Abstract

The utility model relates to an efficient energy-saving ring for a gas stove. Three groups of functional sheets are arranged at the bottom of a ring body. A conduction strip 2 is connected with a fire block sheet 4. A distance between a radiation fin 3 and the fire block sheet 4 is 1.5 centimeters. The radiation fin 3 and the fire block sheet 4 are mutually interlaced. An energy saving principle is that radiation and heat conduction are generated through absorbing the afterheat of the outer layer of a pan bottom. The rotation time of high temperature at the pan bottom is extended. The utility model has the advantages of air prevention and shield and avoidance of convection between heat power and cold air.

Description

The gas furnace high-efficient energy-saving ring

The utility model is that a kind of liquefied gas furnace (or biogas stove) that is installed in is gone up matching used energy saving ring.This energy saving ring is tested repeatedly through 39 design moldings and is developed name " gas furnace high-efficient energy-saving ring ".

The matching used energy-conserving device of known domestic gas furnace is similar in design, structure, purposes etc., each tool advantage, but total be the thermal efficiency not high (generally about 65%), the calorific value loss is excessive, for China of energy shortage, shortage, the energy-conservation of this respect had great potentialities.

So the purpose of this utility model is to do one's utmost to reduce heat loss, obtain higher thermal efficient, reach the solar term that save time, thereby " gas furnace high-efficient energy-saving ring " is provided.This energy saving ring is formed iron casting by seven parts such as a pot support 1, conducting strip 2, radiation fin 3, fire blocking piece 4, circle body 5, screw rod support 6, circle pin rings 7 altogether.It is characterized in that being provided with three groups " functional sheets " in the circle body bottom: conducting strip 2 links to each other with fire blocking piece 4, radiation fin 3 and apart 1.5 centimetres of fire blocking pieces 4, and interlaced.Its energy-saving principle is: 1. absorb the outer waste heat in the bottom of a pan and produce radiation, heat conduction, obtain the calorific value conversion using; 2. prolong calorific value (high temperature) and circle round the time, make full use of calorific value in the bottom of a pan; 3. windproof keeping out the wind avoided combustion heat value and cold air convection, reduces the calorific value loss.Thereby the thermal efficiency is reached more than 75%, and fractional energy savings reaches 30.5% to 34%.Be better than known energy-conserving device greatly.This energy saving ring is applicable to cookers such as the aluminum pot, frying pan of the gas furnace of various different brands, model and various different size, model, and wide adaptability is promoted easily.

Below in conjunction with drawings and Examples, the utility model is further described:

Fig. 1 is a schematic diagram of the present utility model,

Fig. 2 is the vertical view of Fig. 1,

Fig. 1,21, a pot support, 2 conducting strips, 3, radiation fin, 4, fire blocking piece, 5, circle body, 6, the screw rod support, 7, circle pin ring.

Embodiment is as shown in Figure 1, 2: when this energy saving ring is installed, earlier original pot supporter on the stove is taken down, this energy saving ring is aimed at the center frame be placed on the gas furnace liquid-bearing pan, again frying pan (sunken bottom pot) frame is placed on the energy saving ring, check " hanging fire " highly (being the bottom of a pan and firn-jet head distance).Method of adjustment mainly is to turn round long with three " the screw rod supports 6 " that install energy saving ring bottom or shorten, and " hanging fire " remained on about 1 centimetre, then will " screw rod support 6 " up and down two nuts tighten and block, install promptly to accuse and finish.

This energy saving ring passes through Test Identification, the thermal efficiency reaches 75.4%, by the test comparison of heating up water, under the identical situation of test condition (water initial temperature, per minute air consumption etc.), this energy saving ring is installed than " overall average programming rate " (℃/minute) do not installed fast 30.5% to 34% (being energy-conservation 30.5 to 34%), every technical indicator all meets or exceeds " 96 years Chinese patent and new product fair " prize-winning similar energy-conservation tool advanced level, have modern design, fractional energy savings height, characteristics such as simple and easy, easy to use are installed, the real energy-conservation best auxiliary products of gas furnace that belong to.

Claims

The gas furnace high-efficient energy-saving ring by circle body 5, comprises seven parts compositions such as propping up pot support 1, screw rod support 6, circle pin ring 7, iron casting is characterized in that, is provided with three groups of functional sheets in circle body 5 bottoms, conducting strip 2 links to each other with fire blocking piece 4, radiation fin 3 and apart 1.5 centimetres of fire blocking pieces 4, and interlaced.
