Air outlet shed of clothes dryer

Abstract

The invention discloses an air outlet shed of a clothes dryer, which comprises a support column connecting part (12), a machine casing fixing part (13) and a grill cover, wherein the grill cover is connected between the support column connecting part (12) and the machine casing fixing part (13). The air outlet shed is characterized in that the grill cover consists of an arc-shaped circular cover body (1) and a plurality of flow guide plates (3), wherein a plurality of air outlets (2) are arranged on the arc-shaped circular cover body (1) in a radial way; grilles (11) are formed between the adjacent air outlets (2); each flow guide plate (3) is formed by the extension of the inner side wall (14) of the circular cover body (1) to the inner center (O) corresponding to the position in which the grille (11) is positioned; and a gap is formed between the adjacent two flow guide plates (3), and an air outlet passage (21) which is communicated with the air outlet (2) is formed. Compared with the prior art, the flow guide plate can obviously enhance the integral firmness and improve the support capability of the circular cover body; and under the condition that the air outlet shed is made with a larger size, the size of the air outlet can easily reach the standard of the national safety standard, the production and processing are convenient, the requirement of large air volume is satisfied, and the air outlet shed is very suitable for the clothes dryer with large power or large volume.

Description

technical field [0001] The invention relates to the technical field of shed type clothes dryers, in particular to an air outlet shed for clothes dryers. Background technique [0002] The shed dryer is a household appliance that uses hot air to dry clothes. It is especially suitable in the rainy south and brings many conveniences to people's lives. Such as the prior patent of the applicant: the Chinese utility model patent "A Shed-type Clothes Dryer" with the patent number ZL200620018906.7 (the announcement number is CN2895492Y), which discloses such a clothes dryer. The clothes machine includes a bracket, a heating element main body arranged on the bracket, a lower supporting pipe fitting and an upper supporting pipe fitting connected with the lower supporting pipe fitting. In the nut of the shed, an outer cover is fixed on the supporting pipe fittings, and the arch type air outlet shed is provided with sheet-shaped deflectors evenly along the circumference of the air outle...

Problems solved by technology

Its disadvantages are as follows: firstly, metal has a large thermal conductivity and fast heat conduction, so that in the actual use process, the high-temperature hot air flow makes the surface of the fan shed and the metal pipes supported by the upper part very hot, and it is easy for people to touch it accidentally during operation. Burns, and when the clothes are touched for a long time, it is easy to cause damage to the clothes, which poses a safety hazard; secondly, the air outlet is a single-wall thin sheet structure, the surface strength is not large, and the distribution of surface holes will affect the outflow of airflow. On the contrary, The distribution of surface holes meets the air flow requirements, and the stressed front of the supported columns of the metal air outlet shed is prone to deformation and depression, which is also not conducive to the balance and stability of the supported columns connected to it

The sectional view of the abutment type air outlet shed in this patent, as figure 1 As shown, the arch-type air outlet shed includes the air outlet shed body 1', the deflectors 2' evenly distributed along the circumference, and the air outlet 3' between two adjacent deflectors 2', in order to increase the air outlet After the overall size of the windshield is enlarged in the same proportion, in order to meet the international electrical safety requirements, that is, the B-type experimental probe of IEC61032 can touch the safety regulations, the width W of the air outlet 3' cannot be too large, which requires an increase in the air outlet 3', that is, increase the number of sheet-shaped deflectors 2' on the circumference to reduce the width W of the air outlet 3' between two adjacent deflectors 2', so that the number of air outlets 3' increases , when the clothes hanging on the supporting column are heavy, the main body 1' of the air outlet shed is easily deformed or even broken

At the same time, increasing the number of deflectors 2' will make the parts of the deflectors 2' close to the center too dense and close together, which will increase the difficulty of injection molding of the air outlet shed; moreover, the parts inserted into the center of the air outlet The support column and the numerous deflectors 2' located around it form a closed solid structure, which is not conducive to ventilation, resulting in prolonged cooling time of the product in the mold during the injection molding process of the air outlet shed, and even serious shrinkage cavities, which affect the appearance of the product; in addition , after increasing the air outlet shed and increasing the number of deflectors 2', the angle α between adjacent deflectors 2' becomes smaller, so that the radial dimension L of the deflectors 2' will increase and increase After leaving the air shed, the vertical length of the deflector 2' at the air outlet is also lengthened, which increases the number of deflectors 2' occupying the inner space of the air shed, which is not conducive to forming a large grid space in the air shed , and make the air outlet become slender
