Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, it is considered that it is a heavy burden for a house cleaning contractor to visit the house in advance and select the areas that need cleaning. In particular, in recent years, with the increasing demand for house cleaning services, there is a shortage of personnel for house cleaning contractors, so the above burden is considered to be particularly large.

[0005] Also, it is considered difficult for a house cleaning contractor to propose an appropriate house cleaning service to the resident of the house without visiting the house in advance.

[0006] The present invention has been made in view of the above problems, and the main object is to enable a house cleaning service provider to propose an appropriate house cleaning service while reducing the burden on the house cleaning service provider.

Means for Solving the Problems

[0007] In order to solve the above problems, a house cleaning support system according to a first invention is a house cleaning support system for supporting a house cleaning service provider who performs cleaning in a house, wherein a plurality of cleaning targets are predetermined in the house, for each of the cleaning targets, monitoring means for monitoring the situation in the cleaning target, cleaning necessity determination means for determining whether cleaning is necessary for each of the cleaning targets based on the monitoring result by the monitoring means, notification means for notifying the house cleaning service provider of the determination result of the cleaning necessity determination means, and is characterized by comprising the above.

[0008] According to the first invention, for each cleaning target in the house, the necessity of cleaning is determined, and the result of the determination is notified to the house cleaning service provider. In this case, the house cleaning service provider can grasp which of the cleaning targets in the house need cleaning without visiting the house. Therefore, without visiting the house, an appropriate proposal regarding the house cleaning service can be made to the resident. As a result, the house cleaning service provider can propose an appropriate house cleaning service while reducing their own burden.

[0009] A house cleaning support system according to a second invention is, in the first invention, wherein each of the cleaning targets includes equipment installed in the house, and as the monitoring means, it has equipment usage monitoring means for monitoring the usage situation of the equipment, The cleaning necessity determination means determines the necessity of cleaning for the facility based on the monitoring result by the facility usage monitoring means.

[0010] According to the second invention, it is considered that the degree of dirt of the facilities installed in the house changes depending on their usage status. For example, it is considered that the dirt of the facilities progresses as the usage frequency of the facilities increases. Therefore, in the second invention, paying attention to this point, the usage status of the facilities is monitored, and based on the monitoring result, the necessity of cleaning for the facilities is determined. Thereby, the necessity of cleaning the facilities can be suitably determined.

[0011] The house cleaning support system of the third invention is the first or second invention, wherein each cleaning target includes a first indoor space in the house, as the monitoring means, it has surface condition monitoring means for monitoring the surface condition which is the condition of the floor surface, wall surface or ceiling surface in the first indoor space, The cleaning necessity determination means determines the necessity of cleaning for the first indoor space based on the monitoring result by the surface condition monitoring means.

[0012] According to the third invention, the dirt in the indoor space of the house easily adheres to the floor surface, wall surface or ceiling surface of the indoor space. Therefore, in the third invention, the conditions of the floor surface, wall surface and ceiling surface of the indoor space are monitored, and based on the monitoring result, the necessity of cleaning for the indoor space is determined. Thereby, the necessity of cleaning the indoor space can be suitably determined.

[0013] The house cleaning support system of the fourth invention is any one of the first to third inventions, wherein each cleaning target includes a second indoor space in the house, as the monitoring means, it has behavior monitoring means for monitoring the behavior status of people in the second indoor space, The cleaning necessity determination means determines the necessity of cleaning for the second indoor space based on the monitoring result by the behavior monitoring means.

[0014] According to the fourth invention, it is considered that the degree of dirt in the indoor space depends on the movement status of the residents in that indoor space, the cleaning implementation status of the residents in the indoor space, etc., that is, the behavior status of the residents in the indoor space. Therefore, in the fourth invention, paying attention to this point, the necessity of cleaning for the indoor space is determined based on the behavior status of people in the indoor space. Thereby, the necessity of cleaning the indoor space can be suitably determined.

[0015] The house cleaning support system of the fifth invention, in any one of the first to fourth inventions, each of the cleaning targets includes a third indoor space in the house, as the monitoring means, it has furniture arrangement monitoring means for monitoring the arrangement status of furniture in the third indoor space, the cleaning necessity determination means determines the necessity of cleaning for the third indoor space based on the monitoring result by the furniture arrangement monitoring means.

[0016] According to the fifth invention, when new furniture is installed in the indoor space or the arrangement position of the furniture is changed, dust is likely to rise with the movement of the furniture. In that regard, according to the fifth invention, the necessity of cleaning is determined based on the furniture arrangement status. Therefore, when the furniture arrangement status changes, by making it determined that cleaning is required, such a determination result will be notified to the house cleaning contractor. Thereby, the house cleaning contractor can make a more appropriate proposal regarding house cleaning.

[0017] The house cleaning support system of the sixth invention, in any one of the first to fifth inventions, when a proposal to perform cleaning on the cleaning target determined to require cleaning is made to the resident of the house according to the determination result of the cleaning necessity determination means notified by the notification means, a acceptance / rejection information acquisition means for acquiring acceptance / rejection information regarding whether or not the proposal has been accepted by the resident, a change means for changing a determination reference value at the time of determining the necessity of cleaning for the cleaning target by the cleaning necessity determination means based on the acceptance / rejection information of the cleaning target acquired by the acceptance / rejection information acquisition means; It is characterized by comprising.

[0018] As described above, according to the first invention, the house cleaning contractor is notified of the result of determining the necessity of cleaning for each cleaning target of the house. In this case, the house cleaning contractor will make a proposal to the resident to perform cleaning on the cleaning target determined to require cleaning according to the notified determination result of necessity.

[0019] Therefore, in the sixth invention, acceptance / rejection information regarding whether or not the above proposal has been accepted by the resident is acquired, and based on the acquired acceptance / rejection information (of the cleaning target), the determination reference value at the time of determining the necessity of cleaning for the cleaning target by the cleaning necessity determination means is changed. In this case, for example, when information indicating that the proposal has been rejected is acquired as the acceptance / rejection information, it is possible that the resident has determined that the cleaning target is not yet dirty enough to be cleaned. Therefore, in such a case, the determination reference value can be automatically changed according to the resident's perception of cleanliness, such as changing the determination reference value to the side with lower cleanliness. As a result, in the subsequent determination of the necessity of cleaning, it is possible to perform a more accurate determination of necessity that reflects the resident's perception.

[0020] The house cleaning support system of the seventh invention is, in any of the first to sixth inventions, the house cleaning service provider provides a regular cleaning service of regularly visiting the house and performing cleaning, on each regular visit date before the house cleaning service provider visits the house, the cleaning necessity determination means determines the necessity of cleaning for each cleaning target each time, and notifies the house cleaning service provider of the result of the necessity determination by the notification means.

[0021] According to the seventh invention, when it is about to be the regular visit date when the house cleaning service provider who provides the regular cleaning service visits the house, each time, the result of the necessity of cleaning for each cleaning target in the house is notified to the house cleaning service provider. Thereby, the house cleaning service provider does not need to visit the house in advance for each regular visit date, and the burden when providing the regular cleaning service can be greatly reduced.

[0022] The house cleaning support system of the eighth invention is, in the seventh invention, provided with dirt determination means for determining that significant dirt has occurred on the cleaning target based on the monitoring result of the monitoring means, when the dirt determination means determines that significant dirt has occurred on the cleaning target, the cleaning necessity determination means determines that the necessity of cleaning for the cleaning target is high, when the cleaning necessity determination means determines that the necessity of cleaning is high, the notification means immediately notifies the house cleaning service provider to that effect.

[0023] According to the eighth invention, when significant dirt occurs on a cleaning target in a house, it is determined that the necessity of cleaning for that cleaning target is high. Then, this fact is immediately notified to the house cleaning service provider. In this case, when significant dirt occurs on a cleaning target, the house cleaning service provider can know this even if it is not the day before the regular visit. Therefore, the house cleaning service provider can timely propose to the resident to clean the cleaning target without waiting for the regular visit day.

[0024] The house cleaning support system of the ninth invention, in the eighth invention, when the cleaning necessity determination means determines that significant dirt has occurred on the cleaning target by the dirt determination means, it determines the necessity of cleaning for each cleaning target other than the cleaning target, The notification means is characterized in that when notifying that the necessity of cleaning for the cleaning target where the significant dirt has occurred is high, it also notifies the necessity of cleaning for each cleaning target other than the cleaning target accordingly.

[0025] According to the ninth invention, when significant dirt occurs on a cleaning target in a house, the necessity of cleaning for each cleaning target other than the cleaning target (hereinafter referred to as other cleaning targets) is determined. Then, when notifying the house cleaning service provider that the necessity of cleaning for the cleaning target where the significant dirt has occurred is high, the necessity of cleaning for other cleaning targets is also notified accordingly. Thereby, when the house cleaning service provider proposes to the resident to clean the cleaning target where the significant dirt has occurred, it is possible to also propose to clean other cleaning targets. For this reason, it is possible to also perform cleaning for other cleaning targets by utilizing this timing, and thereby, it can lead to a reduction in the burden on the house cleaning service provider, such as eliminating the cleaning visit on the next regular visit day.

Mode for Carrying Out the Invention

[0027] In the present embodiment, a house cleaning support system for assisting in providing services related to house cleaning is embodied for house cleaning contractors who provide house cleaning services for houses sold by a housing manufacturer. FIG. 1 is a diagram showing the overall configuration of the house cleaning support system. The house cleaning contractor is assumed to perform a so-called "regular cleaning service" in which the house is visited on a predetermined regular visit day to carry out house cleaning. When the house cleaning contractor visits the house on the regular visit day, first, the residents are proposed the locations to be cleaned on that day. Therefore, in the house cleaning support system of the present embodiment, the housing manufacturer provides information to the house cleaning contractor to support the above proposal before each regular visit day.

[0028] As shown in FIG. 1, the house cleaning support system 10 includes a server system 21 provided in the housing manufacturer 11. The server system 21 is composed of a personal computer and is connected to a house cleaning contractor 13 that provides a house cleaning service and a house 14 that has contracted for house cleaning via a communication network 15 such as the Internet. The server system 21 includes a control unit 22 configured with a well-known microcomputer having a CPU etc., a communication unit 23 that communicates via the communication network 15, an operation unit 24 operated by the housing manufacturer 11, and a storage unit 25 that stores various information.

[0029] A contractor server 31 is provided in the house cleaning contractor 13. The contractor server 31 is composed of a personal computer and is communicably connected to the server system 21 via the communication network 15.

[0030] The contractor server 31 includes a control unit 32 configured with a well-known microcomputer having a CPU etc., a communication unit 33 that communicates via the communication network 15, an operation unit 34 operated by the house cleaning contractor 13, a storage unit 35 that stores various information, and a display unit 36 on which various information related to house cleaning is displayed. Further, the communication unit 33, the operation unit 34, the storage unit 35, and the display unit 36 are respectively connected to the control unit 32.

[0031] A home server 41 is provided in the house 14. The home server 41 of the house 14 is composed of a personal computer and is communicably connected to the server system 21 via the communication network 15.

[0032] The home server 41 includes a control unit 42 configured with a well-known microcomputer having a CPU etc., a communication unit 43 that communicates via the communication network 15, an operation unit 44 operated by the resident, and a storage unit 45 in which various information is stored. The communication unit 43, the operation unit 44, and the storage unit 45 are respectively connected to the control unit 42.

[0033] In the house 14, a plurality of objects for house cleaning are set. The plurality of objects for house cleaning include the stove 17 as a facility, and the bathroom 18 and the living room 19 as indoor spaces. The stove 17, the bathroom 18, and the living room 19 are hereinafter sometimes collectively referred to as "cleaning targets 17 to 19".

[0034] Also, information regarding the cleaning targets within the house 14 is stored in advance in the storage unit 25 of the server system 21 as the specification information of the house 14. The specification information of the house 14 includes, for example, information such as "the house 14 has a living room 19", "the living room 19 is a target for cleaning", "a carpet is laid on the floor surface of the living room 19", and "a sofa is placed on the carpet". The house manufacturer 11 stores these information in the storage unit 25 by operating the operation unit 24. Therefore, the fact that the house 14 has the stove 17, the bathroom 18, and the living room 19, and that the stove 17, the bathroom 18, and the living room 19 are targets for cleaning, is stored in the server system 21 as the specification information of the house 14.

[0035] The stove 17 is a gas stove that obtains heat by using gas. It is assumed that the more the resident uses the stove 17, the more oil stains and the like accumulate around it. Therefore, the stove 17 is provided with a gas consumption sensor 51 that detects the gas consumption in the stove 17. The gas consumption in the stove 17 accumulates as the resident uses the stove 17. For this reason, the gas consumption sensor 51 can monitor the usage status of the stove 17 through the gas consumption. That is, the gas consumption sensor 51 corresponds to the facility usage monitoring means for monitoring the usage status of the stove 17. Note that the fact that the stove 17 is a gas stove is stored in the server system 21 in advance as the specification information of the house 14.

[0036] The gas consumption sensor 51 is connected to the home server 41. The monitoring results (gas consumption) from the gas consumption sensor 51 are sequentially input into the control unit of the home server 41. The control unit 42 accumulatively stores the input gas consumption in the storage unit 45. As a result, the home server 41 stores the gas consumption information, which is the cumulative value of the gas consumption in the stove 17.

[0037] Of the surfaces of the bathroom 18, the floor surface and the wall surface are made of interior materials with tiles pasted, and the ceiling surface is made of a resin panel with a water-repellent treatment. There is a risk of mold growth on the floor surface, wall surface and ceiling surface of the bathroom 18 due to the humidity inside the bathroom 18. Therefore, the bathroom 18 is provided with a camera 52 that photographs the surface conditions of the floor surface, wall surface and ceiling surface of the bathroom 18. The camera 52 photographs the floor surface, wall surface and ceiling surface of the bathroom 18 regularly (for example, at noon every day). Therefore, the occurrence status of mold and the like on the surface of the bathroom 18 can be monitored based on the image obtained by the camera 52. That is, the camera 52 corresponds to a surface condition monitoring means for monitoring the surface conditions in the bathroom 18. Note that the configurations of the floor surface, wall surface and ceiling surface of the bathroom 18 are stored in the server system 21 in advance as the specification information of the house 14.

[0038] The camera 52 is connected to the home server 41. The monitoring results (images of the surface conditions of the floor surface, wall surface and ceiling surface) from the camera 52 are input into the control unit 42 of the home server 41 regularly (for example, at noon every day). The control unit 42 sequentially stores the input monitoring results in the storage unit 45. As a result, the home server 41 stores the daily surface conditions in the bathroom 18.

[0039] In the living room 19, a carpet is laid on the floor surface, and over time, dirt accumulates on the surface of the carpet. It is considered that the degree of dirt on the carpet varies depending on the behavior status of the residents in the living room 19, such as the frequency of movement and cleaning of the residents. Therefore, the living room 19 is provided with a motion sensor 53 (equivalent to behavior monitoring means) for monitoring the behavior of the residents in the living room 19. Thereby, the behavior status of the residents in the living room 19 can be monitored. Regarding the fact that a carpet is laid in the living room 19, it is pre-stored in the server system 21 as the specification information of the house 14.

[0040] In the living room 19, it is considered that the larger the value of the air cleanliness in the living room 19, the easier it is for dust to accumulate. Therefore, the living room 19 is provided with an air cleanliness sensor 54 as monitoring means for monitoring the air cleanliness status in the living room 19. Thereby, the air cleanliness status in the living room 19 can be monitored.

[0041] In the living room 19, when a resident newly installs furniture or changes the furniture arrangement in the living room 19, it is considered that dust is likely to be raised along with the movement of the furniture. Therefore, the living room 19 is provided with a camera 55 (equivalent to furniture arrangement monitoring means) for monitoring the furniture arrangement status in the living room 19. Thereby, the furniture arrangement status in the living room 19 can be monitored. Regarding the furniture arrangement status in the living room 19, it is pre-stored in the server system 21 as the specification information of the house 14.

[0042] The motion sensor 53, the air cleanliness sensor 54, and the camera 55 are respectively connected to the home server 41. Monitoring results are sequentially input from the motion sensor 53, the air cleanliness sensor 54, and the camera 55 to the control unit 42 of the home server 41. The control unit 42 sequentially stores these input monitoring results in the storage unit 45. Thereby, the behavior status of the residents, the air cleanliness status, and the furniture arrangement status in the living room 19 are sequentially stored in the home server 41.

[0043] Note that the gas consumption sensor 51, cameras 52 and 55, motion sensor 53, and air cleanliness sensor 54 provided in the house 14 may hereinafter be collectively referred to as "monitoring means 51 to 55".

[0044] The server system 21 is connected to the home server 41 via the communication network 15. The server system 21 acquires the monitoring results by each of the monitoring means 51 to 55 via the home server 41. Specifically, the home server 41 transmits the monitoring results by each of the monitoring means 51 to 55 stored in the storage unit 45 to the server system 21 via the communication network 15. When the server system 21 receives the above monitoring results via the communication unit 23, it stores the monitoring results in the storage unit 25. In addition, the home server 41 transmits the monitoring results by the gas consumption sensor 51, cameras 52 and 55, and air cleanliness sensor 54 to the server system 21 once a month (for example, the last day of each month). The monitoring results by the motion sensor 53 and camera 55 are transmitted to the server system 21 sequentially.

[0045] When the arrangement status of the furniture in the living room 19 is changed, the server system 21 updates the arrangement status of the furniture stored in the storage unit 25 at any time based on the monitoring results of the camera 55. As a result, the arrangement status of the furniture stored in the server system 21 always reflects the latest status.

[0046] Here, the server system 21 (specifically, the control unit 22) of the housing manufacturer 11 creates a list 61 including information on the necessity of cleaning for each of the cleaning targets 17 to 19, and executes a notification control process for notifying the house cleaning contractor 13 of the list 61. Hereinafter, the flow of the notification control process will be described. As described above, the house cleaning contractor 13 visits the house 14 on a predetermined regular visit day to perform house cleaning. Specifically, the regular visit day of the house 14 is the first day of each month. Then, when the day before each regular visit day arrives, the housing manufacturer 11 notifies the house cleaning contractor 13 each time. The notification is to be made on the day before each regular visit day (in other words, the last day of each month). For this reason, the notification control process is executed on the last day of each month.

[0047] The notification control process includes a cleaning necessity determination process for determining the necessity of cleaning for each of the cleaning targets 17 to 19, a list generation process for generating a list 61 that lists the results of the cleaning necessity determination process for each of the cleaning targets 17 to 19, and a list transmission process for transmitting the list 61 to the house cleaning contractor 13. Note that the control unit 22 corresponds to a cleaning necessity determination means and a notification means.

[0048] First, the cleaning necessity determination process will be described. As shown in FIG. 2, in step S11, specification information of the house 14 is acquired from the storage unit 25. That is, it is grasped that the house 14 has cleaning targets 17 to 19 as targets for house cleaning. Then, the process proceeds to step S12.

[0049] In step S12, one determination target for the cleaning necessity determination process is selected from the cleaning targets 17 to 19. Then, the process proceeds to step S13.

[0050] In step S13, the monitoring result for the determination target selected in step S13 is acquired from the storage unit 25. At this time, the monitoring result within the most recent predetermined period is acquired. In this embodiment, the monitoring result for the period from immediately after the completion of the previous house cleaning to the execution of this process is acquired. That is, normally, the monitoring result for the most recent approximately one month is acquired. Then, the process proceeds to step S14.

[0051] In step S14, for the determination target selected in step S12, the cleaning necessity level is calculated based on the monitoring result acquired in step S13. The cleaning necessity level is an index for evaluating the necessity of cleaning according to the cleanliness for each of the cleaning targets 17 to 19, and a five-level scale from 1 to 5 is set. The necessity of cleaning is minimized when the cleaning necessity level is 1 (that is, the cleanliness is the highest), and maximized when the cleaning necessity level is 5 (that is, the cleanliness is the lowest). Since the calculation method of the value of the cleaning necessity level differs for each of the cleaning targets 17 to 19, it will be described in detail later. Subsequently, the process proceeds to step S15.

[0052] In step S15, it is determined whether or not the cleaning necessity level calculated in step S14 exceeds the determination reference value. The determination reference value is set for each of the cleaning targets 17 to 19. Therefore, for example, when the determination reference value is set to "cleaning necessity level: 3" for the determination target selected in step S12, if the cleaning necessity level of the said determination target is 4 or 5, a YES determination is made and the process proceeds to step S16. If the cleaning necessity level of the said determination target is 1, 2, or 3, a NO determination is made and the process proceeds to step S17.

[0053] In step S16, it is determined that "cleaning is required" for the determination target selected in step S12. Then, the cleaning required or not determination process ends.

[0054] In step S17, it is determined that "cleaning is not required" for the determination target selected in step S12. Then, the cleaning required or not determination process ends.

[0055] When the cleaning necessity determination process for a cleaning target is completed, the cleaning necessity determination process is subsequently executed for another cleaning target. That is, the cleaning necessity determination process is sequentially executed for each cleaning target. Finally, the determination of whether cleaning is necessary is made for all cleaning targets 17 to 19.

[0056] Note that the determination reference value corresponds to the criterion for the resident to determine whether cleaning is necessary for each cleaning target 17 to 19. The determination reference value is stored in the storage unit 25 prior to the cleaning necessity determination process, and the housing manufacturer 11 can set an arbitrary value. The housing manufacturer 11 assumes a high level of cleanliness such that the resident determines that "cleaning should be performed" for the cleaning target, and sets the determination reference value based on this.

[0057] When the cleaning necessity determination process is completed for all cleaning targets 17 to 19, the list generation process is subsequently executed. In the list generation process, based on the results of the above-described cleaning necessity determination process, a list 61 listing the cleaning necessity of each cleaning target 17 to 19 is generated. Then, the generated list 61 is stored in the storage unit 25. As the list 61, for each of the cleaning targets 17 to 19, a column for "cleaning required" and a column for "cleaning not required" are provided, and it is assumed that the corresponding column is checked (see Figure 3).

[0058] Subsequently, the list transmission process is executed. In the list transmission process, the server system 21 transmits the list 61 to the contractor server 31 via the communication network 15. Thereafter, the notification control process by the server system 21 ends. In this embodiment, the notification control process is automatically started at a fixed time on the last day of each month, and the transmission of the list 61 is completed on that day.

[0059] The house cleaning contractor 13 receives the list 61 from the housing manufacturer 11. Specifically, when the contractor server 31 (control unit 32) receives the list 61 through the communication unit 33, it stores the list 61 in the storage unit 35 and displays on the display unit 36 that the list 61 has been received. The house cleaning contractor 13 can operate the operation unit 34 to display the list 61 on the display unit 36 and check the content of the list 61. Thereby, the house cleaning contractor 13 can, based on the list 61, consider the content to be proposed to the resident on the visit date.

[0060] Subsequently, return to the description of the cleaning necessity determination process. As described above, the method for calculating the cleaning necessity executed in step S14 differs for each of the cleaning targets 17 to 19. Here, the method for calculating the cleaning necessity will be described for each of the cleaning targets 17 to 19. The cleaning necessity for the cleaning targets 17 to 19 can be calculated by the following processes (a) to (f).

[0061] (a) For the stove 17, based on the monitoring result by the gas usage sensor 51, the cleaning necessity can be calculated. Specifically, the larger the cumulative value of the gas usage, the more times the stove 17 is used, and it is considered that the accumulation of dirt is progressing. Therefore, for the stove 17, the larger the cumulative value of the gas usage in the most recent approximately one month, the larger the value of the calculated cleaning necessity.

[0062] (b) For the bathroom 18, based on the monitoring result by the camera 52 (the surface condition of the bathroom 18), the cleaning necessity can be calculated. In this case, for example, when mold growth progresses at the joint part of the tiles in the bathroom 18, it is considered that the brightness of the joint part in the image becomes lower (more blackish). Therefore, for the bathroom 18, in the image of the surface condition of the bathroom 18 acquired by the camera 52, the lower the brightness of the tile joint part, the larger the value of the calculated cleaning necessity.

[0063] (c) Regarding the living room 19, the cleaning necessity can be calculated based on the monitoring result (the behavior status of the residents) by the motion sensor 53. In this case, for example, from the behavior status of people in the living room 19, predetermined behaviors that affect the cleaning degree of the living room 19 are extracted by analysis. The predetermined behaviors include the implementation of cleaning in the living room 19 (the behavior of cleaning the living room 19) and the movement of residents in the living room 19 (the behavior of soiling the living room 19), etc. And the cleaning necessity of the living room 19 is calculated as a smaller value as the number of behaviors of cleaning the living room 19 extracted in the most recent approximately one month is larger, and is calculated as a larger value as the number of behaviors of soiling the living room 19 extracted is larger.

[0064] (d) Regarding the living room 19, the cleaning necessity can also be calculated based on the monitoring result (air cleanliness) by the air cleanliness sensor 54. In this case, for example, if there is a lot of dust in the living room 19, it is considered that the value of the air cleanliness will increase. Therefore, the cleaning necessity of the living room 19 is calculated as a larger value as the value of the air cleanliness obtained by the air cleanliness sensor 54 is larger.

[0065] (e) Regarding the living room 19, the cleaning necessity can also be calculated based on the monitoring result (the furniture arrangement status) by the camera 55. In this case, for example, when the resident moves the furniture, it is considered that dust is likely to be raised in the living room 19. Therefore, if a change in the furniture arrangement status is confirmed through the camera 55 in the most recent approximately one month, it is considered that the movement of the furniture has occurred. In this case, the cleaning necessity of the living room 19 is calculated as a larger value. Also, as the number of times the change in the furniture arrangement status is confirmed in the most recent approximately one month is larger, the cleaning necessity is calculated as a larger value. Note that whether the resident has moved the furniture can also be confirmed by extracting the operation of moving the furniture as predetermined behavior information from the behavior information obtained by the above-mentioned motion sensor 53.

[0066] Regarding the cleaning necessity of the living room 19, there are three calculation methods (c) to (e) above. Among (c) to (e), you may calculate by any one of the methods, or you may calculate by combining multiple methods.

[0067] Also, it is considered that the ease of soiling progression of the cleaning target varies depending on the state of the cleaning target. For example, if the facility is waterproofed, it is considered that dirt is less likely to adhere. If the floor surface of the indoor space is carpeted, it is considered that dust accumulates more easily than in the case of flooring. When a shelf is arranged near the wall surface of the indoor space, it is considered that dust easily accumulates between the shelf and the wall surface. Therefore, in calculating the cleaning necessity of each cleaning target 17 to 19, it is preferable to perform analysis based on the specification information of the house 14 stored in the storage unit 25. At this time, in this embodiment, the specification information related to the living room 19 is updated based on the monitoring result by the camera 55 of the living room 19. Thereby, it is possible to suppress the occurrence of problems in the analysis process based on the specification information of the house 14 due to, for example, pattern replacement of the living room 19.

[0068] By the way, regarding the residents' perception of cleanliness, it is considered that there are individual differences, for example, whether the resident likes cleanliness or not. Therefore, even if the house cleaning contractor 13 makes a proposal to the resident based on the list 61 provided by the house manufacturer 11, it is assumed that the proposal may not be accepted by the resident depending on the resident's perception. For example, even when the server system 21 determines that "cleaning is required" for a certain cleaning target, if the resident does not care much about dirt, it is considered that the resident may reject the implementation of cleaning. Also, even when the server system 21 determines that "cleaning is not required", if the resident likes cleanliness, it is considered that the resident may request the implementation of cleaning.

[0069] Therefore, in this embodiment, the server system 21 is configured to obtain proposal acceptance / rejection information regarding whether a proposal made based on the list 61 has been accepted by the residents. Then, based on the obtained proposal acceptance / rejection information, a process is performed to improve the cleaning necessity determination. As a result, when creating the next plan, a plan that is more acceptable to the residents can be created. In the following description, the process of improving the cleaning necessity determination based on the proposal acceptance / rejection information is referred to as the "necessity determination improvement process".

[0070] First, prior to the necessity determination improvement process, after the house cleaning contractor 13 has cleaned the house 14, the house cleaning contractor 13 reports to the house manufacturer 11 the proposal acceptance / rejection information regarding the proposal made during the cleaning. Specifically, the house cleaning contractor 13 operates the operation unit 34 of the contractor server 31 to input the proposal acceptance / rejection information for each of the cleaning targets 17 to 19. The contractor server 31 transmits the proposal acceptance / rejection information to the server system 21 via the communication network 15. Note that the operation unit 34 of the contractor server 31 corresponds to the acceptance / rejection information acquisition means.

[0071] When inputting the proposal acceptance / rejection information, the house cleaning contractor 13 inputs it into a predetermined result form 62 (see FIG. 4). All the cleaning targets 17 to 19 are listed in the result form 62, and for each of the cleaning targets 17 to 19, a "Proposal Existence" column, an "Adoption" column, and a "Non-Adoption" column are provided. In the "Proposal Existence" column, "Yes" is entered if a proposal to clean the residence has been made to the resident based on the list 61, and "No" is entered if no proposal has been made. In the "Adoption" column and the "Non-Adoption" column, one of the columns is checked depending on whether the proposal based on the list 61 has been accepted.

[0072] Specifically, the house cleaning service provider 13 proposes to clean the cleaning targets marked as "Needs Cleaning" in List 61. If the proposal to clean is accepted by the residents, for the relevant cleaning targets, "Yes" is entered in the "Proposal Existence" column and a checkmark is placed in the "Adoption" column. On the other hand, if the proposal to clean is made but the residents reject the cleaning, for the relevant cleaning targets, "Yes" is entered in the "Proposal Existence" column and a checkmark is placed in the "Non-Adoption" column.

[0073] Also, for cleaning targets marked as "Does Not Need Cleaning" in List 61 (i.e., cleaning targets for which no proposal to clean was made), if the residents additionally request the cleaning of the relevant cleaning targets, the house cleaning service provider 13 enters "No" in the "Proposal Existence" column and places a checkmark in the "Non-Adoption" column for the relevant cleaning targets. On the other hand, if there is no additional request from the residents for cleaning targets marked as "Does Not Need Cleaning" in List 61, "No" is entered in the "Proposal Existence" column and a checkmark is placed in the "Adoption" column.

[0074] Subsequently, when the server system 21 (control unit 22) receives the proposal acceptance / rejection information through the communication unit 23, it associates and stores it in the storage unit 25 with the house 14 and List 61, and starts the necessity determination improvement process. Hereinafter, the flow of the necessity determination improvement process will be described based on FIG. 5. The necessity determination improvement process is executed for each cleaning target 17 - 19. In the following description, as an example, the necessity determination improvement process related to the stove 17 among the cleaning targets 17 - 19 of the house 14 will be described.

[0075] In step S21, a target for which the necessity determination improvement process is to be performed is selected. Specifically, the stove 17 is selected as the target. Subsequently, the process proceeds to step S22.

[0076] In step S22, the proposal acceptance / rejection information regarding the stove 17 is acquired from the storage unit 25. Subsequently, the process proceeds to step S23.

[0077] In step S23, it is determined whether the stove 17 was marked as "Needs cleaning" in the list 61. If it was marked as "Needs cleaning", a YES determination is made and the process proceeds to step S24. If it was marked as "Does not need cleaning", a NO determination is made and the process proceeds to step S27.

[0078] In step S24, based on the proposal acceptance / rejection information regarding the stove 17, it is determined whether the proposal to clean the stove 17 was accepted by the resident. If the proposal acceptance / rejection information regarding the stove 17 is "Adopted", that is, if the proposal to clean the stove 17 was accepted, a YES determination is made and this process ends. That is, it is determined that the determination of whether the stove 17 needs cleaning was appropriate, and the subsequent determination of whether cleaning is required will be executed as it is. Also, if the proposal acceptance / rejection information regarding the stove 17 is "Not adopted", that is, if the proposal to clean the stove 17 was not accepted, a NO determination is made and the process proceeds to step S25.

[0079] In step S25, the determination reference value for determining whether the stove 17 needs cleaning is changed to a value larger than the current value. If, in spite of the proposal to clean the stove 17, the resident did not adopt the proposal, the resident may have judged that "the stove 17 is not dirty enough to be cleaned yet". In this case, since it is presumed that the resident does not require such a high level of cleanliness for the stove 17, it is considered that the frequency of cleaning the stove 17 should be lower than the current level. Therefore, in step S25, the determination reference value for determining whether the stove 17 needs cleaning is changed to a value larger than the current value (that is, the side with a lower cleanliness level). Thereby, it is possible to make it less likely to determine that the stove 17 "needs cleaning" compared to the current situation. Then, this process ends. Note that the control unit 22 corresponds to the changing means.

[0080] On the other hand, in step S27, when the stove 17 is set as "not requiring cleaning" in the list 61, it is determined whether the cleaning of the stove 17 is requested by the residents. If the proposal acceptance / rejection information related to the stove 17 is "accepted", that is, if the residents do not request the cleaning of the stove 17, a YES determination is made and this process ends. That is, it is determined that the determination of whether the stove 17 requires cleaning was appropriate, and the subsequent determination of whether cleaning is required will be executed as it is. Also, if the proposal acceptance / rejection information related to the stove 17 is "rejected", that is, if the residents request the cleaning of the stove 17, a NO determination is made and the process proceeds to step S28.

[0081] In step S28, the determination reference value for determining whether the stove 17 requires cleaning is changed to a value smaller than the current value. If the residents request the cleaning of the stove 17 even though the cleaning of the stove 17 has not been proposed, the residents may have determined that "the stove 17 is dirty to a level that requires cleaning". In this case, since it is presumed that the residents are demanding a relatively high level of cleanliness for the stove 17, it is considered that the frequency of cleaning the stove 17 should be higher than the current level. Therefore, in step S28, the determination reference value for determining whether the stove 17 requires cleaning is changed to a value smaller than the current value (that is, the side with higher cleanliness). Thereby, it can be made easier to determine that the stove 17 "requires cleaning" compared to the current situation. Then, this process ends.

[0082] By the way, in this embodiment, house cleaning is carried out on the regular visit day once a month. However, there may be cases where it is desired to clean the cleaning target without waiting for the regular visit day, such as when significant dirt occurs on the cleaning target in the house. For example, as described above, a carpet is laid on the floor surface of the living room 19. Therefore, if the resident spills a drink or the like in the living room 19, it is assumed that significant dirt will occur on the carpet and urgent cleaning will be required.

[0083] Here, in this embodiment, the server system 21 (control unit 22) can determine that significant dirt has occurred on the cleaning target based on the monitoring result of the monitoring means. That is, the control unit 22 corresponds to the dirt determination means. As described above, the behavior information of the resident acquired by the motion sensor 53 is sequentially transmitted to the server system 21 via the home server 41 and stored in the storage unit 25. Then, the server system 21 immediately executes the analysis process of the behavior information of the resident.

[0084] In addition, when the server system 21 determines that "significant dirt has occurred" on the cleaning target, it determines that "cleaning is required" for the cleaning target. And in this case, it immediately sends a notice to that effect to the contractor server 31. When the contractor server 31 receives the notice, the content of the notice can be displayed on the display unit 36. Thereby, the house cleaning contractor 13 can know immediately after the occurrence of the significant dirt that the cleaning target has become in a state where cleaning is necessary due to the occurrence of significant dirt.

[0085] As a specific example, first, when a resident spills a drink or the like in the living room 19, the motion of the resident at that time is acquired by the motion sensor 53 as the behavior information of the resident. The monitoring result by the motion sensor 53 is sequentially transmitted to the server system 21 via the home server 41. Therefore, the behavior information is immediately transmitted to the server system 21.

[0086] When the server system 21 receives the behavior information of the resident acquired by the motion sensor 53, it immediately executes the analysis process of the behavior information of the resident. The server system 21 is set to determine whether the resident has performed an action of spilling a drink or the like in the living room 19, and if it is determined that there is such a spilling action, it is determined that "significant dirt has occurred" for the living room 19. Therefore, when the resident spills a drink or the like in the living room 19, the server system 21 determines that "significant dirt has occurred" for the living room 19.

[0087] Subsequently, the server system 21 determines that the living room 19 "needs cleaning". Then, the server system 21 immediately sends a notification to the merchant server 31 stating that "the carpet in the living room 19 has significant dirt due to the resident spilling a drink or the like and is in a state that requires cleaning". Then, the house cleaning merchant 13 can know this without waiting for the day before the regular visit date (the last day of each month) by looking at the display unit 36 of the merchant server 31.

[0088] In this way, when significant dirt occurs on the cleaning target, the house cleaning merchant 13 can know this even if it is not before the regular visit date. Therefore, a timely proposal to clean the cleaning target can be made to the resident without waiting for the regular visit date.

[0089] Also, when the control unit 22 determines that "significant dirt has occurred" for the living room 19, it determines that the living room 19 "needs cleaning", but it is also advisable to determine whether other cleaning targets 17, 18 need cleaning as well. At this time, for the other cleaning targets 17, 18, the determination of whether cleaning is required will be made by the cleaning required determination process using the above-mentioned cleaning necessity degree and determination reference value.

[0090] Then, when the control unit 22 notifies the house cleaning contractor 13 that the cleaning necessity of the living room 19 where significant dirt has occurred is high, it also notifies the cleaning necessity for each of the other cleaning targets 17 and 18 accordingly. As a result, when the house cleaning contractor 13 proposes cleaning of the living room 19 where significant dirt has occurred to the resident, it becomes possible to also propose cleaning for the other cleaning targets 17 and 18.

[0091] Note that the service form in which the house cleaning service can be used not regularly but on a spot basis as described above is sometimes generally called the "spot cleaning service". That is, in this embodiment, residents can use both the regular cleaning service and the spot cleaning service.

[0092] According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

[0093] · The server system 21 of the housing manufacturer 11 determines the necessity of cleaning for each of the cleaning targets 17 to 19 in the house 14 and notifies the house cleaning contractor 13 of the result of the determination. In this case, the house cleaning contractor 13 can grasp which of the cleaning targets 17 to 19 in the house 14 need cleaning without visiting the house 14. Therefore, without visiting the house 14, it is possible to make an appropriate proposal regarding the house cleaning service to the resident. As a result, the house cleaning contractor 13 can make an appropriate proposal for the house cleaning service while reducing its own burden.

[0094] Also, it is convenient for the resident when the time the house cleaning contractor 13 stays in the house 14 is shortened.

[0095] · The degree of soiling of the stove 17 is considered to vary depending on its usage situation. For example, it is considered that the more frequently the stove 17 is used, the more the equipment gets soiled. Focusing on this point, the usage situation of the stove 17 is monitored by the gas consumption sensor 51, and based on the monitoring result, it is determined whether the stove 17 needs to be cleaned. Thereby, it is possible to suitably determine whether the stove 17 needs to be cleaned.

[0096] · The dirt in the bathroom 18 is likely to adhere to the floor surface, wall surface, and ceiling surface of the bathroom 18. Therefore, the situation of the floor surface, wall surface, and ceiling surface of the bathroom 18 is monitored by the camera 52, and based on the monitoring result, it is determined whether the bathroom 18 needs to be cleaned. Thereby, it is possible to suitably determine whether the bathroom 18 needs to be cleaned.

[0097] · The degree of soiling of the living room 19 is considered to depend on the movement situation (e.g., movement frequency) of the residents in the living room 19 and the cleaning implementation situation (e.g., cleaning frequency) of the residents in the indoor space. Focusing on this point, based on the behavior situation of people in the living room 19 obtained by the motion sensor 53, it is determined whether the living room 19 needs to be cleaned. Thereby, it is possible to suitably determine whether the living room 19 needs to be cleaned.

[0098] · When new furniture is installed or the arrangement position of the furniture is changed in the living room 19, dust is likely to be raised along with the movement of the furniture. In that regard, based on the furniture arrangement situation obtained by the camera 55, it is determined whether cleaning is necessary. Therefore, when the furniture arrangement situation changes, by making it easier to determine that cleaning is required, such a determination result is notified to the house cleaning service provider 13. Thereby, the house cleaning service provider 13 can make a more appropriate proposal regarding house cleaning.

[0099] · If the furniture arrangement in the living room 19 changes, for example, it is considered that the soiling tendency of the living room 19 may change, such as dust accumulating easily between the wall surface of the living room 19 and the newly installed furniture. Here, based on the furniture arrangement status acquired by the camera 55, the specification information of the house 14 stored in the storage unit 25 is sequentially updated. As a result, for the living room 19, a more accurate determination of whether cleaning is required, reflecting the latest furniture arrangement status, becomes possible.

[0100] · The server system 21 notifies the house cleaning service provider 13 of the results of the determination of whether cleaning is required for each cleaning target 17 - 19 of the house 14 as a list 61. In this case, the house cleaning service provider 13 makes a proposal to the resident to perform cleaning on the cleaning target determined to require cleaning according to the results of the determination of whether cleaning is required notified by the list 61.

[0101] Therefore, the house cleaning service provider 13 operates the service provider server 31 to input proposal acceptance / rejection information regarding whether the above proposal has been accepted by the resident into the result table 62. The result table 62 is transmitted from the service provider server 31 to the server system 21. As a result, the server system 21 can acquire the proposal acceptance / rejection information related to each cleaning target 17 - 19.

[0102] Then, based on the obtained proposal acceptance / rejection information (result table 62), the server system 21 changes the judgment reference value at the time of the necessity judgment by the necessity judgment means for the cleaning target. In this case, for example, when information indicating that a proposal to perform cleaning has been rejected is obtained as the proposal acceptance / rejection information, there is a possibility that the resident has determined that the cleaning target is not yet dirty enough to be cleaned. Therefore, in such a case, the judgment reference value can be automatically changed according to the resident's perception of cleanliness, such as changing the judgment reference value related to the cleaning target to the side with a lower cleanliness level. As a result, in the subsequent judgment of the necessity of cleaning, it becomes possible to perform a more accurate necessity judgment that reflects the resident's perception.

[0103] · The house cleaning contractor 13 provides a regular cleaning service and visits the house 14 for cleaning on the first day of each month. Therefore, when the day before the regular visit date (the last day of each month) arrives, the server system 21 notifies the house cleaning contractor 13 of the results of the necessity of cleaning for each cleaning target 17 to 19 in the house 14 each time. As a result, the house cleaning contractor 13 does not need to pre-visit the house 14 for each regular visit date, and the burden of providing the regular cleaning service can be significantly reduced.

[0104] · Even when providing a regular cleaning service, if significant stains occur on the cleaning targets within the house 14, such as when a resident spills a drink or the like in the living room 19, it is preferable to promptly perform the cleaning. Therefore, the home server 41 determines whether there has been an operation of spilling a drink or the like in the living room 19 based on the monitoring result by the motion sensor 53. And when it is determined that there has been an operation of spilling a drink or the like in the living room 19, it is determined that the cleaning necessity for the living room 19 is high, and this is immediately notified to the house cleaning contractor 13. In this case, when significant stains occur in the living room 19, the house cleaning contractor 13 can know this even before the regular visit date. Therefore, a proposal to clean the living room 19 can be timely made to the resident without waiting for the regular visit date.

[0105] Also, the monitoring result by the motion sensor 53 is sequentially transmitted to the home server 41 and is immediately analyzed by the home server 41. For this reason, even when significant stains suddenly occur, the house cleaning contractor 13 can promptly respond.

[0106] · When the home server 41 determines that significant stains have occurred in the living room 19, it also determines the necessity of cleaning for other cleaning targets 17, 18 accordingly. And when notifying the house cleaning contractor 13 that the cleaning necessity for the living room 19 with significant stains is high, the necessity of cleaning for other cleaning targets 17, 18 is notified accordingly. Thereby, when the house cleaning contractor 13 makes a proposal to clean the living room 19 with significant stains to the resident, it becomes possible to also make a proposal to clean other cleaning targets. For this reason, it becomes possible to also perform the cleaning for other cleaning targets 17, 18 in conjunction with this timing, which can lead to a reduction in the burden on the house cleaning contractor 13, such as making the next regular visit cleaning visit unnecessary.

[0107] The present invention is not limited to the above-described embodiments, and may be implemented, for example, as follows.

[0108] (1) In the above-described embodiment, the equipment to be cleaned assumes the stove 17, but is not limited thereto. For example, an air conditioner, a ventilation fan (range hood), a water heater, etc. are also assumed. In the case of an air conditioner, it is conceivable to estimate the degree of dirt on the filter by an air cleanliness sensor. In the case of a ventilation fan, it is conceivable to monitor the operating status by a power consumption sensor. In the case of a water heater, it is conceivable to monitor the operating status by a gas usage sensor or a water usage sensor.

[0109] Also, in the above-described embodiment, the stove 17 was a gas stove, but it may be an IH stove. In this case, by using a power consumption sensor instead of the gas usage sensor 51, the usage status can be monitored. Thus, the monitoring means is not limited to that of the above-described embodiment either.

[0110] (2) In the above-described embodiment, the equipment to be cleaned assumed the bathroom 18 and the living room 19, but is not limited thereto. For example, a toilet etc. are also assumed. It is considered that the more frequently the residents use the toilet, the more easily it gets dirty. Therefore, as an example, it is conceivable to provide an infrared sensor (corresponding to equipment usage monitoring means) for detecting the presence or absence of residents in the toilet and monitor the number of times the toilet is used by the residents.

[0111] (3) In the above-described embodiment, in the most recent approximately one month, the more frequently the residents clean the living room 19, the smaller the cleaning necessity value is calculated. However, when the floor surface of the living room 19 is flooring, it is also conceivable that the floor surface is easily soiled due to a lack of wax on the flooring surface, and as a result, the frequency of wiping the floor by the residents is high. In this case, it is considered preferable to propose waxing of the flooring based on the high frequency of floor wiping.

[0112] Therefore, in a house where such a situation is assumed, it may be better to calculate a larger cleaning necessity value as the residents perform more actions to clean the living area 19. In this case, for example, regarding the frequency of floor wiping by the residents, if the recent frequency is higher than the frequency immediately after waxing when comparing the two, wax shortage is suspected. When such a tendency is observed, by calculating a larger value for the cleaning necessity of the living area based on the increasing tendency of the floor wiping frequency, more appropriate proposals can be made to the residents.

[0113] (4) In the above embodiment, the proposal acceptance / rejection information was to be input by the house cleaning contractor 13, but it may be input by the residents instead. In this case, it is assumed that the residents operate the operation unit 24 of the home server 41 to input.

[0114] (5) In the above embodiment, the cleaning necessity for each of the cleaning targets 17 - 19 was described in the list 61, but other information may be described instead. For example, reference information regarding the cleaning target such as "Spider webs are seen on the ceiling and wall surfaces of the bathroom 18" may be described. Thereby, the house cleaning contractor 13 can make a more accurate cleaning proposal to the residents.

[0115] (6) In the above embodiment, the result table 62 was to select whether the proposed cleaning should be accepted or not, but other information may be described instead. For example, the result of a direct hearing by the house cleaning contractor 13 from the residents such as "There is a request from the residents to reduce the cleaning frequency of the stove 17" may be described. Thereby, the housing manufacturer 11 can more finely grasp the individual circumstances of each house based on the hearing result, and thus improve the accuracy of the cleaning necessity determination.

[0116] (7) In the above-described embodiment, the determination reference value was automatically changed by the home server 41 based on the proposal acceptance / rejection information. However, the housing manufacturer 11 may operate the operation unit 24 to change it.

[0117] (8) In the above-described embodiment, the case where the regular cleaning service and the spot cleaning service are used in combination was assumed. However, the combined use is not essential.

[0118] (9) In the above-described embodiment, when providing the spot cleaning service to clean the cleaning target (living room 19) determined to have "significant dirt", the necessity of cleaning was also determined for the other cleaning targets 17 and 18 as well. As a result, when proposing to the resident to clean the living room 19 where significant dirt has occurred, it is possible to also propose cleaning for the other cleaning targets 17 and 18.

[0119] However, for a house cleaning contractor who wants to minimize the number of business trips as much as possible, it is considered more preferable that there are more cleaning targets to be cleaned in one visit. Here, regarding the determination reference value related to the necessity of cleaning, when applying it to other cleaning targets when providing the spot cleaning service, a different one from the normal one may be applied.

[0120] Specifically, the determination reference value in the above-described embodiment is the first determination reference value. The determination reference value has a first reference value and a second determination reference value smaller than the first determination reference value. When it is determined that significant dirt has occurred on a cleaning target, the home server 41 determines the necessity of cleaning for each cleaning target other than that cleaning target based on the second determination reference value. As a result, it becomes easier for the other cleaning targets to be determined as "requiring cleaning". Therefore, the house cleaning contractor 13 can propose cleaning for more cleaning targets when providing the spot cleaning service.
