Embodiment 1

[0025] In this embodiment, the water heater is a gas water heater. Those skilled in the art can predict that the pipeline structure of the present invention is also suitable for other types of water heaters (such as electric water heaters). The arrows in the drawings indicate the direction of water flow.

[0026] Such as figure 1 , 2 As shown in and 3, a zero-cold water heater capable of automatically preheating includes a water heater body (1), a heat exchange device (2), an internal water inlet pipeline (3), a water inlet joint (4), and an internal water outlet pipeline (5 ), a water outlet joint (6), a preheating circulation pump (7), a circulation pump controller (8), a wireless signal receiver (9) and a water outlet terminal controller (10), and the water outlet terminal controller (10) includes Pressure difference sensor (201), temperature sensor (202), three-way valve (203), switch control motor (204), water flow power generation device (205), power storage device (206...

Embodiment 2

[0028] Such as figure 1 , 2 As shown in and 3, a zero-cold water heater that can automatically preheat, the temperature sensor (202), the three-way valve (203) and the switch control motor (204) together form a temperature control switch, and the information processing unit (207) according to the temperature The real-time water temperature detected by the sensor (202) controls the working state of the three-way valve (203) through the switch control motor (204). The information processing unit (207) can process the pressure difference signal detected by the pressure difference sensor (201), and finally control it through the wireless signal transmitter (208), the wireless signal receiver (9) and the circulation pump controller (10) Opening and closing of preheating circulation pump (7). The water flow power generation device (205) can generate electric energy and store it in the power storage device (206), which is a pressure difference sensor (201), a temperature sensor (20...

Embodiment 3

[0030] Such as figure 1 , 2 As shown in and 3, a zero-cold water heater that can automatically preheat, the preheating circulation pump (7) includes an on state and an off state, and the on and off of the preheating process is realized through the above two state transitions, the on state and the off state The state transition process is as follows:

[0031] 1. Water heater preheating is automatically turned on: when the user starts to use water, the water mixing valve (13) is opened. At this time, the pressure difference sensor (201) detects an obvious pressure difference, and the rear sensor transmits the pressure difference signal to the information processing unit (207). After the difference signal is processed, it is transmitted to the wireless signal receiver (9) through the wireless signal transmitter (208), and finally the pressure difference information generates a preheating circulating pump (7) start command in the circulating pump controller (8), preheating After...

Abstract

The invention relates to the field of water heaters, in particular to an automatic-preheating cold-water-avoiding water heater. The automatic-preheating cold-water-avoiding water heater comprises a water heater body, a heat exchange device, an internal water inlet pipeline, a water inlet connector, an internal water outlet pipeline, a water outlet connector, a preheating circulating pump, a circulating pump controller, a wireless signal receiver and a water outlet terminal controller. By coordinative operation of the water outlet terminal controller and the preheating circulating pump, automatic preheating of cold water in a water heater pipeline can be realized in water consumption at a terminal water outlet, then hot water at an appropriate temperature flows out of the terminal water outlet after preheating, and accordingly user experience is improved, and water resource saving and user cost reduction are realized.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a zero-cold water heater capable of automatically preheating. Background technique [0002] At present, the waterway structure of zero cold water gas water heaters on the market is divided into two-pipe scheme and three-pipe scheme. The zero cold water gas water heater adopting the two-pipe scheme is mainly connected in series with a preheating circulation pump in the water circuit inside the machine. The zero-cold water gas water heater adopting the three-pipe scheme has a bypass branch connected to the return water joint at the water inlet end of the machine, and a preheating circulation pump and a one-way valve are arranged on the bypass branch. At present, the zero-cold water gas water heater mainly adopts the three-pipe scheme, but the three-pipe scheme needs to lay a return pipe in advance, the initial investment cost of the user is high, and it is difficult to modif...
