washing is high, and the drain drain pipe 8 drains from the laundry drain pipe 8 by water pressure during the washing drain. When washing water and rinsing water flow into the pipe 21 and not only the pipe but also the installation position of each means such as the evaporator 15, the fan 17 and the condenser 18 for performing dehumidification and heating is lower than the stored water level of the washing water, Each means has a problem that it may get wet with washing water in which a detergent or a bleaching agent is dissolved, thereby causing problems such as poor insulation and corrosion. In order to prevent this, in addition to the drainage valve provided in the washing drainage pipe 8, a backflow by a check valve for preventing the backflow to the drain drainage pipe 21 or a drainage valve for the drain drainage pipe 21 is provided. There has been a problem that a separate prevention means is required.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to realize a waste water treatment means that can drain washing water and condensed water at the time of drying out of the apparatus with a single drain pipe.

  In order to achieve the above object, the present invention includes a wastewater treatment means for draining outside a machine by connecting a washing drainage channel for draining wastewater during washing and a condensation drainage channel for passing condensed water during drying to a single water distribution pipe. The drainage treatment means comprises a drainage tank for accumulating dew condensation water, a drainage pump for discharging water in the drainage tank, a water level detection means for detecting the water level in the drainage tank, and the operation of the drainage pump. Control means for controlling is provided, and the control means operates the drain pump when the water level detection means detects a predetermined water level.

  As a result, when the high water level is detected by the water level detecting means for detecting the water level in the drain tank, the drain pump is operated, and when the low water level is detected by the water level detecting means, the drain pump is stopped. Thus, waste water treatment means that can drain to the outside of the machine will be realized.

  The washing / drying machine of the present invention can realize waste water treatment means capable of draining outside the machine with one drain pipe as in the washing machine.

  The first invention performs washing and drying on clothes put in the same tank, and at the time of drying, dehumidifying means for collecting moisture from the drying air as condensed water, and a washing drainage channel for flowing wastewater during washing A drainage treatment means for draining the outside of the machine by connecting a condensation drainage channel for passing the condensation water during drying to a single distribution pipe, the drainage treatment means comprising: a drainage tank for accumulating condensation water; and a drainage tank in the drainage tank. A drainage pump for discharging water, a water level detection means for detecting the water level in the drainage tank, and a control means for controlling the operation of the drainage pump, wherein the control means detects the predetermined water level. In this case, since the drainage pump is operated, the drainage operation is performed at an appropriate timing, and a drainage treatment unit that can drain out of the apparatus with a single drainage pipe can be realized.

  In a second invention, the control means of the first invention includes an operation time setting means for setting an operation time of the drainage pump, and when the water level detection means detects a predetermined water level, the drainage pump is connected to the operation time. By performing the operation for the time set by the setting means, the drainage operation is performed at an appropriate timing, and a wastewater treatment means capable of draining outside the apparatus with a single drainage pipe can be realized.

  According to a third aspect of the present invention, the control means of the second aspect of the invention is configured to continue the operation of the drainage pump when the predetermined water level is detected after being operated for the time set by the operation time setting means. As a result, the drainage operation is performed at an appropriate timing, and a drainage treatment means that can drain out of the apparatus with a single drainpipe can be realized.

  According to a fourth aspect of the present invention, when the water level detection means detects a predetermined water level and continues the operation of the drainage pump, the control means of the second invention extends the operation time from the next time on by the operation time setting means. By doing so, it is possible to perform drainage operation at an appropriate timing, and it is possible to realize drainage treatment means that can efficiently drain out of the machine in response to an increase in dehumidification amount.

  According to a fifth aspect of the present invention, when the control means of the second invention is operated for the time set by the operating time setting means, the water level detection means stops the operation of the drain pump without detecting a predetermined water level. By shortening the operation time with the operation time setting means, drainage operation can be performed at an appropriate timing, unnecessary operation of the drainage pump can be reduced, and dehumidified water can be rationally removed from the machine. It can be drained.

  According to a sixth aspect of the present invention, the control means of the first aspect of the invention comprises a non-operation time setting means for setting a non-operation time of the drainage pump, and the time set by the non-operation time setting means has elapsed after the start of the drying operation. By operating the drainage pump in some cases, the drainage operation can be performed at an appropriate timing, unnecessary operations of the drainage pump can be reduced, and dehumidified water can be rationally drained outside the machine. .

  In a seventh aspect, when the control means of the sixth aspect is operated for the time set by the operation time setting means, the water level detection means detects a predetermined water level and continues the operation of the drainage pump. Since the non-operation time is shortened by the operation time setting means, the drainage operation is performed at an appropriate timing, and a drainage treatment means that can drain out of the apparatus with a single drainage pipe can be realized.

  In the eighth invention, the control means of the sixth or seventh invention extends the non-operation time by the non-operation time setting means when the water level detection means does not detect the predetermined water level and stops the operation of the drainage pump. By doing so, the drainage operation is performed at an appropriate timing, and a drainage treatment means that can drain out of the apparatus with a single drainpipe can be realized.

  According to a ninth invention, the control means of any one of the first to eighth inventions comprises a drain pump operating time measuring means for measuring an operating time of the drain pump, and a predetermined time elapses after the drain pump operation starts. However, when the water level detection means detects the predetermined water level, the operation of the washing / drying machine is stopped, so that the draining operation is performed at an appropriate timing, and one drain pipe is used for the outside of the machine. A wastewater treatment means capable of draining can be realized.

  According to a tenth aspect of the present invention, the control means of any one of the first to ninth aspects includes a drainage pump operating time measuring means for measuring an operating time of the drainage pump, and a predetermined time has elapsed after the drainage pump operation is started. If the water level detection means still detects the predetermined water level, the operation of the washer / dryer should be temporarily stopped, the drain pump operation should be continued, and the water level detection means no longer detects the predetermined water level. By restarting the operation of the washing / drying machine, the drainage operation is performed at an appropriate timing, and a drainage treatment unit that can drain the outside of the machine with one drainpipe can be realized.

  According to an eleventh aspect, the control means of the ninth or tenth aspect of the invention comprises an informing means for informing the abnormality of the wastewater treatment, so that the abnormality of the wastewater treatment means can be informed to the outside, and the wastewater treatment The user can be notified of the abnormality of the means.

In FIG. 1, a washing tub 26 is provided in a washing / drying machine main body 25 of the present invention, and a motor 27 is attached thereto. The washing tub 26 is attached to the main body 25 by being supported by suspensions 29 on both sides and an upper suspension 30.

  The compressor 35 compresses the vaporized refrigerant, the radiator 36 radiates the heat of the compressed high-temperature and high-pressure refrigerant, and the throttling means 37 from an expansion valve or a capillary tube for reducing the pressure of the high-pressure refrigerant. In the heat absorber 38, the refrigerant whose pressure has been reduced to low pressure takes heat from the surroundings, and the compressor 35, the radiator 36, the throttle means 37, and the heat absorber 38 are connected in this order, and the refrigerant circulates again in the compressor 35. Thus, a heat pump device connected by a pipe line 39 is provided.

  The air path 40 is configured to connect the heat absorber 38 as a dehumidifying means for cooling the drying air and the radiator 36 as a heating means for heating the drying air. The washing tub 26 and the air passage 40 are connected by flexible hoses 41 and 42. The air passage 40 is provided with air blowing means 43. The duct 44 is provided on the outer wall of the washing tub 26. An arrow B indicates the flow of drying air in the duct 44 and the air passage 40.

  In FIG. 2, the rotating drum 28 is attached directly to the shaft of the motor 27 and installed in the washing tub 26. A door 32 for loading clothes 31 is provided at a position corresponding to the front opening of the washing tub 26 and the rotary drum 28. A gap between the main body 25 and the washing tub 26 is substantially sealed by a bellows 33 and a door packing 34 so that air does not leak into the main body 25 or outside the machine. A hole 45 and an opening 46 through which washing water and drying air enter and exit are provided on the side wall and the bottom of the rotating drum 28. The opening 56 is provided on the inner wall of the washing tub 26 and connects the air passage between the washing tub 26 and the duct 44. An arrow C indicates the flow of drying air in the washing tub 26 and the rotary drum 28.

  The laundry drainage channel 47 is a channel for draining wastewater during washing. The condensation drainage channel 48 allows the condensed water generated in the heat absorber 38 during drying to flow. The washing drainage channel 47 and the condensation drainage channel 48 are connected to a single drainage pipe 49. The tip 50 of the drain pipe 49 is open to the atmosphere outside the machine.

The drainage channel 48 side is closed. When the washing drainage channel 47 side is open, the condensation drainage channel 48 side is closed, thereby constituting a backflow prevention means for preventing a backflow from the washing drainage channel 47 to the condensation drainage channel 48.

  FIG. 4 is a flowchart showing control by the control means 72. In step ST1, it is determined whether or not the drainage pump 68 is in operation. If it is not in operation, it is determined in step ST2 whether or not the water level information transmitted from the water level detection means 71 is “high water level”. If it is “high water level”, the drainage pump 68 is operated in step ST3. If the water level information is not “high water level” in step ST2, the stoppage of the drainage pump 68 is continued in step ST4. If the drainage pump 68 is not operating in step ST1, it is determined in step ST5 whether or not the water level information transmitted from the water level detection means 71 is “low water level”.

By having the control means 72 for performing the control, the drainage operation is performed at an appropriate timing, and it is possible to realize a drainage treatment means capable of draining outside the machine with one drainpipe as in the washing machine.

  In the present embodiment, an example is shown in which a heat pump device is used as a heat source. However, other heat sources such as a heater or an induction heating device may be used.

  Moreover, although the heat exchanger of the heat radiator 36 and the heat absorber 38 shown in this Embodiment has shown the tube type heat exchanger with a plate fin, the form is not specifically limited.

  In addition, one or a plurality of threshold values predetermined for the water level detection means may be used. In one case, “high water level” and “low water level” are determined by comparing the threshold value and the water level. One threshold is set as the “high water level threshold”, and if the water level is higher than the “high water level threshold”, it is determined as “high water level”, and any one threshold lower than the “high water level threshold” is set as “low water level threshold”. If the water level is lower than the “low water level threshold”, it is determined that the water level is “low water level”.
