Water heating assembly for water heater and water heater applying water heating assembly

Abstract

The invention relates to a water heating assembly for a water heater and the water heater applying the water heating assembly. The water heating assembly comprises an air chamber, a water tank, a heating piece and a bubble generating part, wherein the air chamber is provided with an inner cavity; the side wall of the air chamber is provided with an air inlet hole and an air outlet hole which are both in fluid communication with the inner cavity; the water tank is internally provided with a cavity; the side wall of the water tank is provided with a water inlet, a gas inlet and a bubble water outlet which are all in fluid communication with the cavity; the water tank is located on the downstream of the gas chamber in the flowing direction of gas; the gas inlet in the water tank is in fluid communication with the gas outlet; the heating piece is arranged on the gas chamber and is used for heating gas in the gas chamber; and the bubble generating part is arranged in the cavity of the water tank and used for mixing water and gas in the cavity to generate bubble water, so that the heating speed is increased, and the use amount of water is reduced.

Description

technical field [0001] 本发明涉及热水器技术领域,具体涉及一种用于热水器的水加热组件及应用有该组件的热水器。 Background technique [0002] 目前的热水器主要为电热水器和燃气热水器,电热水器加热速度慢,在使用前一段时间,需要提前进行加热;为了解决加热速度慢的问题,如专利号为CN200720107892.0(公告号为CN201014706Y)的中国实用新型专利公开了一种《快速电热水器》,在壳体内竖向设置四根相互连通的加热水管,加热时水温连续上升,加热速度快,达到即热的目的,但是这样需要设置较多的加热管。 [0003] 燃气热水器虽然加热速度较快,但是也需要一定的时间,并且燃气热水器的加热速度越快,能源消耗越大,另外目前的燃气热水器正常出热水前,滞留于热水管内的余水和未达设定温度的冷水会被大量浪费。针对这一问题,一般会设置储水箱,以缓冲水温波动,避免前段的凉水白白流掉造成水资源浪费。如专利号为CN201920717666.7(公告号为CN209893652U)的中国实用新型专利公开的《一种节能环保型燃气热水器管路结构》所示,包括第一供水管路、燃气热水器、第二供水管路、密闭储水器、第三供水管路和水龙头,第一供水管路与燃气热水器的进水口连接,燃气热水器的出水口与密闭储水器的进水口通过第二供水管路连接,密闭储水器的出水口与水龙头通过第三供水管路连接,该专利解决了燃气热水器在关闭后重启时供水温差较大,导致水资源和燃气资源浪费的问题,并且能快速流出热水。 [0004] 但是储水箱需能够保温,否则并不能从根本上解决问题,因为热水器若在关闭后短时间内再次开启,储水器内的水会依然温度较高,否则长时间后储水器内的水温会降低,流出的依然是冷水;而储水器要达到保温的效果,要么设置保温层,要么设置加热件,这样也会导致成本增高,并且能源消耗较高。 [0005] 另外,目前的热水器,在正常使用过程中的热水都会有90%被浪费,比如用户在沐浴时,不需要太大的水流量,但是水流量太小又会影响沐浴体验,故用户索性会大流量进行冲洗,就会造成水资源浪费和能源消耗。 Contents of the invention [0006] 本发明所要解决的第一个技术问题是针对现有技术的现状,提供一种通过在水中混入空气以提高加热...

AI Technical Summary

Problems solved by technology

[0004] However, the water storage tank needs to be able to keep warm, otherwise the problem cannot be solved fundamentally, because if the water heater is turned on again in a short time after being turned off, the water in the water storage will still be at a higher temperature, otherwise the water temperature in the water storage will be lower after a long time. It will be lowered, and the outflow is still cold water; and to achieve the effect of heat preservation, the water storage must either be equipped with an insulation layer or a heating element, which will also lead to increased costs and higher energy consumption

[0005] In addition, in current water heaters, 90% of the hot water during normal use will be wasted. For example, when users take a bath, they do not need too much water flow, but too small water flow will affect the bathing experience, so users simply will Flushing with a large flow will cause waste of water resources and energy consumption
