Definitions

  • the present application relates to the technical field of electric water heaters, for example, a non-metal liner and an electric water heater having the same.
  • the liner of an electric water heater serving as a water storage component, is mostly made of metal.
  • a heating pipe also needs to be installed in the liner.
  • a liner flange is usually welded at the liner opening of the metal liner, and then the heating pipe is installed on the heating pipe flange.
  • the liner flange and the heating pipe flange are fixedly connected to achieve the installation of the heating pipe in the metal liner.
  • the liner flange is typically embedded at the liner opening of the non-metal liner through a welding process and then fixedly connected to a heating pipe flange.
  • a fixing member with internal threads is molded in the liner opening of the non-metal liner, and the liner flange, which has external threads, is threadedly connected to the fixing member.
  • the heating pipe flange which holds the heating pipe, is then connected to the liner flange.
  • the disadvantages of this solution lie in the presence of multiple interfaces, such as between the fixing member and the liner flange and between the liner flange and the heating pipe flange.
  • the high number of interfaces increases the likelihood of installation defects and raises the probability of water leakage, thereby affecting the performance of the electric water heater and in severe cases, even posing safety risks.
  • the present application provides a non-metal liner and an electric water heater having the same.
  • a non-metal liner includes a liner body, a reinforcement layer, and a liner flange.
  • One end of the liner body forms a liner opening, and a limiting annular portion surrounding the liner opening is disposed on an outer side of the liner opening.
  • the reinforcement layer covers an outer periphery of the liner body.
  • An inner end of the liner flange is limited and fixed by the limiting annular portion, and an outer end of the liner flange is fixed between the liner body and the reinforcement layer.
  • An electric water heater includes the non-metal liner as described above.
  • connection to each other is to be construed in a broad sense, for example, as securely connected, detachably connected, or integrated; mechanically connected or electrically connected; directly connected to each other or indirectly connected to each other via an intermediary; or internally connected between two elements or interaction relations between two elements.
  • connection detachably connected, or integrated; mechanically connected or electrically connected; directly connected to each other or indirectly connected to each other via an intermediary; or internally connected between two elements or interaction relations between two elements.
  • first feature and the second feature may be in direct contact or be in contact via another feature between the two features instead of being in direct contact.
  • first feature is "on”, “above”, or “over” the second feature
  • first feature is right on, above, or over the second feature, or the first feature is obliquely on, above, or over the second feature, or the first feature is simply at a higher level than the second feature.
  • the first feature When the first feature is “under”, “below”, or “underneath” the second feature, the first feature is right under, below, or underneath the second feature, or the first feature is obliquely under, below, or underneath the second feature, or the first feature is simply at a lower level than the second feature.
  • orientations or position relations indicated by terms such as “above”, “below”, “left”, and “right” are based on orientations or position relations shown in the drawings. These orientations or position relations are intended only to facilitate and simplify the operation and not to indicate or imply that a device or element referred to must have such specific orientations or must be configured or operated in such specific orientations. Thus, these orientations or position relations are not to be construed as limiting the present application.
  • terms “first” and “second” are used only to distinguish between descriptions and have no special meaning.
  • the present application provides a non-metal liner.
  • the non-metal liner is applied to the field of water heaters, such as electric water heaters and is configured to store water.
  • the non-metal liner may be a plastic liner or a liner made of other non-metallic materials.
  • the non-metal liner of the embodiments of the present application includes a liner body 10, a reinforcement layer 20, and a liner flange 30; one end of the liner body 10 forms a liner opening 11, and a limiting annular portion 12 surrounding the liner opening 11 is disposed on an outer side of the liner opening 11; the reinforcement layer 20 covers an outer periphery of the liner body 10; an inner end of the liner flange 30 is limited and fixed by the limiting annular portion 12, and an outer end of the liner flange 30 is fixed between the liner body 10 and the reinforcement layer 20.
  • a limiting annular portion 12 surrounding the liner opening 11 is disposed on the outer side of the liner opening 11, the inner end of the liner flange 30 is limited and fixed by the limiting annular portion 12, and the outer end is fixed between the liner body 10 and the reinforcement layer 20.
  • the liner flange 30 and the liner body 10 can be tightly combined, and no welding point exists, which avoids the leakage at the welded position when the non-metal liner is under high pressure.
  • the liner flange 30 is directly connected to the liner body 10, eliminating the fixing members for fixing the liner flange 30 and reducing the connection interfaces between the fixing members and the liner flange 30, thereby reducing the probability of leakage.
  • the limiting annular portion 12 may be formed integrally with the liner body 10 in the direction from the end of the liner opening 11 away from the center of the liner opening 11. Alternatively, the limiting annular portion 12 may be an independent component set on the outer side of the liner opening 11. The limiting annular portion 12 may be arranged as needed.
  • the liner flange 30 includes an inner end annular portion 31, an outer end annular portion 33, and a protruded connecting portion 32 connected between the inner end annular portion 31 and the outer end annular portion 33, the inner end annular portion 31 is limited and fixed by the limiting annular portion 12, the outer end annular portion 33 is fixed between the liner body 10 and the reinforcement layer 20, and the protruded connecting portion 32 is configured to be connected to a heating pipe flange.
  • the liner flange 30 is configured to include three parts, namely, the inner end annular portion 31, the protruded connecting portion 32, and the outer end annular portion 33 so that the connection between the liner flange 30 and the liner body 10 and between the liner flange 30 and the heating pipe flange is simpler, and the structure of the liner flange 30 is more reasonable.
