Problems solved by technology
Although this heating method can provide a better heating effect, it has the disadvantages of being difficult to process and inconvenient to install. Especially when the inner wall of the inner tank is coated with enamel material, this installation method of central heating will affect the inner tank. The surface structure of the enamel has a destructive effect, because the copper coil is a penetrating connection structure on the inner tank, in order to prevent water from seeping out, it is necessary to fasten and seal the connection structure between the copper coil and the inner tank, so, The enamel surface near the inlet and outlet of the copper coil tube of the liner with this structure is easily cracked and damaged, thus losing its proper anti-corrosion protection function
The above defects have greatly limited the further popularization and application of air energy heat pump water heaters

Embodiment Construction
[0021] refer to Figure 1 to Figure 3 , a kind of undermount heating water heater of the present invention, comprises shell 1 and liner 2, and liner 2 comprises barrel body 21, top cover 22 and bottom cover 23, and barrel body 21, top cover 22 and bottom cover 23 are fastened and sealed connection Finally, an inner cavity 24 is formed, and a copper coil 3 is arranged in the inner cavity 24. The heat transfer medium flows in the copper coil 3, and a pressure plate 4 is arranged below the inner cavity 24, and the pressure plate 4 is tightly connected to the bottom cover 23 through the flange 5. Then, the pressure plate 4 is provided with copper coil pipe inlet and outlet 41, 42, and the copper coil pipe 3 is connected with the copper pipe 6 located outside the inner tank 2 through the copper coil pipe inlet and outlet 41, 42. In actual application, the barrel body 21, the top cover 22 and the bottom cover 23 are generally welded to form an integral structure of the inner tank 2,...

The invention discloses an underneath type heating water heater, which comprises a shell and a liner, wherein the liner comprises a barrel body, a top cover and a bottom cover; a copper coil pipe is arranged in the liner; a heat transfer working substance flows in the copper coil pipe; a pressure plate is arranged below the liner and is tightly connected with the bottom cover through a flange; the pressure plate is provided with a copper coil pipe inlet and a copper coil pipe outlet; and the copper coil pipe is connected with a copper pipe arranged outside the liner through the copper coil pipe inlet and the copper coil pipe outlet. The whole copper coil pipe of the water heater is arranged on the lower part of the liner and is connected with the copper pipe outside the liner through the copper coil pipe inlet and the copper coil pipe outlet on the pressure plate below the liner, and the water heater adopting the structure is convenient to mount and has a compact structure; when the inner wall of the liner of the water heater is coated with an enamel material, the structure cannot generate damages to the enamel surface of the liner; and because the pressure plate is tightly connected with the bottom cover of the liner through the flange, the joint between the liner and the pressure plate has good enough leak tightness, and the seepage problem caused by the adoption of the underneath type heating structure is avoided.
Description
technical field [0001] The invention relates to a water heater, in particular to a bottom-mounted heating water heater with an improved structure. Background technique [0002] Compared with traditional electric water heaters, gas water heaters, and solar water heaters, air energy heat pump water heaters have the characteristics of energy saving, high efficiency, and safety. Therefore, air energy heat pump water heaters will be chosen and loved by more and more users. [0003] Existing air energy heat pump water heaters generally adopt the form of central heating, that is, the copper coil is arranged in the middle of the inner tank, and its inlet and outlet pass through the side wall of the inner tank. Although this heating method can provide a better heating effect, it has the disadvantages of being difficult to process and inconvenient to install. Especially when the inner wall of the inner tank is coated with enamel material, this installation method of central heating wi...
