Description

[Technical field]

[0001] The present invention relates to a deodorizing and humidifying device that improves indoor environments, and more particularly to a deodorizing and humidifying device that efficiently exerts the adsorption power of charcoal steadily for a long period of time. [Background technology]

[0002] Conventionally, there have been various technologies to remove odors such as pet odors and indoor odors in the home, and chlorine odors and feces and urine odors in hospitals and nursing facilities. For example, there is deodorizing charcoal that takes advantage of the large specific surface area and material adsorption power of charcoal.

[0003] However, the conventional techniques have the following problems. For example, Patent Document 1, Patent Document 2, and other deodorizing devices installed in smoking rooms have the problem that the device scale is large. On the other hand, deodorizing charcoal for home use is a small, stationary type, but has the problem that only the surface part of the charcoal exerts its full deodorizing effect. As mentioned in the above document, although the efficiency of charcoal utilization can be increased by using power to pump air, there is a problem in that a constant air passage is formed, and charcoal that is not in the passage is utilized inefficiently. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 07-213852 [Patent Document 2] Patent Publication No. 2020-25828 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in view of the above, and an object of the present invention is to provide a deodorizing and humidity control device that is easy to use and has improved charcoal utilization efficiency. [Means for solving the problem]

[0006] The deodorizing and humidifying device according to claim 1 comprises a substantially rectangular cylindrical housing, a bottom body made of a breathable filter or net that is fixed or engaged to the bottom side of the housing, a charcoal bag with charcoal particles sealed in nonwoven fabric that has the same external shape as the inside of the housing and is laid on top of the bottom body, and a cover body that is fixed or engaged to the upper side of the housing at a predetermined height from the charcoal bag and is equipped with a fan that draws air from the bottom side to the top, the bottom body being in a raised position relative to the ground surface of the housing, and a vent hole having a cutout shape is formed around the lower side of the housing. 、 The charcoal bag is made of two rectangular non-woven fabric rims. but They are pasted together at a specified width. , this The edge portion The entire circumference of the housing is in contact with the inside It acts as a valve, and all or part of the charcoal bag Negative pressure from fans Floating The deformation of the edge releases pressure It is characterized by repeating the process of returning to the original state.

[0007] In other words, the invention of claim 1 draws air from the bottom where humidity is high, and uses negative pressure to expose the entire charcoal to air, thereby achieving effective dehumidification and deodorization. In addition, the movement allows air to come into contact with the entire charcoal (preventing stagnation), further enhancing the deodorizing and humidity-regulating effects.

[0008] The housing may have legs protruding from the inside at the four corners of the side surface (thus forming ventilation holes), or it may have a structure in which no separate legs are provided and arch shapes are cut out from the four corners to form ventilation holes so that the housing is self-supporting. When the bottom body is to be locked, for example, a bar may be provided on the inside of the housing. The lid covers the top of the cylinder to achieve efficient negative pressure. The shape of the charcoal bag is preferably a cushion-like shape that is flattened from top to bottom. The outer shape being the same as the inside of the housing refers to the state in which the charcoal bag abuts against the inner wall of the housing over its entire circumference. The particle size of the charcoal is set to a level that prevents the powdered charcoal from leaking out of the nonwoven fabric. For example, the major axis may be set to 2 mm to 7 mm. The repeated movement of the charcoal bag, all or part of which floats up and returns to its original position, can also be described as fluttering. The deformation of the charcoal bag caused by the nonwoven fabric and charcoal particles is not uniform, so it performs a non-steady and non-periodic movement, and the charcoal particles inside also change position relative to each other, which also works well for deodorizing and regulating humidity. The relationship between the charcoal bag and the fan is the exhaust force of the fan that makes the charcoal bag dance, or the amount of charcoal particles packed in. Also, the amount of charcoal packed in should not be too dense (full) so that the charcoal bag can be folded, but on the other hand, it should not be too loose (loose) so that it easily creases and bends at that point. The peripheral edge portion may be slightly larger than the inside of the housing and may be bent so as to abut against the inside of the housing.

[0009] Claim 2 The invention described in claim 1 The deodorizing and humidifying device described above is characterized in that the upper and lower nonwoven fabrics in approximately the center of the charcoal bag are pasted together when viewed in a plane, a hole of a predetermined diameter is drilled, and a regulating rod that is inserted into the hole and has an expanded diameter at the top is provided in the bottom body or housing.

[0010] That is, claims 2 The invention described above prevents the charcoal bag from shifting or rising excessively, and achieves stable operation over a long period of time. In other words, it prevents the bag from moving in one direction and turning into a steady air flow through the gap, and achieves smooth and random up and down movement and fluttering movement. It also prevents the charcoal bag from sticking to the lid. The manner in which the diameter is expanded is not particularly limited, and the upper part of the rod body may be bent at 90 degrees, or may have a bulged head like a screw. The restricting rod may be provided at a position other than the center. It is sufficient that the central portion is pasted together at a minimum level, and there is no prohibition on the formation of a band-like pasting that passes through the center, for example, like the character for "sun."

[0011] Claim 3 The deodorizing and humidifying device according to claim 1 OR 2The deodorizing and humidifying device according to the present invention is characterized in that the housing is made of wood and the charcoal is derived from coniferous trees.

[0012] That is, claims 3 This invention can be installed without feeling out of place in homes, offices, hospitals, and nursing homes. By using coniferous wood, the specific surface area is large, allowing for effective adsorption. Examples of materials for the case include Yoshino cedar and other cedars, and examples of materials for the charcoal include Japanese cypress. Japanese cypress charcoal forms a microscopic honeycomb structure and exhibits good adsorption properties. Note that multiple types of charcoal can be blended together for use. Furthermore, a wooden slit body or a kumiko board may be placed on top of the lid body to make the fan less visible and to enhance compatibility with Japanese-style rooms, etc.

[0013] Claim 4 The deodorizing and humidifying device according to claim 1 , 2 or 3 The deodorizing and humidifying device according to the present invention is characterized in that a handle is provided on the side of the housing for use when carrying the device.

[0014] In other words, the invention according to claim 4 can be easily moved, making it possible to deodorize and dehumidify the necessary places when needed. For example, the overall size may be length x width x height = (18cm~30cm) x (30cm x 50cm) x (20cm x 38cm), and the amount of charcoal enclosed may be 70g~520g. Effect of the Invention

[0015] According to the present invention, it is possible to provide a deodorizing and humidity control device that is easy to use and has improved charcoal utilization efficiency. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is an explanatory diagram showing the external configuration of a deodorizing and humidity control device of the present invention. Fig. 2 is a schematic diagram showing a partial cross section of a deodorizing and humidity control device of the present invention. Fig. 3 is a schematic diagram showing the configuration of a deodorizing and humidity control device of the present invention viewed from below an upper inner frame in a plan view. Fig. 4 is a schematic diagram showing the configuration of a deodorizing and humidity control device of the present invention viewed from below an upper inner frame in a plan view with a charcoal bag removed. For ease of explanation, the components in each drawing are drawn at a scale different from the actual scale.

[0018] The deodorizing and humidifying apparatus 1 mainly comprises a housing 10, a bottom filter 20, a charcoal bag 30, and a fan cover 40.

[0019] The housing 10 is a square cylinder with external dimensions of approximately 18 cm length x 25 cm width x 17 cm height, made from a 2 cm thick thinned Yoshino cedar board. The lower part of the side surface is cut out in an arc to form an air intake 11. The cutout is approximately 3 cm high.

[0020] The upper part of the housing 10 is formed with a frame edge 12 that protrudes outward, giving the housing an exterior shape with improved design. An upper inner frame 13 into which the fan cover 40 is fitted and locked is formed on the upper inside part of the housing 10, and similarly, a lower inner frame 14 into which the bottom filter 20 is fitted and locked is formed on the lower inside part of the housing 10. The lower inner frame 14 is located above the intake port 11, and the bottom filter 20 is in a raised position relative to the ground surface of the deodorizing and humidifying apparatus 1. In addition, a middle crossbar 15 is joined to the center of the lower inner frame 14 so as to bisect the lower inner frame 14 to form a "日" (Japanese character for sun) shape in plan view. A screw 151 is screwed upward into the center of the middle crossbar 15 (i.e., the central position of the housing 10 in plan view). The thickness of the screw 151 is an average of 2 mm in diameter, and the head is 5 mm in diameter. The head is located 3 cm above the middle crossbar 15.

[0021] Handles 16 are provided on both outer sides of the upper part of the vertical surface of the housing 10 to facilitate the carrying of the deodorizing and humidity-adjusting device 1. The weight of the deodorizing and humidity-adjusting device 1 is about 1 kg, and it can be easily moved. Thereby, a desired location or room can be easily deodorized or humidity-adjusted.

[0022] The bottom filter 20 has a shape conforming to the inner shape of the housing 10 and is a plastic filter plate with a 5 mm square mesh formed thereon. By making the eyes this large, the charcoal bag 30 is supported from below without obstructing the upward flow of air from the intake port 11. The position of the bottom filter 20 is determined by the lower inner frame 14 and is fitted into the housing 10.

[0023] The charcoal bag 30 is a futon-like bag in which hinoki charcoal grains 32 are enclosed in a non-woven fabric 31. The outer shape conforms to the inner shape of the housing 10 and is laid on the bottom filter 20. The non-woven fabric 31 is formed by bonding the peripheries of two non-woven fabrics, and a 1 cm wide edge 311 is formed at the periphery. Also, a 2 cm wide bonding 312 is formed in the center so as to divide the bag into two. The charcoal grains 32 are hinoki charcoal. When carbonizing or after carbonizing, crushing is performed, and the sieved ones with a generally major axis of 2 mm to 7 mm are enclosed. In particular, the fine charcoal that can pass through the mesh of the non-woven fabric 31 is removed. The enclosed amount is 100 g.

[0024] A hole 313 with a diameter of 5 mm is made in the center of the bonding 312, and the screw 151 is inserted here to enhance the posture stability of the charcoal bag 30.

[0025] The fan cover 40 has a flat cover part 41 of a predetermined thickness that is placed on the upper inner frame 13 to cover the top surface of the housing 10, and a large diameter fan 42 that fits inside the cover part 41 (the power supply and drive unit are not shown). Note that a guard 411 is formed on the cover part 41 from a safety standpoint. The fan 42 rotates in a direction to blow air from the inside of the housing 10 to the outside (from the bottom to the top). The distance between the top surface of the charcoal bag 30 and the bottom surface of the fan cover 40, i.e., the height of the hollow portion of the housing 10, is approximately 10 cm. The air volume (rotation speed) of the fan 42 is set to such an extent that the charcoal bag 30 gently dances within the housing 10, as will be described later.

[0026] The deodorizing and humidifying apparatus 1 is configured as described above. Air is taken in from the inlet 11 by the fan 42, passes through the charcoal bag 30, and is exhausted upward. Odor-causing substances with large molecular weights and air with high humidity tend to stagnate in the lower part of the room, so by sucking in air from the bottom and exhausting air from the top, effective deodorization and humidity control (dehumidification) is possible. In addition, because an air flow is created, odor-causing substances floating and diffusing in the room are ultimately taken in regardless of their molecular weight, and are deodorized sequentially through continuous operation. Similarly, humidity control (dehumidification) of the entire room is also achieved.

[0027] Here, since the edge 311 is in contact with the inside of the housing 10 over its entire circumference, it functions as a valve, and the charcoal bag 30 is entirely or partially lifted by the negative pressure of the fan 42. The charcoal bag 30, including the edge 311, deforms, and the resulting gap releases the pressure, causing the charcoal bag 30 to fall back onto the bottom filter 20.

[0028] Here, since the charcoal bag 30 is actually positioned by the screw 151, even if it falls down, the edge 311 will again come into contact with the inside of the housing 10. Therefore, the up and down movement of the charcoal bag 30 is repeated. Incidentally, even when the negative pressure of the fan 42 is large, the head of the screw 151 restricts the ascent of the charcoal bag 30, and the charcoal bag 30 moves back and forth up to the height of the screw 151.

[0029] This up and down movement (reciprocation) is non-steady and non-periodic because the charcoal bag is microscopically amorphous. Also, the charcoal grains 32 inside change position little by little due to the impact of falling over. Therefore, the "movement" of the bag and the "movement" of the grains realizes efficient deodorization or humidity control. In other words, in conventional deodorizing and humidity control methods in which charcoal is aerated, the charcoal is stationary, so an air passage is formed, and the charcoal in contact with this passage is highly efficiently utilized, but the charcoal or the contact parts of the charcoal grains in places with poor air flow are not efficiently utilized. On the other hand, in the deodorizing and humidifying device 1, the charcoal bag 30 moves up and down, and the charcoal grains 32 inside also move little by little (the contact points and contact partners change), so the air flow is not fixed, and in principle all the charcoal grains and the surfaces of each charcoal grain are used. Moreover, since the position is determined by the screw 151, the charcoal bag 30 does not shift to one side and a large opening is not formed between the inside of the housing 10 in a plan view. Therefore, stable and efficient deodorization and humidity control are realized for a long period of time.

[0030] As described above, the deodorizing and humidity control device 1 can be easily used and can achieve effective deodorization and humidity control with improved charcoal utilization efficiency. [Industrial Applicability]

[0031] The deodorizing and humidifying device 1 can be used not only in each room of a home, but also in nursing homes, hospitals, pet shops, etc. It can also be used in restaurants such as yakiniku restaurants. [Explanation of symbols]
