Problems solved by technology

This solution has the following disadvantages: first, the action process is too complicated, the user's manual operation is easy to be confused, the feasibility is low, and the user experience is poor; second, it needs to waste a lot of energy in the volume changing operation; third, the system has volume changing If the water inlet pressure is not consistent with the inner tank pressure of the water heater, the inner tank pressure is too small. When the system water inlet is opened, due to the pressure difference, the actual water volume in the inner tank is much greater than the set value, and the control is unreliable.

Embodiment 1

[0054] A kind of electric water heater 1, as figure 1 , figure 2 , image 3 As shown, the electric water heater 1 may include: an inner tank 11 and a heating device 12 disposed in the inner tank 11 , and also includes: a water inlet and outlet control unit 13 and a microcontroller 14 disposed outside the inner tank 11 ;

[0055] The microcontroller 14 is used to control the water in and out control unit 13 according to different heating modes, so as to realize variable volume heating; wherein the heating modes include: the whole tank heating mode and the half tank heating mode;

[0056] The water inlet and outlet control unit 13 is used to automatically control the water inlet and / or outlet of the inner tank 11 according to the control instructions of the microcontroller 14 .

[0057] In the embodiment of the present invention, the heating device 12 mainly realizes the heating function of the electric water heater. For example), the reliable operation of the variable capac...

Embodiment 2

[0059] This embodiment introduces the composition and structure of the water inflow and outflow control unit 13 in detail on the basis of the first embodiment.

[0060] Optionally, as in figure 2 , image 3 As shown, the water inlet and outlet control unit 13 may include: a sewage discharge assembly 131, a water inlet assembly 132 and a water outlet assembly 133;

[0061] The sewage discharge assembly 131 is used to discharge the sewage in the inner tank 11, and is used to discharge the excess water in the inner tank 11 when the electric water heater 1 is converted from the whole tank heating mode to the half tank heating mode, and to control the heating water level of the half tank ;

[0062] The water inlet assembly 132 is used to control the on-off of the water inlet. The water inlet assembly 132 may include a second control switch 1321 and a water inlet pipe; the second control switch 1321 is arranged on the water inlet pipe for controlling the opening of the water inle...

Embodiment 3

[0081] Such as Figure 5 As shown, this embodiment provides different control methods of the electric water heater for the water in and out control unit 13 in different heating modes on the basis of the second embodiment.

[0082] In the embodiment of the present invention, before heating, the system first initializes each hardware interface and drive module, and judges whether the variable volume heating function is activated; when the variable volume heating is not activated, the system works in the working state of the whole tank heating, The water inlet component 132 of the system is turned on, the sewage component 131 is turned off, the heating function is started, and the normal water heater heating operation is performed; the control method in the whole tank heating mode will be introduced in detail below:

[0083] Optionally, when the heating mode is the whole tank heating mode, the water inlet and outlet control unit 13 automatically controls the water inlet and outle...

Abstract

The embodiment of the invention discloses an electric water heater. The electric water heater comprises an inner container and a heating device arranged in the inner container and further comprises awater inlet and outlet control unit and a microcontroller, which are arranged at the outer part of the inner container, wherein the microcontroller is used for controlling the water inlet and outlet control unit according to different heating modes so as to realize variable-capacity heating; the heating modes comprise a whole container heating mode and a half container heating mode; and the waterinlet and outlet control unit is used for automatically controlling the inlet water and / or outlet water of the inner container according to the control instruction of the microcontroller. Through thescheme of the embodiment, the intelligent and precise control of the variable-capacity heating of the electric water heater are realized, wastes are reduced, and the experience of users is improved.

Description

technical field [0001] Embodiments of the present invention relate to household appliance control technology, especially an electric water heater. Background technique [0002] At present, most electric water heaters only realize the switching of the heating function of the whole tank and half tank by changing the heating position; since water is a poor conductor of heat, when the heating tube located in the center of the inner tank is heated, the water below the heating tube will not When heated, only the upper part of the water is hot; this solution can reduce the heating time and achieve energy-saving effects when the hot water is sufficient. However, when this solution is implemented, it is first necessary to fill the inner tank with water. If the user does not need the hot water for the whole tank, water resources will be wasted; Energy waste; secondly, heating tubes at different positions need to be arranged in the inner tank, one heating tube must dive below the inne...
