Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a double-pot household electric rice cooker. Background Art

[0002] An electric rice cooker is a modern cooking appliance capable of steaming, boiling, stewing, simmering, and braising food. It not only cooks food well but also keeps it warm. While current electric rice cookers come in a wide variety of styles, most have very limited functionality. Traditional electric rice cookers can only steam one dish at a time while cooking rice or porridge, and cannot simultaneously steam steamed buns or dumplings. This is because the dryer compartment of traditional electric rice cookers is too close to the food. As the rice cooker heats, steam rushes upward, overheating the upper dryer compartment and damaging the steamed food. This problem is addressed in the dual-boiler electric rice cooker of the present invention. Summary of the Invention

[0003] In order to solve the above problems in the prior art, the present invention aims to provide a double-boiler household electric rice cooker.

[0004] The technical solution adopted in the present invention is:

[0005] A double-tank household electric rice cooker comprises an electric rice cooker body, a cover body adapted to fit the electric rice cooker body, an inner tank disposed within the electric rice cooker body, and a heating plate disposed below the inner tank. The electric rice cooker body comprises two parallel inner tanks, each of which has a plurality of steaming compartments disposed therein. A steam passage is disposed within the electric rice cooker body for transmitting steam between the two inner tanks, and a steam switch connected to the steam passage is mounted above the steam passage. Conventional electric rice cookers contain a high level of water content in steam, which can easily damage some pasta when steaming. Therefore, the present invention designs a double-tank household electric rice cooker. By disposing a steam passage within the electric rice cooker, steam from the two inner tanks can be communicated, thereby reducing the temperature of the steam and preventing it from damaging the steamed food. Furthermore, only one inner tank can be heated while the steam from the other inner tank, transmitted through the steam passage, can be heated together. This fully utilizes the energy within the electric rice cooker, saving a significant amount of resources.

[0006] The present invention provides two steaming systems, including two inner pots, two heating plates, two covers, several steaming trays, and a steam duct. The steam duct serves as a steam channel connecting the left and right inner pots of the rice cooker. The two systems can be used independently, simultaneously, or shared, with one side heating while the other shares the function. The power supply system of the rice cooker of the present invention utilizes a single-line power supply. After entering the rice cooker, the electricity is distributed to the two heating plates and other power-consuming systems. The two inner pots are designed side by side within the rice cooker body. The two covers are respectively used to seal against the two inner pots to generate pressure. Underneath each inner pot are heating plates that provide heat to the inner pots. The steam ducts on the inner pots are primarily used to hold food to be heated or steamed. Simultaneous operation of the two inner pots requires a steam duct located between the two inner pots. The steam duct is connected to a steam switch, which enables steam communication between the two inner pots upon activation. The steam in the electric rice cooker is transmitted from the top space of the inner pot of the electric rice cooker body to the cover of the electric rice cooker. A channel is provided around the cover or a space is reserved. After entering the cover, the steam is transmitted through the space or channel in the cover to a through hole preset on the bottom plane of the cover, which is connected to a first air hole or a second air hole provided on the upper plane of the electric rice cooker body, and then enters a steam channel pipe connected at both ends. The steam flows from the through hole on the inner side of the cover to the first air hole or the second air hole in the electric rice cooker, and then enters a first steam inlet or a second steam inlet of the steam channel pipe connected to the first air hole and the second air hole. Finally, the steam is transmitted to the other end of the electric rice cooker body through the steam channel pipe.

[0007] Preferably, a first steam inlet and outlet and a second steam inlet and outlet for steam in and out are respectively provided at both ends of the steam channel tube, and the steam switch is movably provided in the middle of the steam channel tube. The steam channel tube is used to receive the steam in the electric rice cooker. The first steam inlet and outlet and the second steam inlet and outlet are provided between the two inner pots, and are used to collect or receive steam at both ends of the electric rice cooker. That is, when the steam switch is turned on, the steam enters the steam channel tube from the steam inlet and outlet at one end of the steam channel tube, and is then discharged from the steam inlet and outlet at the other end, so that the steam at both ends is shared without damaging the heated food, and the function of heating one side and sharing the other side is achieved. At the same time, the steam can be fully utilized by using the steam channel tube, saving a lot of resource waste.

[0008] Preferably, a circular opening is provided in the middle of the steam duct for inserting a steam switch, and a connector is provided at the bottom of the steam switch, connected to the steam duct. The connector is provided with through holes for inserting the steam switch and the steam duct, respectively, and the steam switch and the connector are connected by threads or bayonet. One end of the steam switch is provided on the upper surface of the electric rice cooker body, and the other end is movably connected to the steam duct. When steam communication between the two inner pots is required, the steam switch is twisted to allow steam to flow between the two ends of the steam duct; when steam communication between the two inner pots is not required, the steam switch is twisted in the opposite direction to close, blocking steam communication between the two ends of the steam duct. By twisting the steam switch, steam communication between the two inner pots can be switched on and off. That is, by turning on the steam switch, one inner pot can be steamed while the other is steamed by the steam in the heated inner pot, or both inner pots can be heated simultaneously. The double-pot rice cooker of the present invention is flexible and convenient. When the two inner pots are not required to work simultaneously, the steam switch can be turned off.

[0009] Preferably, the electric rice cooker body is provided with a first accommodating cavity and a second accommodating cavity, and two inner pots are respectively arranged in the first accommodating cavity and the second accommodating cavity. The inner pots are used to hold food and are placed in the first accommodating cavity or the second accommodating cavity. They are not fixed and can be taken out for cleaning at any time.

[0010] Preferably, the electric rice cooker body is provided with a first air hole and a second air hole which are in communication with the first steam inlet and outlet and the second steam inlet and outlet, respectively. After the electric rice cooker starts working, the steam is transmitted from the top space of the inner pot of the electric rice cooker to the cover body, and then passes through the channel or space of the cover body, and then connects with the first air hole or the second air hole on the inner side of the top of the first accommodating cavity and the second accommodating cavity from the through hole on the inner side of the cover body. The steam is transmitted to the first steam inlet and outlet or the second steam inlet and outlet through the first air hole or the second air hole, and finally transmitted to the inner pot at the other end of the electric rice cooker body through the steam channel pipe. At the same time, the steam temperature becomes milder due to the transmission of the steam through the steam channel pipe, thereby avoiding the problem of food being damaged due to excessive moisture in the steam. The double-boiler electric rice cooker of the present invention can place easily damaged food in the other pot, such as steaming buns, steamed buns, etc. Since the double-boiler electric rice cooker has a double-boiler structure, steam can be communicated between the two inner pots over a long distance, and the temperature of the steam will become mild when it passes from one inner pot to the other. If the left side is heated and the right side is used, steamed buns, steamed buns, etc. can be steamed; if the right side is heated and the left side is used, steamed buns, steamed buns, etc. can also be steamed; and the steamed food is of excellent quality without any damage, which not only solves the problem of different tastes, but also saves a lot of steaming time and resource waste, and is much more convenient. On the other hand, the double-boiler electric rice cooker of the present invention can only open one inner pot for heating. Since steam can flow between the two inner pots through the steam channel tube, the other inner pot can use the steam from the heated inner pot to heat or steam food, so that energy is fully utilized and a lot of resources are saved.

[0011] Preferably, the first and second air holes are respectively provided on the inner sides of the tops of the first and second accommodating cavities. The first and second air holes on the inner sides of the upper portions of the first and second accommodating cavities are positioned higher within the rice cooker than the two inner pots. The first and second air holes are primarily used to connect with the first and second steam inlets and outlets at both ends of the steam passage tube. Steam flows into the steam passage tube through the first and second air holes, thereby achieving steam interconnection and connection between the two inner pots.

[0012] Specifically, the steam channel tube is fixed in the rice cooker body by threads. The threaded fixing structure is simple, easy to process, and firm and stable, so screw fixation is the optimal fixing method. Of course, processing and fixing methods such as bayonet connection can also be used, and the steam channel tube can stably transmit steam between the two inner pots.

[0013] Specifically, the rice cooker body is in a horizontal 8 shape or a rounded rectangle. The steam channel pipe of the present invention is arranged between the two inner pots inside the rice cooker body. In order to improve the overall visual effect, the outer shape of the rice cooker body can be designed into a horizontal 8 shape or a rounded rectangle.

[0014] The beneficial effects of the present invention are:

[0015] 1. The double-pot rice cooker of the present invention transmits steam to the inner pot at the other end of the rice cooker body through the steam passage. At the same time, the steam temperature becomes relatively mild due to the transmission of steam through the steam passage, avoiding excessive steam moisture that may damage food. It can cook multiple foods simultaneously while ensuring the safety and appearance of the food.

[0016] 2. The present invention realizes the multifunctional operation of the double-pot rice cooker through the design of the steam channel tube. The two inner pots are placed side by side, and only one inner pot can be opened for heating. Since steam can flow between the two pots through the steam channel tube, the other inner pot can use the steam from the heating inner pot to heat or steam food. Energy is fully utilized, a large amount of resources is saved, and multiple flavors of rice can be steamed simultaneously, which is convenient and fast.

[0017] 3. The present invention has reasonable design, compact structure, practicality and energy saving, which meets the needs of most families. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-2 As shown, this embodiment provides a double-tank household electric rice cooker, comprising an electric rice cooker body 1, a cover body 3 adapted to the electric rice cooker body 1, an inner pot 5 disposed within the electric rice cooker body 1, and a heating plate disposed below the inner pot 5. The electric rice cooker body 1 is provided with two parallel inner pots 5, each of which is provided with a plurality of steaming grids 6. A steam passage 2 is provided within the electric rice cooker body 1 for transmitting steam between the two inner pots 5, and a steam switch 4 connected to the steam passage 2 is installed above the steam passage 2. Conventional electric rice cookers are prone to damage when steaming some pasta due to the high moisture content of steam rising from the steam. Therefore, the present invention designs a double-tank household electric rice cooker. By providing the steam passage 2 within the electric rice cooker, the steam from the two inner pots 5 can be communicated, thereby making the steam temperature milder and less likely to damage the steamed food. At the same time, only one inner pot can be opened for heating, while the steam from the other inner pot transmitted through the steam passage 2 can be heated together. This fully utilizes the energy in the electric rice cooker, saving a large amount of resources.

[0023] The present invention features two steaming systems, including two inner pots 5, two heating plates, two lids 3, several steaming trays 6, and a steam duct 2. The steam duct 2 serves as a steam passage connecting the left and right inner pots 5. The two systems can be used independently, simultaneously, or even shared, with one heating and the other sharing functionality. The power supply system of the rice cooker utilizes a single-line power supply, whereby energy enters the rice cooker and is then distributed to the two heating plates and other power-consuming systems. The two inner pots 5 are positioned side by side within the rice cooker body 1. The two lids 3 are each designed to seal against the two inner pots 5 and create pressure. Below each inner pot 5 are located a heating plate to provide heat to the inner pots 5. The steaming trays 6 on the inner pots 5 are primarily used to hold food to be heated or steamed. Simultaneous operation of the two inner pots 5 requires a steam duct 2 located between the two pots 5. The steam duct 2 is connected to a steam switch 4, which activates the steam switch 4 to enable steam communication between the two pots 5. The steam in the rice cooker is transmitted from the top space of the inner pot 5 of the rice cooker body 1 to the cover 3 of the rice cooker. There is a channel or a reserved space around the cover 3. After the steam enters the cover 3, it is transmitted through the space or channel in the cover 3 to the preset through hole on the bottom plane of the cover 3 and docks with the first air hole 101 or the second air hole 102 set on the plane of the rice cooker body 1 to enter the steam channel tube 2 connecting the two ends. The steam will flow from the through hole on the inner side of the edge of the cover 3 to the first air hole 101 or the second air hole 102 in the rice cooker, and then enter the first steam inlet and outlet 201 or the second steam inlet and outlet 202 of the steam channel tube 2. Finally, the steam will be transmitted to the other end of the rice cooker body 1 through the steam channel tube 2. The steam in the rice cooker can be transmitted through the cover or directly without passing through the cover.

[0024] In this embodiment, the two ends of the steam channel tube 2 are respectively provided with a first steam inlet and outlet 201 and a second steam inlet and outlet 202 for steam in and out. The steam switch 4 is movably arranged in the middle of the steam channel tube 2. The steam channel tube 2 is used to receive the steam in the rice cooker. The first steam inlet and outlet 201 and the second steam inlet and outlet 201 are arranged between the two inner pots 5, and are used to collect or receive steam from both ends of the rice cooker. That is, when the steam switch 4 is turned on, the steam enters the steam channel tube 2 from the steam inlet and outlet 201 at one end of the steam channel tube 2, and is then discharged from the steam inlet and outlet 201 at the other end, so that the steam is shared at both ends without damaging the heated food, and the function of heating one side and sharing the other side is achieved.

[0025] In this embodiment, a circular opening is provided in the middle of the steam passage tube 2 for inserting the steam switch 4. A connector 203 is provided at the bottom of the steam switch 4, which is connected to the steam passage tube 2. The connector 203 has through holes for inserting the steam switch 4 and the steam passage tube 2, respectively. The steam switch 4 and the connector 203 are connected via threads or bayonet connections. Threaded or bayonet connections are the most preferred implementations of this embodiment; other connection methods are also within the scope of this embodiment. One end of the steam switch 4 is provided on the upper surface of the electric rice cooker body 1, and the other end is movably connected to the steam channel tube 2. When steam communication between the two inner pots 5 is required, the steam switch 4 is twisted to allow steam communication at both ends of the steam channel tube 2; when steam communication between the two inner pots 5 is not required, the steam switch 4 is twisted in the opposite direction to block steam communication at both ends of the steam channel tube 2. Steam communication between the two inner pots can be achieved and closed by twisting the steam switch 4, that is, by turning on the steam switch 4, one inner pot can be steamed and heated by the steam in the heated inner pot, or the two inner pots can be heated simultaneously. The double-pot electric rice cooker of the present invention is flexible and convenient. When the two inner pots are not required to work simultaneously, the steam switch 4 can be turned off.

[0026] In this embodiment, the rice cooker body 1 is provided with a first accommodating cavity and a second accommodating cavity, and two inner pots 5 are respectively arranged in the first accommodating cavity and the second accommodating cavity. The inner pots 5 are used to hold food and are placed in the first accommodating cavity or the second accommodating cavity. They are not fixed and can be taken out and cleaned at any time.

[0027] In this embodiment, the electric rice cooker body 1 is respectively provided with a first air hole 101 and a second air hole 102 which are communicated with the first steam inlet and outlet 201 and the second steam inlet and outlet 202. After the electric rice cooker starts working, the steam is transmitted from the top space of the electric rice cooker inner pot 5 to the cover body 3. The steam will pass through the channel or space of the cover body 3, and then dock with the first air hole 101 or the second air hole 102 on the inner side of the first accommodating cavity and the second accommodating cavity from the through hole on the inner side of the cover body 3. The steam is transmitted to the first steam inlet and outlet or the second steam inlet and outlet through the first air hole or the second air hole, and finally transmitted to the inner pot 5 at the other end of the electric rice cooker body 1 through the steam channel pipe 2. At the same time, the steam is transmitted through the steam channel pipe 2, and the steam temperature becomes relatively mild, thereby avoiding the problem of food damage due to excessive steam moisture.

[0028] In this embodiment, the first air hole 101 and the second air hole 102 are respectively provided on the inner side of the top of the first accommodating chamber and the second accommodating chamber. The first air hole 101 and the second air hole 102 on the inner side of the upper portion of the first accommodating chamber and the second accommodating chamber are positioned higher than the positions of the two inner pots 5 within the rice cooker. The first air hole 101 and the second air hole 102 are mainly used to connect with the first steam inlet and outlet 201 and the second steam inlet and outlet 201 at both ends of the steam passage tube 2. Steam flows into the steam passage tube 2 through the first air hole 101 or the second air hole 102, thereby achieving the steam interconnection and connection function of the two inner pots 5.

[0029] In the present embodiment, the steam duct 2 is fixed to the electric cooker body 1 by screws. The screw fixing structure is simple, easy to process, and firm and stable, so screw fixing is the optimal fixing method. Of course, processing and fixing methods such as bayonet connection can also be used. The connection method of the steam duct 2 and the electric cooker body 1 is based on whether the steam duct 2 can stably transmit steam between the two inner pots.

[0030] In this embodiment, the rice cooker body is in the shape of a horizontal figure 8 or a rounded rectangle. The steam channel tube of the present invention is arranged between the two inner pots inside the rice cooker body. In order to improve the overall visual effect, the external shape of the rice cooker body can be designed into a structure such as a horizontal figure 8 or a rounded rectangle.

[0031] Working principle: The double-pot household electric rice cooker of the present invention is provided with a steam channel tube for passing steam between the two inner pots in the electric rice cooker. The steam is transmitted from the top space of the inner pot of the electric rice cooker to the cover of the electric rice cooker. A channel is provided around the cover or a space is reserved, and a through hole is provided on the inner side of the cover. The steam will flow from the through hole on the inner side of the edge of the cover to the first air hole or the second air hole in the electric rice cooker, and then connect with the first steam inlet and outlet or the second steam inlet and outlet on the steam channel tube through the first air hole or the second air hole. Finally, the steam will be transmitted to the other end of the electric rice cooker body through the steam channel. The most important feature of the electric rice cooker of the present invention is that it can achieve energy saving. Since steam can be transmitted between the two inner pots through the steam channel, only one inner pot can be used for heating. When one inner pot is being heated while the other pot needs to steam other food, the steam switch can be turned on to transfer the steam in the heated inner pot to the other inner pot. In this way, while one inner pot is heating or steaming food, the steam in the other pot can be used to heat or steam other food without consuming electricity, thereby fully utilizing energy and saving energy. When the other inner pot is not needed, the steam switch can be turned off. Of course, the two inner pots can heat or steam at the same time or independently.

[0032] The present invention is not limited to the above optional embodiments. Anyone can derive various other forms of products based on the teachings of the present invention. The above specific embodiments should not be construed as limiting the scope of protection of the present invention. The scope of protection of the present invention shall be based on the scope defined in the claims, and the description can be used to interpret the claims.
