Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1-4 schematically show a coffee maker according to some embodiments of the present invention, comprising a body 1, a cooking section 2, a capacitive sensor 4 and an electromagnetic shield 3.
The body 1 is a hollow shell. In some embodiments, a depression 11 is formed on an outer side surface of the body 1 for placing the cooking part 2. The fuselage 1 may be made of metal, plastic or other material.
The cooking unit 2 is used for cooking coffee, and can be placed in the main body 1 to heat the coffee in the cooking unit 2 through the main body 1. In some embodiments, the cooking section 2 may heat the coffee by electromagnetic heating. The cooking part 2 can be designed into a kettle shape and can be taken out of the machine body 1, thereby being convenient for use. The cooking part 2 may be made of metal, plastic, glass or other materials.
The capacitive sensor 4 is disposed on the sidewall of the body 1, corresponds to the height range of the liquid level of the cooking unit 2, and detects the liquid level of the cooking unit 2, which is the height position of the liquid or the foam. In some embodiments, the capacitive sensor 4 is vertically disposed so as to be able to cover a maximum liquid level height range. The capacitive sensor 4 may be provided on an inner side wall of the body 1 to facilitate installation and connection with other circuitry or wiring within the body 1. The capacitive sensor 4 is preferably disposed on the inner sidewall of the body 1 where the recess 11 is located, so as to be closer to the cooking part 2, so that the detection result is more accurate. At least one capacitive sensor 4 may be provided, or two or more capacitive sensors may be provided, in this embodiment, two capacitive sensors are provided side by side. In some implementations, the capacitive sensor 4 employs FDC 2212.
The electromagnetic shield 3 at least partially covers the capacitive sensor 4, thereby shielding electromagnetic wave interference in the surrounding environment and thus improving the accuracy of the capacitive sensor 4. This is because the capacitive sensor 4 has high sensitivity, interference of electromagnetic waves in its surrounding environment may affect the operation of the capacitive sensor 4, resulting in a reduction in its detection accuracy, and by providing the electromagnetic shield 3 around the capacitive sensor 4, an unexpected situation due to interference of electromagnetic waves can be prevented, so that the liquid level inside the cooking part 2 can be accurately measured.
In some embodiments, the electromagnetic shield 3 may include side plates 32 for covering the sides of the capacitive sensor 4, may also include a top plate 31 for covering the top of the capacitive sensor 4, and may also include a bottom plate for covering the bottom of the capacitive sensor 4 in other embodiments. The top plate 31 and the side plate 32 are connected to each other and are respectively connected to the inner side wall of the body 1 to form a shape of a protective cover, which may be a flat plate or an arc plate with an arc surface. In the present embodiment, the side plates 32 include at least three flat plates arranged in a vertical direction, the three flat plates are connected in a right angle manner, and the flat plates at both sides are respectively connected to the inner side walls of the body 1. The top plate 31 is a flat plate horizontally arranged and closes the top ends of the side plates 32.
The electromagnetic shield 3 may cover the capacitive sensor partially or completely, and the capacitive sensor may be wired to other circuit devices, such as a microprocessor, by drilling a hole in the electromagnetic shield 3.
The electromagnetic shielding member 3 may be made of metal, or may be made of other materials with electromagnetic shielding function, or may be formed by coating a material coating with electromagnetic shielding function on a substrate, or the like.
The utility model discloses a coffee machine improves coffee machine's liquid level detection precision through the capacitive sensor 4 that sets up high sensitivity, is provided with electromagnetic shield 3 simultaneously in order to prevent the interference of the electromagnetic wave in the environment to capacitive sensor 4 to can improve the liquid level detection degree of accuracy, effectively judge the state of cooking of coffee.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, or the above technical solutions can be freely combined, including the technical features between the above different embodiments, which all belong to the protection scope of the present invention.
