[0045] like Figure 1-8 As shown, a bag refrigerator for keeping food cold outdoors includes
[0046] The luggage body 1 is used for refrigerating items;
[0047] The luggage body 1 includes a bottom bracket assembly 2 arranged at the bottom of the luggage body 1;
[0048] A refrigeration assembly 3 is provided in the bottom bracket assembly 2 and cools the luggage body 1;
[0049] The refrigeration assembly 3 includes a compressor 301 and a condenser 302 respectively disposed in the bottom support assembly 2;
[0050] The lower end portion of the bag body 1 is provided with an air inlet 201 and an air outlet 202 for air flow to dissipate heat from the compressor 301 and the condenser 302 .
[0051] In this case, a refrigeration component 3 is set at the bottom of the bag body 1, which can continuously cool the bag body 1, so that food and drinks can be kept in a low-temperature refrigerated state for a long time, meeting the user's demand for refrigerated food during self-driving tours or outdoor activities. At the same time, it can maximize the capacity of the bag body 1, lower the overall center of gravity, and prevent the bag refrigerator from falling.
[0052] In this embodiment, the air inlet 201 and the air outlet 202 are preferably provided at the bottom of the bottom bracket assembly 2. During the cooling process of the refrigeration assembly 3, outside air can enter the bottom bracket assembly 2 through the air inlet 201, pass through the compressor 301 and the condenser 302, and be discharged through the air outlet 202, thereby dissipating heat from the compressor 301 and the condenser 302.
[0053] like Figure 3-6 As shown, the bottom bracket assembly 2 includes
[0054] The bottom shell 203 has a receiving cavity 2031 therein, and the air inlet 201 and the air outlet 202 are respectively provided at the bottom of the bottom shell 203;
[0055] The support bracket 204 is disposed in the accommodating cavity 2031 , and the upper end of the support bracket 204 contacts the bag body 1 , or the lower end of the support bracket 204 contacts the inner bottom surface of the bottom shell 203 ;
[0056] The compressor 301 and the condenser 302 are respectively fixed on the support bracket 204 .
[0057] In this case, the bottom shell 203 of the bottom bracket assembly 2 supports the refrigerator case; the supporting bracket 204 connects the bottom shell 203 to the main body 1 of the case, and simultaneously secures the compressor 301 and condenser 302 to the bottom shell 203. During heat dissipation, outside air can enter the accommodating chamber 2031 through the air inlet 201, dissipate heat from the compressor 301 and condenser 302, and then exit the accommodating chamber 2031 through the air outlet 202, thereby improving the heat dissipation effect.
[0058] like Figure 3-4 As shown, the refrigeration component 3 also includes
[0059] The evaporator 303 is in contact with the bag body 1, the input end of the compressor 301 is connected to one end of the evaporator 303, and the two ends of the condenser 302 are respectively connected to the other end of the evaporator 303 and the output end of the compressor 301;
[0060] The cooling fan 304 is connected to the condenser 302 , and the air outlet of the cooling fan 304 faces the air outlet 202 .
[0061] In this case, a cooling fan 304 is provided to accelerate air flow and improve the heat dissipation effect of the condenser 302, thereby reducing the volume of the condenser 302 and reducing the overall volume of the luggage refrigerator.
[0062] like Figure 3-5As shown, a partition plate 4 is provided within the accommodating chamber 2031 between the air inlet 201 and the air outlet 202, and a cooling fan 304 is disposed on the partition plate 4. In this embodiment, the partition plate 4 divides the accommodating chamber 2031 into two independent chambers, with the air inlet 201 and the air outlet 202 disposed in the two independent chambers, respectively. During the heat dissipation process, air enters one independent chamber of the accommodating chamber 2031 through the air inlet 201. Under the action of the cooling fan 304, the air dissipates heat from the compressor 301 and condenser 302, then passes through the partition plate 4 into the independent chamber on the other side of the accommodating chamber 2031, and is finally discharged from the air outlet 202, further improving the heat dissipation effect.
[0063] like Figure 1 As shown, the bottom surface of the bag body 1 is provided with support feet 5 connected to the bottom of the bottom shell 203. In this case, the support feet 5 are provided so that when the bag refrigerator is placed on the ground, a gap can be set between the bag refrigerator and the ground, allowing outside air to enter and exit the accommodating cavity 2031 for heat dissipation.
[0064] like Figure 2-4 As shown, the bag body 1 includes
[0065] The inner liner 101 is provided with at least one freezing chamber 1011 for refrigerating items. The upper end of the support bracket 204 is connected to the bottom of the inner liner 101, and the evaporator 303 is in contact with the inner liner 101.
[0066] The thermal insulation layer 102 is sleeved on the outer surface of the inner liner 101;
[0067] The outer skin layer 103 is sleeved on the outer sides of the thermal insulation layer 102 and the bottom shell 203;
[0068] The box cover 104 covers the inner container 101 and the insulation layer 102 to seal the freezing chamber 1011.
[0069] In this case, outer skin layer air inlet holes 1031 and outer skin layer air outlet holes 1032 are respectively provided on the bottom surface of the outer skin layer 103 at positions corresponding to the air inlet holes 201 and the air outlet holes 202, so as to facilitate air to enter and exit the accommodating cavity 301 through the outer skin layer 103 for heat dissipation.
[0070] In this case, outer layer 103 is wrapped around insulation layer 102 and the outside of bottom shell 203 of bottom bracket assembly 2, forming an integral unit with inner liner 101, insulation layer 102, and bottom shell 203. This simplifies the overall structure of the refrigerator and significantly reduces the weight of the refrigerator by replacing traditional metal with outer layer 103. Furthermore, inner liner 101 is a plastic liner, insulation layer 102 is a polyurethane foam layer, outer layer 103 is a polyurethane outer layer, and lid 104 is a polyurethane lid.
[0071] like Figure 3-6 As shown, the insulation layer 102 includes a side layer and a bottom layer, and the upper end of the support bracket 204 is embedded in the insulation layer 102 and contacts the bottom of the inner liner 101; the side of the support bracket 204 is provided with a plurality of support bracket bent portions 2045 extending outward to press against the inner side of the bottom shell 203; the support bracket 204 includes a bracket base 2041, and the bracket base 2041 is provided with a plurality of support rod groups 2042, the support rod group 2042 is composed of two support rods 2043, and a support frame 2044 embedded in the insulation layer 102 and in contact with the bottom of the inner liner 101 is connected between the upper ends of the two support rods 2043 on the support rod group 2042, and the support frame bent portions 2045 are arranged at both ends of the support frame 2044.
[0072] In this case, the support frame 2044 of the bottom bracket assembly 2 is embedded in the insulation layer 2 and supports the inner liner 104, so that the inner liner 104, the insulation layer 012 and the bottom shell 2041 are connected as a whole. At the same time, the compressor 301, the condenser 302, and the cooling fan 304 are respectively fixed to the bottom shell 203 through the bracket base 2041. On the other hand, the support frame bent portion 2045 of the bottom bracket assembly 2 is pressed against the inner wall of the bottom shell 203 to open the bottom shell 203 from the inside, ensuring that the bottom shell 203 will not deform, while also ensuring that the outer skin 103 is opened. In this case, the bottom shell 203 is a plastic bottom shell, and the bottom bracket assembly 2 is connected by sheet metal rods. By using the above-mentioned lightweight materials, the weight of the luggage refrigerator is further reduced, and the luggage refrigerator is lightweight and easy to carry and move.
[0073] In this case, the plastic liner makes the liner lightweight, impact-resistant, durable and waterproof; the polyurethane foam layer makes the insulation layer lightweight and highly efficient insulated, ensuring that the food and beverages in the freezing chamber of the liner remain at a low temperature for a long time; the polyurethane outer layer makes the outer layer waterproof and wear-resistant, which can well protect the internal insulation layer and bottom bracket assembly; the polyurethane box cover makes the box cover lightweight, heat-insulating and durable, ensuring good insulation effect after the inner liner is closed to seal the freezing chamber.
[0074] In this embodiment, evaporator 303 contacts inner container 101 to cool freezing chamber 1011. Furthermore, evaporator 303 surrounds the outer wall of inner container 101, increasing the contact area between the two and significantly improving the cooling effect of freezing chamber 101. Similarly, this embodiment can also utilize plate and tube cooling, inflation cooling, or air cooling to cool the freezing chamber of the inner container.
[0075] like Figure 7-8As shown, a locking assembly 6 for fixing an external battery is provided on the outside of the outer layer 103. In this case, the locking assembly 6 can be an elastic cord, a storage bag, or a buckle for accommodating or hanging the external battery. A power supply interface 7 is provided on one side of the bottom shell 203, which passes through the outer layer 103 and is electrically connected to the external battery for supplying power to the refrigeration component 3. In this case, the external battery is connected to the power supply interface 7 via a connecting line to supply power to the internal electrical components of the luggage refrigerator. A touch panel assembly 8 is provided on the lower side of the front side of the bottom shell 203, which passes through the outer layer 103 and is used to set and display the temperature. In this case, a touch panel is used for temperature adjustment, allowing users to intuitively set the temperature inside the refrigerator, making operation simple and quick.
[0076] like Figure 7-8 As shown, in this case, the rear side of the outer layer 103 is provided with a shoulder strap 9, a chest strap 10 and a waist strap 11, which can enable the luggage refrigerator to be carried firmly on the user's back; in this case, the rear side of the outer layer 103 is provided with a back pad 12 to improve the comfort of carrying the backpack; in this case, the side of the outer layer 103 is provided with a side pocket 13 for placing small items; in this case, the side of the outer layer 103 is provided with a luggage buckle 14 for lifting the luggage refrigerator or hanging small items; in this case, the top surface of the box cover 104 is provided with a box cover handle 15 to facilitate opening the box cover 104.
