Description

  The present invention relates to the technology of a box that draws in hot air. Specifically, the hot air sent from the hot air heating device is taken into the kotatsu, the thermal energy generated from the hot air heating device is efficiently used, and further expanded. The present invention relates to a technology of a heating auxiliary appliance that performs a multi-purpose function such as a table, chair, pedestal, step stool, or storage shelf.

  Conventionally, various types of heating equipment such as hot air heaters, kotatsu, and oil stoves have been used as a means to overcome the cold in winter. Among them, there is kotatsu as a heating appliance peculiar to Japan. Kotatsu is a type in which a special comforter is hung on a table, a top plate is further placed thereon, and a heating part is provided inside. Among the kotatsu, there are general ones that are placed directly on the floor, digging kotatsu, and in recent years the usual table type kotatsu. All kotatsu currently have a structure with an infrared heater on the back of the upper center of the kotatsu.

  Kotatsu mainly heats the lower body, and is usually used in combination with warm air heaters such as a warm air heater to warm the entire room. However, using other heating appliances such as a stove in addition to the kotatsu has a problem of wasting utility costs. In addition, hot air heaters use heat obtained by burning fossil fuels such as kerosene, so that the room can be heated relatively quickly, whereas Kotatsu is heated by electricity, so it can be used in a narrow range. Nevertheless, it has the disadvantage that it takes a relatively long time to raise the temperature in the kotatsu.

  For this reason, it is conceivable that the warm air of the warm air heater is directly guided into the kotatsu and the inside of the kotatsu is warmed, and an apparatus for guiding the warm air with a cylindrical duct or the like is known. However, when a duct is always installed, there are problems that the number of people who can use the kotatsu is reduced, and that a duct storage place other than the time of use is secured. For this reason, there is a need for an auxiliary tool that can efficiently and easily guide hot air from a hot air heater or the like into the kotatsu, and that can incorporate hot air into a kotatsu that can be used effectively when not in use. Yes.

  Various techniques have been proposed in the past to solve such problems. For example, Patent Document 1 proposes a technique in which the name of the invention is “hot air draw-in duct for kotatsu”, which is a known technique (see Patent Document 1). Specifically, “The hot air emitted from a hot air heater or the like and combined with a table are not equipped with a heat generating part such as a dedicated heater inside, but the same temperature as a normal kotatsu. `` Provide a hot air inlet duct for a kotatsu that can constitute an effective kotatsu '', and the solution is `` It is arranged with the open end facing the hot air outlet of the hot air heater and the hot air flows in A hot air inflow pipe that is connected to the other end of the hot air inflow pipe, forms a single tube, the open end is drawn into the kotatsu, and the hot air outflow pipe flows out of the hot air. The warm air blown from the warm air heater can be blown into the kotatsu via the warm air inflow pipe 2 and the warm air outflow pipe. However, with such technology, the hot air from the hot air heater can be guided into the kotatsu, but a hot air inflow pipe must be installed between the heater and the kotatsu, and pipe storage other than when it is used is stored. A place is needed.

  Patent Document 2 proposes a technique in which the name of the device is “warm air drawing device”, which is a known technique (see Patent Document 2). Specifically, the issue is to “simplify the structure of the appliance body more than before, improve the efficiency of heating during use, save fuel consumption such as oil or gas, and increase the power saving effect”. In the hot air drawing device for drawing hot air discharged from the fan heater air outlet into the kotatsu, the solution means, a hot air collecting part disposed in the vicinity of the fan heater air outlet, A duct connected to the collecting section and arranged toward the closed space of the kotatsu, and the hot air collecting section is a so-called Ito can that is a rectangular parallelepiped metal can, and the fan of the hot air collecting section An opening for sending warm air to the air outlet side of the heater is formed, the duct is made of a cylindrical metal conduit, and one end of the duct is connected to the bottom of the wall facing the opening of the hot air collecting part With a communication hole for That. However, in such a technique, there are many problems such as a duct for taking in warm air impairs the beauty and the number of people using kotatsu decreases. In addition, there is a problem that a storage space for the duct is required in a season when it is not used.

  Patent Document 3 proposes a technique in which the name of the invention is “kotatsu fan for oil stove”, which is a known technique (see Patent Document 3). The challenge is to provide a kotatsu fan for an oil stove that can save energy costs even with an oil stove that does not have a blower unit, by installing a blower with an appropriate amount of airflow in a hot air duct. As a solution to this problem, “a function of providing a blower at the upper part of the leg part and drawing hot air from the upper part of the oil stove into the inside of the kotatsu via the hot air duct” is adopted. However, with such technology, although warm air generated from a heater without a blower mechanism can be guided into the kotatsu, a hot air inflow pipe must be installed between the heater and the kotatsu, and the pipes are cleaned up. As for storage, it is necessary to transport to the storage place at the time of removal, and the problem of the present invention has not been solved.

  In order to solve these problems, the present inventor can take hot air from hot air heating equipment into the kotatsu, and can also use other usage methods that can avoid problems such as the storage place other than during use. This leads to the proposal of a multi-box with a multi-purpose kotatsu hot air intake.

  The hot air intake multi-box 1 according to the present invention is arranged on a part of the outer periphery of the kotatsu K, and the hot air W is guided into the kotatsu K by covering a part of the kotatsu futon. The greatest feature is to effectively use the generated thermal energy. Hereinafter, description will be given based on the drawings. The overall shape and the shape of each part of the hot air intake multi-box 1 shown in the present embodiment are not limited to the embodiments described below, but are within the scope of the technical idea of the present invention, that is, the same. It can change within the range of the shape and dimension which can exhibit the effect of this.

  FIG. 1 is an explanatory cross-sectional view illustrating a use state of a hot air intake multi-box 1 according to the present invention. The hot air intake multi-box 1 according to the present invention is a box made of a polyhedron that allows hot air W to be taken into the kotatsu K, and includes an opening 11 on the hot air heating device F side and an inner side of the kotatsu K side. At least two surfaces of the opening portion 12 are constituted by a main body portion 10 that is open. The main body portion 10 includes a ventilation portion 20 and a reinforcement portion 30, and the reinforcement portion 30 is formed from the hot air heating device F. By providing the ventilation part 20 for ventilating the warm air W, and having the reinforcement part 30, it has a configuration with strength as an expansion table, chair, pedestal, step board, or storage shelf. Yes.

  The main body 10 is a main body that constitutes the entire hot air intake multi-box 1 according to the present invention, the shape is a polyhedron, and the opening 11 on the hot air heating device F side and at least two surfaces. It has an opening 12 on the kotatsu K side. In FIG. 1, since it is represented by a cross section, it is not shown three-dimensionally, but the main body 10 shows a rectangular parallelepiped as an example. In addition, about a magnitude | size, if it comprises so that the height from a floor to an upper surface part may correspond with the position of the top plate of Kotatsu K, it can be set as an expansion table. On the other hand, when the height is lower than the top plate of Kotatsu K, it can be used as an auxiliary chair for children.

  Further, the main body 10 is preferably a rectangular parallelepiped, and such a shape is the shape that contributes to the most versatile use, and can be the ventilation portion 20 that does not cause fluid resistance in the flow path of the hot air W. . In addition, it is also effective to use a regular hexahedron having the same dimensions for the two surfaces on which the opposing opening 11 and opening 12 are provided and the other four surfaces. In this case, the opening 11 and the opening 12 are parallel. However, other than the regular hexahedron, there are those whose opposing surfaces are not parallel. However, it is not necessary to remove such a three-dimensional shape from the shape of the main body 10, for example, even when the opening 11 is at a low position, the opening 12 is at a high position, and the arrangement configuration is not parallel. It may be suitable for the flow path of the warm air W to follow the rising flow of the warm air W due to the temperature difference.

  The opening 11 is a ventilation opening that is opened to take in the hot air W from the hot air heating device F, and the opening 12 is for sending out the hot air W taken into the main body 10 into the inside of the kotatsu K. It is a vent opening opened in The opening 11 and the opening 12 serve as an entrance / exit of a hollow portion that communicates with the reinforcing portion 30.

  The ventilation section 20 is a flow path of the warm air W formed by the reinforcing section 30, and does not interfere with the flow path of the warm air W that is blown, and sufficiently responds to the warm air W from the warm air heating device F. It has a shape that blows air to the inside of K, and has a shape that suppresses fluid resistance as much as possible and does not cause turbulence. Specifically, the wall surface in the direction perpendicular to the insertion direction is reduced, and the shape is a circle, an ellipse, or a blade shape having the flow path direction as a longitudinal direction. In addition, by restricting the size of the ventilation part 20, it becomes possible to prevent the pet from entering the inside of the kotatsu via the hot air intake multi-box 1 according to the present invention.

  The reinforcing portion 30 has a strength that can withstand even if a user rides on the upper surface of the main body portion 10, and in order to make the strength constant regardless of which surface of the main body portion 10 is the upper surface, the horizontal direction and the vertical direction It is necessary to have a shape and configuration in which the stress applied to the surface is made uniform. Specifically, for example, as shown in FIG. 2 (a), a reinforcing part 30 is provided in a cross shape or an X shape in the approximate center inside the main body 10, or as shown in FIG. 2 (b). In addition, reinforcing portions 30 may be provided in the vicinity of the opening 11 and in the vicinity of the opening 12, respectively. Moreover, although not shown in drawing, the structure which provides the reinforcement part 30 three or more places may be sufficient. By providing a large number of locations where the reinforcing portions 30 are provided, the thickness of each reinforcing portion 30 in the flow path direction can be reduced.

  Although not shown in the drawings, the ventilation amount adjusting mechanism 31 is a mechanism that changes the shape of the ventilation portion 20 by changing the shape of the reinforcement portion 30 provided inside the main body 10 by operating from the outside. It is. Specifically, for example, it is conceivable that the amount of ventilation can be adjusted by changing the size of the opening hole serving as the ventilation portion 20 like a shutter structure of a camera. Moreover, the structure which makes variable the opening area of the ventilation part 20 by making the ventilation part 20 provided in the reinforcement part 30 into many slits, and sliding the plate-shaped member provided with the slit corresponding to the slit concerned.

  The warm air heating device F is assumed to be a general device that burns fossil fuel such as oil and sends out the warm air W by an electric fan. However, it is possible to use a wood stove without an electric fan or a fireplace provided with a blower, and there is no particular limitation as long as a heat source and a blower are provided.

  FIG. 3 shows the shape or configuration of the reinforcing portion 30 viewed from the openings 11 and 12, and FIG. 3 (a) shows that the reinforcing portion 30 in the case where the main body portion 10 is a rectangular parallelepiped is equally four wall portions from the center. FIG. 3B shows a configuration in which the reinforcing portion 30 in the case where the main body portion 10 is a rectangular parallelepiped is provided radially toward the four corners evenly from the center. 3 (c) shows a configuration in which the reinforcing portion 30 is provided from the four wall surfaces toward the adjacent wall portion when the main body portion 10 is a rectangular parallelepiped, and FIG. 3 (d) shows the main body portion. FIG. 3E shows a configuration in which the reinforcing portions 30 in the case where 10 is a rectangular parallelepiped are provided in a lattice shape or a net shape, and FIG. 3E shows the reinforcing portions 30 isotropically extending from the center of the main body portion 10 toward the opening direction. The example shown is shown.

  In the configuration of the reinforcing portion 30 shown in FIG. 3A, the wall surface of the main body portion 10 acts horizontally or vertically on the stress acting on the reinforcing portion 30 regardless of which surface is used as the top surface, side surface, or bottom surface. Therefore, it is difficult to buckle. Therefore, even if the user rides as a pedestal, it is a reinforced configuration that is not easily deformed.

Therefore, it is difficult to deform. Therefore, even if a user rides as a pedestal, it is a reinforced configuration that is not easily damaged.

  The structure of the reinforcing portion 30 shown in FIG. 3C is also a reinforcing structure that can easily withstand human loads because the action of stress is dispersed in the same manner as that shown in FIGS. 3A and 3B. is there. However, since the above reinforcing structure makes it difficult to secure the ventilation portion 20 if priority is given to strength, the ventilation portion 20 is secured by providing a plurality of reinforcement portions 30 as shown in FIG. Consider what to do.

  In the configuration of the reinforcing portion 30 shown in FIG. 3D, the reinforcing portion 30 having a lattice shape or a net shape is provided in order to sufficiently secure the ventilation portion 20 as described above. By adopting such a configuration, it is possible to ensure a sufficient ventilation portion 20. However, in such a configuration, it is considered that the rigidity of the reinforcing portion 30 itself is insufficient, so that it is necessary to provide a plurality of locations where the reinforcing portion 30 is provided or to increase the thickness of the main body portion 10. That is, the dimensions and materials are appropriately selected in consideration of the overall weight, rigidity, ventilation rate, internal shape, and cost.

  In the configuration of the reinforcing portion 30 shown in FIG. 3E, an example is shown in which the reinforcing portion 30 is isotropically directed from the center of the main body portion 10 toward the opening direction. When employ | adopting the structure which concerns, it can provide so that it may have a wall surface in a flow-path direction, without interrupting the warm air W from the warm air heating apparatus F. FIG. FIG. 3 (e) shows a configuration in which the reinforcing portions 30 in the floor surface direction are provided twice and the reinforcing portions 30 can be divided into two.

It is effective to make the height approximately the same as the height of the top board. In addition, it is possible to store in the kotatsu K by configuring it to be slightly lower than the top plate of the kotatsu K, and it is possible to adjust to the height of the kotatsu K by inserting a spacer in the lower part. The configuration is also effective.

  As shown in FIG. 4B, the hot air intake multi-box 1 according to the present invention can be used as a chair. The drawing shows an example of using a chair with a reduced height as a chair, and shows a state where a child is using a kotatsu K as a chair for watching a TV or the like instead of a backrest. It is a thing. In such an embodiment, it can be used as a chair. However, while the upper surface is a seating surface, it is possible to simultaneously provide a hot air intake mechanism with the front and rear surfaces as openings 11 and 12.

  As shown in FIG.4 (c), the warm air taking-in multi box 1 which concerns on this invention can be utilized as a stepping board and a health appliance. That is, the multi-box 1 for taking in hot air according to the present invention employs a configuration having strength that can withstand even if a user rides on the upper surface of the main body 10 by the reinforcing portion 30. The lower one can be used as a stepping board when taking out luggage or the like at high places. When used as a step, it is preferable that the height is kept low, the step per step is low, and a safe step that is easy to ascend. Moreover, as shown in FIG.4 (c), the utilization aspect of the structure which ensures height is also possible as a step of a type | mold which has a level | step difference by combining two or more. In addition, it can also be utilized as a health appliance suitable for exercise of the lower body by repeatedly going up and down the step.
