[0002] In the existing refrigerators that are both equipped with ice cream devices, the refrigerator cold storage room and the ice cream device each use an evaporator, resulting in high product costs. For example, Chinese Patent No. ZL201610312390.5 discloses a refrigerator with an ice cream machine, which relates to the field of refrigerator technology and is invented to solve the problem of inconvenience in taking ice cream cups in the prior art. The refrigerator has an ice cream machine, which is placed in the refrigerator cold storage room of the refrigerator. The ice cream machine includes a box body and a door body for opening and closing the box body. An ice cream cup assembly and an ice cream evaporator are arranged in the box body. The ice cream cup assembly is detachably connected to the box body, and the ice cream evaporator is connected to the refrigeration circuit of the refrigerator.

[0003] The ice cream machine is located in the cold storage compartment of the refrigerator and also occupies the space of the cold storage compartment of the refrigerator. Utility Model Content

[0004] The utility model aims to provide an integrated refrigerator and ice cream machine, in which a refrigerator liner and an ice cream device are independently arranged in a box body on the left and right or up and down, eliminating the structural mode of placing the ice cream device in the refrigerator liner, and the refrigerator liner and the ice cream device share a refrigeration device, so that the product cost is low and the product volume is small.

[0005] The purpose of the utility model is achieved in this way:

[0006] A refrigerator and ice cream integrated machine comprises a box body, a refrigerator liner and an ice cream device for making ice cream are arranged in the box body, a refrigeration device acting on the refrigerator liner and the ice cream device is arranged in the box body, and the refrigerator liner and the ice cream device are independently arranged in the box body in the left and right or up and down directions and share a refrigeration device. The structural mode of placing the ice cream device in the refrigerator liner is eliminated, and the space of the refrigerator liner is not occupied when the ice cream device is added. The refrigerator liner and the ice cream device share a refrigeration device, and the product cost is low, the product volume is small, and the occupied space is small.

[0007] The refrigeration device includes a compressor, a condenser, and an evaporator which are connected in sequence by pipelines. A refrigerator liner heat exchanger is provided on the refrigerator liner. The ice cream device includes an ice cream heat exchanger. One end of the refrigerator liner heat exchanger and the ice cream heat exchanger are connected to the evaporator through pipelines respectively, and the other ends of the liner heat exchanger and the ice cream heat exchanger are connected to the compressor through pipelines respectively.

[0008] When the refrigerator liner is refrigerating, the compressor, condenser, evaporator, and refrigerator liner heat exchanger form a refrigerator refrigeration circuit; the compressor starts working, and the low-temperature, low-pressure refrigerant is sucked into the compressor. The refrigerant is compressed into a high-temperature, high-pressure superheated gas in the compressor cylinder and then enters the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continues to drop, and is gradually cooled to a saturated vapor at normal temperature and high pressure. The condensed refrigerant saturated liquid is filtered through the dry filter to remove moisture and impurities and flows into the capillary tube, through which throttling and pressure reduction are performed, and the refrigerant becomes a wet vapor at normal temperature and low pressure. The refrigerant enters the evaporator, and the refrigerant then begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator enters the refrigerator liner heat exchanger to exchange heat with the refrigerator liner. After the heat exchange, the refrigerant returns to the compressor again, repeating the above process to transfer the heat of the refrigerator liner to the outside air of the box, achieving the purpose of refrigeration.

[0009] When the ice cream device is refrigerating, the compressor, condenser, evaporator, and ice cream heat exchanger form a refrigerator refrigeration circuit; so that the refrigerator liner and the ice cream device share a compressor, condenser, and evaporator. The compressor starts working, and the low-temperature, low-pressure refrigerant is sucked into the compressor. The refrigerant is compressed into a high-temperature, high-pressure superheated gas in the compressor cylinder and then enters the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continues to drop, and is gradually cooled to a saturated vapor at normal temperature and high pressure. The condensed refrigerant saturated liquid is filtered out of water and impurities by the drying filter and flows into the capillary tube, through which it is throttled and reduced in pressure, and the refrigerant becomes a wet vapor at normal temperature and low pressure. The refrigerant enters the evaporator, and the refrigerant then begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator enters the ice cream heat exchanger and exchanges heat with the mixing container of the ice cream device. After the heat exchange, the refrigerant returns to the compressor again, and the above process is repeated to transfer the heat of the mixing container of the ice cream device to the outside air of the box, thereby achieving the purpose of refrigeration.

[0014] When starting to make ice cream, one only needs to open the cover and place ice cream ingredients on the mixing container; when mixing is completed, one only needs to open the cover to take out the prepared ice cream.

[0015] A stirrer is arranged in the stirring container, and the stirrer and the stirring container are arranged as a whole. A driving assembly connected to the stirring container is arranged in the box body, and the driving assembly drives the stirring container and the stirrer to perform circumferential rotation motion together.

[0016] The stirrer is vertically arranged on a support shaft on the stirring container, and connecting cross bars are respectively extended at both ends of the support shaft. A first stirring block is arranged at one end of the connecting cross bar, and a plurality of stirring teeth are arranged on the first stirring block. A second stirring block with a gradual thickness is arranged at the other end of the connecting cross bar.

[0017] The ends of the connecting crossbar are provided with a first stirring block and a second stirring block, which effectively increase the stirring area and allow the ice cream ingredients to be fully mixed.
