Description

  The present invention relates to a dehumidifier. More specifically, the present invention relates to a chemical dehumidifier using a dehumidifying agent.

  A dehumidifier is mainly a mechanical system and a chemical system that uses a dehumidifying agent as a device that absorbs moisture in the air. The chemical method is simple in structure and small in size, and can be conveniently used in a narrow, sealed space such as a closet. Here, a chloride such as calcium chloride or magnesium chloride is usually used as the dehumidifying agent. Since these substances have a strong water absorption, they can absorb air moisture. A dehumidifier using these dehumidifiers is generally required to have a dehumidifier and store water absorbed by the dehumidifier.

  Korean Published Patent Publication No. 2005-0008705 (published on Jan. 21, 2005, hereinafter referred to as this document) presents a dehumidifying device using a moisture absorbent. In this document, a water storage box is provided for storing a liquid flowing out of a moisture absorbent composed of calcium chloride. A dehumidifier mainly used at home usually uses a plastic box as a water storage box. Such a box-type dehumidifier has a structure in which a chloride such as calcium chloride or magnesium chloride is placed in a plastic box and the upper part thereof is sealed with a semipermeable membrane sheet. The semipermeable membrane sheet allows easy passage of single molecules such as air and vaporized water molecules through fine holes, but does not allow many groups of molecules bound in the liquid state to pass through. It plays a role to prevent leakage. A box-type dehumidifier is generally installed on the floor inside the closet.

  Such a box-type dehumidifier is structurally safe and is unlikely to fall down or be damaged by an impact, but only the top surface of the box is in contact with air and is surrounded by the wall of the box. Therefore, there is a problem that the dehumidification efficiency is lowered. In addition, when dehumidification is performed and the absorption liquid reaches a reference value or more, chloride is buried in the absorption liquid, causing a problem that the dehumidification ability is remarkably lowered. In the case of a dehumidifier that has been used, there is a problem that it is difficult to dispose of the dehumidifier because the absorbent and calcium chloride are mixed inside the box.

  There is a dehumidifier configured to replace only calcium chloride, but this is a structural problem, and the absorption liquid tends to flow out, and there is a high risk that the user's skin will come into contact with calcium chloride during replacement. There is a dehumidifying bag type dehumidifier that complements the disadvantages of such a box type dehumidifier. A dehumidifying bag type dehumidifier has a structure including a water storage unit that contains calcium chloride in a dehumidifying bag bonded with vinyl and a semipermeable membrane sheet and communicates with a lower portion of the dehumidifying bag. A connection channel is formed between the dehumidification bag and the water storage part, and the absorbing liquid flows and is stored in the lower water storage part through the connection channel in the dehumidification bag.

  Such a dehumidification bag has a large contact area with air compared to a box-type dehumidifier, and has a structure that is installed thinly and vertically, and is heated by melting heat and does not hinder air convection. There is. In addition, the volume is relatively smaller than that of the box-type dehumidifier, and there is an advantage that it can be easily discarded after use. However, in the case of such a dehumidifying bag type dehumidifier, it is usually installed on a closet hanger or made of vinyl and a semipermeable membrane sheet whose dehumidifying bag is not strong, and the absorbing liquid is stored in the water storage part. The more the product is stored, the greater the load and the greater the risk that the dehumidifying bag will burst.

In a closed space like a closet, the lower part is relatively humid and heavy, so it is advantageous to install a dehumidifier at the bottom to improve dehumidification efficiency, but most dehumidifying bag type dehumidifiers are Since it has to be installed over the hanger at the top of the closet, and the risk of breakage of the dehumidifying bag due to an increase in absorption liquid is great, there are many restrictions on the installation of the dehumidifier for increasing the efficiency of dehumidification.

  Further, in order to increase the strength of the dehumidifying bag, it is problematic that the connecting portion is made of another component made of a material such as plastic, which greatly increases the manufacturing cost.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  First, it should be noted that the same reference numerals are given to the components in each drawing so that the same components have the same reference numerals as much as possible even if they are displayed on other drawings. I must. In addition, the preferred embodiments of the present invention will be described below, and the technical idea of the present invention is not limited to this, and is not limited, and can be variously implemented by those skilled in the art.

  FIG. 1 is a view illustrating a dehumidifier according to an embodiment of the present invention, and FIG. 2 is a view illustrating a dehumidifying unit, an upper cover, and a lower water storage tank of the dehumidifier illustrated in FIG. In order to clearly understand the present invention conceptually, FIG. 1 and FIG. 2 clearly illustrate only the main features, and as a result, various modifications of the illustration are expected and illustrated. It is not necessary that the scope of the present invention be limited by the particular shape made. Referring to FIG. 1 and FIG. 2 in parallel, a dehumidifier according to a preferred embodiment of the present invention includes a dehumidifying unit (100), an upper cover (200), and a lower water storage tank (300).

  First, the dehumidifying unit (100) plays a role of absorbing moisture in the air by the absorbing power of the dehumidifying agent. Such a dehumidifying unit (100) may include a dehumidifying bag (110) and a water storage unit (120). The dehumidifying bag (110) is formed in the shape of a bag forming a space therein, and at least one surface is a semipermeable membrane sheet through which gas is permeated. The dehumidifying bag (110) can be formed in the form of a square envelope having a wide width and a small thickness. A dehumidifying agent is filled in the dehumidifying bag (110). Calcium chloride can be used as a dehumidifying agent. Here, the calcium chloride may be implemented to have various shapes such as a round ball type and a flake type.

  The dehumidifying bag (110) is formed so that a frame is bonded to form a space inside, but a hole is provided at the upper edge of the dehumidifying bag (110) to form a first hanging hole (111). Can be. In describing a preferred embodiment of the present invention, the first hanging hole (111) is exemplified as a part of the dehumidifying bag (110) is drilled to form the first hanging hole (111). The present invention is not limited to this.

  Such a dehumidifying bag (110) has a wider contact area with air and more active air convection than conventional box type dehumidifiers where the dehumidifying agent can be in contact with the air only by the upper semipermeable membrane sheet, and the efficiency of dehumidification Can be increased.

  The water storage part (120) is made of a waterproof material and plays a role of storing the absorption liquid flowing in from the dehumidifying bag (110). Such a water storage unit (120) is coupled to the lower portion of the dehumidification bag (110), and the absorbent in the dehumidification bag (110) is stored in the water storage unit (120) through the connection passage (123) by its own weight. The water reservoir (120) can be formed in the form of a square envelope having a wide width and a small thickness. Further, a folding line (122) can be formed in the width direction on the floor surface (121) of the water storage section (120). The folding line (122) is configured to be folded inward, and the folding line (122) is configured to gradually extend toward the outside due to an increase in the absorption liquid in the water reservoir (120). At this time, the water storage unit 120 is configured such that the cross-sectional area of the width gradually increases downward (see FIGS. 6 and 7). This is a configuration for supporting the dehumidifying unit (100) more stably in a state where the absorbing liquid is stored in the water storage unit (120).

  The water storage unit (120) is provided to the user with the folding line (122) folded inward, and various types of folding can be performed corresponding to the folding line (122) formed in the width direction on the floor surface (121). A line can additionally be formed throughout the reservoir (120). Further, the side surface and floor surface of the water storage unit (120) are integrally formed, and various folding lines connected to the folding line (122) are formed in the entire water storage unit (120) correspondingly. be able to.

  If the side surface and floor surface of the water storage section (120) are formed integrally, the water storage capacity can be easily expanded, but the strength of the water storage section (120) with the expanded water storage capacity may be reduced. In the dehumidifier according to a preferred embodiment of the present invention, the floor surface (121) of the water storage unit (120) is configured to be supported by the lower water storage tank (300). The side surface and floor surface of the water storage unit (120) can be formed integrally without any restrictions. This provides the advantage of greatly reducing the manufacturing cost of the dehumidifying unit (100).

  On the other hand, since the dehumidifying bag (110) and the water storage unit (120) are partitioned and formed in this way, the dehumidifying agent is buried in the absorption liquid, and the problem of the box type dehumidifier that lowers the dehumidifying efficiency is fundamental. Can be prevented.

  FIG. 3 is a view showing a second hanger of the upper cover shown in FIG. Referring to FIG. 2 and FIG. 3 in parallel, the upper cover (200) forms an upper space where the dehumidifying unit (100) is installed, and a ventilation port through which air flow in contact with the dehumidifying bag (110) is smoothly guided. (210) is formed. The top cover (200) can be implemented in the form of a roof with the lower side open and the upper side and surroundings formed on the wall, and the vent (210) has a mixture of circular and rectangular holes. Can be used.

  Meanwhile, referring to FIG. 3, a second hanger (220) is formed inside the upper surface of the upper cover (200). The second hanger (220) is engaged with the first hanging hole (111) formed in the dehumidifying bag (110) and supports the dehumidifying unit (100). The second hanger (220) may be formed in a ring shape by being extended inside the upper surface of the upper cover (200). However, the present invention is not limited to the form of the second hanger (220), and the second hanger (200) is configured to support the dehumidifying unit (100) so as to be mutually engaged with the first hanging hole (111). 220) can be implemented in various ways.

  The lower water storage tank (300) forms a lower space where the water storage part (120) is located, and is configured to be coupled to the upper cover (200). The lower water storage tank 300 may have a flat floor surface that is in contact with the floor surface of the water storage unit 120 and may be formed in an open shape on the upper side.

  FIG. 4 is a view showing a state where the dehumidifying unit is attached to the upper cover. Referring to FIG. 4, it can be confirmed that the dehumidifying unit (100) is attached to the upper cover (200). As shown in FIG. 4, the dehumidifying unit is in a state where the water storage part (120) is hung down by the second hanger (220) being engaged with the first hanging hole (111) illustrated in FIGS. 2 and 3. (100) hangs on the ceiling of the top cover (200). Further, even if a part of the dehumidifying unit (100) is broken and the absorbing liquid leaks, it can be temporarily stored in the lower water storage tank (300) to prevent damage due to external outflow.

  FIG. 5 is a diagram showing a state where the floor of the water storage section of the dehumidification unit is supported by the lower water storage tank when the dehumidification unit is attached to the upper cover.

  When the dehumidifying unit (100) is mounted on the upper cover (200) and the lower water storage tank (300) is coupled to the upper cover (200), the floor of the water storage unit (120) of the dehumidifying unit (100) is the lower water storage tank. Supported by (300). That is, as illustrated in FIG. 5, when the first hanging hole (111) is hung on the second hanger (220), it is the distance from the first hanging hole (111) to the floor of the water storage section (120). The second distance (L2) is formed longer than the first distance (L1) that is the distance from the second hanger (220) to the bottom inside the lower water storage tank (300). This is configured such that when the dehumidifying unit (100) is attached to the upper cover (200), the floor surface of the water storage unit (120) contacts the floor surface of the lower water storage tank (300).

  FIG. 6 is a view showing the flow of airflow around the dehumidifying unit, and FIG. 7 is a view showing a state in which the folding line of the water storage section is expanded and supported by the lower water storage tank.

  Referring to FIG. 6, the floor surface of the water storage unit (120) is expanded by storing the aqueous solution in which the dehumidifying agent of the dehumidification bag (110) is absorbed in the water storage unit (120), and the lower water storage tank (300). Forming a floor surface (310) and a support surface. Thereby, it is possible to prevent the first hook hole (111 in FIG. 2) from being damaged by the load of the absorbing liquid. Since the load increased by the absorbing liquid is supported by the floor surface (310) of the lower water storage tank (300), the capacity of the water storage part (120) can be greatly increased.

  On the other hand, when moisture is absorbed in the dehumidifying bag (110), heat of dissolution is generated and the air around the dehumidifying bag (110) is heated. As the air around the dehumidifying bag (110) is heated, an upward air flow is generated, and new air is continuously introduced around the dehumidifying bag (110) to perform efficient dehumidification.

  Unlike a conventional box-type dehumidifier that is in contact with air only on the upper side, a dehumidifier according to a preferred embodiment of the present invention is installed in a form in which a dehumidifying bag (110) is suspended vertically, It is formed so as to be in active contact with air, and effective dehumidification can be performed. On the other hand, conventional box type dehumidifiers not only have a small contact area with air, but also dissipate heat throughout the box. Therefore, air convection for effective dehumidification does not occur well. Thus, the configuration of the dehumidifying bag (110) suspended in the vertical direction increases the contact area between the air and the dehumidifying agent, induces an upward airflow around the dehumidifying bag (110), and effectively dehumidifies the dehumidifying bag. For generating convection.

  FIG. 7 is a view showing a state in which the folding line of the water storage unit is widened and supported by the lower water storage tank. As illustrated in FIG. 7, when the absorbing liquid is stored in the water storage section (120), the folding line (122) of the floor surface of the water storage section (120) spreads downward, so that the lower water storage tank ( 300) floor surface (310) and support surface. Here, the water storage part (120) is formed so that the cross-sectional area in the width direction is increasing downward with respect to the vertical direction (H), and can support the dehumidification unit (100) more stably. .

  FIG. 8 is a perspective view of a dehumidifier according to another embodiment of the present invention. As shown in FIG. 8, an incision hole (230) is provided on the upper surface of the upper cover (200). Through this incision hole (230), the upper part of the dehumidifying bag (110) having the first hanging hole (111) can be pulled out of the upper cover (200) and fixed to one end of the upper cover (200). The second hanger (220) on which the first hanging hole (111) on the upper stage of the dehumidifying bag (110) pulled out from the incision hole (230) hangs correspondingly is the upper cover (200) around the incision hole (230). It is formed on either the left or right side.

  When the second hanger (220) according to another embodiment is formed on the left and right sides of the upper cover (200) around the incision hole (230), the first hanging hole (111) is convenient without the left and right sections. Can be used for

  And two dehumidification units (100) smaller than the general size are stored in the dehumidifier, and one of the dehumidification units (100) is the first hanger (111) on the second hanger (220) formed on the left side The other one of the dehumidifying units (100) can be correspondingly hung with the first hanging hole (111) on the second hanger (220) formed on the right side. Of course, the number of the second hangers (220) formed on either the left or right side is the same as the number of the first hanging holes (111).

  FIG. 9 is a perspective view showing a state in which the upper stage of the dehumidifying bag is pulled out from the upper cover of the dehumidifier according to another embodiment of the present invention, and FIG. 10 is from the upper cover of the dehumidifier according to another embodiment of the present invention. It is a sectional side view which shows the state which pulled out the upper stage of the dehumidification bag.

  As shown in FIGS. 9 and 10, the incision hole (230) is drilled in the longitudinal direction of the center of the upper cover (200). Since the upper frame of the dehumidification bag (110) having the first hanging hole (111) is pulled out through the incision hole (230), the width of the incision hole (230) matches the upper edge of the dehumidification bag (110). Formed in width.

  Since a folding line (122) is opened in the width direction on the floor surface (121) of the water storage section (120), the bottom (121) is dehumidified so that it is folded inwardly around the folding line (122). Stored inside. Thereafter, when the absorbing liquid in the dehumidifying bag (110) is lowered to the water storage section (120), the floor surface (121) folded around the folding line (122) is expanded by the weight of the absorbing liquid, and left and right Unfolded.

  Thus, the floor surface (121) is a mechanism that can store as much of the absorbent as possible. In other words, the floor (121) was initially folded inward about the folding line (122) and installed so as to occupy a minimum amount of space inside the dehumidifier, but the absorbing liquid is stored in the water storage section (120). When lowered, the volume is expanded to the left and right to store a maximum amount of absorbent.

  FIG. 11 is a perspective view showing a state where the upper first hanging hole of the dehumidifying bag pulled out from the upper cover of the dehumidifier according to another embodiment of the present invention is hooked on the second hanger, and FIG. FIG. 6 is a side sectional view showing a state where a first hanging hole of an upper frame of a dehumidifying bag pulled out from an upper cover of a dehumidifier according to another embodiment is hooked on a second hanger.

  As shown in FIGS. 11 and 12, the first hanging hole is pulled out from the upper stage of the dehumidifying bag (110) having the first hanging hole (111) through the incision hole (230) formed in the upper cover (200). (111) is coupled to the second hanger (220) formed on the upper surface of the upper cover (200). Since the upper part of the dehumidifying bag (110) is pulled out through the incision hole (230), the upper part of the dehumidifying bag (110) filled with the dehumidifying agent is in close contact with the inner surface of the upper cover (200) without a margin. . In this way, the dehumidifying bag (110) is in close contact with the inner space without a dead space (dead space), so that the lower water storage tank (300) can be secured. Therefore, as the space is secured, the dehumidifying bag (110) can be filled with more dehumidifying agent and the capacity of the water storage unit (120) can be increased.

  In addition, as shown in FIG. 12, if the upper stage of the dehumidifying bag (110) is pulled out by the incision hole (230) and the first hanging hole (111) is put on the second hanger (220), the upper stage of the dehumidifying bag (110). Is supported in close contact with one surface of the upper cover (200). The installation method of such a dehumidifying unit (100) is simply the dehumidifying bag (110) first hanging hole (111) on the second hanger (220) formed inside the upper surface of the upper cover (200) together with FIG. Compared with the method in which the dehumidifying bag is applied, the entire upper surface of the dehumidifying bag (110) is brought into close contact with one surface of the upper cover (200), so that the dehumidifying unit (100) can be supported in a more stable state.

  On the other hand, a dehumidifying agent such as calcium chloride used in the dehumidifying bag (110) generally uses circular (biz) particles having a certain size. The dehumidifying bag (110) and the water storage part (120) are separated into a separating part in which vinyl and a semipermeable membrane sheet are thermally fused to a constant width, but a small passage is opened in a part of the separating part. The absorption liquid like water absorbed in the dehumidifying bag (110) passes under the water storage part (120), but the passage is narrow and particles of a certain size made of calcium chloride pass through. I can't. However, calcium chloride crystals and particles are fragile, and many of them become small debris or dissolve, the size is gradually reduced, and some of them cannot absorb all the moisture from the dehumidification bag (110). It passes through the narrow passage (123) in the state of calcium crystals or water unsaturation, and immediately falls to the lower water reservoir (120).

In addition, due to the chemical properties of calcium chloride, a solution of hexahydrate (CaCl ₂ · 6H ₂ O) that absorbs 6 water molecules is produced at a temperature below 29 ° C, but at a high temperature of 29 ° C to 45 ° C. Tetrahydrate (CaCl ₂ · 4H ₂ O), which has absorbed four water molecules, is generated in the solution and immediately falls into the water reservoir (120). Calcium chloride fragments and unsaturated calcium chloride that have moved to the lower reservoir (120) are blocked from outside air and cannot absorb moisture, and exist continuously and in an unsaturated state. When the temperature falls below 29 ° C., a precipitation phenomenon that turns into calcium chloride crystals appears. As a result, if the debris of calcium chloride and the tetrahydrate calcium chloride produced at a high temperature of 29 ° C. or more fall as they are into the lower water storage part (120), the dehumidification efficiency is lowered.

  In FIG. 13, it is possible to confirm the precipitation phenomenon in which calcium chloride fragments and tetrahydrated calcium chloride fall in the water storage section and change into crystals again. In order to solve such a problem, an isolation protrusion (125) is formed on the isolation part (124) of FIG. 14, as shown in FIG. 14, between the dehumidifying bag (110) and the water storage part (120). An isolation part (124) is formed. The isolation part (124) includes a connecting passage (123) for connecting the dehumidifying bag (110) and the water storage part (120). A plurality of isolation protrusions (125) are formed in the isolation part (124) so that an isolation space (126) like "U" is formed in the isolation part (124) to isolate debris of a dehumidifying agent such as calcium chloride. It is formed to protrude upward.

In the isolation space (126) between the isolation protrusions (125), calcium chloride fragments and unsaturated calcium chloride are temporarily stored. The specific gravity of anhydrous calcium chloride is 2.15, the specific gravity of hexahydrated calcium chloride (CaCl ₂・ 6H ₂ O) is 1.65, it is light and preferentially drops over the isolation protrusion (125) and drops into the water storage section (120). Thus, the calcium chloride fragments and unsaturated calcium chloride remaining in the dehumidifying bag (110) continue to absorb moisture and become hexahydrated calcium chloride. As a result, the dehumidification efficiency is increased. In this way, dehumidifier debris is not immediately dropped into the water storage part (120) through the connecting passage (123), but remains in the isolation space (126) and continues to absorb moisture, so that the dehumidifying effect can be enhanced.

The isolation part (124) is formed by fusing vinyl and a semipermeable membrane sheet with a width of 5 to 10 mm, the connecting passage (123) is opened with a width of 8 to 10 mm, and the isolation protrusion (125) is It extends from the surface of the isolation part (124) at a height of 3 to 10 mm and is formed by fusion bonding. The chemical formula of calcium chloride is CaCl ₂ . The molecular weight is 111.0, the melting point is 772, and the specific gravity is 2.15. The amount of water absorption of calcium chloride can theoretically be absorbed up to 14 times its own weight, but this is a special condition where the humidity in the air is 90% or more, and the actual amount of absorption is the weight of calcium chloride. Is almost the same. This means, for example, that 100 g of calcium chloride absorbs 100 g of water, and the molecular weight of six water molecules absorbed by one calcium chloride molecule is 108, which is almost the same as the molecular weight (111) of calcium chloride. Because.

  According to the embodiment, at a humidity of 60% and a temperature of 25 ° C., one calcium chloride molecule is combined with six water molecules to be liquefied and move to the lower water reservoir. By the way, the number of water molecules necessary for calcium chloride to change into a liquid differs depending on the temperature.

CaCl ₂ · 6H ₂ O hexahydrate at temperatures from -54.9 to 29 ° C, CaCl ₂ · 4H ₂ O tetrahydrate at 29 to 45 ° C, and CaCl ₂ · 2H ₂ O ₂ at 45 ° C and above When the hydrate is 175 ° C., a monohydrate of CaCl ₂ · H ₂ O is formed, and at 300 ° C., the anhydrous CaCl ₂ is formed. A "precipitation phenomenon" occurs in which crystals are regenerated from an aqueous solution of calcium chloride due to temperature changes.
