DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A precise temperature-controlled intelligent electric kettle comprises a kettle body 1, a base 2 and a handle 3. The kettle body 1 is fixedly mounted on the top of the base 2, the handle 3 is fixedly mounted on one side of the kettle body 1, one side of the kettle body 1 is movably connected with a kettle cover 4 via a hinge, one side of the kettle body 1 is fixedly connected with a water outlet 5, one side of the kettle body 1 is fixedly mounted with a PLC controller 6, and a temperature control mechanism is arranged inside the kettle body 1 to control the water temperature in the kettle body 1.

[0028] The temperature control mechanism comprises a heating chamber 7 opened inside the base 2, an electric heating rod 8 is fixedly installed at the bottom of the heating chamber 7, a heat conducting plate 9 is fixedly connected to the surface of the electric heating rod 8, a heat conducting rod 10 is fixedly connected to the top of the heat conducting plate 9, one end of the heat conducting rod 10 penetrates into the interior of the kettle body 1, a temperature sensor 11 is fixedly installed on the inner wall of the kettle body 1, a flow hole 12 is opened on the top of the kettle cover 4, and the number of the flow holes 12 is several. A heat dissipation mechanism is arranged on the top of the kettle cover 4, which can dissipate the water in the kettle body 1, thereby improving the temperature control effect of the temperature control mechanism;

[0029] In this embodiment, by setting a temperature control mechanism, when a user uses the electric kettle to boil water, the PLC module built in the PLC controller 6 in the temperature control mechanism can be used to start the electric heating rod 8, and the heat is transmitted to the heat conducting plate 9 by the heat heating rod 8, and then the heat conducting plate 9 transmits the heat conducting rod 10, and the water in the kettle body 1 is heated by the heat conducting rod 10. Since the heat conducting rod 10 and the heat conducting plate 9 are made of copper, the heat conducting effect is better, which further improves the heating efficiency of the temperature control mechanism, and the number of the heat conducting rods 10 is several, which greatly increases the heat conducting area, so that the water in the kettle body 1 is heated faster, and the heat insulation ring 20 better protects the user from being scalded when touching the bottom of the kettle body 1, and further improves the heating effect of the temperature control mechanism. When the water boils, the boiling temperature of the water can be sensed by the temperature sensor 11 in the kettle body 1, and then the signal is transmitted to the PLC controller 6, and the power supply is disconnected by the PLC controller 6, so as to achieve the temperature control effect;

[0030] The invention solves the problem that most electric kettles on the market currently do not have the function of controlling the temperature inside the kettle. When the water boils, the user needs to manually turn off the kettle switch, which is very inconvenient to use. If the water power is not turned off in time, the water will splash out after boiling, which may cause burns, electric shock and short circuit, posing a huge safety hazard.

[0031] The number of heat conducting rods 10 is several and evenly distributed on the surface of the heat conducting plate 9;

[0032] By setting the number of heat-conducting rods 10 to be several and evenly distributed on the surface of the heat-conducting plate 9, the heat-conducting area can be greatly increased, so that the water in the kettle body 1 can be heated faster and more efficiently, further improving the heating effect of the temperature control mechanism.

[0033] The heat conducting rod 10 and the heat conducting plate 9 are made of copper;

[0034] By setting the material of the heat conducting rod 10 and the heat conducting plate 9 to be copper, when the PLC controller 6 starts the electric heating rod 8 to heat the water in the kettle body 1, the heating area can be increased, the heating effect is better, and the heating efficiency of the temperature control mechanism is further improved.

[0035] The inner wall of the heating chamber 7 is fixedly mounted with a heat insulating ring 20, and the material of the heat insulating ring 20 is rock wool;

[0036] By setting the heat insulating ring 20 and making the heat insulating ring 20 of rock wool, it is possible to prevent the user from touching the bottom of the kettle body 1 when pouring water using the kettle body 1 and being scalded due to the high temperature of the bottom of the kettle body 1.

[0037] Embodiment 2:

[0038] On the basis of the first embodiment, the temperature control mechanism in the first embodiment can control the temperature of the water in the kettle body 1, but does not have the function of accurately controlling the water temperature in the kettle body 1. When the user wants to drink water below the boiling temperature, he can only wait for the water in the kettle body 1 to cool naturally, which causes great inconvenience to the user, thereby reducing the temperature control effect of the temperature control mechanism and the practicality of this device. The heat dissipation mechanism in the present application includes a storage box 13 fixedly arranged on the top of the kettle cover 4, one side of the storage box 13 is fixedly connected with a flow pipe 14, one end of the flow pipe 14 passes through the interior of the kettle body 1, the inner wall of the storage box 13 is fixedly connected with a fixing plate 15, one side of the fixing plate 15 is fixedly installed with a motor 16, the output end of the motor 16 is fixedly connected with a connecting rod 17, one end of the connecting rod 17 is fixedly connected with a rotating block 18, and three fan blades 19 are fixedly installed on the surface of the rotating block 18;

[0039] In this embodiment, by providing a heat dissipation mechanism, when the user uses the temperature control mechanism to boil water but wants to drink water below the boiling temperature, the motor 16 in the heat dissipation mechanism can be started through the built-in PLC module of the PLC controller 6. The rotation of the motor 16 drives the connecting rod 17 in the storage box 13 to rotate, and at the same time drives the rotating block 18 and the fan blades 19 to rotate. The wind force generated by the rotation of the fan blades 19 flows into the kettle body 1 through the flow pipe 14, thereby cooling the water in the kettle body 1. At the same time, the hot air in the kettle body 1 flows out through the flow hole 12 and the heat dissipation port 21, further improving the heat dissipation effect. When the temperature in the kettle body 1 drops to the temperature required by the user, the temperature sensor 11 will sense and transmit the signal to the PLC controller 6. After the motor 16 is turned off by the built-in PLC module of the PLC controller 6, the user can drink as much as he wants, thereby achieving the effect of precise temperature control.

[0040] It should be noted that the motor 16, the electric heating rod 8 and the temperature sensor 11 are connected to the PLC controller 6 by telecommunication;

[0041] The problem that the temperature control mechanism does not have the function of accurately controlling the water temperature in the kettle body 1 is solved. When the user wants to drink water below the boiling water temperature, he can only wait for the water in the kettle body 1 to cool naturally, which causes great inconvenience to the user, thereby reducing the temperature control effect of the temperature control mechanism and the practicality of the device.

[0042] A heat dissipation port 21 is provided on one side of the storage box 13, and a filter plate 22 is fixedly installed inside the heat dissipation port 21;

[0043] By providing the heat dissipation port 21 and the filter plate 22, the wind force generated when the fan blades 19 rotate can flow into the interior of the kettle body 1 through the circulation tube 14, thereby cooling the water inside the kettle body 1. The filter plate 22 prevents dust and impurities from entering the storage box 13 inside the machine, thereby preventing the heat dissipation effect of the heat dissipation mechanism from being affected.

[0044] Working principle: when the user uses the electric kettle to boil water, the PLC module built into the PLC controller 6 in the temperature control mechanism can be used to start the electric heating rod 8, and the heat is transmitted to the heat-conducting plate 9 through the heat-conducting plate 9, and then the heat-conducting rod 10 is transmitted through the heat-conducting plate 9, and the water in the kettle body 1 is heated by the heat-conducting rod 10. Since the heat-conducting rod 10 and the heat-conducting plate 9 are both made of copper, the heat-conducting effect is better, which further improves the heating efficiency of the temperature control mechanism, and the number of heat-conducting rods 10 is several, which greatly increases the heat-conducting area, so that the water in the kettle body 1 is heated faster, and the heat insulation ring 20 better protects the user from being scalded when touching the bottom of the kettle body 1, further improving the heating effect of the temperature control mechanism. When the water boils, the boiling temperature of the water can be sensed by the temperature sensor 11 in the kettle body 1, and then the signal is transmitted to the PLC controller 6, and the power supply is disconnected by the PLC controller 6, thereby achieving the temperature control effect;

[0045] When the user uses the temperature control mechanism to boil water but wants to drink water at a temperature lower than boiling water, the user can start the motor 16 in the heat dissipation mechanism through the built-in PLC module of the PLC controller 6. The rotation of the motor 16 drives the connecting rod 17 in the storage box 13 to rotate, and at the same time drives the rotating block 18 and the fan blades 19 to rotate. The wind force generated by the rotation of the fan blades 19 flows into the kettle body 1 through the circulation tube 14, thereby cooling the water in the kettle body 1. At the same time, the hot air in the kettle body 1 flows out through the circulation hole 12 and the heat dissipation port 21, further improving the heat dissipation effect. When the temperature in the kettle body 1 drops to the temperature required by the user, the temperature sensor 11 will transmit a signal to the PLC controller 6. After the motor 16 is turned off by the built-in PLC module of the PLC controller 6, the user can drink as much as he wants.

[0046] It should be noted that the motor 16, PLC controller 6, temperature sensor 11, electric heating rod 8, thermally conductive rod 10 and thermal insulation ring 20 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. The specific composition and principle of the power supply of the motor 16, PLC controller 6, temperature sensor 11, electric heating rod 8, thermally conductive rod 10 and thermal insulation ring 20 are clear to those skilled in the art, so they will not be described in detail.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
