[0030] Refrigeration systems (e.g., refrigerators and coolers) are commonly used to store products (e.g., beverages and snacks) in a temperature-controlled environment. These refrigeration systems can be used in a variety of locations, such as grocery stores, convenience stores, shopping malls, sports stadiums or concert venues, gas stations, offices, and movie theaters. These refrigeration systems typically have doors that allow easy access to the products stored within the system. Although these systems provide convenience, they can be challenging to maintain freezing temperatures due to the frequent opening of the doors, and they include a number of other disadvantages.

[0031] Refrigeration systems typically have a single compartment that is maintained at or near a target temperature to generally maintain a single temperature throughout the system, despite the fact that various products may have different temperature requirements. Typically, this means that the temperature of the entire system must be maintained at or below the appropriate temperature for the product with the lowest temperature requirement. Existing systems typically do not allow a single system to maintain different temperatures for different zones of the system.

[0032] Some refrigeration systems have a lockout feature that will prevent access to the system if, for example, the refrigeration unit fails or the temperature exceeds the maximum temperature of the product stored within the system. But the lockout typically locks the door of the refrigeration system, preventing access to the entire unit, even if some of the products are not perishable or temperature sensitive. Often, the system must remain locked until the system is serviced, which may prevent access for hours or even days.

[0033] To accommodate these shortcomings, multiple refrigeration systems are often used to store different products with different temperature requirements. For example, typically, a dedicated system is required for items that must be pre-cooled (e.g., perishable and temperature-sensitive products), and another dedicated system is required for shelf-stable products (e.g., non-perishable products).

[0034] Embodiments described herein overcome these and other challenges by providing modular units for refrigeration systems and other benefits, which allow the temperature of each unit to be controlled independently of other units or the rest of the storage compartment in the refrigeration system. The temperature of each modular unit can be controlled independently of other modular units and independently of the entire storage compartment of the refrigeration system. The modular units disclosed herein can be locked in response to, for example, temperature changes. This only blocks access to the locked modular units and allows consumers to access the rest of the refrigeration system. The modular units allow convenient access to the product while minimizing heat transfer to the freezing environment when the door of the refrigeration system is opened. The modular units disclosed herein can also be integrated into existing refrigeration systems and can be rearranged within the refrigeration system. This allows flexible and more efficient storage of products.

[0035] Figure 1 A refrigerator system (eg, system 10 ) is shown according to some embodiments. Figure 2 A diagram of system 10 is shown. In some embodiments, system 10 includes cabinet 100, electronic system 200, refrigeration system 300, storage compartment 102, and one or more modular storage units 400 disposed within storage compartment 102. In some embodiments, system 100 includes storage compartment 102, sidewalls 105, front side 110, back side 115, and top 120.

[0036] In some embodiments, the storage compartment 102 is partially defined by the sidewalls 105, the front side 110, the back side 115, and the top 120. In some embodiments, the front side includes a door 112. In some embodiments, the door 112 includes a frame 113. In some embodiments, the door 112 includes a transparent portion 114. The transparent portion 114 can be made of various materials such as glass or acrylic. In some embodiments, the transparent portion 114 is glass. In some embodiments, the transparent portion 114 is insulating glass. In some embodiments, the storage compartment 102 is visible through the transparent portion 114. The storage compartment 102 may include one or more shelves 150 disposed in the storage compartment 102. In some embodiments, the storage compartment 102 includes 1 or more (e.g., 2 or more, 3 or more, 4 or more, or 5 or more) shelves 150.

[0037] like Figure 1 As shown, the system 10 can include modular storage units 400. In some embodiments, the system 10 includes 1 or more (e.g., 2 or more, 3 or more, 4 or more, or 5 or more) modular storage units 400. Each modular storage unit 400 can be movable within the storage compartment 102. In some embodiments, each modular storage unit can be removably coupled to the shelf 150. Figures 3 to 5A An exemplary configuration of modular storage units 400 is shown. Each modular storage unit 400 can be configured to use the refrigeration system 300 of the system 10 to redirect cold air into the modular storage unit 400. In some embodiments, as described in more detail below, the modular storage unit 400 can continuously redirect cold air from the refrigeration system 300 to adjust the temperature of the modular storage unit 400 separately from the rest of the storage compartment 102. In some embodiments, as described in more detail below, the modular storage unit 400 can selectively redirect cold air from the refrigeration system 300 to adjust the temperature of the modular storage unit 400 separately from the rest of the storage compartment 102.

[0038] Figure 3 An exemplary modular storage unit 400 is illustrated. In some embodiments, the modular storage unit includes a door 405, a side wall 410, a rear wall 415, and a bottom 420. In some embodiments, the modular storage unit 400 includes an interior volume 401 at least partially defined by the door 405, the side wall 410, the rear wall 415, and the bottom 420. In some embodiments, the rear wall 415 includes an opening 416 disposed in the rear 415. In some embodiments, the opening 416 is an air inlet for receiving cold air from the refrigeration system 300. In some embodiments, the bottom 420 includes a vent 421 that allows air to flow upward through the bottom 420 and into the interior volume 401.

[0039] The modular storage unit 400 may include a door 405 that moves from a closed position to an open position. The door 405 may be hinged, rollable, or slidable. Figure 3 and Figure 4 As shown, the modular storage unit 400 may include a door 405 hingedly coupled to the bottom 420 by a hinge 406. After opening the door 112 of the cabinet 100, the user can access the products stored in the modular storage unit 400 by pulling the door 405 from the top to rotate the door 405 around the hinge 406. In some embodiments, the door 405 can be slidably coupled to the bottom 420, for example, along a track defined in the bottom 420. In some embodiments, the door 405 is rollable (e.g., a rollable curtain or a spring-loaded roller). In some embodiments, the door 405 is made of a transparent material (e.g., glass, acrylic, polycarbonate, polyethylene terephthalate (PET), or polyvinyl chloride (PVC)) so that the products stored in the modular storage unit 400 are visible before the door 405 is opened.

[0040] like Figure 3 and Figure 4As shown, the door 405 may include one or more locks 435 configured to lock the door 405. In some embodiments, the lock 435 is an electromagnetic lock. In some embodiments, the lock 435 is configured to lock and unlock based on specific conditions (e.g., when the electronic device 200 detects a payment source or the temperature within the modular storage unit 400 exceeds a predetermined temperature). In some embodiments, the modular storage unit 400 includes a temperature sensor (e.g., temperature sensor 220) that detects the temperature within the modular storage unit 400. In some embodiments, if the temperature sensor 220 detects that the temperature within the modular storage unit 400 is at or above a predetermined temperature (e.g., 5°C, 3°C, or 1°C), the control unit 203 may activate the lock 435 to prevent access to the modular storage unit 400. Since warmer air may be able to enter the modular unit 400 when the door 405 is opened, this can minimize the warmer air entering the modular unit 400. In some embodiments, the lock 435 is automatically locked based on the detection of the temperature sensor 220. In some embodiments, the lock 435 will remain locked before the temperature sensor 220 detects that the temperature in the modular storage unit 400 is lower than the predetermined temperature. In some embodiments, the lock 435 is unlocked only when the temperature in the modular storage unit 400 is lower than the predetermined temperature. If some temperature-sensitive products are stored for an extended period of time at a temperature higher than 5°C, they will deteriorate. Therefore, in some embodiments, if the temperature sensor 220 detects that the temperature in the modular storage unit 400 is higher than the predetermined temperature for a predetermined time (e.g., 30 minutes, 60 minutes, or 90 minutes), the lock 435 will remain locked before the modular storage unit 400 is replenished with new products. In some embodiments, the predetermined temperature is about 40°F to about 50°F (e.g., about 41°F to about 45°F). In some embodiments, the predetermined time is about 1 minute to about 45 minutes (e.g., about 5 minutes to about 30 minutes or about 10 minutes to about 20 minutes). In some embodiments, the predetermined temperature is 45°F and the predetermined time is 5 minutes. In some embodiments, the predetermined temperature is 41°F and the predetermined time is 30 minutes.

[0041] The lock 435 can be a fail-safe lock or a fail-safe lock. In some embodiments, the lock 435 is a fail-safe lock that remains locked in the event that the system 100 loses power. This can be used, for example, to prevent a user from accessing a temperature sensitive product in the event that the system 100 loses power. In some embodiments, the lock 435 is a fail-safe lock that is unlocked in the event that the system 100 loses power. This can be used, for example, to allow access to a shelf-stable product in the event that the system 100 loses power.

[0042] Modular storage unit 400 may have one or more indicator lights (e.g., indicator light 430) that show the status of modular storage unit 400. In some embodiments, indicator light 430 is a light that illuminates based on whether lock 435 is locked. For example, in some embodiments, indicator light 430 is a light that illuminates when lock 435 is locked. In some embodiments, a modular unit includes two indicator lights 430, such as Figure 3 and Figure 4 In some embodiments, one indicator light 430 illuminates when the lock 435 is locked, and another indicator light 430 illuminates when the lock 435 is unlocked. In some embodiments, the indicator light 430 illuminates only when the lock 435 is locked.

[0043] The modular storage unit 400 may have various arrangements within the interior volume 401. For example, Figure 3 An arrangement having a series of partitions 450 is shown, and Figure 4 An arrangement is shown having a U-shaped insert contacting sidewalls 410 and a bottom 420. Each of these is exemplary and is discussed in more detail below.

[0044] like Figure 3 As shown, modular storage unit 400 may have one or more insulating panels (e.g., dividers 450). In some embodiments, each divider 450 extends between door 405 and rear wall 415 in a first direction so that sides 451 of divider 450 face each other. In some embodiments, dividers 450 are parallel to each other. In some embodiments, divider 450 is an insulating panel. In some embodiments, divider 450 includes a phase change material (e.g., paraffin, non-paraffin organic matter, hydrated salt, water or gel) disposed in divider 450. In some embodiments, phase change material is one of paraffin, non-paraffin organic matter or hydrated salt. Divider 450 may be able to move between side walls 410 in a second direction to adjust the space between each divider. The spacing between each divider 450 may be able to vary. For example, some dividers may be spaced apart enough to accommodate a jar, while other dividers 150 in the same modular storage unit 400 may be spaced apart to accommodate snacks wider than the jar. This allows the modular storage unit 400 to accommodate products of various sizes and allows for easy reconfiguration if a replacement product has a different size or shape. In some embodiments, the first direction and the second direction are perpendicular. In some embodiments, the divider 450 includes an inlet 452 that provides an entry point for adding phase change material to the divider 450.

[0045] Figure 4 A modular storage unit 400 is illustrated with an insulating liner (e.g., liner 455). In some embodiments, Figure 4The modular storage unit 400 shown includes Figure 3 The modular storage unit 400 shown has the same features, but with a liner 455. In some embodiments, the liner 455 may replace or be combined with Figure 3 In some embodiments, the liner 455 includes a bottom wall 456 and side walls 457. In some embodiments, the bottom wall 456 covers at least a portion of the bottom 420. In some embodiments, each side wall 457 covers at least a portion of the side wall 410. In some embodiments, the liner 455 includes a phase change material (e.g., water or gel) disposed within the liner 455.

[0046] Figure 5A A modular storage unit 400 is illustrated according to some embodiments. Figure 5B The example taken along line 5B-5B Figure 5A 400. In some embodiments, the modular storage unit 400 may include a channel 460 extending from the rear wall 415 to the front side near the door 405. Figure 5B As shown, the channel 460 may include an inlet near the rear wall 415 and an outlet near the front side of the door 405, and the cold air may flow through the interior volume 461 (e.g., in the direction of arrow 462). In some embodiments, the cold air exits the channel 460 and forms a cold air curtain 463 at the front door 405. In some embodiments, the cold air curtain 463 provides insulation in front of the door 405. In some embodiments, the modular storage unit 400 may include a fan 465 that draws cold air from the refrigeration system 300 into the channel 460. In some embodiments, as shown in FIG. Figure 5A and Figure 5B The illustrated duct 460 and fan 465 may be used in conjunction with the divider 450 or the liner 455 or both. Figure 5B A product 500 disposed within the interior volume 401 is illustrated.

[0047] FIG. 6A to FIG. 9 B illustrates various refrigeration systems 300 that may be used in system 10 according to some embodiments. It should be understood that the modular storage units 400 described herein (e.g., Figures 3 to 5B Any modular storage unit shown in FIG. 6A to FIG. 9 B. In addition, it should be understood that Figures 3 to 5BThe modular storage unit 400 shown may be interchangeable with any other modular storage unit 400. In some embodiments, the system 10 may include 1 or more (e.g., 2 or more, 3 or more, 4 or more, or 5 or more) modular storage units within the storage compartment 102. In some embodiments, the system 10 may include 1 to 4 modular storage units 400. FIG. 6A to FIG. 9 The arrows shown at B illustrate air flow within the system 10 , with solid arrows illustrating a generally downward flow of cooler air and dashed arrows illustrating a generally upward flow of warmer air.

[0048] In some embodiments, the system 10 includes a flow path 430 through which cool air can flow downwardly through the storage compartment 402, such as FIG. 6A to FIG. 9 exemplified in B.

[0049] FIG. 6A to FIG. 6B A damper system is illustrated that can selectively direct cool air into the modular storage unit 400 (e.g., through the opening 416 or the channel 460). In some embodiments, the damper system includes a damper that can be in a first position ( Fig. 6A shown) and the second position ( Figure 6B ) between the first and second positions. In some embodiments, when the damper 132 is in the first position, cool air flowing through the flow path 130 is redirected into the modular storage unit 400. In some embodiments, when the damper 132 is in the second position, cool air flows freely through the flow path 130. In some embodiments, the system 10 includes one damper for each modular storage unit 400. In some embodiments, the control unit 203 actuates the damper 132 between the first position and the second position based on the temperature in the modular storage unit 400 as determined by the temperature sensor 220. For example, in some embodiments, when the temperature sensor 220 detects that the temperature within the modular storage unit 400 is at or above a predetermined temperature (e.g., 5°C, 3°C, or 1°C), the control unit 203 may move the damper 132 to the first position ( Fig. 6A ) to guide the cold air into the modular storage unit 400. For example, in some embodiments, when the temperature sensor 220 detects that the temperature inside the modular storage unit 400 is at or below a predetermined temperature (e.g., 5°C, 3°C, or 1°C), the control unit 203 may move the damper 132 to the second position ( Fig. 6A ), so that cool air flows normally within the system 10. In some embodiments, the damper 132 can be used with any modular storage unit 400 disclosed herein.

[0050] Figure 7 Illustrated when Figure 5A and Figure 5B The air flow within the system 10 when used with the modular storage unit 400 illustrated in FIG. Figure 7 As illustrated in FIG. 4 , cold air may preferentially enter the modular storage unit 400, flow through the channel 460, and form the air curtain 463. Figure 7 As illustrated in , some of the cool air flows into the modular storage unit 400 and some of the cool air flows through the remainder of the storage compartment 102 .

[0051] In some embodiments, such as Figure 8 As shown, the system 10 may include a plate 140 disposed proximate to the rear wall 115. In some embodiments, the plate 140 may extend vertically within the storage compartment 102 and may be spaced apart from the rear wall 115 to form the flow path 130. In some embodiments, the plate 140 extends the entire width of the storage compartment 102 (e.g., between the side walls 105). In some embodiments, when the plate 140 is used, all of the cold air flows from the top of the storage compartment 102 through the flow path 130 to the bottom of the storage compartment 102. In some embodiments, the plate 140 includes a phase change material (e.g., water or gel) disposed within the plate 140.

[0052] In some embodiments, such as Fig. 9 As illustrated in , the modular storage unit 400 may include a micro cold storage unit (e.g., cold storage unit 470) disposed within the modular storage unit 400. In some embodiments, such as Fig. 9 As shown, the system 10 may include multiple modular storage units 400 with different designs (e.g., one or more modular storage units have a refrigeration unit 470 and one or more modular storage units do not have a refrigeration unit 470). The system 10 may include fans 305 and 315. In some embodiments, the refrigeration unit 470 may control the temperature within the modular storage unit 400, and the refrigeration system 300 may control the temperature in the rest of the storage compartment 102.

[0053] Fig.10 A diagram of an electronic system 200 according to some embodiments is illustrated. In some embodiments, the electronic system 200 includes a control unit 203, a user interface 204, a payment processing unit 206, an audio unit 210, sensors (e.g., contactless payment sensor 211, biometric sensor 212, proximity sensor 218, temperature sensor 220, product sensor 226), a scanner 216, a lock 224, a camera 228, and a storage compartment light 230.

[0054] In some embodiments, control unit 203 coordinates the operation of system 10, such as Fig.10In some embodiments, a single control unit 203 may control the operation of all components of the mobile vending system 100. In some embodiments, two or more control units 203 may be used, and each control unit may be used to control a different operation or component of the system 10. For example, a first control unit may control the user interface 204 and the payment processing unit 206, while a second control unit may control the operation of, for example, a lock 224, a product sensor 226, a camera 228, and a storage compartment light 230. Although it should be understood that multiple control units 203 may be used, for convenience, the description herein primarily relates to an embodiment having a single control unit 203.

[0055] In some embodiments, such as Figure 1 As shown, the system 10 includes a user interface 204. In some embodiments, the user interface 204 is controlled by the control unit 203. In some embodiments, the electronic system 200 includes a housing 250. In some embodiments, the user interface 204 can be disposed on the housing 250. In some embodiments, as Fig.10 As shown, user interface 204 is a display. In some embodiments, user interface 204 can display instructions for operating system 10, and can also display product information to consumers during product automatic vending operations. In some embodiments, user interface 204 includes a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, and other types of displays. In some embodiments, user interface 204 receives user input. In some embodiments, user interface 204 includes a touch screen display so that consumers can touch a portion of the display to enter user input.

[0056] In some embodiments, the electronic system 200 may include a payment processing unit 206 for detecting the presence of a payment source, receiving payment from a consumer, processing the payment, and authorizing the purchase of a product. In some embodiments, the payment processing unit 206 is disposed on the housing 250. In some embodiments, the payment processing unit 206 includes at least one of the following: a magnetic stripe reader 207 for reading credit cards, debit cards, ATM cards, etc.; a chip reader for reading credit cards, debit cards, and other payment cards with electronic chips (i.e., chip cards); a contactless payment sensor (e.g., a near field communication (NFC) reader) for contactless payment. The payment processing unit 206 may also be configured to receive mobile payments, such as payments made using Apple Pay or Google Pay, and may include an RFID sensor configured to read or detect an RFID tag or a QR code reader configured to scan a QR code or barcode displayed on a printed membership card, shopping bag, bottle, or the like, or a QR code displayed on a mobile device, such as a QR code displayed on a software application (or "app") on the mobile device. In addition, the payment processing unit 206 may be configured to receive a remote payment or an indication that the consumer has made a payment, such as a payment made on a smartphone or smartphone application, and the indication of the remote payment is transmitted to the system 10 to allow the consumer to purchase the product without having to enter the payment at the system 10.

[0057] In some embodiments, the payment processing unit 206 can be used to detect authorized users. In some embodiments, the authorized user can be determined by entering an identification of the user, such as by entering the name of the user (wherein the name of the user is stored in a database), scanning an identification such as a driver's license or passport, or by entering an identification code. In addition, the electronic system 200 may include a biometric sensor that is used to determine the identity of the consumer and, therefore, the presence of the authorized user. The identity of the consumer can be bound to a payment source so that after the consumer is identified, the payment source of the consumer can be automatically accessed to purchase the product. In some embodiments, the biometric sensor can be configured to identify an individual based on fingerprints, palm prints, retinas, irises, faces or facial features, etc.

[0058] In some embodiments, the electronic system 200 may include an audio unit 210. In some embodiments, the audio unit 210 may be configured to emit or generate an audible alarm or tone. In some embodiments, the audio unit 210 may be arranged on or in the housing 250, or may be located outside the housing 250, such as on the upper part 101 or lower part 102 of the mobile vending system 100. In some embodiments, the audio unit 210 may be wired or wirelessly communicated with the system 10.

In some embodiments, the audio unit 210 may be configured to play a greeting or welcome to the consumer after detecting the consumer or after receiving the payment source. In addition, in some embodiments, the audio unit 210 may play a message to thank the consumer after completing the purchase. In some embodiments, the audio unit 210 may also be configured to generate an alarm when the product is taken out from the product storage compartment of the system 10 or returned to the product storage compartment, as discussed in further detail below.

[0059] In some embodiments, the system 10 includes a proximity sensor 218 configured to detect when a consumer is within a predetermined distance of the system 10. In some embodiments, when a consumer is near the system 10, as determined by the proximity sensor 218, the system 10 may change from a first state to a second state. In some embodiments, the first state is an inactive state, wherein the user interface 204 is turned off or in a power saving mode, and the storage compartment light 230 is turned off. In some embodiments, the second state is an active state, wherein the user interface 204 is turned on and ready to receive user input, and the storage compartment light is turned on. In some embodiments, when a consumer completes a purchase using the mobile vending system 100, the user interface 204 may change from the second state to the first state.

[0060] In some embodiments, the system 10 includes a temperature sensor 220. In some embodiments, the system 10 includes one or more temperature sensors 220 configured to detect a temperature within the system 10 (e.g., within the storage compartment 102 or within the modular storage unit 400).

For example, when a product is taken out of or placed in a storage compartment from a storage compartment 102, an optical sensor may capture a video of the product as the product passes through it, and the product in the captured video may be compared to an image library (such as an edge or cloud-based image library). Alternatively, an optical sensor may capture images of products in a storage compartment before and after a consumer purchases the product to determine which products have been taken out. However, as will be readily appreciated by those of ordinary skill in the art, various types of sensors may be used to detect products taken out of or returned to the system 10. For example, other types of sensors that may replace or assist optical sensors include weight sensors to determine the weight of products in a storage compartment before and after the products are removed, or radio frequency identification (RFID) tags and RFID readers / scanners to detect the removal and return of products.

[0063] In some embodiments, the product sensor can identify the product by detecting the shape and / or color of the product removed from the storage compartment 102. In some embodiments, the product sensor can be positioned proximate to a front portion of the storage compartment 102. In some embodiments, the product sensor can define a plane parallel to the front surface of the storage compartment 102 so as to detect when the product crosses the plane, thereby indicating that the product is removed from the storage compartment 102 or returned to the storage compartment.
