Description

Technical Field

[0001] The present invention relates to the technical field of cabinets, and more particularly to an integral cabinet capable of preventing moisture and sterilizing. Background Art

[0002] Integral cabinets are generally used in places such as kitchens. They generally include an integral cabinet body and cabinet doors. Multiple horizontal cabinet panels are installed in the inner cavity of the cabinet body, and the cabinet panels divide the cabinet body into a multi-layer structure. Each layer holds different items. However, due to the characteristics of integral cabinets used in kitchens, the environment in which they are located is relatively humid. During long-term use, water vapor can easily penetrate from the outer wall of the cabinet door into the cabinet panels. In the process of water vapor components penetrating into the cabinet body, the inner wall of the cabinet body is prone to mold and produce bacteria due to moisture, affecting the subsequent use of the cabinet.

[0003] In the related technical solution, in order to realize moisture-proof and sterilization of the cabinet, a dehumidification fan is installed on the upper part of the cabinet, and the air outlet of the fan extends from the upper wall of the cabinet to the inner cavity of the cabinet.

[0004] However, in the above technical solution, the airflow formed by the fan forms turbulence in the cabinet, and the airflow penetrates from the gap between the cabinet door and the cabinet body, and then is discharged from the fan. This setting method causes the airflow to form turbulence in the entire cabinet body. In order to achieve drying and sterilization of the entire inner wall of the cabinet, the fan needs to provide a large suction force and a long exhaust and dehumidification treatment time. Summary of the invention

[0005] The purpose of the present invention is to overcome or at least alleviate the deficiencies of the above-mentioned prior art, so as to solve at least one of the above-mentioned technical problems.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a moisture-proof and sterilizing integrated cabinet, including a cabinet body, an inner cavity in the cabinet body, a side of the cabinet body is open to form a cabinet opening, a cabinet door is rotatably installed at the cabinet opening, a sealing member is provided between the cabinet door and the cabinet body, and the sealing member can achieve sealing when the cabinet door blocks the cabinet opening. A fan is provided on the upper surface of the cabinet body, and an annular air supply ring pipe is rotatably installed at the upper end of the cabinet body, the axis of the air supply ring pipe is arranged vertically, and the inner ring of the air supply ring pipe has an upward air inlet, which is connected to one end of a hose, and the other end of the hose passes through the cabinet body and is connected to the fan.

[0007] Furthermore, the side wall of the air supply ring pipe is connected to a driving pipe, and the opening direction of the driving pipe is tangential to the air supply ring pipe. The air supply ring pipe also has multiple exhaust ports along its circumference, and the exhaust ports are inclined downward and toward the vertical side wall of the cabinet; a circular ventilation port is arranged at the top center of the cabinet, and the ventilation port is arranged coaxially with the air supply ring pipe, and the diameter of the ventilation port is less than half of the diameter of the air supply ring pipe.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] In this scheme, the exhaust port of the air supply ring pipe is tilted downward and toward the side wall of the cabinet, a prototype vent is set at the center of the top of the cabinet, and the air inlet of the air supply ring duct is connected to the fan. In this setting, the airflow discharged from the air supply ring pipe is ejected to the inner wall of the cabinet, and then the airflow continues to flow downward along the inner wall of the cabinet under the influence of the wall effect until the airflow flows to the center of the bottom wall of the cabinet, then changes direction and flows, and is discharged from the vent.

[0010] That is, this solution uses the air supply ring pipe to supply moisture-proof and dehumidifying airflow, and most of the airflow flows along the inner wall of the cabinet, which has a better dehumidification effect on the side walls of the cabinet. Compared with the prior art method of directly forming turbulence in the cabinet by exhausting air with a fan, this solution is convenient for using smaller fan power and shorter processing time to obtain better cabinet dehumidification and drying effects, which is conducive to achieving moisture-proof and sterilization of the cabinet.

[0011] In addition, a driving pipe is provided on the air supply ring pipe in the present solution, and the opening direction of the driving pipe is strictly tangential to the air supply ring pipe. When the fan supplies air to the air supply ring pipe, the airflow at the injection point of the driving pipe can drive the air supply ring pipe to rotate, so that the exhaust port on the air supply ring pipe blows air evenly toward the inner wall of the cabinet, so that the side wall of the cabinet is evenly dehumidified.

DETAILED DESCRIPTION

[0021] The exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not intended to exhaust all possible modes of the present invention, nor to limit the scope of the present invention.

[0022] Example 1

[0023] Reference Figure 1-Figure 5 One or more embodiments of the present invention provide a moisture-proof and sterilizing integrated cabinet, including a cabinet body 6, wherein the cabinet body 6 has an inner cavity 7, and one side of the cabinet body 6 is open to form a cabinet opening, and a cabinet door 1 is rotatably installed at the cabinet opening, and a sealing member is provided between the cabinet door 1 and the cabinet body 6, and the sealing member can achieve sealing when the cabinet door 1 blocks the cabinet opening. A fan 3 is provided on the upper surface of the cabinet body 6, and an annular air supply ring pipe 5 is rotatably installed at the upper end of the cabinet body 6, and the axis of the air supply ring pipe 5 is arranged vertically, and the inner ring of the air supply ring pipe 5 has an upward air inlet, which is connected to one end of a hose 52, and the other end of the hose 52 passes through the cabinet body 6 and is connected to the fan 3.

[0024] In this embodiment, the side wall of the air supply ring pipe 5 is connected to a driving pipe 51, and the opening direction of the driving pipe 51 is tangential to the air supply ring pipe 5. The air supply ring pipe 5 also has a plurality of exhaust ports along its circumference, and the exhaust ports are tilted downward and toward the vertical side wall of the cabinet 6; a circular vent is provided at the top center of the cabinet 6, and the vent is coaxially arranged with the air supply ring pipe 5, and the diameter of the vent is less than half of the diameter of the air supply ring pipe 5.

[0025] Specifically, the cabinet body 6 here is a square cabinet, and a square cavity is arranged inside the cabinet body 6. Similarly, the cabinet door 1 is a square plate-like structure, and the cabinet door 1 and the cabinet body 6 are rotatably connected by a hinge 2, and the hinge 2 is arranged on the side wall of the cabinet door 1 at the cabinet opening. In order to achieve the seal between the cabinet door 1 and the cabinet body 6, it is necessary to arrange a seal on the opposite sides of the cabinet door 1 and the cabinet body 6. Preferably, the seal here adopts a U-shaped rubber strip or a silicone strip. In addition, in order to raise the inner cavity 7 of the cabinet body 6 to reduce the influence of moisture on the ground, a base 12 is arranged at the lower part of the cabinet body 6.

[0026] Specifically, the fan 3 is a small fan 3, the air outlet of the fan 3 supplies air to the air supply ring pipe 5, and the fan 3 is driven by a small drive motor (not shown in the figure). The fan 3 and the drive motor are supported by the upper surface of the cabinet 6 respectively.

[0027] See also Figure 4 and Figure 5 , the air supply ring tube 5 of this embodiment is a circular ring structure, and the outer periphery of the air supply ring tube 5 has a plurality of air nozzles 53 arranged obliquely downward, and the opening direction of the air nozzles 53 is consistent with the direction of the exhaust port of the above-mentioned air supply ring tube 5. In order to realize the air intake of the air supply ring tube 5, an air inlet is also arranged on its inner periphery, and the air inlet is used to communicate with the air outlet of the fan 3 through a hose 52. As one of the preferred structural forms, six air nozzles 53 are arranged on the air supply ring tube 5, and the six air nozzles 53 are evenly distributed along the circumference of the air supply ring tube 5. In some other structural settings, the number of air nozzles 53 can be four or eight or other numbers, which can be set by those skilled in the art. In this embodiment, the air supply ring tube 5 is arranged horizontally, and its rotation axis extends in the vertical direction. In order to drive the air supply ring tube 5 to rotate, the above-mentioned drive tube 51 is arranged on the outer periphery of the air supply ring tube 5, one end of the drive tube 51 is connected to the air supply ring tube 5, and the other end forms a pipe mouth connected to the external environment. When the axial direction of the driving tube 51 is along the tangential direction of the air supply ring tube 5 , the gas is discharged outward from the driving tube 51 , and the reaction force applied by the air to the air supply ring tube 5 can drive the air supply ring tube 5 to rotate.

[0028] In this embodiment, the fan 3 is driven by an electric motor, and the cabinet 6 has a cylinder 4 passing through the vent, and the upper end of the cylinder 4 has an annular flange 41 extending outward, and the vertical projection of the fan 3 and the motor does not exceed the annular flange 41. Specifically, the air inlet of the fan 3 is connected to one end of the air inlet pipe 31, and the other end of the air inlet pipe 31 extends away from the vent.

[0029] In order to exhaust the inner cavity 7 of the cabinet 6, a vent is provided on the top wall of the cabinet 6. The vent is located at the center of the top wall of the cabinet 6. When in use, the air supply ring pipe 5 sprays the air flow obliquely downward toward the inner wall of the cabinet 6. The air flow obliquely flows downward along the inner wall of the cabinet 6 until it reaches the bottom wall of the inner cavity 7 of the cabinet 6. Then, because the air pressure at the center of the cabinet 6 is lower, the air flow reaching the bottom wall of the cabinet 6 at this time will flow toward the center of the bottom wall, and then flow vertically upward and be discharged from the vent.

[0030] The diameter of the ventilation opening mentioned above is less than half of the diameter of the air supply ring pipe 5. This arrangement can prevent the exhaust port of the air supply ring pipe 5 and the air nozzle 53 from being too close to the ventilation opening, and the air is discharged directly from the ventilation opening.

[0031] Specifically, the vent is a circular opening that passes through the top wall of the cabinet 6 from top to bottom, and the cylinder 4 is a circular cylinder. The outer annular surface of the cylinder 4 fits the inner annular surface of the vent, and the cylinder 4 is fixed to the top wall of the cabinet 6. In addition, the upper and lower ends of the cylinder 4 pass through the vent, respectively. In the case of using the hose 52, the lower end of the hose 52 passes through the upper end of the cylinder 4 in turn and enters the ventilation cavity 42 in the cylinder 4, and then passes through the ventilation cavity 42 from the lower end of the cylinder 4 and communicates with the air inlet of the air supply ring 5.

[0032] In some other structural arrangements, a shielding plate is installed above the cylinder 4, and the vertical projection of the cylinder 4 falls into the vertical projection of the shielding plate. This arrangement is convenient for reducing the probability of dust accumulation from the vent to the inner cavity 7 of the cabinet 6.

[0033] The hose 52 is elastic and can be stretched to facilitate the rotation of the air supply ring tube 5 around its own axis. Preferably, the hose 52 is a rubber tube, a silicone tube or a corrugated tube made of plastic.

[0034] In order to realize the rotational connection between the air supply ring pipe 5 and the cabinet body 6, in this embodiment, the top wall surface of the inner cavity 7 of the cabinet door 1 has an annular slide groove, which is coaxially arranged with the air supply ring pipe 5, and a slider 54 is installed on the slide groove, and the slider 54 is fixed to the air supply ring pipe 5.

[0035] Specifically, there are multiple sliders 54, and the multiple sliders 54 are evenly distributed along the circumference of the chute. Preferably, the number of sliders 54 is two. In other structural settings, the number of sliders 54 can be three or four or other numbers, which can be set by those skilled in the art.

[0036] In addition, in this embodiment, the slider 54 is a T-shaped slider 54 or a dovetail slider 54, and correspondingly, the slide groove is a T-shaped slide groove or a dovetail slide groove.

[0037] In order to guide the airflow on the bottom wall of the inner cavity 7 of the cabinet 6 , a boss 11 is provided at the center of the bottom wall of the inner cavity 7 of the cabinet 6 , and the cross-sectional area of ​​the boss 11 gradually decreases from bottom to top.

[0038] As one specific structural form, the boss 11 is a truncated cone-shaped boss. In some other structural arrangements, the boss 11 may be a quadrangular cone-shaped boss. The boss 11 here may also be in other shapes, which can be set by those skilled in the art.

[0039] Working principle: when dehumidification is not needed, the fan 3 is in a closed state, and the inner cavity 7 of the integrated cabinet is normally in the process of storing items.

[0040] When the cabinet needs to be dehumidified to prevent moisture and sterilize, the fan 3 is turned on, and the fan 3 supplies air to the air supply ring pipe 5. The air nozzle 53 on the air supply ring pipe 5 sprays airflow downwardly toward the side wall of the inner cavity 7 of the cabinet body 6. The airflow flows downward along the inner wall of the cabinet body 6, then flows toward the middle along the bottom wall of the cabinet body 6, and finally flows upward to flow out from the vent at the top of the cabinet body 6. Because the airflow for drying and dehumidifying in this embodiment flows along the inner wall of the cabinet body 6, it can perform better drying and dehumidification on the cabinet body 6 and the cabinet door 1 with a smaller airflow and a shorter ventilation time.

[0041] Example 2

[0042] The structure of this embodiment is basically the same as that of the first embodiment, and also provides a moisture-proof and sterilizing integrated cabinet. The difference is:

[0043] like Figure 6-Figure 8 As shown, in this embodiment, the inner cavity 7 of the cabinet 6 is installed with multiple horizontal support plate assemblies, each support plate group includes two support plates (i.e., the first support plate 8 and the second support plate 13 shown in the figure), one end of the support plate is rotatably connected to the inner wall surface of the cabinet 6 through a bracket, and the other end is suspended in the air to form a free end, and there is a gap 901 between the support plate and the inner wall surface of the cabinet 6; the two support plates in the same support plate group can be rotated to horizontally dock and position; the two support plates in the same support plate group can be rotated to tilt upward and position.

[0044] Specifically, a multi-layer support plate assembly is provided in the inner cavity 7 of the cabinet body 6, and different items are stored in layers by using the support plate assembly. When the integrated cabinet needs to be dehumidified to prevent moisture and sterilize: the items are taken out of the cabinet, and then the two support plates of the support plate assembly are tilted upward and positioned. Then, the two support plates used in pairs are combined to form a trumpet-shaped ventilation channel, which is convenient for gathering the gas in the entire cabinet inner cavity 7 to the middle of the cabinet and then discharging it upward.

[0045] In this embodiment, the cabinet body 6 has a first direction and a second direction which are horizontal and perpendicular to each other. The cabinet opening is arranged on the side of the cabinet body 6 perpendicular to the second direction. A support 9 is arranged on the side of the cabinet body 6 perpendicular to the first direction. A limit plate 10 is arranged on the support 9 to keep the support plate in a horizontal state. The support 9 is rotatably connected to the support plate.

[0046] Specifically, a rotating shaft is rotatably mounted on the bracket, and the rotating shaft is fixed to the support plate. There is a rotation damping between the rotating shaft and the bracket, and the damping prevents the rotating shaft from rotating with the bracket when the support plate is not subjected to external force. In some other structural settings, positioning pins can be used to achieve positioning when the support plate is rotated to an inclined upward position.

[0047] Example 3

[0048] The structure of this embodiment is basically the same as that of the first embodiment, and also provides a moisture-proof and sterilizing integrated cabinet. The difference is:

[0049] In this embodiment, the inner cavity 7 of the cabinet 6 is installed with multiple horizontal support plates (not shown in the figure), and the two ends of the support plates are fixed to the inner wall of the cabinet 6 through mounting seats (not shown in the figure). There is a gap 901 between the support plates and the inner wall of the cabinet 6, and the support plates are mesh plates and / or the middle part of the support plates has mesh holes running through them.

[0050] Refer to the arrangement of the support, the first support plate and the second support plate in the above embodiment 2. In this embodiment, the support plate and the mounting seat are integrally formed or fixed by gluing, bolting or the like.

[0051] At this time, the structural setting of the mesh does not hinder the airflow from passing through the support plate from bottom to top.

[0052] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make various combinations and modifications to the above-mentioned embodiments of the present invention under the guidance of the present invention without departing from the scope of the present invention.
