Description

  The present invention automatically detects the amount of laundry, and automatically puts an amount of detergent suitable for the amount of laundry into the tub, thereby eliminating waste of the detergent and realizing a washing time suitable for the laundry. The present invention relates to a washing machine having the following function.

  What is currently mainstream is that the user measures the detergent, puts it in the detergent case, and puts the detergent into the washing tub or the water tank located around it by supplying water for washing It is. The method of measuring the amount of the detergent is to measure with the measuring spoon attached to the detergent. The amount of laundry, such as 0.6 cup of measuring spoon, is put in the detergent case. is there.

  Therefore, after the user puts the laundry in the washing tub, the power is turned on, and after starting, the amount of laundry is automatically detected, the amount of detergent suitable for the amount of laundry is displayed, and the detergent case is displayed to the user. Will be put in. Thereafter, water is supplied for washing, the water is poured into the detergent case with the water, and the water is put into the water tank together with the detergent. At that time, a proposal has been made to prevent the detergent from remaining by vibrating the detergent case and collecting the detergent in a part (see, for example, Patent Document 2).

  In addition, in order to carry out washing twice, a proposal has been made to put a detergent for a different purpose of use. For example, in addition to the detergent case, a case is used in which a soft finish is placed, and the detergent is put therein to realize washing twice (see, for example, Patent Document 1).

  In addition, a product has been proposed in which a portion where a liquid detergent bottle can be attached to the washing machine is provided exclusively, and the amount of the liquid detergent is calculated based on the opening and closing time of the valve.

JP 2013-135712 A JP 2011-083466 A

  However, these conventional technologies are based on the premise that the user puts the amount of the detergent in the amount of detergent, and the accuracy is left to the user, the usability is poor, and the washing time is optimal. It is difficult to make water, and waste of water and detergent may occur.

  In the conventional technique shown in the above-mentioned Patent Document 1, when the dirt is severe or the user wants to wash twice in succession, the detergent is put into the soft finish container in addition to the present detergent container. Proposals have been made, but there are situations where the user has to weigh the amount of detergent into each case, and when the detergent is put in, the detergent may not be poured into the water tank cleanly depending on how the detergent is put in. And the detergent is mixed with the soft finish on the next use. In such a state, there is a possibility that the detergent remains attached to the laundry, resulting in a malfunction.

  Further, the conventional technique disclosed in Patent Document 2 has two major problems.

  The first problem is that the user must weigh and put the detergent as before. Even if the amount of laundry is detected by the washing machine and the optimum amount is displayed, it is very difficult to accurately measure 0.6 cups of the measuring spoon when the display itself is, for example, 0.6 cups. .

  In addition, after the user puts the laundry into the washing machine and presses the start button and waits for several seconds to about ten or more seconds, the measurement of the amount of laundry is finished and displayed. Until the amount of laundry is displayed, the user waits in front of the washing machine, which is inconvenient for the user. If you do not want to wait for the display time, the amount of detergent should be added according to the amount of laundry, but there are few users who can see the weight of the laundry by looking at the laundry. It is assumed that the optimal amount of detergent cannot be selected.

  Therefore, it is difficult to accurately measure the amount of detergent with respect to the laundry, and the timing at which the detergent is put in is also inconvenient for the user.

  The second challenge is to stabilize the pouring of the water supply by vibrating the detergent case that contains the detergent to make it part of the solution. However, depending on the vibration noise and operating time caused by the vibration, the user may feel uncomfortable. May give. In addition, when washing is performed continuously, the inner surface of the detergent case is not completely dry, and depending on how the user puts the detergent, the detergent adheres to the wall surface and may not drop due to vibration.

  In addition to Patent Documents 1 and 2, there is also proposed a product in which a liquid detergent set in advance is automatically put in an optimum amount according to the amount of laundry. The amount of laundry detergent is measured by the operating time of the pump, but the optimal amount of detergent varies greatly depending on the ambient temperature, the type of detergent, the remaining amount, the viscosity, etc., and the detergent depends on the operating time of the pump. Even if the amount is controlled, the optimal amount cannot be measured, and the liquid detergent remains in the charging path and sticks, which may cause mold and the like, which may cause discomfort to the user. There could be no situation.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a washing machine that can be washed with an appropriate wire material without a user measuring the amount of detergent.

The following description is one specific example of the present invention, and the present invention is not limited to this embodiment.

(Embodiment 1)
About the washing machine of this Embodiment, the whole operation | movement outline | summary and the structure of each means, operation | movement, and an effect | action are demonstrated using a drum type washing machine.

  1 is a cross-sectional view showing a schematic structure of a drum type washing machine according to an embodiment of the present invention, FIG. 2 is a partial fragmentary sectional view showing a configuration of a solid detergent discharging portion of the drum type washing machine, and FIG. (A) is sectional drawing of the circulation pump used for the drum type washing machine, FIG.3 (b) is a side view of the circulation pump, FIG.4 (a) is the principal part of the water tank of the drum type washing machine. FIG. 4B is a plan view of the main part and cover of the water tank, FIG. 5A is a cross-sectional view of a water circulation path of the water circulation path of the drum-type washing machine, and FIG. Sectional drawing which shows the discharge outlet vicinity of the water circulation path | route, FIG.5 (c) is an expanded sectional view of the cyclic | annular exit vicinity of the water circulation path | route.

In accordance with the mode setting and control program, the motor (rotary drum driving means) 6, the water supply system (water supply path) 7, the drainage system (drainage path) 8, the drying system 9, the solid detergent discharge unit 15 and the like shown in FIG. Thus, a so-called drum type washing and drying machine having a function of performing at least a washing process, a rinsing process, a dehydrating process, and a drying process is configured. However, the drying system 9 may be omitted and a so-called drum type washing machine may be used. In addition, in addition to the above, the water in the water tank 3 is circulated in the water circulation system (water circulation path) 16 as necessary during the washing preparation process, the washing process, the rinsing process, etc. It also has a function to prevent and improve functions of washing and rinsing.

  The water supply system 7 can supply water in a timely manner by opening and closing a water supply valve 10 which is an electromagnetic valve, and the water tank 3 is supplied from the solid detergent discharge unit 15 (see FIG. 6) including the discharge means 200 using the water supply. It can be inserted in a timely manner. Further, the water supply system 7 and the discharge means 200 are communicated with each other via a discharge means water supply valve 205. The drainage system 8 can be drained when necessary, such as at the end of the washing process or at the end of the rinsing process, by opening and closing the drain valve 19. The water circulation system 16 repeatedly sucks the water in the water tank 3 with the circulation pump 20 and returns it to the water tank 3.

  The mode such as the driving course and various functions are selected by inputting from the operation panel 21 provided in the upper front portion of the washing machine body 2, and the control means 22 displays the display means on the operation panel 21 based on the input information. Then, when the start of operation is set by the input setting means on the operation panel 21, data is input from a water level detection means (not shown) for detecting the water level in the aquarium 3, etc. Starting, the operation of the drain valve 19 and the water supply valve 10 is controlled, and operations such as washing, dehydration, and drying are performed. The washing machine body 2 is provided with an opening / closing door 5, and the opening / closing door 5 is hermetically sealed through a sealing material 14 attached to the rim of the opening 13 of the water tub 3 and can be opened. .

  Note that the washing tub 4 (hereinafter referred to as the rotating drum 4) is driven by the motor 6 around the rotating shaft 4a, and the rotating drum 4 has a sudden forward arc rotation and a sudden reverse arc exceeding 90 degrees and less than 180 degrees. The forward / reverse arc rotation drive mode in which the rotation is repeated alternately and the continuous rotation of the rotating drum 4 at a rotating speed indicating the behavior in which the laundry lifted by the rotation of the rotating drum 4 falls from the height where its own weight wins alternately Forward / reverse continuous rotation drive mode, and repeatedly executing the forward / reverse arc rotation drive mode and the forward / reverse continuous rotation drive mode in a washing process or a washing process and a rinsing process, or either Only one of them can be executed.

  As a result, the laundry is lifted up to more than 90 degrees and less than 180 degrees by the arc rotation and rapid braking of the rotating drum 4 at a rapid speed of more than 90 degrees and less than 180 degrees. Since the braking state is caused by the sudden braking in the final stage, the laundry can be reliably peeled off from the inner surface of the rotating drum 4 by its inertia and its own weight and dropped to the side opposite to the lifting side by its own weight. Therefore, it is possible to improve the washing performance because the laundry is sufficiently swollen, loosened and slippery with a particularly high unraveling action and can exert mechanical force on the laundry.

  Furthermore, by performing the forward / reverse arc rotation drive mode by alternately repeating the forward / reverse rapid arc rotation of the arc rotation drive in the forward direction and the reverse sudden arc rotation in the reverse direction, As the lifting position and falling position of the garment are alternately switched to the left and right in each arc rotation drive, it is possible to further improve the solving action while preventing the laundry from becoming entangled and to increase the number of times that the mechanical force is exerted on the laundry. Therefore, the cleaning performance can be improved.

  In addition, because of the high unraveling action, it is possible to suppress the entanglement of the laundry caused by the progress of the washing and rinsing process, so that effective tapping washing in the forward / reverse arc rotation drive mode is continuously executed, and the washing effect And the rinsing effect can be enhanced.

  Further, in the forward / reverse arc rotation drive mode alone, the tangling, twisting, wrinkles, etc. of the laundry are reduced, but the vertical position of the laundry is difficult to change, and the laundry at the bottom of the rotating drum 4 is difficult to move. The unevenness of washing is likely to occur, but by using the forward / reverse continuous rotation drive mode in combination, it is possible to change the position of the laundry in the vertical direction.

  In other words, the tangling, twisting, and wrinkling of the laundry in the forward / reverse continuous rotation drive mode is reduced, and the imbalance in applying mechanical force to the laundry in the forward / reverse arc rotation drive mode is reduced, thereby facilitating washing in both modes. Two different behaviors can be imparted to the laundry being rinsed. Specifically, depending on the forward / reverse arc rotation drive mode, it can give a firm hand-washing behavior while reducing tangling, twisting, and wrinkle of the laundry, and the forward / reverse continuous rotation drive mode makes the laundry larger. It can be moved continuously and washed with less unevenness, giving it an effective washing behavior against uniform and strong dirt.

  The circulation pump 20 is fixed to the base plate 2a, and the discharge side path 16b from the circulation pump 20 of the water circulation system 16 extends toward the front side of the washing machine body 2 where the opening 13 of the water tank 3 is located. It is supposed to be. Specifically, as shown in FIGS. 3 (a) and 3 (b), the circulation pump 20 has a resin-made pump casing 20b containing the impeller 20a on the opening side of the front end of the motor casing 20d of the circulation motor 20c. The impeller 20a is directly connected to the motor shaft 20e, and is fitted to a resin mounting seat 35.

  Moreover, the discharge side path | route 16b of the water circulation system 16 is the connection part shown to Fig.4 (a) provided in the lower part vicinity of the front end wall 3h around the opening 13 of the water tank 3, as shown in FIG.1, FIG.4, FIG.5. 4 and provided on the front end wall 3h of the water tank 3, the rear surface of the bulging portion 3a shown in FIGS. 4 (a) and 5 (a), and the water tank 3 shown in FIGS. 4 (b) and 5 (a). The front end wall 3h communicates with a water conduit 55b constituted by a back surface of a cover 55 attached by fastening screws with the packing 55a. As shown in FIG. 5B, a part of the cover 55 has a notch portion 55c having no sealing structure including a packing 55a, and the notch portion 55c and the front end wall 3h of the water tank 3 corresponding to the notch portion 55c. The discharge port 55d having an opening corresponding to the circumferential direction region is formed between the rear surface of the first and second surfaces.

  The washing water pressurized by the circulation pump 20 flows into the water conduit 55b from the connecting portion 51 via the discharge side path 16b of the water circulation system 16, and corresponds to the back surface of the front end wall 3h of the water tank 3 from the discharge port 55d. Washing water is sprayed between the front end wall 4b of the rotating drum 4 and discharged into the rotating drum 4 through a flow path 52 formed therebetween. As shown in FIG. 5 (b), the discharge port 55 d is located on the back surface of the front end wall 3 h of the water tank 3, and specifically between the front end walls 3 h and 4 b of the water tank 3 and the rotary drum 4. It opens toward the annular outlet 53 in the channel 52. As a result, the circulating water ejected from the discharge port 55d is efficiently discharged from the flow path 52 toward the rotation center side of the rotary drum 4, specifically, toward the annular outlet 53 in the radial direction inside the rotary drum 4. The circulating water can be efficiently supplied regardless of the amount of laundry.

  In particular, the front end wall 3h of the water tank 3 has an inclined surface 3h1 inclined toward the rear side of the washing machine body 2 from a position corresponding to the discharge port 55d toward the inner periphery, and the rotating drum 4 from the inclined surface 3h1 to the inner periphery. The curved surface 3h2 is curved toward the opening 54 side. As a result, the circulating water ejected into the flow path 52 extends along the curved surface 3h2 from the inclined surface 3h1 to the rear side of the rotating drum 4 through the opening 54 of the rotating drum 4 as shown in FIG. The efficiency of supplying circulating water to laundry can be increased.

Further, the cleaning water is stably discharged into the rotating drum 4 from the predetermined region corresponding to the circumferential direction region of the discharge port 55d of the annular outlet 53 to the left and right in a predetermined direction, and the inclined surface 3h1 and the inclined surface 3h1. From the surface 3h1 to the inner periphery, it flows along the curved surface 3h2 curved toward the opening 54 side of the rotary drum 4. For this reason, the washing water is guided without disturbance by the curved surface 3h2 configured in an annular shape, and spreads in a predetermined direction from a predetermined area in the circumferential direction corresponding to the discharge port 55d of the annular outlet 53 into a substantially fan shape. The washing water can be discharged stably, and the washing water can be effectively sprayed on the laundry in the rotating drum 4 regardless of the amount.

  As a result, the discharge port 55d of the washing water from the discharge side path 16b is in a position where it does not come into contact with the laundry in the rotating drum 4, so that the laundry is caught and washed too easily and disturbs the behavior necessary for drying and the like. Or the laundry can be prevented from being damaged or torn, and the appearance is not impaired. The effect of circulating water injection is further enhanced by the combination of the effect of the laundry behavior that changes up and down in the forward / reverse continuous rotation drive mode and the effect of the laundry behavior that changes left and right in the forward / reverse arc rotation drive mode. .

  The upstream side of the circulation pump 20 in the water circulation system 16 communicates the suction side path 16 a from the drain outlet 8 a at the bottom in the water tank 3 to the suction port of the circulation pump 20 through the filter 56. Here, the filter 56 prevents relatively large lint from clothes and the like from entering the circulation pump 20, and is caught, accumulated, or bitten by the circulation pump 20, thereby circulating water. The clogging, damage and breakage of the system 16 are avoided, and the yarn waste is prevented from circulating and reattaching to the rotary drum 4 again. The filter 56 can be easily maintained by the user as appropriate, and can ensure the safety and stability of the circulation operation for a long time.

  Next, the configuration, operation, and action related to the discharge of the solid detergent 204 to the rotating drum 4 or the water tank 3 will be described.

  FIG. 6 is a perspective view showing the configuration of the solid detergent discharge portion of the drum type washing machine according to the embodiment of the present invention, and FIG. 7 shows the discharge means, the storage case, and the solid form of the solid detergent discharge portion of the drum type washing machine. FIG. 8 is a control block diagram of the solid detergent discharging operation of the drum type washing machine.

  First, the discharge means 200 can be driven / stopped by the control means 22. Here, the discharge means 200 can be easily controlled by using a stepping motor or the like that can control the rotation angle. Further, the water supply of the water supply system 7 is also controlled by the control means 22. The water supply system 7 supplies water to the water tank 3 through the solid detergent discharge unit 15 having a partial discharge means 200 as necessary.

  In the case of fixed detergents, for example, the pattern of the amount of the conventional detergent used in the measuring spoon is 0.2, 0.4, 0.6, 0.8, 1 and so on. Suppose there was. In this case, since the amount of detergent in a small amount becomes 0.2 cups, at most 0.1 detergent is equivalent to one solid of the solid detergent 204 in the present embodiment (see FIG. 12). . The storage case 203 stores 20 solid detergents 204.

  First, the relationship between the storage case 203 and the discharge means 200 is as shown in FIG. That is, the storage case 203 is loaded with the solid detergent 204 from above, and the discharge means 200 closes the movement hole 203a of the storage case 203 so that the solid detergent 204 does not fall downward. At the same time, the transport port 3 b of the solid detergent 204 to the water tank 3 is closed by the discharge means 200. Fig.7 (a)-FIG.7 (c) are the figures which have shown the positional relationship in two dimensions.

  A flow in which the solid detergent 204 is carried into the water tank 3 will be described with reference to FIGS. 6 and 7A to 7C.

  The bottom surface of the storage case 203 in which 20 of the solid detergents 204 are stored is a moving hole 203a. The discharge means 200 is arranged close to the lower position of the moving hole 203a. The discharge means 200 is a rotation type that can rotate around the central axis, and has one or more notches 200a and one or more stoppers 200b (in this embodiment, the notches 200a and the stoppers). The four 200b are alternately arranged on the circumference.)

  The dimensions of the notch 200a are, for example, the width, depth, and height of the solid detergent 204 are W2, D2, and L2, respectively, and the width, depth, and height of the notch 200a of the discharging means 200 are W1, D1, and L1, respectively. , W2 <W1, D2 <D1, L2> L1. The height L is set so that the discharge means 200 does not hit the stopper 200b rotated to the lower position of the solid detergent 204 by the rotation of the discharge means 200 when the solid detergent 204 positioned at the lowermost position is stored in the cutout 200a. I have to. This is because the stopper 200b closes the moving hole 203a of the storage case 203 when the stopper 200b rotates to a position below the storage case 203. When the notch 200a is positioned below the moving hole 203a of the storage case 203, the solid detergent 204 moves into the notch 200a, and when the stopper 200b is positioned below the moving hole 203a, the storage case is moved by the stopper 200b. The solid detergent 204 in 203 is held so as not to drop from the movement hole 203a.

  As shown in FIG. 7A, when the solid detergent 204 is stored in the notch 200a, the stored solid detergent 204 is moved from the right side to the left side in FIG. Move to.

  Then, as shown in FIG. 7B, in the state where the solid detergent 204 stored in the notch 200a supports the next solid detergent 204 in the storage case 203, below the next solid detergent 204, The next stopper 200b rotates. When the discharging means 200 further rotates, as shown in FIG. 7C, the next solid detergent 204 is stored in the notch 200a.

  The solid detergent 204 accommodated in the notch 200a of the discharging means 200 moves to the conveyance port 3b to the water tank 3, and the conveyance of one solid detergent 204 into the water tank 3 is completed.

  Here, another characteristic configuration of the solid detergent discharging unit 15 of the drum type washing machine according to the present embodiment will be described.

  As shown in FIG.7 (c), as for the conveyance port 3b, the front-end | tip part is connected to the water tub 3, and there exists a possibility that water and a detergent may jump by the influence of the position or rotation of the laundry in a tub. is there. Therefore, in a state where the movement hole 203a of the storage case 203 is closed with the stopper 200b so as to be a cover for splashing water or detergent, the transport port 3b to the water tank 3 is simultaneously closed with the next stopper 200b, and the inside of the discharge means 200 In addition, water, detergent, foam, etc. prevent entry.

  For example, although it has been described earlier that the discharge means 200 has one or more notches 200a, in the case of one notch 200a, the above-described operation is performed. When the four cutouts 200a are provided and the conveyance port 3b to the water tank 3 is arranged at a position diagonal to the storage case 203, the inside of the discharge means 200 is in a state where one is conveyed from the conveyance port 3b to the water tank 3. Two solid detergents 204 are stored in the. That is, in a state where the solid detergent 204 is conveyed from the conveyance port 3b to the water tank 3, the amount of the solid detergent 204 that is ½ of the number of the notches 200a is stored in the notch 200a.

As described above, since the amount per one of the solid detergent 204 is set to 0.1 cup of the measuring spoon of the detergent, if the amount of the detergent corresponding to the amount of the laundry is 0.4 cup, the operation described above is performed. Will be continued 3 times. By this operation, a delicate amount of 0.4 cup can be put into the water tank 3 with high accuracy.

  In the present embodiment, the shape of the solid detergent 204 is a rectangular parallelepiped as shown in FIGS. 6 and 7, but may be other shapes. For example, in the case of a configuration in which the friction with the surrounding storage case 203 is small, such as a spherical configuration, it is more likely to fall into the notch 200a of the discharge means 200. The solid detergent 204 is less likely to be scraped by friction with the surroundings. Thus, it is preferable that the storage case 203 and the solid detergent 204 have a smaller contact surface.

  Next, the operation and action of the control means 22 will be described based on the control block diagram shown in FIG.

  When the control means 22 detects the amount of laundry and recognizes that the amount of detergent relative to the amount of laundry is, for example, 0.4 cups, it sends a signal to the motor 6 which is a drive means for driving the discharge means 200. send. In this embodiment, the motor 6 uses a stepping motor. The state until the control unit 22 sends a signal is a state where the solid detergent 204 in the storage case 203 is held at the position of the movement hole 203a by the stopper 200b of the discharge unit 200 (the state shown in FIG. 7C).

  When the control means 22 outputs a signal to the discharge means 200, the discharge means 200 starts rotating as described above. In accordance with the rotation, the notches 200a and the stoppers 200b in the discharging means 200 are alternately moved to the lower part of the moving hole 203a of the storage case 203. When the notch 200a is positioned below the storage case 203, the solid detergent 204 falling from the moving hole 203a is stored in the notch 200a, and when the stopper 200b is positioned below the storage case 203. The moving hole 203a is blocked by the stopper 200b. For example, if the notch 200a of the discharging means 200 is four, the control means 22 rotates four rounds (360 degrees) to drop the four solid detergents 204 into the transport port 3b transported to the water tank 3. Can be made.

  Further, the control means 22 having the configuration of the control block diagram shown in FIG. 9 supplies the powder of the solid detergent 204 remaining in the notch 200a of the discharging means 200 after the solid detergent 204 has been transported. The discharge means water supply valve 205 (solid detergent water supply valve) is operated together with the water supply system 7 in order to flow into the water tank 3 using the water supply of the washing water 7. Thus, the water supply valve 10 is normally operated to open the discharge means water supply valve 205 in addition to the path of water supply into the water tank 3 by the water supply system 7, so that the discharge means 200 has the required number of solids. Water is supplied at a timing when the detergent 204 has been transported, water is discharged into the water tank 3 from the transport port 3b, and powder of the solid detergent 204 is poured into the water tank 3.

  FIG. 10 shows a timing chart of the operation at this time. In FIG. 10, when the discharge means 200 has four cutouts 200a, the discharge means 200 can store the solid detergent 204 in the cutouts 200a and can be transferred to the water tank 3 from the transfer port 3b. In this case, it is the timing when the third one is stored (<A> timing in FIG. 10).

  Thereafter, the timing at which the four solid detergents 204 are finished is <B>, and the control means 22 once stops the operation of the discharging means 200 at that timing. At this time, the discharge means 200 is fixed, and the position of the discharge means 200 is in a state where the notch 200a and the transport port 3b to the water tank 3 overlap and face each other (the state of FIG. 7A).

During the operation of the discharging means 200 or when the solid detergent 204 is stored in the cutout 200a from the storage case 203, a portion of the solid detergent 204 may be scraped, and the detergent powder may be present in the cutout 200a. . The control means 22 executes an operation for cleanly pouring away the detergent powder or the like of the notch 200a at the timing <B> described above. In this state, as described above, the discharge means water supply valve 205 and the water supply system 7 are operated to perform a series of operations for supplying water into the water tank 3. By this water supply operation, detergent powder or the like adhering to the notch 200a of the discharging means 200 can be poured out.

  Thereafter, the valve of the discharge means water supply valve 205 is closed at timing <C>, and the movement operation of the discharge means 200 is performed by 45 degrees so that the stopper 200b comes below the movement hole 203a of the storage case 203 (FIG. 7 ( c)).

  Moreover, since the washing machine handles water, there is a possibility that the solid detergent 204 may absorb moisture due to humidity. When the solid detergent 204 absorbs moisture, problems such as poor sliding of the solid detergent 204 in the storage case 203, increased viscosity of the overlapping portion, and chipping tend to occur. Therefore, it is preferable that the storage case 203 has a certain temperature and can always dehumidify the solid detergent 204. For this purpose, a solid detergent heater 206 (heater) is provided as in the control block diagram shown in FIG. 11, and the control means 22 operates the solid detergent heater 206. For example, a heater capable of maintaining about 40 ° C. with a low capacity of about 5 W is provided to dehumidify the solid detergent 204. The solid detergent heater 206 is disposed around a storage case 203 in which the solid detergent 204 is stored.

  Furthermore, according to the drum type washing machine having the above-described configuration, the solid detergent 204 can be automatically put into the water tub 3 at a desired timing, and the user wants to wash the laundry with terrible dirt twice in a row. In the case of the conventional configuration, the detergent can be set only once for one place in the conventional configuration. However, in the configuration of the present embodiment, the detergent for a plurality of times is provided. The number of washings can be freely selected by being set at a time.

  For example, by selecting a setting that allows multiple washings on the operation panel 21, the control unit 22 automatically controls the operation of each load such as the motor 6, the water supply system 7, the drainage system 8, and the discharge unit 200. You will be able to do two washes. At the time of washing, washing can be performed automatically by adding an appropriate amount of detergent each time. Here, with regard to the amount of detergent, when a plurality of washings are performed in succession, the amount of dirt is the second time even if the amount is less than the second amount with respect to the amount of detergent for the first washing. Since it is less than the first time, the same effect can be obtained, and washing time can be shortened by reducing the amount of detergent, so the amount of detergent may be set to an amount as shown in FIG. 13, for example. .

  As described above, since the washing machine according to the present invention can be automatically and accurately executed when the detergent is introduced, it can be used for various types of washing machines for home use, and also for business-use cleaning equipment. Is available.
