Problems solved by technology

[0004] The main defects of the existing steam valve include: 1. The fan blades are arranged horizontally, and the resistance caused by the steam to push the fan blades to rotate is large, which is not conducive to the normal discharge of steam; 2. The steam directly impacts the fan blades, and viscous liquid and other substances are easy to block the rotation shaft of the fan blades , causing the fan blades to stick; 3. The backflow pad located in the lower right corner can only be pushed away when the backflow liquid reaches enough weight, and the backflow speed is slow, resulting in viscous liquid sticking to the inside of the steam valve, which is difficult to clean

Embodiment 1

[0046] This embodiment discloses a steam valve assembly and a steam heating device including the steam valve assembly. like figure 2 and image 3 As shown, the steam valve assembly includes a valve cover 1, a valve seat 2 and a bubble-breaking fan blade 3. The bubble-breaking fan blade 3 is arranged in the steam chamber 4 surrounded by the valve cover 1 and the valve seat 2. The bubble-breaking fan blade 3 includes The rotating shaft 31 and the blade 32 arranged on the outer wall of the rotating shaft 31, the rotating shaft 31 is vertically arranged between the valve cover 1 and the valve seat 2, and the blade 32 is arranged obliquely with respect to the axis of the rotating shaft 31 and has a certain degree of twist. In order to prevent steam leakage from the periphery of the steam valve assembly, a sealing ring 6 is provided between the valve cover 1 and the valve seat 2 .

[0047] The bubble-breaking fan blade 3 is arranged vertically, and when the liquid-laden steam blo...

Embodiment 2

[0072] This embodiment discloses a steam valve assembly and a steam heating device including the steam valve assembly, the structure of which is basically the same as that of Embodiment 1. The difference is that if Figure 20 As shown, the inner surface of the valve cover 1 is provided with a fixing sleeve 14, which is used to replace the fixing pin 13 in the first embodiment. Correspondingly, as Figure 21 and Figure 22 As shown, a columnar structure 36 is formed on the top of the rotating shaft 31 of the bubble breaking fan blade 3 . like Figure 23 As shown, the columnar structure 36 is inserted into the fixing sleeve 14 to realize the installation of the bubble-breaking fan blade 3 .

[0073] exist Figure 22 Among them, the diameter of the lower part of the rotating shaft 31 shrinks at an appropriate position to form a stepped structure, and the top surface of the mounting part 22 of the valve seat 2 abuts against the lower surface of the stepped structure, so that ...

Abstract

The invention discloses a steam valve assembly and a steam heating device, and belongs to the technical field of kitchenware. The steam valve assembly and the steam heating device are designed for solving the problem that an existing steam valve is likely to cause excessive steam pressure. The steam valve assembly includes a valve cover, a valve base and a bubble breaking fan blade; the bubble breaking fan blade is arranged in a steam cavity which is defined by the valve cover and the valve base, and includes a rotating shaft and blades arranged on the outer side wall of the rotating shaft; the rotating shaft is vertically arranged between the valve cover and the valve base, and the blades are arranged obliquely relative to the axis of the rotating shaft. The steam heating device includesthe steam valve assembly. The steam valve assembly and the steam heating device effectively break bubbles in steam by pressing or hitting, and meanwhile cannot produce excessive resistance to steam flowing; the steam without viscous liquid can flow freely among the blades, and it is ensured that the pressure in the steam heating device is always in a safe range.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a steam valve assembly and a steam heating device comprising the steam valve assembly. Background technique [0002] The working principle of the steam heating device is to use high-pressure steam to shorten the cooking time, and it is widely used in the field of kitchen utensils, such as pressure cookers. High-pressure steam has a lot of energy. If a certain amount of steam is not discharged in time during use, the container may explode. Therefore, the existing steam heating devices are equipped with steam valves of various structures. [0003] When the steam heating device is steaming rice porridge and other substances that will produce viscous liquid, the direct discharge of steam will cause part of the viscous liquid to overflow directly from the air outlet along with the steam, resulting in bubbling in the steam valve and affecting the normal discharge of steam. In...
