The refrigerator 100 may generally include: a casing 10 and a plurality of door bodies connected to the front side of the casing 10 for closing a plurality of storage compartments, such as the refrigerated door body 21 and the first freezing door shown in the drawing. Body 22, second freezing door body 23.

The interior of the cabinet 10 defines a storage compartment. The number and structure of the compartments can be configured according to requirements. FIG. 1 shows the case of the first compartment, the second compartment and the third compartment which are arranged one above the other; the upper compartment can be configured as a refrigerating compartment according to the use. , freezing compartment, variable temperature compartment or fresh compartment. Each of the storage compartments may be divided into a plurality of storage areas by a partition panel, and the articles may be stored using a rack or a drawer. The refrigerator 100 of the present embodiment may be a typical French refrigerator, and the three compartments arranged in order from the top to the bottom are a refrigerating compartment, a freezing compartment, and a freezing compartment. Wherein, the opening mode of the refrigerating compartment is a counter door, and the opening mode of the two freezing compartments can be opened by a drawer to realize a drawer type freezing compartment, wherein the drawer rail 237 can ensure the softness of the drawer opening and closing process, and Can reduce noise.

The door body is disposed on the front side of the cabinet 10 for the user to open and close the storage compartment of the refrigerator; the door body can be disposed corresponding to the storage compartment, that is, each storage compartment corresponds to one or more doors body. The number of storage rooms and door bodies, and the function of the storage room can be actually selected by specific circumstances. The refrigerator 100 of the present embodiment is provided with a refrigerating compartment, a freezing compartment, and a freezing compartment which are provided in this order, and is provided with a refrigerating door body 21, a first freezing door body 22, and a second freezing door body 23, respectively.

In this embodiment, at least the door body of the freezing compartment can be automatically opened by touch, and the touch can be realized by using a capacitive touch technology. Capacitive touch technology works with the current sensing of the human body. When the user's finger touches the conductive electrode plate, the user and the surface of the conductive electrode plate form a coupling capacitance due to the human body electric field. Specifically, when the user touches the conductive electrode plate, a coupling capacitance is generated between the finger and the conductive electrode plate; when the finger is removed, the coupling capacitance disappears, and the user can be judged by detecting the capacitance value. The automatic opening of the door of the refrigerator 100 of this embodiment is realized based on this principle.

The above-mentioned touch mode can be applied to the door body assist of each storage compartment, wherein since the second freezing compartment of the refrigerator 100 is at the bottom and the position is low, the child can easily touch the second freezing door body 23 during play. The second freezing door body 23 is automatically opened, causing leakage of the freezing compartment and affecting the freezing effect of the articles stored in the refrigerator 100.

Therefore, in the present application, the judgment of the use of the capacitive touch technology to assist in opening the door is optimized, and is preferentially applied to the second freezing door body 23.

FIG. 8 is a schematic block diagram of a refrigerator 100 in accordance with one embodiment of the present invention. In some embodiments of the present invention, the refrigerator 100 may further include a plurality of conductive plates 233, a capacitance detecting portion 234, and a door assisting device 230.

Wherein, the preset area may be each door of the refrigerator 100 The inside of the handle bar 232 is convenient for the user to operate when the door is opened, in accordance with the user's operating habits. For example, a plurality of conductive plates 233 may be disposed inside the trim 232 of the handle of the second freezing door body 23, which can more effectively prevent the door of the refrigerator from being automatically opened due to accidental touch by children. The trim strip 232 serves as an insulating layer and a protective layer on the outside of the conductive electrode plate 233. In some embodiments, a third layer of non-conductive glass layer, a conductive layer of the fourth layer, and a conductive layer of the fourth layer as a shielding layer may be disposed at the rear of the conductive plate 233 to shield internal electrical signals.

In some embodiments, a plurality of decorative strips 232 may be disposed on the handle of the door body, and each of the decorative strips 232 is internally provided with a conductive electrode plate 233. In other embodiments, the handle is arranged with a predetermined length of trim 232 along its length, and the plurality of conductive plates 233 are spaced apart along the trim 232. Specifically, the trim strip 232 may be divided into a plurality of portions by a notch, and each of the decorative strips may have a conductive electrode plate 233 inside thereof; or a portion of the trim strip 232 may be arranged with a plurality of conductive electrode plates 233 at intervals. Both settings can be used to detect the coupling capacitance of multiple conductive plates inside a door handle. When the plurality of conductive plates 233 are disposed on the second freezing door body 23, a plurality of decorative strips 232 may be disposed on the handle of the second freezing door body 23, and each of the decorative strips 232 is internally provided with a conductive plate 233. Alternatively, a decorative strip 232 of a predetermined length is disposed along the longitudinal direction of the handle of the second freezing door body 23, and the plurality of conductive plates 233 are spaced apart along the trim strip 232. Specifically, since the handles of the second freezing door body 23 are generally disposed laterally, the plurality of conductive plate plates 233 may be disposed at intervals in the horizontal direction.

And the time difference between the two conductive plates forming the coupling capacitor is 0.2 second. If the timing of the coupling capacitance between the conductive plate "1" and the conductive electrode plate "2" is the first conductive electrode plate "1", the conductive electrode plate "2" After that, and the time when the coupling capacitor is formed is less than 0.2 second, it is considered to meet the preset door opening condition.

For example, the inside of the trim 232 of the handle of the second freezing door body 23 is provided with a conductive plate "1", a conductive plate "2", and a conductive plate "3". The preset door opening condition is that the user is guided by the conductive plate. "1" slides through the conductive plate "2" and the conductive plate "3" in turn, and sets the time difference between the two adjacent conductive plates to form a coupling capacitance of 0.2 seconds. If the three conductive plates form a coupling If the timing and time difference of the capacitor meet the above conditions, the booster of the door can be driven to open. At this time, the user's operation is from top to bottom, or from left to right along the door trim strip. The specific operation mode can be set according to the arrangement of the trim strip and the conductive plate.

Moreover, as shown in FIG. 2, the motor 235 and the transmission 236 may be disposed at the bottom of the second freezing compartment, and the transmission 236 may be a transmission rod. When the motor 235 is rotated at a preset speed, the transmission 236 is at a corresponding speed. The second freezing compartment door body 23 is opened. The preset specific speed value can be obtained based on the results of many experiments, to avoid the drawer opening speed hitting the user too fast, affecting the user experience.

In addition, the refrigerator 100 may further include a display device, and the display device may be disposed on a surface of the door body of the refrigerator 100 for acquiring a pre-configured door body touch option, and the door touch option is configured to enable the anti-missing function. In the case, a step of judging whether or not the preset door opening condition is met is performed. In the case where the door touch option is configured to turn off the anti-missing function, when any one of the plurality of conductive plates 233 is detected to be coupled, the boosting device that drives the door is activated. The anti-missing function can more effectively prevent children from unintentionally opening the door of the refrigerator during play to avoid danger.

In the refrigerator 100 of the embodiment, a plurality of conductive plates 233 are disposed in a predetermined area of the door body to form a coupling capacitance when the user touches the human body, and the coupling capacitance of the plurality of conductive plates 233 is detected.

In the case of the opening condition, when the door touch option is configured to turn off the anti-missing function, when the coupling capacitance is detected in any one of the plurality of conductive plates, the boosting device that drives the door body is activated, and two types are provided. Different refrigerator door opening methods allow users to select according to actual needs, effectively improving the user experience.

In the above steps, the formation of the coupling capacitor in step S602 is related to the current sensing of the human body. When the user's finger touches the conductive electrode plate 233, the user's finger and the surface of the conductive electrode plate 233 form a coupling capacitance due to the human body electric field. Specifically, when the user's finger touches the conductive plate 233, a coupling capacitance is formed; when the finger is removed, the coupling capacitance disappears, and the user can be judged by detecting the capacitance.

The preset door opening condition in step S604 can be obtained according to a plurality of experimental results, and the timing of forming the coupling capacitor and/or the formation time difference are set in advance, so that the door body can be prevented from being accidentally opened more effectively. For example, the time difference formed by the coupling capacitance of the two conductive plates is set to 0.2 second.
