Description

Energy-saving kitchen range

Technical field

The utility model relates to a kind of energy-saving kitchen range, belongs to the firing equipment technology.

Background technology

The energy-saving kitchen range that the utility model is related mainly is heating such as the poach that is used for the heated liquid medium, fried, the material of stewing soup, following and hinge and steam stuffed bun, the energy-saving kitchen range of catering trade such as steamed bun.

The existing kitchen range that are used for catering trade are made up of bowl and the combustion gas/kitchen or the coal furnace that are located under the bowl.Its thermal efficiency is very low undoubtedly.According to test, its utilization rate of heat value is greatly between 30%～40%.This shows that a large amount of combustion gas/oil or coal have not only been wasted in the energy resource consumption that existing kitchen range are so high, and increased considerably the cost of catering trade, directly strengthened financial burden for the consumer.This is the ubiquitous common problem of present catering trade.

Summary of the invention

The purpose of this utility model is to provide the energy-saving kitchen range of a kind of energy savings, pressure drop Cost of Catering Trade, to overcome the deficiency of prior art.

The utility model realizes that the technical scheme of its purpose is, a kind of energy-saving kitchen range, have the kitchen range frame, be fixed on the intensive Firetube heat exchanger that is vertically arranged bowl, combustion chamber on the kitchen range frame and is made of some fire tubes, its improvement is: said heat exchanger is located at the inner chamber of bowl; The perforation that is connected with the flue gas collection chamber of one end of the fire tube of heat exchanger, the other end of fire tube connects mutually with bowl and communicates with the combustion chamber; The perforation that is connected with smoke exhaust pipe of flue gas collection chamber, smoke exhaust pipe and bowl connect and draw the outside of bowl mutually.

Can understand by above given technical scheme, the utility model since the inner chamber that intensive heat exchanger is located at bowl and heated medium for example water/oil directly contact, and obviously improved heat exchanger effectiveness, thereby realized the purpose of the utility model energy saving and cost lowering.The lab scale test result shows that utilization rate of heat value of the present utility model can reach 70%～80%, has improved more than 2 times than the utilization rate of heat value 30%～40% of prior art.

The further improvement of the utility model point is:

Said bowl, combustion chamber and heat exchanger at least respectively have 2 and three to complement one another; Heat exchanger is arranged along the vertical center line of bowl; It is arranged apart that at least 2 bowls are a straight line, or symmetry is arranged apart or be symmetrical arranged apart all around before and after being; The perforation that is connected with total smoke exhaust pipe of per 1 blast pipe that is connected with the flue gas collection chamber.This further improved technical scheme has realized the intensive layout of a plurality of said kitchen range, can reduce its shared place, also helps making things convenient for the kitchen operation.

Between adjacent 2 bowls, be provided with hot water storgae.Can make full use of conduction, the radiant heat energy of bowl like this, in order to the water that is stored in the said tank is heated.And can replenish in the bowl through having heated water; Also can be used for adding hot tableware, make the dish or the staple food that leave in the warmed-up tableware can very fast cooling.

Said bowl is cylindric or is the quadrangle column; Bowl by upper pan body and cross-sectional area less than the cross-sectional area of upper pan body the lower pot body greater than the cross-sectional area of heat exchanger form.Why will be made into up big and down small cylindric/quadrangle column to bowl, be water or the oil that is present in the bowl in order to make, and formation is rolled up and down better, and help the processing of food, for example endures bone soup or the like.

Be provided with the heat-insulating material layer in the outside of bowl.Since for example existence of packing layer such as asbestos putty, fire clay of heat-insulating material layer, the further consumption of energy savings.

Be provided with water inlet and discharge outlet with water valve in the bottom of bowl.Owing to have the water inlet of water valve and the existence of discharge outlet, can further facilitate the replacing of water in the bowl/oil and to the cleaning of bowl.

Said combustion chamber is can ccontaining gas-cooker or the combustion chamber of oil range, or has the coal-fired chamber of fire grate.That is to say that the utility model can be suitable for combustion gas/kitchen or coal fired stove, make things convenient for the user to select mode of heating like this, thereby enlarged the scope of application of the present utility model according to physical condition.

After technique scheme was implemented, the utility model efficiently solved the higher practical problem of prior art energy consumption.The energy savings that it had, the pressure drop Cost of Catering Trade, characteristics and effect such as site environment is good are conspicuous.
