Where Radar 132 is transliteration of the english Radar, an abbreviation from radio detection and ranging, meaning "radio detection and ranging". That is, radar 132 may find objects and determine their spatial locations by radio methods. Therefore, the radar 132 is also referred to as "radio positioning", and the radar 132 is an electronic device that detects a target using electromagnetic waves. The radar 132 emits electromagnetic waves to irradiate the target and receives echoes thereof, thereby obtaining information of the distance, the distance change rate (radial velocity), the azimuth, the altitude, and the like of the target to the electromagnetic wave emission point. The refrigerator 100 in the present embodiment is provided with a radar 132 mainly for sensing a user distance in front of the refrigerator 100.

In a specific embodiment, the number and structure of the storage spaces defined in the case 110 may be configured according to the needs, and the storage spaces may be configured as a refrigerating space, a freezing space, a temperature-changing space, or a fresh-keeping space according to the purposes. Each storage space may be divided into a plurality of storage areas by a partition plate, and articles are stored using racks or drawers. As shown in fig. 1, the refrigerator 100 of the present embodiment may be provided with three storage spaces from top to bottom, and the storage space above may be provided as a refrigerating space, and the two storage spaces below may be provided as freezing spaces.

The door 120 may be disposed corresponding to the storage spaces, i.e., each storage space corresponds to one or more doors 120. The number of storage spaces and the door 120, and the functions of the storage spaces may be actually selected according to the specific situation. The door 120 may be pivotally disposed on the front surface of the case 110, and may be opened in a drawer manner, so as to implement a drawer-type storage space, where the drawer-type storage space is often provided with a metal sliding rail, so that the effect of opening and closing the drawer is soft and noise is reduced. As shown in fig. 1, a door body that is pivoted to open may be provided in a storage space above the refrigerator 100 of the present embodiment, and drawer-type opening may be implemented in two storage spaces below.

In addition, the refrigerator 100 may further include: and a refrigeration system configured to provide cooling to the storage space. Also, the refrigeration system may be a compression refrigeration system including an evaporator, a condenser, a compressor, and the like. The compressor and the second condenser may be disposed in a compressor compartment and the evaporator may be disposed in a cooling chamber. The refrigeration system provides different amounts of cold to the refrigerated space and the refrigerated space such that the temperatures within the refrigerated space and the refrigerated space are also different. Wherein the temperature in the refrigerated space is generally between 2 ℃ and 10 ℃, preferably between 3 ℃ and 8 ℃. The temperature in the refrigerated space is generally in the range of-22 ℃ to-14 ℃. The optimal storage temperatures of different kinds of foods are not the same, and thus the storage spaces suitable for storage are not the same. For example, fruit and vegetable foods are suitable for storage in a refrigerated space, while meat foods are suitable for storage in a frozen space.

As shown in fig. 1, the refrigerator 100 of the present embodiment may be a side-by-side refrigerator, and the door may include a first door 121 and a second door 122 that are relatively opened. In a specific embodiment, the storage space above may be a side-by-side door. That is, the upper storage space may be provided with the first door 121 and the second door 122 opened relatively, respectively. More specifically, the first door 121 and the second door 122 are each connected to the case 110 through a pivot shaft (not shown), thereby achieving pivotal opening. The first door body 121 serves as a left door body with its pivot axis at the top left side thereof, and the second door body 122 serves as a right door body with its pivot axis at the top right side thereof.

In a preferred embodiment, the display bracket 131 may be disposed at a side of the first door 121 or the second door 122 remote from the pivot shaft. As shown in fig. 1, the display bracket 131 is disposed at a side of the second door 122 away from the pivot axis. The display bracket 131 is far away from one side of the pivot shaft, namely, is close to one side of the contact surface when the first door body 121 and the second door body 122 are closed, and is also closer to the transverse center of the refrigerator 100, so that the sensing range and the sensing angle of the radar 132 on the display bracket 131 can be ensured to be better, and the sensing effect of the radar 132 is effectively improved.

In a preferred embodiment, the display bracket 131 is a non-metallic material. For example, the display bracket 131 may be made of plastic. In a specific embodiment, the material of the display bracket 131 may be Polystyrene (PS for short), which is a polymer synthesized by radical addition polymerization of styrene monomer, and which is a colorless transparent thermoplastic having a glass transition temperature of more than 100 ℃. In addition, the general PS plastic is an amorphous random polymer, and has excellent heat insulation, insulation and transparency.

In another specific embodiment, the material of the display bracket 131 may also be acrylonitrile butadiene styrene (Acrylonitrile Butadiene Styrene). The ABS plastic is a terpolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S), and the relative content of the three monomers can be arbitrarily changed to prepare various resins. ABS plastic has the common properties of three components, A makes it resistant to chemical corrosion and heat, and has certain surface hardness, B makes it have high elasticity and toughness, S makes it have the processing and forming characteristics of thermoplastic plastic and improves electric performance. Therefore, the ABS plastic is a tough, hard and rigid material with easily obtained raw materials, good comprehensive performance, low price and wide application range. Both PS plastic and ABS plastic are well suited to make the display bracket 131 to be placed on the refrigerator 100, giving attention to both life and production costs.

As shown in fig. 3 and 4, in a preferred embodiment, the radar 132 may be stuck to the rear side of the display bracket 131. The original components of the refrigerator 100 provided with the display bracket 131 are utilized, the radar 132 is fixed without additional fixing components, the radar 132 is arranged on the rear side of the display bracket 131, an additional structure is not required to be arranged for modifying the appearance, and the structure is simplified and meanwhile the production cost is effectively reduced. As shown in fig. 4, a catch 133 may be provided at the lower rear side of the display bracket 131 for catching the radar 132 behind the display bracket 131.

More importantly, since the display bracket 131 is made of a nonmetallic material, the radar 132 has the characteristic of penetrating nonmetallic materials and can not leak. Therefore, the radar 132 is disposed at the rear side of the display bracket 131, so that the sensing angle and the distance are optimally ensured, the sensing effect of the radar 132 can be ensured to the greatest extent, and the sensing effect is not reduced due to the display bracket 131 in front of the radar 132.

In a specific embodiment, the refrigerator 100 may further include: a hinge case (not shown) is fixed to the case 110 and configured to receive the main control cable. As shown in fig. 4, the refrigerator 100 may further include: a branch cable 134, one end of which is connected to the radar 132, and the other end of which is connected to the main control cable. And, branch cable 134 also can be fixed through some structures at display bracket 131 rear side, avoids dropping the winding, further promotes whole operational reliability.

In a preferred embodiment, radar 132 is at a predetermined height from the ambient floor of refrigerator 100. Since the human body of the user has a certain height, the position of the radar 132 is set to a preset height from the ground, so that the sensing effect of the radar 132 can be further ensured. More preferably, the predetermined height is 1.4 meters to 1.6 meters. For example, considering that the human body height is about 1.5 meters or so, the preset height between the radar 132 and the ground may be 1.5 meters. The requirement on the standing position of the user is reduced, the height can meet the requirement of 1.5 meters, and the human engineering is met. The radar 132 is provided on the door, and is located at the forefront of the refrigerator 100, thereby maximizing the sensing distance.

The refrigerator 100 may further include: a display panel (not shown) disposed at a rear side of the display bracket 131, configured to display operation parameters of the refrigerator 100. In fact, the display bracket 131 originally has the function of fixing the display panel, and the refrigerator 100 in the embodiment does not additionally increase the setting part for fixing and modifying the radar 132, but utilizes the original display bracket 131, does not change the appearance, ensures the universality and reduces the production cost.

In a preferred embodiment, the display bracket 131 is provided with a sensing film patch attached to the front thereof, configured to sense a touch pressure signal. And, the door body may include a panel 123 disposed at a front side of the display bracket 131. That is, one surface of the sensing film may be attached to the front side of the display bracket 131, and the other surface may be attached to the inner surface of the panel 123 of the door body. As shown in fig. 1 to 3, since the display bracket 131 is disposed on the second door 122, the other surface of the sensing film may be bonded to the inner surface of the panel 123 of the second door 122.

In one embodiment, the panel 123 may be a glass material. It should be noted that, the display bracket 131 is made of a non-metal material, the panel 123 of the door body is made of a glass material, and also made of a non-metal material, and the radar 132 can penetrate through the non-metal material, i.e. all shielding objects in front of the radar 132 do not affect the sensing effect. Further, since the panel 123 is made of glass and has a transparent property, the display bracket 131 and the display panel at the rear can be exposed without being blocked. The area other than the panel 123 corresponding to the display bracket 131 may be printed with a coating or other printed structures to avoid leaking out of the display bracket 131 and other structures outside the display panel inside the door body.

As shown in fig. 3 and 4, the display bracket 131 may have a hollowed portion, and the hollowed portion may expose a display panel behind the display bracket 131 to display operation parameters of the refrigerator 100. It should be noted that, the thickness of the display bracket 131 may be relatively thin, so as to ensure that the sensing film is attached to the front side of the display bracket 131 relatively smoothly, without being rugged, and also avoid the damage of the sensing film caused by deeper hollowed-out portions when the user presses the panel 123. In a specific embodiment, when the user presses the panel 123 corresponding to the hollowed-out portion of the display bracket 131, the adjustment of the operation parameters is implemented, that is, the display panel implements the functions of touch control and display. In another specific embodiment, the user can adjust the operation parameters when pressing the panel 123 corresponding to the non-hollowed-out portion of the display bracket 131.

In a preferred embodiment, the operating parameters displayed by the display panel may include: the type of storage space of the refrigerator 100, the set temperature of each storage space, the operation mode, and the like. For example, the display panel may display specific set temperatures of a refrigerating space and a freezing space of the refrigerator 100, and an operation mode of the storage space is purification, intelligence, or holiday. In addition, the display panel may also be displayed with a locking pattern, and by pressing the panel 123 at the locking pattern, the state switching of the display panel between sleep and awake may be achieved.

As shown in fig. 4, the radar 132 may be disposed below the rear side of the display bracket 131, and in practice, the display panel may be disposed above the rear side of the display bracket 131. Radar 132 is disposed below the display panel. However, in other embodiments, the up-down positions of the radar 132 and the display panel may be configured in other ways, and only a direct combination of the configuration and the display is required to ensure that the radar 132 is at a predetermined height from the ground.

The refrigerator 100 further includes: and a rear cover 135 covering the radar 132 and the rear side of the display panel to separate an external insulation layer. Fig. 2 shows a case where the rear cover 135 is actually provided, and fig. 3 shows a case where the rear cover 135 is not provided to show the radar 132 inside. In a specific embodiment, the case 110 may include a housing, a liner, and an insulation layer, where the insulation layer is disposed between the housing and the liner, for isolating external heat and avoiding cold loss of the storage space. In fact, the heat insulation layer is filled in the door body, and the functions of isolating external heat and avoiding cold loss of the storage space are achieved. By providing the rear cover 135 behind the display bracket 131, the radar 132 and the display panel can be completely separated from the external heat insulating layer, and the heat insulating layer is prevented from affecting the normal operation of the display panel and the radar 132. In addition, under the condition that the display panel or the radar method fails, the display panel or the radar method can be conveniently opened for maintenance, and the situation that the display panel and the radar 132 are adhered to the display bracket 131 by the heat insulation layer and cannot be inspected and maintained is avoided.
