Description

  The present invention relates to a toilet room cooling and heating device in which air blowing conditions for locally blowing air to a user can be suitably set.

  Conventionally, when ensuring a comfortable temperature environment [air-conditioning] during use by a cooling / heating device (air-conditioning device) used in a toilet room, a system that mainly cools the entire toilet room, or a user A method of locally sending a cool breeze is adopted. In other words, the former provides a comfortable space by detecting the room temperature and maintaining it at a predetermined set temperature. On the other hand, in order to ensure a comfortable temperature environment during use, Therefore, it is necessary to operate continuously for a considerable period of time so that it can cope with irregular use situations of toilets. From the point of view, there was a problem that energy costs were wasted.

On the other hand, the temperature of the whole toilet room is not controlled for the latter. For example, as disclosed in Japanese Patent Application Laid-Open No. 11-257716, a cool air is directly applied to the user's body to obtain a cool feeling. It is. This is focused on the fact that the user's behavior in the toilet is standing (for boys) or sitting. In this case, since it is operated only when the toilet is used, it is superior in terms of energy cost compared to the method of cooling the entire toilet room, but it is used to ensure a higher level of comfort. It is not only the control that corresponds to each person's standing state and sitting state, but in terms of obtaining a more sophisticated cool feeling by controlling the air temperature, air volume, and wind direction, etc. It was something that left room.
Japanese Patent Laid-Open No. 11-257716

  This invention is invented in view of the said background art, The subject is providing the toilet room air conditioner which can set the ventilation conditions at the time of ventilating locally with respect to a user in detail. That is.

  In order to solve the above-mentioned problem, in the toilet room air conditioner of the invention according to claim 1, the direction of the air-conditioned air blown from the air-blowing port and the air-blowing port in the toilet room is determined. Toilet room air-conditioning / heating device having a rotatable wind direction adjusting louver to be adjusted, a distance measuring sensor is provided in the wind direction adjusting louver, and a toilet user is scanned by the distance measuring sensor along with the rotation of the wind direction adjusting louver The two-dimensional human body detection makes it possible to set the air blowing condition corresponding to the usage pattern of the toilet user.

  The toilet room air conditioner according to a second aspect of the present invention is the toilet room air conditioner according to the first aspect, characterized in that the direction of rotation of the wind direction adjusting louver is the vertical direction.

  The toilet room air conditioner according to claim 3 is the toilet room air conditioner according to claim 1 or 2, wherein the toilet room air conditioner is an animal heat type air conditioner. Is.

  In the toilet room air conditioner according to the present invention, the toilet room is provided with a conditioned air blowing port and a rotatable air direction adjusting louver that adjusts the direction of the conditioned air blown from the blowing port. In the apparatus, the wind direction adjusting louver is provided with a distance measuring sensor, and the toilet user uses the two-dimensional human body detection by scanning the distance measuring sensor accompanying the rotation of the wind direction adjusting louver. Since the corresponding air blowing conditions are configured to be settable, the automatic air direction control enables the air to be blown on the desired body part in a spot manner under the optimum air blowing condition in the body part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the toilet room air conditioner of this invention is not limited only to the following embodiment, Of course, it can add various changes within the range which does not deviate from the summary of this invention. Here, FIG. 1 schematically shows the state of the air conditioning apparatus and the user when using the toilet indoor air conditioning apparatus of the present invention, (a) is a diagram showing the positional relationship when the user is sitting, (B) is a figure which shows the positional relationship when a user stands. On the other hand, FIG. 2 is a figure which illustrates typically the outline of the structure of the toilet room air conditioner of this embodiment.

  That is, as shown in FIG. 1 and FIG. 2, in the toilet room air conditioner A of the present embodiment, air-conditioned air blown from the air-blowing port 2 and air-blowing port 2 in the toilet room 1. It is a toilet room air-conditioning and heating apparatus provided with the wind direction adjustment louver 3 which can be rotated to adjust the direction of the. Further, a distance measuring sensor 4 is provided in the wind direction adjusting louver 3 and the toilet user 5 is detected by two-dimensional human body detection of the toilet user 5 by scanning of the distance measuring sensor 4 as the wind direction adjusting louver 3 rotates. The air blowing conditions corresponding to the usage pattern are settable.

  As a result, by the automatic wind direction control based on the two-dimensional human body detection of the toilet user 5 by the scanning of the distance measuring sensor 4, the optimum air blowing conditions (for example, wind direction, wind speed) on the desired body part are spotted on the desired body part. , Wind noise, etc.). Specifically, for example, according to the case of cooling, the optimal wind at the body part is sent to the body part where the toilet user can easily get a cool feeling (for example, around the face). As a result, cooling can be performed effectively.

  On the other hand, in the toilet room air conditioner A according to the present embodiment, as shown in FIG. 2, the rotation direction of the wind direction adjusting louver 3 is the vertical direction. As a result, not only the positional relationship when the user 5 sits (see FIG. 1 (a)) or stands (see FIG. 1 (b)), but also the height of each toilet user. Physical features can be easily recognized. Specifically, for example, as shown in FIG. 1 described above, when the wind direction adjusting louver 3 (and the distance measuring sensor 4) is arranged above the toilet room 1, a person (toilet user 5) When the toilet is detected to enter the room, the body of the toilet user 5 is scanned in order up and down, the nearest part is set as the head, and a predetermined air volume according to the distance measured in a slightly lower direction. A comfortable wind can be sent to the human body by sending the wind.

  Furthermore, as shown in FIG. 2, the toilet room air conditioner A can be further suitably configured by using a livestock heat air conditioner. That is, by using an animal-heated air-conditioning system, it is possible to obtain cold air immediately during use [cooling] as compared with a conventional heat exchange type, and spot air conditioning in the toilet room 1 can be achieved. It can be made more effective. This is cooling when not in use, discharging heat energy to the heat storage material (which also functions as a cold storage material) of the livestock heat (cold storage) unit 9 by heating means, and charging the livestock (cold storage) unit during use. This is because only the blower fan 8 is operated via 9 to ensure the immediate effect.

  Specifically, as shown in FIG. 2, a heat exchanging unit 7 is provided below the exhaust heat fan 6, a blower fan 8 is provided in front of the heat exchanging unit 7, and a heat storage (cold storage) unit 9 is provided at the front lower side thereof. And it is the internal structure which provides the ventilation port 2 provided with the wind direction adjustment louver 3. FIG. An intake port 10 is also provided behind the heat storage (cold storage) unit 9. In such a heat storage (cold storage) type, cold storage is performed when air conditioning is not performed, and heat is generated at this time. At this time, heat is generated, but the heat generated during the cold storage is discharged outdoors.

  FIG. 3 is a diagram schematically showing the internal functions of the toilet room air conditioner A according to the present embodiment, which is an animal heat type air conditioner. That is, when not in use [cooling], the heat storage material (cold storage material) in the heat storage (cold storage) unit 9 is caused to release heat energy by the accumulator 11 and the compressor 12 as cooling means, thereby performing cold storage ( “Cool storage operation ○” in the figure). The heat generated at this time is dissipated from the radiator 13 (“exhaust heat fan ○” in the figure), and is exhausted outside the toilet room 1 through, for example, the exhaust heat fan 6 in FIG. On the other hand, by using only the blower fan 8 (also referred to as “cold air fan”) via the heat storage (cold storage) unit 9 during operation (“cold air fan ○” in the figure), cold air can be obtained immediately and rising. Cooling is performed with excellent immediate effect and reduced operation noise. This cooling is particularly effective for spot use in the toilet room 1.

  These configurations are not limited to the above-described cooling, but only in heating, or in cases such as switching between cooling and heating, in each case, a heat storage material (cold storage material) is used for each heat exchange cycle. The present invention can also be implemented in an embodiment in which forward inversion or a Peltier element is used and both sides are used.

  Next, operation | movement of the toilet room air conditioner A of this embodiment is demonstrated more concretely. That is, as shown in this embodiment, when the wind direction adjusting louver 3 (and the distance measuring sensor 4) is disposed above the toilet room 1, the wind direction adjusting louver 3 has a lower surface when not in use. It faces and detects the entrance of a person (toilet user 5). When using the air conditioner, the wind direction adjusting louver 3 is fixed so that when it is detected that the toilet user 5 has entered the room in this state, a cool feeling can be obtained in order to confirm the seating state of the toilet user 5 and during preparation for addition. The air blowing operation is continued while changing the wind direction up and down over time. After enough time for the toilet user 5 to prepare, scan the body of the toilet user 5 in order, set the closest part as the head, and correspond to the distance measured in a slightly lower direction A comfortable wind can be applied to the body of the toilet user 5 by sending a predetermined amount of wind (change depending on the environmental temperature of 3 to 8 m / s). Further, by storing the positional relationship of the toilet when there is no person (toilet user 5) in the initial setting and comparing it with that, a more reliable detection result can be obtained. The same effect can be obtained by executing a switch operation or the like when a person (toilet user 5) wants to operate them without automatically detecting entry.

  Further, the toilet room air conditioner A can perform the same detection even during heating, and after performing two-dimensional human body detection of the toilet user 5 by scanning the distance measuring sensor 4, Compared with the data that is not, you can send comfortable warm air toward your feet. In the case of heating, since a warm feeling in a relatively wide range from the foot to the knee is desired, air blowing in the same range is more effective.

  By making the human body detection two-dimensional in this way, the air can be blown locally to the desired body part under the optimum air blowing conditions in the body part, and as a result, spot cooling / heating can be used more comfortably. In addition, the two-dimensional measurement method can be used for individual recognition when there is no person of similar body type (including body height) between families, and more comfortable cooling and heating according to preference can be performed.

  As described above, in the toilet room air conditioner A according to the present embodiment, the air conditioning air blower 2 and the air conditioning air blown from the air blower 2 in the toilet room 1 are rotated. In a toilet indoor air conditioner equipped with a possible wind direction adjusting louver 3, a distance measuring sensor 4 is provided in the wind direction adjusting louver 3, and a toilet user 5 is scanned by scanning the distance measuring sensor 4 as the wind direction adjusting louver 3 rotates. The two-dimensional human body detection makes it possible to set the air blowing condition corresponding to the usage pattern of the toilet user 5, so that the automatic operation based on the two-dimensional human body detection of the toilet user 5 by scanning the distance measuring sensor 4. By controlling the airflow direction, the air can be blown in a spot on a desired body part under the optimum air blowing conditions in the body part.
