[0003] Currently, the combustion chamber in gas dryers on the market only heats air for drying clothes, but cannot heat water for hot water heating. It fails to fully utilize the multifunctional application scenarios and market value maximization brought by the thermal energy of gas combustion itself. Therefore, gas is lacking in combustion function, practicality and market value. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figure 1 The embodiment of the present invention provides a gas hot water heating clothes dryer, comprising a drum 40 and two combustion chambers, wherein the first combustion chamber 86 is connected to the air inlet of the drum 40 through a first combustion exhaust channel, and the second combustion chamber 87 is connected to the air inlet of the drum 40 through a second combustion exhaust channel. The first combustion chamber 86 is used to provide hot water for heating and hot water for the bathroom, and one of the first combustion chamber 86 and the second combustion chamber 87 serves as a heat source for drying. When the first combustion chamber 86 provides hot water for heating, or provides hot water for bathing, it can also provide hot air to the drum 40 for drying, so that thermal energy is fully utilized and energy consumption is reduced. The second combustion chamber 87 can perform drying alone. When the first combustion chamber 86 does not provide hot water for heating and hot water for the bathroom, the second combustion chamber 87 can serve as a drying heat source to provide the hot air required for drying. The gas hot water heating clothes dryer of the embodiment of the utility model integrates the three functions of drying clothes, hot water and heating, improves the integration of combustion products, and replaces the single combustion system products of existing water heaters and wall-mounted boilers. The multifunctional integrated combustion system control improves the practicality of gas combustion and increases the market value of gas combustion, achieving three uses in one machine.

[0025] The gas-fired hot water heating clothes dryer of this embodiment is equipped with an exhaust device 20 at the exhaust end of the drum 40. The exhaust end of the drum 40 is connected to an exhaust duct. When the exhaust device 20 is activated, the centrifugal force generated by the drying process causes the hot and humid air to be discharged through the exhaust duct. A first temperature and humidity sensor 91 can be installed in the exhaust duct, and a second temperature and humidity sensor 92 can be installed at the air inlet end of the drum 40. By monitoring changes in temperature and humidity during the drying process, this can provide a basis for adjusting drying parameters.

[0026] In the gas-fired hot water heating clothes dryer of the present embodiment, the first temperature and humidity sensor 91 and the second temperature sensor 92 can monitor temperature and humidity changes during the drying process. Based on the first temperature and humidity detected by the first temperature and humidity sensor 91 and the second temperature and humidity detected by the second temperature and humidity sensor 92, the drying process can be controlled to enter different drying stages, each with different drying parameters. This helps save drying time and energy consumption, and can prevent damage to fabrics and energy waste caused by overdrying.

[0027] For example, the drying stage may include a heating stage, a constant speed drying stage, a speed reduction drying stage and a cold air blowing stage. In the heating stage, the drum 40 rotates at a first speed. In the constant speed drying stage, the drum 40 rotates at a second speed. In the speed reduction drying stage, the drum 40 rotates at a third speed. In the cold air blowing stage, the drum 40 rotates at a fourth speed. The second speed is lower than the first speed. The third and fourth speeds are lower than the second speed. The third speed and the fourth speed are the same or different.

[0028] Assuming factors like the laundry load and drum size remain constant, and the temperature remains consistent, the drying time is inversely proportional to the drum's rotation speed; that is, the higher the speed, the faster the drying rate. Therefore, during the warming phase, the drum's rotation speed is used at a high speed to fully distribute the laundry and increase the exchange area between the laundry and the drying airflow. During the constant-speed drying phase, the moisture content of the laundry decreases, reducing its mass, so the drum's rotation speed is used at a moderate speed. During the decreasing-speed drying phase and the cold-air drying phase, the laundry mass is even lower, so the drum's rotation speed in these two phases should be slightly reduced compared to the constant-speed drying phase.

[0029] In some embodiments, the first speed ranges from 52 rpm to 58 rpm; the second speed ranges from 45 rpm to 50 rpm; and the third and fourth speeds range from 42 rpm to 48 rpm. During the warming stage, the speed of the drum 40 is between 52 rpm and 58 rpm, which can fully spread the clothes and increase the exchange area between the clothes and the drying airflow. The drum 40 rotates at a high speed. During the constant-speed drying stage, the moisture content of the clothes decreases and the weight decreases. The speed of the drum 40 is between 45 rpm and 50 rpm, ensuring that the clothes are fully spread while reducing power output, lowering energy consumption, and helping to flatten the clothes. During the deceleration drying stage and the cold air blowing stage, the weight of the clothes is even smaller. Therefore, the speed of the drum 40 used in these two stages should be slightly lower than that in the constant-speed drying stage, specifically between 42 rpm and 48 rpm. This ensures that the clothes are fully spread while further reducing power output, lowering energy consumption, and helping to flatten the clothes.

[0030] In some embodiments, the exhaust device 20 provides a first wind speed during the heating stage and the speed-decreasing drying stage; and provides a second wind speed during the constant-speed drying stage and the cold air blowing stage, which is higher than the first wind speed.

[0031] The air velocity provided by the exhaust device 20 affects the residence time of the drying airflow within the drum, thereby impacting the drying efficiency of clothes. The duration of dry, hot air remaining within the drum 40 is equal to the quotient of the volume of the drum 40 divided by the velocity of the air driven by the exhaust device 20. The dry, hot air should remain within the drum 40 for an appropriate period of time. Excessively high or low air velocity in the exhaust device 20 is detrimental to improving drying efficiency.

[0032] In the embodiment of the present invention, in the heating stage and the speed-decreasing drying stage, the exhaust device 20 can adopt a low wind speed to ensure that the hot and dry air has sufficient contact with the fabric, ensure the high moisture content of the exhaust gas, and improve the energy utilization efficiency; while in the constant speed drying stage and the cold air blowing stage, the exhaust device 20 can adopt a higher wind speed to discharge the relatively moist gas in time, saving drying time.

[0033] The maximum power of the first combustion chamber 86 and the maximum power of the second combustion chamber 87 can be the same or different. For example, the maximum power of the second combustion chamber 87 can be less than the maximum power of the first combustion chamber 86.

[0034] In some embodiments, when the second combustion chamber 87 is used as the drying heat source, in the heating stage, the second combustion chamber 87 adopts the first combustion gear; in the constant speed drying stage, the second combustion chamber 87 adopts the second combustion gear; in the speed reduction drying stage, the second combustion chamber 87 adopts the third combustion gear; in the cold air blowing stage, the second combustion chamber 87 is closed and stops working; the heat provided by the first combustion gear, the second combustion gear and the third combustion gear decreases successively.

[0035] See also Figure 1 The second combustion chamber 87 has a drying fire bar 84. In order to quickly heat up and dry the fabric, the drying fire bar 84 uses different fire levels to provide different amounts of heat at different stages of the drying process. The higher the fire level, the higher the heat provided. During the heating stage, the drying fire row 84 is adjusted to the high fire gear, combined with the low wind speed operation of the exhaust device 20, the dry hot air in the drum 40 has sufficient contact with the fabric, ensuring rapid heating in a short time; during the constant speed drying stage, the drying fire row 84 is adjusted to the medium fire gear, combined with the low wind speed operation of the exhaust device 20, the dry hot air in the drum 40 has sufficient contact with the fabric, ensuring that the fabric is continuously dried within the effective time; during the speed reduction drying stage, the drying fire row 84 is adjusted to the low fire gear, combined with the medium wind speed operation of the exhaust device 20, to ensure that the temperature of the clothes is too high and the clothing tissue is damaged; during the cold air blowing stage, the drying fire row 84 is closed and stops working, combined with the high wind speed operation of the exhaust device 20, to quickly discharge the relatively humid gas and cool the clothes, saving time.

[0036] In some embodiments, in the four stages of drying, the drum 40 rotates in a forward and reverse phase alternating manner. The forward and reverse alternating rotation of the drum 40 can shake out the clothes to a greater extent, which is beneficial to improving the drying efficiency, drying uniformity and the smoothness of the appearance of the clothes after drying, and reducing energy consumption. The forward and reverse alternating rotation ratio of the drum 40 can be set to 1:1. When the drum 40 rotates forward and reverse, it needs to stop. The rotation frequency, that is, the rhythm of the rotation, can be, for example, 15 / 5. That is, it rotates for 15 seconds and stops for 5 seconds. In a specific implementation, the drum 40 can rotate forward for 15 seconds, stop for 5 seconds, reverse for 15 seconds, and stop for 5 seconds, and so on.

[0037] In some embodiments, see Figure 1 The gas hot water heating dryer also includes a condensation exchanger 62 and a water pump 69. The condensation exchanger 62 is arranged on the first combustion exhaust channel. The water pump 69 includes a first port, a second port and a third port. The first port is connected to the bathroom water inlet, the second port is connected to the heating return pipe, and the third port is the water outlet. The preheating inlet of the condensation exchanger 62 is connected through the water inlet pipe 110. The preheating outlet of the condensation exchanger 62 is connected to the water outlet pipe 120, and the water outlet pipe 120 partially surrounds the outside of the first combustion chamber 86.

[0038] In some embodiments, the water pump 69 also includes a fourth port, a fifth port, a sixth port and a seventh port. The fourth port is connected to the expansion water tank 70. The fifth port is provided with an exhaust valve 71 for removing air and draining water. The sixth port is provided with a heating safety pressure relief valve 72. The seventh port is a water pump drain port 74 for discharging impurities and pollutants generated by the water pump 69 during operation.

[0039] The water pump 69 is provided with seven ports, the first port of which is the bathroom water inlet 63, connected to the bathroom water inlet water line, the second port is connected to the heating return pipe, the third port is the water outlet, and the third port is connected to the condensation exchanger 62 through the water inlet pipe 110. The fourth port is provided with a connection to the expansion water tank 70, which mainly maintains the internal water system pressure stability; the fifth port of the water pump 69 is provided with an exhaust valve 71, which is mainly used to remove air and drain water in the internal water system to ensure that hot water can flow smoothly. When the pressure in the system is too high, the exhaust valve 71 can also release pressure to protect the safety of the entire system; the sixth port of the water pump 69 is provided with a heating safety pressure relief valve 72, which is a safety protection valve that mainly protects the pressure of the internal system. When the pressure is too high, the valve is automatically opened to release the excessive pressure to protect the safe operation of the heating; the seventh port of the water pump 69 is provided with a water pump sewage outlet 74, which is mainly used to discharge impurities and pollutants generated by the water pump 69 during long-term work, such as air, rust, etc., to avoid failure of the water pump 69.

[0040] In some embodiments of the present invention, the speed of water pump 69 can be adjusted based on the ambient water pressure to keep the water supply pressure within a set range. Water pump 69 ensures the pressure of the entire water supply, resolving sudden changes in temperature. A pressure sensor 54 is provided at the outlet end of the water outlet pipe 120 to monitor the outlet pressure in real time, preventing it from being too high or too low. Water pump 69 can control the water supply pressure within a set range.

[0041] A bathroom water inlet valve 64 is provided on the bathroom water inlet waterway, one end of which is the bathroom water inlet 63, and the water outlet of the water pump 69 is connected to the condensation exchanger 62 through the water inlet pipe 110 to form a preheated water circuit. Preheating through the condensation exchanger 62 can make full use of the heat generated by combustion and save energy.

[0042] The other end of the condensate exchanger 62 is connected to the condensate collection box 60 via a condensate pipe. The condensate exchanger 62 primarily serves as a preheating device for the hot water supply, thereby reducing energy consumption. The condensate collection box 60 primarily collects condensate generated during the preheating phase. One end of the condensate collection box 60 is equipped with a condensate outlet 59 for condensate discharge and a condensate box cleaning port 61 for cleaning impurities accumulated over time. The outlet pipe 120, exiting the condensate exchanger 62, wraps around the outside of the first combustion chamber 86 for a certain length. During this time, the outer pipe around the first combustion chamber 86 primarily serves as the primary heating device. After the outlet pipe 120 wraps around the first combustion chamber, a main outlet thermostat 55 is installed near the outlet end to monitor the temperature and prevent excessive heating. A pressure sensor 54 is installed near the outlet end of the outlet pipe 120, which monitors the pressure and prevents excessive water pressure. The other end of the pressure sensor 54 is connected to a three-way valve 53, which also connects the first and second water channels. The three-way valve 53 is mainly used to control the water circuit. The first water circuit is the bathroom hot water supply system. The first water circuit is equipped with a bathroom outlet water temperature sensor 52 and a bathroom outlet valve 51. The outlet end of the first water circuit is the bathroom outlet 50. The bathroom outlet water temperature sensor 52 monitors the outlet water temperature in real time to meet the bathroom outlet water temperature requirement. The second water circuit is the heating system. The second water circuit is equipped with a heating outlet water temperature sensor 56 and a heating outlet valve (57). The outlet end of the second water circuit is the heating outlet 58. The heating outlet water temperature sensor 56 monitors the outlet water temperature in real time to meet the heating temperature requirement.

[0043] The heating system and the bathroom hot water supply system share a combustion hot water system. The second port of the water pump 69 is connected to the heating return pipe. One end of the heating return pipe is the heating return port 65. The heating return pipe is equipped with a magnetic filter 66, a heating return valve 67, and a heating return water temperature sensor 68, thereby forming an independent return water circuit for heating. Impurities in the heating return water are filtered by the magnetic filter 66 to ensure the quality of the water. By connecting to the second port of the water pump 69, an independent return water circuit for heating is formed. After entering the water pump 69, the heating combustion system and the bathroom hot water supply combustion system share the first combustion chamber. Finally, after passing through the three-way valve 53, it is connected to the second water circuit and enters the heating system control. In the second water circuit, the heating outlet water temperature sensor 56 monitors in real time to meet the heating temperature requirements.

[0044] An indoor thermostat 79 is provided inside the device for monitoring changes in the indoor ambient temperature. The indoor thermostat 79 can adjust the heating supply demand according to changes in the ambient temperature.

[0045] In some embodiments, the first combustion chamber 86 and the second combustion chamber 87 are connected to the gas pipe 100 through the first branch pipe and the second branch pipe respectively. The gas pipe 100 is provided with a gas filter 76, a gas proportional valve 77 and a first solenoid valve 78 in sequence along the air intake direction. The first solenoid valve 78 is the main air intake control switch valve. The second solenoid valve 80 is provided on the first branch pipe, and the third solenoid valve 83 is provided on the second branch pipe.

[0046] During use of the gas-fired hot water heating clothes dryer of the present embodiment of the utility model: if the first combustion chamber 86 is shut down during drying, the second combustion chamber 87 is activated and used as the drying heat source. If the first combustion chamber 86 is shut down due to, for example, the completion of its operation, the second combustion chamber 87 is activated to continue the drying process. For example, if the first combustion chamber 86 is activated for bathing while drying is also being performed, and if the bathing process is not yet complete, the second combustion chamber 87 can be activated to continue the drying process, avoiding interruptions.

[0047] When the second combustion chamber 87 is working independently, the first combustion chamber 86 stops working: the gas inlet 75 is connected to the external gas source, and the external gas is filtered by the gas filter 76 and enters the gas proportional valve 77, while the other end is connected to the gas pipe 100 and enters the first solenoid valve 78, where the first solenoid valve 78 is the main control switch valve for air intake; at this time, the second solenoid valve 80 closes the channel, the first combustion chamber 86 does not work, and the third solenoid valve 83 opens the channel, and the external gas enters the clothes drying fire grate 84 in the second combustion chamber 87 through the gas pipe 100, and burns under the ignition of the second ignition needle 85. The hot gas generated passes through the upper part of the second combustion chamber 87 and enters the common combustion chamber exhaust channel 88, and directly passes to the drum air intake channel 89. Finally, the clothes enter the drum 40 from the air intake channel hole 891 of the drum air intake channel 89, and the clothes are dried by the air heated by the combustion of gas. The moisture in the clothes is heated and turned into water vapor. Under the action of the exhaust device 20, it finally passes through the three layers of filtration of the lint collector 30 and is discharged out of the cavity through the exhaust pipe 10. The water in the bathroom water supply will not be heated, so the pressure in the water pipe will not increase, thereby avoiding environmental safety hazards for users.

[0048] When the first combustion chamber 86 works independently, the second combustion chamber 87 is not started: the external gas source is connected to the gas inlet 75, and the external gas passes through the gas filter 76 and enters the gas proportional valve 77 after filtration. The other end of the gas proportional valve 77 is connected to the gas pipe 100 and enters the first solenoid valve 78, where the first solenoid valve 78 is the main control switch valve; at this time, the second solenoid valve 80 opens the channel, and the third solenoid valve 83 closes the channel, so that the external gas enters the hot water fire exhaust 81 in the hot water heating combustion system through the gas pipe 100, and is ignited by the first ignition needle 82 for gas combustion. The hot gas generated passes through the top of the first combustion chamber 86 into the common combustion chamber exhaust channel 88, directly passes through the drum air inlet channel 89, and finally enters the drum 40 from the air inlet channel hole 891 on the drum air inlet channel 89. The clothes are dried by the air heated by the gas combustion, and the moisture in the clothes is heated and turned into water vapor. Under the action of the exhaust device 20, it finally passes through the three layers of lint collector 30 and is discharged out of the cavity through the exhaust pipe 10.

[0049] At the same time, the heat energy generated by the combustion in the first combustion chamber 86 is heated by the external water in the surrounding water pipe through the heat energy exchange function, thereby realizing the function of hot water and heating supply; a three-way valve 53 is provided between the water pipe structure, and the three-way valve 53 supplies two water channels, each water channel is installed with a bathroom water outlet temperature sensor 52 and a heating water outlet temperature sensor 56, which are mainly used to accurately control the water temperature to meet the user's required temperature.

[0050] See also Figure 1 and Figure 2 During the drying process, since the rear end portion of the drum 40 is provided with a plurality of ventilation holes, these ventilation holes are connected to the exhaust device 20 and finally to the exhaust pipe 10; the centrifugal effect generated after the exhaust device 20 is started, the air with waste heat generated during the combustion process is filtered through three layers of lint collectors 30. At this time, the lint residue generated during the drying process of the clothes is collected in the lint collector 30, and the relatively clean hot and humid air during the drying process after being filtered is finally discharged out of the cavity through the exhaust pipe 10; a second temperature and humidity sensor 92 is provided at the front end portion of the drum 40, which mainly monitors the drying temperature and the humidity of the clothes in the drum 40 in real time through the second temperature and humidity sensor 92, so as to appropriately adjust the number of revolutions of the exhaust device 20 and the drum 40 to prevent deformation and deterioration of the clothes caused by excessive temperature.

[0051] When using indoor heating or taking a shower, the clothes drying function can be started at the same time. The hot air generated during heating or bathroom water use is recycled and reused and enters the drum 40 of the dryer to dry the required clothes. Therefore, when the first combustion chamber 86 is mainly used, in addition to the use functions of bathroom water and heating supply, the hot air generated by combustion can be used to achieve the function of drying clothes; the energy consumption generated by combustion required for drying clothes, the use cost and the improvement of use efficiency are saved, and energy conservation and emission reduction are truly achieved.

[0052] The embodiment of the utility model realizes three different functions of hot water, heating and clothes drying; it replaces the existing three functional products of water heater, wall-mounted boiler and clothes dryer, and therefore has stronger practicality and lower use cost than the existing products.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
