Ceiling-hidden-type electric water heater

Abstract

The invention discloses a ceiling-hidden-type electric water heater. The ceiling-hidden-type electric water heater comprises an outer shell, a heat-preservation layer, an inner container, a heater, a water inlet pipe, a water outlet pipe, a magnesium rod and a hanging frame, wherein the heater is located between the water inlet pipe and the water outlet pipe, the heater, the water inlet pipe, the water outlet pipe and the magnesium rod are connected into the inner container from the lateral end of the inner container, the water inlet pipe moves downwards to be near the lower wall of the inner container and is arranged horizontally, the water outlet pipe moves upwards to be near the upper wall of the inner container and is arranged horizontally, the tail ends of pipe openings of the water inlet pipe and the water outlet pipe are sealed, a plurality of water inlet holes are evenly distributed in the lower side of the pipe body of the water inlet pipe, and a plurality of water outlet holes are evenly distributed in the upper side of the pipe body of the water outlet pipe. Through the lateral water outlet design scheme of the ceiling-hidden-type electric water heater, the diameter of the inner container can be increased, the length of the inner container is increased, the volume is increased, the thickness of the heat-preservation layer is increased, the hot water outlet efficiency is higher, and the energy-saving effect is better.

Description

[0001] technical field [0002] The invention relates to an electric water heater, in particular to a ceiling hidden electric water heater. [0003] Background technique [0004] With the development of society and higher real estate prices, in order to meet the needs of the market, many real estate developers specially design and develop small and medium-sized houses. The house structure is more simple and practical, and the bathroom area is smaller and the space is more compact. Therefore, users in many cities now have increasingly demanding requirements for electric water heaters, but the current instant water heaters are small in size and have a high threshold for power consumption, requiring 6 square meters of wires to meet the power demand. Although the water storage water heater has a low threshold for power consumption, it is bulky and has a slow heating speed, so it cannot be installed in a concealed manner. Some brands also use semi-concealed installation, and the...

Problems solved by technology

[0006] Therefore, the traditional down-flow electric water heater wants to be installed in a hidden way, and the volume of the inner tank needs to be larger. There is no choice but to lengthen the length of the inner tank. For a water heater with a diameter of 28cm, the diameter of the inner tank is 240mm, and the insulation layer is only 20mm, so the insulation effect is poor and the energy efficiency ratio is low. At the same time, because the length of the inner tank is too long, exceeding 105cm, because the hot water outlet is generally located in the middle, the hot water at both ends will become a dead angle, which reduces the hot water output rate. , the same waste of energy consumption, not energy-saving
