1. Field of Invention
The present invention relates to an apparatus for daily use, and more particularly, to an electrically heated towel rack capable of generating heat when powered by electricity for heating towels or preserving the temperature thereof.
2. Description of Related Art
In daily life, wet towels, after being used, may lead to growth of bacteria, which is bad to human health. In winter, especially in the north, cold weather often makes clothes and towels cold and therefore uncomfortable to use. For such reasons, electrically heated towel racks have been designed. These electrically heated towel racks have an electric heating unit installed therein. The electric heating unit, when being powered by electricity, increases the temperature of a heat conduction tube thereof so as to heat towels.
Currently, most electrically heated towel racks in the market have a heating circuit that includes a heating wire. The heating wire suffers from disadvantages of low heating efficiency and low heat endurance so that frequent maintenance needs to be made to the heating wire in the electrically heated towel rack.
It is an object of the present invention to provide an electrically heated towel rack having an electric heating unit that has a long lifetime, good endurability, a large heating area and multiple working states. In one of the working states wet towels after being used can be hanged on the electrically towel rack to be quickly heated, and in another working state towels and clothes can be disposed thereon.
To achieve the above object, a preferred embodiment of the present invention provides an electrically heated towel rack that includes two parallel retractable arms and an electric heating board. Each of the retractable arms has a fixed portion and a retractable portion. A connecting member is disposed at an end of the fixed portion for connecting the fixed portion and a wall. Two axial holes or short axles are symmetrically and respectively disposed on inner sides of the retractable portions of the two retractable arms. Two short axles or axial holes are correspondingly disposed on two ends and close to a side of the electric heating board respectively. The short axles/axial holes on the two ends of the electric heating board are engaged with the axial holes/short axles on the inner sides of the retractable portions of the two retractable arms so that the electric heating board is rotatably supported between the two retractable arms. Two support members are respectively disposed on the inner sides of the retractable portions of the two retractable arms. The distance between each of the support members and the axial hole/short axle on the inner side of the retractable arm where the support member resides is less than the width of the electric heating board.
The electrically heated towel rack uses the electric heating board to load towels and clothes. When powered by electricity, the electric heating board can generate heat to heat the towels and the clothes disposed thereon. The electrically heated towel rack has a simple structure and an elegant look. In addition, the electric heating board has a long lifetime, good endurability, a large heating area.
The electric heating board can be rotated to a horizontal position so that towels and clothes can be disposed thereon. The distance between the electric heating board and the wall can be adjusted by pushing or pulling the retractable portion so that larger towels can be disposed on the heated towel rack as well. Alternatively, the electric heating board can be rotated to a vertical position so that towels can be disposed thereon unfolded and thereby heated quickly.
Other advantages and novel features will be drawn from the following detailed description of preferred embodiment with the attached drawings.
Referring to
The retractable arm 1 (or 1′) can have a structure in which the retractable portion 14 is covered inside the fixed portion 12. With this structure, because the retractable portion 14 is inside the fixed portion 12, a hole needs to be formed on the fixed portion 12 so that the retractable portion 14 with the support member can glide inside the fixed portion 12. More specifically, the fixed portion 12 of the retractable arm 1 has a tube structure with a slot hole on a side thereof. The retractable portion 14 of the retractable arm 1 is slidably inserted to the tube shaped fixed portion 12. The support member 13 on the retractable portion 14 sticks out from the slot hole on the side of the tube shaped fixed portion 12. The fixed portion 12 of the retractable arm 1 can be a cylindrical tube, an elliptical tube or a cubical tube with a slot hole on a side thereof. In this embodiment, the fixed portion 12 of the retractable arm 1 is a cubical tube with a slot hole on a side thereof.
The retractable arm 1 (or 1′) can have a structure in which the fixed portion 12 is covered inside the retractable portion 14. For example, the retractable portion 14 has a tube structure and is slidably configured in the fixed portion 12 of the retractable arm 1 (or 1′). The axle hole for installing the electric heating board 2 is formed close to a front end of the tube shaped retractable portion 14. The support member 13 is disposed close to a back end of the tube shaped retractable portion 14. The retractable portion 14 of the retractable arm 1 can be a cylindrical tube, an elliptical tube or a cubical tube.
In another embodiment, the retractable arm 1 and 1′ can be replaced by non-retractable pieces under which sliding extension of the towel rack is not required. The support members 13 can be replaced by a bar connecting the two non-retractable arms close to their back ends.
The electric heating board 2 can be a glass electric heating board including two glass plates of identical sizes sticking to each other. The plates can also be made of other suitable materials. A conductive film is deposited on an inner side of at least one of the glass plates. Two electrode stripes are disposed between the glass plates close to the left and right, or the upper and lower edges of the glass plates. Both of the electrode stripes are electrically connected with the conductive film and to an AC power supply through a wire. The wire can be disposed inside the retractable arms 1 and 1′ to make a more compact appearance. The power supply used in this embodiment can be a DC power supply as well. At 12V D.C. voltage, a temperature of 50° C. can be reached and maintained, and at 18V D.C. voltage, a temperature of 70° C. can be reached and maintained.
Clipper 21, which includes short axles on two ends thereof, can be installed to the two ends of the electric heating board 2 so as to install the short axles to the electric heating board 2. The clippers 21 are fixed on the electric heating board 2 through bolts and nuts.
In this embodiment, by installing short axles on the electric heating board 2 and forming the corresponding axial holes on the retractable arms 1 and 1′, the electric heating board 2 can be rotatably supported between the two retractable arms 1 and 1′. It is to be understood that alternatively the axial holes can be formed on the electric heating board 2 and the corresponding short axles can be installed on the retractable arms 1 and 1′ so that the electric heating board 2 can be rotatably supported between the two retractable arms 1 and 1′ as well.
