When the water temperature of the water in the water storage cavity 101 is too high, a drainage mode can be adopted, and cold water is introduced into the water storage cavity 101 by the drainage assembly according to the detection result of the first temperature detection assembly 20, so that the temperature of the water in the water storage cavity 101 is reduced to a certain temperature, the temperature of the water discharged from the first water outlet 102 is not too high, the possibility that peripheral parts or a sewer line are burnt by the water discharged from the water storage cavity 101 is reduced, and the water storage cavity is more convenient and safer during maintenance or cleaning.

According to some embodiments of the present invention, as shown in fig. 1, the first water outlet 102 is disposed at the bottom of the water storage member 10, the first temperature detecting component 20 is disposed at the bottom of the water storage chamber 101 and is used for detecting the temperature of the bottom of the water storage chamber 101, the water outlet 303 of the water inlet component 30 is disposed at the bottom of the water storage chamber 101, and the water outlet 303 of the water inlet component 30 faces the bottom wall of the water storage chamber 101 or faces the lower part of the side wall of the water storage chamber 101. The first drain opening 102 is disposed at the bottom of the water storage member 10, so that the water in the water storage member 10 can be drained as much as possible in the drain mode. The first temperature detecting assembly 20 may be used to detect the temperature of water at the water storage chamber 101 near the bottom wall, may be used to detect the temperature at the lower portion of the circumferential side wall of the water storage chamber 101, or may be directly used to detect the temperature of water at the first drain outlet 102.

Therefore, the hot water assembly 100 of the invention can adapt to more drainage scenes, has stronger adaptability and better use effect, can reduce the possibility that peripheral parts or sewer pipes are scalded by water discharged from the water storage cavity 101, and is more convenient and safer during maintenance or cleaning.

According to some embodiments of the present invention, as shown in fig. 1, the water inlet assembly 30 includes a water inlet pipe 301 and a baffle member 302, the baffle member 302 is disposed in the water storage chamber 101, and a water mixing chamber is defined between the baffle member 302 and the bottom wall of the water storage member 10; alternatively, the baffle 302 defines a mixing chamber; the outlet end of the water inlet pipe 301 extends into the water mixing cavity, and the outlet of the water mixing cavity is the water outlet 303 of the water inlet assembly 30. Here, the water inlet pipe 301 may penetrate through the sidewall of the water storage member 10, and the outlet end of the water inlet pipe 301 may extend downward to the bottom of the water storage chamber 101; alternatively, the water inlet pipe 301 may be provided to penetrate the bottom wall of the water storage member 10, and the outlet end of the water inlet pipe 301 is located at the bottom of the water storage chamber 101. The blocking member 302 may be directly fixed to the bottom wall of the water storage member 10, and the blocking member 302 may be directly fixed to the water inlet pipe 301. The cold water discharged from the outlet end of the water inlet pipe 301 is mixed with the hot water in the water storage cavity 101 in the water mixing cavity, and by arranging the water mixing cavity, the flow speed of the water entering the water storage cavity 101 can be reduced, and the flow direction of the water entering the water storage cavity 101 is changed, so that the cold water is mixed with the water at the bottom of the water storage cavity 101 as much as possible.

According to some embodiments of the present invention, as shown in fig. 1 to 3, the stopper 302 is a cover having a bottom opening and a side opening, the bottom wall of the water storage member 10 covers the bottom opening, and the side opening is formed as the water outlet 303 of the water inlet assembly 30. That is, the cover body is directly installed on the bottom wall of the water storage member 10, so that the structure is simpler, the installation is convenient, and the damage is not easy to occur.

More specifically, as shown in fig. 3, for example, the cover may include a circumferential side plate and an upper end plate, the circumferential side plate is connected to a circumferential part edge of the upper end plate, the circumferential side plate includes a flange for connection to a bottom wall of the water storage member 10, the water inlet pipe 301 is provided through the upper end plate, and an outlet end of the water inlet pipe 301 is located below the upper end plate.

More specifically, the blocking member 302 is a housing, which is fixed to the outlet end of the water inlet pipe 301, and is provided with a plurality of water outlet holes, which are oriented towards the bottom wall of the water storage chamber 101 and/or towards the lower part of the side wall of the water storage chamber 101, and which are defined as water outlets 303 of the water inlet assembly 30.

According to some embodiments of the present invention, the first drain port 102 is configured to be opened when the detection result of the first temperature detecting assembly 20 is less than the first set temperature, and the water inlet assembly 30 is configured to switch between a first state in which water is supplied to the water storage chamber 101 and a second state in which water is stopped from being supplied to the water storage chamber 101 in the water discharge mode. In this way, the charge of cold water can be reduced, which is advantageous in that the water in the water storage chamber 101 can be emptied as soon as possible.

For example, in the drain mode, the water intake assembly 30 is switched to the second state after being maintained in the first state for a period of time, and is switched to the first state after being maintained in the second state for a period of time.

For example, the water inlet assembly 30 is configured to switch to the second state when the detection result of the first temperature detecting assembly 20 is less than or equal to the second set temperature; and switches to the first state when the detection result of the first temperature detection component 20 is greater than or equal to the first set temperature, and the second set temperature is less than the first set temperature. In this way, the filling amount of cold water can be reduced, the layer-by-layer drainage is realized, and the water in the water storage cavity 101 can be emptied as soon as possible.

In the state that the detection result of the first temperature detecting component 20 is greater than or equal to the first set temperature, the detection result of the first temperature detecting component 20 may be greater than or equal to the first set temperature, or may be greater than or equal to the first set temperature for a period of time after the detection result of the first temperature detecting component 20 is greater than or equal to the first set temperature; in the state where the detection result of the first temperature detection component 20 is less than or equal to the second set temperature, the detection result of the first temperature detection component 20 may be less than or equal to the second set temperature, or may be less than or equal to the second set temperature for a period of time.

In a specific embodiment, when the water storage cavity 101 needs to be emptied of hot water, the water inlet assembly 30 fills cold water into the bottom of the water storage cavity 101 until the first temperature detection assembly 20 detects that the water temperature of the water at the bottom of the water storage cavity 101 reaches 65 ℃, and the first water outlet 102 is opened; while the water inlet assembly 30 continues to inlet water and reciprocally switches between the first state and the second state (e.g., when the first temperature detection assembly 20 detects that the water temperature of the water at the bottom of the water storage chamber 101 is less than 55 ℃, the water outlet 303 of the water inlet assembly 30 stops introducing cold water into the water storage chamber 101 until the first temperature detection assembly 20 detects that the water temperature of the water at the bottom of the water storage chamber 101 is greater than or equal to 65 ℃, the water outlet 303 of the water inlet assembly 30 is opened to continue to supply water to the water storage chamber 101).

In some embodiments, the first set temperature may be 35 ℃ to 60 ℃ and the second set temperature may be 45 ℃ to 70 ℃.

More specifically, the first set temperature is 45 ℃, and the second set temperature may be 60 ℃.

In some embodiments, as shown in fig. 4, the first water outlet 102 is disposed at the bottom of the water storage cavity 101, the first temperature detecting component 20 is used for detecting the temperature at the bottom of the water storage cavity 101, the water outlet 303 of the water inlet component 30 is disposed at the middle or upper part of the water storage cavity 101, the middle or upper part of the water storage cavity 101 is further provided with the third water outlet 60 and the third temperature detecting component 70, the third water outlet 60 is close to the water outlet 303 of the water inlet component 30 and is used for discharging the water in the water storage cavity 101, and the third temperature detecting component 70 is used for detecting the temperature of the water at the third water outlet 60.

In the water discharge mode, the water outlet 303 of the water inlet assembly 30 is used for introducing cold water into the water storage cavity 101, the third water outlet 60 is used for discharging warm water which is mixed with hot water near the water outlet 303 of the water inlet assembly 30, and the third water outlet 60 is in an open state when the third temperature detection assembly 70 detects that the water temperature near the third water outlet 60 reaches the water temperature capable of being discharged; when the third temperature detecting means 70 detects that the water temperature near the third water outlet 60 does not reach the water temperature that can be discharged, the third water outlet 60 is in a closed state. When the first temperature detecting assembly 20 detects that the water temperature reaches the dischargeable temperature, the first drain opening 102 opens the drain.

Therefore, if the hot water in the water storage cavity 101 is too much, and the water temperature of the water in the water storage cavity 101 cannot be reduced below the dischargeable temperature by filling a large amount of cold water at a time, the water outlet 303 of the water inlet assembly 30 can be firstly enabled to be filled with water, and meanwhile, the third water outlet 60 is enabled to be discharged, so that the cold water can gradually replace the hot water in the water storage cavity 101 and is mixed with the hot water in the water storage cavity 101, the temperature of the water in the whole water storage part 10 is finally reduced below the dischargeable temperature, and finally, the water is discharged from the first water outlet 102 at a time, so that the water temperature of the water discharged by the water storage part 10 cannot be too high.

More specifically, the heating assembly 40 may be an electric heating tube or a heat exchange assembly, and the external high-temperature liquid flows through the heat exchange assembly provided in the water storage chamber 101, so that the water in the water storage chamber 101 can be heated.

In embodiments where the water outlet 303 of the water inlet assembly 30 is located at the bottom of the water storage chamber 101, the water outlet 303 of the water inlet assembly 30 is located toward the bottom wall of the water storage chamber 101 or toward the lower portion of the side wall of the water storage chamber 101, the heating assembly 40 is located at the lower portion of the water storage chamber 101, and the water outlet 303 of the water inlet assembly 30 is located below the heating assembly 40. The heating assembly 40 is located at the lower portion of the water storage chamber 101, which means that the heating assembly 40 is located at a portion of the circumferential side wall of the water storage chamber 101 near the bottom wall and spaced apart from the bottom wall.

Because the water outlet 303 of the water inlet assembly 30 is located at the bottom of the water storage cavity 101, the water outlet 303 of the water inlet assembly 30 faces the bottom wall of the water storage cavity 101 or faces the lower part of the side wall of the water storage cavity 101, so that when the water inlet assembly 30 is used for water inlet, cold water can enter the bottom of the water storage cavity 101 and rise layer by layer without being filled into the upper part of the water storage cavity 101, the heating assembly 40 is located at the lower part of the water storage cavity 101, the water outlet 303 of the water inlet assembly 30 is located below the heating assembly 40, so that the heating assembly 40 can directly heat the cold water filled into the bottom of the water storage cavity 101, the heated cold water is reduced in density, the cold water is higher in density, and the hot water is lower in density after the cold water is continuously filled into the water storage cavity 101, therefore, the cold water can be pushed up to the upper layer by layer, the heating assembly 40 is located in the cold water to heat the cold water, the cold water is heated, the water is reciprocally heated layer by layer, the heating is realized, the heating time of water is reduced, and the heating time is more energy is saved.

When the water inlet assembly 30 is connected with an external directly drinkable water source, cold water is filled into the water storage cavity 101, and the cold water is mixed with hot water in the water storage cavity 101, so that the function of quickly providing warm water can be realized, a user can quickly obtain the warm water, and different use requirements of the user are met.

According to some embodiments of the present invention, in the heating mode, the water inlet assembly 30 is configured to switch between a first state in which water is supplied to the water storage chamber 101 and a second state in which water is stopped from being supplied to the water storage chamber 101. Compared with the heating mode, the water is continuously fed into the water storage cavity 101, and the scheme is beneficial to sufficiently heating the cold water entering the water storage cavity 101.

More specifically, in the heating mode, the water inlet assembly 30 is switched to the second state after being in the first state for a first set time, and is switched to the first state until being in the first set time after being in the second state for a second set time, so that the temperature feedback control process can be reduced.

That is, the water in the water storage chamber 101 is heated to the fourth set temperature, the water inlet assembly 30 re-enters the water, the water inlet assembly 30 enters the water so that the temperature of the water at the bottom of the water storage chamber 101 is reduced to the third set temperature, and the water inlet assembly 30 stops the water inlet. Compared with the mode that water is fed into the water tank for stopping feeding water at intervals, the water tank can reduce the possibility that water is insufficiently heated or the water is excessively heated for too long.

More specifically, the water inlet assembly 30 is configured to switch to the second state after the detection result of the first temperature detecting assembly 20 is continuously less than or equal to the third set temperature for a period of time; the water inlet assembly 30 is configured to switch to the first state after the detection result of the first temperature detecting assembly 20 is continuously greater than or equal to the fourth set temperature for a period of time.

According to some embodiments of the present invention, as shown in fig. 1, the hot water assembly 100 further includes a second temperature detecting assembly 50, the second temperature detecting assembly 50 being used to detect a surface temperature of a heating element of the heating assembly 40. When the second temperature detecting component 50 detects that the surface temperature of the heating element of the heating component 40 is too high, the heating element can be stopped to reduce the possibility of dry heating, which is beneficial to improving the use safety of the hot water component 100 in the embodiment of the invention.
