As shown in FIG. 1, the washing machine 200 according to the present embodiment includes at least a washing machine body 210, an operation unit 8 </ b> A provided on the upper part of the washing machine body 210, and a transmission / reception unit 230.

In addition, the communication system of the washing machine according to the present embodiment is configured by performing data communication between the transmission / reception unit 230 of the washing machine 200, the portable information terminal 220, and the transmission / reception unit (not shown).

At this time, data communication is performed by short-range wireless communication between the transmission / reception unit 230 provided in the washing machine body 210 and the transmission / reception unit of the portable information terminal 220 according to, for example, a protocol based on the NFC (Near Field Communication) standard. Note that the NFC standard is a short-range wireless communication technology that is approved as an international standard, and devices that are equipped with transmission / reception units of the same NFC communication standard can communicate bidirectionally. For this reason, short-range wireless communication technology according to the NFC standard is currently widely used as a payment service for, for example, transportation cards, electronic money, and portable information terminals (for example, mobile phones).

Therefore, also in the communication system of the washing machine 200 of the present embodiment, a communication method based on the NFC standard is used for data communication between the transmission / reception unit 230 of the washing machine body 210 and the transmission / reception unit of the portable information terminal 220, A configuration for performing data communication by bidirectional communication is provided.

Furthermore, as shown in FIG. 2, the washing machine 200 of the present embodiment includes at least the rotating drum 1, the water tank 2, the control circuit 100, and the circulation air flow paths 9 and 11 housed in the washing machine body 210. The operation unit 8 </ b> A and the transmission / reception unit 230 are configured.

The water tank 2 is disposed in the washing machine main body 210 in a suspended state by a suspension structure (not shown).

Rotating drum 1 has a bottomed cylindrical shape and is contained in water tank 2. At this time, the rotating drum 1 is arranged such that the axial center direction of the rotating drum 1 is inclined downward from the front side (left side in FIG. 2) to the back side (right side in FIG. 2).

Further, a large number of through holes 1a communicating with the water tank 2 are formed on the inner peripheral wall of the rotary drum 1, and stirring protrusions (not shown) are formed at a plurality of positions on the inner peripheral wall. The rotating drum 1 is rotationally driven in the forward and reverse directions by a motor 3 attached to the back side of the water tank 2 (right side in FIG. 2). Thereby, the laundry accommodated in the rotating drum 1 is washed.

Further, on the front side of the water tank 2 (left side in FIG. 2), a clothing entrance 1 b leading to the opening end of the rotating drum 1 is formed. Furthermore, a door 35 is provided on the front side of the washing machine main body 210 so that an opening provided on the upward inclined surface of the washing machine main body 210 can be opened and closed. Then, by opening the door 35, the laundry can be taken in and out of the rotary drum 1 through the clothing entrance 1b. At this time, since the door 35 is provided on the upward inclined surface, the user can take in and out the laundry without bending his / her waist. Thereby, the workability | operativity at the time of putting in / out of a laundry can be improved compared with the drum type washing-drying machine which has an opening part in a general horizontal direction.

The water tank 2 is connected to a water injection pipe (not shown) having a water injection valve and a water discharge pipe 40 having a water discharge valve 27. Then, by controlling the water injection valve and the drain valve 27, water is injected into the water tank 2 and drained from the water tank 2.

Further, as shown in FIG. 2, the control circuit 100 controls the water supply and drainage into the water tank 2 and the rotation of the rotating drum 1 to perform washing, rinsing and dehydration steps (hereinafter, these three steps). Are also referred to as “washing operation”).

For example, the control circuit 100 drives the blower fan 4 that is a blower, and performs control to circulate the air in the water tank 2 through the circulation airflow paths 9 and 11 including the dehumidifying part and the heating part. In addition, a dehumidification part and a heating part are comprised by the evaporator 19 and the condenser 17 which comprise the air conditioner connected, for example with the compressor 16 with the refrigerant circuit.

That is, the control circuit 100 controls the blower fan 4 to introduce wet air containing water vapor in the water tank 2 from the circulation air introduction pipe 5 to the circulation blower paths 9 and 11. And the water vapor | steam in the introduce | transduced air is condensed with the evaporator 19, and it is set as dry air. Further, the dry air is heated again by the condenser 17 and blown into the water tank 2 as dry high-temperature air. Thereby, the laundry can be efficiently dried by exposing the laundry in the rotating drum 1 by repeatedly circulating hot dry air.

As described above, the washing machine and the washing machine communication system of the present embodiment are configured.

Hereinafter, the washing operation of the washing machine executed by the control circuit 100 will be described. The detailed configuration and operation of the control circuit 100 will be described later with reference to FIG.

First, the user opens the door 35 of the washing machine 200 and puts laundry and detergent into the rotary drum 1. And a user operates the operation part 8A provided in the front upper part of the washing machine main body 210, and inputs a driving course etc., for example. Thereby, the control circuit 100 controls each apparatus according to the inputted driving | running course, and starts the washing operation shown below.

First, the control circuit 100 controls the water injection valve to inject a predetermined amount of water into the water tank 2 from the water injection pipeline. Then, after water injection, the control circuit 100 controls the motor 3 to rotate the rotary drum 1. Thereby, the washing step of the washing machine is started.

At this time, the laundry accommodated in the rotating drum 1 is lifted in the rotating direction by the stirring protrusion provided on the inner peripheral wall of the rotating drum 1 by the rotation of the rotating drum 1, and is lifted from an appropriate height. The so-called stirring operation of falling is repeated. Thereby, the laundry is washed by receiving the action of tapping.

Then, after a predetermined washing time has elapsed, the control circuit 100 controls the drain valve 27 to discharge the dirty washing liquid from the drain pipe 40.

Next, the control circuit 100 performs a dehydration step in which the rotating drum 1 is controlled to rotate at high speed to dehydrate the washing liquid contained in the laundry.

Thereafter, the control circuit 100 controls the water injection valve to inject water into the water tank 2 from the water injection pipeline and perform a rinsing step. At this time, similarly to the washing step, also in the rinsing step, the laundry accommodated in the rotating drum 1 is repeatedly subjected to an agitating operation in which the laundry is lifted and dropped by the agitating protrusion by the rotation of the rotating drum 1 so that the rinsing is performed. Done.

In the case of the drum type laundry dryer according to the present embodiment, the laundry contained in the rotary drum 1 is dried.

Therefore, as described above, the control circuit 100 exhausts the air in the water tank 2 from the circulating air introduction conduit 5, performs dehumidification and heating via the circulating air passages 9 and 11, and again removes the dried air. Control is performed so that air is blown into the water tank 2.

Specifically, the control circuit 100 rotationally drives the blower fan 4 to generate an air flow in the circulation blower paths 9 and 11. Thereby, the moist air in the rotating drum 1 containing the laundry is exhausted from the water tank 2 to the circulating air introduction conduit 5 through the through holes 1a and the like.

Then, the water vapor in the air exhausted to the circulating air introduction pipe 5 is dehumidified by dew condensation by the evaporator 19 located upstream of the blower fan 4. Further, the dehumidified air is heated by exchanging heat in the condenser 17 to obtain dry high-temperature air.

The dried high-temperature air is sent from the blower fan 4 to the circulation airflow paths 9 and 11 from the water tank 2 to be blown into the water tank 2. The high-temperature dry air blown into the water tank 2 is introduced into the rotating drum 1 through the through holes 1 a, escapes to the water tank 2 while being in contact with laundry such as clothes, and is exhausted to the circulating air introduction pipe 5 again. Is done.

That is, the laundry drying step is performed by repeating the circulation of air through the circulation air flow paths 9 and 11 described above.

In addition, when performing a drying step using the circulation ventilation path | routes 9 and 11, foreign materials, such as waste thread generated from laundry, such as clothing, are mixed and circulated in the circulated air. For this reason, foreign matter may interfere with the drying step such as clogging of the evaporator 19 and the condenser 17, biting into the rotating part of the blower fan 4, and deposition on the inner surface of the blower fan 4.

Therefore, the following maintenance is performed to remove foreign matter.

Specifically, in general, a filter for removing foreign matters in the circulating air is provided in the middle of the circulating air passages 9 and 11 (for example, upstream of the evaporator 19, the condenser 17, and the air blowing fan 4). Thereby, the foreign material mixed in the air after drying the laundry is collected by the filter, and is prevented from being mixed into the circulating air blown downstream. As a result, functions such as the evaporator 19, the condenser 17, and the blower fan 4 can be maintained for a long time, and a highly reliable washing machine can be realized.

Hereinafter, the washing machine of the present embodiment and the control circuit of the communication system of the washing machine will be described more specifically with reference to FIG. 3 and FIG.

The first motor 101 corresponds to the motor 3 in FIG. 2 and rotationally drives the rotary drum 1. At this time, the electrical angle of the first motor 101 is detected by three sensors 101a to 101c made of, for example, a Hall IC, which are arranged in the vicinity of the rotor (rotor). The sensors 101a to 101c are arranged on the stator of the first motor 101 so as to face the permanent magnets arranged on the rotor of the first motor 101 at an interval of 120 electrical degrees. The detection outputs of the sensors 101a to 101c are input to the control unit 121.

The control unit 121 controls the first inverter circuit 102 driven by the first inverter driving circuit 103 based on the detection outputs of the input sensors 101a to 101c. Accordingly, the control unit 121 controls the rotation operation such as the rotation speed of the first motor 101 via the first inverter circuit 102.

At this time, the first inverter circuit 102 includes six parallel circuits of switching elements made of, for example, power transistors (IGBTs: Insulated Gate Bipolar Transistors) and reverse conducting diodes. The first inverter circuit 102 includes three sets of series circuits in which two sets of parallel circuits are connected in series. Further, nodes between the switching elements in each series circuit are connected to the U terminal, V terminal, and W terminal of the three-phase winding in the first motor 101, respectively. Thereby, the U terminal, the V terminal, and the W terminal of the first motor 101 are respectively set to three states of positive voltage, zero voltage, and release by a combination of ON / OFF of two switching elements in each series circuit. Can do.

Note that switching of on / off of the switching elements constituting the first inverter circuit 102 is controlled by the control unit 121 and the first inverter drive circuit 103 based on information of detection outputs of the sensors 101a to 101c.

Further, the second motor 111 drives to rotate the compressor 16 in FIG. Then, the control unit 121 controls the rotation operation such as the rotation speed of the second motor 111 via the second inverter drive circuit 113 and the second inverter circuit 112.

At this time, like the first inverter circuit 102, the second inverter circuit 112 includes six sets of parallel circuits of switching elements made of power transistors (IGBT) and reverse conducting diodes. The second inverter circuit 112 is composed of three sets of series circuits by connecting two sets of parallel circuits in series. Furthermore, the nodes between the switching elements in each set of series circuits are connected to the U terminal, V terminal, and W terminal of the three-phase winding in the second motor 111, respectively. Thereby, the U terminal, the V terminal, and the W terminal of the second motor 111 are respectively set to three states of a positive voltage, a zero voltage, and a release by a combination of ON / OFF of two switching elements in each series circuit. Can do.

Further, the current detection unit 114 detects the current output from the three sets of series circuits constituting the second inverter circuit 112. Then, the detection result detected by the current detection unit 114 is input to the control unit 121.

Then, on / off switching of the switching elements constituting the second inverter circuit 112 is controlled by the control unit 121 and the second inverter drive circuit 113 based on the detection result of the current detection unit 114.

Moreover, the temperature detection unit 122 detects the temperature of the refrigerant in the compressor 16 or the pipe line shown in FIG. Note that the temperature of the refrigerant is proportional to the pressure inside the compressor 16. That is, when the pressure in the compressor 16 is high, the refrigerant temperature is high, and when the pressure in the compressor 16 is low, the refrigerant temperature is low.

Further, the load driving unit 132 controls the drying fan 133, the water supply valve 134, and the drain valve 135 based on the control signal of the control unit 121. The drying fan 133 corresponds to the blower fan 4 shown in FIG. 2, and allows the dry hot air generated in the heat exchange unit 18 including the compressor 16 to flow into the water tank 2. The water supply valve 134 is disposed on the water supply pipe and supplies water to the water tank 2.

The control unit 121 also includes information on the current value of the second inverter circuit 112 that rotationally drives the compressor 16 detected by the current detection unit 114 and information on the refrigerant temperature in the compressor 16 detected by the temperature detection unit 122. And pulses detected by the sensors 101a to 101c are input. At this time, the control unit 121 detects the rotation period of the first motor 101 based on the pulses input from the sensors 101a to 101c. Further, the control unit 121 calculates the rotation speed of the first motor 101 based on the detected rotation cycle. Then, the control unit 121 controls the output of the first inverter circuit 102 via the first inverter drive circuit 103 so that the rotation speed of the first motor 101 becomes the calculated rotation speed. Similarly, the control unit 121 sets the second inverter drive circuit 113 and the second inverter based on the input current value information of the second inverter circuit 112 and the refrigerant temperature information in the compressor 16. The rotation of the second motor 111 is controlled via the circuit 112.

Further, as shown in FIG. 3, the control unit 121 further includes a memory 51 and a rewriting unit 52 that rewrites the setting contents stored in the memory 51.

If there is, the rewriting unit 52 of the control unit 121 rewrites the setting content of the memory 51 of the control unit 121 to the data of “favorite driving course” based on the received signal.

In addition, the signal transmitted / received should just contain at least 1 of the washing time for washing operation, the amount of water, dehydration time, or drying time, for example. Based on the received signal, the rewriting unit 52 of the control unit 121 rewrites the setting content stored in the memory 51, at least one of the washing time, the amount of water, the dehydration time, and the drying time for the washing operation.

S7).

Next, the rewriting unit 52 of the control unit 121 sets the washing operation of the original driving course stored in the memory 51 based on the signal of the setting contents of the washing operation of the “favorite course” received by the transmission / reception unit 230. The contents are rewritten with the data of the setting contents of “favorite course” (step S8), and the process returns to step S2.

On the other hand, when the portable information terminal 220 is not used (NO in step S3), the user changes the setting content of “favorite course” with the setting button of the operation unit 8A of the washing machine main body 210 (step S5).

Next, the rewriting unit 52 of the control unit 121 changes the setting contents of the original driving course stored in the memory 51 in advance based on the washing driving setting contents of the “favorite course” changed through the operation unit 8A. The data is rewritten with the data set for “favorite course” (step S6), and the process returns to step S2.

Then, based on the driving course set by data communication via the portable information terminal 220 or input by the operation unit 8A, a sequence for executing the washing operation is started and the washing operation is executed. Thereafter, when the sequence of the washing operation is completed, the washing operation is completed.
