Description

Technical Field

[0001] The invention relates to a steamer. Background Art

[0002] As a common cooking appliance, a steamer cooks food with high-temperature steam during use, so a lot of heat is generated during the heating process; at the same time, the steamer also requires a high electrical power, so the electrical components of the steamer also generate a certain amount of heat. In the prior art, a fan is usually set to dissipate heat from the steamer to prevent the electrical components of the steamer from being damaged by overheating.

[0003] The steamer processes food ingredients through steam during use, so a water tank is required. Most water tanks now have a water inlet designed on the water tank cover. When the user takes the water tank to collect water, when there is a lot of water in the water tank, the water in the water tank is easy to overflow from the water tank during the movement, and the water will spill on the ground, causing the user to increase the cleaning work. There is also a solution to design a sealing ring on the water tank cover, but the user needs to manually remove the sealing cover to add water. There is water on the sealing cover, which will cause the user's hands to get wet, which is not conducive to user use. At the same time, the water tank is generally designed with a maximum water level. When the water in the water tank exceeds the maximum water level, the water in the water tank is easy to overflow, causing inconvenience. At the same time, the water tank is closed and fixed in the steamer, and is in a humid environment for a long time. It is generally difficult for users to ventilate and comb it. Long-term use is prone to breeding bacteria, affecting user use. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a steamer to overcome the defects in the prior art that the water tank of the steamer needs to be opened manually and ventilation is inconvenient.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A steam box, comprising a fan and a water tank assembly, wherein the water tank assembly comprises a water tank seat and a water tank body, wherein the fan has an air outlet and an air inlet, and the water tank body is movable relative to the water tank seat along the axial direction of the water tank seat;

[0007] The water tank assembly includes a conversion assembly, the conversion assembly includes a conversion member, the conversion member is provided with a fluid inlet, a fluid outlet and a communication port, the fluid inlet and the fluid outlet are respectively communicated with the communication port, and the communication port is communicated with the water tank seat;

[0008] The conversion assembly further includes a shielding member, the shielding member is movable relative to the fluid inlet and the fluid outlet, and the shielding member has a first shielding state and a second shielding state;

[0009] When the shielding member is in the first shielding state, the shielding member shields the fluid inlet, and the air outlet and the fluid outlet are connected to the communication port, so that the water tank body is retracted into the water tank seat;

[0010] When the shielding member is in the second shielding state, the shielding member shields the fluid outlet, and the air inlet end and the fluid inlet are connected with the connecting port, so that the water tank body extends out of the water tank seat.

[0011] In this solution, the fan is used to dissipate the heat generated by the steamer during use to prevent the electrical components of the steamer from being damaged due to excessive temperature. Under the rotation of the fan, the airflow flows from the air inlet end to the air outlet end of the fan. The water tank body is movable relative to the water tank seat along the axial direction of the water tank seat to extend or retract into the water tank seat. A space is enclosed between the side surface of the water tank body and the inner side wall of the water tank seat, and the connecting port is connected to the space, and the space is inflated or evacuated to increase or decrease the air pressure in the space so that the water tank body extends out or retracts the water tank seat. By setting a shielding member, when the shielding member is in a first shielding state, the fluid outlet is connected to the connecting port, the gas in the space is extracted through the fluid outlet, the gas pressure is reduced, and the water tank body is pushed into the water tank seat; when the shielding member is in a second shielding state, the fluid inlet is connected to the connecting port, the gas flows into the space through the fluid inlet, the gas pressure in the space is increased, and the water tank body is pushed out of the water tank seat. And in the process of switching the shielding member between the first shielding state and the second shielding state, the fan always rotates in one direction. Through the above arrangement, the water tank body can be pushed in and out in the horizontal direction, and the water in the water tank body is not easy to overflow during this process, which is beneficial to the use experience of the water tank assembly; at the same time, the fan set in the existing steamer is used to ensure that the fan cools the electrical components of the steamer, and the airflow generated by the fan is used to directly extend and retract the water tank body, which simplifies the structure of the steamer and facilitates the production of the steamer.

[0012] Preferably, the steamer includes an air guide plate, the air guide plate includes an opening and an air guide cavity, the fan is connected to the air guide plate, the air guide cavity connects the opening with the air inlet end or the air outlet end of the fan, the air guide plate is also provided with an exhaust port and an air inlet, the exhaust port is arranged on the side wall of the air guide cavity, the air inlet is arranged along the blowing direction of the fan, the exhaust port is connected to the fluid outlet through an exhaust pipe, and the air inlet is connected to the fluid inlet through an air inlet pipe.

[0013] In this solution, air enters the air guide cavity from the opening, and the air flow flows along the air guide cavity and the air inlet end of the fan toward the air outlet end through the rotation of the fan. An exhaust port and an air inlet are also provided on the air guide plate. The exhaust port is provided on the side wall of the air guide cavity, and the air inlet is provided along the blowing direction of the fan. The exhaust port is connected to the fluid outlet through the exhaust pipe, and the air inlet is connected to the fluid inlet through the air inlet pipe. Through the above arrangement, while ensuring that the fan can dissipate heat for the electrical components of the steamer, the fan can be used to extend and retract the water tank body, simplifying the structure of the steamer and facilitating the production of the steamer.

[0014] Preferably, the steamer comprises a steamer body, and in the width direction of the steamer body, the opening is arranged at a first end of the air guide plate, and the fan is arranged at a second end of the air guide plate.

[0015] In the present solution, through the above-mentioned arrangement, the air guide cavity of the air guide plate passes through the steamer body in the width direction of the steamer body, which is beneficial for the fan to dissipate heat from the electrical components of the steamer, thereby reducing the risk of damage caused by overheating of the electrical components of the steamer; in addition, the first end is the end where the steamer door of the steamer is opened, which can ensure communication with the outside air under various installation methods, thereby being beneficial to the air guiding effect of the air guide plate.

[0016] Preferably, the shielding member further has a third shielding state, and when the shielding member is in the third shielding state, the shielding member shields the fluid inlet and the fluid outlet.

[0017] In the present solution, when there is no need to change the extended or retracted state of the water tank body, the shielding member is in the third shielding state. At this time, air will not flow into or out of the space enclosed by the side surface of the water tank body and the inner wall of the water tank seat through the conversion assembly. The user can add water to the water tank body or the water tank body is in the water tank seat so that the steamer can be used normally.

[0019] In this solution, the space enclosed by the side surface of the water tank body and the inner side wall of the water tank seat is connected to the outside air through the pressure-stabilizing port, so that the air pressure in the space is equal to the atmospheric pressure. When the shielding member is in the first shielding state and the second shielding state, the shielding member shields the pressure-stabilizing port, and after the air flows into or out of the subsequent container through the fluid inlet or fluid outlet, the above-mentioned setting prevents the air pressure generated in the space from being restored through the pressure-stabilizing port, thereby ensuring that the fluid pressure in the subsequent container is adjusted through the conversion component, and then ensuring that the water tank body can be extended and retracted relative to the water tank seat, which is beneficial to the user experience of the steamer.

[0020] Preferably, when the shielding member is in the third shielding state, the communication port is communicated with the pressure-stabilizing port.

[0021] In this solution, when there is no need to adjust the fluid pressure in the space enclosed by the side surface of the water tank body and the inner side wall of the water tank seat, the shielding member is in the third shielding state, at which time the gas will not flow into or out of the subsequent container through the conversion assembly, and the above-mentioned setting makes the air pressure in the space enclosed by the side surface of the water tank body and the inner side wall of the water tank seat equal to the atmospheric pressure. Each time the shielding member is in the third shielding state, the air pressure in the space can be adjusted. When the shielding member switches from the third shielding state to the first shielding state or the second shielding state, the maximum or minimum fluid pressure in the space after adjustment can be stabilized, ensuring the safe use of the conversion assembly and the water tank assembly.

[0022] Preferably, the conversion member includes a box body, the fluid inlet, the fluid outlet and the pressure-stabilizing port are arranged on the same side wall of the box body, the conversion member also includes a rotating shaft, the shielding member is connected to the side wall of the box body through the rotating shaft, and the shielding member is rotatable around the rotating shaft.

[0023] In this solution, through the above-mentioned setting, it is convenient for the shielding member to shield the fluid inlet, fluid outlet and pressure-stabilizing port, simplifying the structural setting of the conversion component; the shielding member switches between the first shielding state, the second shielding state and the third shielding state by rotating, simplifying the structural setting of the conversion component and facilitating the use of the conversion component. When the fluid inlet and fluid outlet of the conversion component are connected to the air outlet and air inlet of the fan, the connection structure is simplified, facilitating the use of the conversion component.

[0024] Preferably, in the same straight line direction, the fluid inlet, the rotating axis and the fluid outlet are arranged in sequence, the line connecting the pressure-stabilizing port and the rotating axis is perpendicular to the line connecting the fluid inlet and the rotating axis, and the distances between the fluid inlet, the fluid outlet and the pressure-stabilizing port and the rotating axis are equal.

[0025] In this solution, through the above arrangement, the conversion assembly only needs to be provided with a single shielding member, and the switching between the first shielding state, the second shielding state and the third shielding state can be achieved by rotating the single shielding member. When the shielding member is in the third shielding state, it can be switched to the first shielding state or the second shielding state by rotating the shielding member clockwise or counterclockwise by the same angle, which simplifies the arrangement and operation of the conversion assembly, thereby facilitating the use of the conversion assembly.

[0026] Preferably, the water tank seat includes a accommodating cavity, the water tank body is arranged inside the accommodating cavity, a side surface of the water tank body and an inner wall of the accommodating cavity form a sealed space, and the communication port is connected to the sealed space.

[0027] In this solution, the water tank body is arranged in the accommodating cavity of the water tank seat, which can ensure the fixed position and stability of the water tank body. The water tank body can move in the accommodating cavity, which is convenient for operation and maintenance of the water tank body. One side surface of the water tank body forms a sealed space with the accommodating cavity, and the sealed space is connected with the connecting port. The airflow is formed by the rotation of the fan, and the air intake and exhaust of the sealed space are realized by the conversion component, and the air pressure inside the sealed space is adjusted, so that the water tank body extends or retracts relative to the water tank seat under the change of the air pressure in the sealed space. This structure realizes the automatic movement of the water tank body, does not require manual disassembly and assembly, is easy to operate, and ventilates the inside of the accommodating cavity when the gas enters and flows out of the sealed space, reducing the possibility of bacteria breeding.

The air intake and exhaust of the sealed space are realized through the conversion component to adjust the air pressure inside the sealed space. The other side of the baffle is connected to the water tank body, and the extension or retraction relative to the water tank seat is controlled by the movement of the baffle, which can facilitate the removal of the water tank body from the accommodating cavity and improve the sealing effect of the sealed space, so as to facilitate the adjustment of the air pressure in the sealed space by the rotation of the fan, and facilitate the use experience of the water tank assembly and the steamer.

The water tank body 22 is movable relative to the water tank seat 21 along the axial direction of the water tank seat 21 to extend or retract into the water tank seat 21. A space is enclosed between the side surface of the water tank body 22 and the inner side wall of the water tank seat 21, and the connecting port 3 is connected to the space, and the space is inflated or evacuated, and the air pressure in the space is increased or decreased to make the water tank body 22 extend or retract into the water tank seat 21. By setting the shielding member 4, when the shielding member 4 is in the first shielding state A, the fluid outlet 2 is connected with the communication port 3, the gas in the space is extracted through the fluid outlet 2, the gas pressure is reduced, and the water tank body 22 is pushed into the water tank seat 21; when the shielding member 4 is in the second shielding state B, the fluid inlet 1 is connected with the communication port 3, the gas flows into the space through the fluid inlet 1, the gas pressure in the space is increased, and the water tank body 22 is pushed out of the water tank seat 21.

[0087] In specific implementation, Figure 1 As shown, the steamer 100 includes an air guide plate 40, the air guide plate 40 includes an opening and an air guide cavity, the fan 30 is connected to the air guide plate 40, the air guide cavity is connected to the opening and the air inlet end or the air guide cavity is connected to the opening and the air inlet end, the air guide plate 40 is also provided with an exhaust port and an air inlet, the exhaust port is arranged on the side wall of the air guide cavity, the air inlet is arranged along the blowing direction of the fan 30, the exhaust port is connected to the fluid outlet 2 through the exhaust pipe 60, and the air inlet is connected to the fluid inlet 1 through the air inlet pipe 50.

[0088] The air enters the air guide cavity from the opening, and the air flow flows along the air guide cavity and the air inlet end of the fan 30 to the air outlet end through the rotation of the fan 30. The air guide plate 40 is also provided with an exhaust port and an air inlet, the exhaust port is arranged on the side wall of the air guide cavity, and the air inlet is arranged along the blowing direction of the fan 30. The exhaust port is connected to the fluid outlet 2 through the exhaust pipe 60, and the air inlet is connected to the fluid inlet 1 through the air inlet pipe 50. Through the above arrangement, while ensuring that the fan 30 can dissipate heat for the electrical components of the steam box 100, the fan 30 can be used to extend and retract the water tank body 22, simplifying the structure of the steam box 100 and facilitating the production of the steam box 100.

[0089] In specific implementation, Figure 1 As shown, the steamer 100 includes a steamer body. In the width direction of the steamer body, an opening is arranged at a first end of the air guide plate 40 , and the fan 30 is arranged at a second end of the air guide plate 40 .

[0090] Through the above-mentioned arrangement, the air guide cavity of the air guide plate 40 passes through the steamer body in the width direction of the steamer body, which is beneficial for the fan 30 to dissipate heat to the electrical components of the steamer 100, thereby reducing the direction in which the electrical components of the steamer 100 are damaged by overheating; in addition, the first end is the end at which the steamer door of the steamer 100 is opened, which can ensure communication with the outside air under various installation methods, thereby being beneficial to the air guiding effect of the air guide plate 40.

[0092] As a preferred implementation, Figure 6 As shown, the shielding member 4 also has a third shielding state C. When the shielding member 4 is in the third shielding state C, the shielding member 4 shields the fluid inlet 1 and the fluid outlet 2 .

When the shielding member 4 is in the first shielding state A and the second shielding state B, the shielding member 4 shields the pressure-stabilizing port 5. After the air flows into or out of the subsequent container through the fluid inlet 1 or the fluid outlet 2, the above-mentioned setting prevents the air pressure generated in the space from being restored through the pressure-stabilizing port 5, thereby ensuring that the fluid pressure in the subsequent container is adjusted through the conversion component 10, and then ensuring that the water tank body 22 can be extended and retracted relative to the water tank seat 21, which is beneficial to the user experience of the steamer 100.
