Technical Field
[0001] This utility model relates to the field of display cabinet technology, specifically a display cabinet with dual temperature switching capability. Background Technology
[0002] Dual-temperature display cases, capable of providing two different temperature storage environments simultaneously, are widely used in homes, convenience stores, laboratories, and other settings, effectively meeting the storage needs of various items such as beverages, fresh produce, medicines, and reagents. However, existing dual-temperature display cases still have several technical limitations in practical applications, making it difficult to fully meet users' dual demands for space flexibility and temperature accuracy. The main problems are concentrated in the following two aspects: First, dual-temperature display cabinets typically use fixed partitions to divide the internal space. The partition dimensions are preset at the factory and cannot be adjusted according to changes in the quantity and volume of items stored by the user, resulting in low space utilization. Second, the refrigeration system often adopts either "dual evaporator independent refrigeration" or "single evaporator fixed section refrigeration" mode. The former increases equipment costs and energy consumption, while the latter cannot accurately match the refrigeration capacity according to changes in partition dimensions. Therefore, it is difficult to achieve dynamic matching of "partition volume-refrigeration capacity", which fails to meet the user's core needs for dynamic adjustment of storage space and precise temperature protection for different items. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model provides a display cabinet with dual temperature switching, which solves the problems described in the background art above.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a display cabinet with dual temperature switching, including a display cabinet body and a placement cavity opened on the inner wall, and also including an adjustment component, the adjustment component being disposed inside the placement cavity, an evaporator being installed in the placement cavity, the adjustment component being connected and installed with the evaporator, and used to control the amount of refrigerant introduced according to the dual temperature range inside the display cabinet body; A sliding component is provided, which is located on the inner top of the display cabinet body. The sliding component includes a heat-insulating partition that is adapted to the inner cavity of the display cabinet body. The heat-insulating partition can slide along the inner top to divide the internal dual temperature of the display cabinet body and meet the usage requirements.
[0005] Furthermore, the sliding assembly also includes a slide groove, an electric slide rail, and a slider. The slide groove is located on the top of the display case body, the electric slide rail is installed inside the slide groove, and the slider is slidably mounted on the electric slide rail. The heat insulation partition is fixedly installed below the slider.
[0006] Furthermore, a sealing component is provided on the side of the insulation partition, a position sensor is embedded on one side of the insulation partition, and temperature sensors are embedded on both sides of the insulation partition.
[0007] Furthermore, the sealing assembly includes an installation cavity, a sealing airbag, a micro air pump, and an exhaust valve. The installation cavity is located on the side of the thermal insulation partition. The sealing airbag is installed inside the installation cavity. A micro air pump is installed on one side of the sealing airbag in the installation cavity, and an exhaust valve is provided on one side of the sealing airbag.
[0008] Furthermore, two sets of sealing doors are slidably installed on the front side of the display cabinet body, and a sealing strip is provided between the two adjacent sets of sealing doors. A placement groove is provided at the bottom of the display cabinet body.
[0009] Furthermore, a compressor is installed inside the placement tank, a condenser is installed on one side of the compressor via a pipe, and an expansion valve is installed on one side of the condenser via a delivery pipe.
[0010] Furthermore, the expansion valve is equipped with a double-way solenoid valve via a pipeline. An adjustment component is provided on one side of the double-way solenoid valve, and a capillary tube is installed at the other end of the double-way solenoid valve.
[0011] Furthermore, the second capillary tube is connected to one end of the evaporator, and the other end of the evaporator is connected to the compressor.

[0013] Furthermore, the evaporator has an "S" shaped structure, with the other end of the branch pipe connected to the bend at the bottom of the evaporator.
[0014] This utility model has the following beneficial effects: 1. By installing a sliding component on the inner top of the display cabinet body, the electric slide rail is powered on and causes the slider in the slide groove to slide along the track, thereby driving the insulation partition below the slider to move synchronously. The position sensor on one side of the insulation partition monitors the relative position of the insulation partition and the display cabinet body in real time. Then, the interior of the display cabinet body is divided by a sealing component to block the air convection between the two areas inside the display cabinet body and avoid temperature crosstalk. The coordinated operation of the sliding component and the sealing component creates an independent and controllable storage environment for the two cavities inside the display cabinet body through the dual effect of "flexible space division + reliable temperature isolation", thus precisely meeting the storage needs of people for different items.
[0015] 2. By installing an adjustment component at the bottom of the evaporator, the evaporator has an "S"-shaped structure. Multiple bends at the bottom of the evaporator are connected to the distribution pipes of the adjustment component. The control system controls the opening and closing of the corresponding distribution pipes by opening different numbers of one-way solenoid valves. By controlling the number of one-way solenoid valves and the path switching of the two-way solenoid valves, the refrigerant input and the heat exchange area of the evaporator are precisely regulated, ultimately achieving stable dual-temperature control of "matching different cooling capacities to different volume areas".

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is based on Figures 1-6 This invention describes a display cabinet with dual-temperature switching capabilities provided in an embodiment of the present invention.
[0021] Please see Figures 1-6 This utility model provides a technical solution: a display cabinet with dual-temperature switching capability, including a display cabinet body 1 and a placement cavity 102 opened in the inner wall, and an adjustment component 8, which is disposed inside the placement cavity 102. An evaporator 10 is installed in the placement cavity 102, and the adjustment component 8 is connected to the evaporator 10 for controlling the amount of refrigerant introduced according to the dual-temperature range inside the display cabinet body 1. A sliding component 12 is disposed at the inner top of the display cabinet body 1, and includes a heat-insulating partition 1204 adapted to the inner cavity of the display cabinet body 1. The heat-insulating partition 1204 can slide along the inner top to divide the dual-temperature range inside the display cabinet body 1 to meet usage requirements. The sliding component 12 also includes a slide groove 1201, an electric slide rail 1202, and a slider 1203. The slide groove 1201 is open... Located on the top of the display cabinet body 1, the slide 1201 contains an electric slide rail 1202, and a slider 1203 is slidably mounted on the electric slide rail 1202. The heat insulation partition 1204 is fixed below the slider 1203. A sealing component 13 is provided on the side of the heat insulation partition 1204. A position sensor 14 is embedded on one side of the heat insulation partition 1204, and temperature sensors 15 are embedded on both sides of the heat insulation partition 1204. The sealing component 13 includes an installation cavity 1301, a sealing airbag 1302, a micro air pump 1303, and an exhaust valve 1304. The installation cavity 1301 is opened on the side of the heat insulation partition 1204. The sealing airbag 1302 is installed inside the installation cavity 1301. A micro air pump 1303 is installed on one side of the sealing airbag 1302 on the installation cavity 1301. An exhaust valve 1304 is provided on one side of the sealing airbag 1302. Specifically, such as Figures 1 to 6As shown, when the user sets the dimensions of the two areas inside the display cabinet body 1 according to their needs, the control system drives the electric slide rail 1202 to operate, causing the slider 1203 in the slide groove 1201 to slide along the track, thereby driving the insulation partition 1204 below the slider 1203 to move synchronously. The position sensor 14 on one side of the insulation partition 1204 monitors the relative position of the insulation partition 1204 and the display cabinet body 1 in real time and feeds the data back to the control system. When the insulation partition 1204 moves to the preset position, the electric slide rail 1202 stops running to ensure that the dimensions of the two areas meet the set requirements. After the insulation partition 1204 reaches the designated position, the micro air pump 1303 is powered on and inflates the sealing airbag 1302 in the mounting cavity 1301. After the sealing airbag 1302 expands, it fits tightly against the inner wall of the display cabinet body 1, blocking the air convection between the two areas inside the display cabinet body 1 and avoiding temperature crosstalk. If the partition size needs to be adjusted, the control system first controls the exhaust valve 1304 to open, releasing the gas in the sealing airbag 1302. After the sealing airbag 1302 contracts, the electric slide rail 1202 drives the insulation partition 1204 to move again. The coordinated operation of the sliding component 12 and the sealing component 13 creates an independent and controllable storage environment for the two internal cavities of the display cabinet body 1 through the dual effect of "flexible space division + reliable temperature isolation", thereby precisely meeting the storage needs of people for different items. At the same time, the two sets of sealing doors 2 on the front of the display cabinet body 1 can be opened and closed independently, making it easy to take out and put in items in the two areas separately. The sealing strip 11 between adjacent sealing doors 2 ensures the overall sealing performance after the door is closed, reducing the intrusion of external hot air. Based on the real-time data of the temperature sensor 15, the control system dynamically adjusts the passage status of the dual-way solenoid valve 6, the number of opening and closing of the one-way solenoid valve 803, and even the operating frequency of the compressor 3, so that the temperature of the two areas is always stable within the set range, realizing the precise control of "dual temperature switching".
[0022] Two sets of sealing doors 2 are slidably installed on the front side of the display cabinet body 1. A sealing strip 11 is provided between two adjacent sets of sealing doors 2. A placement groove 101 is opened at the bottom of the display cabinet body 1. A compressor 3 is installed inside the placement groove 101. A condenser 4 is installed on one side of the compressor 3 through a pipe. An expansion valve 5 is installed on one side of the condenser 4 through a delivery pipe 7. A double-way solenoid valve 6 is installed on the expansion valve 5 through a pipe. An adjustment component 8 is provided on one side of the double-way solenoid valve 6. A capillary tube 9 is installed on the other end of the double-way solenoid valve 6. Pipe 2 9 is connected to one end of evaporator 10, and the other end of evaporator 10 is connected to compressor 3. Adjustment component 8 includes capillary tube 1 801, diverter tube 802 and one-way solenoid valve 803. Capillary tube 1 801 is connected to one end of double-way solenoid valve 6. Diverter tubes 802 are installed at equal intervals on the surface of capillary tube 1 801. One-way solenoid valves 803 are installed on each diverter tube 802. Evaporator 10 has an "S" shaped structure. The other end of diverter tube 802 is connected to the bend at the bottom of evaporator 10. Specifically, such as Figures 2 to 6As shown, during the operation of the device, the compressor 3 draws in the low-temperature, low-pressure refrigerant gas returning from the evaporator 10, compresses it into a high-temperature, high-pressure gaseous refrigerant, and transports it to the condenser 4 through a pipeline. In the condenser 4, the high-temperature, high-pressure gaseous refrigerant exchanges heat with the outside air and undergoes a condensation process, transforming into a medium-temperature, high-pressure liquid refrigerant, thus releasing heat. The medium-temperature, high-pressure liquid refrigerant enters the expansion valve 5 through the delivery pipe 7, and is throttled and depressurized through the valve port, transforming into a low-temperature, low-pressure gas-liquid mixture refrigerant, creating conditions for subsequent evaporation and heat absorption. After entering the evaporator 10, the low-temperature, low-pressure refrigerant absorbs heat from the internal air of the display cabinet body 1, undergoes an evaporation process, and transforms into a low-temperature, low-pressure gaseous refrigerant, thereby lowering the temperature inside the cabinet. Finally, the gaseous refrigerant returns to compressor 3, completing the entire refrigeration cycle. When dual-temperature adjustment is required, the temperature sensors 15 on both sides of the insulation partition 1204 monitor the actual temperatures of the two zones in real time and continuously transmit the data to the control system. The control system switches the refrigerant flow path through the dual-way solenoid valve 6 based on the difference between the target temperature and the actual temperature. If a certain area needs to maintain a higher temperature, the dual-way solenoid valve 6 switches to the capillary tube 9 passage, and the refrigerant directly enters the initial section of the evaporator 10 through the capillary tube 9. Due to the large inner diameter or short length of the capillary tube 9, the refrigerant flow rate is small, and it can only drive a part of the evaporator 10 to participate in heat exchange, resulting in weak cooling intensity. When valve 6 switches to the regulating component 8, the refrigerant first enters the capillary tube 801. The capillary tube 801 has a small inner diameter or a long length, which can initially throttle the refrigerant. Then, it is distributed to the evaporator 10 through the distribution pipe 802 on its surface. The evaporator 10 has an "S"-shaped structure, and multiple bends at its bottom are connected to the distribution pipe 802 of the regulating component 8 one by one. The control system controls the opening and closing of the corresponding distribution pipe 802 by opening different numbers of one-way solenoid valves 803. By controlling the number of one-way solenoid valves 803 and the path switching of the double-way solenoid valve 6, the refrigerant input and the heat exchange area of the evaporator 10 are precisely regulated, ultimately achieving dual-temperature stable control of "matching different cooling capacities to different volume areas".
[0023] In use, after the user sets the dimensions of the two cavities, the control system drives the electric slide rail 1202 to rotate, causing the slider 1203 and the insulation partition 1204 to slide along the slide groove 1201. The position sensor 14 provides real-time feedback on the position, ensuring that the insulation partition 1204 stops at the preset position. Subsequently, the micro air pump 1303 inflates the sealing airbag 1302, which adheres to the cabinet wall to block the convection between the two cavities. During adjustment, the exhaust valve 1304 releases air, allowing the insulation partition 1204 to slide again. During operation, the compressor 3 compresses the low-temperature, low-pressure refrigerant returning from the evaporator 10 into a high-temperature, high-pressure gaseous state, which is then cooled. The refrigerant condenses into a liquid state in condenser 4, then passes through expansion valve 5 to reduce its pressure into a gas-liquid mixture. After absorbing heat and cooling in evaporator 10, the refrigerant returns to compressor 3, completing the cycle. During operation, the real-time temperature is monitored by temperature sensors 15 on both sides of insulation partition 1204 and transmitted to the control system. The system switches paths via a two-way solenoid valve 6. When high temperature is required, it switches to capillary tube 2 9, where the refrigerant flow is low and heat exchange in evaporator 10 is localized. When low temperature is required, it switches to regulating component 8, where the refrigerant is throttled through capillary tube 1 801 and then distributed to evaporator 10 through distributor pipe 802. The control system adjusts the number of heat exchange sections in evaporator 10 by controlling the number of opening and closing of one-way solenoid valves 803, matching the cooling capacity of the two chambers.
