Water heater with residual hot water collection device and control method of water heater.

Abstract

The invention discloses a water heater with a residual hot water collection device and a control method of the water heater. The water heater with the residual hot water collection device comprises awater heater inner container and a water outlet pipe communicating with the water heater inner container. The hot water collection device is further included. The hot water collection device comprisesa heat preservation container for collecting hot water. A hot water outlet of the heat preservation container communicates with the water outlet pipe through a communication pipeline, and a control assembly for controlling conducting of the communication pipeline is arranged on the communication pipeline; and conducting between a water outlet of the hot water collection device and the water outlet pipe of the water heater is achieved by controlling the control assembly, and the hot water in the hot water collection device is used again. The prevention of the waste of hot water resources and the waste of electricity for repeatedly heating the water in the water heater inner container is achieved by additionally arranging the hot water collection device and the more intelligent control method; and the energy consumption of the water-storage-type electric water heater is reduced, and the water heater is more energy-saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of water storage water heaters, and in particular relates to a water heater with a surplus hot water collecting device and a control method thereof. Background technique [0002] In the existing water storage type electric water heater, the temperature of the hot water in the inner tank is in a state of gradient distribution during the heating process, the water temperature at the top is high, and the water temperature at the bottom is low. After taking a bath with a storage type electric water heater, there will be a certain amount of hot water remaining on the top of the inner tank of the water heater. If this part of hot water is not collected, it will slowly mix with the cold water at the bottom, reducing the temperature of the top water, and it is no longer available for bathing. , If you turn off the water heater after using hot water, and want to use a small volume of hot water again, you must turn on the water...

AI Technical Summary

Problems solved by technology

When the hot water collected by the system is reused, put the cold water in the water heater into the ordinary water tank and then send the collected hot water to the water heater. This will inevitably increase the investment in equipment, occupy space, and also affect the heating of the water heater. When the collected hot water runs out, you will fall into the embarrassing situation that there is no hot water available
