Abstract
The utility model discloses an electric water heater, composed of an inner bladder, an insulation layer and a casing. The inner bladder is inserted with devices, such as an electric heating pipe, etc.; the casing is composed of an upper and a lower casing bodies; the upper casing body is composed of a front cover casing and a front cover plate; the front cover casing is provided with a concave cavity provided with holes through which the inserting openings of the devices, such as the electric heating pipe, etc. on the inner bladder are exposed; the front cover plate is closely buckled on the concave cavity of the front cover casing; in addition, the upper and the lower casing bodies form involution assemblage in the mode of demountable connection. The electric water heater has simple structure, and components and parts can be conveniently dismounted; good heat-insulation property is kept, and the external shape can be easily tidied and beautified.
Description
The utility model relates to a kind of electric heater, belongs to household electrical appliance technical field.
Therefore remarkable advantages such as that electric heater has is safe in utilization, control simple, energy resource supply is convenient are just entering increasing family as modernized household electrical appliance.Existing electric heater is made of inner bag, heat-insulation layer and shell usually.Be fitted with devices such as electrothermal tube on the inner bag, shell is divided into upper and lower casing.During assembling, inner bag is placed in the middle, and it is whole that upper and lower casing fastens the back bonding, and filled with foaming material forms the integral heat insulation layer between inner bag and the shell.Though this class electric heater heat-insulating property is good, the long-term greatest problem that exists of using is: the consumable accessory on the inner bag in the electrothermal device of plug-in mounting is changed difficulty.In addition, when inner bag damages owing to reasons such as corrosion,, thereby can only scrap by complete machine, cause waste because can't dismantle.
Main purpose of the present utility model is: at the problem that above-mentioned existing electric heater exists, provide a kind of under the prerequisite that does not influence heat-insulating property, can very convenient dismounting inner bag in the electric heater of consumable accessory.
Another purpose of the present utility model is: the consumable accessory in inner bag was changed conveniently, the inner container of electric water heater that the utility model provides is dismounting and change easily.
Technical solution of the present utility model is: electric heater, constitute by inner bag, heat-insulation layer and shell, be fitted with devices such as electrothermal tube on the described inner bag, shell is divided into upper and lower casing, described upper shell is made of front cover shell and shroud upper panel two parts, described front cover shell has a cavity, and described cavity has and makes that device plug-in mounting mouth such as electrothermal tube exposes hole on the inner bag, and the shape of described shroud upper panel can airtightly be fastened on the cavity of described front cover shell it.In addition, adopt the involutory assembling of releasable connection mode between the described upper and lower shell.
Owing to device plug-in mounting mouths such as electrothermal tube on the utility model inner container of electric water heater all expose from the cavity of front cover shell, as long as just therefore open these devices of shroud upper panel dismounting easily.Simultaneously still use heat-insulation layer heat insulation between inner bag and the shell, in addition on the airtight cavity that is fastened on front cover shell of shroud upper panel, so heat-insulating property is unaffected.In addition, releasable connection between the upper and lower casing, the dismounting and change of inner bag has also obtained satisfactory solution.
Advantage of the present utility model is: simple in structure, the dismounting of parts is very convenient, has not only kept good heat-insulating property, and profile also is easy to accomplish carefully and neatly attractive in appearance.
Below in conjunction with accompanying drawing technical solution of the present utility model is described further.
Fig. 1 is the assembling schematic diagram of an embodiment of the utility model.
Electric heater among Fig. 1 is mainly by upper shell 2, lower house 6, heat-insulation layer 5, and the inner bag that is wrapped in the heat-insulation layer is formed.During assembling, upper shell 2 is connected by screw 14 with lower house 6.Upper shell 2 is divided into front cover shell 4 and shroud upper panel 8 two parts.Have the hole 13 and 11 that the inner bag plug-in mounting mouth that makes electrothermal tube 1 and magnesium pipe 12 exposes in the cavity 3 of front cover shell 4.The cavity 3 of the shape of shroud upper panel 8 and front cover shell 4 matches, one end of shroud upper panel 8 is provided with barb-like plug tenon 7, this plug tenon 7 matches with socket 10 on the front cover shell 4, helps to guarantee to make on the airtight cavity 3 that is fastened on front cover shell 4 of shroud upper panel 8, and can realize quick loading and unloading.Also be provided with automatically controlled plate 9 on the shroud upper panel 8.The automatically controlled part of this electric heater can judge whether " dry combustion method " by temperature rate-of-rise, and can cut off the power supply rapidly when temperature sensor is malfunctioning, breaks down to be shown by liquid crystal Chinese, in addition can also read clock, timing start-up and shutdown.
Experiment shows that the electric heater heat-insulating property of present embodiment is good, quick heating, and dismounting is convenient, and is easy to use, and good looking appearance.
