Abstract
The utility model discloses a lower part of steam cleaner boiler which comprises cast aluminium members and electric heating pipes. The inner side of the cast aluminium member has dents to form the bottom of a container, and the surrounding is equipped with sealing member containing structures. The lower part of steam cleaner boiler is characterized in that the electric heating pipes are cast inside the cast aluminium member with compression casting method; both end parts of the electric heating pipe stretch out from one side of the cast aluminium member; each end part is connected with an electric pole terminal. The utility model has high thermal efficiency, and the service life of the electric heating pipe is prolonged at the same time.
Description
Technical field
The utility model relates to a kind of parts of steam cleaner, is specifically related to be used in a kind of steam cleaner provide the lower body of the boiler of steam, and it is the part of water container, contains electric heater unit again.
Background technology
Steam cleaner is made of body, valve, nozzle, communicating pipe, boiler and the control structure be located in the body usually, and boiler wherein is used to add hot water and produces steam.Usually, the boiler in the steam cleaner adopts Electric heating, and boiler comprises boiler lower body, boiler body and lid, is provided with electric heating tube in the boiler lower body, and the boiler lower body is connected with boiler body with seal by securing member.Usually, the boiler lower body is made of aluminum casting and electric heating tube, and the aluminum casting bottom surface is provided with groove, and electric heating tube is embedded in the groove, fixedlys connected with aluminum casting by several pads.
There is the problem of two aspects in this structure, on the one hand, because the contact area of electric heating tube and aluminum casting has only about half of its surface area, and its contact is not too tight, causes thermal resistance bigger, so heat transfer efficiency is not high enough, and simultaneously, water in the boiler is to contact with the another side of aluminum casting, and caloric requirement just can be transmitted in the water through whole aluminum casting, thereby the efficiency of heating surface is not high; On the other hand, about 1 kilowatt, its lateral surface is exposed in the air power of electric heating tube usually, and it is in bad order to dispel the heat, and the temperature difference on electric heating tube two sides can influence the service life of electric heating tube, thereby influences the service life of steam cleaner.
Summary of the invention
The utility model purpose provides a kind of steam cleaner boiler lower body, by structural improvement, improves the thermal efficiency of boiler, prolongs the service life of electric heating tube.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steam cleaner boiler lower body, comprise aluminum casting and electric heating tube, the inboard depression of aluminum casting constitutes container bottom, be provided with the seal contained structure around it, described electric heating tube die casting is in the inside of aluminum casting, and stretch out from a side of aluminum casting 2 ends of electric heating tube, and each end is fixedly connected with an electrode terminal.
In the technique scheme, before making aluminum casting, earlier with the electric heating tube brake forming, electrode terminal is fixedlyed connected with the electric heating tube end, behind the mould holding electric heating tube, carries out die casting, thereby obtains aluminum casting.The required distance of electric heating tube each several part and aluminum casting medial surface is even, to guarantee the equilibrium of heating.
For reducing the diameter of electric heating tube, need its length of lengthening, thereby in onesize boiler lower body, electric heating tube need be done multiple bending, for further improving the uniformity of heating, usually can select following structure, that is, described aluminum casting is a disc, described electric heating tube is provided with 3 bendings in the face parallel with the aluminum casting bottom, the bending in the middle of it is positioned at the semicircle of nearly electrode leads to client.
In the technique scheme, described electric heating tube end cross-sectional is circular, and the upper and lower both sides of body portion are plane.
Further technical scheme is provided with Thermal Cutoffs fixed bit and temperature sensor fixed bit outside the described aluminum casting.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
Since the utility model with electric heating tube die casting in aluminum casting inside, heat conducting efficient improves, simultaneously, the distance between the water in from electric heating tube to boiler shortens, thereby has improved the thermal efficiency;
2. electric heating tube in aluminum casting inside, has been avoided the part body to be exposed at airborne problem by die casting, has prolonged the service life of electric heating tube;
3. aluminum casting adopts integrative-structure, and its inner recess surface directly contacts with water, compares with split-type structural, can avoid the heat conduction loss at the split connecting portion.
