TWI902125B - Detachable dehumidifier with regeneration properties - Google Patents

Abstract

The invention relates to a detachable dehumidifier with regeneration properties, comprising a hot air supply unit and a moisture absorption tablet detachably coupled to a hot air outlet of the hot air supply unit for moisture absorption and regeneration treatment. The moisture absorption tablet includes a main body made primarily of porous moisture-absorbing material, which is pressed and solidified into a tablet-shaped structure with moisture-absorbing efficiency. This design eliminates the need for an external shell to contain the moisture-absorbing material. Additionally, during the pressing of the porous moisture-absorbing material into the tablet-shaped structure, multiple channels are formed that are evenly distributed in the deep layers of the moisture absorption tablet body, creating several ventilation pathways without the need for ducts. When the moisture absorption tablet is saturated and requires regeneration, it can be coupled with the hot air supply unit. The hot air generated by the hot air supply unit flows through the multiple channels inside the moisture absorption tablet, evenly reaching all corners of the tablet. This ensures a more uniform heating effect, resulting in optimal regeneration efficiency. Conversely, when the moisture absorption tablet is absorbing moisture, the multiple channels increase the contact surface between the moisture-absorbing material and the humid air from the surroundings, enhancing the moisture absorption efficiency of the tablet.

Description

Separable reversible dehumidifier

This invention relates to the field of dehumidification, and in particular to a dehumidifier that uses moisture-absorbing tablets as the main body, which can be coupled to a hot air supply unit for moisture absorption reduction treatment, or separated from the hot air supply unit to perform moisture absorption independently, and can be a separate reducible dehumidifier that does not require an outer shell to contain the moisture-absorbing material.

Note that the dehumidifier that uses porous moisture-absorbing material as raw material works on the principle that after the moisture-absorbing material absorbs moisture from the environment, it can be dried by heating and then resume its moisture-absorbing function.

Cases such as US 5673493, US06675492, CN 2444170Y, CN208794586, and JP 2012239998 all utilize the aforementioned technology to enable the reuse of moisture-absorbing materials.

However, in the aforementioned cases, the moisture-absorbing material is traditionally composed of numerous loose granules. In order to gather the numerous freely rolling granular moisture-absorbing materials, the design must house these numerous granular moisture-absorbing materials in a shell, which is usually made of plastic or metal.

This design has the following drawbacks in actual use:

1. Manufacturers must separately develop shells to contain these numerous granular moisture-absorbing materials, which not only incurs material and manufacturing costs for the shells, but also takes time to encapsulate these numerous granular moisture-absorbing materials inside the shells to prevent them from falling out, resulting in complicated assembly procedures and increased production costs.

2. The granular moisture-absorbing material encased inside the shell has a reduced surface area in direct contact with the humid air outside the shell due to the shell's obstruction, thus reducing the moisture absorption efficiency of the moisture-absorbing material.

3. When the product is discarded, in addition to the increase in shell waste, the shell must also be removed before waste can be sorted during recycling, which is quite inconvenient.

4. The contact area between numerous loose granular moisture-absorbing materials is small, so the heat transfer during the drying and reduction process is slow, which means that it takes more time to complete the drying and reduction process, which is not only time-consuming but also increases energy consumption.

5. When reducing the moisture-absorbing material inside the shell, the heat energy required to be delivered to the moisture-absorbing material is unevenly distributed, resulting in poor reduction effect of the moisture-absorbing material in the corners of the shell.

Another US patent, 9562699 B2, similar to this application, uses hot air to reduce the moisture absorption capacity of the absorbent material. However, like the aforementioned patents, it employs a conventional method of placing numerous granular absorbent materials within a shell. Therefore, in US patent 9562699 B2, when the absorbent material inside the shell needs to be dried and reduced, the shell is attached to a fan unit. Hot air generated by the fan unit passes through a duct built into the center of the shell, and then through perforations in the duct, delivering the necessary hot air for drying and reducing the absorbent material inside the shell. However, to prevent absorbent material particles from falling out of the duct, the diameter of the perforations must be smaller than the diameter of the absorbent material particles. The diameter of the duct is such that the tiny perforations on the duct become a bottleneck in the hot air delivery path, resulting in a reduction in the amount of hot air received by the moisture-absorbing material. At the same time, the ductwork also causes the moisture-absorbing material to be shielded by the duct wall, reducing the heated area. Furthermore, the ductwork occupies space within the casing, thus reducing the capacity of the moisture-absorbing material. In addition, US 9562699 B2, like many of the previous cases, also has the aforementioned five drawbacks.

In view of the shortcomings of the aforementioned prior art in practice, such as poor reduction efficiency, large shell volume, small moisture-absorbing material capacity, complicated assembly process, increased production cost, and inconvenient recycling, the inventor has developed the present invention.

The purpose of this invention is to provide a separate reducible dehumidifier, which uses porous moisture-absorbing material that is pressed and solidified into a columnar or block-shaped moisture-absorbing tablet. This allows the moisture-absorbing tablet to be dried and reduced directly at the hot air outlet of the hot air supply unit without the need for an outer shell. This constitutes a shell-less dehumidifier that does not require an outer shell to contain the moisture-absorbing material.

Another objective of this invention is to integrally mold the moisture-absorbing material into multiple channels distributed in various corners inside the moisture-absorbing tablet body, forming multiple ventilation paths that do not require ductwork. This allows the deeper layers of the moisture-absorbing material to have a larger contact surface with the humid air inside, thereby improving moisture absorption efficiency. Furthermore, the hot air generated by the hot air supply unit is evenly distributed through the multiple channels distributed deep inside the moisture-absorbing tablet body, while eliminating the bottleneck of hot air flow by eliminating the need for ductwork. This results in better heating of the moisture-absorbing material, achieving the goal of providing a dehumidifier with better reduction efficiency, stronger moisture absorption capacity, and lower cost.

The above-mentioned objective of this invention is achieved through the following techniques:

A separable reducible dehumidifier includes a desiccant tablet and a hot air supply unit. The desiccant tablet comprises a tablet body, which is made primarily of a porous desiccant material ground into powder, mixed with an adhesive, then molded and dried to solidify into a tablet-like structure with desiccant properties. During the pressing of the porous desiccant material into the tablet-like structure, a plurality of channels are integrally formed within the tablet body, evenly distributed throughout, constituting a plurality of channels. No ventilation path with ductwork is required. When the moisture-absorbing tablet becomes saturated with moisture and loses its moisture-absorbing capacity, it needs to be dried and reduced to restore its moisture-absorbing capacity. The moisture-absorbing tablet is coupled to the hot air outlet of the hot air supply unit. The hot air generated by the hot air supply unit is evenly delivered to all corners of the moisture-absorbing tablet body through multiple channels distributed deep inside the tablet body. In addition, when the moisture-absorbing tablet is needed to dehumidify the environment, it can be separated from the hot air supply unit and placed separately in the environment that needs dehumidification.

As described above, in the separate reducible dehumidifier, the desiccant tablet body has a rough surface that increases the desiccant absorption area and a plurality of internal channels.

As described above, in the separate reducible dehumidifier, the upper end of the desiccant tablet is connected to an upper seat, and the upper seat is provided with an exhaust port.

As described above, in the separate reversible dehumidifier, the upper base is equipped with a humidity sensing component.

In the separate reversible dehumidifier described above, the humidity sensing component is a moisture-absorbing color-changing element.

As described above, the separate reducible dehumidifier has an upper seat with a chamber for housing the moisture-absorbing color-changing element. The bottom of the chamber has a through hole, allowing the chamber to connect to the moisture-absorbing tablet body through the through hole. The chamber is covered with a transparent cover.

As described above, in the separate reducible dehumidifier, the lower end of the desiccant tablet is connected to a lower seat, the lower seat is provided with an air chamber formed by a concave cavity structure, and an air inlet that is movably coupled to the hot air supply unit, the air chamber and the air inlet being connected.

The advantages of this invention are:

1. The present invention directly molds the moisture-absorbing material into a columnar or block-shaped tablet with multiple channels, eliminating the need for a shell to encapsulate the moisture-absorbing material. This reduces the manufacturing and assembly process and lowers production costs.

2. Since the present invention directly molds the moisture-absorbing material into a columnar or block-shaped tablet with multiple channels, it does not need to be sealed with a plastic or other material shell. Therefore, it can reduce waste generation when the product is discarded, or when recycling resources, there is no need to remove the shell, making recycling convenient.

3. Since the moisture-absorbing tablets of this invention do not require a shell for packaging, the moisture-absorbing material is not blocked by the shell and can have a complete contact area with the outside air, thereby absorbing moisture more quickly and producing a better moisture-absorbing effect.

4. Since the moisture-absorbing tablets of this invention are formed into a solidified structure by high-pressure molding of powdered porous moisture-absorbing material, the moisture-absorbing material forms a tighter bond, thus having better thermal conductivity, which can shorten the drying and reduction time and achieve energy-saving effect.

5. Since the moisture-absorbing tablet of the present invention is pressed into a tablet-shaped structure, a plurality of channels evenly distributed deep inside the moisture-absorbing tablet body are integrally formed, forming a plurality of ventilation paths that do not require the installation of air ducts. Therefore, when the moisture-absorbing tablet is saturated with moisture and needs to undergo moisture reduction treatment, the hot air generated by the hot air supply unit can be evenly delivered to all corners inside the moisture-absorbing tablet body through the plurality of channels, thereby improving the reduction efficiency.

6. Since the present invention utilizes a plurality of channels evenly distributed deep inside the moisture-absorbing tablet body integrally formed by the moisture-absorbing material to form a plurality of ventilation paths that do not require the installation of air ducts, the conveying bottleneck caused by the hot air passing through the through holes on the air duct is eliminated when conveying hot air, which can reduce heat loss and improve reduction efficiency.

7. Since the present invention utilizes multiple channels evenly distributed deep inside the moisture-absorbing tablet body to form multiple ventilation paths that do not require ductwork, the moisture-absorbing material is not blocked by the wall of the duct, thereby increasing the heating area and improving the reduction efficiency.

8. Because the present invention utilizes a plurality of channels evenly distributed deep inside the moisture-absorbing tablet body, formed by integrally molding the moisture-absorbing material, multiple ventilation paths are constructed without the need for ductwork, thereby reducing the volume occupied by ductwork, increasing the volume of the moisture-absorbing material inside the moisture-absorbing tablet, and thus improving the moisture absorption capacity.

9. Since the lower end of the absorbent tablet body described in this invention is connected to a lower seat, and the lower seat is provided with a concave cavity structure forming an air chamber, the hot air generated by the hot air supply unit, before entering the plurality of channels inside the absorbent tablet body, is first diffused inside the air chamber formed by the cavity inside the lower seat, thereby allowing all parts inside the cavity to obtain a uniform positive pressure. Therefore, the hot air flow can be distributed equally and equally to each channel inside the absorbent tablet body, further enabling each corner inside the absorbent tablet body to obtain a uniform drying and reduction effect.

Please refer to Figures 1 through 3.

The present invention discloses a separate reducible dehumidifier, comprising a desiccant tablet 1 and a hot air supply unit 2; wherein: The desiccant tablet 1 comprises a desiccant tablet body 11, wherein the desiccant tablet body 11 is made primarily of a porous desiccant material ground into powder, pressed by a mold, and then dried and solidified into a tablet-shaped structure with desiccant properties. During the pressing of the porous desiccant material into the tablet-shaped structure, a plurality of channels 111 evenly distributed within the desiccant tablet body 11 are integrally formed, creating a plurality of ventilation paths that do not require ductwork.

Furthermore, in a preferred embodiment of the present invention’s separate reducible dehumidifier, the absorbent tablet body 11 has a rough surface to increase the absorbent surface area of the absorbent tablet body 11 and improve the absorbent effect.

In a preferred embodiment of the separate reducible dehumidifier of the present invention, the desiccant 1 further includes an upper seat 12, which is coupled to the upper end of the desiccant body 11, and the upper seat 12 is provided with at least one vent hole 121, which is connected to the channel 111 of the desiccant body 11, so that after the hot air flows into the desiccant body 11, the evaporated water vapor is discharged through the upper seat 12 and the vent hole 121.

In a preferred embodiment of the separate reducible dehumidifier of the present invention, the dehumidifying tablet 1 further includes a moisture sensing component 13, which is disposed on the upper seat 12. The moisture sensing component 13 is used to determine the degree of moisture absorption saturation of the dehumidifying tablet body 11. Typically, the moisture sensing component 13 includes a moisture-sensitive color-changing element, which is a moisture-sensitive color-changing material that changes color as the moisture absorption of the dehumidifying tablet body 11 increases, allowing the user to directly identify the color change of the moisture-sensitive color-changing material to determine whether the dehumidifying tablet body 11 needs to undergo drying and reduction operations.

In a preferred embodiment of the detachable reducible dehumidifier of the present invention, the upper seat 12 is provided with a chamber 122, the chamber 122 is for accommodating the humidity sensing component 13, and the bottom of the chamber 122 has a through hole 1221, so that the chamber 122 is connected to the moisture-absorbing tablet body 11 through the through hole 1221. A transparent cover 123 is also provided on the chamber 122 so that the humidity sensing component 13 is securely placed in the chamber 122. Therefore, the humidity sensing component 13 can sense the degree of moisture absorption of the moisture-absorbing tablet body 11 and change color according to its degree of moisture absorption. The user can determine whether the moisture-absorbing tablet body 11 needs to be dried and restored by observing the color of the humidity sensing component 13 through the transparent cover 123.

In a preferred embodiment of the separate reducible dehumidifier of the present invention, the desiccant tablet 1 further includes a lower seat 14, which is a concave cavity structure. When combined with the lower end of the desiccant tablet body 11, it defines a nearly closed air chamber 143 with the desiccant tablet body 11. The lower seat 14 is provided with an air inlet 141, which communicates with the air chamber 143, and the air chamber 143 communicates with a plurality of passages of the desiccant tablet body 11. Channels 111 are connected; when the moisture-absorbing tablet body 11 needs to be dried and reduced, the hot air supply unit 2 can input hot air flow from the air inlet 141, so that the hot air flow enters the air chamber 143 and diffuses, thereby allowing all parts of the entire cavity to obtain a uniform positive pressure, so that the hot air flow can be divided into equal pressure and equal amount into the multiple channels 111 of the moisture-absorbing tablet body 11, and uniformly dry and reduce the corners of the moisture-absorbing tablet body 11.

The hot air supply unit 2 is located below the desiccant tablet 1. The hot airflow passing through the channel 111 of the desiccant tablet body 11 of the desiccant tablet 1 originates from the hot air supply unit 2.

The hot air flow supplied by the hot air supply unit 2 is first diffused in the air chamber 143 formed by the cavity in the lower seat 14 through the air inlet 141. This allows the hot air flow to obtain a uniform positive pressure in all parts of the cavity. Therefore, the hot air flow can be distributed equally and equally to each channel 111 in the moisture-absorbing tablet body 11, which further promotes a uniform drying and reduction effect in all corners of the moisture-absorbing tablet body 11. Especially when the lower end of the absorbent tablet body 11 is connected to the lower seat 14, and the absorbent tablet 1 is coupled to the hot air supply unit 2, the air outlet 21 of the hot air supply unit 2 will correspond to the air inlet 141 sealed to the lower seat 14, so as to ensure that the hot air flow is evenly delivered into the plurality of channels 111.
