Gas stove

Abstract

The invention relates to a gas stove. The gas stove comprises a switch valve, wherein the switch valve comprises a valve body and a valve element rotatably arranged inside the valve body; the valve element is internally provided with an air inlet passage communicated with an air source; an inner ring fire air outlet hole and an outer ring fire air outlet hole penetrating through the side wall are formed in the side wall of the valve element, wherein the valve body, corresponding to the inner ring fire air outlet hole, is provided with an inner ring main air outlet passage and an inner ring fine tuning passage, and the valve body, corresponding to the outer ring fire air outlet hole, is provided with an outer ring main air outlet passage and an outer ring fine tuning passage. During the process of adjusting heat power, after the outer ring main air outlet passage and the outer ring fire air outlet hole are staggered, the outer ring fine tuning passage supplies gas continuously in a certain angle rotation range; after the inner ring main air outlet passage and the inner ring fire air outlet hole are staggered, the inner ring fine tuning passage supplies gas continuously, so that the whole gas flow control curve becomes more gentle, and the heat power of the gas stove is convenient for a user to control accurately.

Description

Technical field [0001] The present invention relates to a gas stove, in particular to an on-off valve of the gas stove. Background technique [0002] The on-off valve of the existing gas stove usually includes a valve body and a valve core. A tapered hole is opened in the valve body, and the valve core is rotatably assembled in the tapered hole of the valve body. The valve core is provided with an air inlet channel and an air outlet communicating with the air source. When in use, the user rotates the knob of the gas stove to drive the valve core to rotate to adjust the gas flow rate, thereby adjusting the firepower of the gas stove. As described in the background art of the Chinese utility model patent CN201262248Y, when the on-off valve of the existing gas stove is used to adjust the gas, the firepower changes from the point of maximum firepower to a large angle at the beginning, and the firepower does not change. Obviously, in the later stage, if it only rotates slightly, the...

Problems solved by technology

As described in the background technology of Chinese utility model patent CN201262248Y, when using the on-off valve of the existing gas stove to adjust the gas, when it is at the maximum firepower, it rotates at a large angle at the beginning, and the firepower does not change. Obviously, in the later stage, the firepower will decrease sharply if only slightly rotated in the later stage, which makes it difficult for users to control the firepower adjustment of the gas stove

[0003] The Chinese utility model patent CN201262248Y improves the spool structure of the on-off valve in an attempt to solve the above problems. This patent makes the air outlet and the air-inducing groove on the spool have irregular curved sections to overcome the existing switch The disadvantage that the flow curve of the valve is not smooth enough when adjusting the flow rate, but in practical applications, this structure does not control the flow rate precisely enough, and the control effect on that section of the flow rate that changes too fast (165° to 185°) during the adjustment process not obvious
