CN2250706Y - Household energy-saving gas cooking pot - Google Patents

Abstract

The utility model discloses a household energy-saving gas cooking pot, which is composed of covers, handles, a main body, and outer liners, wherein, inner circles on the central bottom part of the main body are a flat bottom part dented inwards; outer edges of the inner circles on the central part are provided with concave convex grooves; the lower half part of side walls of the main body is provided with concave ribs which are communicated with the concave convex grooves; the outer liners are tightly attached to the main body; the middle lower parts of the outer liners are provided with a circular hole. The bottom part of the main body is directly heated by flame which penetrates through the circular hole, then the flame arrives at the concave convex grooves through gap, and gas with high temperature is discharged out along the concave ribs. Cold air is prevented from flowing into the utility model having the advantages of increased air temperature and contacting areas, fully absorbed burning heat quantity by the main body, reduced burning time, and obvious energy saving effects. Through the utility model being tested, energy can be saved more than 25 %, and the heat efficiency of the utility model is above 70 %.

Description

The domestic gas energy-saving cooker

The utility model relates to the cooker articles for use, especially relates to a kind of domestic gas energy-saving cooker.

The heat exchange effect of the kitchen cooker of family's use at present is unsatisfactory, and the thermal efficiency is low, and the heat that has combustion gas greatly to produce is not absorbed by cooker and wasted.Notification number is that the Chinese patent " energy-conservation pot " of CN2123949U is designed to flat indent to intracardiac circle in the bottom of a pan, in the outer of intracardiac circle be distributed with convex helicla flute and evagination helicla flute, increased the heating surface area in the bottom of a pan, improved conductivity of heat, flame can form eddy current along helicla flute and shed naturally, played energy-conservation effect, but its energy-saving effect is unsatisfactory, the heat of the flame that gives out from helicla flute fails to be fully used.

The purpose of this utility model is to provide a kind of heat, Remarkable Energy Saving domestic gas energy-saving cooker that can make full use of burning.

The purpose of this utility model is achieved in that the utility model is made up of lid, handle, body and overcoat, intracardiac circle is flat indent in the feature body bottom, in the outer of intracardiac circle be processed with tongue and groove, the sidewall Lower Half of body is processed with the concave bar that communicates with tongue and groove, has a circular hole in the middle of the bottom of overcoat.

Concave bar has 6～20, and overcoat is close to body, makes overcoat and tongue and groove, concave bar form the gap, becomes passage of flame.

The utility model is owing to be processed with tongue and groove and concave bar, not only increased heating surface area, and the what is more important overcoat is close to body, flame is flowed out along passage, completely cut off the intrusion of cold air, improved temperature, body is fully absorbed and utilize the burning heat, shortened the time of burning, energy-saving effect is remarkable.Through test, but energy savings is more than 25% under the same conditions, and the thermal efficiency is more than 70%.

Fig. 1 is the structure cross-sectional schematic of pot.

Fig. 2 is the structure cross-sectional schematic of kettle.

Fig. 3 is that the A-A of Fig. 1, Fig. 2 is to top cross-sectional view.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The utility model is made up of lid 1, handle 2, body 3 and overcoat 4, intracardiac circle 5 is flat indent in body 3 bottoms, in the outer of intracardiac circle 5 be processed with tongue and groove 7, the sidewall Lower Half of body 3 is processed with the concave bar 9 that communicates with tongue and groove 7, concave bar 9 has 6～20, and overcoat 4 is close to body 3, has a circular hole 6 in the middle of its bottom, form gap 8 between overcoat 4 and tongue and groove 7, the concave bar 9, become passage of flame.

Kettle also is processed with kettle mouth 10.

After the utility model is loaded onto object, be placed on the stove and accessory, flame passes circular hole 6, directly heater body 3 bottoms in intracardiac circle 5,8 be burned to tongue and groove 7 through the gap again, high-temperature gas is discharged along concave bar 9, the heat that burning is produced can fully be absorbed.Because of overcoat 4 and body 3 closely combine, the heat that overcoat 4 is absorbed also can be passed to body 3 effectively, further absorbs the loss that heat has reduced energy.

Claims (3)

1, a kind of domestic gas energy-saving cooker, form by lid (1), handle (2), body (3) and overcoat (4), it is characterized in that: intracardiac circle (5) is flat indent in body (3) bottom, in the outer of intracardiac circle (5) be processed with tongue and groove (7), the sidewall Lower Half of body (3) is processed with the concave bar (9) that communicates with tongue and groove (7), has a circular hole (6) in the middle of the bottom of overcoat (4).
