BACKGROUND OF THE INVENTION
The present invention relates to a system that is mounted on a vehicle and used for bathing service at a visit destination.
[0002]
[Prior art]
Japanese Patent Application No. 8-14015 discloses such a system, and FIG. 5 illustrates an example thereof.
[0003]
Tap water is supplied to the hot water tank 1 shown in FIG. Alternatively, hot water boiled using midnight power is supplied to the hot water tank 1.
[0004]
The tap water supplied into the hot water tank 1 is heated by the heater 2 to about 85 ° C. with late-night power. Excessive temperature rise is prevented by using the thermostat 3, and the thermostat 4 is provided as a spare for the thermostat 3. The hot water in the hot water tank 1 is kept warm, and the amount thereof is confirmed by a water level gauge 5.
[0005]
When the vehicle arrives at the bathing service destination, hot water in the hot water tank 1 is mixed with tap water by the hot water automatic temperature control mixing valve 6, and the bath water thus obtained is sent from the pump 7 to the bathtub outside the vehicle. Is done.
[0006]
The shortage of hot water in the hot water tank 1 is detected by the electrode rod 8, and the pump 7 is stopped and controlled by the control panel 9 at that time.
[0007]
According to the above example, since electricity is used for the heat source, a bathing service can be performed cleanly and safely. In addition, the bathing service can be started promptly after arrival because it goes to the care recipient's house while keeping the hot water warm. Furthermore, since the inexpensive late-night power is used, the running cost of the system is greatly reduced.
[0008]
[Problems to be solved by the invention]
Bathing services are performed mainly by women, and in many cases, the car is driven by a female caregiver. The vehicle is equipped with a dedicated bathtub and is carried to the home of the care recipient.
[0009]
Each time a bathing service is performed, about 200 liters of bath water at about 40 ° C. including a shower is used. For this reason, it is assumed that 1200 liters of bath water of about 40 ° C. is necessary per day, and when converted to 85 ° C. hot water, the amount is 500 liters.
[0010]
However, vehicles that can be equipped with a 500 liter electric water heater (hot water tank 1) and a bathtub are limited to large vehicles in terms of weight and space, and it is often necessary to operate in a small place at a visiting place or the like. For this reason, ordinary female caregivers cannot drive vehicles, and skilled dedicated drivers must be secured separately from the caregivers.
[0011]
The present invention has been made in view of the above circumstances, and can be mounted on a small vehicle that can be easily driven by a normal female caregiver, and uses a sufficient amount of bath water at an optimal temperature while suppressing an increase in initial cost. The purpose is to provide in-vehicle equipment that can be used for traveling bathing services.
[0012]
[Means for Solving the Problems]
In order to solve the above-described object, the system according to the present invention includes an electric water heater having a capacity of about 250 liters, which is assumed to be equivalent to half a day for bathing services, and normal temperature water and hot water provided in the electric water heater from the outside of the vehicle. Water heaters, heaters that heat room-temperature water supplied to electric water heaters with late-night power, bathtubs that are taken to the care recipient's home at bathing service visits, and hot water Hot water pump that pumps hot water from the water heater, hot water pumped from the electric water heater with hot water pump and room temperature water supplied from outside the car mixes bath water at a temperature that will not cause burns to the care recipient Remaining in the electric water heater, the automatic mixing valve to be generated, the manual mixing valve that is installed in the bathtub and mixes the hot water discharged from the automatic mixing valve and the room temperature water supplied from outside the vehicle in proportion to the manual operation Bathing care for the amount of hot water To the bathing caregiver when hot water from the electric water heater is pumped out to the required amount of bathing for one cared person. It is characterized by on-vehicle equipment used for a patrol bath service mounted on a small car .
[0013]
A bathing service using this type of system is performed for six care recipients per day and is divided equally into three people in the morning and afternoon, and the vehicle returns to the center at lunch time.
[0014]
Therefore, in the present invention, the system is configured such that the electric water heater has a capacity corresponding to half a day of the bathing service and can be mounted on a small vehicle including the bathtub. Hereinafter, the present invention will be described more specifically in accordance with an actual operation mode.
[0015]
On the day before the bathing service is performed, tap water or the like is injected into the electric water heater, and the water in the electric water heater is heated with a heater using midnight power. Prepare hot water on the vehicle. Also, hot water for half a day will be prepared at the bathing service center.
[0016]
On the day of the bathing service, 3 people are visited in the morning and in the afternoon, returning to the center in the daytime, and hot water is supplied to the electric water heater using the free time of the day to prepare for the afternoon work.
[0017]
At the place of visit, the caregiver supplies bath water at a temperature at which the cared person does not suffer burns from the automatic mixing valve to the bathtub at the time of bathing, and the temperature of the bath water is finely adjusted by operating the manual mixing valve.
[0018]
However, the amount of hot water used in the electric water heater differs depending on the caregiver, the cared person, etc., and it is assumed that the cared person who uses the next bathing service will use it. Especially in winter, the water temperature is low and there is a high probability that hot water will be insufficient. In the winter in extremely cold regions, the temperature of the hot water drops considerably before reaching the bathtub, and an absolute amount of hot water is expected to be insufficient.
[0019]
For this reason, a chasing device for heating the tap water supplied to the electric water heater is provided. In addition, when hot water of the electric water heater is used in the bathing service up to the required bathing amount for one cared person, an alarm is issued to the caregiver who is performing the bathing service.

It is confirmed by the output of the remaining hot water amount indicator 114 that the remaining hot water has reached 75 liters, the remaining hot water amount indicator 114 calculates and displays the remaining amount of hot water from the output of the flow sensor 116, and the flow sensor 116 displays hot water. A downstream flow rate of the pump 18 is detected.
[0041]
In fact, the alarm 112 has a built-in lamp and transmitter, and the caregiver has a receiver. When the remaining hot water level reaches 75 liters, the alarm 112 will be alerted by the intermittent buzzer and lighting of the lamp. When the receiver reaches 10 liters, the receiver in the caregiver emits an intermittent buzzer.
[0042]
The switches 106 and 108 are supplied with power line power from the visited home via the breaker 118.
[0043]
As described above, since all the facilities necessary for bathing services are installed in a small vehicle, a skilled driver is unnecessary and a female caregiver can drive, so the initial cost and labor cost are significantly reduced.
[0044]
Also, even if you use too much bath water, you will be warned and bath water will be replenished at the place you visited, so caregivers can continue bathing with peace of mind.
[0045]
In addition, when adjusting hot water temperature by mixing hot water and cold water in winter and cold areas, there was a case where the adjustment would be unstable due to the drop in hot water temperature, but the caregiver confirmed the bath temperature with a thermometer However, if this is adjusted manually, bathing service can always be performed at the optimum temperature.
[0046]
Moreover, since there is no mechanical vibration part, it is extremely quiet and does not cause noise in residential areas.
[0047]
Cables and hoses can be easily connected with a single touch even by women, and sufficient consideration is given to handling.
