Embodiment 1

[0064] like figure 1 As shown, the water heater in this embodiment includes a controller 1 , a heat exchanger 2 and a first temperature sensor 3 .

[0065] Wherein, the heat exchanger 2 includes a main body structure 4, a first pipeline 5 and a second pipeline 6 that run through the main structure 4 and are independent of each other, the first pipeline 5 is arranged on the water outlet main pipeline of the water heater, and the second pipeline The channel 6 is used to store the buffer solution for heat exchange with the water flowing through the first pipeline 5 .

[0066] The first temperature sensor 3 is electrically connected to the controller 1, the first temperature sensor 3 is arranged at the water outlet end of the heat exchanger 2, and the first temperature sensor 3 is used to obtain the outlet water temperature and send it to the controller 1;

[0067] When the water heater is turned on for heating, the controller 1 is used to control the water heater to operate at t...

Embodiment 2

[0099] like Figure 4 As shown, the water heater of this embodiment is a further improvement to Embodiment 1, specifically:

[0100] In order to achieve a better temperature control effect of the outlet water, a heating module 10 is arranged in the heat exchanger 2 , the heating module 10 is arranged in the second pipeline, and the heating module 10 is electrically connected to the controller 1 .

[0101] When the water is turned on again after stopping the water for a set period of time, the controller 1 is used to control the heating module 10 to start heating the buffer in the second pipeline when the temperature of the buffer is lower than the set temperature; When the set temperature is reached, the heating module 10 is controlled to stop heating the buffer solution in the second pipeline.

[0102] Through the setting of the heating device, the temperature of the buffer solution is always kept at the preset buffer solution temperature, so as to ensure that the user can u...

Embodiment 3

[0116] like Image 6 As shown, the water heater of this embodiment is a further improvement to Embodiment 1 or 2, specifically:

[0117] The main structure of the heat exchanger 2 in this embodiment includes a cover plate 12 , a bottom plate 13 , a plurality of first metal sheets 14 and a plurality of second metal sheets 15 .

[0118] The first metal sheet 14 and the second metal sheet 15 are stacked between the cover plate 12 and the bottom plate 13, and the cover plate 12 is covered on the bottom plate 13; in an optional embodiment, the first metal sheet 14 and the second metal sheet The metal sheets 15 are sequentially stacked between the cover plate 12 and the bottom plate 13 .

[0119] The cover plate 12 is provided with a buffer solution inlet hole P1, a user water inlet hole P2 and a user water outlet hole P3;

[0120] Wherein, the surface of each first metal sheet 14 is provided with a buffer flow channel 16, and each buffer flow channel 16 is in communication with t...

Abstract

The invention discloses a water heater and a control method thereof. The water heater comprises a controller, a heat exchanger and a first temperature sensor. When the water heater is started for heating, the controller is used for controlling the water heater to operate at a target power until the water outlet temperature reaches a preset temperature; and when the water outlet temperature reachesthe preset temperature, the temperature of a buffer solution is equal to the preset temperature. And when a user uses water again after stopping water use within a set time period, the buffer solution in the second pipeline is used for carrying out heat exchange on the water flowing through a first pipeline. According to the water heater and the control method, when the user uses water again after temporarily stopping water, quick response is achieved through the good heat exchange performance of the heat exchanger, the effect of weakening temperature fluctuation is achieved, the advantages that the heat exchange speed is rapid, and the temperature is uniform after heat exchange are achieved, and therefore temperature changes caused by fluctuation of water flow, pressure and the like areeffectively avoided. The temperature increase speed is high when water is discharged for the first time, the time for the user to wait for hot water discharge is shortened, and the use experience of the user is effectively improved.

Description

technical field [0001] The invention relates to the technical field of water temperature control, in particular to a water heater and a control method thereof. Background technique [0002] The user temporarily suspends the water during the use of the water heater (such as washing hair, using shower gel), and there will be a large temperature change when the water comes out again. It is first necessary to consume part of the lower temperature water in the outer pipeline, and then consume warmer water. Fluctuations in gas pressure and water flow will also cause fluctuations in water temperature, and it will take a long time for the water temperature to return to the set value. Fluctuations in water temperature will reduce the user experience and may even burn the user. [0003] There is technology to add a water mixing device on the water outlet pipeline at present, and this device is made up of water inlet pipe, water outlet pipe and cavity container, and hot water can be m...
