Description

Technical field

[0001] The invention relates to a household air heater for heating, in particular to a pressurized and accelerated air heater core component capable of increasing the wind pressure and wind speed at an air outlet. [Background Technology]

[0002] A household fan heater is a small, portable heating device that heats incoming cold air through an electric heating element and delivers it indoors. It is popular for its small size, portability, and ease of control. Traditional household fan heaters use a fan to blow heated air directly into the room. Because the fan's impeller produces rotating air and lacks a deflector, it suffers from significant pressure loss. This inability to effectively converge the airflow results in a short air delivery distance, limiting the hot air's diffusion range and preventing it from quickly distributing the air to spaces slightly further away. These limitations result in low air circulation efficiency in traditional fan heaters. Furthermore, the components of traditional household fan heaters are often connected using screws, resulting in inefficient assembly and disassembly. Therefore, it is imperative to provide an outlet with high air pressure and velocity to quickly disperse hot air into the room, effectively improving air circulation efficiency. [Summary of the invention]

[0003] The present invention aims to solve the above problems and provide a heater core component that can increase the pressure and speed of the air outlet so that the hot air can be quickly diffused into the indoor space, thereby effectively improving the air circulation efficiency.

[0004] To achieve the above-mentioned object, the present invention provides a heater core assembly capable of increasing pressure and speed, the heater core assembly comprising:

[0005] A fan assembly, comprising a fan and a first outer frame accommodating the fan;

[0006] A booster deflector, which is connected to the air outlet side of the first outer frame of the fan assembly and increases the wind pressure and wind speed at the air outlet by converting dynamic pressure and static pressure;

[0007] A heating element assembly, comprising a PTC heating element and a heating element bracket for accommodating the PTC heating element, wherein the heating element assembly is connected to the air outlet side of the boost deflector;

[0008] The fan assembly is connected to the pressurized air deflector and the heating element assembly as a whole through screws or buckles. The pressurized air deflector can increase the wind pressure and wind speed at the air outlet to speed up air circulation.

[0009] The fan is an axial flow fan.

[0010] The first outer frame of the fan assembly is rectangular, and has a first inner ring on its inner side that is adapted to the wind wheel of the fan. First screw hole columns are respectively provided at the four corners of the first outer frame, and a number of protruding triangular snap-in blocks can be arranged at intervals on the outer circumference of the first inner ring.

[0011] The boost guide cover includes a second outer frame and a cover body arranged in the second outer frame. The second outer frame corresponds to the shape of the first outer frame of the fan assembly. The cover body is an annular body corresponding to the shape of the first inner ring of the fan assembly. A plurality of guide blades are provided on its inner wall. The guide blades are arc-shaped blades bent to the same side and are arranged at intervals along the inner wall of the cover body. Second screw hole columns corresponding to the positions of the first screw hole columns of the first outer frame are respectively provided at the four corners in the second outer frame. A first U-shaped clip protruding axially or an ear seat with a screw hole protruding radially outward is provided at the four corners on the outside of the second outer frame. A number of card slots corresponding to the positions of the triangular card blocks on the first inner ring of the fan assembly can be provided on the outside of the cover body.

[0012] The heating element bracket of the heating element assembly is a rectangular frame, with limiting protrusions provided at the inner corners, and several notches for the electrical connection terminals of the PTC heating element to extend out on one of the horizontal sides. The outer side of the heating element bracket is provided with block-shaped protrusions or third screw hole columns corresponding to the first U-shaped clip positions of the second outer frame of the boost deflector cover at the four corners.

[0013] The fan assembly, the boost deflector cover and the heating element assembly are connected by screws via a first screw hole column, a second screw hole column and a third screw hole column.

[0014] The fan assembly is connected to the pressurized air deflector by screws via the first screw hole column and the second screw hole column, and the pressurized air deflector is connected to the heating element assembly via its first U-shaped buckle and the block-shaped protrusion of the heating element assembly.

[0015] The fan assembly is clamped to several slots of the boost shroud through several triangular clamping blocks on its first inner ring, and the boost shroud is clamped to the block-shaped protrusions on the heating element bracket of the heating element assembly through the first U-shaped clamp on its second outer frame.

[0016] A guide vane reinforcement body is provided in the center of the cover body of the supercharged air guide cover. The guide vane reinforcement body is annular, and both ends of the guide vane are respectively fixed to the guide vane reinforcement body and the cover body.

[0017] The present invention contributes by effectively resolving the problems of existing household fan heaters, such as short air delivery distance and low air circulation efficiency. Due to the provision of a pressurized air deflector, the guide vanes within the deflector guide the rotating air blown by the impeller, converting the rotating dynamic pressure into vertical static pressure. This effectively increases the air pressure and velocity at the air outlet, allowing the warm air blown through the air outlet to quickly diffuse into the indoor space. This significantly improves the air circulation efficiency of the fan heater and reduces its energy consumption. Furthermore, the various components of the fan heater's core assembly can be flexibly assembled through methods such as snap-fitting, facilitating assembly, disassembly, and maintenance.
