Description

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention is related to a cup warmer, and more particularly, to one that contains a plate exclusively for holding a candle to keep a cup placed on the plate warmed for a longer time by burning the candle and air convection.

[0003] (b) Description of the Prior Art

[0004] In bitter cold season or area, coffee, tea or wine usually winds up ice cold in no time before one can really enjoys a cup of hot drink. There are heating devices operating on electricity generally available in the market to keep the hot drink warming. However, those devices works by using electric heating coils or devices that generate heat when conducted, and the contents in the cup is indirectly heated; furthermore, as limited by the length of the power cord, they are prevented from been carried around as one desires.

SUMMARY OF THE INVENTION

[0005] The primary purpose of the present invention is to provide a cup warmer to directly and indirectly keep the cup, thus the contents in the cup warmed for a longer time. To achieve the purpose, the present invention exclusively adapted for burning candle as its heat source, is essentially comprised of a support having its bottom and top respectively provided with a base and a warming plate. Wherein, spacing is provided below the support (or multiple ventilation pores are provided on the support) to admit air. A candle plate is provided on the base, and a central opening and multiple air guide passages are provided on the warming plate. Therefore, while the candle is burning, air convection takes place in the spacing at the bottom of the support. The heat passes through the central opening and those air guide passages to directly and indirectly keep the cup, thus the contents in the cup warmed for a longer time.

[0006] Another purpose of the present invention is to provide a cup warmer; wherein, the base at the bottom of the support is either integrated with support or separately provided. That is, the base is directly integrated to the bottom of the support, or attached to the bottom of the support by means of insertion, locking, adhesion or packing.

[0007] Another purpose yet of the present invention is to provide a cup warmer; wherein, a tray is provided at the center of the base at the bottom of the support for the placement of a candle plate; and a layer of refractory material is paved on the tray to isolate it from the candle plate to ensure that the base will not be overheated.

[0008] Another purpose yet of the present invention is to provide a cup warmer; wherein, the base at the bottom of the support relates to a hollowed frame, and multiple feet are provided below the frame to define a proper spacing for admitting the ambient air. The height of the foot is made greater than the depth of the tray so to keep the tray a certain distance from the surface where the cup warmer is placed (e.g., desk top) without directly contacting the surface for better insulation effect.

[0009] Another purpose yet of the present invention is to provide a cup warmer; wherein, a heat fender is provided continuously or intermittently surrounding the inner circumference of the central opening of the warming plate at where between any two abutted air guide passages of the warming plate on top of the support. The heat from the burning candle as restricted by the heat fender is concentrated to be guided through and released out of the central opening and those air guide passages of the warming plate, thus to prevent the support from being overheated.

[0010] Another purpose yet of the present invention is to provide a cup warmer; wherein, the warming plate is pivoted to the support so that the warming plate can be lifted up to facilitate the placement and replacement of the candle plate into the base.

[0011] Another purpose yet of the present invention is to provide a cup warmer; wherein, the cup is placed on the warming plate provided on the top of the support, and one or more than one air guide pore is provided on the warming plate at where close to the respective air guide passage is provided. The air guide pore being connected through the air guide passage also leads the heat to warm the cup on the warming plate.

[0012] Another purpose yet of the present invention is to provide a cup warmer; wherein, the air guide passage provided to the warming plate on top of the support extends upward inside out at a certain inclination to facilitate guiding the heat to rise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Referring to FIGS. 1 and 2, a preferred embodiment of a cup warmer of the present invention is essentially comprised of a support 1, a base 2 and a warming plate 3; wherein,

[0023] the support 1, related to a hollow body having at its bottom and top respectively adapted with the base 2 and the warming plate 3; one or more than one recess 11 being provided on the upper circumference, and one or more than one holes 12 is provided on the peripheral wall for the candle light to be emitted for adding romantic atmosphere to the environment;

[0024] the base 2, being provided at the bottom of the support 1, either integrated with or provided separately from the support 1; as illustrated, a standalone base 2 is attached to the bottom of the support 1 by means of insertion, locking, adhesion or packing, a tray 21 is provided at the center of the base 2 to receive the placement of a candle plate 4; a layer of refractory material 211 is paved on top of the tray 21 to isolate the heat from the candle plate so to prevent the base 2 from being overheated; the base 2 may be provided in the form of a hollowed frame and multiple feet being provided below the frame to define a proper spacing to admit the air; the height of each foot 22 is greater than the depth of the tray 21 so to keep a proper spacing between the tray 21 and the surface the cup warmer is placed upon (e.g., desktop) for better insulation effect; and multiple retainers 23 being provided on the peripheral wall of the tray to help the candle plate 4 staying in position whenever the cup warmer is moved around; and

[0025] the warming plate 3, made of refractory material (e.g., metal, ceramic or vitreous material), having a flushed surface 31, a central opening 32, and one ore more than one air guide passage 33 to match the recess 11, and one or more than one air guide pore 34 being provided close to and connected through its corresponding air guide passage 33; and a heat fender 35 being provided continuously or intermittently surrounding the inner circumference of the central opening 32 at where between any two abutted air guide pore 34 for the heat to be concentrated and released through the central opening 32, the air guide passage 33 or the air guide pore 34 to create air convection.

[0026] As illustrated in FIG. 3, a cup 5 us placed on the surface 31 of the cup warmer 3. Air required for burning the candle is supplied from the bottom of the support 1, and the heat from the burning candle passes through the central opening 32, the air guide passage 33 or air guide pore 34 to maintain directly and indirectly warming the cup 5, thus to keep the contents (e.g., coffee, tea, wine or fragrant essence) in the cup 5 warmed for a longer time.

[0027] A proper spacing is defined between the support 1 and the surface the cup warmer is placed upon due to the base 2 is provided at the bottom of the support 1 to admit the air for maintaining better air convection when the candle is burning. Similarly, as illustrated in FIG. 4 for another preferred embodiment of the present invention, one or more than one pores 36 that permits air convection is forthwith provided on the peripheral wall at the bottom of the support 1 to achieve the same air convection effect.
