Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown, the utility model provides an electric water heater vertical and horizontal dry-burning tube assembly and an electric water heater thereof, the electric water heater vertical and horizontal dry-burning tube assembly is installed on the flange of the water storage tank, the flange is located below or on the left and right sides of the water storage tank, and includes an electric heating tube seat 401, a dry-burning tube 402, a dry-burning tube fixing plate 403, and a sleeve 407. The sleeve is welded to the electric heating tube seat and has an opening in the electric heating tube seat. The electric heating tube seat is installed on the flange, the sleeve extends into the inner cavity of the water storage tank, the dry-burning tube is inserted into the sleeve and is insulated and separated from the water in the water storage tank by the isolation of the sleeve; the root of the hot water outlet pipe 7 in the water storage tank is close to the electric heating tube seat or passes through the electric heating tube seat, and the top of the hot water outlet pipe extends obliquely upward to the end of the water storage tank away from the flange, so that when the water storage tank is installed vertically or horizontally, the top pipe mouth of the hot water outlet pipe 7 is at the top position of the water storage tank.

[0023] The central axis of the heating tube base coincides with the central axis of the water storage tank. The central axis of the sleeve forms an acute angle A with the central axis of the heating tube base. The sleeve is tilted away from the hot water outlet pipe. A magnesium base bracket 409 is provided inside the water storage tank of the heating tube base 401, and a magnesium rod 406 is mounted on the magnesium base bracket. The magnesium rod 406 is parallel to the sleeve 407. A dry-burning tube fixing bracket is provided on the outside of the heating tube base 401. The dry-burning tube 402 is positioned and installed via a dry-burning tube fixing plate 403, which is secured to the dry-burning tube fixing bracket with fasteners.

[0024] The back of the water heater 1 features four mounting holes 101 for locking plates and a heating tube port 102. The two mounting plates 2 are secured to the mounting holes using four bolt assemblies 3. The heating tube port 102 is positioned vertically at the bottom of the water heater 1. The vertical and horizontal dry-heating tube assembly 4, port sealing ring 5, and five T-bolt assemblies 6 of the present invention are secured to the heating tube port 102.

[0025] The vertical and horizontal dry-heating tube assembly 4 consists of a heating tube base 401, a dry-heating tube 402, a dry-heating tube fixing plate 403, a three-in-one cross hexagonal screw 404, a spring washer 405, a magnesium rod 406, a sleeve 407, and a temperature probe tube 408. The magnesium rod 406 and spring washer 405 are locked to the magnesium base bracket of the heating tube base 401. The two dry-heating tubes 402 are respectively installed in the two sleeves of the heating tube base 401. The dry-heating tube fixing plate 403 and the three-in-one cross hexagonal screw 404 are then used to lock the dry-heating tubes 402. The two dry-heating tubes 402 extend into the two sleeves 407, and the temperature probe tube 408 is inserted into the temperature probe tube 408.

[0026] The water heater 1 can be installed in two ways, vertically or horizontally, through two hanging plates 2, solving the problem of being limited by usage scenarios.

[0027] When the dry-burning tube 402 of the vertical and horizontal dry-burning tube assembly 4 fails and requires after-sales maintenance, the dry-burning tube 402 can be taken out for replacement by simply removing the cross hexagonal three-in-one screw 404 and the dry-burning tube fixing plate 403. The electric heating tube holder 401 seals the electric heating tube tank port 102, and the water in the inner tank will not flow out, and there is no need to drain the water in the inner tank. This is very convenient, achieving the purpose of convenient and fast maintenance of the water heater and saving water resources.

[0028] Working principle: The two hanging plates of the water heater each have two parallel hanging plate holes, so it can be installed vertically or in the bedroom. The vertical and horizontal dry-burning tube components adopt a sleeve method. The sleeve separates the water in the inner tank from the dry-burning tube body, and abnormal dry-burning problems will not occur during operation. It is very convenient to remove the dry-burning tube body, and the sleeve separates the water in the inner tank and will not flow out; the structural design of the electric heating tube seat is designed to be tilted downward, which can solve the problem of increasing the hot water output rate during horizontal installation. The hot water output rate is higher than that of the horizontal dry-burning tube, and it does not affect the vertical installation method.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
