Abstract
The utility model relates to a temperature control device of an electric auxiliary heater of a PTC air conditioner, which comprises a temperature controller and a temperature fuse, wherein the temperature controller and the temperature fuse are mutually connected in series and are installed inside the same plastic shell (1), and a cover plate is covered on the plastic shell (1) in a detachable type. The utility model is characterized in that the plastic shell (1) is connected with a bracket (4), and the bracket (4) and the plastic shell (1) are formed into an integral structure by injection molding at one time. The utility model has the advantages that the bracket and the plastic shell are formed into the integral structure by injection molding at one time, and the process step of assembling the plastic shell and the plastic bracket mutually can be left out, so that unnecessary man-hours of manufacture can be reduced efficiently; in addition, the bracket and the plastic shell are formed by injection molding, and the utility model also has the advantages of firm mutual structures, regular and beautiful appearance, material saving, and time saving, so that both the temperature controller and the temperature fuse can be ensured to work in an environment with accurate temperature control, stable performance and high safety.
Description
Technical field
The utility model relates to a kind of parts of air conditioner, especially refers to a kind of temperature control equipment of the PTC of being used for air-conditioning electric heating device.
Background technology
At present, the temperature of common PTC (pottery) air-conditioning electric heating device control on the market, mainly be to realize by temperature controller and temperature fuse that series connection is installed on electric heater, present mounting means has two kinds, a kind of is the different parts that temperature controller and temperature fuse are installed in well heater respectively, and another kind is that temperature controller and temperature fuse are installed on the fixed support of well heater; Because in these two kinds of mounting meanss, temperature controller and temperature fuse are to install separately respectively, not only layout is unreasonable, assembling inconvenience, but also can cause temperature controlled inconsistency and temperature control inaccurate, thereby causes defectives such as its reliability and poor stability.The patent No. is that 03270341.4 Chinese utility model patent has proposed a kind of structure for this reason, its structure is temperature controller and the temperature fuse that comprises mutual series connection, it is characterized in that described temperature controller and temperature fuse are installed in the same plastic casing, and both bottom surfaces are close to mutually with the plastic casing inner chamber.This structure makes temperature controller and temperature fuse can experience same environment temperature, temperature controlled consistance and stability have been improved, but its shortcoming is, because of plastic casing and plastic stent are to be made separately, so will be fixed on the support plastic casing that temperature controller and temperature fuse are installed in it pretty troublesome, take a lot of work during both assembly fees, and manufacturing materials is many respectively, cost is high for plastic casing and support, and make trouble, production efficiency is low, so its structure awaits to improve.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple in structure, easy to assembly, cost of manufacture is low and temperature control is more accurate and performance is more stable temperature control equipment that is used for PTC air-conditioning electric heating device is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the temperature control equipment of PTC air-conditioning electric heating device, include temperature controller and temperature fuse, described temperature controller and temperature fuse are connected mutually and are installed in the same plastic casing, and detached type is stamped cover plate on plastic casing, it is characterized in that described plastic casing and support link together, and support and plastic casing are disposable injection molded one-piece construction.
As improvement, described support also can be provided with the ear shape protuberance that can be used for fixing on its side, and this ear shape protuberance has screw in it, and also can be embedded with metallic sheath in this screw, is shaped on the screw thread that can fix with screw on the inwall of this metallic sheath.
As further improvement, described detached type structure may be selected to be at the plastic casing afterbody and is provided with protruding button, this protruding button is provided with opening jack forward in it, and be provided with plug at cover plate afterbody and the protruding relevant position of buckleing, its afterbody of described cover plate is inserted in the protruding jack of buckleing by plug, and the cover plate front portion has screw hole to be fixed together by screw and plastic casing front portion.
Compared with prior art, advantage of the present utility model is to be fixed on the support because of described plastic casing, and support and plastic casing are disposable injection molded one-piece construction, not only possessed temperature controller and temperature fuse and can experience same environment temperature, and both are kept consistency and stability, and plastic casing and plastic stent are the one-piece construction that disposable injection molding material forms, thereby removed the operation that plastic casing and plastic stent assemble mutually from, so just reduced unnecessary making man-hour effectively; It is disposable injection molded also having plastic casing and support, mutually also more firm, the outward appearance of structure more neat, attractive in appearance, and material-saving saves time, thereby guaranteed temperature controller and temperature fuse can be more accurate at temperature control, performance is more stable, work in the better environment of security, so the utility model is a kind of product very ingenious, is worthy of popularization.
