[0018]
Next, as shown in FIGS. 2 to 5, the cleaning tank 4 is formed in a box shape having an open top surface and having the bottom plate 4 </ b> A with as few asperities as possible, and is thin. That is, the cleaning tank 4 has the same area as that of the cleaning chamber 2 and the depth is substantially the same in the entire area, and the cleaning water is stored in the entire area.
[0019]
Thereby, even if the water level is lowered, the surface area of the cleaning water is increased, so that conventionally, only about 14 liters of cleaning water can be stored in a part of the deep portion. In the cleaning tank 4, about 20 liters of cleaning water can be stored.
[0020]
In addition, a rear end flange 4B that protrudes forward and is partially cut out is formed at the opening edge of the rear end of the cleaning tank 4. A front end flange 4C is formed at the front end of the cleaning tank 4 so as to face the rear end flange 4B and project forward. The cleaning tank filter 17 formed in a stitch shape of about 2 to 3 mm is placed on the front end flange 4C and the rear end flange 4B.
[0021]
Further, a cleaning pump 18 shown in FIGS. 7 and 8 is located in the cleaning tank 4, and this cleaning pump 18 supplies cleaning water to the upper and lower cleaning nozzles 14A and 14B. A pump motor 19 for rotating the cleaning pump 18 is provided on the machine chamber 3 side with the bottom plate 4A of the cleaning tank 4 interposed therebetween.
[0022]
The cleaning pump 18 has a suction port 20A for sucking cleaning water on the lower surface, and has a discharge port 20B for discharging cleaning water on the side surface above the suction port 20A and made of a cylindrical resin. The casing 20 is attached to the rotary shaft 19A of the pump motor 19 and is located above the suction port 20A, and is rotatable in the casing 20, and is attached to the lower surface of the casing 20, and the suction port. The upper plate 22 in which holes are formed at the same position as 20A, and the upper plate 22 include a lower plate 24 provided with a plurality of cylindrical spacers 23 at a predetermined interval (for example, about 15 mm).
[0023]
In addition, by setting the width between the spacers 23 so that an object to be cleaned such as a spoon or a fork cannot pass through, even if the object to be cleaned falls into the cleaning tank 4 by mistake, it is caught by the cylindrical spacer 23. Further, it is possible to prevent the washing pump 18 from being damaged as much as possible.
[0024]
Furthermore, since the impeller 21 is located above the suction port 20A of the casing 20, even if a part of the object to be cleaned, such as a handle of a spoon or fork, reaches the suction port 20A, Since it is sandwiched between the upper plate 22 and the lower plate 24 and does not reach the impeller 21, it is possible to prevent the impeller 21 from being damaged by the object to be cleaned. Therefore, it is not necessary to prepare a separate cleaning pump filter and the cost can be reduced.
[0025]
Further, since the suction port 20A of the cleaning pump 18 is at the bottom and the cleaning water is sucked from the entire circumferential surface of the cleaning pump 18, the thickness of the cleaning tank 4 is reduced, and even if the water level is low, the vortex Can be prevented as much as possible, and even if a vortex is generated, air suction can be prevented as much as possible.
[0026]
Further, a motor attaching / detaching hole 25 through which the pump motor 19 can be inserted is formed in the cleaning pump 18 mounting portion of the cleaning tank bottom plate 4A, and the pump motor 19 has a rotating shaft 19A facing upward. Attached to the lower plate 24. Therefore, the pump motor 19 is positioned below the cleaning tank 4.
[0027]
That is, the cleaning pump 18 and the pump motor 19 are opposed to each other with the lower plate 24 interposed therebetween, and are formed in a unit shape. The lower plate 24 is formed of a member such as soft rubber around the motor mounting hole 25 of the bottom plate 4A. It is attached via a sealing packing 26 formed by
[0028]
In this way, the pump motor 19 is placed vertically, and the motor attaching / detaching hole 25 larger than the diameter of the pump motor 19 is formed. Therefore, when the pump motor 19 is removed, it is only necessary to pull it up as it is.
[0029]
The cleaning tank 4 is provided with a drainage drain 27 in order to keep the cleaning water level constant. The drainage drain 27 is attached to a drainage portion 28 having a drainage port formed in the bottom plate 4A. Since the drainage port of the drainage portion 28 is formed in the bottom plate 4A, the drainage port 28 is positioned below the suction port 20A of the cleaning pump 18. In addition, a cleaning water heater 29 for keeping the cleaning water at a predetermined temperature, for example, a temperature of about 60 ° C. is provided in the cleaning tank 4.
[0030]
In this way, by attaching the pump motor 19 directly below the cleaning pump 18 and forming the motor attaching / detaching hole 25 in the bottom plate 4A of the cleaning tank 4, the cleaning pump 18 and the pump motor 19 remove the cleaning tank filter 17. Since the cleaning can be performed from the inside of the cleaning tank 4, the detachability workability related to the cleaning pump 18 is improved.
[0031]
Further, since the drain outlet of the drainage section 28 is located below the suction port 20A of the cleaning pump 18, when the drainage drain 27 is removed and the cleaning water in the cleaning tank 4 is drained, the inside of the casing 20 of the cleaning pump 18 It is possible to prevent washing water from remaining on the surface as much as possible.
[0032]
Next, as shown in FIGS. 3, 4, and 6, the rinsing tank 5 is located below the cleaning tank 4 with a small interval, and the rinsing tank 5 has the cleaning tank on the left side. The electrical box 6 is provided on the front side of the pump motor 19 of the pump 18.
[0033]
In addition, the water supplied from the external water system via the water supply pipe 30 and the water supply electromagnetic valve 31 is also used as the rinsing water in the rinsing tank 5, so that the rinsing water heater 32 is heated to a temperature of about 80 ° C. Is provided. Further, a rinsing pump 33 for supplying rinsing water heated in the rinsing tank 5 to the upper and lower rinsing nozzles 15A and 15B is attached to the front side of the rinsing tank 5 and next to the electrical box 6. ing.
[0034]
In this way, the washing tank 4 is made thin, and the rinsing tank 5 that is higher in temperature than the washing tank 4 is disposed below the washing tank 4 so that the washing tank 4 receives heat from the rinsing tank 5 and receives the heat. 4 can be heated.
[0035]
Accordingly, the heating amount of the washing water heater 29 is reduced, and an energy saving effect is obtained. Further, since the washing tank 4 and the rinsing tank 5 are not in contact with each other, the heat of the rinsing tank leaks to the washing tank through the tank wall surface. This can prevent the rinse water temperature in the rinse tank from being lowered by the wash water temperature in the wash tank.
[0036]
The reduction in the heating amount of the cleaning water heater 29 is specifically to lower the energization rate of the cleaning water heater 29 or to reduce the heat capacity of the cleaning water heater 29 from the design stage.
[0037]
Furthermore, by making the washing tank 4 thin and forming a space in which the rinsing tank 5 can be stored under the washing tank 4, the level of drainage of the washing tank 4 can be increased, and a space of 175 mm from the installation floor surface. Can be secured. For this reason, drainage can be smoothly introduced from the drainage pipe provided in the drainage section 28 to the drainage pit formed on the installation floor surface, thereby improving drainage.
[0038]
Next, water supply and drainage water piping of the dishwasher 1 will be described with reference to FIGS.
First, as described above, the rinsing tank 5 is provided with a water supply pipe 30 for introducing tap water. The water supply pipe 30 is located on the front side of the rinsing tank 5. Further, the rinsing pump 33 is located on the front side of the rinsing tank 5 like the water supply pipe 30, and a rinsing pump discharge pipe 34 is connected to the rinsing pump 33.
[0039]
As described above, since the water supply pipe 30 is arranged on the front side of the dishwasher 1, the workability when the dishwasher 1 is installed is improved, and the water supply pipe 30 is twisted to connect the water supply pipe 30 itself or the water supply pipe 30 to the external water supply. It is possible to prevent a load from being applied to the nut when connecting to the system.
[0040]
The rinse discharge pipe 34 is located in the cleaning tank 4 and is connected to an upper rinse water supply pipe 35A for supplying rinse water to the upper rinse nozzle 15A. And in order to supply rinse water to the lower rinse nozzle 15B, the lower rinse water supply pipe 35B has branched from the said upper rinse water supply pipe 35A.
[0041]
Accordingly, the water introduced from the water supply system is heated in the rinse tank 5 and supplied as the rinse water to the upper rinse nozzle 15A via the rinse water discharge pipe 34 and the upper rinse water supply pipe 35A. It will be supplied to the rinsing nozzle 15B through the rinsing water supply pipe 35B branched from 35A.
[0042]
On the other hand, a cleaning water supply pipe 36 for supplying cleaning water to the upper and lower cleaning nozzles 14A and 14B is provided in the cleaning tank 4 and connected to the discharge port 20B of the cleaning pump 18. The supply pipe 36 has a cylindrical shape formed of 1 mm thick stainless steel (SUS304).
[0043]
Thus, by providing the cleaning pump 18 in the vicinity of the cleaning water supply pipe 36 in the cleaning tank 4, the cleaning pump 18 and the cleaning water supply pipe 36 can be connected in the shortest distance. The cleaning water supply capacity to the upper and lower cleaning nozzles 14A and 14B can be greatly improved.
[0044]
Further, since the cleaning pump 18 itself is located in the cleaning water in the cleaning tank 4, the piping that connects the cleaning pump 18 and the cleaning water supply pipe 36 and the waterproof seal between the cleaning tank and the piping, which are conventionally required, are unnecessary. As a result, the cost will be greatly reduced.
[0045]
The cleaning water supply pipe 36 extends laterally along the bottom surface 4A in the cleaning tank 4 to the substantially central portion of the back surface of the cleaning chamber 2, and is attached to a back plate 37 that forms the back surface of the cleaning chamber 2. Along the top. The upper rinse water supply pipe 35A and the lower rinse water supply pipe 35B are located beside the wash water supply pipe 36.
[0046]
Further, the washing water supply pipe 36, the upper rinse water supply pipe 35A and the lower rinse water supply pipe 35B are located in a notch formed in the rear end flange 4B of the washing tank 4, and the notch The cleaning chamber 2 and the cleaning tank 4 are partitioned by covering with a partition plate 38 in a state where the tubes 36, 35 </ b> A, 35 </ b> B are inserted.
[0047]
The partition plate 38 of the present embodiment is inserted into each of the tubes 36, 35A, 35B, but the notch of the rear end flange 4B has a U-shape that fits into each of the tubes 36, 35A, 35B. The partition plate 38 may also be provided with a U-shaped notch that fits into each of the tubes 36, 35A, and 35B. In this case, the partition plate 38 can be easily attached and detached.
[0048]
Thus, since the cleaning chamber 2 and the cleaning tank 4 can be partitioned by the cleaning tank filter 17, the rear end flange 4B of the cleaning tank 4 and the partition plate 38, the object to be cleaned is being cleaned in the cleaning chamber 2. Residues falling on the cleaning tank filter 17 are surely received by the cleaning tank filter 17.
[0049]
Further, the cleaning water supply pipe 36 also has a function as a rack stopper when the rack 12 is carried in, and it is not necessary to form a rack stopper on the rack rail 13 or the like, and the rear end of the rack rail 13 is more than necessary. Since it is not necessary to extend, cost reduction can be achieved.
[0050]
Next, the upper panel 7 is made of stainless steel and is inclined so that the lower part protrudes forward as shown in FIGS. Then, a predetermined amount A protrudes from the door front surface 40 when the cleaning chamber door 9 is closed as shown in FIG. In this manner, by tilting the upper panel 7, the control panel 8 provided on the upper panel 7 faces obliquely upward, and the operability for the user can be improved. Furthermore, by projecting the lower portion of the upper panel 7 forward by a predetermined amount A, it is possible to prevent the steam generated from the cleaning chamber 2 from hitting the control panel 8 as much as possible when the cleaning chamber door 9 is opened.
[0051]
11 and 12 show another embodiment, and a reverse inclined portion 39 that is inclined toward the cleaning chamber 2 is formed in the lower portion of the upper panel 7. As shown in FIG. 12, the lower end of the reverse inclined portion 39 is located closer to the cleaning chamber 2 than the front surface 40 of the cleaning chamber door 9 when the cleaning chamber door 9 is closed.
[0052]
By configuring as described above, when the cleaning chamber door 9 is opened, it is possible to prevent the steam generated from the cleaning chamber 2 from hitting the control panel 8 as much as possible, and when the cleaning chamber door 9 is opened, dew condensation occurs on the upper panel 7. However, since dew drops along the reverse inclined part 39 to the door back surface 41 of the washing room door 9 and is guided to the washing room 2, it is possible to prevent condensation water from dripping to the front side of the dishwasher 1 as much as possible. .
[0053]
Furthermore, by inclining the upper surface 42 of the cleaning chamber door 9 toward the cleaning chamber 2, even when the cleaning chamber door 9 is closed, dew passes along the reverse inclined portion 39 and the door of the cleaning chamber door 9. Since it drops on the upper surface 42 and is guided to the washing chamber 2 side, it is possible to prevent condensation water from dropping on the front side of the dishwasher 1 as much as possible.
[0054]
With the above configuration, the operation of the dishwasher 1 of the present invention will be described.
First, water supply to the rinsing tank 5 is started. This is because when the water supply electromagnetic valve 31 is opened, a predetermined amount of water is supplied into the rinse tank 5 from the external water system via the water supply pipe 30, and the supplied water is supplied to the rinse water heater 32 of the rinse tank 5. To about 80 ° C.
[0055]
The rinse water heated to about 80 ° C. is supplied by the rinse pump 33 to the upper and lower rinse nozzles 15A and 15B via the rinse pump discharge pipe 34 and the upper and lower rinse water supply pipes 35A and 35B. The rinsing water is sprayed from the upper and lower rinsing nozzles 15 </ b> A and 15 </ b> B into the cleaning chamber 2, and then passes through the cleaning tank filter 17 to be supplied into the cleaning tank 4.
[0056]
Here, since the capacity of the rinsing tank 5 is smaller than the capacity of the cleaning tank 4, the above-described operation is repeated a plurality of times until the water level sensor 43 provided in the cleaning tank 4 detects the full water level. To do. Furthermore, since it takes time until the washing tank 4 detects the full water level, the washing water heater 29 keeps the temperature at about 60 ° C. during that time. When the cleaning tank 4 reaches a full water level, a detergent is supplied into the cleaning tank 4 by a detergent supply device (not shown) to obtain cleaning water.
[0057]
Since the object to be cleaned can be cleaned in this state, the cleaning chamber door 9 is opened and the rack 12 on which the object to be cleaned is placed is stored as shown in FIG. Here, by pushing the rack 12 to the back side of the cleaning chamber 2, the rear end of the rack 12 comes into contact with the cleaning water supply pipe 36, and the rack 12 becomes an appropriate position where cleaning is possible.
[0058]
Next, when the cleaning switch (not shown) of the control panel 8 is pressed, the pump motor 19 rotates the cleaning pump 18. As a result, the cleaning water in the cleaning tank 4 is sucked in from the suction port 20A of the cleaning pump 18, is sent to the cleaning water supply pipe 36 from the discharge port 20B, and is supplied to the upper and lower cleaning nozzles 14A and 14B.
[0059]
Then, the cleaning water is jetted while the upper and lower cleaning nozzles 14 </ b> A and 14 </ b> B rotate, and the object to be cleaned placed on the rack 12 is cleaned. Thereafter, the sprayed cleaning water passes through the cleaning tank filter 17 of the cleaning tank 4 and returns to the cleaning tank 4. For this reason, a large residue dropped from the object to be cleaned is caught by the cleaning tank filter 17 and does not return to the cleaning tank 4.
[0060]
After such a cleaning operation is continued for a predetermined time, the operation proceeds to a rinsing operation.
In the rinsing operation, the pump motor 19 is stopped, and about 80 ° C. rinsing water already stored is driven to drive the rinsing pump 33 and supplied to the upper and lower rinsing nozzles 15A and 15B.
[0061]
By driving the rinse pump 33, the rinse water in the rinse tank 5 is sent to the upper and lower rinse nozzles 15A and 15B via the rinse pump discharge pipe 34 and the upper and lower rinse water supply pipes 35A and 35B.
[0062]
The rinse water sprayed from the upper and lower rinse nozzles 15 </ b> A and 15 </ b> B is washed away from the cleaning water adhering to the object to be cleaned, and is guided into the cleaning tank 4 through the cleaning tank filter 17.
[0063]
Here, when the rinsing water enters the cleaning tank 4, the cleaning water in the cleaning tank 4 is led from the upper part of the drainage drain 27 to the drainage part 28, and from the drainage pipe connected to the drainage part 28, Drain to the drainage pit formed on the installation floor.
[0064]
Normally, many of the small residues passing through the washing tank filter 17 have a lighter specific gravity than water. Therefore, when the rinse water enters the washing tank 4, the residues floating on the surface of the washing water are also drained from the drainage drain 27. It will be discharged into the pit.
[0065]
When the above cleaning and rinsing operations are completed, the cleaning chamber door 9 is opened and the rack 12 on which the object to be cleaned is placed is pulled out. At this time, since a large amount of steam is generated in the cleaning chamber 2 due to the high-temperature rinse water, the steam blows out from the cleaning chamber 2 simultaneously with the opening of the cleaning chamber door 9.
[0066]
Here, by forming the upper panel 7 as shown in any of FIGS. 9, 10, 11, and 12, it is possible to prevent the control panel 8 from being directly exposed to steam as much as possible.
[0067]
【The invention's effect】
As described above in detail, according to the first aspect of the present invention, since the cleaning water supply pipe is disposed in the cleaning chamber, the cleaning water supply pipe can be easily cleaned. Furthermore, the cleaning chamber and the cleaning tank can be partitioned by the cleaning tank filter, the cleaning tank flange, and the partition plate through which the cleaning water supply pipe is inserted. It can be reliably received with the washing tank filter.
[0068]
Therefore, the cleaning water supply pipe can be managed in a sanitary manner, and maintenance workability and replacement workability can be improved, and furthermore, the cleaning tank and the cleaning chamber can be reliably partitioned.
[0069]
According to the second aspect of the present invention, since the cleaning water supply pipe is located substantially at the center of the back surface of the cleaning chamber, this cleaning water supply pipe can be used in place of the rack stopper.
[0070]
Therefore, it is not necessary to separately provide a rack stopper or the like on the rear surface of the rack rail or the cleaning chamber, and the cost can be reduced.
