The household common water storage type electric water heater is convenient to install, low in price and capable of being used by a user when the household common water storage type electric water heater needs to be heated for a certain time and reaches a certain temperature.

An embodiment of the utility model provides a water heater 100, as shown in fig. 1, this water heater 100 can include water heater organism 1, control box 2, circuit board components 3 and panel 5, and wherein, control box 2 links to each other with water heater organism 1. The circuit board assembly 3 may include a circuit board 31 and electrical components such as spring buttons 32, soldered relays and terminals soldered thereto. The elastic button 32 is located on the side of the circuit board 31 away from the water heater body 1. The elastic key 32 has a first end a and a second end b opposite to each other, and the first end a is electrically connected to the circuit board 31. As shown in fig. 2, the control box 2 has a mounting cavity 21, the circuit board assembly 3 is mounted in the mounting cavity 21, and a plurality of through openings 22 are opened on one side of the control box 2, which is located on the elastic key 32 and away from the circuit board 31. As shown in fig. 3, the water heater 100 may further include a shape-changing plate 4, the shape-changing plate 4 is disposed at the opening 22 and connected to an edge of the opening 22, in one opening 22, a gap 41 is formed on the shape-changing plate 4, and the second end b of the elastic key 32 abuts against the shape-changing plate 4. The panel 5 is attached to the outer surface of the control box 2 on the side where the opening 22 is formed.

In this case, as shown in fig. 1 to 4, the water heater body 1 is used for containing and heating water. Control box 2 links to each other with water heater organism 1, set up the opening 22 that runs through on control box 2, this opening 22 department can set up shape deformation piece 4, and link to each other with opening 22's edge, the second end b of elasticity button 32 can the butt on shape deformation piece 4, when the external force that the user applyed is on panel 5, thereby panel 5 produces deformation and makes shape deformation piece 4 begin to produce deformation extrusion elasticity button 32 second end b, because the first end a and the circuit board 31 electricity of elasticity button 32 are connected, consequently, receive the circuit on extruded elasticity button 32 can the trigger circuit board 31. Because the deformation sheet 4 separates the elastic keys 32 from the panel 5, the panel 5 is not directly contacted with the elastic keys 32, and the panel 5 is prevented from being directly stressed by the elastic keys 32. Therefore, the stress of the elastic keys 32 on the panel 5 is improved, and the phenomena of warping and loosening of the panel 5 are reduced. In addition, because the deformation sheet 4 is provided with the gap 41, a deformation space is formed when the deformation sheet 4 deforms, and the deformation sheet 4 can quickly generate deformation to trigger the elastic key 32.

The gap 41 mentioned above is exemplified below, for example, as shown in fig. 3, in some embodiments of the present application, the shape of the gap 41 may be an ellipse, as shown in fig. 4, the gap 41 may be a straight line, and in other embodiments of the present application, the gap 41 may also be a polygon.

And the mounting cavity 21 of the control box 2 may share a portion with the water heater body 1. If the control box 2 adopts a sealed shell, not only the material for manufacturing the control box 2 is wasted, but also the control box 2 is inconvenient to install on the water heater body 1. However, since the water heater body 1 contains water, in order to prevent water leakage from the water heater body 1 from falling into the installation cavity 21, in some embodiments of the present application, as shown in fig. 10, the water heater 100 may further include a baffle 26 covering the installation opening 25, and the baffle 26 may have a certain curved surface matching with the outer surface of the water heater body 1.
