Description

Technical Field

[0001] This utility model relates to the field of liquid cryogenic molding technology, and in particular to a liquid cryogenic device. Background Technology

[0002] With social development and the continuous improvement of living standards, more and more people like to make various ice products at home. For example, in the hot summer, people often make ice cubes or popsicles at home. When making ice cubes or popsicles, people need to add water or materials in liquid state into the cavity of the freezing mold, and then put it into the freezing cavity of the liquid freezing equipment for freezing.

[0003] While the aforementioned cryogenic molding molds can meet users' needs for making ice cubes or popsicles, when these molds are placed in the freezing chamber of the liquid freezing equipment, the outer wall of the mold cannot fit tightly against the inner wall of the freezing chamber. Therefore, a gap exists between the mold and the inner wall of the freezing chamber, containing air. This affects the heat conduction between the freezing chamber and the mold, significantly reducing the freezing efficiency of the liquid freezing equipment. This greatly extends the freezing time of the liquid freezing equipment and requires more electricity, resulting in a significant increase in the production cost of ice products. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a liquid freezing device that allows the sidewall of the freezing mold to better adhere to the inner sidewall of the freezing chamber of the liquid freezing device. This helps improve the thermal conductivity between the freezing mold and the freezing chamber of the liquid freezing device, thus shortening the time for producing ice products and reducing the energy consumption of the liquid freezing device.

[0005] A liquid freezing device according to an embodiment of the present invention includes a liquid freezing device body and one or more cryogenic molding molds. The liquid freezing device body is provided with a compressor, a condenser, an evaporator, and a control system. The compressor, the condenser, and the evaporator are connected in series via pipes to form a circulation channel for refrigerant circulation. The control system is electrically connected to the compressor. The evaporator has one or more freezing chambers inside. The side wall of the liquid freezing device body has an opening communicating with the freezing chamber. The cryogenic molding mold can pass through the opening and be detachably inserted into the freezing chamber. The cryogenic molding mold includes a first shell and a second shell. One end of the first shell is a first movable end, and one end of the second shell is a second movable end. The first movable end and the second movable end are movable. The first housing and the second housing are connected and can rotate relative to each other to fit together or separate. The first housing has a first chamber with an opening facing the second housing. When the first housing and the second housing are fitted together, the first chamber and the second housing can cooperate to form a sealed receiving cavity. The bottom wall of the first chamber away from the second housing is a first side wall, and the side wall of the second housing at the corresponding position to the first chamber is a second side wall. The first side wall is a flexible side wall that can deform under force, and / or the second side wall is a flexible side wall that can deform under force. When the cryogenic molding mold is inserted into the freezing cavity, the liquid loaded inside the receiving cavity squeezes the first side wall and the second side wall, causing the first side wall and / or the second side wall to protrude outward and fit tightly against the inner side wall of the freezing cavity.

[0006] A liquid freezing device according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] This embodiment of a liquid freezing device uses a freeze-forming mold with first and / or second sidewalls that are flexible and deformable under stress. The user pours the liquid to be used to make ice products into the receiving cavity of the freeze-forming mold, and then places the mold into the freezing cavity of the liquid freezing device. Because the first and / or second sidewalls are flexible and deformable under stress, the liquid inside the receiving cavity, under the influence of gravity, pushes the first and / or second sidewalls outward, causing them to press tightly against the inner wall of the freezing cavity. Therefore, when making ice products, the freeze-forming mold fits more closely to the inner wall of the evaporator's freezing cavity, improving the thermal conductivity between the freeze-forming mold and the freezing cavity, and allowing for greater cooling capacity. The efficient transfer of liquid to the freezing mold significantly shortens the time required for producing ice products in liquid freezing equipment, helps reduce energy consumption, and thus lowers production costs for users. Furthermore, the freezing mold in this embodiment is detachably inserted into the freezing chamber of the liquid freezing equipment. After ice production is complete, the user can remove the freezing mold separately for cleaning without moving the entire liquid freezing equipment, making cleaning more convenient and efficient. Additionally, the freezing mold's cavity can be made in various shapes. Users can pour the liquid to be used into the freezing mold's cavity and then place the freezing mold in the freezing chamber of the liquid freezing equipment for freezing, thus producing ice products of different shapes to meet users' personalized needs for creating ice products of various shapes.

[0035] Reference Figures 1 to 12 and mainly refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9According to certain embodiments of the present invention, a liquid refrigeration device is sometimes referred to as a "liquid refrigeration device". A liquid refrigeration device includes a liquid refrigeration device body 100 and one or more cryogenic molding dies 200. In this embodiment, the liquid refrigeration device body 100 is generally rectangular in shape. The liquid refrigeration device body 100 includes an outer shell 101, and an installation cavity 102 is provided inside the outer shell 101. A compressor 110, a condenser 120, an evaporator 130, and a control system 140 are arranged inside the installation cavity 102. The compressor 110, condenser 120, and evaporator 130 are connected in series via pipes to form a circulation channel for the refrigerant to circulate. The circulation channel is also provided with capillary tubes, thermal expansion valves, gas-liquid separators, etc. Since this technical solution is known in the art, it will not be described in detail here. The control system 140 is electrically connected to the compressor 110. The evaporator 130 has one or more freezing chambers 150. In this embodiment, the evaporator 130 has one freezing chamber 150, and the cryogenic molding molds 200 have four. The outer shell 101 of the liquid refrigeration equipment body 100 has an opening 151 on its side wall that communicates with the freezing chamber 150. The cryogenic molding molds 200 can pass through the opening 151 of the outer shell 101 and be detachably inserted into the freezing chamber 150. In this embodiment, the cryogenic molding mold 200 includes a first shell 210 and a second shell 220. One end of the first shell 210 is a first movable end 211, and one end of the second shell 220 is a second movable end 221. The first movable end 211 and the second movable end 221 are movably connected. The first shell 210 and the second shell 220 can rotate relative to each other to fit together or separate. The first shell 210 has a first chamber 212 with an opening facing the second shell 220. When the first shell 210 and the second shell 220 fit together, the first chamber 212 and the second shell 220 can cooperate to enclose and form a sealed receiving cavity. The receiving cavity is used to load the liquid to be made into ice products, such as water for making ice cubes or liquid materials for making popsicles. The bottom wall of the first chamber 212 away from the second housing 220 is the first side wall 213, and the side wall of the second housing 220 at the corresponding position to the first chamber 212 is the second side wall 223. The first side wall 213 is a flexible side wall that can deform under force, and / or the second side wall 223 is a flexible side wall that can deform under force. When the cryogenic molding mold 200 is inserted into the freezing cavity 150, the liquid loaded inside the cavity squeezes the first side wall 213 and the second side wall 223, causing the first side wall 213 and / or the second side wall 223 to protrude outward and fit tightly against the inner side wall of the freezing cavity 150.

[0036] In this embodiment, the liquid freezing device uses a first sidewall 213 and / or second sidewall 223 of the cryogenic molding mold 200 as flexible sidewalls that can deform under stress. Therefore, the user pours the liquid to be made into the receiving cavity of the cryogenic molding mold 200, and then places the cryogenic molding mold 200 into the freezing cavity 150 of the liquid freezing device. Because the first sidewall 213 and / or second sidewall 223 are flexible sidewalls that can deform under stress, the liquid inside the receiving cavity, under the action of gravity, squeezes the first sidewall 213 and / or second sidewall 223 outwards, causing it to arch and protrude. The side wall 213 and / or the second side wall 223 are in close contact with the inner side wall of the freezing chamber 150 of the liquid freezing equipment. Therefore, when the liquid freezing equipment of this embodiment is making ice products, the freezing mold 200 can fit more tightly with the inner side wall of the freezing chamber 150 of the evaporator 130, which improves the thermal conductivity between the freezing mold 200 and the freezing chamber 150 of the liquid freezing equipment. The cold energy of the freezing chamber 150 can be better transferred to the freezing mold 200, which greatly shortens the time for the liquid freezing equipment to make ice products, helps to reduce the energy consumption of the liquid freezing equipment, and thus reduces the production cost of ice products for users. Meanwhile, the cryogenic molding mold 200 of this embodiment is detachably inserted into the freezing chamber 150 of the liquid freezing equipment. After the ice products are made, the user can remove the cryogenic molding mold 200 separately for cleaning without having to move the entire liquid freezing equipment for cleaning. This makes cleaning more convenient and quick, and facilitates the user's use of the liquid freezing equipment to make ice products. In addition, the receiving cavity of the cryogenic molding mold 200 of this embodiment can be made into different shapes. Therefore, the user pours the liquid to be made into the receiving cavity of the cryogenic molding mold 200, and then places the cryogenic molding mold 200 into the freezing chamber 150 of the liquid freezing equipment for freezing, so as to make ice products of different shapes and meet the user's personalized needs for making ice products of different shapes.

[0037] It should be noted that in the above embodiment, the number of freezing chambers 150 provided inside the evaporator 130 is one, and the number of freezing molding molds 200 is four. However, in other embodiments of this utility model, the number of freezing chambers 150 provided inside the evaporator 130 can be set to two, three or more, and the number of freezing molding molds 200 can be set to one, two, three or more, depending on the actual situation.

[0038] Reference Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11In some embodiments of this invention, the second housing 220 has a second chamber 222 open towards the first housing 210, and a second sidewall 223 is the bottom wall of the second chamber 222 away from the first housing 210. When the first housing 210 and the second housing 220 are fitted together, the first chamber 212 and the second chamber 222 can cooperate to form a sealed receiving cavity. By adopting the above structure, the volume of the receiving cavity in this embodiment can be made larger, so as to accommodate more solution.

[0039] In some embodiments of this utility model, the first housing 210 has a first communication port 214 communicating with the first chamber 212 on its side wall away from the second housing 220, and the first side wall 213 is a first flexible membrane disposed on the first housing 210 and capable of sealing the first communication port 214; the second housing 220 has a second communication port 224 communicating with the second chamber 222 on its side wall away from the first housing 210, and the second side wall 223 is a second flexible membrane disposed on the second housing 220 and capable of sealing the second communication port 224. By adopting the above structure, the first housing 210 and the second housing 220 can be made of rigid materials, such as stainless steel, while the first side wall 213 and the second side wall 223 can be made of soft flexible materials, such as silicone or rubber, making the first and second flexible membranes more convenient to manufacture.

[0040] In some embodiments of this utility model, the first flexible membrane and the first housing 210 are an integral structure, and the second flexible membrane and the second housing 220 are an integral structure. Specifically, the first flexible membrane and the first housing 210 are injection molded, and the second flexible membrane and the second housing 220 are injection molded. By adopting the above structure, when manufacturing the first housing 210 and the second housing 220, enterprises can use food-grade rigid plastic to injection mold the first housing 210 and the second housing 220, and then use food-grade silicone or rubber to injection mold the first sidewall 213 and the second sidewall 223 onto the first housing 210 and the second housing 220. This not only improves the production efficiency of the first housing 210 and the second housing 220 and helps to reduce production costs, but also makes the connection between the first flexible membrane and the first housing 210 and the connection between the second flexible membrane and the second housing 220 tighter.

[0041] In some embodiments of this invention, the first flexible diaphragm and the first housing 210 are detachably connected, and the second flexible diaphragm and the second housing 220 are detachably connected. Therefore, the manufacturer can produce the first housing 210 and the second housing 220 separately using rigid materials, and fabricate the first and second flexible diaphragms using soft, flexible materials. Then, the first and second flexible diaphragms are fitted one-to-one into the first housing 210 and the second housing 220. By adopting the above structure, if any part of the first flexible diaphragm, the second flexible diaphragm, the first housing 210, or the second housing 220 is damaged, it can be replaced individually, facilitating maintenance.

[0042] Reference Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 In some embodiments of this utility model, the other end of the first housing 210 is a first fixed end 215, and the other end of the second housing 220 is a second fixed end 225. A locking assembly is provided between the first fixed end 215 and the second fixed end 225. The locking assembly can lock the first fixed end 215 and the second fixed end 225 and restrict the relative rotation and separation of the first housing 210 and the second housing 220. Specifically, the locking assembly includes a hook 310 and a locking member 320 that can engage with each other. The locking member 320 has a groove 321 that engages with the hook 310. The hook 310 is rotatably mounted on the second fixed end 225 of the second housing 220. The second fixed end 225 is provided with a torsion spring for driving the hook 310 to maintain the engaged state. The snap-fit ​​element 320 is disposed at the first fixed end 215 of the first housing 210. When the first housing 210 and the second housing 220 rotate relative to each other and fit together, the snap hook 310 snaps into the slot 321 of the snap-fit ​​element 320. At this time, the snap hook 310 and the snap-fit ​​element 320 cooperate to snap together and lock the first housing 210 and the second housing 220 together, thereby restricting the relative rotation and separation of the first housing 210 and the second housing 220. This allows the first chamber 212 and the second chamber 222 to be tightly enclosed to form a sealed receiving cavity, preventing the liquid inside the receiving cavity from flowing out, which facilitates the use of the cryogenic molding mold 200. When unlocking is required, the user only needs to press the snap hook 310 to squeeze the torsion spring to rotate in the opposite direction and make the snap hook 310 disengage from the slot 321 of the snap-fit ​​element 320. The operation is simple and convenient.

[0043] It should be noted that in the above embodiment, the hook 310 is rotatably mounted on the second fixed end 225 of the second housing 220, and the snap-fit ​​member 320 is disposed on the first fixed end 215 of the first housing 210. However, in other embodiments of this utility model, the hook 310 and the snap-fit ​​member 320 can also adopt other structures, such as the hook 310 being rotatably mounted on the first fixed end 215 of the first housing 210, and the snap-fit ​​member 320 being disposed on the second fixed end 225 of the second housing 220. By adopting the above technical solution, when the first housing 210 and the second housing 220 are fitted together, the hook 310 can also cooperate with the snap-fit ​​member 320 to snap together and lock the first housing 210 and the second housing 220 together.

[0044] Reference Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 In some embodiments of this utility model, the cryogenic molding mold 200 includes a hand-held part 400. A notch 410 is provided on the side wall of the first chamber 212 away from the first movable end 211, or a notch 410 is provided on the side wall of the second chamber 222 away from the second movable end 221. One end of the hand-held part 400 passes through the notch 410 and extends into the receiving cavity. The hand-held part 400 is provided with a sealing member 420 that can seal the notch 410. The sealing member 420 is detachably embedded in the notch 410. A tray member 430 is provided at one end of the hand-held part 400 located outside the receiving cavity. The tray member 430 is arranged around the outer periphery of the hand-held part 400. By adopting the above structure, when the cryogenic molding mold 200 of this embodiment is used to make ice products, the user can first extend a portion of the handle 400 into the receiving cavity, and allow the seal 420 to be detachably fitted into the notch 410. Then, the liquid to be frozen is poured into the first chamber 111 and / or the second chamber 121. Afterwards, the first shell 210 and the second shell 220 rotate relative to each other and fit together so that the first chamber 212 and the second chamber 222 surround each other to form a receiving cavity. Finally, the liquid cryogenic molding mold is placed into the freezing chamber of the freezing equipment for freezing. After the ice products are made, The user drives the first housing 210 and the second housing 220 to rotate relative to each other and separate. The user can not only hold the end of the handle 400 located outside the receiving cavity and remove the ice product from the receiving cavity, but also hold the handle 400 to eat the ice product. The operation is more convenient. The handle 400 is also provided with a tray 430. When the melted liquid on the outer surface of the ice product flows down or drips down the handle 400, the tray 430 can catch the flowing or dripping liquid and prevent the liquid from flowing or dripping onto the user's hand, so that the user's hand can be kept clean.

[0045] In some embodiments of this utility model, the first fixed end 215 has a first clearance hole 216 to avoid the handle part 400 and the tray part 430, and the second fixed end 225 has a second clearance hole 226 to avoid the handle part 400 and the tray part 430. By adopting the above structure, when the first housing 210 and the second housing 220 rotate and fit together relative to each other, the handle part 400 and the tray part 430 will not interfere with each other, ensuring that the first housing 210 and the second housing 220 can fit together normally.

[0046] Reference Figure 4 , Figure 5 , Figure 6 and Figure 12 In some embodiments of this utility model, the evaporator 130 includes two heat-conducting plates 131 and a refrigerant pipe 132. In this embodiment, both heat-conducting plates 131 are copper-based or aluminum-based plates with good thermal conductivity, and the refrigerant pipe 132 is a copper pipe with good thermal conductivity. The two heat-conducting plates 131 are arranged relatively at intervals, and the space between the two heat-conducting plates 131 forms a freezing cavity 150. That is, the two heat-conducting plates 131 are arranged relatively parallel, and a space is left between the two heat-conducting plates 131 to accommodate the freezing molding mold 200. At this time, the space between the two heat-conducting plates 131 constitutes the freezing cavity 150. One of the heat-conducting plates 131 has one or more mounting slots 133 on its outer side wall, or both heat-conducting plates 131 have one or more mounting slots 133 on their outer side walls. A refrigerant pipe 132 is arranged around the outer periphery of the two heat-conducting plates 131. The refrigerant pipe 132 has a straight pipe section 1321 and a bent pipe section 1322, with the straight pipe section 1321 fitted into the corresponding mounting slot 133. By adopting the above structure, it is convenient for the refrigerant pipe 132 to be wound circumferentially around the two heat-conducting plates 131. Furthermore, during installation, it is only necessary to correspondingly fit the straight pipe section 1321 of the refrigerant pipe 132 into the mounting slot 133 on the outer side wall of the heat-conducting plate 131. This simple and convenient operation helps reduce the assembly difficulty of the refrigerant pipe 132 and the heat-conducting plate 131, thereby facilitating the production and processing of the evaporator 130 in this embodiment and greatly reducing the production cost of the evaporator 130.

[0047] In order to enable the refrigerant pipe 132 to better conduct heat and cool the two heat-conducting plates 131, in some embodiments of this utility model, multiple mounting slots 133 are provided on the outer side walls of the two heat-conducting plates 131. The multiple mounting slots 133 of each heat-conducting plate 131 are arranged sequentially and spaced apart in the vertical direction. The refrigerant pipe 132 is wound around the outer periphery of the two heat-conducting plates 131 multiple times, so that multiple straight pipe sections 1321 of the refrigerant pipe 132 are correspondingly embedded in the multiple mounting slots 133 of each heat-conducting plate 131. By adopting the above structure, the heat conduction area between the refrigerant pipe 132 and the two heat-conducting plates 131 can be increased, thereby improving the heat conduction performance between the refrigerant pipe 132 and the two heat-conducting plates 131. Therefore, the refrigerant pipe 132 can better conduct heat and cool the two heat-conducting plates 131 and enable the interior of the freezing chamber 150 to cool down quickly.

[0048] Furthermore, the straight pipe section 1321 of the refrigerant pipe 132 is embedded inside the fitting groove 133, and the ends of the two opposite side walls of the fitting groove 133 are bent relative to each other to form a bent fitting portion 1330 that fits the outer side wall of the straight pipe section 1321. When producing the evaporator 130, the manufacturer can first embed the straight pipe section 1321 of the refrigerant pipe 132 inside the fitting groove 133, and then the manufacturer can squeeze the ends of the two opposite side walls of the fitting groove 133, so that the ends of the two side walls of the fitting groove 133 are bent relative to each other to form a bent fitting portion 1330 that fits the outer side wall of the straight pipe section 1321. By adopting the above structure, the contact area between the straight pipe section 1321 of the refrigerant pipe 132 and the inner wall of the mounting groove 133 can be further increased, thereby improving the heat exchange efficiency between the refrigerant pipe 132 and the heat-conducting plate 131, so that the refrigerant pipe 132 can absorb the heat of the heat-conducting plate 131 more efficiently and the interior of the freezing chamber 150 can be cooled down quickly.

[0049] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments of the present invention, the liquid freezing device includes a cover plate 103. The cover plate 103 is detachably installed on the outside of the outer shell 101 at a position corresponding to the opening 151. Specifically, one end of the cover plate 103 is rotatably connected to the outer shell 101. At this time, the cover plate 103 can be flipped relative to the outer shell 101, so that the other end of the cover plate 103 is away from the outer shell 101. At this time, the opening 151 is exposed. The user can pass the cryogenic molding die 200 through the opening 151 of the outer shell 101 and insert it into the freezing chamber 150. Then the user drives the cover plate 103 to flip relative to the outer shell 101, so that the other end of the cover plate 103 is attached to the outer shell 101. At this time, the cover plate 103 and the outer shell 101 work together to wrap the entire cryogenic molding die 200 inside, thereby playing a role in heat insulation. When it is necessary to remove the frozen forming mold 200, the user only needs to drive the cover plate 103 to flip relative to the outer shell 101 and make the other end of the cover plate 103 away from the outer shell 101, so that the opening 151 is exposed. At this time, the user can pull out the frozen forming mold 200 inserted into the freezing chamber 150. The operation is simple and convenient.

[0050] It should be noted that in the above embodiment, one end of the cover plate 103 is rotatably connected to the outer shell 101. However, in other embodiments of this utility model, other installation and connection structures can be used between the cover plate 103 and the outer shell 101. For example, a first permanent magnet and a second permanent magnet capable of generating a magnetic attraction force can be provided between the cover plate 103 and the outer shell 101. The first permanent magnet is disposed on the cover plate 103, and the second permanent magnet is disposed on the outer shell 101. By adopting the above structure, the cover plate 103 is fitted into the outer shell 101, and the first permanent magnet and the second permanent magnet are connected. The second permanent magnets generate a magnetic attraction force, causing the cover plate 103 to adhere to the outer shell 101. When the user needs to open the opening 151, the user only needs to apply force to the cover plate 103 and overcome the magnetic attraction force generated between the first and second permanent magnets. The user can then remove the cover plate 103 so that the user can insert the freeze-forming mold 200 into the freezing chamber 150 or pull out the freeze-forming mold 200 inside the freezing chamber 150. After the operation is completed, the user only needs to close the cover plate 103 back onto the outer shell 101. The operation is simple and convenient.

[0051] Reference Figures 1 to 12 In some embodiments of this utility model, the liquid freezing equipment is an ice block maker or a popsicle maker. That is, when the user loads water into the receiving cavity of the freezing mold 200, and then places the freezing mold 200 into the freezing chamber 150 to freeze it into ice, the liquid freezing equipment is an ice block maker. Alternatively, when the user loads the liquid material for making popsicles into the receiving cavity of the freezing mold 200, and then places the freezing mold 200 into the freezing chamber 150 to freeze it into popsicles, the liquid freezing equipment is a popsicle maker. The specific method can be determined according to actual needs.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
