Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a base structure in a steam ejector.

Generally, this type of steam jet device supplies water to a heated vaporization chamber and vaporizes it, and this is to prevent some of the hot water that has not been sufficiently vaporized in the vaporization chamber from directly flying out of the steam jet hole. , the steam passage from the vaporization chamber to the steam outlet is lengthened. As a means for this purpose, a partition plate was interposed between the base and the base lid. The present invention solves the problem of hot water splashing out by making the steam passage longer in such a steam ejector without increasing the number of components.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a base having a steam jet hole 2, and 3 a base lid attached to the base 1 via a packing 4, which has a built-in heater 5. Reference numerals 6 and 7 indicate partition plates interposed between the base 1 and the base lid 3, the peripheral edges of each of which are sealed to each other via the packing 4, and one of the partition plates 6 and the base lid separates the vaporization chamber 8. At the same time, a steam passage 9 is defined between the partition plates 6 and 7 and between the partition plate 7 and the base.

Reference numeral 10 denotes a tube that supplies water in the tank 11 to the vaporization chamber 8, and is provided with an on-off valve 13 that controls the water forcibly supplied by the pressurizing device 12.

A pipe 14 is connected to the tube 10 and discharges steam to one end of the vaporizing chamber 8, and a steam hole 15 of the partition plate 6 is provided at a position away from the opening of the pipe 14.

Reference numeral 16 denotes a protruding wall extending inward from the periphery of the packing 4 to form a detour 17 between the partition plates 6 and 7, and is approximately U-shaped, and the steam hole 15 is located on the outside of the protruding wall. The partition plate 7 is provided with a through hole 18 through which the partition plate 7 is inserted.

The steam generated in the vaporization chamber 8 passes through a detour 17 formed between the partition plates 6 and 7 by the protruding wall 16 of the packing 4 from the steam hole 15, reaches the steam outlet 2 through the through hole 18, and is discharged to the outside. . As described above, the present invention extends inward a part of the packing that seals the base and the base lid between the plurality of partition plates interposed between the base and the base lid, and the gap between the partition plates is By dividing the inside and outside to form a steam detour, the steam passage can be made sufficiently long without increasing the number of components, and the problem of hot water splashing out can be solved.

It also has the advantage of good assembly workability and can be obtained at low cost.

Claims (1)

[Claims] 1. A base having a steam outlet, a base lid attached to the base via packing, and a plurality of partition plates interposed between the base and the base lid to define a vaporization chamber and a steam passage. , the packing is provided with a projecting wall extending between the plurality of partition plates, and the projecting wall divides the gap between the partition plates into inner and outer parts to form a detour for steam.
