FIG. 1 is a cross-sectional view showing the configuration of the dishwasher according to the first embodiment of the present invention. In FIG. 1, a cleaning means 4 having a cleaning nozzle 2 for jetting and circulating cleaning water to the object to be cleaned and a cleaning pump 3 for pressurizing the cleaning water below a cleaning tank 1 for storing the object to be cleaned such as tableware. And the heating means 5 which heats washing water and heats up is arrange | positioned. Further, the drying means 9 has a blower 6 that blows outside air to discharge moisture in the cleaning tank 1 and dry the inside of the cleaning tank 1, and an exhaust port 7 that discharges moisture in the cleaning tank 1. Is provided with an inflow port 10 through which outside air flows in and an outflow port 11 through which air in the cleaning tank 1 (cleaning tank internal air) is discharged.

  An air volume distribution means 12 for distributing the air volume is connected to the downstream side of the blower 6, and an external air passage 14 for introducing outside air into the mixing unit 13 and an inlet 10 of the cleaning tank 1 are connected to the downstream side of the air volume distribution means 12. A cleaning tank internal air passage 15 communicating with the mixing unit 13 through the cleaning tank 1 and the outlet 11 is disposed.

  This air volume distribution means 12 distributes the air volume by changing the flow resistance to the outside air passage 14 and the cleaning tank inside air passage 15, and is a valve that changes the opening area to the outside air passage 14 and the cleaning tank inside air passage 15. The air volume is distributed by the body part 16, and the flow rate ratio at the time of mixing the outside air and the cleaning tank inside air in the mixing part 13 is changed.

  Further, the mixing unit 13 communicates the outlet side with the exhaust port 7, communicates the inlet side of the mixing unit 13 with the outflow port 11 that is the outside air passage 14 and the cleaning tank internal air passage 15, and the mixing unit 13 includes The mixing promoting means 17 for promoting the mixing of the outside air and the cleaning tank internal air is arranged downstream of the junction 18 where the outside air and the cleaning tank internal air merge.

  The control means 19 controls the drying means 9. The air volume control section 20 that controls the air volume of the blower 6, the opening degree control section 21 that controls the opening degree of the valve body section 16, and the downstream side of the mixing section 13. A temperature control unit 23 that sets a control amount to the air volume control unit 20 or the opening degree control unit 21 based on the temperature detected by the provided temperature detection unit 22 is provided.

  Further, the pulsation control unit 24 drives the air volume fluctuation unit 25 that changes the air volume of the blower 6 by increasing or decreasing with time, or the valve body 16 of the air volume distribution means 12 to drive the outside air passage 14 and the cleaning tank. A distribution fluctuation control unit 26 is provided for changing the distribution state by changing the opening area to the air passage 15 over time. During the drying operation, the pulsation control unit 24 gives a flow velocity fluctuation to the flow of the outside air or the air in the washing tank. The pulsation control unit 24 controls the valve body 16 of the blower 6 or the air volume distribution unit 12 and mixes in the mixing promotion unit 17. Acts to promote

  The cleaning tank 1 is provided with a water supply pipe 28 provided with a water supply valve 27 for supplying cleaning water and a drain pipe 30 provided with a drain valve 29 for draining the cleaning water, and a slide body 32 that can be drawn out from the housing 31. It is stored. The slide body 32 is provided with a vent 33 communicating with the outside.

  FIG. 2 shows the mixing promoting means 17 shown in FIG. 1. This mixing promoting means 17 sequentially forms a planar body 37 having a protruding end 36 extending from the wall surface 34 into the mixing passage 35 in the flow direction. The turbulence promoting bodies 38 are alternately arranged so that the directions of the projecting ends 36 are different, and the flow direction along the passage at the inlet of the mixing passage 35 (the white arrow in the figure) is blocked by the planar body 37 in the figure. As shown by the black arrows, the flow is bent and reversed by sequentially bypassing the protruding ends 36.

  FIG. 3 shows another configuration example of the mixing promoting means 17 shown in FIG. 1. The mixing promoting means 17 is provided with a porous body 40 having a large number of communication passages 39 communicating with fine gaps in the mixing portion 13. As the material of the porous body 40, various materials such as metal, ceramic, and resin can be used.

  About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. First, the slide body 32 is pulled out from the housing 31 to store the tableware that is the object to be cleaned in the cleaning tank 1, and the slide body 32 is returned to the original state to start cleaning. When the cleaning operation starts, the water supply valve 27 is opened to supply water to the cleaning tank 1 from the water supply pipe 28. When a predetermined amount of water is supplied, the water supply valve 27 is closed to stop the water supply, and the heating means 5 and the cleaning means 4 When the cleaning pump 3 is operated, hot water is ejected from the cleaning nozzle 2 and sprayed on the tableware that is the object to be cleaned.

  The cleaning nozzle 2 is rotated by the reaction force of the cleaning water jetting, so that the cleaning water is spread over the object to be cleaned, thereby improving the cleaning performance. Here, the case where the heating means 5 is operated and washed with warm water is shown. However, if the object to be cleaned is weakly soiled, the heating means 5 may be operated without operating the water supply temperature, and the object to be cleaned may be contaminated. If it is strong, wash with detergent. When the cleaning operation is completed, the drain valve 29 is opened to drain the cleaning water from the drain pipe 30 to the outside of the housing 31, and when draining is completed, the drain valve 29 is closed.

  In the next rinsing operation, water is supplied in the same manner as in the cleaning operation without adding detergent, and hot water is ejected from the cleaning nozzle 2 by the operation of the heating means 5 and the cleaning pump 3 and sprayed on the tableware to be cleaned. Let Since the object to be cleaned is dried after the rinsing operation, the object to be cleaned is preferably warmed in the rinsing operation, and sterilization can be performed by rinsing with high-temperature water of about 70 ° C to 80 ° C. . After the rinsing operation is completed, the rinsing water in the cleaning tank 1 is drained in the same manner as at the end of the cleaning operation.

  In the next drying operation, the blower 6 is operated and the outside air passage 14 is cleaned by the air volume distribution means 12 in order to discharge the air in the cleaning tank 1 that has become hot and humid by the rinsing operation and dry the object to be cleaned. The air is diverted to the tank internal air passage 15 and the outside air is sent to the mixing unit 13 and the cleaning tank 1. In particular, when the rinsing operation with high temperature water is performed, the opening degree control unit 21 of the control means 19 is used at the start of the operation of the blower 6 so that the high temperature and high humidity air in the cleaning tank 1 is not directly discharged from the exhaust port 7. The opening area is controlled so that the amount of air to the outside air passage 14 side is larger than the amount of air to the washing tank inside air passage 15 side. In this way, the air volume is controlled so that the outside air and the cleaning tank inside air flow from the merging portion 18 to the mixing portion 13, the flow is mixed by the mixing accelerating means 17, and a uniform mixture with reduced temperature and humidity spots is obtained. It exhausts from the exhaust port 7.

  Further, as the drying operation proceeds, the humidity of the cleaning tank air decreases due to the inflow of the outside air into the cleaning tank 1, and the enthalpy of the cleaning tank air decreases, so that the temperature of the exhaust gas flowing out from the exhaust port 7 is a predetermined value. The amount of outside air required for cooling below can be reduced. Accordingly, the amount of the outside air flow to the mixing unit 13 can be reduced as the drying state progresses, and the amount of the air flowing into the washing tank 1 is increased by diverting the amount to the washing tank air passage 15 side. The drying performance of an object can be improved. Therefore, based on the temperature detected by the temperature detector 22, the opening controller 21 drives the valve body 16 of the air volume distribution means 12 with a stepping motor (not shown) or the like by the signal of the temperature controller 23, and the opening is reduced. The drying rate is increased by changing the air flow rate to the cleaning tank air passage 15 side.

  As a result, during the drying operation, the air in the high-temperature, high-humidity cleaning tank (cleaning tank internal air) is used to cool the outside air for cooling, and the mixing section is free from uneven spots. Can be prevented.

  Further, by controlling the air volume of the cleaning tank air with the air volume distribution means 12, the outside air and the high-temperature and high-humidity cleaning tank air are mixed without spots in the mixing section during the drying operation, The amount of air in the cleaning tank is increased according to the temperature and humidity state, and both cooling of the exhaust and prevention of hot air feeling by reducing moisture and improvement of drying performance can be achieved.

  In addition, as shown in FIG. 2, the turbulence promoting body 38 in which the planar bodies 37 are alternately arranged so that the directions of the protruding ends 36 are sequentially different in the flow direction, and the flow direction along the passage at the inlet of the mixing passage 35 ( As shown by the black arrow in FIG. 2, the mixture is changed to a bending and reversing flow that bypasses the projecting end 36 as shown by the black arrow in FIG. Can be simplified and the cost can be reduced.

  Further, an overlap Lp is provided in which the positions of the projecting ends 36 arranged sequentially overlap each other, and the length of the overlap Lp is from 1/4 (Lp = Lw / 4) to 1/3 with respect to the total passage width Lw. A length of about (Lp = Lw / 3) or more is preferable. By ensuring the overlap, it is possible to prevent the occurrence of a straight flow path and enhance the effect of stirring and mixing. In this way, by providing the overlap Lp, it is possible to prevent the generation of a flow path that can travel substantially straight, and further promote the mixing of the cleaning tank inside air and the outside air.

  In addition, by flowing the porous body 40 having a large number of communication passages 39 through which fine gaps communicate as shown in FIG. The structure is simplified and made compact, and the size and cost can be reduced.

  Further, in the pulsation control unit 24, the air volume of the blower 6 is repeatedly increased and decreased over time by the air volume variation unit 25, and the flow rate is varied in the flow of the outside air or the cleaning tank internal air to cause pulsation. Mixing is promoted by increasing the flow turbulence.

  Further, the distribution fluctuation control unit 26 changes the distribution state by changing the air volume distribution to the outside air passage 14 and the washing tank inside air passage 15 with the passage of time, and gives the flow velocity fluctuation to the flow of the outside air and the washing tank inside air. Or, by causing the flow pattern in the merging portion 18 to fluctuate due to fluctuations in the flow rate ratio, it acts to further promote mixing, and drying is promoted when the distribution flow rate to the washing tank 1 is increased. Drying performance can be improved.

  In this way, the disturbance of the flow in the mixing section 13 can be promoted, the length of the passage required for mixing can be shortened, the size can be reduced, and the drying performance can be improved by changing the distribution flow rate.

  FIG. 4 shows that the air volume of the blower 6 is repeatedly increased and decreased over time by the control of the air volume changing unit 25. From the state where the air volume fluctuation range ΔQa is given to a certain air volume setting value Qa, As the drying progresses, the set value is increased to the air volume set value Qb (Qa <Qb) in order to increase the drying speed, and the fluctuation range is further changed to the air volume fluctuation range ΔQb (ΔQa> ΔQb).

  The reason why the air flow fluctuation width is reduced along with the increase in air flow is that the air speed increases and the flow turbulence increases due to the air flow increase, so that the mixing can be increased even if the air flow fluctuation width is reduced. The noise accompanying the air volume fluctuation of 6 can be reduced. In this way, the flow turbulence can be promoted by pulsating by changing the flow velocity.

  Needless to say, the mixing can be further promoted by increasing the air flow fluctuation range as the air flow increases.

  FIG. 5 shows the air volume distribution ratio to the cleaning tank internal air passage 15 when the air distribution to the outside air passage 14 and the cleaning tank internal air passage 15 is changed over time by the control of the distribution fluctuation control unit 26. Thus, when all the air volume of the blower 6 is flowed into the cleaning tank air passage 15, it is displayed as the air volume distribution ratio 1.

  In FIG. 5, the setting value is increased to the air flow distribution ratio setting value Rb in order to increase the drying speed as the drying progresses from the state where the air flow distribution ratio fluctuation range ΔRa is given to a certain air flow distribution ratio setting value Ra. Ra <Rb) to increase the air volume to the cleaning tank air passage 15, and further change the fluctuation range to the air volume distribution ratio fluctuation range ΔRb (ΔRa> ΔRb). By changing the distribution ratio without changing the air volume of the blower 6, pulsation is generated in the flow to promote mixing, stabilizing the air volume of the blower 6, suppressing fluctuations in operating noise, and improving quietness. it can.

  Here, the increase in the air volume distribution ratio to the cleaning tank internal air passage 15 and the decrease in the air volume distribution ratio fluctuation range are caused by fluctuations in the air flow resistance when the air volume ratio to one of the passages is large. This is because the fluctuation of the operation noise of the blower 6 is reduced by suppressing the air volume fluctuation. As described above, the flow rate ratio between the outside air and the cleaning tank inside air is fluctuated, the flow velocity is fluctuated and the flow distribution is fluctuated to further promote the flow disturbance.

  4 or 5 shows the case where the setting value of the air volume or the air volume distribution ratio is changed stepwise, but it may be changed smoothly like a ramp, and the setting value is not changed. Needless to say, only the fluctuation range may be added.

  Further, the pulsation control unit 24 includes an air volume variation control unit 25 that varies the air volume of the blower 6 and a distribution variation control unit 26 that varies the distribution state of the air volume distribution unit 12. The flow fluctuations can be expanded by overlapping both actions, and the fluctuations in the flow velocity and the flow distribution can be further increased to increase the flow disturbance and promote the mixing.

  As described above, in the present embodiment, the drying means includes the mixing unit that mixes the outside air arranged in the upstream side of the exhaust port and the cleaning tank inside air, and the outside air in the mixing unit and the cleaning tank inside air. By providing mixing promotion means to promote mixing, during drying operation, outside air is mixed in the mixing section for cooling with high-temperature and high-humidity cleaning tank air (cleaning tank air), and cooling of the exhaust. And the hot air feeling of the exhaust can be prevented by reducing moisture.

  Further, the drying means according to the present embodiment is provided with an air volume distribution means for changing the flow rate ratio between the outside air and the washing tank inside air in the mixing promoting means, so that the high temperature and high humidity cleaning is performed during the drying operation. A sufficient amount of outside air is mixed with the air in the tank (cleaning tank air) in the mixing section for cooling, and both cooling of the exhaust and prevention of hot air feeling by reducing moisture and improvement of drying performance are compatible. it can.

  Further, the mixing promoting means of the present embodiment is arranged by alternately arranging planar bodies having projecting ends extended from the wall surface to the mixing passage so that the directions of the projecting ends are sequentially different in the flow direction. By providing the turbulence promoting body that bends and reverses the flow direction, the configuration can be simplified and the cost can be reduced.

  Further, the turbulence promoting body according to the present embodiment is provided with an overlap portion where the positions of the projecting ends that are sequentially arranged overlap each other, thereby preventing the generation of a flow path that can move substantially straight, and The mixing of air and outside air can be further promoted.

  In addition, the mixing promoting means of the present embodiment includes a porous body having a large number of communication passages through which fine gaps communicate, thereby simplifying the configuration and reducing the size, and reducing the size and cost. Can be

  Further, the mixing promotion means of the present embodiment is provided with a pulsation control unit that gives a flow velocity fluctuation to the flow of the outside air or the air in the cleaning tank, thereby promoting the disturbance of the flow and the passage required for mixing. The length can be shortened and the size can be reduced.

  The mixing promotion means 17 includes a rotating body 43 that rotatably supports a blade 41 that stirs a flowing fluid (indicated by a white arrow in the figure) with a support shaft 42. The rotating body 43 forcibly mixes the fluid flowing by a driving unit 44 formed by an electric motor or the like, and the driving unit 44 is fixed to the mixing passage 35 via a holding body 46 having an opening 45.

Simultaneously with the start of the drying operation, the drive unit 44 is operated to rotate the rotator 43 in the mixing passage 35, and the mixed flow of the cleaning tank inside air and the outside air is stirred by the blades 41 to equalize the temperature and humidity. In this way, since stirring is performed by the rotating body 43, mixing can be performed with a short passage length, and the size can be reduced.
