Hot water mat and control method of hot water mat {HOT-WATER MAT AND THE CONTROL METHOD THEREOF}

The present invention relates to a hot water mat and a control method of the hot water mat, and more particularly, to a hot water mat and a control method of the hot water mat capable of correcting a set temperature so that the sensory temperature becomes the same even when the hot water mat use environment is different. will be.

In general, a hot water mat refers to a heating mat that performs heating by circulating hot water heated to a set temperature along a hot water pipe built into the mat.

Such a hot water mat adopts the Korean traditional heating method, the Ondol method, and can eliminate the risk of generating electromagnetic waves harmful to the human body and the risk of fire or electric shock caused by the electric heating wire, which is a problem with the existing electric mat composed of electric heating wires. There is an advantage.

Such a hot water mat includes a boiler unit in which a heater is installed to heat water, and a mat unit for heating by circulating hot water heated in the boiler unit.

Korean Patent Registration No. 10-1675740 is disclosed as a prior art related to a control method for controlling such a hot water mat.

According to the prior art described above, a temperature sensor is provided in the hot water return pipe, which is a flow path through which hot water circulating the mat part is returned to the boiler part, and the boiler part heats the heater so that the temperature of the water detected by the temperature sensor reaches a set temperature. Is supposed to be controlled.

In this case, the temperature experienced by the user varies depending on the environment in which the mat part is installed. For example, even if the user sets the temperature to 30°C and the water exchange temperature reaches 30°C, the surface temperature of the mat part changes according to the temperature of the surrounding environment including the floor where the mat part is installed, so that the temperature experienced by the user is different. When the ambient temperature is low, the surface temperature of the mat portion is low, so that the user's perceived temperature is low, and when the ambient temperature is relatively high, the surface temperature of the mat portion is relatively high, so that the user's perceived temperature increases.

This difference in temperature is generated depending on the amount of heat lost from the mat part or the connection part of the mat part, the heat insulation condition, whether the mat part is installed on the heated floor, whether the mat part is installed in the bed mattress, and the like.

When the user's sensory temperature is changed in this way, the user has to set the set temperature differently each time according to the environmental conditions of the mat part, causing inconvenience to the hot water mat user.

Hereinafter, a hot water mat and a control method of the hot water mat according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the hot water mat 1 of the present invention includes a boiler unit 100 that heats and stores water and then supplies it, and a mat where heating is performed using hot water heated by the boiler unit 100 as a heat source. It is configured to include the unit 200.

The hot water supply pipe 101 is a piping structure for circulating and supplying hot water between the boiler unit 100 and the mat unit 200, and provides a flow path through which hot water heated in the boiler unit 100 is supplied to the mat unit 200. ), and a hot water return pipe 102 that provides a flow path through which the hot water circulating through the mat part 200 is returned to the boiler part 100 side.

A circulation pump 120 is provided in the pipe line of the hot water supply pipe 101 to provide a pressure feeding force so that water is circulated between the boiler unit 100 and the mat unit 200. The hot water return pipe 102 is provided with a valve 130 for opening and closing the pipeline of the hot water return pipe 102, and a return temperature sensor 140 for detecting the temperature of water returned through the hot water return pipe 102. .

The boiler unit 100 is provided with a water heating unit 110 equipped with a heater 111. In addition, the boiler unit 100 controls the heating operation of the heater 111 and the operation of the circulation pump 120 so that the temperature of water detected by the water exchange temperature sensor 140 reaches the set temperature of the mat unit 200. A control unit 150 is provided.

The control unit 150 determines the installation environment of the mat part 200 from the temperature information of the water heated by the heater 111, and the set temperature of the hot water mat 1 from the determined installation environment of the mat part 200 And a set temperature correction unit 151 for correcting, a heater driving unit 152 for operating the heater 111 according to the corrected set temperature, and a pump driving unit 153 for driving the circulation pump 120. .

When the user uses the hot water mat 1 When the ambient temperature such as the floor on which the mat part 200 is installed is low, the surface temperature of the mat part 200 is low, so the temperature experienced by the user through the mat part 200 is low. Will be lowered. In addition, when the ambient temperature such as the floor on which the mat part 200 is installed is high, the surface temperature of the mat part 200 is relatively high, so that the temperature experienced by the user through the mat part 200 increases. In the present invention, the set temperature correction unit 151 determines the installation environment of the mat unit 200, and corrects the set temperature of the hot water mat 1, so that a deviation in the temperature experienced by the user through the mat unit 200 is It can be prevented from occurring.

In this case, the installation environment of the mat part 200 may be determined from a mat part temperature sensor measuring the temperature (internal temperature or surface temperature) of the mat part 200 itself. In addition, a temperature sensor may be provided at a connection portion to which a pipe is connected to the mat unit 200, and the installation environment of the mat unit 200 may be determined by measuring the temperature at the bottom of the connection unit.

In addition, the installation environment of the mat part 200 can be determined from the temperature of the water. That is, the surface temperature of the mat part 200 may be a temperature similar to the temperature of water flowing through the pipe inside the mat part 200, and the installation environment of the mat part 200 may be indirectly determined from the temperature of the water. . In this way, when determining the installation environment of the mat part 200 from the temperature of the water, it is possible to use a water exchange temperature sensor that has been previously installed, so there is no need to provide a separate sensor.

In the case of measuring the temperature of the mat part 200 or measuring the temperature of water in order to determine the installation environment of the mat part 200 as described above, it is preferable that the heater 111 is not operated. When the heater 111 is operated, the temperature of the water and the temperature of the mat part 200 increase, so that the temperature of the floor where the mat part 200 is installed cannot be accurately determined. Of course, since heated water may not be supplied to the mat unit 200 at the initial stage of operation of the heater 111, the installation environment of the mat unit 200 may be determined at the initial stage of operation of the heater 111.

In addition, in order to determine the installation environment of the mat part 200, only the circulation pump 120 is operated while the heater 111 is not operated to determine the installation environment of the mat part 200 from the temperature of the circulating water. have. Since the temperature sensor for measuring the temperature of water is provided inside the boiler unit 100, the temperature of the water inside the pipe in the mat unit 100 cannot be accurately measured. Therefore, when the circulation pump 120 is operated to circulate water, the water inside the mat part 200 flows to the boiler part 100 with a temperature sensor, so that the temperature of the mat part 200 can be more accurately determined. .

A timer 160 may be provided for measuring a time taken for the temperature of water heated by the heater 111 to reach a target temperature. The time measured by the timer 160 is received by the controller 150.

The target temperature may be a temperature preset in the hot water mat 1. In addition, when the heater 111 is circulated by the circulation pump 120 while the heater 111 is not operated, the target temperature may be set to be a value obtained by adding a predetermined target temperature difference to the temperature of the circulating water. The target temperature may be a temperature lower than the set temperature set by the user for heating.

The target temperature may be configured by adding a target temperature difference to the current water temperature. For example, if the target temperature difference is 5°C and the current water temperature measured by the temperature sensor is 15°C, the target temperature is 20°C. The time information measured by the timer 160 is received by the set temperature correction unit 151.

In addition, the timer 160 may be configured to measure a time taken for the temperature of water heated by the heater 111 to reach a set temperature set by the user. The time measured by the timer 160 is received by the controller 150.

The set temperature correction unit 151 may be set so that the long and short time measured by the timer 160 becomes a criterion for determining the installation environment of the mat part 200. For example, if the floor on which the mat part 200 is installed is in a cold state, the time it takes for the temperature of the water heated by the heater 111 to reach the target temperature or the set temperature will be longer, and the mat part 200 The higher the temperature of the installed floor, the shorter it takes for the water temperature to reach the target temperature or the set temperature.

In the set temperature correction unit 152, a plurality of temperature correction trend lines corresponding to the installation environment of the mat unit 200 may be set. The temperature correction trend line may be made of data on a correction temperature corresponding to the current water temperature according to various installation environments. The set temperature correction unit 151 may select any one of the temperature correction trend lines from the temperature information of the water.

A function setting unit (not shown) and a display unit (not shown) are provided above the case of the boiler unit 100. The function setting unit includes a configuration for the user to set the heating temperature or heating time of water. The display unit functions to display a state of use of the hot water mat, such as a current hot water temperature and a set time.

2 shows a temperature correction trend line according to an embodiment of the present invention.

In FIG. 2, the horizontal axis represents the actual water temperature, and the vertical axis represents the mat part correction temperature. In the graph shown in type 1, when the bottom is full, the temperature correction trend line appears remarkably smoothly, and in the graph shown in type 5, the temperature correction trend line appears sharply because the bottom temperature is relatively high.

Ground condition Floor temperature Time to reach target temperature Time to reach set temperature Temperature correction trend line Cold floor lowness long long Remarkably gentle Ondol floor middle long middle Somewhat gentle Mattress 1 middle short middle precipitation Mattress 2 middle short long Somewhat abrupt

Table 1 shows factors for selecting the temperature correction trend line. The lower the floor temperature in which the mat part 200 is installed, the greater the heat loss in the mat part 200 is, and thus the perceived temperature in the mat part 200 decreases.

The time to reach the target temperature is a factor for determining how much heat loss is through the floor according to the state of the floor at the beginning of operation of the hot water mat 1, and it means that the longer the time to reach the target temperature is, the greater the heat loss through the floor.

The time to reach the set temperature is the total time required to reach the temperature set by the user, and it is determined that all of these factors are reflected because the sensory temperature of the mat part 200 is affected not only by the floor condition but also by the temperature of the indoor air. It is a factor to do.

A method of controlling a hot water mat according to the present invention will be described with reference to FIG. 3.

In step S11, the operation signal of the hot water mat 1 is received by the control unit 150. The activation signal of the hot water mat 1 may be generated by the user pressing the power button.

When the hot water mat 1 is operated in step S12, the pump driving unit 153 operates the circulation pump 120. This step is a step for measuring the floor temperature, and does not directly measure the floor temperature, but indirectly measures the floor temperature by measuring the temperature of water in a state in which the heater 111 is not operated. To this end, the heater 111 is not operated, and only the circulation pump 120 is operated to circulate water in the pipe.

In step S13, it is determined whether the set time has elapsed after the circulation pump 120 is operated. Since the water exchange temperature sensor 140 is provided in the boiler unit 100, in order to measure the temperature of the water in the mat part 200 reflecting the floor temperature, it is necessary to circulate the water in the mat part 200 to the water exchange temperature sensor 140. need. The set time may be appropriately set as a time for sufficient circulation of water.

In step S14, the water exchange temperature sensor 140 measures the water exchange temperature. It is most preferable to directly measure the floor temperature, but it is easy to indirectly measure the floor temperature by measuring the water exchange temperature in the water exchange temperature sensor 140. Of course, this step may be modified by directly measuring the floor temperature on which the mat part 200 is installed, or directly measuring the temperature of the mat part 200. If the temperature or the floor temperature of the mat part 200 is directly measured, it may be configured to perform S11 immediately after performing S11 without performing the steps S12 and S13. The measured return temperature is received by the set temperature correction unit 151.

In step S15, the heater 111 is operated to heat water. In this case, when the circulation pump 120 is in a stopped state, the circulation pump 120 is also operated to circulate water.

In step S16, the temperature of the water heated by the heater 111 is measured by the water exchange temperature sensor 140 to determine whether or not the target temperature has been reached. If the determination result reaches the target temperature, the process proceeds to step S17, otherwise, the hot water mat 1 is maintained in an operating state.

In step S17, the reaching time of the target temperature is measured, and the measured time information is received by the set temperature correction unit 151.

Even after reaching the target temperature in step S18, the operation of the hot water mat 1 continues, and it is determined whether or not the set temperature set by the user has been reached. If the determination result reaches the set temperature, the process proceeds to step S19, otherwise, the hot water mat 1 is maintained in an operating state.

In step S19, the total temperature change time required to reach the set temperature is measured and calculated. The calculated time information is received by the set temperature correction unit 151.

In step S20, the set temperature correction unit 151 selects a temperature correction trend line suitable for the installation environment of the current mat part from among the plurality of temperature correction trend lines, and uses the selected temperature correction trend line to correspond to the installation environment of the current mat part. Correct the set temperature.

In this case, the set temperature correction unit 151 determines any one of a plurality of temperature correction trend lines in consideration of the return temperature measured in step S14, the arrival time of the target temperature measured in step S17, and the arrival time of the set temperature measured in step S19. Choose. In this case, both of the target temperature arrival time and the set temperature arrival time may be considered, but only one of the two may be considered to determine the temperature correction trend line.

In step S21, the hot water mat 1 is operated according to the corrected set temperature.

A method of calibrating the set temperature will be described with reference to FIG. 2, but will be described on the assumption that type 1 is selected in step S20. For example, if the set temperature set by the user is 20°C, the heater 111 is operated until the temperature of water measured by the water exchange temperature sensor 140 reaches 20°C. In this case, the temperature of the water is 20°C, but the temperature of the mat part 200 varies depending on the state of the floor on which the mat part 200 is installed. In the case of type 1, the temperature of the mat part 200 is 10°C. Therefore, in order for the mat part 200 to reach a set temperature of 20°C in a type 1 environmental condition, the set temperature correction unit 151 corrects the set temperature to 28°C. When the set temperature is corrected to 28°C, the heater 111 and the circulation pump 120 are continuously operated until the water return temperature reaches 28°C.

When the hot water mat 1 is controlled in the above manner, the temperature deviation of the mat part 200 experienced by the user is minimized, so that the user can feel a sufficient heating effect.

As described above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above-described embodiments, and various modifications within the scope of the claims, the detailed description of the invention, and the accompanying drawings. It is possible to do so, and this also belongs to the present invention.
