[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, an electric heater assembly 10 is provided, comprising an oil radiator heating plate 11 and a humidifying device 12. The oil radiator heating plate 11 is provided with a mounting position 111, the mounting position 111 is located at the highest water level of the oil in the oil radiator heating plate 11, and the humidifying device 12 is mounted on the mounting position 111, and is used to utilize the high temperature of the oil radiator heating plate 11 to realize the humidification process.

[0036] During use, the humidifying device 12 is installed at the installation position 111 of the oil radiator heating plate 11, that is, the humidifying device 12 is set at the position of the highest temperature when the oil radiator heating plate 11 is working, so that the high temperature of the oil radiator heating plate 11 is used to evaporate the moisture in the humidifying device 12, humidify, and improve the humidification effect.

[0037] Specifically, the humidifying device 12 is a device containing water, and the water contained therein can evaporate to perform humidification in a high temperature environment.

[0038] The humidifying device 12 can be installed in a fixed manner or in a detachable manner at the installation position 111 on the oil radiator heating plate 11. The detachable installation method makes it easy to remove the humidifying device 12 and perform water addition and other operations.

[0039] The specific detachable manner of the humidifying device 12 at the installation position 111 is not specifically limited here.

[0040] For example, in one embodiment, Figure 1 As shown, the oil radiator heating plate 11 is provided with a limiter 112. Figure 3 As shown, the humidifying device 12 includes two inserting parts 121 arranged opposite to each other and a connecting part 122 connected between the two inserting parts 121. Figure 1 As shown, the two insertion parts 121 can be respectively inserted into the two sides of the oil radiator heating plate 11 , and the limiting member 112 can limit the humidifying device 12 at the installation position 111 .

[0041] That is, the humidifier 12 is detachably installed in the installation position 111 by plugging, and under the limiting action of the limiting member 112, it is ensured that the humidifier 12 can be reliably located in the installation position 111 without slipping down. When it is not needed, the humidifier 12 can be kept in the installation position 111, so that the humidifier 12 can be prevented from being lost. Of course, when it is necessary to clean or add water, the humidifier 12 can also be pulled out and removed from the oil heater heating plate 11, and the operation process is simple and convenient.

[0042] More specifically, in one embodiment, Figure 1 As shown, the limiting member 112 includes a convex bump, and the convex bump protrudes from both sides of the oil radiator heating plate 11, and the distance between the two insertion parts 121 is not greater than the thickness of the convex bump in the lateral direction.

[0043] When the two insertion parts 121 of the humidifying device 12 are respectively inserted into the two sides of the oil radiator heating plate 11, based on the fact that the distance between the two insertion parts 121 is not greater than the lateral thickness of the convex bump, the humidifying device 12 cannot slide down and always maintains the height of the highest water level of the oil, making full use of the highest temperature of the oil radiator heating plate 11 during heating to improve the humidification effect.

[0044] The horizontal in this case refers to Figure 1 The horizontal direction is the horizontal direction under the viewing angle shown, and the vertical direction is the horizontal direction under the viewing angle shown. Figure 1 Portrait orientation at the viewing angle shown.

[0045] More specifically, Figures 3 to 6 As shown, in one embodiment, the two insertion parts 121 are arranged relatively parallel, and the connecting part 122 connects the two insertion parts 121 to form a U-shaped structure. After the humidifier 12 is installed in the installation position 111, the two insertion parts 121 are in contact with two side surfaces of the oil heater heating plate 11 respectively.

[0046] Specifically, Figure 3 As shown, in one embodiment, the humidifying device 12 includes a shell that encloses the U-shaped structure, and a cavity for containing water is formed in the shell, and the cavity is a U-shaped cavity 125 corresponding to the U-shaped structure.

[0047] That is, the cavity for containing water in the humidifying device 12 is surrounded by the shell, and since the cavity is a U-shaped cavity 125, the whole is a connected structure, so the water adding process is more convenient.

[0048] Furthermore, if Figures 3 to 6 As shown, in one embodiment, the wall on the shell located on the inner side of the U-shaped cavity 125 is the inner wall, and the portion of the inner wall used to form the connecting portion 122 is the inner connecting wall. The inner connecting wall is provided with a strip groove 126, and the strip groove 126 is distributed along the longitudinal direction of the oil-filled radiator heating plate 11, and the oil-filled radiator heating plate 11 can be stuck in the strip groove 126.

[0049] When the humidifier 12 is inserted into the oil-filled heater heating sheet 11, the oil-filled heater heating sheet 11 can be stuck in the strip groove 126, which proves that the humidifier 12 has been installed in place. Moreover, the provision of the strip groove 126 also makes the relative position between the oil-filled heater heating sheet 11 and the humidifier 12 more stable. In order to facilitate the insertion of the insertion portion 121 to the side of the oil-filled heater heating sheet 11, the spacing between the two insertion portions 121 is preferably slightly larger than the thickness of the oil-filled heater heating sheet 11. However, after the humidifier 12 is inserted into place, the relative position between the oil-filled heater heating sheet 11 and the humidifier 12 needs to be stable in order to ensure the reliable implementation of the humidification process. Therefore, the strip groove 126 is provided so that the oil-filled heater heating sheet 11 can be stuck in the strip groove 126 to ensure the stability of the relative position between the two and prevent the humidifier 12 from falling.

[0050] Specifically, the strip groove 126 may be a groove dug longitudinally on the inner connecting wall, or may be a groove as shown in FIG. Figure 5 As shown, the groove is formed by a plurality of pairs of relatively spaced limiting protrusions distributed along the longitudinal direction.

[0051] More specifically, if Figure 3 As shown, in one embodiment, the shell includes a shell body 123 and a shell cover 124 detachably connected to the shell body 123. The shell body 123 includes a U-shaped outer wall, a U-shaped inner wall and a bottom wall, the U-shaped outer wall is arranged outside the U-shaped inner wall, the bottom wall is arranged at the bottom of the U-shaped inner wall and the U-shaped outer wall, and the shell cover 124 is covered on the top surface of the U-shaped inner wall and the U-shaped outer wall. That is, the shell is composed of the shell cover 124 and the shell body 123.

[0052] Specifically, the shell cover 124 and the shell body 123 can be detachably connected by a snap-fit ​​connection.

[0053] When the strip groove 126 is provided on the inner connecting wall, part of the strip groove 126 is formed on the U-shaped inner wall, and the strip groove 126 passes through the shell cover 124 in the longitudinal direction, that is, Figure 4 and Figure 5 As shown, both the shell cover 124 and the shell body 123 are provided with depressions, which together form the strip groove 126. Moreover, in order to avoid interference, the width of the depression on the shell cover 124 can be set slightly larger.

[0054] Further, in one embodiment, if Figure 3 and Figure 4 As shown, the shell cover 124 is provided with a humidifying hole 1241 . The water vapor heated and evaporated in the U-shaped cavity 125 is discharged from the humidifying hole 1241 .

[0055] Furthermore, if Figure 3 As shown, in one embodiment, a circle of convex ribs 1242 is provided at the edge of the top surface of the shell cover 124, and the convex ribs 1242 surround the humidification hole 1241 inside. Therefore, when water is added to the U-shaped cavity 125 through the humidification hole 1241, the convex ribs 1242 can effectively prevent water from leaking out.

[0056] Furthermore, if Figure 1 As shown, in one embodiment, the distance between the stopper 112 and the upper oil passage 113 of the oil radiator heating plate 11 is not less than the longitudinal height of the humidifying device 12 , so that the humidifying device 12 can be inserted into the installation position 111 .

[0057] Further, in one embodiment, if Figure 1 As shown, there are multiple oil-filled radiator heating sheets 11 , which are spaced apart in the transverse direction, and the thickness of the inserting portion 121 in the transverse direction is not greater than the spacing between two adjacent oil-filled radiator heating sheets 11 .

[0058] When there are multiple oil-filled radiator heating sheets 11 , the thickness of the insertion portion 121 in the lateral direction is not greater than the distance between two adjacent oil-filled radiator heating sheets 11 , thereby ensuring that the insertion portion 121 can be inserted between two adjacent oil-filled radiator heating sheets 11 .

[0059] When there are multiple oil-filled radiator heating plates 11, multiple humidifying devices 12 may be provided to further improve the humidification efficiency.

[0060] For example, in one embodiment, there are multiple humidifiers 12, each of which is inserted on the oil radiator heating sheet 11, and there is one oil radiator heating sheet 11 between adjacent humidifiers 12. No humidifier 12 is inserted on the oil radiator heating sheet 11 between two adjacent humidifiers 12.

[0061] That is, there is an oil-filled heater heating plate 11 without a humidifying device 12 inserted between adjacent oil-filled heater heating plates 11 with humidifying devices 12 inserted, and the heat generated at the highest water level of the oil on the oil-filled heater heating plate 11 without a humidifying device 12 inserted can be provided to the humidifying device 12 inserted on the adjacent oil-filled heater heating plate 11.

[0062] Moreover, assuming that the oil-filled radiator heating plate 11 with the humidifying device 12 inserted is defined as the main heating plate, and the two heating plates adjacent to the main heating plate on the left and right are respectively the left heating plate and the right heating plate, then the humidifying device 12 can be limited by the convex bumps on the left heating plate and the right heating plate, that is, the two insertion parts 121 of the humidifying device 12 are respectively limited at the top by the convex bumps on the left heating plate and the convex bumps on the right heating plate to prevent them from sliding down. In this case, the convex bumps do not need to be set on the main heating plate.

[0063] Alternatively, in one embodiment, there are a plurality of inserting parts 121 , each of which is arranged opposite to each other, and a U-shaped groove 127 for accommodating the oil-filled radiator heating plate 11 is formed between every two adjacent inserting parts 121 .

[0064] That is, the humidifying device 12 is a structure including a plurality of inserting parts 121, and each inserting part 121 is connected to the connecting part 122. Therefore, during installation, each of the oil radiator heating plates 11 corresponds to one of the U-shaped grooves 127.

[0065] Further, in another embodiment, if Figures 3 to 6 As shown, a humidifying device 12 is provided, and the humidifying device 12 may be a device having the same structure as the humidifying device 12 in the above-mentioned electric heater assembly 10 .

[0066] Furthermore, in one embodiment, the humidifying device 12 includes two insertion parts 121 arranged opposite to each other and a connecting part 122 connected between the two insertion parts 121, and the two insertion parts 121 can be respectively inserted on both sides of the oil-filled radiator heating plate 11, and the wall on the connecting part 122 opposite to the oil-filled radiator heating plate 11 is the inner wall, and the inner wall is provided with a strip groove 126, and the strip groove 126 is distributed along the longitudinal direction of the oil-filled radiator heating plate 11, and the oil-filled radiator heating plate 11 can be stuck in the strip groove 126.

[0067] When in use, the two insertion parts 121 can be directly inserted into the two sides of the oil heater heating plate 11, and a longitudinally distributed strip groove 126 is provided on the inner wall of the connecting part 122. When the humidifying device 12 is inserted into place on the oil heater heating plate 11, the oil heater heating plate 11 will be stuck in the strip groove 126, thereby completing the installation process, and the operation is simple and convenient. The high temperature environment of the oil heater heating plate 11 is used to achieve the evaporation of water in the humidifying device 12, thereby achieving the humidification effect. In order to further improve the humidification efficiency, the humidifying device 12 can be inserted at the highest water level of the oil on the oil heater heating plate 11. The temperature here is the highest, which can bring the highest temperature environment to the humidifying device 12, increase the speed of water evaporation, and thus improve the humidification efficiency.

[0068] More specifically, in one embodiment, Figure 3 As shown, the humidifying device 12 includes a shell body 123 and a shell cover 124 detachably connected to the shell body 123, the shell body 123 includes a U-shaped outer wall, a U-shaped inner wall and a bottom wall, the U-shaped outer wall is spaced outside the U-shaped inner wall, the bottom wall is arranged at the bottom of the U-shaped inner wall and the U-shaped outer wall, the shell cover 124 is covered on the top surface of the U-shaped inner wall and the U-shaped outer wall to form a U-shaped cavity 125 for holding water, the two long sides of the U-shaped cavity 125 are formed in the insertion part 121, the short side of the U-shaped cavity 125 is formed in the connecting part 122, and the shell cover 124 is provided with a humidifying hole 1241.

[0069] During use, water can be added into the U-shaped cavity 125 after the shell cover 124 is removed from the shell body 123, or water can be added into the U-shaped cavity 125 directly through the humidification hole 1241. During humidification, water vapor is discharged from the humidification hole 1241.

[0070] Furthermore, in yet another embodiment, an electric heater is provided, and the electric heater may be a device having the same structure as the electric heater in the above-mentioned electric heater assembly 10 .

[0071] Furthermore, in one embodiment, the electric heater includes an oil radiator heating plate 11, and a convex bump is provided on the oil radiator heating plate 11, and the convex bump is located below the highest water level of the oil in the oil radiator heating plate 11, so that the humidifying device 12 limited above by the convex bump can be located at the highest water level of the oil. The humidifying device 12 can be the humidifying device 12 described in any of the aforementioned embodiments.

[0072] By setting a convex bump below the highest water level of the oil in the oil radiator heating plate 11, a limiting effect is provided for the humidifying device 12 set on the oil radiator heating plate 11, so that the humidifying device 12 can be located at the highest water level of the oil, thereby utilizing the highest temperature position of the oil radiator heating plate 11 to provide heat for the humidifying device 12, thereby improving the humidification efficiency.

[0073] Of course, the humidifying device 12 may not be provided in the electric heater, and the electric heater may be directly used only for heating.

[0074] Further, in one embodiment, if Figure 1 As shown, there are multiple oil-filled radiator heating sheets 11, and the multiple oil-filled radiator heating sheets 11 are sequentially spaced and distributed in the horizontal direction. On the one hand, the heating effect of the electric heater is improved, and on the other hand, when the humidifying device 12 is arranged on the oil-filled radiator heating sheet 11, multiple humidifying devices 12 can be arranged to improve the humidification effect.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
