[0003] At present, the existing water gas separation box is usually two upper and lower arranged shell bodies, the shell body cooperation surrounds water gas separation cavity, the water inlet, the water outlet and the gas outlet that are in communication with the water gas separation cavity are respectively arranged on the shell body, high temperature water flows through the water inlet into the water gas separation cavity, and before flowing out from the water outlet, water gas separation needs to be carried out first. However, it is found in actual application process that some water remains in the water gas separation cavity, after instant machine stops working, the residual water in the water gas separation cavity will continue to drip out through the water outlet of the water gas separation box, which causes dripping at the water outlet of instant machine, and the user experience is poor. UTILITARY MODEL CONTENTS

[0004] The technical problem to be solved by the utility model is to provide a water gas separation box to solve the problem of water outlet dripping.

[0005] In order to solve the above technical problem, the utility model adopts the following technical scheme: a water gas separation box, comprising a box body and a box cover, the box cover is covered on the top of the box body, to form a water gas separation cavity with the box body, the water gas separation cavity has a water outlet at the bottom and a water inlet at the side, the water outlet is arranged on the box body, and a lower surrounding rib extending upwards around the water outlet is further arranged on the box body, the upper surrounding rib extending downwards is arranged on the box cover, the upper surrounding rib is arranged on the outer circumferential side of the upper part of the lower surrounding rib, to form a inverted U type siphon channel for connecting the water gas separation cavity and the water outlet. The technical scheme has the following technical effects:

[0006] The utility model discloses a lower enclosing rib and the upper enclosing rib around the outer circumferential side of lower enclosing rib form the siphon channel of inverted U type to be used for connecting water gas separation chamber and water outlet, and the water inlet end of siphon channel is connected with water gas separation chamber, and the water outlet end of siphon channel is connected with water outlet. When the water level in water gas separation chamber is higher than the top of lower enclosing rib, the different liquid level of water gas separation chamber and siphon channel will generate pressure difference to form siphon effect, and the water flow in water gas separation chamber will flow to water outlet through siphon channel under siphon effect, and the water around water outlet flows through siphon channel, which improves the water outlet speed of water gas separation box and improves the water type of water outlet to a certain extent, until the water level in water gas separation chamber is lower than the top of lower enclosing rib, and water outlet stops water, at this time, the water flow in water gas separation chamber cannot enter water outlet through lower enclosing rib, which can avoid subsequent dripping of water outlet and improve the use experience of user. Because the upper enclosing rib is arranged on the box cover, and the lower enclosing rib is arranged on the box body, in the production and assembly process, the staff only needs to assemble the box cover to the box body, and the upper enclosing rib and the lower enclosing rib can jointly form the siphon channel, that is, the siphon channel can be formed without additional parts and assembly steps, which simplifies the structure of water gas separation box, improves the reliability of water gas separation box, reduces the production and assembly steps and reduces the assembly difficulty.

[0007] In the water-gas separation box, the top of the box body is provided with an air outlet pipe higher than the lower enclosing rib, the air outlet pipe vertically extends upward to enclose an air outlet channel penetrating through the bottom of the box body, and the top of the water-gas separation chamber is communicated with the outside through the air outlet channel. By arranging the air outlet pipe enclosing the air outlet channel to be higher than the lower enclosing rib, when the high-temperature liquid passing through the water-gas separation chamber flows to the water outlet, the high-temperature water vapor generated can be simultaneously discharged to the outside through the air outlet channel, the water-gas separation effect is good, and the operation is more stable and reliable.

By arranging the water-gas separation chamber to be jointly formed by the upper cavity on the box cover and the lower cavity on the box body, the cross-sectional area of the water-gas separation chamber can be reduced while meeting the water passing demand of the water-gas separation chamber, thereby reducing the water amount of the residual water in the water-gas separation chamber. By increasing the water-gas separation chamber, the liquid level difference between the water-gas separation chamber and the siphon channel can be further increased under the same water passing amount, thereby increasing the pressure difference between the water inlet end and the water outlet end of the siphon channel and the initial gravitational potential energy of the liquid, enhancing the siphon effect, improving the overall water outlet speed of the siphon channel and the water outlet, and avoiding the accumulation of a large amount of water flow in the water-gas separation chamber to cause the rapid rise of the water level.

[0009] In the water-gas separation box, the water inlet is arranged through the cover of the upper cavity side, and the height of the water inlet is lower than the top of the gas outlet channel. By arranging the water inlet on the cover of the upper cavity side, the initial gravitational potential energy of the water flow entering the water-gas separation cavity can be further increased, the siphon effect can be further enhanced, the overall water outlet speed of the water outlet can be improved, and the height of the water inlet is lower than the top of the gas outlet channel, so that the water flow entering the water-gas separation cavity through the water inlet cannot fall into the gas outlet channel, and part of the water flow in the water-gas separation cavity is prevented from flowing out through the gas outlet channel.

[0010] In the water-gas separation box, a water baffle is further arranged in the upper cavity, and the water baffle is vertically extended downward from the top surface of the upper cavity to separate the water inlet and the upper part of the gas outlet pipe. The water baffle is arranged between the water inlet and the upper part of the gas outlet pipe to prevent the water flow entering the water-gas separation cavity through the water inlet from impacting the pipe wall of the water outlet pipe, thereby preventing the water flow from splashing into the gas outlet channel or causing deformation of the water outlet pipe.

[0011] In the water-gas separation box, the box body below the water inlet is protruded into the water-gas separation cavity to form a water guide step below the water inlet for guiding the water flow to the siphon channel. The water guide step guides the water flow falling from the water inlet to the siphon channel, and the water flow speed to the siphon channel can be further improved through the water guide step, thereby improving the water flow speed out of the water outlet and ensuring stable and fast water outlet of the water outlet.

[0012] In the water-gas separation box, the lower surrounding rib is in an integrated structure with the box body, and the lower surrounding rib is located at the lowest part of the water-gas separation cavity. The water flow in the water-gas separation cavity flows to the water outlet surrounded by the lower surrounding rib, and excessive water accumulation in the water-gas separation cavity is avoided.

[0013] In the water-gas separation box, the position opposite to the water outlet of the cover is recessed downward to form a mounting portion, and the upper surrounding rib is arranged on the bottom surface of the mounting portion. Through the arrangement of the mounting portion, the overall height of the siphon channel is reduced to discharge the water flow in the water-gas separation cavity as much as possible and reduce the height of the residual water in the water-gas separation cavity.

[0014] In the water-gas separation box, the top of the box body is provided with an annular sealing groove, and the bottom of the cover is provided with an annular sealing rib inserted into the annular sealing groove. When the cover is closed on the box body, the annular sealing rib is vertically inserted into the annular sealing groove to enhance the sealing between the box body and the cover and prevent water leakage at the connection between the box body and the cover.

The outer side wall of the water blocking rib abuts against the inner wall of the box body to block the gap between the box body and the cover, thereby further enhancing the sealing effect between the box body and the cover.
