Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

A side-by-side refrigerator is generally provided with a plurality of drawers for storing articles in a sorted manner. The vertical beam is arranged in the side-by-side refrigerator, and the freezing chamber is divided by the vertical beam so as to achieve the aim of storage in a subarea manner. However, since the width of the freezing chamber divided by the vertical beam is reduced, many articles with longer width cannot be directly stored in the refrigerator, and the articles can be placed into the refrigerator after being processed by a user, so that the storage process of the user is very inconvenient. Therefore, in order to meet the storage demand for long-width goods, it is necessary to provide a wide freezing drawer in the side-by-side refrigerator.

A side by side refrigerator is generally configured such that a freezing chamber is divided by providing a turning beam or a center beam, and a freezing drawer is provided in the divided freezing chamber. However, since the door bodies of the side-by-side combination refrigerator are arranged as side-by-side combination doors, if one or more oversized drawers are required to be arranged in the refrigerator, the middle beam cannot be directly arranged in the refrigerator body of the refrigerator. The arrangement of the turnover beam is complex, and the condensation phenomenon is easily generated by arranging the turnover beam.

The condensation phenomenon not only affects the appearance of the refrigerator, but also adsorbs dust and impurities in the air. Long-time condensation can cause corrosion and rusting of metal parts, smelling and mildewing of plastic parts and reduction of the service life of the refrigerator.

In order to solve the above problems, referring to fig. 1, the present application provides a drawer for a refrigerator, which is applied to a refrigerator including a cabinet 100 and an independent compartment 200, wherein:

the independent compartment 200 is disposed in the cabinet 100, and the door 300 is disposed in the independent compartment 200. The number of the door bodies 300 is greater than or equal to two, wherein at least two door bodies 300 are arranged in a split manner, and a door body gap is arranged between the two door bodies 300.

The refrigerator drawer includes a drawer body 500, a temperature sensor 600, a contact sensing assembly 700 and a heating assembly 800, wherein:

referring to fig. 2, the drawer body 500 is disposed in the independent compartment 200, and the drawer body 500 is engaged with the independent compartment 200, so that the drawer body 500 is opened or closed from the independent compartment 200. Wherein, the drawer body 500 can be clamped with the independent compartment 200 by adopting a rail, for example: the track can adopt a bottom-supporting drawer slide rail which is hidden at the bottom of the drawer and is firm and durable; the steel ball type drawer slide rail is matched with a precise steel ball and slides stably; the roller type drawer slide rail has a simple structure and consists of a pulley and two rails; wear-resisting nylon slide rail, wear-resisting and resilience are soft.

The heating assembly 800 is disposed on the drawer body 500 corresponding to the gap of the door body. After the refrigerator starts cooling, the temperature in the independent compartment 200 is gradually decreased, resulting in a large temperature difference between the temperature of the air in the independent compartment 200 and the temperature of the air outside the cabinet 100. Although the door 300 is provided in the refrigerator to seal the cold air in the independent compartment 200, the cold air may leak out from the door gap; and when the user opens and closes the door 300 during use, the cool air may be leaked from the independent compartment 200. The leaked cold air is attached to the outer wall of the drawer body 500 corresponding to the gap of the door body, so that the temperature of the drawer body 500 corresponding to the gap of the door body is low. When the air outside the cabinet 100 meets the low-temperature drawer body 500, the air reaches the dew point temperature and liquefies into liquid on the surface thereof, and condenses into dew. Therefore, the heating assembly 800 is disposed on the drawer body 500 corresponding to the gap of the door body. The heating assembly 800 may employ one or more turns of heating wire. When the heating wires are electrified, the heating wires start to heat, the surface temperature of the drawer body 500 at the gap of the door body starts to rise, and therefore condensation can be evaporated; and after the surface temperature of the drawer body 500 at the gap of the door body is increased, the surface temperature is higher than the dew point temperature, and the possibility that air outside the box body 100 is condensed on the surface of the drawer body 500 is reduced.

The contact sensing assembly 700 is disposed on the drawer body 500 and the box body 100, and the contact sensing assembly 700 is used for detecting an open/close state of the drawer body 500. The sensing assembly 700 on the drawer body 500 and the box body 100 can detect the position change between the drawer body 500 and the box body 100, and the opening and closing state of the drawer body 500 can be judged according to the position change, so that the heating assembly 800 is opened when the drawer body 500 is in the closed state; when the drawer body 500 is in the open state, the heating assembly 800 is turned off. When the user opens the drawer body 500 from the independent compartment 200, the heating assembly 800 is powered off, so that the phenomenon of electric leakage of the heating assembly 800 can be avoided, and the safety of the drawer of the refrigerator is improved.

In some embodiments, the contact sensing assembly 700 includes a hall sensor 701 and a magnet 702. The hall sensor 701 is arranged on the drawer body 500, the magnetic member 702 is arranged on the box body 100, and the hall sensor 701 and the magnetic member 702 are fixed at the contact position of the drawer body 500 and the box body 100. The hall sensor 701, also known as a hall effect sensor, is a transducer that converts a changing magnetic field into a change in output voltage. Hall sensors are suitable for measuring magnetic fields and, in addition, can measure physical quantities which generate and influence magnetic fields, as are used, for example, in proximity switches, hall sensors, position measurement, rotational speed measurement and current measurement devices. The magnetic member 702 may be made of a permanent magnet material, such as: magnets, permanent magnets, etc.

When the drawer body 500 is opened from the independent compartment 200, the distance between the magnetic member 702 and the hall sensor 701 is changed, and the magnetic field of the magnetic member 702 measured by the hall sensor 701 is also changed. Therefore, the open/close state of the drawer body 500 can be judged by the change of the magnetic field measured by the hall sensor 701.

The temperature sensor 600 is disposed on the heating element 800, and the temperature sensor 600 is a sensor capable of sensing temperature and converting the sensed temperature into a usable output signal. The temperature sensor 600 is used to detect the temperature of the heating assembly 800, so that the refrigerator generates a failure alarm prompt when the state that the temperature detected by the temperature sensor 600 is not within the preset temperature range continues for a preset time. For example: the temperature of the heating assembly 800 during normal operation is 4-6 degrees celsius, and the preset time is 10 seconds. If the temperature detected by the temperature sensor 600 lasts for 10 seconds and is 2 ℃, it is determined that the heating assembly 800 is abnormal, and an alarm prompt is generated.

In some embodiments, referring to FIG. 5, the heating assembly 800 includes a first heating element 801 and a second heating element 802, the first heating element 801 being connected in parallel with the second heating element 802. After the first heating member 801 is turned on in the refrigerator, if a state in which the temperature detected by the temperature sensor 600 is not within the preset temperature range continues for a preset time, the first heating member 801 malfunctions, at which time the first heating member 801 is turned off and the second heating member 802 is turned on. Second heating element 802 acts as a backup heating element in heating assembly 800 to ensure that the refrigerator drawer will still function properly in the event of a failure of first heating element 801.

In some embodiments of the present application, the refrigerator drawer further comprises a wireless power supply assembly 900. The wireless power supply module 900 employs a wireless power supply technology, which is a technology of transferring power energy from a power generation device or a power supply terminal to a power receiving device without via an electrical conductor. Wireless energy transfer is a generic term that can be achieved using a variety of different technologies, including electric, magnetic, and electromagnetic waves. The transmitter converts the electrical energy into an energy state corresponding to the field, which is transmitted through a space and received by one or more receivers and converted back into electrical energy. The wireless power supply assembly 900 in the present application includes a wireless transmitting device 901 and a wireless receiving device 902, and the wireless transmitting device 901 wirelessly transmits power to the wireless receiving device 902. The wireless transmitter 901 is disposed on the box 100, and the wireless receiver 902 is disposed on the drawer body 500. The wireless receiving device 902 is electrically connected to the heating element 800 such that the wireless receiving device 902 provides power to the heating element 800. The line end exposure can be avoided by the wireless power supply assembly 900. The wire terminals of the wireless power supply assembly 900 are embedded in the box body 100, so that the condition that wires are disorderly routed in the refrigerator can be avoided, and the problem of electric leakage caused by a large amount of water vapor in the refrigerator is also avoided.

Based on the above refrigerator drawer, referring to fig. 4, some embodiments of the present application further provide a refrigerator, including a box body 100, an independent compartment 200, a main control board 400, and the refrigerator drawer described in the above embodiments, wherein:

the independent compartment 200 is disposed in the cabinet 100, and the independent compartment 200 is provided with a door 300. The number of the door bodies 300 is greater than or equal to two, referring to fig. 3, every two door bodies 300 are arranged in a split manner, a door body gap is arranged between the two door bodies 300, and the main control panel 400 is arranged on the box body 100. The contact sensing assembly 700 of the refrigerator drawer is electrically connected to the main control board 400 to transmit a switching signal of the drawer body 500 to the main control board 400. The temperature sensor 600 and the heating assembly 800 of the refrigerator drawer are electrically connected with the main control board 400. The main control board 400 is a control element of the whole refrigerator core, and a control circuit is provided inside the main control board 400, by which various elements in the box body 100 can be controlled. The main control board 400 is configured to:

receiving a switch signal detected by the contact sensing assembly 700, and acquiring an on-off state of the drawer body according to the switch signal, and if the drawer body 500 is in an off state, turning on the heating assembly 800; if the drawer body 500 is in the open state, the heating assembly 800 is turned off;

receiving a temperature signal of the temperature sensor 600, and acquiring the temperature of the heating assembly 800 according to the temperature signal; and generating a fault alarm prompt when the state that the temperature is not within the preset temperature range continuously reaches the preset time.

The main control board 400 may control the heating assembly 800 to be turned on or off. The refrigerator can be prevented from generating dew by turning on the heating assembly 800. When the drawer body 500 is opened, the main control panel 400 closes the heating assembly 800, so that the heating assembly 800 can be prevented from generating electric leakage, and the safety of the refrigerator is improved. The main control board 400 also detects the temperature of the heating assembly 800 through the temperature sensor 600, and can alarm and remind a user in time when the heating assembly 800 breaks down.

In some embodiments, after receiving the temperature signal of the temperature sensor 600, the main control board 400 is further configured to: turning off the heating assembly 800 if the temperature is greater than or equal to a first preset temperature threshold; if the temperature is less than a second preset temperature threshold, the heating assembly 800 is turned on, and the second preset temperature threshold is less than the first preset temperature threshold. For example: in practical applications, if the temperature of the heating element 800 is 4-6 ℃, the first temperature threshold is set to 6 ℃ and the second temperature threshold is set to 4 ℃. After the heating assembly 800 is powered on, the temperature detected by the temperature sensor 600 reaches 6 degrees centigrade, at this time, the main control board 400 can control to turn off the heating assembly 800, the power consumption of the refrigerator can be saved, and the temperature of the heating assembly 800 can be maintained between 4 and 6 degrees centigrade within a period of time. When the temperature detected by the temperature sensor 600 is less than 4 degrees celsius, the main control board 400 turns on the heating element 800 again to maintain the temperature of the heating element 800 within the range of 4-6 degrees celsius.

In some embodiments, the master control board 400 is configured to: detecting the opening time of the drawer body 500 if the drawer body 500 is in an open state; and if the starting time is greater than the preset time threshold, generating a fault alarm prompt. When the user uses the refrigerator, the user may forget to close the drawer body 500, and the cooling capacity in the refrigerator may leak out. Therefore, a certain time threshold is set, and when it is detected that the drawer body 500 is in the open state for a certain time, an alarm prompt can be generated to remind the user to close the drawer body 500. For example: the time threshold is set to 10 minutes, and the user forgets to close the drawer body 500 after opening the drawer body 500 to take an item. After 10 minutes, the main control board 400 will automatically generate an alarm prompt message to remind the user to close the drawer body 500.
