[0043] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] In a first aspect, this application provides a washing oven designed to at least partially improve the energy waste phenomenon during the operation of an ironing machine.

[0045] Figure 1 Schematic diagrams of the washing furnace in some embodiments are shown. Figure 2 It shows Figure 1 A structural diagram of the main body. Combined with... Figure 1 as well as Figure 2 The washing machine includes a body 1 and a burner 2. The body 1 has a combustion chamber 101, a water container 102 and a hot air chamber 103. The combustion chamber 101 has an air inlet and an air outlet. The water container 102 and the hot air chamber 103 are arranged sequentially around the combustion chamber 101 along the airflow direction. The burner 2 is connected to the body 1 and communicates with the air inlet of the combustion chamber 101.

[0046] The washing oven provided in this application has a combustion chamber 101 built into the main body 1. The burner 2 is connected to the main body 1 and communicates with the air inlet of the combustion chamber 101. When the burner 2 is working, fuel is burned in the combustion chamber through the burner, heating the air in the combustion chamber. The heated air is output through the air outlet of the combustion chamber. Since the water container 102 and the hot air container 103 are arranged sequentially around the combustion chamber 101 along the airflow direction, the water in the water container 102 can exchange heat with the combustion chamber 101 to provide the washing machine with the hot water required for washing and reduce the temperature inside the combustion chamber 101. The hot air container 103 also exchanges heat with the combustion chamber 101 to reduce the temperature inside the combustion chamber 101 so that the air outlet of the combustion chamber 101 can output hot flue gas that meets the requirements of the ironing machine during ironing.

[0047] The washing furnace provided in this application can simultaneously provide the hot water and hot air required for the washing system to work, that is, one set of equipment can meet the working needs of the ironing machine, thereby reducing energy waste and having great practicality.

[0048] Combination Figure 1 The washing oven provided in this application also includes a housing 3, which is generally square in structure and has a cavity inside. The main body 1 of the washing oven is placed inside the cavity of the housing 3.

[0049] Combination Figure 2 In this application, the main body 1 of the washing furnace is generally cylindrical, and a mounting portion 104 is provided at one end of the main body 1. This mounting portion 104 can be a tank structure, located axially on the main body 1 and situated in the middle of the water reservoir 102. Part of the burner 2 is assembled within the mounting portion 104, and another part of the burner 2 can extend through the end of the housing 3 for connection to a medium delivery pipeline, thereby supplying the required medium to the burner 2. In one embodiment, the medium can be natural gas to reduce environmental pollution. In other embodiments, the medium can be a gaseous or liquid medium such as coal gas, and no limitation is made here.

[0050] Figure 4 It shows Figure 2 A schematic diagram of the AA cross section, combined with Figure 1 , Figure 2 as well as Figure 4The water reservoir 102 can be a hemispherical structure, enclosing the air inlet end of the combustion chamber 101. The air inlet end of the combustion chamber 101 has the highest temperature, allowing the water in the water reservoir 102 to radiate heat with the heat source at the air inlet end of the combustion chamber 101, thus forming hot water. The water reservoir 102 is provided with a water inlet 105, which can be connected to a water supply tank 4 via a water supply pipe. The water supply tank 4 can be connected to the outer circumference of the housing 3 or can be set independently of the housing 3. The water supply tank 4 can hold cold water to replenish the water reservoir 102.

[0051] In addition, the washing machine also includes a water outlet pipe 110 and an exhaust pipe 111. The water outlet pipe 110 is connected to the water container 102 to draw out the hot water generated in the water container 102. The exhaust pipe 111 is connected to the water outlet pipe 110 to draw out the steam generated in the water container 102, thereby improving the safety of the washing machine operation.

[0052] It should be noted that the water outlet pipe can guide hot water to the washer-extractor for washing, thus providing hot water for the washing machine. Of course, this hot water can also be used for other purposes, such as providing heating, which is not limited here.

[0053] In addition, an insulation layer may be provided on the outer periphery of the water container 102 to ensure the temperature of the water in the water container so that the hot water temperature provided by the water container 102 meets the requirements.

[0054] Figure 3 It shows Figure 2 Side view diagram with burner removed. (Combined with...) Figure 2 as well as Figure 3 The washing furnace provided in this application also includes at least one first air supply pipe 5. One end of the first air supply pipe 5 is disposed outside the main body 1, and the other end passes through the water container cavity 102 and enters the air inlet of the combustion cavity 101. This allows low-temperature flue gas to be supplied to the air inlet of the combustion cavity 101 of the main body 1 through the first air supply pipe 5, thereby reducing the temperature inside the combustion cavity generated by the burner 2. In specific implementations, multiple first air supply pipes 5 are provided, spaced circumferentially around the combustion cavity 101 to increase the amount of low-temperature flue gas supplied to the air inlet of the combustion cavity 101 of the main body 1. Furthermore, the other end of the multiple first air supply pipes 5 can be arranged away from the axial direction of the hot air cavity 103. Since the multiple first air supply pipes 5 are located at the air inlet of the combustion cavity 101, this arrangement not only increases the amount of low-temperature flue gas supplied to the air inlet of the combustion cavity 101 of the main body 1 but also avoids affecting the operation of the burner 2, ensuring the normal operation of the burner 2.

[0055] Combination Figure 3In this application, the outer ends of multiple first air supply pipes 5 can be connected to a first air intake pipe 6 to share the first air inlet 61 of the first air intake pipe 6.

[0056] Figure 5 It shows Figure 2 A schematic diagram of the BB cross-section. Combined with... Figure 2 as well as Figure 5 In this application, one end of the hot air chamber 103 wraps around the air outlet of the combustion chamber 101, and the other end of the hot air chamber 103 is connected to the water container chamber 102. An air supply chamber 106 is also provided between the other end of the hot air chamber 103 and the water container chamber 102. The air supply chamber 106 can be annular and is located around the periphery of the combustion chamber 101, and it is connected to the combustion chamber 101. The air supply chamber 106 is also provided to reduce the temperature of the hot air generated by the burner 2. In a specific implementation, the air supply chamber 106 and the combustion chamber 101 can be connected through at least one second air supply pipe 7, wherein one end of the second air supply pipe 7 is connected to the air supply chamber 106, and the other end is inserted into the combustion chamber 101.

[0057] Combination Figure 2 In some embodiments, multiple second air supply pipes 7 can be arranged circumferentially around the combustion chamber 101, and the other ends of multiple first air supply pipes 5 are axially arranged towards the air outlet end of the hot air chamber 103. Since the distance between the air supply chamber 106 and the burner 2 is relatively far, the air supplied through the multiple second air supply pipes 7 will not affect the normal operation of the burner 2, and can directly act on the hot air working in the burner 2 to facilitate the cooling of the hot air.

[0058] Combination Figure 5 In this application, a second air intake pipe 8 is provided on the outside of the main body 1. The second air intake pipe 8 is connected to the air supply cavity 106. A second air inlet 81 is provided at the outer end of the second air intake pipe 8 so as to deliver cold air to the combustion cavity 101 through the second air inlet 81, the second air intake pipe 8, the air supply cavity 106, and the second air supply pipe 7, so as to reduce the air temperature in the combustion cavity 101.

[0059] Combination Figure 2In some embodiments, the hot air cavity 103 is generally annular in shape, with a partition plate 107 inside. The partition plate 107 divides the hot air cavity 103 into a first cavity 108 and a second cavity 109. The first cavity 108 is located around the combustion cavity 101, and the second cavity 109 is located around the first cavity 108. The first cavity 108 and the second cavity 109 are connected. The washing machine also includes a hot air connector 11, which is connected to the end of the first cavity 108 away from the water container cavity 102. In specific implementation, air enters the second cavity 109 through the end away from the water container cavity 102, flows into the first cavity 108 through the second cavity 109, and while flowing in the first cavity 108, the air exchanges heat with the hot air in the combustion cavity 101 to heat the air in the first cavity 108, and is then led out through the hot air connector 11. The hot air connector 11 can be directly discharged into the atmosphere or introduced into a dryer to dry clothes, etc., without any restrictions.

[0060] In one embodiment, a plurality of ventilation holes may be provided on the partition plate 107 to connect the first cavity 108 and the second cavity 109, thereby improving the uniformity of air supply to the first cavity 108.

[0061] Combination Figure 2 In this application, a blower 9 and a third air intake pipe 10 are provided on the outside of the main body 1. The input end of the blower 9 is connected to the output end of the third air intake pipe 10, and the output end of the blower 9 is connected to the end of the second cavity 109 away from the water container cavity 102, so that air is delivered to the hot air cavity 103 through the third air intake pipe 10 by the blower 9, so as to exchange heat with the hot air in the combustion cavity 101, thereby reducing the air temperature in the combustion cavity 101.

[0062] This application, through the arrangement of the water reservoir 102, the first air supply pipe 5, the air supply chamber 106, the second air supply pipe 7, and the hot air chamber 103, can achieve four-stage cooling along the airflow direction within the combustion chamber 101, so that the hot air output from the outlet of the combustion chamber 101 meets the temperature required for ironing by the ironing machine. Specifically, the initial hot air temperature generated when the gas heater is working can be between 1400-1500℃, the hot water temperature in the water reservoir 102 can reach between 80-95℃, the hot air temperature output from the hot air connector 11 can be between 100-120℃, and the hot air temperature output from the outlet of the combustion chamber 101 is between 400-450℃, which fully meets the temperature requirements of the hot air for ironing by the ironing machine.

[0063] Combination Figure 2In this application, an exhaust fan 12 can be connected to the exhaust end of the combustion chamber 101. The exhaust fan 12 can be connected to the air inlet of the ironing machine through the exhaust connector 13, so as to guide the hot air output from the exhaust end of the combustion chamber 101 into the ironing machine through the exhaust fan 12.

[0064] In a second aspect, this application also provides a washing system. Figure 6 Schematic diagrams of the washing system in some embodiments are shown. (Combined with...) Figure 6 The washing system includes an ironing machine 14, a dryer 14, and the aforementioned washing oven. The ironing machine 14 is provided with a first air inlet, and the dryer 14 is provided with a second air inlet. The air outlet of the combustion chamber of the aforementioned washing oven is connected to the first air inlet of the ironing machine 14 to deliver hot air that meets the temperature requirements to the ironing machine 14. The hot air chamber of the washing oven is connected to the second air inlet of the dryer 14 to deliver hot air that meets the temperature requirements to the dryer 14.

[0065] The washing system provided in this application can simultaneously provide the heat required for the ironing machine 14 and the dryer 15 to work through the washing furnace, thereby reducing energy waste and having great practicality.

[0066] Combination Figure 6 The ironing machine 14 is also equipped with an air outlet, which is connected to the air outlet of the combustion chamber of the washing machine. This allows the hot air output by the ironing machine 14 after operation to be reintroduced into the air outlet of the combustion chamber for reuse, thereby reducing energy consumption. In a specific implementation, the washing system also includes a circulating fan 16, which introduces the hot air output by the ironing machine after operation into the air outlet of the combustion chamber for reuse.
