The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0026] See also Figures 1 to 8 As shown, the present invention provides a refrigeration device 100, including a box body 1, a door body 2 for opening and closing the box body 1, the box body 1 and the door body 2 forming a refrigeration compartment, a heat preservation device 3 is arranged in the refrigeration compartment, the heat preservation device 3 includes a box body 31 with a receiving cavity, a cover body 32 for opening and closing the box body 31, the box body 31 is detachably connected to the box body 1, and the cover body 32 is detachably connected to the door body 2, so that the heat preservation device 3 forms an independent storage space, thereby preventing the food placed in the heat preservation device 3 from mixing with other food materials in the refrigeration device 100. Since the box body 31 is detachably connected to the box body 1, and the cover body 32 is detachably connected to the door body 2, the heat preservation device 3 can be taken out of the refrigeration compartment, and the cover body 32 can seal the box body 31, which is convenient for users to carry the heat preservation device 3, and can reduce the overflow of cold in the heat preservation device 3, so that the heat preservation device 3 has a longer heat preservation effect.

[0027] It is understandable that the refrigeration device 100 may be a common refrigeration device such as a refrigerator or a freezer, and the refrigeration device 100 has a refrigeration system inside, and provides cold energy to the refrigeration chamber through the refrigeration system. At the same time, the heat preservation device 3 obtains the cold energy in the refrigeration chamber to cool down the food or articles in the containing cavity and prolong the storage period of the food or articles.

[0028] In the present invention, when the heat preservation device 3 is placed in the refrigeration room, the box body 31 of the heat preservation device 3 is connected to the box body 1 of the refrigeration device 100, and the cover body 32 of the heat preservation device 3 is connected to the door body 2 of the refrigeration device 100. In addition, the cover body 32 and the door body 2 move synchronously. When the door body 2 of the refrigeration device 100 is opened, the cover body 32 of the heat preservation device 3 is also opened, so that it is convenient for users to take and put items in the heat preservation device 3. When the door body 2 of the refrigeration device 100 is closed, the cover body 32 of the heat preservation device 3 is also closed, so as to keep the heat preservation device 3 to form a closed storage space to avoid odor contamination.

[0029] Furthermore, the box body 31 and the cover body 32 of the heat preservation device 3 can be made of heat preservation materials, for example, the box body 31 and the cover body 32 are filled with foam material or a vacuum insulation panel is arranged inside, so that when the heat preservation device 3 is taken out of the refrigeration chamber, the cold overflow in the heat preservation device 3 is further reduced, so that the heat preservation device 3 has a longer heat preservation effect.

[0030] Furthermore, a positioning assembly 4 for detachably connecting the cover body 32 to the door body 2 is provided between the cover body 32 and the door body 2 , and the user can conveniently lock or separate the cover body 32 and the door body 2 by adjusting the positioning assembly 4 .

[0031] Specifically, see Figure 3 and Figure 4 As shown, the positioning assembly 4 includes a slot 41 provided on the side of the cover body 32 facing the door body 2, and a hook 42 movably connected to the door body 2 in the extending direction of the slot 41, and the door body 2 and the cover body 32 are locked or separated by the cooperation of the hook 42 and the slot 41. It can be understood that the hook 42 moves on the door body 2 in the extending direction of the slot 41, so that the hook 42 and the slot 41 are locked or unlocked.

[0032] It is understandable that, in the present invention, the positioning assembly 4 may include a plurality of groups of hooks 42 and slots 41 , and the number and positions of the hooks 42 and slots 41 correspond to each other, thereby improving the reliability of the connection between the cover body 32 and the door body 2 .

[0033] Furthermore, the slot 41 includes a guide portion and a locking portion, and the hook 42 has an unlocking position that cooperates with the guide portion and a locking position that cooperates with the locking portion; it can be understood that the guide portion and the locking portion are arranged along the extension direction of the slot 41.

[0034] In a specific embodiment, the positioning assembly 4 includes two groups of hooks 42 and slots 41 arranged at intervals in the horizontal direction, and the slots 41 extend in the vertical direction, and the guide portion and the locking portion are arranged in the vertical direction. Specifically, the guide portion is located above the locking portion, and the locking portion is located at the lower end of the slot 41. The hook 42 can controllably slide up and down in the slot 41. When the hook 42 is in the unlocked position cooperating with the guide portion, the cover body 32 and the door body 2 are in an unlocked state. When the hook 42 is moved downward so that the hook 42 cooperates with the locking portion, the hook 42 is in the locked position, and the cover body 32 and the door body 2 are in a locked state. Specifically, the locking portion is the bottom of the slot 41.

[0035] Furthermore, the positioning assembly 4 also includes an adjustment plate 43 fixedly connected to the hook 42; the door body 2 is provided with a first accommodating groove 21 for moving the adjustment plate 43 along the extension direction of the slot 41, and a second accommodating groove 22 for moving the hook 42 along the extension direction of the slot 41. The user moves the adjustment plate 43 to make the adjustment plate 43 slide in the first accommodating groove 21, and makes the hook 42 slide in the second accommodating groove 22 and the slot 41, so as to realize the switching of the hook 42 between the unlocked position and the locked position, and finally realizes the switching of the cover body 32 and the door body 2 between the unlocked state and the locked state.

[0036] Specifically, the first receiving groove 21 and the second receiving groove 22 are connected, and the first receiving groove 21 is arranged inside the door body 2, so that the adjustment plate 43 is located inside the door body 2, which does not damage the aesthetics of the door body 2 of the refrigeration device 100 and can also enhance the strength of the door body 2. In addition, the second receiving groove 22 is arranged on the side of the door body 2 facing the box body 1, so that the hook 42 passes through the second receiving groove 22 and cooperates with the slot 41 on the cover body 32.

[0037] In one specific embodiment, see Figure 8 As shown, adjustment handles 431 are fixedly provided at both ends of the adjustment plate 43, and avoidance grooves connected to the first accommodating groove 21 are provided on the left and right end sides of the door body 2, and the adjustment handles 431 are located in the corresponding avoidance grooves, so that the user can easily move the hook 42 along the extension direction of the groove 41 by adjusting the adjustment handles 431 on both sides at the same time, and finally realize the switching of the cover body 32 and the door body 2 between the unlocked state and the locked state.

[0038] Further, the adjusting plate 43 and / or the hook 42 are made of a magnetic metal, and a limiting magnet 15 is provided on the end side of the first receiving groove 21 corresponding to the guide portion. Figure 8As shown, the limiting magnet 15 holds the adjusting plate 43 and the hook 42 in the unlocked position where the hook 42 cooperates with the guide portion, so that the user can remove the cover 32 from the door 2 and use the heat preservation device 3 alone outside the ice-making device.

[0039] Furthermore, the positioning assembly 4 includes a plurality of first positioning magnets 44 disposed on the door body 2, and a plurality of second positioning magnets 45 disposed on the side of the cover body 32 facing the door body 2, wherein the second positioning magnets 45 correspond to the first positioning magnets 44 one by one, and the detachable connection between the door body 2 and the cover body 32 is achieved through the cooperation between the first positioning magnets 44 and the second positioning magnets 45. Of course, it is understandable that the present invention can simultaneously adopt the hook 42 and the slot 41, the first positioning magnet 44 and the second positioning magnet 45 to cooperate to achieve the detachable connection between the door body 2 and the cover body 32.

[0040] Furthermore, the box body 1 is provided with an air inlet channel and an air return channel, and an air inlet portion 5 connected to the air inlet channel and an air return portion 6 connected to the air return channel are convexly provided on the inner wall of the box body 1; the box body 31 is provided with an air inlet 7 connected to the air inlet portion 5, an air return portion 8 connected to the air return portion 6, a first air door 9 rotatably connected to the air inlet 7, and a second air door 10 rotatably connected to the air return portion 8, and an automatic reset mechanism is provided on the first air door 9 and the second air door 10. When the box body 31 is placed in the refrigeration room, the air inlet portion 5 and the air return portion 6 convexly provided on the inner wall of the box body 1 are connected to the air inlet 7 and the air return portion 8 respectively, the first air door 9 is pushed open by the air inlet portion 5, and the second air door 10 is pushed open by the air return portion 6, so that the interior of the heat preservation device 3 is connected to the air inlet channel and the air return channel at the same time, so that an air path is formed inside the heat preservation device 3 and the cooling capacity of the refrigeration device 100 is quickly obtained. When the heat preservation device 3 is taken out from the refrigeration room, the air inlet 5 and the air outlet are separated from the air inlet 7 and the return air outlet 8 respectively. Under the action of the automatic reset mechanism, the first air door 9 and the second air door 10 are automatically reset to seal the air inlet 7 and the return air outlet 8 respectively, so that the heat preservation device 3 forms a closed storage space, reduces the overflow of internal cold, and ensures the cooling or heat preservation effect of the heat preservation device 3.

[0041] It is understandable that both the first damper 9 and the second damper 10 are provided with an automatic reset mechanism. Specifically, the automatic reset mechanism is a spring reset member and / or a magnetic member, and the spring reset member is connected to the inner wall of the box body 31, and is also connected to the corresponding first damper 9 or second damper 10. Of course, it is understandable that when the automatic reset mechanism is a magnetic member, the first damper 9 and the box body 31 are provided with magnetic members that attract each other, so that the first damper 9 automatically resets to the sealed air inlet 7 without the adjustment of external interference. It is understandable that the way of providing the magnetic member on the second damper 10 is the same as this, and no further description is given.

[0042] Furthermore, the heat preservation device 3 also includes a plurality of third positioning magnets 11 arranged on the side of the cover body 32 facing the box body 31, and a plurality of fourth positioning magnets 12 arranged on the side of the box body 31 facing the cover body 32. The fourth positioning magnets 12 correspond one-to-one to the third positioning magnets 11, so that the box body 31 and the cover body 32 are detachably connected.

[0043] It is understandable that when the heat preservation device 3 is located in the refrigeration room, when the door body 2 of the refrigeration equipment 100 is closed, the cover body 32 seals the box body 31 through the cooperation of the third positioning magnet 11 and the fourth positioning magnet 12, so that the heat preservation device 3 forms a sealed storage space. When the door body 2 of the refrigeration equipment 100 is opened, the positioning assembly 4 overcomes the attraction between the third positioning magnet 11 and the fourth positioning magnet 12, so that the cover body 32 moves synchronously with the door body 2, thereby facilitating the user to take and put items. When the heat preservation device 3 is independent of the refrigeration equipment 100, the cover body 32 seals the box body 31 through the cooperation of the third positioning magnet 11 and the fourth positioning magnet 12, so that the heat preservation device 3 forms a sealed storage space.

[0044] Furthermore, one of the box body 31 and the cover body 32 is convexly provided with a positioning column 13, and the other is concavely provided with a positioning groove 14 corresponding to the positioning column 13. Through the cooperation of the positioning column 13 and the positioning groove 14, it is convenient to assemble the box body 31 and the cover body 32 together, and at the same time, it can avoid the problem of the cover body 32 being installed upside down or incorrectly.

[0045] The refrigeration compartment of the refrigeration device 100 of the present invention is provided with a heat preservation device 3, which includes a box body 31 having a receiving cavity and a cover body 32 for opening and closing the box body 31, so that the heat preservation device 3 forms an independent storage space, thereby preventing the food placed in the heat preservation device 3 from mixing with other food materials in the refrigeration device 100. Since the box body 31 is detachably connected to the box body 1, and the cover body 32 is detachably connected to the door body 2, when the heat preservation device 3 is taken out of the refrigeration compartment, the cover body 32 seals the box body 31, which is convenient for users to carry the heat preservation device 3, and can also reduce the overflow of cold in the heat preservation device 3, so that the heat preservation device 3 has a longer heat preservation effect.
