Description

TECHNICAL FIELD

[0001] The present application relates to a stove, in particular to a gas stove with a water vapor system. BACKGROUND

[0002] The patent application with publication number CN111947184A discloses a gas stove. The gas stove has a stove body and a combustible gas burner.

[0003] The stove body has an inner ring heat absorbing water tank of a hearth, an outer ring heat absorbing water tank of a hearth, and an external transverse heat absorbing water tank. The external transverse heat absorbing water tank has an inner rectangular cylinder and an outer rectangular cylinder. The space between the outer surface of the inner rectangular cylinder and the inner surface of the outer rectangular cylinder is the space for containing water in the external transverse heat absorbing water tank. The bottom of the inner ring heat absorbing water tank of the hearth is connected to the bottom of the outer ring heat absorbing water tank of the hearth. The outer ring heat absorbing water tank of the hearth is connected to the space for containing water in the external transverse heat absorbing water tank. A short pipe connects the top space of the inner ring heat absorbing water tank of the hearth to the top space of the outer ring heat absorbing water tank of the hearth. The space between the outer wall plate of the inner ring heat absorbing water tank of the hearth and the inner wall plate of the outer ring heat absorbing water tank of the hearth is the internal annular flue gas passage of the stove body. The inner rectangular cylinder is the transverse flue gas passage of the stove body. The internal annular flue gas passage is connected to the space surrounded by the inner rectangular cylinder as the transverse flue gas passage. The top wall plate of the inner ring heat absorbing water tank of the hearth extends outwardly and is sealingly welded to the inner cylindrical wall plate of the outer ring heat absorbing water tank of the hearth to form an annular top plate, which closes the upper part of the internal flue gas passage. Multiple through holes are opened in the annular top plate, or three through holes are opened in the annular top plate away from the external transverse heat absorbing water tank. The space surrounded by the part of the inner cylindrical wall plate of the outer ring heat absorbing water tank of the hearth above the annular top plate constitutes an upper hearth, which is connected to the internal annular flue gas passage. Multiple communication pipes are sealingly welded between the top wall plate and the bottom wall plate of the inner rectangular cylinder of the external transverse heat absorbing water tank to connect the top space and the bottom space in the outer rectangular cylinder outside the inner rectangular cylinder, which can improve the heating effect of the high-temperature gas generated by combustion on the water in the external transverse heat absorbing water tank.

[0004] The stove body also has an internal transverse heat absorbing water tank. The internal transverse heat absorbing water tank has a top wall plate and a bottom wall plate, and the internal transverse heat absorbing water tank is connected to the inner ring heat absorbing water tank of the hearth. The space surrounded by the part of the inner cylindrical wall plate of the inner ring heat absorbing water tank of the hearth above the top wall plate of the internal transverse heat absorbing water tank constitutes a lower hearth. The upper hearth and the lower hearth are connected.

[0005] The combustible gas burner has at least one air-gas mixture conduit for delivering air-gas mixture for main fire combustion and one air-gas mixture conduit for delivering air-gas mixture for common fire combustion, which are located in the internal transverse heat-absorbing water tank and in the water in the internal transverse heat-absorbing water tank.

[0006] The gas stove does not involve a water vapor system. SUMMARY

[0007] The present application provides a gas stove with a water vapor system.

[0008] The gas stove with a water vapor system of the present application has a stove body with a heat-absorbing water tank, the space defined by the inner wall of the heat-absorbing water tank being a furnace; characterized in that it further has a water vapor system comprising:

[0009] a tap pipe in communication with a municipal tap water pipe network, the outlet end of the tap pipe being connected with a first inlet of a first hollow closed shell pipe, the first outlet of the first hollow closed shell pipe being connected with the inlet end of a first cold water pipe, the outlet end of the first cold water pipe being connected with the inlet of a second hollow closed shell pipe, the first outlet of the second hollow closed shell pipe being connected with the inlet of a first float ball valve installed in a first float ball water tank, the outlet on the bottom wall of the first float ball water tank being connected with the inlet end of a second cold water pipe, the outlet end of the second cold water pipe being connected with the first cold water inlet on the outer wall of the heat-absorbing water tank, the second outlet of the second hollow closed shell pipe being connected with the inlet end of a fourth cold water pipe, the outlet end of the fourth cold water pipe being connected with the inlet of a cold water faucet, the second outlet of the first hollow closed shell pipe being connected with the inlet of a first electromagnetic valve, the outlet of the first electromagnetic valve being connected with the inlet end of a third cold water pipe, the outlet end of the third cold water pipe being connected with the second cold water inlet on the bottom wall of the heat-absorbing water tank;

[0010] a water level sensor probe installed on the outer wall of the heat-absorbing water tank, extending into the heat-absorbing water tank, and electrically connected with the electric control device of the first electromagnetic valve;

[0011] The set liquid level in the first float ball water tank is higher than the set liquid level in the heat-absorbing water tank.

[0012] The gas stove with the water vapor system of the present application, since the set liquid level in the first floating ball water tank is higher than that in the heat absorbing water tank, when the liquid level in the heat absorbing water tank is lower than the set liquid level, the first floating ball water tank and the first electromagnetic valve can simultaneously supply tap water into the heat absorbing water tank, so that the gas stove can quickly work, and the heat absorbing water tank will not be burned due to lack of water when the first floating ball water tank or the first electromagnetic valve fails; when the liquid level in the heat absorbing water tank reaches the set liquid level, the first electromagnetic valve stops supplying tap water into the heat absorbing water tank, while the first floating ball water tank continues to supply tap water into the heat absorbing water tank, when the liquid level in the heat absorbing water tank continues to rise to the same set liquid level as that in the first floating ball water tank, the first floating ball water tank stops supplying tap water into the heat absorbing water tank, thereby avoiding frequent operation of the first electromagnetic valve and saving energy.

[0013] The water vapor system further comprises:

[0014] A first water vapor discharge pipe is arranged in the heat absorbing water tank, the top end opening is above the water surface in the heat absorbing water tank, the bottom end is connected with the inlet of a third hollow closed shell pipe, the first outlet of the third hollow closed shell pipe is connected with the inlet end of a first vapor pipe, the outlet end of the first vapor pipe is connected with the inlet on the top wall of the first floating ball water tank, the second outlet of the third hollow closed shell pipe is connected with the inlet end of a second vapor pipe, the outlet end of the second vapor pipe is inserted into the first hole on the top wall of a fourth hollow closed shell pipe, the third outlet of the third hollow closed shell pipe is connected with the inlet end of a first drain pipe, the outlet end of the first drain pipe is inserted into the second hole on the top wall of the fourth hollow closed shell pipe, and the inner cavity of the fourth hollow closed shell pipe is connected with the atmosphere.

[0016] The outlet on the fourth hollow closed shell pipe wall is connected with the inlet end of a second drain pipe, the outlet end of the second drain pipe is connected with the inlet on the outer wall of a cooking surface drain pipe, and the top end opening of the cooking surface drain pipe is connected with the opening on the top plate of the shell of the stove.

[0017] The water vapor system further comprises:

[0018] A first hot water pipe, the inlet end of which is connected with the outlet on the bottom wall of the heat absorbing water tank, the outlet end of which is connected with the inlet of a first water pump, the outlet of which is connected with the inlet end of a fifth hollow closed shell pipe, the first outlet of which is connected with the inlet of a second electromagnetic valve, the outlet of which is connected with the inlet end of a second hot water pipe, the outlet end of which is connected with the inlet of a second float ball valve installed in a hot water float ball tank, the second outlet of the fifth hollow closed shell pipe is connected with the inlet end of a third hot water pipe, and the outlet end of the third hot water pipe is connected with the inlet on the outer wall of the heat absorbing water tank.

[0019] A temperature control sensor probe is installed on the outer wall of the fifth hollow closed shell pipe, extends into the fifth hollow closed shell pipe, and is electrically connected with the electric control device of the second electromagnetic valve.

[0020] In this way, the hot water in the heat absorbing water tank is extracted when it reaches the set temperature, which is convenient for use.

[0021] The water vapor system further comprises:

[0022] A first water pipe, the inlet end of which is connected with the opening on the bottom wall of a cooking surface water tank, the outlet end of which is connected with the inlet of a second water pump, the outlet of which is connected with the inlet end of a second water pipe, the outlet end of which is connected with the inlet of a second check valve, and the outlet of the second check valve is connected with the second inlet of the first hollow closed shell pipe.

[0023] In this way, the water in the cooking surface water tank is pressurized by the second water pump and flows into the first hollow closed shell pipe, and then can enter the heat absorbing water tank, thereby preventing the heat absorbing water tank from being burned out due to water supply interruption when the tap water pipe connected with the municipal tap water pipe network cannot supply water to the heat absorbing water tank.

[0024] The water vapor system further comprises:

[0060] The inlet end of the external flue 50 is connected with the internal annular flue of the stove.

[0061] The water vapor system of the gas stove according to the present application operates as follows:

[0062] Referring to Figure 2 and Figure 5 Tap water flows into the first four-way pipe 301 from the first inlet of the first four-way pipe 301 through the tap water pipe 100 and the first one-way valve 201, and then flows out of the first four-way pipe 301 from the two outlets of the first four-way pipe 301.

[0063] The tap water from the first outlet of the first four-way valve 301 flows into the first inlet of the first three-way valve 901 through the first cold water pipe 501, and then flows into the inlet of the first float ball valve 101 installed in the first float ball tank 300 from the first outlet of the first three-way valve 901. When the liquid level in the first float ball tank 300 is lower than the set level, the first float ball valve 101 is opened, and the tap water flows into the first float ball tank 300 from the outlet of the first float ball valve 101, and then flows into the outer ring heat absorbing water tank of the hearth of the stove 1 through the second cold water pipe 502. When the liquid level in the first float ball tank 300 reaches the set level, the first float ball valve 101 is closed, and the tap water is stopped from being supplied into the first float ball tank 300. The tap water from the second outlet of the first three-way valve 901 flows into the inlet of the cold water tap 200 through the fourth cold water pipe 504. When the cold water tap 200 is manually opened for use of the tap water, the tap water flows out of the cold water tap 200.

[0064] The tap water from the second outlet of the first four-way valve 301 flows into the inlet of the first electromagnetic valve 401. When the water level sensor probe 4 installed on the outer wall of the outer ring heat absorbing water tank of the hearth of the stove 1 detects that the liquid level in the outer ring heat absorbing water tank of the hearth is lower than the height position of the probe extending into the outer ring heat absorbing water tank, i.e. the set level, the first electromagnetic valve 401 is opened, and the tap water flows out of the outlet of the first electromagnetic valve 401, and then flows into the outer ring heat absorbing water tank of the hearth of the stove 1 through the third cold water pipe 503. When the water level sensor probe 4 detects that the liquid level in the outer ring heat absorbing water tank of the hearth reaches the set level, the first electromagnetic valve 401 is closed, and the tap water is stopped from being supplied into the outer ring heat absorbing water tank of the hearth.

[0065] The set levels in the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank are the same. The set level in the first float ball tank 300 is higher than the set levels in the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank. In this way, when the liquid levels in the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank are lower than the set levels, the tap water can be simultaneously supplied into the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank through the first float ball tank 300 and the first electromagnetic valve 401; when the liquid levels in the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank reach the set levels, the tap water can be stopped from being supplied into the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank through the first electromagnetic valve 401, while the tap water can continue to be supplied into the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank through the first float ball tank 300; when the liquid levels in the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank continue to rise to the same level as the set level in the first float ball tank 300, the first float ball tank 300 stops supplying the tap water into the inner ring heat absorbing water tank, the outer ring heat absorbing water tank of the hearth and the internal transverse heat absorbing water tank.

[0066] Hot water flowing out of the outlet on the bottom wall of the heat absorbing water tank from the outer ring of the hearth of the cooking body 1 flows into the first hot water pipe 505, and then into the first water pump 6 after being pressurized, and then flows out of the five-way pipe 602 from the four outlets of the five-way pipe 602:

[0067] Hot water flowing out of the first outlet of the five-way pipe 602 flows to the inlet of the second solenoid valve 402, and when the temperature control sensor probe 7 installed on the outer wall of the five-way pipe 602 detects that the temperature of the hot water in the five-way pipe 602 is higher than the set temperature, the second solenoid valve 402 opens, and the hot water flows out of the first outlet of the five-way pipe 602, and then flows to the inlet of the second float valve 103 installed in the hot water floating ball water tank 500 in sequence through the second solenoid valve 402 and the second hot water pipe 506, and when the liquid level in the hot water floating ball water tank 500 is lower than the set level, the second float valve 103 opens, and the hot water flows into the hot water floating ball water tank 500 from the outlet of the second float valve 103, and when the liquid level in the hot water floating ball water tank 500 reaches the set level, the second float valve 103 closes, stopping the replenishment of hot water into the hot water floating ball water tank 500, and when the temperature control sensor probe 7 detects that the temperature of the hot water in the five-way pipe 602 is lower than the set temperature, the second solenoid valve 402 closes.

[0068] Hot water flowing out of the second outlet of the five-way pipe 602 flows into the heat absorbing water tank of the outer ring of the hearth of the cooking body 1 through the third hot water pipe 507. The first flow limiting orifice plate installed in the second outlet of the five-way pipe 602 limits the flow of hot water to the heat absorbing water tank of the outer ring of the hearth of the cooking body 1, preventing most of the hot water from flowing into the heat absorbing water tank of the outer ring of the hearth of the cooking body 1 when replenishing hot water into the hot water floating ball water tank 500, and only a small amount of hot water flows into the hot water floating ball water tank 500 through the second float valve 103, affecting the speed of replenishing hot water into the hot water floating ball water tank 500.

[0069] Hot water flowing out of the third outlet of the five-way pipe 602 flows to the inlet of the hot water faucet 600 through the fourth hot water pipe 508, and when hot water is needed, the hot water faucet 600 is manually opened, and hot water flows out of the hot water faucet 600.

[0070] Hot water flowing out of the fourth outlet of the five-way pipe 602 flows to the inlet of the first drain valve 701, and when it is necessary to drain the sewage in the bottom of the heat absorbing water tank, the first drain valve 701 can be manually opened.
