Abstract
The utility model discloses a steam generator which comprises a casing, a water injection circuit, an electric heating pipe and a temperature controller, wherein a water injection hole and an air outlet hole are formed in the casing, and an electromagnetic water pump injects water into the steam generator through the water injection hole. The water injection control circuit is connected with the electromagnetic water pump and used for controlling the electromagnetic water pump not to inject water into the steam generator within a scheduled time before cooking time is over. The temperature controller is arranged in the casing and close to the electric heating pipe and used for controlling on and off of a power supply circuit of the electric heating pipe according to the temperature of the electric heating pipe. By utilizing the additionally-arranged temperature controller to control the electric heating pipe circuit, protection effect is achieved, residual water is removed completely, the electric heating pipe is prevented from working without water for a long time, and therefore, the steam generator is safe and capable of saving energy and protecting the environment.
Description
Technical field
The utility model relates to a kind of steam generator.
Background technology
Traditional steam generator is in when work, and electrothermal tube heats always, and Electromagnetic water pump draws water by programme-control intermittence in steam injection generator, and venthole can intermittent constantly ejection steam, heat food.If the firm injected water of Electromagnetic water pump, and now cooking length of time stops, electrothermal tube quits work, and the water just having injected can be kept in steam generator always, for a long time no longer using appliance water quality degenerate, unhealthful.
Because Electromagnetic water pump is also intermittent water filling, if the moment of cooking length of time before last 2 minutes, just need Electromagnetic water pump water filling, and last 2 minutes of program setting can not water filling, electrothermal tube is understood the dry combustion method long period in such cases, can damage cast aluminium shell and cause peripheral temperature too high, bring harmful effect.
Utility model content
Main purpose of the present utility model is to overcome existing deficiency, and a kind of steam generator is provided.
For achieving the above object, the technical solution of the utility model provides a kind of steam generator, comprises housing, water injection control circuit, electrothermal tube and temperature controller; On described housing, be provided with water injection hole and venthole, Electromagnetic water pump by described water injection hole to steam generator water filling; Described water injection control circuit is connected with Electromagnetic water pump, within the scheduled time before cooking length of time finishes, controls described Electromagnetic water pump no longer to steam generator water filling; Described temperature controller is arranged on described enclosure interior and approaches electrothermal tube place, for control the break-make of electrothermal tube power supply circuits according to the temperature of electrothermal tube.
Further, described electrothermal tube is U-shaped, and the intermediate portion described enclosure interior that is placed in extends to the bottom of described enclosure interior always, and its two ends are positioned at described hull outside.
Further, the described scheduled time is 2 minutes.
Further, described venthole is one or more.
Compared with prior art, the utility model has the advantage of: by increasing temperature controller, thereby control electrothermal tube circuit, play a protective role, both guaranteed Ex-all residual water, can prevent again the long-time dry combustion method of electrothermal tube, safety, energy-saving and environmental protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of steam generator of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of steam generator of the present embodiment as shown in Figure 1, comprises housing 3, water injection control circuit, electrothermal tube 1 and temperature controller 4; On described housing 3, be provided with water injection hole 5 and venthole 2, Electromagnetic water pump by described water injection hole 5 to steam generator water filling; Described water injection control circuit is connected with Electromagnetic water pump, within the scheduled time before cooking length of time finishes, controls described Electromagnetic water pump no longer to steam generator water filling; Described temperature controller 4 is arranged on described housing 3 inside and approaches electrothermal tube 1 place, for control the break-make of electrothermal tube power supply circuits according to the temperature of electrothermal tube 1.
Described electrothermal tube 1 is U-shaped, and described housing 3 inside that are placed in, intermediate portion extend to the bottom of described housing 3 inside always, and its two ends are positioned at described housing 3 outsides.
The described scheduled time is 2 minutes.
Described venthole 2 is one or more.
Described water injection control circuit adopts the time relay.
The utility model is by increasing temperature controller, thereby control electrothermal tube circuit plays a protective role, and has both guaranteed Ex-all residual water, can prevent again the long-time dry combustion method of electrothermal tube, safety, energy-saving and environmental protection.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
