Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-9, a drying machine with easily assemble heating element, includes a casing 1 of the drying machine, an electric control element 2, a motor 3 and a wind wheel 4 which are arranged in the casing 1 of the drying machine, an air inlet 5 and an air outlet 6 are provided on the casing 1 of the drying machine, an installation support 7 is provided at the air outlet 6, a heating block 8 is provided on the installation support 7, and the heating block 8 is electrically connected with the electric control element 2. The heating block 8 is a PTC ceramic heating block 8, on one hand, because the ceramic is heat-generating and non-conductive, and the surface is safe and uncharged, the insulating property is good, the use is safer, and the oxidation is not easy; on the other hand, the PTC ceramic heating block 8 can be made into a large whole block, the heating power is higher under the same volume, the mounting structure is unified and standard, and the operation is simpler and more standard.

Preferably, the PTC ceramic heating block 8 is a PTC automatic heater (insulating corrugated heating element).

More specific mounting methods of the heating block 8 are as follows: the heating block 8 is characterized in that a plurality of positioning inserting strips 9 are arranged on two sides of the heating block in an outward protruding mode, guide grooves 10 are formed in the mounting support 7, and the positioning inserting strips 9 are inserted into the mounting guide grooves 10. Through the cooperation of location cutting 9 and installation guide slot 10 for heating block 8 can be more direct, quick be connected with blowing machine casing 1, and form certain location connection effect.

Furthermore, the upper side and the lower side of the installation guide groove 10 are bent to form an elastic pressing piece 11 in the middle, and an insertion gap 12 for the positioning insertion strip 9 to pass through is formed between the elastic pressing pieces 11 on the upper side and the lower side. For smooth insertion, the elastic pressing piece 11 has an arc-shaped guide surface gradually contracting from the outside to the inside and forms a trumpet-shaped insertion gap 12, and the innermost ends of the upper and lower elastic pressing pieces 11 abut against each other. The rear end of the mounting bracket 7 is provided with a rear limiting baffle 13, an accommodating space 14 is formed between the rear limiting baffle 13 and the elastic pressing sheet 11, the positioning inserting strip 9 enters the accommodating space 14 after being inserted into the gap 12, and the positioning inserting strip 9 and the elastic pressing sheet 11 are abutted to form limiting and anti-falling fit. During production and installation, a worker or a machine takes the heating block 8, the positioning insert 9 is aligned to the insertion gap 12, and the horn-shaped insertion gap 12 is adopted, so that the positioning insert 9 can directly and smoothly enter the insertion gap 12, and the positioning insert 9 presses the elastic pressing piece 11 to deform the elastic pressing piece so as to avoid the insertion gap 12 with large enough size to pass through; when the positioning insert 9 is completely inserted into the accommodating space 14 through the insertion gap 12, the elastic pressing piece 11 is restored to the initial state through the elastic force of the elastic pressing piece 11, namely, the innermost end of the elastic pressing piece 11 is closed and abutted together, so that the elastic pressing piece can be abutted against the positioning insert 9 to form a limiting anti-falling fit, the positioning insert 9 is stably and reliably positioned in the accommodating space 14, and the heating block 8 is installed.

In order to determine the installation direction during installation and prevent rework caused by assembly errors, in this embodiment, the mounting bracket 7 is provided with a circuit interface 15, the front end of the mounting bracket 7 is provided with a fool-proof groove 16, and the fool-proof groove 16 and the circuit interface 15 are disposed on the same side. During operation, the worker can observe the fool-proof groove 16 intuitively, so that the direction angle of the heating block 8 relative to the floor blower shell 1 is adjusted according to the fool-proof groove 16, and quick and accurate installation is realized.

Because the shell of the blow dryer is mostly formed by plastic materials, although the modified plastic materials also have certain flame retardant property, when the high-power heating block 8 is selected, certain high-temperature denaturation and even burning risks may exist. The lower end of the mounting bracket 7 is also provided with a temperature controller 17, and the temperature controller 17 is electrically connected with the electric control component 2. On one hand, the temperature controller 17 can play a role in detecting the temperature inside the blow-drying machine in real time, and can feed back the temperature to the electric control component 2 to power off the heating block 8 when the temperature is too high, so that the work of the heating block is stopped, and the mounting precaution effect is played; on the other hand sets up the lower extreme at installing support 7, has solved the installation problem, is closer to heating block 8 simultaneously for temperature controller 17's temperature measurement is more accurate.

In this embodiment, the outer end of the mounting bracket 7 is bent to the periphery to form a front limit baffle 18, a circle of flanges 19 is convexly arranged on the inner wall of the air outlet 6, and the front limit baffle 18 is abutted against the flanges 19 to form limit fit. After the installing support 7 is placed into the floor blowing machine shell 1, the installing support 7 can be prevented from falling off in a limiting mode through the matching of the limiting baffle and the flange 19, and the pre-installing effect is achieved. Further, the air outlet 6 is provided with a protective cover 20, the flange 19 and the front limit baffle 18 are all provided with threaded connecting holes 21, so that the protective cover 20, the flange 19 and the front limit baffle 18 are fixedly connected together through screws.

According to the utility model, the heating block can be closed and used as a cold air blow dryer; the heating block can also be started to be used as a hot air dryer.

The utility model provides a blow dryer with an easily assembled heating assembly, which adopts a blocky PTC ceramic heating block 8 to replace the existing multi-tubular infrared electric heating pipe, on one hand, the ceramic heating is non-conductive, the surface is safe and uncharged, so the insulation performance is good, the blow dryer is safer to use and is not easy to oxidize; on the other hand, the PTC ceramic heating block 8 can be made into a large whole block, the heating power is higher under the same volume, the mounting structure is unified and standard, and the operation is simpler and more standard.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
