Description

Technical Field

[0001] This utility model relates to the field of agricultural product preservation technology, and in particular to a daylily preservation and storage device. Background Technology

[0002] Daylily, a nutritious and highly seasonal vegetable, has delicate buds with a high water content. After harvesting, its vigorous respiration makes it extremely prone to wilting and spoilage at room temperature, resulting in a very short shelf life. Therefore, to extend the supply period of daylilies and maintain their freshness, low-temperature refrigeration is usually required for preservation.

[0003] Currently, general-purpose refrigerated display cases or cold storage rooms are commonly used for preserving daylilies. However, these general-purpose devices are not designed specifically for the delicate characteristics of daylilies. Their internal cold air circulation is usually quite simple and direct, often resulting in uneven airflow distribution within the storage room. In some areas, the wind speed is too high, blowing directly onto the daylilies and causing excessive evaporation of surface moisture, leading to drying and discoloration. In other areas, poor airflow and ineffective cooling fail to effectively suppress the daylilies' respiration heat, resulting in localized overheating and accelerated spoilage.

[0004] Furthermore, due to the high water content and respiration of daylilies, a large amount of condensation is produced in low-temperature environments. In existing general-purpose equipment, this condensation typically adheres to the inner walls or top plate of the equipment and drips randomly. When this condensation drips onto the surface of the daylilies, it creates a locally high-humidity environment, which easily breeds mold and other microorganisms, leading to spoilage. Therefore, existing preservation equipment struggles to simultaneously address the two key issues of uniform cooling of daylilies and effective condensation management, resulting in unsatisfactory overall preservation effects and failing to fully meet the requirements for high-quality long-term storage of daylilies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a daylily preservation and storage device, which aims to improve the problems of uneven cooling of daylilies and poor condensate treatment in existing daylily preservation and storage devices, resulting in poor preservation effect. This utility model aims to provide a daylily preservation and storage device with an improved structure that can effectively solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a daylily preservation and storage device, comprising: a support assembly, the support assembly including a base, a side frame and a sealing cover; a holding bracket disposed within the support assembly; a heat preservation mechanism; and a collection mechanism.

[0007] The heat preservation mechanism includes a serpentine evaporator, a fan, and an air guide plate, with honeycomb holes formed on the air guide plate.

[0008] Furthermore, the heat preservation mechanism is located above the holding bracket, and the collection mechanism is located below the holding bracket. The collection mechanism includes an inclined guide plate and a water collection box. The inclined guide plate is located below the holding bracket to receive condensate flowing down from the inner wall of the side frame, and the water collection box is located below the inclined guide plate.

[0009] Preferably, the heat preservation mechanism further includes a sealed motor for driving the fan to rotate, and both the sealed motor and the fan are mounted on the lower surface of the sealing cover.

[0010] Preferably, the insulation mechanism further includes a sensor, which is fixed to the inner wall of the side frame.

[0011] Preferably, the upper surface of the inclined guide plate is provided with textures for guiding water flow.

[0012] Preferably, the collection mechanism further includes a hydrophobic plate, which is connected between the lower edge of the inclined guide plate and the water collection box.

[0013] Preferably, a filter screen is fixed at the water inlet of the water collection box that is connected to the hydrophobic plate.

[0014] Preferably, the outer walls of both sides of the water collection box are fixed with sliders, and the inner wall of the base is provided with a slide rail that slides with the sliders.

[0015] Preferably, a handle is fixed on the front end face of the water collection box.

[0016] This utility model has the following beneficial effects: In this invention, by setting an air guide plate below the fan and opening honeycomb holes on the air guide plate, the problem of local frost damage, drying or uneven cooling of daylilies caused by direct cold air blowing or turbulent airflow in the prior art is solved. This achieves the excellent technical effect of forming a uniform and stable air curtain of cold air, which can gently and thoroughly cool all daylilies, significantly improving the quality of preservation.

[0017] This invention solves the problems of condensate accumulation and dripping contamination of daylilies in existing preservation devices, as well as mold and rot caused by excessive humidity, by setting an inclined guide plate at the bottom of the side frame and a pull-out water collection box, along with a filter screen. It achieves the technical effect of efficiently separating and collecting condensate and impurities, maintaining a clean and moderately humid storage environment, and effectively extending the storage life of daylilies.

The support component 1 is equipped with a holding bracket 4, a heat preservation mechanism 3 and a collection mechanism 2. The support component 1 consists of a base 103, a side frame 101 fixed on the base 103 and a sealing cover plate 102 covering the upper end of the side frame 101. The base 103, the side frame 101 and the sealing cover plate 102 together form a closed space for preservation and storage. The holding bracket 4 is set in the space enclosed by the side frame 101 and is used to hold the daylilies to be preserved.

A fan 302 and an air guide plate 303 are fixedly connected above the holding bracket 4. The heat preservation mechanism 3 also includes a sealed motor 301 that drives the fan 302 to rotate. The sealed motor 301 and the fan 302 are both installed on the lower surface of the sealed cover plate 102. The air guide plate 303 is fixed below the fan 302. The air guide plate 303 has honeycomb holes 305 to even out the airflow generated by the fan 302 and blow it downward. The heat preservation mechanism 3 also includes a sensor 306 fixed on the inner wall of the side frame 101. Collection mechanism 2 is used to collect and drain the condensate generated inside the device. Please refer to [reference needed]. Figure 1 , Figure 3 and Figure 4 The collection mechanism 2 includes an inclined guide plate 201 located below the holding bracket 4 and a water collection box 204 located below the inclined guide plate 201. The upper surface of the inclined guide plate 201 is provided with textures for guiding water flow. The inclined guide plate 201 is used to receive condensate flowing down from the inner wall of the side bracket 101 and guide it to the water collection box 204. The collection mechanism 2 also includes a drainage plate 202, which is connected between the lower edge of the inclined guide plate 201 and the water collection box 204. A filter screen 206 is fixed at the water inlet of the water collection box 204 connected to the drainage plate 202. Slider blocks 203 are fixed on both outer walls of the water collection box 204. A slide rail is provided on the inner wall of the base 103 to slide with the slider 203. A handle 205 is fixed on the front end face of the water collection box 204. The water collection box 204 can be easily pulled out along the slide rail by using the handle 205.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3The sealing motor 301 and fan 302 of the insulation mechanism 3 are fixed to the lower surface of the sealing cover plate 102 by bolts. The serpentine evaporator 304 surrounds the outer periphery of the fan 302 and the air guide plate 303, and the serpentine evaporator 304 is fixed to the side of the side frame 101. The air guide plate 303 is fixedly connected to the lower part of the fan 302 by snap-fit ​​or screw connection. Multiple honeycomb holes 305 are densely and evenly distributed on the plate of the air guide plate 303. When the fan 302 rotates, the airflow is forced from top to bottom through the gap of the serpentine evaporator 304 for heat exchange and cooling. Then the cold airflow impacts... The air flows onto the air guide plate 303 and, under the rectification effect of the honeycomb holes 305, forms a uniform, vertically downward cold air curtain. This structure ensures that the cold air can cover the storage bracket 4 below without any dead angles, avoiding local overcooling or insufficient temperature. The sensor 306, fixed on the inner wall of the side frame 101, is connected to the control circuit of the serpentine evaporator 304 and the sealed motor 301. The function of the sensor 306 is to monitor the temperature in the storage space in real time and feed the temperature signal back to the control circuit, thereby realizing the automatic adjustment of the cooling power of the serpentine evaporator 304 and the speed of the fan 302.

[0024] Please refer to Figure 1 , Figure 3 and Figure 4 The inclined guide plate 201 is fixed to the lower inner wall of the side frame 101, and the plate surface of the inclined guide plate 201 is inclined downward from the side frame 101 towards the center of the device. The upper surface of the inclined guide plate 201 is processed with water guiding patterns extending along the inclined direction. This structural design ensures that the condensate collected from the inner wall of the side frame 101 can flow quickly to the lowest point of the inclined guide plate 201 under the action of gravity and guided by the patterns. The upper end of the drain plate 202 is fixedly connected to the lower edge of the inclined guide plate 201. The lower end of 202 extends into the inlet of the water collection box 204. Guided by the drainage plate 202, the water flow is precisely guided into the water collection box 204. The filter screen 206 fixed at the inlet of the water collection box 204 can effectively intercept daylily leaves or other impurities washed down by the water flow, keeping the inside of the water collection box 204 clean. The sliding fit structure formed by the sliders 203 on both sides of the water collection box 204 and the slide rails on the inner wall of the base 103 ensures that the water collection box 204 can be smoothly pulled out and pushed in.

The body of the sealing motor 301 is fixed to the lower surface of the sealing cover plate 102 by bolts. The sealing cover plate 102 forms an effective physical isolation and seal for the sealing motor 301 and the fan 302, preventing the high humidity environment in the storage space from damaging the motor.

[0026] As another preferred embodiment, in order to achieve precise monitoring of the internal environment of the device, please refer to... Figure 4 The sensor 306 of the insulation mechanism 3 is specifically an integrated temperature and humidity sensor 306. The sensor 306 is fixed to the middle of the inner wall of the side frame 101 by adhesive or screws. This position can represent the average temperature and humidity status in the storage space, thereby providing more accurate environmental parameters for the control system.

[0027] As a preferred embodiment, to further improve the flow efficiency of condensate, please refer to... Figure 3 The upper surface of the inclined guide plate 201 is processed with multiple parallel V-shaped grooves extending along the inclined direction. This V-shaped groove structure can gather scattered water droplets into a linear water flow, accelerate the water flow speed, and prevent water from accumulating and remaining on the surface of the guide plate.

[0028] As a preferred embodiment, to more smoothly guide the water flow from the inclined guide plate 201 into the water collection box 204, please refer to... Figure 3 The drainage plate 202 of the collection mechanism 2 is a water guide inclined plate with a certain curvature. The upper edge of the drainage plate 202 and the lower edge of the inclined guide plate 201 are connected by waterproof adhesive or clips. The lower edge of the drainage plate 202 naturally hangs into the water inlet of the water collection box 204, ensuring a smooth transition of water flow.

[0029] As a preferred embodiment, to improve filtration efficiency and facilitate cleaning, please refer to... Figure 3 The filter screen 206 is detachably installed on the inlet frame of the water collection box 204.

[0030] As a preferred embodiment, to facilitate the easy assembly and disassembly of the water collection box 204, please refer to... Figure 4 The inner wall of the base 103 is integrally formed or fixedly installed with a slide rail that matches the shape of the slider 203. The slider 203 and the slide rail are in clearance fit to ensure smooth pulling process. At the same time, a limiting protrusion can be set at the end of the slide rail to prevent the water collection box 204 from being accidentally pulled out completely.

[0031] As a preferred implementation method, to improve the ease of operation and feel, please refer to... Figure 3 The handle 205 is fixed to the center of the front end face of the water collection box 204 by screws. The handle 205 is designed to be an ergonomic arc or ring structure.

[0032] Working principle: First, place the daylilies to be stored on the holding rack 4 and start the device. The sealed motor 301 drives the fan 302 to rotate. At the same time, the serpentine evaporator 304 enters the refrigeration working state. The airflow generated by the fan 302 undergoes forced convection heat exchange through the serpentine evaporator 304 to form cold air. Under the rectification effect of the air guide plate 303 and its honeycomb holes 305, the cold air forms a uniform cold air that blows from top to bottom across the daylilies on the holding rack 4, quickly removing the field heat and respiration heat of the daylilies, and achieving efficient and uniform cooling. Secondly, during the cooling process, the moisture on the surface of the daylily and in the air will condense into water droplets on the inner wall of the side shelf 101, which is at a lower temperature. Under the action of gravity, the water droplets flow downward along the inner wall of the side shelf 101 and collect on the inclined guide plate 201 located below the holding bracket 4. The condensed water is further collected and flows to the drainage plate 202 under the guidance of the patterns on the inclined guide plate 201. Then, it is guided into the water collection box 204 at the bottom of the device through the drainage plate 202. When the water flows through the filter screen 206 at the inlet of the water collection box 204, impurities such as daylily leaves are effectively intercepted. Furthermore, the sensor 306 fixed to the inner wall of the side frame 101 monitors the temperature and humidity in the storage space in real time and feeds the signal back to the control system. The control system dynamically adjusts the cooling power of the serpentine evaporator 304 and the speed of the sealed motor 301 according to the preset value and the feedback signal from the sensor 306, thereby changing the wind speed of the fan 302. Through this closed-loop control method, the inside of the device is always kept in the most suitable low temperature and high humidity environment for the preservation of daylilies. Finally, when it is necessary to clean the water in the water collection box 204, the operator can hold the handle 205 and easily pull the water collection box 204 out of the base 103 by sliding the sliders 203 on both sides of the water collection box 204 with the slide rails on the inner wall of the base 103 for emptying and cleaning.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
