Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a water-spraying structure and a portable air conditioner containing the same. Background Technology

[0002] Currently, most portable air conditioners use vertically arranged fan blades for water dispensing, employing a vertical water dispensing method. However, because the condenser is often vertically positioned, vertical dispensing causes some of the dispensed water to be thrown vertically out at the edge of the fan blades instead of reaching the condenser on either side. This results in low condensate utilization and low dispensing efficiency. Furthermore, the evaporator is mounted on a drip tray, while the condenser and dispensing motor are mounted on the chassis. The water condensed on the evaporator drips into the drip tray and then falls onto the chassis through the drain holes. Once the chassis is filled with water, the dispensing motor starts dispensing water, which is slow. The time from machine operation to dispensing water is considerable, impacting cooling efficiency and user experience.

[0003] To address the above issues, existing technology discloses a control method for a water pumping motor. Although the water level is controlled by adjusting the speed of the blower and the water pumping motor, this method does not improve the problems of low vertical water pumping efficiency and slow water storage. Utility Model Content

[0004] The purpose of this utility model is to provide a water-feeding structure and a portable air conditioner containing the same, so as to solve the technical problems of unreasonable water-feeding structure, low water-feeding efficiency and slow water storage in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a water-spraying structure, including a base, a water-spraying motor, and at least one layer of water-spraying fan blades; wherein: The water pump motor is arranged vertically with its rotation axis pointing upwards; At least one layer of the water-pumping fan blades is horizontally arranged and sequentially installed on the rotating shaft of the water-pumping motor; The upper water-spraying fan blade is provided with a flow hole for condensate to flow to the lower layer.

[0006] By setting the water-pumping fan blades horizontally and installing them sequentially on the rotating shaft of the water-pumping motor, with a gap between adjacent layers of water-pumping fan blades, a uniform water-pumping effect can be achieved, improving water-pumping efficiency. Furthermore, due to the horizontal arrangement of the water-pumping fan blades, water can be stored quickly.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] As a further improvement of this utility model, the water-dispensing fan blade is a bowl-shaped blade that is smaller at the bottom and larger at the top, and the upper water-dispensing fan blade is provided with a number of water-spraying holes. The water-spraying holes are evenly distributed along the circumference of the water-dispensing fan blade, so that the condensed water can drip evenly onto the lower water-dispensing fan blade, thereby further improving the water breaking effect and evaporation efficiency.

[0009] As a further improvement of this utility model, the shapes of the water-discharging fan blades in all layers may be the same or different; and / or, the diameters of the water-discharging fan blades in all layers may be the same or different. By setting water-discharging fan blades of different shapes or diameters, the degree of water flow agitation and distribution range can be adjusted according to actual usage needs, thereby achieving a more efficient evaporation effect. In addition, the water-discharging fan blades are made of high-strength, corrosion-resistant engineering plastics, ensuring that they are not easily deformed or damaged during long-term use, thus improving the durability and reliability of the overall device.

[0010] As a further improvement of this utility model, the water-dispensing motor is a brushless DC motor with speed regulation function, which can automatically adjust the speed according to the ambient temperature and humidity, thereby realizing intelligent control of evaporation efficiency. In addition, the water-dispensing structure is also equipped with a water level sensor to monitor the water level in the water-dispensing fan blades in real time. When the water level is too high or too low, an alarm is issued to remind the user to adjust it in time.

[0011] As a further improvement of this utility model, the water-throwing holes are arranged in multiple groups, and all groups of water-throwing holes are evenly arranged along the entire inclined surface of the water-spraying fan blades. This ensures that the condensate can be evenly thrown out during rotation, and that some water droplets drip down to the lower fan blades under the action of gravity.

[0012] As a further improvement of this utility model, each group of water-throwing holes includes at least one water-throwing hole, and all the water-throwing holes in the same group are evenly arranged along the height direction of the water-discharging fan blades to further improve the uniformity and flowability of condensate distribution. In addition, the edges of the water-throwing holes are designed with an arc transition to reduce water flow resistance, prevent water droplet retention, and enhance overall operating efficiency. Condensate located within the water-discharging fan blades is partially thrown out through the fan blade edges and partially thrown out through the water-throwing holes, forming a multi-layered water droplet distribution, further improving evaporation efficiency. By rationally designing the position and number of water-throwing holes, the throwing angle and range of water droplets can be effectively controlled, making the water droplets more evenly distributed in the evaporation area, thereby optimizing overall performance.

[0013] As a further improvement of this utility model, the water-throwing hole at the lowest point is located near the bottom of the water-dispensing fan blade. This structural arrangement allows the water flow from the water-dispensing fan blade to cover a wider area, thereby reducing the number of layers of water-dispensing fan blades.

[0014] As a further improvement of this invention, the water-throwing hole is circular, rectangular, or elliptical. The shape of the water-throwing hole can be flexibly selected according to the actual water flow characteristics and the fan blade structure to ensure smooth water discharge during rotation, reducing resistance and improving drainage efficiency. Simultaneously, different shapes of water-throwing holes can be optimized for different operating conditions, thereby achieving precise control of water flow distribution. Furthermore, the inner wall of the water-throwing hole is provided with a smooth coating to further reduce water adhesion, prevent scale buildup, and extend the device's service life. Through the above structural optimizations, this invention can achieve efficient evaporation and uniform distribution of condensate, significantly improving overall operating efficiency and stability.

[0015] As a further improvement of this utility model, the flow holes are evenly arranged around the bottom of the water-spraying fan blade, and the size of the flow holes is not larger than the size of the water-spinning holes.

[0016] As a further improvement of this utility model, a closable sealing plate is provided at the flow hole. By providing this closable sealing plate, the opening and closing of the flow hole can be flexibly controlled according to actual operating conditions, thereby adjusting the water flow path and flow rate inside the water pump blades. During the initial startup phase or low-load operation, closing part of the sealing plate reduces the water circulation volume. During high-load operation, opening the sealing plate increases the water flow, ensuring timely discharge of condensate and even distribution for condenser cooling. This design not only improves the adaptability and adjustment flexibility of the device but also further optimizes overall operating efficiency and stability.

[0017] As a further improvement of this utility model, the sealing plate is installed inside the flow hole by a spring. One end of the spring is fixed to the inner wall of the flow hole, and the other end of the spring is fixed to the sealing plate. When there is no water in the water-discharging fan, the sealing plate blocks the bottom of the flow hole under the action of the spring. When there is a large amount of condensate in the water-discharging fan, the sealing plate is pushed away from the bottom of the flow hole, thereby opening the flow hole. Through this automatic opening and closing structure design, intelligent control of the flow hole can be achieved, effectively matching the drainage needs under different working conditions, and further improving the condensate treatment efficiency and system stability.

[0018] The present invention provides a portable air conditioner, including a condenser and a water pumping structure disposed next to the condenser.

[0019] The aforementioned water-pumping structure effectively collects and evaporates the condensate generated on the condenser surface. The compact and coordinated layout of this water-pumping structure and the condenser not only improves space utilization but also significantly enhances condensate treatment efficiency. Furthermore, the entire system features intelligent linkage control, which adjusts the operating status in real time based on condensate generation and ambient temperature and humidity, achieving energy-saving, environmentally friendly, and highly efficient and stable operation.

[0020] As a further improvement of this utility model, the portable air conditioner also includes an evaporator, a water tray assembly, and a chassis; wherein: The water receiving tray assembly is provided at the bottom of the evaporator; The water-spraying structure is located inside the chassis and is positioned directly opposite the water receiving tray assembly.

[0021] This design allows condensate collected by the drip tray assembly to drip directly onto the water-discharging structure. The rotating action then breaks up the water flow and accelerates its ejection onto the condenser, thus cooling it. This structural design not only achieves efficient condensate treatment but also effectively reduces water residue buildup inside the air conditioner, lowering the risk of mold growth.

[0022] As a further improvement of this utility model, the water receiving tray assembly is provided with a water outlet hole; the water pumping structure is located directly below the water outlet hole.

[0023] The condensate falls vertically through the outlet hole to the central area of ​​the water-spraying structure. The centrifugal force generated by the high-speed rotation of the water-spraying fan blades quickly throws the water droplets to the edge, thereby achieving uniform distribution and efficient breakup of the condensate.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-7 As shown, this utility model provides a water-spraying structure 14, including a water-spraying motor 141 and at least one layer of water-spraying fan blades 142; wherein: The water pumping motor 141 is arranged vertically, with the rotating shaft 143 facing upwards; At least one layer of the water-pumping fan blades 142 are horizontally arranged and sequentially installed on the rotating shaft 143 of the water-pumping motor 141; The upper-layer water-dispensing fan blades 142 are provided with flow holes for condensate to flow to the lower layer. It should be noted that the upper-layer water-dispensing fan blades 142 refer to all the water-dispensing fan blades 142 except for the bottommost one. The flow holes allow the condensate on the upper-layer fan blades to drip downwards, thereby ensuring that there is condensate in all the water-dispensing fan blades 142 for water dispensing.

[0029] By setting the water-pumping fan blades 142 horizontally and installing them sequentially on the rotating shaft 143 of the water-pumping motor 141, with a gap between adjacent layers of the water-pumping fan blades 142, a uniform water-pumping effect can be achieved, improving water-pumping efficiency. Furthermore, due to the horizontal arrangement of the water-pumping fan blades 142, water can be stored quickly.

[0030] It should be noted that in this embodiment, there is no limitation on the number of layers and height of the water-discharging fan blades 142. The specific number can be determined based on the actual condensation rate. For example, if there is little condensation, the first layer of water-discharging fan blades 142 is sufficient. If there is a lot of condensation, multiple layers can be designed according to the actual situation. There is also no limitation on the height difference. Water is ejected from the surrounding water-discharging holes 144. Some water falls through the water-discharging holes 144 to the next layer of water-discharging fan blades 142, while some flows out through the bottom flow holes.

[0031] As a further improvement of this utility model, the water-discharging fan blade 142 is a bowl-shaped blade with a smaller bottom and a larger top, and each layer of the water-discharging fan blade 142 is provided with a plurality of water-throwing holes 144. The water-throwing holes 144 are evenly distributed along the circumference of the water-discharging fan blade 142, so that the condensed water can be evenly thrown out onto the condenser 13, thereby further improving the water breaking effect and evaporation efficiency.

[0032] As a further improvement of this utility model, the water-discharging fan blades 142 in all layers may have the same or different shapes; and / or, the diameters of the water-discharging fan blades 142 in all layers may be the same or different. By setting water-discharging fan blades 142 with different shapes or diameters, the degree of water flow agitation and distribution range can be adjusted according to actual usage needs, thereby achieving a more efficient evaporation effect. In addition, the water-discharging fan blades 142 are made of high-strength, corrosion-resistant engineering plastics, ensuring that they are not easily deformed or damaged during long-term use, thus improving the durability and reliability of the overall device.

[0033] As a further improvement of this utility model, the water-dispensing motor 141 is a brushless DC motor with speed regulation function, which can automatically adjust the speed according to the ambient temperature and humidity, thereby realizing intelligent control of evaporation efficiency. In addition, the water-dispensing structure 14 is also equipped with a water level sensor to monitor the water level in the water-dispensing fan blade 142 in real time. When the water level is too high or too low, an alarm is issued to remind the user to adjust it in time.

[0034] As a further improvement of this utility model, the water-throwing holes 144 are arranged in multiple groups, and all groups of water-throwing holes 144 are evenly arranged along the entire inclined surface of the water-spraying fan blade 142. This ensures that the condensate can be evenly thrown out during rotation, and that some water droplets drip down to the lower fan blades under the action of gravity.

[0035] As a further improvement of this utility model, each group of water-throwing holes 144 includes at least one water-throwing hole 144, and all the water-throwing holes 144 in the same group are evenly arranged along the height direction of the water-discharging fan blade 142. This further improves the uniformity and flowability of condensate distribution. In addition, the edges of the water-throwing holes 144 are designed with arc transitions to reduce water flow resistance, avoid water droplet retention, and enhance overall operating efficiency. Part of the condensate located within the water-discharging fan blade 142 is thrown out through the edge of the fan blade, and part is thrown out through the water-throwing holes 144, forming a multi-layered water droplet distribution, further improving evaporation efficiency. By rationally designing the position and number of water-throwing holes 144, the throwing angle and range of water droplets can be effectively controlled, making the water droplets more evenly distributed in the evaporation area, thereby optimizing overall performance.

[0036] As a further improvement of this utility model, the water-throwing hole 144 located at the lowest point is positioned close to the bottom of the water-spraying fan blade 142. This structural arrangement allows the water flow from the water-spraying fan blade 142 to cover a wider area, thereby reducing the number of layers required for the water-spraying fan blade 142.

[0037] As a further improvement of this utility model, the water-throwing hole 144 is circular, rectangular, or elliptical. The shape design of the water-throwing hole 144 can be flexibly selected according to the actual water flow characteristics and the fan blade structure to ensure that the water can be smoothly discharged during rotation, reducing resistance and improving drainage efficiency. At the same time, different shapes of water-throwing holes 144 can be optimized for different operating conditions, thereby achieving precise control of water flow distribution. Furthermore, the inner wall of the water-throwing hole 144 is provided with a smooth coating to further reduce water adhesion, prevent scale buildup, and extend the service life of the device. Through the above structural optimizations, this utility model can achieve efficient evaporation and uniform distribution of condensate, significantly improving overall operating efficiency and stability.

[0038] As a further improvement of this utility model, the flow holes are evenly arranged around the bottom of the water-spraying fan blade 142, and the size of the flow holes is no larger than the size of the water-spinning hole 144. This structural arrangement ensures that most of the water is preferentially discharged through the water-spinning hole 144, while the flow holes are mainly used to allow condensate in the upper water-spraying fan blade 142 to drip down into the lower water-spraying fan blade 142, creating a multi-layer water-spraying effect and expanding the water-spraying range.

[0039] It should be noted that the flow orifice can be kept open, and the dripping speed can be adjusted by setting its diameter.

[0040] As a further improvement of this utility model, a closable sealing plate is provided at the flow hole. By providing this closable sealing plate, the opening and closing of the flow hole can be flexibly controlled according to actual operating conditions, thereby adjusting the water flow path and flow rate inside the water pump 142. During the initial startup of the equipment or under low load operation, closing part of the sealing plate can reduce the water circulation volume. Under high load operation, opening the sealing plate increases the water flow, ensuring that condensate is discharged promptly and evenly distributed for cooling the condenser 13. This design not only improves the adaptability and adjustment flexibility of the device but also further optimizes the overall operating efficiency and stability.

[0041] As a further improvement of this utility model, the sealing plate is installed inside the flow hole by a spring. One end of the spring is fixed to the inner wall of the flow hole, and the other end of the spring is fixed to the sealing plate. When there is no water in the water-discharging fan 142, the sealing plate blocks the bottom of the flow hole under the action of the spring. When there is a large amount of condensate in the water-discharging fan 142, the sealing plate is pushed away from the bottom of the flow hole, thereby opening the flow hole. Through this automatic opening and closing structure design, intelligent control of the flow hole can be realized, effectively matching the drainage needs under different working conditions, and further improving the condensate treatment efficiency and system stability.

[0042] In this embodiment, the sealing plate automatically opens and closes based on the amount of condensate accumulated within the water-discharging fan 142. When the accumulated amount is large, and its weight exceeds the spring force, the sealing plate is pushed downwards, opening the flow hole and allowing water to drain. Conversely, when the water volume decreases, the spring automatically resets, closing the sealing plate and maintaining a stable water flow within the water-discharging fan 142. This structure enables adaptive adjustment of the flow hole under different operating conditions, improving the intelligence level of the drainage system while reducing the frequency of manual intervention, thus enhancing the reliability and energy efficiency of the equipment.

[0043] Of course, the opening and closing of the sealing plate can also be controlled by a switch valve. A water level sensor detects the water level, thereby controlling the opening or closing of the switch valve, as well as the opening size. The switch valve control structure and the method of controlling the valve based on the water level are existing technologies and can be implemented using existing switch valves and switching logic. Further details will not be elaborated here.

[0044] In existing portable air conditioners, the water-discharging fan blades 142 are often vertically arranged, making it difficult for the water to effectively reach the condensers 13 on both sides. Furthermore, the water-discharging motor 141 is located on the chassis 15, resulting in slow water storage and a long time required from machine startup to water discharging. Therefore, this invention provides a portable air conditioner with horizontally arranged water-discharging fan blades 142, including a condenser 13 and a water-discharging structure 14 disposed beside the condenser 13. The water-discharging structure 14 is located inside the condenser 13, surrounded by the fins of the condenser 13. The frustum-shaped water-discharging fan blades 142 rotate horizontally, throwing condensed water through the water-throwing holes 144 onto the surrounding condenser 13 fins.

[0045] The water-dispensing structure 14 includes a water-dispensing motor 141 and at least one layer of water-dispensing fan blades 142. Each layer of water-dispensing fan blades 142 is bowl-shaped or frustum-shaped. The water condensed in the evaporator 11 enters directly into this frustum-shaped water-dispensing fan blade 142 through the water outlet 121 of the water receiving pan component 12, and then is sprayed to the periphery of the condenser 13 through horizontal rotation. Compared with the traditional method where condensate falls to the bottom of the pan 15 and reaches a certain depth before water is dispensed, the frustum-shaped design of the water-dispensing fan blades 142 helps to quickly receive and store condensate, solving the problem that the fan blades of ordinary water-dispensing motors 141 cannot effectively deliver water to the condenser 13. In addition, the time from start-up to the start of water dispensing is short, which speeds up the heat dissipation of the prototype, especially avoiding frequent protection shutdowns of the prototype under harsh operating conditions, thereby improving the user experience.

[0046] The water-pumping structure 14 effectively collects and evaporates the condensate generated on the surface of the condenser 13. The compact and coordinated layout between the water-pumping structure 14 and the condenser 13 not only improves space utilization but also significantly enhances the condensate treatment efficiency. Furthermore, the entire system features intelligent linkage control, which can adjust the operating status in real time according to the condensate generation and ambient temperature and humidity, achieving energy-saving, environmentally friendly, and highly efficient and stable operation.

[0047] As a further improvement of this utility model, the portable air conditioner also includes an evaporator 11, a water tray assembly, and a chassis 15; wherein: The water receiving tray assembly is provided at the bottom of the evaporator 11; The water-spraying structure 14 is disposed within the chassis 15 and is positioned directly opposite the water receiving tray assembly.

[0048] This design allows condensate collected by the drip tray assembly to drip directly onto the water jetting structure 14, where the rotation breaks up the water flow and accelerates evaporation. This structural design not only achieves efficient condensate treatment but also effectively reduces residual water inside the air conditioner, lowering the risk of mold growth.

[0049] As a further improvement of this utility model, the water receiving tray assembly is provided with a water outlet 121; the water pumping structure 14 is located directly below the water outlet 121. The water outlet 121 is located inside the water receiving tray assembly 12, and the water condensed by the evaporator 11 falls vertically from top to bottom onto the water pumping fan blade 142 through the water outlet 121.

[0050] After the prototype is running, the water condensed in the evaporator 11 falls onto the water receiving tray component 12. The condensate falls vertically through the water outlet 121 to the central area of ​​the water spraying structure 14. The centrifugal force generated by the high-speed rotation of the water spraying fan blades 142 quickly throws the water droplets to the edge, thereby achieving uniform distribution and efficient breaking of the condensate.

[0051] In this embodiment, the water-dispensing structure 14 inside the portable air conditioner includes an upper water-dispensing fan blade 142, a lower water-dispensing fan blade 142, and a water-dispensing motor 141; the upper and lower water-dispensing fan blades 142 are spaced apart on the rotating shaft 143 of the water-dispensing motor 141. During the water storage and dispensing process of the upper water-dispensing fan blade 142, the lower water-dispensing fan blade 142 can catch a small portion of the water falling from the upper water-dispensing fan blade 142.

[0052] like Figure 9 As shown, the control system of the portable air conditioner provided by this utility model consists of a data acquisition unit, a computing unit, and a control unit.

[0053] According to the centrifugal force formula Where n is the rotational speed of the water pump blade 142, and R is the radius of the position of the water pump blade 142 where the condensate is located. Therefore, according to the decomposition of centrifugal force and gravity, when the water pump blade 142 rotates at a certain speed, the condensate can reach a certain height on the water pump blade 142. The condensate is then thrown from the water-throwing hole 144 of the water pump blade 142 onto the surrounding condenser 13. The higher the rotational speed, the greater the height, and the higher the water outlet height. In this embodiment, taking the setting of two layers (two heights) of the water-spraying holes 144 as an example, when the water-spraying fan blade 142 rotates at a lower speed v1, the condensate can only pass through the lower water-spraying hole 144 and then be sprayed onto the surrounding condenser 13; when the fan blade rotates at a higher speed v2, the condensate can not only pass through the lower water-spraying hole 144, but also reach the upper water-spraying hole 144. That is, the higher the speed, the more water the condensate can reach through the water-spraying holes 144, and thus more water is sprayed onto the condenser 13. Moreover, the heat dissipation area is wider, which helps the system dissipate heat faster, improves the machine's overload performance and user experience, not only avoids frequent shutdown protection due to overheating, but also reduces the probability of water full protection.

[0054] like Figure 8 As shown, the water dispensing control method for the portable air conditioner of this utility model includes the following steps: When the prototype is turned on, first check the ambient humidity (RH), ambient temperature (Th), and condenser 13 temperature (Tn). First determine whether the ambient humidity (RH) is ≤ preset value A (preferably 70~90%).

[0055] If not, it indicates that the ambient humidity is high, requiring a higher rotation speed to pump water. The condensate can exit from the lower and upper water-spraying holes 144 and be pumped onto the condenser 13 for evaporation, avoiding or delaying the water full protection that is prone to occur in high humidity environments. In this case, the machine runs for t2 hours and then pumps water at a speed of V2. If yes, then it is necessary to determine whether the ambient temperature Th is ≤ T1 (preferably 35~37℃).

[0056] If not, it indicates that the ambient temperature is too high. If the temperature is too high, it will trigger the machine's overload protection, affecting the user experience. Therefore, the water pump motor 141 needs to pump water at a high speed v2 to increase the area of ​​condensate reaching the condenser 13 and accelerate the heat dissipation of the condenser 13. If yes, then continue to determine whether the temperature Tn of the condenser 13 is ≤ T2 (preferably 60~65℃).

[0057] If not, it means that although the ambient temperature and humidity are not high, the temperature of the condenser 13 is high due to some reasons, such as the air inlet of the condenser 13 being blocked or the air duct being blocked. In this case, in order to avoid the condenser 13 temperature being too high and causing the machine to frequently protect itself or even reach the safe temperature, the water pump motor 141 needs to pump water at a higher speed v2 to speed up the condensate to reach the condenser 13 for heat dissipation.

[0058] If so, it means that the ambient humidity, temperature, and condensation temperature are not high, the machine does not store water quickly, the operating conditions are not harsh, and a slower water dispensing speed is sufficient; in this case, the machine will dispensing water at speed v1 after running for t1 time.

[0059] Regarding t1 and t2, besides preventing the water pump motor 141 from running idle (because the machine doesn't have enough condensate when it's first turned on) and saving energy, t1 and t2 are also used to: if RH is greater than A, it indicates high humidity, and t2 should be preset to a shorter time (preferably 10-15 minutes) before water pumping can begin. Alternatively, if the condensing temperature Tn and ambient temperature Th are high, water pumping should begin as soon as possible, and t2 should be run after startup. Conversely, if the humidity, condensing temperature, and ambient temperature Th are not high, water pumping can begin after running for the duration of t1 (preferably 10-15 minutes).

[0060] Where: RH is ambient humidity, Th is ambient temperature, Tn is condenser 13 temperature, A is the preset relative humidity point (preferably 70~90%), T1 is the preset ambient temperature point (preferably 35~37℃), T2 is the preset condenser 13 temperature point (preferably 60~65℃), v1 and v2 are the two speeds of the water pump motor 141, v1 is a lower speed and v2 is a higher speed, and different speeds correspond to different maximum water outlet heights of the fan blades. t1 and t2 are the running time of the machine from power-on to the start of the water pump motor 141, t1 is longer and t2 is shorter (t1 is preferably 10~15min, t2 is preferably 5~10min).

[0061] First, it should be noted that "inward" refers to the direction towards the center of the storage space, while "outward" refers to the direction away from the center of the storage space.

[0062] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
