Description

[0001] This application is a divisional application of the Chinese Patent Application No. 201880004352.0 with the title of “Hygienic system for portable packaged food containers” filed on May 13, 2019. The parent application of the above corresponds to the PCT International Application No. PCT / CN2018 / 086468 with the international filing date of May 11, 2018. TECHNICAL FIELD

[0002] This document relates generally to device hygiene, and more specifically to methods and apparatus for implementing automatic cleaning and / or sanitizing cycles on a closed space, such as an interior, of a box for containing packaged food, and a hygienic system for portable packaged food containers. BACKGROUND

[0003] Small and closed spaces, such as the interior of a food delivery box, are difficult to clean and / or sanitize. For example, boxes used to deliver packaged food, such as ready-to-eat food ordered by a customer from a restaurant, need to be cleaned and sanitized on a regular basis to ensure food hygiene. This can be done by manually spraying a chemical agent onto the surfaces of each delivery box. The quality and thoroughness of such manual cleaning and / or sanitizing depends on the individual performing the process, and is therefore inconsistent, as there is no mechanism to ensure that the entire surface is covered and / or in a substantially uniform manner. The two-step cleaning and sanitizing process makes each cycle more complex and inconsistent. Furthermore, manual operation does not provide an objective record showing that the hygiene process was followed routinely. SUMMARY

[0004] The system can automatically implement a hygiene cycle on a closed space, such as an interior, of a box suitable for storing and / or carrying packaged food. The system can include a hygiene device that can be attached to the box to implement the hygiene cycle.

[0021] The following detailed description of the subject matter refers to the drawings, which are by way of illustration, show specific aspects and embodiments of the subject matter. These embodiments are described in sufficient detail to enable those skilled in the art to practice the subject matter. References to "an," "one," or "the" embodiment throughout this disclosure are not necessarily to the same embodiment, and, moreover, such references constitute

[0022] This document discusses, inter alia, a system for automatically implementing and automatically logging hygiene cycles in an enclosed space. The system can be configured as a portable clean-in-place ("CIP") system. The hygiene cycle log can include various information collected by the system, and can be transmitted to an analysis center over a telecommunications network.

[0023] ​In this document, "sanitation" can include cleaning, sanitizing, or cleaning and sanitizing (C&S). For example, a "sanitation agent" can include a cleaning agent, a sanitizing agent, or a cleaning and sanitizing (C&S) agent; a "sanitation cycle" can include a cleaning cycle, a sanitizing cycle, or a cleaning and sanitizing (C&S) cycle; a "sanitation process" can include a cleaning process, a sanitizing process, or a cleaning and sanitizing (C&S) process.

[0024] Examples of an enclosed space include an enclosed space in a closed box used to carry or store packaged ready-to-eat food. An example of such a box includes a food delivery box used to carry cooked food from a kitchen to a dining location located away from the kitchen. A sanitation process can be established for such a box to ensure food safety (e.g., in accordance with relevant regulatory requirements). When the process is performed manually, it is difficult to ensure compliance, and there is no objective evidence of compliance recorded.

[0025] The present system provides an intelligent system that can spray a sanitation agent onto the surfaces of an enclosed space in a substantially uniform distribution under automatic control for implementing a sanitation cycle periodically or according to other specified schedules and / or criteria. In some embodiments, a 2-in-l sanitation agent (also referred to as a C&S agent) combines cleaning and sanitizing into an efficient single step. The present system also automatically collects sanitation cycle information, and transmits the collected information to one or more specified receiving locations for analysis and monitoring.

[0026] Existing sanitation systems that are intended for large spaces and require a large amount of power to operate, a large amount of water to rinse, and compressed air to dry, are not suitable for small spaces, such as a food delivery box that can be small enough to be carried by hand and / or an electrically powered scooter or motorcycle. The present system can be battery powered and portable, such as can be easily attached to a food delivery box to perform controlled spraying of a sanitation agent onto the interior surfaces of the food delivery box when the food delivery box is empty. In one embodiment, the present system uses a single nozzle that is configured to work with a diaphragm pump to spray the sanitation agent atomically to ensure that the sanitation agent covers all surfaces of the enclosed space, such as the cavity of a rectangular box having six flat surfaces.

[0027] In various embodiments, the present system can include a control system that receives a command and initiates a sanitation cycle in response to the command. The command can be received by the system from a remote device via a communication link. In response to the sanitation cycle being initiated, the electronic circuitry of the present system generates a signal to initiate the diaphragm pump to spray, resulting in a substantially uniform distribution of the sanitation agent on all surfaces of the enclosed space. The electronic circuitry can control the automatic performance of the sanitation cycle, record the time and / or other sanitation cycle information of the sanitation cycle, and transmit the recorded information, including the time, to an analysis center.

[0028] In various embodiments, the sanitizing agent can include one or more chemicals in liquid form. Examples of sanitizing agents include a cleaner, a disinfectant, or a selected two-in-one C&S agent, such that when sprayed into an enclosed space using the present system, a dose distributed on the surfaces of the enclosed space can produce results that meet the relevant regulatory requirements for cleaning and disinfecting efficacy. This dose distribution can be achieved by configuring the nozzle and diaphragm pump to provide chemical fogging and determining the duration of spraying for each sanitizing cycle.

[0029] While the sanitizing system for a food delivery box is specifically discussed as an example in this document, the present subject matter is not limited to such an application, but can be used to apply a liquid and / or gas into any enclosed space for purposes including, but not limited to, cleaning and disinfecting the enclosed space. Some examples of devices having a cavity that can be cleaned and disinfected by applying the present subject matter include a refrigerator, a microwave, a food container of any shape, a container of non-food items that need to be cleaned and disinfected, a storage and / or delivery box (not limited to food storage and / or delivery), and a dishwasher. In addition, the present subject matter is not limited to spraying a liquid sanitizing agent, but can also be used to spray various other liquids or gases, such as a pest control agent.

[0030] Figure 1 is a block diagram showing an embodiment of a system 100 for cleaning and disinfecting a box 101. The box 101 can include any container having a cavity that needs to be cleaned and disinfected. In the illustrated embodiment, the box 101 is a rectangular box having a flat rectangular bottom 102 (only the edges are shown in Figure 1 ), a lid (or cover) 103, and four sides. The four sides include a front side 105 (only the edges are shown in Figure 1 ), a back side 104, and two lateral sides 106A and 106B (only the edges are shown in Figure 1 ) each coupled between the front side 105 and the back side 104. The lid 103 is connected to the back side 104 by hinges 107A and 107B. In various embodiments, the lid 103 is connected to the back side 104 by one or more hinges. The box 101 can be securely closed using a locking mechanism (not shown) that locks the lid 103 in a closed position. When the lid 103 is in the closed position (as shown in Figure 1 ), a closed space is formed by the inner surfaces of the box 101 including the bottom 102, the front side 105, the back side 104, the lateral sides 106A and 106B, and the lid 103. This closed space can be cleaned and disinfected by using the present subject matter.

[0031] Examples of box 101 are food storage and / or delivery boxes, such as portable food delivery boxes. In various embodiments, box 101, as a food delivery box, can be carried by hand and / or attached to a vehicle such as a bicycle, moped, or motorcycle. For example, the food delivery box can be attached to a vehicle with the rear side 104 facing the vehicle's forward direction of movement. In various embodiments, box 101 is used to contain packaged food without allowing direct contact between the food and the inner surface of the box. When used correctly, no solid or liquid food residue or stains should be left on the inner surface of box 101 so that rinsing is not required for cleaning. In the event of accidental food leakage, manual cleaning may be necessary.

[0032] System 100 may be an automated sanitation system, including a sanitation device 110, a user interface device 120, and an analysis center 124 that can communicate with the user interface device 120 via a network 122. The sanitation device 110 may be attached to a housing 101. In some embodiments, the sanitation device 110 is configured to be detachably attached to the housing 101. In the illustrated embodiment, the sanitation device 110 includes a container unit 111 for containing a sanitary agent and a nozzle for controlling the sanitary agent flow. Figure 1 The document shows (not shown) the delivery controller unit 112, the conduit 113 between the container unit 111 and the controller unit 112, and the conduit 114 between the controller unit 112 and the nozzle. It should be understood that, as shown in this document... Figure 1 As shown in other figures, the arrangement of system components (e.g., how the components of sanitary device 110 are physically arranged, housed, and attached to box 101) is illustrated by way of example rather than limitation. Such an arrangement may be determined based on design considerations such as the specific shape and size of box 101, the location where box 101 will be placed, and / or how box 101 will be transported.

[0033] The user interface device 120 can send and receive information via one or more wireless communication links, such that it can present instructions to a user of the box 101 and receive confirmations and / or commands from the user. In this document, a "user" includes a person using the system 100 to clean and sanitize the box 101. When the box 101 is a portable food delivery box, the user can be a delivery person (also referred to as a "driver," "rider," etc.) assigned the task of cleaning and / or sanitizing the box. Such a delivery person can include anyone carrying the box by hand and / or using any vehicle. The user interface device 120 can communicate with the hygiene device 110 via a wireless communication link 121 (e.g., using Bluetooth technology) and can communicate with a network 122 via another wireless communication link 123 (e.g., the Internet or a cellular network over Wi-Fi). In various implementations, the user interface device 120 can present instructions to the user using a touchscreen and / or a speaker, and can receive confirmations and / or commands from the user using a touchscreen and / or a microphone. For example, communicating with the user using a speaker and a microphone (e.g., a headset provided with a microphone) allows hands-free operation at least to some extent. In various implementations, the user interface device 120 includes a mobile device, such as a cellular phone or a tablet computer.

[0034] The analysis center 124 can represent one or more data analysis and / or monitoring facilities in communication with many boxes of a commercial organization, such as all food delivery boxes of a food delivery company or a subset, such as all food delivery boxes within a region or a subsidiary of a food delivery company. This allows the organization to efficiently and effectively manage the cleaning and / or sanitization of the boxes, such as for ensuring food safety and / or meeting regulatory requirements.

[0035] The network 122 can represent any network including, but not limited to, a telecommunications network, a local network, the Internet, or the Internet of Things (IoT). In various implementations, the network 122 includes an IoT, with the user interface device 120 and the analysis center 124 as part thereof, respectively. In some implementations, the hygiene device 110 can communicate with the network 122 directly (without the user interface device 120) via another wireless communication link 127 (e.g., a Wi-Fi or cellular network). This allows direct communication between the analysis center 124 or other operations control or management center and the hygiene device 110 when communication with the user interface device 120 via link 121 and / or 123 is not available for any reason. In some implementations, the hygiene device 110 can be configured to be part of an IoT, and the network 122 can represent an IoT, with the hygiene device 110, the user interface device 120, and the analysis center 124 all as part thereof.

[0036] Figure 2is a block diagram illustrating an embodiment of a hygiene device 210 that represents an example of components of the hygiene device 110. The hygiene device 210 can include a dose container 230, a conduit 213, a pump 231, a conduit 214, a nozzle 232, a control circuit 233, and a power source 234.

[0037] The dose container 230 contains a hygiene agent. Depending on the purpose of conducting a hygiene cycle, the hygiene agent can be a liquid chemical agent that has only a cleaning effect, only a disinfecting effect, or both cleaning and disinfecting effects. The hygiene agent that has both cleaning and disinfecting effects can be referred to as a two-in-one hygiene agent or a two-in-one C&S agent. Using such a two-in-one hygiene agent can perform each C&S hygiene cycle with a single spraying action. In various embodiments, the dose container 230 includes a refillable bottle or a disposable bottle that is suitable for containing the hygiene agent. The pump 231 can receive the hygiene agent from the dose container 230 through the conduit 213 and deliver the hygiene agent to the nozzle 232 through the conduit 214. An example of the pump 231 includes a diaphragm pump. The nozzle 232 works with the pump 213 to create a spray of the hygiene agent in an enclosed space of a cartridge, such as the cartridge 101, to cause a substantially uniform distribution of the hygiene agent on the inner surfaces of the cartridge. In one embodiment as a specific example discussed in this document, the nozzle 232 includes a single nozzle that is incorporated into the bottom of the cartridge, e.g., inserted into the cartridge through a hole in the geometric center of the cartridge bottom. In various embodiments, the nozzle 232 can include one or more nozzles incorporated into the bottom, the lid, and / or each of the four side portions of the cartridge to create a spray of the hygiene agent in the cartridge, thereby causing a substantially uniform distribution of the hygiene agent on the inner surfaces of the cartridge. The control circuit 233 can include an electronic circuit that is configured to control the conduct of a hygiene cycle. The power source 234 provides power for the operation of the hygiene device 210. The power source 234 can include one or more rechargeable and / or non-rechargeable batteries.

[0038] In one embodiment, the components of the hygiene device 210 are arranged and attached to the cartridge as shown in Figure 1 Fig. 2B. In various embodiments, the components of the hygiene device 210 can be arranged and coupled to the cartridge in any manner that ensures the portability of the cartridge.

[0039] Figure 3 is a diagram illustrating an embodiment of a portion of the hygiene device 110 as seen from a rear view of the cartridge 101. Figure 3The components of the box 101 shown include a bottom 102 (edge ​​only shown), a cover 103 (edge ​​only shown), lateral sides 106A (edge ​​only shown) and 106B (edge ​​only shown), and a rear side 104. Figure 3 The components of the sanitary device 110 shown include a container unit 111, a pipe 113, a controller unit 112, and a pipe 114.

[0040] Figure 4 This is a diagram showing an embodiment of the bottom 102 of the cartridge 101 configured to accommodate the nozzle. Figure 4 The components of the box 101 shown include a bottom 102, a cover 103 (only the two edges are shown), a rear side 104, a front side 105 (only the two edges are shown), and lateral sides 106A (only the two edges are shown) and 106B. The bottom 102 includes an opening 440, which is sized and shaped to allow placement of a nozzle, such as nozzle 232. The bottom 102 also includes a recess 441 to receive a portion of a conduit 114 connected to the nozzle.

[0041] Figure 5 This is a diagram showing an embodiment of a portion of the sanitary device 110 as seen in a cross-sectional view of the box 101. Figure 5 The components of the box 101 shown include a bottom 102 with a hole 440 and a groove 441, a cover 103, and lateral sides 106A and 106B. Figure 3 The components of the sanitary device 110 shown include a container unit 111, a pipe 113, a pipe 114, and an example of a nozzle 232, which is shown as a nozzle 532 that generates a spray that distributes the sanitary agent onto the inner surface of the box 101.

[0042] Figure 6 This is a diagram illustrating an embodiment of a controller unit 612, representing an example of a controller unit 112. (As shown...) Figure 6 The controller unit 612 shown illustrates an example of the placement of its main components, which include a pump 631 (representing an example of pump 231), a control circuit 633 (representing an example of control circuit 233), a battery pack 634 (representing an example of power supply 234), a pipe connector 643 configured to be connected to pipe 113, and a pipe connector 644 configured to be connected to pipe 114.

[0043] Figure 7 This is a block diagram illustrating an embodiment of control circuit 733, representing an example of control circuit 233. Control circuit 733 may include communication circuit 750, power switch 751, hygiene cycle management circuit 752, monitoring circuit 753, and power management circuit 754.

[0044] The communication circuit 750 provides communication between the user interface device 120 and the hygiene device 110 via the wireless communication link 121, e.g. using Bluetooth technology. In various embodiments, the communication circuit 750 transmits data collected by the hygiene device 110 to the user interface device 120, receives commands from the user interface device 120 to control the operation of the hygiene device 110, and transmits signals indicative of the operating status of the hygiene device 110 to the user interface device 120. The user interface device 120 can act as a relay device for communication between the hygiene device 110 and the analysis center 124 (or any other operation control or management center) over the network 122. In some embodiments, the communication circuit 750 also provides communication between the network 122 and the hygiene device 110 via the wireless communication link 123, e.g. using Wi-Fi or a cellular network. The communication circuit 750 can transmit data collected by the hygiene device 110 to the analysis center 124, receive commands from the analysis center 124 to control the operation of the hygiene device 110, and transmit signals indicative of the operating status of the hygiene device 110 to the analysis center 124 over the network 122 without using the user interface device 120 as a relay device.

[0045] The power switch 751 can comprise any switch suitable for switching power on and off. This allows the user to switch the hygiene device 110 on and off.

[0046] The hygiene cycle management circuit 752 can initiate and control hygiene cycles according to a programmed schedule, criteria, and / or user commands. In various embodiments, the hygiene cycle management circuit 752 can be configured to initiate hygiene cycles periodically (e.g., every 4 hours) or according to a specified (e.g., programmable) schedule (e.g., at 10:30 AM, 2:00 PM, 5:00 PM, and 8:00 PM). The hygiene cycle management circuit 752 can also be configured to initiate hygiene cycles in response to user commands (e.g., overriding the specified schedule). The user commands can include commands sent from the user interface device 120 and received by the communication circuit 750. In various embodiments, the hygiene cycle management circuit 752 can confirm that the cartridge 101 is empty and the lid 103 is closed, and can begin spraying the hygiene agent upon making the confirmation. For example, the hygiene cycle management circuit 752 can send a confirmation request signal to the user interface device 120 through the communication circuit 750, and receive a confirmation response signal from the user interface device 120 confirming that the cartridge 101 is empty and the lid 103 is closed. The user interface device 120 can present the confirmation request signal as an audible and / or visual message to the user, and receive a response from the user as the confirmation response signal. The confirmation response signal can serve as a command to begin spraying the hygiene agent, i.e., the hygiene cycle management circuit 752 can begin spraying the hygiene agent upon receiving the confirmation response signal. In various embodiments, the hygiene cycle management circuit 752 can also control the execution of the hygiene cycle after it is initiated, including controlling the pumping of the hygiene agent during the hygiene cycle. For example, the hygiene cycle management circuit 752 can control the duration of the hygiene agent pumping by timing the pumping and ending the pumping upon expiration of a specified time interval.

[0047] The monitoring circuit 753 can record information indicative of the performance of each hygiene cycle and send the recorded information to the network 122 (in other words, "upload data to the cloud"). In various embodiments, the recorded information can include information identifying the box 101 (e.g., a serial number), the user (e.g., the delivery person using the box), the time of the hygiene cycle (e.g., the start, end, and / or actual spraying time), and / or the location where the hygiene cycle was performed. In various embodiments, the recorded information is sent to the network 122 so that the analysis center 124 can analyze the recorded information and send instructions and / or alerts to the user interface device 120 based on the results of the analysis (e.g., to ensure compliance with hygiene procedures), periodically receive recorded information from all delivery boxes equipped with hygiene devices (e.g., company-wide, regionally, or nationally), periodically (e.g., monthly) report to management (e.g., a designated person or team) on the performance of hygiene cycles of delivery boxes (e.g., statistics), and / or send instructions from management to each user and / or each team leader managing multiple users. In various embodiments, the monitoring circuit 753 can also monitor the status of the hygiene cycle and notify the user by sending information to the user interface device 120 indicative of the status of the hygiene cycle. When the sent information indicates that the hygiene cycle is complete, the user interface device 120 can present instructions to the user to open the lid 103 to allow natural drying or wiping of the inner surfaces of the box 101 with a paper towel (e.g., to comply with regulatory requirements) and / or perform certain other tasks that comply with relevant regulatory requirements.

[0048] The power management circuit 754 can manage the operation of the power source 234 and control the distribution of power to the various components of the hygiene device 110 that require power to operate (e.g., the pump 231 and the control circuit 233 or 733). When the power source 234 includes one or more batteries, the power management circuit 754 can monitor the remaining level of the one or more batteries and generate a battery level alert signal in response to the level falling below a battery level threshold. The power management circuit 754 can send the battery level alert signal to the user interface circuit 120 through the communication circuit 750 to alert the user to replace or recharge the one or more batteries of the power source 234. In one embodiment, the user interface device 120 periodically alerts the user to replace the batteries or recharge the batteries (e.g., every week).

[0049] In some embodiments, the control circuit 733 is configured to determine the location of the hygiene device 110 using a positioning system such as a global positioning system (GPS) or a location-based service (LBS). This allows for tracking of the hygiene device 110 and using its location trajectory to determine whether a hygiene cycle should be performed. The hygiene cycle management circuit 752 can use the location of the hygiene device 110 as one of the criteria to initiate a hygiene cycle. For example, when the bin 101 arrives at a scheduled hygiene cycle, the hygiene cycle management circuit 752 can track the location of the attached hygiene device 110 and have the bin 101 with the hygiene device 110 return after delivering food to the facility initiate a hygiene cycle while preparing food for delivery. Information recorded and transmitted by the monitoring circuit 753 about the hygiene cycle can also include the location at which the hygiene cycle was performed. The control circuit 733 and / or the analysis center 124 can analyze the recorded information to determine whether the hygiene process was complied with, for example, by determining the number of food deliveries between two hygiene cycles (as monitored by tracking the location of the hygiene device 110). The control circuit 733 can also transmit information indicating the location of the hygiene device 110 to the network 122 to allow tracking of the hygiene device 110 by the analysis center 124 and / or other operations control or management centers for various other purposes. For example, the location of the hygiene device 110 can be tracked to record and analyze the route of food deliveries to improve timing or efficiency, or to monitor whether the hygiene device 110 is deployed to comply with the hygiene process.

[0050] Figure 8 is a flowchart illustrating an embodiment of a method 860 for cleaning and sanitizing a bin, such as the bin 101. In one embodiment, the system 100 is configured to perform the method 860. In one embodiment, a user interface device, such as the user interface device 120, is configured to control the performance of the method 860. For example, the user interface device can comprise a cellular phone, and an application is installed on the cellular phone to control the performance of the method 860. The application can present reminders and instructions to the user before, after, and during each hygiene cycle.

[0051] At 861, the bin is verified to be empty. If the bin is not empty (e.g., the bin contains food), the contents must be removed before the hygiene cycle can begin. If the bin is not empty because it is soiled (e.g., by a food spill), the bin can be manually cleaned (e.g., using a paper towel to wipe away solid or liquid food spillage). The bin can then be verified to be empty.

[0052] At 862, in response to a command indicating that the bin is verified to be empty, an automatic hygiene cycle is initiated. The hygiene cycle can be performed automatically using a battery-powered portable hygiene device (e.g., the hygiene device 110) that is attached to the bin.

[0053] At 863, information related to the execution of the hygiene cycle is recorded by the battery-powered portable hygiene device. Such information is indicative of whether the hygiene process was complied with, for example to ensure food safety and / or to meet regulatory requirements.

[0054] At 864, the recorded information is transmitted to the analysis center, for example by uploading data representing the recorded information to a network. This ends the hygiene cycle. In various embodiments, the transmission of the recorded information can be triggered by the end of each hygiene cycle (periodically), by a data transmission command sent from the user interface device, and / or by detecting non-compliance with the hygiene process. The recorded information can be transmitted to the analysis center directly from the battery-powered portable hygiene device and / or via the user interface device.

[0055] In various embodiments, upon completion of the hygiene cycle, the inner surfaces of the box will be dried by the user. This can be done by opening the lid of the box to allow for natural air drying. Alternatively, this can be done by opening the lid of the box and wiping all the inner surfaces of the box (for example, using a paper towel), for example when time or weather does not allow for air drying. When the box is used for food delivery, no liquid (i.e., hygiene agent) should be left in the box when loading the packaged food for the next food delivery.

[0056] In various embodiments, the exterior of the box should also be cleaned periodically. Such cleaning can be performed manually.

[0057] In various embodiments in which the container of the hygiene agent is refillable, the container is cleaned before each refill or after a specified number of refills. Other parts of the hygiene device (for example, the nozzle and / or the tubing) should also be cleaned periodically or as needed.

[0058] Figure 9 is a diagram showing an embodiment of a user interface device 920 which can represent the user interface device 120. In the illustrated embodiment, the user interface device 920 is a cell phone on which a hygiene application 970 is installed. The cell phone is carried by each delivery person (or other person) responsible for complying with the hygiene process.

[0059] In various embodiments, the functions performed by the application 970 through the cell phone 920 can include functions selected from the following examples:

[0060] • presenting food safety tips for the home delivery of cooked food;

[0061] • displaying a training video on the hygiene process for the home delivery of cooked food;

[0062] • reminding the user that a hygiene cycle is starting (with an audible and / or visual message);

[0063] • instructing the user to check whether the box is empty;

[0064] • receiving confirmation from the user that the box is empty;

[0065] • triggering spraying of the hygiene agent during each hygiene cycle;

[0066] • recording information related to each hygiene cycle;

[0067] • sending the recorded information to a network (by uploading data representing the recorded information to an analysis center via the network, due to a transmission command from the user at the end of each hygiene cycle (periodically), by detecting a failure in compliance with the hygiene process, and / or by detecting a trigger

[0068] • receiving feedback information from the analysis center (generated automatically by the data analysis center and / or feedback information generated by one or more

[0069] • detecting each non-compliance with the hygiene process;
