Sum columns with similar value- SQL - mysql

Question

I need to sum all fields that have similar value.
I have a simple SQL query that give me back this result:
For example, the name like 'Climatizzazione' has to be sum to 'Climatizzatori Samsung' and 'Climatizzatori Daiki' and get a unique result.
The final result would be like that:
| name | totale_fatturato |
| -------- | -------------- |
| Climatizzazione | 535.241,583465|
| Scaldabagni| 90680,77684|
| Differenziali e Magnetotermici| 78511,185704|
ecc.......
This is my SQL query:
SELECT
cl.name,
SUM(od.total_price_tax_excl) AS totale_fatturato
FROM `ww_ps_order_detail` AS `od`
INNER JOIN `ww_ps_product` AS p ON od.product_id = p.id_product
INNER JOIN `ww_ps_category_lang` AS cl ON p.id_category_default = cl.id_category
WHERE od.ID_ORDER IN (
SELECT ID_ORDER
FROM ww_ps_orders
WHERE 1=1 AND DATE_ADD >= DATE_SUB(NOW(), INTERVAL 30 DAY)) AND cl.id_lang = 1
GROUP BY name
ORDER BY totale_fatturato DESC
LIMIT 10
What i have to do for get the result i want? Thx!

Thanks to Akina, Jonas Metzler and Trillion, i found my solution.
So, how you have suggest me, i create a supplementary column with some cases where i can handle all the exceptions and group by this column.
This is my result:
SELECT
cl.name AS NAME,
SUM(od.total_price_tax_excl) AS `totale_fatturato`,
CASE
WHEN cl.name LIKE 'Climatizza%' THEN 'Climatizzazione'
/* SOME OTHER CASES */
ELSE cl.name
END AS groupName
FROM `ww_ps_order_detail` AS `od`
INNER JOIN `ww_ps_product` AS p ON od.product_id = p.id_product
INNER JOIN `ww_ps_category_lang` AS cl ON p.id_category_default = cl.id_category
WHERE od.ID_ORDER IN (
SELECT ID_ORDER
FROM ww_ps_orders
WHERE 1=1 AND DATE_ADD >= DATE_SUB(NOW(), INTERVAL 30 DAY)) AND cl.id_lang = 1
GROUP BY groupName
ORDER BY totale_fatturato DESC
