[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cleaning device for cleaning a local body part, and more particularly to a heating device for the cleaning device.
[0002]
[Prior art]
The human body part cleaning apparatus is as shown in FIG. 5 and is used for cleaning the human body part after a stool or the like. Specifically, as shown in FIG. 5A, the human body local washing device is placed on the toilet, and the user operates the operation unit after the stool or the like, so that it is shown in FIG. 5B. Local cleaning is performed with a local cleaning nozzle.
[0003]
In recent years, products that can be used comfortably not only by local cleaning but also by heating the toilet room have been put on the market. In general, room heating is performed by a heating device 1 incorporated in a human body local cleaning device, and an air inlet 2 of the heating device 1 is used as shown in FIG. Provided on the side surface or back surface (not shown) of the human body local cleaning device, and the exhaust port 3 is provided on the back surface of the human local body cleaning device shown in FIG. Provided.
[0004]
The internal structure of the heating device 1 will be described with reference to FIG. 6. When the heating device 1 operates the heating operation switch 13 to start the heating operation, the fan 4 is operated and the air inlet 2 provided in the outer shell of the fan 4 is operated. Air in the toilet room is aspirated. The sucked air passes through the intake duct 5, is heated by the heating means 6 provided downstream of the fan 4, passes through the exhaust duct 7, and is discharged from the exhaust port 3. Control of the heating operation is provided in the middle of the intake duct 5, and the controller 11 constantly monitors the detected temperature detected by the intake air temperature sensor 8 that detects the temperature of the intake air, and the detected temperature is set by the user. The heating operation is continued until the heating temperature is reached.
[0005]
If the controller 11 cannot properly control the fan 4 and the heating means 6 and the amount of sucked air is reduced, the air temperature rises abnormally and the user burns due to high-temperature exhaust, the floor surface etc. melts, Due to the risk of ignition, the overheating prevention device 10 is installed in the heating means energization circuit 17 of the heating means 6. The over-temperature prevention device 10 is connected in series to the heating means energization circuit 17, and when the atmospheric temperature of the heating means 6 rises to a set temperature or higher, the heating means energization is performed by self-melting without passing through the controller 11. The circuit 17 is disconnected.
[0006]
[Problems to be solved by the invention]
However, in the human body local cleaning device incorporating the heating device 1 as described above, when the intake port 2 provided in the outer shell of the device is closed by the user's clothes and the like during heating operation, There was a problem that the ambient temperature of the means 6 rose, the overtemperature prevention device 10 was cut off, and the operation could not be resumed even after the ambient temperature dropped.
[0007]
In the present invention, in view of the problems as described above, even when the intake port 2 is completely blocked, the controller 11 can safely continue the heating operation without causing the overtemperature prevention device 10 to immediately operate. An object of the present invention is to provide a human body local cleaning device with a built-in heating device 1.
[0008]
[Means for Solving the Problems]
As shown in FIG. 1, the present invention is a human body local cleaning device including a cleaning nozzle for cleaning a human body part and a heating device for heating a toilet room, wherein the heating device includes a fan for sucking air. An air intake duct that introduces air into the fan from an air inlet provided on the outer periphery of the human body local cleaning device, an air heating means provided on the downstream side of the fan, and the heated air to the outside of the human body local cleaning device An exhaust duct that discharges to the outside, an intake air temperature sensor that is provided in the middle of the intake duct and detects the temperature of the intake air, and a controller that controls the heating operation by comparing the detected temperature of the intake air temperature sensor with a set temperature. , one or more second intake duct that branches in the middle of the intake duct is provided, and the human private intakes the air for at least one or more of the second intake duct Characterized in that provided in the purification in the device.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
As the heating means 6 used in the present invention, a nichrome wire heater is preferably used, and a PTC heater or the like is also used. The temperature sensor needs to be provided at least in the intake duct 5 and is also preferably provided in the exhaust duct 7.
[0010]
Further , the total cross-sectional area of the second intake duct 19 is preferably smaller than the cross-sectional area of the intake port 2 , and the position of the second intake duct 19 is preferably downstream of the intake air temperature sensor. These are intended to improve the detection temperature accuracy of the intake air temperature sensor 8 and are achieved by sending more intake air from the intake port 2 that best represents the temperature in the toilet room to the intake air temperature sensor 8. ing. An openable / closable damper is provided at the opening of the intake duct provided at the branch point between the intake duct and the second air supply duct or at the air intake port of the second intake duct in order to increase the accuracy of the detection temperature described above. The intake air amount is increased or decreased by opening and closing the damper. The damper may be driven by electricity or by using a shape memory alloy, and is not limited as long as the suction air amount can be varied.
[0011]
FIG. 2 is a control block diagram in the case where temperature sensors are provided in the intake duct 5 and the exhaust duct 7 respectively, and mode selection means 14 for determining an ON-OFF signal from the heating operation switch 13 and The energization control unit 15 controls the heating device 1 by the room temperature determination unit 12 that determines the temperature in the toilet room from the temperature data from the intake air temperature sensor 8. Specifically, the energization control means 15 urges the fan 4 and the heating means 6 only when the toilet room temperature is lower than the set temperature and the heating operation switch 13 is ON. The abnormal temperature detection means 16 compares the detected temperature of the exhaust temperature sensor 9 provided in the exhaust duct 7 with the internally set heating air temperature, and determines whether the temperature of the heating air is equal to or higher than the heating air temperature. If the set temperature is not satisfied and the controller 11 does not satisfy the set temperature, the controller 11 performs feedback control such as controlling the input power to the heating means 6 or controlling the rotational speed of the fan 4 and cannot be controlled. In such a case, a stop signal is transmitted to the mode selection means 14 to stop the heating operation. When the exhaust duct 7 is not provided with a temperature sensor, it is not necessary to provide the abnormal temperature detection means 16, and thus the manufacturing cost can be kept low. However , if the amount of intake air from the second intake duct is small, There is a possibility that the heating means energization circuit for heating the air is cut by operating the overheat prevention device 10. Therefore, it is necessary that the total step area of the second intake duct is 1/3 or more of the intake port step area.
[0012]
Explaining the operation principle of the heating operation, when the user operates the heating operation switch 13 and the mode selection means 14 enters the “operation” state, the controller 11 causes the room temperature determination means 12 to determine the temperature in the toilet room and the user's temperature. Continuously compare with the set temperature. As a result, if the detected temperature of the intake air temperature sensor 8 does not satisfy the user's set temperature, the energization control means 15 energizes the fan 4 and the heating means 6 to start the heating operation. On the contrary, when the temperature detected by the intake air temperature sensor 8 satisfies the set temperature of the user, the energization control unit 15 does not energize the fan 4 and the heating unit 6. Further, when the heating operation is continued and the set temperature of the user is satisfied, the energization control unit 15 turns off the fan 4 and the heating unit 6.
[0013]
In the present invention, by providing the second intake duct 19, even when the event closed intake port 2, the air to allow blow the heated hand stage 6, the thermal cut-out 10 is disconnected Is preventing.
[0014]
【Example】
The embodiment of the present invention will be described with reference to the drawings. As shown in FIG. The heating means 6 is arranged, and the intake air temperature sensor 8 is arranged on the upstream side. Furthermore, the fan 4 and the opening 1 8 provided in the intake duct 5 wall between the intake air temperature sensor 8, an intake pipe for sucking air in the human private cleaning device to the opening portion 18 (second intake duct 19) Provided. The intake duct 5 communicates with an exhaust duct 7 and an exhaust temperature sensor 9 is disposed in the middle thereof.
[0015]
The heating operation is started by the heating operation switch 13 and controlled by the controller 11. Most of the air used for heating is supplied by the air sucked from the intake port 2, but there is also some sucked air from the intake pipe. Therefore, even if the intake port 2 is blocked by a user's clothes or the like, the overtemperature prevention device 10 is prevented from being cut by the air supplied from the intake pipe. Since the intake pipe sucks air in the human body local cleaning device, there is no worry of being clogged, and the human body local cleaning device itself is not manufactured in an airtight state, so there is no damage due to decompression. When airtightness seems to be somewhat high, the decompression of the human body local cleaning device itself is eliminated by making holes in a plurality of locations of the human body local cleaning device.
[0016]
FIG. 3 shows another embodiment of the present invention, which is the same except that the intake pipe in FIG. 1 is replaced with a damper 20. The opening degree of the damper 20 is controlled by the controller 11 to change the amount of suction air. When the damper 20 is used, it is possible to perform suction only from the intake port 2 during normal operation, and to open and suck the damper 20 only when the intake port 2 is closed.
[0017]
FIG. 4 shows still another embodiment, in which not only air suction but also sewage collected in the human body local cleaning device is provided by providing the intake pipe with an inclination not only above the intake duct 5 but also on the bottom surface. Etc. can be discharged. The intake pipe provided on the bottom surface of the intake duct 5 normally sucks air in the human body local cleaning device. However, when sewage or condensed water accumulates in the intake duct 5, It is possible to discharge through the tube to the outside. Therefore, the inside of the human body local cleaning device can be kept clean.
[0018]
【The invention's effect】
As described above, according to the present invention, by providing one or more second intake duct branching from intake duct, in addition to heating the air to be sucked from the human private washing apparatus outline of the air inlet, the second Heating air can be sucked from the intake duct, and even if the suction port is completely blocked, there is no need to disconnect the overheat prevention device and stop the heating operation. Therefore, the controller can continue the heating operation more safely and can provide an easy-to-use human body local cleaning device.
