[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] To address the technical problem in related technologies where bathrooms or shower rooms are often small, placing water heaters and bathroom heaters or warm air blowers within this limited space reduces the user's activity space, causing inconvenience and impacting the user experience, this application provides an electric water heater equipped with a warm air device. This device heats the air in the fan housing and vents warm air through the outlet, improving the indoor environment and enhancing the user experience. The water heater in this application is a multi-functional electric water heater with a compact warm air device that does not take up excessive space, thus meeting user needs.

[0039] In some exemplary embodiments, such as Figures 1-8As shown, an electric water heater includes a water tank 1. The water tank 1 can be three-dimensional, cylindrical, or irregularly shaped, and its capacity can be 60L, 100L, etc., depending on the actual situation.

[0040] The electric water heater includes a heating device 2 installed in the water tank 1 to change the indoor temperature, meet the user's needs, and improve the user experience.

[0041] The heating device 2 includes a blower box 21, a heating unit 25, a fan assembly 22, and a shock-absorbing bracket 23. The blower box 21 has an air inlet 2121 and an air outlet 2131.

[0042] The fan assembly 22 is connected to the air box 21 through the air inlet 2121, delivering external cold air into the air box 21. The anti-vibration bracket 23 is installed on the fan assembly 22, and the heating unit 25 is set inside the air box 21 to heat the cold air into warm air. The heating unit 25 is close to the air outlet 2131, so that the warm air can be sent out through the air outlet 2131.

[0043] Among them, the fan assembly 22 includes, for example, a fan 221 and an air supply duct 222. The fan 221 is connected to the air box 21 through the air supply duct 222. The fan 221 sends external cold air into the air supply duct 222 and into the air box 21 through the air supply duct 222.

[0044] In some examples, such as Figures 3-5 As shown, fan 221 is an axial fan. Axial fans are small in size and have higher air pressure, which can improve air delivery efficiency.

[0045] The anti-vibration bracket 23 includes a first clamping part 231 and a second clamping part 232. The axial fan is clamped between the first clamping part 231 and the second clamping part 232 to fix the axial fan, improve the stability of the axial fan, and prevent it from shaking or misaligning.

[0046] The first clamping part 231 includes an arched body 2311 and two connecting ears 2312, which are disposed on both sides of the arched body 2311 and fixedly connected. The second clamping part 232 is provided with a recessed groove 2321 and two connecting supports 2322, which are disposed on both sides of the recessed groove 2321. The air supply duct 222 abuts against the arched body 2311 and the recessed groove 2321 in its radial direction, and the connecting ears 2312 and the connecting supports 2322 are connected one by one and bolted together with bolts 233.

[0047] When the first clamping part 231 and the second clamping part 232 are engaged, they can be inserted into the air inlet 2121. To improve stability, a collar 234 can be provided for fixation. The collar 234 is fitted onto the first clamping part 231 and the second clamping part 232. The collar 234 has a lug 2341, which is connected to the side of the bellows 21 by a screw or bolt passing through the lug 2341, making the connection between the shock-absorbing bracket 23 and the bellows 21 more reliable. The bellows 21 has a long sidewall and a short sidewall, with the air inlet 2121 located on the short sidewall.

[0048] The shock-absorbing bracket 23 may be made of soft silicone material, that is, the first clamping part 231 and the second clamping part 232 may be made of soft silicone material to achieve the shock-absorbing effect. Alternatively, the first clamping part 231 and the second clamping part 232 may be made of plastic or hard material, with soft silicone material attached inside to achieve the shock-absorbing effect, depending on the actual situation.

[0049] In other examples, such as Figures 6-8 As shown, fan 221 is a centrifugal fan. Centrifugal fans are slightly larger in size and can achieve reversible airflow, enabling fan 221 to be versatile and meet various air supply needs.

[0050] The anti-vibration bracket 23 includes an anti-vibration pad 235, which supports the centrifugal fan. The anti-vibration pad 235 can be attached to the centrifugal fan and the cover 24 respectively. The cover 24 will be described in detail later. It reduces the vibration of the centrifugal fan, improves the stability of the centrifugal fan, avoids noise caused by vibration, and improves the user experience.

[0051] A centrifugal fan is inserted into one end of the air supply duct 222, which is a flat cylindrical shape. The other end of the air supply duct 222 is inserted into the air inlet 2121. The air inlet 2121 can be located on the long side wall of the air box 21.

[0052] In this embodiment, as Figures 4-8 As shown, the bellows 21 includes a bellows cover 211, an upper bellows 212, and a lower bellows 213. The upper bellows 212 is rectangular, with openings on both the upper and lower sides. The bellows cover 211 is fastened to the upper bellows 212 to close the upper opening of the upper bellows 212. An air inlet 2121 is located on the side of the upper bellows 212 to supply air into the upper bellows 212.

[0053] The upper air box 212 is connected to the lower air box 213, which shields the lower side of the upper air box 212. The upper side of the lower air box 213 is open to receive warm or cold air from the upper air box 212. A heating unit 25 is installed inside the lower air box 213, close to the upper air box 212, to heat the air inside the upper air box 212 and generate warm air. The heating unit 25 is, for example, a heater, which consists of multiple heating elements connected in sequence. There is a gap between each pair of adjacent heating elements to allow air to pass through the heater and enter the lower air box 213. The air passing through the heater increases the contact area between the air and the heater, improving heating efficiency, accelerating temperature rise, and meeting user needs.

[0054] The air outlet 2131 is located at the lower part of the lower air box 213 to facilitate the delivery of warm air. The air outlet 2131 can be equipped with louvers, which are set at an angle relative to the air outlet 2131 to block the air outlet 2131. This ensures that warm air can be output while preventing external water from entering the lower air box 213, thus protecting the interior.

[0055] In this embodiment, as Figures 2-4 , Figure 6 , Figure 8 As shown, the heating device 2 also includes a cover 24, which covers the air box 21 to protect the air box 21 and the shock-absorbing bracket 23, and to ensure a clean appearance. The cover 24 is connected to the water tank 1, achieving an integrated design, meeting the diverse functions of the electric water heater, and improving the user experience. The cover 24 can be fixed to the water tank 1, for example, by bolts, screws, or clips, improving the reliability of the connection between the cover 24 and the water tank 1, and achieving assembly connection.

[0056] The cover 24 is also provided with a cover air outlet 241, which corresponds to the air outlet 2131 in the heating device 2, so as to ensure that the warm air can be delivered to the outside, such as the bathroom or shower room.

[0057] In this embodiment, as Figure 5 , Figure 8 , Figure 9 As shown, the electric water heater also includes a control system 3, which includes a control unit 31, a display unit 32, and a switch unit 33.

[0058] The control unit 31 is connected to the display unit 32 and the switch unit 33. The switch unit 33 is used to control the electric water heater and / or the heating device 2.

[0059] The control unit 31, for example, is a computing and storage module that can receive, store and process data, and issue instructions to control the electric water heater, thereby realizing intelligent and automated control of the electric water heater.

[0060] Display unit 32 may include a display operation module and a display screen. The display screen can display, but is not limited to, data such as temperature and wind speed. The temperature may be water temperature or air temperature. The display screen has an embedded display operation module, allowing users to control the electric water heater via touch and select corresponding functions.

[0061] The switching unit 33 includes, for example, a first relay 331, a second relay 332 and a third relay 333. The first relay 331 is located in the temperature regulating device and is used to control the on and off of the temperature regulating device to heat the water tank 1.

[0062] The water tank 1 is equipped with a water flow sensor 36, which is electrically connected to the control unit 31 to monitor the water flow.

[0063] The second relay 332 is installed in the fan 221, for example, to control the on / off state of the fan 221.

[0064] The third relay 333 is, for example, installed in the heating unit 25 to control the on / off state of the heating unit 25.

[0065] In this embodiment, as Figure 5 , Figure 8 , Figure 9 As shown, the control system 3 also includes a detection element 34, which is used to detect the electric water heater and / or the heating device 2 to achieve intelligent monitoring.

[0066] The detection components 34 include, for example, a water tank temperature module 341, an outlet air temperature module 342, and an inlet air temperature module 343. The water tank temperature module 341 is installed inside the water tank 1 to monitor the water temperature. The outlet air temperature module 342 is installed at the air outlet 2131 to monitor the outlet air temperature, and the inlet air temperature module 343 is installed at the air inlet 2121 to monitor the inlet air temperature.

[0067] Detection component 34, for example, is a sensor, to achieve intelligent monitoring, which is low-cost and will not significantly increase the cost of the electric water heater.

[0068] The control system 3 may also include a remote access module 35, which wirelessly connects to the display unit 32, detection element 34, etc., to achieve communication connectivity with the electric water heater. The remote access module 35 may be, for example, but is not limited to, infrared connection, radio wave connection, Bluetooth connection, or Wi-Fi connection.

[0069] The electric water heater proposed in this application is equipped with a heating element that heats the air in the fan housing and vents warm air through the outlet, improving the indoor environment and enhancing the user experience.
