Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bathroom air conditioner used for drying, ventilating, or heating clothes and a bathroom.
[0002]
[Prior art]
In recent years, there has been an increase in mutual income for couples, and there has been an increasing demand for drying laundry indoors at night. Also, in the cold season such as winter, the interior of the bathroom before bathing in the bathtub is cold, and there is an increasing demand for warming up the bathroom before bathing.
[0003]
Thus, various bathroom air conditioners for drying, ventilating, or heating clothes and the bathroom have been proposed (see, for example, Patent Document 1).
[0004]
Moreover, what incorporates a negative ion generating means and ventilates the air containing a negative ion in a bathroom is also known (for example, refer patent document 2). Negative ions are said to have the effect of stabilizing the mind and enhancing the function of the respiratory organs.
[0005]
On the other hand, the bathroom is a hot and humid space, and even after ventilation after bathing, moisture remains for a while, so mold and tiles and ceiling tend to become unsanitary. For this reason, it is necessary to remove mold by spraying a chlorine-based chemical when cleaning the bathroom, which not only requires time and effort for cleaning, but also makes the patient feel unwell.
[0006]
Therefore, a space sterilization device such as an ozone generator is installed in the bathroom, and mold spores floating in the air are killed to prevent mold from adhering to the tile and ceiling, creating a clean bathroom environment free from mold. The proposal which implement | achieves is made | formed (for example, refer patent documents 3-6).

[Problems to be solved by the invention]
However, since ozone gas is a harmful substance for humans, it is necessary for the ozone generator to operate in a time zone where people do not enter or leave the bathroom. There were many inconvenient points such as being unable to do so.
[0009]
The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a bathroom air conditioner that can suppress the generation of mold by inactivating mold and germs floating in the bathroom. .
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes an air inlet facing the bathroom, an air outlet facing the bathroom, a vent for exhausting the air in the bathroom to the outdoors, and the inlet Circulation passage leading to the outlet, exhaust passage leading from the suction port to the ventilation port, a blower for circulating air in the bathroom or air in the bathroom, and generating positive and negative ions provided in the circulation passage And a heat source that is provided in the circulation passage and that can control energization on / off or increase energization to increase the amount of heat generation and control to reduce energization to reduce the amount of heat generation. The bathroom air conditioner has various operation modes, and in the operation mode, exhausts moisture in the bathroom to the outside and energizes the heat source to circulate hot air in the bathroom. There is a drying mode to let this drying mode After row during or ends, and drives the ion generating device in the weak and with or energization of the heat source stops energization of the heat source.
[0012]
And it has various operation modes, It has the control means which controls generation | occurrence | production and a stop of positive / negative ion or a negative ion according to the said operation mode, It is characterized by the above-mentioned.
[0014]
Alternatively, human body detection means for detecting the presence of a person is provided, and generation of positive and negative ions or negative ions is controlled based on the detection result of the human body detection means.
[0015]
Further, the present invention is characterized in that positive and negative ions are generated by driving the ion generator during or after discharging air in the bathroom.
[0016]
Therefore, the laundry is dried by hanging the laundry such as clothes in the bathroom and executing the drying mode. Moreover, since mold and germs entering from outside the bathroom are inactivated by positive and negative ions, it is possible to prevent mold from being generated in the laundry and bathroom.
[0017]
Furthermore, a timer is provided, and power is saved by energizing the heat source after a predetermined time has elapsed since the start of a predetermined operation mode.
[0018]
Alternatively, a humidity sensor for detecting the humidity in the bathroom is provided, and control is performed to turn off the power to the heat source when the humidity in the bathroom falls below a predetermined reference value during execution of the predetermined operation mode. Also good.
[0019]
Although it is desirable to provide a louver at the air outlet, it is desirable to be able to change the direction of air flow.However, since the louver is located at the air outlet, positive and negative ions sent on the air flow are the first. It can be said that the object is highly likely to collide. Positive and negative ions generated in the air naturally disappear after a lifetime of several seconds, but in addition, they have a property of disappearing when they collide with an object (such as a metal).
[0020]
The louver is used to change the direction of the wind, but depending on its inclination, it may give a large resistance to the air flow. In this case, the collision between the positive and negative ions and the louver is a relatively large area on the louver surface. Therefore, the amount of positive and negative ions due to the collision is severely attenuated. Therefore, it is necessary not to reduce the amount of ions supplied to the bathroom in order to prevent the inactivation of mold and germs floating in the bathroom, but in this case, ions are generated regardless of the angle of the louver. If the amount of positive / negative ions generated from the apparatus and the airflow of the fan are always kept large, unnecessary ion generation power and fan drive power will be lost when the louver has a small air resistance.
[0021]
Therefore, by adjusting the ion generation amount generated from the ion generator and the fan air volume according to the louver angle, a necessary and sufficient amount of positive and negative ions is supplied into the bathroom regardless of the louver angle.
[0022]
The present invention can also be applied to a bathroom air conditioner of the type installed on a bathroom wall. That is, the bathroom air conditioner of the present invention is attached to an opening provided on the side wall of the bathroom for communicating the inside of the bathroom with the outside, and a ventilation unit for exhausting the air in the bathroom to the outside, and the bathroom with respect to the ventilation unit A circulation unit attached to the side for circulating the air in the bathroom, an ion generator provided in the circulation unit for generating positive and negative ions, and on / off control or energization of the energization provided in the circulation unit And a heat source that enables control to increase the calorific value by increasing the amount of heat and control to decrease the calorific value by decreasing the energization, and the ventilation unit and the circulation unit can be operated individually, and the ventilation unit and the Combined with a circulation unit, exhausts moisture in the bathroom to the outside, and has a drying mode in which hot air is circulated in the bathroom by energizing the heat source. The after completion, and drives the ion generating device in the weak and with or energization of the heat source stops energization of the heat source.
[0024]

Depending on the inclination of the louver 10, the flow of air that passes through the air outlet 7 and is blown into the bathroom 11 can be fixed in a predetermined direction or swung in a wide range.
[0026]
Next to the bathtub 12 is a washing place 13, and an inspection port 15 and a lid 16 are provided in a portion of the ceiling board 2 located above the washing place 13. The door 17 is formed with a gallery 18 serving as a ventilation opening. A controller 19 and a switchboard 20 of the bathroom air conditioner 1 are disposed on the outer wall surface of the bathroom 11, and the controller 19 and the switchboard 20 are connected to the bathroom air conditioner 1 through a power line and a control line, respectively. The main body 4 is connected to the exhaust ducts 21 and 22 so that the air in the bathroom 11 sucked by the main body 4 can be exhausted outdoors.
[0027]
FIG. 3 is a schematic cross-sectional view of the bathroom air conditioner 1. An axial flow type fan 24 that rotates in the horizontal direction is provided on the upper left side in the main body 4. The fan 24 is fixed to a shaft of a fan motor 25 provided outside the upper surface of the main body 4. Further, the inside of the main body 4 is divided into a lower left room 28 and an upper and right room 29 by a partition member 27 that also serves as a fan casing. The partition member 27 is formed in a cylindrical shape as an introduction opening 27A where the portion facing the lower surface of the fan 24 faces the room 27, and the portion facing the air outlet 7 of the panel 5 as a discharge opening 27B. The interior of the bathroom 11 and the room 28 communicate with each other through the suction port 6 of the panel 5, the rooms 28 and 29 communicate with each other through the introduction opening 27A, and the air outlet 7 that overlaps the downstream end of the discharge opening 27B. The room 29 communicates with the inside of the bathroom 11. The room 28 is an upstream area of the fan 24, and the room 29 is a downstream area of the fan 24.
[0028]
In the main body 4, a circulation passage extending from the suction port 6 through the rooms 28 and 29 to the outlet 7 and an exhaust passage extending from the suction port 6 through the rooms 28 and 29 to the ventilation port 8 are formed. A damper 9 for switching the air flow of the fan 24 to either one or both is provided at a branch portion between the circulation passage and the exhaust passage.
[0029]
Here, the damper 9 is used to switch between the circulation passage and the exhaust passage, but the present invention is not limited to this. Further, the heat source by the heating means may be a heat exchanger that generates heat by hot water such as the ceramic heater 30. For example, the bathroom air conditioner 1 shown in FIG. 16 includes a ventilation unit 1B that is attached to an opening 55 that allows the inside of the bathroom 11 provided on the side wall 54 of the bathroom 11 to communicate with the outside, and that exhausts the air inside the bathroom 11 to the outside. A circulation unit 1A that is attached to the bathroom 11 side with respect to the ventilation unit 1B and circulates air in the bathroom 11, an ion generator 23 that is provided in the circulation unit 1A and generates positive and negative ions, and the circulation A ceramic heater 30 and an infrared heater 52 provided in the unit 1A are provided, and the ventilation unit 1B and the circulation unit 1A can be individually operated. According to this configuration, heating, ventilation, cool breeze, cool breeze, and ventilation can be performed by using the circulation passage 24 and the ventilation passage as independent air passages and independently operating them using the circulation fan 24 and the ventilation fan 50. . In addition, a configuration is also included in which two fans, a ventilation fan and a circulation fan, are provided in the apparatus main body, and each fan can be driven independently and supplied to an independent ventilation air passage and circulation air passage.
[0030]
A heat source such as a ceramic heater 30 is provided in a circulation passage located on the downstream side of the damper 9 in the room 29, that is, in the introduction opening 27B. An ion generator 23 that generates positive and negative ions is provided further downstream of the ceramic heater 30. The installation position of the ion generator 23 may be upstream of the ceramic heater 30. A humidity sensor 31 is provided on the upstream side of the damper 9 in the room 29.
[0031]
FIG. 6 shows a control block diagram of the bathroom air conditioner 1. A control unit 32 composed of a microcomputer is connected to the switchboard 20 and is supplied with power, and the rotation speed of the fan 24, the position of the damper 9, the inclination and swing of the louvers 10A and 10B, the energization to the ceramic heater 30 and the ion generator 23 To control. Therefore, various operation modes (air conditioning modes) are realized by individually controlling these operations using the controller 19. There are four typical operation modes: heating, ventilation, cool breeze, and drying. In addition, the control unit 32 has a built-in timer 33 for measuring time, and the user can switch between an on timer that turns on at a predetermined time and a turn off timer that turns off the power.
[0032]
FIG. 7 is a plan view of the controller 19. In the upper part of the front surface of the controller 19, a display unit 34 for performing liquid crystal display such as time and operating state is formed. Various buttons are arranged below the display unit 34. That is, the stop button 35 is used as a fan when the operation is stopped, the heating button 36 is used to heat the bathroom 11 in the heating mode, the drying button 37 is used to dry clothes in the drying mode, and the cool air button 38 is used as a fan in the cool air mode. The ventilation button 39 is used to dry the bathroom 11 in the ventilation mode, and the timer button 40 is used to increase or decrease the timer time. Also, in the lower right of the front of the controller 19, a cluster ion lamp 41 that is lit when positive and negative ions are generated from the ion generator 23, and a negative ion that is lit when negative ions are generated from the ion generator 23. An ion generation stoppage lamp 43 that is lit when the driving of the lamp 42 and the ion generator 23 is stopped is arranged vertically. These lamps are composed of LEDs.
[0033]
FIG. 8 is a plan view of the panel 5. The human body sensor 14 is provided in the right corner of the front surface of the panel 5. Along with the front side of the panel 5, a cluster ion lamp 44 that is lit when positive and negative ions are generated from the ion generator 23, and a negative ion that is lit when negative ions are generated from the ion generator 23. A lamp 45 and an ion generation-stopped lamp 46 that is lit when the driving of the ion generator 23 is stopped are arranged side by side. These lamps are composed of LEDs.
[0034]
Instead of the lamp, a liquid crystal display unit 47 that can darkly display a graphic in which “−” and “+” are arranged vertically as shown in FIG. 9 is provided on the controller 19 and the panel 5, and positive and negative ions are supplied from the ion generator 23. Is displayed as shown in FIG. 9A, and when negative ions are generated from the ion generator 23, it is displayed as shown in FIG. 9B, and the ion generator 23 is driven. When it is stopped, it may be displayed as shown in FIG. In particular, in the case of FIG. 9 (A), the display is similar to the Chinese character “dry”, and as will be described later, positive and negative ions are generated in a dry mode for drying clothes, which is a laundry for the user. Intuitive recognition of “drying” is preferable.
[0035]
Next, each operation mode of the bathroom air conditioner 1 will be described with reference to FIGS. The heating mode is an operation mode in which the bathroom 11 is warmed before taking a bath in the cold winter season. When this mode is selected, the control unit 32 opens the ventilation port 8 by the damper 9 as shown in FIG. By closing and driving the fan motor 25, the air flow of the fan 24 is switched to the circulation passage, and the air in the bathroom 11 is circulated as shown by the arrow A. Further, the ceramic heater 30 is energized. The air heated by the ceramic heater 30 is sent into the bathroom 11 and the temperature in the bathroom 11 rises. Thereby, an increase in blood pressure and an uncomfortable feeling due to a rapid temperature change before and after bathing can be prevented. In the heating mode or when the human body sensor 14 detects the presence of a person, the ion generator 23 may be driven to generate negative ions. Thus, based on the detection result of the human body sensor 14, a negative effect is generated in the bathroom 11 by generating negative ions when the presence of a person is detected. When the user leaves the bathroom 11, positive / negative ions are generated again if the mode is one in which positive / negative ions are generated in the drying mode described later based on the air conditioning mode.
[0036]
Further, as shown in FIG. 16, in the case where a far-infrared heater 52 such as a carbon lamp is provided, the radiant heat emitted from the infrared heater 52 is reflected by the reflector 53 into the bathroom 11 to heat the bathroom 11 during bathing. You can also do it. When negative ions are generated from the ion generator 23 during bathing heating, a relaxation effect can be effectively obtained.
[0037]
The ventilation mode is an operation mode in which the bathroom 11 is dried with a strong ventilation function. When this mode is selected, the control unit 32 closes the inlet of the air discharge unit 27A by the damper 9 as shown in FIG. By driving the fan motor 25, the air flow of the fan 24 is switched to the exhaust passage, and the air in the bathroom 11 is exhausted outdoors as indicated by the arrow B. At this time, the ceramic heater 30 is not energized. The humid air in the bathroom 11 is exhausted to the outside, and the interior of the bathroom 11 is dried. Note that the ion generator 23 may be arbitrarily driven. In this case, positive and negative ions are sent into the duct 21 to inactivate mold and germs floating in the duct 21, and mold is generated in the duct 21. It can be prevented from occurring.
[0038]
The cool breeze mode is a mode in which the bathroom air conditioner 1 is used as a fan during bathing in a hot and humid time such as summer. When this mode is selected, the control unit 32 places the damper 9 in an intermediate position as shown in FIG. And the fan motor 25 is driven to switch so that the air flow of the fan 24 flows in both the circulation passage and the exhaust passage, and the air in the bathroom 11 is circulated as indicated by the arrow A, and the arrow Exhaust a part outdoors like B. At this time, the ceramic heater 30 is not energized. Thereby, it blows gently in the bathroom 11, and a bather can cool down. When the human body sensor 14 detects the presence of a person, the ion generator 23 may be driven to generate negative ions.
[0039]
The drying mode is an operation mode in which clothes such as clothes are hung in the bathroom 11 and dried, and when this mode is selected, the control unit 32 controls the fan 24 as shown in FIG. The air flow is switched so as to flow in both the circulation passage and the exhaust passage. Further, the ceramic heater 30 and the ion generator 23 are energized. The air heated by the ceramic heater 30 is sent into the bathroom 11 and the temperature in the bathroom 11 rises. Moisture evaporated from the laundry is exhausted outdoors, and the laundry is dried. In addition, positive and negative ions generated from the ion generator 23 are sent into the bathroom 11 to inactivate mold and germs floating in the bathroom 11, thereby preventing mold from being generated in the bathroom 11 and the laundry. Can do. Thus, the generation | occurrence | production of the mold | fungi in a bathroom can be prevented effectively by discharging | emitting high-humidity air in the bathroom 11, and generating a positive / negative ion, reducing or reducing a humidity.
[0040]
The energization of the ceramic heater 30 can be controlled so that positive and negative ions can be appropriately generated, and warm air and positive and negative ions can be mixed and supplied into the bathroom 11. If the amount of ion generation increases when the temperature in the bathroom 11 is increased, energization to the ceramic heater 30 is increased to increase the amount of heat generation, and if it is better to lower the temperature, It is also possible to reduce the amount of heat generated by weakening energization.
[0041]
Further, the present invention is not limited to the case where the ceramic heater 30 is energized as the drying mode is being executed. If the ion generator 23 is affected by the heat of the ceramic heater 30 on the upstream side of the ceramic heater 30 and hinders the generation of ions, etc., the energization of the ceramic heater 30 is performed automatically during or after the main drying mode. In order to supply positive and negative ions into the bathroom 11, the ion generator 23 is operated, positive and negative ions are generated for a predetermined time, and the fan 24 is rotated to influence the effect of heat when the ceramic heater 30 is energized. Without receiving, a large number of positive and negative ions can be generated for a predetermined time. At that time, if the air is exhausted while part of the air in the bathroom 11 is exhausted, the humidity can be lowered and more effective.
[0042]
The execution of the drying mode means a state from when the drying button 37 is pressed until it is finished. Even in this case, positive and negative ions may be generated during execution of the main drying mode. The energization of the ceramic heater 30 is turned off to generate positive and negative ions, and the bathroom 11 is not affected by heat. It only needs to be able to supply inside.
[0043]
Moreover, when it exists in the position which is not influenced by the ceramic heater 30, it is also possible to control and supply the warm air supplied in the bathroom 11 to appropriate temperature.
[0044]
The term “after drying mode” does not have to be immediately after the drying mode, but may be generated after a predetermined time has elapsed. In addition to the normal drying mode in which sterilization is not performed, the sterilization operation may be performed after drying as a sterilization drying mode. In that case, it will be performed if the disinfection drying button 60 provided in FIG. 7 is selected. In addition, although demonstrated in dry mode, other air-conditioning modes may be sufficient. It goes without saying that the control of heater energization includes not only increasing or decreasing the amount of heat generation but also performing normal on or off.
[0045]
In addition, it is possible to provide a single sterilization mode. When the sterilization button 61 provided in the controller 19 shown in FIG. 7 is selected, the fan 24 is activated and the ion generator 23 is driven. Thus, positive and negative ions are generated and supplied into the bathroom 11. In this case, in order to consider the disappearance of positive and negative ions due to the heat of the ceramic heater 30, the energization to the heat source such as the ceramic heater 30 is not performed. In addition, although a part of the air in the bathroom 11 may be exhausted to reduce the humidity, only the circulating air may be used.
[0046]
The control flow in the drying mode will be described by taking the bathroom air conditioner 1 provided with the louver 10 at the air outlet 7 of FIG. 10 as an example. FIG. 11 is a flowchart illustrating an example of the drying mode. When the drying mode is started, the timer 33 is activated in step # 1, the fan 24 is driven in step # 2, and the ceramic heater 30 and the ion generator 23 are energized in steps # 3 and # 4. In step # 5, the louver 10 is variably controlled so as to swing, and air containing positive and negative ions is blown over a wide area in the bathroom 11.
[0047]
At this time, depending on the inclination of the louver 10, a large resistance may be given to the air flow containing positive and negative ions. In this case, the collision between the positive and negative ions and the louver 10 occurs in a relatively large area on the surface of the louver 10. Therefore, the loss of positive and negative ions due to collision becomes severe. Therefore, in order not to drop the function of inactivating mold and germs floating in the bathroom 11, step # 6 according to the angle (tilt) of the louver 10 so as not to reduce the amount of ions supplied into the bathroom 11. It is necessary to control the amount of positive and negative ions generated and the air volume of the fan 24 at # 7.
[0048]
FIG. 13 shows a schematic diagram when controlling the amount of positive / negative ion generation by classifying the angle of the louver 10 into three types, and FIG. 14 shows a control flowchart thereof. In step # 31, the angle sensor 35 provided in the louver 10 detects the angle θ of the louver 10 and outputs it to the control unit 32. When the angle θ of the louver 10 is 90 ° (see FIG. 13A), the control unit 32 controls the driving of the ion generator 23 so as to reduce the generation amount of positive and negative ions (steps # 32 and #). 33). Further, when the angle θ of the louver 10 is in the range of 45 ° <θ <90 ° and 90 ° <θ <135 ° (see FIG. 13B), ions are generated so that the generation amount of positive and negative ions is moderate. The drive of the generator 23 is controlled (steps # 34 and # 35). Further, when the angle θ of the louver 10 is in the range of θ ≦ 45 ° and 135 ° ≦ θ (see FIG. 13C), the driving of the ion generator 23 is controlled so as to increase the generation amount of positive and negative ions. (Step # 36). FIG. 15 shows a flowchart for controlling the air volume of the fan 24 in the same manner.
[0049]
Then, when it is determined that a certain time has elapsed since the drying mode was started in Step # 8 of FIG. 11, the energization of the ceramic heater 9 is turned off in Step # 9, and the air volume of the fan 24 is minimized in Step # 10. The fan motor 25 is controlled so that the inclination of the louver 10 is fixed in a certain direction in step # 11. Here, the fan motor 25 is controlled so as to minimize the air volume, but the energization of the ceramic heater 30 may be turned off without changing the air volume. Generation of positive and negative ions may be performed from the start of the drying mode, or may be generated after a predetermined time has elapsed.
[0050]
FIG. 12 shows an example in which the drying mode is controlled by the humidity in the bathroom 11. In any case, when the humidity in the bathroom 11 is sufficiently lowered, air containing positive and negative ions is slowly blown into the bathroom 11 to inactivate mold and fungi floating in the bathroom 11 sufficiently. Power saving and low noise.
[0051]
As described above, by controlling the generation or stop of negative ions and positive and negative ions according to various air conditioning modes, a relaxation effect can be obtained from negative ions at the time of bathing, etc., and in the bathroom by positive and negative ions at the time of drying etc. It is possible to obtain a plurality of different effects such as inactivation of mold. In addition, the ion generator may be driven independently to generate negative ions or positive / negative ions without being linked with various air conditioning modes, and the case of being linked with the air conditioning mode and the case of manual selection can be selected. May be. In this case, an ion generation switch may be provided in the main body, and the ion generation apparatus can be operated in the bathroom without operating a remote controller that is usually installed outside the bathroom.
[0052]
In the above embodiment, the case where the ion generator 23 is turned on / off in conjunction with the operation of the bathroom air conditioner 1 has been described. Thus, control to turn on / off can be considered. Alternatively, after the operation of the bathroom air conditioner 1 is stopped, positive and negative ions may be generated in a set time (for example, 1 hour or more) and supplied into the bathroom 11. It is also possible to automatically operate the bathroom air conditioner 1 in a time zone in which the bathroom 11 is used frequently or in a time zone set by the user. In this case, if the operation time and the number of times of the automatic driving are made variable from the date, a great effect can be expected at a time when mold is particularly likely to occur such as rainy season.
[0053]
【The invention's effect】
As described above, according to the bathroom air conditioner of the present invention, positive and negative ions can be supplied into the bathroom during clothes drying operation. Therefore, mold entering from outside the bathroom is inactivated by positive and negative ions during drying of the clothes, so that generation of mold in the bathroom can be effectively prevented. Since these positive and negative ions are harmless to the human body, even if there is a person in the bathroom, it can be generated with peace of mind, and an easy-to-use bathroom air conditioner can be provided.
