If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0026] In an embodiment of the present application, a refrigeration device is provided, which may be a device with storage and refrigeration functions, such as a refrigerator, a freezer, etc. The refrigeration device includes an inner container provided with a refrigerating space, and also includes a drawer 100 in any of the following embodiments. The drawer 100 is located in the refrigerating space and is used to hold the food ingredients to be refrigerated.

[0027] Referring to Figure 1 , Figure 1 , a schematic structural diagram of the drawer 100 in an embodiment of the present application is shown. The drawer 100 provided in an embodiment of the present application is used to hold food ingredients. In this specification, the drawer 100 is taken as an example applied to a refrigerator for illustration, but it is not limited. Combining Figure 2 as shown, Figure 2 , a schematic exploded structural diagram of the drawer 100 in an embodiment of the present application is shown. The drawer 100 includes a connected main body 110 and a panel 120. The main body 110 and the panel 120 jointly enclose a placement space 130 with an opening. The drawer 100 further includes a temperature measuring coating 140 coated on the main body 110 and / or the panel 120. In this embodiment, the temperature measuring coating 140 is coated on the panel 120. In other embodiments, the temperature measuring coating 140 can also be coated on the main body 110, and the temperature measuring effect can be achieved.

[0028] The temperature measuring coating 140 is made of a thermosensitive material. Within the normal temperature range, the color of the temperature measuring coating 140 will not change. Beyond the normal temperature range, the temperature measuring coating 140 will change color. The user can monitor whether the refrigerator temperature is within the normal range based on the color of the temperature measuring coating 140. Thermosensitive coatings, also known as thermochromic coatings, are a special type of coating that can respond to temperature changes and change color, producing a striking dynamic effect. The color change temperature sensitivity of thermosensitive coatings can be very precise. According to different application requirements, they can trigger color changes within a specific temperature range. The principle of thermosensitive coatings is that when the coating reaches a certain temperature, the temperature-sensitive pigments in the coating will undergo certain physical or chemical changes, resulting in changes in molecular structure and morphology, thereby causing changes in surface temperature, and indicating the temperature with color changes.

[0029] In this embodiment, a thermosensitive coating suitable for refrigerator temperature monitoring requirements can be selected. The thermosensitive coating is synthesized by a variety of ingredients. In this embodiment, the synthesized thermosensitive coating used meets the requirement of showing one color below 8°C. When the temperature is higher than 8°C, the material will change color.

[0030] Thermosensitive coatings are divided into reversible thermochromic and irreversible thermochromic. Optionally, in order to reduce the difficulty of later maintenance, reversible thermochromic is adopted in this embodiment, that is, when the ambient temperature of the drawer 100 increases, the temperature measuring coating 140 changes color, and when the ambient temperature of the drawer 100 drops to the initial temperature, the temperature measuring coating 140 restores the initial color.

[0031] like Figure 2 As shown, in one embodiment, the temperature measuring coating 140 is applied to the end face of the panel 120 facing the placement space 130, and the temperature measuring coating 140 faces the placement space 130 to monitor the temperature in the placement space 130, which is closer to the ambient temperature of the stored food, so that the temperature monitoring is more accurate. In other embodiments, the temperature measuring coating 140 can also be applied to any end face of the main body 110 facing the placement space 130. In other embodiments, the temperature measuring coating 140 can also be applied to the end faces of the main body 110 and the panel 120 away from the placement space 130. In this case, the measured temperature has a slight error compared to the end face set toward the placement space 130.

[0032] In one embodiment, the panel 120 is made of a transparent material so that the user can observe the color of the temperature measuring coating 140 from outside the drawer 100. In this embodiment, the temperature measuring coating 140 covers the entire end face of the panel 120 facing the placement space 130. In other embodiments, it may also be that the temperature measuring coating 140 covers a part of the end face of the panel 120 facing the placement space 130. At this time, the part of the panel 120 located at the temperature measuring coating 140 is made of a transparent material, and the color of the temperature measuring coating 140 can be observed from outside the drawer 100.

[0033] In the above solution, by applying the temperature measuring coating 140 on the main body 110 or the panel 120, and utilizing the characteristic that the change of the ambient temperature around the temperature measuring coating 140 will cause the temperature measuring coating 140 to change color, when the temperature inside the refrigerator rises, the temperature measuring coating 140 can change color to remind the user to pay attention to the change of the ambient temperature, and then feedback that the temperature of the refrigerator is abnormal, so as to monitor whether the temperature of the refrigerator is within the normal range. Compared with the prior art that uses a monitoring unit and an alarm device, this solution has a simple structure, low production cost and simple operation, and at the same time, there is no problem that the monitoring unit is unstable in a low-temperature environment.

[0034] As Figure 2 shown, in one embodiment, the main body 110 is provided with a groove 111 having a top opening 112 and a side opening 113. The main body 110 includes a bottom plate and side plates connected to the bottom plate and sequentially connected end to end, which jointly enclose a groove 111 having a top opening 112 and a side opening 113. The panel 120 is connected to the main body 110 and covers the side opening 113, so that the panel 120 and the main body 110 jointly enclose a placement space 130 having a top opening 112.

[0035] As Figure 2 shown, in one embodiment, the panel 120 is detachably connected to the main body 110 to facilitate the coating of the temperature measuring coating 140. In other embodiments, the panel 120 may also be fixedly connected to the main body 110.

[0036] As Figure 2 shown, in one embodiment, the main body 110 includes a first side wall 114 and a second side wall 115 arranged opposite to each other. Two ends of the panel 120 are respectively detachably connected to the first side wall 114 and the second side wall 115, so that the panel 120 covers the side opening 113 located between the first side wall 114 and the second side wall 115. In other embodiments, the end face of the panel 120 facing the placement space 130 may also be used to connect to the main body 110.

[0037] As Figure 2As shown, in one embodiment, connection blocks 121 are respectively protruded at both ends of the panel 120, and connection grooves 116 adapted to the connection blocks 121 are provided on both the first side wall 114 and the second side wall 115 of the main body 110. The connection blocks 121 are slidably connected to the connection grooves 116. The connection blocks 121 are inserted into the connection grooves 116 to connect the panel 120 and the main body 110, and the connection blocks 121 are removed from the connection grooves 116 to disassemble the panel 120.

[0038] In this embodiment, the panel 120 can slide relative to the main body 110 and then be fastened to the main body 110, as Figure 1 and Figure 2 shown, the main body 110 is provided with fastening holes 117, and the drawer 100 further includes fasteners for inserting into the fastening holes 117 to fasten the panel 120 and the main body 110.

[0039] In one embodiment, the sliding direction of the connection block 121 relative to the connection groove 116 is the up-and-down direction. When the drawer 100 moves relative to the refrigerator, the moving direction is usually the horizontal direction. The up-and-down direction is perpendicular to the horizontal direction to prevent the connection block 121 from moving when the drawer 100 is pulled, so as to ensure the stable connection between the panel 120 and the main body 110. In this embodiment, the connection grooves 116 are located at the tops of the first side wall 114 and the second side wall 115, and the connection grooves 116 have open tops to facilitate the insertion of the connection blocks 121.

[0040] As Figure 1 and Figure 2 shown, in one embodiment, a handle 122 is protruded on the end face of the panel 120 facing away from the placement space 130 to facilitate the pulling of the drawer 100.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
