[0006] As a further improvement, the inner top surface of the second inner tank is lower than the inner top surface of the main inner tank, so that part of the water in the inner cavity of the main inner tank can more easily flow back into the water containing cavity.

[0007] As a further improvement, a baffle is provided around one end of the water inlet pipe entering the inner cavity of the main inner tank, and the baffle prevents the water from flowing directly upward when the water inlet pipe is filled with water, so as to prevent unboiled water from being discharged from the water outlet pipe.

[0008] As a further improvement, a temperature sensor is provided in the main inner tank, and when the temperature sensor detects that the water temperature reaches 100°C, the controller cuts off the power supply of the electric heater, thereby preventing the water from over-boiling, ensuring the quality of the boiled water, and saving electricity.

[0009] Furthermore, the electric heater is installed on the lower end surface of the main inner tank to prevent scale from adhering to the electric heater; an over-temperature protector is provided at the bottom of the main inner tank, and when the over-temperature protector detects that the temperature of the inner tank exceeds the set temperature, the power supply of the electric heater is cut off through the controller to prevent the main inner tank from dry burning.

[0010] Furthermore, it also includes a shell, the main liner and the second liner are installed in the shell, and the controller is installed on the shell, so as to improve the aesthetics and better protect the main liner and the second liner.

In this way, when water is taken in, the water in the water holding chamber is sucked into the inner cavity of the main inner liner through the siphon effect, and the lower part of the bag body will shrink upward. When water comes out of the water outlet pipe, it means that the inner cavity of the main inner liner is full of water.

In this case, when the electric heater is powered on for heating and the water is heated to 100°C and boils, since a part of the space in the upper part of the inner cavity of the main inner liner is vacated without water, this part of the space can absorb the expanded water, thereby preventing high-temperature water droplets from overflowing from the water outlet of the water outlet pipe, thereby improving the safety of use.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Embodiment 1 Figures 1 to 4 As shown, a water boiler with an open water outlet includes a housing 1, a water inlet pipe 2, a water outlet pipe 3, a main inner tank 4, a controller 5 and an electric heater 6. The water outlet pipe 3 is connected to the upper part of the inner cavity of the main inner tank 4. The electric heater 6 is installed on the lower end surface of the main inner tank 4 to indirectly heat water to prevent scale from adhering to the electric heater 6. As another way, the electric heater 6 can also penetrate into the inner cavity of the main inner tank 4 to contact with the water and directly heat it. The water inlet pipe 2 penetrates into the inner cavity of the main inner tank 4 from the side of the main inner tank 4 and is connected to the lower part of the inner cavity of the main inner tank 4. A second inner tank 7 is provided next to the main inner tank 4, and a The deformable bag body 8, the outer surface of the deformable bag body 8 is connected to the atmosphere, the inner wall of the second liner 7 and the inner wall of the deformable bag body 8 form a water accommodating chamber 80, the water accommodating chamber 80 is connected to the water inlet pipe 2, and the water inlet pipe 2 is provided with a siphon hole 20, through which the water in the water accommodating chamber 80 can be sucked into the inner cavity of the main liner 4 when the water inlet pipe 2 is inflowing, the bottom of the second liner 7 is lower than the top of the main liner 4, so that the water in the main liner 4 can partially flow back into the water accommodating chamber 80 when the water inlet pipe 2 is not inflowing; the water inlet pipe 2 controls the water inflow through a gate valve; the inner top surface of the second liner 7 is lower than the inner top surface of the main liner 4. The working principle of the siphon hole 20 refers to the conventional Venturi effect.

[0025] The water inlet pipe 2 includes a first vertical section 21 and a second vertical section 22, the first vertical section 21 and the second vertical section 22 are connected by a transverse section 23, the first vertical section 21 is outside the main inner tank 4, the second vertical section 22 is inside the main inner tank 4, the water accommodating chamber 80 is connected to the transverse section 23 of the water inlet pipe 2 through a vertical channel 81, the siphon hole 20 is arranged at the connection between the transverse section 23 and the first vertical section 21, and the upper end of the vertical channel 81 is close to the water outlet side of the siphon hole 20. The water inlet pipe 2 can be formed by multiple sections of sleeve connection.

[0026] A baffle 24 is provided around one end of the water inlet pipe 2 entering the inner cavity of the main inner tank 4, that is, a baffle 24 is provided around the lower end of the second vertical section 22. When water enters the water inlet pipe 2, the baffle 24 prevents the incoming water from flowing directly upward, thereby preventing unboiled water from being discharged from the water outlet pipe 3.

[0027] The main inner tank 4 is provided with a temperature sensor 41. When the temperature sensor 41 detects that the water temperature reaches 100°C, the controller 5 cuts off the power supply of the electric heater 6. This prevents the water in the inner cavity of the main inner tank 4 from boiling for a long time, which not only reduces the quality of the water, but also consumes energy.

[0028] An over-temperature protector 42 is installed at the bottom of the main inner tank 4. When the over-temperature protector 42 detects that the temperature of the inner tank exceeds the set temperature, the controller 5 cuts off the power supply of the electric heater 6 to avoid dry burning damage to the main inner tank 4.

[0029] The main inner pot 4 and the second inner pot 7 are installed in the shell 1 , and the controller 5 is installed on the shell 1 .

[0030] The water inlet end of the water inlet pipe 2 is provided with a quick connector 25 to facilitate connection with an external water inlet pipe.

[0031] The main liner 4 is made of stainless steel, and a heat-insulating layer 43 is provided around the main liner 4. The second liner 7 can be an injection molded part or a stamped part, and a plurality of through holes 71 are provided at the bottom of the second liner 7, so that the outer surface of the deformable bag body 8 is connected to the atmosphere through the plurality of through holes 71. The bag body 8 can be made of rubber material.

[0032] When this embodiment is used, the first time water is added, the gate valve is opened, and water is added to the main inner chamber 4 through the water inlet pipe 2. At this time, since there is no water in the water accommodating chamber 80, part of the air in the water accommodating chamber 80 will be drawn out through the siphon effect of the siphon hole 20, and the lower part of the bag body 8 will shrink upward, and a certain degree of vacuum will appear in the water accommodating chamber 80. When water comes out of the water outlet pipe 3, it means that the main inner chamber 4 is filled with water, and then the water inlet pipe 2 is closed to control the gate valve to stop water inlet. At this time, under the combined effect of atmospheric pressure, water gravity and the rebound of the bag body 8, part of the water in the inner chamber of the main inner chamber 4 flows into the water accommodating chamber 80, so that a part of the space in the upper part of the inner chamber of the main inner chamber 4 is free of water. In this case, the electric heater 6 is powered on for heating, and the heating is stopped when the water is heated to 100°C and boils. Since a part of the space in the upper part of the inner chamber of the main inner chamber 4 is free of water, this part of the space can absorb the expanded water and prevent high-temperature water droplets from overflowing from the outlet of the water outlet pipe 3. Improve the safety of use.

[0033] When boiling water is needed, the gate valve is opened again, and water is introduced from the water inlet pipe 2 into the lower part of the inner cavity of the main inner tank 4. During the water inlet process, due to the siphon effect of the siphon hole 20, part of the water in the water containing chamber 80 will be sucked into the inner cavity of the main inner tank 4. After the water inlet fills the inner cavity of the main inner tank 4, the boiled water in the upper part of the inner cavity of the main inner tank 4 can be output from the water outlet pipe 3. After the water is taken, the gate valve is closed again. At this time, under the combined effect of atmospheric pressure, water gravity and the rebound of the bag body 8, part of the water in the inner cavity of the main inner tank 4 flows back into the water containing chamber 80, and a part of the space in the upper part of the inner cavity of the main inner tank 4 is vacated without water. This is convenient for preventing high-temperature water droplets from overflowing from the outlet of the water outlet pipe 3 when heating water later. It is cyclically used in this way.

[0034] Embodiment 2 Figures 5 to 7 As shown, a water boiler with an open water outlet is provided, which is different from the first embodiment in that a connecting external thread 26 is provided at the water inlet end of the water inlet pipe 2, and is connected to an external water inlet pipe through the connecting external thread 26; the shapes of the housing 1 and the controller 5 are also different.

[0035] The working principle of this embodiment is the same as that of the first embodiment.

[0036] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
