[0028] Reference Figures 1-5A heat insulation structure for a clothes dryer heater includes an outer cover 1 and a heating and drying chamber 2 formed inside the outer cover 1. A waterproof and heat-insulating bag 3 is provided at the bottom of the outer cover 1. If the volume of the outer cover 1 is large, the number of bags 3 can be increased. The bags 3 can be rectangular, square, or circular, etc., as long as they fit the shape of the electric heater 5. A mounting cavity 4 is formed inside the bag 3 for mounting the electric heater 5. A heat dissipation hole 6 is provided on the top surface of the bag 3, through which the heat dissipation end 51 of the electric heater 5 extends into the outer cover 1. The bottom surface of the bag 3 is an air inlet mesh 7, and the bottom surface of the bag 3 is higher than the bottom surface of the outer cover 1 to facilitate the smooth intake of air into the electric heater. The air inlet 52 of the device 5 will not obstruct the intake of air even if the bottom of the electric heater 5 is not equipped with support feet; the front of the bag body 3 has an inlet 8 for inserting or removing the electric heater 5; the back of the bag body 3 has a cable hole 9 for the power cord 10 to pass through; elastic rings 11 are installed on the heat dissipation hole 6 and the cable hole 9, which can expand and automatically contract; the electric heater 5 includes an electric heating wire and a fan installed inside, as well as a heat dissipation end 51 installed at the top and an air inlet 52 located at the bottom; the heat dissipation end 51 is roughly a hollow cylinder with a hot air outlet on its side wall, and the air inlet 52 is a bottom plate with several air inlets on it.

[0029] In use, the electric heater 5 is inserted into the placement cavity 4 inside the bag body 3 through the inlet 8, and the heat dissipation end 51 extends from the heat dissipation hole 6 into the outer cover 1. When the electric heater 5 is working, air is drawn in from the air inlet 52 at the bottom under the action of the fan. After being heated by the electric heating wire, the air is discharged from the heat dissipation end 51 into the outer cover 1, and then the air and clothes in the outer cover 1 are dried. Elastic rings 11 are installed on the heat dissipation hole 6 and the wiring hole 9, which can expand and automatically contract. This allows the heat dissipation hole 6 and the heat dissipation end 51, as well as the wiring hole 9 and the power cord 10, to automatically adapt, making installation and disassembly convenient. At the same time, it minimizes the gap between the two to reduce the entry of hot air into the bag body 3. The bag body 3 is a relatively closed space, which reduces the damage of hot air in the outer cover 1 to electronic components and other parts during long-term drying of clothes. The bag body 3 is made of waterproof and heat-insulating material, which can reduce water droplets on the clothes from falling onto the electric heater 5 except for the heat dissipation end 51, reducing safety hazards. This structural design is economical and practical. It can be achieved simply by sewing a waterproof and heat-insulating bag 3 at the bottom of the original outer cover 1. It is simple and convenient, and will not increase the cost too much, but it can solve some of the shortcomings of the existing technology.

[0030] In some embodiments, one side of the outer cover 1 is equipped with a door 13 that can be opened and closed via a U-shaped zipper 12, making it convenient to take out and put in clothes; the top of the outer cover 1 is provided with multiple moisture discharge holes 14 arranged in parallel along the length direction, which facilitates the smooth discharge of moisture and improves the drying speed.

[0031] In some embodiments, a foldable support 15 is installed inside the outer cover 1, which expands both the outer cover 1 and the bag body 3 into a relatively flat state, maintaining sufficient storage space. The support 15 includes a horizontal frame 16 and two side frames 17. The two side frames 17 are hinged to the two sides of the horizontal frame 16 respectively. The included angle between the side frames 17 and the horizontal frame 16 is an obtuse angle, which can cooperate with a lock or buckle to improve the stability of the support 15. The two ends of the horizontal frame 16 abut against the upper sides of the outer cover 1, and the lower ends of the side frames 17 abut against the lower sides of the outer cover 1. The support 15 can be folded and unfolded, making it convenient to use and store.

[0032] In some embodiments, the bag body 3 is sewn to the bottom front end of the outer cover 1 to facilitate the installation or removal of the electric heater 5; the bag body 3 includes a waterproof outer layer 18 and a heat-insulating inner layer 19, which are sewn together. The waterproof outer layer 18 reduces the risk of liquid ingress, and the heat-insulating inner layer 19 reduces the entry of heat into the bag body 3.

[0033] In some embodiments, the waterproof outer layer 18 of the outer cover 1 and the bag body 3 is sewn from suitable materials such as Oxford cloth, polypropylene cloth or PEVA. PEVA, or polyethylene-vinyl acetate, is a blend of PE and EVA, and has good softness and elasticity. The heat-insulating inner layer 19 of the bag body 3 is made of suitable materials such as heat-insulating cotton, flame-retardant cotton cloth or aramid. By using the above materials, the bag body 3 has certain waterproof and heat-insulating properties.

[0034] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
