Water heater

Abstract

The invention provides a water heater. The water heater comprises a water outlet pipe, a water supply valve group, a functional liquid input device and a flow statistics device. The tail end of the water outlet pipe is connected with a first water distribution pipe and a second water distribution pipe. The water supply valve group is configured to open the first water distribution pipe and close the second water distribution pipe under the condition that the water heater operates in the first water outlet mode. The functional liquid input device is configured to be started under the condition that the water heater operates in the first water outlet mode so as to convey bath foam to the water outlet pipe to mix the bath foam into hot water output by the first water distribution pipe. The flow statistics device is used for carrying out statistics on the usage amount of the bath foam, and when the usage amount of the bath foam is larger than or equal to the preset usage amount, the water heater enters the second water outlet mode, the functional liquid input device is shut down, and the water supply valve group closes the first water distribution pipe and opens the second water distribution pipe. According to the water heater, it can be guaranteed that a user enjoys a healthy bathing function, and meanwhile the phenomenon that the bath foam is wasted or excessively used is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater. Background technique [0002] Water heaters are indispensable household appliances for every family now, but although current water heaters can meet everyone's basic needs for hot water bathing, they cannot meet people's growing needs for healthy bathing. In some existing water heaters that use a medicated bath chamber, the medicated bath liquid will fill the entire waterway. While taking a bath, the water points such as washing vegetables and hand washing in the kitchen will also be occupied by the medicated bath liquid, resulting in other water outlet points that cannot be used at the same time when taking a bath. In addition, this method will make the bath liquid flow through the heat exchanger with the water flow from the water heater inlet, and some substances in the bath liquid will adhere or deposit on the inner wall of the heat exchanger, which will ...

[0002] Water heaters are essential household appliances for every family nowadays, but although the current water heaters can meet everyone's basic needs for hot water bathing, they cannot meet people's growing demand for healthy bathing

In some existing water heaters that use a medicated bath chamber, the medicated bath liquid will fill the entire waterway. While taking a bath, the water points such as washing vegetables and handwashing in the kitchen will also be occupied by the medicated bath liquid, resulting in other water outlet points that cannot be used at the same time when taking a bath.

In addition, this method will make the bath liquid flow through the heat exchanger with the water flow from the water heater inlet, and some substances in the bath liquid will stick or deposit on the inner wall of the heat exchanger, which will affect the heat exchange efficiency

Moreover, it is also difficult to deal with the problem of low heat exchange efficiency due to fouling inside the water heater
