Water storage type dual mode water heater

Abstract

The invention discloses a water storage type dual mode water heater which comprises an upper portion internal container, a lower portion internal container and a control circuit board. The upper portion internal container and the lower portion internal container are arranged inside an outer shell, the upper portion internal container and the lower portion internal container are mutually communicated, an instant sub-container is arranged in the upper portion internal container, and an instant sub-container water inlet tube, an instant heating tube, a temperature sensor and a dry-heating temperature controller are arranged on the instant sub-container. A drain outlet is formed at the bottom end of the lower portion internal container. A preheating heating tube, a temperature sensor, a dry heating temperature controller and a water inlet tube are arranged in the lower portion internal container, wherein one end of the water inlet tube is welded in the lower portion internal container. The control circuit board is respectively connected with a temperature probe, the instant heating tube, the preheating heating tube, the temperature sensors and the dry heating temperature controllers through signal lines. The water storage type dual mode water heater can achieve machine automatic protection, and adds the advantages of cleaning convenience, speediness and stability.

Description

technical field [0001] The utility model relates to a water storage type double-mode water heater, which is mainly used in the family bathing field. Background technique [0002] The pre-heating dual-mode water heaters currently on the market cannot automatically set the instant heating mode or the preheating mode. They only manually set the instant heating mode or the preheating mode and cannot automatically switch the heating mode. The number of water valves will easily cause the wear of the machine, thereby increasing the wear rate of the machine. The pre-dual-mode water heaters on the market, when bathing in colder winter, will feel the disadvantages of less water and low temperature. In fact, there is still a lot of warm water in the tank causing waste, which is not conducive to environmental protection, and the user also feels very inconvenient. Contents of the invention [0003] In order to solve the above problems, the utility model provides a water storage type d...

Problems solved by technology

[0002] The pre-instant dual-mode water heaters currently on the market cannot automatically set the instant heating mode or the preheating mode. The number of water valves will easily cause the wear of the machine, thereby increasing the wear rate of the machine. The pre-dual-mode water heaters on the market, when bathing in colder winter, will feel the disadvantages of less water and low temperature, which cannot be maximized. In fact, there is still a lot of warm water in the tank causing waste, which is not conducive to environmental protection, and users also feel very inconvenient
