Description

[Technical field]

[0001] The present invention relates to an exercise machine having an exercise room unit and a tank for storing water or hot water. [Background technology]

[0002] Conventionally, unit baths that have a bathtub for bathing in a bathtub and a washing area for showering have been in practical use. For example, there is a unit bath that has a bathtub and a washing area in a room enclosed by walls, a door that allows access to the washing area is provided on the wall surrounding the washing area, and a mixing faucet for supplying hot and cold water is provided in the washing area (see, for example, Patent Document 1).

[0003] Also, an underwater walking device in which a treadmill is provided at the bottom of a bathtub has been put to practical use and is used for lower body rehabilitation, muscle training, and the like (see, for example, Patent Document 2).

[0004] However, when changing from bathtub bathing to shower bathing or underwater walking, one must move between the bathtub, the washing area, and the underwater walking device. In particular, when using the underwater walking device, one must climb to the top of the device using the attached stairs and then climb down the ladder into the water tank. This makes it inconvenient to move around, and it can be difficult for people who require care to use it.

[0005] Therefore, a bathing device that allows bathtub bathing, shower bathing, and underwater walking in one bathing space has been proposed (for example, see Patent Document 3). In the device described in Patent Document 3, a tank that supplies water to the room where underwater walking is performed is provided separately from the bathing device, so the space required for installation is large.

[0006] In recent years, the elderly population has increased, and the number of people who need nursing care is also increasing due to the increase in the number of people who are bedridden due to the difficulty of walking. For this reason, exercises to increase muscle strength at rehabilitation day care centers have been increasing in recent years as a preventative measure against the need for nursing care. Muscle training for the elderly can hurt their joints, and walking underwater in a pool requires travel to and from the pool facility. This is because walking underwater is not possible in a conventional bathtub.

[0007] In addition, a next-generation bathing device that allows exercise is also known, which consists of an exercise room unit (main bathtub) that can be used for underwater walking, full-body bathing using a chair, and showering, with heat-insulated tanks on either side, allowing the tanks to be used as bathtubs as well (see, for example, Patent Document 4). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Publication No. 8-260722 [Patent Document 2] Japanese Patent Application Publication No. 8-206251 [Patent Document 3] JP 2011-15849 A [Patent Document 4] Patent No. 6635572 Summary of the Invention [Problem to be solved by the invention]

[0009] By the way, hot and cold alternating baths have been attracting attention in recent years because they cause blood vessels to repeatedly contract and expand in a short period of time, training the autonomic nervous system and helping to recover from fatigue, as well as supporting the recovery from injuries, relieving muscle pain, and improving performance.

[0010] Therefore, the present invention was made by taking the bathing equipment for exercise described in the above-mentioned Patent Publication No. 6635572 one step further and developing an equipment that also allows for hot and cold alternating bathing. The object of the present invention is to provide an exercise equipment that allows for hot and cold alternating bathing. [Means for solving the problem]

[0011] The present invention is an exercise machine capable of performing exercises including water walking, and comprises an exercise room unit having a unit housing with an open top, a tank for storing water or hot water which is supplied to the unit housing and returned from the unit housing, a piping line connecting the tank and the exercise room unit, an electromagnetic valve means and a pump means provided in the middle of the piping line, and a control means for controlling the electromagnetic valve means and the pump means. The tank includes a first tank and a second tank in which water of different temperatures is stored, the first tank stores water that is hotter than the water in the second tank, and the control means has a mode selection means for selecting one mode from a plurality of modes including a hot and cold alternating bath mode and an underwater walking mode.

[0012] This allows water of different temperatures to be stored in the first and second tanks, and by selectively supplying and returning this water to the exercise room unit through piping, it is possible to realize modes such as alternating hot and cold baths and underwater walking.

[0013] In addition, this exercise equipment is characterized in that when the hot and cold alternating bath mode is selected by the mode selection means of the control means, the control means controls the solenoid valve means and the pump means to alternately repeat the supply and return of water at a predetermined temperature between the first tank and the exercise chamber unit, and the supply and return of water at a predetermined temperature between the second tank and the exercise chamber unit.

[0014] This allows for alternating supply and return of water between the first tank and the exercise room unit, and between the second tank and the exercise room unit, to easily achieve alternating hot and cold baths that alternate between water of different temperatures a set number of times.

[0015] In addition, this exercise equipment is characterized in that when the underwater walking mode is selected by the mode selection means of the control means, the control means controls the solenoid valve means and the pump means to supply water of a predetermined temperature from the first tank and the second tank, respectively, to the exercise room unit.

[0016] By supplying water of different temperatures from the first tank and the second tank to the exercise room unit, underwater walking exercise can be performed in water that is neither too hot nor too cold. Also, by supplying water from both tanks, it is possible to exercise with the right amount of water for underwater walking exercise.

[0017] This exercise equipment is also characterized in that the water level in the exercise chamber unit when the underwater walking mode is selected is higher than the water level in the exercise chamber unit when the hot and cold alternating bath mode is selected, and the temperature of the water filled in the exercise chamber unit when the underwater walking mode is selected is between the water temperature of the first tank and the water temperature of the second tank when the hot and cold alternating bath mode is selected.

[0018] This makes it possible to easily switch between hot and cold alternating baths and underwater walking by using two tanks with different water temperatures.

[0019] This exercise equipment is also characterized in that the water temperature stored in the first tank is 36 to 42°C, the water temperature stored in the second tank is 16 to 26°C, and the water temperature filled in the exercise chamber unit when the underwater walking mode is selected is 26°C to 34°C.

[0020] This allows the use of a tank on each side to provide water at a temperature suitable for alternating hot and cold baths, while by using tanks on both sides, the water temperature can be provided at a temperature suitable for underwater walking.

[0021] In addition, this exercise equipment has upper and lower water level detection sensors on the top and bottom of the first and second tanks, respectively, which detect upper and lower water levels, and the control means stops the water supply when the upper water level detection sensor detects that the water level has exceeded the upper limit, and stops the return of the water supply when the lower water level detection sensor detects that the water level has fallen below the lower limit.

[0022] This allows the control means and sensors to ensure operation at the correct water level.

[0023] In addition, in this exercise machine, the first tank includes a heater controlled by the control means.

[0024] This allows the water temperature in the first tank to be maintained. The heater is used to raise the temperature when water begins to be stored in the first tank, to raise the temperature when water that has cooled down due to being combined with water from the second tank in the underwater walking mode is returned, and to raise the temperature when water is stored in the first tank.

[0025] In addition, in this exercise equipment, a temperature detection sensor is provided in the first tank between the upper and lower water level detection sensors, and the control means receives a signal from the temperature detection sensor and stops heating by the heater when the set temperature is exceeded.

[0026] This avoids unnecessary heating by the heater and ensures that the water temperature is maintained.

[0027] In addition, the exercise room unit of this exercise machine is provided with a number of water level detection sensors that detect the water level in the unit housing, thereby ensuring that the water level is kept as required for hot and cold alternating baths and underwater walking. Effect of the Invention

[0028] The present invention is provided with a first tank and a second tank, and by storing water of different temperatures in these tanks, it is possible to easily switch between hot and cold alternating bath mode, underwater walking mode, etc. [Brief description of the drawings]

FIG. [Diagram 3] FIG. [Figure 4] FIG. [Diagram 5] (a) is a 3D drawing of the exercise device as seen from above and in front, and (b) is a 3D drawing of the exercise device as seen from above and in back. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] The following describes an embodiment of the present invention, but the invention is not limited to the following embodiment. Fig. 1 is a perspective view of an exercise device according to an embodiment of the present invention seen from above, Fig. 2 is a schematic cross-sectional view of the front part of the exercise device, and Fig. 3 is an explanatory diagram of how to use the exercise device.

[0031] <1. Exercise equipment configuration> As shown in Figures 1 and 2, exercise equipment 1 includes an exercise room unit 2, and a first tank 3 and a second tank 4 arranged on the left and right sides of exercise room unit 2. The rear part of exercise room unit 2 is a main bathtub that also serves as an exercise room for performing exercises such as water walking, and the front part (space portion S) houses piping between first tank 3 and second tank 4, electrical wiring, pump 5, motor 6 (for driving treadmill 7), etc. The first tank 3 and second tank 4 can each store approximately 600 liters of water.

[0032] The main bathtub, which is the rear part of the exercise room unit 2, is made into a unit housing 8 with an open top, inside which the user can do exercises such as water walking. A treadmill 7 is placed on the bottom of the inside, and a drive belt 9 driven by a motor 6 is placed on the bottom of the unit housing 8 so that the rotation direction of the drive belt 9 is almost the same as the front-to-rear direction of the unit housing 8. Operations such as running, stopping, and speed adjustment can be performed using a control panel 10 described later.

[0033] The left and right side surfaces of the unit housing 8 (exercise room unit 2) are first flat surfaces, while the first side tank 3 and the second side tank 4 have second flat surfaces facing the first flat surfaces on the side of the exercise room unit 2. The first side tank 3 and the second side tank 4 are arranged in contact with each other on both sides of the exercise room unit 2 with the first flat surface and the second flat surface in contact, so that the first side tank 3 and the second side tank 4 are close to each other on the left and right sides of the exercise room unit 2.

[0034] Therefore, they can be installed as one unit, and the exercise room unit 2, the two first side tanks 3, and the second side tank 4 can be arranged in a small installation space (occupied space).

[0035] Furthermore, by positioning and installing the first side tank 3 and the second side tank 4 in the motion chamber unit 2, the piping connection between the motion chamber unit 2 and the first side tank 3 and the second side tank 4 can be facilitated by connecting the ends of the pipes together with a single touch.

[0036] In addition, the first side tank 3 and the second side tank 4 have substantially the same overall external shape, and can be removed from the motion room unit 2 and installed in a location other than the side of the motion room unit 2. In this way, free space can be provided around the motion room unit 2, making it possible to make effective use of the space.

[0037] The unit housing 8 is made of FRP and has a box-like shape that is open at the top, with its height and front-to-rear length longer than its width, giving it a box-like appearance. As shown in Figure 3, the height of the unit housing 8 is such that most of the user's body can fit inside when the user is standing upright, and its width is large enough to allow the user to feel comfortable without feeling cramped, while still allowing for space saving.

[0038] In Fig. 3, L1 is the water level when a user is walking upright, and L2 is the water level when a user is sitting and bathing. The unit housing 8 is watertight and has sufficient strength to withstand the water pressure even when it is full of water. Access to the inside is through a watertight main door 8a provided on the rear wall. The main door 8a is opened and closed by a lever handle.

[0039] A control panel section 10 consisting of a waterproof tablet PC is provided on the front side of the side of the unit housing 8 via a support member 11 so as to be positioned above the opening of the unit housing 8 and be visible to the user.

[0040] The control panel 10 displays a filter use switch, a tank drain switch, a shower use drain switch, a spindle / Jacuzzi use switch, a tank water supply switch, a tank water return switch, etc., and each operation can be performed by selecting one of them. For example, when the filter use switch is selected and the filter is used, the drainage water from the first tank 3 and the second tank 4 is returned to the first tank 3 and the second tank 4 through the piping, the filter and the UV device arranged in the space S, etc.

[0041] The first side tank 3 stores hot water, and the second side tank 4 stores cold water, and the first side tank 3 and the second side tank 4 are connected to the exercise room unit 2 via piping (pipes that serve as a water supply pipe, a hot water supply pipe, and a drain pipe).

[0042] Then, solenoid valves MV1-MV9, SV1, SV2 (solenoid valve means) and pump 5 (water supply and drainage pump means) installed along this piping repeatedly supply and return hot water between the main bathtub (exercise room unit 2) and the first side tank 3, and supply and return cold water between the main bathtub (exercise room unit 2) and the second side tank 4, so that hot water or cold water stored in the first side tank 3 and the second side tank 4 is supplied or returned from the first side tank 3 and the second side tank 4 to the main bathtub (exercise room unit 2) in the unit housing 8.

[0043] That is, the first side tank 3, the second side tank 4 and the motion chamber unit 2 are connected through piping, and a plurality of solenoid valves MV1-MV9, SV1, SV2 (solenoid valve means) and a pump 5 (water supply / drainage pump means) provided along the way of the piping supply water from the first side tank 3 and the second side tank 4 to the motion chamber unit 2 and drain water back from the motion chamber unit 2 to the first side tank 3 and the second side tank 4. This water supply and return drainage are performed by controlling the solenoid valves MV1-MV9, SV1, SV2 and the pump 5 by a control means (not shown) according to a mode described below.

[0044] According to this type of exercise equipment 1, a purification unit with water supply and drainage functions including a filtration function is provided in the front part (space part S) of the exercise room unit 2, and the first side tank 3 and second side tank 4 arranged on the sides are connected to the purification unit by piping, which eliminates the need for piping or wiring work at the installation site, unlike conventional equipment in which the tank and filter are separate.

[0045] In the past, when taking a bath and walking in water or taking a shower, it was necessary to move, but now it is possible to replace the entire conventional bathroom (including the shower) with this main bathtub (exercise room unit 2), and at the same time, it becomes possible to walk in water to maintain and improve health.

[0046] Therefore, as a bathing device that allows walking in water, it is possible to maintain and promote health and prevent diseases. The exercise machine 1 configured in this way can be installed in rehabilitation rooms in hospitals, poolside or fitness rooms in sports clubs, or tiled floors in Western-style rooms or living rooms in ordinary homes.

[0047] Moreover, the piping of such a water supply system has a portion connected to the front upper portion of the first side tank 3 and the second side tank 4, and a portion connected to the front portion of the unit housing 8. That is, as shown in Fig. 4, for the first side tank 3, hot water from the hot water supply pipe 21 and cold water from the cold water supply pipe 22 are mixed at the first mixing tap 23 and the temperature is adjusted, and hot water is supplied to the unit housing 8 and the first side tank 3 by opening the electromagnetic opening / closing valve SV1.

[0048] Water is supplied from the water supply pipe 22 to the second tank 4 by opening the electromagnetic on-off valve SV2. The temperature is similarly adjusted, and a body shower can be performed by a shower means (not shown) or a shower can be performed with a shower head.

[0049] The hot water and cold water stored in the first tank 3 and the second tank 4 are drained through the drain ports 24a and 24a to the drain port 25 by opening the electromagnetic opening / closing valves MV6 and MV6, respectively. In addition, overflow from the first tank 3 and the second tank 4 is drained from the overflow port 24c through an overflow hose to the drain port 25.

[0050] Water is supplied from the first side tank 3 to the unit housing 8 through the pump 5 by opening the electromagnetic on-off valves MV3 and MV1, and then through the water supply / drain port 26. Water is drained (returned) from the unit housing 8 to the first side tank 3 by switching the electromagnetic three-way valve MV1 and returning the water to the first side tank 3 through the pump 5 and electromagnetic on-off valve MV5.

[0051] On the other hand, water is supplied from the second side tank 4 to the unit housing 8 through the water supply / drain port 26 by opening the electromagnetic on-off valve MV2 and switching the electromagnetic three-way valve MV1 to pass through the pump 5, and water is drained (returned) by switching the electromagnetic three-way valve MV1 to return the water to the second side tank 4 through the pump 5 and electromagnetic on-off valve MV4.

[0052] By repeating the water supply and return between the first tank 3 and the unit housing 8, and the water supply and return between the second tank 4 and the unit housing 8, the main bathtub is alternately filled with hot water (36-42°C) and cold water (16-26°C), making it easy to enjoy alternating hot and cold baths.

[0053] A gripping rod 20 (see FIG. 2) for the user is provided in the center in the front-rear direction inside the unit housing 8, and a spindle jet 27A and microbubbles 27B are also provided. A pillow 28A, a chair 28B and an LED 29 are provided near these, and a treadmill 7, which is an underwater conveyor for walking and running, is placed on the bottom. Reference numerals 34, 35 and 36 denote chambers.

[0054] As described above, the exercise room unit 2 is connected to the first tank 3 and the second tank 4 by piping, and water can be supplied to the exercise room unit 2 from the first tank 3 and the second tank 4. Therefore, water can be supplied to the exercise room unit 2 when used for underwater walking for rehabilitation, leg strengthening, etc.

[0055] For example, after a user enters the exercise room unit 2, when the user presses the hot water supply button for underwater walking displayed on the screen of the control panel section 10, the drain outlet 25 is automatically closed and preset amounts of hot water and cold water are automatically supplied from the first tank 3 and the second tank 4, respectively. Then, by mixing the hot water and cold water in the unit housing 8, the water temperature becomes 26°C to 34°C, which is appropriate for underwater walking, and the water supply from both tanks makes the water level higher than during a hot and cold alternating bath, reaching around the chest level when running (standing), which is appropriate for underwater walking (see L1 in Fig. 3).

[0056] Then, by setting the running speed of the treadmill 7 on the control panel unit 10 and pressing the run button, the belt starts to run, and the user can walk on the treadmill 7. It is also possible to take a shower.

[0057] When taking a bath after finishing walking in water, the temperature in the bathtub is maintained so as not to exceed the upper limit temperature by temperature control using a heater 30 (for example, 1 kW) in the first side tank 3. That is, the first side tank 3 is provided with a temperature detection sensor 33 that detects the temperature of the stored water, and the heater 30 controls the temperature based on a signal from the temperature detection sensor 33. And since warm water is stored in advance in the first side tank 3, a bath can be taken immediately.

[0058] <2. Operation of exercise equipment> Next, the operation of the driving device 1 will be described. First, when water filling into the first side tank 3 and the second side tank 4 is selected on the control panel section 10 (waterproof tablet PC) installed in the exercise room unit 2, water supply from the first side tank 3 and the second side tank 4 begins, respectively. When the water reaches a predetermined upper water level, this is detected by the tank water level sensors 31a, 31b, 32a, 32b and the water supply is automatically stopped.

[0059] In addition, instructions to start filling the bathtub or to make reservations can also be sent by mobile phone. The water stored in the first tank 3 and the second tank 4 is automatically purified by filtration and ultraviolet sterilization in the purification unit installed in the front part (space S) of the exercise room unit 2.

[0060] A user opens the main door 8a of the unit housing 8 (exercise room unit 2) and enters inside. If the main door 8a is not completely closed at that time, a lock confirmation sensor (not shown) will be activated and the user will not be able to enter the water.

[0061] Once it is completely locked, the mode can be selected on the control panel unit 10. That is, one of the hot and cold alternating bath, underwater walk, spa, and shower modes can be selected on the control panel unit 10. Each mode has a manual mode and an automatic mode.

[0062] For example, when the alternating hot bath mode is selected, if the auto mode is selected, the supply and return of hot water from the first tank 3 and cold water from the second tank 4 are automatically repeated alternately. Then, the microbubbles and jet bath are operated in sequence within a set time, and the LED 29 is automatically lit. When the operation is finished, the water is automatically drained.

[0063] When taking an alternating hot bath, you can also use the provided pillow 28A and chair 28B. On the other hand, in manual mode, you can select the water level and the time interval for alternating hot and cold water. This allows you to take an alternating hot bath according to the selected desired conditions. You can also select and use the microbubble or jet bath.

[0064] In the underwater walking mode, when the water level setting is selected in the manual mode and immersion in water is started, water starts to be supplied from both the first tank 3 and the second tank 4. After a certain time has elapsed (for example, 20 seconds) after immersion in water is started, it becomes possible to operate the speed button.

[0065] When the specified water level is reached, the jacuzzi and spindle jet can be operated. When the water is finished, the speed is stopped, drain is selected, the solenoid valve MV9 is opened, and the water is drained from the drain port 37. Bath water level sensors 38a, 38b, 38c, and 38d are provided to detect water levels of 0, 700, 900, and 1100 mm.

[0066] Meanwhile, in auto mode, the screen displays each course (level 1-5) from walking to running, and when you select a course, water supply starts automatically and the walking or running speed increases or decreases automatically. In this auto mode, the jacuzzi and spindle jets operate automatically, and the water drains automatically before ending. If you press the emergency stop button during auto mode, the auto mode will be interrupted and rapid draining will begin.

[0067] When spa mode is selected, the water level can be selected in manual mode, and the microbubbles or jet bath can be selected. On the other hand, when auto spa mode is selected, the water is filled automatically, the microbubbles and jet bath operate in sequence within a set time, the LED 29 also lights up automatically, and when finished, the water is automatically drained. When using the spa, the provided pillow 28A and chair 28B can be used. Also, when using spa mode, an aqua bike can be placed inside and used.

[0068] In the unlikely event that there is a power outage during underwater walking or spa mode and the water cannot be drained electrically, it can be drained by opening the manual drain valve installed inside.

[0069] When selecting the shower, either the body shower or the hand shower can be selected on the control panel 10. If the shower mode is selected on the control panel 10, the body shower will operate automatically, and if a shower head is to be used, a stopcock is used. When using the shower, the drain valve opens and the water is drained automatically. After the water has been drained, it is possible to go outside. To drain the water, select drain on the screen of the control panel 10, and the solenoid valve will open and the water will be drained.

[0070] <3. Other embodiments> As described above, the embodiment of the present invention has been described with reference to the drawings, but various additions and modifications can be made without departing from the spirit and scope of the present invention.

[0071] (i) A face recognition camera may be placed corresponding to the face position of a user in a standing state, and face recognition may be performed first in each mode. In that case, since the face recognition system is operating during operation, if the user falls over, the face recognition system will detect this, bring the water to an emergency stop, start rapid drainage, and activate an external alarm device.

[0072] (ii) A control panel section 10 consisting of a waterproof tablet PC is provided on the front side of the side of the unit housing 8, and a TV also consisting of a waterproof tablet PC can be provided alongside it. [Explanation of symbols]
