Description

  The present invention relates to a warming / humidifying device that does not occupy a space in a living room even if a warming / humidifying device is installed and does not need to be prepared each time it is used.

  Conventionally, as a means of improving comfort due to the temperature of the indoor environment in winter, for example, oil stoves and fan heaters that are installed in the living room, packaged air conditioners that are installed and installed on the walls of the living room, and the ceiling space of the living room Various heating devices such as an air-conditioning system that is concealed and supplies hot air to a room via a blower duct, and a central heating system that is connected to a hot water circulation type heat source device and warms the room by natural convection are used.

  In a room where the above-described heating device is introduced, it is important to adjust the comfort due to the humidity of the indoor environment as a means for further improving the comfort. In the living environment, the humidity generally considered to be comfortable is 40-60% relative humidity, but the heating system raised above only raises the temperature of the living room, even if the comfort due to temperature can be ensured Because the relative humidity is low, comfort due to humidity cannot be ensured. Therefore, a user who wants to ensure comfort due to humidity prepares a humidifier in the living room, and also performs humidification with the humidifier when performing heating. As a humidifier, for example, a method of generating steam by heating water, a method of infiltrating water into a humidifying filter and blowing it with a fan to vaporize, a method of discharging water droplets by vibration by ultrasonic waves, a nozzle, etc. are used. Various methods such as a method of directly spraying water have been proposed, and all of them are generally popular.

  A common feature of the humidifier is that the user brings the humidifier into a living room where the user wants to humidify, supplies tap water to a detachable storage tank, attaches the water to the humidifier, and then operates the humidifier. Thus, the water in the water storage tank is gradually consumed, and the water is replenished when the water in the water storage tank runs out.

  In the case of this method, it is troublesome to prepare a humidifier each time, and there is a problem that the room space is occupied because it is used in the room.

  To cope with the above problems, a box-shaped main body is installed in the space under the floor as a heating and humidifying device, and when humidification is required, a container containing water is separately attached inside the main body, and the humidifying means is installed in the container. It has been proposed that water is supplied to the container with a water supply valve (see, for example, Patent Document 1).

  Hereinafter, the heating and humidifying device will be described with reference to FIG.

  In the box-shaped main body 101 in which the crossflow fan 102, the fan motor 103, and the heat exchanger 104 are integrated, in particular, the inside of the copper tube of the heat exchanger 104 is used as the air passage 105, and the surface of the copper tube is the hot water passage 106. Further, the main body 101 characterized in that the air suction port 107 is arranged outside the hot water flow path 106 is installed in the underfloor space, and the heat exchanged by the heat exchanger 104 exits from the air blowing port 108. . The air vent 108 is connected to a duct laid in the underfloor space, and air is blown from the floor vent of the living room to the room. If necessary, a container that contains water is separately attached in the vicinity of the air outlet 108, and a humidifying means is attached to the inside of the container, and the container is supplied with water by a water supply valve.

  According to this, in the winter, the air heated through the heat exchanger is supplied to the living room, and when humidifying, humidification is automatically performed by attaching a humidifying means and a container containing water near the air outlet 108. It can be carried out.

  If the operation is stopped for a long period of time, the water will remain inside the container, so the user will perform maintenance on the main unit installed in the underfloor space each time and throw away the remaining water in the container. . Also, because of the structure in which the inside of the copper tube of the heat exchanger is an air passage and the surface of the copper tube is a hot water passage, it is not possible to provide a filter that is easy to maintain in the air passage near the heat exchanger, the air resistance is large, and the air volume There are various practical problems such as high output required to secure the vehicle and driving noise increased.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, the main body 1 includes a sirocco fan 3 and a fan motor 4 as blowing means inside a frame 2 that also serves as an air passage, and is connected to a hot water circulation type heat source machine (not shown) as heating means. And a humidifying filter 6 in which humidifying elements are knitted in a lattice shape as humidifying means. As a means for causing the humidifying filter 6 to absorb water, a humidified water pool 7 made of resin (PP) having low cost and chemical resistance is provided inside the main body 1 and connected to a water supply pipe (not shown). By driving a water supply valve 8, which is a pilot-type solenoid valve that is generally used as a water supply means, humidified water that is clean water is poured into the humidified water pool 7, and the humidified water in the humidified water pool 7 is sucked up. The attached humidifying filter 6 sucks up the humidified water.

  A printed circuit board as a control means for controlling driving of the fan motor 4 and the water supply valve 8 is fixed to the outer frame of the frame 2 by, for example, screws.

  A capacitor, a relay, a transformer, a microcomputer, a current fuse, etc. for turning on and off the operation of the actuator (fan motor 4, water supply valve 8, and drain pump 18 described later) are mounted on the printed circuit board. 9 is provided outside the main body 1.

  An operation command to the control unit 9 is given by a wired remote controller 11 provided in the vicinity of the floor heating remote controller of the living room 14 connected to the control unit 9 via the communication line 10, for example.

  When an operation command is issued from the control unit 9, the fan motor 4 is driven to rotate the sirocco fan 3, and the clothes panel 12 provided on one side of the main body 1, for example, the side facing the living room 14, is opened near the floor. The air in the room 14 is sucked from the air suction port 12 a through the mesh-like suction air filter 13 and pushed out toward the heat exchanger 5.

  The heat exchanger 5 is composed of a copper tube and a heat radiating aluminum fin. Hot water of about 60 ° C. passes through the copper tube, and the heat energy of the hot water is transmitted to the heat radiating aluminum fin in contact with the copper tube. is there.

  By blowing air to the heat-dissipating aluminum fins, heat is exchanged between the air in the living room 14 and the hot water supplied from the hot water circulation type heat source device, thereby raising the temperature of the intake air.

  That is, hot water of about 60 ° C. is supplied from the hot water circulation heat source machine to the heat exchanger 5 in the present embodiment.

  The temperature of the air after passing through the heat exchanger 5 is increased by receiving heat energy. By passing this air through the humidifying filter 6, the humidified water absorbed by the humidifying filter 6 is compared with the air at normal temperature. Can be efficiently vaporized into humidified air.

  Since the air passing through the humidifying filter 6 contains vaporized moisture, the humidity is increased, and this humidified air is blown into the living room 14 from, for example, a lattice-shaped air outlet 12b opened in the clothing panel 12, 14 air conditioning is aimed at.

  The heating / humidifying device described in the present embodiment is provided with suction temperature detection means 15 that is a thermistor sensor in the vicinity of the sirocco fan 3, and a suction temperature that is a temperature detected by the suction temperature detection means 15 is determined in advance. When it is above, a heat exchanger control valve (not shown), which is a heat valve as a hot water supply control means provided upstream of the heat exchanger 5 (between the intake air filter 13 and the heat exchanger 5). The driving is stopped, and the hot water supply to the heat exchanger 5 is shut off.

  Thereby, unnecessary heating when the room temperature is high can be prevented. Further, when the suction temperature is lower than a predetermined temperature, the rotational speed of the fan motor 4 is reduced to reduce the air volume (about 20% of the steady rotational speed), and the cold wind feeling near the air outlet 12b is felt. Can be reduced.

  Further, when a water supply temperature detecting means 17 as a thermistor sensor is provided in the water supply pipe 8a upstream of the water supply valve 8, and the water supply temperature is not more than a predetermined value, for example, 2 ° C. or less, it has no relation to the supply of humidified water. For example, control is performed to supply water once every 10 minutes for 30 seconds.

  As a result, when a householder has been absent for a long period of time, such as in a cold winter, it is possible to avoid a situation in which the water supply pipe 8a freezes and bursts, causing a water leak inside the system kitchen.

  Further, the drain pump 18 as the drainage means is driven for 30 seconds after 10 seconds from the start of water supply. The driving time of the water supply valve 8 and the drain pump 18 does not need to be 30 seconds, and it is sufficient that water in the branch pipe branched from the main pipe of the water supply pipe is drained. The optimal thing can be selected and constructed from a plurality of drainage control parameters stored in the control unit 9 in advance. When the supplied water is no longer needed, such as when there is excess water in the humidified water pool 7 when the operation is stopped, the drain pump 18 attached to the humidified water pool 7 is driven for a certain period of time and collected in the humidified water pool 7. Drain the water. Since reliable drainage is required when the drain pump 18 is driven, the drain pump 18 is driven only for a time during which the drainage can be reliably completed even when the humidified water pool 7 is full. For example, if the capacity of the humidified water pool 7 is 500 cc and the drainage amount of the drain pump 18 is 30 cc per second, the drain pump is driven for 30 seconds.

  Further, the bottom surface of the humidified water pool 7 is recessed downward only in the range of 5 mm to 20 mm in the installation portion of the drain pump 18, and a slight gradient is provided toward the recess so that the remaining water flows into the recess. It has a shape.

  The humidified water pool 7 is provided with a full water detection sensor 19 which is a float switch as a first water level detection means.

  The float switch is a level switch that determines whether the float (floating) floating on the water surface is full or not according to the liquid level.

  When the full water detection sensor 19 detects full water, the drive of the water supply valve 8 is stopped.

  Thereafter, the humidified water in the humidified water pool 7 is used by the operation of the main body, and 600 seconds after the full water detection of the full water detection sensor 19 is released, the water supply valve 8 is driven until the full water detection sensor 19 detects full water again. Since humidified water is supplied in a cycle of supplying water, excessive supply of humidified water can be prevented.

  In addition, when the full water detection sensor 19 does not detect full water for 40 seconds even though the water supply valve 8 is driven, there is some trouble, for example, a failure of the water supply valve 8 or a stop cock attached to the water supply pipe. It is determined that the water supply is not being performed due to a reason such as being closed, and a water supply abnormality is displayed on the display unit 16 of the wired remote controller 11 and the operation of the main body is stopped.

  Thereafter, the drain pump 18 is driven for a certain time, and the humidified water accumulated in the humidified water pool 7 is drained.

  This is a measure for preventing the humidified water from remaining in the humidified water pool 7 when the water is supplied from the water supply valve 8 slightly. Of course, the above-mentioned 600 seconds and 40 seconds are examples, and the optimum values differ depending on the capacity of the humidifying water pool 7, the humidifying capacity of the main body, and the amount of water supplied from the water supply valve 8.

  In addition, the second water level detecting means has a sufficiently high water level in the humidified water pool 7 than when the full water detection sensor 19 detects full water, and a height at which the water level is detected before the humidified water pool 7 overflows. As shown, an electrode sensitive overflow detection sensor 20 is attached.

  When water touches the overflow detection sensor 20, the resistance value between the electrodes decreases, the overflow is determined, the overflow abnormality is displayed on the display unit 16 of the wired remote controller 11, and the operation of the main body 1 is stopped.

  Thereafter, the drain pump 18 is driven for a certain time, and the water accumulated in the humidified water pool 7 is drained.

  Normally, drainage is completed by driving the drain pump 18 for a certain period of time, but in order to cope with an abnormal situation such as when the water supply valve 8 continues to be supplied due to an open fixing failure, the drain pump 18 of the present embodiment The amount of drainage per unit time is sufficiently larger than the amount of water supply per unit time of the water supply valve 8.

  For example, if the drainage amount of the drain pump 18 is 30 cc / second, the water supply amount of the water supply valve 8 is selected to be 10 cc / second. As a result, even if the water supply valve 8 continues to be supplied due to an open fixing failure, it is possible to avoid a situation in which water leaks inside the system kitchen by driving the drain pump 18 due to overflow abnormality detection. Furthermore, since the water supply valve 8 and the water supply pipe 8a in the present embodiment are connected inside the frame 2, the water flows into the humidified water pool 7 when the water supply valve 8 fails.

  The warming / humidifying device in the present embodiment has a function capable of interlocking control for operating the main body 1 in conjunction with the operation of another heating terminal attached to the hot water circulation type heat source device.

  For example, the main body 1 is also operated in conjunction with the operation of the floor heating.

  And as a method of performing interlock control between the heating terminal and the hot water circulation type heat source machine, a method called E-CON communication or intelligent communication of the common specification by the hot water circulation type heat source machine / heating terminal manufacturer has been conventionally used. The heating / humidifying device in the present embodiment uses any one of the communication methods to turn on the power of a heating terminal such as floor heating, and at the same time, not only the power of the hot water circulation heat source machine but also the power of the main body 1. It is structured to enter in conjunction.

  When the floor heating is operated, heat radiation from the floor surface to the air in the living room 14 occurs, and the temperature of the living room 14 rises and the relative humidity decreases. However, by operating the main body 1 simultaneously with the floor heating, A decrease in relative humidity can be prevented, and comfort due to humidity can be improved. On a day with high humidity such as a rainy day, the user can operate only the wired remote controller 11 to drive only the floor heating and the hot water circulation heat source.

  Moreover, in this Embodiment, when the power supply of floor heating is turned off, it is set as the structure which the main body 1 can also turn off in conjunction. Of course, only the power supply of the main body 1 is used in order to cope with the case where the temperature of the living room 14 is sufficiently high without operating the hot water circulation heat source machine or the heating terminal, such as humidification demand when cooling with an air conditioner in summer. It is also possible to enter.

  The heating / humidifying device in the present embodiment is fixedly installed inside the system kitchen, for example, inside the drawer below the dishwasher installed in the system kitchen. The pipe connecting the hot water circulation heat source machine and the heat exchanger 5 is connected on the surface opposite to the surface on which the costume panel 12 is attached. Since the system kitchen is connected to the main pipe of the water supply pipe and the main pipe of the drainage pipe, there is little effort to draw a branch pipe of the water supply pipe to install the main body 1 and connection to the main pipe of the drainage pipe Is also easy. Furthermore, in the heating and humidifying device according to the present embodiment, drainage is performed by the drain pump 18, so that the drainage pipe can be easily routed as compared with the case of draining with a natural gradient, and the drainage trap (reverse slope of the drainage pipe) is used. There is little worry about causing poor drainage.

  By setting it as the above structures, even if it installs a heating humidification apparatus, it does not occupy an indoor space and can provide the heating humidification apparatus which does not need to prepare every time it uses it.

  In the embodiment, the float switch is attached as the first water level detection means, but it may be an electrode-type full water detection sensor. When water touches the full water detection sensor, the resistance value between the electrodes decreases to determine that the water is full, and the drive of the water supply valve 8 is stopped. Thereafter, the water in the humidified water pool 7 is used by the operation of the main body, and 600 seconds after the full water detection of the full water detection sensor 19 is released, the water supply valve 8 is driven again until the full water detection sensor 19 detects full water. Supply humidified water in a cycle of Regarding the item of water supply abnormality, the operation may be the same as the operation flow described above.

  The heating / humidifying device according to the present invention does not occupy the space of the living room and enables a heating / humidifying device that does not need to be prepared every time it is used. Useful.
