Abstract

PURPOSE:To clean a water level detecting room with simple constitution without executing a valve control, etc., and to maintain a water level detecting function by communicating a feed room and a water level detecting room to a washing room, and simultaneously, communicating the water level detecting room through a buffering means to the feed room. CONSTITUTION:A washing room 2 to circulate-jet a washing water, a feed room 5 to supply the washing water and a water level detecting room 6 to detect the water level in the washing room 2 are provided. The feed room 5 and water level detecting room 6 are communicated to the washing room 2, and simultaneously, the water level detecting room 6 is communicated through a buffering rib 14 to the feed room 5. Namely, the water level detecting room internal part can be washed away at each time of the feed, simultaneously, the supply water is made hydrostatic only with the buffering means, and the water level detecting function can be maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a dishwasher that washes tableware by lining the washing machine up to a predetermined position and circulating and spraying washing water.

(b) Conventional technology This type of dishwasher has a water level detection chamber connected to the washing chamber.
A 70-toggle switch is installed in this water level detection chamber.

However, with this method, debris may remain in the water level detection chamber after cleaning, causing problems such as abnormal operation of the float switch and generation of bad odors.

Therefore, what is shown in Utility Model Application Publication No. 58-11451 is as follows.
Washing water is supplied through a water level detection chamber to wash away debris.

e→ Problems to be Solved by the Invention However, in this conventional f11, since the float swings during the supply of washing water and it is difficult to detect the water level, the next water supply is performed through the water level detection chamber only at the initial stage by opening the valve alK. After that, we ask them to use the water inlet of the pond.

The present invention aims to clean the water level detection chamber with a simple configuration and maintain the water level detection function without performing valve control or the like.

B) Means for Solving the Problems The solution according to the present invention includes a cleaning chamber for circulating and spraying cleaning water, a water supply chamber for supplying the cleaning water, and a water level detection chamber for detecting the water level in the cleaning chamber. The cleaning chamber is connected to a water supply chamber and a water level detection chamber, and the water supply chamber is connected to the water level detection chamber via a buffer means.

(E) Function When water is supplied, the cleaning water is divided into the cleaning chamber and the water level detection chamber, but the cleaning water that goes to the water level detection chamber is buffered by lips, cushions, etc. The water washes the water level detection chamber relatively quietly and enters the cleaning chamber from the communication port O with the cleaning chamber.Then, the water level in the cleaning chamber rises and is transmitted to the water level detection chamber via the communication port. Even around this time, the supplied water is flowing into the water level detection chamber without ripples, and the water level detection means is extremely unlikely to cause chattering.

(f) To explain based on the example drawings, the machine frame 1fl of the dishwasher,
A washing chamber 2 is provided inside, and a curved tableware entrance/exit of the washing chamber 2 is opened and closed by a door 6, and both an operating section and an auction section are disposed at the lower part of the front surface. A cleaning/draining pump 4 is disposed below the cleaning chamber 2 of the machine frame 1, and a water supply chamber 5 and a water level detection chamber 6 are placed adjacent to each other at the rear of the cleaning chamber 2.
A ventilation chamber 7 is disposed at the rear upper part of 2.

A #''11 rotation injection nozzle 8 is installed in the center of the cleaning chamber 2, and a heater 9 is installed in the bottom 1 fl of the submerged cleaning chamber 2.

The cleaning/drainage pump 4 sucks the cleaning water by scrubbing the filter 10, and discharges it to the injection nozzle 8 during cleaning rotation (forward rotation) and to a drainage hose (not shown) during drainage rotation (reverse rotation). A passage switching valve is provided as necessary.□ The water supply ¥5 and the water level detection chamber 6 communicate with each other via the water supply port 11 and the communication port 12 for the cleaning ¥2, respectively.
A buffer lip 14 is provided between the water level detection chamber 6 and the water level detection chamber 6, leaving a diversion port 13. The water supply chamber 5 expands in the direction away from the group force protection buffer lip 14 in a diagonal direction with respect to the portion 1013, and this expanded portion is inclined toward the buffer lip 14 and the water supply port 11, and this portion VcVi A water supply pipe 16 with a water supply valve 15 removed is made to face downward. Next, two floats 17 and 18 are arranged in the water level detection chamber 6, and a predetermined position switch 19 and a different potential switch 20 which are operated by the floating of each float 17 and 18 are provided.

When supplying water during the washing or rinsing process, first turn on water supply valve 1.
5 is opened, but city water supplied from the water supply pipe 16 flows into the room from one corner of the water supply chamber 5 and flows to the buffer lip 14. Then, a part of the water that is deflected here, goes to the water supply port 11, is supplied to the cleaning chamber 2, and flows along the n1 lip 14 flows into the water level detection chamber 6 from the diversion port 13. Since the inflowing water moves in a crank shape, it becomes still water, and it spreads over almost the entire area inside the water level detection chamber 6 and washes it.
2 to the cleaning room 2. 21- is a rectifying piece provided at the water supply port 11 and the communication port 12.

In this way, the water supply into the cleaning room progresses, the water level rises, and each 70)'17.18 floats to the predetermined position.
The predetermined position switch 19 creates VJ. Then, the water supply valve 15
is closed and a cleaning or rinsing process is performed. Even just before reaching the predetermined position, the water supplied from the branch stream 013 is still water, so the oscillation rIJ of the floats 17 and 18 is small.

The heater 9 is used both for heating the cleaning water (rinsing water) and for heating the drying air. The blower 22 in the air blower ¥7 is outside.
X is supplied into the cleaning chamber 2 as dry air. The supplied outside air is heated by the heater 9, mixed with the drying air, used for drying, and then discharged outside the machine.

(G) Effects of the Invention According to the present invention, the inside of the water level detection chamber can be flushed out every time water is supplied, and the supplied water can be made static using only the buffer means, thereby improving the water level detection chamber! ! This allows us to provide a clean and high-performance dishwasher.
