Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an exhaust system of an integrated range hood and an integrated range hood. Background Art

[0002] An integrated range hood, also known as an environmental protection range hood or an integrated environmental protection range hood, is a kitchen appliance that integrates multiple functions such as a smoke exhaust machine, a gas stove, a disinfection cabinet, and a storage cabinet. It has the advantages of saving space, good smoke exhaust effect, energy saving, low consumption, and environmental protection.

[0003] Among them, the smoke exhaust machine is used to extract the oil fume during the cooking process, so as to avoid affecting the health of users and reduce the oil fume adhering to the kitchen utensils and kitchen walls. The smoke exhaust machine includes an exhaust system of the integrated range hood, and the exhaust system of the integrated range hood is used to quickly extract and discharge the oil fume outdoors during the cooking process. Specifically, the exhaust system of the integrated range hood includes a fan assembly, and the fan assembly can inhale the oil fume and discharge it outdoors. However, in the prior art, the fan assembly is generally integrated with other functional modules such as a gas stove, a disinfection cabinet, and a storage cabinet on the integrated range hood main body. Since the volume of the fan assembly is relatively large, the space of the integrated range hood main body occupied by the fan assembly is relatively large, which is not conducive to the multi-functional integration of the integrated range hood. On the other hand, a relatively large noise will be generated during the operation of the fan assembly. Since the fan assembly is integrated with the gas stove on the integrated range hood main body, during the cooking process, the user is directly close to the noise source, thus affecting the user experience.

[0004] Therefore, the above problems need to be solved urgently. Summary of the Utility Model

[0055] Please refer to Figures 1 to 27 , this embodiment provides an integrated stove, which includes an integrated stove main body 1, a cooking range (not shown in the figure), and an integrated stove exhaust system 2. The cooking range is integrated on the integrated stove main body 1, and the integrated stove exhaust system 2 is configured to exhaust the cooking fumes generated during the cooking process of the cooking range to the outside.

[0056] In this embodiment, the integrated stove exhaust system 2 includes a first cabinet 21, a fan assembly 22, and an exhaust duct 23. The first cabinet 21 is arranged at an interval from the integrated stove main body 1. An air inlet (not shown in the figure) and an air outlet (not shown in the figure) are provided on the first cabinet 21. The fan assembly 22 is installed in the first cabinet 21. The air inlet of the fan assembly 22 is communicated with the air inlet, the air outlet of the fan assembly 22 is communicated with the air outlet, one end of the exhaust duct 23 is communicated with the space above the cooking range, and the other end of the exhaust duct 23 is communicated with the air inlet.

[0057] Based on the above, in this embodiment, the fan assembly 22 is placed outside the integrated stove main body 1 and away from the integrated stove main body 1. On the one hand, there is no need to arrange the fan assembly 22 inside the integrated stove main body 1, which facilitates the multi-functional integration of the integrated stove. On the other hand, since the fan assembly 22 is far from the integrated stove main body 1, during the cooking process, the user is away from the noise source, thus avoiding the noise generated by the fan assembly 22 from affecting the user experience.

[0058] It can be understood that the fan assembly 22 in this embodiment is a centrifugal fan. Of course, in other alternative embodiments, the fan assembly 22 can also be an axial flow fan or an inclined flow fan, etc. There is no specific limitation in this embodiment. In addition, since the specific structure and working principle of the fan assembly 22 are both prior arts, they will not be elaborated in this embodiment.

[0059] Preferably, the integrated stove exhaust system 2 further includes a second cabinet 24. The second cabinet 24 is installed between the integrated stove main body 1 and the first cabinet 21, and the exhaust duct 23 is installed in the second cabinet 24, thus avoiding affecting the user's perception due to the exposure of the exhaust duct 23. In addition, the second cabinet 24 can also protect the exhaust duct 23, thus avoiding the exhaust duct 23 from being damaged by external objects due to exposure.

[0060] Furthermore, the integrated stove exhaust system 2 further includes a ventilation pipeline. The ventilation pipeline is arranged on the integrated stove main body 1. One end of the ventilation pipeline is communicated with the space above the cooking stove, and the other end of the ventilation pipeline is communicated with the exhaust duct 23, so as to extract and discharge the generated cooking fumes outdoors during the cooking process. Based on the above, in this embodiment, only the ventilation pipeline of the integrated stove exhaust system 2 is arranged inside the integrated stove main body 1, which facilitates the multi-functional integration of the integrated stove.

[0061] In this embodiment, the integrated stove main body 1 includes a first cabinet door (not shown in the figure), a first side plate 11 and a second side plate 12. The first side plate 11 and the second side plate 12 are arranged opposite to each other along the first direction. The cooking stove is installed on the tops of the first side plate 11 and the second side plate 12. The first cabinet door is installed on one side of the first side plate 11 and the second side plate 12 along the second direction, and the second direction is perpendicular to the first direction. The ventilation pipeline is arranged between the first side plate 11 and the second side plate 12 and is located on the other side of the first side plate 11 and the second side plate 12 along the second direction, so as to provide sufficient space for installing other functional modules such as a disinfection cabinet and a storage cabinet, and further facilitate the multi-functional integration of the integrated stove.

[0062] It can be understood that the above-mentioned first cabinet door is the cabinet door of the disinfection cabinet, storage cabinet and other cabinets.

[0063] Further, in this embodiment, the first side plate 11 includes a first plate portion 111, and a second plate portion 112 is detachably mounted on one side of the first plate portion 111 along the second direction. The second side plate 12 includes a third plate portion 121, and a fourth plate portion 122 is detachably mounted on one side of the third plate portion 121 along the second direction. The first plate portion 111 and the third plate portion 121 are disposed opposite to each other along the first direction, the first direction is perpendicular to the second direction, the third plate portion 121 and the fourth plate portion 122 are disposed opposite to each other along the first direction, and the cooking top of the integrated range hood is mounted on the tops of the first side plate 11 and the second side plate 12.

[0064] Based on the above, the first side plate 11 and the second side plate 12 form a set of side plates. Both the first side plate 11 and the second side plate 12 are split structures, so that the lengths of the first side plate 11 and the second side plate 12 along the second direction can be adaptively selected according to requirements, and further the space depth between the first side plate 11 and the second side plate 12 can be adaptively adjusted.

[0065] In this embodiment, the second plate portion 112 can be mounted on the first plate portion 111 or removed from the first plate portion 111 according to requirements. The fourth plate portion 122 can be mounted on the third plate portion 121 or removed from the third plate portion 121 according to requirements. Moreover, in this embodiment, the second plate portion 112 and the fourth plate portion 122 with different lengths can be replaced according to actual requirements. Compared with developing a mold for manufacturing the corresponding side plate for each requirement, in this embodiment, both the first side plate 11 and the second side plate 12 are split into two plate members. Although the number of types of molds to be developed remains the same, the size of each mold is reduced, so that the mold development cost can be saved. In addition, for different product requirements, the required first plate portion 111 and third plate portion 121 remain the same. The difference lies only in whether the second plate portion 112 and the fourth plate portion 122 need to be installed and the sizes of the second plate portion 112 and the fourth plate portion 122. Therefore, for different product requirements, the manufacturer can uniformly produce the first plate portion 111 and the third plate portion 121, and simultaneously produce the second plate portion 112 and the fourth plate portion 122 according to needs. Compared with producing large-sized plate members, producing small-sized plate members takes less time, so that the production efficiency can be improved, and further it is beneficial to automated mass production.

[0066] Specifically, the first plate portion 111 and the third plate portion 121 are base plate members, the second plate portion 112 is an additional plate member attached to the first plate portion 111, and the fourth plate portion 122 is an additional plate member attached to the third plate portion 121. Since the first side plate 11 and the second side plate 12 have the same principle, in this embodiment, only the first side plate 11 will be described. Specifically, in this embodiment, five product requirements are taken as examples for description, that is, the manufacturer needs to produce the first side plate 11 in five sizes. Based on the content described above, the manufacturer needs to develop a first mold for producing the first plate portion 111 and four second molds for producing the second plate portion 112. The four second molds are respectively used to produce the second plate portion 112 in four sizes, so that five sizes of the first side plate 11 can be obtained. One of the first side plates 11 only includes the first plate portion 111, and the other four first side plates 11 are the first plate portion 111 paired with the second plate portion 112 in different sizes. Although the number of types of molds to be developed remains unchanged, the size of each mold is reduced, thereby saving the mold development cost.

[0067] In addition, for mass production, the manufacturer uniformly produces the first plate portion 111 and produces the second plate portion 112 in different sizes according to actual needs. The production quantities of the second plate portions 112 in different sizes are specifically determined according to actual needs. Compared with producing large-sized plate members, the time spent on producing small-sized plate members is shorter, thereby improving the production efficiency and facilitating automated mass production.

[0068] Preferably, a plurality of first positioning grooves 1111 are provided on one of the first plate portion 111 and the second plate portion 112, and a plurality of first positioning plates 1121 are provided on the other of the first plate portion 111 and the second plate portion 112. The plurality of first positioning plates 1121 can be respectively clamped in the plurality of first positioning grooves 1111, so that the second plate portion 112 can be assembled to one side of the first plate portion 111 along the second direction or the second plate portion 112 can be removed from the first plate portion 111. The first positioning grooves 1111 and the first positioning plates 1121 can cooperate together to position the second plate portion 112.

[0069] Correspondingly, a plurality of second positioning grooves 1211 are provided on one of the third plate portion 121 and the fourth plate portion 122, and a plurality of second positioning plates 1221 are provided on the other of the third plate portion 121 and the fourth plate portion 122. The plurality of second positioning plates 1221 can be respectively clamped in the plurality of second positioning grooves 1211, so that the fourth plate portion 122 can be assembled to one side of the third plate portion 121 along the second direction or the fourth plate portion 122 can be removed from the third plate portion 121. The second positioning grooves 1211 and the second positioning plates 1221 can cooperate together to position the fourth plate portion 122.

[0070] It can be understood that, to ensure that the second plate portion 112 can be stably installed on the first plate portion 111, after the second plate portion 112 is assembled onto the first plate portion 111, the second plate portion 112 can be fixed to the first plate portion 111 by means such as bolt connection. Correspondingly, to ensure that the fourth plate portion 122 can be stably installed on the third plate portion 121, after the fourth plate portion 122 is assembled onto the third plate portion 121, the fourth plate portion 122 can be fixed to the third plate portion 121 by means such as bolt connection.

[0071] In addition, the integrated cooking stove main body 1 further includes a bottom plate 13. The first side plate 11 abuts against one side of the bottom plate 13 along the first direction, and the second side plate 12 abuts against the other side of the bottom plate 13 along the first direction. Thus, during the process of assembling the integrated cooking stove main body 1, the first side plate 11 and the second side plate 12 are positioned in the first direction.

[0072] Furthermore, both the first side plate 11 and the second side plate 12 are inserted into the bottom plate 13, which facilitates the disassembly and assembly of the first side plate 11 and the second side plate 12, and can also position the first side plate 11 and the second side plate 12 in the second direction.

[0073] Preferably, in this embodiment, the bottom plate 13 is turned up to form a first flanging 131, and the first flanging 131 is turned up along the second direction towards the side away from the bottom plate 13 to form a second flanging 132. The first side plate 11 is provided with a third flanging 113 and a fourth flanging 114. The third flanging 113 abuts against the side of the first flanging 131 close to the bottom plate 13, and the fourth flanging 114 abuts against the top of the second flanging 132. That is, the third flanging 113 and the fourth flanging 114 cover the inner sides of the first flanging 131 and the second flanging 132. The second side plate 12 is provided with a fifth flanging 123 and a sixth flanging 124. The fifth flanging 123 abuts against the side of the first flanging 131 close to the bottom plate 13, and the sixth flanging 124 abuts against the top of the second flanging 132. That is, the fifth flanging 123 and the sixth flanging 124 also cover the inner sides of the first flanging 131 and the second flanging 132. Thereby, the first side plate 11, the second side plate 12 and the bottom plate 13 form a whole, which improves the rigidity of the integrated cooking stove main body 1, so as to avoid deformation of the frame of the integrated cooking stove main body 1 during movement, and avoid deformation of the bottom plate 13 due to the pressure of the functional modules of the integrated cooking stove installed on its top.

[0074] Moreover, based on the above, an avoidance groove 133 is formed on the outer sides of the first flanging 131 and the second flanging 132, so that pipes such as gas pipes can be arranged when the integrated cooking stove is installed against the wall.

[0075] Further, a perforation 1311 is formed in the first flanging 131. The perforation 1311 is configured to pass a wire for electrically connecting the integrated stove to an external power supply. That is, the perforation 1311 for wire routing is formed in the first flanging 131, so that there is no need to additionally install a power connection box structure on the integrated stove, reducing costs.

[0076] Based on the content mentioned above, the integrated stove main body 1 further includes a back plate 14. The back plate 14 abuts between the first plate portion 111 and the third plate portion 121 and is placed on the second flanging 132. A ventilation pipeline is formed inside the back plate 14. Based on the above, one end of the ventilation pipeline communicates with the space above the cooking range, and the other end of the ventilation pipeline communicates with the fan assembly 22 of the integrated stove, so as to suck away the generated cooking fumes and discharge them outdoors during the cooking process. In this embodiment, the ventilation pipeline is integrated on the back plate 14. On the one hand, it saves occupied space, which is beneficial to the multi-functional integration of the integrated stove. On the other hand, it is also convenient for disassembly and maintenance.

[0077] Further, a seventh flanging 134 is formed by folding the side of the second flanging 132 away from the first flanging 131 upward. Both sides of the back plate 14 along the first direction are folded to form eighth flangings 141. The eighth flangings 141 are located on the side of the back plate 14 away from the bottom plate 13 along the second direction. The seventh flanging 134 abuts between the two eighth flangings 141. The bottom of the back plate 14 is folded toward the side close to the bottom plate 13 along the second direction to form a ninth flanging 142. The ninth flanging 142 fits against the top of the second flanging 132, so that the back plate 14 and the bottom plate 13 form a whole, and further improves the rigidity of the integrated stove main body 1.

[0078] In addition, a tenth flanging 115 is formed by folding the side of the first plate portion 111 toward the third plate portion 121 along the first direction. The tenth flanging 115 abuts against the side of the back plate 14 close to the bottom plate 13 along the second direction. While an eleventh flanging 125 is formed by folding the side of the third plate portion 121 toward the first plate portion 111 along the first direction. The eleventh flanging 125 abuts against the side of the back plate 14 close to the bottom plate 13 along the second direction, so that the first side plate 11, the second side plate 12, the back plate 14 and the bottom plate 13 form a whole, and further improves the rigidity of the integrated stove main body 1.

[0079] Preferably, a groove 135 is provided at the bottom of the bottom plate 13. A first floor foot 136 is screwed to the bottom of the groove 135, and a second floor foot 137 is screwed to the portion of the bottom plate 13 outside the groove 135. That is, the screwing position of the first floor foot 136 on the bottom plate 13 is higher than the screwing position of the second floor foot 137 on the bottom plate 13. Both the first floor foot 136 and the second floor foot 137 can be used to adjust the height of the integrated stove main body 1, so as to increase the height adjustment range of the integrated stove main body 1 and meet the needs of different users.

[0080] In addition, based on the content mentioned above, in this embodiment, the integrated cooking stove main body 1 further includes a back plate 14. A ventilation pipeline is formed inside the back plate 14. Specifically, the back plate 14 is hollow and includes a first plate member 143 and a second plate member 144 that are oppositely arranged in the second direction. The second direction is perpendicular to the first direction. A first opening 145 is formed at the top of the back plate 14, and a second opening 146 is formed on one side of the back plate 14 along the first direction. The first opening 145 communicates with the space above the cooking stove, and the second opening 146 communicates with the blower assembly 22 of the integrated cooking stove. The integrated cooking stove main body 1 further includes a deflector 15. The deflector 15 abuts between the first plate member 143 and the second plate member 144 and divides the internal cavity of the back plate 14 into a first chamber 147 and a second chamber 148. Both the first opening 145 and the second opening 146 communicate with the first chamber 147. The deflector 15 and the first plate member 143 and the second plate member 144 jointly enclose a ventilation pipeline. The ventilation pipeline is located on the side of the deflector 15 close to the first opening 145 and the second opening 146. In this embodiment, a plurality of through holes 151 are evenly distributed on the deflector 15, thereby forming a microporous noise reduction structure on the deflector 15.

[0081] Based on the above, in this embodiment, the cooking fume can enter the first chamber 147 through the first opening 145 and flow out through the second opening 146. The cooking fume flowing out from the second opening 146 can flow to the blower assembly 22 and then be discharged outdoors. The deflector 15 is used to deflect the cooking fume entering the first chamber 147 through the first opening 145. During the flow of the cooking fume, the cooking fume will impact the deflector 15 that encloses the ventilation pipeline. Since a microporous noise reduction structure is formed on the deflector 15, the noise generated by the cooking fume impacting the deflector 15 is relatively small, thus avoiding affecting the user experience.

[0082] Furthermore, the deflector 15 is arc-shaped and bends towards the side away from the first opening 145 and the second opening 146. Since the cross-section of the deflector 15 is a curved surface, the flow resistance of the surface of the deflector 15 in contact with the cooking fume can be reduced, and thus the flow efficiency can be improved. That is, in this embodiment, the cooking fume generated during the cooking process can be quickly discharged outdoors, further avoiding affecting the user experience.

[0083] Furthermore, the second plate 144 is located inside the integrated stove main unit 1, and a positioning sink 1431 is provided on the side of the first plate 143 close to the second plate 144, and a first folded edge 152 is provided on the side of the guide plate 15 along the second direction. The first folded edge 152 is sunk into the positioning sink 1431 and fits against the bottom wall of the positioning sink 1431, and the side of the guide plate 15 away from the first opening 145 and the second opening 146 is in contact with the side wall of the positioning sink 1431, so that the guide plate 15 can be positioned, thereby facilitating the assembly of the guide plate 15 and conveniently fixing the guide plate 15.

[0084] In addition, an air outlet seat 25 is installed on the back panel 14, one end of the air outlet seat 25 is connected to the second opening 146, and the other end of the air outlet seat 25 is inserted into the first side panel 11 and connected to the fan assembly 22, so that the fan assembly 22 is arranged outside the integrated stove host 1 to avoid the noise generated by the fan assembly 22 affecting the user's experience.

[0085] Based on the above content, a mounting hole 116 is provided on the first side panel 11, and the first side panel 11 is mounted on the outer periphery of the air outlet seat 25 through the mounting hole 116. The hole wall of the mounting hole 116 is folded along the first direction toward the side close to the back panel 14 to form a second folded edge 117. The second folded edge 117 extends into the air outlet seat 25 and fits with the inner wall of the air outlet seat 25, thereby preventing the oil attached to the air outlet seat 25 from leaking from the connection between the first side panel 11 and the mounting seat.

[0086] Since the side of the first plate 143 away from the second plate 144 is the rear wall of the integrated stove main unit 1, and the integrated stove main unit 1 is generally placed against the wall, that is, the side of the first plate 143 away from the second plate 144 is generally placed against the wall, therefore, in order to facilitate the arrangement of the exhaust duct 23 connected between the air outlet seat 25 and the fan assembly 22, in this embodiment, the distance between the second opening 146 and the first plate 143 in the second direction is smaller than the distance between the mounting hole 116 and the first plate 143 in the second direction, so that the side of the air outlet seat 25 away from the back panel 14 is offset relative to the side of the air outlet seat 25 close to the back panel 14 toward the side away from the first plate 143, thereby facilitating the arrangement of the exhaust duct 23.

[0087] In addition, the integrated stove further includes a machine head 3, which is installed at the top of the back plate 14. An air suction port 31 is provided on the machine head 3. The air suction port 31 is located above the cooking range, and the first opening 145 is communicated with the air suction port 31. Specifically, the integrated stove main body 1 further includes a ventilation base 16, which is installed at the top of the back plate 14. The machine head 3 of the integrated stove is inserted into the top of the ventilation base 16. One end of the ventilation base 16 is communicated with the first opening 145, and the other end of the ventilation base 16 is communicated with the air suction port 31 provided on the machine head 3, so that the first opening 145 is communicated with the space above the cooking range. The ventilation base 16 includes a third plate member 161 and a fourth plate member 162 oppositely arranged along the second direction. Both the third plate member 161 and the fourth plate member 162 are abutted between the first side plate 11 and the second side plate 12. The fourth plate member 162 is located on the side of the third plate member 161 away from the first plate member 143. The top of the first plate member 143 is folded downward to form a third folded edge 1432, and the third folded edge 1432 covers the side of the third plate member 161 away from the first plate member 143 along the second direction, so that the back plate 14 and the ventilation base 16 form an integral body, thereby improving the rigidity of the integrated stove main body 1 and also preventing oil fume from leaking between the back plate 14 and the ventilation base 16.

[0088] Further, the ventilation base 16 further includes a fifth plate member 163 and a sixth plate member 164 oppositely arranged along the first direction. The fifth plate member 163 and the sixth plate member 164 are respectively fixedly connected to the first side plate 11 and the second side plate 12. Both the fifth plate member 163 and the sixth plate member 164 are abutted between the third plate member 161 and the fourth plate member 162, thereby fixing the ventilation base 16 between the first side plate 11 and the second side plate 12.

[0089] It can be understood that in this embodiment, the third plate member 161, the fourth plate member 162, the fifth plate member 163 and the sixth plate member 164 are fixed together by welding. Since the first direction affects the dimensional accuracy of the integrated stove main body 1, and in this embodiment, both the fifth plate member 163 and the sixth plate member 164 are abutted between the third plate member 161 and the third plate member 161, that is, the welding method of long side wrapping short side is adopted in this embodiment, so as to ensure the stability of the dimensional chain of the integrated stove main body 1 in the second direction.

[0090] Preferably, a funnel 17 is installed at the bottom of the back plate 14. Based on the above, the integrated stove main body 1 further includes a bottom plate 13.
