Description

Technical Field

[0001] The present invention relates to the technical field of intelligent kitchen appliance control, and in particular to a disinfection cabinet door closing detection method and device, and the disinfection cabinet. Background Art

[0002] Currently, after the drawer frame contacts the door switch of the disinfection cabinet, the electromagnetic lock is locked, and after hooking the drawer frame, it closes and locks the cabinet door in the form of a horizontal bar. However, to prevent the door from being fully closed and the door switch not closing, causing the disinfection cabinet to malfunction, the door switch is actually set with a travel of about 2 cm after closing. This means that if the door switch is closed when the cabinet door is not fully closed, it is possible that the electromagnetic lock is locked but not hooked on the horizontal bar behind the drawer frame. In this case, when the disinfection cabinet is operating normally, there will be a certain gap between the cabinet door and the door frame, and the cabinet door is in a state where it can be opened at any time, posing the risk of ozone leakage and high-temperature burns.

[0003] A magnetic seal is typically placed around the door frame of a disinfection cabinet to seal and hold the inner door panel in place. For flip-down doors, the hinged structure provides a significant pull to secure the door as it nears closing. For pull-out doors, the magnetic seal itself is relatively weak. When unloaded, the door and drawer rack are relatively light, allowing the magnetic seal to secure the door by holding the inner door panel in place. However, as the number of utensils placed increases, the overall mass of the door and drawer rack increases, weakening the magnetic seal until it can no longer be held in place. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a door closing detection method, device and disinfection cabinet for a disinfection cabinet. By linking the distance measuring sensor with the electromagnet, the normal closing of the disinfection cabinet door is ensured, avoiding the situation where the door control switch is closed but the electromagnetic lock does not lock the cabinet door, thereby improving the user experience.

DETAILED DESCRIPTION

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0070] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.

[0071] Example 1:

[0072] Figure 1 This is a flow chart of the door closing detection method for a disinfection cabinet provided in Example 1 of the present invention.

[0073] Reference Figure 1 The disinfection cabinet includes an electromagnet, an electromagnetic lock, a distance measuring sensor and a control panel. A probe is provided on the top of the electromagnetic lock. The distance measuring sensor can be a laser distance measuring sensor. The method includes the following steps:

[0074] Step S101: When the user's door closing operation and function operation on the control panel are detected, the distance sensor collects the current distance s from the rear crossbar of the drawer rack to the laser distance sensor;

[0075] Specifically, the door of the disinfection cabinet is in the open state by default. When the user closes the door, the number of cycles takes the initial value k=0, and then the user touches the corresponding function on the control panel, such as the disinfection mode. At this time, the laser ranging sensor starts working and collects the current distance s from the rear cross bar of the drawer rack to the laser ranging sensor.

[0076] Step S102, determining whether the current distance is less than a second set distance s1; if the current distance is greater than or equal to the second set distance s1, executing step S103; if the current distance is less than the second set distance s1, executing step S104;

[0077] Step S103, after entering the initial cycle according to the current of the electromagnet, the cycle continues until the number of cycles reaches a preset total number and then exits the cycle.

[0078] Specifically, if s>s1, the number of cycles k is incremented by one unit, and then the value of k is determined. If k<2, it is the first cycle, and the gravity sensor determines the overall weight m of the cabinet door and drawer frame assembly. Because the magnetic strength of the DC electromagnet is proportional to the current, the current of the electromagnet is adjusted synchronously according to formula (1). The electromagnet is energized to attract the cabinet door and move it in the closing direction.

[0079] Then continue to determine whether s is less than s1. If s is still greater than s1, the loop count k is incremented by one unit. At this time, k is no longer less than 2, and the next determination is entered. If k > 5, the loop count exceeds the preset total number of times, and the external display screen of the disinfection cabinet shows an E1 error, requiring the user to perform a re - closing operation. The preset total number of times is set to 5.

[0080] If k < 5, the energizing current of the electromagnet is increased by a corresponding intensity based on the previous cycle, the electromagnet is energized and adsorbs the cabinet door. At this time, the size of s is judged. If s is still greater than s1, the above - mentioned loop continues until k > 5 to exit the loop.

[0081] Step S104, lock the electromagnetic lock and collect the current round - trip time of the ultrasonic wave emitted by the probe after hitting an obstacle.

[0082] Step S105, determine whether the current round - trip time is less than or equal to the first set time. If the current round - trip time is less than or equal to the first set time, execute Step S106. If the current round - trip time is greater than the first set time, execute Step S107.

[0083] Step S106, after de - energizing the electromagnet, the disinfection cabinet works normally.

[0084] Step S107, disconnect the electromagnetic lock and continue the loop until the loop count reaches the preset total number of times and then exit the loop.

[0085] Specifically, if s < s1, lock the electromagnetic lock, the ultrasonic sensor probe synchronously emits ultrasonic waves and judges the round - trip time t. When the user closes the door for the first time, if t ≤ t1, it means that the electromagnetic lock has successfully hooked the rear crossbar of the drawer rack. If the electromagnet is not energized, the disinfection cabinet works directly. If the electromagnet is energized, after de - energizing the electromagnet, the disinfection cabinet works directly.

[0086] If t > t1, disconnect the electromagnetic lock, increment the loop count k by one unit, and then determine whether k is greater than 5. If k > 5, the loop count exceeds the preset total number of times, and the external display screen of the disinfection cabinet shows an E1 error, requiring the user to perform a re - closing operation.

[0087] If k < 5, the energizing current of the electromagnet is increased by a corresponding intensity based on the previous cycle, the electromagnet is energized and adsorbs the cabinet door. At this time, judge the size of s. If s is still less than s1, continue the above - mentioned loop until k > 5 to exit the loop.

[0088] Furthermore, the disinfection cabinet further includes a door control switch. The first set distance s2 is the distance from the rear crossbar of the drawer rack to the ranging sensor when the door control switch is closed. The second set distance s1 is the distance when the magnetic seal adsorbs the cabinet door closed with the bowl basket empty. The first set time t1 is the time for the ultrasonic wave emitted by the probe to reach the top of the rear crossbar of the drawer rack and return to be received by the probe.

[0089] Specifically, after the electromagnetic lock is locked, since the lock head of the electromagnetic lock does not reach the limit position of the rear crossbar of the drawer rack, the ultrasonic round-trip time t may be greater than t1. Therefore, t1 is appropriately adjusted to a larger value to reduce the probability of misjudgment. Thus, the round-trip time t1 can be corrected to t1 = t1 + tm, where tm is the error compensation time and can be set by the manufacturer itself. When the disinfection cabinet leaves the factory, the distance values s1 and s2, the time value t1, the overall weight m0 of the drawer rack, the empty bowl basket and the cabinet door, and the initial energizing current value i0 of the electromagnet can be preset.

[0090] Further, before step S102, the method further includes:

[0091] Step S201, determining whether the current distance is less than a first set distance; if the current distance is greater than or equal to the first set distance, then execute step S202; if the current distance is less than the first set distance, then execute step S203;

[0092] Step S202, displaying an error message on the control panel;

[0093] Step S203, determining the overall weight of the cabinet door drawer rack assembly and the energizing current of the electromagnet.

[0094] Here, the error message includes an E1 icon, which reminds the user to perform the closing operation again at this time.

[0095] Specifically, when s < s2, determine the overall weight of the cabinet door drawer rack assembly and the energizing current of the electromagnet; when s > s2, display an error message on the control panel.

[0096] Further, step S103 includes the following steps:

[0097] Step S301, when the current distance is greater than or equal to a second set distance, determining whether the number of cycles is less than a first preset number; if so, then execute step S302; if not, then execute step S303;

[0098] Step S302, after energizing the electromagnet according to the energizing current of the electromagnet and adsorbing the cabinet door, enter the next cycle;

[0099] Step S303, determining whether the number of cycles is greater than the preset total number; if so, then execute step S304; if not, then execute step S305;

[0100] Step S304, exit the loop and display an error message on the control panel;

[0101] Step S305, obtaining the energizing current of the electromagnet in the current cycle according to the energizing current of the electromagnet in the previous cycle;

[0102] Specifically, if k<5, the current flowing through the electromagnet increases to i=i+p*i, where p is the set coefficient; for example, if p=0.1, it means that the current intensity increases by 10% based on the previous cycle, so the magnetism of the electromagnet also increases by 10% compared with the last time, and then the electromagnet is energized and absorbs the cabinet door.

[0103] Step S306: After the electromagnet is energized according to the current of the electromagnet in the current cycle and the cabinet door is attracted, the next cycle is entered.

[0104] Furthermore, the disinfection cabinet further includes a gravity sensor, and step S203 includes the following steps:

[0105] Step S401, collecting the overall weight of the cabinet door and drawer frame assembly through a gravity sensor;

[0106] Step S402, calculating the current of the electromagnet according to the overall weight of the cabinet door drawer frame assembly;

[0107] The overall weight of the cabinet door and drawer frame assembly is the sum of the weights of the drawer frame, bowl basket, and cabinet door.

[0108] Furthermore, step S402 includes:

[0109] Calculate the current of the electromagnet according to formula (1):

[0110] i=m / m0*i0 (1)

[0111] Where i is the current flowing through the electromagnet, m is the total weight of the cabinet door and drawer frame assembly, m0 is the sum of the weights of the drawer frame, empty bowl basket, and cabinet door, and i0 is the initial current flowing through the electromagnet.

[0112] In this embodiment, a distance measuring sensor is set in the inner tank of the disinfection cabinet to determine the current distance from the rear cross bar of the drawer rack to the laser distance measuring sensor (drawer rack movement stroke), and the current distance s is compared with the first set distance s1 and the second set distance s2 respectively. When the cabinet door moves to the set travel range, the electromagnet at the door frame is energized to adsorb the cabinet door to close it, and then the probe set at the top of the electromagnetic lock determines whether the electromagnetic lock is locked successfully; through the linkage of the distance measuring sensor and the electromagnet, the cabinet door of the disinfection cabinet is ensured to be closed normally, avoiding the situation where the door control switch is closed but the electromagnetic lock does not lock the cabinet door, thereby improving the user experience.

[0113] Example 2:

[0114] Figure 2 This is a flow chart of another disinfection cabinet door closing detection method provided in embodiment 2 of the present invention.

[0115] Reference Figure 2, the method includes the following steps:

[0116] Step S501, when the user performs a door closing operation, the loop count k = 0;

[0117] Step S502, determine if s < s2; if yes, execute step S503; if no, execute step S504;

[0118] Step S503, determine the overall weight of the cabinet door drawer rack assembly and the energizing current of the electromagnet;

[0119] Step S504, display E1;

[0120] Step S505, determine if s < s1; if no, execute step S506; if yes, execute step S512;

[0121] Step S506, increment the loop count k by one unit, i.e., k = k + 1;

[0122] Step S507, determine if k < 2; if yes, execute step S508; if no, execute step S509;

[0123] Step S508, energize the electromagnet to adsorb the cabinet door;

[0124] Step S509, determine if k > 5; if yes, execute step S510; if no, execute step S511;

[0125] Step S510, display E1;

[0126] Step S511, increase the energizing current of the electromagnet to i = i + p * i;

[0127] Step S512, lock the electromagnetic lock, and the probe detects the round-trip time t;

[0128] Step S513, determine if t ≤ t1; if yes, execute step S514; if no, execute step S516;

[0129] Step S514, de-energize the electromagnet;

[0131] Step S516, disconnect the electromagnetic lock, k = k + 1; and continue to execute step S509.
