[0003] FIG. 4 is a schematic diagram of an electrical stimulation wearing device 100 disclosed in Patent Document 1. Referring to FIG. 4, Patent Document 1 discloses an electrical stimulation wearing device 100 including a band 110 that is stretchable in the longitudinal direction, a conductive electrode accommodating portion 130 that accommodates an electrode 120, and a first hook-and-loop fastener 140 on the front surface of the band 110, and a contact 150 to which a conductive wire for applying electricity to the electrode 120 is connected, and a second hook-and-loop fastener 160 on the back surface of the band 110.

[0004] [Patent Document 1] Utility Model Registration No. 3194492 Summary of the Invention [Problem to be solved by the invention]

[0005] If an electrical stimulation garment such as that disclosed in Patent Document 1 is left in an everyday environment, its surface temperature will drop below that of the human body, and the user may feel cold when wearing it. In particular, because electrodes generally tend to lose temperature easily, the cold sensation is easily transmitted via the electrode housing, and users who dislike the cold sensation may dislike wearing an electrical stimulation garment altogether. Another possible use method is to soak the electrode housing with a liquid such as water to improve the conductivity of the electrode housing and enhance the effect of electrical stimulation. In this case, the temperature of the electrode housing will be further reduced, making the user feel even colder when wearing the device.

[0006] To mitigate the cold sensation felt when wearing the electrical stimulation wearing device as described above, it is preferable to place the electrical stimulation wearing device in a heating chamber and warm it before wearing it. Here, uneven heating of the electrical stimulation wearing device heated in the heating chamber may cause discomfort to the wearer. Therefore, when warming the electrical stimulation wearing device, it is necessary to heat the heating chamber evenly to prevent uneven heating of the electrical stimulation wearing device. Therefore, conventionally, heating units (heaters) have been provided on the top wall, two side walls, and bottom wall of the heating chamber to heat the heating chamber evenly.

[0007] However, in the conventional heating method described above, heating units must be used at four locations, which increases costs.

[0008] In view of these points, an object of the present invention is to provide a heating cabinet that uses only one heating section and is capable of suppressing uneven heating that occurs in the electrical stimulation wearing device inside the cabinet. [Means for solving the problem]

[0009] In order to solve the above problems, the warming cabinet according to the present invention is: (1) a warming cabinet for warming an electrical stimulation device, which includes a warming unit provided at one location inside the warming cabinet, a control unit for controlling the warming unit, and a plurality of temperature measuring units for measuring the temperature inside the warming cabinet. When the measured temperatures in all of the plurality of temperature measuring units are below a threshold value S1, warming is performed by the warming unit in a first mode in which a warming pattern of turning on for A1 seconds and turning off for A2 seconds per cycle is repeated (where A1 ≥ A2) in response to a signal output from the control unit. When the measured temperatures in all of the plurality of temperature measuring units are above a threshold value S2 (where S1 < S2), warming is performed by the warming unit in a second mode in which a warming pattern of turning on for B1 seconds and turning off for B2 seconds per cycle is repeated (where B1 < B2) in response to a signal output from the control unit.

[0010] (2) The threshold value S1 is 60°C or higher and 66°C or lower, the duty ratio in the first mode in the control unit is 0.5 or higher and 0.7 or lower, and A1 in the first mode is 0.5 seconds or higher and 1 second or lower. The warming cabinet according to (1).

[0011] (3) The threshold value S2 is 70°C or higher and 74°C or lower, the duty ratio in the second mode in the control unit is 0.1 or higher and 0.17 or lower, and B2 in the second mode is 5 seconds or higher and 10 seconds or lower. The warming cabinet according to (2).

[0012] (4) When the measured temperatures in all of the plurality of temperature measuring units are above a threshold value S3 (where S3 > S2), warming by the warming unit is stopped by the control unit. The threshold value S3 is 75°C or higher and 82°C or lower. The warming cabinet according to (3).

[0013] (5) The warming cabinet further includes a door state detection unit for detecting the opening and closing of the door of the warming cabinet. When it is detected by the door state detection unit that the door is open, warming by the warming unit is stopped by the control unit. The warming cabinet according to (1).

[0014] (6) A heating cabinet according to any one of (1) to (5), further comprising a placement section for placing the electrical stimulation wearing device, the heating section being provided below the placement section, and the placement section being provided with at least one opening for ventilating air below the placement section and air above the placement section.

[0015] (7) The heating cabinet described in (6), wherein the plurality of temperature measuring units are composed of a first temperature measuring unit and a second temperature measuring unit, the first temperature measuring unit is provided directly above the placement unit, and the second temperature measuring unit is provided directly below the ceiling wall of the heating cabinet. [Effects of the Invention]

[0016] According to the heating cabinet of the present invention, uneven heating occurring in the wearing device for electrical stimulation inside the cabinet can be suppressed by using only one heating section. [Brief explanation of the drawings]

[0017] [Figure 1] FIG. 2 is a front view of the heating chamber 1 in this embodiment. [Figure 2] 3 is a schematic diagram illustrating the heating pattern of the heating unit 6. FIG. [Figure 3] 4 is a flowchart showing a heating flow in the heating compartment 1 in this embodiment. [Figure 4] 1 is a schematic diagram of an electrical stimulation wearing device 100 disclosed in Patent Document 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0018] (Configuration of heating cabinet 1) The heating cabinet 1 of this embodiment will be described below with reference to FIG. 1. FIG. 1 is a front view of the heating cabinet 1 of this embodiment. Note that the door (which opens to the right) of the heating cabinet 1 is omitted in FIG. 1. Referring to FIG. 1, the heating cabinet 1 includes a rectangular bottom wall 2, a top wall 3 having a shape similar to the bottom wall 2, and three side walls 4 connected to each other. This gives the heating cabinet 1 a box-like shape with an opening 5. Closing this opening 5 with a door (not shown) blocks the exchange of heat between the inside of the heating cabinet 1 and the outside. To prevent heat from escaping from the inside of the heating cabinet 1 to the outside, for example, a thermal insulator may be disposed on the inner wall of the heating cabinet 1. The thermal insulator is not particularly limited, but chloroprene sponge, for example, can be used. The material of the heating cabinet 1 itself is not particularly limited, but preferably has a predetermined degree of rigidity, and electro-galvanized steel sheet (SECC), for example, can be used.

[0019] Next, the internal structure of the heating chamber 1 will be described. In this embodiment, the electrical stimulation wearing device 100 shown in FIG. 4 is heated. The heating chamber 1 includes a heating unit 6, a placing unit 7, and a control unit 8. The heating unit 6 is provided on the bottom wall 2 of the heating chamber 1 and supplies heat to heat the electrical stimulation wearing device 100. A known heating device or heating element can be used as the heating unit 6, and a Coats heater, for example, can be used. A Coats heater is a heating device that uses near-infrared radiation. A Coats heater is preferable in terms of power cost because it efficiently converts input power into infrared rays. Furthermore, compared to other heating devices, a Coats heater has a shorter time lag from the start of current application to heat generation, which shortens the timing at which heating of the electrical stimulation wearing device 100 begins, allowing the electrical stimulation wearing device 100 to be heated more quickly.

[0020] The support unit 7 is provided above the heating unit 6 to prevent the electrical stimulation wearing device 100 from coming into direct contact with the heating unit 6. By placing the electrical stimulation wearing device 100 on this support unit 7, the electrical stimulation wearing device 100 is warmed by the heat from the heating unit 6 below. The structure of the support unit 7 is not particularly limited, but is preferably a structure that allows heat from the heating unit 6 to be easily transferred to the placed electrical stimulation wearing device 100. For example, a structure having at least one opening that allows air to circulate between the air below the support unit 7 and the air above the support unit 7 (such as a mesh member with linear members arranged in a mesh pattern or a flat plate with at least one hole penetrating in the thickness direction) is preferred. In particular, when the support unit 7 is a mesh member, by setting the mesh size to an appropriate size, liquid (such as sweat or water) adhering to the electrical stimulation wearing device 100 can be kept on the support unit 7 and prevented from dripping onto the heating unit 6.

[0021] Inside the heating chamber 1, a first temperature measuring unit 91 is provided near the mounting unit 7 (directly above the mounting unit 7 in this embodiment), and a second temperature measuring unit 92 is provided near the top wall 3 of the heating chamber 1 (directly below the top wall 3 in this embodiment). The first temperature measuring unit 91 and the second temperature measuring unit 92 may be, for example, thermistors, but are not limited to this and any known temperature measuring device or temperature measuring element may be used. The control unit 8 controls the heating pattern of the heating unit 6 in accordance with the measured temperature T1 of the first temperature measuring unit 91 and the measured temperature T2 of the second temperature measuring unit 92 (details will be described later).

[0022] Heating cabinet 1 may include door state detection unit 93 that detects whether a door (not shown) of opening 5 of heating cabinet 1 is open or closed. If door state detection unit 93 detects that the door (not shown) of heating cabinet 1 is open, controller 8 can be configured to stop heating by heating unit 6. This prevents heating in a situation where heat from heating cabinet 1 is likely to escape to the outside, allowing electrical stimulation wearing device 100 to be heated more efficiently.

[0023] As described above, in order to heat the inside of a heating cabinet evenly and prevent uneven heating of the electrostimulation wearing device 100, a heating cabinet with heating units 6 provided in four locations (two locations on the bottom wall 2, the top wall 3, and the side wall 4) has conventionally been used. However, the cost of such a heating cabinet is high due to the large number of heating units 6. The most effective way to reduce costs is to reduce the number of heating units 6 to just one.

[0024] However, when heating unit 6 is provided in only one location and a conventional heating pattern is implemented, the heat radiated from heating unit 6 overheats the portion of electrical stimulation wearing device 100 that is close to heating unit 6, resulting in uneven heating in electrical stimulation wearing device 100. Therefore, the present inventors conducted extensive research and came up with the idea that, even when heating unit 6 is provided in only one location, by controlling the heating pattern of heating unit 6 intermittently, it is possible to heat the inside of heating chamber 1 uniformly and prevent uneven heating in electrical stimulation wearing device 100.

[0025] A method for controlling the heating pattern of the heating unit 6 will be described below. Fig. 2 is a schematic diagram illustrating the heating pattern of the heating unit 6. The upper graph in Fig. 2 shows the changes over time in the measured temperature T1 of the first temperature measuring unit 91 and the measured temperature T2 of the second temperature measuring unit 92, with the measured temperature T1 of the first temperature measuring unit 91 shown by a solid line and the measured temperature T2 of the second temperature measuring unit 92 shown by a dashed dotted line. The lower graph in Fig. 2 shows the control signal sent from the control unit 8 to the heating unit 6.

[0026] 2, when the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are equal to or lower than threshold value S1, it is determined that the temperature inside heating chamber 1 is insufficient and that "electrical stimulation wearing device 100 is not sufficiently warmed," and heating unit 6 performs heating in the first mode to increase the temperature of electrical stimulation wearing device 100. In the first mode, controller 8 performs intermittent control by outputting a signal to repeat a pattern in which "ON for A1 seconds, OFF for A2 seconds (where A1≧A2)" is one cycle (i.e., duty ratio D1≧0.5). This intermittent control causes heating unit 6 to repeat a heating pattern in which "ON for A1 seconds, OFF for A2 seconds" is one cycle (first mode). By appropriately setting the ON time A1 and OFF time A2 within one cycle in the first mode (provided that A1≧A2), the rate of temperature rise within heating chamber 1 can be appropriately changed, for example, A1=1 (second) and A2=0.5 (seconds). Furthermore, threshold value S1 may be set to an appropriate value as a threshold for determining whether heating of electrical stimulation wearing device 100 is insufficient, and can be set to, for example, 60°C or higher and 66°C or lower, and preferably 64°C.

[0027] The duty ratio D1 in the first mode in the control unit 8 is preferably 0.5 or more and 0.7 or less. By setting D1 to 0.5 or more, a sufficient heating time can be ensured, and the electrical stimulation wearing device 100 can be sufficiently warmed. On the other hand, by setting D1 to 0.7 or less, local overheating of the electrical stimulation wearing device 100 can be further suppressed.

[0028] The ON time A1 within one cycle in the first mode is preferably 0.5 seconds or more and 1 second or less. By setting A1 to 0.5 seconds or more, sufficient heating time can be ensured, and the electrical stimulation wearing device 100 can be sufficiently heated. On the other hand, by setting A1 to 1 second or less, local overheating of the electrical stimulation wearing device 100 can be further suppressed. In particular, when a Coats heater is used as the heating unit 6, as described above, the time lag from the start of current application to heat generation is short, so by setting A1 to 1.0 second or less, local overheating of the electrical stimulation wearing device 100 can be effectively suppressed.

[0029] Referring to FIG. 2, when the measured temperature T1 of the first temperature measuring unit 91 and the measured temperature T2 of the second temperature measuring unit 92 are not less than the threshold value S2 (where S1 < S2), it is determined that the internal temperature of the heating chamber 1 is sufficiently high and "the electric stimulation device 100 is sufficiently warmed up", and the temperature of the electric stimulation device 100 is decreased by performing heating in the second mode in the heating unit 6. In the second mode, the control unit 8 performs signal output for intermittent control so as to repeat a pattern of "ON for B1 seconds and OFF for B2 seconds (where B1 < B2)" as one cycle (that is, the duty ratio D2 < 0.5). By this intermittent control, the heating unit 6 repeats a heating pattern of "ON for B1 seconds and OFF for B2 seconds" as one cycle (second mode). By appropriately setting the ON time B1 and the OFF time B2 within one cycle in the second mode, the temperature decrease rate in the heating chamber 1 can be appropriately changed (where B1 < B2), for example, it can be set to B1 = 1 (second) and B2 = 5 (seconds). Further, the threshold value S2 may be set to an appropriate value (where S1 < S2) as the threshold for whether the electric stimulation device 100 is sufficiently heated, for example, it can be set to not less than 70°C and not more than 74°C, and preferably 72°C.

[0030] The duty ratio D2 in the second mode in the control unit 8 is preferably not less than 0.1 and not more than 0.17. By setting D2 to not less than 0.1, it is possible to suppress the heating pause time from becoming excessively long, and thus it is possible to suppress a rapid temperature decrease of the electric stimulation device 100. On the other hand, by setting D2 to not more than 0.17, it is possible to sufficiently ensure the heating pause time and suppress a further temperature increase of the electric stimulation device 100.

[0031] The OFF time B2 within one cycle in the second mode is preferably not less than 5 seconds and not more than 10 seconds. By setting B2 to not less than 5 seconds, it is possible to sufficiently ensure the heating pause time and suppress a further temperature increase of the electric stimulation device 100. On the other hand, by setting B2 to not more than 10 seconds, it is possible to suppress the heating pause time from becoming excessively long, and thus it is possible to suppress a rapid temperature decrease of the electric stimulation device 100.

[0032] As described above, in the control unit 8 provided in the warming cabinet 1 according to the present invention, by switching between the first mode and the second mode of the warming unit 6, the temperature inside the warming cabinet 1 can be appropriately maintained in a temperature range generally of S1 or higher and S2 or lower. And, as described in the above first mode and second mode, the control unit 8 does not perform control to constantly warm the warming unit 6, but performs intermittent control so that the ON time (warming time) and the OFF time (warming pause time) occur alternately. The inventor of the present invention has found that by providing a warming pause time by this intermittent control, the air warmed during the warming time convects inside the warming cabinet during the warming pause time, so that while uniformly warming the inside of the warming cabinet, the heat unevenness generated in the electrical stimulation wearing device 100 can be suppressed.

[0033] In order to suppress overheating of the electrical stimulation wearing device 100 due to excessive temperature rise inside the warming cabinet 1, a threshold value S3 where S2 < S3 is provided, and when the measured temperature T1 of the first temperature measuring unit 91 and the measured temperature T2 of the second temperature measuring unit 92 become S3 or higher, the control unit 8 may be configured to control to stop the warming in the warming unit 6. The threshold value S3 may be set to an appropriate value as a threshold value for whether the electrical stimulation wearing device 100 is overheated. For example, it can be set to 75 (°C) ≤ S3 ≤ 82 (°C).

[0034] (Regarding the warming flow in the warming cabinet 1) Hereinafter, the flow of warming the electrical stimulation wearing device 100 in the warming cabinet 1 of the present embodiment will be described. FIG. 3 is a flowchart showing the warming flow in the warming cabinet 1 in the present embodiment.

[0035] Referring to FIG. 3, first, the door state detection unit 93 detects whether the door of the heating chamber 1 is closed (S10). If the door is not detected (S10 No), a notification is issued that the door is not closed (S20), and after a predetermined time has elapsed, the state of the door is detected again (S10). As a notification means, for example, a method of lighting an LED (not shown) provided on the exterior of the heating chamber 1 can be considered, but this is not limited thereto, and known notification means (e.g., sound, etc.) can also be used. If the door is detected to be closed (S10 Yes), the control unit 8 determines whether the measured temperature T1 of the first temperature measuring unit 91 and the measured temperature T2 of the second temperature measuring unit 92 are both equal to or lower than the threshold value S1 (S30).

[0036] If the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are both S1 or lower (S30 Yes), it is determined that "the temperature inside heating chamber 1 is insufficient and electrostimulation wearing device 100 is not sufficiently warmed," and heating unit 6 performs heating in the first mode in response to a signal output from control unit 8 (S40). After a predetermined time has elapsed, control unit 8 determines whether the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are both equal to or higher than threshold value S3 (S50). The control by control unit 8 for heating unit 6 in the first mode has been described above, so a description thereof will be omitted.

[0037] On the other hand, if at least one of the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 91 exceeds S1 (S30 No), it is determined that "the internal temperature of heating chamber 1 is high and electrical stimulation wearing device 100 is sufficiently warmed," and control unit 8 makes the determination of S50 without going through the heating step in the first mode (S40).

[0038] If the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are both equal to or higher than threshold value S3 (Yes in S50), it is determined that "electrical stimulation wearing device 100 has been overheated due to an excessive temperature rise inside heating chamber 1," and heating by heating unit 6 is stopped by controller 8. On the other hand, if at least one of the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 is less than threshold value S3 (No in S50), it is determined that "electrical stimulation wearing device 100 has not been overheated," and controller 8 determines whether the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are both equal to or higher than threshold value S2 (S60).

[0039] If the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are both equal to or higher than threshold value S2 (S60 Yes), it is determined that "the temperature inside heating chamber 1 is high and electrostimulation wearing device 100 is sufficiently warmed," and heating unit 6 performs heating in the second mode in response to a signal output from control unit 8 (S70), and after a predetermined time has elapsed, control unit 8 again determines whether the measured temperature T1 of first temperature measuring unit 91 and the measured temperature T2 of second temperature measuring unit 92 are both equal to or lower than S1 (S30). The control by control unit 8 for heating unit 6 in the second mode has been described above, so a description thereof will not be repeated.

[0040] On the other hand, if at least one of the measured temperature T1 of the first temperature measuring unit and the measured temperature T2 of the second temperature measuring unit is below threshold value S2 (No in S60), it is determined that "the temperature inside the heating chamber is not sufficient and the electrical stimulation wearing device is not sufficiently warmed," and the control unit 8 makes the determination in S30 without going through the heating step in the second mode (S70).

[0041] According to the configuration of the warming chamber 1 in this embodiment, the temperature inside the warming chamber 1 is substantially uniform. On the other hand, due to the physical distance relationship with the warming unit 6, the measured temperature T1 of the first temperature measuring unit 91 tends to be slightly higher than the measured temperature T2 of the second temperature measuring unit 92. Therefore, in this embodiment, two measured temperatures, the measured temperature T1 of the first temperature measuring unit 91 and the measured temperature T2 of the second temperature measuring unit 92, are used to determine the warming mode to be adopted. However, the installation positions of the temperature measuring units are not limited to the positions of the first temperature measuring unit 91 and the second temperature measuring unit 92 in this embodiment. However, in order to confirm the temperature distribution inside the warming chamber 1, the first temperature measuring unit 91 and the second temperature measuring unit 92 are preferably installed at different heights.

[0042] (Variant example) The number of temperature measuring units is not particularly limited as long as there are a plurality of them. In this case, according to the flowchart of FIG. 3, in S30, when the measured temperatures at a plurality of temperature measuring units are all below the threshold value S1, heating is performed by the heating unit 6 in the first mode in which a heating pattern with A1 seconds ON and A2 seconds OFF per cycle (where A1 ≥ A2) is repeated according to the signal output from the control unit 8. In S60, when the measured temperatures at a plurality of temperature measuring units are all above the threshold value S2, heating is performed by the heating unit 6 in the second mode in which a heating pattern with B1 seconds ON and B2 seconds OFF per cycle (where B1 < B2) is repeated according to the signal output from the control unit 8. In S50, when the measured temperatures at a plurality of temperature measuring units are all above the threshold value S3, the heating by the heating unit 6 is stopped by the control unit 8. Even in this case, in order to confirm the temperature distribution inside the warming chamber 1, each temperature measuring unit is preferably installed at a different height

[0043] (Variant example) In the above embodiment, the heating unit 6 is provided on the bottom wall 2, but the installation location of the heating unit 6 is not limited to the bottom wall 2 and may be provided on the top wall 3 or the side wall 4. However, since heat usually moves from bottom to top, in order to warm the electric stimulation device 100 more uniformly, it is preferable to provide the heating unit 6 below the placement unit 7 inside the warming chamber 1, and more preferably on the bottom wall 2.

[0044] (Variation) In the embodiment described above, electrical stimulation wearing device 100 is placed on placing section 7 and thereby placed inside heating chamber 1. However, the method of placing electrical stimulation wearing device 100 inside heating chamber 1 is not limited to this, and for example, electrical stimulation wearing device 100 may be placed inside heating chamber 1 by providing a hanging hook (not shown) on top wall 3 of heating chamber 1 and hanging electrical stimulation wearing device 100 on the hook.
