Description

Technical Field

[0001] The present invention relates to the field of household integrated stoves, and in particular to a split volute for an integrated stove. Technical Background

[0002] At present, when the integrated stoves on the market are in use, the volute impeller is very easy to be contaminated with oil smoke. If it is not cleaned for a long time, it is easy to reduce the oil smoke cleaning rate of the integrated stove. However, cleaning the impeller and volute requires the entire fan volute to be disassembled and assembled, which is time-consuming and inconvenient. The motors of the integrated stoves on the market are all installed on the volute. Since the vibration of the motor cannot be eliminated, it will cause noise problems in the integrated stove. Each time the volute is disassembled, it needs to be realigned with the mounting hole under the negative pressure box, which is easy to cause flow loss and flow reduction of the fan, resulting in reduced fan performance.

[0003] Therefore, in order to facilitate the cleaning of the volute impeller, the convenience of volute disassembly and the ease of installation, it is necessary to make certain improvements to the traditional integrated stove volute structure and the motor fixing position to reduce the energy loss of the fan, increase the air volume and air pressure, reduce noise, and simplify the volute installation process. Summary of the invention

[0004] In order to overcome the disadvantage of the complexity of disassembling the impeller of the volute of a traditional integrated stove for cleaning and maintenance, to reduce the disturbance of the installation hole opening when the volute is installed, and to reduce the noise problem of the volute caused by the vibration of the motor, the present invention provides a split volute for an integrated stove.

[0005] The technical solution adopted by the present invention is:

[0006] A split volute for an integrated stove, comprising a volute, a spring housing lock, a box body, a fixing frame, a motor and a motor bracket;

[0007] The height of the volute is H, and the volute is divided into an upper volute, and the height of the upper volute is h; the upper volute is fixed with a spring housing lock and a latch structure at the cut ends on both sides; the spring housing lock is fixed at the middle position of the width of the upper volute except for the lock buckle part, and the spring housing lock is connected with the latch; the latch structure is fixed at the cut end, the extended length of the latch is L1, and the latch width is equal to the volute width d; the volute is divided into a lower volute; the lower volute is fixed with a lock buckle and an installation slot at the cut ends on both sides; the lock buckle is fixed at the middle position of the width of the upper volute of the lower volute, and the lock buckle is connected with the installation slot; the length of the installation slot is the width of the volute; the installation slot is embedded with a rubber gasket;

[0008] The motor is fixed on the motor bracket, the motor bracket is fixed on the box body, the axis position of the motor bracket is consistent with the axis position at the inlet end of the volute, and the lower volute is fixed on the box body through a fixing frame.

[0009] Furthermore, the shell spring lock includes a handle, a spring, a bearing rod, a base and a locking ring. The interior of the handle is hollow, the bearing rods are fixed at the front end of the handle, and the spring is fixed inside the handle and in the middle of the bearing rods; the locking ring is fixed on the bearing rod, and the handle is fixed to the base through the bearing rod.

[0010] Preferably, the height of the upper volute is h; h=40%×H; the length of the latch is L1; L1=d×7%.

[0011] The working principle of the present invention is as follows: when cleaning and maintaining the range hood, the volute is disassembled, the two volute spring locks (20) fixed on the volute are separated from the lock buckle (a) respectively, and the upper volute (11) is taken out from the installation slot (q) of the lower volute (12) to separate the volute; the lower volute (11) is fixed on the fixing frame (40), and the latch (p) is inserted into the installation slot (q) during installation to lock the housing spring lock (20). The motor bracket (60) is fixed on the housing (30) by welding, and the axis position of the motor bracket (70) is consistent with the axis position at the inlet end of the volute (10); the lower volute (12) is fixed together with the fixing plate (40), and does not need to be moved during disassembly, thereby maintaining the accuracy of the position of the housing and the installation hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Compared with the traditional integral volute design, the split volute for an integrated stove of the present invention has a spring housing lock fixed on the surface of the volute, which makes it easy to disassemble and install the volute, saving time and effort.

[0014] 2. The split volute for an integrated stove of the present invention reduces the disturbance of the opening of the lower mounting hole and facilitates the modification design of the shell.

[0015] 3. The conventional motor is installed on the volute, and the vibration of the motor is transmitted to the volute, causing noise. The present invention provides a split volute for an integrated stove, and the motor is installed on the negative pressure box, which reduces the vibration of the volute and improves the efficiency of the fan.

[0016] 4. The present invention provides a split volute for an integrated stove, which facilitates the cleaning and maintenance of the volute impeller and is more convenient.

[0017] 5. The present invention provides a split volute for an integrated stove; the upper and lower volutes are respectively provided with latches and mounting slots, which are convenient for positioning and fixing the installation position without damaging the volute profile structure.
