Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a range hood. Background Art

[0002] The oil cups of range hoods on the market are generally in the shape of a groove with an opening at the top. In order to ensure the stability of the installation of the oil cup and the range hood body, the oil cup bracket on the range hood body is usually assembled with the oil cup through an interference fit. This will cause a clamping force when the oil cup and the oil cup bracket are assembled, which makes it easy for the oil cup to become unstable when it is taken down after being filled with oil, causing the oil in the oil cup to splash out. The splashed oil may fall on the hands or other places, or even fall into the pot, which will seriously affect the user experience. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the range hood is prone to instability when removing the oil cup, resulting in oil stains in the oil cup splashing out, thereby providing a range hood that can smoothly remove the oil cup.

[0004] The present invention provides a range hood, comprising:

[0005] The machine body has a guide groove and a locking groove on at least one side; the locking groove has a locking position connected to the guide groove and a yielding position offset from the guide groove;

[0006] The oil cup has a slider on at least one side, the slider having a first state of sliding in the guide groove and a second state of being out of the guide groove;

[0007] At least one limiting block is slidably disposed in the locking groove, and the limiting block is extended into the guide groove when in the locking position.

[0008] The guide groove is formed on a side of the machine body facing the oil cup, and the locking groove is formed on a side of the machine body facing away from the oil cup.

[0009] A clearance cavity is provided on at least one side of the machine body, and the clearance cavity is communicated with the guide groove and the locking groove respectively; the projection of the locking position in the direction toward the oil cup falls on the guide groove, and the projection of the clearance position in the direction toward the oil cup falls on the clearance cavity.

[0010] The guide groove is a linear groove.

[0011] The locking groove is arranged obliquely relative to the guide groove, and two ends of the locking groove are respectively the locking position and the yielding position.

[0012] The locking groove comprises:

[0013] a main body section, wherein the lowest point of the main body section is the locking position;

[0014] A yielding section is arranged below the highest point of the main section, and an end of the yielding section away from the main section is the yielding position;

[0015] A transition section connects the highest point of the main section and the yield section.

[0016] The limit block comprises:

[0017] A handle, disposed in the locking groove;

[0018] The engaging portion extends from the handle portion toward the slot width direction of the locking slot and is suitable for abutting against the cavity wall of the yielding cavity.

[0019] The limit block further includes a gripping portion, which is disposed at an end of the handle away from the oil cup, and a length of the gripping portion in a groove width direction of the locking groove is greater than a groove width of the locking groove.

[0020] The slider comprises:

[0021] A connecting portion connected to the oil cup;

[0022] The anti-slip portion is arranged at one end of the connecting portion away from the oil cup and is arranged in the guide groove; the length of the anti-slip portion in the groove width direction of the guide groove is greater than the groove width of the guide groove.

[0023] Slide blocks are respectively arranged on both sides of the oil cup, and a guide groove, a locking groove and a limit block are correspondingly arranged on either side of the two sides of the machine body.

[0024] The machine body comprises an oil tank and a mounting bracket arranged on the oil tank, and the guide groove, the locking groove and the limit block are all arranged on the mounting bracket.

[0025] The technical solution of the present invention has the following effects:

[0026] 1. The range hood provided by the present invention comprises: a body, at least one side of which is provided with a guide groove and a locking groove; the locking groove has a locking position connected to the guide groove, and a yielding position offset from the guide groove; an oil cup, at least one side of which is provided with a sliding block, the sliding block having a first state of sliding in the guide groove, and a second state of being disengaged from the guide groove; at least one limit block, which can be slidably arranged in the locking groove, and the limit block is extended into the guide groove when in the locking position. When the oil cup needs to be removed from the machine body to clean the oil stains in the oil cup, it is only necessary to slide the limit block to move the limit block to the yield position of the locking groove. At this time, there is no limit block in the guide groove, and an external force can be applied to the oil cup to make the slider on the oil cup slide out along the guide groove, so as to remove the oil cup and clean the oil stains; when the oil cup needs to be installed on the machine body, it is only necessary to apply an external force to the oil cup to make the slider on the oil cup slide into the guide groove. After the oil cup is installed in place, the limit block is moved to move the limit block to the locking position in the locking groove. At this time, the limit block will extend into the guide groove, so that the trajectory of the slider sliding outward in the guide groove is blocked by the limit block, thereby preventing the slider from sliding out of the guide groove, so as to achieve a stable installation of the oil cup. In this way, there is no need to make the oil cup's slider and the guide groove of the machine body have an interference fit, so that the oil cup can be securely installed. This can not only achieve secure installation of the oil cup, but also avoid the instability of the oil cup when it is removed due to the interference fit between the oil cup and the machine body. The oil cup can be taken out smoothly, and the oil stains in the oil cup can be effectively prevented from splashing out and affecting the user experience during the process of removing the oil cup.

[0027] 2. In the range hood provided by the present invention, at least one side of the body is provided with a clearance cavity, the clearance cavity is connected with the guide groove and the locking groove respectively; the projection of the locking position in the direction toward the oil cup falls on the guide groove, and the projection of the clearance position in the direction toward the oil cup falls on the clearance cavity. In this way, the limit block can be switched between the locking position interfering with the movement of the slider and the clearance position not interfering with the movement of the slider, and the switching of the limit block between the locking position and the clearance position can be made smoother.

[0028] 3. In the range hood provided by the present invention, the locking groove is arranged obliquely relative to the guide groove, and the two ends of the locking groove are the locking position and the yielding position respectively. By setting the locking position at one end of the locking groove and setting the yielding position at the other end of the locking groove, it is easier to determine the locking position and the yielding position during the process of adjusting the limit block, making the adjustment of the limit block more convenient.

[0029] 4. The range hood provided by the present invention, the locking groove comprises: a main body section, the lowest point of the main body section is the locking position; a yielding section, which is arranged below the highest point of the main body section, and the end of the yielding section away from the main body section is the yielding position; a transition section, which connects the highest point of the main body section and the yielding section. In this way, when no external force is applied to the limit block, the limit block can be maintained in the locking position or the yielding position, so that the state of the limit block in the locking position or the yielding position is more stable.

[0030] 5. In the range hood provided by the present invention, the stop block comprises: a handle portion, which is arranged in the locking groove; and a clamping portion, which extends from the handle portion in the groove width direction of the locking groove and is suitable for abutting against the cavity wall of the clearance cavity. This can prevent the stop block from falling out of the locking groove.

[0031] 6. In the range hood provided by the present invention, the limit block further comprises a gripping portion, the gripping portion is arranged at the end of the handle away from the oil cup, and the length of the gripping portion in the slot width direction of the locking slot is greater than the slot width of the locking slot. The provision of the gripping portion can, on the one hand, prevent the limit block from completely entering the locking slot, which makes it inconvenient to operate the limit block, and on the other hand, can facilitate the adjustment of the position of the limit block in the locking slot by holding the gripping portion.

[0032] 7. In the range hood provided by the present invention, the slider comprises: a connecting portion connected to the oil cup; a stopper portion provided at one end of the connecting portion away from the oil cup and provided in the guide groove; the length of the stopper portion in the groove width direction of the guide groove is greater than the groove width of the guide groove, so as to prevent the slider from falling out of the guide groove.

[0033] 8. In the range hood provided by the present invention, the two sides of the oil cup are provided with sliders, and the two sides of the body are provided with guide grooves, locking grooves and limit blocks. This can make the installation of the oil cup on the body more stable, and can make the movement of the slider in the guide groove more stable during the installation or removal of the oil cup, so that the installation and removal of the oil cup are more stable.

DETAILED DESCRIPTION

[0054] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] like Figure 1-Figure 17 As shown, this embodiment provides a range hood, including a body, an oil cup 3 and a limiting block 7.

[0057] The machine body includes an oil tank 1, and a mounting bracket 2 disposed on the oil tank 1. A guide groove 4 and a locking groove 5 are disposed on either side of the mounting bracket 2. The locking groove 5 has a locking position 51 connected to the guide groove 4, and a yielding position 52 offset from the guide groove 4. The specific connection method between the mounting bracket 2 and the oil tank 1 is not limited. In this embodiment, the mounting bracket 2 and the oil tank 1 are connected by welding. As a convertible embodiment, the mounting bracket 2 and the range hood can also be connected by an integral molding method.

[0058] Slide blocks 6 are respectively provided on both sides of the oil cup 3. The slide blocks 6 have a first state of sliding in the guide groove 4 and a second state of escaping from the guide groove 4.

[0059] There are two limit blocks 7 , which are arranged in one-to-one correspondence with the locking grooves 5 . The two limit blocks 7 are slidably arranged in the corresponding locking grooves 5 , and when the limit blocks 7 are in the locking position 51 , they are extended into the guide groove 4 .

[0060] By providing sliders 6 on both sides of the oil cup 3, and providing guide grooves 4 and locking grooves 5 on either side of the mounting bracket 2, and correspondingly providing limit blocks 7 in the locking grooves 5 on each side, on the one hand, the installation of the oil cup 3 on the machine body can be made more stable, and on the other hand, the movement of the slider 6 in the guide groove 4 can be made smoother during the installation or removal of the oil cup 3, thereby making the installation and removal of the oil cup 3 smoother.

[0061] As a convertible implementation, the guide groove 4 and the locking groove 5 may be provided on only one side of the mounting bracket 2, and correspondingly, the slider 6 may be provided on only one side of the oil cup 3, and there may be only one limit block 7.

[0062] The specific arrangement of the guide groove 4 and the locking groove 5 is not limited. In this embodiment, the guide groove 4 is opened on the side of the body facing the oil cup 3, and the locking groove 5 is opened on the side of the body facing away from the oil cup 3.

[0063] In order to enable the limit block 7 to switch between the locking position 51 that interferes with the movement of the slider 6 and the yielding position 52 that does not interfere with the movement of the slider 6, and to make the switching of the limit block 7 between the locking position 51 and the yielding position 52 smoother, in the present embodiment, at least one side of the machine body is provided with a yielding cavity 8, which is connected with the guide groove 4 and the locking groove 5 respectively; the projection of the locking position 51 in the direction toward the oil cup 3 falls on the guide groove 4, and the projection of the yielding position 52 in the direction toward the oil cup 3 falls on the yielding cavity 8.

[0064] The specific shape of the guide groove 4 is not limited. The guide groove 4 in this embodiment is a linear groove. As a convertible implementation, the guide groove 4 can also be a broken line groove or an arc groove.

[0065] In this embodiment, the locking groove 5 is arranged obliquely relative to the guide groove 4, and the two ends of the locking groove 5 are respectively a locking position 51 and a yielding position 52. By setting the locking position 51 at one end of the locking groove 5 and setting the yielding position 52 at the other end of the locking groove 5, it is easier to determine the locking position 51 and the yielding position 52 during the adjustment of the limit block 7, making the adjustment of the limit block 7 more convenient. As a convertible embodiment, the locking position 51 and the yielding position 52 may not be set at the ends of the locking groove 5.

[0066] The specific structural form of the locking groove 5 is not limited. The locking groove 5 in this embodiment includes a main section 53 , a yielding section 54 and a transition section 55 .

[0067] The lowest point of the main body section 53 is the locking position 51 .

[0068] The yielding section 54 is arranged below the highest point of the main section 53 , and one end of the yielding section 54 away from the main section 53 is the yielding position 52 .

[0069] The transition section 55 connects the highest point of the main section 53 and the clearance section 54 .

[0070] In this way, when no external force is applied to the limit block 7 , the limit block 7 can be maintained at the locking position 51 or the yielding position 52 , so that the state of the limit block 7 at the locking position 51 or the yielding position 52 is more stable.

[0071] As a convertible implementation, the lowest point of the main body section 53 may be the yielding position 52 , and the end of the yielding section 54 away from the main body section 53 may be the locking position 51 .

[0072] As a convertible embodiment, the locking groove 5 may also include only a main section 53 and a straight section, wherein the straight section extends horizontally from the highest point of the main section 53, so that one of the end of the straight section away from the main section 53 and the lowest point of the main section 53 can be set as the locking position 51, and the other can be set as the yield position 52.

[0073] The specific structural form of the limiting block 7 is not limited. In order to effectively prevent the limiting block 7 from escaping from the locking groove 5 , the limiting block 7 in this embodiment includes a handle portion 71 and a clamping portion 72 .

[0074] The handle 71 is disposed in the locking groove 5 .

[0075] The engaging portion 72 extends from the handle 71 in the slot width direction of the locking slot 5 and is suitable for abutting against the cavity wall of the yield cavity 8 .

[0076] As a convertible implementation, the limiting block 7 may also only include the handle portion 71 without the engaging portion 72 .

[0077] Furthermore, the limit block 7 in this embodiment also includes a gripping portion 73, which is arranged at one end of the handle 71 away from the oil cup 3, and the length of the gripping portion 73 in the groove width direction of the locking groove 5 is greater than the groove width of the locking groove 5. The provision of the gripping portion 73, on the one hand, can prevent the limit block 7 from completely entering the locking groove 5, which makes it inconvenient to operate the limit block 7, and on the other hand, it can facilitate the adjustment of the position of the limit block 7 in the locking groove 5 by holding the gripping portion 73. The specific shape of the gripping portion 73 is not limited, and the gripping portion 73 in this embodiment is cylindrical. As a convertible embodiment, the gripping portion 73 may also be prismatic. As a convertible embodiment, the limit block 7 may also not include the gripping portion 73.

[0078] The specific structural forms of the slider 6 can be various. In order to effectively prevent the slider 6 from falling out of the guide groove 4 , the slider 6 in this embodiment includes a connecting portion 61 and a stopper portion 62 .

[0079] The connection portion 61 is connected to the oil cup 3 .

[0080] The anti-slip portion 62 is disposed at one end of the connecting portion 61 away from the oil cup 3 and in the guide groove 4 ; the length of the anti-slip portion 62 in the groove width direction of the guide groove 4 is greater than the groove width of the guide groove 4 .

[0081] As a convertible embodiment, the slide block 6 may also only include the connecting portion 61 , and in this case the connecting portion 61 is directly extended into the guide groove 4 .

[0082] When the oil cup 3 needs to be removed from the machine body to clean the oil stain in the oil cup 3, it is only necessary to slide the limit block 7 to move the limit block 7 to the yield position 52 of the locking groove 5. At this time, there is no limit block 7 in the guide groove 4. An external force can be applied to the oil cup 3 to make the slider 6 on the oil cup 3 slide out along the guide groove 4, so that the oil cup 3 can be removed and the oil stain can be cleaned; when the oil cup 3 needs to be installed on the machine body, it is only necessary to apply an external force to the oil cup 3 to make the slider 6 on the oil cup 3 slide into the guide groove 4. After the oil cup 3 is installed in place, the limit block 7 is moved to make the limit block 7 move to the locking position 51 in the locking groove 5. At this time, the limit block 7 will extend into the guide groove 4, so that the trajectory of the slider 6 sliding outward in the guide groove 4 is blocked by the limit block 7, thereby causing the slider 6 to be unable to slide out of the guide groove 4, so as to achieve a stable installation of the oil cup 3. In this way, there is no need to make an interference fit between the slider 6 of the oil cup 3 and the guide groove 4 of the body, so that the oil cup 3 can be firmly installed. Therefore, the oil cup 3 can be firmly installed, and the instability of the oil cup 3 caused by the interference fit between the oil cup 3 and the body when the oil cup 3 is removed can be avoided. The oil cup 3 can be smoothly taken out, and the oil stains in the oil cup 3 can be effectively prevented from splashing out and affecting the user experience during the process of removing the oil cup 3.

[0083] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
