The second hot water outlet connector 203 is further connected to the water outlet nozzle 300 so that the channel in the second hot water outlet connector 203 is connected to the first water outlet channel of the water outlet nozzle 300. When hot water is used, the heated hot water in the heating channel flows out from the first water outlet channel of the water outlet nozzle 300 through the hot water inlet connector 201 and the second hot water outlet connector 203 of the adapter structure 200. When warm water or boiled water is needed, the first hot water outlet connector 202 is connected to the heat exchanger, and the channel in the first hot water outlet connector 202 is connected to the heat exchange channel, so that the heated hot water in the heating channel enters the heat exchange channel through the hot water inlet connector 201 and the first hot water outlet connector 202 for heat exchange, thereby meeting the demand for warm water or boiled water.

Specifically, an anti-slip pattern is formed on the outer wall of the first hot water outlet connector 202 to ensure the stability of the connection between the connecting hose and the first hot water outlet connector 202. For example, the anti-slip pattern may be a zigzag pattern. In another embodiment, the first hot water outlet connector 202 may also be directly plugged into one end of the heat exchange channel of the heat exchanger.

[0036] Optionally, the warm water inlet connector 204 is connected to the heat exchanger via a connecting hose, so as to ensure the effective connection between the warm water inlet connector 204 and the heat exchanger. Specifically, an anti-slip pattern is formed on the outer wall of the warm water inlet connector 204 to ensure the stability of the connection between the connecting hose and the warm water inlet connector 204. For example, the anti-slip pattern may be a zigzag pattern. In another embodiment, the warm water inlet connector 204 may also be directly plugged into an end of the heat exchange channel of the heat exchanger away from the first hot water outlet connector 202.

The water tank 500 is used to facilitate water supply to the heater 100, thereby realizing the supply of hot water or warm water.

[0038] In this embodiment, the heat exchanger is arranged in the water storage cavity, and the liquid in the heat exchange channel can exchange heat with the liquid in the water storage cavity through the heat exchanger. By arranging the heat exchanger in the water storage cavity, it is convenient to use the water in the water storage cavity to exchange heat with the hot water in the heat exchange channel, avoiding the addition of other components for heat exchange with the liquid in the heat exchange channel, and reducing the number of parts. Specifically, the heat exchanger can be a heat exchange pipe, and the heat exchange pipe is arranged in the water storage cavity.

[0039] Optionally, the adapter structure 200 is located above the water tank 500, and the first hot water outlet connector 202 is arranged downward to facilitate the connection between the first hot water outlet connector 202 and the heat exchanger.

Specifically, a water vapor separation structure is formed in the water outlet 300. After the water heat enters the first water outlet channel of the water outlet 300, the water vapor separation structure is used to separate water vapor and water, so that the water vapor can be discharged from the steam return joint 206 and the steam outflow joint 207.

[0045] In this embodiment, the steam outflow joint 207 is used to connect to the water tank 500. When the water vapor enters the channel of the steam outflow joint 207 from the steam return joint 206 and is directly discharged into the water tank 500, it will gradually condense into liquid water. By discharging the water vapor into the water tank 500, the condensed water is recovered, avoiding the need to set up a separate component to collect the liquid water after the condensation of the water vapor. Specifically, the steam outflow joint 207 is arranged downward, so that the steam outflow joint 207 is easily connected to the water tank 500.

[0063] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0065] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
