Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a steam heating device. Background Technology

[0002] As people's living standards improve, their demands for the nutrition and taste of food are also gradually increasing. Steaming food results in less nutrient loss and preserves the original flavor of the food, leading to the increasing popularity of steam heating devices in households. A typical steam heating device includes a cooking chamber for holding and heating the food, and a steam generator for supplying steam to the cooking chamber.

[0003] When using a steam heating device to heat food, water accumulates at the bottom of the cooking cavity due to steam condensation and the moisture contained in the food itself. This causes uneven heating and negatively impacts food hygiene. In related technologies, steam heating devices have a wastewater box installed below the cooking cavity, connected to the cavity, to collect wastewater. However, the drainage channel between the wastewater box and the cooking cavity is prone to blockage, preventing the wastewater from draining. Utility Model Content

[0004] In view of this, the present invention provides a steam heating device to solve the problem in the related art that the drainage channel between the wastewater box and the cooking cavity of the steam heating device is easily blocked, causing the wastewater in the cooking cavity to be unable to be discharged.

[0005] In a first aspect, this utility model provides a steam heating device, comprising:

[0006] The shell has a partition structure and a drainage channel inside. The partition structure can separate the cooking chamber and the wastewater chamber inside the shell. The cooking chamber can be opened and closed. The drainage channel is located on the partition structure and is used to connect the cooking chamber and the wastewater chamber. The wastewater chamber is used to collect the water accumulated in the cooking chamber.

[0007] The filter assembly is located inside the cooking cavity and is positioned to cover the inlet of the drain channel.

[0008] Beneficial effects: In use, the steam heating device of this utility model can supply steam to the cooking cavity, thereby heating the food in the cooking cavity.

[0009] During cooking, water formed due to steam condensation and moisture carried by the food itself can flow into the wastewater box through the drainage channel. This prevents water from remaining in the cooking cavity, which could cause uneven heating, poor cooking results, and bacterial growth, thus affecting food hygiene and the health of users.

[0010] Furthermore, during use, the water in the cooking chamber of the steam heating device of this utility model can be filtered by the filter component before flowing into the drainage channel, thereby avoiding blockage of the drainage channel and poor drainage.

[0011] Based on this, the cooking chamber is openable and closable, which not only makes it easy for the operator to put food into or take food out of the cooking chamber, but also makes it easy for the operator to open the cooking chamber and clean the filter component when it is dirty, so that the filter component can continue to filter water.

[0012] Therefore, the steam heating device of this utility model embodiment can not only avoid water accumulation in the cooking cavity, causing uneven heating and poor cooking effect, and prevent water accumulation in the cooking cavity from breeding bacteria, thus affecting food hygiene and user health, but also prevent drainage channels from being blocked, causing poor drainage. It can also make it easy for the operator to open the cooking cavity and clean the filter component when it is dirty, so that the filter component can continue to filter water.

[0013] In one alternative embodiment, a first connecting portion is formed on the filter assembly, and a second connecting portion is formed on the partition structure, wherein the first connecting portion is detachably connected to the second connecting portion.

[0014] Beneficial effects: With this setup, when the filter assembly needs cleaning, the operator can disconnect the connection between the first and second connecting parts, thereby removing the filter assembly from the cooking cavity, and thus easily and quickly cleaning the filter assembly by rinsing or brushing.

[0015] In one alternative embodiment, there are multiple drainage channels spaced apart on the partition structure, and the filter assembly is a filter screen covering the multiple drainage channels.

[0016] Beneficial effects: Multiple drainage channels can increase the speed and capacity of drainage, effectively reducing the risk of water accumulation. When one drainage channel has a problem (such as blockage or damage), the other drainage channels can continue to work, ensuring the overall stability of the drainage system.

[0017] In one alternative embodiment, the housing includes:

[0018] The main body of the shell has an opening formed on one side wall;

[0019] The pull-out box is slidably disposed inside the housing body through the opening, and the wastewater chamber is formed inside the pull-out box.

[0020] Beneficial effects: When the pull-out box is inserted into the main body of the housing, the cooking cavity is in the closed state. When the pull-out box is pulled out from the main body of the housing, the cooking cavity is in the open state.

[0021] In one alternative implementation, a guide structure is provided between the housing body and the pull-out box.

[0022] Beneficial effects: The guide structure can limit the running path of the pull-out box, which not only ensures that the pull-out box can move accurately along the predetermined path, but also reduces the friction between the pull-out box and the main body of the shell during the movement. It can also effectively control the movement of the pull-out box, reduce the vibration and shaking of the pull-out box during the movement, thereby avoiding the spillage of water inside the box during the pull-out process, which would bring additional cleaning burden to the user.

[0023] In one alternative implementation, the guide structure includes:

[0024] The rollers are located on either the pull-out box or the main body of the casing;

[0025] A guide rail extends along the direction of the opening and is located on the other of the pull-out and housing bodies, allowing rollers to roll along the guide rail.

[0026] Beneficial effects: The rollers can slide smoothly along the guide rail, reducing the resistance encountered during the pulling out of the drawer and effectively reducing the vibration and shaking of the drawer during movement.

[0027] In one optional embodiment, the steam heating device further includes:

[0028] A liquid level sensor, located inside the pull-out box, is used to detect the liquid level inside the pull-out box;

[0029] The drive mechanism is located inside the housing body, and the power output end is connected to the pull-out box;

[0030] The control device can control the drive mechanism to extend or retract the pull-out box into the main body of the housing based on the detection results of the liquid level sensor.

[0031] Beneficial effect: With this setting, when the liquid level sensor detects that the water level in the pull-out box is higher than the first preset water level, the control device can control the drive mechanism to push the pull-out box out of the housing body.

[0032] When the liquid level sensor detects that the water level in the pull-out box is lower than the second preset water level, the control device can control the drive mechanism to pull the pull-out box back into the main body of the shell, thereby improving the automation level of the pull-out box.

[0033] In one alternative embodiment, the steam heating device further includes a handle disposed on a pull-out box.

[0034] Beneficial effect: The operator can hold the handle, making it easy and quick to pull the drawer out or push it back onto the main body of the casing.

[0035] In one alternative embodiment, the wastewater chamber is located below the cooking chamber.

[0036] Beneficial effect: With this design, water in the cooking cavity can automatically flow into the cooking cavity through the drainage channel under the action of gravity.

[0037] In one alternative implementation, the steam heating device is an electric steamer. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0055] The following combination Figures 1 to 8 The following describes embodiments of the present invention.

[0056] According to an embodiment of the present invention, a steam heating device is provided, comprising a housing 1 and a filter assembly 2.

[0057] The housing 1 includes a partition structure and a drainage channel 103. The partition structure separates a cooking chamber 101 and a wastewater chamber 102 within the housing 1. The cooking chamber 101 is openable and closable. The drainage channel 103 is located on the partition structure and connects the cooking chamber 101 and the wastewater chamber 102. The wastewater chamber 102 collects water accumulated in the cooking chamber 101.

[0058] The filter assembly 2 is located inside the cooking cavity 101 and covers the inlet of the drain channel 103.

[0059] In use, the steam heating device of this utility model can supply steam to the cooking cavity 101 to heat the food inside the cooking cavity 101.

[0060] In an optional embodiment, exemplarily, the steam generator includes a water storage container, a heating element, and a water pump. When the steam generator is operating, the water pump draws water from the water storage container and passes it through the heating element. The water absorbs heat, turns into steam, and is discharged into the cooking chamber 101. The steam comes into contact with the food within the cooking chamber 101, thereby steaming or cooking the food. The generated steam rises and fills the entire pot cavity, cooking the food inside. Due to the high steam temperature, the food can be heated and cooked more quickly while preserving its nutrients.

[0061] After the water vapor comes into contact with the food, some of the water vapor releases heat and liquefies into liquid water. The liquid water flows to the bottom panel of the cooking cavity 101 under the action of gravity, and then flows into the wastewater cavity 102 through the filter assembly 2 and the drain channel 103 in sequence.

[0062] However, since the water often comes into contact with food before flowing onto the bottom panel of the cooking cavity 101, the water often carries food residue. This food residue can easily clog the drainage channel.

[0063] In the steam heating device of this application embodiment, during the cooking process, the water accumulated due to the condensation of steam and the moisture carried by the food itself can flow into the wastewater box through the drain channel 103, so as to avoid water remaining in the cooking cavity 101, causing uneven heating and poor cooking effect, and to prevent the water remaining in the cooking cavity 101 from breeding bacteria, which would affect food hygiene and the health of users.

[0064] Furthermore, during use, the water in the cooking chamber 101 of the steam heating device of this utility model can be filtered by the filter component 2 before flowing into the drain channel 103, thereby avoiding the drain channel 103 from being blocked and causing poor drainage.

[0065] Based on this, the cooking cavity 101 is openable and closable, which not only makes it convenient for the operator to put food into or take food out of the cooking cavity 101, but also makes it convenient for the operator to open the cooking cavity 101 and clean the filter assembly 2 when there is dirt on the filter assembly 2, so that the filter assembly 2 can continue to filter the accumulated water.

[0066] Therefore, the steam heating device of this utility model embodiment can not only avoid water accumulation in the cooking chamber 101, causing uneven heating and poor cooking effect, but also prevent bacteria from growing in the cooking chamber 101, which would affect food hygiene and user health. It can also prevent the drainage channel 103 from being blocked, causing poor drainage. Furthermore, it allows the operator to open the cooking chamber 101 and clean the filter component 2 when it is dirty, so that the filter component 2 can continue to filter water.

[0067] In one embodiment, the steam heating device further includes a steam generator.

[0068] In one embodiment, the housing 1 includes a housing body 104 and a pull-out box. A pull-out opening is provided on one side wall of the housing 1, and the pull-out box is slidably inserted through the pull-out opening.

[0069] The cooking cavity 101 is located inside the pull-out box. When the pull-out box is inserted into the housing body 104, the cooking cavity 101 is in the closed state. When the pull-out box is pulled out from the housing body 104, the cooking cavity 101 is in the open state.

[0070] As an alternative implementation, in one embodiment not shown in the accompanying drawings, a door is hinged to the housing 1, which can selectively open or close the cooking cavity 101.

[0071] In one embodiment, a first connecting portion is formed on the filter component 2, and a second connecting portion is formed on the partition structure, wherein the first connecting portion can be detachably connected to the second connecting portion.

[0072] With this configuration, when the filter assembly 2 needs to be cleaned, the operator can disconnect the connection between the first connecting part and the second connecting part, thereby removing the filter assembly 2 from the cooking cavity 101, and thus easily and quickly clean the filter assembly 2 by rinsing or brushing.

[0073] After cleaning, the operator can put the filter assembly 2 back into the cooking chamber 101 and connect the first connecting part to the second connecting part, thereby stably limiting the filter assembly 2 at the inlet of the drain channel 103.

[0074] The first connecting part and the second connecting part are preferably, but not limited to, snap-fit ​​components, riveting components, bolt connection components or magnetic components.

[0075] When the first connecting part and the second connecting part are snap-fit ​​components, one of the first connecting part and the second connecting part can be selected as a hook, and the other of the first connecting part and the second connecting part can be selected as a slot that can accommodate the hook.

[0076] When the first connecting part and the second connecting part are bolted connection assemblies, the first connecting part and the second connecting part are respectively the first connecting hole and the second connecting hole, and the bolt can pass through the first connecting hole and the second connecting hole in sequence to connect the filter assembly 2 and the partition structure.

[0077] As an alternative implementation, in one embodiment not shown in the accompanying drawings, the filter assembly 2 is fixedly disposed inside the cooking chamber 101. The operator opens the cooking chamber 101 when the steam heating device is powered off and uses a scrubbing tool to clean the filter assembly 2.

[0078] In one embodiment, there are multiple drainage channels 103, which are spaced apart on the partition structure, and the filter assembly 2 is a filter screen 202 covering the multiple drainage channels 103.

[0079] Multiple drainage channels 103 can increase the speed and capacity of drainage, effectively reducing the risk of water accumulation. When one drainage channel 103 has a problem (such as blockage or damage), the other drainage channels 103 can still continue to work, ensuring the overall stability of the drainage system.

[0080] In one embodiment, the filter component 2 includes a frame 201 and a filter screen 202 disposed within the frame.

[0081] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the number of drainage channels 103 may also be selected as one.

[0082] In one embodiment, the housing 1 includes a housing body 104 and a pull-out box 106.

[0083] An opening 105 is formed on one side wall of the housing body 104. A pull-out box 106 is slidably disposed inside the housing body 104 through the opening 105, and the wastewater chamber 102 is formed inside the pull-out box 106.

[0084] With this configuration, when the wastewater chamber 102 is full, the operator can pull out the pull-out box 106 from the housing body 104 to pour out the wastewater in the wastewater chamber 102.

[0085] The pull-out box 106 is preferably made of water-resistant and corrosion-resistant materials to improve the reliability and stability of the pull-out box 106 and help extend the service life of the steam heating device.

[0086] As an alternative implementation, in an embodiment not shown in the accompanying drawings, one side wall of the housing 1 may also be provided with an openable and closable cover. When the wastewater chamber 102 is full of water, the operator can move the entire steam heating device to the location for recycling wastewater (e.g., a sink or sewer) and then open the cover to complete the wastewater dumping.

[0087] In one embodiment, the structure of the pull-out box 106 can be adjusted and optimized according to different specifications and models of the steam heating device to meet the needs of various products.

[0088] As another alternative implementation, in another embodiment not shown in the accompanying drawings, the wastewater chamber 102 is connected to a sewer via a drain pipe, and the steam heating device further includes a water pump mounted on the drain pipe.

[0089] When the wastewater chamber 102 is full, the water pump can draw water from the wastewater chamber 102 and discharge it into the sewer, thereby completing the drainage of the wastewater chamber 102.

[0090] In one embodiment, a guide structure is provided between the housing body 104 and the pull-out box 106.

[0091] The guide structure can restrict the running path of the pull-out box 106, which not only ensures that the pull-out box 106 can move accurately along the predetermined path, but also reduces the friction between the pull-out box 106 and the housing body 104 during the movement. It can also effectively control the movement of the pull-out box 106, reduce the vibration and shaking of the pull-out box 106 during the movement, and thus prevent water from spilling out of the box during the pull-out process, thus causing additional cleaning burden to the user.

[0092] The roller is disposed on one of the pull-out box 106 and the housing body 104. A guide rail extends along the orientation direction of the opening 105 and is disposed on the other of the pull-out box and the housing body 104, and the roller is capable of rolling along the guide rail.

[0093] The rollers can slide smoothly along the guide rail, reducing the resistance encountered by the pull-out box 106 during the pulling process, and effectively reducing the vibration and shaking of the pull-out box 106 during the movement.

[0094] Among them, the rollers are preferably rubber rollers, which can play a certain role in vibration reduction, so that the pulling process of the pull-out box 106 is more stable and smooth.

[0095] In one embodiment, the steam heating device further includes a liquid level sensor 3, a drive mechanism 5, and a control device.

[0096] The liquid level sensor 3 is located inside the pull-out box 106 and is used to detect the liquid level inside the pull-out box 106. The drive mechanism 5 is located inside the housing body 104, and its power output end is connected to the pull-out box 106. The control device can control the drive mechanism 5 to drive the pull-out box 106 to extend or retract into the housing body 104 based on the detection result of the liquid level sensor 3.

[0097] With this configuration, when the liquid level sensor 3 detects that the water level in the pull-out box 106 is higher than the first preset water level, the control device can control the drive mechanism 5 to push the pull-out box 106 out of the housing body 104.

[0098] When the liquid level sensor 3 detects that the water level in the pull-out box 106 is lower than the second preset water level, the control device can control the drive mechanism 5 to pull the pull-out box 106 back into the housing body 104, thereby improving the automation level of the pull-out box 106.

[0099] The first preset water level can be selected as the water level when the pull-out box 106 is full. The second preset water level can be selected as the water level after the water in the pull-out box 106 is emptied. This enables the control device to push the pull-out box 106 out of the housing body 104 when the water in the pull-out box 106 is full, thereby achieving automatic drainage. When the water in the pull-out box 106 is emptied, the drive mechanism 5 automatically retracts the pull-out box 106 into the housing body 104.

[0100] In one embodiment, the pull-out box 106 may be provided with an arc-shaped slide rail 1061, and the power output end of the drive mechanism 5 is slidably connected to the arc-shaped slide rail 1061.

[0101] When the liquid level sensor 3 detects that the liquid level in the pull-out box 106 is higher than the first preset water level, the drive mechanism 5 can push the pull-out box 106 out of the housing body 104. Then, the pull-out box 106 can tilt forward under the gravity of the wastewater, thereby discharging the wastewater into the kitchen sink or sewer. During this process, the power output end of the drive mechanism 5 can slide along the arc-shaped slide rail 1061, thereby avoiding damage to the power output end of the drive mechanism 5 during the tilting of the pull-out box 106.

[0102] In one embodiment, such as Figure 7 and Figure 8 As shown, the shell body 104 is provided with an elastic support 4. The elastic support 4 is located at the opening 105 and abuts against the upper end of the pull-out box 106. When the water level in the pull-out box 106 is higher than the first preset water level, the weight of the water in the pull-out box 106 is greater, which can compress the elastic support 4 and cause the pull-out box 106 to tip over, thereby pouring out the wastewater in the pull-out box 106.

[0103] like Figure 8 As shown, when the wastewater in the pull-out box 106 is poured out, the weight of the pull-out box 106 is reduced, and the elastic support 4 can extend through its own elastic restoring force, thereby forcing the pull-out box 106 to return to a horizontal state. Then, the liquid level sensor 3 detects that the water level in the pull-out box 106 is lower than the second preset water level, and the power output end of the drive mechanism 5 can automatically retract and retract the pull-out box 106 into the housing body 104.

[0104] This setup improves the drainage efficiency and automation of the pull-out box 106, thus enhancing the user experience.

[0105] In a preferred embodiment, the elastic support 4 abuts against the pull-out box 106 via a locking post, and the pull-out box 106 is provided with a locking groove 1062 at one end for connecting to the power output end of the drive mechanism 5.

[0106] When the pull-out box 106 slides relative to the housing body 104, the locking bead 401 can be used to reduce the frictional resistance between the pull-out box 106 and the elastic support 4.

[0107] When the pull-out box 106 is pulled out from the opening 105, the locking bead 401 can be confined within the locking groove 1062, thereby limiting the end of the elastic support 4 on the pull-out box 106, ensuring that the elastic support 4 can reliably push the pull-out box 106 back to the horizontal state.

[0108] As a possible implementation, in an embodiment not shown in the accompanying drawings, such as Figure 7 As shown, the power output end of the drive mechanism 5 can be detachably connected to the pull-out box 106. When the pull-out box 106 extends out of the housing 1 under the drive of the drive mechanism 5, the user can separate the power output end of the drive mechanism 5 from the pull-out box 106, pour out the wastewater in the pull-out box 106, and then connect the power output end of the drive mechanism 5 back to the pull-out box 106. Then, the liquid level sensor 3 detects that the water level in the pull-out box 106 is lower than the second preset water level, and the drive mechanism 5 automatically controls the pull-out box 106 to retract back into the housing body 104.

[0109] The drive mechanism 5 can be selected as a device capable of outputting linear motion, such as a hydraulic cylinder, pneumatic cylinder, electric cylinder, or a combination of motor and gear rack, etc.

[0110] The control device may include programmable logic control components (such as PLC or CPU), memory, and electronic components connected to the programmable logic control components, which are well known to those skilled in the art and will not be described in detail here.

[0111] In one embodiment, the steam heating device further includes a handle disposed on the pull-out box 106.

[0112] The operator can hold the handle to easily and quickly pull out the pull-out box 106 or push it back onto the housing body 104.

[0113] In one embodiment, the bottom of the pull-out box 106 has an upwardly recessed groove, and the front side of the pull-out portion has a relief opening that communicates with the groove. The groove and the relief opening together form a handle, allowing the operator to extend their hand through the relief opening into the groove to pull the pull-out box 106 out of the housing body 104.

[0114] As an alternative implementation, in one embodiment not shown in the accompanying drawings, a handle is provided on the front wall of the pull-out box 106.

[0115] In one embodiment, the wastewater chamber 102 is located below the cooking chamber 101.

[0116] With this configuration, water in the cooking chamber 101 can automatically flow into the cooking chamber 101 through the drainage channel 103 under the action of gravity.

[0117] As an alternative implementation, the wastewater chamber 102 can also be located on one side of the cooking chamber 101. In this case, a water pump can also be installed in the wastewater chamber 102, and the input end of the water pump is connected to the drainage channel 103. The water accumulated in the cooking chamber 101 can flow into the wastewater chamber 102 under the drive of the water pump.

[0118] In one embodiment, the steam heating device is an electric steamer. As an alternative implementation, the steam heating device can also be other devices that use steam for heating, such as a steam oven.

[0119] In actual production, the size, shape, power and other parameters of the electric steamer can be adjusted and optimized according to different needs and application scenarios.

[0120] In one embodiment, the housing 1 of the steam heating device is further provided with a decorative shell, which can be used to enhance the aesthetics of the steam heating device.

[0121] In summary, the steam heating device of this application embodiment can not only prevent water from remaining in the cooking chamber 101, causing uneven heating and poor cooking effect, and prevent bacteria from growing in the cooking chamber 101, thus affecting food hygiene and user health, but also prevent the drainage channel 103 from being blocked, causing poor drainage. It can also make it easy for the operator to open the cooking chamber 101 and clean the filter component 2 when it is dirty, so that the filter component 2 can continue to filter water.

[0122] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope of protection claimed in this application.
