DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a dishwashing machine for washing tableware, and more particularly relates to a process that can make the necessary travels generally The operation mode and the dishwashing machine that operates in the silent operation mode that is quieter than the normal operation mode. [Prior Art 1 Background of the Invention 10 The dishwashing machine generates washing noise when washing dishes or when washing, and the user feels uncomfortable with the washing noise. In order to reduce the noise of the cleaning, various dishwashing machines having a cleaning program capable of reducing the washing noise have been developed. A conventional dishwashing machine which can reduce the washing noise is disclosed in Japanese Laid-Open Patent Publication No. 2000-316779. The dish washer has a low-pressure washing program for lowering the injection pressure of the washing water sprayed from the nozzle holes and washing the tableware. In the low pressure washing program, the injection pressure of one of the washing strokes is made higher than the injection pressure during the flushing stroke. Thereby, the washing noise in the washing stroke can be made lower than the washing noise in the general washing program. In the conventional dishwashing machine, since the jetting pressure during the washing stroke is lowered, when the washing time is not longer than the washing time in the normal washing program, a sufficient washing effect cannot be obtained. Japanese Laid-Open Patent Publication No. Hei 6-7282 discloses a conventional dishwashing machine which can reduce the washing noise. In the dishwasher, when the washing water is supplied to the washing pump of the nozzle, the starter is raised to a predetermined output to perform the washing operation, and thus the washing pump is controlled. The output. These conventional dishwashing machines can reduce the arpeggio that is exhibited when the washing water from the nozzle is sprayed during the washing stroke or the flushing stroke. However, when the washing water after the washing or the flushing stroke is discharged, the noise generated by the drain pump or the noise generated by the washing water and the air simultaneously entering the drain pump may occur. These dishwashing machines cannot reduce the noise. A conventional dishwashing machine disclosed in Japanese Laid-Open Patent Publication No. 2000-316779 has a plurality of nozzles. In order to supply the washing water to the plurality of nozzles by the washing pump, the dish washing machine has a water dividing mechanism provided in the flowing water line. Other conventional dishwashing machines having such a force water mechanism are disclosed in Japanese Laid-Open Patent Publication No. 2004-275365. The water dividing mechanism is constituted by a switching valve having a closing member provided with a cam mechanism. The °H switching valve has: a washing water that has been pressurized by a washing pump, and the introduced washing water is led to the plurality of outlets of the plurality of nozzles, the outlet, the outlet of the water outlet, and the passage The water portion intermittently rotates and sequentially blocks the occluding members of the outlet. The occluding member is provided with a cam mechanism, and the cam mechanism reciprocates between the inlet and the outlet, and is rotated by a predetermined angle toward the unidirectional motion in conjunction with the reciprocating motion. The water flow path associated with the plurality of nozzles can be selectively switched in sequence by the reciprocating motion of the blocking member and the rotary motion of the cam mechanism accompanying the reciprocating motion, and the plurality of nozzles are sprayed and pressurized by a washing pump. Clean water. 6 200847986 In the dish washer, the washing water can be sprayed from the counter nozzle to set the discharge pressure of the washing water to be low to reduce noise. However, when the blocking member of the switching valve is reciprocating to switch the flow path of the washing water, the blocking member collides with the member of the outlet to generate a large noise. [Explanation] SUMMARY OF THE INVENTION A dishwashing machine includes: a washing tank configured to receive a washing; and a washing pump for supplying washing water for washing the washing to the washing a drainer; a drain pump that discharges the wash water supplied to the ten washing tanks from the washing tank; and a control device that drives the washing pump and the drain pump, and the control device is switchable And a normal operation mode and a silent operation mode for reducing noise generated by the normal operation mode, and operating to drive at least one of the cleaning pump and the drain pump. 15 The dishwasher can reduce the noise generated.

The knife water device 50 has a valve body 51 and a valve chamber 58 in which the valve body 51 is housed. The valve body 51 is rotated about the suspect shaft 51A, and is sent to the water dividing paths 52, 53, 54 in the order of washing or cleaning, by the water supply brothers. The water passages 52, 53, 54 are connected to the upper space 5GA of the water dividing device 50. The upper two 50A (3) have a water inlet 57. The sub-watermark is provided with knife water openings 57Α to 57D which are opposite to the valve body 51. The water dividing opening 57 is connected to the water path 52 which is similar to the washing nozzle. The water dividing opening 57 is connected to the water dividing path 1〇 53 connected to the nozzle 42. The water dividing opening 57C communicates with the water dividing passage 54 connected to the nozzles 43, 44. The water dividing opening 57D is connected to the water dividing path connected to the nozzle 41 and the nozzle is connected to the K path 53. The water dividing openings 57 to 57d are arranged at an angle of 90 degrees around the rotation 姊a. 51 is moved in the chamber 58 in response to the water pressure of the washing water in the form of the washing branch 4. The valve body 51 is in contact with the water dividing position of the water dividing port 57 in response to the water pressure, and is away from the water dividing port 57. The movement between the non-water-distributing positions. As shown in the figure _, the valve body 51 has a notch portion ΐβ. When the valve is located at the water-distributing position, three of the water-dividing openings MID are blocked and the notch is open and the water is opened n57A. The remaining ones in ~57D. By this, the washing water is not sent to the water-dissipating heart 57A~5 which is blocked by the coffee 1 and 3 of them, and: 1 to the lack of _, the release of the singer ~ 5 view of which 1 (4) In the non-knife position, the valve body 51 will not block any of the water separation openings 57 57D. In the valve chamber 58, the dragon 51 is between the water separation position and the non-water separation position to 20 200847986 The upper cam mechanism 61 and the lower cam mechanism 62 alternately move between the return movements to rotate the valve body 51 about the rotation shaft 51A, thereby changing the angle of the valve body 51. The lower cam mechanism 62 is constituted by serrated cams 61A and 61B that are engaged with each other. The ore-shaped cams 61 a and 61B hold the valve body 51 at four angular positions set at an interval of 90 degrees, and The upper cam mechanism 61 is composed of a mountain cam 62A and a rib cam 62B that radially extends from the rotating shaft 51A. The mountain cam 62A is provided in the valve body 51 and faces the water dividing port 57. The rib cam 62B can also be used as a partition wall that partitions the water dividing port 57 into the water openings 57A to 57D. 10 The operation of the water dividing device 5 。. The valve body 51 held by the lower cam mechanism 62 and located at the non-water dividing position is used. The water is pushed up by the water pressure of the washing water supplied through the water supply path 56, moved to the water dividing position, and abuts against the water dividing port 57. At this time, the inclined surface 162A of the mountain cam 62A abuts against the rib cam 62B, And the valve body 51 is rotated about the rotating shaft 51A at an angle A1 greater than 0 and less than 90. When the 15 valve body 51 abuts against the water dividing port 57, three of the water dividing openings 57A to 57D are blocked, and the remaining One is opened in the notch 51B. It is sent through the water supply path 56. When the water pressure of the washing water becomes low or the washing water is not delivered, the valve body 51 will fall and move to the water dividing position, and the lower cam mechanism 62 surrounds only the angle A2 which is larger than 〇 less than 90°. The rotation shaft 51A rotates. The angle a is the sum of A2 and 90. That is, the 20 valve body 51 is held by the lower cam mechanism 62, and is made between the non-water-distributing position and the water-dividing position abutting the water-splitting port 57. When going back and forth, it will rotate 90 around the rotating shaft 51A. As a result, the valve body 51 will open the water dividing openings 57A to 57D one by one, and the brigade will block the remaining water dividing openings of the opened water dividing opening. Therefore, with the water dividing device, the washing water sent by the washing pump 6 will send 12 200847986 to the nozzle 4i without being sent to the nozzles, and then will not be sent to the nozzles 43, 44, the German ^ to 1 nozzles 41, 42 nozzles 4, 43, 44, narrowly, and 曰 transported to the nozzle 42 without being sent to the crucible. Then, the same /, 44 is not sent to the nozzle 4 5 5 15 15 20 to be ejected. In this order, the nozzles 41 to 44 are switched and the washing water is sent out as shown in Fig. 3, and the elastic member 63 51 faces the surface 57. The elastic braid is composed of polytetrafluoroethylene and a highly water-resistant material.

In other words, the control unit 10 is operated and the operation mode is changed, and the private operation is switched between the normal operation mode and the monthly operation mode, and at least one of the cleaning pump 4 and the drain pump 6 is driven to operate. 5 brother Ming tableware washing machine 1001 action. Fig. 5 shows the dishwashing machine. Operation 4 Washing machine 1 〇 〇 1 is performed in the order of the washing stroke, the flushing stroke and the drying stroke. In the dish washer 1001 of the embodiment, the washing step 1 is performed once during the washing course, and the draining step S2 is performed after the washing step S1. In the washing step S1, the washing liquid mixed with the lotion is sprayed from the spray holes 41Α to 44A of the nozzles 41 to 44 to the laundry such as dishes to wash the washed matter. At this time, the control device 12 can also drive the heater 5 to heat the washing water. The washing water after the washing is washed out to the outside of the casing 1 by the drain pump 6 via the drain path 59 in the 20 draining step. After the washing step 100 of the washing course, the washing machine 1001 performs the normal temperature washing steps S3, S5, and S7 three times, and the draining steps 84 and S6 after the normal temperature washing steps S3, S5, and S7. S8. Normal temperature rinsing 14 200847986 In step S3, S5, s + /, the washing water not mixed with the lotion will be sprayed by the nozzles 41~f; the object is used to rinse the washings. At this time, the control device 12 does not heat the washing water by adding, Γ, or Γ. After the normal temperature washing steps S3, S5, and S7, the washing water is discharged by the drain pump 6 through the drain path 59 in the draining steps S4, S6, and S8, and is discharged to the outside of the casing 1. The dish washing machine 1001, after the draining step S8, performs a washing step S9 and a draining step S10. The heating and rinsing step S9 and the washing water not having the lotion are sprayed onto the washings by the nozzles 41 to 44 to rinse the washings. The control unit 12 heats the washing water by the heater 5. After heating and diluting a ...' v ^ S9, the washing water is discharged to the outside of the casing 1 through the drain path by the drain pump 106 in the draining step si. The four washing machines 1〇〇1 perform the drying step S11 of drying/drying after the draining step sl1 of the rinsing stroke. In the drying step S11, the control device 12 drives the blower fan 7, and the water vapor generated in the washing tank 2 is discharged from the outside of the casing 1 through the exhaust port to dry the laundry. However, the dishwashing machine 1001 of the embodiment does not need to perform the drying step S11. In the washing step S1 and the normal temperature washing steps S3, S5, S7 and the heating washing step 'S9, first, the control device 12 opens the water supply valve 3 to store the washing water at the bottom of the washing tank 2, and then 'drives the washing. The pump 4 supplies the washing water to the nozzles 41 to 44 via the water dividing device 50. The washings supplied to the nozzles 41 to 44 - 20 water are sprayed onto the washings contained in the dish holders 48, 49, and the washings can be washed and washed. The water dividing device 50 can selectively supply the stored washing water to the nozzles 41 to 44. The washing water is again stored in the bottom of the washing tank 2, and is again supplied to the nozzles 41 to 44 by the washing pump 4 and recycled. In the draining steps S2, S4, S6, and S8, the control device 12 drives the drain pump 6 and the drain water is drained by the drain port 8 through the drain passage 59 to the outside of the washing tank 2 (four) housing i through the drain passage 59. . In the table drying machine of the embodiment, the operator can switch between the normal operation mode 5 and the silent operation mode at any time by the operation panel 13 disposed on the face of the casing 1. In the silent operation mode, the control device (10) lowers the rotational speed of the washing pump 4, the drain pump 6, and the blower fan 7 than in the normal operation mode, and lowers the noise generated by the washing stroke and the flushing stroke in comparison with the normal mode. The operation of the draining step in the normal operation mode of the dishwashing machine 1001 will be described. Fig. 6 is a view showing the rotational speed of the drain pump 6 in the draining steps S2, S4, s6, 10 S8, S1 in the normal operation mode. When the control device 12 ends the washing step S1 or the rinsing steps S3, S5, S7, the washing is stopped, and the drain pump 6 is started to start the draining step. When the draining step is started, the control device 12 first causes the drain pump 6 to be magically driven for a predetermined time T1 at a rotational speed of 3 rpm. Then, the drain pump 6 is driven at a secondary rotation speed R2 of 15 1500 rpm lower than the primary rotation speed R1 to discharge the washing water. Then, the control device 12 stops the drain pump 6 at the time point τρι when the washing water stored at the bottom of the washing tank 2 decreases, and concentrates the washing water on the drain port 8. At the time point TP2 at which the washing water concentrates on the drain port 8, the control unit 12 raises the drain pump 6 to three rotation speeds R3 of 3,500 rpm in one breath, and then discharges the washing water concentrated in the drain port 20 8 in one breath. Thereafter, at the time point TP3, all the washing water stored in the washing tank 2 is discharged, and the control device 12 stops the drain pump 6, and ends the draining step. At this time, the drain pump 6 is driven at three rotation speeds R3 (3,500 rpm) higher than the primary rotation speed R1 to generate noise. Further, at this time, since the amount of the washing water is small, the air enters the drain pump 6 from the inlet 8A, and noise is generated. 16 200847986 In addition, in the dishwashing machine of the embodiment, the operation of the drain pump 6 in the normal operation mode is not limited to that shown in Fig. 6. Next, the operation of the draining step in the silent operation mode of the dishwashing machine will be described. Fig. 7 is a view showing the rotational speed of the drain pump 6 in the draining steps 5 S2, S4, S6, S8, and S1G in the silent operation mode. When the control device 12 ends the washing step (4) flushing step, S5, S7, ah, the washing fruit* is stopped, and the drain pump 6 is started, and the draining step is started. When the draining step is started, the control unit 12 first causes the drain pump 6 to be driven for a predetermined time T1〇1 at a rotational speed R101 of 3 〇〇〇. At the time when the amount of water remaining in the bottom of the washing tank 2 is reduced, the control device 12 drives the drain pump 6 at a rotational speed R102 of 150 rpm lower than the rotational speed R101, and discharges it in storage. Wash the water around the drain 8 of the tank 2. Then, at time point TP102, all the washing water stored in the washing tank 2 is discharged, and the control device u stops the drain pump 6, and ends the draining step. As described above, the control unit 12 operates to perform the operation of driving the cleaning pump 4 a plurality of times and supplying the washing water to the washing tank 2 to be ejected onto the laundry. Further, the control device 12 supplies the washing water to the washing tank 2 after the driving of the washing pump 4 is performed a plurality of times, and after the stroke is ejected on the washing material, the operation is performed to execute the driving pump for the plurality of times. The washing water 20 is discharged from the washing tank 2 to discharge the washing water from the washing tank 2. Further, the control device operates to drive the drain pump 6 in a silent mode by driving the drain pump 6 and discharging the washing water from the washing tank 2 at least once. Further, as described above, in the silent operation mode, the control device 12 sets the rotational speed of the drain pump 6 to the primary rotational speed R101 and drives the drain pump 6 17 200847986 to make the rotational speed of the drain pump 6 from _ times _ speed country The lowering speed R1G2 is lowered to a lower rotation speed than the one rotation speed, and the fruit 6 is driven. Then, the control device 12 operates to drive the drain pump 6 at a rotational speed not exceeding the second rotation speed of 2 until the washing tank 2 finishes discharging the washing water. 5 In the normal operation mode shown in Fig. 6, the control unit 12 drives the drain pump 6 at a three-time rotation speed R3 which is higher than the first-time rotation speed at the time point at which the water discharge step starts. In the silent operation mode shown in Fig. 7, the control device 12 drives the drain pump 6 at the second rotation speed & 1〇2 at the time interval TP101 until the time point τρι〇2 at the end of the draining step, The drain pump 6 is driven at a rotational speed higher than the rotational speed of 10 degrees 11102. Thereby, the dish washer 1〇〇1 can reduce the noise generated in the normal operation mode in the silent operation mode. When the drain pump 6 is driven in the silent operation mode shown in Fig. 7, the general operation mode shown in Fig. 6 lowers the discharge capacity of the washing water. By setting the discharge time TS of Fig. 7 to be longer than the enthalpy shown in Fig. 6, the washing water can be discharged from the clean tank 15 and the liquid can be finished. Fig. 8 is a view showing the rotational speed of the drain pump 6 in the other drainage steps in the silent operation mode of the dish washing machine 1〇〇1 of the embodiment. In Fig. 8, the same reference numerals are assigned to the same as the rotational speed or time point shown in Fig. 7, and the description thereof is omitted. In the normal operation mode shown in Fig. 6, the control unit 12 lowers the rotational speed of the drain pump 6 from the primary rotational speed R1 to the secondary rotational speed R2 within the inclination SL1 at the time point ΤΡ1. In the silent operation mode shown in Fig. 8, the control unit 12 causes the rotational speed of the drain pump 6 to be lower than the inclination SL2 of the tilt SL1 at the time point ΤΡ101, and is lowered from the primary rotational speed R101 to the secondary rotational speed R102. Thereby, the dish washer 1001 can reduce the noise generated in the normal operation mode in the 18 200847986 # sound operation mode. Fig. 9 is a view showing the rotation speed of the drain pump 6 in the other drainage steps in the silent operation of the dish washer 1〇〇1 of the embodiment. In the Fig. 9, the same rotation speed or time point as shown in Fig. 7 is assigned the same reference numeral and the description thereof is omitted. As shown in Fig. 9, in the silent operation mode, the control device 12 lowers the rotational speed of the drain pump 6 from the suspect rotation speed R101 to the secondary rotation speed R102 at the time point TP101, and then the drain pump 6 is stopped. Then, the control device 12 activates the drain pump 6 and is driven at the three rotation speed R103. The tertiary rotation speed R103 is not greater than the secondary rotation speed 10 R102. Thereby, the dish washer 1001 can reduce the noise generated in the normal operation mode in the silent operation mode. Further, in the silent operation mode shown in Fig. 9, the control device 12 can also reduce the rotational speed of the drain pump 6 to the second time from the first rotation speed to the second time in the inclination of less than the inclination SL1 within the time point τριοι. Rotation speed r1〇2. In the dishwashing machine 1001 of the embodiment, the control device 12 may also be at least one, but not all, of the drainage steps of the drainage steps 32, 84, 86, 88, 810, as shown in Figures 7 through 9. The drain pump 6 is driven as shown in one of them. For example, the control device 12 drives the drain pump 6 in the draining steps S2, s4, S6, % as shown in one of the seventh to ninth diagrams, and may also be in the draining step ^0. The drain pump 6 is driven as shown in Fig. 6. In which of the drainage steps 82, 84, 86'88, and 310, the drain pump is driven in the silent operation mode, which can be preset by the control program stored in the control device. The dishwashing machine in the embodiment _ in the washing line 19 shown in Fig. 5 200847986 In the private and rinsing stroke, the operator can switch the general operation at any time by the operation panel disposed in front of the casing 丄In the mode and the silent operation mode, the tableware washing machine 1001 does not directly perform the operation mode = the drainage steps 82, 84, one, and the -_type cut = to =, and the transfer mode is not directly performed. To the silent operation mode coffee 2 'tableware laundering job in the general operation mode to perform the drainage step ... 'from the general operation mode to the silent operation mode, the control set 12 will be self-flushing (four) S3_ call the voice money line drainage step S6, S8, S1G. When the drainage lion is executed in the normal operation mode, the control unit will perform the drainage step, S8, and S10 in the silent operation mode from the normal operation mode to the silent operation mode. During the execution of the draining step % in the normal operation mode, when the normal operation mode is switched to the silent operation mode, the control device (10) performs the draining (four) by the flushing operation. During the execution of the draining step S8 in the - 丨5:= mode, when the normal operation mode is switched to the 曰 operating mode, the control device 12 performs the flushing step _ in the silent mode in the self-draining step. In this way, when the general operation mode is switched to the silent operation mode during the cleaning process of the dishwasher, the control is performed from the flushing step below the draining step to perform the flushing step and the draining step in the silent mode. The 2 control clothes 12 is driven by the washing tank 2 to be washed and replaced by one person in the private order. If the general operation mode is switched to the silent operation mode, it will be repeated several times. The next trip in the trip, which is the under-travel, starts to drive the drain seal in silent operation mode. Thereby, it is possible to avoid the problem caused by switching to the silent operation mode to drive the drain water pump 6 during the normal operation mode driving. Since the dishwashing machine is in the draining step, the rotational speed of the drain pump 6 is not higher than the speed of the second money, so there is no sound of the washing water colliding with the air in the state of almost discharging 5. #钱净机1GG1巾' By the door that will be drained when the mute is red. In addition, the running mode of the car is long, and the washing water in the washing tank 2 can be discharged. Next, the operation of the washing pump 4 will be described. Fig. 1A and Fig. 1B respectively show the rotational speed of the washed fruit 4 in the normal operation mode and the silent operation mode. As shown in FIG. 10A, when the cleaning step s2 or the rinsing steps S4, S6, S8, and S9 are executed in the normal operation mode, the control device 12 causes the second speed increase rate QL1, such as 21 〇〇rpnv/sec. The rotation speed of the washing pump 4 is increased to 15 first rotation speed Q1, for example, 4,200 rpm. As shown in FIG. 10B, when the cleaning step S2 or the rinsing steps S4, S6, S8, and S9 are executed in the silent operation mode, the control device 12 is at a second speed increase rate QL2 that is slower than the first speed increase rate qL1. At 450 rpm/sec, the rotational speed of the washing pump 4 is gradually increased to the icing speed Q2, for example, 36 rpm. Thereby, the control device 12 can start the washing pump 4 more quietly than the normal operation mode in the 20 silent operation mode. As shown in FIG. 10A, in the normal operation mode, the control device 12 increases the rotational speed of the cleaning pump 4 to the first rotational speed Q and then the second rotational speed Q1 during the first rising time T201 (for example, between 2 seconds). Drive feed pump 4. Further, as shown in FIG. 10B, in the silent operation mode, the control device 12 raises the rotational speed of the washing pump 4 to the second square in the second upper 21 200847986 10 15 \ 20 liter time T202 (for example, 8 seconds). The speed Q2 is then driven to the fruit* by the brother 2$. In other words, in the dish washer of the embodiment, the rise time T2 〇 2 (for example, 8 seconds) at which the cleaning pump 4 reaches the second rotation speed Q2 in the silent operation mode shown in FIG. 10B is set to be 10A. In the general rise mode shown, the gate T201 (for example, 2 seconds) is long. Thereby, the control device 12 can start the washing pump 4 quietly in the silent operation mode than in the normal operation mode. ^ The second rotation speed Q2 in the silent operation mode is set to be lower than the first rotation speed Q1 in the vehicle six operation mode. Therefore, during the driving of the washing water 4, that is, in the washing step S1 or the washing steps S3, S5, and S7, the washing operation can be driven quietly in the silent operation mode than in the normal operation mode, and the embodiment is executed. In the tableware washing machine 1001, the control can be used to drive the fruit 6 and the clean seed 4 in the normal operation mode and the silent operation mode. In the dish washer 1001 of the embodiment, the control device 12 can drive the drain pump 6 and the washing fruit 4 < ' in one of the normal operation mode and the silent operation mode. Thereby, at least the cleaning step si and the rinsing step, the driving of the washing pump 4 of the 匕5, S7, and S9, and the driving of the draining steps S2, S4, S6, and 水果\ of the fruit 6 can be reduced. The noise generated by one.
