Problems solved by technology

[0003] However, instant electric water heaters also have certain safety hazards. After use, water will often remain in the water guide pipes and the pipes in the heating body. When the ambient temperature is low, it will cause the accumulated water in the pipeline and the heating body to freeze, causing the pipeline to freeze and crack and damage the water heater.
[0004] In order to solve the above problems in the prior art, the pipes are heated at certain time intervals in winter. However, due to the different use environments and usage times of water heaters, in some cases, the heating antifreeze effect provided by the prior art does not not ideal

Embodiment 1

[0046] In this example, if figure 1 As shown, an antifreeze control method for a water heater is provided. The water heater includes a heating body with a pipeline inside. The above antifreeze heat determines the antifreeze preset parameters of the heating body; when the water temperature in the pipeline is too low, the water heater turns on the antifreeze, and adjusts the antifreeze preset parameters of the heating body in combination with the external ambient temperature and time information, so that the heat generated meets the heating body Antifreeze needs.

[0047] In this embodiment, the antifreeze heat is calculated by the water heater through the heat calculation formula according to the specific heat capacity of the heating body and water, the mass of the heating body itself and the water in the pipeline, and the temperature change value of the temperature rise of the water. However, the antifreeze heat is only the minimum heat produced by the heating body to meet th...

Embodiment 2

[0072] Such as figure 2 As shown, this embodiment refines the steps of adjusting the heating time according to the time information on the basis of embodiment 1, and its difference from embodiment 1 is as follows:

[0073] In this embodiment, the control method further includes: if the specific moment when the antifreeze is turned on is at night, further judging the time from sunrise at the specific time and comparing it with the preset time, if the time from sunrise is longer than the preset time , the heating time is extended by a first multiple, and if the time from sunrise is shorter than the preset time length, the heating time is extended by a second multiple, and the first multiple is greater than the second multiple.

[0074] In this embodiment, due to the long duration of nighttime, the ambient temperature continues to drop from sunset to midnight, and slowly rises before sunrise. Therefore, the actual ambient temperature changes at different time periods at night. In...

Embodiment 3

[0092] This embodiment further refines the judgment logic of the antifreeze control method on the basis of embodiment 1 or 2, and its difference from embodiment 1 or 2 is as follows:

[0093] In this embodiment, the control method further includes: if the specific time for turning on the antifreeze is at night, shortening the heating interval while prolonging the heating time; shortening the heating interval according to the time information is smaller than shortening the heating interval according to the external ambient temperature .

[0094] In this embodiment, when it is determined that the antifreeze is turned on at night, in addition to adjusting the heating time, the heating interval is also adjusted to deal with the situation that the heating interval cannot meet the antifreeze requirements due to the sudden drop in temperature at night in winter.

[0095] Other implementation modes of this embodiment are the same as Embodiment 1 or 2.

Abstract

The invention discloses an antifreeze control method for a water heater and the water heater. The water heater includes a heating body provided with pipelines inside. The antifreeze heat determines the antifreeze preset parameters of the heating body; when the water temperature in the pipeline is too low, the water heater turns on the antifreeze, and adjusts the antifreeze preset parameters of the heating body in combination with the external ambient temperature and time information, so that the generated heat meets the requirements of the heating body. antifreeze requirements. The antifreeze control method provided by the invention can be carried out in the standby state of the water heater, and when the temperature of the water body in the water heater is low, the heating parameters of the heating body are adjusted according to the ambient temperature and time information to ensure the antifreeze effect.

Description

technical field [0001] The invention belongs to the field of water heater antifreeze technology, and in particular relates to a water heater antifreeze control method and the water heater. The antifreeze control method provided by the invention calculates the antifreeze according to the water volume in the heating body and the pipeline when the temperature of the water body in the water heater is low. In addition to the required heat, the heating interval and heating time of the heating body are further adjusted according to the external environment temperature and time information, so as to ensure the antifreeze effect of the water heater in any environment. Background technique [0002] The instant water heater is a kind of hot water flow that can be obtained quickly through the electric heating body, and the heating parameters can be adjusted through the controller, such as heating power, heating time, heating interval, etc., so that the water temperature can meet the diff...
