Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dishwasher for washing and drying dishes.

2. Description of the Related Art The general structure of a conventional dishwasher will be described with reference to FIG. A washing tank 2 is disposed inside a main body 1 of the dishwasher, and washing water in the washing tank 2 is circulated by a washing water pressure pump 4 driven by a motor 3. During washing and rinsing, the washing water pumped by the washing water pressurizing pump 4 is jetted from a nozzle 5 provided in the washing tank 2, and collides with the dishes 7 arranged in an orderly manner in the dish basket 6 located above the nozzle 5. Wash and rinse. During drying, the steam in the washing tank 2 is exhausted from an exhaust port 9 provided in a door 8 that can be opened and closed, thereby drying the dishes 7.
10 is a heater for heating the washing water and heating it during drying.

Problems to be Solved by the Invention In such a conventional configuration, a relatively large exhaust port 9 must be provided in order to efficiently exhaust the steam in the cleaning tank 2 to the outside of the machine during drying. Therefore, during washing or rinsing, the sound of washing water hitting the wall of the washing tank 2, the sound of the dishes 7 touching each other, etc. leaked from the exhaust port 9 communicating with the outside of the machine and was unpleasant to the ears. There is also the problem that a large amount of steam leaks from the exhaust port 9 during cleaning and rinsing, and as a result, the efficiency of heating the cleaning water is also reduced.

In view of the above-mentioned problems, the present invention aims to block sound during operation of a dishwasher and improve water heating efficiency.

Means for Solving the Problems In order to achieve the above object, the present invention includes a main body,
It is operated by a door that covers the front of the main unit that can be opened and closed, an exhaust port provided in the door, a lid that opens and closes the exhaust port, an elastic body that biases the lid in the opening direction, and the pump pressure of the cleaning water pressurizing pump. a lever, the pressure actuating body is disposed on the front side of the main body, the actuating part is movably protruded toward the door, and the actuating part opens and closes the lid; The lid is opened by operating the lid.

Function: With this configuration, the washing water pressurizing pump is operated during washing or rinsing, so that the operating rod of the pressure operating body is operated. The operating rod moves the lever to close the lid and close the exhaust port, so the sound inside the cleaning tank will not leak from the exhaust port. Furthermore, the steam generated when heating the cleaning water does not flow out of the machine, increasing the water heating efficiency.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIG. Note that this drawing shows an enlarged view of the main parts of the present invention, and since the other parts have the same structure as the conventional one, the same parts are given the same reference numerals and the explanation thereof will be omitted. In the figure, reference numeral 11 is an exhaust port provided in a door 12 that can be opened and closed, and a lid 1 that can be opened and closed is attached to this exhaust port 11.
3 is attached to the lid 13, and a lever 14 that moves in conjunction with the lid 13 is connected to the exhaust port 11 via a shaft 15.
A spring 16 provided outside biases the lever 14 toward the main body 17 side. A hole 18a is provided on the main body 17 side of the door 12 where the lever 14 is located.
On the other hand, on the main body 17 side, there is a pressure operating body 1 which is operated by the pump pressure of a wash water pressurizing pump (not shown).
9 is provided, and the pressure of the wash water pressurizing pump is transmitted through a communication pipe 20. The actuating part 21 of the pressure actuating body 19 is formed into a rod shape, and the door 17 of the main body 17 is
It is configured to protrude through a hole 18b provided on the side. The holes 18a and 18b provided in each of the door 12 and the main body 17 are configured to be in opposing positions when the door 12 is closed.

In the above configuration, when washing or rinsing is performed, the washing water pressure pump is operated, and the pump pressure is transmitted to the pressure actuating body 19 through the communication pipe 20, and the actuating part 21 is applied to the door 1 through the hole 18b of the main body 17.
2 side, pushes the lever 14 through the hole 18a of the door 12, overcomes the force of the spring 16, and closes the lid 13.
rotates around the shaft 15 and closes the exhaust port 11. In addition, in the figure, the solid line indicates the pressure actuating body 19.
The dashed line shows a state in which the pressure actuating body 19 does not operate and the exhaust port 11 is opened.

In this embodiment, the exhaust port 11 is always closed by the lid 13 when the cleaning water pressurizing pump is operated, so that the noise generated in the cleaning tank 22 is less likely to leak outside the machine. Not only can noise be reduced, but steam can also be prevented from leaking from the exhaust port 11 due to the heating of washing water during washing or rinsing, and the water heating efficiency can also be improved. Further, with the above configuration, in terms of appearance, only small holes 18a and 18b are visible in parts of the door 12 side and the main body 17 side, respectively, and the appearance does not become unsightly.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the door is provided with an exhaust port with a lid that can be opened and closed, and the main body side is operated by the pump water pressure of the washing water pressurizing pump. Since the structure is such that a pressure actuating body is provided to open and close the cover of the exhaust port according to the operation of the pressure actuating body, noise leaking from the exhaust port is reduced.
By preventing steam leakage from the exhaust port during cleaning and rinsing, it is possible to improve the efficiency of heating the cleaning water. Furthermore, since the exhaust port is opened and closed using a wash water pressurizing pump, which is indispensable for dishwashers, there is no need to provide a new drive source for opening and closing the lid, and a drop in productivity due to the addition of parts can be prevented.
