Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] In daily life, with the progress of science and technology, electric water heaters have not only the functions of storing water and producing hot water, but also integrate other functions, such as air warming function. However, the existing electric water heaters with air warming function have a large volume and occupy a large space, which is not conducive to installation and use, because the air warming device is combined with the electric water heater.

[0038] Taking the installation of an electric water heater in a bathroom as an example, the original electric water heater combines the air warming device outside the shell of the electric water heater, which occupies a large space in the bathroom, resulting in a lower utilization rate of the already small space in the bathroom.

[0039] Of course, the electric water heater is not limited to being applied to the bathroom, but can also be applied to the kitchen and other spaces, which all have the problem of large space occupation. The embodiments of the present application take the bathroom as an example for analysis.

[0040] In order to meet the needs of users, the electric water heater integrates the air warming module, and compared with the original electric water heater, the volume change is not large, the space occupation does not change greatly, the installation and use are convenient, and the space utilization rate is effectively improved. The embodiments of the present application provide an electric water heater, which fully meets the above requirements.

[0041] Specifically, as shown in the figure, Figures 1 to 10 The embodiments of the present application provide an electric water heater, which includes a shell 1, a decorative cover 2, and an air warming module 3. The shell 1 is hung on the wall of the bathroom. The decorative cover 2 is connected with the shell 1. The inner side of the decorative cover 2 is butted with the inner side of the shell 1 to form an accommodation space. The air warming module 3 is arranged in the accommodation space and embedded on the decorative cover 2.

[0042] According to the structure of the electric water heater, the air warming function is realized in the following way: the decorative cover 2 is provided with an air inlet 21 on the side facing the wall, and is provided with an air outlet 22 on the side away from the wall. In the case of needing heating, the air source flows into the accommodation space from the air inlet 21, is heated by the air warming module 3 to form warm air, and then flows out of the accommodation space from the air outlet 22.

[0043] As shown in the figure, Figures 1 to 2As shown, the shell 1 continues to use the shape of the existing electric water heater, adopts a cylindrical structure, water can be stored in the cylindrical structure, a decorative cover 2 is installed below the shell 1, the decorative cover 2 is in a box shape, a containing space is formed between the lower end of the decorative cover 2 and the lower end face of the shell 1, for installing the air warming module 3, the decorative cover 2 is provided with an air inlet 21 and an air outlet 22 at the front end and the rear end respectively, in order to make the structure of the electric water heater provided by the embodiment of the present application beautiful, the decorative cover 2 and the shell 1 are connected with corresponding radii, compared with the existing electric water heater, only one decorative cover 2 is added in appearance, the volume changes little, and the appearance is beautiful.

[0044] In an optional example, the air warming module 3 provided by the embodiment of the present application includes a first cover plate 31, a second cover plate 32, a fan assembly 33 and a heating element 34, the second cover plate 32 is connected with the first cover plate 31, the shapes of the first cover plate 31 and the second cover plate 32 are as Figures 3 to 4 As shown, the air duct is formed between the first cover plate 31 and the second cover plate 32, the fan assembly 33 is arranged between the first cover plate 31 and the second cover plate 32, and the heating element 34 is arranged between the air outlet 22 and the fan assembly 33, for heating the air source to form warm air. The air warming module 3 adopted by the embodiment of the present application occupies a small space in the three-dimensional structure, is installed in the decorative cover 2 at a moderate position and in the interior, and only the shape of the decorative cover 2 can be seen in appearance, so that the volume of the electric water heater is not affected, and the air warming function is also not affected.

[0045] In a preferred embodiment of the present application, as Figure 5 As shown, the upper and lower end faces and the side faces of the first cover plate 31 and the second cover plate 32 are provided with air holes 300, the air holes 300 arranged on the upper and lower end faces of the first cover plate 31 and the second cover plate 32 are in a honeycomb hole structure or a strip hole structure, and the air holes 300 arranged on the side faces of the first cover plate 31 and the second cover plate 32 are in a large hole structure. Through such arrangement, the air volume of the air source entering the air duct can be increased, the conversion rate of the air source into warm air can be improved, and the air outlet rate of the warm air can be improved.

[0046] In a preferred embodiment of the present application, as Figure 6 As shown, the fan assembly 33 is provided with two, the two fan assemblies 33 are symmetrically arranged in the air duct formed by the first cover plate 31 and the second cover plate 32, and from the front of the electric water heater, the fan assemblies 33 are symmetrically arranged in the two notches of the decorative cover 2. The fan assembly 33 serves as a wind guide structure, can continuously suck the air source into the air inlet 21 of the decorative cover 2 when the air warming function of the electric water heater is started, and blow out the warm air from the air outlet 22 of the decorative cover 2 after the warm air is formed.

[0047] It should be noted that in actual application, the number of fan assemblies 33 can be adjusted by the skilled in the art in appropriate cases, so as to reasonably blow air and ensure that the air volume meets the requirements of the user. Such adjustment and change of the number of fan assemblies 33 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0048] Of course, the present application embodiment symmetrically provides two fan assemblies 33, the air volume is moderate, which basically meets the market demand and does not affect the size of the electric water heater.

[0049] In another preferred embodiment of the present application, the two fan assemblies 33 are provided with air inlet faces 100 and air outlet faces 200, and the air inlet faces 100 and the air outlet faces 200 of the two fan assemblies 33 are reversely arranged.

The air inlet face 100 of the right fan assembly 33 is arranged upward, and the air outlet face 200 is arranged downward. However, the overall air direction does not change, and the air flows from the air inlet 21 to the air outlet 22 of the decorative cover 2.

[0051] It should be noted that in actual application, the two fan assemblies 33 can also be arranged in the same direction. Such flexible adjustment and change do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0052] Further, one side of the air inlet face 100 of the two fan assemblies 33 is provided with an air flow gap 400, as shown in Figure 7 Through such arrangement, the air inlet amount of the air-warming module 3 from the air source can be further improved, so that warm air can be generated in the air-warming mode without air flow interruption.

[0053] In an optional example, the heating element 34 provided by the present application embodiment is a PTC heater, which is clamped between the first cover plate 31 and the second cover plate 32. The first cover plate 31 and the second cover plate 32 are constructed of flame-retardant materials.

[0054] For example, the heating element 34 is a PTC ceramic heater. The PTC ceramic heater is a resistance type heating body. When electrified, the resistance will increase with the temperature rise, that is, the heating temperature remains constant when the voltage is not constant. In addition, the first cover plate 31 and the second cover plate 32 are constructed of flame-retardant materials, such as fireproof plates or fireproof coatings on the first cover plate 31 and the second cover plate 32, to protect the first cover plate 31 and the second cover plate 32 from being affected by the structure of the first cover plate 31 and the second cover plate 32 due to temperature rise.

[0055] In an additional embodiment of this application, the electric water heater provided in this application embodiment further includes a waterproof plate 4, which is disposed between the heating element 34 and the air outlet 22 to prevent water from splashing from the air outlet 22 onto the heating element 34.

[0056] like Figure 8 As shown, the waterproof plate 4 is an arc-shaped protrusion structure, which is set on the bottom plate of the air-heating module 3, i.e. the second cover plate 32. There is a space between the waterproof plate 4 and the top plate of the air-heating module 3, i.e. the first cover plate 31, so that warm air can flow out.

[0057] like Figure 8 As shown, the bottom plate of the air-heating module 3, namely the second cover plate 32, is tilted downwards towards the air outlet 22 to further promote the outflow of warm air and prevent air blockage and stagnation inside the air-heating module 3.

[0058] In an additional embodiment of this application, such as Figure 9 As shown, the electric water heater provided in this application embodiment also includes an inner tank water inlet 5, which is disposed inside the decorative cover 2 for water to enter and exit.

[0059] Furthermore, such as Figure 10 As shown, the inner tank water nozzle 5 includes a button 6 for controlling the inner tank water nozzle 5, the button 6 including a water inlet button, a water outlet button and a drain button.

[0060] In addition, the electric water heater provided in this application embodiment also has the remote control function of existing electric water heaters. It also has a remote control (not shown), which can be used to start various modes of the electric water heater, making it convenient for users and increasing the ease of use of the electric water heater.

[0061] According to the embodiments of this application, the electric water heater integrates a fan-heating module within the space formed by the decorative cover and the housing by installing a decorative cover at the lower end of the water heater shell. The fan-heating module is embedded in the decorative cover and generates warm air. The air is then delivered through the air outlet and air inlet on the decorative cover. With the above configuration, the electric water heater also has a fan-heating function. At the same time, the size of the electric water heater is not much different from that of the electric water heater before the improvement, and the installation space occupied is small.
