Description

Technical Field

[0001] This utility model relates to the field of medicine storage cabinet technology, and in particular to a dual-temperature zone medicine storage cabinet. Background Technology

[0002] With the continuous development of the pharmaceutical industry, the variety of medicines is increasing, and there are certain requirements for temperature and humidity during storage. Some medicines need to be stored in a cool environment, with the storage temperature controlled between 8-20 degrees Celsius, to extend their shelf life and prevent the efficacy from decreasing or deteriorating. A medicine storage cabinet is a specialized device for storing medicines, using refrigeration components to control the temperature and provide a suitable storage environment.

[0003] Medicine storage cabinets operate on a similar cooling principle to household air conditioners, allowing for relatively precise temperature control. However, because they rely on evaporators for cooling, the air temperature drops upon contact with the evaporator, reducing its water-holding capacity. This leads to condensation that adheres to the evaporator, increasing ambient humidity. When this condensation enters the cabinet, it causes excessive humidity around the medicines, resulting in moisture absorption. Therefore, effective dehumidification components are needed to control the internal humidity of the medicine storage cabinet and compensate for existing technological shortcomings. Furthermore, to differentiate between different types of medicines, different temperature zones should be rationally created to meet both cooling and cool storage requirements. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Reference Figures 1 to 5 One embodiment provided by this utility model:

[0024] A dual-temperature zone medicine storage cabinet includes a cabinet body 1 for storing medicines. The cabinet body 1 is characterized by having a spaced-apart cooling chamber 2 and a cool chamber 3 inside, a cooling component for cooling the interior of the cabinet body 1, and a dehumidifying component for dehumidifying the interior of the cabinet body 1. The cabinet body 1 has an openable door 4 on its front side and an air inlet 5 and an air outlet 6 on its rear side. The cooling component communicates with the interior of the cooling chamber 2 and the cool chamber 3 through the air inlet 5, and the dehumidifying component communicates with the interior of the cooling chamber 2 and the cool chamber 3 through the air outlet 6.

[0025] Cooling chamber 2 and cooling chamber 3 are located inside cabinet 1 and are spaced apart, either vertically or horizontally. Cabinet door 4 is located on the front of cabinet 1 and is openable, corresponding to the surfaces of cooling chamber 2 and cooling chamber 3. It can open from one side or both sides. Both cooling chamber 2 and cooling chamber 3 are connected to independently controlled cooling and dehumidifying components, allowing for separate and independent temperature and humidity control. The temperature range for cooling chamber 2 can be controlled between 2-8 degrees Celsius, and the temperature range for cooling chamber 3 between 8-20 degrees Celsius, meeting the storage requirements of different types of medicines.

[0026] Air inlets 5 and outlets 6 are located on the rear side of cabinet 1. Cooling chamber 2 and cooling chamber 3 each have a set of air inlets 5 and outlets 6. The cooling system is connected to the interior of cooling chamber 2 and cooling chamber 3 through air inlets 5. When the cooling system is activated, outside air is cooled by the cooling system and enters the interior of cooling chamber 2 and cooling chamber 3 through the vents, thereby controlling the storage environment temperature. The dehumidification system is connected to the interior of cooling chamber 2 and cooling chamber 3 through outlets 6. When the dehumidification system is activated, air from inside cooling chamber 2 and cooling chamber 3 enters the dehumidification system through outlets 6 and is dehumidified, thereby controlling the storage environment humidity.

[0027] This utility model is equipped with a refrigeration component and a dehumidification component, which separately control the temperature and humidity of the refrigeration chamber 2 and the cool chamber 3 without interfering with each other, thereby realizing the dual temperature zone regulation function. By adjusting to different temperatures and humidity, it can adapt to different types of medicines, overcoming the problems in the prior art where medicine storage cabinets lack dehumidification function, causing medicines to be easily damp, and the storage temperature zone is singular, unable to take into account both refrigeration and cool storage environments.

[0028] In this embodiment, preferably, the refrigeration assembly includes a compressor 7, a condenser 8 and an evaporator 9 respectively connected to the compressor 7, and a filter 10 and a capillary tube 11 connected between the condenser 8 and the evaporator 9. The evaporator 9 is located outside the air inlet 5, and a refrigeration fan 12 is provided between it and the air inlet 5.

[0029] The compressor 7 is connected to the condenser 8 and evaporator 9. The filter 10 and capillary tube 11 are located between the condenser 8 and evaporator 9, and can be connected sequentially as follows: evaporator 9, capillary tube 11, filter 10, and condenser 8. The evaporator 9 is located outside the air inlet 5, and the refrigeration fan 12 is located between the evaporator 9 and the air inlet 5, with the fan blowing air towards the air inlet 5. The evaporator 9 absorbs heat through the evaporation of liquid refrigerant, lowering the ambient temperature. The condenser 8 releases heat through the condensation of gaseous refrigerant, dissipating the heat into the surrounding environment. The evaporator 9 serves as the refrigeration component. The refrigeration fan 12 corresponds to the air inlet 5. After the refrigeration components are started, the temperature of the air outside the evaporator 9 decreases, and the air is drawn in by the refrigeration fan 12 and blown into the refrigeration chamber 2 and the cooling chamber 3 through the air inlet 5, thus achieving the refrigeration function.

[0030] In this embodiment, preferably, the dehumidification component includes a cooling semiconductor 14, which is located outside the air outlet 6 and is provided with a dehumidification fan 15 between it and the air outlet 6. A drain pipe communicating with the outside is provided below the cooling semiconductor 14.

[0031] The cooling semiconductor 14 is located outside the air outlet 6, and the dehumidifying fan 15 is located between the cooling semiconductor 14 and the air outlet 6, with the airflow direction of the dehumidifying fan 15 facing the cooling semiconductor 14. A drain pipe is located below the cooling semiconductor 14 and connects to the outside, allowing water remaining on the surface of the cooling semiconductor 14 to flow into the drain pipe and be discharged to the outside. The cooling semiconductor 14 achieves cooling based on the Peltier effect in thermoelectric effects, through energy transfer generated by direct current in N-type and P-type semiconductor materials. When the temperature is lower than the dew point temperature of the air, moisture in the air condenses into water droplets, thereby reducing the humidity of the air and achieving a dehumidification effect. The dehumidifying fan 15 corresponds to the air outlet 6. After the dehumidification component is activated, the surface temperature of the cooling semiconductor 14 decreases, and the air inside the cooling chamber 2 and the cool chamber 3 is drawn by the dehumidifying fan 15 and blown from the air outlet 6 onto the surface of the cooling semiconductor 14. After the air cools down, water droplets condense on the surface of the cooling semiconductor 14 and flow into the drain pipe below, thus being discharged to the outside.

[0032] In this embodiment, preferably, the refrigeration component and the dehumidification component are connected to a microcontroller, and both the refrigeration chamber 2 and the cooling chamber 3 are equipped with a temperature sensing module and a humidity sensing module connected to the microcontroller.

[0033] Both the cooling chamber 2 and the cooling chamber 3 are equipped with temperature and humidity sensors. The temperature sensor detects temperature information, and the humidity sensor detects humidity information. A microcontroller is connected to both the temperature sensor and the cooling components. The temperature sensor feeds back the temperature information from the cooling chamber 2 and cooling chamber 3 to the microcontroller, which then controls the cooling components to achieve temperature regulation. Similarly, the microcontroller is connected to both the humidity sensor and the dehumidification components. The humidity sensor feeds back the humidity information from the cooling chamber 2 and cooling chamber 3 to the microcontroller, which then controls the dehumidification components to achieve humidity regulation.

[0034] In this embodiment, preferably, the microcontroller is provided with a cooling temperature sensing threshold corresponding to the temperature sensing module of the cooling chamber 2 and a cooling temperature sensing threshold corresponding to the temperature sensing module of the cooling chamber 3. The cooling temperature sensing threshold is set to 2-8 degrees Celsius and the cooling temperature sensing threshold is set to 8-20 degrees Celsius.

[0035] The microcontroller sets separate cooling temperature sensing thresholds and cooling temperature sensing thresholds to limit the temperature range of cooling chamber 2 and cooling chamber 3. The cooling temperature sensing threshold corresponds to the temperature sensing module of cooling chamber 2 and is set to 2-8 degrees Celsius, which meets the requirements for the refrigerated storage environment of pharmaceuticals. The cooling temperature sensing threshold corresponds to the temperature sensing module of cooling chamber 3 and is set to 8-20 degrees Celsius, which meets the requirements for the cool storage environment of pharmaceuticals.

[0036] In this embodiment, preferably, the refrigeration assembly is provided with a four-way reversing valve 13 connected to a microcontroller. One side of the four-way reversing valve 13 is connected to the exhaust end of the compressor 7, and the other side of the four-way reversing valve 13 is connected to the suction end of the compressor 7, the condenser 8 and the evaporator 9 respectively.

[0037] The four-way reversing valve 13 is located between the compressor 7 and the condenser 8 and evaporator 9. It acts as a controllable switch to switch between the refrigeration circuit and the defrosting circuit of the refrigeration assembly. One side of the four-way reversing valve 13 is connected to the discharge end of the compressor 7, and the other side is connected to the suction end of the compressor 7, the condenser 8, and the evaporator 9. The suction end of the compressor 7 corresponds to the middle position of the four-way reversing valve 13. The condenser 8 and evaporator 9 are located on either side of the suction end of the compressor 7. The refrigeration circuit realizes the refrigeration function of the refrigeration assembly. It is formed by sequentially connecting the discharge end of the compressor 7, the four-way reversing valve 13, the condenser 8, the filter 10, the capillary tube 11, the evaporator 9, the four-way reversing valve 13, and the suction end of the compressor 7, thereby lowering the temperature of the air outside the evaporator 9. The defrosting circuit enables the defrosting function of the refrigeration components. It consists of the compressor 7 discharge end, four-way reversing valve 13, evaporator 9, capillary tube 11, filter 10, condenser 8, four-way reversing valve 13, and compressor 7 suction end connected in sequence to form a circuit, thereby eliminating the frost condensed on the surface of evaporator 9.

The switch module can switch the power supply mode. The microcontroller is connected to the switch module and the communication module. The communication module is connected to a mobile phone signal, allowing operation commands to be sent to the communication module via a mobile app or WeChat mini-program.

[0040] In this embodiment, preferably, the cabinet 1 is equipped with a power module and a charging power supply. The power module is connected to the microcontroller and the battery, and the charging power supply is connected to the battery and the microcontroller.

[0041] The power module and charging power supply are located inside cabinet 1. The power module is connected to the microcontroller and the battery. It detects the battery's power level and sends the information back to the microcontroller. The charging power supply is connected to the battery and the microcontroller. The charging power supply has a switch function. The microcontroller compares the current power level with a preset power level. If the current power level is lower than the preset level, the microcontroller controls the charging power supply to turn on and charge the battery.
