Horizontal positive-displacement energy-saving electric water heater

Abstract

The invention is a transversal volumetric energy-saving electric water heater, comprising casing, inner container, cold water inlet pipe and hot water outlet pipe combined with the inner container, temperature sensor and heating component equipped in the inner container, and heating controller connected with the temperature sensor and the heating component, where a baffle for stopping cold and hot water directly mixing is arranged in the inner container, one end and two sides of the baffle are connected with the inner container and the other end is a space apart from the end face of the inner container and the space acts as a channel for cold water to enter hot water region; the part of the cold water inlet pipe inserted in the inner container is in the bottom of the inner container and the cold water outlet is opposite to and close to the end face of the inner container connected with the baffle; the part of the hot water outlet pipe inserted in the inner container is on the top of the inner container and the hot water inlet is opposite to and close to the end face of the inner container connected with the baffle. And it not only reduces the mixing degree of cold and hot water in the inner container but also solves the short-circuit problem between the cold water outlet and the hot water inlet.

Description

technical field [0001] The invention belongs to the field of water heaters, in particular to a horizontal electric water heater. Background technique [0002] Water heaters are one of the most power-consuming appliances in households. Compared with vertical electric water heaters, horizontal electric water heaters consume more power. The industry has begun to realize this problem and has begun to develop various energy-saving technologies for water heaters. For the energy saving of water heaters, the methods commonly used in the industry include improving the thermal insulation effect of the insulation layer, increasing the thermal efficiency of the heating pipe, and improving the control accuracy of the thermostat, etc. (Fu Junping, "Energy saving of electric water heaters has become the development direction", Electric Appliance, 2004 7 issues). Existing technology focuses on adding more complex devices, such as one of the largest water heater ...

AI Technical Summary

Problems solved by technology

Although the above technical measures have all produced different degrees of energy-saving effects, due to the water outlet of the cold water input pipe and the water inlet of the hot water output pipe in the inner tank of the water heater figure 1 Due to the layout and structure shown, short flow is likely to occur between the water outlet of the cold water input pipe and the water inlet of the hot water output pipe, and the cold water entering the inner tank is strongly mixed with the original hot water in the inner tank, resulting in energy saving. The improvement of the effect is limited

Furthermore, the above energy-saving methods all need to add other devices or adopt high-cost technical means to achieve the purpose of energy-saving
