A method for controlling humidity in a constant humidity cabinet

Abstract

The invention discloses a volute humidity control method for a constant humidity cabinet, which belongs to the field of humidity control. The volute humidity control method for a constant humidity cabinet can greatly extend the flow path of a humid air flow in a smaller space through the setting of a volute shell, and can significantly improve the adsorption effect of moisture in the humid air flow by cooperating with a dehumidification layer wrapped on the surface of the volute shell to adsorb moisture in the humid air flow, and dehumidification is more sufficient. The wavy multiple protrusions on the surface of the dehumidification layer can increase the contact area with the humid air flow, and produce a certain obstruction to the humid air flow, thereby dispersing the humid air flow and enhancing the adsorption effect of moisture in the humid air flow. The comb plate inside the volute shell can support the volute shell, so that the volute shell is not easy to deform. At the same time, in the process of the humid air flow flowing along the inner side of the volute shell, the comb tooth end can play a role of squeezing and dispersing the humid air flow, so that the humid air flow is more fully in contact with the dehumidification layer, thereby improving the dehumidification effect.

Description

Technical Field

[0001] The invention relates to the field of humidity control, and more specifically to a constant humidity cabinet volute type humidity control method. Background Art

[0002] Museum cultural relic storage cabinets are used to preserve precious cultural relics. In order to prevent the cultural relics from deformation, quality change and failure, they can simulate a suitable storage environment for the cultural relics. The cabinet controls the humidity inside the cabinet by using built-in working modules. Due to its special functional effects, it can also be called a constant humidity cabinet.

[0003] The constant humidity cabinet of the present invention integrates the functions of humidification, dehumidification, purification, and real-time viewing in the prior art, and is the mainstream equipment currently dominated by the cultural and museum industry, with humidity priority and micro-environment control. It can effectively adjust the humidity and air cleanliness of the preservation environment, and avoid deformation, warping, crispness, discoloration, insect bites, and mildew of cultural relics that are sensitive to humidity and air pollutants (such as lacquered wood, paper, and embroidery), effectively reduce the natural damage rate of cultural relics in the collection, and improve the collection and preservation capabilities of cultural relics in the collection.

[0004] The constant humidity cabinet relies on its internal intelligent detection system to accurately determine the humidity of the environment inside the cabinet. Different types of cultural relics have different humidity requirements. Some require humidification, while others require dehumidification, and ultimately maintain a constant humidity. For example, some bronzes have a constant humidity of 20% RH, and some ancient books have a constant humidity of 60% RH. Existing constant humidity cabinets usually only use dehumidification particles for dehumidification. When the humid air flow passes through, the dehumidification particles are used to absorb the moisture in the air flow, thereby achieving dehumidification of the air flow. However, this dehumidification method has limited dehumidification due to the limited height of the dehumidification box and the relatively short dehumidification path, resulting in insufficient dehumidification. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a constant humidity cabinet volute humidity control method, which can greatly extend the flow path of the humid air flow in a smaller space, and cooperate with the dehumidification layer wrapped on the surface of the volute shell to adsorb moisture in the humid air flow, which can significantly improve the adsorption effect of moisture in the humid air flow and make dehumidification more sufficient.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A constant humidity cabinet volute humidity control method, comprising the following steps:

[0010] S1. Use humidity probes at different positions inside the constant humidity cabinet to monitor the humidity inside the constant humidity cabinet;

[0011] S2. When the humidity probe detects that the humidity inside the constant humidity cabinet is higher than the maximum threshold, the control module controls the dehumidification module to perform dehumidification:

[0012] The air duct module arranged at the bottom of the dehumidification module draws the external humid air into the dehumidification module, enters the volute casing through the air inlet, and flows along the volute casing for multiple turns, and uses the dehumidification layer wrapped on the surface of the volute casing to absorb the moisture in the humid air flow;

[0013] The wavy water-absorbing strips on the surface of the dehumidification layer increase the contact area with the wet air flow, and play a certain role in hindering the wet air flow, thereby enhancing the adsorption of moisture in the wet air flow;

[0014] The humid airflow generates a certain squeezing force on the water absorption strip under the action of the air duct module. While the water absorption strip absorbs the moisture in the humid airflow, it also deforms under the squeezing action of the humid airflow. During the deformation process of the water absorption strip, the moisture inside the water absorption strip is squeezed out and flows into the water guide cavity arranged inside the volute shell from the water guide hole on the volute shell, and is finally collected in the water collection box connected to the volute shell.

[0015] S3. Use a drain pipe to connect the water collecting box with the water storage tank of the humidification module, so that the water collected by the dehumidification effect of the volute dehumidification structure flows back to the water storage tank of the humidification module for subsequent humidification by the humidification module.

[0016] Furthermore, the constant humidity cabinet includes a cabinet body, and a temperature and humidity monitoring module, a dehumidification module and a humidification module are installed inside the cabinet body;

[0021] The humidification module is arranged in the cabinet near the bottom;

[0022] A control module is also provided at the upper end of the cabinet for intelligently controlling the constant humidity cabinet.

[0023] By setting up the volute casing, the dehumidification layer wrapped on the surface of the volute casing is used to adsorb moisture in the humid air flow, which can greatly extend the flow path of the humid air flow in a smaller space, thereby significantly improving the adsorption effect of moisture in the humid air flow and making the dehumidification more sufficient.

[0025] Furthermore, the support member includes a comb-shaped plate, both ends of which are fixed to the dehumidification layer, and both ends of the comb-shaped plate are comb tooth ends; when the wet air flow flows along the inner side of the volute casing and encounters the comb-shaped plate, it can only pass through the comb tooth ends, which can squeeze and disperse the wet air flow, thereby making the wet air flow contact with the dehumidification layer more fully and improving the dehumidification effect.

[0026] Furthermore, a fixing frame is fixedly connected to the end cover, an electric push rod is fixedly connected between the fixing frame and the side end of the volute casing, an elastic corrugated sleeve is fixedly connected between the volute casing and the peripheral side of the end cover, and a humidity sensor is connected to the dehumidification layer, which monitors the humidity of the dehumidification layer. When the humidity on the dehumidification layer exceeds a preset threshold, the volute casing is controlled by the control module to heat the dehumidification layer to achieve dehumidification of the dehumidification layer until the humidity value of the dehumidification layer reaches a preset value and the heating is stopped. While heating, the control module is used to control the electric push rod to extend so that the fixing frame moves the end cover away from the volute casing. At this time, the inner cavity of the volute casing is fully opened, and the elastic corrugated sleeve is used to enable moisture to be quickly discharged from the air outlet pipe, thereby improving the self-dehumidification efficiency.

[0033] 3. Beneficial effects

[0034] Compared with the prior art, the advantages of the present invention are:

[0035] (1) This solution uses a dehumidification layer wrapped on the surface of the volute casing to adsorb moisture in the humid air flow, which can greatly extend the flow path of the humid air flow in a smaller space, thereby significantly improving the adsorption effect of moisture in the humid air flow and making the dehumidification more sufficient;

[0036] (2) This solution can heat the dehumidification layer by setting the volute casing as a heating plate, remove the moisture inside the dehumidification layer, and realize the repeated use of the dehumidification layer; multiple support members equidistantly connected along the winding direction of the volute casing between two adjacent dehumidification layers can support the volute casing, so that the volute casing is not easily deformed;

[0037] (3) In this scheme, the comb-shaped plate is set. When the wet airflow flows along the inner side of the volute casing, it can only pass through the comb-tooth end when it encounters the comb-shaped plate, which can play a role in squeezing and dispersing the wet airflow, so that the wet airflow contacts the dehumidification layer more fully, thereby improving the dehumidification effect;

[0038] (4) In this solution, a plurality of protrusions are arranged at equal intervals on the surface of the dehumidification layer along the winding direction of the volute casing, and the plurality of protrusions are distributed on the surface of the dehumidification layer in a wave-like manner. The plurality of wave-like protrusions can increase the contact area with the humid airflow, and have a certain hindering effect on the humid airflow, thereby enhancing the adsorption effect of moisture in the humid airflow;

[0039] (5) In this solution, the water guide cavity, water guide hole and water absorption strip cooperate with each other. Under the action of the air duct module, the wet air flow has a high flow velocity, which can generate a certain extrusion force on the water absorption strip. While the water absorption strip absorbs the moisture in the wet air flow, it also deforms under the extrusion of the wet air flow. During the deformation process of the water absorption strip, the moisture inside the water absorption strip is squeezed out and flows into the water guide cavity from the water guide hole for collection.

[0040] (6) In this solution, a water guide pipe is fixedly inserted downward from the center of the volute casing, and the water guide pipe is connected to the water guide cavity, and the water collected in the water guide cavity is discharged outward through the water guide pipe;

[0041] (7) In this solution, a water collecting box is connected to the outer bottom end of the volute casing, and the water collecting box is connected to the bottom end of the water guide pipe. A drain pipe is fixedly connected to the bottom end of one side of the water collecting box, and the drain pipe is connected to the water storage tank of the humidification module, which is used to return the water collected in the water guide cavity to the water storage tank of the humidification module for use by the subsequent humidification module, so that the automatic auxiliary water addition function of the constant humidity cabinet can be realized;

[0042] (8) In this solution, an arc plate baffle is fixedly connected to the side of the water absorption strip away from the air inlet. The arc plate baffle is in the shape of a quarter of a hard circular tube. The arc plate baffle can ensure that the water squeezed out of the water absorption strip flows out from the water guide hole;

[0043] (9) In this solution, a water-proof layer is connected between the water-absorbing strip and the dehumidification layer, a drainage tube is fixedly connected to the water guide hole, and the end of the drainage tube away from the water-absorbing strip exceeds the cavity wall of the water guide cavity. The water-proof layer can effectively prevent the moisture in the water-absorbing strip from penetrating into the dehumidification layer, so as to ensure the moisture carrying capacity of the dehumidification layer;

[0044] (10) This solution is provided with an electric push rod, an elastic bellows sleeve, and a humidity sensor connected to the dehumidification layer. The humidity sensor monitors the humidity of the dehumidification layer. When the humidity on the dehumidification layer exceeds a preset threshold, the control module controls the volute casing to heat the dehumidification layer to achieve the dehumidification effect on the dehumidification layer until the humidity value of the dehumidification layer reaches a preset value and the heating is stopped. While heating, the control module is used to control the electric push rod to extend so that the fixed frame moves away from the volute casing with the end cover. At this time, the inner cavity of the volute casing is fully opened, and the elastic bellows sleeve is used to allow moisture to be quickly discharged from the air outlet pipe, thereby improving the self-dehumidification efficiency.

[0063] Embodiment 1:

[0064] See also Figure 2 Compared with the dehumidification constant humidity cabinet in the prior art, the constant humidity cabinet in this solution includes a cabinet body 101, the cabinet body 101 includes a shell and a partition component 102 arranged in the shell, the partition component 102 divides the cabinet body 101 into two layers, the upper and lower layers are respectively provided with separate switch doors 140, and the double-layer design can avoid the overall switch operation, which is more energy-saving. Fig.10 As shown, a 12-inch film screen 141 is installed on the switch door 140 of the cabinet 101, and a safety lock module is burned on its control circuit board. The safety lock module is used to control the locking and unlocking of the switch door 140, for example, using face recognition or fingerprint to perform unlocking operations.

[0065] The cabinet 101 is provided with an exhaust port 107 connected to the outside, a first revolving door 112 and a second revolving door 113 at the two exhaust ports 107, the first revolving door 112 and the second revolving door 113 are connected by a first spring 121 and a second spring 122, and a temperature and humidity monitoring module, a dehumidification module 103 and a humidification module 104 are installed inside the cabinet 101;

[0066] The temperature and humidity monitoring module includes a plurality of humidity probes arranged at different positions inside the cabinet 101;

[0067] The humidification module 104 is arranged near the bottom of the cabinet 101, and an air outlet is arranged on the humidification module 104. An air outlet channel is also installed on the inner side of the cabinet 101. The air outlet channel includes a main air outlet channel 105 connected to the air outlet and an air outlet fork channel 106 connected to the main air outlet channel 105. The outlet of the air outlet fork channel 106 faces the interior of the cabinet 101 or is connected to the air dispersion channel 108 inside the cabinet 101.

[0068] A control module 118 is also provided at the upper end of the cabinet 101 for intelligently controlling the constant humidity cabinet. By way of example, humidity thresholds, such as a maximum threshold and a minimum threshold, can be set. When the humidity in the cabinet is lower than the minimum threshold, the humidification module 104 is controlled to humidify. When the humidity in the cabinet is higher than the maximum threshold, the dehumidification module 103 is controlled to dehumidify. The exhaust port 107 is opened when the dehumidification structure inside the dehumidification module 103 is heated and dried, so as to discharge the dried moisture to the outside of the cabinet 101.

[0069] The dehumidification module 103 is disposed near the bottom of the cabinet 101 and includes a dehumidification module 123 and an air duct module;

[0070] See also Figure 3 The air duct module includes a plurality of exhaust fans 110 for sucking external humid air from the air inlet 111 into the dehumidification module 123 and discharging the dehumidified air. It should be further explained that in this scheme, a constant humidity cabinet volute humidity control method is used. The dehumidification module 123 is Figure 3 Not shown, it is considered Figure 3 The dehumidification granular dehumidification structure 109 is replaced by a dehumidification module 123.

[0071] The constant humidity cabinet used in the volute dehumidification method is improved based on the above existing structure: please refer to Figure 4 and Figure 5 The dehumidification module 123 includes a volute dehumidification structure, which includes a volute casing 124 and end covers 125 tightly arranged at both ends of the volute casing 124. An exhaust pipe 126 axially connected to the volute casing 124 is fixedly penetrated in the middle of the end cover 125. The surface of the volute casing 124 is wrapped with a dehumidification layer 138. The dehumidification layer 138 is made of the same material as the dehumidification particles commonly used in the constant humidity cabinet in the prior art. The lower end of the volute casing 124 is provided with an air intake 127. Through the setting of the volute casing 124, the dehumidification layer 138 wrapped on the surface of the volute casing 124 is used to adsorb moisture in the humid air flow, which can greatly extend the flow path of the humid air flow in a smaller space, thereby significantly improving the adsorption effect of moisture in the humid air flow and making the dehumidification more sufficient.

[0072] Specifically, the volute casing 124 is a heating plate, and the volute casing 124 can heat the dehumidification layer 138 to remove moisture inside the dehumidification layer 138, thereby achieving repeated use of the dehumidification layer 138.

[0073] A fixing frame 142 is fixedly connected to the end cover 125, an electric push rod 144 is fixedly connected between the fixing frame 142 and the side end of the volute casing 124, an elastic corrugated sleeve 143 is fixedly connected between the volute casing 124 and the peripheral side of the end cover 125, and a humidity sensor is connected to the dehumidification layer 138, and the humidity sensor monitors the humidity of the dehumidification layer 138. When the humidity on the dehumidification layer 138 exceeds a preset threshold, the volute casing 124 is controlled by the control module to heat the dehumidification layer 138 to achieve the dehumidification effect on the dehumidification layer 138, until the humidity value of the dehumidification layer 138 reaches a preset value, the heating is stopped, and while heating, the dehumidification layer 138 is heated by the control module. The control module controls the electric push rod 144 to extend, so that the fixing frame 142 moves away from the volute casing 124 with the end cover 125. At this time, the inner cavity of the volute casing 124 is fully opened, and the elastic bellows sleeve 143 is cooperated to enable moisture to be quickly discharged from the air outlet pipe 126, thereby improving the self-dehumidification efficiency. In order to further accelerate the discharge speed of moisture generated during the heating process of the dehumidification layer 138, a plurality of small holes are evenly arranged on the elastic bellows sleeve 143 for quickly discharging moisture. In order to ensure that the end cover 125 can be close to the volute casing 124 when dehumidifying the air, an annular groove for accommodating the elastic bellows sleeve 143 can be provided on the inner side of the end cover 125.

[0074] To further improve dehumidification, refer to Figure 6 and Figure 7 The surface of the dehumidification layer 138 is provided with a plurality of protrusions equidistantly along the winding direction of the volute casing 124, and the plurality of protrusions are distributed in a wave-like manner on the surface of the dehumidification layer 138; the plurality of wavy protrusions can increase the contact area with the humid air flow, and have a certain hindering effect on the humid air flow, thereby enhancing the adsorption effect on moisture in the humid air flow.

[0075] The above solution is further improved in that: please refer to Figure 7 A water guide cavity 132 is provided inside the volute casing 124, see Figure 7 and Figure 8 The outer surface of the upper half of each circle of the volute casing 124 and the inner surface of the lower half are both provided with a plurality of water guide holes 131 connected with the water guide cavity 132, and the water guide holes 131 penetrate the dehumidification layer 138, and the protrusions on the outer surface of the upper half of each circle of the volute casing 124 and the inner surface of the lower half are all water absorption strips 129, and the plurality of water absorption strips 129 are correspondingly provided at the plurality of water absorption holes 131, and the water absorption strips 129 are elastic moisture absorption materials, such as fine-pore sponges, HC hydrophilic cotton, etc.; the protrusions other than the water absorption strips 129 are all dehumidification materials of the same material as the dehumidification layer 138, please refer to Fig. 9The humid air flow has a relatively high flow velocity under the action of the air duct module, which can produce a certain squeezing force on the water absorbing strip 129. While the water absorbing strip 129 absorbs the moisture in the humid air flow, it also deforms under the squeezing action of the humid air flow. During the deformation process of the water absorbing strip 129, the moisture inside it is squeezed out and flows into the water guide cavity 132 from the water guide hole 131 for collection.

[0076] To quickly drain the water collected in the water guide cavity 132, refer to Figure 6 and Figure 7 The volute casing 124 is fixedly provided with a water pipe 133 extending downward from the center thereof, and the water pipe 133 is connected to the water guiding chamber 132; the water collected in the water guiding chamber 132 is discharged outward through the water pipe 133; the outer bottom end of the volute casing 124 is connected with a water collecting box 128, and the water collecting box 128 is connected to the bottom end of the water guiding pipe 133; the bottom end of one side of the water collecting box 128 is fixedly connected with a drain pipe 135; the water collected in the water guiding chamber 132 is discharged outward through the water pipe 1 33 water collection box 128, and finally drained out through the drain pipe 135. In order to reasonably utilize water resources, the drain pipe 135 is connected to the water storage tank of the humidification module 104, and the water collected in the water guide cavity 132 is returned to the water storage tank of the constant humidity cabinet for subsequent use by the humidification module 104. In this way, the automatic auxiliary water addition function of the constant humidity cabinet can be realized. Especially in the south, the water collected by the constant humidity cabinet can basically meet the water needs for humidification, and even achieve the effect of no water addition. For example, if the target humidity is 60% RH, during winter humidification, assuming that the environment of the constant humidity cabinet is 50% RH, then water can be collected from the air and then used for the humidification module 104, so that the humidity in the cabinet is always maintained at 60% RH.

[0077] In order to ensure that the water squeezed out from the water absorbing strip 129 flows out from the water guide hole 131, please refer to Figure 8 A curved plate baffle 130 is fixedly connected to one side of the water absorption strip 129 away from the air inlet 127 , and the curved plate baffle 130 is in the shape of a quarter of a hard circular tube.

[0078] Among them, see Figure 8 A waterproof layer is connected between the water absorption strip 129 and the dehumidification layer 138, and a drainage tube 139 is fixedly connected to the water guide hole 131, and the end of the drainage tube 139 away from the water absorption strip 129 exceeds the cavity wall of the water guide cavity 132; the waterproof layer can effectively prevent the moisture in the water absorption strip 129 from penetrating into the dehumidification layer 138 to ensure the moisture carrying capacity of the dehumidification layer 138, and the drainage tube 139 is made of waterproof material, which can also effectively prevent the moisture in the water absorption strip 129 from penetrating into the dehumidification layer 138, and can also effectively prevent the water in the water guide cavity 132 from flowing back into the water absorption strip 129.

[0079] like Figure 1 As shown, the steps of the constant humidity cabinet volute dehumidification method are as follows:

[0080] S1, using humidity probes at different positions inside the cabinet 101 to monitor the humidity inside the cabinet 101;

[0081] S2. When the humidity probe detects that the humidity inside the cabinet 101 is higher than the maximum threshold, the control module 118 is used to control the dehumidification module 103 to perform dehumidification. The dehumidification method of the dehumidification module 103 is as follows:

[0082] The air duct module disposed at the lower part of the dehumidification module 123 sucks the external humid air into the dehumidification module 123, enters the volute casing 124 through the air inlet 127, and flows along the volute casing 124 for multiple turns, and uses the dehumidification layer 138 wrapped on the surface of the volute casing 124 to absorb the moisture in the humid air flow;

[0083] The plurality of wavy water-absorbing strips 129 are used to increase the contact area with the wet air flow, and to have a certain blocking effect on the wet air flow, thereby enhancing the absorption of water in the wet air flow;

[0084] The wet airflow exerts a certain squeezing force on the water absorbing strip 129 under the action of the air duct module. The water absorbing strip 129 absorbs the water in the wet airflow and deforms under the squeezing action of the wet airflow. The water inside the water absorbing strip 129 is squeezed out during the deformation process and flows into the water guiding cavity 132 from the water guiding hole 131 and is finally collected in the water collecting box 128.

[0085] S3. Use the drain pipe 135 to connect the water collecting box 128 with the water storage tank of the humidification module 104, so that the water collected by the dehumidification effect of the volute dehumidification structure flows back to the water storage tank of the humidification module 104 for subsequent humidification by the humidification module 104.

[0086] Compared with the prior art that uses dehumidification particles for dehumidification, which has the defect of a relatively short dehumidification path and leads to insufficient dehumidification, the present solution, through the provision of a volute casing 124, utilizes the dehumidification layer 138 wrapped on the surface of the volute casing 124 to adsorb moisture in the humid air flow, which can greatly extend the flow path of the humid air flow in a smaller space, thereby significantly improving the adsorption effect of moisture in the humid air flow and making the dehumidification more sufficient; the multiple wavy protrusions on the surface of the dehumidification layer 138 can increase the contact area with the humid air flow, and have a certain hindering effect on the humid air flow, thereby enhancing the adsorption effect of moisture in the humid air flow; the volute casing 124 can heat the dehumidification layer 138, remove the moisture inside the dehumidification layer 138, and realize the repeated use of the dehumidification layer 138.

[0087] Embodiment 2:

[0088] In the present embodiment, a support member 136 including a comb-shaped plate 137 is used to replace the protrusion including the water absorption strip 129. Compared with the protrusion including the water absorption strip 129 provided in Example 1, the support member 136 including the comb-shaped plate 137 in the present embodiment can simplify the internal structure of the volute casing 124, and accordingly, also reduce the preparation cost of the constant humidity cabinet.

[0089] Specifically, Fig.11 As shown, a plurality of support members 136 are equidistantly connected between two adjacent dehumidification layers 138 along the winding direction of the volute casing 124; the support members 136 can support the volute casing 124 so that the volute casing 124 is not easily deformed. Fig.12 As shown, the support member 136 includes a comb plate 137, both ends of which are fixed to the dehumidification layer 138, and both ends of the comb plate 137 are comb tooth ends 134; when the wet air flow flows along the inner side of the volute casing 124 and encounters the comb plate 137, it can only pass through the comb tooth ends 134, which can squeeze and disperse the wet air flow, thereby making the wet air flow contact with the dehumidification layer 138 more fully, thereby improving the dehumidification effect.

[0090] Embodiment 3:

[0091] The dehumidification module 103 also includes Figure 3 The dehumidification granular dehumidification structure 109 in the prior art shown in the figure comprises a placement slot and dehumidification particles located inside the placement slot. A heating element is arranged inside the placement slot for heating the dehumidification particles to remove moisture inside the dehumidification particles so that the dehumidification particles can be reused. The placement slot is located on the upper side of the volute dehumidification structure. The dehumidification module 123 using the volute dehumidification structure is arranged on the upper side of the volute dehumidification structure. Figure 3 Not shown; the airflow after dehumidification by the volute dehumidification structure passes through the placement groove, and the dehumidification particles inside the placement groove absorb moisture on the airflow again to further improve the dehumidification effect.

[0092] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
