Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly relates to a household appliance for preventing insects. Background Art

[0002] If a household appliance is used in a kitchen, a warm and humid, relatively dirty and messy environment, since cockroaches and other insects prefer such environments, and the base of the household appliance usually has a grille specifically for the heat dissipation of internal components, after the household appliance is used for a long time, cockroaches and other insects may drill into the base of the household appliance through the grille, so that there may be live or dead cockroaches and other insects in the base. Summary of the Invention

[0003] In view of this, this application provides a household appliance for preventing insects and a cooking appliance having the same, so as to solve the technical problem that there may be live or dead cockroaches and other insects in the base of the household appliance in the prior art.

[0004] In a first aspect, this application provides a household appliance for preventing insects, and the household appliance includes: A housing, provided with a heat dissipation channel and a main control module; the heat dissipation channel communicates the inside of the housing with the outside; An insect prevention component, arranged in the heat dissipation channel, and the insect prevention component is electrically connected to the main control module; the insect prevention component is provided with a first grille and a second grille stacked; and at least one of the first grille and the second grille is made of a conductive material; Under an external force, the insect prevention component has a first position where the first grille and the second grille overlap each other for heat dissipation, and a second position where the first grille and the second grille are misaligned with each other for closing.

[0005] Advantageous Effects: In this embodiment, an insect prevention component is provided. The insect prevention component does not prevent the household appliance from dissipating heat. When in use, it switches to the first position to form a ventilation grille for heat dissipation. When not in use, it switches to the second position to cover and close the heat dissipation channel. Since this embodiment can energize the insect prevention component by using the main control module, therefore, no matter in which position, at least one grille in the insect prevention component can be charged, and after the insect touches the charged grille, it will be electrocuted. Usually, the user can directly check the heat dissipation channel, or lift the household appliance and shake it slightly to clean the insects out of the heat dissipation channel. Thus, the problem that there may be live or dead cockroaches and other insects in the base of the household appliance is solved.

[0006] In an optional embodiment, when the household appliance is operating, the main control module supplies power to the insect prevention component, and the insect prevention component switches from the second position to the first position; when the household appliance stops operating, the insect prevention component switches from the first position to the second position, and the main control module stops supplying power to the insect prevention component.

[0007] Beneficial effects: In this embodiment, the energized state of the insect-proof component is specifically set so that the energized state of the insect-proof component is consistent with the operating state of the household appliance. When the household appliance needs to dissipate heat, it switches to the first position and is energized. When an insect touches the insect-proof component, it will be electrocuted and die. Therefore, while the insect-proof component can dissipate heat from the household appliance, it can also prevent insects from entering the interior of the household appliance. When the household appliance stops operating, it switches to the second position to close the heat dissipation channel. Even if it is not energized, insects will not enter the interior of the household appliance. Therefore, this embodiment enables the insect-proof component not to remain energized for a long time, which can save a large amount of electric energy.

[0008] In an alternative embodiment, one of the first grille and the second grille is made of a conductive material, and the other is made of an insulating material.

[0009] Beneficial effects: In this embodiment, one grille is made of a conductive material and the other grille is made of an insulating material. Compared with energizing both grilles simultaneously, energizing only one grille can obviously save a lot of electric energy. At the same time, setting one of the grilles as an insulating material does not affect the insect-proof effect. For example, when an insect climbs onto the insulating grille when the insect-proof component is in the second position, once it switches from the second position to the first position, the insect will come into contact with the conductive grille during the switching process and will also be electrocuted and die.

[0010] In an alternative embodiment, the insect-proof component further includes: A driving device, connected to the first grille, and the driving device is electrically connected to the main control module; The second grille covers the heat dissipation channel, and the second grille is made of a conductive material and is electrically connected to the main control module; Under the driving action of the driving device, the first grille and the second grille switch between the first position and the second position.

[0011] Beneficial effects: In this embodiment, the position switching of the insect-proof component is realized by the driving device, which reduces the operation steps of the user. There is no need for the user to switch the position of the insect-proof component every time the household appliance is used. At the same time, it can also prevent the user from forgetting to switch the position of the insect-proof component, realizing automatic operation and improving the user experience.

[0012] In an alternative embodiment, a pull rod is provided at the driving end of the driving device, and the first grille is provided with a through hole suitable for the pull rod to be inserted. After the pull rod is inserted into the through hole, it is connected to the first grille.

[0013] In an alternative embodiment, the first grille is slidably disposed on the second grille through a sliding structure.

[0014] Beneficial effects: In this embodiment, a sliding structure is used between the first grille and the second grille to achieve position switching in a sliding manner, which can reduce the friction between the first grille and the second grille, thereby improving the smoothness of the driving device during operation and ensuring the normal operation of the overall device. Moreover, compared with direct friction, switching in a sliding manner can reduce the wear of the first grille and the second grille, extend the service life of the first grille and the second grille, and reduce the overall maintenance frequency of the device.

[0015] In an alternative embodiment, the sliding structure includes a slide bar provided on the first grille or the second grille, and a chute provided on the second grille or the first grille.

[0016] In an alternative embodiment, the insect-proof component further includes: An insulating structure provided on the inner wall of the heat dissipation channel, and the insulating structure surrounds to form an insulating cavity; the insulating cavity is used to install the grille with conductive material among the first grille and the second grille.

[0017] Beneficial effects: In this embodiment, an insulating structure is provided, which can insulate and wrap the first grille and the second grille, avoiding the high voltage from breaking through the housing during a long-term discharge process and causing harm to users, thereby improving the safety of the household appliance.

[0018] In an alternative embodiment, the insulating structure includes: At least two layers of insulating ribs provided on the inner wall of the heat dissipation channel, and the insulating ribs surround to form an insulating cavity.

[0019] In an alternative embodiment, an installation groove is formed between adjacent two layers of insulating ribs, and the edge of one of the first grille and the second grille is embedded in the installation groove for fixation.

[0020] Beneficial effects: In this embodiment, an installation groove is formed between adjacent two layers of insulating ribs, which can directly install one of the first grille and the second grille without an additional installation structure, improving the space utilization rate inside the housing, and enabling the insulating ribs to provide a certain installation and fixation effect while providing insulating protection.

[0021] In an alternative embodiment, connecting ribs are provided between adjacent two layers of insulating ribs.

[0022] Beneficial effects: In this embodiment, connecting ribs are provided between adjacent two layers of insulating ribs, which improves the overall structural strength of the insulating structure and avoids situations such as dislocation and cracking of the insulating structure due to aging of structural components during use.

[0023] In an alternative embodiment, an air inlet and outlet grille is provided on the side of the heat dissipation channel close to the outside.

[0024] In an alternative embodiment, the household appliance is at least a rice cooker.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0029] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "communicated" should be understood in a broad sense. For example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the connection inside two elements. It can be wirelessly connected or wired connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] If household appliances are used in an environment such as a kitchen, which is warm, humid, and relatively dirty and messy, since cockroaches and other insects prefer such an environment, and the base of household appliances usually has a grille specifically for the heat dissipation of internal components, after long-term use of household appliances, cockroaches and other insects may drill into the base of household appliances through the grille, resulting in the possible presence of live or dead cockroaches and other insects in the base.

[0031] In view of this, the present application provides an insect-proof household appliance and a cooking appliance having the same, so as to solve the technical problem that live or dead cockroaches and other insects may appear in the base of the household appliance in the prior art.

[0032] The following will be combined with Figures 1 to 8 , to describe the embodiments of the present application.

[0033] As Figures 1 to 8 shown, according to an embodiment of the present application, on the one hand, the present application provides an insect-proof household appliance, and the household appliance includes a housing 1 and an insect-proof component 2.

[0034] Specifically, in this embodiment, the housing 1 is provided with a heat dissipation channel 11 and a main control module 12. The heat dissipation channel 11 communicates the interior of the housing 1 with the external environment. Since the main control module 12 is disposed within the housing 1, and during operation, the main control module 12 and other structural components within the housing 1 generate heat, the heat dissipation channel 11 connects the interior of the housing 1 with the outside world to dissipate heat from all the structural components within the housing 1. Of course, a heat dissipation fan can also be specifically provided within the housing 1 to improve the heat dissipation capacity of the household appliance.

[0035] Further, in this embodiment, the insect-proof component 2 is disposed in the heat dissipation channel 11 and is electrically connected to the main control module 12. The insect-proof component 2 is provided with a first grille 21 and a second grille 22 stacked thereon, and at least one of the first grille 21 and the second grille 22 is made of a conductive material. That is to say, it can be that only the first grille 21 is made of a conductive material, or only the second grille 22 is made of a conductive material, or both the first grille 21 and the second grille 22 are made of a conductive material. During actual use, the user can control the main control module 12 to supply power to the insect-proof component 2 alone according to actual needs, so that the grille with conductive properties is charged, thereby achieving an insect-proof effect. When an insect touches the charged grille, the insect will die due to electric shock.

[0036] Further, when in use, the user can manually operate the insect-proof component 2 to switch its position. Under an external force, as Figure 4 shown, the insect-proof component 2 has a first position where the first grille 21 and the second grille 22 overlap each other for heat dissipation, and as Figure 5 shown, a second position where the first grille 21 and the second grille 22 are misaligned to be closed. That is to say, when the user uses the household appliance and heat dissipation is required, it can be switched to the first position. When heat dissipation is not required or the household appliance is turned off, it is switched to the second position. Of course, the user can supply power to the insect-proof component 2 according to actual conditions. The user can operate the main control module 12 to continuously supply power to the insect-proof component 2, so that the insect-proof component 2 is always in a charged state, or can supply power to the insect-proof component 2 only when the household appliance is in use, or can supply power when there are more insects at home.

[0037] Of course, this embodiment only gives examples of the power-on time of the user for the insect-proof component 2, but does not limit this. Those skilled in the art can make changes according to actual situations as long as the same technical effects can be achieved.

[0038] With such a setting, in this embodiment, an insect-proof component 2 is provided. The insect-proof component 2 does not prevent the household appliance from dissipating heat. When in use, it switches to the first position to form a ventilation grille for heat dissipation. When not in use, it switches to the second position to cover and close the heat dissipation channel 11. Since in this embodiment, the main control module 12 can power on the insect-proof component 2, therefore, no matter in which position, at least one grille in the insect-proof component 2 can be electrified. After the insect touches the electrified grille, it will be electrocuted to death. Usually, the user can directly check the heat dissipation channel 11, or lift the household appliance and shake it slightly to clean the insects out of the heat dissipation channel 11. Thus, the problem that live insects or corpses of cockroaches and other insects may appear at the base of the household appliance is solved.

[0039] Further, in an optional implementation manner, when the household appliance is operating, the main control module 12 supplies power to the insect-proof component 2, and the insect-proof component 2 switches from the second position to the first position. When the household appliance stops operating, the insect-proof component 2 switches from the first position to the second position, and the main control module 12 stops supplying power to the insect-proof component 2.

[0040] That is to say, when using the household appliance, it switches to the ventilation and heat dissipation position and is powered on, so that it can play an insect-proof effect while dissipating heat. If when the insect-proof component 2 is closed, the insects have already entered outside the heat dissipation channel 11 and there is a certain probability of staying on the non-electrified grille, then when switching to the ventilation and heat dissipation position, the grille is electrified at the same time, and the insects will be electrocuted when they touch the electrified grille. Or if the insects crawl inward, they will also touch the electrified grille and be electrocuted to death. When not using the household appliance, it directly switches to the second position for closing, so that the insects will not enter the inside of the housing 1.

[0041] With such a setting, in this embodiment, the power-on state of the insect-proof component 2 is specifically set, so that the power-on state of the insect-proof component 2 is consistent with the operating state of the household appliance. When the household appliance needs to dissipate heat, it switches to the first position and is powered on. When the insects touch the insect-proof component 2, they will be electrocuted to death. Therefore, the insect-proof component 2 can dissipate heat for the household appliance while preventing insects from entering the inside of the household appliance. When the household appliance stops operating, it switches to the second position to close the heat dissipation channel 11. Even if it is not powered on, the insects will not enter the inside of the household appliance. Therefore, this embodiment enables the insect-proof component 2 not to need to maintain the power-on state for a long time, and can save a large amount of electric energy.

[0042] Further, in an optional implementation manner, one of the first grille 21 and the second grille 22 is made of a conductive material, and the other is made of an insulating material. In this embodiment, an example is given with the first grille 21 being made of an insulating material and the second grille 22 being made of a conductive material.

[0043] With such a setting, in this embodiment, one grid is made of a conductive material and the other grid is made of an insulating material. Compared with energizing both grids simultaneously, energizing only one grid can obviously save a lot of electrical energy. At the same time, setting one of the grids as an insulating material will not affect the insect-proof effect. For example, when an insect climbs onto the insulating grid when the insect-proof component 2 is in the second position, once it switches from the second position to the first position, the insect will come into contact with the conductive grid during the switching process and will also be electrocuted to death.

[0044] Further, in an alternative embodiment, as Figures 1 to 5 , Figure 7 shown, the insect-proof component 2 further includes a driving device 25. The driving device 25 is connected to the first grid 21, and the driving device 25 is electrically connected to the main control module 12 through the first wire 23. The second grid 22 covers the heat dissipation channel 11, and the second grid 22 is made of a conductive material. The second grid 22 is electrically connected to the main control module 12 through the second wire 24. Under the driving action of the driving device 25, the first grid 21 and the second grid 22 are switched between the first position and the second position.

[0045] That is to say, the main control module 12 supplies power to the driving device 25 alone through the first wire 23 and controls the working state of the driving device 25, and then supplies the insect-killing voltage to the second grid 22 alone through the second wire 24.

[0046] During the actual working process, as described above, the main control module 12 can control the working state of the driving device 25. When the household appliance is operating or is powered on again after being awakened from the standby state, the main control module 12 controls the driving device 25 to switch the insect-proof component 2 from the second position to the first position. And at the same time, supply the insect-killing voltage to the second grid 22. When the household appliance stops operating, the main control module 12 controls the driving device 25 to switch the insect-proof component 2 from the first position to the second position, and at the same time stops supplying the insect-killing voltage to the second grid 22.

[0047] Further, in this embodiment, the driving device 25 can be a reciprocating motor and can be a lead screw motor. Of course, this embodiment is only an example of the type of the driving device 25, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0048] With such a setting, in this embodiment, the position switching of the insect-proof component 2 is realized through the driving device 25, which reduces the operation steps of the user. There is no need for the user to switch the position of the insect-proof component 2 every time the household appliance is used. At the same time, it can also prevent the user from forgetting to switch the position of the insect-proof component 2, realizing automatic operation and improving the user experience.

[0049] Further, in an optional embodiment, as Figures 2 to 5 , Figure 7 As shown, the driving end of the driving device 25 is provided with a pull rod 26, and the first grid 21 is provided with a through hole suitable for the pull rod 26 to be inserted. After the pull rod 26 is inserted into the through hole, it is connected with the first grid 21. It can be seen that the pull rod 26 and the through hole can be interference fit, and fixation can be achieved by using the restriction between the structures.

[0050] Of course, further, the pull rod 26 and the through hole can also be fixedly connected. For the fixed connection, welding, bonding and the like can be used. For the detachable connection, screws and screw holes can be used for fixing, buckles and slots can be used for fixing, and magnetic sheets can be used for fixing.

[0051] The following is an example of a detachable connection method. For example, additional fixing plates can be provided on both sides of the through hole. Those skilled in the art can change the number of fixing plates according to actual conditions, such as 1, 2, 3, 4, etc., and then open a screw hole on the fixing plate, and then open another screw hole on the pull rod 26 at the position corresponding to the screw hole, and then pass the screw through the screw hole on the fixing plate and the screw hole on the pull rod 26 in sequence, thereby connecting the through hole and the pull rod 26. Further, when fixing by means of a buckle and a slot, an additional buckle can be provided on the through hole. Those skilled in the art can change the number of buckles according to actual conditions, such as 1, 2, 3, 4, etc., and then open a slot on the pull rod 26 corresponding to the position of the buckle that can cooperate with the buckle, and then directly embed the buckle on the through hole into the slot on the pull rod 26, thereby connecting the through hole and the pull rod 26. When fixing by magnetic attraction, additional magnetic sheets can be arranged in the through hole. The technicians in this field can change the number of magnetic sheets according to the actual situation, 1, 2, 3, 4, etc., and then open the opposite magnetic sheets that can be attracted to the magnetic sheets at the positions corresponding to the magnetic sheets on the pull rod 26. Then, the magnetic sheets on the through hole are directly aligned with the opposite magnetic sheets embedded in the pull rod 26, so as to magnetically connect the through hole and the pull rod 26.

[0052] Of course, this embodiment is only an example of a fixed connection method and a detachable connection method, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

[0053] Further, in an optional embodiment, as Figure 3As shown, the first grille 21 is slidably disposed on the second grille 22 through a sliding structure 3. For the type of the sliding structure 3, it can be a pulley rail, or it can be a slider chute 32. Of course, this embodiment is only an example for the type of the sliding structure 3, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0054] With such a setting, in this embodiment, the position switching between the first grille 21 and the second grille 22 is realized in a sliding manner by using the sliding structure 3, which can reduce the friction between the first grille 21 and the second grille 22, and further improve the smoothness of the driving device 25 during operation, ensuring the normal operation of the overall device. Moreover, compared with direct friction, the switching in a sliding manner can reduce the wear of the first grille 21 and the second grille 22, extend the service life of the first grille 21 and the second grille 22, and reduce the maintenance frequency of the overall device.

[0055] Further, in an alternative embodiment, as Figure 3 shown, the sliding structure 3 is a slide bar 31 provided on the first grille 21 or the second grille 22, and a chute 32 provided on the second grille 22 or the first grille 21.

[0056] Further, in an alternative embodiment, as Figure 5 、 Figure 8 shown, the insect-proof component 2 further includes an insulating structure 5. The insulating structure 5 is disposed on the inner wall of the heat dissipation channel 11, and the insulating structure 5 surrounds to form an insulating cavity. The insulating cavity is used to install the grille with conductive material among the first grille 21 and the second grille 22. That is to say, when the first grille 21 is made of insulating material and the second grille 22 is made of conductive material, the second grille 22 can be installed in the insulating cavity for insulation to protect the user. The first grille 21 can be installed outside the insulating cavity, and the insulating material will not affect the components inside the housing 1.

[0057] With such a setting, this embodiment provides the insulating structure 5, which can insulate and wrap the first grille 21 and the second grille 22, avoiding the breakdown of the high voltage on the housing 1 during the long-term discharge process and causing harm to the user, thereby improving the safety of the household appliance.

[0058] Further, in an alternative embodiment, as Figure 8As shown in the figure, the insulation structure 5 includes at least two layers of insulation ribs 51. The insulation ribs 51 are arranged on the inner wall of the heat dissipation channel 11, and the insulation ribs 51 enclose to form an insulation cavity. As for the number of the insulation ribs 51, it can be two layers, three layers, four layers, five layers, and so on. Of course, this embodiment is only an example for the type of the insulation ribs 51, but it is not limited thereto. Those skilled in the art can change according to the actual situation as long as the same technical effects can be achieved.

[0059] Further, in an alternative embodiment, as Figure 8 shown in the figure, an installation groove 52 is formed between two adjacent layers of insulation ribs 51, and the edge of one of the first grille 21 and the second grille 22 is embedded in the installation groove 52 for fixation.

[0060] With such a setting, in this embodiment, an installation groove 52 is formed between two adjacent layers of insulation ribs 51, and one of the first grille 21 and the second grille 22 can be directly installed without additionally arranging an installation structure, improving the space utilization rate inside the housing 1, so that the insulation ribs 51 can provide a certain installation and fixation effect while providing insulation protection.

[0061] Further, in an alternative embodiment, as Figure 8 shown in the figure, a connecting rib 53 is arranged between two adjacent layers of insulation ribs 51. In this embodiment, two layers of insulation ribs 51 can be arranged, the height of the insulation ribs 51 needs to be greater than 8 mm, and the height of the connecting rib 53 needs to be not less than 6 mm, and space needs to be reserved for the installation groove 52. Of course, this embodiment is only an example for the specific parameters of the insulation ribs 51 and the connecting rib 53, but it is not limited thereto. Those skilled in the art can change according to the actual situation as long as the same technical effects can be achieved.

[0062] With such a setting, in this embodiment, a connecting rib 53 is arranged between two adjacent layers of insulation ribs 51, improving the overall structural strength of the insulation structure 5 and avoiding the situation that the insulation structure 5 is displaced or cracked due to the aging of structural components during use.

[0063] Further, in an alternative embodiment, as Figure 5 、 Figure 8 shown in the figure, an air inlet and outlet grille 4 is arranged on the side of the heat dissipation channel 11 close to the outside.

[0064] Further, in an alternative embodiment, the household appliance is at least a rice cooker. Of course, it can also be a soybean milk machine, a wall breaker, a kettle, and so on. Of course, this embodiment is only an example for the type of the household appliance, but it is not limited thereto. Those skilled in the art can change according to the actual situation as long as the same technical effects can be achieved.

[0065] Although embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope defined by the appended claims.
