They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figures 1 to 5 As shown, the embodiment of the present invention provides a heat preservation steam cabinet capable of recovering waste heat of distilled water, comprising a steam cabinet body 1, a steam cabinet inner tank 2, a steam generating device 3, a steam delivery pipe 4 and a filter cover 5;

[0032] The steamer inner tank 2 is arranged inside the steamer body 1, and the steam generating device 3 is arranged on the side of the steamer body 1. The steam generating device 3 is connected to the steamer inner tank 2 through the steam conveying pipe 4. The steam generating device 3 is used to generate steam, and the steam conveying pipe 4 is used to discharge the steam to the steamer inner tank 2; food to be heated can be placed in the steamer inner tank 2. When the steam contacts the food in the steamer inner tank 2, it can transfer heat to the food to achieve the purpose of steaming or heating.

[0033] A water collecting trough 20 is provided at the bottom of the steam cabinet inner tank 2, and the water collecting trough 20 is used to collect the distilled water flowing out of the steam delivery pipe 4. A guide slope 21 is provided on the steam cabinet inner tank 2 at both ends of the water collecting trough 20, and the height of the guide slope 21 gradually decreases in the direction toward the water collecting trough 20; the setting of the guide slope 21 allows the distilled water dripping to the bottom of the steam cabinet inner tank 2 to flow along the guide slope 21 toward the water collecting trough 20. As the height of the guide slope 21 gradually decreases, the distilled water can automatically flow into the water collecting trough 20, thereby improving the collection efficiency of the distilled water; since the distilled water has a certain amount of waste heat, the distilled water is converged into the water collecting trough 20, which can achieve the insulation effect of the food on the steam cabinet inner tank 2 and improve the energy utilization rate of the steam cabinet.

[0034] The filter cover 5 is arranged above the water collection tank 20. The filter cover 5 is used to filter impurities entering the water collection tank 20. The water collection tank 20 is provided with a drainage hole 201. The drainage hole 201 is provided with a water plug 202. The water plug 202 is used to block the drainage hole 201. The filter cover 5 can filter impurities, such as food residues and particulate matter, that fall from the steamer inner tank 2 into the water collection tank 20, prevent impurities from entering the water collection tank 20, keep the distilled water clean, and reduce blockage or pollution of the drainage pipe. The water plug 202 can close the drainage hole 201 to control the discharge of distilled water, so that the distilled water is temporarily stored in the water collection tank 20, which is convenient for waste heat recovery and prolongs the heat preservation effect. When the waste heat of the distilled water is exhausted, the distilled water no longer has the heat preservation effect. At this time, the water plug 202 can be pulled out to discharge the distilled water in the water collection tank 20 through the drainage hole 201. It should be noted that a first drain pipe 203 is provided at the bottom of the drain hole 201 , and the first drain pipe 203 is used to drain the distilled water in the water collecting tank 20 .

[0035] like Figure 3 and Figure 5 As shown, the steam generating device 3 further includes a water tank 31, a heating pipe 32, and a temperature sensor 33. The heating pipe 32 is disposed within the water tank 31. A steam outlet is provided at the top of the water tank 31, which is connected to the steam delivery pipe 4. The heating pipe 32 is used to heat the water within the water tank 31, generating steam therein. The probe portion of the temperature sensor 33 extends into the water tank 31 to detect the heated temperature of the water within the water tank 31. The water tank 31 serves as a container for storing the water required for the heating process, allowing the steamer to continuously generate sufficient steam, avoiding interruptions in the steam supply, and maintaining uniform heating of food or items. The temperature sensor 33 monitors the temperature of the water within the water tank 31 in real time, ensuring that the water temperature remains within a set range during the heating process, avoiding prolonged operation of the heating pipe 32 and reducing energy waste.

[0036] like Figures 3 to 5As shown, further, the steam generating device 3 also includes a float valve 34 and a water inlet pump 35. The float valve 34 is provided in the water tank 31, and the water inlet pump 35 is provided at the side end of the water tank 31. The water inlet pump 35 is connected to the water inlet of the water tank 31 through a water pipe. The float valve 34 is used to control the opening or closing of the water inlet pump 35. The float valve 34 can detect the water level in the water tank 31. When the water level drops, the float valve 34 sinks accordingly and controls the water inlet pump 35 to start and replenish water; when the water level rises to the set value, the float valve 34 also rises and controls the water inlet pump 35 to stop running, so that the water level in the water tank 31 is always maintained within an appropriate range, eliminating the need for frequent manual water addition operations, which is practical and convenient.

[0037] like Figure 4 As shown, a second drain pipe 36 is further provided at the bottom of the water tank 31, and a solenoid valve 37 is provided on the second drain pipe 36 to control the opening and closing of the second drain pipe 36. During operation of the steam generating device 3, some sediment or scale will form in the water tank 31. Long-term accumulation can affect the efficiency and water quality of the steam cabinet. By providing the second drain pipe 36 and the solenoid valve 37, wastewater, sediment, or scale in the water tank 31 can be automatically and regularly drained, keeping the water tank 31 clean and preventing bacteria and harmful substances in the water from being transferred to the food surface through steam.

[0038] like Figure 4 As shown, the system further includes a three-way pipe 61 and a third drain pipe (not shown). The first end of the three-way pipe 61 is connected to the first drain pipe 203, the second end of the three-way pipe 61 is connected to the second drain pipe 36, and the third drain pipe is connected to the third end of the three-way pipe 61. Through the three-way pipe 61, wastewater from the sump 20 and the water tank 31 can be converged into the third drain pipe for unified discharge, reducing the number of pipes and saving space.

[0039] like Figure 3 As shown, a heat dissipation fan 7 is further included. The heat dissipation fan 7 is disposed within the steam cabinet body 1, with the air outlet of the heat dissipation fan 7 facing the steam generating device 3. Since the steam generating device 3 is disposed within the enclosed space of the steam cabinet body 1 and has limited heat dissipation performance, the heat dissipation fan 7 can blow air directly toward the steam generating device 3 to quickly remove heat, thereby improving the thermal circulation within the steam cabinet and enhancing the heat dissipation effect of the steam cabinet.

[0040] like Figure 3 As shown, further, a steam cabinet door 10 is provided on the steam cabinet body 1, and the steam cabinet door 10 is hingedly connected to the steam cabinet body 1. The steam cabinet door 10 is used to open or close the steam cabinet inner tank 2 to prevent steam and heat loss.

[0041] like Figure 1 and Figure 2 As shown, further, steaming plate hangers 22 are provided on both side walls of the steamer inner tank 2. In this embodiment, the steaming plate hangers 22 are multi-layered, so that the steamer inner tank 2 can accommodate multiple steaming plates at the same time, so as to make full use of the space inside the steamer, increase the capacity of the steamer, and enable users to steam more food in one operation, thereby improving the steaming efficiency.

[0042] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
