Description

  The present invention relates to a dry warming device for a hot pack used for thermotherapy.

A hot pack is a hot compress, and is used for thermotherapy because it can be expected to improve blood circulation by affixing it to a joint or the like and suppress inflammation, stiffness, pain, and the like.
The hot pack generally contains a heat insulating agent containing silica gel in a cloth bag, etc., stored in a warm storage room, taken out from the warm storage room and wrapped in a dry bath towel to prevent heat dissipation, The treatment is performed by warming up the required time (Patent Document 1).

The above hot storage is generally a hot water tank (storage). When a hot pack is taken out from the hot water, if water drops adhere to the surface of the hot pack, the water drops adhere to the bath towel, which is inconvenient for the patient. In order to give a pleasant feeling, it is necessary to wipe off the water droplets.
For this reason, dry-type hot pack heating devices have been developed that imitate a storage room for storing food and the like as disclosed in Patent Documents 2 and 3.

Japanese Utility Model Publication No. 61-57919 JP 2000-287850 A JP 2001-269249 A

However, since the conventional heating device for dry hot packs is provided with heaters only on both side walls of the hot storage, the temperature distribution in the storage is uneven, and the hot pack stored in the storage In addition to being unable to uniformly heat all of the above, there is a problem that the heating takes time. In particular, when the hot pack capacity is increased, the problem becomes more prominent.
Further, when the capacity of the hot pack is increased, the heating capability is naturally increased, and the outer peripheral surface of the heating device is also heated by the transfer of the internal heat. When the outer peripheral surface is heated, if the degree of heating is large (too much), when the outer periphery, particularly the outer surface, is touched, the touched person is uncomfortable.

  In view of the above situation, the present invention provides a dry-type heating device that uniformly heats all of the contained hot packs and that can perform the heating smoothly. It is a second problem to suppress the heating of the.

In order to achieve the first object, according to the present invention, if the capacity of the hot pack is increased, it is necessary to increase the output of the heater for heating. In addition to the both side walls of the conventional warmer, the heater for heating is also provided on the bottom wall of the warmer and its partition member.
In this way, if a heater is provided on the bottom wall and the partition member, the hot pack around the bottom wall and the partition wall of the warm storage can be warmed. Therefore, compared to the case where the heater is provided only on the side wall, the warm storage is Even if the storage amount of the hot pack is increased, all of the stored hot packs can be uniformly heated and the heating can be performed smoothly.
In other words, the hot pack near the bottom surface is heated by the bottom wall heater, and the hot air rises and stays in the upper part of the warehouse, so that the hot pack in the upper part of the warehouse is also appropriately heated. The hot pack that is positioned is hard to be heated sufficiently only by passing hot air. For this reason, a heater is also provided in the partition member.

  As a configuration of the present invention, the inside of the heating box made of a heat insulating box is divided into a plurality of partitions by a partition member, heaters are arranged on both side walls, the bottom wall and the partition member of the heating chamber, and the top surface and the partition of the bottom wall It is possible to adopt a configuration in which a hot pack is placed on the upper surface of the member and the hot pack is heated by energizing the heater.

In this configuration, the number of partition members is arbitrary as one, two, or more, and the interval (distance) is also appropriately determined by experiments or the like in consideration of the internal capacity and the heating temperature.
Each heater is preferably provided on the entire side wall, bottom wall, and partition member, but is appropriately determined in consideration of a range in which the heater can be installed, a hot pack placement range, and the like. Moreover, the thing of various aspects, such as linear shapes, such as a nichrome wire, and planar shapes, such as carbon and aluminum, is employable as the heater.

The output of each heater may be the same, but the heating mode by each heater differs depending on the shape of the heating chamber, for example, the vertical rectangular parallelepiped, horizontal rectangular parallelepiped, rectangular parallelepiped, etc. and hot pack storage mode, and the heating chamber of the vertical rectangular parallelepiped In this case, it is preferable that at least the output of the heater of the partition member is smaller than the output of the heater of the both side walls and / or the bottom wall, and further, the heater of the partition member, the heater of the bottom wall, the both side walls It is more preferable to increase the output in the order of the heaters. Since the heater on the side wall faces the entire area in the warehouse and heats the entire area, it is preferable that the heater on the side wall has a large output. When the capacity of the bottom wall heater is increased, The entire interior, especially the bottom, cannot be heated sufficiently, so it is necessary for auxiliary heating. However, since it is heated from the bottom, low output is sufficient compared to the heater on the side wall. .
In addition, as described above, the hot pack located at the intermediate part in the warehouse is not heated sufficiently only by passing hot air, so the partition member is also provided with a heater. Since it assists heating by the heater on the bottom wall, the output can be reduced compared to them.

On the other hand, in the case of a horizontally long rectangular parallelepiped heating chamber, the area of the side wall is reduced, and the area of the bottom wall and partition member is increased. At this time, for the above reason, the output of the heater of the partition member is made smaller than the output of the heater of the bottom wall.
However, regardless of the shape of the heating chamber such as a vertically long rectangular parallelepiped or a horizontally long rectangular parallelepiped, when the partition member is provided in the vertical direction, the output of the heater of the partition member may be increased relative to the output of the heater on the bottom wall. Conceivable.
In this way, by varying the output of the heater at the installation location, it is possible to uniformly heat all the hot packs stored with appropriate electric power and to smoothly perform the heating. It also saves energy. The output of each heater is appropriately determined by experiments or the like.

Furthermore, in these configurations, when the door of the heating chamber is fastened, the hot air rises between the inner surface of the door and the front surface of the partition member from the interior below the partition member to the upper compartment. It is preferable to provide a gap.
As described above, the hot air is circulated from the lower side to the upper side through the ventilation gap, so that the entire area inside the box is uniformly heated.
Incidentally, in a food storage cabinet, hot air is forcibly circulated by a fan or the like (Patent Document 3), but the hot pack is wrapped in a bath towel or applied to the affected area as described above. Various kinds of dust such as dust adhere, and the dust is scattered in the forced circulation flow and scattered in the cabinet, and there are inconveniences such as collecting in the corners and burning with heat. If so, there is little fear.

Next, in order to achieve the second problem, the present invention provides a heating chamber of a heating device, an outer box, a heat insulating layer on the inner surface of the outer box, an inner box on the inner surface of the heat insulating layer, The air passage in the vertical direction is formed between the side wall of the outer packaging box and the side wall of the heat insulating material layer, and the lower end of the air passage is opened on the outer surface of the outer packaging box and the upper end thereof is opened on the outer surface of the outer packaging box. It is.
In this way, if a vertical air passage is formed between the outer box of the heating cabinet and the heat insulating material layer, the hot air is directed from the bottom to the top. It enters from the opening, flows upward, and flows out from the upper end opening. The outer box is cooled by this air flow. For this reason, unlike the conventional case, the outer box is not excessively heated, and even if the outer surface is touched, the touched person is less likely to be uncomfortable.

As a specific configuration of the present invention, a heater is disposed in a heating box made of a heat insulating box for storing a hot pack, and the hot pack is heated by energizing the heater. In the apparatus, the heating chamber is composed of an outer box, a heat insulating layer on the inner surface of the outer box, and an inner box on the inner surface of the heat insulating layer, and between the side wall of the outer box and the heat insulating layer. It is possible to adopt a configuration in which a vertical air passage is formed, the lower end of the air passage is opened to the outer surface of the outer box, and the upper end is opened to the outer surface of the outer box.
In this configuration, the length of the ventilation path in the vertical direction may be set as appropriate so that a desired cooling effect can be obtained by experiments or the like. If it is further extended, the heat transmitted from the inside of the cabinet can be effectively released.
These exterior box cooling configurations can be used in combination with the configuration of the invention that can achieve the first problem.
In addition, although the positional relationship between the heat insulating material layer and the air passage can be reversed (the air passage is inside), in this case, the side wall heater and the interior are easily cooled by the air flow, so that sufficient heating capability is exhibited. Can't be done. That is, like this structure, the exterior box, the ventilation path, the heat insulating material layer, and the aspect in the warehouse are preferable as a heating cabinet.

In the present invention, as described above, since heating is performed from the side surface, bottom surface, and intermediate portion in the heating chamber, all of the hot packs that are accommodated are uniformly heated, and the warming is smoothly performed. You can do it.
Further, since the side face (side wall) of the outer box is cooled by the air passage, the side face of the outer box is not excessively heated.

Embodiment 1

  1 to 6 show an embodiment of a warming device according to the present invention. The warming device of this embodiment includes a vertically long rectangular parallelepiped warming chamber 1 having an internal capacity of 162 L and its door 2. Casters 3 are provided at the four corners of the lower surface of the heating chamber 1 and can be moved via the casters 3, and lock screw legs 4 are provided at the four corners to prevent (fix) the movement with the screws. Is done.

The heating chamber 1 is a heat insulating box whose inner and outer surfaces are made of stainless steel plates and in which a heat insulating material layer is provided between the two stainless steel plates (see FIGS. 7 to 9). The upper and lower compartments are respectively provided with cages 6a and 6a, and the cages 6b and 6b are also provided on the top and bottom surfaces of the middle plate 5, respectively. Each car 6a, 6b can be pulled out on the rail 7 with a handle 7a. For example, as shown in FIG. 3, the former car 6a accommodates the hot pack P in a horizontal position, and the latter car 6b is partitioned by three partition frames 8 in the left-right direction, as shown in FIG. In addition, the hot pack P is placed vertically.
Each of the cars 6a and 6b is preferably coated with a heat resistant resin to enhance the heat resistance. In the figure, 5a is a middle plate front cover, and 5b is a middle plate support.

Surface heaters 9a, 9a, 9b, 9c made of aluminum foil, carbon, or the like are built in almost the entire surfaces of the side walls 1a, 1a, the bottom wall 1b, and the intermediate plate 5 of the heating chamber 1. For example, the output of the side wall heater 9a is set to 178 W, the bottom wall heater 9 b is set to 147 W, and the middle plate heater 9 c is set to 107 W.
Thus, since the side wall heater 9a reaches the whole area in the warehouse 1 and heats over the whole area, it is set as a large output, and the bottom wall heater 9b increases the capacity in the warehouse 1 (for example, 100L → 162L), since the side wall heater 9a cannot sufficiently heat, it is installed for auxiliary heating and only the bottom surface, so that the output is lower than that of the side wall heater 9a.
Furthermore, since the hot pack P located at the intermediate portion in the refrigerator is not easily heated by only passing hot air a, the hot pack P in the central portion of the refrigerator is heated by the intermediate plate heater 9c. Since the heating assists the heating by the side wall and bottom wall heaters 9a and 9b, if the output is smaller than those, it is accommodated in the heating chamber 1 with appropriate power. While heating all the hot packs P uniformly, the heating can be performed smoothly. At this time, as shown in FIGS. 1 and 3, both ends of the middle plate heater 9c are retracted by a required length from the inner surface of the side wall to prevent overheating by the heaters 9a and 9c in the retracted portion. The amount of retreat is set appropriately by experiment. As described above, it is preferable that one heater end is appropriately retracted in a portion where the heaters 9a, 9b, and 9c face each other in consideration of the heating temperature.

Further, since the middle plate 5 has a plate shape in which the entire surface is closed, its front end surface is retracted by about 30 mm, and when the door 2 is tightened, there is a gap between the inner surface of the door 2 and the front end surface of the middle plate 5. A gap t is formed, and a path in which hot air a rises from the inside of the lower compartment to the upper compartment is formed, and the inside temperature is made uniform by this ventilation (hot air a) (see FIG. 2). .
Further, a total of four temperature sensors S are provided between the upper and lower cages 6a and 6b on the upper side of the middle plate 5 in the heating chamber 1 and between the upper and lower cages 6a and 6b on the lower side (FIG. 3). See). The number and location of the temperature sensors S are set as appropriate through experiments. The installation depth of each sensor S is about 388 mm from the front surface of the heating chamber 1 in this embodiment.

  Based on the measured values of these temperature sensors S, energization to each of the heaters 9a, 9a, 9b, 9c is separately turned on / off, and the inside of the heating chamber 1 is controlled to an appropriate temperature. In addition, bimetal, thermostat, and thermistor are installed (incorporated) at appropriate locations in the cabinet and the control circuit, and based on the detected value, energization to each heater 9a, 9a, 9b, 9c is stopped to prevent overheating. . Thus, by having a plurality of overheating prevention means, for example, even if one prevention means (for example, a thermostat) fails, abnormal overheating is appropriately prevented by other prevention means (thermistor, etc.).

An operation panel T is provided on the upper front surface of the heating chamber 1, and the operation panel T includes a weekly timer setting unit 20, a temperature setting unit 30, and an operation setting unit 40 as shown in FIG. 4.
The weekly timer setting unit 20 includes a diode lamp 21 representing each day of the week, a time / setting display liquid crystal plate 22, a setting button (key) 23, an operation button (key) 24 (24a, 24b, 24c, 24d, 24e), and each setting. Each has an item display diode lamp 25 (25a, 25b, 25c).

As for the operation of the weekly timer setting unit 20, “current time” is normally displayed on the time / setting display liquid crystal plate 22, and when the setting button 23 is turned on (pressed) as shown in FIG. When the mode is on and the same length is on (for example, when pressed for about 5 seconds), the time setting mode is set. When the setting button 23 is turned on again, the current time display is restored.
“Day selection” in the “weekly timer setting mode” is such that when the operation buttons 24a and 24b are turned on, the setting item display diode lamps 25a, 25b and 25c are turned on one after another. Therefore, when the day display diode lamp 25a is turned on, the setting button 24e is turned on to confirm “select day”. After confirming, each day of the week is changed by sequentially turning on the operation buttons 24a and 24b (button 24a: month->fire->water->, button 24b: month->day->soil->), By turning on the setting button 24e, the day of the week is determined. As a result of this determination, the mode shifts to “start time setting / end time setting mode”.

  When the "start time setting / end time setting mode" is entered, the start time display diode lamp 25b is turned on, and the operation buttons 24a and 24b are turned on to switch between "hour setting" and "minute setting". When the buttons 24c and 24d are turned on, the time of “hour” and “minute” is changed, and when the setting button 24e is turned on, the “hour” and “minute” are determined. As a result of this determination, the process proceeds to the “end time setting mode”, and similarly, the end time “hour” and “minute” are set.

  “Day selection” in the “time (current time) setting mode” indicates that all the setting item display diode lamps 25 (25a, 25b, 25c) are turned off, and the operation buttons 24a, 24b are sequentially turned on in the same manner as described above. Each day of the week is changed by turning on, and the day of the week is determined by turning on the setting button 24e. With this confirmation, the mode shifts to the “time setting mode”. The “time setting” is performed in the same manner as the “start time setting” or “end time setting”.

  The temperature setting unit 30 includes “summer” and “winter” mode display diode lamps 31a and 31b, a chamber temperature / set temperature display liquid crystal plate 32, a setting button 33, operation buttons (keys) 34 (34a and 34b), a heater, Each has an error and door opening display diode lamp 35 (35a, 35b, 35c). “Spring (Autumn)” mode can be added.

  In this temperature setting unit 30, the left liquid crystal plate 32 displays the current internal temperature, the right liquid crystal plate 32 displays the set temperature, and the operation of the temperature setting unit 30 is shown in FIGS. 6 (a) and 6 (b). Is performed as shown in FIG. That is, as shown in FIG. 6A, when the heater 9 is energized, the heater display lamp 35a is turned on, and when an error occurs, the error display lamp 35b is turned on and the left liquid crystal plate 32 is A number indicating the error content is displayed. The error display is canceled when the setting button 33 is turned on (pressed). When the door 2 is opened, the door opening display lamp 35c is turned on. When this lighting time (door opening time) exceeds a certain time, for example, 2 minutes, an alarm sound is emitted.

  As shown in FIG. 4B, the internal temperature setting is switched from lighting to blinking when the setting mode button 31 of “summer” or “winter” is turned on. Thereafter, when the setting button 33 is turned on, the “set temperature” of the right liquid crystal plate 32 blinks, and the temperature is set by turning on the operation button 34a or 34b. By turning on the setting button 33, the set temperature is determined. On the way, when the “summer” or “winter” setting mode button 31 is turned on again, the setting is canceled and the display is switched to the seasonal mode display.

  The operation setting unit 40 includes a setting button 41 and a display diode lamp 42 for “continuous operation” and “weekly timer operation”. During continuous operation, the lamp 42 is turned on, the weekly timer operation display lamp 42 is turned off, and the weekly timer operation is performed. The lamp 42 is turned on, the continuous operation display lamp 42 is turned off, and the lamps 42 and 42 are turned off. “Continuous operation”, “weekly timer operation”, and “stop” are switched by pressing (turning on) the setting button 41.

  This embodiment has the above-described configuration, and Table 1 below shows the temperature ° C measured at each of the measurement points (1) to (13) in Fig. 3 when a paraffinic heat insulating agent is used for the hot pack P. In the table, HP indicates hot pack P.

  From this Table 1, in this Embodiment 1, the paraffinic heat insulating agent becomes liquid when it exceeds 60 ° C., and each hot pack P can be used. Thus, it can be understood that the entire inside of the heating chamber 1 is heated substantially uniformly, and all of the stored hot packs P are heated substantially uniformly, and the heating can be performed smoothly. Note that the flow of hot air a in the warehouse differs depending on the placement mode of the hot pack P. For example, in the vertical placement, heat (hot air a) tends to be trapped in the hot pack P compared to the horizontal placement, and the temperature tends to be high.

Embodiment 2

In the said Embodiment 1, the outer surface temperature of the side walls 1a and 1a of the heating chamber 1 may become 55 degree | times or more, and when a person touched the outer surface, I felt discomfort. For this reason, this Embodiment 2 has suppressed the temperature rise of the outer surface in Embodiment 1, and as shown in FIGS. 7-9, in the heating chamber 1 like the said Embodiment 1. FIG. The outer surface is made of a stainless steel plate, and the heating chamber 1 is made up of an outer packaging box 11 made of the stainless steel plate, a heat insulating material layer 12 having a gap on the inner surface of the outer packaging box 11, and a stainless steel plate on the inner surface of the heat insulating material layer 12. It consists of an interior box 13.
The air gap between the outer box 11 and the heat insulating material layer 12 becomes the air passage 14 referred to in the second embodiment, and the air passage 14 extends over the entire length in the width direction of the inner side surface of the outer box 11 and the hot pack P. 8 extends in the vertical direction from the upper and lower surfaces (in FIG. 8, the top and bottom surfaces in the chamber), the lower end opens to the bottom surface of the heating chamber 1, and the upper end reaches the control chamber C.

The lower end of the air passage 14 is an air intake hole (air intake port) 15, and the upper end is separated from the control chamber C by a partition plate 16 and becomes an air discharge hole (air discharge port) 17. Each has a louver. For this reason, air a ′ enters through the louver from the lower end opening 15 of the air passage 14, reaches the upper end as an upward flow due to heat, and is discharged from the upper end opening 17. Due to the circulation of the air a ′ in the ventilation path 14, the hot air reaching from the inside to the gap is taken away. For this reason, the exterior box 11 is not heated excessively. In the figure, reference numeral 18 denotes a reinforcing rib, and the rib 18 is also formed with a vent hole 19.
In addition, although the vent path can be formed in the door 2 as well, it is not formed in this embodiment. Further, the configuration of the heater 9, the inner plate 5 in the warehouse, the cages 6a, 6b, etc. is the same as that of the first embodiment.

  This Embodiment 2 is the above structure, and similarly, the temperature ° C. measured at each measurement point (1-1) to (2-8) in FIG. 10 when a paraffinic heat insulating agent is used for the hot pack P. It is shown in Table 2 below.

  From this Table 2, also in this Embodiment 2, each hot pack P is similarly heated to about 60 ° C. or higher in about 4 to 5 hours, and the entire inside of the heating chamber 1 is almost uniform. It can be understood that all the hot packs P that have been warmed are warmed almost uniformly and that the warming can be performed smoothly. On the other hand, it can be understood that the side surfaces (1-6 points, 2-7 points) of the outer box 11 are suppressed to 47 ° C. or less and do not reach a temperature at which they feel uncomfortable even if they are touched.

In Embodiments 1 and 2 above, the heater 9 is provided on the backside of the cabinet, the inner surface of the door 2, each shelf other than the middle plate, etc., in addition to the side wall, the bottom wall, and the middle plate 5. Can also be selectively provided. When the heater 9 is provided on each shelf, a plate material similar to the middle plate 5 is installed on the shelf portion, and the heater is provided on the plate material.
Each heater 9 can be divided, and the divided heaters 9 can be energized and finely controlled (in detail). At this time, the outputs of the heaters 9a, 9b, 9c of the side wall, the bottom wall, and the partition member are the total value of the divided heaters.
Furthermore, the rail 7 of the car 6b thereon can also be used by the intermediate plate 5, and the other car 6a can also use the rail 7 by the same plate material as the intermediate plate 5. This heating cabinet 1 can be equipped with a storage battery so that it can be heated even during a power failure.

The idea of forming the air passage 14 between the outer box 11 and the heat insulating material layer 12 is the heating in which the partition member 5 is provided or a plurality of heaters 9a, 9b, 9c are provided as in the first and second embodiments. Not only the storage 1 but other modes of heating, such as a conventional hot pack storage warmer with heaters only on both side walls, and a warm storage for storing food, etc. It can be employed in a temperature device.
As described above, since the embodiment of the present invention can be considered other than the above-described heating device, the scope of the present invention is indicated by the scope of claims, and within the meaning and scope equivalent to the scope of claims. Of course, all modifications of are intended to be included.
