A refrigerator, as shown in fig. 2 and 3, comprising a storage box body 1 and a drawer door assembly 2 slidably connected to the storage box body 1, wherein the drawer door assembly 2 comprises a drawer door panel 21 and a storage part 22 fixedly connected with the drawer door panel; the storage part 22 is connected with the storage box body 1 through a slide rail 3; the refrigerator further includes: the driving device 4 is in driving connection with the storage part 22 and is used for driving the storage part 22 to slide along the sliding rail 3 so as to open or close the drawer door assembly 2; the obstacle sensor 5 is used for detecting whether an obstacle exists within a preset distance in the movement direction of the drawer door assembly 2; the controller 6 is electrically connected with the driving device 4, and the obstacle sensor 5 is electrically connected with the controller 6; when the obstacle sensor 5 detects that an obstacle exists within a preset distance in the movement direction of the drawer door assembly 2, the controller 6 controls the driving device 4 to stop; when the obstacle sensor 5 detects that there is no obstacle within a preset distance in the moving direction of the drawer door assembly 2, the controller 6 controls the driving device 4 to be activated.
As shown in fig. 2 and 3, the refrigerator according to the embodiment of the present invention includes a driving device 4, an obstacle sensor 5, and a controller 6, wherein the driving device 4 and the obstacle sensor 5 are electrically connected to the controller 6, and the driving device 4 can make the drawer door assembly 2 perform opening or closing movement with respect to the storage box 1 through different operation modes; the obstacle sensor 5 is used for detecting whether an obstacle exists within a preset distance in the movement direction of the drawer door assembly 2, and transmitting the detection information to the controller 6 or extracting the detection information from the obstacle sensor 5 by the controller 6; the controller 6 is configured to receive user operation command information and collision information and control the operation of the driving device 4 according to different combinations of information, so as to allow the drawer door assembly 2 to perform an opening or closing motion with respect to the storage compartment 1. Compared with the prior art, when there is the barrier in the predetermined distance in the direction of motion of drawer door subassembly 2, barrier inductor 5 detects that there is the barrier in the predetermined distance in the direction of motion of drawer door subassembly 2 to with the above-mentioned detection information transfer that has the barrier for controller 6 or by controller 6 draws from barrier inductor 5 in, at this moment, controller 6 control drive arrangement 4 stop motion, prevent that drawer door subassembly 2 from colliding with the barrier, thereby avoid personnel's injury, article are impaired or refrigerator drawer door subassembly 2 damages because of the collision.
It should be noted that, in the process from the obstacle sensor 5 sensing that an obstacle exists within the preset distance in the moving direction to the controller 6 receiving the detection information that an obstacle exists and controlling the driving device 4 to stop, the drawer door assembly 2 still moves, so to avoid the drawer door assembly 2 colliding with an obstacle in the process, the preset distance should be greater than or equal to the distance that the drawer door assembly 2 moves in the process, and generally, the preset distance is 5cm to 30cm according to the moving speed of the drawer door assembly 2 and the time of the process.
It can be understood that the above-mentioned action of automatically opening or closing the drawer door assembly 2 is determined by the requirement of the user, and therefore, as shown in fig. 2 and 3, the refrigerator according to the embodiment of the present invention further includes an instruction input unit 7, wherein the instruction input unit 7 is electrically coupled to the controller 6 for receiving the user input operation instructions to the controller 6, and the operation instructions at least include an instruction for controlling the drawer door assembly 2 to automatically open and an instruction for controlling the drawer door assembly 2 to automatically close. The instruction input unit 7 may be one or more of a touch sensing input, a voice input, a vibration input, and a character code graphic input according to input information different from the user. Generally, the refrigerator at least comprises a refrigerating chamber and a freezing chamber, the instruction input unit can be arranged on the refrigerating door body 8 or on the drawer door panel 21, when the instruction input unit 7 is arranged on the drawer door panel 21, a user needs to bend down or crouch down to send an operation instruction, and the use is inconvenient, so that the instruction input unit 7 is arranged on the refrigerating door body 8, as shown in fig. 2, and the instruction input unit 7 is usually positioned right ahead when the user stands, so that the user can conveniently operate. In addition, in order to ensure the convenience and reliability of functional use, the refrigerator of the embodiment of the invention adopts two input combinations of sound input and touch induction input, wherein the touch induction input is specifically a sliding key 71, and the sliding key 71 is arranged at the lower part of the freezing door body 8, so that the manual touch operation of a user is facilitated; the voice input is a voice input module 72, and the voice input module 72 is arranged at the upper part of the freezing door body 8, is usually at the same height with the head of an adult user, and is convenient for receiving the voice input of the user. At this time, taking the sliding button 71 control as an example, the user operates the sliding button 71 to send information for opening the drawer door assembly 2 to the controller 6, and the controller 6 determines whether the drawer door assembly 2 performs an automatic opening operation according to the detection information of the obstacle sensor 5; the user operates the slide button 71 to send information for closing the drawer door assembly 2 to the controller 6, and the controller 6 determines whether the drawer door assembly 2 is automatically opened or not according to the detection information of the obstacle sensor 5.
When the obstacle sensor 5 detects that an obstacle exists in the preset distance in the moving direction of the drawer door assembly 2, the controller 6 controls the driving device 4 to stop moving to prevent the refrigerator drawer door assembly 2 from colliding with the obstacle, and at this time, in order to remind a user that the obstacle exists in the preset distance in the moving direction of the drawer door assembly 2 and the drawer door assembly 2 of the refrigerator stops moving, referring to fig. 2 and 3, the refrigerator of the embodiment of the invention further comprises an alarm unit which is electrically connected with the obstacle sensor 5 or the alarm unit is electrically connected with the controller 6, in this case, when the obstacle sensor 5 detects that the obstacle exists in the preset distance in the moving direction of the drawer door assembly 2, the controller 6 controls the driving device 4 to stop, the alarm unit gives an alarm, and at this time, the user knows that the obstacle exists in the preset distance in the moving direction of the drawer door assembly 2 according to the alarm information, the drawer door assembly 2 is opened after the obstacle needs to be cleared. The mode of warning the user can be displayed by sound or by graphics, for example, the warning unit displays one or two of warning and sound warning for a character code graphic. Only the alarm is displayed through the character code graph, although the alarm is intuitive and convenient for a user to understand, when the user inputs an opening operation instruction to leave the refrigerator, the alarm prompt cannot timely remind the user that an obstacle exists on a drawer path, so that the drawer door assembly is still not opened after the user returns, the time waste is caused, and the user experience is not high; only through audible alarm, although can in time remind the user that there is the barrier on the drawer route, nevertheless it is directly perceived obvious inadequately, therefore, generally speaking, alarm unit adopts the mode of both combinations. In particular, an alarm unit may be integrated in the command input unit 7, for example: the instruction input unit 7 is provided with a display screen 73, information that an obstacle exists in a preset distance in the moving direction of the drawer door assembly 2 can be fed back to the display screen 73, the display screen 73 prompts a user that the obstacle exists in the preset distance in the moving direction of the drawer door assembly 2 in a voice, animation or text mode, and the door is opened automatically after the obstacle needs to be removed.
When the drawer door assembly 2 is stopped at a position between the full open and the full close, after the user removes an obstacle within a preset distance in the movement direction of the drawer door assembly 2, in order to allow the drawer door assembly 2 to continue to finish without completing the movement, a memory unit is provided for recording and storing information of the movement direction. Specifically, the controller 6 of the refrigerator according to the embodiment of the present invention includes a memory unit, where the memory unit is configured to record a moving direction of the drawer door assembly 2, and when the controller 6 controls the driving device 4 to stop during a moving process of the drawer door assembly 2 and starts the driving device 4 again, the controller 6 may record the moving direction of the drawer door assembly 2 according to the memory unit, control the driving device 4 to open and enable the drawer door assembly 2 to continue to move along the moving direction before stopping, so as to correctly complete an opening or closing motion of the drawer door assembly 2 required by an operation instruction input by a user. Wherein the memory unit in the controller 6 determines whether the opening or closing action is being performed before the stop by software recording the manner in which the front drive 4 is operating before the drawer door assembly 2 is stopped partway through. In this case, when the drawer door assembly 2 is stopped at a position between the fully opened position and the fully closed position, the user removes an obstacle within a preset distance in the moving direction of the drawer door assembly 2, the obstacle sensor 5 detects that no obstacle is present within the preset distance in the moving direction of the drawer door assembly 2, and transmits the detection information that no obstacle is present within the preset distance in the moving direction of the drawer door assembly 2 to the controller 6 or is extracted from the obstacle sensor 5 by the controller 6, and at this time, the controller 6 controls the driving device 4 to be activated according to the last moving direction or trajectory of the drawer door assembly 2 recorded in the memory unit, so that the drawer door assembly 2 continues to complete the movement before the stop, thereby completing the opening or closing motion of the drawer door assembly 2 required by the operation instruction input by the user.
Since the obstacle sensor 5 is used to detect whether an obstacle exists within a preset distance in the moving direction of the drawer door assembly 2, the obstacle sensor 5 is disposed on the drawer door panel 2, so that an effective detection area of the obstacle sensor 5 is a range of movement of the drawer door assembly 2. The obstacle sensor 5 may be disposed on the upper portion of the drawer door 21, or may be disposed on the lower portion of the drawer door 21, and generally, the obstacle sensor 5 is disposed on the lower portion of the drawer door 21, so that the overall beauty of the drawer door 21 is not affected. In some embodiments, the obstacle sensor 5 is an infrared sensor, a microwave sensor, or a radar device 51. In view of the better obstacle detection effect of the radar device 51 and the lower cost, the refrigerator according to the embodiment of the present invention employs the radar device 51 as the obstacle sensor 5, specifically, as shown in fig. 3, three radar devices 51 are uniformly distributed at the lower portion of the drawer door panel 21, the three radar devices 51 are all electrically connected to the controller 6 to transmit the detection information to the controller 6 or extract the detection information from the radar devices 51 by the controller 6, each radar device 51 corresponds to an obstacle detection area, the detection area is within the above-mentioned preset distance, when an obstacle exists in the obstacle detection area, the radar device 51 transmits the information that the obstacle exists in the preset distance in the moving direction of the drawer door assembly 2 to the controller 6 or extracts the information from the radar device 51 by the controller 6, the controller 6 controls the driving device 4 to stop, and meanwhile, the alarm unit sends alarm information.
When the obstacle sensor 5 detects that no obstacle exists within a preset distance in the moving direction of the drawer door assembly 2, the controller 6 controls the driving device 4 to start, when the drawer door assembly 2 moves to a fully opened position or a fully closed position, the controller 6 needs to control the driving device 4 to stop, and in order to acquire position information of the drawer door assembly 2, therefore, referring to fig. 4 and 5, the refrigerator of the embodiment of the present invention further includes a push-pull position sensor 9, the push-pull position sensor 9 is electrically connected with the controller 6 and is used for detecting position information of the drawer door assembly 2, wherein the position information at least includes opening position information when the drawer door assembly 2 is fully opened and closing position information when the drawer door assembly is fully closed; when the position information detected by the push-pull position sensor 9 is the open position information or the closed position information, the controller controls the driving device 4 to stop.
