Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to an electric water heater. Background Technology

[0002] A foaming cavity is formed between the inner tank and the outer shell of the water heater. It is used to fill the foaming material to form a foam layer and insulate the inner tank. A baffle is installed inside the outer shell. The side of the baffle away from the foaming cavity is used to install electrical components. The baffle separates the foaming material from the components to prevent the foaming material from affecting the operation of the components.

[0003] To prevent the baffle from deforming under stress during the foaming process, the baffle is usually designed to have a certain thickness to ensure its structural strength. Therefore, the baffle has a thick wall, which increases its weight, increases its cost, and is not conducive to the lightweight design of the entire water heater. In addition, the connection between the baffle and the outer shell usually relies on interference fit or fastener fixation, which results in low connection stability, difficulty in positioning during the fixing process, and high assembly difficulty and low efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide an electric water heater that solves the problems of existing water heaters having thick baffles, high cost, heavy weight, difficulty in fixing the baffles to the outer shell, and low assembly efficiency.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] This utility model discloses an electric water heater, which includes:

[0007] The outer casing has an internal mounting cavity formed therein;

[0008] An inner liner is disposed in the mounting cavity, and a heating cavity is formed within the inner liner.

[0009] A baffle is disposed in the mounting cavity and connected to one end of the inner liner;

[0010] The baffle has a reinforcing outer edge formed on its periphery, and the reinforcing outer edge extends toward the inner liner.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are:

[0012] The baffle component involved in this application has a reinforcing outer edge extending towards the inner tank component on its periphery. The design of the reinforcing outer edge has two advantages: first, it can increase the structural strength of the baffle component and reduce its deformation after being subjected to foaming force; second, it can also reduce the wall thickness of the baffle component, save production costs, and reduce the weight of the baffle component, which is conducive to the lightweight improvement of water heaters; in addition, the reinforcing outer edge can also increase the contact area with the outer shell, facilitate the installation and positioning of the baffle component in the outer shell, and improve the connection stability of the baffle component.

[0013] In some embodiments of this application, the side of the baffle closer to the inner liner is a first end face, and the side away from the inner liner is a second end face, and a reinforcing rib is formed on the first end face of the baffle.

[0014] The design of the reinforcing ribs can further improve the structural strength of the baffle itself, reduce its deformation after being subjected to the foaming material, and help reduce its thickness while ensuring its structural strength, thus reducing its weight.

[0015] In some embodiments of this application, the baffle has a connection port, one end of the inner liner is connected to the connection port, and the reinforcing ribs are distributed in a radiating pattern around the connection port.

[0016] The reinforcing ribs are distributed in a radiating pattern around the connection, which makes the distribution of the reinforcing ribs on the baffle more uniform and improves the strength of the baffle.

[0017] In some embodiments of this application, a positioning recess is formed on the outer side of the reinforcing outer edge, and a positioning protrusion corresponding to the position of the positioning recess is formed on the inner wall of the outer shell, and the positioning recess is connected to the positioning recess.

[0018] The combination of the positioning recess and the positioning protrusion can achieve the initial positioning of the baffle and the outer shell. After being subjected to the foaming material, it can also play an auxiliary positioning role. In addition, it can improve the sealing effect of the connection between the baffle and the outer shell, and prevent the foaming material from overflowing from the gap between the baffle and the outer shell to the other side of the baffle, thus improving safety.

[0019] In some embodiments of this application, a plurality of reinforcing uprights are also provided at intervals within the positioning recess to improve the structural strength of the reinforcing outer edge, wherein the height of the reinforcing uprights is less than the depth of the positioning recess.

[0020] The reinforcing upright can improve the structural strength of the reinforcing outer edge. The height of the reinforcing upright is less than the depth of the positioning recess to ensure that the positioning protrusion can at least partially connect to the positioning recess, thus ensuring the connection and sealing effect.

[0021] In some embodiments of this application, the outer casing includes a first housing and a second housing, and at least one first connecting portion is formed on the reinforcing outer edge, the first connecting portion being detachably connected to the first housing by fasteners; and / or

[0022] At least one second connecting portion is formed on the reinforcing outer edge, and the second connecting portion is detachably connected to the second housing by fasteners.

[0023] The first and second connecting parts can further connect and fix the baffle and the outer casing.

[0024] In some embodiments of this application, a first support protrusion extending toward the inner liner is further formed on the first end face, and a first conformal surface adapted to the end shape of the inner liner is formed on the first support protrusion, and the first conformal surface is in contact with the end of the inner liner.

[0025] The first support protrusion provides support for the inner liner, and the first conformal surface contacts the end of the inner liner to improve the stability of the support.

[0026] In some embodiments of this application, the outer casing includes a first housing and a second housing. The first housing includes a front wall and a side wall formed on the periphery of the front wall. The number of the first support protrusions is two, which are circumferentially spaced along the connection port on the side close to the front wall.

[0027] The inner liner is installed into the first housing from the opening towards the front wall. The first support protrusion is located on the side near the front wall, which ensures that the inner liner is installed smoothly into the first housing and avoids interference during installation.

[0028] In some embodiments of this application, the inner liner includes a side cylinder wall, and a second support protrusion is provided on the inner wall of the second housing. A second conformal surface adapted to the side cylinder wall is formed on the second support protrusion, and the second conformal surface is in contact with the side cylinder wall.

[0029] The second support protrusion cooperates with the first support protrusion to support the inner liner and ensure the stability of the inner liner in the installation cavity.

[0030] In some embodiments of this application, the axis of the inner liner is arranged along the horizontal direction, and the second support protrusion is located below the horizontal plane passing through the axis of the inner liner.

[0031] The second support protrusion provides upward support to the inner liner, which helps to distribute the weight of the inner liner and makes the support effect more stable.

[0052] An electric water heater is a type of water heater that uses electricity as its primary energy source. The high-temperature heat generated after the power is turned on directly heats the water stored in the water heater to produce hot water.

[0053] Electric water heaters typically consist of a water tank, an electric heating element, and an electronic control board. The water tank has a storage cavity to store water to be heated. The electric heating element is inserted into the storage cavity of the water tank. The electronic control board is used to control the electric heating element to operate by turning the power on and off, so that the water in the tank is heated to the set temperature.

[0054] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank, with an insulation layer between them. The outer shell is usually made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank can be made of metal or plastic, depending on the needs.

[0055] In addition, the insulation layer formed between the outer shell and the inner liner is commonly made of materials such as asbestos, sponge, foam plastic, and polyurethane foam. In conventional technology, foaming is usually used to form the insulation layer in order to achieve good insulation effect.

[0056] For water tanks with metal inner liner, corrosion can easily occur inside due to water quality. Therefore, magnesium rods are installed on the water tank and inserted into the water storage cavity inside the tank.

[0057] Magnesium has the lowest electrochemical potential among metals and is physiologically non-toxic. Therefore, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod directly affects the duration and effectiveness of the protection; the larger the magnesium rod, the better the protection and the longer the protection time.

[0058] The water tank is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver cold water into the water storage cavity formed inside the water tank, while the hot water in the water storage cavity is output from the outlet pipe.

[0059] For electric heating components, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be used to heat the water stored in the water storage chamber.

[0060] The control board is used to receive detection signals from relevant sensors (such as water temperature sensors and flow sensors) and control the power supply to and from the electric heating components.

[0061] When the electric water heater is working, the electric control board controls the electric heating element to be powered on and heated. When the water temperature in the tank reaches the set value, the electric control board controls the electric heating element to be powered off.

[0062] This utility model proposes an electric water heater, which includes an outer shell 100, an inner tank 200, and a baffle 300, wherein an installation cavity is formed inside the outer shell 100.

[0063] An installation cavity is formed inside the outer shell 100, and an inner liner 200 is disposed in the installation cavity. A heating cavity is formed inside the inner liner 200.

[0064] The baffle 300 is disposed in the mounting cavity and connected to one end of the inner liner 200. The side of the baffle 300 facing away from the inner liner 200 is used to install components.

[0065] At least one end of the housing 100 is provided with an end cover (not shown). The end cover is detachably connected to the housing 100. Specifically, the end cover is located at the end near the stop member 300, which is used to facilitate the installation, maintenance and repair of components and working parts such as heating elements.

[0066] A foaming cavity is formed between the outer shell 100, the inner liner 200, and the baffle 300. Foaming material is filled into the foaming cavity to form a foam layer for heat preservation of the inner liner 200. The foaming pressure of the foaming material is high. During the foaming process, the foaming material is prone to overflowing from one side of the baffle 300 to the other side. Furthermore, due to the influence of the foaming pressure, the baffle 300 may deform or shift in position.

[0067] To solve the above problems, the retaining member 300 involved in this application has a reinforcing outer edge 320 formed on its periphery, and the reinforcing outer edge 320 extends toward the inner liner member 200.

[0068] Strengthening the outer edge 320 has two main benefits: firstly, it increases the structural strength of the retaining component 300, reducing its deformation under foaming forces; secondly, it reduces the wall thickness of the retaining component 300, saving production costs and reducing its weight, which is beneficial for the lightweight improvement of the water heater; in addition, strengthening the outer edge 320 can increase the contact area with the outer casing 100, facilitating the installation and positioning of the retaining component 300 within the outer casing 100 and improving the connection stability of the retaining component 300.

[0069] The outer casing 100 involved in this application includes a first casing 110 and a second casing 120. The first casing 110 includes a front wall 111 and a side wall 112 formed on the periphery of the front wall 111. The second casing 120 is connected to the side wall 112 of the first casing 110. An assembly opening 114 is formed on the first casing 110, and an end cap is detachably connected to the assembly opening 114.

[0070] The front wall 111 and the side wall 112 are integrally formed by injection molding. The second shell 120 is also integrally formed by injection molding. The first shell 110 and the second shell 120 are assembled into the entire outer shell 100 after processing.

[0071] A first fixing part 117 is provided on the inner side of the first housing 110. The first fixing parts 117 are spaced apart along the periphery of the first housing 110, and each first fixing part 117 has a threaded hole with an opening facing the second housing 120.

[0072] In other words, the first fixing part 117 is formed on the inner side of the side wall 112.

[0073] The inner wall of the second housing 120 is provided with a second fixing part 122 that corresponds one-to-one with the first fixing part 117, and a through connecting hole is formed on the second fixing part 122.

[0074] During installation, fastening screws from the outer side of the second housing 120 are connected to the second fixing part 122 and the corresponding first fixing part 117, thereby achieving a detachable connection between the first fixing part 117 and the second fixing part 122.

[0075] The water heater involved in this application is horizontal, and the front wall 111 of the first housing 110 is located on the front side of the water heater. It is equipped with an operation panel or adjustment knob 130 and other control structures to control the water heater switch and / or adjust the heating water temperature.

[0076] The second housing 120 is located at the rear of the water heater and has a mounting part for mounting on the user's front wall 111.

[0077] In some embodiments of this application, the side of the baffle 300 closest to the inner liner 200 is a first end face, and the side away from the inner liner 200 is a second end face. A reinforcing rib 330 is formed on the first end face of the baffle 300.

[0078] The design of the reinforcing rib 330 can further improve the structural strength of the baffle 300 itself, reduce its deformation after being subjected to the foaming material, and help to reduce its thickness while ensuring its structural strength, which is conducive to reducing weight.

[0079] In some embodiments of this application, a connection port 310 is formed on the baffle 300, one end of the inner liner 200 is connected to the connection port 310, and a support ring is provided on the side of the connection port 310 near the inner liner 200.

[0080] The inner liner 200 specifically includes a side cylinder wall 220 and hemispherical end walls 210 formed at both ends of the side cylinder wall 220. The side end wall 210 near the baffle 300 abuts against the support ring. An installation port 211 is formed on the end wall 210, and the installation port 211 is aligned with the connection port 310.

[0081] The electric heating element, magnesium rod, etc. extend through the connection port 310 and the mounting port 211 into the heating cavity of the inner liner 200. The electric heating element is used to heat the liquid in the heating cavity, and the magnesium rod is used to prevent oxidation of the inner wall of the inner liner 200.

[0082] In some embodiments of this application, the reinforcing ribs 330 are distributed in a radiating pattern around the connection port 310, which makes the distribution of the reinforcing ribs 330 on the baffle 300 more uniform and the strength of the baffle 300 better.

[0083] In some embodiments of this application, a positioning recess 321 is formed on the outer side of the reinforcing outer edge 320, and a positioning protrusion 113 corresponding to the position of the positioning recess 321 is formed on the inner wall of the outer shell 100, and the positioning protrusion 113 is connected to the positioning recess 321.

[0084] Specifically, the positioning protrusion 113 is formed on the inner wall of the first housing 110. Initially, the stop member 300 moves from the opening position of the first housing 110 toward the front wall 111 of the first housing 110 for assembly. The positioning protrusion 113 corresponds to the positioning recess 321, which facilitates the positioning of the stop member 300 and helps to improve the accuracy of assembly.

[0085] In other words, the cooperation between the positioning recess 321 and the positioning protrusion 113 can achieve the initial positioning of the baffle 300 and the outer shell 100. After being subjected to the foaming material, it can also play an auxiliary positioning role. In addition, the positioning protrusion 113 inserted into the positioning recess 321 can also improve the sealing effect of the connection between the baffle 300 and the outer shell 100, preventing the foaming material from overflowing from the gap between the baffle 300 and the outer shell 100 to the other side of the baffle 300, thus improving safety.

[0086] In some embodiments of this application, a plurality of reinforcing uprights 322 are also provided at intervals within the positioning recess 321 to improve the structural strength of the reinforcing outer edge 320, and the height of the reinforcing uprights 322 is less than the depth of the positioning recess 321.

[0087] The reinforcing upright 322 can improve the structural strength of the reinforcing outer edge 320. The height of the reinforcing upright 322 is less than the depth of the positioning recess 321 to ensure that the positioning protrusion 113 can be at least partially connected to the positioning recess 321, thus ensuring the connection and sealing effect.

[0088] The height of the reinforcing upright 322 in the positioning recess 321 that is not connected to the positioning protrusion 113 can be the same as the depth of the positioning recess 321, that is, the top of the reinforcing upright 322 is flush with the outer wall of the reinforcing upright 322.

[0089] In addition to being connected to the housing 100 via the positioning recess 321, the stop member 300 is further connected and fixed to the housing 100 via fasteners such as fastening screws.

[0090] Specifically, at least one first connecting portion 350 is formed on the reinforcing outer edge 320, and the first connecting portion 350 is detachably connected to the first housing 110 by fasteners.

[0091] For example, but not limited to, two first connecting portions 350 are provided at intervals on the side of the reinforcing outer edge 320 near the front wall 111 of the first housing 110. The first connecting portions 350 have connecting holes. Correspondingly, a connecting protrusion 115 extending into the inner cavity is formed on the front wall 111 of the first housing 110. The connecting protrusion 115 has a threaded hole. The threaded hole is non-through to maintain the integrity of the front wall 111 of the first housing 110 and improve the aesthetics and sealing effect.

[0092] During assembly, after the stop part 300 is assembled into the first housing 110, the operator passes the fastening screw through the connecting hole and connects it to the threaded hole of the corresponding connecting protrusion 115 to achieve the connection and fixation between the first connecting part 350 and the first housing 110.

[0093] In other embodiments, at least one second connection portion 360 is formed on the reinforcing outer edge 320, and the second connection portion 360 is detachably connected to the second housing 120 by fasteners.

[0094] For example, but not limited to, two second connecting portions 360 are provided at intervals on the side of the reinforcing outer edge 320 near the second housing 120. The second connecting portions 360 have threaded holes, and the corresponding second housing 120 has through connecting holes. After the baffle 300 is initially connected and fixed to the first housing 110, the second housing 120 is placed on the rear side of the first housing 110, and fastening screws are passed through the connecting holes on the corresponding second housing 120 and connected to the second connecting portions 360 to achieve the connection and fixation of the baffle 300 and the second housing 120.

[0095] In order to improve the structural strength of the first housing 110, a plurality of inner reinforcing ribs 118 extending along the direction close to the front wall 111 are provided at intervals on the inner side of the side wall 112 of the first housing 110.

[0096] In some other embodiments, a first support protrusion 340 extending toward the inner liner 200 is also formed on the first end face. A first conformal surface adapted to the end shape of the inner liner 200 is formed on the first support protrusion 340. The first conformal surface is in contact with the end of the inner liner 200.

[0097] The first support protrusion 340 is located on the side of the baffle 300 near the front wall 111 of the first housing 110. The first support protrusion 340 is used to provide support for the inner liner 200. The first conformal surface contacts the end of the inner liner 200 to improve the stability of the support.

[0098] For example, but not limited to, the number of first support protrusions 340 is two, which are arranged circumferentially along the connection port 310 on one side near the front wall 111.

[0099] The inner liner 200 is installed into the first housing 110 from the opening position of the first housing 110 toward the front wall 111. The first support protrusion 340 is located on the side near the front wall 111, which can ensure that the inner liner 200 is smoothly installed into the first housing 110, avoid interference during installation, and ensure that the inner liner 200 moves toward the front wall 111 of the first housing 110 for assembly.

[0100] In some embodiments of this application, a second support protrusion 121 is provided on the inner wall of the second housing 120. The second support protrusion 121 extends toward the mounting cavity. In order to reduce the weight of the second housing 120 and provide sufficient contact for the inner liner 200, the second support protrusion 121 is designed as a housing structure. Furthermore, the second support is designed as a non-linear shape such as a U-shape or an S-shape to increase the contact area between the second support protrusion 121 and the inner liner 200.

[0101] The second support protrusion 121 has a second conformal surface that is adapted to the side cylinder wall 220, and the second conformal surface is in contact with the side cylinder wall 220.

[0102] The second support protrusion 121 cooperates with the first support protrusion 340 to support the inner liner 200 and ensure the stability of the inner liner 200 in the installation cavity.

[0103] In some embodiments of this application, the axis of the inner liner 200 is arranged along the horizontal direction, and the second support protrusion 121 is located below the horizontal plane passing through the axis of the inner liner 200.

[0104] The second support protrusion 121 provides upward support to the inner liner 200, which helps to distribute the weight of the inner liner 200 and makes the support effect more stable.

[0105] In some other embodiments, the second end face of the baffle 300 is provided with a first mounting position 301, a second mounting position 302 and a third mounting position 303. The first mounting position 301 has a wire passage groove for wire harness to pass through, the second mounting position 302 is used to fix the temperature controller and the third mounting position 303 is used to fix the circuit board.

[0106] In other embodiments, the electric water heater of this application adjusts the heating water temperature and controls the switch by adjusting the knob 130. The end of the baffle 300 near the front wall 111 is formed with a relief recess 370 extending toward the inner tank 200. The rear end of the adjusting knob 130 is installed in the relief recess 370.

[0107] In other words, the clearance recess 370 is a groove formed on the second end face of the stop member 300 and extending toward the first end face, which provides installation space for the adjustment knob 130.

[0108] Correspondingly, a through hole 116 is formed on the front wall 111 of the first housing 110, and the front end of the adjustment knob 130 extends from the through hole 116 to the outside of the electric water heater for easy operation by the user.
