Description

A new type of gas stove

technical field

The utility model relates to a novel gas stove.

Background technique

Gas stoves are common production and living appliances in modern society. There are many types of gas stoves, including gas stoves that use liquefied petroleum gas as a heating energy source, and gas stoves that use combustible gases such as coal gas, natural gas, or biogas as a heating energy source.

Traditional gas stoves basically include a gas burner, an ignition device and a gas input control device; modern gas stoves further include safety devices such as flameout protection. The basic structure of a gas cooker is generally as follows: the main components of the gas burning head are arranged inside the table-type shell of the cooker, and the top of the burning head is slightly protruded from the table to form one, two or more burners; The core part of the device is set inside the countertop shell of the cooker, and the control switch of the ignition device, that is, the common ignition knob, is set on the cooker shell table, or on the side elevation of the shell close to the cooker; and the gas input The control device is generally integrated with the ignition device to make an integrated device of "ignition-gas input control"; the ignition knob acts as a gas input adjustment knob after the ignition action is completed, continuous or step The input volume of the gas can be adjusted in a formula to realize the control of the fire volume.

In modern society, energy conservation, environmental protection and people-oriented are the design concepts that any industrial product must follow. Such as gas stoves and other daily-use industrial products that almost every family must use, their energy saving, environmental protection and safety requirements are the fundamental driving force for the upgrading of gas stoves. To achieve these requirements, we must first start with its combustion system.

The basic structure of the combustion system of a traditional gas stove is to spray combustible gas onto the cast iron stove head and add a fire cover on the stove head. The bottom of the pot for food. This kind of combustion system structure has two defects. One is that when the gas burns on the flame distribution cover, it completely depends on the oxygen in the surrounding air, that is, the gas starts to burn without being fully mixed with oxygen in advance, which will cause the gas to not burn fully. , resulting in waste of energy and excessive emissions of harmful gases in the gas; second, the gas combustion here is a kind of flame combustion, and the utilization of heat generated by gas combustion depends on the natural contact distance between the pot and the flame, the heat exchange efficiency extremely low.

Chinese patent application number is the utility model patent application of 200720120452.9, discloses a kind of jet type gas cooker. One of its structural features is that the gas is mixed with air in a hollow cylinder before combustion, so that the final combustion gas is a mixed gas. Compared with the above-mentioned traditional gas stove, the gas utilization rate of this gas stove has been improved a lot, and the emission of harmful gas has also been reduced; Attached to the bottom of the pot for combustion, thereby reducing the heat transfer loss and improving the heat exchange efficiency. However, the pre-mixing of gas and air in this jet-type gas cooker is a natural mixing in a hollow cylinder space, the degree of mixing is not high, and the mixing effect is general, so that the gas cannot be fully mixed. In addition, whether it is bottled gas or piped gas, the ejection pressure is limited. This kind of jet gas stove is equipped with a flame control cover, relying on the ejection pressure of the gas to make the mixed gas burn on the flame control cover. The effect is also limited, and the improvement of heat exchange efficiency is not obvious.

The utility model patent application with the Chinese patent application number 200720170882.1 discloses a blower type gas stove. Since the blower input port is set on the stove head (ie, the combustion head), the blower and other blower devices can actively blow into the stove head. Injecting more air, on the one hand, increases the supply of oxygen, and makes the mixture of air and gas more fully; It is burned close to the bottom of the pot, and its heat energy utilization efficiency has been greatly improved. Completely fully combusted gas can reduce harmful gas emissions and save gas. However, this patent application only discloses the gas cooker with the above-mentioned blowing structure, and in this patent application, it is equivalent to only introducing the improvement scheme of the combustion head part in the gas cooker, without further providing how to make the blowing device and A technical solution for matching the gas input control device. In fact, when the air volume blown into the combustion head by the blower device is positively correlated with the gas volume input into the combustion head, the gas stove can achieve the best working condition.
