Abstract

PURPOSE:To cleanly wash the inside and the outside surfaces of a pan whose bottom is shallow and a pot whose bottom is deep in a short time by installing the upper nozzle so as to be turnable centering around a shaft so as to be attachable and detachable, and constituting the upper nozzle of a linear first nozzle and a Z-shaped second nozzle which are used selectively. CONSTITUTION:In a first nozzle 11, and the lower nozzle 12, an injection port 11a and an injection port 12a are opened, respectively. A Z-shape rod-like washing second upper nozzle 15 has an injection port 15a opened downward. In the lower basket 3, a pan 16 whose bottom is shallow is contained in a state that its port is turned downward, and by turning a first upper nozzle 11 by 180 deg. and turning downward the injection port 11a, washing is executed. As for the pan 16, a washing liquid is injected simultaneously to the outside and the inside surfaces, and washing is completed in a short time. In the lower basket 3, a pot 17 whose bottom is deep is contained by turning downward its port. A first upper nozzle 11 is drawn out of a connecting part 13, and an end part of a second upper nozzle 15 is inserted into the connecting part 13. As for the pot 17 whose bottom is deep, as well, the washing liquid is injected simultaneously to the inside and the outside surfaces, and washing is completed in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a device for cleaning tableware by spraying a cleaning liquid onto the tableware.

[Prior Art] FIG. 4 is a vertical cross-sectional view of a main part of a conventional dishwasher disclosed in, for example, Japanese Patent Publication No. 52-27940.

In the figure, (1) is a box body, in which an upper basket (2) and a lower basket (3) for storing tableware (not shown) to be washed are arranged. An upper cleaning nozzle (4) and a lower cleaning nozzle (5) each rotating in a horizontal plane are provided below, and each has a plurality of injection ports (4a).
(5a) is open upward. And both nozzles (4
) and (5) are both connected to the cleaning pipe (6).

A conventional dishwasher is configured as described above, and when the washing pump (not shown) is driven, the washing liquid is introduced from the washing pipe (6), and the washing liquid is introduced into the washing upper nozzle (4) and the lower washing nozzle (5).
At the same time, both nozzles (4) and (5) rotate, and the upper and (2)
) and the tableware stored in the lower part (3). After this washing, rinsing water or water is sprayed from the rinsing upper nozzle and rinsing lower nozzle (not shown), which are configured in the same way as the washing upper nozzle (4) and the lower rinsing nozzle (5), and the washing liquid adhering to the tableware is washed away. be dropped.

[Problems to be Solved by the Invention] In the conventional dishwasher as described above, both nozzles (4) are arranged at a predetermined interval in the height direction inside the box (1).
(5) sprays the cleaning liquid or rinsing water (water) upward onto the tableware, so when cleaning a deep-bottomed pot, the space between the two nozzles (4) and (5) is narrow. There is a problem in that it is difficult to thoroughly clean the inner and outer surfaces of the pan.

This invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide a dishwasher that can quickly and cleanly clean both the inner and outer surfaces of both shallow and deep pots. shall be.

[Means for Solving the Problems] A dishwasher according to the present invention has a rod-shaped upper nozzle and a lower nozzle arranged, and the upper nozzle is attached detachably and rotatably about its axis, The upper nozzle is composed of a linear first nozzle and a double-shaped second nozzle, which can be selectively used.

[Function] In this invention, the upper nozzle is detachably and rotatably mounted, and the linear first nozzle and the L-shaped second nozzle are connected to each other.
Since the nozzle can be selectively used, when cleaning a pan with a shallow bottom, use the first nozzle with the nozzle facing downward, and when cleaning a pan with a deep bottom, remove the first nozzle and use the second nozzle. Use it by replacing it with a nozzle.

[Embodiment Figures 1 to 3 are diagrams showing an embodiment of the present invention.
2 is an enlarged vertical sectional view of the n section of FIG. 1, and FIG. 3 is an explanatory diagram for use. Portions similar to those of the conventional device are designated by the same reference numerals.

In the figure, (o) and (12) are straight rod-shaped cleaning first upper nozzles and cleaning lower nozzles arranged below the upper basket (2) and the lower basket (3), respectively. has an injection port (lla), and the lower nozzle (12) has an injection port (12a).
) is open. (13) is a connection part provided at the tip of the cleaning tube (6), into which the end of the first upper nozzle (11) is inserted. (14) is provided in the connection part (13) and the first
This is an O-ring that contacts the end of the upper nozzle (1). Further, the lower nozzle (12) is fixedly connected to the cleaning pipe (6). (15) is a two-rod-shaped cleaning second upper nozzle, which has an injection port (15a) that opens downward, and its end is connected to the connection part (13) in the same way as the first upper nozzle (11). inserted. (16) is a shallow pot, and (17) is a deep pot. Note that the rinsing nozzle (not shown) is also configured in the same manner as described above.

In the dishwasher configured as described above, by properly using the first and second upper nozzles (11) and (15),
Cleaning is performed as follows.

■Usually, tableware is stored in the upper basket (2) and lower basket (3), and
Cleaning is performed with the injection port (lla) of the upper nozzle (11) facing upward.

■In the case of a shallow pot (16) As shown in Figure 1, place the shallow pot (16) in the lower basket (3).
6) with its mouth facing downward, and insert the first upper nozzle (
11) is rotated 180° to direct the injection port (lla) downward, and cleaning is performed. In this way, the cleaning liquid is simultaneously sprayed onto the inner and outer surfaces of the pan (16), and cleaning is completed in a short time.

■In the case of a deep-bottomed pot (17) Remove the upper basket (2) from the state shown in Figure 1, and as shown in Figure 3, place the deep-bottomed pot (17) with its mouth facing downward. Toward and accommodate. Then, the first upper nozzle (11
) from the connection part (13), as shown in Figure 3.
Insert the end of the second upper nozzle (15) into the connection part (13). In this way, the cleaning liquid is simultaneously sprayed onto the inner and outer surfaces of the deep-bottomed pot (17), and cleaning is completed in a short time.

[Effects of the Invention] As explained above, in this invention, a rod-shaped upper nozzle and a lower nozzle are arranged, the upper nozzle is detachably attached and rotatable about its axis, and the upper nozzle is attached in a straight line. It consists of a shaped first nozzle and a two-shaped second nozzle, and these can be used selectively, so cleaning a shallow pot can be done by using the first nozzle and pointing the injection port downward. ,
When cleaning a pot with a deep bottom, remove the first nozzle and replace it with the second nozzle.It has the effect of cleaning the inner and outer surfaces of both shallow and deep pots in a short time. be.
