Problems solved by technology
[0003] The present invention aims at the problem that too many antifreeze heating parts lead to increased cost or too few antifreeze heating parts lead to poor antifreeze effect, and proposes a water heater and its antifreeze heating part determination method and antifreeze control method. The determination method of antifreeze heating parts and the antifreeze control method can achieve the technical effect of ensuring the antifreeze effect while avoiding increasing costs

The invention relates to a water heater and a determination method and an anti-freezing control method of an anti-freezing heating part of the water heater. The water heater comprises a pipeline, a shell and the anti-freezing heating part, and the pipeline is arranged in the shell. The heat loss rate of the anti-freezing heating part of the water heater is obtained; the anti-freezing heating partwith the size corresponding to the heat loss rate is selected according to the heat loss rate; and the selected anti-freezing heating part is arranged on the pipeline and located in the shell. Due tothe fact that the anti-freezing heating part is selected according to the heat loss rate, and the size of the anti-freezing heating part and the heat loss rate are in a positive correlation relation,when the heat loss rate of the water heater is large, the anti-freezing heating part with a large size is correspondingly selected, it is guaranteed that the anti-freezing heating part can overcome heat loss and meanwhile guarantee heating of the pipeline, and the anti-freezing effect is guaranteed; and when the heat loss of the water heater is small, the anti-freezing heating part with a small size can be correspondingly selected, and the cost increase caused by overlarge size of the anti-freezing heating part is avoided.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to a method for determining a water heater and an antifreeze heating element thereof, and an antifreeze control method. Background technique [0002] When the traditional gas water heater is in use, it generally realizes heat exchange with the water flow in the pipeline by means of a heat exchanger. However, in winter or in an environment with low temperature, when the water heater is not in use, the water in the pipeline is easy to freeze, and the volume of the water expands after freezing, which in turn causes the frozen water to easily swell the pipeline. The traditional antifreeze method is to install an antifreeze heating element on the pipeline, and use the antifreeze heating element to heat the pipeline to avoid freezing and cracking of the pipeline. However, in the traditional antifreeze heating element setting method, if the antifreeze heating element is set too much...
