Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In order to solve at least the technical problems set forth in the present invention, embodiments of the present invention provide a showcase system.
Fig. 1 is a schematic structural diagram of a showcase system according to an embodiment of the present invention, and fig. 2 is a schematic functional diagram of the showcase system according to an embodiment of the present invention.
Referring to fig. 1-2, a showcase system according to an embodiment of the present invention may include: a cabinet body 1; the cabinet body is provided with a controller 2, a temperature adjusting component 3, a human body sensing component 4, a distance sensing component 5, a temperature detecting component 6 and a light component 7; the human body sensing component 4, the distance sensing component 5, the temperature detection component 6, the light component 7 and the temperature adjusting component 3 are respectively connected with the controller 2; the temperature adjustment assembly 3 includes a compressor 31. The human body sensing assembly is used for sensing human body information; the distance sensing assembly is used for detecting the distance value between the human body and the display cabinet; the temperature detection assembly is arranged in the preset range of the light assembly and used for detecting the temperature value in the preset range of the light assembly; the controller is used for acquiring the distance value between the human body and the display cabinet after acquiring the human body information through the human body sensing assembly and the distance sensing assembly; judging whether the distance value is within a preset distance threshold value, if so, triggering to start the light assembly, and acquiring a temperature value within a preset range of the light assembly after a time threshold value of the light assembly is started; and adjusting the running frequency of the compressor according to the temperature value.
In a specific implementation process, the showcase system provided by the application can be applied to places such as shopping malls and supermarkets to place and store articles. For example, the display case system can be used for keeping fresh or refrigerating in a fresh milk area and a cold drink area. Of course, the system of the present application may also be used for incubation. In order to clearly explain the technical solution of the present application, in the present embodiment, a control method is described by taking a fresh-keeping function of a showcase system as an example.
For example, in a display case system, items can be placed on the body of the display case. In a market or a supermarket, when people pass through the display cabinet and want to take articles in the display cabinet, the human body sensing component senses human body information and sends the human body information to the controller. After the controller receives the human body information, a person is determined to pass through the display device, and the distance value between the human body and the display cabinet is obtained through the distance sensing assembly. When the person is judged to be within 3 meters of the display cabinet, the starting light assembly is turned on, so that the person can more clearly view the articles in the display cabinet. Wherein, human response subassembly can be human identification sensor, and apart from the response subassembly can be distance sensor, and light subassembly can be LED lamp etc. and do not do specific limit here, and wherein, 3 meters are to the example of presetting apart from the threshold value, and are not the restriction. After the light assembly is started, heat can be emitted to influence the temperature value of the display cabinet. After the light assembly starting time threshold value (for example, after 60 s), a temperature value within a preset range of the light assembly is obtained, and the operating frequency of the compressor 31 is adjusted according to the temperature value. Wherein, the temperature value is detected by temperature detect assembly, for the accuracy of promotion detection, in this embodiment, can set up temperature detector near the LED lamp, for example, closely adjacent LED lamp 3mm department etc..
In some embodiments, optionally, the controller is specifically configured to determine whether the temperature value reaches a temperature threshold, and if the temperature value reaches the temperature threshold, maintain the operating frequency of the compressor; and if the temperature value exceeds the temperature threshold value, correspondingly adjusting the running frequency of the compressor.
For example, the temperature threshold of the showcase is set to [8,12] ° c, and when the temperature value detected by the temperature detector is judged to be within the temperature threshold range, the current operation frequency of the compressor is maintained; and when the temperature value is judged to be larger than the maximum value of the temperature threshold value or smaller than the minimum value of the temperature threshold value, correspondingly adjusting the operating frequency of the compressor. After the light assembly is turned on, the light assembly generates heat to cause the temperature value to rise, therefore, the temperature value may be larger than the maximum value of the temperature threshold value, at the moment, the operation frequency of the compressor is adjusted and accelerated to enable the temperature value to be maintained within the temperature threshold value, for example, the operation frequency of the compressor can be increased by 5Hz-10Hz, the fan frequency corresponding to the inner fan connected with the compressor is increased along with the logic operation, the refrigeration effect in the display cabinet is improved, and the refrigeration loss caused by the heat emitted by the LED light assembly is reduced.
In some embodiments, optionally, the controller is further configured to trigger turning off the light assembly if the distance value exceeds a preset distance threshold; and adjusting the running frequency of the compressor according to the temperature value when the light assembly is turned off.
For example, when the distance value between the human body and the display cabinet is judged to be more than 3 meters, the explaining person leaves the display cabinet, and the control triggers the light assembly to be turned off. At this time, the operating frequency of the compressor is adjusted according to the temperature value detected when the light assembly is turned off.
In some embodiments, optionally, the controller is specifically configured to determine whether the temperature value at the time of shutdown exceeds a temperature threshold; and if the temperature value during closing exceeds the temperature threshold value, reducing the operating frequency of the compressor according to the first reduction frequency value.
For example, when the temperature value at the time of shutdown exceeds the temperature threshold value, the operating frequency of the compressor is reduced and the fan frequency of the inner fan is reduced according to the first reduction frequency value. If the fan frequency is operated in the frequency range of 50Hz-70Hz, the operation can be continuously maintained by reducing 10Hz after the LED light assembly is closed until the temperature value is reduced to the temperature threshold value; in other frequency bands, operation may be maintained until the temperature threshold is lowered to operate logically.
In some embodiments, optionally, the controller is further configured to: if the temperature value during closing is smaller than the temperature threshold value, reducing the running frequency of the compressor according to a second reduction frequency value; the second reduced frequency value is greater than the first reduced frequency value.
For example, when the temperature value at the time of shutdown is lower than the temperature threshold value, the operating frequency of the compressor is reduced and the fan frequency of the inner fan is reduced according to the second reduction frequency value. If the fan frequency is operated in the frequency range of 50Hz-70Hz, the operation can be continuously maintained by reducing 20Hz after the LED light assembly is closed until the temperature value is reduced to the temperature threshold value; in other frequency bands, the operation can be reduced by 5Hz-10Hz, and the temperature in the display cabinet is kept.
In a specific working process, a light sensing sensor can be arranged, and when the light sensing sensor detects that the light component is continuously turned on in a preset time period, such as 8:00 in the morning to 10:00 in the evening, and the light is lower than a light threshold value. For example, in a dark corner, the lights may be turned on continuously during working hours in order to enhance the customer experience.
In some embodiments, optionally, a manual control module is further disposed on the cabinet body; the manual control module is connected with the controller and used for manually controlling the opening and closing of the light assembly.
For example, a manual mode may be set, and when the manual mode is selected by the customer, the light assembly and the fan operating frequency may be adjusted according to the manual mode. The lamp operation may be forced on and off by a manual mode.
In some embodiments, optionally, the method further includes: a display component 8; the display component is connected with the controller.
For example, a display may be provided to display the temperature value, time, display items, fan operating frequency, etc. of the display case.
In some embodiments, optionally, the method further includes: at least 2 instant freezing compartments, instant freezing completed storage areas; an instantaneous freezing chamber for instantaneous freezing of the target item; and the instant freezing finished storage area is used for storing the target object after the instant freezing is finished.
For example, for the convenience of use, at least 2 instant freezing chambers and instant freezing finished storage areas can be arranged in the display cabinet; an instantaneous freezing chamber for instantaneous freezing of the target item; and the instant freezing finished storage area is used for storing the target object after the instant freezing is finished.
