[0029] Reference Figure 1 , an embodiment of the present invention provides an integrated stove with a pressure relief device, including:

[0030] A stove body, including an air duct system 1 and a steam oven 2; the air duct system 1 is used for sucking and discharging flue gas; one side of the air duct system 1 facing the steam oven 2 is provided with a pressure relief guiding structure 3; the pressure relief guiding structure 3 includes a relative first open end and a second open end; the first open end faces the inside of the air duct system 1, and the second open end faces the steam oven 2;

[0031] A pressure relief device 4, including a pressure relief piece 41, a pressure relief pipe 42, and a spring assembly 43. Each spring 431 in the spring assembly 43 includes a first connection end and a second connection end; the first connection end is fixedly arranged inside the pressure relief pipe 42, and the second connection end is fixedly connected to the pressure relief piece 41; a spring guiding seat 432 is arranged outside the spring 431, and the guiding direction of the spring guiding seat 432 is consistent with the telescopic direction of the spring 431;

[0032] The pressure relief piece 41 cooperates with one end of the pressure relief pipe 42, and the pressure relief piece 41 is used to close or open the pressure relief pipe 42; the other end of the pressure relief pipe 42 is provided with a concave wall structure 421, and the pressure relief pipe 42 is fixedly connected to the inner liner of the steam oven 2 through the concave wall structure 421;

[0033] The pressure relief pipe 42 passes through the pressure relief guiding structure 3 through the second open end of the pressure relief guiding structure 3, so that one end of the pressure relief pipe 42 faces the inside of the air duct system 1.

[0034] Specifically, an integrated stove integrates devices such as a stove, a steam oven, and a disinfection cabinet. These devices require ventilation and exhaust of flue gas. The duct system 1 is located at the back of the integrated stove body, and the suction and discharge of flue gas are achieved through the suction device and discharge pipe inside the system. For the steam oven 2, when the pressure reaches a certain threshold during operation, pressure relief treatment is required to discharge steam. In the prior art, the common pressure relief device 4 of the steam oven 2 exhausts and relieves pressure outside the door, which is costly and complex to assemble. Or a pressure relief nozzle is connected to the negative pressure box 11 of the duct system 1 of the integrated stove through a pipe for pressure relief. However, due to the unreasonable structure of the pressure relief nozzle, the pressure relief timing is not easy to control, resulting in a slow heating rate, large water consumption, and poor steaming and baking effects. In the embodiment of the present invention, the pressure relief device 4 is improved, and at the same time, direct exhaust and pressure relief are carried out through the duct system 1. One end of the pressure relief device 4 is connected to the steam oven 2, and the other end is communicated with the duct system 1, so as to realize the discharge of the steam pressure in the steam oven 2 through the duct system 1.

[0035] Among them, referring to Figure 2 , the pressure relief device 4 includes a pressure relief piece 41, a pressure relief pipe 42, and a spring assembly 43. The pressure relief piece 41 is connected to one end of the pressure relief pipe 42 through the spring assembly 43. Since the pressure relief piece 41 will come into contact with water vapor, a material that is not easy to rust and has a relatively high hardness can be selected. For example, in one embodiment, stainless steel is used as the pressure relief piece 41. The size of the pressure relief piece 41 is matched with the opening size of one end of the pressure relief pipe 42 to ensure that the pressure relief device 4 does not relieve pressure when the pressure relief piece 41 is closed, thereby ensuring sufficient pressure and a fast heating rate in the steam oven 2. The spring assembly 43 includes multiple springs 431, which are used to open or close the pressure relief piece 41. The specific principle is as follows: when the pressure in the steam oven 2 is less than the elastic force of the spring 431, the spring 431 acts on the pressure relief piece 41, and the elastic force tightens the pressure relief piece 41 to make the pressure relief piece 41 close at one end of the pressure relief pipe 42. When the pressure in the steam oven 2 is greater than the elastic force of the spring 431, the steam pressure acts on the pressure relief piece 41, and the steam pressure pushes the pressure relief piece 41 open, so that one end of the pressure relief pipe 42 is in an open state, thereby relieving pressure.

[0036] In a possible implementation manner, the pressure relief device 4 further includes a pressure relief piece sealing ring 411. The pressure relief piece sealing ring 411 is sleeved on the periphery of the pressure relief piece 41, and the second connection end of the spring 431 is fixedly connected to the pressure relief piece sealing ring 411. Specifically, in the embodiment of the present invention, the pressure relief piece sealing ring 411 is selected as a rubber ring. Through the pressure relief piece sealing ring 411, the sealing state of the pressure relief piece 41 to the pressure relief pipe 42 can be further ensured, so that the heating rate inside the steam oven 2 is fast and the steaming and baking effect is good.

[0037] In an embodiment of the present invention, the spring assembly 43 includes four springs 431, which are symmetrically and uniformly distributed around the inner wall of the pressure relief pipe 42. The first connection end of the spring 431 is fixed to the inner wall of the pressure relief pipe 42. The connection between the inner wall of the pressure relief pipe 42 and the spring 431 can be set as a concave circular ring structure, so that there is a connection space between the pressure relief pipe 42 and the spring 431. In a possible implementation manner, a spring fixing seat 433 is further included. One end of the spring fixing seat 433 is fixed to the inner wall of the pressure relief pipe 42, and the other end of the spring fixing seat 433 is fixedly connected to the first connection end of the spring 431.

[0038] Specifically, the first connection end of the spring 431 is connected to the inner wall of the pressure relief pipe 42 through the spring fixing seat 433, and the second connection end of the spring 431 is fixedly connected to the pressure relief piece 41. In addition, during the process of the spring 431 expanding and contracting, in order to ensure that the spring 431 can accurately reset without deviation, in an embodiment of the present invention, a spring guide seat 432 is arranged outside the spring 431. The spring guide seat 432 surrounds the outside of the spring 431. The guiding direction of the spring guide seat 432 is consistent with the expansion and contraction direction of the spring 431, which plays a role of guiding and limiting the spring 431, so that the spring 431 can accurately reset without deviation along the spring guide seat 432 during the expansion and contraction process.

[0039] Furthermore, in a possible implementation manner, the length of each spring 431 in the spring assembly 43 is determined based on the preset pressure threshold of the steam oven 2.

[0040] Specifically, the preset pressure threshold of the steam oven 2 can be determined according to the working parameters of the steam oven 2. For example, in an embodiment, the preset pressure threshold of the steam oven 2 is 0.8 Mpa (8 kgf / cm 2 ). Taking this as the critical value, the elastic force of the spring 431 is determined, and based on the elastic force coefficient of different springs, the length of the spring 431 is determined. When the pressure in the steam oven 2 does not reach the preset pressure threshold, the elastic force is greater than the steam pressure, and the spring 431 acts on the pressure relief piece 41 to make the pressure relief device 4 in a closed state, and the steam oven 2 is sealed, and continues to heat up and work to steam and bake food to ensure a good steaming and baking effect; when the pressure in the steam oven 2 reaches the preset pressure threshold, the elastic force is less than the steam pressure, and the steam pressure pushes the pressure relief piece 41 open, so that the pressure relief device 4 is in an open state, and the steam oven 2 relieves pressure through the pressure relief device 4.

[0041] The other end of the pressure relief pipe 42 is provided with a concave wall structure 421, and the concave wall structure 421 is cooperatively arranged with the inner liner of the steam oven 2 for connecting the pressure relief pipe 42 to the steam oven 2. In terms of the connection method, in a possible implementation manner, refer to Figure 3, the pressure relief device 4 further includes a pressure relief pipe sealing ring 422, the pressure relief pipe sealing ring 422 is sleeved on the concave wall structure 421 of the pressure relief pipe 42, and the concave wall structure 421 is pneumatically riveted to the inner liner of the steam oven 2 through the pressure relief pipe sealing ring 422.

[0042] The pressure relief device 4 is connected to the air duct system 1 through a pressure relief guiding structure 3. In a possible implementation manner, the opening area of the first open end of the pressure relief guiding structure 3 is larger than the opening area of the second open end; a clamping groove 31 is provided in the middle of the outer side of the pressure relief guiding structure 3. Specifically, it can be understood that the pressure relief guiding structure 3 is an overall micro-flared structure, and the first open end facing the pressure relief pipe 42 has a larger area than the second open end facing the air duct system 1. When the steam oven 2 is installed, it is directly pushed in, and the pressure relief pipe 42 passes through the pressure relief guiding structure 3 and is combined with the air duct system 1.

[0043] In a possible implementation manner, the air duct system 1 includes a negative pressure box 11, and an open end is provided on one side of the negative pressure box 11. The pressure relief guiding structure 3 is clamped to the open end of the negative pressure box 11 through the clamping groove 31, so that the first open end of the pressure relief guiding structure 3 faces the inner cavity of the negative pressure box 11.

[0044] Specifically, the clamping groove 31 of the pressure relief guiding structure 3 is arranged in cooperation with the open end of the negative pressure box 11, so that the pressure relief guiding structure 3 is clamped on the negative pressure box 11. In this way, the pressure relief pipe 42 passes through the pressure relief guiding structure 3, so that one end of the pressure relief pipe 42 faces the inner cavity of the negative pressure box 11. When the pressure relief piece 41 is in an open state, the pressure generated by the steam in the steam oven 2 and the suction force of the air duct system 1 are used to form pressure relief of the steam oven 2. The steam pressure in the steam oven 2 is directly discharged to the negative pressure box 11 through the pressure relief pipe 42 and discharged through the air duct system 1. The structure is simple and the installation is convenient.

[0045] In a possible implementation manner, the integrated stove further includes a frame bracket 5, which is arranged at the bottom of the stove body. The frame bracket 5 is connected to the air duct system 1, and a slide rail structure is provided between the frame bracket 5 and the steam oven 2. The slide rail structure is used for sliding limit during the process of the steam oven 2 entering the stove body.

[0046] Specifically, the frame bracket 5 is fixedly arranged at the bottom of the stove body. When installing the steam oven 2, the steam oven 2 is gently pushed into the integrated stove body through the slide rail structure on the frame bracket 5 and is engaged with the air duct system 1. The pressure relief device 4 on the steam oven 2 is installed by a push-pull combination, which is more convenient for production and maintenance.

[0047] Reference Figure 4, in a possible implementation, it further includes a solenoid valve 6 and a cabinet door 7. The solenoid valve 6 is arranged below the control panel of the integrated stove. Grooves 71 are respectively arranged at both ends of the upper end cover of the cabinet door 7, and the grooves 71 are used to cooperate with the solenoid valve 6 for locking.

[0048] Specifically, a solenoid valve 6 is arranged below the control panel of the integrated stove. When closing the cabinet door 7 of the steam oven 2, the solenoid valve 6 is buckled in the groove 71 of the cabinet door 7. When the steam oven 2 is working, the solenoid valve 6 acts to seal the cabinet door 7 and the inner liner of the steam oven 2, so as to prevent the pressure from pushing open the cabinet door 7 when the pressure in the steam oven 2 is too high. And the cooperation between the solenoid valve 6 and the groove 71 further ensures the sealing of the steam oven 2, and good working effects can be achieved both during operation and pressure relief.

[0049] In a possible implementation, a steam generator 21 is arranged at the bottom of the steam oven 2; the steam generator 21 is used to generate high-temperature water vapor to heat the interior of the steam oven 2.

[0050] On the other hand, the embodiments of the present invention introduce the working principle of the above-mentioned integrated stove with a pressure relief device 4, specifically as follows:

[0051] Preparation stage: Rivet the pressure relief device 4 to the inner liner air pressure of the steam oven 2 through the pressure relief pipe sealing ring 422 of the steam oven 2 (at this time, the pressure relief piece 41 and the pressure relief pipe 42 are in a closed state). Gently push the steam oven 2 into the integrated stove body through the frame bracket 5, so that the pressure relief device 4 is engaged with the negative pressure box 11. Set the working time T and working temperature Q of the steam oven 2, close the cabinet door 7, and the solenoid valve 6 cooperates with the groove 71 for locking.

[0052] Heating stage: The controller controls the water pump to supply water to the steam generator 21, and the two groups of heating pipes A and B on the steam generator 21 work simultaneously. The elastic force of the spring 431 > the steam pressure, and the pressure relief device 4 is in a sealed state.

[0053] Constant temperature stage: When the temperature detection device detects that the temperature of the inner liner of the steam oven 2 reaches Q, the steam pressure > the elastic force of the spring 431, and the steam pressure pushes open the pressure relief piece 41, and the pressure relief device 4 is in an open state. At the same time, control the B heating pipe on the steam generator 21 to work; when the temperature detection device detects that the temperature of the inner liner of the steam oven 2 is less than Q, the elastic force of the spring 431 > the steam pressure, the spring 431 acts on the pressure relief piece 41, and the pressure relief device 4 is in a sealed state, and control the A and B heating pipes on the steam generator 21 to work simultaneously. The above cycle works.

[0054] End stage: When the working time T counts down to 60 s, the controller controls the A and B heating tubes on the steam generator 21 to stop working; when the elastic force of the spring 431 > the steam pressure and the temperature detection device detects that the temperature inside the inner cavity of the steam oven 2 is lower than the working temperature Q, the solenoid valve 6 is opened to end the steaming and baking work.

[0055] In summary, for the integrated range hood with a pressure relief device of the present invention, the pressure relief piece is connected to the inner wall of the pressure relief pipe through a spring, and the pressure relief pipe is pneumatically riveted to the air pressure in the inner cavity of the steam oven. The pressure relief device has a simple structure; when the steam oven is installed, it is gently pushed into the integrated range hood body through the slide rail structure on the frame bracket. The pressure relief device is combined with the air duct system through the pressure relief guiding structure on the negative pressure box, and the pressure relief of the steam oven is completed by using the pressure generated by the steam in the steam oven and the suction force of the air duct system. The steam pressure in the steam oven is directly discharged to the negative pressure box through the pressure relief pipe and then discharged through the air duct system, with a simple structure and convenient installation.

[0056] It should be noted that the pressure relief device of the present invention is applicable to all steam boxes and steam baking integrated models, and all belong to the protection scope of the present invention.
