DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for a heat pump system capable of supplying a hot water for a bathtub and a hot water supply for a kitchen or the like.

[0002]

2. Description of the Related Art As a conventional example of a heat pump system capable of supplying a hot water in a bathtub and hot water supply in a kitchen or the like, one described in, for example, Japanese Patent Application Laid-Open No. 1-281379 can be mentioned. This heat pump system has a single outdoor unit having a compressor and an outdoor heat exchanger, a hot water bath of a bathtub, a bath unit having a bath heat exchanger used particularly for additional heating, a hot water supply heat exchanger and A hot water supply unit having a hot water storage tank is connected in parallel with each other. A bathroom remote control for setting the amount of hot water and the temperature of the hot water is attached in the bathroom, while a remote controller for setting the hot water temperature and the like is installed in a kitchen or the like outside the bathroom. Further, Japanese Patent Laid-Open No. 1-1
No. 84364), the operation of the heat pump system is controlled using these remote controllers.

[0003] The above-mentioned remote control usually has a microcomputer comprising a CPU, a memory, and the like. When such a microcomputer is used, a clock function can be configured to display the current time on a display element provided on a remote controller. FIG. 4 is a flowchart showing a time display routine in the operation control device of the conventional heat pump system configured to display the current time on each of the hot water remote controller and the bathroom remote controller.

First, on the hot water supply remote controller side, step S31
, It is determined whether or not the time has been set by the user. If it is determined that the time has not been set, the process proceeds to step S34 to measure the time, and the time display is updated every minute. On the other hand, if it is determined in step S31 that the time has been set, the set current time is read into the microcomputer in the next step S32, and the read current time is transmitted to the bathroom remote controller in step S33. Then, the process proceeds to step S34, and based on the read new current time, time measurement and time display are performed in step S32.

The bathroom remote controller determines whether or not the current time has been transmitted from the hot water remote controller in step S41.
To judge. If it is determined that the data has not been transmitted, the process proceeds to step S43 to measure the time, and the time display is updated every minute as in the case of the hot water supply remote controller. On the other hand, when it is determined in step S41 that the data has been transmitted, the transmitted current time is read into the microcomputer in the next step S42, and the time measured in step S43 is determined based on the read new current time. Performs time display.

[0006] In the operation control device of the above-mentioned conventional heat pump system, not only can the current time be confirmed in a kitchen or the like to which a hot water supply remote control is attached, but also a clock or the like is usually not provided. You can check the current time even in a difficult bathroom,
The user comfort could be improved.

[0007]

In the control device of the above-mentioned conventional heat pump system, a clock function is constituted by a microcomputer in a remote controller for hot water supply or a remote controller in a bathroom, and the current time is displayed. At this time, the reference of the timing is the oscillation frequency of an oscillation circuit configured using a crystal oscillator or the like, which is extremely stable.
However, comparing the oscillation frequency of the hot water supply remote control with the oscillation frequency of the bathroom remote control, they are not always the same. Therefore, there is a difference between the time measured by the hot water supply remote control and the time measured by the bathroom remote control, which is about 2 minutes per month as a standard and about 4 minutes per month at the maximum. The current time grasped by the hot water remote control and the current time grasped by the bathroom remote control are made to coincide with each other only when the clock is adjusted by the hot water remote control. Therefore, when the clock is not set for one month, an average display error of about 2 minutes occurs between the two remote controllers, and when this is accumulated for one year, an error of about 24 minutes occurs. And the time display of the hot water supply remote control installed in the kitchen etc. can not be seen from the bathroom which is a closed space,
In addition, since the time display of the bathroom remote control cannot be seen from the kitchen or the like, it is difficult to notice that the time display of the two remote controls is inconsistent. Therefore, the display of the current time provided for improving the use comfort impairs the use comfort. There was a problem that contributed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and an object of the present invention is to prevent time display errors from being accumulated between a hot water supply remote control and a bathroom remote control. An object of the present invention is to provide an operation control device of a heat pump system capable of improving the use comfort.

Have been. And the heat exchanger 2 for hot water supply
3 is provided on the bottom side of a hot water storage tank 31 constituted by a cylindrical closed type tank, a hot water supply pipe 32 is provided at a hot water supply port on an upper end side of the hot water storage tank 31, and a water supply pipe 33 is provided at a water supply port on the bottom side. Are connected respectively. At this time, to perform the hot water supply operation, the first electromagnetic valve 6 is closed and the second electromagnetic valve 25 is opened to operate the compressor 1. Then, the refrigerant is condensed in the hot water supply heat exchanger 23 via the hot water supply gas pipe 22, and heats the hot water in the hot water storage tank 31. Thereafter, the refrigerant evaporates in the outdoor heat exchanger 10 via the hot water supply liquid pipe 24 and the liquid pipe 13, and is returned to the compressor 1 via the first gas pipe 8 and the four-way switching valve 4.

On the other hand, the hot water unit Y has a bath heat exchanger 30, a water forward pipe 36 and a water return pipe 37 for connecting the bath heat exchanger 30 to a bathtub 35. . A circulation pump 38 is interposed in the outgoing water pipe 36, and by operating the circulating pump 38, the hot water in the bathtub 35 is moved in the direction of the path from the outgoing water pipe 36 to the return pipe 37 for water. Circulate through the bath heat exchanger 30.
At this time, the heat of condensation of the condensed refrigerant in the bath heat exchanger 30 is applied to increase the temperature of the bath water.

In the above heat pump system, the hot water supply pipe 3
The remote controller A for hot water supply is attached to a kitchen or the like where the hot water is supplied from 2, while the remote controller B for bathroom is installed in the bathroom where the bathtub 35 is provided. These remote controllers A and B
Is an operation control device of the heat pump system, and is connected to a control device of the entire heat pump system provided in the outdoor unit X by wire. FIG. 3 (a) shows the operation surface of the hot water supply remote control A, and FIG. 3 (b) shows the operation surface of the bathroom remote control B. As shown in FIG. 1A, the hot water supply remote control A also includes a hot water supply control operation unit 42 in addition to the hot water supply control operation unit 41.
It functions as a centralized remote controller that commands the control of the entire heat pump system. The display unit 40 displays the current time in minutes in addition to the set hot water temperature and remaining hot water amount, and the current time can be adjusted by the time setting unit 43. On the other hand, the bathroom remote control B includes a display unit 44 and a hot water control operation unit 45 as shown in FIG. The display unit 44 displays the current time in minutes in addition to the set hot water temperature and hot water amount, as well as the hot water supply remote controller A.

As described above, the current time is displayed on the hot water remote controller A and the bathroom remote controller B. FIG. 1 is a flowchart showing a time display routine at this time. First, the hot water supply remote controller A determines in step S1 whether or not the time has been set by the user. If it is determined that the time has not been set, the process proceeds to step S4 described below. If it is determined that the time has been set, the set current time is changed to the next step S4.
After reading in the microcomputer in step 2 and transmitting the read current time to the bathroom remote controller B in step S3, the process proceeds to step S4.

In step S4, it is determined whether the current time is 0:00. If the current time is 0:00, the data is transmitted to the bathroom remote controller B at 0:00 in the next step S5. Then, in step S6, the time is measured, and the time display on the display unit 40 is updated every minute.
The data transmission in step S5 is performed only when the current time is initialized in steps S1 and S2.

On the other hand, the bathroom remote controller B determines in step S11 whether or not the current time has been transmitted from the hot water controller A. When it is determined that the data transmission has not been performed, the process proceeds to step S13 to measure the time, and similarly to the hot water supply remote controller A, the time display on the display unit 44 is updated every one minute. On the other hand, when it is determined in step S41 that the data has been transmitted, the transmitted current time is read into the microcomputer in the next step S42, and the above-described step S1 is performed based on the read new current time.
At 3, the time is measured and the time is displayed. For example, when the signal indicating that the current time is 0:00 is transmitted from the hot water supply remote control A as described above, the current time of the bathroom remote control B is also set to 0:00, and the clock is restarted from 0 second. An operation such as starting is performed.

In the operation control device of the heat pump system, the remote control A for hot water supply and the remote control B for bathroom use every 24 hours.
The current time is transmitted to the remote controller B, and the bathroom remote controller B corrects the time display based on the transmitted current time. Therefore, the error of the current time display between the hot water supply remote control A and the bathroom remote control B is eliminated every day, and it is possible to prevent a decrease in the use comfort due to the accumulation of the display errors. That is, if the display error (timekeeping error) between the two remote controllers A and B is 2 minutes per month, the day difference is about 4 seconds.
The display times almost always coincide between B.

Since the transmission of the current time (0:00) is performed from the hot water supply remote control A having the clock adjustment function, the time corresponding to the clock adjustment performed by the hot water supply remote control A can also be displayed on the bathroom remote control B. . Moreover, since the hot water remote controller A functions as a centralized remote controller,
An existing communication control routine from the hot water supply remote controller A to the bathroom remote controller B can be used. Therefore, the use comfort can be improved without complicating the configuration.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be implemented with various modifications within the scope of the present invention. In the above description, data transmission from the hot water supply remote control A to the bathroom remote control B is performed at 0:00 every day, but the data transmission time is not limited to 0:00,
It may be performed several times a day, or about once every few days. In the above description, the time data indicating 0:00 is transmitted from the hot water supply remote controller A. However, if the time at which the data is to be transmitted is predetermined, the time data need not necessarily be transmitted, and the clock to the specific time is not required. Only a signal requesting the adjustment may be sent. Further, the time display routine shown in FIG. 1 and the refrigerant circuit of the heat pump system shown in FIG. 2 are merely examples, and the configuration is not limited to those shown in these drawings.

As described above, in the operation control device of the heat pump system according to the first aspect, the display time is set at predetermined time intervals so that the display time of the hot water supply remote controller provided inside and outside the bathroom and the display time of the bathroom remote control coincide. Is corrected, so that the time display error can be prevented from accumulating between the two remote controllers,
This makes it possible to improve the comfort of use.

In the operation control device for a heat pump system according to the second aspect, the clock setting of the remote controller on the transmitting side can be adjusted on the clock of the remote controller on the transmitting side, so that the use comfort can be further improved.

Further, in the operation control device of the heat pump system according to the third aspect, since the current time can be transmitted by using the transmission function of the centralized remote controller, it is possible to improve the use comfort without complicating the configuration and the control.
