Heating-capacity-adjustable water heater

Abstract

The invention discloses a heating-capacity-adjustable water heater. The heating-capacity-adjustable water heater comprises a heat-preserving tank body, wherein the upper part of the left side of the heat-preserving tank body is communicatively connected with a water inlet, the right side of the lower part of the heat-preserving tank body is communicatively connected with a water outlet, and a heating tube, a temperature detector and a float valve are arranged in a chamber of the heat-preserving tank body; the top part of the heat-preserving tank body is additionally provided with a first through hole and a second through hole, the two ends of a connecting pipe are respectively and communicatively connected with the first through hole and the second through hole, and the middle part of the connecting pipe is communicatively connected with a one-way exhaust valve; the two ends of the heating tube are fixedly arranged on the inner walls of the left and right sides of the heat-preserving tank body, the top part of the heat-preserving tank body is provided with an insertion hole, a secondary heating tube is inserted and fixed in the insertion hole and the secondary heating tube stretches into the heat-preserving tank body. The heating-capacity-adjustable water heater has the advantages that the power consumption can be greatly reduced, the heating effect is good, water steam can be further cooled and then flows back again, the exhaust of the water steam is reduced and the amount of used water is reduced; since the secondary heating tube can be assembled and disassembled, the heating capacity of the water heater is increased and the heating speed is improved.

Description

Technical field: [0001] The invention relates to the technical field of water heaters, and more specifically to a water heater with adjustable heating capacity. Background technique: [0002] Existing water tanks are generally equipped with an exhaust valve to allow excessive steam in the water tank to be discharged from the exhaust valve to ensure the normal use of the water tank. However, the discharged water vapor actually takes away part of the water and heat. Greatly increase the waste and consumption of water. [0003] Moreover, generally only one heating device is installed in the water tank, and the heating device needs to be repaired if the heating device is damaged, and the heating capacity of the heating device is fixed and cannot be adjusted. Summary of the invention: [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a water heater with adjustable heating capacity, which can greatly reduce power consumption and ha...
