[Action] The steam that is trapped in the washing room by washing and rinsing touches a hydrophilic shielding plate arranged near the ceiling of the outer box, and a sufficient amount of dew water is retained on the shielding plate.

Therefore, water drops do not fall on the outer surface of the opened door.

The condensed water that has flowed out of the shielding plate after being saturated is surely dropped into the cleaning room through the gutter.

By closing one end of the gutter and allowing the water from the gutter to flow from a desired direction, the operator can be prevented from being exposed to water in the case of a pass-through dishwasher.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

1 is a food-type dishwasher,
Inside the main body 2 covered with a stainless steel panel, there is provided a washing tank 3 integrally formed with a water receiving portion 3a at an upper portion. The washing tank 3 has an overflow pipe 4
And a washing pump 8 for jetting high-temperature washing water from inside the washing tank 3 from the connecting pipe 5 through the washing pipe 6 to the washing nozzles 7, 7. 9,
Reference numeral 9 denotes a rinsing nozzle (not shown), which is supplied with high-temperature water by a rinsing pump and rinses the dishes after the washing is completed. Reference numeral 11 denotes a filter.

The cleaning chamber 12 in which the cleaning nozzles 7 and 7 and the rinsing nozzles 9 and 9 are rotatably arranged is provided with a main body 2.
A housing provided at an upper part, that is, an outer box 14 having an opening 13 for storing and taking out an object to be washed on the front surface, a canopy-shaped inner box 15 provided in the outer box 14,
And a hood-shaped door 16 that opens and closes. The inner box 15 is divided into upper and lower parts by applying the end of the rear part which is inclined downward and bent to the back wall of the outer box 14 to prevent washing water and rinsing water from scattering toward the outer box 14. I have.

The door 16 is pivotally supported by a shaft 18 horizontally mounted at a position in front of the outer box 15 and can be freely opened and closed and rotated by a handle 19, and is opened upward from below. And into the space 10 between the inner box 15 and the outer box 14 as shown in FIG.

Now, when the door 16 is closed as shown in FIG. 1 and washing and rinsing are performed using hot water, steam is trapped not only in the washing room 12 but also in the space 10. Under the top plate 14, a shielding plate 20 made of a hydrophilic material is inclined downward and downward toward the front and rear so that the steam will not cool down and form condensation on the top plate 14A of the outer box 14. It is arranged as. The shielding plate 20 is made of a porous resin member or a stainless steel plate and is manufactured by pickling and forming an uneven surface on the surface, and is made to easily absorb moisture and sufficiently contain the inside. It is possible. Reference numeral 21 denotes a gutter formed inside the lower end of the front end wall 14B of the outer box 14 corresponding to the tip of the front plate portion 20a among the plate portions inclined before and after the shield plate 20, and covers the entire width of the shield plate 20. Shield plate 20
When the water condensed on the front plate 20a is saturated, water droplets flowing through the front plate 20a are collected.

As shown in FIG. 4, both ends of the gutter 21 are opened to form outlets 22 and 22 for the condensed water droplets.
The front and rear end portions 2 are used as a downflow path so that they flow down into the cleaning chamber 12 and are collected.

Also, the rear plate portion 20b of the shielding plate 20 which is rearwardly inclined.
The tip is close to the back wall 14c of the outer box 14, and when the dew condensation is saturated, the water flowing along the rear plate portion 20b flows down along the back wall 14c from a slight gap with the outer box back wall 14. Then, it is also collected in the cleaning chamber 12.

A gutter 24 is provided inside the lower end of the door 16 for storing water scattered at the time of cleaning, and communicates with the gutter 24 to discharge water in the gutter 24 when the door 16 is opened.
2 A pair of side gutters 25 are also provided so as to be guided to the rear to prevent water dripping from the front of the door 16 when the door 16 is opened. Reference numeral 26 denotes a rack which stores the tableware 27 or the like to be washed by leaning on the rack and which is manually put in and out of the washing room 12.

With the above arrangement, the rack 26 on which the dishes 27 are mounted is arranged at a predetermined position in the washing room 12, the door 16 is closed,
When a washing switch (not shown) is pressed, the washing pump 8 is driven, and washing water pumped from the washing tank 3 is ejected from the ejection holes while rotating the washing nozzles 7, 7, and the tableware 2 is washed.
7. Wash 7 After the cleaning, hot rinsing water is sprayed from the rotating rinsing nozzles 9, 9 to perform rinsing.

When washing and rinsing are performed in this manner, steam that enters the space 10 between the outer box 14 and the inner box 15 condenses and adheres to the hydrophilic shielding plate 20. Then, the dew water is absorbed and spread over the entire surface of the shielding plate 20. Then, even if the condensed water becomes saturated, it separates back and forth and flows down along the slope of the shielding plate 20,
The water drop flowing forward is received by the gutter 21 and thereafter the gutter 21
While flowing down from both ends into the cleaning chamber 12, water droplets flowing backward travel down the back wall 14 c of the outer box 14 and are also collected into the cleaning chamber 12.

For this reason, since water droplets do not fall on the upper surface of the opened door 16, the problem that water splashes when the door 16 is opened and closed and wets the floor can be easily solved.

Next, the left and right sides of the washing room are opened, and the rack containing the dishes to be washed is put in from one opening and washed, and then the rack is taken out from the opposite opening to improve the usability. Another embodiment to which the present invention is applied in the case of a machine will be described.

As shown in FIGS. 5 and 6, the outer box 14 provided above the main body 2 is opened on both left and right sides, and the door 16 of the first embodiment and the rotation of the same mechanism correspond to each opening. A left door 16A and a right door 16B that open and close are provided.

Then, tables 31 and 32 are arranged on the left and right sides of the main body 2, respectively, and the rack 26 containing the tableware 27 is placed on the tables 31 and 32 so that the rack 26 can be moved in and out of the washing room. The operation can be performed from an arbitrary direction (the direction indicated by arrows A and B).

Here, an operation panel section 33 having a washing switch, an indicator light, and the like is provided on a front surface 2a of the main body 2, and the dishwasher 1A is installed at the rear of the main body 2 as shown in FIG. 2b is often used against wall 34.

Therefore, when the gutter 20 provided on the outer case 14 and receiving the water flowing from the hydrophilic shielding plate 20 has both ends open as in the first embodiment, a person operates a switch or the like. Water also flows down on the front side of the main body 2 having the operation panel section 33, which is not preferable from the viewpoint of operation.

Therefore, as shown in FIG. 7, the opening at the front end of the gutter 20 is closed 35, and the outlet 22a is only at the rear end.
The water from the gutter 21A is pressed against the wall 34 so as to flow from the rear side of the main body 2 without having to worry about water being hit by hand.

[0028]

As described above, according to the present invention, the housing at the upper part of the main body, which is capable of rotating and storing the hood-shaped door for opening and closing the washing chamber, is provided with a hydrophilic shielding plate below the top plate. Is provided at an appropriate angle, so that when using hot water at the time of cleaning etc., steam will come out and dew condensation on the top plate will be absorbed by the shielding plate, and water drops from the ceiling outside the opened door as in the past. Can prevent falling and sticking. Therefore, it is possible to solve such a problem that the attached water scatters outside when the door is closed and wets the floor. Also, even if the dew water of the shielding plate is saturated and flows along the slope of the shielding plate, the water is collected in a gutter formed at the tip of the housing and dropped from both ends of the gutter into the washing room. It can be reliably collected without dropping to the outer surface or leaking out of the washing room. Furthermore, in the case of a pass-through type (double door type) dishwasher, the water from the gutter closes one end of the gutter so that the water flows out from a predetermined one, and the water flows from the side opposite to the side with the operation panel. It is possible to prevent water from being splashed on the person and improve usability.
