Abstract

The utility model relates to a steam cooking range. The heating device of the steam cooking range comprises a fuel jet burner, a heat change passage and a drawing wind flue. The outer part of a water container is provided with a water tank which is communicated with the water container, because the heat change passage is arranged in the inner part of the water container. The water tank is provided with a water intake non-return valve which is controlled through water level and a water outtake non-return valve which is controlled through water pressure difference, and the water container can keep the rated water level. So the thermal efficiency of the steam cooking range is high, and the steam cooking range can keep continuous steam supply state. In addition, after the steam cooking range selects a fuel jet atomizing burner which is driven through the electricity distribution to automatically ignite, the combustion of the steam cooking range is complete, and use is very convenient.

Description

Steam cooking range

The utility model relates to a kind of steam oven.

Steam oven comes down to a kind of steam generator that can directly do the kitchen range use.Form by heater, water container and kitchen range face.The heater of known steam oven is located at the outside of water container.Heat exchange is insufficient between the two.The thermal efficiency is very low; In addition, behind the discharge of steam, because of the water level in the water container descends.And water replenishes less than timely again, and therefore, this steam oven can not keep continuous steam supply state.

The purpose of this utility model provides a kind of energy and keeps continuous steam supply, and the high steam oven of the thermal efficiency.

Solve scheme of the present utility model and be and be provided with by fuel oil atomizer burner, hot switching path and the heater that draws the wind and smoke road to form.Wherein hot switching path is tortuous in water container, fuel oil atomizer burner and draw the wind and smoke road to lay respectively at the head of hot switching path and the outside that Wei ， And is installed in water container.Also be provided with the water tank that is communicated with water container in the outside of water container, this water tank is provided with the water inlet check valve that relies on water level control and relies on the water one-way valve that of differential water pressures control.

Further illustrate detailed content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: the utility model front view;

Fig. 2: the utility model vertical view;

Fig. 3: water tank water intake one-way valve structures sketch.

As shown in the figure: steam oven described in the utility model by water container 1, fuel oil atomizer burner 2, hot switching path 3, draw wind and smoke road 4, water tank 5 and kitchen range face 6 to form.Hot switching path 3 tortuous inside wherein at water container 1.Fuel oil atomizer burner 2 and draw wind and smoke road 4 to lay respectively at the head and the tail of hot switching path 3 again.And is installed in the outside of water container 1.Thereby the heater of forming water container 1; The water tank 5 that is located at water container 1 outside is communicated with water container 1, it is the water device for supplying of water container 1, this water tank 5 is provided with and relies on the water inlet check valve that the water level in the water tank controls and rely on the water one-way valve that goes out that differential water pressures between water container 1 and the water tank 5 controls, and the structural shape of the water inlet check valve of controlling by water level is more.Present embodiment employing ball-cock assembly rod-type, when water tank 5 water inlets, during ball float 7 come-ups, ball float 7 finally makes water inlet close by lever pushing valve rod 8 motion ， And, and when water level decline, when ball float is floated downward, intake pressure will be pushed the valve rod 8 of water inlet open and intake to water tank 5; Present embodiment will go out water one-way valve and be located at and connect on the pipeline of water tank 5 with water container 1, spool be a fan only can folk prescription to the valve plate 9 of rotation.Its effect also cuts off water in the water container 1 with the heat exchange of the water in the water tank 5 except the one-way flow of control water; It is in order to increase the area of heat exchange that hot switching path 3 is designed to tortuous shape, improves the thermal efficiency, and in order further to achieve the above object, present embodiment becomes rectangle with the Section Design of hot switching path 3 again; Fuel oil atomizer burner 2 optional distribution drive the fuel oil jet atomization burner of igniting automatically, to improve the automaticity of steam oven; Kitchen range face 6 be arranged on water container 1 above, which is provided with the steam nozzle 10 of water container 1; Water container 1 is the container of a sealing, and outer setting thermal insulation layer 11 shells 12 and the leg 13 of container in order to improve the serviceability of steam oven, can be provided with steam valve and hot water tap on water container 1.So that draw steam and hot water, the observation window 14 of linking up with hot switching path 3 also can be set, on shell 12 so that monitor the combustion case of burner for using.

The steam oven of said structure, because of hot switching path is tortuous in the inside of water container, having again can be to the water tank of water container automatic water-supply.Make water container remain at specified water level, therefore, this steam oven thermal efficiency height can successively provide steam.In addition, after the apolegamy electricity drove the fuel oil jet atomization burner of lighting a fire automatically, this steam oven burning was used very convenient again fully.

Claims (2)

1, a kind of steam oven with heater, water container and kitchen range face, it is characterized in that: heater is by fuel oil atomizer burner 2, hot switching path 3 and draw wind and smoke road 4 to form, wherein hot switching path 3 is tortuous in water container 1, fuel oil atomizer burner 2 and draw wind and smoke road 4 to lay respectively at the head of hot switching path 3 and the outside that tail And is installed in water container 1, also be provided with the water tank 5 that is communicated with water container 1 in the outside of water container 1, this water tank 5 is provided with the water inlet check valve that relies on water level control and relies on the water one-way valve that of differential water pressures control.

2, steam oven according to claim 1 is characterized in that: the section of hot switching path 3 is a rectangle.
