Abstract
The utility model relates to a refrigerator drawer opening and closing device, which comprises a control unit and a transmission unit controlled by the control unit. The control unit comprises a sensing switch and a control circuit which are connected with a microprocessor, and the sensing switch is arranged on a panel of a refrigerator drawer. The transmission unit comprises a motor connected with the control circuit in the control unit, a guiding rail is arranged on the periphery of the refrigerator drawer, and the motor is connected with a driving device driving the refrigerator drawer to move on the guide rail in output mode. The refrigerator drawer opening and closing device can prevent users from feeling uncomfortable due to frost or low temperature in opening/closing the refrigerator drawer, and the opening/closing of the refrigerator drawer is achieved by the transmission unit, thereby preventing the users from feeling laborious due to weight of the drawer and enabling the users to open/close the refrigerator drawer easily and conveniently.
Description
Technical field
The utility model relates to a kind of refrigerator drawer switching device.
Background technology
In daily life, refrigerator has become the important use equipment of people's life, and people are also increasingly high to the frequency of utilization of refrigerator.In traditional refrigerator, refrigerator drawer is directly to rest the enterprising line slip turnover of dividing plate, needs the user directly to draw back or close with hand during use.Because the article of the modern life are abundant, the food of depositing in the refrigerator is also more and more, and refrigerator drawer is also more and more heavier; Often feel hard inconvenience during pull, particularly in the winter of low temperature, if the panel of refrigerator drawer is provided in a side of in the refrigerator cabinet; The then panel of refrigerator drawer frosting because its surface of low temperature can freeze; People are when pulling, and hand directly touches frost, feels under the weather; If the panel of refrigerator drawer be located at refrigerator doors isoplanar; Article in the common this drawer are more; When people pull out or close refrigerator drawer with the cold metal handle of the firmly tight contact refrigerator drawer of hand, can not feel well equally, and feel painstaking and inconvenient.
The utility model content
The utility model provides a kind of refrigerator drawer switching device, can be when the ON/OFF refrigerator drawer time of human body contact refrigerator drawer very short, can not produce sense of discomfort, and ON/OFF refrigerator drawer that can be easy and convenient.
The refrigerator drawer switching device of the utility model; Include control module and the gear unit that receives said control module control; Wherein in control module, comprise the inductive switch and the control circuit that are connected with microprocessor, wherein inductive switch is located on the panel of refrigerator drawer, gear unit comprise with control module in the motor that is connected of control circuit; On the side face of refrigerator drawer, be provided with guide rail, the output of said motor is connected with and drives the drive unit that refrigerator drawer moves on guide rail.When needs are opened refrigerator drawer; Through human body (like finger) touching inductive switch; The rotation of trigger control circuit control motor, thus make the drive device drives refrigerator drawer protruding, still touch inductive switch when closing through human body (like finger); The reverse rotation of trigger control circuit control motor is inwardly regained the drive device drives refrigerator drawer.Because human body only needs the touching switch is carried out the contact of utmost point short time, therefore can not feel well because of the low temperature of frost or switch itself, accomplish the ON/OFF of refrigerator drawer simultaneously by gear unit, also avoided feeling painstaking because of drawer weight.Wherein inductive switch and control circuit all adopt the module and the technology of present maturation, do not elaborate at this.
More convenient operation in order to use, a kind of preferred mode is inductive switch to be located at the front of refrigerator drawer panel, also can be located at positive and/or at least one side of refrigerator drawer panel as required simultaneously.
In order to make full use of the space in the refrigerator, can motor be located between refrigerator drawer and the refrigerator cabinet.
Further, said guide rail is located at bottom surface and/or two sides of refrigerator drawer, make refrigerator drawer stretch out and advance stressed more even, process is more steady.
A kind of optional scheme is to comprise the fit structure of gear and tooth bar in the drive unit.Make tooth bar do straight reciprocating motion through the motor driven gear rotation, drive the ON/OFF of refrigerator drawer.
Another kind of optional scheme is to comprise the fit structure of worm gear and worm screw in the drive unit.Make worm screw do axial rotation through motor and drive the worm gear rectilinear motion, drive the ON/OFF of refrigerator drawer.
The refrigerator drawer switching device of the utility model; Can when the ON/OFF refrigerator drawer, can not feel well by human body because of frost or the low temperature of itself; And accomplish the ON/OFF of refrigerator drawer by gear unit; Also avoided feeling painstaking because of drawer weight, ON/OFF refrigerator drawer that can be easy and convenient.
Below in conjunction with the specific embodiment, the foregoing of the utility model is remake further detailed description by the accompanying drawing illustrated embodiment.But should this be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following instance.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the utility model.
Description of drawings
Fig. 1 is the connection block diagram of the control module of the utility model refrigerator drawer switching device.
Fig. 2 is a kind of structural representation of the utility model refrigerator drawer switching device user mode.
Fig. 3 is the perspective view of Fig. 2.
The specific embodiment
The refrigerator drawer switching device of the utility model; Include control module and the gear unit that receives said control module control; As shown in Figure 1, wherein in control module, comprise the inductive switch and the control circuit that are connected with microprocessor, you control gear unit work shortly past control circuit for he.Inductive switch and control circuit all adopt the module and the technology of present maturation, do not elaborate at this.
As shown in Figures 2 and 3, the inductive switch 1 of control module is located at the front of refrigerator drawer panel 2, comprise in the gear unit with control module in the motor 3 that is connected of control circuit, motor 3 is located between refrigerator drawer and the refrigerator cabinet.On the two sides of refrigerator drawer, be provided with guide rail 4, the output of motor 3 is connected with and drives the drive unit 5 that refrigerator drawer moves on guide rail 4, and drive unit 5 can be made up of the fit structure of gear and tooth bar.
When needs are opened refrigerator drawer; Through human body (like finger) touching inductive switch 1; 3 rotations of trigger control circuit control motor, thus it is protruding to make drive unit 5 drive refrigerator drawer, still passes through human body (like finger) touching inductive switch 1 when closing; 3 reverse rotations of trigger control circuit control motor make drive unit 5 drive refrigerator drawer and inwardly regain.Because human body only needs touching switch 1 is carried out the contact of utmost point short time, therefore can not feel well because of the low temperature of frost or switch itself, accomplish the ON/OFF of refrigerator drawer simultaneously by gear unit, also avoided feeling painstaking because of drawer weight.
