[0065] Referring to Figures 1 to 6 As shown, the present application provides a refrigerated display cabinet, which includes a cabinet body 1000, an air duct baffle 2000, a shielding assembly 3000, a control assembly, a compressor, a refrigeration fan and the like. As to other parts of the refrigerated display cabinet, those skilled in the art can design according to the needs, which are not limited herein. The interior of the cabinet body 1000 has a chamber 1100, the air duct baffle 2000 is arranged in the chamber 1100 of the cabinet body 1000, and the air duct baffle 2000 and the inner wall of the cabinet body 1000 are mutually spaced and assembled, thereby forming an air duct cavity in the chamber 1100 of the cabinet body 1000. Therefore, the space spaced out on the back side of the air duct baffle 2000 is the air duct cavity, and the space spaced out on the front side of the air duct baffle 2000 is a storage cavity for storing goods.

[0066] Continuing to refer to Figures 1 to 6 As shown, the air duct baffle 2000 is provided with a supply air hole 2100, which is used to communicate the air duct cavity and the storage cavity, and is used to guide the cold air in the air duct cavity into the storage cavity through the supply air hole 2100, thereby refrigerating the goods in the storage cavity. For example, in one embodiment, as shown in Figure 1 and Figure 2 As shown, along the longitudinal direction of the cabinet body 1000, Figure 1 and Figure 2In the longitudinal direction of the cabinet body 1000, the chamber 1100 (i.e. in the storage cavity) of the cabinet body 1000 can be provided with a plurality of display areas 1110, and adjacent display areas 1110 can be separated by shelves. At this time, the air duct cavity can also be arranged corresponding to the plurality of display areas 1110 along the longitudinal direction of the cabinet body 1000, so that the air duct cavity can cover the plurality of display areas 1110 in the longitudinal direction. Wherein, the air duct baffle 2000 can be provided with a plurality of air supply holes 2100, so that part or all of the display areas 1110 can be matched with at least one air supply hole 2100 according to the refrigeration demand, and the matched air supply hole 2100 is mainly used for refrigerating the corresponding display area 1110.

[0067] In order to adjust the refrigeration mode of the refrigeration display cabinet according to diversified refrigeration requirements, one or more shielding assemblies 3000 are arranged in the refrigeration cabinet, and the main purpose of the shielding assembly 3000 is to shield the air supply hole 2100. Wherein, the shielding assembly 3000 can be arranged in the air duct cavity, and the shielding assembly 3000 can be mainly assembled on the air duct baffle 2000, so that the shielding assembly 3000 can be configured to shield the air supply hole 2100 on demand. The shielding function of the shielding assembly 3000 can be controlled by a matched control assembly, for example, the control assembly is in control connection with the shielding assembly 3000, and the control assembly can be configured to control the movement of the shielding assembly 3000, so as to shield the air supply hole 2100 based on the movement of the shielding assembly 3000.

[0068] In one embodiment, the control assembly can be configured to control the movement of the shielding assembly 3000, so as to adjust the shielding proportion of the shielding assembly 3000 shielding the air supply hole 2100, that is, the shielding assembly 3000 shielding the air supply hole 2100 is not simply completely shielding or simply opening the entire air supply hole 2100, but needs to control the shielding assembly 3000 to shield the corresponding air supply hole 2100 according to the appropriate shielding proportion according to diversified refrigeration requirements, so that the air supply hole 2100 can be flexibly transported between the air duct cavity and the storage cavity on demand.

[0069] Therefore, the shielding ratio of the shielding assembly 3000 shielding the air supply hole 2100 can be configured between 0.01% and 100% according to requirements, and within this ratio range, the control assembly can flexibly control the movement of the shielding assembly 3000 and control the shielding state of the air supply hole 2100. Moreover, as known from the above, since the air duct baffle 2000 can be provided with a plurality of air supply holes 2100 according to requirements, the number of shielding assemblies 3000 can also be configured to be several, so that the number of air supply holes 2100 is the same as the number of shielding assemblies 3000 and can be matched one by one. Therefore, each shielding assembly 3000 can be configured to shield a corresponding air supply hole 2100, so that each air supply hole 2100 can be shielded by a specially set shielding assembly 3000. When the control assembly is synchronously controlled with a plurality of shielding assemblies 3000, the control assembly can flexibly control a plurality of shielding assemblies 3000 to shield the corresponding air supply holes 2100 at different shielding ratios according to requirements, realizing diversified and flexible control of the shielding ratio of a plurality of air supply holes 2100.

[0070] Regarding the structural design of the shielding assembly 3000, those skilled in the art can set it according to actual requirements, which is not limited herein. For example, in one embodiment, the shielding assembly 3000 can include a shielding element 3100 and a driving device 3200. The driving device 3200 serves as a power driving source, which can adopt various suitable types of motors or other driving sources. At this time, the driving device 3200 is drivingly connected with the shielding element 3100, and the driving device 3200 can be configured to control the shielding element 3100 to reciprocate along a preset trajectory, so that the air supply hole 2100 can be shielded by the movement of the shielding element 3100, and the shielding ratio of the corresponding air supply hole 2100 can be controlled.

[0071] Regarding the structural design of the shielding assembly 3000, in one embodiment, the shielding assembly 3000 can also include a transmission element 3300, which can transmit power between the driving device 3200 and the shielding element 3100. For example, the driving device 3200 is drivingly connected with the transmission element 3300, and the transmission element 3300 is drivingly connected with the shielding element 3100, so that when the driving device 3200 drives the transmission element 3300 to move, the shielding element 3100 can be driven to move by the transmission element 3300. For example, in one embodiment, the output end of the driving device 3200 is provided with a driving gear 3310, the transmission element 3300 is configured as a driving rack, the driving gear 3310 is drivingly engaged with the driving rack, and the transmission element 3300 is fixedly connected with the shielding element 3100. Therefore, by transmitting power between the driving device 3200 and the shielding element 3100 through the transmission element 3300, the entire shielding assembly 3000 can be more flexibly assembled on the air duct baffle 2000.

[0072] Regarding the control process of the refrigeration process of the above refrigerated display cabinet, the present application also correspondingly provides a refrigeration control method of a refrigerated display cabinet, which mainly can include the following steps:

[0073] Obtain the working state information of the refrigerated display cabinet, which can be used to represent the state of use of the refrigerated display cabinet, wherein the use state of the refrigerated display cabinet can be represented based on some specific indicators, for example, in one of the embodiments, the working state information can include at least one of the compressor state information, the cabinet door opening and closing information, and the chamber 1100 temperature information. The compressor state information can include the start, stop and other running states of the compressor. The cabinet door opening and closing information can include the opening, closing and switching times of the cabinet door during the use process. The chamber 1100 temperature information can include the temperature change information of the chamber 1100 in a specific period.

[0074] In addition, those skilled in the art can select other information indicators according to actual needs to measure the above-mentioned working state information, so as to use the corresponding information as the control basis for controlling the refrigerated display cabinet.

[0075] Therefore, based on the above-identified working state information of the refrigerated display cabinet as the basis, the control assembly can control the movement of the shielding assembly 3000 according to the working state information, so that the shielding assembly 3000 adjusts the shielding ratio of the air supply hole 2100 under the control of the control assembly, thereby adjusting the refrigeration state of the refrigerated display cabinet in real time and appropriately according to the obtained working state information to meet the refrigeration demand. When adjusting the refrigeration state of the refrigerated display cabinet, the fan speed of the refrigeration fan of the refrigerated display cabinet can also be controlled synchronously, for example, the refrigeration fan of the refrigerated display cabinet adjusts the fan speed according to the working state information, controls the amount of cold air introduced into the storage cavity from the air duct cavity, and thereby adjusts the refrigeration state of the refrigerated display cabinet according to the above-mentioned shielding ratio and fan speed. Wherein, optionally, the fan speed of the refrigeration fan can be configured to be between 800 r / min and 2500 r / min.

[0076] Therefore, based on at least one of the above-mentioned shielding ratio and fan speed, when adjusting the refrigeration state of the refrigerated display cabinet, different fixed modes such as rapid cooling mode, temperature equalization mode and energy saving mode can be set, so that one of the rapid cooling mode, the temperature equalization mode and the energy saving mode can be selected and executed according to the working state information, and then the refrigeration state of the refrigerated display cabinet is quickly adjusted.

[0077] The fan speed in the fast cooling mode is greater than the fan speed in the temperature equalization mode, and the fan speed in the temperature equalization mode is greater than the fan speed in the energy-saving mode. The shielding ratio in the fast cooling mode is less than the shielding ratio in the temperature equalization mode, and the shielding ratio in the temperature equalization mode is less than the shielding ratio in the energy-saving mode.

[0078] In one embodiment, the shielding ratio in the fast cooling mode can be configured to be between 0.01% and 30%, and the fan speed in the fast cooling mode can be configured to be between 1700 r / min and 2600 r / min. For example, when the fast cooling mode is executed, the shielding ratio in the fast cooling mode can be configured to be 1%, 5%, 10%, 15%, 20%, 25%, and 30%, and the fan speed can be configured to be 1700 r / min, 1800 r / min, 1900 r / min, 2000 r / min, 2100 r / min, 2200 r / min, 2300 r / min, 2400 r / min, 2500 r / min, and 2600 r / min. Therefore, after the parameters of the shielding ratio and the fan speed in the fast cooling mode are preset by the person skilled in the art, the fast cooling mode can be quickly entered when the preset condition is triggered, and the refrigeration state of the refrigerated display cabinet is automatically adjusted.

[0079] The shielding ratio in the temperature equalization mode can be configured to be between 30% and 60%. The fan speed in the temperature equalization mode can be configured to be between 1300 r / min and 1700 r / min. For example, when the temperature equalization mode is executed, the shielding ratio in the temperature equalization mode can be configured to be 3%, 35%, 40%, 45%, 50%, 55%, and 60%, and the fan speed can be configured to be 1300 r / min, 1400 r / min, 1500 r / min, 1600 r / min, and 1700 r / min. Therefore, after the parameters of the shielding ratio and the fan speed in the temperature equalization mode are preset by the person skilled in the art, the temperature equalization mode can be quickly entered when the preset condition is triggered, and the refrigeration state of the refrigerated display cabinet is automatically adjusted.

[0080] The shielding ratio in the energy-saving power consumption mode can be configured to be between 60% and 100%. The fan speed in the energy-saving power consumption mode can be configured to be between 800 r / min and 1300 r / min. For example, when the energy-saving power consumption mode is executed, the shielding ratio in the energy-saving power consumption mode can be configured to be 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%, and the fan speed can be configured to be 800 r / min, 900 r / min, 1000 r / min, 1100 r / min, 1200 r / min, and 1300 r / min. Therefore, after the parameters of the shielding ratio and the fan speed in the above-mentioned energy-saving power consumption mode are preset by the person skilled in the art, the energy-saving power consumption mode can be quickly entered when the preset condition is triggered, and the refrigeration state of the refrigerated display cabinet is automatically adjusted.

[0081] Regarding the above-mentioned triggering preset condition, the person skilled in the art can set any type of triggering preset condition according to the actual refrigeration demand, thereby meeting diversified refrigeration demands.

[0082] For example, when the compressor state information indicates that the compressor is started for the first time, the rapid cooling mode can be executed. When the compressor state information indicates that the compressor is stopped, the fan speed of the refrigeration fan is adjusted to be between 800 r / min and 1000 r / min, for example, to 900 r / min.

[0083] After the refrigerated display cabinet is started, the use state of the refrigerated display cabinet can be monitored by the corresponding temperature sensor and timer, for example, when the chamber 1100 temperature information indicates that the temperature is greater than or equal to 10°C and lasts for more than 120 min, the rapid cooling mode is executed. When the chamber 1100 temperature information indicates that the temperature is between 5°C and 10°C and lasts for more than 120 min, the temperature equalization mode is executed. When the chamber 1100 temperature information indicates that the temperature is less than or equal to 5°C and lasts for more than 120 min, the energy-saving power consumption mode is executed.

[0084] Since the refrigerated display cabinet needs to be frequently opened when selling products, the frequency of opening the cabinet door can also be monitored by the corresponding sensor, for example, when the cabinet door switch information indicates that the number of door openings within 120 min is greater than or equal to 30 times, and the chamber 1100 temperature information indicates that the temperature is greater than or equal to 5°C, the rapid cooling mode is executed. When the cabinet door switch information indicates that the number of door openings within 120 min is less than or equal to 5 times, and the chamber 1100 temperature information indicates that the temperature is less than or equal to 5°C, the energy-saving power consumption mode is executed.

[0085] In addition, when the refrigeration display cabinet needs to enter the defrosting state, it can also be switched to the defrosting mode. In one embodiment, the defrosting mode can be preset to adjust the fan speed of the refrigeration fan to 1800 r / min, increase the shielding ratio of the air supply hole 2100, reduce the opening area of the air supply hole 2100, and accelerate the defrosting. Those skilled in the art can add other operating modes according to actual needs to face diversified refrigeration control requirements, which are not limited herein.
