However, most medical refrigerators are powered by an external power source, meaning they are connected to a power outlet or power strip via a power cord. Therefore, in the event of a power outage or interruption, the medical refrigerator cannot maintain its internal temperature and loses its refrigeration effect, potentially causing medicines to lose their medicinal properties and resulting in a poor user experience.

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0045] This application provides a device with a refrigeration function, which can be a vehicle refrigerator, a small household refrigerator, or a refrigerator box, such as a medical refrigerator box or a home medical box.

[0046] Specifically, such as Figures 1 to 8 As shown, the refrigeration equipment includes a housing 1, a heat pump system 2, a cold storage box 3, a fan assembly 4, and a battery 5.

[0047] The enclosure 1 has a separate refrigeration chamber 11a and a refrigeration chamber 11b. A heat pump system 2 is located inside the enclosure 1 and is capable of refrigerating the refrigeration chamber 11a. A cold storage tank 3 is located inside the refrigeration chamber 11a. The cold storage tank 3 has a cavity for holding cold storage refrigerant and a refrigeration air duct 31 formed by the outer wall of the cavity. The refrigeration air duct 31 has an air inlet 31b and an air outlet 31a, and both the air inlet 31b and the air outlet 31a are connected to the refrigeration chamber 11b. A fan assembly 4 is capable of generating circulating air through the refrigeration air duct 31. A battery 5 is located inside the enclosure 1 and is capable of supplying power to at least the fan assembly 4.

[0048] Understandably, this refrigeration device uses a heat pump system 2 to cool the refrigeration chamber 11a and, through the cooperation of a cold storage box 3 and a fan assembly 4, delivers cold energy to the refrigeration chamber 11b, enabling the refrigeration chamber 11b to achieve its refrigeration function. Furthermore, the cold storage box 3 can store cold energy, so that in the event of a power outage or power failure, the fan assembly 4, powered by a battery 5, delivers the cold energy stored in the cold storage box 3 to the refrigeration chamber 11b through circulating air passing through the refrigeration duct 31, thereby extending the duration of the refrigeration function of the refrigeration chamber 11b and improving the user experience.

[0049] In addition, the cold storage box contains a cold storage agent, eliminating the need for heat exchange between the flowing cold storage agent and the air in the refrigeration duct 31, thus simplifying the structure of the cold storage box.

[0050] It should be noted that the above-mentioned cold storage box can be integrally formed or it can be set up in parts. For example, the cold storage box is assembled from at least two parts, and the above-mentioned refrigeration air duct 31 is formed between the at least two parts.

[0051] In other words, this refrigeration device, compared to existing refrigerators or devices with both freezer and refrigerator compartments, eliminates the evaporator in the original refrigerator compartment. Instead, it utilizes the freezer compartment to provide cooling for the refrigerator compartment and stores the cooling capacity through a cold storage tank 3, so that it can continuously supply cooling capacity to the refrigerator compartment 11b for a certain period of time during power outages or power failures. Alternatively, refrigerators or devices with both freezer and refrigerator compartments can be modified by removing the evaporator in the refrigerator compartment, adding a fan assembly, and installing a water storage tank in the freezer compartment.

[0052] The aforementioned battery 5 may supply power only to the fan assembly 4, or it may be configured to supply power to both the heat pump system 2 and the fan assembly 4.

[0053] It should be noted that the refrigeration device has a power interface or power cord for connecting to an external power source. For example, in the event of a power outage, both the fan assembly and the heat pump system are powered by an external power source, which can also charge the battery 5. In the event of a power outage or power failure, the fan assembly 4 is powered by the battery 5, while the heat pump system 2 does not operate, utilizing the cold storage capacity stored in the cold storage box 3 to maintain the refrigeration function of the refrigeration chamber 11b. Alternatively, the refrigeration device can operate for Nh under external power supply and then operate for Mh after a power outage, where N > 0 and M > 0. After the power failure, the circulating air formed by the fan assembly 4 through the refrigeration duct 31 delivers cold air to the refrigeration chamber 11b.

[0054] The power interface described above can be a DC input power interface, which can power the entire device via an adapter. The adapter can be an AC to DC adapter, a diesel engine to DC adapter, etc.

[0055] In some embodiments, refer to Figure 2 The refrigeration equipment also includes a photovoltaic module 7, which can supply power to the battery 5, the fan assembly 4, and the heat pump system 2.

[0056] Understandably, by installing photovoltaic modules 7, the refrigeration equipment can utilize solar energy to power the battery 5, fan assembly 4, and heat pump system 2. This allows the refrigeration equipment to maintain its refrigeration function even during power outages. Of course, the refrigeration equipment can also use photovoltaic modules 7 as its primary power source. For example, if the photovoltaic panels of photovoltaic module 7 are located outdoors, the electricity generated by photovoltaic module 7 can power the battery 5, fan assembly 4, and heat pump system 2. When photovoltaic module 7 cannot utilize solar energy, the battery 5 can power the fan assembly 4 to continue providing cooling to the refrigeration chamber 11b.

[0057] The aforementioned photovoltaic module 7 includes a photovoltaic panel, which can be installed on the housing 1, or the photovoltaic panel can form the top or side panel of the housing 1. In other words, the photovoltaic panel is integrated into the housing 1 as part of the structure of the housing 1. In addition, the photovoltaic panel can also be connected to the main controller 8 of the refrigeration equipment via a cable. In this case, the photovoltaic panel can be installed outdoors to better utilize solar energy to power the refrigeration equipment.

[0058] Furthermore, the refrigeration device also includes a main controller 8, and the battery 5, fan assembly 4, photovoltaic module 7 and heat pump system 2 are all connected to the main controller 8.

[0059] The main controller 8 controls the battery 5 and photovoltaic module 7 to perform corresponding functions. For example, when the photovoltaic module 7 can generate electricity using solar energy, the main controller 8 can control the photovoltaic module 7 to charge the battery 5, supply power to the heat pump system 2, and supply power to the fan assembly 4. In other words, at this time, the photovoltaic module 7 is mainly used to ensure the power supply of the equipment with refrigeration function. When the photovoltaic module 7 cannot generate electricity using solar energy, such as on cloudy days or in rainy or snowy weather, the main controller 8 controls the battery 5 to supply power to the fan assembly 4, using the cold storage box 3 to provide cooling for the refrigeration chamber 11b.

[0060] Reference Figure 3 The device with refrigeration function also includes a temperature detector 9, which is located at the air outlet 31a or inside the refrigeration chamber 11b.

[0061] The temperature detector 9 is connected to the main controller 8, and the main controller 8 can control the start and stop of the heat pump system 2 by the temperature detected by the temperature detector 9.

[0062] In the first scenario, when temperature detector 9 is located at air outlet 31a, when the temperature at air outlet 31a reaches the first set temperature, main controller 8 controls heat pump system 2 to stop working, that is, controls the compressor of heat pump system 2 to stop working. During this process, main controller 8 controls fan assembly 4 to continue working. When the temperature at air outlet 31a reaches the second set temperature, main controller 8 controls fan assembly 4 to stop working to prevent over-condensation.

[0063] The first set temperature is lower than the phase change temperature of the refrigerant, and the second set temperature is lower than the first set temperature. Both the first and second set temperatures can be set based on the phase change temperature of the refrigerant. For example, if the refrigerant is water, the first set temperature is 0℃ to -1℃, and the second set temperature is -1℃ to -2℃.

[0064] In the second scenario, when temperature detector 9 is located within the refrigeration chamber 11b, and it detects that the temperature has reached the third set temperature, the main controller 8 stops the heat pump system 2. During this process, the main controller 8 also controls the fan assembly 4 to operate. When temperature detector 9 detects that the temperature has reached the fourth set temperature, the main controller 8 stops the fan assembly 4 to prevent over-condensation. The fourth set temperature is lower than the third set temperature; for example, the third set temperature is 2℃-3℃, and the fourth set temperature is 1℃-2℃.

[0065] In addition, when the temperature detected by the temperature detector 9 exceeds the third set temperature, the main controller 8 controls the heat pump system 2 to start, and when the temperature detected by the temperature detector 9 is higher than the fourth set temperature, the main controller 8 controls the fan assembly 4 to work.

[0066] In the third scenario, temperature detector 9 is installed inside the refrigeration chamber 11b. When the temperature detected by temperature detector 9 is lower than the fifth set temperature, the main controller 8 controls the fan assembly 4 to start and stop at preset intervals, such as starting for 5 minutes and stopping for 5 minutes. When the temperature detected by temperature detector 9 is higher than the fifth set temperature, the main controller 8 controls the fan assembly 4 to remain on.

[0067] Of course, the aforementioned refrigeration equipment may not have a temperature sensor. In this case, ensuring that the refrigerant in the cold storage box 3 maximizes its cold storage capacity while the heat pump system 2 is operating normally, will allow the main controller 8 to control the fan assembly 4 to continue operating for a set time during power outages or power failures, thus ensuring that the temperature of the refrigeration chamber 11b remains within the allowable range. For example, if the refrigerant is water, then at the initial stage of a power outage or power failure, the water in the cold storage box 3 will have a 100% freezing rate, and the surface temperature of the cold storage box 3 will be approximately 0°C.

[0068] In some embodiments, refer to Figure 4 and Figure 5 The refrigeration duct 31 of the cold storage box 3 includes at least two duct segments that both extend along a first direction, and the at least two duct segments are arranged sequentially in a second direction. The length of the partition between two adjacent duct segments in the first direction is less than the length of either of the two duct segments. The air outlet 31a and the air inlet 31b are located on the same side of the cold storage box 3 in the first direction, and the first direction and the second direction intersect.

[0069] Understandably, two adjacent sections of the cooling air duct 31 are connected to form a U-shaped air duct, which can increase the heat exchange area and prolong the residence time of the air entering from the air inlet 31b in the cooling air duct 31, thereby improving the heat exchange efficiency.

[0070] It should be noted that the cooling air duct 31 may be provided with at least one air inlet 31b and at least one air outlet 31a, and one air outlet 31a may correspond to one air inlet 31b, or at least two air inlets 31b may share one air outlet 31a.

[0071] For example, refer to Figure 5 The cooling air duct 31 includes three air duct sections, which are arranged sequentially in the second direction. One end of the middle air duct section forms an air outlet 31a, while one end of the other two air duct sections forms an air inlet 31b. At this time, the cooling air duct 31 has two air inlets 31b and one air outlet 31a. The air entering through each air inlet 31b flows along the U-shaped air duct and exchanges heat with the refrigerant in the cold storage box 3.

[0072] The three air duct segments are of the same length in the first direction, while the length of the partition between two adjacent air duct segments in the first direction is two-thirds to three-quarters of the length of the air duct segment.

[0073] For example, in one specific implementation, the aforementioned air duct segment can extend through both sides of the cold storage box 3 in the first direction. That is, both ends of each air duct segment are open in the first direction. When the cold storage box 3 is placed in the refrigeration chamber 11a, the same side wall of the refrigeration chamber 11a blocks one of the openings of each air duct segment. In this way, the partition between two adjacent air duct segments forms a U-shaped air duct.

[0074] Alternatively, in another specific implementation, the aforementioned air duct segment has an opening at one end in the first direction, such that the opening of each air duct segment forms an air inlet or an air outlet, in which case the air inlet and air outlet of the cooling air duct are located on the same side of the housing in the first direction.

[0075] Furthermore, the aforementioned cold storage box can also be equipped with fins in the refrigeration air duct or the cold storage water tank itself can have protrusions located in the refrigeration air duct, thereby increasing the heat exchange area and improving the heat exchange efficiency.

[0076] In some embodiments, refer to Figure 5 and Figure 6 The enclosure 1 includes an enclosure body 11 and a first door 12. The enclosure body 11 has a refrigeration chamber 11a and a refrigerator chamber 11b. The first door 12 is rotatably connected to the enclosure body 11 and can close or open the refrigeration chamber 11a. The first door 12 has transition channels 12a corresponding to the air inlet 31b and the air outlet 31a, and the fan assembly 4 is located at the transition channel 12a that connects to the air outlet 31a.

[0077] Understandably, the first door 12 can separate the refrigeration chamber 11a and the refrigerator chamber 11b, preventing the cold air from the refrigeration chamber 11a from directly entering the refrigerator chamber 11b, thereby allowing the temperature inside the refrigerator chamber 11b to be controlled by controlling the airflow of the circulating air through the fan assembly 4.

[0078] It should be noted that when the first door 12 is opened, the refrigeration chamber 11a and the refrigeration chamber 11b are in a connected state within the main body 11, meaning that the cold air in the refrigeration chamber 11a will directly diffuse into the refrigeration chamber 11b. However, by setting the first door 12, the cold storage box 3 is directly placed inside the refrigeration chamber 11a. When the first door 12 is closed, the refrigeration chamber 11a can only connect to the refrigeration chamber 11b through the refrigeration air duct 31 of the cold storage box 3 and the transition channel 12a on the first door 12. At this time, the first door 12 is sealed around its perimeter.

[0079] The cold storage box 3 can be set to be the same size as the refrigeration chamber 11a, in which case the cold storage box 3 just fills the refrigeration chamber 11a, and the refrigeration chamber 11a only provides cooling capacity and does not serve as storage space. Of course, the cold storage box 3 can also be set to be smaller than the refrigeration chamber 11a, in which case the remaining space of the refrigeration chamber 11a can still be used as storage space.

[0080] Furthermore, the device housing 1 also includes a second door (not shown in the figure) rotatably connected to the housing body 11. The housing body 11 has an opening, and the second door can open or close the opening of the housing body 11. Understandably, at this time, the housing body 11 has a refrigeration chamber 11a and a refrigerator chamber 11b. The first door 12 can close the refrigeration chamber 11a, while the second door can simultaneously close both the refrigerator chamber 11b and the refrigeration chamber 11a. When the cold storage box 3 occupies the entire space of the refrigeration chamber 11a, the refrigeration chamber 11a is not used as a storage space, and the first door 12 remains normally closed. The second door is mainly used to open and close the refrigerator chamber 11b.

[0081] For example, in one specific implementation, the refrigeration duct 31 has an air outlet 31a and at least one air inlet 31b, and the air inlet 31b and the air outlet 31a are located on the same side of the cold storage box 3. The fan assembly 4 is disposed at the transition channel 12a corresponding to the air outlet 31a. The fan assembly 4 performs a suction operation, so that the air in the refrigeration chamber 11b enters the refrigeration duct 31 through the air inlet, and after exchanging heat with the refrigerant in the cold storage box 3, it is blown out through the air outlet 31a.

[0082] Optionally, in other embodiments, the equipment housing may have a partition separating the refrigeration chamber and the refrigerator chamber. The partition has transition channels corresponding to both the air outlet and the air inlet, which also allows for communication between the refrigeration duct and the refrigerator chamber. The air outlet directly blows the cold air from the refrigeration duct into the refrigerator chamber. In this case, the equipment housing may include a housing with a refrigeration chamber and a refrigerator chamber, and a first door and a second door rotatably mounted on the housing. The first door can open or close the refrigeration chamber, and the second door can open or close the refrigerator chamber.

[0083] Alternatively, the first door can only have a transition channel connecting the air outlet, while the box body has an air exchange channel connecting the refrigeration chamber and the cold storage chamber, and the air exchange channel has an air inlet. This can also achieve the formation of circulating air. In this case, the air inlet and air outlet of the refrigeration air duct can be set on different sides of the cold storage box. For example, the air inlet of the refrigeration air duct is located on the rear side of the cold storage box, while the air outlet is located on the front side of the cold storage box. The front and rear sides of the cold storage box are distinguished according to the front and rear direction of the equipment with refrigeration function.

[0084] Reference Figure 7 and Figure 8 The aforementioned refrigeration device may also include a guide member 6 connected to the first door 12. The guide member 6 has an air guide channel 6a, one end of which is connected to the transition channel 12a, and the other end extends into the refrigeration chamber 11b.

[0085] Understandably, by setting the guide component 6, the air duct 6a can directly guide the cold air discharged from the air outlet 31a into the refrigeration chamber 11b, which is conducive to the rapid entry of cold air into the refrigeration chamber 11b, making the temperature of the refrigeration chamber 11b more uniform.

[0086] For example, refer to Figure 7The aforementioned refrigeration chamber 11a is located above the refrigerator chamber 11b. In this case, the air guide channel 6a extends from top to bottom, thereby adjusting the direction of the cold air discharged from the transition channel 12a from blowing towards the front of the first door 12 to blowing towards the bottom of the first door 12, that is, directly into the refrigerator chamber 11b, ensuring the uniformity of temperature within the refrigerator chamber 11b. Alternatively, the refrigeration chamber can also be located below the refrigerator chamber, in which case the guide channel extends from bottom to top. Or, the refrigeration chamber can also be located on one side of the refrigerator chamber in the horizontal direction, in which case the air guide channel extends horizontally to deliver cold air into the refrigerator chamber.
