Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of refrigeration equipment, and particularly relates to a rotating basket of a round barrel cabinet and a control method. BACKGROUND

[0002] A refrigerator is a device for storing food and other items at low temperature. There are two types of household and commercial refrigerators, and commercial refrigerators are used in restaurants, bars, food processing and supermarkets. Among them, the round barrel cabinet is a kind of commercial refrigerator, which has a unique shape of a round barrel and can attract customers.

[0003] At present, the round barrel cabinet mostly includes an outer barrel, an inner barrel and a door body, the basket is arranged in the inner barrel, and the goods are placed in the basket, and the door body is hinged to the opening of the inner barrel through the cross beam. In the prior art, the basket is placed in the inner barrel, and the temperature at the center of the inner barrel is different from that at the edge, and the refrigeration effect on the goods is uneven. At the same time, because the cross beam blocks the view, the user cannot see all the goods, which affects the display effect of the goods. SUMMARY

[0004] In view of the deficiencies in the related art, the present application provides a rotating basket of a round barrel cabinet and a control method, which drives the storage basket to rotate through a rotating drive member, so that the cold air in the inner barrel flows and is uniformly distributed, thereby ensuring the refrigeration effect of the goods in the storage basket. The second sensor detects whether there is a person in front of the round barrel cabinet, and when there is a person in front of the round barrel cabinet, the speed of the storage basket is reduced, which facilitates the user to observe the goods, thereby solving the technical problems of uneven refrigeration effect and poor display effect of goods in the prior art.

[0005] The present application provides a rotating basket of a round barrel cabinet, which comprises an outer barrel, an inner barrel, a cross beam and a door body; the inner barrel is arranged inside the outer barrel, the cross beam is arranged at the opening of the top of the inner barrel and the outer barrel, and the door body is hinged to the cross beam;

[0006] The rotating basket of the round barrel cabinet comprises:

[0007] a storage basket, which is arranged in the inner barrel;

[0008] a rotating drive member, which is arranged in the outer barrel and used to drive the storage basket to rotate;

[0009] a first sensor, which is used to detect whether the door body is opened;

[0010] a second sensor, which is arranged in the outer barrel and used to detect whether there is a person or object beside the outer barrel;

[0011] an electric control panel, which is electrically connected with the first sensor, the second sensor and the rotating drive member.

[0012] In the technical scheme, the rotating driving member drives the basket to rotate, so that cold air in the inner barrel flows and is uniformly distributed, and the refrigeration effect of the goods in the basket is ensured. The second sensor detects whether there is a person in front of the cylindrical cabinet. When there is a person in front of the cylindrical cabinet, the rotating speed of the basket is reduced, so as to facilitate the user to observe the goods.

[0013] In some embodiments, the first sensor includes a door magnet and a Hall switch, the door magnet is arranged on the door body, and the Hall switch is arranged at an opening of the outer barrel or the inner barrel. The Hall switch generates an electrical signal through the magnetic force change of the door magnet.

[0014] In the technical scheme, when the door body is opened, the Hall switch loses the attraction of the door magnet, so that the Hall sensor sends an electrical signal to the control panel.

[0015] In some embodiments, the top of the outer barrel is provided with a ring seat, and the ring seat is also connected with the top of the inner barrel; and the cross beam is arranged on the ring seat.

[0016] In the technical scheme, the ring seat closes the gap between the top of the inner barrel and the outer barrel, and facilitates the installation of the cross beam and the door body.

[0017] In some embodiments, the door body is provided with a plurality of door bodies, each of the door bodies is hinged to the cross beam, and the number of the first sensors is the same as and one-to-one corresponds to the number of the door bodies.

[0018] In the technical scheme, the plurality of door bodies allows the user to open different door bodies in multiple directions to take things in the basket, and facilitates the user to use.

[0019] In some embodiments, the rotating driving member is arranged at the bottom of the inner barrel, an output shaft of the rotating driving member is connected with a tray, and the basket is arranged on the tray.

[0020] In the technical scheme, the tray is used to connect the rotating driving member and the basket. The stability of the rotation of the basket is improved.

[0021] The application also provides a control method of a rotating basket of a cylindrical cabinet, which is applied to the rotating basket of the cylindrical cabinet as described above, and the rotating driving member has a first rotating speed and a second rotating speed which are sequentially reduced in rotating speed.

[0022] When the first sensor detects that the door body is closed and the second sensor does not detect a person or an object, the rotating driving member is controlled to operate at the first rotating speed.

[0023] When the first sensor detects that the door is closed and the second sensor detects a person or object, the rotating drive is controlled to operate at a second rotating speed.

[0024] In the technical solution, the second sensor detects whether there is a person in front of the cylindrical cabinet, and when there is a person in front of the cylindrical cabinet, the rotating speed of the storage basket is reduced to facilitate the user to observe the goods, thereby solving the technical problems of uneven refrigeration effect and poor goods display effect in the prior art.

[0025] In some embodiments, the rotating drive also has a third rotating speed lower than the second rotating speed; when the first sensor detects that the door is opened, the rotating drive is controlled to operate at the third rotating speed.

[0026] In the technical solution, when the user opens the door, it means that the goods in the storage basket need to be taken out, and at this time, the rotating speed of the storage basket is reduced to the lowest, facilitating the user to take.

[0027] In some embodiments, when the first sensor detects that the door is opened and the second sensor detects a person or object, the rotating drive is controlled to operate at the third rotating speed.

[0028] In the technical solution, when the second sensor detects a person or object and the first sensor detects that the door is opened, the rotating basket operates at the third rotating speed. When the first sensor is false, the storage basket cannot rotate at a normal rotating speed.

[0029] Based on the above technical solution, in the embodiment of the present application, the rotating drive drives the storage basket to rotate, so that the cold air in the inner barrel flows, and the cold air is uniformly distributed, ensuring the refrigeration effect of the goods in the storage basket. The second sensor detects whether there is a person in front of the cylindrical cabinet, and when there is a person in front of the cylindrical cabinet, the rotating speed of the storage basket is reduced to facilitate the user to observe the goods. When the user opens the door, it means that the goods in the storage basket need to be taken out, and at this time, the rotating speed of the storage basket is reduced to the lowest, facilitating the user to take, thereby solving the technical problems of uneven refrigeration effect and poor goods display effect in the prior art.

[0044] As shown in the accompanying drawings Figure 1 to the accompanying drawings Figure 5 As shown in the accompanying drawings

[0045] The rotating basket of the barrel cabinet comprises a storage basket 800, a rotating driving member 110, a first sensor 600, a second sensor 700 and an electric control board, wherein the storage basket 800 is arranged in the inner barrel 200; the rotating driving member 110 is arranged in the outer barrel 100 and is used to drive the storage basket 800 to rotate; the first sensor 600 is used to detect whether the door body 500 is opened; the second sensor 700 is arranged in the outer barrel 100, and is used to detect whether there is a person or object beside the outer barrel 100; and the electric control board is electrically connected with the first sensor 600, the second sensor 700 and the rotating driving member 110.

[0046] The storage basket 800 is driven to rotate by the rotating driving member 110, so that the cold air in the inner barrel 200 flows and is uniformly distributed, thereby ensuring the refrigeration effect of the goods in the storage basket 800. The second sensor 700 is used to detect whether there is a person in front of the barrel cabinet, and when there is a person in front of the barrel cabinet, the rotating speed of the storage basket 800 is reduced, thereby facilitating the user to observe the goods.

[0047] In some embodiments, the top of the outer barrel 100 is provided with a ring seat 400, the ring seat 400 is also connected with the top of the inner barrel 200, and the crossbeam is arranged on the ring seat 400.

The Hall switch 702 generates an electrical signal by the magnetic force change of the door magnet 701. When the door body 500 is opened, the Hall switch 702 loses the suction force of the door magnet 701, and thus the Hall sensor sends an electrical signal to the control panel.

[0049] Further, the Hall switch 702 is mounted on the ring seat 400. When the door body 500 is closed, the door body 500 is located in the ring seat 400, and the door magnet 701 on the door body 500 is close to the Hall sensor.

[0050] In another embodiment, the first sensor 600 is an infrared sensor, and the first sensor 600 is inlaid in the ring seat 400. When the door body 500 is closed, the infrared sensor of the first sensor 600 senses the door body 500. When the door body 500 is opened, the infrared light of the first sensor 600 cannot sense the door body 500, and at this time, the first sensor 600 sends an electrical signal to the control panel.

The ring seat 400 is coaxially arranged on the top of the outer tub 100, and the top of the inner tub 200 and the top of the outer tub 100 are connected with the ring seat 400. Therefore, the ring seat 400 closes the gap between the inner tub 200 and the outer tub 100.

[0052] In some embodiments, the second sensor 700 is arranged on the outer peripheral wall of the ring seat 400. The second sensor 700 is an infrared sensor, and when the infrared ray of the second sensor 700 senses a person or an object, the second sensor 700 sends an electrical signal to the control panel.

[0053] Further, the second sensor 700 is arranged at intervals around the axis of the ring seat 400, and a plurality of second sensors 700 are arranged at intervals around the axis of the ring seat 400. The plurality of second sensors 700 detect whether a user is close to the cylindrical cabinet, so as to avoid a blind area and improve the detection accuracy.

[0054] In another embodiment, the second sensor 700 is arranged on the outer peripheral wall of the outer tub 100, and a plurality of second sensors 700 are arranged at intervals around the axis of the outer tub 100.

[0055] In some embodiments, the cylindrical cabinet further comprises a base 300, the base 300 is disc-shaped, and an axis of the base 300 is vertically arranged. A bottom of the outer barrel 100 is connected to an upper surface of the base 300. An outer diameter of the base 300 is the same as an outer diameter or an inner diameter of the bottom end of the outer barrel 100. The inner barrel 200 is cylindrical, and the inner barrel 200 is located inside the outer barrel 100, and axes of the inner barrel 200, the base 300 and the outer barrel 100 are collinear.

[0056] In another embodiment, the second sensor 700 is arranged on the outer peripheral wall of the base 300. The second sensor 700 is arranged at multiple positions around the axis of the base 300.

[0057] Please refer to Figures 1 to 5 In some embodiments, the door body 500 is provided in plurality, each door body 500 is hingedly connected to the cross beam, and the number of the first sensors 600 is the same as and one-to-one corresponds to the number of the door bodies 500. Through the plurality of door bodies 500, the user can open different door bodies 500 in multiple directions to take out the things in the storage basket 800, which is convenient for the user to use.

[0058] In some embodiments, the cross beam is horizontally arranged, and the axis of the outer barrel 100 penetrates the cross beam. Two ends of the cross beam are connected to the inner peripheral wall of the ring seat 400.

[0059] Further, the door body 500 is two, and the door bodies 500 are respectively located on the left and right sides of the cross beam, and the door bodies 500 respectively open or close the left and right sides of the cross beam.

[0060] In some embodiments, the number of the second sensors 700 is the same as the number of the door bodies 500, and the second sensors 700 respectively correspond to the door bodies 500.

[0061] Please refer to Figures 1 to 5 In some embodiments, the rotary driving member 110 is arranged at the bottom of the inner barrel 200, an output shaft of the rotary driving member 110 is connected to the tray 900, and the storage basket 800 is arranged on the tray 900. The connection between the rotary driving member 110 and the storage basket 800 is completed through the tray 900. The stability of the rotation of the storage basket 800 is improved.

[0062] In another embodiment, the rotary driving member 110 is arranged at the base 300, and an output shaft of the rotary driving member 110 penetrates the bottom wall of the inner barrel 200 and is connected to the tray 900.

[0063] In some embodiments, the tray 900 and the storage basket 800 are connected through buckling.

[0064] In another embodiment, an output shaft of the rotary driving member 110 is directly connected to the storage basket 800.

[0065] Further, the inner circumferential wall or the bottom wall of the inner barrel 200 is provided with a rolling member or a supporting block, and the tray 900 is supported by the rolling member or the supporting block, so that the storage basket 800 is prevented from tilting. The rolling member includes, but is not limited to, a roller or a ball.

[0066] In some embodiments, the rotating driving member 110 includes, but is not limited to, a motor or a motor.

[0067] Please refer to Figure 6 and Figure 7 The application further provides a control method of a rotating basket of a barrel cabinet, which is applied to the rotating basket of the barrel cabinet as described above, and the rotating driving member 110 has a first rotating speed and a second rotating speed which are sequentially reduced.

[0068] When the first sensor 600 detects that the door body 500 is closed and the second sensor 700 does not detect a person or an object, the rotating driving member 110 is controlled to operate at the first rotating speed.

[0069] When the first sensor 600 detects that the door body 500 is closed and the second sensor 700 detects a person or an object, the rotating driving member 110 is controlled to operate at the second rotating speed. The second sensor 700 detects whether there is a person in front of the barrel cabinet, and when there is a person in front of the barrel cabinet, the rotating speed of the storage basket 800 is reduced, so that the user can conveniently observe the goods, thereby solving the technical problems of uneven refrigeration effect and poor goods display effect in the prior art.

[0070] In some embodiments, the rotating driving member 110 further has a third rotating speed which is lower than the second rotating speed; and when the first sensor 600 detects that the door body 500 is opened, the rotating driving member 110 is controlled to operate at the third rotating speed. When the user opens the door body 500, it means that the goods in the storage basket 800 need to be taken out, and at this time, the rotating speed of the storage basket 800 is reduced to the lowest, so that the user can conveniently take the goods.

[0071] In some embodiments, when the first sensor 600 detects that the door body 500 is opened and the second sensor 700 detects a person or an object, the rotating driving member 110 is controlled to operate at the third rotating speed. When the second sensor 700 detects a person or an object and the first sensor 600 detects that the door body 500 is opened, the rotating basket operates at the third rotating speed. When the first sensor 600 erroneously reports, the storage basket 800 cannot rotate at a normal rotating speed.

[0072] In some embodiments, when the first sensor 600 detects that the door body 500 is opened, and the second sensor 700 detects that a person or an object passes after a preset time, the rotating drive 110 stops running, so that the rotating basket stops rotating. When the first sensor 600 detects that the door body 500 is opened for a long time, and the second sensor 700 confirms that a person is detected beside the cylindrical cabinet, it can be judged that the current cylindrical cabinet may be in a state of replenishment or cleaning, and therefore the rotation of the rotating drive 110 is stopped.

[0073] In some embodiments, a biological sensor is further arranged on the cylindrical cabinet, and the biological sensor can be installed on the ring seat 400, the outer barrel 100 or the base 300. The biological sensor is used to detect whether it is a living being or an object. When the first sensor 600 detects that the door body 500 is closed, and the second sensor 700 detects a person or an object, and the third sensor detects that it is a living being, the rotating drive 110 is controlled to run at a second rotating speed.

[0074] When the first sensor 600 detects that the door body 500 is opened, and the second sensor 700 detects a person or an object, and the third sensor detects that it is a living being, the rotating drive 110 is controlled to run at a third rotating speed.

[0075] In some embodiments, a motion sensor is further arranged on the cylindrical cabinet, and the motion sensor is used to detect whether there is an object moving around the cylindrical cabinet. The motion sensor can be installed on the ring seat 400, the outer barrel 100 or the base 300, and the detection range of the motion sensor is greater than that of the second sensor 700. When the motion sensor detects that there is movement around, the second sensor 700 starts to detect. The motion sensor can be arranged at the same time as the biological sensor.

[0076] In some embodiments, a camera is arranged above the cylindrical cabinet, and the camera is used to detect whether a person is close to the cylindrical cabinet. The camera is electrically connected with the electric control board, and the camera has a portrait recognition function. When the camera detects that a user is close to the cylindrical cabinet, and the first sensor 600 detects that the door body 500 is closed, the rotating drive 110 is controlled to run at a second rotating speed. When the camera detects that a user is close to the cylindrical cabinet, and the first sensor 600 detects that the door body 500 is opened, the rotating drive 110 is controlled to run at a third rotating speed.

[0077] In some embodiments, the control method of the rotating basket of the cylindrical cabinet is preset in the electric control board.

[0078] Through the description of the rotating basket of the cylindrical cabinet and the control method of the cylindrical cabinet in the embodiments of the present application, it can be seen that the rotating basket of the cylindrical cabinet and the control method of the cylindrical cabinet in the embodiments of the present application have at least one or more of the following advantages:

[0079] 1. The rotating driving member 110 drives the basket 800 to rotate, so that the cold air in the inner barrel 200 flows and is uniformly distributed, ensuring the refrigeration effect of the goods in the basket 800.

[0080] 2. The second sensor 700 detects whether there is a person in front of the cylindrical cabinet. When there is a person in front of the cylindrical cabinet, the rotating speed of the basket 800 is reduced to facilitate the user to observe the goods. When the user opens the door body 500, it means that the goods in the basket 800 need to be taken out. At this time, the rotating speed of the basket 800 is reduced to the lowest, facilitating the user to take.

[0081] Finally, it should be noted that: the various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to.

[0082] The above embodiments are only used to illustrate the technical solutions of the present application but not to limit it; although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones; without departing from the spirit of the technical scheme of the present application, they should be covered in the technical scheme range of the present application.
