[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0043] Please see Figure 1-5 The embodiments provided by this utility model are as follows:
[0044] like Figure 1-2As shown, the trough-type ironing machine with circulating heat transfer oil includes a trough-type ironing machine body for ironing linens. The trough-type ironing machine body includes a frame 1 and rollers 2. Multiple sets of rollers 2 for transporting linens rotate on the frame 1. Ironing grooves are fixedly installed inside the frame 1 along the bottom sidewalls of the multiple sets of rollers 2. The ironing grooves located at the gaps between the multiple sets of rollers 2 are connected by transition grooves 8. Thus, a gap is formed between the rotating rollers 2 and the ironing grooves and transition grooves 8 for the linens to pass through. After the linens to be ironed are guided into the gap between the rollers 2 on one side of the trough-type ironing machine body and the ironing grooves and transition grooves 8, the linens to be ironed are transported on the ironing grooves and transition grooves 8 under the drive of the rotating rollers 2. During the transport process, the linens are heated and ironed, thereby achieving the function of ironing linens.
[0045] It is worth noting that multiple temperature sensing probes are installed near the bottom of the scalding tank and the transition tank 8. These probes detect the temperature of the scalding tank and the transition tank 8 in different areas to obtain the temperature of the hot oil, thereby controlling the temperature of the hot oil heated by the hot oil device 3.
[0046] like Figure 3 As shown, in order to enable the ironing tank and transition tank 8 to continuously provide high temperature for heating the linens, a hot oil device 3 for heating heat-conducting oil is installed on one side of the frame 1. The oil outlet of the hot oil device 3 is connected to the oil guide pipe, the oil outlet of the oil guide pipe is connected to the oil inlet on one side of the bottom of the ironing tank, and the oil outlet on the other side of the ironing tank is connected to the oil inlet inside the transition tank 8 through the connecting pipe 9.
[0047] The oil inlet of the hot oil device 3 is connected to the oil outlet of the oil pump 4, the oil inlet of the oil pump 4 is connected to the oil outlet of the return oil pipeline, and the oil inlet of the return oil pipeline is connected to the oil outlet inside the transition groove 8.
[0048] Among them, the transition groove 8 is a sealed arc-shaped plate with an internal cavity, and the hot trough also has an internal cavity.
[0049] The hot oil device 3 introduces heated heat-conducting oil into each ironing tank through the oil guide pipe. After the hot oil fills the inner cavity of the ironing tank, the surface temperature of the ironing tank rises to heat the linens passing through it. After passing through the ironing tank, the hot oil enters the cavity of the transition tank 8 through the connecting pipe 9, thus also heating the transition tank 8. After absorbing the temperature of the linens, the hot oil temperature drops and is then pumped by the oil pump 4, flowing back into the return oil pipe through the transition tank 8. Finally, it is reintroduced into the hot oil device 3 for reheating and then reintroduced into the ironing tank and transition tank 8, thus forming a hot oil circulation system to provide continuous heating for the linens.
[0050] Specifically, an oil outlet pipe 31 is fixedly installed at the bottom oil outlet end of the hot oil device 3. The oil outlet pipe 31 is connected to the oil inlet end of the oil guide pipeline. The oil guide pipeline includes a main oil guide pipe 5 and branch oil guide pipes 51. Branch oil guide pipes 51 are connected to the side wall of the main oil guide pipe 5 according to the location of the hot oil bath. The heated oil enters the main oil guide pipe 5 through the oil outlet pipe 31, and then is introduced into each branch oil guide pipe through the main oil guide pipe 5, and finally enters the hot oil bath, thus providing hot oil for the hot oil bath.
[0051] It is worth noting that, such as Figure 4 As shown, the hot water tank includes a flexible tank 7, the interior of which is a sealed cavity. The bottom surface of the flexible tank 7 is connected to the first oil inlet main pipe 73 and the first oil outlet main pipe 71 on both sides via the first curved pipe 72. The first oil inlet main pipe 73 is connected to the oil guide branch pipe 51, and the first oil outlet main pipe 71 is connected to the oil inlet end inside the transition tank 8 via the connecting pipe 9.
[0052] The flexible groove 7 has relatively low hardness and high thermal conductivity, which can iron thinner linens. The oil path is introduced from one side of the flexible groove 7 and then discharged from the other side of the flexible groove 7.
[0053] It is worth noting that, such as Figure 5 As shown, the hot water tank includes a rigid tank 10, the interior of which is a sealed cavity. Multiple supporting sheet metal parts are fixedly connected to the bottom surface of the rigid tank 10. The bottom of the rigid tank 10 is provided with a first oil outlet main pipe 71 and a first oil inlet main pipe 73. The two sides of the first oil inlet main pipe 73 are respectively connected to one end of the diversion pipe 74. The other end of the diversion pipe 74 is connected to the oil inlets on both sides of the bottom surface of the rigid tank 10. The two sides of the side wall of the first oil outlet main pipe 71 are respectively connected to one end of the return pipe 75. The other end of the return pipe 75 is respectively connected to the oil outlets on both sides of the bottom of the rigid tank 10. The first oil inlet main pipe 73 is respectively connected to the oil guide branch pipe 51. The first oil outlet main pipe 71 is connected to the oil inlet end inside the transition tank 8 through the connecting pipe 9.
[0054] The rigid groove 10 has relatively high hardness, which can iron thicker linens. The oil flow direction is that the oil flows into the distribution pipe 74 through the first oil inlet main pipe 73, and flows into the inner cavity from both sides of the rigid groove 10. Then, it flows out from the bottom of the rigid groove 10 through the return pipe 75, thereby accelerating the heating efficiency of the rigid groove 10.
[0055] In order to fully heat the linens, the inner side walls of the transition trough 8 are connected to the second oil inlet main pipe 81 and the second oil outlet main pipe 82 through the second curved pipe 83, respectively. The oil inlet end of the second oil inlet main pipe 81 is connected to the oil outlet end of the connecting pipe 9, and the oil outlet end of the second oil outlet main pipe 82 is connected to the oil inlet end of the return oil main pipe 6. The return oil main pipe 6 includes a return oil main pipe 6 and a return oil branch pipe 61. One end of the return oil branch pipe 61 is connected to the second oil outlet main pipe 82 in the transition trough 8, and the other end of the return oil branch pipe 61 is connected to the side wall of the return oil main pipe 6. The oil outlet end of the return oil main pipe 6 is connected to the oil inlet end of the oil pump 4, and the oil outlet end of the oil pump 4 is connected to the oil inlet pipe 32 at the top of the side wall of the hot oil device 3.
[0056] Although the temperature of the hot oil flowing out of the flexible groove 7 or the rigid groove 10 drops to some extent, the residual temperature is still higher. It is then introduced back into the inner cavity of the transition groove 8 through the connecting pipe 9 and the second oil inlet pipe 81 to continuously provide temperature to the linens transported by each roller, so as to prevent the linens from cooling down and causing a decrease in ironing effect.
[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
