Problems solved by technology

However, this traditional electric kettle has the following disadvantages: it can only control a certain temperature point of the electric kettle, and cannot control the temperature heated by water at multiple points
But at present this type of electric kettle needs to be installed with a relay or a thyristor, which leads to an increase in the price and cost of the electric kettle; because the power switch of the existing adjustable temperature electric kettle is all in the form of a button, so that there is no Set the power switch handle, so it is very inconvenient for some customers who are used to the traditional pressing method

specific Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown, it is the first embodiment in the present invention. Such as figure 1 As shown, the present embodiment mainly includes a kettle body 1 and a base 2 . The kettle body 1 is provided with an NTC thermistor, a heating device 5, a switch device and a PCB board 6, the heating device 5 divides the kettle body 1 into two spaces up and down, and the NTC thermistor is arranged on The upper space detects the temperature of water (the NTC thermistor can also be arranged at the bottom of the heating device, thereby judging the temperature of the heating water. The setting method of the NTC thermistor is, in the electric kettle for electronic water temperature measurement, Prior art.), the switchgear and the PCB board 6 are all arranged in the lower space, and the NTC thermistor generally adopts NTC negative temperature coefficient thermistor. Described switch gear comprises electromagnetic switch 3 and driving mechanis...

specific Embodiment 2

[0040] Compared with the solution in the first embodiment, the main difference of this embodiment is that a new electromagnet switch is provided, so this embodiment will further introduce this electromagnet switch in detail, and the installation and setting method of the electromagnet switch Can refer to the appendix in the first embodiment figure 1 .

[0041] Such as Figure 5 As shown, the electromagnetic switch 3 includes a base 301, a bracket 3011, an armature bracket 3021, and an electromagnetic coil 3024. The electromagnetic coil 3024 and the bracket 3011 are all fixedly arranged on the base 301, and the armature bracket 3021 One end of the coil is rotated on the top of the bracket 3011 through a pin, and the armature bracket 3021 is fixedly installed with an armature 3022, and the electromagnetic coil 3024 can generate magnetic force to attract the armature 3022 after being energized. Regarding the working principle of the electromagnet switch 3 , reference may also b...

specific Embodiment 3

[0046] Compared with the solution in the second embodiment, the main difference of this embodiment is that a mechanism for separating the first conductive terminal 3041 and the second conductive terminal 3042 from each other is added to the electromagnet switch 3 during dry burning, so in This mechanism will be described in further detail in this embodiment.

[0047] Such as Figure 8 , Figure 9 , Figure 10 As shown, the mechanism includes a temperature sensor 7 and a driving rod 701 matched therewith. In this embodiment, the temperature sensor 7 is a bimetal strip temperature sensor, and the temperature sensor 7 is fixed on the base 301 . The base 301 is provided with a through hole 3013 concentric with the positioning hole 3012 , and one end of the driving rod 701 is in contact with the edge of the temperature sensor 7 . The other end of the drive rod 701 passes through the through hole 3013 and is in contact with the boss 3027 on the inverted trapezoidal block 3026 (t...

Abstract

The invention discloses an electric kettle, aiming at providing the electric kettle which is capable of regulating and controlling heating temperature of water and has low cost and convenient operation. The invention adopts the technical scheme that the electric kettle comprises a kettle body (1), an NTC (Negative Temperature Coefficient) thermistor, a heating device (5) and a PCB (6), wherein the kettle body (1) is divided into an upper space and a lower space by the heating device (5); the electric kettle also comprises an electromagnetic switch (3) and a driving mechanism (4) which are arranged in the lower space; one end of the drive mechanism corresponds to an armature bracket (3021) in the electromagnetic switch (3) at the space position; the other end of the driving mechanism (4) extends out of the side wall of the kettle body (1); and the on / off of two pairs of contact switches can be controlled by the on / off of the electromagnetic switch. The invention can be widely applied to the field of electric kettles capable of regulating and controlling the heating temperature of water.

Description

technical field [0001] The invention relates to an electric kettle, in particular to an electric kettle with adjustable water heating temperature. Background technique [0002] At present, electric kettles have become small household appliances widely used in ordinary families and units. Traditional electric kettles are generally provided with temperature sensors with bimetallic strips. Its working principle is: add an appropriate amount of water to the electric kettle, and then put the electric kettle on the power base; the user presses the power switch handle of the electric kettle, the electric kettle is connected to the power supply, and the heating device starts to heat the water; the water is heated and boiled. When boiling, the bimetal temperature sensor is deformed due to the rise to the boiling temperature, and then the switch reed is driven by the sudden jump of the bimetal deformation, so that the switch is disconnected, the power supply of the electric kettle is...
