In the case of the washing tank 5 which is vertically long and narrow in width, the nozzle arms 15 and 17 cannot be so long because they are restricted by the width. For this reason, the front tableware cannot be sufficiently washed unless the front nozzle arm 15 is sufficiently arranged in front. Further, in consideration of the ease with which the residue filter 11 can be attached and detached, the water storage tank 9 must be disposed at the front of the cleaning tank 5. In the above configuration, since the nozzle base 13 is extended above the residue filter 11, that is, the water storage tank 9 after securing the space B for removing the residue filter 11, the front nozzle shaft 14, that is, the front nozzle arm 15 can be sufficiently arranged on the front side, and the dishes on the front side can be sufficiently washed. In addition, the residue filter 11 can be easily attached and detached via the removal space B.

It is preferable that the front side surface of the lower tank 7b is inclined from the tableware inlet to the bottom surface of the lower tank 7b. Thereby, the residue filter 11 can be slid and mounted above the water storage tank 9 along the front side surface of the lower tank 7b, so that the residue filter 11 is more easily mounted. FIG. 9 is a front vertical sectional view showing the internal configuration of the dishwasher 1. Referring to FIGS. 7 to 9, a water supply nozzle 19 is provided on the raised portion 12 on the left side of the rear end of the nozzle base 13. This water supply nozzle 19 is
A water supply port 20 formed integrally with the washing tank 5 and a water supply cover 21 covering the water supply port 20 are provided. The water supply nozzle 19 is connected to a water supply hose 22, and water sent from the water supply hose 22 is supplied from the water supply nozzle 19 into the cleaning tank 5. Thereby, the cleaning tank 5
Water is stored inside.

Referring again to FIG. 7, at the bottom of the washing tank 5, the right side (the position on the right of the nozzle base 13) has a heater extending long in the front-rear direction from the rear to the center and slightly to the front. (Seed heater) 23 is provided. The heater 23 is used for cleaning the cleaning tank 5 during cleaning.
Warm the water stored at the bottom of the. Further, at the time of drying, the air sent into the cleaning tank 5 by the blower (described later) and the inside of the cleaning tank 5 is heated. This heater 23
Has a double loop shape composed of an outer loop 23a and an inner loop 23b in order to increase the heating area.
3c is bent to the right, and the terminal portion 23d is made to come out of the tank 5 from behind the side wall of the cleaning tank 5. The heater 23 generates heat by being energized through the terminal portion 23d. In the cleaning tank 5 having a small width, the depth is longer than the width, and many accessories can be arranged along the long side wall. In other words, the side wall has more space on the side wall side than the rear wall side, and the terminal portion 23d is protruded on the side wall side where there is room, so that the terminal portion 23d is less likely to hinder other constituent members. Further, the terminal portion 23d is put out of the tank 5 from the side surface side, so that the terminal portion 23d
Can be prevented from coming out of the tank 5 from the rear wall and becoming difficult to be connected, and the terminal portion 23d can be prevented from obstructing other components arranged behind the heater 23.

An intake chamber 24 is provided behind the heater 23 and near the lower portion of the rear wall of the washing tank 5. An intake port 24a into the cleaning tank 5 is provided at a lower portion of the front surface of the intake chamber 24 (see FIG. 9). FIG.
FIG. 3 is a cross-sectional view of a main part showing a configuration of a heater cover 26, an intake chamber 24, and a blower 25. Referring to FIGS. 8 to 10, a blower 25 having a blower fan is provided at a position on the right rear side of the outer bottom surface of cleaning tank 5 (next to cleaning pump 10). The outside air is taken in by the operation of the blower 25 and is sent to the suction chamber 24, and is sent out as dry air from the suction port 24 a into the cleaning tank 5. The inner top surface 24b and the outer top surface 24c of the intake chamber 24 are spherical, and more specifically, are curved in a substantially semicircular shape in the air flow direction (see FIG. 10). Thus, the wind blown into the intake chamber 24 from below toward above is smoothly sent to the intake port 24a. Further, since the outer top surface 24c is also formed in a spherical shape, water hardly remains on the outer top surface 24c after cleaning. As described above, the terminal 23 d of the heater 23 extends out of the side wall of the cleaning tank 5 to the outside of the tank 5.
It does not get in the way of 3d. That is, the intake chamber 24 can be arranged in the space behind the heater 23.

Referring to FIGS. 7 and 10, the upper and front sides of the heater 23 are covered with a heater cover 26. The material of the heater cover 26 is a corrosion-resistant metal,
For example, stainless steel. The rear end of the heater cover 26 is connected to the intake port 24a. On the upper surface 26a of the heater cover 26, a large number of louvers (wind direction adjusting holes) 27 projecting downward are provided in two rows. A small round hole 28 is formed in the front surface 26b of the heater cover 26.
There are many open. Conventionally, the upper surface 26 of the heater cover 26
a, a large number of small round holes similar to the front surface 26b are formed.
6 and may come into contact with the heater 23. Here, by forming the louver 27, it is possible to prevent the tip of the chopsticks from entering.

At the time of drying, the blower 25 and the heater 23
Works. By the operation of the air blower 25, the air blown into the cleaning tank 5 is warmed through the heater 23 and rises, hits the tableware above, deprives the tableware of moisture, and is then provided with an exhaust port provided in the door 2. (Discussed below) to the outside of the machine. The direction of opening of the louver 27 is
The direction is opposite to the flow direction of the wind from 4a. That is, the opening of the louver 27 does not face the flow direction of the wind. When the opening direction of the louver 27 is oriented in the direction of the flow of the wind, the wind flows along the louver 27, the momentum of the wind increases, and the warm wind does not hit the dishes in the washing tank 5 and the front exhaust is exhausted. It is exhausted from the mouth (described later). In this regard, since the opening of the louver 27 does not face the direction of the flow of the wind, the above-described phenomenon can be prevented.

Referring to FIGS. 7 and 8, in front of the washing tank 5, outside the right wall surface, a water level detecting chamber 29 is provided.
Is provided. This water level detection chamber 29 is connected to the water storage tank 9 via a connection hose 72. A float (not shown) is disposed in the water level detection chamber 29, and the water level in the cleaning tank 5 is detected by detecting an increase in the water level of the float accompanying the rise in the water level in the cleaning tank 5. . In the case of the cleaning tank 5 having a small width, the depth is longer than the width, and many accessories can be arranged along the long side wall. In other words, the side wall has more space on the side wall side than the rear wall side, and the water level detection chamber 29 is provided on the side wall side with room, so that the water level detection chamber 29 is less likely to interfere with other components. Further, since the water level detection chamber 29 is provided outside the wall surface far from the water storage tank 9, bubbles generated in the cleaning tank 5 are removed from the water level detection chamber 29.
It is difficult to penetrate the water, and it is possible to prevent a decrease in water level detection accuracy due to the influence of bubbles.

FIG. 11 is a schematic side view showing the structure of the bottom of the washing tank 5. The water level detection chamber 29 is connected to the connection hose 7.
2 is connected to the water storage tank 9. Connection hose 72
Extends laterally substantially horizontally from the side surface of the water storage tank 9 along the outer bottom surface of the lower tank 7b, rises steeply upward along the side surface of the lower tank 7b, and is connected to the bottom surface of the water level detection chamber 29. I have. Thereby, since the length of the connection hose 72 can be lengthened, the bubbles generated in the cleaning tank 5 are less likely to enter the water level detection chamber 29, and the lowering of the water level detection accuracy due to the influence of the bubbles can be further prevented.

FIG. 12 is a plan view of the tableware basket 30.
FIG. 13 is a side view of the tableware basket 30. The tableware stored in the washing tank 5 is held by a tableware basket 30. The tableware basket 30 is formed of a plurality of wires in a basket shape. The tableware basket 30 mainly includes a lower basket 31 for holding plates and bowls, and an upper basket 32 (having a shelf shape) which is provided above a rear portion of the lower basket 31 and mainly holds only cups, hot water and the like. Have. The tableware basket 30 has a slim shape in accordance with the outer shape of the washing tank 5.
That is, the width dimension is considerably smaller than the depth dimension.

In the case of a slim dishwasher whose width is considerably narrow relative to the depth as in the dishwasher 1 of this embodiment, it is preferable that the upper basket 32 is provided above the rear part of the lower basket 31. More specifically, the lower basket 31 is
It is preferable that the upper cage 32 extends in the longitudinal direction from the front end to the rear end in the tank 5, and the upper cage 32 extends from the rear end of the lower cage 31 to approximately half forward. That is, most of the tableware basket 30 is pulled out from the tableware insertion port 6 to the back surface of the door 2 with a part of the rear part left in the cabinet 3. Since the amount of drawers is increased to make it easier to insert the dishes, the dishwasher 1 body is likely to fall forward due to the weight of the dishes.
Here, by disposing the upper basket 32 at the rear part, the center of gravity of the tableware basket 30 in which the tableware is stored can be made later, and the dishwasher when the tableware basket 30 is pulled out with the tableware stored therein. One body can be prevented from overturning.
Further, even if the upper basket 32 remains in the installed state, tableware can be easily put in the lower basket 31.

The lower basket 31 is provided with various holders corresponding to the types of tableware. Large plate holder 3 in front center
3 are provided. The platter holding portion 33 is formed by arranging a plurality of pairs of pins 34 whose upper portions are spread out in an inverted C-shape in the front-rear direction. I do. A bowl holding section 35 is provided on the rear right side of the platter holding section 33. Bowl holder 3
Reference numeral 5 denotes a plurality of gates 36 each having a central portion formed in a bowl shape and arranged in the front-rear direction. The bowl holding portion 35 normally holds a bowl, but is configured to hold a bowl. Behind the platter holder 33, on the left side, the soup bowl holder 3
7 are provided. The soup bowl holding section 37 is formed by arranging a plurality of square gates 38 inclined slightly rearward in the front-rear direction, and stands and holds a soup bowl between adjacent gates 38. The front and side of the platter holder 33, that is, the lower basket 31
Is a small plate holding portion 39.
The small plate holding portion 39 is provided with a gate 40 for holding the small plate with the outer frame of the lower basket 31.

The large plate holder 33 is arranged in front of the lower basket 31, and the bowl holder 35 and the soup bowl holder 37 are connected to the lower basket 31.
The rear plate is arranged in two rows on the left and right sides, and a large plate, a teacup and a soup bowl are accommodated side by side in the front-rear direction. Even if the lower basket 31 is long, tableware can be efficiently accommodated. In particular, since the upper basket 32 is arranged above the bowl holding unit 35 and the soup bowl holding unit 37, the platter holding unit 33 is arranged behind the lower basket 31 and the upper basket 32 is arranged above it. In comparison, the arrangement position of the upper cage 32 can be lowered. Therefore, the height of the dishwasher 1 main body can be reduced.

A resin stand 41 for accommodating chopsticks, spoons and the like is provided between the large plate holder 33 and the soup bowl holder 37.
Is detachably attached. Since the stand 41 is disposed on the left side of the lower basket 31, that is, on the side opposite to the heater 23, it is possible to prevent the chopsticks and the like accommodated in the stand 41 from falling onto the heater cover 26. The left side surface of the stand 41 is close to the left outer frame of the lower basket 31. The outer frame is taller than the stand 41 corresponding to the stand 41 and slightly wider than the depth of the stand 41. Form a wide gate 42. The gate 42 prevents the chopsticks and the like stored in the stand 41 from falling out of the lower basket 31.

A frame 43 is provided at the rear of the lower cage 31 so as to surround the rear of the upper cage 32. Frame 43
Consists of a right frame 43a, a left frame 43b, and a rear frame 43c.
The upper basket 32 is a front basket 44 constituting a front part of the upper basket 32.
And a rear basket 45 constituting the rear part. Rear basket 45
Is supported by the support member 46 formed from the rear frame 43c in a slightly inclined state so that the rear side is lower in the installed state. Further, it can be pivoted upward from the installed state with the support member 46 as a fulcrum. The front basket 44 is supported by a support portion 47 provided at the front end of the rear basket 45, and in the installed state, similarly to the rear basket 45, the rear side is slightly inclined so as to be lower. Further, it can be rotated upward with the support portion 47 as a fulcrum.

FIG. 14 is a side view of the main part of the tableware basket 30 showing the upper basket 32 closed. The upper basket 32
The upper basket 32 may be an obstacle when a large tableware is placed under the container. In this case, the upper basket 32 can be stored. That is, first, the front cage 44 is rotated and overlapped on the rear cage 45. Next, the rear cage 45 is rotated in a state where the front cage 44 overlaps, and leans on the rear frame 43c. After folding the upper basket 32 in two, the rear frame 4
3c, and is held upright.

Referring again to FIG. 12, a gap C is provided between the right end of the upper cage 32 and the right outer frame (right frame 43a). This gap C allows the upper part of the cutting board to escape when the cutting board is stored in a state where the cutting board is set up on the right end of the lower basket 31. In the rear basket 45 of the upper basket 31, the cups are arranged in two rows, and four standard cups are arranged in one row. The rear basket 45 can accommodate a total of eight standard cups. The rightmost cup in each row is in a state where a part of the cup protrudes into the gap C, but can be stably supported because the side portion of the cup can be supported by the right frame 43a. When a cutting board is accommodated in the gap C,
The rightmost cup cannot be placed and only six cups can be stored.

On the other hand, since there is no frame 43 on the left and right sides of the front cage 44, frame portions 48 are provided on both side ends of the front cage 44.
Therefore, in the front basket 44, the gap C cannot be used even if the cutting board is not housed. Therefore, four cups cannot be placed like this with the rear basket 45 as it is. Here, the right end of the front cage 44 is extended so as to slightly project toward the front side, and an extension 49 is provided. And
The rightmost cup is shifted slightly ahead of the cup on the left side to accommodate it (see FIG. 4). Thus, four cups can be arranged without using the gap C portion.

In the dishwasher 1 of this embodiment, the door 2
Is opened, the tableware basket 30 can be pulled out to the back side of the door 2. Therefore, rollers 50 are provided at the four corners at the bottom of the lower basket 31. Further, at the lower part of both side walls of the washing tank 5, a rail portion 51 for supporting the tableware basket 30 in the washing tank 5 and rolling the roller 50 is provided (see FIG. 7). The structure of the door 2 will be described later. FIG. 15 is a front vertical sectional view showing a state in which dishes are stored in the dishwasher 1. 2 and 1
Referring to 5, in lower basket 31, tableware is accommodated in soup bowl holding portion 37 in a relatively dense state. this is,
This is because in the soup bowl holding section 37, the soup bowls with a deep bottom are arranged with a small gap. On the other hand, tableware is accommodated in the bowl holding unit 35 in a relatively sparse state. This is because tea bowls having a shallower bottom than the soup bowls are arranged with a certain margin (gap). The bowl holding section 35 has a margin in consideration of accommodating bowls.

Therefore, in the upper basket 32, the water sprayed from the rear nozzle arm 17 sufficiently reaches the cup stored above the bowl holding section 35, that is, on the right side. That is, there is a possibility that water may not sufficiently reach the cup stored on the left side. In the dishwasher 1 of the present embodiment, an auxiliary nozzle body (fixed nozzle arm) 52 is provided at the lower part of the inner surface of the left side wall of the washing tank 5 in order to wash the cup accommodated on the left side of the upper basket 32.

FIG. 16 is a side longitudinal sectional view for explaining the auxiliary nozzle body 52. As shown in FIG. This auxiliary nozzle body 52
Has an elongated shape extending in the front-rear direction, and is provided with four nozzles 52a having injection ports on the front surface. These nozzles 52a spray water toward a cup housed on the left side of the upper basket 32. More specifically, the auxiliary nozzle body 5
2 extends from the back side of the washing tank 5 to around the center in the front-rear direction, and three of the four nozzles 52a on the rear side have one injection port, and water is supplied only toward the upper cup. In contrast to the jetting, the front nozzle 52a has two jets, and jets water not only above but also to a stand 41 arranged diagonally forward.

Referring to FIGS. 15 and 16, a connection port 53 is provided at the rear end of the auxiliary nozzle body 52, and one end of a water pipe 54 is connected to the connection port 53. The other end of the water pipe 54 is connected to the upper surface of the rear end of the nozzle base 13. The water supply pipe 54 has a connection port 7 with the nozzle base 13.
3, once extending upward along the inner surface of the rear wall of the washing tank 5, that is, along the rear surface 61 b of the panel 8, extending horizontally to the left, and connecting ports 53 of the auxiliary nozzle body 52 at the left rear corner of the washing tank 5. Is connected. Thereby, water can be supplied from the nozzle base 13 to the auxiliary nozzle body 52 via the water supply pipe 54. In particular, since the water pipe 54 is provided along the rear surface 61b of the panel 8, the water pipe 54 and the auxiliary nozzle body 52 can be arranged without providing a space for the water pipe 54. The water pipe 54 has a small thickness so as not to take up space.

The auxiliary nozzle body 52 and the water pipe 54 may be formed integrally. In this case, the water pipe 54 and the auxiliary nozzle body 52 can be easily installed in the cleaning tank 5. In this manner, the storage state of the tableware in the lower basket 31 is dense, and the auxiliary nozzle body 52 places the upper basket 32 in the area (left area) where water from the rear nozzle arm 17 is hard to hit because it is above this area. Since the water is sprayed, the cup disposed in this portion can be sufficiently washed. Therefore, the dishwasher 1 with high detergency can be provided.

Further, as shown in FIG.
2 is arranged with a gentle upward inclination from the back side to the front side so as to correspond to the inclination of the upper cage 32. As a result, water can be sprayed straight on the cup accommodated on the left side of the upper basket 32, so that the cup can be suitably washed and the auxiliary nozzle body 5 can be sprayed.
After water is sprayed by the method 2, water can be prevented from remaining inside the water. Further, since the water supply pipe 54 is disposed in the cleaning tank 5, even if the connection and the seal with the auxiliary nozzle body 52 and the nozzle base 13 are insufficient, even if water leaks from this part, It only leaks into the washing tank 5 and does not leak outside the machine. In addition, since the water pipe 54 is connected to the auxiliary nozzle body 52 on the side wall of the washing tank 5 so as to be turned around from the rear wall of the washing tank 5, the water pipe 54 may cross the rail portion 51. There is no hindrance to the drawer and storage operations of the tableware basket 30 due to the water pipe 54.

The connecting position of the water supply pipe 54 with the nozzle base 13 is set near the water supply nozzle 19, and the water supply pipe 54 and the water supply cover 21 are integrally formed of resin. . Referring to FIG. 3, the door 2 that covers the front surface of the cabinet 3, that is, the tableware insertion port 6.
The lower end is supported to be openable and closable, and opens forward with the lower end as an axis. A handle 55 is provided at the upper center of the front surface of the door 2, and exhaust ports 56 are provided on both sides of the handle 55.

FIG. 17 is a plan view showing the structure of the back surface 2a of the door 2 with the door 2 opened. When the tableware basket 30 is pulled out to the back surface 2a of the door 2 when the door 2 is opened, the rollers 5
1 is provided. The roller receiver 57 extends in the vertical direction of the door 2. The roller receiver 57 is formed by projecting the rear surface 2a at the end of the door 2 backward from the center.

FIG. 18 is a schematic view of the dishwasher 1 in a state where the tableware basket 30 is pulled out. As shown in FIG. 18, when the tableware basket 30 is completely pulled out, the roller 50 in front of the tableware basket 30 is mounted on the roller receiver 57, and the rear roller 50 is mounted on the rail portion 51. Referring to FIG. 17 again, on the upper surface of the rear surface 2 a of the door 2, the exhaust port 56 is formed by the rear surface 2 a of the door 2 and the exhaust cover 58.
An exhaust air passage 59 is formed. This exhaust air path 59
Has a substantially U-shape connecting both exhaust ports 56, and an outlet 60 for wind from the cleaning tank 5 is provided on the lower surface at the center. Exhaust gas from the cleaning tank 5 enters the exhaust air passage 59 through the outlet 60, passes through the exhaust air passage 59, and is exhausted from both exhaust ports 56 to the outside.

Here, since high-temperature steam is discharged from the exhaust port 56 during drying, a certain distance must be provided between the exhaust port 56 and the handle 55 from the viewpoint of safety. For this reason, in the case of the dishwasher 1 according to the present embodiment having a small width, the exhaust port 56 is inevitably moved toward the end of the door 2 because the width of the door 2 is small. In this case, as shown in FIG. 11, on the back surface 2 a of the door 2, both end portions 58 a of the exhaust cover 58 protrude into the roller receiver 57. In the present embodiment, the surface of the exhaust cover 58 and the surface of the roller receiver 57 are substantially flush with each other.
Since both end portions 58a of the pair 8 also serve as the roller receiver 57, it does not hinder the tableware basket 30 from being pulled out to the back surface 2a of the door 2.

As described above, the dishwasher 1 according to one embodiment of the present invention.
Has been described, but the present invention is not limited to the above embodiment, and various changes can be made within the scope of the matters described in the claims. For example,
The auxiliary nozzle body 52 is not limited to a slim dishwasher,
It can be applied to a conventional cubic type dishwasher.
