Technical Field
[0001] The utility model relates to the technical field of condensate collection, in particular to a condensate fitting for steam heating and a steam appliance. Background Art
[0002] Steamed bun machines, steam ovens, etc. are small household appliances used for making foods such as steamed buns and steamed dumplings. They generate steam by heating water with a heating element and use the high-temperature and high-pressure steam to steam the food. Their design is simple and easy to operate. Users only need to add water, put in the food and set the time, and they are applicable to various occasions such as families, tea restaurants, western restaurants, beverage stores, and Chinese restaurants.
[0003] Currently, taking a steamed bun machine as an example, when a commercially available steamed bun machine is in use, after the heating element heats the water body, the steam provides heat for the food, and the high-temperature steam steams the food. As the steam contacts the inner wall of the steam cavity, the steam will liquefy on the inner wall, thus forming high-temperature condensate. The condensate will hang on the inner wall of the steam cavity, and over time, the condensate will gradually flow down due to excessive accumulation. The condensate provides an environment for the growth of bacteria and molds; at the same time, it will also cause the internal environment of the steamed bun machine to become humid, affecting the electrical performance and service life of the steamed bun machine and the taste of the food. Therefore, the condensate needs to be discharged from the steam cavity in a timely manner.
[0004] With the use of the steamed bun machine, in order to ensure the discharge of condensate, it uses a straight groove method to collect the condensate. After the condensate is collected at the bottom of the steam cavity, it is directly discharged through a drain pipe for timely treatment of the condensate. However, this method still has deficiencies. The condensate flows down from the steam cavity, and the temperature of the steam cavity is very high. Therefore, the condensate absorbs a large amount of heat during the process of flowing down the wall of the steam cavity. When the condensate exits from the drain pipe, the condensate still has too high a temperature and is often accompanied by the emission of steam. The user needs to prepare, take and place various foods near the steamed bun machine, and it is extremely easy to cause the user to be scalded by the emitted steam, reducing the user experience. At the same time, the drain pipe will be deformed and leak liquid due to the high-temperature condensate.
[0005] Therefore, this application aims to reduce the temperature of the condensate discharged from the steam cavity, avoid the user being scalded by the steam emitted by the high-temperature condensate, and at the same time reduce the expansion of the drain pipe caused by the high-temperature condensate to prevent the drain pipe from leaking. Summary of the Utility Model
[0006] The main purpose of the utility model is to provide a solution to reduce the temperature of the condensate discharged from the steam cavity, avoid the user being scalded by the steam emitted by the high-temperature condensate, and at the same time reduce the expansion of the drain pipe caused by the high-temperature condensate to prevent the drain pipe from leaking.
[0007] To achieve the above object, the present utility model provides a condensation fitting for steam heating, comprising a steam cavity and a condensation member provided at the steam inlet of the steam cavity. It is characterized in that the condensation member comprises
[0008] a cooling seat having a diversion cavity with an opening facing the steam cavity; and
[0009] a drainage device communicating with the water outlet of the diversion cavity;
[0010] wherein, a flow retardation structure for reducing the flow rate of the condensed water is provided on the inner wall of the diversion cavity, and the condensed water flows in from the inner wall of the diversion cavity and flows out from the drainage device.
[0011] Furthermore, the inner wall of the diversion cavity is made of a heat-conducting material.
[0012] Furthermore, the diversion cavity is frustum-shaped with the opening of the diversion cavity as the base.
[0013] Furthermore, the flow retardation structure is a spiral diversion groove.
[0014] Furthermore, the flow retardation structure is a stepped diversion groove.
[0015] Furthermore, the cross-section of the diversion groove is arc-shaped.
[0016] Furthermore, the condensation member further comprises a guide plate installed at the opening end of the diversion cavity, and the guide plate receives the condensed water from the steam cavity and guides the condensed water to the inner wall of the opening of the diversion cavity.
[0017] Furthermore, a horizontal section is provided at the periphery of the opening end of the diversion cavity, and the horizontal section is used to receive the condensed water flowing from the guide plate to the diversion cavity.
[0018] The present application also discloses a steam appliance, comprising a steam heating condensation fitting as described above and a steam bun machine, a steam roasting machine, a heat exchanger, and a steam heater of the steam appliance.
[0019] Adopting the above technical solutions has the following advantages:
[0020] The present utility model uses a cooling seat to receive the condensed water from the steam cavity. The condensed water flows in from the inner wall of the opening of the steam cavity. The diversion cavity obstructs the condensed water, and the heat-conducting material accelerates the heat dissipation of the condensed water, so that the temperature of the condensed water is dissipated in time from the side wall of the diversion cavity. Thus, the temperature of the condensed water in the diversion cavity can be greatly reduced, avoiding the steam scalding caused by the high-temperature condensed water to the user, and at the same time reducing the expansion of the high-temperature condensed water to the drain pipe, so as to prevent the drain pipe from leaking.
[0021] The heat conduction cavity is arranged in a spiral or stepped manner to increase the travel distance of the condensed water flowing towards the drainage device, and the diversion cavity is arranged in a frustum shape, which can further increase the contact area between the condensed water and the diversion cavity, greatly improving the heat dissipation effect of the condensed water and ensuring the uniformity of the flow of the condensed water.

[0029] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below in conjunction with the drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present utility model and do not constitute a limitation to the present utility model.
[0030] As Figures 1-3 shown, a condensate fitting for steam heating includes a steam cavity 11, a base 13 that supports the steam cavity 11 and provides steam, and a condensate member 12 installed on the base 13. The condensate member 12 includes a cooling seat 124 and a drainage device 125. The cooling seat 124 has a diversion cavity 1242 with an opening facing the steam cavity 11; the drainage device 125 communicates with the water outlet of the diversion cavity 1242; wherein, the condensed water flows from the inner wall of the diversion cavity 1242 towards the drainage device 125, and a slow-flow structure that hinders the condensed water from flowing towards the drainage device 125 is provided on the inner wall of the diversion cavity 1242. When the diversion cavity 1242 hinders the condensed water, the temperature of the condensed water is dissipated in a timely manner from the side wall of the diversion cavity 1242, thereby greatly reducing the temperature of the condensed water in the diversion cavity 1242.
[0031] Specifically, the inner wall of the diversion cavity 1242 is made of a heat-conducting material, which accelerates the heat dissipation of the condensed water and further enhances the heat dissipation effect of the condensed water in the diversion cavity 1242. The base 13 is installed below the steam cavity 11 to ensure that the steam generated by the base 13 is sent into the steam cavity 11. A steam outlet 121 can be installed in the base 13, and the steam outlet 121 is arranged at one end of the base 13 close to the steam cavity 11, that is, at one end of the steam inlet of the steam cavity 11. The steam outlet 121 preferably adopts a nozzle method to accelerate the flow rate of the steam in the steam cavity 11; the drainage device 125 is connected to the water outlet of the condensed water in the diversion cavity 1242 through a pipeline, so that the condensed water in the diversion cavity 1242 can be discharged from the drainage device 125. The drainage device 125 can adopt a combination of a pipeline and a pump body, which can extract the condensed water accumulated in the diversion cavity 1242 and discharge it from the pipeline. Since the condensed water is cooled by the cooling seat 124, the steam emitted after the condensed water is discharged is greatly reduced, avoiding scalding the user due to the steam of the condensed water, and at the same time avoiding the situation of thermal expansion and contraction of the pipeline due to the condensed water, and further avoiding the possibility of pipeline rupture; the heat-conducting material can be a non-metallic material, such as heat-conducting plastic, and preferably a metal material, such as stainless steel, copper, or aluminum.
[0032] As Figures 3-5 shown, as a preferred embodiment of the present application, a horizontal section is provided at the periphery of the open end of the diversion cavity 1242, and this horizontal section is used to receive the condensed water flowing from the guide disk 122 to the diversion cavity 1242. Among them, the cooling seat 124 includes a seat body 1241, and the diversion cavity 1242 is opened on the seat body 1241, so that the condensed water can be collected from one end of the seat body 1241 and flow out from the other end. The horizontal section is arranged at the opening of the seat body 1241 close to the diversion cavity 1242. The water droplets in the steam cavity 11 first flow to the horizontal section of the seat body 1241, and after being collected in the horizontal section, they slowly flow to the inner wall of the diversion cavity 1242 from the opening of the diversion cavity 1242, keeping the condensed water flowing in from the inner wall of the diversion cavity 1242 to ensure that the slow-flow structure hinders the flowing speed of the condensed water and prolongs the flowing time of the condensed water in the diversion cavity 1242.
[0033] As the first embodiment of the present application:
[0034] As Figure 4 shown, the diversion cavity 1242 is frustum-shaped, and with the opening of the diversion cavity 1242 as the base, the slow-flow structure is a spiral diversion groove. When the condensed water on the horizontal section of the seat body 1241 flows to the opening of the diversion cavity 1242, the condensed water gradually flows along the spiral diversion groove along the edge of the base of the frustum. During this process, the condensed water in the diversion groove dissipates heat outward through the side wall of the seat body 1241, reducing the temperature of the condensed water, and finally flowing to the drainage device 125, and the drainage device 125 timely discharges the condensed water at the bottom end of the diversion cavity 1242.
[0035] As the second embodiment of the present application:
[0036] As Figure 5 shown, the diversion cavity 1242 is frustum-shaped, and with the opening of the diversion cavity 1242 as the base, the slow-flow structure is a stepped diversion groove. Multiple diversion grooves are arranged along the inner wall of the diversion cavity 1242. When the condensed water in the horizontal section of the seat body 1241 flows towards the opening of the diversion cavity 1242, it gradually flows along the inclined surface of the frustum from the edge of the base of the frustum to the first-layer diversion groove, causing the condensed water to accumulate in the first-layer diversion groove. The condensed water has sufficient residence time until the condensed water accumulated in the first-layer diversion groove is excessive. The condensed water overflowing from the first-layer diversion groove flows towards the second-layer diversion groove, and so on, flowing layer by layer towards the drainage device 125, increasing the residence time of the condensed water in the seat body 1241, thereby improving the cooling effect of the condensed water.
[0037] Based on the above two embodiments, the diversion cavity 1242 can be set to a cylindrical shape, so that the condensed water will flow along the diversion groove on the inner wall of the cylindrical shape towards the drainage device 125, but preferably the implementation methods of the two embodiments are adopted; based on the above two embodiments, the cross-section of the diversion groove can be arc-shaped to improve the smoothness of water flow. The arc part accommodates the condensed water, or a polygon with an opening can also be used. In the first embodiment, the condensed water flows along the cross-section of the polygon, and in the second embodiment, the condensed water is temporarily stored in the cross-section of the polygon and flows from the opening of the polygon towards the diversion groove of the subsequent polygon cross-section.
[0038] As Figure 2 shown, the condensing member 12 further includes a guiding disk 122 installed at the opening end of the diversion cavity 1242. The steam outlet 121 can be fixed on the guiding disk 122 by bolts. The guiding disk 122 receives the condensed water from the steam cavity 11 and guides the condensed water to the diversion cavity 1242. Among them, a sealing member 123 is further arranged between the guiding disk 122 and the diversion cavity 1242. The sealing member 123 includes but is not limited to rubber pads, polytetrafluoroethylene, silicone rubber, etc. The guiding disk 122 is provided with an inclined surface towards the opening of the diversion cavity 1242, so that the water droplets left by the steam cavity 11 gather on the guiding disk 122 and flow along the inclined surface of the guiding disk 122 towards the opening of the diversion cavity 1242.
[0039] A steam appliance, which includes a steam heating condensing fitting installed in a steam bun machine, a steam oven, a heat exchanger, and a steam heater. In these appliances, in order to reduce the influence of the discharged condensed water on the emitted steam, a fan can be arranged in the base 13 installed in the appliance, so that the fan discharges the heat at the cooling seat 124 outwards, further taking away the heat at the cooling seat 124 and maintaining the cooling effect of the condensed water.
[0040] During specific use, the steam outlet 121 sprays steam towards the inside of the steam cavity 11. The steam provides steam inside the steam cavity 11 and forms water droplets on the inner wall of the steam cavity 11. The water droplets gradually flow along the inner wall of the steam cavity 11 towards the guiding disc 122 and form condensed water. The guiding disc 122 gradually guides the condensed water to the horizontal section of the seat body 1241. The condensed water flows from the horizontal section of the seat body 1241 towards the opening of the diversion cavity 1242 and flows along the inner wall of the diversion cavity 1242. The inner wall of the diversion cavity 1242 hinders the flow of the condensed water, thereby increasing the residence time of the condensed water in the cooling seat 124 and further improving the heat dissipation effect of the cooling seat 124 on the condensed water until the condensed water flows to the drainage device 125, and the drainage device 125 discharges the cooled condensed water.
[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
