Description

  The present invention relates to an aroma set and an aroma liquid transpiration method.

  Traditionally, scents are diffused in everyday living spaces, such as a room at home or in the bathroom, to enjoy the scent itself, but also to relax the user and provide a place for mental healing in everyday life. Various aroma goods related to aromatherapy are provided.

  As such aroma goods, for example, incense burners and aroma candles that diffuse the scent using fire, sprays that atomize and vaporize the aroma components in the air, aroma diffuser that makes the aroma components mist with ultrasonic power Aroma sets that vaporize aroma components using a chemical heat source such as an exothermic agent that reacts with water and generates heat are provided.

  In particular, as an aroma set using a chemical heat source, an aroma liquid containing water and aroma components is directly added to the exothermic agent disposed at the bottom of the aroma pot container, and the aroma liquid is removed by the reaction heat generated by the exothermic agent. An aroma set using an aroma pot configured to vaporize an aromatic component by heating (for example, Patent Document 1), or a hot water vapor generated by the reaction between water and a heat generating agent is convected into the aroma pot to obtain an aroma pot. There has been proposed an aroma set (for example, Patent Document 2) using an aroma pot configured to volatilize aroma components by indirectly heating the aroma liquid stored in the upper part of the container.

  According to the aroma set using these chemical heat sources, it is safe to use no fire at the time of use, easy to carry, easy to carry, and less expensive to manufacture. In terms of sex, it is superior to other styles of aroma goods.

Japanese Patent No. 4293746 JP 2008-119105 A

  However, the aroma pot in which the aroma liquid containing water and fragrance components is directly added to the exothermic agent to evaporate, most of the fragrance components contained in the aroma liquid evaporate in a short time from the start of the thermal reaction between water and the exothermic agent. As a result, the fragrance component did not last long and the scent could not be enjoyed without worrying about time.

  In order to solve these problems, a method of adjusting the volatilization amount of the aroma component by controlling the calorific value by mixing other materials with the exothermic agent has been proposed, but an aroma using such an exothermic agent is also proposed. The set is not preferable from an economical viewpoint.

  In addition, the aroma set configured to indirectly heat and volatilize aroma components stored in the upper part of the aroma pot via hot water vapor generated by the reaction between the exothermic agent and water, the room fragrance can be used without worrying about time. Although it can be enjoyed, there is a problem that the time and amount of vaporization required for volatilization of the aromatic component of the aroma liquid due to steam heat are not constant and the scent cannot be diffused quickly.

  In addition, once the aroma set using a heat generating agent is used, even if the aroma liquid containing water or the addition of water is interrupted, the heat generating agent absorbs moisture in the air and continues to deteriorate. Therefore, it takes time and effort to replace the exothermic agent in order to repeatedly use the aroma set.

  Therefore, it is preferable that the aroma set using the exothermic agent is a single-use type, but the single-use type aroma set that combines the quick-acting and long-lasting scent of the fragrance in the aroma liquid due to transpiration of the aroma components. In order to produce, costs such as material costs and production costs as a result of the above-described reasons have been one of the factors that have caused users to hesitate to purchase and not spread.

  The present invention has been made in view of such circumstances, and has a mechanism that adjusts the amount of transpiration of the aroma liquid while using a heat generating agent that reacts with water, thereby quickly diffusing aroma components. In addition, it provides an aroma set that can achieve sustainable diffusion of fragrance and can be manufactured at low cost. In addition, a method for transpiration of aroma liquid is also provided.

  In order to solve the above-described conventional problems, in the aroma set according to the present invention, (1) the bottom layer of the bottomed cylindrical pot contains a heat generating agent that generates heat by reacting with water, and further, the aroma liquid is disposed in the upper layer. And laminating a porous body that can be impregnated, and storing the case in a pot for laminating an aroma liquid containing case for injecting the aroma liquid into the porous body on the upper surface of the porous body, Or it was decided to equip it outside the pot separately.

The aroma set according to the present invention is characterized by the following points.
(2) The aroma liquid storage case is placed on the upper surface of the porous body to press the porous body from above through the weight of the aroma liquid storage case.
(3) The porous body is in contact with the entire inner wall of the pot.
(4) The large number of small holes formed in the porous body should have a smaller diameter near the outer periphery of the porous body.
(5) A heat insulating means for preventing heat dissipation is provided on the wall of the pot.
(6) Locking means for locking the porous body in the pot is disposed on the wall of the pot.

  Further, in the aroma liquid transpiration method according to the present invention, (7) the bottom layer of the bottomed cylindrical pot contains a heat generating agent that reacts with water to generate heat, and the upper layer can be impregnated with the aroma liquid. While laminating the porous body, the calorific value of the exothermic agent is increased by a large amount of aromatized liquid at the beginning of dropping, and the calorific value of the exothermic agent is gradually reduced as the dropping aroma liquid is gradually reduced. In the latter part of the dripping, the aroma solution was gradually released while the transpiration occurred quickly.

  According to the aroma set of the present invention, a heating agent that reacts with water to generate heat is stored in the lowermost layer of the bottomed cylindrical pot, and a porous body that can be impregnated with the aroma liquid is further stacked on the upper layer. In addition, in order to laminate an aroma liquid storage case for injecting the aroma liquid into the porous body on the upper surface of the porous body, the case is stored in the pot or separately provided outside the pot, so the injected aroma The aroma liquid that evaporates by delaying the time for the aroma liquid to reach the exothermic agent while suppressing the liquid volume of the aroma liquid flowing down from the porous body as much as possible by holding a certain amount of the liquid in the porous body. On the other hand, after the heat generation of the exothermic agent, the aroma liquid held in a certain amount in the porous body above the exothermic agent can keep the aroma component from evaporating due to the residual heat of the exothermic agent. . Furthermore, it is possible to provide a simple aroma set that is easy to carry and use, and can enjoy aromatherapy immediately without production costs.

  Further, since the aroma liquid storage case is placed on the upper surface of the porous body and the porous body is pressed from above through the weight of the aroma liquid storage case, the porous body is made of flexible material. When formed from a raw material, the lower end surface of the porous body is substantially stretched by the porous body being bent downward from the substantially central portion due to the weight of the aroma liquid storage case, so that the lower end surface of the porous body is approximately When a large number of small holes in the center are expanded to provide an opening fistula and the aroma liquid is impregnated in the porous body, the aroma liquid is removed from the approximate center of the lower end surface of the porous body. It can be dripped quickly in the vicinity.

  Further, since the porous body is in contact with the entire inner wall of the pot, the exothermic agent disposed at a lower position inside the pot while securely holding the injected aroma liquid in the porous body. Can be substantially sealed. In addition, when the hot water vapor containing aroma components generated after the heat generation passes through the small pores of the porous body at the upper position, the aroma liquid is replaced with the aroma liquid held in a certain amount in the small pores of the porous body. While dripping into the exothermic agent, the porous body can be heated from the inside of the porous body to promote volatilization of the aroma component of the aroma liquid and maintain a continuous scent diffusion. Furthermore, when the pot is formed of a material having high thermal conductivity, the aroma liquid held by the heat from the side surface of the pot that is in contact with the porous body can be heated.

  In addition, since a large number of small holes formed in the porous body have smaller diameters in the vicinity of the outer periphery of the porous body, an area in the vicinity of the outer periphery (hereinafter referred to as an outer peripheral area) of the porous body. )), The amount of the aroma liquid that drops and evaporates from the central area (hereinafter referred to as the central area) can be adjusted while holding a certain amount of the aroma liquid. In addition, when the hot water vapor generated by the heat generated by the exothermic agent passes through the central region, the aroma component of the aroma liquid retained in the same region is volatilized to increase the concentration of the aroma component and improve the quick effect of the scent. On the other hand, it is possible to continuously evaporate the aroma component by heating the outer peripheral side vicinity region from the inside of the porous body without changing the amount of the aroma liquid held in the outer peripheral side vicinity region.

  Further, if a heat insulating means for preventing heat dissipation is provided on the wall portion of the pot, the aroma pot can be gripped and moved even when the heat generating agent is generating heat, and the heat inside the pot is also increased. It is possible to maintain the volatilization of the fragrance component due to the heat retaining heat by suppressing the external radiation.

  Further, if a locking means for locking the porous body in the pot is disposed on the wall of the pot, the dead weight of the porous body impregnated with the aroma liquid or the heat generated under the porous body The amount of the aroma liquid retained in the porous body and the aroma liquid dripped from the porous body are prevented by preventing the porous body disposed at a predetermined position in the aroma pot from shifting in the vertical direction due to air expansion accompanying the water vapor. The amount of transpiration of the aroma liquid can be stabilized by making the amount of the liquid constant.

  Further, in the aroma liquid transpiration method according to the present invention, the bottom layer of the bottomed cylindrical pot contains a heat generating agent that reacts with water to generate heat, and the upper layer can be impregnated with the aroma liquid. In the initial stage of dripping, the calorific value of the exothermic agent is increased by a large amount of dripping aroma liquid, and the calorific value of the exothermic agent is decreased with the gradual decrease of the dripping aroma liquid. In the latter part of the dripping process, the aroma liquid was gradually released while the transpiration occurred, and despite the fact that the exothermic agent was used as the heat source for the transpiration, the aroma components were diffused quickly and maintained for a certain period of time. Diffusion is possible.

  The present invention provides a temporal difference in the volatilization amount of the aroma component of the aroma liquid by adjusting the flow rate of the aroma liquid reaching the exothermic agent that is the chemical heat source while using a chemical heat source as the exothermic method. Immediately after the addition of the aroma liquid, the fragrance can be quickly diffused into the air by the rapid transpiration of the fragrance component of the aroma liquid, and the fragrance can be scented by the user without worrying about time by the continuous transpiration of the aroma component. It relates to a simple aroma set that can be enjoyed at low cost.

  In particular, a characteristic of the aroma set according to the present embodiment is that the bottom layer of the bottomed cylindrical pot contains a heat generating agent that generates heat by reacting with water, and the upper layer can be impregnated with the aroma liquid. In order to laminate an aroma liquid containing case for injecting an aroma liquid into the porous body on the upper surface of the porous body, the case is housed in a pot or separately provided outside the pot. It is supposed to be done.

  In addition, the bottom layer of the bottomed cylindrical pot contains a heat generating agent that reacts with water to generate heat, and further, an aroma pot configured by laminating a porous body that can be impregnated with an aroma liquid on the upper layer is a single unit. Even if it is a case, a user can also select the aroma liquid containing a favorite fragrance component and water arbitrarily, and can also use it for the aroma pot.

  Here, the pot body of the aroma pot constituting the aroma set may be formed in a bottomed cylindrical shape with a heat-resistant material that can withstand the reaction heat of about 100 ° C. generated by the heat generating agent. For example, a metal material such as aluminum or steel, or a heat resistant resin material such as polyethylene or polypropylene may be employed.

  The capacity | capacitance of a pot main body should just be a magnitude | size which can accommodate the exothermic agent and porous body which enable the transpiration | evaporation of an aroma component to be effective quickly when using an aroma liquid. For example, if the volume of the pot body is 50 ml to 250 ml, the aroma liquid containing case containing the aroma liquid can be stored inside the aroma pot while being sufficient for rapid and continuous transpiration of the fragrance component, and it has excellent portability. Can be an aroma set.

  Any exothermic agent may be used as long as it reacts with water and generates heat. For example, if calcium oxide is adopted, material costs can be reduced. When calcium oxide is employed as a heat generating agent, it may be a powder or granule having a particle size of 10 mm or less and a calcium oxide content of 90% or more.

  In addition, if such a heat generating agent is housed and sealed in a packaging bag made of a material having heat resistance and water permeability, when the heat generating agent is disposed in the bottom layer of the bottomed cylindrical pot, the heat generating agent is placed inside the pot. The amount of the exothermic agent that reacts with the aroma liquid without being scattered can be made constant.

  The amount of the exothermic agent can be arbitrarily adjusted according to the duration of the exothermic reaction and the amount of water contained in the added aroma liquid. The reaction water added to the exothermic agent may be a capacity that allows the exothermic agent to completely react with water reaching the exothermic agent, taking into account the amount impregnated in the porous body. For example, if the amount of water reaching the heat generating agent is 1 to 2 parts by weight with respect to 1 part by weight of the heat generating agent, the duration can be increased and sufficient reaction heat can be obtained.

  The aroma liquid only needs to contain a volume of water that causes an exothermic reaction in the exothermic agent and an aroma component that is a source of aroma. For example, if the fragrance component contained in the aroma liquid is 40 to 60 v / v%, a sufficient duration can be obtained for the transpiration of the fragrance component and the thermal reaction of the exothermic agent.

  The aroma component contained in the aroma liquid may be anything that volatilizes and emits a fragrance, and may be a synthetic fragrance, a natural fragrance, or a blended fragrance blended with these. In addition, if it is a liquid fragrance | flavor, dilution will become easy. In addition, when an essential oil is selected as an aroma component, it is possible to prevent separation of the aroma component and water by adding an appropriate amount of a surfactant so that the aroma liquid becomes a hydrate of the aroma component and water.

  The aroma liquid storage case for storing the aroma liquid only needs to be configured so that it can be completely sealed by storing the aroma liquid and can be opened when the aroma liquid is injected into the aroma pot. For example, it can be set as the aroma set which accommodated the aroma liquid accommodation case in the aroma pot by comprising in aroma pot with a flexible resin material. Further, when the aroma set is used, the aroma liquid storage case can be pressed to inject the aroma liquid into the aroma pot without excess or deficiency so as not to remain inside the aroma liquid storage case.

  In addition, when the aroma liquid is added from above, the porous body has a heat resistant structure in which a large number of small holes are formed so that the aroma liquid can be dropped from the porous body while maintaining a certain amount of the aroma liquid inside the porous body. Any porous material may be used. For example, pumice, zeolite, non-woven fabric, sponge, or a combination thereof can be used. Moreover, if it is flexible sponge, a melamine material and a polyurethane material are suitable from a heat resistant and economical viewpoint.

  In addition, the large number of small holes formed in the porous body may have a smaller diameter near the outer periphery of the porous body. Specifically, when the porous body is disposed inside the aroma pot, the pores in the vicinity of the outer peripheral side of the porous body have a smaller pore diameter than the pores in the central region of the porous body. You may comprise as follows.

  For example, a plurality of porous bodies having different pore diameters may be combined to each other, and a heat-resistant and flexible porous body formed wider than the pot body in a plan view may be formed on the outer periphery of the porous body. The small holes in the vicinity of the outer peripheral side may be made smaller by arranging them at predetermined positions in the upper and lower parts of the pot body so as to compress the side.

  The size and shape of the porous body is not particularly limited as long as it can hold and drip a certain amount of aroma liquid and can be disposed above the heating element inside the bottomed cylindrical pot. .

  The heat insulation means can insulate the user so that the user can grip the aroma pot, and further suppress the heat radiation from the inside of the pot to the outside as much as possible, and the residual heat generated inside the aroma pot even after the heat reaction of the exothermic agent is completed. If you can keep warm. For example, the aroma pot main body may have a double wall structure, or a sheet type heat insulating material such as a foam sheet may be attached to the aroma pot wall surface.

  As the heat insulating material, fiber-based heat insulating materials such as glass wool and rock wool, foam-based heat insulating materials such as urethane foam, phenol foam, polystyrene foam and foam rubber, or a composite selected from these groups, such as aluminum or It may be combined with a heat shielding material such as ceramic.

  In addition, if a removable heat insulating cover covering the outer periphery of the aroma pot is provided as a separate body as a heat insulating means, the user can arbitrarily select a heat insulating cover with various designs, and the aroma. It is possible to consider the environment without discarding the insulation cover every time the set is used.

  The porous body locking means may be configured so that a predetermined amount of aroma liquid can be locked at a predetermined position inside the pot where the porous body can hold or drip. For example, as described above, the porous body having heat resistance and flexibility formed wider than the pot body in plan view is compressed by placing the outer peripheral side of the porous body at a predetermined position above and below the pot body. The porous body may be locked at the arrangement position by elastic stress so as to expand. Further, a partition plate that supports the lower end surface and the upper end surface of the disposed porous body from above and below may be provided on the peripheral surface of the inner wall of the aroma pot, and the outer wall surface of the aroma pot may be provided along the position where the porous body is disposed. Alternatively, the porous body may be sandwiched and locked while being recessed.

[Example 1]
Hereinafter, the aroma set according to the first embodiment will be described with reference to the drawings. FIG. 1 is an explanatory diagram illustrating a use state of an aroma set A including an aroma pot 10 according to the first embodiment.

  The aroma set A enables aromatherapy by evaporating the aroma component F by adding the aroma liquid 51 accommodated in the aroma liquid accommodating case 50 by the user P from the upper opening 25 of the aroma pot 10.

  As a heat insulating means, a bottomed cylindrical heat insulating cover 60 having a design on the outer periphery is attached to the aroma pot 10, and encloses the outer periphery of the aroma pot 10 in a heated state.

  FIG. 2 is a longitudinal cross-sectional view illustrating the configuration of the aroma set A according to the first embodiment. That is, the bottom layer of the bottomed cylindrical pot body 20 contains the heat generating agent 31 that generates heat by reacting with water, and further laminates the porous body 40 that can be impregnated with the aroma liquid 51 on the upper layer, In order to laminate an aroma liquid storage case 50 for injecting the aroma liquid 51 into the porous body on the upper surface of the porous body, the aroma set A is stored in the aroma pot 10.

  More specifically, in the aroma set A, a heating element 30 that reacts with water to generate heat is disposed on the inner bottom surface of the bottomed cylindrical pot body 20 having the upper opening 25, and the upper position of the heating element 30 An aroma liquid containing case 50 containing the aroma liquid 51 is placed on the upper end surface of the porous body 40 inside the aroma pot 10 in the aroma pot 10 configured by disposing the porous body 40 impregnated with the aroma liquid 51. Configured.

  The aroma pot 10 is configured by dividing the internal space into three stages in the vertical direction. The space at the lower stage is a heating element housing space S3, and the heating element 30 is disposed at the bottom of the pot body 20. The space in the middle position is a porous body arrangement space S2, and is arranged so that the outer peripheral side surface of the porous body 40 is in close contact with the inner peripheral wall surface of the pot body 20 at a predetermined position. The upper position is the rectifying space S1, which functions to guide the aroma generated inside the aroma pot 10 to the upper side of the aroma pot 10 and also functions as a space for storing the aroma liquid storage case 50.

  The pot body 20 is made of a heat-resistant steel material and has a bottomed cylindrical shape having an upper opening 25. A porous body 40 that is impregnated with the aroma liquid 51 is disposed in a substantially vertical central portion of the pot body 20, that is, in the porous body arrangement space S <b> 2 at the middle position of the pot body 20. Further, the disposed porous body 40 partitions the inside of the pot body 20 with the rectifying space S1 above the porous body 40 and the heating element accommodating space S3 below the porous body 40, respectively.

  The porous body 40 is a sponge made of a polyurethane material having heat resistance and flexibility, and the outer peripheral side wall of the porous body 40 is formed in a cylindrical shape that can be crimped to the inner peripheral wall of the substantially central portion in the vertical direction of the pot body 20. Yes. Specifically, the diameter of the porous body 40 is formed wider than the diameter of the pot body 20, and when the porous body 40 is disposed in the pot body 20, the outer peripheral side wall of the porous body 40 is the pot body 20. The porous body 40 is locked and fixed to the substantially central portion of the pot body 20 in the vertical direction.

  In such a pressure-bonded state, a large number of small holes formed in the porous body 40 are compressed toward the outer peripheral side to form a small-diameter mouth, and the porous body 40 includes a central region M at a substantially central position in plan view and a central portion. A two-layer region is formed with an outer peripheral side vicinity region O in the vicinity of the outer peripheral side, which has a smaller diameter opening than the small hole of the partial region M.

  The central region M of the porous body 40 functions as a central portion where the aroma liquid 51 impregnated in the porous body 40 moves down inside the porous body 40 and is dropped onto the heating element 30, and the heat of the heating element 30. Serves as a region through which the hot water vapor generated by heating the aroma liquid 51 passes upward.

  Further, the outer peripheral side vicinity region O of the porous body 40 is a region in which the flow rate of the aroma liquid 51 inside the porous body 40 is delayed as compared with the central region M and the aroma liquid 51 is held in the porous body 40. Function as.

  In the bottom of the pot body 20, that is, the heating element housing space S3, a heating agent 31 that is calcium oxide particles that generate heat by reacting with water is laminated to form a heating element 30.

  In addition to the heating element 30, a convection space S4 that is a predetermined gap space is formed in the heating element housing space S3 in the lower stage of the pot body 20 due to the arrangement of the heating element 30. That is, a convection space S4 is formed between the upper end surface of the heating element 30 and the lower end surface of the porous body 40.

  In the convection space S4, the lower end surface of the porous body 40 and the upper end surface of the heating element 30 are in close contact with each other, and the heating element 30 excessively absorbs the aroma liquid 51 impregnated in the porous body 40 and becomes overheated. The amount of dripping of the aroma liquid 51 reaching the heating element 30 is kept constant to stabilize the exothermic reaction, and also functions as a space in which the hot water vapor generated from the heating element 30 convects.

  The aroma liquid storage case 50 for storing the aroma liquid 51 in which water and the fragrance component F are mixed is composed of a flexible resin container body and a cap of the attachment / detachment itself. And is closed with a cap.

  In the unused aroma set A, the aroma solution containing case 50 containing the aroma solution 51 is placed on the rectifying space S1 in the upper position of the aroma pot 10 configured as described above, that is, the upper end surface of the porous body 40. The upper opening 25 of the aroma pot 10 is closed with the pot lid 23, and the entire periphery of the aroma set A is wrapped with a film 24 and attached to prevent the heating element 30 from aging. Sealed.

  When using the aroma set A, the aroma pot 10 is provided so that the upper opening 25 of the aroma pot 10 is not blocked by a heat insulating cover 60 (see FIG. 1) formed as a separate bottomed cylinder provided separately. Is attached and the outer periphery of the aroma pot 10 is encapsulated by a heat insulating cover 60, so that the heat inside the reaction heat generated inside the aroma pot 10 and the heat insulation through the outer peripheral wall are performed.

  Next, the state change of the aroma liquid 51 inside the aroma pot 10 when the aroma set A is used will be described with reference to FIG. FIG. 3 is an explanatory view showing a longitudinal section of the aroma pot 10. 3A shows a state immediately after the aroma liquid 51 is added to the aroma pot 10, and FIG. 3B shows that the added aroma liquid 51 penetrates into the porous body 40 and drops. It shows the state that started.

  Further, in the aroma set A according to the present embodiment, the transpiration mechanism of the aroma liquid 51 is large, and the initial stage of the thermal reaction start immediately after the addition of the aroma liquid 51 shown in FIG. 3-1 (c) is shown in FIG. It is divided into the middle stage shown in FIG. 3-2 (e) and the latter stage after the end of the thermal reaction after the aroma liquid 51 is added.

  The penetration of the aroma liquid 51 into the porous body 40 is performed by replacing the small holes of the porous body 40 with the aroma liquid 51 from the gas. As shown in FIG. 3A, the aroma liquid 51 immediately after being added from the upper opening 25 is stored on the upper end surface of the porous body 40 and gradually infiltrates into the porous body 40. . That is, the aroma liquid 51 penetrates into the porous body 40 from the central region M and then from the outer peripheral side region O in the upper end surface of the porous body 40.

  And the aroma liquid 51 which permeated from the upper end surface of the porous body 40 flows down the center part area | region M inside the porous body 40, as shown in FIG. While infiltrating into the adjacent outer peripheral region O side.

  As described above, the porous body 40 is in a swollen state by substituting the small holes over substantially the entire area of the porous body 40 with the aroma liquid 51, so that the outer peripheral side surface of the porous body 40 and the inner peripheral wall surface of the aroma pot 10 are more closely attached. Then, the heating element 30 and the convection space S4 are substantially sealed upward.

  Then, in the porous body 40 in the swollen state, the aroma liquid 51 flowing down inside the porous body 40 due to the weight of the held aroma liquid 51 and the porous body 40 out of the added aroma liquid 51 become supersaturated. As shown in FIGS. 3-1 (b) and 3-1 (c), the aroma liquid 51 oozes out from the lower end surface of the central region M of the porous body 40 and starts dripping into the convection space S4. Reaction heat is generated by reaching the upper end surface of the heating element 30 and infiltrating the heating agent 31.

  Due to this heat of reaction, the aroma liquid 51 infiltrated into the heating element 30 is heated and evaporated to produce hot water vapor containing the fragrance component F1 (FIG. 3-1 (c), dotted arrow).

  This hot water vapor is convected inside the convection space S4 to increase the internal pressure of the heating element housing space S3 while keeping the heating element housing space S3 in a high temperature state, and from the lower end surface of the central region M of the porous body 40 to the porous body. 40 Move up inside.

  The aroma liquid 51 held in the small holes in the porous body 40 is released from the small holes by the biasing force that the hot water vapor passes through the central area M in the porous body 40 and passes through the central areas. The exothermic reaction is sustained by moving downward to the M lower end surface side and dropping onto the heating element 30.

  On the other hand, the retained aroma liquid 51 is heated and evaporated by the heat of the hot water vapor passing through the small holes inside the porous body 40. For this reason, the fragrance component F2 (FIG. 3-1 (c), solid line arrow) evaporated to the upper part of the aroma pot 10 through the porous body 40 is the fragrance component F1 contained in the hot water vapor convected to the convection space S4. The concentration is higher than the concentration.

  Thus, in the initial stage immediately after the addition of the aroma liquid 51, a large amount of the aroma liquid 51 is dripped to increase the heat generation amount of the heat generating agent 31, and the fragrance component F2 in a high concentration state is evaporated. For this reason, the fragrance component F2 guided by the rectifying space S1 can be diffused into the air as quickly as possible, and the use space of the aroma set A can be filled with fragrance.

  Next, the middle stage of the thermal reaction sustained state after adding the aroma liquid 51 will be described. As shown in FIG. 3-2 (d), the state of the porous body 40 in this intermediate stage is that the upper part retains the air layer in which the aroma liquid 51 is replaced with hot water vapor or air, and the lower part flows down the aroma liquid 51. This is a state in which the aroma liquid 51 that becomes a layer and drops on the heating element 30 is reduced from the initial stage.

  Specifically, as the small holes of the porous body 40 are gradually replaced with air or hot water vapor from the upper side of the central region M by the flow or evaporation of the aroma liquid 51 held in the porous body 40, The aroma solution 51 held in the side vicinity region O infiltrates the center region M so as to replenish the aroma solution 51, and flows down through the center region M to maintain the holding layer of the aroma solution 51.

  In addition, as the holding layer of the aroma liquid 51 of the porous body 40 is gradually thinned with the flow and evaporation described above, the amount of the aroma liquid 51 dripped onto the heating element 30 is decreased, The amount of hot steam generated is reduced.

  Then, the normal concentration fragrance component F1 and the high concentration fragrance component F2 are mixedly released from the aroma pot 10 in the middle stage of the heat reaction sustained state after the addition of the aroma liquid 51. That is, as in the initial stage immediately after the addition of the aroma liquid 51, the aroma component of the aroma liquid 51 held when passing through the central region M inside the porous body 40 is volatilized to aroma component F2 in a high concentration state. Is released and the aroma liquid 51 held in the porous body 40 is heated and evaporated by the heat of the hot water vapor convected in the convection space S4 below the porous body 40, whereby the aromatic component F1 having a normal concentration is obtained. Released.

  The release amount of the high-concentration fragrance component F2 decreases with time, and the total release amount of the fragrance components of the normal-concentration fragrance component F1 and the high-concentration fragrance component F2 decreases.

  As described above, in the middle stage after the addition of the aroma liquid 51, as the amount of the aroma liquid 51 that reacts with the heating element 30 decreases, the concentration of the fragrance component continues to decrease while the discharge amount decreases. Release is possible.

  Next, the latter stage after completion of the thermal reaction after the addition of the aroma liquid 51 is a state after the heating element 30 has reacted with the water contained in the aroma liquid 51 as shown in FIG. 3-2 (e). That is, in the middle stage after the addition of the aroma liquid 51 described above, transpiration of the high-concentration aromatic component F2 is not performed.

  More specifically, of the aroma liquid 51 held inside the porous body 40, the aroma liquid 51 that can be dropped onto the heating element 30 is dropped at the initial stage and the middle stage to cause an exothermic reaction with the heating element 30. At the end, the remaining hot water vapor is convected in the convection space S4.

  The heat generating body accommodation space S3 is kept warm by the heat of the convection hot water vapor and the residual heat of the heat generating agent 31, and the remaining aroma liquid 51 held in the porous body 40 is evaporated by heating. More specifically, the heat retaining heat in the heating element housing space S3 is transmitted to the inner peripheral wall of the porous body arrangement space S2 of the pot body 20, and is porous from the outer periphery side of the porous body 40 and from the lower end surface side of the porous body 40. The remaining aroma liquid 51 retained in the outer peripheral side vicinity region O in the mass 40 is heated, and the aroma component F1 having a normal concentration is gradually released from the aroma pot 10.

  As described above, the aroma pot 10 in the later stage after the addition of the aroma liquid 51 further releases a gentle scent in the air by reducing the amount of released aroma components more than in the initial stage and the middle stage.

  Next, with reference to FIG. 4, the amount and time of release of the fragrance component into the air when using the aroma set A will be described. The vertical axis represents the amount of fragrance component released into the air, and the horizontal axis represents the fragrance component release time. In addition, symbols (a) to (e) in FIG. 4 indicate the use of the aroma set A shown in FIGS. 3-1 (a) to (c) and FIGS. 3-2 (d) to (e), respectively. It corresponds to the state.

  In FIG. 4, in the initial stage of the start of the thermal reaction immediately after the addition of the aroma liquid 51, the amount of the aroma liquid 51 dropped onto the heat generating agent 31 is increased to increase the heat generation amount of the heat generating agent 31, as shown in FIG. In addition, the high-concentration fragrance component F2 rises in a short time, and transpiration continues for a certain period of time with the amount released being maximized.

  Then, as shown in (d), in the middle stage of the heat reaction sustained state after the addition of the aroma liquid 51, the released amount of the aroma component gradually decreases, and as shown in (e), the heat after the addition of the aroma liquid 51. In the later stage after the completion of the reaction, the amount of the fragrance component released is further reduced to enable sustained release of the fragrance component.

  On the inner peripheral surface of the pot main body 20, an upper partition plate 21 and a lower partition plate 22 formed in a donut shape in plan view as locking means for the porous body 40 are vertically separated with a predetermined interval in the pot body 20 longitudinal direction. It is connected to the position horizontally.

  More specifically, an upper partition plate 21 that is convex at an upper position in the vicinity of the substantially central portion in the vertical direction of the pot body 20, and a lower portion with an interval so as to be approximately the same length as the height of the porous body 40. A convex lower partition plate 22 extending longer than the upper partition plate 21 is provided at a position so as to protrude horizontally from the inner wall peripheral surface of the pot body 20, and between the upper partition plate 21 and the lower partition plate 22. The porous body 40 can be fitted.
