BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control device for a heating system suitable for heating a guest room or the like in a hotel.

[0002]

2. Description of the Related Art In general, in a hotel heating system, an appropriate heating temperature (room temperature) is often fixedly set on the hotel (manager) side, but the heating temperature set in this manner is not necessarily a customer. Since it does not match the preference of the (user), it may be too hot or too cold, thereby impairing the comfort of the customer. Therefore, conventionally, a temperature controller is attached to a wall surface in a passenger room so that a customer can manually set an arbitrary heating temperature.

[0003] However, if the customer goes to bed with the set temperature too high, for example, due to the customer being able to set the temperature freely and operating the temperature controller after being drunk, the room becomes hot. This causes a problem that passes by. Further, if the customer turns off the heating due to a tuck-out, a problem such as too cold when the next customer enters the room occurs, which is not preferable for both the customer and the hotel. In particular, in a floor heating system, such a problem is likely to occur because a temperature gap or a temperature rise time is generated between the floor surface temperature and the room temperature.

The present invention has solved such problems in the prior art. In particular, the present invention relates to a temperature control device of a heating system capable of performing comfortable and optimal temperature control for a guest room of a hotel or the like. For the purpose of providing.

In this case, it is desirable that the first setting function unit 2 be configured so that only a specific person can set the temperature, and that the first setting function unit 2 includes a freezing prevention temperature setting function unit 5 that can be set to an arbitrary temperature condition.

[0007]

According to the temperature control device 1 of the present invention, a specific person such as an administrator can set an arbitrary temperature condition by the first setting function unit 2 (and the second setting function unit 3). An unspecified person such as a user can set an arbitrary temperature condition by the second setting function unit 3, and cannot set the temperature condition by the first setting function unit 2.

Therefore, if the specific person sets an appropriate temperature condition in advance by the first setting function unit 2, the control unit 4 performs heating based on the temperature condition of the first setting function unit 2 and continues as it is. On the other hand, when the unspecified person intends to change the temperature condition, the temperature may be manually set to an arbitrary temperature condition by the second setting function unit 3. Heating is performed according to the set temperature. Then, the control unit 4 continues this state for a preset set time, and after the set time has elapsed, returns to the heating by the set temperature of the first setting function unit 2 again. For this reason,
Heating (including stoppage) based on manual setting by an unspecified person does not continue unnecessarily.

[0009] The first setting function unit 2 only detects the room temperature.
Instead of the floor heating system based on the detected floor temperature.
Control the operation. This causes the floor temperature to rise excessively
When the floor temperature is more important than the room temperature,
In order to regulate the rise, the floor heating system was forcibly stopped,
This will avoid the possibility of low-temperature burns, etc.
Becomes possible. Also, a temperature setting means of the first setting function unit 2
( Anti-freezing temperature setting function unit 5 ) can set an arbitrary anti-freezing temperature, so that it can be used not only for anti-freezing but also as a preheating at night in which the set temperature is arbitrarily changed by combining with a timer or the like. You can also.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will now be described in detail with reference to the drawings.

First, an overall configuration of a floor heating system including a temperature control device 1 according to the present invention will be described with reference to FIGS.

Reference numeral 11 denotes a header attached to, for example, a guest room of a hotel.
Built-in. A supply line 14 is connected to one end of the primary unit of the heat exchanger 12 via an on-off valve 13, and a return line 16 is connected to the other end of the primary unit via an on-off valve 15. The supply line 14 and the return line 16 lead out from the header 11 and are connected to a heat medium supply source (not shown). in this case,

That is, one end of the secondary unit is connected to the supply pipe 20 via the on-off valve 18 and the pump 19, and the other end of the secondary unit is connected to the return pipe 23 via the on-off valve 21 and the check valve 22. Connect to The return pipe 23 has a reverse pipe 23r bent at 180 °. Reference numeral 24 denotes an air vent connected to the return pipe 23. Also, the reverse pipe 2
A plurality of hot water pipes 25 laid on the floor F are connected between the 3r and the supply pipe 20. The hot water pipe 25 is a pipe material formed of rubber, metal, synthetic resin, or the like, and is laid on the floor component Fs as shown in FIG. Then, the top is covered with a self-leveling material L, and further,
A floor F is formed by laying a jutan J or the like thereon. In this case, the floor heating circuit 17 contains a secondary heat medium such as water.

Note that, inside the header 11, 26

28 is a replenishment circuit for replenishing the floor heating circuit 17 with a secondary heat medium. The replenishing circuit 28 includes an air vent 29 and a reserve tank 30 having an alarm for water reduction notification (not shown). The reserve tank 30 is provided between the open / close valve 18 and the heat exchanger 12 via the open / close valve 31 and the check valve 32. Connecting.

On the other hand, reference numeral 1 denotes a temperature control device, which includes a control unit 4 having a microcomputer and the like. Also, 3
Reference numeral 4 denotes a room temperature sensor for detecting a room temperature, and reference numeral 35 denotes a floor temperature sensor for detecting a temperature of a floor surface. As shown in FIG. 2, the control unit 4 is built in a casing 36 that can be attached to a wall surface or the like in a room, and thereby forms a temperature controller 33. The front surface of the temperature controller 33 is configured as an operation panel 33p including operation buttons and a display unit. In particular, the operation button 33c on the operation panel 33p allows a user (unspecified person) to set an arbitrary temperature condition, for example, a heating temperature. It functions as the second setting function unit 3.

The temperature control device 1 is provided with a first setting function unit 2 which allows an administrator (specific person) to set arbitrary temperature conditions, for example, a heating temperature. And an anti-freezing temperature setting function unit 5 that can set the anti-freezing temperature. The first setting function unit 2 is configured so that only a specific person can perform a setting operation, and an unspecified person cannot set. Therefore, as shown in FIG. 2, the first setting function unit 2 has a remote control unit 3 having a two-way communication function including an operation button for setting and a temperature display unit.
8 can be arranged, for example, in a centralized control room or the like, or can be configured by disposing operation buttons for setting on the back surface of the casing 36. Further, the operation panel 33 is operated by inputting a code or the like.
It may be configured so that it can be set from p.

On the other hand, the room temperature sensor 34 is mounted inside or outside the casing 36, and the floor temperature sensor 35 is attached to the upper surface of the self-leveling material L, and is connected to the control unit 4 (temperature controller 33) via a cord 35c. .

Next, the overall operation and functions of the floor heating system including the temperature control device 1 according to the present invention will be described with reference to FIGS.

First, the administrator uses the first setting function unit 2 to set an appropriate heating temperature (preferably,
25 ° C.) (FIG. 3, step A). In addition, an upper limit temperature (for example, 50 ° C.) for the floor surface temperature is set. Furthermore, the time for returning to the heating by the heating temperature of the first setting function unit 2 when the heating by the heating temperature of the second setting function unit 3 is performed is set as the setting time. The set time in this case is a concept including both the time interval and the time. As an example, the time interval can be set at 8 hours, and the time can be set at 0:00 am or the like.

Thus, heating is normally performed under the temperature condition of the first setting function section 2 (FIG. 3, step B). That is, if the control unit 4 drives the pump 19 by operating the motor 27, the second heat medium flows and circulates through the floor heating circuit 17. At this time, since the primary heat medium (hot water or the like) heated from the supply line 14 is supplied to the primary unit of the heat exchanger 12, the secondary heat medium flowing to the secondary unit is heated by the heat exchanger 12. The heated secondary heat medium is supplied to the open / close valve 18 → pump 19 → supply pipe 20 → hot water pipe 25 ... → reverse pipe 23r →
Return pipe 23 → check valve 22 → open / close valve 21 → circulates in the secondary unit path of heat exchanger 12, hot water pipe 25
... heats the floor surface F. Then, based on the room temperature data obtained from the room temperature sensor 34, the control unit 4 performs on / off control of the motor 27, and performs feedback control of the room temperature so that the room temperature becomes the set temperature condition.

Although the room temperature is 25 ° C. or less, the floor temperature detected by the floor temperature sensor 35 is 5 ° C.
If the temperature exceeds 0 ° C., the control unit 4 stops the motor 27 and stops heating the floor F. In this way, the floor temperature is controlled prior to the room temperature to prevent an excessive rise in the floor temperature.

If the user (customer) is too hot or too cold with respect to the heating temperature of 25 ° C., the user can change the heating temperature to an arbitrary heating temperature by operating the second setting function unit 3. That is, the user can operate the operation button 33c of the operation panel 33p of the temperature controller 33 to manually set an arbitrary heating temperature (for example, 28 ° C.) (FIG. 3, step C). Thereby, the control unit 4 gives priority to the temperature condition of the second setting function unit 3, performs heating based on this temperature condition, and performs feedback control so that the room temperature becomes 28 ° C. (FIG. 3, step D). ). Then, when a preset time, for example, 8 hours has passed since the setting of the second setting function unit 3 or 0:00 AM, etc., the heating by the temperature condition of the first setting function unit 2 is automatically performed again. After the return, feedback control is performed so that the room temperature becomes 25 ° C. again (FIG. 3, step E,
F).

Therefore, for example, even if the customer goes to bed with the set temperature too high, such as operating the temperature controller after being drunk, the appropriate time set by the hotel is set when the set time is reached. To return to the proper heating temperature, it is possible to eliminate the problem of the room becoming too hot, and to return to the appropriate heating temperature when the set time is reached, even if the customer turns off the heating due to tucking out Therefore, even when the next customer enters the room, the heating temperature is appropriate.

The anti-freezing temperature setting function unit 5 in the first setting function unit 2 can set an arbitrary anti-freezing temperature. Can also be used as arbitrarily variable night preheating.

In addition, the temperature control device 1 includes a display unit for displaying the on / off state of the motor 27 in the temperature controller 33, and also allows the customer to set an allowable range of temperature conditions, that is, the upper limit of the heating temperature. It has a function to set the lower limit.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example , in the above embodiment, the primary heat medium and the secondary heat medium were respectively circulated in independent circuits using the heat exchanger, but without using the heat exchanger and the pump, the primary heat medium in the supply line was directly heated with hot water. In addition to being configured to be able to supply to the pipe side, a three-way switching valve and a bypass circuit are connected to the supply line, thereby switching the three-way switching valve at the time of heating, supplying the primary heat medium to the hot water pipe, and at the time of stopping heating, The three-way switching valve can be switched to supply the primary heat carrier of the supply line to the return line through the bypass circuit. In addition, the configuration, shape, quantity, and the like of the details can be arbitrarily changed without departing from the gist of the present invention.
