[Technical Field]

[0001] The present disclosure relates to a hot water supply system, a calorie consumption calculation method, and a program. [Background technology]

[0002] In recent years, hot water supply systems that allow not only normal bathing but also other types of bathing that are different from normal bathing have become known.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-170618 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, bathers have a desire to know how many calories they are consuming while bathing.

[0005] Therefore, an object of the present disclosure is to provide a hot water supply system etc. that allows a bather to understand the calorie consumption while bathing. [Means for solving the problem]

[0006] A hot water supply system according to one embodiment of the present disclosure is a hot water supply system that can be switched between a normal bathing state and a different bathing state that is a different type of bathing state from the normal bathing state, and is equipped with a remote control unit for switching between the normal bathing state and the different bathing state, a calculation unit for calculating the calories burned by the bather, and a display unit.When the normal bathing state is activated by the remote control unit, the calculation unit measures a first bathing period of the previously recorded bather in the normal bathing state and calculates the calories burned by the bather based on the first bathing period and a first calculation formula for calculating the calories burned by the previously recorded bather in the normal bathing state.When the different bathing state is activated by the remote control unit, the calculation unit measures a second bathing period of the previously recorded bather in the different bathing state and calculates the calories burned by the bather based on the second bathing period and a second calculation formula for calculating the calories burned by the previously recorded bather in the different bathing state.The display unit displays the calories burned calculated by the calculation unit.

[0007] Another aspect of the present disclosure is a calorie consumption calculation method, which displays the calories consumed by a bather, and which acquires at least one of a first bathing period of the previously recorded bather in a normal bathing state executed by a hot water supply system and a second bathing period of the previously recorded bather in a different bathing state that is a different type of bathing state from the normal bathing state.When the first bathing period is acquired, the calories consumed by the bather are calculated based on a first calculation formula for calculating the calories consumed by the previously recorded bather in the normal bathing state and the first bathing period.When the second bathing period is acquired, the calories consumed by the bather are calculated based on a second calculation formula for calculating the calories consumed by the previously recorded bather in the different bathing state and the second bathing period, and the calculated calories consumed by the bather are displayed on a display unit.

[0008] A program according to another aspect of the present disclosure is a program for causing a computer to execute the calorie expenditure calculation method. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Below, embodiments of the hot water supply system according to the present disclosure will be described in detail with reference to the drawings. Note that each of the embodiments described below represents a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, component arrangement and connection forms, steps and their order, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not recited in independent claims will be described as optional components.

[0012] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0013] Furthermore, each drawing is a schematic diagram and is not necessarily an exact illustration. In addition, in each drawing, substantially the same components are assigned the same reference numerals, and duplicated explanations may be omitted or simplified.

[0014] [Embodiment 1] (Hot water system) Fig. 1 is a block diagram showing the configuration of a hot water supply system 100 according to embodiment 1. As shown in Fig. 1, hot water supply system 100 includes a hot water supply device 200, a fine bubble generator 300, a room entry sensor 400, a hot water entry sensor 500, a remote control unit 600, and a display terminal 700.

[0015] Water heater 200 is a device for supplying hot water to a bathroom. Specifically, water heater 200 heats water to a temperature set by remote control unit 600 and supplies the water to the bathtub, faucet, shower, etc. in the bathroom. Water heater 200 can be of a gas water heater type, electric water heater type, heat pump type, oil water heater type, or the like.

[0016] The micro-bubble generator 300 is a device for generating micro-bubbles in the water accumulated in a bathtub. Specifically, the micro-bubble generator 300 includes a circulation path that circulates the water in the bathtub and returns it to the bathtub, a pump that extracts the water from the bathtub into the circulation path, and a gas-liquid mixer that temporarily stores the water passing through the circulation path and dissolves and mixes the micro-bubbles. The micro-bubble generator 300 mixes a large amount of micro-bubbles into the water in the bathtub. In this embodiment, a state in which the micro-bubble generator 300 is not activated and micro-bubbles are not mixed into the water in the bathtub is referred to as a normal bathing state, and a state in which the micro-bubble generator 300 is activated and micro-bubbles are mixed into the water in the bathtub is referred to as a heterogeneous bathing state. The heterogeneous bathing state is a state different in type from the normal bathing state.

[0017] The entrance sensor 400 is a sensor for detecting whether or not a user has entered the bathroom, and is, for example, a human presence sensor.

[0018] The bathing sensor 500 is a sensor for detecting whether or not the user is immersed in the bathtub, and is, for example, a water level sensor.

[0019] Remote control unit 600 accepts user operations and controls water heater 200 and fine bubble generator 300. Remote control unit 600 is installed, for example, inside or outside the bathroom. Remote control unit 600 includes touch panel 610 for operation, communication unit 620, microcomputer 630, physical switches, a speaker, etc.

[0020] The touch panel 610 is a display monitor that accepts various operations and displays various information. In other words, the remote control unit 600 has a display function. The set temperature of the hot and cold water in the bathtub and instructions to activate and deactivate the fine-bubble generator 300 are input to the remote control unit 600 by the user operating the touch panel 610 and physical switches.

[0021] The communication unit 620 is a communication module for communicating with the display terminal 700. The communication unit 620 may be a wireless communication module such as Wi-Fi or BLUETOOTH (registered trademark), or may be a wired communication module.

[0022] Microcomputer 630 controls water heater 200 and micro-bubble generator 300 based on various input instructions. For example, microcomputer 630 controls water heater 200 so that the water temperature in the bathtub reaches a set temperature. Furthermore, when microcomputer 630 receives an instruction to drive micro-bubble generator 300, it drives micro-bubble generator 300 to mix micro-bubbles into the hot and cold water in the bathtub. This creates a heterogeneous bathing state.

[0023] On the other hand, when the microcomputer 630 receives a command to stop the micro-bubble generator 300, it stops the micro-bubble generator 300. This returns the bath to the normal bathing state. The touch panel 610 may display at least one of the current water temperature, the set temperature, and the bathing state.

[0024] When the bath water sensor 500 detects a sudden rise in the water level in the bathtub, the microcomputer 630 determines that the user has immersed in the bathtub. Furthermore, when the bath water sensor 500 detects a sudden drop in the water level in the bathtub, the microcomputer 630 determines that the user has left the bathtub.

[0025] When the microcomputer 630 determines that the user (bather) has immersed in the bathtub based on the detection result of the bathing sensor 500, it starts measuring the bathing period based on the bathing state at that time (normal bathing state or different bathing state). After that, when the microcomputer 630 determines that the user has left the bathtub based on the detection result of the bathing sensor 500, it stops measuring the bathing period.

[0026] For example, if the microcomputer 630 determines that the bather is in a normal bathing state, it measures a first bathing period of the bather in the normal bathing state. On the other hand, if the microcomputer 630 determines that the bather is in a different bathing state, it measures a second bathing period of the bather in the different bathing state. In this way, the microcomputer 630 is an example of a first part that measures the first bathing period and the second bathing period.

[0027] The microcomputer 630 resets the first bathing period and the second bathing period when it detects a bather entering the bathroom based on the detection result of the entry sensor 400. After the reset, the microcomputer 630 determines the first bathing period and the second bathing period when it detects a bather leaving the bathroom based on the detection result of the entry sensor 400 after measuring at least one of the first bathing period and the second bathing period. The microcomputer 630 controls the communication unit 620 to transmit the determined first bathing period and the second bathing period to the display terminal 700.

[0028] The display terminal 700 is a terminal device that can communicate with the remote control unit 600. Examples of the display terminal 700 include a smartphone, a tablet terminal, a PC, a wearable device, and a tablet terminal. For example, the display terminal 700 can execute the functions of the second unit and the display unit according to the present disclosure by installing a predetermined application on a smartphone used by the bather.

[0029] The display terminal 700 includes a touch panel 710, a communication unit 720, and a microcomputer 730. The touch panel 710 accepts various operations and displays various information. The communication unit 720 is a communication module for communicating with the remote control unit 600. The communication unit 620 is a wireless communication module such as Wi-Fi or BLUETOOTH (registered trademark). The microcomputer 730 controls the touch panel 710 and the communication unit 720. The microcomputer 730 calculates the calories burned by the bather based on the first bathing period and second bathing period input via the communication unit 720.

[0030] Specifically, the microcomputer 730 stores a first calculation formula for calculating the calories burned by a bather in a normal bathing state and a second calculation formula for calculating the calories burned by a bather in a different bathing state.

[0031] FIG. 2 is a graph illustrating the first and second calculation formulas according to embodiment 1. FIG. 2 shows graph g1 of calories burned over time while at rest, graph g2 of calories burned over time while walking, graph g3 of calories burned over time while bathing in a normal bathing state, and graph g4 of calories burned over time while bathing in a different bathing state. These graphs g1 to g4 were obtained through experiments, simulations, etc. Graphs g3 and g4 also show that bathers burn more calories when bathing in a different bathing state than when bathing in a normal bathing state. In particular, the difference in calories burned becomes greater as time passes.

[0032] The first calculation formula is created based on graph g3. Specifically, the first calculation formula is a linear function that approximates graph g3. In the normal bathing state, microcomputer 730 calculates the calorie expenditure of the bather based on the first calculation formula and the first bathing period.

[0033] The second calculation formula is created based on graph g4. Specifically, graph g4 shows a convex curve from the start of bathing to a predetermined time point P, and a linear curve after the predetermined time point P. Therefore, the second calculation formula includes a third calculation formula that uses a nonlinear function up to the predetermined time point P and a fourth calculation formula that uses a linear function after the predetermined time point P. That is, in the heterogeneous bathing state, microcomputer 730 calculates the calorie expenditure up to the predetermined time point P using the third calculation formula and calculates the calorie expenditure after the predetermined time point P using the fourth calculation formula. The predetermined time point P is several minutes (e.g., 2 to 5 minutes). Thus, microcomputer 730 is an example of a second unit that calculates the calorie expenditure of the bather. That is, display terminal 700 is provided with a second unit (microcomputer 730), and remote control unit 600 is provided with a first unit (microcomputer 630). Therefore, hot water supply system 100 as a whole can be said to have a calculation unit that includes a first unit and a second unit.

[0034] After calculating the bather's calorie expenditure, the microcomputer 730 controls the touch panel 710 to display the bather's calorie expenditure on the touch panel 710. In other words, the touch panel 710 is an example of a display unit according to the present disclosure. The microcomputer 730 may record the bather's calorie expenditure as a history. In this case, for example, the calorie expenditure may be totaled for a predetermined period (one week, one month, six months, one year) and the total value may be displayed. At this time, the total calorie expenditure during the predetermined period may be converted into an amount of activity other than bathing and displayed. One example is, "If the total calorie expenditure during the predetermined period is converted into walking distance, the walking distance is 50 km." In this way, the calories consumed by bathing are converted into an amount of activity other than bathing, making it easier for the bather to realize the benefits of bathing. Furthermore, the trend in the calories consumed may be displayed. In this case, the bather can grasp the trend in the calories consumed.

[0035] (Calculation method for calories burned) Next, a calorie consumption calculation method according to the present disclosure will be described. This calculation method is realized by the microcomputer 730 of the display terminal 700 executing a program.

[0036] 3 and 4 are flowcharts showing the flow of the calorie expenditure calculation method according to Embodiment 1. Fig. 3 shows the processing executed by remote control unit 600, and Fig. 4 shows the processing executed by display terminal 700.

[0037] 3, microcomputer 630 of remote control unit 600 determines whether a bather has entered the bathroom based on the detection result of entrance sensor 400 (step S1). If microcomputer 630 determines that a bather has not entered the bathroom, it maintains that state, but if it determines that a bather has entered the bathroom, it proceeds to step S2.

[0038] In step S2, the microcomputer 630 resets the first bathing period and the second bathing period, and then proceeds to step S3.

[0039] In step S3, microcomputer 630 determines whether the bather is immersed in the hot water in the bathtub based on the detection result of bathing sensor 500. If microcomputer 630 determines that the bather is not immersed in the hot water in the bathtub, it maintains that state, but if it determines that the bather is immersed in the hot water in the bathtub, it proceeds to step S4.

[0040] In step S4, the microcomputer 630 determines whether the current bathing state is a normal bathing state or a different bathing state based on the operating state of the micro-bubble generator 300. Specifically, if the micro-bubble generator 300 is stopped, the microcomputer 630 determines that the current bathing state is a normal bathing state and proceeds to step S5. On the other hand, if the micro-bubble generator 300 is operating, the microcomputer 630 determines that the current bathing state is a different bathing state and proceeds to step S8.

[0041] In step S5, the microcomputer 630 measures the first bathing period, and then proceeds to step S6.

[0042] In step S6, microcomputer 630 determines whether the bather has left the bathtub based on the detection result of bath sensor 500. If microcomputer 630 determines that the bather has not left the bathtub, it maintains that state, but if it determines that the bather has left the bathtub, it proceeds to step S7.

[0043] In step S7, the microcomputer 630 stops measuring the first bathing period and proceeds to step S11.

[0044] In step S8, the microcomputer 630 measures the second bathing period, and then the process proceeds to step S9.

[0045] In step S9, microcomputer 630 determines whether the bather has left the bathtub based on the detection result of bath sensor 500. If microcomputer 630 determines that the bather has not left the bathtub, it maintains that state, but if it determines that the bather has left the bathtub, it proceeds to step S10.

[0046] In step S10, the microcomputer 630 stops measuring the second bathing period, and proceeds to step S11.

[0047] In step S11, microcomputer 630 determines whether the bather has left the bathroom based on the detection result of entry sensor 400. If microcomputer 630 determines that the bather has not left the bathroom, it proceeds to step S3, and if it determines that the bather has left the bathroom, it proceeds to step S12.

[0048] In step S12, the microcomputer 630 determines the first bathing period and the second bathing period, and then proceeds to step S13. At this time, if only the normal bathing state is being performed, only the first bathing period is measured, and the second bathing period is zero. On the other hand, if only the different bathing state is being performed, only the second bathing period is measured, and the first bathing period is zero. Furthermore, if both the normal bathing state and the different bathing state are being performed, both the first bathing period and the second bathing period are measured.

[0049] In step S13, the microcomputer 630 controls the communication unit 620 to transmit the determined first and second bathing periods to the display terminal 700.

[0050] Next, we will explain the processing executed by the display terminal 700. As shown in Fig. 4, in step S21, the microcomputer 730 of the display terminal 700 acquires the first bathing period and the second bathing period received by the communication unit 720, and proceeds to step S22.

[0051] In step S22, the microcomputer 730 calculates a first calorie expenditure based on the first bathing period and the first calculation formula, and then the process proceeds to step S23.

[0052] In step S23, the microcomputer 730 calculates a second calorie expenditure based on the second bathing period and the second calculation formula, and then proceeds to step S24.

[0053] In step S24, the microcomputer 730 calculates the calorie expenditure of the bather by adding up the first calorie expenditure and the second calorie expenditure, and then proceeds to step S25.

[0054] In step S25, microcomputer 730 controls touch panel 710 to display the calories burned by the bather on touch panel 710. Fig. 5 is an explanatory diagram showing an example of a display of calories burned according to embodiment 1. As shown in Fig. 5, touch panel 710 of display terminal 700 displays a list of the bathing state (normal bathing state or different bathing state), bathing period (first bathing period or second bathing period), and calories burned.

[0055] (Effects, etc.) As described above, the display unit displays the calorie consumption calculated by the calculation unit, so the bather can visually check the displayed content and recognize the calorie consumption while bathing. Therefore, the bather can understand the calorie consumption while bathing.

[0056] In hot water supply system 100 according to this embodiment, when the normal bathing state is selected by remote control unit 600, the calculation unit (microcomputer 630 and microcomputer 730) measures a first bathing period of the bather in the normal bathing state and calculates the calorie expenditure of the bather based on the first bathing period and a first calculation formula for calculating the calorie expenditure of the bather in the normal bathing state. On the other hand, when the different bathing state is selected by remote control unit 600, the calculation unit measures a second bathing period of the bather in the different bathing state and calculates the calorie expenditure of the bather based on the second bathing period and a second calculation formula for calculating the calorie expenditure of the bather in the different bathing state. In this way, the calorie expenditure of the bather in the normal bathing state and the calorie expenditure of the bather in the different bathing state are calculated, making it possible to calculate the effect of bathing other than normal bathing (different bathing state).

[0057] Since the bather consumes more calories in the different bathing states than in the normal bathing state, it is possible to calculate the calories consumed in the different bathing states that are more effective for the bather.

[0058] Since the second calculation formula includes a third calculation formula that uses a nonlinear function up to a specified point in time and a fourth calculation formula that uses a linear function from the specified point in time onwards, it is possible to more accurately reflect fluctuations in calorie consumption over time in different bathing conditions.

[0059] Even when a micro-bubble generating device generates micro-bubbles in the water in the bathtub to create different bathing conditions, it is possible to calculate the calories burned by the bather in the different bathing conditions.

[0060] The calculation unit is provided in the remote control unit 600 and includes a first unit (microcomputer 630) that measures the first and second bathing periods, and a second unit (microcomputer 730) that is provided in the display terminal 700 and calculates the calories burned by the bather. As a result, the measurement of the first and second bathing periods, which can be performed with light processing power, can be performed by the microcomputer 630 of the remote control unit 600, which has limited processing power. On the other hand, the calculation of calories burned, which requires processing resources, can be performed by the display terminal 700, which has ample processing power.

[0061] Furthermore, since the second section is provided in the display terminal 700, the calorie consumption calculated by the second section can be displayed on the display terminal 700. As described above, the first bathing period and the second bathing period are confirmed when the remote control section 600 detects that the bather has left the bathroom. For example, if the calorie consumption is displayed on the remote control section 600, the bather must re-enter the bathroom to view the remote control section 600 inside the bathroom, which is inconvenient. On the other hand, if the calorie consumption is displayed on the display terminal 700, the bather can easily grasp the calorie consumption by viewing their own display terminal 700 without having to re-enter the bathroom.

[0062] [Embodiment 2] In the second embodiment, the first and second calculation formulas are changed depending on various conditions, including individual conditions according to the characteristics of the bather and hot and cold conditions according to the characteristics of the hot and cold water in the bathtub.

[0063] The individual conditions include the bather's gender, age, etc. Male bathers tend to burn more calories while bathing than female bathers. Based on this, a first calculation formula and a second calculation formula for males and a first calculation formula and a second calculation formula for females are pre-determined. Regarding the age of the bather, the older the bather, the lower the calorie expenditure while bathing. Based on this, a first calculation formula and a second calculation formula for each age are pre-determined. The individual conditions are pre-entered into the display terminal 700. FIG. 6 is an explanatory diagram showing an example of an input screen G10 of the display terminal 700 according to the second embodiment. As shown in FIG. 6, the touch panel 710 of the display terminal 700 displays the input screen G10 for inputting the bather's characteristics. The input screen G10 has input fields for the bather's characteristics, such as age and gender. The display terminal 700 records each piece of bather information as it is entered into each input field. Once the display terminal 700 has recorded each piece of information, it is possible to omit the input work from the next time onward.

[0064] The hot and cold water conditions include the temperature of the hot and cold water in the bathtub, the amount of hot water, etc. Regarding the hot and cold water temperature, the higher the temperature of the hot and cold water, the more calories burned while bathing. Based on this, a first calculation formula and a second calculation formula are determined in advance for each hot and cold water temperature. Regarding the amount of hot water, the greater the amount of hot water, the more calories burned while bathing. Based on this, a first calculation formula and a second calculation formula are determined in advance for each amount of hot water. The hot and cold water conditions are obtained from various sensors (water temperature sensor, water level sensor) when the microcomputer 630 of the remote control unit 600 measures the first bathing period and the second bathing period. The microcomputer 630 transmits the hot and cold water conditions, along with the first bathing period and the second bathing period, to the display terminal 700.

[0065] The microcomputer 730 of the display terminal 700 stores a first calculation formula and a second calculation formula corresponding to each individual condition and hot and cold water condition. Fig. 7 is an explanatory diagram showing tables T10 and T20 that schematically show the first calculation formula and the second calculation formula corresponding to each individual condition and hot and cold water condition according to the second embodiment. Fig. 7(a) shows table T10 for men, and Fig. 7(b) shows table T20 for women. Fig. 7 shows tables T10 and T20 corresponding to gender, age, and hot water temperature, but they may also be tables that include hot water volume.

[0066] The microcomputer 730 of the display terminal 700 selects the corresponding first and second calculation formulas based on the individual conditions input to the touch panel 710 and the hot and cold water conditions received from the remote control unit 600. The microcomputer 730 calculates the calories burned by the bather based on the selected first and second calculation formulas and the first and second bathing periods. This allows for a more accurate calculation of calories burned by taking into account the individual conditions and the hot and cold water conditions.

[0067] [others] Although the embodiments have been described above, the present disclosure is not limited to the above-described embodiments. The present disclosure also includes forms obtained by applying various modifications to the embodiments that would occur to those skilled in the art, or forms realized by arbitrarily combining the components and functions of the embodiments within the scope of the present disclosure.

[0068] For example, in the above embodiment, hot water supply system 100 has been exemplified as a case in which the calorie expenditure obtained by calculation is displayed on touch panel 710 (display unit) of display terminal 700. However, the calorie expenditure may also be displayed on touch panel 610 of remote control unit 600. In this case, the calorie expenditure calculated by display terminal 700 may be received by remote control unit 600 and then displayed on touch panel 610, or microcomputer 630 of remote control unit 600 may calculate the calorie expenditure and display the calculation result on touch panel 610.

[0069] In the above embodiment, the case where the calorie consumption is displayed on the display unit has been exemplified, but the history of the calorie consumption calculation results may be recorded on the display terminal 700, and the bather's health condition may be managed or estimated by analyzing this history on the display terminal 700. Furthermore, the calorie consumption calculation results may be transmitted to an external terminal different from the display terminal 700. In this case, the bather's health condition may be managed or estimated on an external terminal at, for example, a medical institution.

[0070] In the above embodiment, the different bathing conditions are exemplified by a state in which a micro-bubble generator generates micro-bubbles in the water in the bathtub. However, other different bathing conditions may also be employed. Examples of other different bathing conditions include a mist sauna, a waterfall bath, a whirlpool bath, and a mineral bath. A mineral bath is a bath in which mineral components (e.g., zinc oxide) are mixed into the water in the bathtub. Not only one of these different bathing conditions may be performed in a bathroom, but multiple different bathing conditions may also be performed in a bathroom. The hot water supply system is provided with at least one of a mist sauna device that performs a mist sauna, a waterfall bath device that performs a waterfall bath, a whirlpool bath, and a mineral bath device that performs a mineral bath, and each device is freely operable by a remote control unit 600. For each different bathing condition, a second calculation formula corresponding to the different bathing condition is determined in advance through experiments, simulations, etc., and calories burned are calculated based on the second calculation formula. This allows the calorie consumption to be calculated appropriately even in a variety of different bathing conditions.

[0071] Furthermore, the processing performed by a specific component in the embodiments may be performed by another component instead of the specific component. The order of multiple processes may be changed, or multiple processes may be performed in parallel.

[0072] Furthermore, the calorie consumption calculation method including the steps performed by each component of the hot water supply system may be executed by any device or system, i.e., the calorie consumption calculation method may be executed by the hot water supply system or by another device or system.

[0073] For example, the calorie expenditure calculation method may be executed by a computer including a processor, a memory, an input / output circuit, etc. In this case, the calorie expenditure calculation method may be executed by the computer executing a program for causing the computer to execute the calorie expenditure calculation method. Furthermore, the program may be recorded on a non-transitory computer-readable recording medium.

[0074] Furthermore, the multiple components of the hot water supply system may be configured with dedicated hardware, general-purpose hardware that executes the above-mentioned programs, or a combination of these. The general-purpose hardware may be configured with a memory that stores the programs and a general-purpose processor that reads and executes the programs from the memory. Here, the memory may be a semiconductor memory or a hard disk, and the general-purpose processor may be a CPU.

[0075] Furthermore, the dedicated hardware may be configured with a memory and a dedicated processor, etc. For example, the dedicated processor may refer to the memory and execute the calorie expenditure calculation method described above.

[0076] Each component of the hot water supply system may be an electric circuit. These electric circuits may form a single electric circuit as a whole, or may be separate electric circuits.
