A sliding plug-in variable capacity energy-saving water heater

Abstract

The invention discloses a sliding plug-in type energy-saving type water heater with a variable capacity. The sliding plug-in type energy-saving type water heater comprises a main box body and a secondary box body, wherein each of the main box body and the secondary box body comprises a shell body and a liner; a heat insulation layer is arranged between each shell body and each liner; the lower part of the liner of the main box body is communicated with a water inlet pipe and a water outlet pipe; the water inlet pipe is communicated with an exhausting valve; a heating tube and a detection rod of a temperature controller are fixed in the liner and a bent separation plate is further fixed in the liner; the bent separation plate is used for dividing a cavity of the liner into a cold cavity and a hot cavity; the water outlet pipe is communicated with the hot cavity and the water inlet pipe is communicated with the cold cavity; a sliding block is fixed at the bottom of the shell body of the secondary box body and is inserted into a transverse slide rail; a supporting frame is fixed at the bottom of the transverse slide rail and is fixed on a wall body. The sliding plug-in type energy-saving type water heater can heat rapidly and also can meet the requirements of different users by increasing and decreasing the capacity according to the needs.

Description

[0001] Technical field: [0002] The invention relates to the technical field of water heaters, in particular to a sliding plug-in energy-saving water heater with variable capacity. [0003] Background technique: [0004] When the water tank of the existing water heater is heated by electricity, the whole water tank is heated, and the cold water and the superheated hot water are mixed in one space volume. Because of the large water storage capacity, it takes a long time to heat the water in the whole water tank, and the water temperature is difficult to increase quickly. High power consumption; [0005] Moreover, the volume of existing water heaters is fixed, which cannot be increased or decreased according to needs, so that it cannot be changed according to the needs of users. Generally, some people will buy water heaters with larger volumes, but for some people who only need a small amount of hot water to use waste is generated.
