日本特許第4874765號專利,揭露了另一種空調裝置用的排水泵,其馬達部外殼(圖號2)頂部設有不等角分佈的三個固定腳,而可用來安裝在空調裝置上。此外,馬達外殼的上板體與中間的泵部殼體(圖號1)之間的固定方式,同樣是由馬達部外殼向外延伸複數凸耳(圖號21),且由泵部殼體向外延伸複數取付部(圖號12),以螺栓穿過凸耳來鎖固於取付部,藉此將馬達部固定在泵部殼體上。 Japanese Patent No. 4874765 discloses another drainage pump for an air-conditioning device. The top of the motor housing (Figure No. 2) is provided with three fixed feet with unequal angular distribution, which can be used to install on the air-conditioning device. In addition, the fixing method between the upper plate of the motor housing and the middle pump housing (figure number 1) is also by extending the plurality of lugs (figure number 21) from the motor housing Extend a plurality of take-and-attach parts (Figure No. 12), and use bolts to pass through the lugs to lock to the take-and-attach part, thereby fixing the motor part on the pump housing.
日本特許第5934515號專利,還揭露了一種空調裝置用的排水泵,其整體外殼是一個容置馬達以及部分馬達部件的殼體,而在這個殼體上段 位置容置馬達(圖號60),在殼體的中段位置則容置馬達部件(驅動軸(圖號110)及擋水板(圖號30))。此案在殼體的頂緣設有三個固定腳,而可用來安裝在空調裝置上,此外,由該案的圖4可知,馬達外殼還設置了凸部來與殼體的取付穴相結合。 Japanese Patent No. 5934515 also discloses a drain pump for an air-conditioning device. The integral shell is a shell that houses the motor and part of the motor components, and the upper section of the shell The motor (figure number 60) is placed in the position, and the motor parts (drive shaft (figure number 110) and the water baffle plate (figure number 30)) are housed in the middle of the housing. In this case, there are three fixed feet on the top edge of the shell, which can be used to install on the air conditioner. In addition, as can be seen from Figure 4 of the case, the motor shell is also provided with a convex portion to be combined with the taking hole of the shell.
由前述的已知技術可知,在排水泵上設置固定腳時,還需要考慮到設置在殼體內頂部的馬達的配置關係,因此,才會有上述不同態樣的實施方式。 It can be known from the aforementioned known technology that when a fixed foot is provided on the drain pump, it is also necessary to consider the configuration relationship of the motor provided on the top of the casing. Therefore, the above-mentioned different aspects of implementation are available.
上述的已知技術中,其固定腳若是設置在殼體最上方的蓋體或是在馬達外殼頂端,則由於下方的殼體是另外再藉由連接件來連接於上方的蓋體或是馬達外殼,因此其整體的結構將比較鬆散,較容易因組裝間隙而在運轉時產生噪音或是振動。而上述已知技術中,若固定腳是設置在殼體上,則又有馬達外殼與殼體組裝時的凸部及取付穴的配合問題。 In the above-mentioned known technology, if the fixed foot is provided on the uppermost cover of the housing or on the top of the motor housing, the lower housing is additionally connected to the upper cover or motor by a connecting piece. The shell, therefore, the overall structure will be relatively loose, and it is easier to generate noise or vibration during operation due to the assembly gap. However, in the above-mentioned known technology, if the fixed feet are provided on the housing, there are problems with the matching of the protrusions and the extraction holes when the motor housing and the housing are assembled.
本發明提出一種具有安裝結構的空調裝置用之排水泵,其固定腳是設置在主要的殼體上,而且不會有馬達外殼與殼體間組裝的問題,而且固定腳也不會干涉到蓋體,結構上與目前的已知技術不同。 The present invention provides a drainage pump for an air conditioner with a mounting structure.
