The present disclosure relates to the technical field of bath products, in particular to a heating plate of a towel rack.
Electric towel rack, as a bath product, is used to dry wet towels or cloths by an electric heating mode. Bacteria are prone to breed on the wet towel that hung in a closed and damp bathroom for a long time, causing that the wet towel smells bad. Therefore, regular drying and disinfecting towels hung on the towel rack are in great demand. Most of the electric towel racks on the market heat the wet towels in a drying and heating mode. In the drying and heating mode, an intermediary is adopted to transfer heat to a periphery of the electric towel rack or transfer heat into the electric towel rack, to dry the wet towels or cloths. The drying and heating mode has disadvantages such as low heat utilization efficiency and large power consumption.
In view of the above, a technical problem to be solved by the present disclosure is to provide a heating plate that improve the heat utilization efficiency and reduce the power consumption.
In one aspect, the present invention discloses a heating plate, applied to a towel rack. The heating plate includes a body for hanging wet towels or cloths. The body includes a hollow metal housing, at least one receiving element fixedly received in the metal housing, and a metal heating wire, the metal heating wire is received in the receiving element and forms a heating circuit loop.
Furthermore, the receiving element defines a through hole through which the metal heating wire passes.
Furthermore, an outer surface of the metal heating wire is sealingly connected with an inner wall of the through hole.
Furthermore, the metal heating wire is received in the through hole in a clearance fit mode.
Furthermore, the metal heating wire is received in the through hole in an interference fit mode.
Furthermore, the heating plate further includes at least one rib, configured to connect an inner wall of the metal housing with an outer wall of the receiving element.
Furthermore, the rib, the receiving element, and the metal housing are integrated formed.
Furthermore, a cross-section of the receiving element is a circle, a square, or a polygon.
Furthermore, a wall of the through hole defines at least one notch.
Furthermore, the wall of the through hole defines at least two notches spaced apart from each other.
Furthermore, the at least one receiving element includes at least two receiving elements, a gap is defined between each two adjacent receiving elements.
Furthermore, the heating plate further includes at least two ribs, configured to connect an inner wall of the metal housing with outer walls of the receiving elements.
Furthermore, two ends of the metal heating wire are exposed from the metal housing, and arranged at a same side of the hollow metal housing. Furthermore, the metal housing is made of aluminum or aluminum alloy.
Furthermore, the heating circuit loop has a reticular shape or a grid shape.
Furthermore, the metal heating wire is a carbon fiber heating wire, a resistance heating wire, or a conductive metal heating wire.
In the technical solution of the present disclosure, the heating plate includes a hollow metal housing, at least one receiving element fixedly received in the metal housing, and a metal heating wire, the metal heating wire is received in the receiving element and forms a heating circuit loop. When in use, the heating circuit loop generates a large amount of heat, and the heat is transmitted to a surface of the metal housing of the heating plate to dry the towels and cloths hung on the metal housing. As the heat generated by the heating circuit loop is transmitted to the metal housing directly, the heating plate of the present disclosure has the advantages of high heat utilization efficiency and low power consumption.
The technical solutions of the present disclosure are further described in detail below with reference to the accompanying drawings and embodiments.
In the following, the technical schemes in the embodiments of the present application will be described clearly and completely with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of embodiments of the present application, not all of the embodiments.
