A water purifier according to an embodiment of the present invention will be described with reference to fig. 1 to 22, and the water purifier according to the embodiment of the present invention may be a household type water purifier, for example, a kitchen type water purifier.

As shown in fig. 1 to 6, a water purifier according to a first embodiment of the present invention includes: a filtration system 100, a heating system 200, and a water pump 510.

The filter system 100 has a raw water inlet 101 and a purified water outlet 105, and the raw water inlet 101 may be directly or indirectly connected to a raw water pipe, for example, the raw water pipe may be a tap water pipe. Raw water to be filtered flows into the filtering system 100 from the raw water inlet 101, and purified water flows out from the purified water outlet 105 after being filtered.

The heating system 200 has a water inlet 221 and a water outlet 222, the water inlet 221 of the heating system 200 being connected to the purified water outlet 105 of the filtration system 100, and the water outlet 222 of the heating system 200 being connected to the first water supply inlet of the water purifier. The heating system 200 is used to heat water flowing through the heating system 200.

The water pump 510 is connected to the filtration system 100, and the water pump 510 is disposed upstream of the purified water outlet 105 of the filtration system 100, the water pump 510 is for driving water to flow from the raw water inlet 101 of the filtration system 100 to the purified water outlet 105 of the filtration system 100, and the water pump 510 is for driving water to be discharged from the water outlet 222 of the heating system 200.

In other words, in one operation mode of the water purifier, raw water flows into the filter system 100 from the raw water inlet 101 of the filter system 100, and purified water flows out of the purified water outlet 105 of the filter system 100 after being filtered by the water pump 510, and the purified water flows out of the purified water outlet 105 of the filter system 100 flows into the heating system 200 from the water inlet 221 of the heating system 200, and then flows into the first water supply port of the water purifier from the water outlet 222 of the heating system 200 by the water pump 510 after being heated, thereby supplying hot water.

As shown in fig. 1, the lower portion of the heating system 200 is provided with a water inlet 221, and the upper portion of the heating system 200 is provided with a water outlet 222. In other words, the filtered pure water flows into the heating system 200 from the lower portion of the heating system 200 to be heated, and when the hot water is required, the hot water flows out from the water outlet 222 at the upper portion of the heating system 200 by the water pump 510.

It will be appreciated that the purified water entering the heating system 200, when heated, has a relatively low density of hot water, floats upwards, and a relatively high density of cold water, sinks downwards.

The water pump 510 may drive the raw water to flow from the raw water inlet 601 to the purified water outlet 105 for filtration, and may also drive the hot water to be discharged from the water outlet 222 of the heating system 200.

In other words, the water pump 510 is a driving pump of the filtering system 100 and a driving pump of the heating system 200, and the hot water according to the embodiment of the present invention is not drawn from the heating system 200 by designing a separate suction pump, but is pushed out to the first water supply port of the water purifier by the water pump 510 shared with the filtering system 100 by forming a water pressure difference between the water inlet 221 and the water outlet 222 of the heating system 200, so that external air is prevented from being introduced into the water path of the water purifier, thereby preventing secondary pollution.

As shown in fig. 1, the return pipe 540 is connected between the purified water outlet 105 and an inlet of the water pump 510. When the water purifier is just started, the water pump 510 is operated, purified water from the purified water outlet 105 may be re-sucked into the water pump 510 through the water return pipe 540, and since the water pump 510 is disposed at the upstream of the purified water outlet 105 of the filtering system 100, the sucked purified water may be re-introduced into the filtering system 100 to be at least one-stage filtered.

In other words, when the return pipe 540 is communicated, the outflow of the first cup of water having insufficient quality can be prevented, and the quality of the water introduced into the filtering system 100 is enhanced, so that the quality of the purified water outlet 105 of the filtering system 100 is higher. Especially, for the first cup of water, the quality of the first cup of water can be greatly improved by arranging the water return pipe 540.

According to the water purifier disclosed by the embodiment of the invention, the functions of water purification and heating are integrated, the water inlet 221 is arranged at the lower part of the heating system 200, the water outlet 222 is arranged at the upper part of the heating system 200, and the pushing type water outlet mode of the water pump 510 is combined, so that the external air can be prevented from being introduced into a water channel of the water purifier, secondary pollution is prevented, and the quality of the first cup of water can be greatly improved by arranging the water return pipe 540.

In some embodiments, as shown in fig. 1, the return pipe 540 is provided with a return water control valve 564 for controlling a conduction state of the return pipe 540, the return water control valve 564 may be a solenoid valve, and the return water control valve 564 may be electrically connected to a controller of a water purifier configured to open the return water control valve 564 for a preset time, which may be 5s-25s, such as 10s, each time the water purifier is turned on.

In some embodiments, as shown in FIG. 1, the return pipe 540 is provided with a return check valve 563 and a return control valve 564, and the return check valve 563 is in one-way communication from the purified water outlet 105 to the inlet of the water pump 510. The return control valve 564 is used to control the conductive state of the return pipe 540, the return control valve 564 may be a solenoid valve, and the return check valve 563 may prevent water that is not completely filtered from directly flowing into the purified water outlet 105 or the first water supply port through the return pipe 540.

The water purifier has a fresh water return mode in which the water pump 510 and the return water control valve 564 are turned on. The water purifier is configured to start the fresh water return mode each time the water purifier is powered on, and the fresh water return mode lasts for a preset time, which may be 5s-25s, such as 10 s.

In some embodiments, as shown in fig. 1, the heating system 200 has an exhaust port 223, and the water purifier further comprises: a safety branch 550, the safety branch 550 being connected between the exhaust port 223 of the heating system 200 and the wastewater outlet 602 of the water purifier.

The safety branch 550 is used for releasing pressure through the air outlet 223 and the safety branch 550 when the pressure in the heating system 200 is too high, and the steam or water discharged during the pressure release can be discharged through the waste water outlet 602 of the water purifier.

As shown in fig. 1, the safety branch 550 may be provided with an exhaust check valve 565 and an exhaust valve 566, the exhaust check valve 565 conducting in one direction from the exhaust port 223 to the waste water outlet 602 of the heating system 200. The exhaust valve 566 is used to control the on state of the safety branch 550, the exhaust valve 566 may be a solenoid valve, and the exhaust valve 566 may be electrically connected with the controller of the water purifier, or the exhaust valve 566 may be a pressure valve, and the exhaust check valve 565 may prevent the waste water from flowing backward into the heating system 200.

When the hot water is needed, the exhaust valve 566 is closed, and the heating system 200 is in a sealed state, so that the hot water can be pushed out from the water outlet 222 from bottom to top by the water pressure of the water pump 510.

When the air is exhausted and the pressure is released or the old water is required to be discharged, the air outlet valve 566 is opened, and the hot water can be pushed out from the water outlet from the bottom to the top by the water pressure of the water pump 510.

As shown in fig. 1 to 6, a water purifier according to a second embodiment of the present invention includes: a filtration system 100, a heating system 200, and a water pump 510.

The heating system 200 has a water inlet 221, a water outlet 222 and an air outlet 223, the water inlet 221 of the heating system 200 being connected to the purified water outlet 105 of the filtration system 100, and the water outlet 222 of the heating system 200 being connected to the first water supply inlet of the water purifier.

An exhaust valve 566 is coupled to the exhaust port 223 of the heating system 200.

When the hot water is needed, the exhaust valve 566 is closed, and the heating system 200 is in a sealed state, so that the hot water can be pushed out from the water outlet 222 from bottom to top by the water pressure of the water pump 510. The vent valve 566 may prevent outside air from entering the heating system 200 and causing secondary pollution.

The exhaust port 223 of the heating system 200 is disposed higher than the water outlet port 222 of the heating system 200.

Therefore, the pressure at the exhaust port 223 is smaller than that at the water outlet 222, the exhaust valve 566 can be prevented from being opened by mistake, steam is gathered at the top of the heating system 200, the water outlet 222 is arranged at a position lower than the exhaust port 223, the steam can be prevented from being exhausted from the water outlet 222 and sputtering a user, and the exhaust port 223 is arranged at the top end to facilitate exhaust.

According to the water purifier of the embodiment of the invention, the functions of water purification and heating are integrated, the water inlet 221 is arranged at the lower part of the heating system 200, the water outlet 222 is arranged at the upper part of the heating system 200, and the air outlet 223 with the drain valve is arranged at a higher position, so that the closed heating system 200 can be formed, and the push type water outlet mode of the water pump 510 is combined, so that the external air can be prevented from being introduced into the water channel of the water purifier, and secondary pollution can be prevented.

In some embodiments, as shown in fig. 1, the water purifier according to the embodiment of the present invention may include an exhaust check valve 565, the exhaust check valve 565 may be communicated in a single direction from the exhaust port 223 of the heating system 200 to the waste water outlet 602 of the water purifier, and the exhaust check valve 565 may prevent waste water from flowing backward into the heating system 200.

An exhaust check valve 565 may be disposed between the exhaust valve 566 and the exhaust port 223, or the exhaust valve 566 may be disposed between the exhaust check valve 565 and the exhaust port 223.

In some embodiments, as shown in fig. 1, the water purifier may further include: a water return pipe 540, the water return pipe 540 being connected between the purified water outlet 105 and the inlet of the water pump 510.

When the water purifier is just started, the water pump 510 is operated, purified water from the purified water outlet 105 may be re-sucked into the water pump 510 through the water return pipe 540, and since the water pump 510 is disposed at the upstream of the purified water outlet 105 of the filtering system 100, the sucked purified water may be re-introduced into the filtering system 100 to be at least one-stage filtered.

In some embodiments, as shown in fig. 1, the water return pipe 540 is connected to a position near the second water supply port of the water purifier. For example, in the outlet waterway plate 900 shown in fig. 17, the second port 921d of the first water tube 921 is disposed at a position close to the first outlet 921b of the first water tube 921. Thus, in the fresh water return mode, purified water remaining in the pipeline may be pumped to the inlet of the water pump 510 as much as possible.

As shown in fig. 1 to 12, a water purifier according to a third embodiment of the present invention includes: a first support 310, a filtration system 100, a second support 320, and a heating system 200.

The filter system 100 is mounted to the first bracket 310, the first bracket 310 defines a mounting space for mounting the filter system 100, and the first bracket 310 provides a support skeleton of the filter system 100.

The heating system 200 is mounted to the second bracket 320, the second bracket 320 defines a mounting space for mounting the heating system 200, and the second bracket 320 provides a support skeleton of the heating system 200.

The heating system 200 has a water inlet 221 and a water outlet 222, the water inlet 221 of the heating system 200 being connected to the purified water outlet 105 of the filtration system 100, and the water outlet 222 of the heating system 200 being connected to the first water supply inlet of the water purifier.

The second bracket 320 is detachably coupled to the first bracket 310. For example, the second bracket 320 and the first bracket 310 may be connected by a screw connector, a snap structure, a magnetic structure, etc.

Thus, the water purifier has a simple structural design, and can realize that a plurality of different types of water purifiers share the first bracket 310 and the filtering system 100, for example, for different types of water purifiers, only the second bracket 320 and the corresponding heating system 200 can be redesigned; it is even possible to implement a plurality of different types of water purifiers to share the first bracket 310, the filter system 100, and the second bracket 320, such as only the corresponding heating system 200 may be redesigned for the different types of water purifiers.

In the related art, when designing the multifunctional water purifier, the overall bracket needs to be redesigned for each type of multifunctional water purifier, for example, for the water purifier with the heating function and the water purifier with the tea brewing function, the structures need to be rearranged, and the brackets are designed respectively, so that the development cycle of two sets of product lines is long, and the investment cost of the mold is high.

Due to the water purifier of the embodiment of the invention, the respective supports are independently designed for the filtering system 100 and the heating system 200, so that when facing different types of water purifiers, the related design of the filtering system 100 can be retained to the greatest extent, and the sharing of modules is realized.

According to the water purifier provided by the embodiment of the invention, the detachable and connected bracket is independently designed for the filtering system 100 and the heating system 200, so that the development cost can be reduced, and the development period can be shortened.

The second bracket 320 is detachably coupled to the first bracket 310.

That is, in the water purifier according to the embodiment of the present invention, the respective supports are separately designed for the filtering system 100 and the heating system 200, so that when facing water purifiers of different heating models, the design related to the filtering system 100 can be retained to the greatest extent, the modules can be shared, the development cost can be reduced, and the development period can be shortened.

The following continues to describe the heating module of an embodiment of the present invention.

In some embodiments, as shown in fig. 11, the open end of the second bracket 320 is provided with a first plate 325 and a second plate 326 protruding therefrom, the water guard plate 420 is positioned on the inner side of the first plate 325, the second plate 326 is positioned on the outer side of the first plate 325, and the first plate 325 and the second plate 326 define a raceway 327 therebetween, and the cover plate 410 covers the raceway 327.

It will be appreciated that the first plate 325 is adapted to cooperate with the water deflector 420, the second plate 326 is located outside the first plate 325, the second plate 326 is spaced from the first plate 325 to form a raceway 327 between the second plate 326 and the first plate 325, and that cables exiting the heating system 200 can be routed along the raceway 327 after exiting the mounting cavity 323, and the cover plate 410 extends outwardly relative to the water deflector 420 to cover the raceway 327, so that the heating module is neater in construction.

As shown in fig. 1, 13 to 16, a water purifier according to a sixth embodiment of the present invention includes: a filtration system 100 and a heating system 200.

A heating system 200 according to an embodiment of the present invention is described below with reference to fig. 13 to 16.

As shown in fig. 14, a heating system 200 of an embodiment of the present invention includes: a can 210 and a heat pipe 230.

The heating pipe 230 is installed in the tank 210, and the heating pipe 230 may be an electric heating type, and when the heating pipe 230 is powered on, water in the tank 210 may be heated.

As shown in fig. 15, the bottom 211 of the can 210 faces downward when the heating system 200 is placed in a vertical position, and as shown in fig. 16, the first side 212 of the can 210 faces downward when the heating system 200 is placed in a horizontal position.

The tank 210 has a water inlet 221 and a water outlet 222, the distance from the water outlet 222 to the bottom surface 211 is greater than the distance from the water inlet 221 to the bottom surface 211, and the distance from the water outlet 222 to the first side surface 212 is greater than the distance from the water inlet 221 to the first side surface 212. The first side surface 212 is adjacent to the bottom surface 211.

Thus, when the water outlet 222 is placed vertically, the water inlet 221 is positioned above the water outlet 222, and when the water outlet is placed horizontally, the water inlet 221 is still positioned above the water outlet 222.

It will be appreciated that the water entering the heating system 200 is heated such that the hot water has a relatively low density, floats upwards, and the cold water has a relatively high density, sinks downwards.

In other words, the heating system 200 of the embodiment of the present invention can ensure a sufficiently high temperature of the outlet water regardless of the vertical placement or the horizontal placement. Thus, the heating system 200 can be placed in a proper direction according to a specific installation environment, and the application range is wider.

According to the heating system 200 provided by the embodiment of the invention, the distances from the water inlet and the water outlet to the bottom surface 211 and the first side surface 212 are designed, so that the heating system 200 can ensure the outlet water temperature no matter the heating system is placed vertically or horizontally, and the application range is wider.

Fig. 2 is a schematic structural view of a water purifier according to an embodiment of the present invention, which is placed vertically, and fig. 3 is a schematic structural view of a water purifier according to an embodiment of the present invention, which is placed horizontally, and which can be installed in a wide range of installation environments, particularly in a narrow space under a cabinet, due to the installation direction of the water purifier using the heating system 200 according to the above embodiment.

According to the water purifier disclosed by the embodiment of the invention, the functions of water purification and heating are integrated, and the water purifier can be vertically installed or horizontally installed according to the actual installation environment without influencing the outlet water temperature.

In some embodiments, as shown in fig. 1, the water purifier may further include a water pump 510, the water pump 510 is connected to the filtration system 100, the water pump 510 is disposed upstream of the purified water outlet 105 of the filtration system 100, the water pump 510 is used for driving water to flow from the raw water inlet 101 of the filtration system 100 to the purified water outlet 105 of the filtration system 100, and the water pump 510 is used for driving water to be discharged from the water outlet 222 of the heating system 200.

The following continues to describe the heating system 200 of an embodiment of the present invention.

In some embodiments, as shown in fig. 14, the water inlet 221 and the water outlet 222 may be disposed diagonally to a front surface of the heating system, the front surface being adjacent to the first side 212 and the bottom 211, respectively. Therefore, the water inlet 221 is close to the bottom surface 211, the water outlet 222 is close to the top surface, water can be sufficiently heated after flowing into the tank body 210 from the water inlet 221, and the temperature of the water flowing out from the water outlet 222 is high enough and is not easily influenced by the water flow of the water inlet 221.

In some embodiments, as shown in fig. 14, the can 210 includes: a can body 213, an upper end cap 214 and a lower end cap 215, both ends of the can body 213 being open, the upper end cap 214 being mounted to the upper end of the can body 213 and closing the upper end of the can body 213, the lower end cap 215 being mounted to the lower end of the can body 213 and closing the lower end of the can body 213. The joint of the upper end cover 214 and the tank body 213 is provided with a sealing structure, and the joint of the lower end cover 215 and the tank body 213 is provided with a sealing structure.

In the first flush mode, the water pump 510 is on, the clean water control valve 562 is off, the heating system 200 is off, the waste water valve 567 is on, and the vent valve 566 is off. In this mode, raw water is driven by the water pump 510 to flow in from the raw water inlet 101 and then to be discharged from the waste water outlet 104, thereby preventing impurities in the filter system 100 from entering the heating system 200 at the time of initial use.

As shown in table 1, in the flush mode, the water pump 510 is turned on, the clean water control valve 562 is turned off, and the waste water valve 567 is turned on. In this mode, raw water is driven by the water pump 510 to flow in from the raw water inlet 101 and then to be discharged from the waste water outlet 104, thereby preventing impurities deposited in the filter system 100 from flowing downstream.

If both the heating system 200 and the vent valve 566 are in an open state, it is determined that the temperature of the heating system 200 is greater than or equal to the second target temperature, and both the heating system 200 and the vent valve 566 are switched to a closed state; wherein the second target temperature is higher than the first target temperature.

In other words, whether the operating state of the heating system 200 and the exhaust valve 566 needs to be switched is determined based on the current operating state of the heating system 200 and the exhaust valve 566 and the temperature of the heating system 200.

In some embodiments, the first target temperature is T1 and the second target temperature is T2, satisfying: t1 is more than or equal to 65 ℃ and less than or equal to 75 ℃, and T2 is more than or equal to 90 ℃ and less than or equal to 100 ℃. In other words, in the relatively low temperature region, the heating system 200 is required to be turned on to heat the purified water, and the vent valve 566 is opened to prevent the pressure in the heating system 200 from being too high; to a relatively high temperature interval, the heating system 200 and the vent valve 566 may be closed based on a higher threshold.

In other words, whether the operating state of the heating system 200 needs to be switched needs to be determined based on the current operating state of the heating system 200 and the temperature of the heating system 200.

In some embodiments, the third target temperature is T3 and the fourth target temperature is T4, satisfying: t3 is more than or equal to 65 ℃ and less than or equal to 75 ℃, and T4 is more than or equal to 76 ℃ and less than or equal to 85 ℃. In other words, in the relatively low temperature region, the heating system 200 needs to be turned on to heat the purified water; to a relatively high temperature interval, the heating system 200 may be shut down based on a higher threshold.

In a specific embodiment, T3 is 70 ℃ and T4 is 80 ℃.

In embodiments where the water drive system includes a water pump 510, the water drive system being on indicates that the water pump 510 is on; in embodiments where the water drive system includes a water pump 510 and a water pump inlet valve 568, the water drive system being on indicates that the water pump 510 is on and the water pump inlet valve 568 is on.

As shown in fig. 23, the control method of the water purifier according to the embodiment of the present invention includes steps 10 to 40.

And 10, collecting the temperature of the heating system 200 of the water purifier.

The heating system 200 of the water purifier is used to heat purified water inside thereof, and the heating system 200 may be equipped with a temperature sensor for collecting the temperature of water of the heating system 200, in which the temperature of water in the middle region of the heating system 200 is preferably collected to reduce temperature deviation caused by convection of cold and hot water.

Step 20, the current status of the water purifier vent valve 566 and the heating system 200 is determined.

The water purifier vent valve 566 is electrically connected to the water purifier control, and the heating system 200 is also electrically connected to the water purifier control, which may record or monitor the current status of the vent valve 566 and the heating system 200, such as whether the vent valve 566 is open or closed and whether the heating system 200 is open or closed.

And step 30, determining the working mode of the water purifier.

The working modes of the water purifier comprise a water production mode and a non-water production mode.

The water preparation mode indicates that at least one water supply port of the water purifier is in an open state, for example, the first water supply port is in an open state, and the user is taking hot water, or the second water supply port is in an open state, and the user is taking normal-temperature purified water, and in both states, at least the filtration system 100 needs to prepare water.

The non-water production mode indicates that each water supply port of the water purifier is in a closed state.

Step 40, control of the vent valve 566 and the heating system 200 based on the temperature of the heating system 200, the current state of the vent valve 566 and the heating system 200, and the operating mode of the water purifier.

In other words, whether the operating states of the heating system 200 and the exhaust valve 566 need to be switched is determined based on the current operating states of the heating system 200 and the exhaust valve 566, the temperature of the heating system 200, and the operating mode of the water purifier.

It should be noted that, in the related art, the switching control of the operating state of the heating system is generally performed only according to the temperature thereof, or according to the temperature and the water level. This control method may result in insufficient hot water supply or a defect in the safety of the device during actual use.

The control method of the water purifier according to the embodiment of the present invention can ensure the supply amount of hot water while ensuring safety by comprehensively considering the current operating states of the heating system 200 and the exhaust valve 566, the temperature of the heating system 200, and the operating mode of the water purifier, particularly, the current operating states of the heating system 200 and the exhaust valve 566.

In some embodiments, step 40, controlling the vent valve 566 and the heating system 200 based on the temperature of the heating system 200, the current state of the vent valve 566 and the heating system 200, and the operating mode of the water purifier includes: if the water purifier is in the non-water production mode and the heating system 200 and the exhaust valve 566 are both in the closed state, it is determined that the temperature of the heating system 200 is less than the first target temperature T1, and the heating system 200 and the exhaust valve 566 are both controlled to switch to the open state.

As shown in fig. 21, when the water purifier is not used to take water, that is, in the treatment standby state, if the temperature of the heating system 200 is lower than the first target temperature T1, it means that the temperature of the water in the heating system 200 is insufficient, hot water can be prepared in advance by turning on the heating system 200, so that when the user needs to take hot water, there is instant hot water, and the air discharge valve 566 is turned on, so that the pressure in the heating system 200 can be prevented from suddenly rising during the heating process, and thus the safety of the water purifier is high.

In some embodiments, step 40, controlling the vent valve 566 and the heating system 200 based on the temperature of the heating system 200, the current state of the vent valve 566 and the heating system 200, and the operating mode of the water purifier includes: if the water purifier is in the non-water production mode and the heating system 200 and the exhaust valve 566 are both in the open state, determining that the temperature of the heating system 200 is greater than or equal to the second target temperature T2, and controlling the heating system 200 and the exhaust valve 566 to be switched to the closed state; wherein the second target temperature is higher than the first target temperature.

As shown in fig. 21, when the water purifier is not being supplied with water, i.e., in the treatment standby state, if the temperature of the heating system 200 is greater than or equal to the second target temperature T2, it means that the temperature of the water in the heating system 200 is sufficiently high, and the heating system 200 and the exhaust valve 566 are closed to prevent the water from being dried.

In some embodiments, the first target temperature is T1 and the second target temperature is T2, satisfying: t1 is more than or equal to 65 ℃ and less than or equal to 75 ℃, and T2 is more than or equal to 90 ℃ and less than or equal to 100 ℃.

In other words, in the relatively low temperature region, the heating system 200 is required to be turned on to heat the purified water, and the vent valve 566 is opened to prevent the pressure in the heating system 200 from being too high; to a relatively high temperature interval, the heating system 200 and the exhaust valve 566 may be closed based on a higher temperature threshold.

In a specific embodiment, T1 is 70 ℃ and T2 is 95 ℃.

In some embodiments, step 40, controlling the vent valve 566 and the heating system 200 based on the temperature of the heating system 200, the current state of the vent valve 566 and the heating system 200, and the operating mode of the water purifier includes: it is determined that the water purifier is in the water producing mode and the exhaust valve 566 is controlled to be closed.

In other words, no matter the water purifier is used for producing pure water at normal temperature or hot water, the exhaust valve 566 is controlled to be closed, and when the water is produced, the exhaust valve 566 is closed, so that the heating system 200 forms a closed environment, and the water pump 510 can push the hot water out of the water outlet 222 at the upper part; in the case of cooling water, since the water purifier is operated, the waste water may be discharged from the waste water inlet 104, and the exhaust valve 566 is closed, the waste water is prevented from being inversely flowed into the heating system 200.
