Abstract

A hand-held bed sheet warmer device is provided for heating bedding, including an air intake configured to intake air, a fan and heating coil assembly to receive and heat the air to provide warm air, a handle configured in between the air intake and the fan and heating coil assembly and having a hollow cavity formed therein to allow the air to pass through the handle from the air intake to the fan and heating coil assembly, and a warm air distributor rod configured to receive the warm air and comprising a plurality of outlet vents configured to distribute the warm air to the bedding. The air intake, the fan and heating coil assembly, the handle and the warm air distributor are arranged linearly and the device is configured as a hand-held baton or shaft.

Claims

1. An apparatus for heating bedding, comprising:

a fan and heating coil assembly to receive and heat air to provide warmed air, the fan and heating coil assembly comprising a fan and a heating coil;

a single air intake configured to intake the air that is received by the fan and heating coil and provided as warmed air;

a handle configured in between the air intake and the fan and heating coil assembly and comprising a hollow cavity formed therein to allow the air to pass through the handle from the air intake to the fan and heating coil assembly;

a warm air distributor rod configured to receive the warmed air and comprising a plurality of outlet vents configured to distribute the warmed air to the bedding;

wherein the air intake, the fan and heating coil assembly, the handle and the warm air distributor rod are arranged linearly and the apparatus is configured as a hand-held baton or shaft;

wherein the handle comprises a proximal end and a distal end,

wherein the proximal end adjacent to the fan and heating coil assembly;

wherein the air intake is arranged on the distal end of the handle,

wherein the handle comprises an elongated section formed between the proximal and distal ends and configured to be gripped by a user of the apparatus, and

a swivel connection connected between the warm air distributor rod and the fan and heating coil assembly, wherein the swivel configured to enable the warm air distributor rod to rotate freely during use of the apparatus.

2. The apparatus according to claim 1, further comprising a power switch arranged on the handle configured to control an electric power supply to the apparatus.

3. The apparatus according to claim 2, wherein the power switch is a spring-released on-off switch that is configured to power off the fan and heating coil when the handle is released by a user.

4. The apparatus according to claim 1, wherein the heating coil of the fan and heating coil assembly comprises a ceramic heating coil.

5. The apparatus according to claim 1, wherein the fan of the fan and heating coil assembly is a centrifugal fan.

6. The apparatus according to claim 1, further comprising an insulating layer formed around the heating coil and fan assembly.

7. The apparatus according to claim 1, wherein the fan and heating coil assembly comprises a thermal cutoff switch configured to cut off power to the fan and heating coil assembly if the fan and heating coil assembly reaches a predefined maximum temperature.

8. The apparatus according to claim 1, wherein the air intake comprises a protective screen and filter configured to filter the air entering the air intake.

9. The apparatus according to claim 1, wherein the plurality of outlet vents of the warm air distributor rod are arranged along the entire length of the warm air distributor rod.

10. The apparatus according to claim 1, wherein the warm air distributor rod further comprises a plurality of gliders configured to provide a space between a surface of the bedding and the plurality of outlet vents of the warm air distributor rod.

11. The apparatus according to claim 1, wherein the warm air distributor rod is configured to be attachable and detachable from the apparatus so that the warm air distributor rod can be stored separately from the apparatus.

12. The apparatus according to claim 1, wherein the warm air distributor rod is configured to have an adjustable length.

13. The apparatus according to claim 1, wherein each of the plurality of outlet vents comprises one or more deflectors to provide a spiral air flow for deep heating of bedding.

14. The apparatus according to claim 1, further comprising:

a spring release power switch arranged on the handle configured to control an electric power supply to the apparatus; and

a power cord having a first end attached to the handle and a second end comprising a plug for a wall outlet, wherein the power cord is configured to supply electric power to the apparatus from the wall outlet;

wherein the warm air distributor rod comprises the plurality of outlet vents along the length of the warm air distributor rod and a plurality of gliders configured to provide a space between a surface of the bedding and the plurality of outlet vents.

15. The apparatus according to claim 14, further comprising:

a ground fault interrupter;

an insulating layer formed around the fan and heating coil assembly;

a thermal cutoff switch configured to cut off power to the fan and heating coil assembly if the fan and heating coil assembly reaches a predefined maximum temperature; and

a protective screen and filter configured to filter the air entering the air intake.

16. The apparatus according to claim 1, wherein the warm air distributor rod further has a length of thirty inches.
