Description

Technical Field

[0001] The utility model relates to a fixing structure for preventing abnormal noise of a heating pipe of an electric heater. Background Art

[0002] Electric heaters can be widely used in various civil and public buildings such as residential buildings, offices, hotels, shopping malls, hospitals, schools, train carriages, mobile heating, simple mobile houses, etc.

[0003] The cover of the electric heater is generally made of aluminum (aluminum alloy). Since aluminum deforms greatly after being heated, the heating tube used to provide heat source is generally installed in the mounting groove of the upper cover. At room temperature (when not in use), the heating tube and the mounting groove are tightly fitted, but when in use (after heating), the gap between the mounting groove and the heating tube will become larger, and the higher the temperature, the larger the gap; causing the heating tube to oscillate after heating and hit the side wall of the mounting groove, making a rattling noise, which can easily cause users to mistakenly believe that the electric heater is damaged. Utility Model Content

[0004] The utility model aims to provide a fixing structure for preventing abnormal noise of a heating tube of an electric heater, which helps to press the heating tube tightly into a mounting groove to prevent abnormal noise from occurring during use of the heating tube.

[0005] The technical solution of the utility model is: a fixing structure for preventing abnormal noise of the heating tube of an electric heater, comprising an upper cover, the inner wall of the upper cover is provided with a longitudinal installation groove along its length direction, the heating tube is inserted in the longitudinal installation groove, and a pressure plate is provided in the upper cover shell to press on the lower side of the heating tube.

[0006] Furthermore, the longitudinal mounting groove is composed of a pair of arc-shaped plates with arc openings facing each other, the upper ends of the arc-shaped plates are connected to the upper cover shell as a whole, and a groove is formed between the lower ends of the two arc-shaped plates.

[0007] Furthermore, a transverse convex plate is provided on one side outer wall of the longitudinal installation groove along the length direction, one end of the pressing plate is fixedly connected to the transverse convex plate, and the other end of the pressing plate is pressed on the lower side of the heating tube.

[0008] Furthermore, an anchor hole is provided at one end of the pressing plate, and the pressing plate is anchored and connected to the transverse convex plate via an anchor nail passing through the anchor hole and the transverse convex plate.

[0009] Furthermore, the pressing plate is L-shaped, and at least one pressing plate is arranged on each heating tube; the number of the heating tubes is more than two, and they are arranged at intervals.

[0010] Furthermore, a heat insulation board is arranged in the upper cover shell at the lower side of the heating tube along the length direction.

[0011] Furthermore, longitudinally arranged radiating ridges are arranged at intervals along the width direction on the upper side surface of the upper cover.

[0012] Furthermore, the upper cover is made of aluminum and has threaded holes at both ends.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The structure is simple and compact, which helps to press the heating tube tightly into the installation groove, preventing the heating tube from making abnormal noises due to the enlarged installation gap when the electric heater is in use. At the same time, it effectively reduces costs.

[0015] 2. Installing a heat shield inside the upper housing helps reduce the amount of heat that enters the lower housing.

[0016] 3. The upper side of the upper cover is provided with longitudinally arranged radiation ridges at intervals along the width direction, which helps to better radiate heat. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0021] refer to Figure 1 To Figure Figure 2

[0022] A fixing structure for preventing abnormal noise of a heating pipe of an electric heater comprises an upper cover 1 for connecting with a lower cover shell 5 in the electric heater, a longitudinal mounting groove 11 is arranged on the inner wall of the upper cover along its length direction, a heating pipe 2 is inserted in the longitudinal mounting groove, and a pressing plate 3 is arranged in the upper cover shell to press on the lower side of the heating pipe. Thus, the pressing plate provides a pressing force to the heating pipe, so that the heating pipe is always in contact with a side wall of the longitudinal mounting groove, which helps to avoid abnormal noise caused by an enlarged gap.

[0023] In this embodiment, the longitudinal installation groove is composed of a pair of arc-shaped plates 12 with arc openings facing each other, the upper ends of the arc-shaped plates are integrally formed with the upper cover shell, and a notch is formed between the lower ends of the two arc-shaped plates, which helps to insert the heating tube into the longitudinal installation groove.

[0024] In this embodiment, a transverse convex plate 13 is provided on one side outer wall of the longitudinal installation groove along the length direction, one end of the pressing plate is fixedly connected to the transverse convex plate, and the other end of the pressing plate is pressed on the lower side of the heating tube.

[0025] In this embodiment, an anchor hole is provided at one end of the pressing plate, and the pressing plate is anchored and connected to the transverse convex plate through an anchor nail 31 passing through the anchor hole and the transverse convex plate. The pressing plate does not contact the arc plate on the same side thereof, so as to better press the heating tube.

[0026] In this embodiment, the pressing plate is L-shaped, and at least one pressing plate is provided on each heating tube. The pressing plate and the heating tube have two pressing blocks (pressing parts) at the ends thereof, so as to improve the stability of contact with the heating tube. The number of the heating tubes is more than two, and they are arranged at intervals.

[0027] In this embodiment, a heat insulation plate 4 is provided along the length direction at the lower side of the heating tube in the upper cover shell, which helps to confine the heat in the cavity of the upper cover and reduce the heat entering the lower cover shell of the electric heater.

[0028] In this embodiment, longitudinally arranged radiation ridges 14 are provided at intervals on the upper side surface of the upper cover along the width direction, which helps to better radiate heat.

[0029] In this embodiment, the upper cover is made of aluminum (such as aluminum alloy), and threaded holes 15 are provided at both ends to facilitate connection with end plates and the like.

[0030] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0031] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0032] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0033] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
