Description

Technical Field

[0001] This application relates to the field of gas-fired steam cabinet technology, and in particular to a safe and environmentally friendly gas-fired steam cabinet. Background Technology

[0002] A steamer is a kitchen appliance that uses steam to heat food. It heats food by placing it inside the cabinet and then introducing high-temperature steam into the cabinet. It is widely used in large kitchens such as hotels, schools, and factories. Steamers are generally divided into electric steamers and gas steamers based on the different ways they generate high-temperature steam.

[0003] Existing gas-fired steam cabinets typically include a cabinet body, a hinged door that covers the cabinet body, a shelf that slides into the cabinet's interior, a water tank fixed to the bottom of the cabinet body, and a heating device fixed to the bottom of the cabinet body and located below the water tank. The water tank is connected to an external water supply pipe, and a float-type automatic water inlet valve is installed at the connection point to automatically add water for evaporation to the water tank. In use, the food to be heated is placed on the shelf and the cabinet door is closed. The heating device is then activated to heat the water stored in the water tank to boiling point, generating steam. The steam flows upwards within the cabinet's interior and comes into contact with the food, thus heating it.

[0004] Under normal circumstances, the float-type water inlet valve can automatically add evaporation water to the storage tank. However, if the water supply pipe is unable to add evaporation water to the storage tank due to water outage / insufficient water pressure, and this is not detected in time, it can easily lead to the storage tank running dry. This can damage the gas steamer or even cause a fire, indicating that the gas steamer is not safe enough. Therefore, further improvements can be made. Utility Model Content

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a safe and environmentally friendly gas-fired steam cabinet.

[0021] Reference Figure 1-3 The safe and environmentally friendly gas-fired steam cabinet includes a steam cabinet module 1, a burner module 2, a water supply module 3, and a water replenishment module 4. Specifically, the steam cabinet module 1 includes a cabinet body 11, a cabinet door 12 hinged to the cabinet body 11, and a shelf 13 slidably mounted on the cabinet body 11. The burner module 2 specifically includes a water storage tank 21 fixedly mounted at the bottom of the cabinet body 11 and a gas-fired heater 22 fixedly mounted at the bottom of the water storage tank 21. The water supply module 3 specifically includes a water supply pipe 31 connected to the water storage tank 21 and an automatic water inlet valve 32 fixedly mounted on the water supply pipe 31. The automatic water inlet valve 32 is a float-type automatic water inlet valve 32, which is located inside the water storage tank 21.

[0022] The specific structural design and implementation principle of the steam cabinet module 1 and the water supply module 3 described above are existing technologies and will not be repeated here.

[0023] The main function of the water replenishment module 4 is to add emergency water for evaporation to the water storage tank 21 when the water supply pipe 31 is unable to add water for evaporation due to water outage / insufficient water pressure, so as to avoid the water storage tank 21 from running dry for a certain period of time.

[0024] In this embodiment, the water replenishment module 4 specifically includes a storage component 41, a detection component 42, a conveying component 43, a control component 44, and an alarm component 45. The storage component 41 is a storage tank, fixedly installed at the bottom of the cabinet 11 and located below the water storage tank 21, used to hold emergency evaporation water. The detection component 42 is a water level sensor, fixedly installed inside the water storage tank 21, used to detect the remaining amount of evaporation water in the water storage tank 21, and generates a signal output when the remaining amount of evaporation water is lower or higher than a preset value. The conveying component 43 specifically includes a conveying pump 431 and a conveying pipe 432. The conveying pump 431 is a water pump, fixedly installed inside the storage component 41, and one end of the conveying pipe 432 is connected to the conveying pump 431, while the other end of the conveying pipe 432... The end is connected to the water storage tank 21, so that the emergency evaporation water loaded in the storage component 41 can be transported into the water storage tank 21 through the conveying component 43; the control component 44 is a PLC controller, and the control component 44 is electrically connected to the detection component 42 through a preset wire to receive the signal output by the detection component 42. In addition, the control component 44 is also electrically connected to the conveying component 43 through a preset wire to control the start and stop of the conveying component 43; the alarm component 45 specifically includes a buzzer 451 and an indicator light 452. The buzzer 451 and the indicator light 452 are both fixedly installed on the top of the cabinet 11, and the buzzer 451 and the indicator light 452 are electrically connected to the control component 44 through a preset wire, so that the control component 44 can control the buzzer 451 and the indicator light 452 to emit alarm signals as needed.

[0025] When the water supply pipe 31 is unable to add evaporation water to the water storage tank 21 due to water outage / insufficient water pressure, the evaporation water in the water storage tank 21 will continuously evaporate and decrease until the remaining amount of evaporation water in the water storage tank 21 is lower than the preset value. At this point, the detection component 42 will send a signal to the control component 44. The control component 44 will control the delivery component 43 to deliver the emergency evaporation water loaded in the storage component 41 to the water storage tank 21 until the remaining amount of evaporation water in the water storage tank 21 is higher than the preset value. On the other hand, the control component 44 will control the alarm component 45 to issue an alarm signal to remind the operator to repair the water supply pipe 31 or shut down the gas steamer in time, thereby improving the safety of the gas steamer.

[0026] It is worth mentioning that, in actual use, since the food is in the steam cabinet module 1 and the gas steam cabinet cannot be turned off immediately, the emergency evaporation water loaded in the storage component 41 is sent to the water storage tank 21, which can continue to maintain the heating of the food for a certain period of time.

[0027] In this embodiment, the water replenishment module 4 also includes a preheating component 46, which is an electric heating rod. The preheating component 46 is fixedly installed inside the delivery pipe 432, and the preheating component 46 is also electrically connected to the control component 44 via a preset wire. During the process of the delivery component 43 delivering the emergency evaporation water loaded in the storage component 41 to the water storage tank 21, the control component 44 will also activate the preheating component 46 to preheat the evaporation water, so as to avoid the water temperature being too low and affecting the steam output of the steam module.

[0028] In this embodiment, the conveying pipe 432 has a spiral structure. The spiral structure can extend the overall length of the conveying pipe 432, so that the preheating component 46 has enough space to set multiple sets along the extension direction of the conveying pipe 432, thereby more effectively preheating the evaporation water.

[0029] In this embodiment, the water replenishment module 4 further includes a water replenishment component 47, which includes a water replenishment pipe and an automatic water replenishment valve. One end of the water replenishment pipe is connected to the storage component 41, and the other end is connected to the water supply pipe 31. The automatic water replenishment valve is also a float-type automatic water replenishment valve, which is connected to the connection between the water replenishment pipe and the storage component 41. When the water supply pipe 31 resumes water supply, the evaporated water can enter the storage component 41 through the water replenishment component 47 for subsequent use.

[0030] In this embodiment, there are three sets of cabinet doors 12, and the three sets of cabinet doors 12 are arranged vertically. Since the steam is concentrated at the top, by opening the top cabinet door 12 first to let the steam out, and then opening the other cabinet doors 12 to take the food out, the risk of steam burns is minimized, thus improving safety.

[0031] Implementation principle: When the water supply pipe 31 is unable to add evaporation water to the water storage tank 21 due to water outage / insufficient water pressure, the evaporation water in the water storage tank 21 will continuously evaporate and decrease until the remaining amount of evaporation water in the water storage tank 21 is lower than the preset value. At this point, the detection component 42 will send a signal to the control component 44. The control component 44 will control the delivery component 43 to deliver the emergency evaporation water loaded in the storage component 41 to the water storage tank 21 until the remaining amount of evaporation water in the water storage tank 21 is higher than the preset value. On the other hand, the control component 44 will control the alarm component 45 to issue an alarm signal to remind the operator to repair the water supply pipe 31 or shut down the gas steamer in time, thereby improving the safety of the gas steamer.

[0032] The embodiments described herein are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
