Embodiment 1

[0034] This embodiment proposes a water heater instant heating device, such as figure 1 As shown, it includes a preheating water tank 11 containing an electric heating device. The water inlet of the preheating water tank 11 is connected with the water heater outlet pipe 13 through the water inlet pipe 12, and the water outlet of the preheating water tank 11 is connected to the water point through the water outlet pipe 14. The water inlet pipe 12 and the water heater outlet pipe 13 are respectively connected to the two ends of the temperature control valve 15, and the third end of the temperature control valve 15 is connected to the water outlet pipe through the water outlet branch pipe 16, as figure 2 , image 3As shown, the temperature control valve 15 includes a valve body 151. The valve body 151 has a valve cavity 152 with three valve ports. The three valve ports are respectively the inlet 153 connected to the water heater outlet pipe 13 and the inlet to the preheating wat...

Embodiment 2

[0044] This embodiment proposes a control method for an instant-on and instant-heating device of a water heater, including the instant-on and instant-heating device for a water heater as described in Embodiment 1. For details, please refer to Embodiment 1 and the appended Figure 1-3 , without going into details here, the instant water heater instant heating device control method of this embodiment includes the following steps:

[0045] S1. The electric heating device is powered on to heat the water in the preheating tank to the set temperature;

[0046] S2. When the temperature of the water flowing out of the outlet pipe of the water heater is greater than or equal to the set temperature, the head of the first pipeline seals the first outlet, the head of the second pipeline opens the second outlet, and the outlet pipe of the water heater passes through the temperature control valve and the outlet pipe Connected, used to supply hot water for water points;

[0047] When the te...

Abstract

The invention discloses an instant-starting instant-heating device for a water heater and a control method for the instant-starting instant-heating device. The instant-starting instant-heating device for the water heater comprises a preheating water tank with an electric heating device therein, wherein a water inlet of the preheating water tank is connected with a water outlet tube of the water heater through a water inlet tube; the water inlet tube and the water outlet tube of the water heater are separately connected to the two ends of a temperature control valve; a third end of the temperature control valve is connected to the water outlet tube through a water outlet branch tube; the temperature control valve comprises a valve body; a valve cavity with three valve openings is arranged in the valve body; the three valve openings are separately an inlet connected with the water outlet tube of the water heater, a first outlet connected with the water inlet of the preheating water tank and a second outlet connected with the water outlet branch tube; a first pipeline end socket used for opening or sealing the first outlet is arranged in the valve cavity; and a second pipeline end socket used for opening or sealing the second outlet is arranged at one side of the second outlet. The instant-starting instant-heating device for the water heater realizes the effect that hot water instantly flows out, so that no cold water is discharged and long-time waiting is not needed, and therefore, bathing comfort of a user is improved and waste of water resources is reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an instant heating device for a water heater and a control method thereof. Background technique [0002] Due to the long distance between the installation location and the bathroom, the existing gas water heaters and solar water heaters need to be transported through water pipes for long distances. The length of the water pipes is about ten meters. A large amount of cold water not only causes a waste of water resources, but also seriously affects the user's water experience. [0003] Existing water heater solutions can be classified into the following two types: [0004] One is to install a return pipe between the water heater outlet pipe and the water inlet pipe, and install a circulation pump on the circulation pipe composed of the water heater, outlet pipe, and return water pipe. When the user needs water, turn on the circulation pump in advance. The circulation pump d...
