Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to an electric water heating radiator. Background Art

[0002] As a heat conduction device, radiator is widely used in daily life, such as as a heating device, so this type of radiator is also generally called radiator.

[0003] In the related art, some radiators have built-in electric heating components, which are used to directly heat the water in the radiator to achieve heating. Such radiators are generally also called electric water heating radiators.

[0004] However, the existing electric water heating radiators with built-in electric heating components are mainly tube radiators, because the built-in electric heating components require sufficient space inside the radiator to install the electric heating components. For the tube radiator, its main structure is in the form of a pipe, so the space inside the pipe is sufficient to install the electric heating components.

[0005] This is not the case with plate-type radiators, because the flow channel of plate-type radiators is mainly arranged in the waterway plate, and the waterway plate itself is relatively thin and not enough to accommodate electric heating components, so it is difficult to build in electric heating components. Based on this, how to design a plate-type electric water-heating radiator that can have built-in electric heating components has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0026] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0027] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0028] See also Figure 1-6 As shown, this embodiment provides an electric water heating radiator, which is mainly a plate radiator, which mainly includes two oppositely arranged waterway plates 1; the waterway plate 1 has a waterway for holding water inside (not shown in the figure), so that the waterway plate 1 is equivalent to a container for holding water. When the water in the waterway is heated, the heat can be transferred to the waterway plate 1, and dissipated by the waterway plate 1 to achieve heating.

[0029] In addition, in order to improve the heat dissipation effect, heat dissipation fins 11 are provided on the opposite side walls of the two water channel plates 1 .

[0030] like Figure 2 As shown, the radiator further includes an external tube body 2 and an electric heating component 3. In this embodiment, the external tube body 2 is arranged on one side of the waterway plate 1 and extends along the height direction of the waterway plate 1.

[0031] The water channels in the two water channel plates 1 are connected to the external tube body 2, and one end of the external tube body 2 is closed, and the other end serves as the insertion end 20 of the electric heating component 3. For example, in this embodiment, the lower end of the external tube body 2 is closed, and the upper end is open as the insertion end 20.

[0032] like Figure 3 and Figure 5 As shown, the electric heating component 3 includes a heating device 31 that can generate heat when powered on. The heating device 31 is inserted into the external tube body 2 through the insertion end 20 to heat the water in the external tube body 2, and the electric heating component 3 closes the insertion end 20 to prevent water leakage from the insertion end 20.

[0033] Through the above arrangement, when in use, water is first injected into the external tube body 2 through the insertion end 20, and the water can flow into the waterway from the external tube body 2; after the water injection is completed, the electric heating component 3 is installed and powered, so that the heating device 31 of the electric heating component 3 starts to generate heat to heat the water in the external tube body 2, and because the external tube body 2 is connected to the waterway, the water in the waterway will also be heated, and the heated water will dissipate the heat to the environment through the waterway plate 1 to achieve heating.

[0034] It can be seen that in the present embodiment, the electric heating component 3 is installed through the external tube body 2 so that the external tube body 2 serves as a direct heating area, so that the installation of the electric heating component 3 is no longer limited by the thickness of the waterway plate 1, because the electric heating component 3 is installed in the external tube body 2, and its internal space is sufficient to install the electric heating component 3; when in use, the electric heating component 3 directly heats the water in the external tube body 2, and the external tube body 2 is connected to the waterway in the waterway plate 1, so that the water in the waterway plate 1 can also be heated, thereby achieving the effect of electric water heating.

[0035] In this embodiment, in order to be able to disassemble and assemble the electric heating component 3, in this embodiment, the electric heating component 3 is detachably installed in the external tube body 2.

[0036] like Figure 3 , Figure 5As shown, the electric heating component 3 further includes a head, which is threadedly connected to the insertion end 20 of the external tube body 2; a first sealing ring 21 is embedded between the head and the insertion end 20 of the external tube body 2. For example, in this embodiment, the electric heating component 3 adopts an electric heating rod, the rod body portion of the electric heating rod constitutes the aforementioned heating device 31, and the head end portion of the electric heating rod constitutes the aforementioned head.

[0037] The specific connection method between the electric heating component 3 and the external tube body 2 is that the head includes a cover portion 322 and a shaft portion 321 fixed on one side of the cover portion 322, the shaft portion 321 is inserted into the external tube body 2 along the axial direction of the external tube body 2, an external thread is provided on the outer circumferential wall of the shaft body, and an internal thread is provided on the inner circumferential wall of the insertion end 20 of the external tube body 2, and the threaded connection between the external tube body 2 and the shaft portion 321 is realized by rotating and screwing the external thread and the internal thread.

[0038] like Figure 6 As shown, the heating device 31 is coaxially fixed at the lower end of the shaft portion 321; the diameter of the cover portion 322 is larger than the diameter of the shaft portion 321, so that the cover portion 322 radially extends out of the shaft portion 321 to form a step surface 3221 between the cover portion 322 and the shaft portion 321, which is used to compress the first sealing ring 21; the first sealing ring 21 is compressed between the upper end wall of the insertion end 20 and the step surface 3221 to achieve sealing.

[0039] In this embodiment, the specific connection structure between the water channel of the water channel plate 1 and the external pipe body 2 is as follows:

[0040] like Figure 3 As shown, two water inlet pipes 5 are provided on the same side of the waterway plate 1. Both water inlet pipes 5 are T-shaped three-way pipes, both ends of which are respectively fixed to the waterway plate 1 and connected to the waterway in the waterway plate 1; the other end serves as a docking end 51.

[0041] The two water inlet pipes 5 are arranged in sequence and spaced apart along the height direction of the waterway plate 1 .

[0042] like Figure 3 As shown, two pipe heads 22 are provided on the side of the external pipe body 2 for docking with the docking ends 51 of the two water inlet pipes 5 respectively, and the pipe heads 22 are connected to the inside of the external pipe body 2; that is, one pipe head 22 corresponds to one water inlet pipe 5.

[0043] In this embodiment, the pipe heads 22 are connected to the water inlet pipe 5 through a joint.

[0044] When the vertical distance between the butt ends 51 of the two water inlet pipes 5 is equal to the vertical distance between the two pipe heads 22 , both joints may be conventional straight-through joints.

[0045] However, in actual applications, the spacing between the butt joints of the two water inlet pipes 5 of radiators of different models is slightly different, which makes it difficult for the external tube body 2 to adapt to various models of radiators. Therefore, in this embodiment, among the two joints, the lower joint adopts the existing straight-through joint, which is coaxially butt-jointed between the lower end pipe head 22 and the butt end 51 of the water inlet pipe 5.

[0046] The upper joint adopts an eccentric joint 6, such as Figure 3 and Figure 4 As shown, the eccentric joint 6 includes a first joint 61, a second joint 62 and a locking member.

[0047] like Figure 4 and Figure 6 As shown, the first connector 61 includes a first interface 611 and a second interface 612, the first interface 611 and the second interface 612 are axially parallel and radially offset from each other, that is, the central axis L1 of the first interface 611 and the central axis L2 of the second interface 612 are parallel to each other, and the central axes of the two are radially offset and are in a non-coaxial state.

[0048] In the assembled state, Figure 6 As shown, the first interface 611 is inserted into the end of the tube head 22 and threadedly connected to the end of the tube head 22. Specifically, an internal thread is provided on the inner circumferential wall of the tube head 22, and an external thread is provided on the outer circumferential wall of the first interface 611. The threaded connection between the first interface 611 and the tube head 22 is achieved by screwing the external thread and the internal thread together.

[0049] One end of the second joint 62 is inserted into and threadedly connected to the butt end 51 of the water inlet pipe 5. For example, an internal thread is provided on the inner circumferential wall of the butt end 51 of the water inlet pipe 5, and an external thread is provided on the outer circumferential wall of the second joint 62. The threaded connection between the internal thread and the external thread is achieved by screwing together the internal thread and the external thread.

[0050] In addition, in order to limit the depth of the second joint 62 inserted into the butt end 51 of the water inlet pipe 5, a limit ring 622 is provided on the outer peripheral wall of the second joint 62. In addition, a third sealing ring 623 is embedded between the outer peripheral wall of the second joint 62 and the butt end 51 of the water inlet pipe 5.

[0051] The other end of the second joint 62 is inserted into the second interface 612 and connected to the second interface 612; the locking piece is arranged between the first joint 61 and the second joint 62 to tighten the first joint 61 and the second joint 62 in the axial direction toward each other. In addition, in order to improve the sealing between the second joint 62 and the second interface 612, in this embodiment, a second sealing ring 64 is embedded between the second interface 612 and the second joint 62.

[0052] The locking member is preferably a nut 63, which is threadedly connected to the outer wall of the second interface 612. For example, a threaded section matching the thread of the nut 63 is provided on the outer wall of the second interface 612, and the nut 63 can be moved axially along the second interface 612 by rotating the nut 63.

[0053] like Figure 4 and Figure 6 As shown, a circle of bosses 631 is formed on the inner circumferential wall of one end of the nut 63 close to the second joint 62, and a convex ring 621 is provided on the outer circumferential wall of the second joint 62; the bosses 631 abut against the side wall of the convex ring 621 away from the first joint 61. In this way, when locking is required, the nut 63 is rotated to move the nut 63 toward the side of the external tube body 2, so that the bosses 631 on the nut 63 also move in the same direction, and finally hook against the convex ring 621 on the side of the convex ring 621 away from the tube head 22, thereby tightening the second interface 612 and the second joint 62.

[0054] In addition, if Figure 1 As shown, a cover plate 4 is provided on the outer side of the external tube body 2 , and the cover plate 4 is fixed on the waterway plate 1 to shield the external tube body 2 on the peripheral side of the external tube body 2 .

[0055] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
